Description

Technical Field

[0001] This invention relates to the field of punching and stamping technology, specifically to a rapid punching and stamping equipment for aluminum parts. Background Technology

[0002] High-speed punching and stamping equipment for aluminum parts, also known as stamping machines or hydraulic presses, is widely used in engineering design. It can perform functions such as cutting, punching, blanking, bending, and riveting. These machines can be divided into various types according to the power source, such as mechanical punching machines, hydraulic punching machines, pneumatic punching machines, and servo punching machines. They are widely used in many fields such as automobile manufacturing, home appliance manufacturing, aerospace, construction, electronics, and jewelry, providing multifunctional support for the forming and shaping of metal parts.

[0003] In the blanking process of punching and stamping equipment, "material blockage" is a common and serious problem. "Material blockage" refers to the situation where, during the die stamping process, due to insufficient blanking design and machining clearance, the scrap material becomes larger in size after blanking due to elastic deformation. This increases the friction between the scrap material and the die cavity wall, resulting in excessive support force. Consequently, the scrap material gets stuck inside the die cavity and cannot fall out. This situation leads to poor feeding, which at best affects the production capacity of the punching and stamping equipment, requiring staff to stop the machine to repair the die and re-set and adjust the die. At worst, it can break the cutting edge, damage the expensive die and the spindle of the punching and stamping equipment. Moreover, in the high-speed progressive die industry, the frequency of "material blockage" is very high, causing great trouble for designers and die repair personnel.

[0004] To address the aforementioned problems, existing technologies offer several solutions. For example, patent application number CN202322650361.8 provides a punching device for manufacturing advertising signs, comprising a lower template with a through-hole, a fixed bracket on the upper side of the lower template, a lifting drive device connected to the fixed bracket, a drive rod of the lifting drive device connected to the lifting bracket, an upper module connected to the upper module, a punching rod connected to the punching hole, the punching rod being coaxially arranged with the punching hole, an axially penetrating airflow channel in the middle of the punching rod, and an air guide hole connected to the airflow channel in the upper module, the air guide hole being connected to an air source. This invention provides an airflow channel in the middle of the punching rod, making it less likely for the punched waste to clump together, allowing the waste to pass more easily through the punching hole and preventing blockage. However, this design, by adding an air source and using airflow to impact the waste, increases the manufacturing and maintenance costs of the punching equipment. Furthermore, this design continues to operate even when the waste does not cause blockage, thus increasing the equipment's energy consumption. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid punching and stamping equipment for aluminum parts, in order to solve the problem that during the die stamping process, due to the blanking design and the small processing clearance, the scrap material becomes larger in size after blanking due to elastic deformation, which increases the friction between the scrap material and the die cavity wall, resulting in excessive support force and causing the scrap material to get stuck inside the die cavity and unable to fall out.

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

[0007] A rapid punching and stamping device for aluminum parts includes a housing, a die, and a punch. A power assembly is also provided on the housing. The punch is connected to the power assembly. The die is fixedly connected to the housing. A punching hole is formed on the die. A mounting base is also fixedly connected to the die. An expansion assembly with an expansion slider is provided inside the mounting base. An expansion groove is also formed on the die. The expansion slider is slidably connected inside the expansion groove. A pressing rod is also provided inside the mounting base. The pressing rod is slidably connected inside the punching hole. A transmission assembly is also provided inside the mounting base. When the pressing rod is subjected to pressure and slides, the transmission assembly drives the expansion slider to move away from the punching hole.

[0008] It's easy to understand that due to the punching design and excessively small processing clearance, the scrap material becomes larger after punching due to elastic deformation. This increases the friction between the scrap material and the punch hole wall, resulting in excessive support force. Consequently, the scrap material gets stuck inside the die and cannot fall out. Therefore, this design incorporates an expansion component and a transmission component inside the aluminum part rapid punching and stamping equipment. When the punch punches down on the aluminum part, the punched scrap material follows one end of the punch into the punch hole. If the scrap material gets stuck in the punch hole and cannot fall out, it will accumulate inside the punch hole during continuous punching. At this point, the scrap material inside the punch hole will squeeze the pressing rod, causing the pressing rod to move. The transmission... The component also drives the expansion slider inside the adjustment component to move. Since the expansion slider slides away from the punch hole, the diameter of the punch hole increases. At this time, the waste material accumulated inside the punch hole loses the support of the inner wall of the punch hole and falls off. Therefore, this design avoids the waste material clogging the punch hole. Furthermore, this design can drive the transmission component by squeezing the pressing rod with the waste material, thereby causing the pressing rod to move. Therefore, this design does not require the addition of an additional power component, saving on manufacturing and maintenance costs. Moreover, this design only starts to work when waste material accumulates, thus reducing the wear of the expansion component and the transmission component and improving the service life of the expansion component and the transmission component.

