Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy filter screen forging parts, and specifically relates to a stamping device for processing alloy filter screens. Background Art

[0002] In the processing operation of alloy filter screens, in order to improve the forming quality of workpieces and meet the production dimension requirements, during the forming process, a stamping process is adopted. By using a rigid device or a high-strength tool for stamping, the required size and specifications are formed. The workpieces formed by stamping have high production capacity and stable forming. Different from the traditional stamping of alloy filter screens, to meet the precision requirements of the application of this aluminum alloy filter screen, a precision forging process is used for production, which can improve the strength of the workpiece, making it have characteristics such as high strength, wear resistance, and fatigue resistance. When applied to, for example, the motor oil cooling filtration system, it has technical advantages such as light weight.

[0003] In the prior art, when stamping aluminum alloy filter screen forging parts, the head of the stamping contacts the alloy filter screen, and direct rigid stamping easily causes the stamped material to fall into the forging, which is inconvenient for collection.

[0004] To overcome the above deficiencies, a Chinese patent of the prior art (publication number CN217191893U) discloses an iron part stamping device, including a bracket; a top seat is installed at the top of the bracket; an air compressor is installed at the top of the top seat; a stamping mechanism, a first gripper, and a second gripper are installed at the bottom of the top seat; a control panel is installed on one side of the bracket; the bottom of the bracket is connected to a base; a clamping mechanism is installed at the top of the base, which is convenient to use and has a good stamping effect.

[0005] To overcome the above deficiencies, a Chinese patent of the prior art (publication number CN214290225U) discloses an automatic production line for aluminum stamping parts, including a bottom plate. A punching machine is provided on the right side of the bottom plate, a conveying device is provided on the left side of the bottom plate, the upper side wall of the bottom plate is connected by pipes to four support rods, and the upper ends of the four support rods are connected by pipes to the same recovery tank. An oil injection head is fixedly connected to the upper side wall of the recovery tank through a connecting rod. A box body is fixedly connected to the upper side wall of the bottom plate, a pump body is fixedly connected to the side wall of the box body, the water inlet end of the pump body is fixedly communicated with the side wall of the box body, the water outlet end of the pump body is fixedly communicated with a water outlet pipe, and the end of the water outlet pipe away from the pump body is fixedly communicated with the side wall of the oil injection head. A recovery pipe is fixedly communicated with the side wall of the recovery tank, which can automatically filter impurities in the liquid, avoid impurities from causing blockage of the pump body, reduce the workload of operators, and can facilitate the quick disassembly and assembly of the filter screen plate, improving the work efficiency of operators.

[0006] Although the prior art can overcome the above-mentioned deficiencies, there are still other problems in its operation. For example, when processing aluminum alloy filter screen forgings through stamping equipment, the alloy filter screen formed by processing stamping is likely to fall into the inside of the collection port. After the alloy filter screen is stamped by rigid equipment, due to the fitting degree of the appearance, it is easy to get stuck inside the collection port, making it inconvenient to take out the alloy filter screen, taking a long time, and finally resulting in poor forming quality of the overall aluminum alloy filter screen forgings and unable to guarantee the forming quality of the aluminum alloy filter screen forgings. Summary of the Invention

[0012] Furthermore, the alloy forging protection mechanism is provided with a moving plate, and the middle end of the moving plate is fixedly installed at the output end of the hydraulic rod. And a traction rope is fixedly installed at the rear end of the moving plate, and the middle end of the traction rope fits against the guide pulley. The inner side of the guide pulley is fixedly installed at the rear end of the housing, and the lower end of the traction rope is fixedly installed at the rear end of the movable part.

[0013] Furthermore, a push-out plate is fixedly installed at the front end of the movable part, and the lower end of the push-out plate fits against the upper surface of the mold. And a return spring is provided between the rear end of the movable part and the fixed plate.

