Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically to a waste discharge device for stamping equipment. Background Technology

[0002] In the automated production of molds, a prominent technical challenge is that, due to their structural limitations, some molds cause waste material generated during the trimming process to slide directly and accumulate on the worktable of the stamping equipment. Furthermore, in modern fully enclosed automated production lines, the stamping equipment is completely isolated from the operating area through physical isolation devices. This necessitates a complete shutdown of the entire line for waste removal, severely restricting production continuity and causing significant capacity losses.

[0003] Currently, several automation solutions attempted in the industry to address this problem have significant limitations. For example, using conveyor belts for waste transport requires a complete drive and transmission system, whose inherent structure occupies limited and valuable space on the workbench. Furthermore, conveyor belts typically require fixed installation; if they are disassembled for each mold change, reinstallation necessitates tedious and precise resetting adjustments, otherwise, the alignment accuracy with the waste material landing point will be affected. This process is cumbersome, inefficient, and cannot meet the demands of high-efficiency production. Additionally, using industrial robots for gripping is also unsuitable. To achieve precise gripping, the robot requires a high-precision vision recognition system and a dedicated end effector, leading to an exceptionally complex system and a sharp increase in cost. Moreover, its operating cycle time may be difficult to match with high-speed stamping equipment, limiting its application in certain high-efficiency production scenarios.

[0004] To address the problems mentioned above in the background art, this utility model provides a waste discharge device for stamping equipment. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned defects or problems in the background technology and provide a waste discharge device for stamping equipment. The device has a compact structure and effectively solves the problem of waste accumulation on the workbench in a fully enclosed stamping production line without encroaching on the effective space of the workbench or sacrificing production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A waste discharge device for stamping equipment is installed on the worktable of the stamping equipment to push the waste discharged from the mold away from the worktable. The device includes: a fixed base, a waste slide plate, a drive mechanism, a sliding mechanism and a waste push plate.

[0008] A fixed base is mounted on the workbench via a quick-connect mechanism, and the drive mechanism, sliding mechanism and waste push plate are all mounted on the fixed base;

[0009] A waste material slide plate is provided on the side of the fixed base near the mold to receive waste material that slides off the mold;

[0010] A drive mechanism is mounted on the fixed base, and the movement of the drive mechanism is controlled by a stamping device;

[0011] A sliding mechanism includes a slide block and a guide rail; the guide rail is mounted on the fixed base; the slide block is slidably disposed on the guide rail;

[0012] A waste pusher plate, one end of which is fixed to the slide block and extends above the waste slide plate;

[0013] The power output end of the drive mechanism is connected to the slide block to drive the slide block and the waste push plate to reciprocate along the guide rail, thereby pushing the waste falling on the waste slide block away.

[0014] Furthermore, the driving mechanism is configured as a cylinder, with its cylinder body fixedly mounted on the fixed base; the air passage interfaces on both sides of the cylinder are respectively connected to the air source of the stamping equipment through air pipes, and the switching of the cylinder's air intake and exhaust is controlled by the stamping equipment, so that the cylinder's pushing action is synchronized with the stamping stage of the mold, and the resetting action is synchronized with the mold's return stage.

[0015] Furthermore, a drive block is fixedly connected to the power output end of the cylinder, and a slot is formed on the drive block, and the slide is accommodated in the slot; when the drive block reciprocates, the inner drive surface of the slot pushes the slide to move synchronously.

[0016] Furthermore, the quick-connect mechanism includes a U-shaped groove disposed on one side of the fixed base and at least one T-bolt that mates with the U-shaped groove.

[0017] Furthermore, the adjacent sides of the waste material slide plate and the fixed base are quickly positioned and fitted through mortise and tenon structures or positioning pins.

[0018] Furthermore, the surface of the waste material slide plate is provided with a wear-resistant coating or has wear-resistant pads attached.

[0019] Furthermore, a gap is left between the bottom surface of the waste pusher plate and the upper surface of the waste slide plate to prevent the waste pusher plate from directly rubbing against the waste slide plate.

[0020] Furthermore, it also includes limiting posts, which are disposed at both ends of the guide rail of the sliding mechanism to limit the movement stroke of the slide block and the waste push plate.

[0021] Furthermore, the limiting post is an adjustable limiting post, which is installed on the fixed base by means of a threaded connection to adapt to different waste material pushing strokes.

[0022] Furthermore, it also includes at least one waste collection box, which is disposed outside the discharge end of the waste slide plate and is used to receive waste pushed off the waste slide plate.

