Description

Technical Field

[0001] This invention relates to the field of machining tooling technology, and in particular to a pneumatic stamping tooling. Background Technology

[0002] In many industrial fields such as mechanical assembly, automotive parts manufacturing, home appliance production, and electronic equipment assembly, thin plate parts such as guide plate gaskets, sealing gaskets, and adjusting gaskets are indispensable basic accessories. The main function of solid round gaskets is to fill the small gaps between parts or adjust the installation height as flat blocks to achieve local flatness; they can also be used as simple sealing or plugging elements.

[0003] Currently, for the processing of such thin gasket-type parts, the industry mainly uses small benchtop punch presses with simple molds for stamping. Although this method can improve processing accuracy and efficiency to a certain extent, such equipment is usually a single-station processing mode, requiring operators to perform loading, positioning, stamping, and unloading operations on each part. It cannot achieve continuous processing of multiple parts and multiple stations, and frequent manual intervention is still required during batch production, resulting in limited efficiency improvement.

[0004] To improve processing speed, existing automatic gasket punching machines use multiple punches arranged side by side to punch a row of gaskets at once after flattening the steel coil, thus producing multiple gaskets in one punching and improving processing speed. However, for multiple small, discontinuous pieces, manual handling is still required to place them on the punching table for processing, resulting in low automation. Summary of the Invention

[0005] To address the aforementioned shortcomings, this invention provides a pneumatic stamping fixture to solve the problem that existing thin-plate gasket-type parts cannot achieve multi-batch continuous automated processing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pneumatic stamping fixture, comprising a processing table, a first side plate fixedly connected to the upper surface of the processing table, a cylinder fixedly mounted on the first side plate, the telescopic end of the cylinder slidingly penetrating the first side plate and fixedly connected to a punch, a slide rail fixedly connected to the upper surface of the processing table, a T-shaped plate slidably connected to the slide rail, a material storage mechanism disposed above the T-shaped plate, the material storage mechanism comprising a frame fixedly connected to the upper surface of the T-shaped plate, a plurality of partitions fixedly connected inside the frame, a second side plate fixedly fixed to the frame, the second side plate being fixed between the partitions and the frame and between two adjacent partitions, the second side plate, the partitions and the frame forming a cavity for storing thin sheet parts, a clamping plate slidably connected inside the cavity, the clamping plate being able to cooperate with the second side plate to clamp the thin sheet parts.

[0007] Preferably, a connecting rod is fixedly connected to the side of the clamp away from the second side plate, the other end of the connecting rod slides through the frame and is fixedly connected to a first pull plate, a first spring is fixedly connected to the outer surface of the first pull plate, and the other end of the first spring is fixedly connected to the frame.

[0008] Preferably, a movable plate is slidably connected to the upper surface of the processing table, the movable plate is fixedly connected to the punch, and a linkage mechanism is provided between the movable plate and the material storage mechanism. The linkage mechanism is used to drive the material storage mechanism to move along the slide rail to switch work stations when the movable plate returns.

[0009] Preferably, the linkage mechanism includes a vertical plate fixedly connected to the upper surface of the processing table, a first rotating shaft rotatably mounted inside the vertical plate, a one-way bearing fixedly mounted on the outer surface of the first rotating shaft, a first gear fixedly mounted on the outer ring of the one-way bearing, and a first toothed plate fixedly connected to the bottom surface of the frame, wherein the first toothed plate meshes with the first gear.

[0010] Preferably, a second rotating shaft is rotatably mounted inside the processing table, and the second rotating shaft and the first rotating shaft are connected by a bevel gear set.

[0011] Preferably, a second toothed plate is fixedly connected to the side of the movable plate away from the first side plate, and a second gear is fixedly connected to the outer surface of the second rotating shaft, and the second gear can mesh with the second toothed plate.

[0012] Preferably, a support plate is fixedly connected to the upper surface of the processing table, and a second wedge plate is fixedly connected to the upper surface of the support plate. Each first pull plate is fixedly connected to a first wedge plate that matches the second wedge plate on the side near the frame.