[0009] Preferably, the expansion assembly includes a control slider slidably connected inside the mounting base. The die cavity is also provided with a connecting groove that connects the interior of the mounting base to the expansion groove. A rectangular block is fixedly connected to one end of the control slider. A rectangular groove is provided on the expansion slider. The rectangular block passes through the connecting groove and is slidably connected inside the rectangular groove. An expansion spring is also provided inside the mounting base. One end of the expansion spring is fixedly connected to the rectangular block, and the other end is fixedly connected to the inner wall of the rectangular groove. One end of the expansion slider is also provided with an arc surface, the axis of which is consistent with the axis of the punching hole.

[0010] As is easily understood, when scrap accumulates inside the punching hole, it presses against the pressing rod, causing it to move. This, in turn, drives the control slider. A rectangular block at one end of the control slider moves along with it, compressing the expansion spring inside the rectangular groove and pushing the expansion slider further away from the punching hole. This increases the hole's diameter, causing the accumulated scrap to fall off due to the lack of support from the hole's inner wall. Therefore, this design prevents scrap from clogging the punching hole, thus avoiding malfunction of the rapid punching equipment for aluminum parts. Furthermore, the design incorporates an arc-shaped surface at one end of the expansion slider, with the arc matching the arc of the punching hole's inner wall. This reduces wear between the scrap and the expansion slider as it slides inside the punching hole, improving the lifespan of the expansion assembly.

[0011] Preferably, the transmission assembly includes a rack, which is fixedly connected to a pressing rod. A connecting rod is rotatably connected inside the mounting base. A gear is also provided inside the mounting base, with the rack fixedly connected to the connecting rod and meshing with the rack. Two gears are also provided inside the mounting base, both fixedly connected to the connecting rod and positioned on opposite sides of the gear. Two racks are also slidably connected inside the mounting base, meshing with the two gears and fixedly connected to a control slider. A return spring is also provided inside the mounting base, with one end fixedly connected to the control slider and the other end fixedly connected to the inner wall of the mounting base. The gear ratio between the first and second gears is 1:2.

[0012] As is easily understood, when scrap accumulates inside the punching hole, it presses against the pressing rod, causing it to move. As the pressing rod moves, rack 1, fixedly connected to it, moves along with it. This rack 1 pushes gear 1 to rotate, which in turn drives the connecting rod to rotate. The rotation of the connecting rod causes gear 2, fixedly connected to both ends, to rotate as well. At this point, rack 2 on both sides of gear 1 begins to move, pushing the control slider to compress the reset spring, thus driving the expansion assembly to work. This design is simple, compact, and easy to maintain. Furthermore, it utilizes the pressure exerted on the pressing rod by the accumulated scrap in the punching hole to drive the expansion assembly, eliminating the need for additional power components and saving on manufacturing and maintenance costs.

[0013] Preferably, the expansion slider has two limiting grooves, and the die is hinged with two limiting blocks. A torsion spring is provided at the hinge point between the limiting block and the die. The torsion spring pushes one end of the limiting block to rotate into the limiting groove. The plane of the limiting block near the punch hole is in contact with the inner wall of the limiting groove, and the plane of the other side of the limiting groove is in contact with the control slider. The expansion slider is provided with a limiting plane, and the limiting plane is in contact with the surface of the die.

[0014] It's easy to understand that when the punch is stamping, the punched hole is subjected to significant pressure. If the expanding slider is displaced due to equipment vibration or scrap material pressure during the punching process, the die on one side of the expanding groove will lose the support of the expanding slider. If this happens frequently, the die on the unsupported side will deform during long-term stamping, affecting stamping accuracy and accelerating wear between the punch and die. Therefore, this design uses a limiting block on the die. One side of the limiting block presses against the inner wall of the limiting groove, while the other side is held in place by the control slider. Regardless of vibration or pressure, the expanding slider will not displace. Even if the control slider is displaced due to vibration, as long as the pressing rod is not pressed into place, the plane on one side of the control slider will remain in contact with the limiting block. This design avoids the problem of the expanding slider being displaced due to vibration or scrap material pressure, causing the die on the expanding groove side to deform due to loss of support, thus preventing accelerated wear between the punch and die and improving the service life of the aluminum rapid punching equipment.

