Since the automobile industry has a strong industrial correlation, it is regarded as an important symbol of a country's economic development level. Stamping is a relatively important process in automobile manufacturing. Stamping is a forming method that relies on presses and dies to apply external forces to plates, strips, pipes and profiles to produce plastic deformation or separation, thereby obtaining workpieces of the required shape and size. Stamping and forging belong to plastic processing, collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. Among the steel materials in the world, 60% to 70% are plates, most of which are stamped into finished products. Stamping is a processing method with high production efficiency and low material consumption. The stamping process is suitable for the production of large batches of parts and products, which is easy to realize mechanization and automation, and has high production efficiency. At the same time, stamping production can not only strive to achieve less waste and no waste production, but also make full use of scraps in some cases.

[0021] As a preferred embodiment, a plurality of air holes are formed at the bottom of the outer surface of one of the lower molds, and the plurality of air holes are evenly distributed inside the stamping platform.

[0022] The technical effect of adopting the above further solution is: the arrangement of evenly distributed air holes is used to eject the workpiece and provide sufficient power, thereby ensuring even force on multiple surfaces.

[0023] A method for using a high-efficiency punching machine for processing automobile parts comprises the following steps:

[0024] S1. Place two workpieces above the two lower dies respectively, and then drive the upper punch to press down through the downward pressure of the lifting column, and then drive the upper upper die to approach the lower die to extrude and punch the workpiece. At the same time, in the process of the upper punch moving downward, the connecting rod pulls the slide plate to slide on the inner wall of the slide slot, driving the pressure rod to move downward, thereby pressing the piston rod to move downward on the inner wall of the stroke channel, squeezing the gas on the inner wall of the top air pump through the outlet hole into the inside of the pipeline, and then the subsequent gas is pressed into the inside of the bottom air pump through the pipeline. The internal air pressure of the bottom air pump gradually increases, and then pushes the piston support rod to drive the lower punch to move up, and then drives the lower die on the top of the lower punch to move toward the adjacent upper die to punch the bottom workpiece.

[0025] S2. The output shaft of the motor rotates to drive the rotation of the rotating shaft. The rotating shaft is connected to a valve switch for closing and opening the air valve, thereby reducing or maintaining the air pressure on the inner wall of the bottom air pump. When the stamping is completed, the valve switch is turned to release the pressure inside the bottom air pump. The piston support rod drives the lower punch to gradually reset. The gas inside the bottom air pump is pressed into the interior of the processing device through the pressure relief pipe and sprayed out from multiple air holes, thereby lifting the workpiece stuck in the upper lower mold to avoid being stuck in the upper lower mold.

[0026] S3. An external power source drives the connecting shaft to rotate, wherein the first vertical gear is meshed with the second vertical gear, which in turn drives the threaded rod to rotate. The threaded slider is slidably embedded in the outer surface of the punching table. As the threaded rod rotates, the threaded slider threadedly connected to the threaded rod is driven to slide on the surface of the punching table, thereby pushing the workpiece out of the processing position until the workpiece is pushed to the upper surface of the right side of the conveyor belt and then transmitted by the conveyor belt.

[0027] S4. The external power source drives the left roller to rotate, and then drives the conveyor belt to rotate through the conveyor belt, so as to convey the processed workpiece to the subsequent process position, thereby realizing the transfer of the processed workpiece.

[0028] Compared with the prior art, the advantages and positive effects of the present invention are:

[0029] The camming mechanism of the present invention is a kind of high-efficiency punching machine, and its upper and lower parts are connected with the camming mechanism, and its upper and lower parts are connected with the camming mechanism, so that the camming mechanism can be directly connected with the camming mechanism, and the camming mechanism can be directly connected with the camming mechanism.