[0013] Preferably, a guide shaft is fixedly connected to the bottom surface of the processing table, a second pull plate is slidably connected to the outer surface of the guide shaft, a lifting plate is fixedly connected to the upper surface of the second pull plate, the other side of the lifting plate slides through the processing table and extends to the top of the processing table, and multiple one-way guide wheels are rotatably installed on the lifting plate, and the one-way guide wheels are in contact with the bottom surface of the frame.

[0014] Preferably, a circular plate is fixedly connected to one end of the guide shaft away from the processing table, a second spring is fixedly connected to the upper surface of the circular plate, and the other end of the second spring is fixedly connected to the bottom surface of the second pull plate.

[0015] The beneficial effects of this invention are: ① This invention uses a cylinder to drive the punch to complete the stamping action. With the help of a multi-chamber material storage mechanism, multiple batches of thin plate parts can be clamped at one time. A single stamping action can complete the synchronous stamping processing of all parts in a single chamber. At the same time, the linkage mechanism realizes automatic station switching during the stamping return process. There is no need for manual stopping to change materials or alignment. The entire process only requires one clamping to complete the continuous stamping operation of multiple batches of parts, which completely solves the problem of low efficiency caused by single-piece processing and repeated manual operation in the prior art.

[0016] ② The present invention, through the cooperation between the first wedge plate and the second wedge plate, can automatically release the fixation of the thin plate parts when switching stations during the stamping return process. Through the cooperation between the guide shaft, the second pull plate, the round plate, the second spring, the lifting plate and the one-way guide wheel, the material storage mechanism can be tightened and limited without affecting the reset of the material storage mechanism, thereby improving the stability of the material storage mechanism during movement and processing.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific examples described herein are merely illustrative and not intended to limit the invention. The directional terms used in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the invention. Furthermore, in all embodiments, the same reference numerals denote the same elements.

[0020] like Figures 1-7 As shown, a pneumatic stamping fixture includes a processing table 1. Multiple bases with threaded holes are fixed below the processing table 1, and the processing table 1 is fixed in place by the bases and bolts to prevent displacement. The upper surface of the processing table 1 is flat. The processing table 1 is fixedly connected to a first side plate 2, which is perpendicular to the upper surface of the processing table 1. A cylinder 4 is fixedly installed on the outer wall of the first side plate 2. The telescopic end of the cylinder 4 extends horizontally and slides through the first side plate 2. A through hole is provided on the first side plate 2 for the telescopic end to pass through. A punch 6 is fixedly connected to the end of the telescopic end, and the punch 6 reciprocates linearly with the telescopic end.

[0021] On the upper surface of the processing table 1, a slide rail 7 is fixedly installed horizontally. A T-shaped plate 8 is slidably fitted on the slide rail 7, and the bottom shape of the T-shaped plate 8 matches the slide rail 7, so that the T-shaped plate 8 can move smoothly along the slide rail 7. A material storage mechanism is provided above the T-shaped plate 8 for storing and positioning the thin sheet parts to be stamped.

[0022] Specifically, the storage mechanism includes a frame 9 fixedly connected to the upper surface of the T-shaped plate 8. The frame 9 is an upward-opening rectangular frame structure. Multiple parallel and equally spaced partitions 3 are fixedly connected inside the frame 9, with the partitions 3 perpendicular to one pair of side walls of the frame 9. A second side plate 14 is also fixed to the frame 9. That is, a second side plate 14 is fixed in each independent space enclosed by the partition 3 and the side wall of the frame 9, or in the space between two adjacent partitions 3. In this way, the second side plate 14, the partitions 3, and the side wall of the frame 9 together form several independent chambers for storing thin sheet metal parts. The shape of each chamber is adapted to the shape of the thin sheet metal part to be stored, typically in the form of a flat cuboid.