[0015] Preferably, the die cavity is further provided with a second limiting groove, and the expansion slider is provided with a third limiting groove. An L-shaped rod is hinged inside the second limiting groove. A torsion spring is provided at the hinge point between the L-shaped rod and the inner wall of the rectangular groove. The torsion spring pushes one end of the L-shaped rod to rotate into the third limiting groove and fit against the inner wall of the third limiting groove. The distance between the other end of the L-shaped rod and the inner wall of the punching hole is A, where A ≥ 1 mm.

[0016] As is easily understood, the transmission assembly starts driving the expansion assembly after the pressing rod is in place. This causes the punch to push the scrap material, and the clogged scrap material keeps pressing the pressing rod, triggering the transmission assembly. At this point, the punch hasn't yet left the punch hole when the expansion slider begins to move. Even as the punch leaves the punch hole, it still applies pressure to the inner wall of the punch hole. Without the support of the expansion slider, the punch hole is prone to deformation under long-term compression. Furthermore, as the punch leaves the punch hole, the pressing rod is also resetting, which can cause the unsupported scrap material to be trapped between the pressing rod and the punch, resulting in incomplete scrap removal. Therefore, this design addresses this issue by... An L-shaped rod is installed on the die. When the punch pushes the scrap to trigger the transmission assembly, one side of the L-shaped rod abuts against the punch, and the other side abuts against the inner wall of the limiting groove. This means that the expansion slider cannot move until the punch leaves the L-shaped rod. The expansion slider only begins to slide after the punch leaves the punch hole. Therefore, this design further avoids the deformation of the inner wall of the expansion groove due to the punch's pressure, and further improves the service life of the aluminum parts rapid punching and stamping equipment. In addition, this design also avoids the possibility that scrap that has lost its support may be stuck between the pressing rod and the punch, resulting in the scrap not being completely removed. Therefore, this design also improves the scrap removal efficiency of the expansion assembly.

[0017] Preferably, the control slider has two sliding grooves, which are located on one side of the two limiting grooves respectively. A support block is slidably connected inside the sliding groove, and the two support blocks are in contact with the two limiting blocks respectively. A pressing spring is provided inside the sliding groove. One end of the pressing spring is fixedly connected to the support block, and the other end is fixedly connected to the inner wall of the sliding groove. The sliding direction of the support block is parallel to the lower surface of the die.

[0018] As is easily understood, when the control slider is pushed by rack two, it gradually moves away from limit block one until it is completely away from limit block one. At this point, limit block one, having lost the support of the control slider, is squeezed by the expansion slider and rotates. One end of limit block one rotates into the mounting base. When the control slider resets, it will impact the end of limit block one located in the mounting base, causing wear on both limit block one and the control slider. It may even cause the control slider to jam and fail to reset. This design addresses this by setting support block one on the control slider. When the control slider and expansion slider reset, limit block one is pushed by a torsion spring and rotates into limit groove one. At this point, the end of limit block one located in the mounting base will squeeze support block one and move out of the mounting base. Therefore, support block one not only buffers the collision between limit block one and the control slider, reducing wear between them and improving their service life, but also prevents the expansion component from failing due to jamming during control slider reset.

[0019] Preferably, the inner wall of the punching hole is further provided with a pressing groove, and a second support block is slidably connected to the pressing groove. One end of the second support block extends into the punching hole and is fixedly connected to the pressing rod.

[0020] As is easily understood, when waste material clogs the inside of the punching hole, due to the different deformation and falling posture of the waste material, it may clog the inside of the punching hole at an angle. At this time, the clogged waste material, after being squeezed, will not exert vertical downward pressure on the pressing rod, but rather exert a downward angled pressure on the pressing rod. Under this pressure, the pressing rod may deform or even break. This design, by setting a support block two on one side of the pressing rod that can move with the pressing rod, ensures that when the pressing rod is subjected to downward angled pressure, the pressure acting on the pressing rod is distributed on the inner wall of the punching hole through the support block two, thereby preventing the pressing rod from deforming under force. Therefore, this design ensures that the transmission component can cope with waste material falling in various postures, improving the reliability of the transmission component.

