Referring to fig. 7, the guide wire straightening device 50 includes a discharge end 51, and a lower end surface of the discharge end 51 is flush with a radial top of the mandrel body 31. By limiting the lower end face of the discharge end 51, the straightened wire extending from the discharge end 51 can be tightly attached to the mandrel body 31. The wire is not flush during the forming process, which does not have a major effect on the formation of the helical segment 12, but makes it difficult to straighten the straight segment 11. And the limitation of the parallel and level enables the metal wire to be tightly attached to the mandrel body 31, so that the mandrel body 31 is used as a reference and matched with a guide wheel auxiliary device to realize plastic deformation of the straight line segment 11 of the series spiral metal wire, and the series spiral metal wire with better quality is obtained. Referring to fig. 7 and 8, the discharge direction of the discharge end 51 forms an acute angle with the extending direction of the axis of the spindle body 31 on the side close to the first driving mechanism 32, which corresponds to the angle a in fig. 8 1 .

According to different requirements for the helix angle of the helical segment 12, the angle a can be diagonal 1 Different adjustments are made, a 1 Is ninety degrees minus the angle of the helix angle. Angle a 1 Is acute to avoid unnecessary obstruction of the volume of the guide wire straightening device 50 by other components. When the discharge direction of the discharge end 51 is parallel to the axis of the mandrel body 31, i.e. angle a 1 At zero degrees, the guide wire straightening device 50 is often required to be partially arranged above the mandrel body 31, so that certain obstruction is generated for assembly of various structures and wire discharging; while when angle a 1 At right angles or at obtuse angles, the formation of the helical segment 12 is hindered. Root of Chinese characterThe structure of the guide wire straightening device 50 can be set according to different needs. Preferably, referring to fig. 7 and 9, the guide wire straightening device 50 comprises a sheave right angle bracket 52 and seven sheave assemblies, each sheave assembly comprising a sheave body 53, a sheave flange pin 531 and a sheave wear pad 532; the sheave right-angle bracket 52 is arranged on the mounting plate assembly 42, the sheave body 53 is sleeved on the sheave flange pin 531, the cylindrical section of the sheave flange pin 531 is in clearance fit with the hole of the sheave right-angle bracket 52, and the sheave flange pin 531 is fixed on the sheave right-angle bracket 52 through a nut.

The guide wheel auxiliary device is used for auxiliary forming of the straight line segment 11 after the spiral segment 12 is formed; the subsequent procedures of cutting, hammering and the like are reduced, and the production efficiency is improved. A guide wheel assist device is provided on the mounting plate assembly 42, the guide wheel assist device including a first guide wheel 611 and a second guide wheel 612. The first guide wheel 611 and the second guide wheel 612 are rotatably disposed on a side of the discharge end 51 away from the first driving mechanism 32, so as to ensure that the auxiliary forming of the straight line segment 11 can be realized. The first guide wheel 611 and the second guide wheel 612 are sequentially arranged along the second direction 22 and are respectively located at two sides of the mandrel body 31, and the wheel surfaces of the first guide wheel 611 and the second guide wheel 612 are abutted against the surface of the metal wire, so that the metal wire can be ensured to form the straight line segment 11 under the common force application of the first guide wheel 611, the second guide wheel 612 and the mandrel body 31. The axis of the first guide wheel 611 and the axis of the second guide wheel 612 are parallel to each other, and the axis of the first guide wheel 611 and the axis of the second guide wheel 612 are perpendicular to the axis of the mandrel body 31, so that the problem of wire quality caused by angle factors of the guide wheels in the forming process is reduced, and the product quality is effectively ensured. Referring to FIG. 10, the axis of the first guide pulley 611 A line segment formed by connecting any point on the upper surface and any point on the axis of the second guide wheel 612 and a straight line formed by projection of the line segment on the frame assembly 20 form an acute angle with the axis of one side of the mandrel body 31, which is close to the first driving mechanism 32; this angle corresponds to angle a in fig. 10 2 . With respect to the definition of this structure, the limitation is in the first direction 21, the first guide wheel 611 being located between the discharge end 51 and the second guide wheel 612, so as to ensure that the first guide wheel 611 and the second guide wheel 612 are able to act as a transition, guide and stop for both the wire that has been shaped into the helical segment 12 and the wire that is to be shaped into the straight segment 11; and for transitions, guides and stops between the wire that has been shaped into the straight section 11 and the wire that is to be shaped into the straight section 11. Considering the requirements of different types of serial spiral metal wires, different settings can be made for the wheel diameters, the wheel surface area sizes and the like of the two guide wheels. For example, the diameters of the wheels are equal or unequal, and the areas of the wheel surfaces are equal or unequal. Considering the aesthetic appearance of the final tandem spiral wire, i.e. the axes of the different straight sections 11 are all on the same straight line, two identical guide wheels are selected, and the axes of both are perpendicular to the frame assembly 20, so as to ensure convenient positioning, thereby producing the aesthetic tandem spiral wire. Preferably, under the premise of identical structure and vertical axis, the distances from the axes of the two guide wheels to the axis of the mandrel body 31 are equal, so that the straight line segment 11 can be positioned at the center of the mandrel body 31, and the observation, measurement and the like are convenient. This is of course not necessary as long as it is ensured that the two guide wheels are able to achieve an auxiliary shaping of the straight segment 11. Due to the arrangement of the device, the spiral section 12 and the straight line section 11 are obtained by directly plastically deforming the metal wire, so that the contact resistance of the spiral section 12 and the straight line section 11 can be kept consistent, and the problems of heating, service life reduction, potential safety hazard and the like caused by large contact resistance when the product is used are avoided.