[0023] Inside each chamber, a clamping plate 10 is slidably installed. This clamping plate 10 can be moved toward the second side plate 14 by manual adjustment or by tightening with an elastic element, thereby cooperating with the second side plate 14 to clamp the thin sheet part located between them. For example, an adjusting screw can be connected to the side of the clamping plate 10 away from the second side plate 14. The screw passes through the side wall of the frame 9 and is screwed with a locking nut. By rotating the screw, the clamping plate 10 can be moved and locked in position, thereby accommodating thin sheet parts of different thicknesses and achieving reliable clamping.

[0024] Alternatively, an elastic element clamping method can be used, with one end of a connecting rod 11 fixed on the clamping plate 10. The other end of the connecting rod 11 extends horizontally and slides through the corresponding side wall of the frame 9, meaning that a through hole is provided on the side wall of the frame 9 for the connecting rod 11 to pass through. A first pull plate 12 is fixedly connected to one end of the connecting rod 11 that protrudes from the frame 9. The first pull plate 12 is plate-shaped and fixed perpendicularly to the connecting rod 11.

[0025] One end of a first spring 13 is fixedly connected to the side wall of the first pull plate 12. The other end of the first spring 13 is fixedly connected to the outer side wall of the frame 9. The first spring 13 is sleeved on the outside of the connecting rod 11. When the first spring 13 is in its natural state, it pulls the first pull plate 12 closer to the frame 9, thereby driving the clamping plate 10 to move towards the second side plate 14 through the connecting rod 11, so that a clamping force is formed between the clamping plate 10 and the second side plate 14. When it is necessary to insert or remove a thin plate part, the operator pulls the first pull plate 12 away from the frame 9 by hand, overcoming the elastic force of the first spring 13, so that the connecting rod 11 drives the clamping plate 10 to move away from the second side plate 14, thereby releasing the part. After releasing the first pull plate 12, the restoring force of the first spring 13 causes the clamping plate 10 to re-clamp the part, thereby adapting to thin plate parts of different thicknesses and achieving reliable clamping. The first pull plate 12 and the clamping plate 10 are both provided with through holes for the punch 6 to pass through, so as to avoid interference with the feeding action of the punch 6. Similarly, the second side plate 14 is also provided with through holes, and the processed gasket can be discharged through the through holes.

[0026] After placing multiple sheet metal parts to be stamped into their respective chambers, the operator pushes the T-shaped plate 8 or frame 9 along the slide rail 7, aligning the chambers containing the parts sequentially with the punch 6. The cylinder 4 is activated, its telescopic end rapidly extending the punch 6 to stamp the parts in the chambers. After stamping is complete, the cylinder 4 resets, and the operator pushes the T-shaped plate 8 or frame 9 again, allowing the parts from the next chamber to enter the stamping station.

[0027] As a further explanation of this embodiment, a movable plate 5 is slidably connected to the upper surface of the processing table 1. Specifically, a slider may be provided on the bottom surface of the movable plate 5, which slides in cooperation with a linear guide rail fixed to the upper surface of the processing table 1. The movable plate 5 is fixedly connected to the punch 6, so that the two can move together.

[0028] A linkage mechanism is installed between the moving plate 5 and the storage mechanism. The function of this linkage mechanism is as follows: when the cylinder 4 drives the moving plate 5 to return, the linkage mechanism can automatically drive the storage mechanism to move one station along the slide rail 7, so that the thin plate part in the next chamber is aligned with the punch 6, thereby realizing continuous automatic stamping. When the moving plate 5 moves forward, the linkage mechanism does not drive the storage mechanism to ensure that the position of the part is fixed during the stamping process.