[0023] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects;

[0024] (1) This utility model provides a waste discharge device for stamping equipment. The device has a compact structure and effectively solves the problem of waste accumulation on the workbench in a fully enclosed stamping production line without encroaching on the effective space of the workbench or sacrificing production efficiency. The present invention uses a drive mechanism to control the stamping equipment in conjunction with the stamping equipment, so that the pushing action of the waste pusher plate is synchronized with the stamping stage of the mold, and the resetting action is synchronized with the return stroke of the mold. This realizes automated waste cleaning in conjunction with the stamping cycle, effectively solving the problem of having to stop the machine for cleaning due to waste accumulation in the existing fully enclosed automated production line, ensuring the continuity and efficiency of production. In addition, the entire device is integrated on a fixed base and can be quickly installed or disassembled on the workbench through a quick connection mechanism without complex modification of the equipment. This minimizes the encroachment on the effective space of the workbench and shows significant advantages over traditional conveying devices in space-constrained working conditions.

[0025] (2) The fixed base of this utility model can be quickly disassembled and assembled. The waste slide can be quickly positioned by mortise and tenon structure or positioning pin, so that the device can be flexibly adjusted or moved out as the mold is changed. This avoids the problem of repeated adjustment and alignment when changing the mold of the traditional fixed material discharge device, and ensures the smooth connection and efficient flow of the production process of multi-specification products.

[0026] (3) This utility model uses a cylinder as the drive, which provides a stable power source and is easy to control. The sliding mechanism works in conjunction with the guide rail, ensuring smooth and precise movement. The waste slide plate is equipped with a wear-resistant layer, and a gap is left between the waste push plate and the waste slide plate to prevent direct friction between the two, effectively reducing operational wear, thereby extending the service life of the device and reducing maintenance frequency and costs.

[0040] See Figure 1-6 This embodiment provides a waste discharge device for a stamping equipment. The device is installed on the worktable 1 of the stamping equipment and is used to push the waste 11 discharged from the mold 10 away from the worktable surface to prevent the waste 11 from accumulating.

[0041] The device mainly includes: a fixed base 2, a waste slide plate 3, a drive mechanism 4, a sliding mechanism 5, a waste push plate 6, and a waste collection box 9;

[0042] The fixed base 2 serves as the mounting foundation for the entire device and is mounted on the workbench 1 via a quick-connect mechanism 7. In this embodiment, the quick-connect mechanism 7 is preferably a U-shaped groove 71 located on one side of the fixed base 2 and a T-bolt 72 that mates with the U-shaped groove 71. The T-bolt 72 enables quick locking between the fixed base 2 and the workbench 1. During disassembly, the entire device can be removed simply by loosening the bolt. This design facilitates mold 10 replacement and equipment maintenance.

[0043] The drive mechanism 4, sliding mechanism 5 and waste push plate 6 are all integrated and installed on the fixed base 2, forming a compact functional module.

[0044] The drive mechanism 4 is preferably a cylinder 41. In this embodiment, its cylinder body is fixedly installed on the fixed base 2 by bolts. The air passage interfaces on both sides of the cylinder 41 are connected to the air source of the stamping equipment through air pipes. The stamping equipment controls the switching of air intake and exhaust of the cylinder 41, so that the pushing action of the cylinder 41 is synchronized with the stamping stage of the mold 10, and the resetting action is synchronized with the return stage of the mold 10, realizing automated linkage.

[0045] The sliding mechanism 5 includes a slide block 52 and a guide rail 51; the guide rail 51 is mounted on the fixed base 2; the slide block 52 is slidably disposed on the guide rail 51. In this embodiment, to optimize transmission, a drive block 42 is fixedly connected to the power output end of the cylinder 41. A slot 421 is formed on the drive block 42, and the slide block 52 is accommodated in the slot 421. When the cylinder 41 is actuated, the drive block 42 reciprocates linearly and pushes the slide block 52 to move synchronously along the guide rail 51 smoothly and reliably through the inner driving surface of the slot 421.

[0046] One end of the waste pusher plate 6 is fixed to the slide block 52 by bolts, and its main body extends and is suspended above the waste slide plate 3. The waste slide plate 3 is located on the side of the fixed base 2 near the mold 10 and is used to receive the waste 11 sliding off the mold 10. The adjacent side of the waste slide plate 3 and the fixed base 2 are quickly positioned and reliably fitted by tenon and mortise structures or positioning pins to ensure installation accuracy and convenience. To further improve durability, in this embodiment, the surface of the waste slide plate 3 is provided with a wear-resistant coating or has wear-resistant pads attached to resist the erosion and wear of the waste 11.