[0030] 2. The present invention makes great use of the downward pressure power of the top, and adjusts the internal pressure by controlling the switch of the air valve of the bottom air pump through the motor. When the pressure is released, the internal gas is pressed into the interior of the stamping table through the pressure relief pipe and sprayed out from multiple air holes to detach the workpiece stuck on the surface of the lower die, avoiding jamming due to excessive pressure. Since the lower die at the bottom is set in an upper position, it will fall freely under the action of gravity without the need for additional spray holes, which is more convenient for disassembly after workpiece processing and avoids the situation where the workpiece is stuck in the processing position after processing. Compared with the traditional high-efficiency stamping machine for processing automotive parts, the present invention solves the problem that after the punching head at the top of the traditional stamping device presses the workpiece, due to different mold designs and pressing strengths, and using the pressing method as the stamping condition, the workpiece after pressing and stamping is often still stuck on the bottom stamping mold after the top punching head is lifted, and the staff often needs to use tools to pick it out, which is more troublesome to use, thereby improving production efficiency.

[0031] 3. The present invention drives the rotation of the connecting shaft through an external power source, and then drives the threaded slider to slide on the surface of the punching table through the meshing first vertical gear and the second vertical gear, so that the threaded slider can push and transfer the workpiece that is no longer stuck. The arrangement of multiple second vertical gears and threaded rods saves the setting of the power source, and only a few power sources are needed to achieve the rotation effect of multiple threaded rods. Compared with traditional high-efficiency stamping machines for processing automotive parts, the present invention reduces the setting of power sources and reduces production costs.

[0032] 4. The present invention drives the roller on one side to rotate through an external power source, and multiple rollers drive the conveyor belt for transmission, thereby conveying and moving the processed workpiece. The external moving track can be set up to the position of the subsequent process to facilitate subsequent processing, and can be combined with automatic loading to achieve automated stamping. Compared with the traditional high-efficiency stamping machine for processing automotive parts, the present invention greatly reduces the labor cost. BRIEF DESCRIPTION OF THE DRAWINGS

The inner wall of the bottom air pump 104 is movably embedded with a piston support rod 10, and a lower punching platform 103 is fixedly installed on the top of the outer surface of the piston support rod 10. The multiple multi-section rods 102 are fixedly installed at the bottom of the outer surface of the lower punching platform 103. The up and down movement of the lifting column 401 drives the movement of the upper punch 402. The connecting rod 403 here serves as a connecting device between the slide plate 404 and the upper punch 402, so that the slide plate 404 moves up and down at the same time as the lifting column 401, and then drives the piston rod 407 to pressurize the interior of the top air pump 7, and the gas entering the interior of the top air pump 7 during the pullback is pressed into the interior of the bottom air pump 104 through the pipeline 701, thereby pushing the piston support rod 10 to lift the lower punch 103, so that the upper punch 402 and the lower punch 103 on the upper and lower sides move toward the direction of the stamping table 5 at the same time. There are two workpieces to be processed, which are placed at the positions of the two lower molds 12 respectively.

Since the lower die 12 at the bottom is set in an upper position, it will fall freely under the action of gravity without the need for additional spray holes, which is more convenient for disassembly of the workpiece after processing, and avoids the situation where the workpiece is stuck in the processing position after processing.In addition, the connecting shaft 6 is driven to rotate by an external power source, and then the first vertical gear 601 and the second vertical gear 602 are meshed to drive the threaded slider 605 to slide on the surface of the punching table 5, so that the threaded slider 605 can push and transfer the workpiece that is no longer stuck.

The evenly distributed air holes 501 are arranged to eject the workpiece from the card and provide sufficient power to ensure uniform force on multiple surfaces.

