Description

Technical Field

[0001] This invention relates to the field of forging equipment technology, and specifically to a stamping and forging equipment. Background Technology

[0002] A stamping and forging machine (usually referring to a stamping press) processes sheet metal into parts of various shapes by applying pressure. It uses a punch and a die (upper and lower dies) to apply force to the material, causing localized deformation of the material to form the desired shape.

[0003] The working process of a stamping machine can be roughly divided into four main stages: feeding, positioning, stamping, and unloading. First, the material to be processed is placed in the appropriate position on the machine; next, the die precisely positions the material; then, by applying high pressure, the die causes the material to undergo plastic deformation, forming a specific shape; finally, the stamped part is unloaded, ready for the next cycle of operation.

[0004] After the material is processed by the stamping die, the formed part will remain in the mold groove of the lower die. At this time, the workers need to use tools to remove the workpiece from the mold. This operation is repeated continuously during the material processing, which not only increases the workload of the workers, but also reduces the work efficiency and fails to achieve the purpose of quick demolding.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

[0006] The purpose of this invention is to provide a stamping and forging equipment that can effectively solve the above-mentioned technical problems.

[0007] To achieve the objectives of this invention, the following technical solution is adopted: A stamping and forging equipment includes: a machine base; and a stamping mechanism for stamping and forming materials. The stamping mechanism includes: a linear module fixedly mounted on the machine base; a movable seat mounted on the linear module; an upper die fixedly mounted on the movable seat; a lower die; and an ejector assembly for ejecting the formed parts. The ejection assembly includes: a threaded rod rotatably mounted inside the machine base; a movable plate threadedly connected to the threaded rod; a gear fixedly sleeved on the threaded rod; a rack meshing with the gear; an air collection pipe fixedly mounted on the movable plate; a push rod penetrating the air collection pipe; a top plate fixedly mounted on one end of the push rod; a piston II fixedly mounted on the other end of the push rod; a return spring II for resetting the piston II; and an air supply unit for supplying air into the air collection pipe.

[0008] Furthermore, the air supply unit includes: a positioning frame fixedly installed on the lower mold; a connecting plate installed through the positioning frame; a slide rod fixedly installed on the connecting plate; a guide groove formed on the machine base; a movable frame slidably installed on the slide rod; a fixed pipe fixedly installed on the machine base; a movable rod installed through the fixed pipe; a piston fixedly installed at the end of the movable rod; a return spring for driving the piston to reset; and an air guide pipe connecting the fixed pipe and the air collecting pipe.

[0009] Furthermore, the guide groove is composed of three interconnected straight grooves: a first straight groove, an inclined groove, and a second straight groove, and the slide rod is slidably installed within the guide groove.

[0010] Furthermore, one end of the reset spring is fixedly connected to the piston, and the other end of the reset spring is fixedly connected to the inner wall of the fixed tube.

[0011] Furthermore, one end of the second reset spring is fixedly connected to the second piston, and the other end of the second reset spring is fixedly connected to the inner wall of the gas collecting pipe.

[0012] Furthermore, a slide rail is fixedly installed on the machine base, and a slider is slidably installed on the slide rail, with the slider being fixedly connected to the lower mold.

[0013] Furthermore, the machine base has a movable opening, the movable plate is slidably installed in the movable opening, and the movable plate is fixedly connected to the lower mold.

[0014] Furthermore, the stamping mechanism also includes a clamping plate fixedly mounted on the linkage plate.

[0015] Furthermore, the stamping mechanism also includes: a protective cover fixedly installed on the machine base; a connecting pipe fixedly installed on the protective cover; a connecting rod installed through the connecting pipe; a piston three fixedly installed at the end of the connecting rod; a return spring three for driving the piston three to reset; a bladder fixedly installed inside the machine base; an air guide pipe two connecting the bladder and the connecting pipe; a pressure plate fixedly installed at the end of the rack; and an insertion hole opened on the lower die.

[0016] Furthermore, one end of the reset spring three is fixedly connected to the piston three, and the other end of the reset spring three is fixedly connected to the inner wall of the connecting tube.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a stamping and forging equipment. By setting up a stamping mechanism, the material is fixed during the feeding process to prevent material displacement during stamping and affecting stamping quality. On the other hand, the parts are automatically ejected during the unloading process, making it convenient for workers to pick up the materials. This greatly reduces the workload of workers, improves work efficiency, and achieves the purpose of rapid demolding.

[0018] 2. The present invention provides a stamping and forging equipment. When the material moves from the initial position to directly below the upper die, the rack and gear meshing ends, allowing the rack to continue moving downwards while the lower die stops moving. The rack drives the pressure plate downwards and compresses the bladder. The gas in the bladder is transported to the connecting pipe through the second air guide pipe, increasing the air pressure in the connecting pipe and driving the third piston to move. The third piston drives the connecting rod to move, causing the connecting rod to insert into the insertion hole. Through the cooperation between the connecting rod and the insertion hole, the lower die can be limited during the stamping process, preventing the lower die from displacement due to external forces, thereby ensuring the accuracy of stamping.