[0014] Furthermore, elastic air bags are fixedly installed on the left and right sides at the front end of the fixed plate, and the elastic air bags and the push-out plate form a pressing structure. And an air guide pipe is communicated with the outside of the elastic air bag, and the front end of the air guide pipe is communicated with a jet port. The lower end of the jet port is fixedly installed on the surface of the mold, and the output end of the jet port is aligned with the surface of the groove opened at the center of the mold. A one-way air inlet is installed through the rear end of the elastic air bag, and a one-way valve is arranged inside the one-way air inlet.

[0015] Furthermore, the anti-jamming alloy mechanism is provided with a toothed plate, and the right side of the toothed plate is fixedly installed on the left side of the movable part. And a driving rod is rotatably installed at the rear end of the housing, and a gear is fixedly installed at the upper end of the driving rod.

[0017] Furthermore, a vibration spring is provided between the knocking plate and the mold. And a contact plate is fixedly installed on the left side of the mold, and the left side of the contact plate corresponds to the convex block on the right side of the knocking plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. The aluminum alloy filter screen forging is an aluminum alloy component produced by precision forging process. When the whole equipment is processing, first place the alloy filter screen on the surface of the mold inside the shell. At this time, by starting the hydraulic rod, the output end of the hydraulic rod presses down the alloy filter screen through the stamping part, and then stamps the workpiece into the groove, so as to perform stamping. The workpiece falls into the collection box through the inclined plate for collection, and the stamped workpiece can be taken out conveniently, improving the efficiency of using the stamping equipment, making the operation of the staff simpler and more convenient, achieving the effect of automatic extraction, and thus continuously stamping the processed aluminum alloy filter screen forging. After placing the aluminum alloy filter screen forging to be processed on the mold, through rigid stamping and the close cooperation of each component, the effect of precision processing is achieved, thus ensuring the forming quality of the overall aluminum alloy filter screen forging.

[0019] 2. When the output end of the hydraulic rod drives the stamping part to descend, the moving plate moves downward simultaneously. The descent of the moving plate pulls the traction rope. Under the guidance of the guide wheel, the traction rope drags the movable part backward along the fixed plate. The air jet port blows air at the groove on the surface of the mold and the surface of the push plate. When the elastic airbag is not squeezed, it resets by its own elastic force, and at the same time inhales air through the one-way valve inside the one-way air inlet, so as to avoid the residue of impurities affecting the quality of the stamped finished product and ensure the stamping effect; Furthermore, when the output end of the hydraulic rod drives the stamping part to rise, as the stamping part rises, the moving plate rises and releases the traction rope. At this time, the traction rope releases the movable part, and the push plate moves forward to push the workpiece, so that the workpiece can fall into the collection box along the inclined plate, realizing the effect of automatic collection, without the need for the staff to collect manually, which can save operation steps.