[0029] As a further explanation of this embodiment, the linkage mechanism includes a vertical plate 18 fixedly connected to the upper surface of the processing table 1. A first rotating shaft 19 is rotatably mounted inside the vertical plate 18. A one-way bearing 20 is fixedly mounted on the outer surface of the first rotating shaft 19. A first gear 21 is fixedly mounted on the outer ring of the one-way bearing 20. A first toothed plate 22 is fixedly connected to the bottom surface of the frame 9, and the first toothed plate 22 meshes with the first gear 21. The inner ring of the one-way bearing 20 is fixedly connected to the first rotating shaft 19. The outer ring can achieve one-way free rotation and reverse locking transmission relative to the inner ring. When the first gear 21 rotates in the locking direction of the one-way bearing 20, it can drive the first toothed plate 22 to move laterally through meshing transmission, thereby driving the material storage mechanism to slide as a whole to achieve automatic switching of the work position. When the first gear 21 rotates in the free rotation direction of the one-way bearing 20, it will not drive the first rotating shaft 19 to rotate synchronously, thereby not driving the material storage mechanism to move, avoiding work position deviation during the stamping feed process, and ensuring the accuracy of the stamping position.

[0030] The processing table 1 has a second rotating shaft 31 rotatably mounted inside. The second rotating shaft 31 and the first rotating shaft 19 are connected by a bevel gear set. The bevel gear set includes two meshing bevel gears, which are fixedly installed at the ends of the first rotating shaft 19 and the second rotating shaft 31, respectively. This enables the reversal of the rotational motion, converting the rotational motion of the first rotating shaft 19 into the rotational motion of the second rotating shaft 31. This ensures that the transmission direction matches the motion direction of the workstation switching. At the same time, through the transmission ratio design of the bevel gear set, the movement distance of the material storage mechanism in a single workstation switching can be precisely controlled, ensuring that after each switching, the next chamber can be precisely coaxially aligned with the punch 6, ensuring the consistency of the stamping position.

[0031] A second toothed plate 24 is fixedly connected to the side of the movable plate 5 away from the first side plate 2. A second gear 23 is fixedly connected to the outer surface of the second rotating shaft 31, and the second gear 23 can mesh with the second toothed plate 24. The second toothed plate 24 moves linearly reciprocating synchronously with the movable plate 5. Through the meshing transmission with the second gear 23, the linear reciprocating motion of the movable plate 5 can be converted into the rotational motion of the second gear 23 and the first rotating shaft 19, providing power input for the linkage mechanism. In order to avoid the material storage mechanism moving too early during the return stroke of the movable plate 5, which would cause the punch 6 to interfere with the parts in the cavity or the clamping plate 10, a blank stroke is set at the starting position of the meshing of the second toothed plate 24 and the second gear 23. When the moving plate 5 performs the stamping feed motion, the second gear plate 24 drives the second gear 23 to rotate with the first rotating shaft 19. At this time, the rotation direction is consistent with the free rotation direction of the one-way bearing 20. The inner ring of the one-way bearing 20 rotates freely, and the material storage mechanism remains stationary, ensuring the stability of the part position during the stamping process. When the moving plate 5 performs the return motion, the second gear plate 24 moves to mesh with the second gear 23. The second gear plate 24 drives the second gear 23 to rotate in the opposite direction to the first rotating shaft 19. At this time, the rotation direction is consistent with the locking transmission direction of the one-way bearing 20. The first rotating shaft 19 drives the first gear 21 to rotate synchronously through the one-way bearing 20, thereby driving the material storage mechanism to complete the station switching, realizing the automatic linkage between the stamping return and station switching, without the need for additional drive components and manual control.

[0032] The T-shaped plate 8 has an elongated hole inside to allow the first rotating shaft 19 to pass, providing clearance for the installation and rotation of the first rotating shaft 19, and also providing travel clearance for the lateral movement of the material storage mechanism, ensuring that the operation of each component of the tooling is free from interference.