[0021] Preferably, both the punching hole and the control slider are provided with inclined grooves, which are located at the edge where the punching hole contacts the arc surface, and at both ends of the arc surface.

[0022] As is easily understood, since the inner wall of the punching hole and the arc surface on the expansion slider are two semicircles with the same axis, and the width at both ends of the semicircles is equal to the diameter of the punching hole, when waste is blocked inside the punching hole, if the blocked waste happens to be supported at the two ends of the two semicircles of the punching hole or the arc surface, when the expansion slider is driven by the transmission component to move, the waste may still be supported by the punching hole or the arc surface on the expansion slider, thus preventing the waste from falling off smoothly. This design improves the cleaning effect of the expansion component on waste by opening inclined grooves on both the punching hole and the control slider. The inclined grooves are located at the edge of the punching hole and the edge of the arc surface. Therefore, when the expansion slider is driven by the transmission component to move, the waste cannot be supported in the punching hole or the arc surface.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. This invention incorporates an expansion component and a transmission component inside the mounting base. When scrap material gets stuck in the punching hole and cannot fall out, it accumulates continuously during punching. At this point, the pressing rod moves, and the transmission component drives the expansion slider inside the adjustment component to move, increasing the diameter of the punching hole. Consequently, the scrap material accumulated inside the punching hole loses its support from the inner wall of the punching hole and falls out. Therefore, this design avoids scrap material clogging the punching hole. Furthermore, this design only activates when scrap material accumulates, thus reducing wear on the expansion component and the transmission component and improving their service life.

[0025] 2. This invention features a control slider inside the mounting base. As waste material accumulates inside the punching hole, it presses against the pressing rod, causing the rod to move. The rectangular block then presses against the expansion spring inside the rectangular groove. At this point, the expansion slider gradually moves away from the punching hole, increasing the diameter of the punching hole and preventing waste material from clogging it. Furthermore, the design includes an arc surface at one end of the expansion slider, the curvature of which matches the curvature of the inner wall of the punching hole. This reduces wear between the waste material and the expansion slider as it slides inside the punching hole, thus improving the service life of the expansion assembly.

[0026] 3. This invention features a rack inside the mounting base. When the pressing rod moves, the rack moves along with it, driving gear one to rotate. This causes the connecting rod to rotate, and gear two rotates along with the connecting rod. Furthermore, rack two pushes the control slider to compress the reset spring, thereby driving the expansion assembly to work. This design is simple and compact, easy to maintain, and can utilize the pressure generated by the pressing rod when waste material accumulates in the punch hole to drive the expansion assembly, eliminating the need for additional power components and saving on manufacturing and maintenance costs.

The transmission assembly includes a rack 16, which is fixedly connected to the pressing rod 9. A connecting rod is rotatably connected inside the mounting base 6. 17. The mounting base 6 also has a gear 18 inside, and a rack 16 is fixedly connected to the connecting rod 17. The gear 18 meshes with the rack 16. The mounting base 6 also has a gear 29 inside, and there are two gears 29. Both gears 29 are fixedly connected to the connecting rod 17, and the two gears 29 are respectively on both sides of the gear 18. The mounting base 6 also has a rack 20 inside, and there are two racks 20. The two racks 20 mesh with the two gears 29 respectively, and both racks 20 are fixedly connected to the control slider 10. The mounting base 6 also has a return spring 21 inside. One end of the return spring 21 is fixedly connected to the control slider 10, and the other end is fixedly connected to the inner wall of the mounting base 6. The ratio of the number of teeth of the gear 18 to the gear 29 is 1:2.