[0020] 3. After the alloy filter screen is stamped, it is easy to fit into the groove on the surface of the mold due to its size. When the stuck force is greater than the force of the compression spring, the workpiece is easily stuck in the groove and cannot be taken out. At this time, when the movable part moves back and forth, the gear is driven to rotate by the toothed plate. When the knocking plate is squeezed by the cam, the knocking plate knocks the contact plate along the limiting rod through the inner convex block. In this way, after the stamping part stamps the alloy filter screen, the mold can be knocked and vibrated to avoid the stamped workpiece being stuck in the groove, achieving the effect of stable extraction, avoiding the problem of being unable to take out, and improving the practicability of the device.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1: As Figure 1 , Figure 2 , Figure 3 and Figure 6The technical solution shown is a stamping device for processing alloy filter meshes. To solve the problem of inconvenient removal of the processed workpieces of alloy filter meshes, it discloses: a housing 1 and a mold 2 arranged inside the housing 1. A groove 3 is formed on the surface of the mold 2. A hydraulic rod 4 is arranged at the upper end of the housing 1. The output end of the hydraulic rod 4 is provided with a stamping part 5. A lifting part 6 is arranged inside the mold 2. An alloy forging self-removing mechanism is arranged at the bottom of the lifting part 6. The alloy forging self-removing mechanism is provided with a push plate 7. The lower end of the push plate 7 is arranged at the upper end of the lifting part 6. The stamping part 5 and the groove 3 are arranged corresponding to each other, and the groove 3 and the stamping part 5 have the same shape. The alloy forging self-removing mechanism is provided with a compression spring 8. The upper end of the compression spring 8 is fixedly installed at the lower end of the lifting part 6. The lower end of the compression spring 8 is fixedly installed at the bottom of the mold 2. A damping rod 9 is arranged between the mold 2 and the lifting part 6. The outer side of the push plate 7 is in contact with the inner wall of the groove 3, and the push plate 7 is slidably connected with the inner wall of the mold 2. A sloping plate 10 is arranged at the front end of the mold 2. A collection box 11 is fixedly installed inside the housing 1. The upper end of the collection box 11 corresponds to the sloping plate 10; During use, place the alloy filter mesh on the surface of the mold 2 inside the housing 1. At this time, by starting the hydraulic rod 4, the output end of the hydraulic rod 4 presses the alloy filter mesh through the stamping part 5, and then stamps the workpiece into the groove 3, so as to perform stamping. When the stamping part 5 presses down, when stamping the filter mesh along the inside of the groove 3, it presses down the push plate 7. On the contrary, when the hydraulic rod 4 drives the stamping part 5 to rise, the lifting part 6 rises under the action of the elastic force of the compression spring 8 itself. Through the setting of the damping rod 9, the reciprocating vibration of the lifting part 6 is avoided, and at the same time, the processed alloy filter mesh can be stably pushed out along the groove 3 through the push plate 7. At this time, as the user toggles it, it falls into the collection box 11 through the sloping plate 10 for collection. The stamping workpiece can be conveniently taken out, the efficiency of using the stamping device is improved, the operation of the staff is made simpler and more convenient, and the effect of automatic removal is achieved. Thus, continuous stamping of the forged parts of the aluminum alloy filter mesh to be processed is carried out. After placing the forged parts of the aluminum alloy filter mesh to be processed on the mold 2, through rigid stamping, the effect of precision processing is achieved, thereby ensuring the forming quality of the forged parts of the aluminum alloy filter mesh.

[0025] Embodiment 2: As Figures 1 - 8The described technical solution, based on the first embodiment, discloses in order to solve the problem of inconvenient collection: a fixed plate 16 is arranged inside the housing 1, alloy forging protection mechanisms are arranged at the front and rear ends of the fixed plate 16, the alloy forging protection mechanism is provided with a movable member 15, and the middle end of the movable member 15 penetrates and is installed at the upper end of the fixed plate 16. The alloy forging protection mechanism is provided with a moving plate 12, and the middle end of the moving plate 12 is fixedly installed at the output end of the hydraulic rod 4. A traction rope 13 is fixedly installed at the rear end of the moving plate 12, and the middle end of the traction rope 13 is in contact with the guide pulley 14. The inner side of the guide pulley 14 is fixedly installed at the rear end of the housing 1. The lower end of the traction rope 13 is fixedly installed at the rear end of the movable member 15. A push plate 17 is fixedly installed at the front end of the movable member 15, and the lower end of the push plate 17 is in contact with the upper surface of the mold 2. A return spring 18 is arranged between the rear end of the movable member 15 and the fixed plate 16. Elastic air bags 19 are fixedly installed on the left and right sides at the front end of the fixed plate 16, and the elastic air bags 19 and the push plate 17 form a pressing structure. The outside of the elastic air bags 19 is communicated with an air guide pipe 20, and the front end of the air guide pipe 20 is communicated with a jet port 21. The lower end of the jet port 21 is fixedly installed on the surface of the mold 2, and the output end of the jet port 21 is aligned with the surface of the groove 3 opened at the center of the mold 2. A one-way air inlet 22 penetrates and is installed at the rear end of the elastic air bag 19, and a one-way valve is arranged inside the one-way air inlet 22; When the output end of the hydraulic rod 4 drives the stamping part 5 to descend, as the moving plate 12 moves downward simultaneously, the descent of the moving plate 12 pulls the traction rope 13. Under the guidance of the guide pulley 14, the traction rope 13 pulls the movable member 15 backward along the fixed plate 16 to move backward. At this time, while the movable member 15 pulls the return spring 18 backward, it drives the push plate 17. At this time, as the push plate 17 moves backward, the push plate 17 squeezes the elastic air bag 19 backward, so that the air inside the elastic air bag 19 is delivered to the jet port 21 through the air guide pipe 20. The jet port 21 blows air onto the surface of the groove 3 on the surface of the mold 2 and the surface of the push plate 7. When the elastic air bag 19 is not squeezed, it resets by its own elastic force, and at the same time inhales air through the one-way valve inside the one-way air inlet 22, so as to avoid the residue of impurities affecting the quality of the stamped finished product and ensure the stamping effect. On the contrary, when the output end of the hydraulic rod 4 drives the stamping part 5 to rise, as the stamping part 5 rises, the moving plate 12 rises and releases the traction rope 13. At this time, the traction rope 13 releases the movable member 15. Under the elastic force of the return spring 18, the movable member 15 moves forward along the fixed plate 16 to reset. At this time, the push plate 7 also takes out the stamped part upward. As the push plate 7 resets, the stamped workpiece is pushed out. The push plate 17 moves forward to push the workpiece, so that the workpiece can fall into the collection box 11 along the inclined plate 10, realizing the effect of automatic collection, without the need for manual collection by the staff, and can save operation steps.