[0024] like Figures 1 to 7 As shown, the present invention provides a stamping and forging equipment, comprising: a machine base 1; and a stamping mechanism for stamping and forming materials.

[0025] The stamping mechanism includes: a linear module 2 fixedly mounted on the machine base 1; a movable seat 3 mounted on the linear module 2; an upper die 4 fixedly mounted on the movable seat 3; a lower die 6; a slide rail 11 fixedly mounted on the machine base 1; a slider 12 slidably mounted on the slide rail 11; and a lower die 6 fixedly connected to the lower die 6; and an ejection assembly for ejecting the formed parts.

[0026] The ejection assembly includes: a threaded rod 9 rotatably mounted inside the machine base 1; a movable plate 10 threadedly connected to the threaded rod 9, the machine base 1 having a movable opening, the movable plate 10 being slidably mounted inside the movable opening, and the movable plate 10 being fixedly connected to the lower mold 6; a gear 8 fixedly sleeved on the threaded rod 9; a rack 7 meshing with the gear 8, the rack 7 being fixedly mounted on the movable seat 3; an air collecting pipe 27 fixedly mounted on the movable plate 10; an ejector rod 26 penetrating and mounted on the air collecting pipe 27; a top plate 36 fixedly mounted on one end of the ejector rod 26; a piston 25 fixedly mounted on the other end of the ejector rod 26; a return spring 24 that drives the piston 25 to return to its original position, one end of the return spring 24 being fixedly connected to the piston 25, and the other end of the return spring 24 being fixedly connected to the inner wall of the air collecting pipe 27; and an air supply unit for supplying air to the air collecting pipe 27.

[0027] The air supply unit includes: a positioning frame 13 fixedly installed on the lower mold 6; a connecting plate 16 installed through the positioning frame 13; a slide rod 15 fixedly installed on the connecting plate 16; a guide groove 14 opened on the machine base 1; a movable frame 18 slidably installed on the slide rod 15; a fixed pipe 22 fixedly installed on the machine base 1; a movable rod 19 installed through the fixed pipe 22; a piston 20 fixedly installed at the end of the movable rod 19; a return spring 21 that drives the piston 20 to reset; an air guide pipe 23 connecting the fixed pipe 22 and the air collecting pipe 27; the guide groove 14 is composed of a straight groove 1, an inclined groove, and a straight groove 2 that are interconnected, and the slide rod 15 is slidably installed in the guide groove 14; one end of the return spring 21 is fixedly connected to the piston 20, and the other end of the return spring 21 is fixedly connected to the inner wall of the fixed pipe 22.

[0028] The stamping mechanism also includes a clamping plate 17 fixedly mounted on the connecting plate 16.

[0029] When stamping materials, the material to be processed is placed in the positioning frame 13. The positioning frame 13 can quickly position the material and prevent the material from slipping off the top of the lower die 6 when the lower die 6 moves.

[0030] When placing the material, the lower mold 6 is in the initial position.

[0031] At this time, the linear module 2 is activated, which drives the movable seat 3 to move downward. The movable seat 3 drives the upper mold 4 to move downward, and at the same time, it drives the rack 7 to move downward. The rack 7 drives the gear 8 to rotate, the gear 8 drives the threaded rod 9 to rotate, the threaded rod 9 drives the moving plate 10 to move, the moving plate 10 drives the lower mold 6 to move, and the lower mold 6 drives the positioning frame 13 to move, thereby driving the material to move.

[0032] Through the cooperation of slider 12 and slide rail 11, the lower mold 6 moves along the axial direction of threaded rod 9, thereby moving the material from the initial position to directly below the upper mold 4.

[0033] Since only a portion of the rack 7 is equipped with toothed blocks, when the material moves from the initial position to directly below the upper die 4, the rack 7 and gear 8 stop meshing. This allows the lower die 6 to stop moving as the rack 7 continues to move downwards, thus causing the upper die 4 and lower die 6 to close, thereby stamping the material into parts.

[0034] When the positioning frame 13 moves, it can drive the connecting plate 16 to move, and the connecting plate 16 drives the slide rod 15 to move, so that the slide rod 15 moves along the path of the guide groove 14. During this process, the slide rod 15 slides along the path of straight groove one, inclined groove and straight groove two in sequence.

[0035] When the slide rod 15 moves along the path of the straight groove one, the distance between the two connecting plates 16 remains unchanged, that is, the distance between the two clamping plates 17 remains unchanged. When the slide rod 15 enters the inclined groove from the straight groove one and moves along the path of the inclined groove, the two slide rods 15 move closer to each other, which can drive the two connecting plates 16 to move closer to each other. The two connecting plates 16 drive the adjacent clamping plates 17 to move closer to each other, thereby clamping and fixing the material. When the slide rod 15 enters the straight groove two from the inclined groove, the clamping plates 17 complete the fixing of the material. At this time, the slide rod 15 continues to move along the path of the straight groove two, so that the two clamping plates 17 maintain the clamping state of the material, avoiding the material from shifting during stamping and affecting the stamping quality.