[0047] To prevent motion interference and abnormal wear, in this embodiment, an appropriate gap is left between the bottom surface of the waste push plate 6 and the upper surface of the waste slide plate 3. This design can effectively ensure that the push plate does not rub directly against the slide plate during high-speed reciprocating motion, ensuring smooth operation and extending the service life of key components.

[0048] Furthermore, to precisely control the waste pushing stroke and prevent overshoot, this embodiment provides limiting posts 8 at both ends of the guide rail 51 of the sliding mechanism 5 to mechanically limit the movement range of the slide block 52 and the waste push plate 6. Preferably, the limiting posts 8 are adjustable and are installed in the screw holes on the fixed base 2 via a threaded connection, so that the pushing distance can be flexibly adjusted according to the actual size of the waste.

[0049] On the outside of the discharge end of the waste slide plate 3, at least one waste collection box 9 is also provided to receive and store the pushed-down waste 11, thereby realizing the automatic collection and centralized cleaning of waste 11 and maintaining the cleanliness of the working environment.

[0050] Specific usage instructions;

[0051] (1) After placing the stamped parts into the cavity of the mold 10, start the stamping equipment; when the stamping equipment reaches the bottom dead center, the mold 10 closes, and the sheet metal is stamped and trimmed, generating new scrap 11; simultaneously, the stamping equipment introduces compressed air into the cylinder 41 from the air passage interface on one side of the cylinder 41, and connects the other side interface to the exhaust circuit. The output end of the cylinder 41 and the drive block 42 fixedly connected to the output end start to move under the drive of air pressure, and use the inner drive surface of the slot 421 on the drive block 42 to push the slide block 52 of the sliding mechanism 5. The slide block 52 then carries the scrap pusher 6 and moves forward at high speed and smoothly along the guide rail 51 with a preset stroke limited by the limit post 8; during this process, the scrap pusher 6 pushes all the scrap 11 that has accumulated on the scrap slide plate 3 when the mold 10 is opened once, sweeping it off the worktable and causing it to fall into the scrap collection box 9.

[0052] (2) After the stamping is completed, the stamping equipment moves up to the top dead center and the mold 10 opens; the newly generated trimming waste 11 in this stamping process falls out of the mold 10, slides out along the slide on its side, and falls onto the waste slide plate 3 of the device; at the same time, the air source of the stamping equipment is reversed, and compressed air enters the cylinder 41 from the air passage interface on the other side of the cylinder 41. The output end of the cylinder 41 drives the waste push plate 6 to retract along the guide rail 51 to the initial position, in preparation for the next material discharge action.

[0053] (3) The stamping equipment performs the next operation and moves down again; repeat the above steps (1) and (2) in this way, so that after each stamping and trimming is completed, the cylinder 41 drives the waste push plate 6 to complete a discharge action, automatically cleaning up the waste 11 generated in the previous cycle.

[0054] This utility model provides a waste discharge device for stamping equipment. This device features a compact structure and effectively solves the problem of waste accumulation on the worktable in fully enclosed stamping production lines without encroaching on the effective space of the worktable or sacrificing production efficiency. Through linkage control between the drive mechanism and the stamping equipment, this invention synchronizes the pushing action of the waste pusher plate with the stamping stage of the die, and the resetting action with the return stroke of the die. This achieves automated waste cleaning linked to the stamping cycle, effectively solving the problem of having to stop for cleaning due to waste accumulation in existing fully enclosed automated production lines. This ensures the continuity and efficiency of production. Furthermore, the entire device is integrated into… The device can be quickly installed or removed from the workbench via a quick-connect mechanism on the fixed base, without requiring complex modifications to the equipment. This minimizes the encroachment on the effective space of the workbench and demonstrates a significant advantage over traditional conveying devices in space-constrained conditions. Furthermore, the fixed base serves as the installation foundation for the entire device and allows for quick assembly and disassembly. The waste slide plate can be quickly positioned using mortise and tenon joints or locating pins, enabling the device to be flexibly adjusted or moved when changing molds. This avoids the problem of repeated alignment adjustments required when changing molds with traditional fixed discharge devices, ensuring smooth connection and efficient flow in the production process of multiple product specifications.

[0055] The description of the above specification and embodiments is used to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model.
