Abstract

The utility model relates to a dual mechanical leather punching device which comprises a machine frame, a drive motor mounted on the machine frame, two eccentric wheel seats and two punching rod locating seats, wherein a synchronous pulley is mounted on an output shaft of the drive motor, the two eccentric wheel seats are respectively connected through a transmission shaft, and cams are arranged on end portions of the transmission shaft. The middle of the transmission shaft is provided with a synchronous pulley connected with the synchronous pulley mounted on the output shaft of the drive motor through a synchronous belt, punching rods which can ascend and descend are arranged on both of the two punching rod locating seats, and the punching rods are provided with elastic devices which enable the punching rods to be located on high posts of the two punching rod locating seats all the time without exogenic action. The upper ends of the punching rods are connected with cam surfaces of the cams in a matched mode, the lower ends of the punching rods are provided with punches, the drive motor drives the transmission shaft to rotate so as to drive the cams mounted at two ends of the transmission shaft to rotate synchronously, and the cam surfaces of the cams drive the punching rods to ascend and descend on the punching rod locating seats. The dual mechanical leather punching device can improve processing efficiency.

Description

A kind of two group mechanical type leather punching apparatus

Technical field

The utility model relates to a kind of two group mechanical type leather punching apparatus.

Background technology

Existing leather processing has kinds of schemes, and common has: 1, according to punching figure mfg. moulding die, be placed on the punch press and process, this method production cycle is long, and die manufacturing cost is high; 2, use the laser cutting machine hole burning, the leather surface after the processing can be burnt blackout, influences the quality of product and attractive in appearance; 3, use the cylinder punching, this working method noise is big, and cylinder is short work-ing life, has increased use cost; 4, single group mechanical type punched hole equipment, though this punching mode is changing than in the past equipment on the working (machining) efficiency, qualitatively and on the noise to some extent, because a drive-motor can only drive a jumper bar, production efficiency is still lower.

Summary of the invention

The purpose of the utility model is to provide a kind of working (machining) efficiency high two group mechanical type leather punching apparatus.

The purpose of the utility model is achieved in that a kind of two group mechanical type leather punching apparatus; Comprise frame (1), be installed in drive-motor (2), two eccentric wheel seats (3), two jumper bar positioning seats (4) on the frame (1); Synchronous pulley (20) is installed on the output shaft of said drive-motor (2); Said two eccentric wheel seats (3) connect through a transmission shaft (5) respectively, are provided with cam (6) in the end of transmission shaft (5), and the middle part of transmission shaft (5) is provided with another synchronous pulley (20); Two synchronous pulleys (20) are through band (7) connection synchronously; Said two jumper bar positioning seats (4) but on be respectively fitted with the jumper bar (8) of oscilaltion, jumper bar (8) is provided with and makes jumper bar (8) under no external force effect, be positioned at jumper bar positioning seat (4) elevated elastic device (9) all the time, the cam surface of the upper end of jumper bar (8) and cam (6) is connected; The lower end is equipped with drift (10); Drive-motor (2) drives transmission shaft (5) rotation, drives cam (6) rotation synchronously that is installed in transmission shaft (5) two ends, and the cam surface of cam (6) drives jumper bar (8) and goes up oscilaltion at jumper bar positioning seat (4).

Said elastic device (9) is a spring, and jumper bar (8) middle part has a boss (80), and spring one end is resisted against on the jumper bar positioning seat (4), and the other end is resisted against boss (80) bottom, makes jumper bar (8) under no external force effect, be positioned at jumper bar positioning seat (a 4) high position all the time.

The beneficial effect of the utility model: on existing single group mechanical type leather punching apparatus basis; Form two group mechanical type leather punching apparatus through texture improvement; Because drive-motor is the two groups of jumper bar work that directly drive, therefore existing relatively technology has the following advantages; 1, uses punch press perforated with short production cycle than traditional mfg. moulding die, saved die manufacturing cost; 2, relative laser cutting machine hole burning has improved the quality of production of product, has improved the outward appearance of product, has increased the market competitiveness of finished product; 3, littler than using the perforated noise of cylinder, cylinder is short work-ing life, and use cost is high, has reduced production cost; 4, single mechanical type punched hole mechanism that organizes once can only dash a product; But two groups of mechanical type leather punch mechanisms once can be gone out two products simultaneously; Two groups of mechanical type leather punch mechanism manufacturing costs change little; But perforated efficient almost can be doubled, and has reduced the perforated tooling cost of leather effectively.

Description of drawings

Fig. 1 is two group mechanical type leather punching apparatus structural representations.

Embodiment

Below in conjunction with accompanying drawing the embodiment of the two group of the utility model mechanical type leather punching apparatus is done further explain.

As shown in Figure 1, two group mechanical type leather punching apparatus of the utility model mainly are made up of frame 1, drive-motor 2, the two eccentric wheel seats 3 and the two jumper bar positioning seats 4 that are installed on the frame 1; Synchronous pulley 20 is installed on the output shaft of drive-motor 2; Two eccentric wheel seats 3 connect through a transmission shaft 5 respectively, are provided with cam 6 in the end of transmission shaft 5, and the middle part of transmission shaft 5 is provided with another synchronous pulley 20; Two synchronous pulleys 20 are through be with 7 to connect synchronously; But be respectively fitted with the jumper bar 8 of oscilaltion on the two jumper bar positioning seats 4, jumper bar 8 is provided with and makes jumper bar 8 under no external force effect, be positioned at jumper bar positioning seat 4 elevated elastic devices 9 all the time, and the cam surface of the upper end of jumper bar 8 and cam 6 is connected; The lower end is equipped with drift 10; Drive-motor 2 drives transmission shaft 5 rotations, drives the cam 6 that is installed in transmission shaft 5 two ends and rotates synchronously, and the cam surface of cam 6 drives jumper bar 8 oscilaltion on jumper bar positioning seat 4.Elastic device 9 adopts spring usually, has a boss 80 at jumper bar 8 middle parts, and spring one end is resisted against on the jumper bar positioning seat 4, and the other end is resisted against boss 80 bottoms, makes jumper bar 8 under no external force effect, be positioned at jumper bar positioning seat 4 high positions all the time.