[0033] To enable automatic release of thin sheet parts after stamping for easy removal by operators, this solution has been further improved. Specifically, a support plate 16 is fixedly connected to the upper surface of the processing table 1, and a second wedge plate 17 is fixedly connected to the upper surface of the support plate 16. Each first pull plate 12 has a first wedge plate 15 that matches the second wedge plate 17 fixedly connected to its side near the frame 9. The inclined angles of the first wedge plate 15 and the second wedge plate 17 are the same, which can realize inclined surface pressing transmission. When the storage mechanism moves to switch positions, after the corresponding first wedge plate 15 and second wedge plate 17 come into contact, the second wedge plate 17 will press the first wedge plate 15 through the inclined surface, driving the first pull plate 12 to move outward, releasing the clamping of the part, and at the same time stretching the first spring 13 to store elastic potential energy.

[0034] Since the first gear 21 is engaged with the one-way bearing 20, the meshing of the first gear 21 and the first toothed plate 22 cannot provide locking force when the frame 9 moves in the opposite direction. Therefore, an additional locking mechanism is needed to prevent the frame 9 from moving in the opposite direction due to accident. Specifically, a guide shaft 25 is fixedly connected to the bottom surface of the processing table 1, and a second pull plate 26 is slidably connected to the outer surface of the guide shaft 25. The second pull plate 26 is located below the processing table 1, and a lifting plate 29 is fixedly connected to the upper surface of the second pull plate 26. The other side of the lifting plate 29 slides through the processing table 1 and extends above the processing table 1. Multiple one-way guide wheels 30 are rotatably installed on the lifting plate 29, and the one-way guide wheels 30 are in contact with the bottom surface of the frame 9. The lifting plate 29 moves up and down synchronously with the second pull plate 26. The one-way guide wheels 30 can only rotate freely in the direction of the material storage mechanism's workstation switching and lock in the opposite direction of the workstation switching. Due to the one-way characteristic of the one-way guide wheels 30, when the frame 9 moves in the opposite direction due to an accident, the one-way guide wheels 30 will lock or generate greater resistance, thereby preventing the material storage mechanism from moving in the opposite direction and ensuring the one-wayness and reliability of the workstation switching. When the material storage mechanism automatically switches stations, the one-way guide wheel 30 is in a free state, which can provide support and auxiliary guidance for the bottom surface of the frame 9, further improving the positioning accuracy of the station. After a batch of parts is processed, the second pull plate 26 is pulled down, which can drive the one-way guide wheel 30 to move downward and disengage from the frame 9, releasing the locking limit. At this time, the frame 9 can be pulled back to the initial station to quickly complete the reset of the material storage mechanism, so as to process the next batch of parts.

[0035] As a further explanation of this embodiment, a circular plate 27 is fixedly connected to one end of the guide shaft 25 away from the processing table 1. A second spring 28 is fixedly connected to the upper surface of the circular plate 27, and the other end of the second spring 28 is fixedly connected to the bottom surface of the second pull plate 26. The circular plate 27 provides mounting support for the second spring 28 and limits the downward stroke of the second pull plate 26 to prevent it from slipping off the guide shaft 25. The second spring 28 is always in a compressed state, providing a continuous upward lifting force for the second pull plate 26 and the lifting plate 29. When the tooling is operating normally, the elastic force of the second spring 28 pushes the one-way guide wheel 30 to always be in close contact with the bottom surface of the frame 9, ensuring stable and effective support.

[0036] Working principle When in the initial working position, the operator pulls the first pull plate 12 corresponding to the clamping chamber outward. The first pull plate 12 drives the clamping plate 10 to move away from the second side plate 14 through the connecting rod 11. At the same time, the first spring 13 is stretched to expand the clamping space in the chamber. Then, multiple thin plate gasket parts to be processed are neatly stacked in the chamber. The first pull plate 12 is released. Under the action of the rebound pull of the first spring 13, the clamping plate 10 automatically resets and stably clamps the stacked parts between the clamping plate 10 and the second side plate 14. Following this operation method, the gasket parts to be processed are clamped in the remaining chambers of the frame 9 in sequence to complete the one-time clamping of multi-station parts.