Working principle: when production is not being performed, the mounting plate assembly 42 is displaced to a position away from the first drive mechanism 32 to ensure that production is enabled. In the actual production process, the wire is straightened and fed by the wire straightening device 50; the power-on straight line section 111 is bent by manual bending, automatic machine bending and the like so that the axis of the power-on straight line section is parallel to the axis of the mandrel body 31, and the power-on straight line section is fixed on the mandrel body 31 through the locking clamp 33. The mandrel body 31 is rotated by driving the first driving mechanism 32, and the mounting plate assembly 42 is moved by driving the second driving mechanism 41, so that the guide wire straightening device 50 and the guide wheel auxiliary device arranged on the mounting plate assembly 42 are driven to move together to generate the spiral section 12 on the mandrel body 31. The length of the spiral section 12, the pitch and the length of the straight section 11 can be set according to practical requirements. After the shaping of the helical segment 12 is completed, the first driving mechanism 32 is stopped so that the mandrel body 31 does not rotate; the second drive mechanism 41 is driven to move the mounting plate assembly 42, during which the tread of both the first guide pulley 611 and the second guide pulley 612, the mating mandrel body 31, cooperate to bend the wire of the rear portion of the shaped helical segment 12, thereby enabling the guide pulley assist device to effect shaping of the straight segment 11. Then, the locking clip 33 is released and reattached to the now-produced straight segment 11; after the fixed locking is completed, the spiral section 12 and the straight section 11 are repeatedly formed at intervals, and after the spiral section 12 and the straight section 11 with the required number are formed, the spiral section 12 and the straight section 11 are cut off to obtain a semi-finished serial spiral metal wire. And bending the straight line segment 11 between two adjacent spiral segments 12 of the semi-finished product serial spiral metal wire to obtain the finished product serial spiral metal wire. The series spiral metal wire is used as a resistance furnace heating resistance wire, and the straight line segment 11 can be bent differently according to different resistance furnace requirements. Taking a semi-finished product of two spiral sections 12 as an example, a series of spiral wires, the straight line section 11 between the two spiral sections 12 is bent at right angles on the same plane symmetrically twice so that the axes of the two spiral sections 12 are parallel. Taking a semi-finished product of a plurality of spiral sections 12 as an example, bending straight sections 11 between adjacent spiral sections 12 according to the same method to obtain a series spiral metal wire with parallel axes of the plurality of spiral sections 12; or further processing on the basis of the circular arc external regular polygon distribution or circular arc distribution series spiral metal wires, wherein the axes of the spiral sections 12 are parallel. The meaning of the circular arc distribution is that the straight segment 11 between the two spiral segments 12 is machined to a circular arc transition. Of course, in consideration of the structure of the spring, particularly the tension spring, the processing can be performed by the apparatus of the present invention by forming only one spiral segment 12 and the straight segments 11 at both ends thereof, and then forming the two straight segments 11 into a hook shape. In some embodiments, wire shaping at different helix angles can also be achieved by providing the wire straightening device 50 with a rotating mechanism to adjust the discharge direction of the discharge end 51.