[0036] It should be noted that the material is preferably a rectangular sheet metal part. When the material is placed in the positioning frame 13, the bottom of the material abuts against the top of the lower mold 6, and the side wall of the material away from the clamping plate 17 fits against the inner wall of the positioning frame 13.

[0037] As the two sliding rods 15 approach each other, they can move the adjacent movable frame 18, causing the two movable frames 18 to move closer together. The movable frame 18 then moves the adjacent movable rod 19, which in turn moves the adjacent piston 20. The piston 20 then stretches the adjacent return spring 21, allowing the gas in the gas collecting pipe 27 to be drawn into the fixed pipe 22 through the gas guide pipe 23. At this time, the return spring 24 returns to its stretched state, causing the piston 25 to move downward. The piston 25 then moves the ejector rod 26 downward, which in turn moves the top plate 36 downward. When the sliding rod 15 moves into the straight groove 2, the top plate 36 abuts against the bottom of the mold cavity of the lower mold 6, thus not affecting subsequent stamping operations.

[0038] After the material is stamped, the linear module 2 drives the upper die 4 and rack 7 to reset upwards. The rack 7 drives the gear 8 to rotate in the opposite direction, and the gear 8 drives the threaded rod 9 to rotate in the opposite direction, thereby driving the lower die 6 to move to the initial position.

[0039] During this process, the slide bar 15 slides along the path of straight groove 2, inclined groove and straight groove 1 in sequence, thereby causing the two movable frames 18 to move away from each other and the two clamping plates 17 to move away from each other.

[0040] When the slide bar 15 enters the straight groove from the inclined groove, the two clamping plates 17 are reset, ready for subsequent use.

[0041] When the two movable frames 18 move away from each other, they can drive the adjacent movable rod 19 to move. The movable rod 19 drives the adjacent piston 20 to move. The piston 20 drives the adjacent return spring to compress. At this time, the air in the fixed tube 22 is compressed and transported to the air collection tube 27 through the air guide tube 23, which increases the air pressure in the air collection tube 27. This drives the piston 25 to move upward. The piston 25 drives the ejector rod 26 to move upward. The ejector rod 26 drives the top plate 36 to move upward. The top plate 36 pushes the molded part upward, so that the part is automatically ejected from the mold cavity of the lower mold 6. This makes it easier for the staff to pick up the material, greatly reduces the workload of the staff, improves the work efficiency, and achieves the purpose of rapid demolding.

[0042] In this invention, the stamping mechanism serves two purposes: firstly, it fixes the material during the feeding process to prevent material displacement during stamping and thus maintain stamping quality; secondly, it automatically ejects the parts during the unloading process, facilitating material handling by workers, greatly reducing their workload, improving work efficiency, and achieving rapid demolding.

[0043] The stamping mechanism also includes: a protective cover 5 fixedly installed on the machine base 1; a connecting pipe 35 fixedly installed on the protective cover 5; a connecting rod 34 installed through the connecting pipe 35; a piston 33 fixedly installed at the end of the connecting rod 34; a return spring 32 that drives the piston 33 to reset; a bladder 29 fixedly installed inside the machine base 1; a vent pipe 30 connecting the bladder 29 and the connecting pipe 35; a pressure plate 28 fixedly installed at the end of the rack 7; and an insertion hole 31 opened on the lower die 6. One end of the return spring 32 is fixedly connected to the piston 33, and the other end of the return spring 32 is fixedly connected to the inner wall of the connecting pipe 35.

[0044] When the material moves from the initial position to directly below the upper mold 4, the rack 7 and gear 8 stop meshing, causing the rack 7 to continue moving downwards while the lower mold 6 stops moving. The rack 7 drives the pressure plate 28 to move downwards and compresses the bladder 29. The gas in the bladder 29 is transported to the connecting pipe 35 through the second air guide pipe 30, which increases the air pressure in the connecting pipe 35 and drives the third piston 33 to move. The third piston 33 drives the connecting rod 34 to move, so that the connecting rod 34 is inserted into the insertion hole 31 and causes the return spring 32 to stretch.

[0045] By cooperating with the connecting rod 34 and the insertion hole 31, the lower die 6 can be limited during the stamping process to prevent the lower die 6 from being displaced by external forces, thereby ensuring the accuracy of stamping.

[0046] After the material is stamped, the upper die 4 returns to its original position, and the pressure plate 28 releases its pressure on the bladder 29. At this time, the gas in the connecting pipe 35 is drawn into the bladder 29. Through the elastic force of the return spring 32, the piston 33 is driven to return to its original position, thereby causing the connecting rod 34 to separate from the insertion hole 31, and thus releasing the limit on the lower die 6.

[0047] In this invention, the stamping mechanism serves two purposes: firstly, it fixes the material during the feeding process to prevent material displacement during stamping and thus maintain stamping quality; secondly, it automatically ejects the parts during the unloading process, facilitating material handling and significantly reducing workload, improving efficiency, and achieving rapid demolding. Furthermore, it limits the lower die 6 during material feeding to prevent displacement due to external forces, thereby ensuring stamping accuracy.