[0040] Please see Figures 1 to 9The expansion slider 7 has two limiting grooves 22. The die 2 has two limiting blocks 23 hinged to it. A torsion spring is provided at the hinge point between the limiting block 23 and the die 2. The torsion spring pushes one end of the limiting block 23 to rotate into the limiting groove 22. The plane of the limiting block 23 near the punch hole 5 is in contact with the inner wall of the limiting groove 22. The other plane of the limiting groove 22 is in contact with the control slider 10. The expansion slider 7 has a limiting plane that is in contact with the surface of the die 2. The die 2 also has a limiting groove 24. The expansion slider 7 has a limiting groove 25. An L-shaped rod 26 is hinged inside the limiting groove 24. The L-shaped rod 26 is hinged to the inner wall of the rectangular groove 13. A torsion spring is provided, which pushes one end of the L-shaped rod 26 to rotate into the inner wall of the limiting groove 25 and fits against the inner wall of the limiting groove 25. The distance between the other end of the L-shaped rod 26 and the inner wall of the punching hole 5 is A, where A = 1mm. Two sliding grooves 27 are provided on the control slider 10. The two sliding grooves 27 are located on the sides of the two limiting grooves 22 respectively. Support blocks 28 are slidably connected inside the sliding grooves 27. The two support blocks 28 are in contact with the two limiting blocks 23 respectively. A pressing spring 29 is provided inside the sliding grooves 27. One end of the pressing spring 29 is fixedly connected to the support block 28, and the other end is fixedly connected to the inner wall of the sliding groove 27. The sliding direction of the support block 28 is parallel to the lower surface of the die 2. The inner wall of the punching hole 5 is also provided with a pressing groove 30. A support block 2 31 is slidably connected to the pressing groove 30. One end of the support block 2 31 extends into the punching hole 5 and is fixedly connected to the pressing rod 9. Both the punching hole 5 and the control slider 10 are provided with inclined grooves 32. The inclined grooves 32 are located at the edge of the punching hole 5 that contacts the arc surface 15, and at both ends of the arc surface 15.

[0041] Please see Figures 1 to 9 When waste material clogs the inside of the punching hole 5, it is squeezed by the punch 3 and continuously accumulates inside the punching hole 5. The accumulated waste material inside the punching hole gradually increases and continuously squeezes the pressing rod 9, causing the pressing rod 9 to move. The support block 31 at one end of the pressing rod 9 slides inside the sliding groove 27 and moves with the pressing rod 9. The rack 16, which is fixedly connected to the pressing rod 9, also moves with the pressing rod 9. At this time, the rack 16 pushes the gear 18 to rotate, and the gear 18 in turn drives the connecting rod 17 to rotate. The rotation of the connecting rod 17 causes the gears 19, which are fixedly connected to both ends of the connecting rod 17, to rotate with the connecting rod 17. At this time, the racks 20 on both sides of the gear 18 begin to move, and the racks 20 push the control slider 10 to compress the return spring 21 and move.

[0042] At this time, the rectangular block 12 at one end of the control slider 10 moves together with the control slider 10. The rectangular block 12 will squeeze the expansion spring 14 inside the rectangular groove 13. During the movement of the control slider 10, the limiting block 23 on the die 2 will gradually approach the edge of one side of the control slider 10. The control slider 10 continues to move. When the limiting block 23 approaches the edge of one side of the control slider 10 and is about to move away, the punch 3 performs another punching. The waste material accumulated inside the punching hole 5 will push the pressing rod 9 a certain distance. At this time, the control slider 10 moves again. At this time, the control slider 10 moves away from the limiting block 23. The limiting block 23 loses the support of the control slider 10 and no longer applies pressure to the inner wall of the limiting groove. At this time, the expansion slider 7 loses the pressure of the limiting block 23 and is about to move under the push of the expansion spring 14. At this time, the L-shaped rod 26 inside the limiting groove 24 on the inner wall of the limiting groove 3 25 on the expansion slider 7 is designed with pressure, causing the L to rotate and contact the punched part that has not yet left. The punch 3 of the punching hole 5 is not yet able to move. When the punch 3 leaves the punching hole 5, the L-shaped rod 26 rotates and leaves the limiting groove 25. At this time, the expanding slider 7 is pushed by the expanding spring 14 to move away from the punching hole 5. At this time, the waste material accumulated inside the punching hole 5 loses the support of the inner wall of the punching hole 5 and falls off. After the blockage waste material is completely cleared, the pressing rod 9 is no longer under pressure. The reset spring 21 inside the mounting base 6 pushes the control slider 10 to reset. The rectangular block 12 pushes the expanding slider 7 to reset. At this time, the limiting block 23 is squeezed by the expanding slider 7 and pushed by the torsion spring to start rotating into the limiting groove 22. The end of the limiting block 23 hits the support block 28 on the control slider 10 and pushes the support block 28 to squeeze the pressing spring 29. When one end of the limiting block 23 completely leaves the inside of the mounting base 6, the control slider 10 again presses against the limiting block 23, so that the limiting block 23 applies pressure to the expanding slider 7.

[0043] The specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiments described above. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