[0037] The pneumatic control system is activated, and the telescopic end of the cylinder 4 is extended. The cylinder 4 pushes the moving plate 5 and the punch 6 to feed along the processing table 1 toward the storage mechanism. The punch 6 simultaneously completes the stamping process of all the gasket parts stacked in the first chamber.

[0038] During this feeding process, the second toothed plate 24 moves synchronously with the moving plate 5, and drives the second gear 23 to rotate with the first rotating shaft 19 through meshing transmission. At this time, the rotation direction of the first rotating shaft 19 is consistent with the free rotation direction of the one-way bearing 20. The inner ring of the one-way bearing 20 rotates freely with the first rotating shaft 19 and will not drive the first gear 21 of the outer ring to rotate. Therefore, the material storage mechanism always remains stationary, ensuring that the part position is stable and there is no displacement deviation during the stamping process, thus ensuring stamping accuracy.

[0039] After a single stamping is completed, the pneumatic control system controls the retraction end of cylinder 4 to retract. Cylinder 4 pulls the moving plate 5 to return to the direction away from the material storage mechanism, simultaneously driving the punch 6 and the second toothed plate 24 to reset. During this return process, the second toothed plate 24 moves in the opposite direction with the moving plate 5, driving the second gear 23 to rotate in the opposite direction to the first rotating shaft 19. At this time, the rotation direction of the first rotating shaft 19 is consistent with the locking transmission direction of the one-way bearing 20. The first rotating shaft 19 drives the first gear 21 to rotate synchronously through the one-way bearing 20. The first gear 21, through meshing with the first toothed plate 22, drives the frame 9 and the entire material storage mechanism to move along the slide rail 7 towards the second wedge plate 17, completing the feed action of the workstation switching.

[0040] During the movement of the storage mechanism, the first wedge plate 15 corresponding to the chamber that has been stamped moves synchronously with the frame 9. When the inclined surface of the first wedge plate 15 contacts the inclined surface of the second wedge plate 17, as the storage mechanism continues to move, the second wedge plate 17 squeezes the first wedge plate 15 through the inclined surface, causing the first pull plate 12 to move outward. The connecting rod 11 drives the clamping plate 10 to move synchronously, releasing the clamping of the part in the chamber. At the same time, the first spring 13 is stretched. When the moving plate 5 is fully reset with the cylinder 4, the storage mechanism moves to the position where the next chamber to be processed is coaxially aligned with the punch 6, completing one automatic station switch.

[0041] In this cycle, each extension and retraction of cylinder 4 completes the stamping process of one chamber part and the automatic switching of the next chamber station without manual intervention, realizing multi-station continuous stamping operation.

[0042] After all the gasket parts in all the chambers of the storage mechanism have been stamped, the operator can directly remove the finished parts from each chamber. Then, the operator pulls down the second pull plate 26, which slides downwards along the guide shaft 25, simultaneously moving the lifting plate 29 and the one-way guide wheel 30 downwards. This disengages the one-way guide wheel 30 from the bottom surface of the frame 9, releasing the clamping limit on the frame 9. Simultaneously, the second spring 28 is compressed. At this point, the operator can pull the frame 9 along the slide rail 7 in the reverse direction towards the initial position to its maximum stroke. During the reverse movement of the frame 9, the first... The toothed plate 22 drives the first gear 21 to rotate in the opposite direction. At this time, the rotation direction is the same as the free rotation direction of the one-way bearing 20. The first gear 21 rotates freely and will not drive the first rotating shaft 19 and the linkage mechanism to move, so as to realize the unobstructed and rapid reset of the material storage mechanism. After the material storage mechanism is reset, the second pull plate 26 is released. Under the rebound action of the second spring 28, the second pull plate 26, the lifting plate 29 and the one-way guide wheel 30 automatically reset upward. The one-way guide wheel 30 re-contacts the bottom surface of the frame 9 and restores the locking support state, so that the clamping and stamping of the next batch of parts can be carried out.
