Description

The roller press of machined steel roll bending inner protective corner circle

The utility model relates to a kind of roller press of machined steel roll bending inner protective corner circle.

The machine-shaping of inner protective corner circle in the prior art, generally be with sheet material by certain-length cut off, bending again, cans on make-up machine at last.Problem is, the overlap joint intersection of the jointing edge of the inner protective corner circle of machine-shaping can not well be fitted by the length of material restriction and had alice like this, so that its alice scratches people or thing easily when using this corner protector circle.

The purpose of this utility model is exactly the roller press that a kind of machined steel roll bending inner protective corner circle is provided at the problems referred to above, can not hang, draw people or thing because of not having alice by the mach inner protective corner circle of this roll extrusion.

The technical solution of the utility model is, a kind of roller press of machined steel roll bending inner protective corner circle, comprise a pair of pressure roller that drives through the transmission loading amount by motor, be located at the control wheel of pressure roller one side and cooperate the Control Shaft that workpiece is curled with the control wheel, its special character is to be provided with a shear that in continuous process shaping workpiece is cut off.

And shear has one allows the cover die of roll extrusion cans workpiece from passing between its power and stationary knife, and the support of shear is contained on the circular arc guided way by roller.

And stationary knife is fixedly arranged on the cover die, and moving knife is connected with the piston rod of hydraulic cylinder.

And shear has a centre of gyration that moves along guided way, and shear is connected with rotary middle spindle by pivoted link.

And pivoted link one end is provided with oval shape or the elongated hole that allows rotary middle spindle stretch into, and the shear support is provided with roller shaft, and roller shaft is provided with can be along the roller of its axial adjustment.

And, on the opposite direction of workpiece motion s, being provided with a balancing weight that makes the shear self-return, balancing weight is connected with shear by the hawser pulley mechanism.

And the shape of the stationary knife and the moving knife edge of a knife matches with the truncation surface shape that is positioned at workpiece between the two.

The utility model is owing to be provided with a shear that in continuous process shaping workpiece is cut off, and the utility model will be with steel at roll extrusion cans after the preceding working procedure bending and in the roll extrusion curly course molded workpiece is cut off like this.Shear after because of first moulding thereby its overlap joint intersection fits tightly and do not have alice by the inner protective corner circle of the utility model machine-shaping, in use can not hang, draw people or thing especially coil of strip or steel roll package paper.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1, and wherein shear is the cutaway view at A-A place.

Referring to Fig. 1, Fig. 2, the utility model comprises a pair of

pressure roller

10,11 that is driven through transmission device 12 by motor 13, be located at the control wheel 9 of

pressure roller

10,11 1 sides and cooperate the

Control Shaft

27,28 that workpiece 7 is curled with control wheel 9, control wheel 9 is installed on the control wheel seat 16 by bearing 17, the workpiece inlet side of

pressure roller

10,11 is provided with directive wheel 24 and feed block 25, go out end and be provided with discharging piece 26, Control Shaft 27,28 is positioned near discharging piece 26 and the control wheel 9, and Control Shaft 27,28 and directive wheel 24 can be selected bearing for use.Shear 1 of the present utility model has one allows roll extrusion cans workpiece 7 from its moving

knife

3 and 4 cover dies that pass 5 of stationary knife, stationary knife 4 is installed on the cover die 5, moving knife 3 is connected with the piston rod 2 of hydraulic cylinder 23, hydraulic cylinder 23 also is packed on the cover die 5, the support 22 of shear 1 is provided with roller 19, and the utility model also is provided with the circular arc guided way 18 that moves for shear 1 thereon.In addition, also can establish a central shaft (being provided with in the center that is being sheared workpiece 7), and be connected with shear 1 by pivoted link 6 at the center of circular arc guided way 18 as the control wheel shaft 8 among Fig. 1 or other.

For adapting to the different size requirement of product to be processed, pivoted link 6 one ends of the present utility model are provided with oval shape or the elongated hole 30 that allows rotary middle spindle 8 stretch into, rotary middle spindle 8 is fastened on the appropriate location of waist circular port 30, the position of promptly satisfying the dimensional requirement of product to be processed by bolt 29.Simultaneously, corresponding adjustment also should be done in roller position on the shear support 22, and this can 20 move axially to fastening or roller support 21 and shear support 22 be made as slidably regulate and finish by the fastening mode of securing member with securing members such as nuts again with above-mentioned dimensional requirement consistent location along it by roller 19.

Reset for after shear 1 being finished once shear, the utility model is provided with a balancing weight 15 that makes shear 1 self-return on the opposite direction of workpiece motion s, and balancing weight 15 is connected with shear 1 by hawser pulley mechanism 14.

This newly can be determined according to the truncation surface that is sheared workpiece with the edge of a knife shape of type moving knife 3 and stationary knife 4.Because of the shearing truncation surface of inner protective corner circle is rectangular in shape substantially, then moving knife and stationary knife should match with it, and promptly the edge of a knife is shaped as right angle or bigger (little) in the right angle (85～95 °).

The course of work of the present utility model is as follows:

pressure roller

10,11 turn round under the driving of motor 13, by the workpiece 7 of preceding working procedure bending through directive wheel 24, feed block 25 is by

pressure roller

10,11,

pressure roller

10,11 are fed forward workpiece in the roll-in flanging, making the flanging of workpiece paste discharging piece 26 moves ahead, the another side both sides of workpiece recline respectively and control wheel 9 and Control Shaft 27,28, workpiece 7 is at pressure roller 10 like this, controlled ratch 9 and Control Shaft 27 under 11 the driving, 28 the effect and curl, the workpiece 7 that is curled passes cover die 5, when said process is finished a Workpiece length curling, default travel switch starts, make hydraulic cylinder 23, promote moving knife 3 clamping work pieces 7, when this moment, shear 1 moved along circular arc guided way 18 along with workpiece 7 workpiece 7 is cut off, after shear 1 is finished and is once sheared, hydraulic cylinder 23 drives moving knife 3 and resets, and at this moment, shear 1 is subjected to the effect of balancing weight 15 to get back to start position along guided way 18.Because

pressure roller

10,11 is continuously rotating, thereby above-mentioned shear history also constantly repeats.Making that the inner protective corner circle is constantly processed comes out.Its overlap joint intersection of the inner protective corner circle that obtains thus can well be fitted and do not had the perk limit.

Different size requirement for product to be processed, the utility model can by regulate rotary middle spindle 8 in the position of the waist circular port 30 of pivoted link 6 and the axial distance of roller 19 to change the radius of gyration, the diameter of product to be processed can reach requirement by regulating

Control Shaft

27,28.
