Description

Technical Field

[0001] This utility model relates to the field of punch press accessories technology, specifically a quick clamping mechanism for metal punch presses. Background Technology

[0002] Punch presses are mainly used to punch and cut metal materials using dies. With pressure as the core, through the cooperation of punches and dies, they can perform cold processing such as punching, bending, stretching, and forming of metal sheets and profiles, and quickly achieve batch forming of workpieces.

[0003] Existing punch presses have certain drawbacks during use. When metal sheets are punched on the work platform of the punch press, the sheets are in an open loading and unloading state. Therefore, each time the sheet is punched, it is necessary to rely on manual labor or clamps to clamp the sheet. However, the frequency of sheet clamping and delivery cannot be coordinated with the regular lifting and lowering of the punch to achieve linkage.

[0004] In view of this, a quick clamping mechanism for metal punching machines was designed to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows: A quick clamping mechanism for a metal punch press includes a punch press bottom die assembly and a punch top die, a horizontally positioned metal plate disposed within the punch press bottom die assembly, and a stabilizing and material-retrieving mechanism mounted on the punch top die. The punch press bottom die assembly includes a base, a pad on the top of the base, a shaft installed within the pad, a pusher plate movably mounted on the shaft, two traction rods movably mounted within the pad, reinforcing springs on the traction rods, and the outer ends of the traction rods movably mounted on a clamping seat inside the pusher plate. The stabilizing and material-retrieving mechanism includes two clamps mounted on the punch top die, two load-bearing frames mounted outside the two clamps, a support plate installed within the load-bearing frame, two load-bearing rollers movably mounted within the support plate, and two symmetrically distributed pressure-stabilizing rollers movably mounted within the two load-bearing frames.

[0007] In a preferred embodiment, the present invention can be further configured such that: two vertical holes are provided inside the pad, and bolts are inserted into the vertical holes, the bolts being threaded into the base.

[0008] In a preferred embodiment, the present invention can be further configured such that: the upper surface of the top section of the pusher plate is provided with a pad to increase frictional resistance.

[0009] In a preferred embodiment, the present invention can be further configured such that: the inside of the load-bearing frame is provided with a sliding groove, and the two ends of the pressure stabilizing roller respectively penetrate into the sliding grooves of the two load-bearing frames.

[0010] In a preferred embodiment, the present invention can be further configured as follows: both ends of the pressure stabilizing roller are equipped with clamps, a rod sleeve is installed on the rod segment at the top of the clamp, a force arm is installed on the outside of the rod sleeve, a guide rod is inserted into the force arm and the guide rod is movably installed in the load-bearing frame, a support rod is movably installed on the other end of the force arm, a column leg is fixedly installed at the bottom of the support rod, and a reset spring is provided on the outside of the support rod.

[0011] In a preferred embodiment, the present invention can be further configured such that: an elliptical slot is provided in the end of the lever arm that bears pressure on the top of the reset spring, and the support rod extends through to the center of the elliptical slot.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. This utility model installs a stabilizing material feeding mechanism on the punch die of an existing punch press. As the punch die rises and falls rhythmically towards the base, the stabilizing material feeding mechanism, which moves in sync with the punch die, pre-presses and delivers the horizontally placed metal plate.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0016] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0017] The following describes, with reference to the accompanying drawings, some embodiments of a metal punching machine quick clamping mechanism provided by this utility model.

[0018] Example 1: Combination Figures 1 to 5 As shown, the present invention provides a quick clamping mechanism for a metal punching press, including a punching press bottom die assembly 100 and a punch top die 200, a horizontally placed metal plate 300 disposed within the punching press bottom die assembly 100, and a stabilizing and material-retrieving mechanism 400 mounted on the punch top die 200. When the punch top die 200 is pushed, it will drive the stabilizing and material-retrieving mechanism 400 to rise and fall synchronously, and punch the horizontally placed metal plate 300. The punching press bottom die assembly 100 is used to provide effective stabilizing support for the punched part of the metal plate 300.

[0019] The punch press bottom die assembly 100 includes a base 110, a pad 120 is provided on the top of the base 110, a shaft 1202 is installed inside the pad 120, a pusher plate 130 is movably installed on the shaft 1202, two traction rods 140 are movably installed inside the pad 120, a reinforcing spring 150 is provided on the traction rod 140, and the outer end of the traction rod 140 is movably installed on the clamp on the inner side of the pusher plate 130. The pad 120 has two vertical holes, and bolts 1201 are inserted into the vertical holes. Bolts 1201 are threaded into the base 110. The upper surface of the top plate section of the pusher plate 130 is provided with a pad to increase frictional resistance. The material stabilization and feeding mechanism 400 includes two clamps 440 mounted on the punch top die 200, and two load-bearing frames 410 are mounted outside the two clamps 440. A support plate 420 is installed inside the support frame 410, and two load-bearing rollers 430 are movably installed inside the support plate 420. Two symmetrically distributed pressure-stabilizing rollers 450 are movably installed inside the two support frames 410.