[0026] Embodiment Three: AsFigures 1 - 11 In the technical solution shown, on the basis of Embodiment 2, in order to solve the problem that the processed workpiece is easily stuck, it is disclosed that: a limiting rod 29 is provided on the left side of the mold 2, and an anti-sticking alloy mechanism is provided on the surface of the limiting rod 29. The anti-sticking alloy mechanism is provided with a knocking plate 30, and the front and rear ends of the knocking plate 30 penetrate through the limiting rod 29. The anti-sticking alloy mechanism is provided with a toothed plate 23, and the right side of the toothed plate 23 is fixedly installed on the left side of the movable part 15. A driving rod 25 is rotatably installed at the rear end of the housing 1, and a gear 24 is fixedly installed at the upper end of the driving rod 25. The right side of the gear 24 meshes with the toothed plate 23. A driven rod 27 is rotatably installed inside the housing 1, and a transmission belt 26 is nestedly installed at the upper end of the driven rod 27 through a pulley. The rear end of the transmission belt 26 is nestedly installed at the middle end of the driving rod 25 through a pulley. A cam 28 is fixedly installed at the middle end of the driven rod 27, and the cam 28 is correspondingly arranged with the left side of the knocking plate 30. A vibration spring 31 is arranged between the knocking plate 30 and the mold 2, and a contact plate 32 is fixedly installed on the left side of the mold 2. The left side of the contact plate 32 corresponds to the right convex block of the knocking plate 30; After the alloy filter screen is stamped, it is easy to fit into the groove 3 on the surface of the mold 2 due to its size. When the stuck force is greater than the force of the compression spring 8, the workpiece is easily stuck inside the groove 3 and cannot be taken out. At this time, when the movable part 15 moves back and forth, the toothed plate 23 drives the gear 24 to rotate. When the gear 24 rotates, it can drive the driving rod 25 to rotate. When the driving rod 25 rotates, the driven rod 27 is driven to rotate through the transmission belt 26 and the pulley. When the driven rod 27 rotates, the knocking plate 30 can be squeezed by the cam 28. When the knocking plate 30 is squeezed by the cam 28, the knocking plate 30 knocks the contact plate 32 along the limiting rod 29 through the inner convex block. On the contrary, when the squeezing stops, under the action of the vibration spring 31, while resetting, the vibration effect is improved. In this way, after the stamping part 5 stamps the alloy filter screen, the mold 2 can be knocked and vibrated to prevent the workpiece after stamping from being stuck inside the groove 3, achieving the effect of stable taking out, avoiding the problem of being unable to take out, and improving the practicability of the device.