[0020] When in use, the rising punch die 200 will drive the stabilizing material feeding mechanism 400 to rise synchronously, and the metal plate 300 supported by the stabilizing material feeding mechanism 400 will open the maximum gap with the upper surface of the base 110. At this time, the two traction rods 140 will be pressed by the two reinforcing springs 150 and move towards the top mold of the base 110. The retracted two traction rods 140 will pull the push plate 130 to flip upward along the axis of the shaft 1202. When the punch die 200 descends and drives the stabilizing feeding mechanism 400 to descend simultaneously, the part of the metal plate 300 to be punched will be effectively supported by the top mold of the base 110. After the punch die 200 continues to descend, the punch die 200 will work with the base 110 to quickly punch the part of the metal plate 300 that is clamped. The pusher plate 130 will extend outward under the pressure of the metal plate 300. After the metal plate 300 is punched, the rising metal plate 300 will lose the pressure on the pusher plate 130, and the pulled pusher plate 130 will push the metal plate 300 to move laterally outward, ensuring that the metal plate 300 can be fed synchronously with the punch die 200 punching operation.

[0021] Example 2: Combination Figure 4 and Figure 5 As shown, in the above embodiment, the inside of the load-bearing frame 410 is provided with a sliding groove, and the two ends of the pressure stabilizing roller 450 respectively pass through the sliding grooves of the two load-bearing frames 410. Both ends of the pressure stabilizing roller 450 are equipped with clamps 460. A rod sleeve 4601 is installed on the rod section at the top of the clamp 460. A lever arm 470 is installed on the outside of the rod sleeve 4601. A guide rod 4701 is inserted into the lever arm 470 and is movably installed in the load-bearing frame 410. A support rod 480 is movably installed on the other end of the lever arm 470. A column leg 4801 is fixedly installed at the bottom of the support rod 480. A reset spring 490 is provided on the outside of the support rod 480. The lever arm 470 is supported by an elliptical slot at the top end of the reset spring 490, and the support rod 480 extends through to the center of the elliptical slot.

[0022] Preferably, the bottom end of the column leg 4801 is fixedly installed with an anti-slip pad. When the punch die 200 descends, the four column legs 4801 will bear pressure on the top of the base 110. After the column legs 4801 and the return spring 490 exert upward and reverse pressure, the lever arm 470 will drive the sleeve 4601 and the chuck 460 to rise. The two pressure rollers 450 can then work with the four pressure rollers 450 to relatively press the horizontally placed metal plate 300. The punch die 200, which continues to descend, will effectively punch the pressed metal plate 300.

[0023] The working principle and usage process of this utility model are as follows: Before use, two clamps 440 are fixed to the outside of the rod of the punch top die 200. As the punch top die 200 rises, it drives the two clamps 440 to rise. The two load-bearing frames 410 will be pulled to maintain the maximum gap with the upper surface of the base 110. Then, the metal plate 300 is placed along the top of the four load-bearing rollers 430 until the metal plate 300 is inserted horizontally into the gap of the two pressure stabilizing rollers 450. As the punch die 200 is hydraulically driven and descends, until the die head at the bottom of the punch die 200 presses against the top of the metal plate 300 and works with the base 110 to achieve rapid punching, during the punching process, the four evenly distributed column legs 4801 and the support rod 480 will push the four lever arms 470 in the opposite direction, and the lever arms 470 will rotate around the guide rod 4701 as the axis. Finally, the chuck 460 will push the pressure roller 450 down. At this time, the part of the metal plate 300 that is bidirectionally clamped by the two pressure rollers 450 and the four load-bearing rollers 430 will be effectively stabilized and clamped, and the bottom die head of the punch die 200 can avoid the plate being pressured and shifting during the punching of the metal plate 300. After punching is completed, the pusher plate 130, which is squeezed by the metal plate 300 and the punch die 200, will be quickly reset and retracted by the lateral traction of two reinforcing springs 150 and two traction rods 140. Finally, the metal plate 300, which is lifted upward, will be pushed outward by the retracted pusher plate 130. This mechanism can ensure that the punch die 200 rises and falls regularly, while also effectively feeding and pushing the metal plate 300.

[0024] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