[0054] A method for using a high-efficiency punching machine for processing automobile parts comprises the following steps:

[0055] S1. Place the two workpieces above the two lower molds 12 respectively, and then drive the upper punch 402 to be pressed down by the downward pressure of the lifting column 401, and then drive the upper upper mold 11 to be close to the lower mold 12 to squeeze and punch the workpiece. At the same time, in the process of the upper punch 402 moving downward, the connecting rod 403 pulls the slide plate 404 to slide on the inner wall of the slide groove 405, driving the pressure rod 406 to move downward, thereby pressing the piston rod 407 to move downward on the inner wall of the stroke channel 703, squeezing the gas on the inner wall of the top air pump 7 through the outlet hole 704 into the inside of the pipeline 701, and then the subsequent gas is pressed into the inside of the bottom air pump 104 through the pipeline 701. The internal air pressure of the bottom air pump 104 gradually increases, and then pushes the piston support rod 10 to drive the lower punch 103 to move upward, and then drives the lower mold 12 on the top of the lower punch 103 to move toward the adjacent upper mold 11 to punch the bottom workpiece.

[0056] S2. The output shaft of the motor 101 rotates to drive the rotation of the rotating shaft 9. The rotating shaft 9 is connected to a valve switch 801 for closing and opening the air valve 8, thereby reducing or maintaining the air pressure on the inner wall of the bottom air pump 104. When the stamping is completed, the valve switch 801 is turned to relieve the pressure inside the bottom air pump 104. The piston support rod 10 drives the lower punch 103 to gradually reset. The gas inside the bottom air pump 104 is pressed into the interior of the processing device 3 through the pressure relief pipe 901 and sprayed out from multiple air holes 501, thereby lifting the workpiece stuck in the upper lower mold 12 to avoid being stuck in the upper lower mold 12.

[0057] S3. An external power source drives the connecting shaft 6 to rotate, wherein the first vertical gear 601 is meshed with the second vertical gear 602, thereby driving the threaded rod 603 to rotate, and the threaded slider 605 is slidably embedded in the outer surface of the punching table 5. As the threaded rod 603 rotates, the threaded slider 605 threadedly connected to the threaded rod 603 is driven to slide on the surface of the punching table 5, thereby pushing the workpiece out of the processing position until the workpiece is pushed to the upper right surface of the conveyor belt 203 and then transmitted by the conveyor belt 203.

[0058] S4. The external power source drives the left roller 202 to rotate, and then drives the conveyor belt 203 to rotate through the conveyor belt 203, so as to convey the processed workpiece to the subsequent process position, thereby realizing the transfer of the processed workpiece.

[0059] Working principle: The upper punching platform 402 is driven to move up and down by the lifting column 401. The connecting rod 403 here serves as a connecting device between the slide plate 404 and the upper punching platform 402, so that the slide plate 404 moves up and down at the same time as the lifting column 401, and then drives the piston rod 407 to pressurize the inside of the top air pump 7, and the gas entering the top air pump 7 during the pullback is pressed into the inside of the bottom air pump 104 through the pipeline 701, thereby pushing the piston support rod 10 to lift the lower punching platform 103, so as to realize the upper and lower sides of the upper punching platform 40 2 and the lower punch 103 move toward the direction of the punching table 5 at the same time. There are two workpieces to be processed, which are placed at the positions of the two lower dies 12 respectively. As the upper punch 402 and the lower punch 103 move, the top upper die 11 and the bottom lower die 12 gradually squeeze the workpieces to complete the punching. Compared with the traditional punching method, the work efficiency is greatly improved, and two workpieces can be punched at the same time. The upper die 11 is a detachable stamping die, which is convenient for punching workpieces of different specifications and styles. In addition, the downward pressure of the top is greatly utilized. Force, the switch of the air valve 8 of the bottom air pump 104 is controlled by the motor 101 to adjust the internal pressure. When the pressure is released, the internal gas is pressed into the interior of the stamping table 5 through the pressure relief pipe 901, and is ejected from multiple air holes 501 to detach the workpiece stuck on the surface of the lower die 12 to avoid being stuck due to excessive pressure. Since the lower die 12 at the bottom is set in an upper position, it will fall freely under the action of gravity without the need for additional spray holes, which is more convenient for disassembly after the workpiece is processed, and the situation where the workpiece is stuck in the processing position after processing is avoided. In addition, the rotation of the connecting shaft 6 is driven by an external power source, and then the threaded slider 605 is driven to slide on the surface of the stamping table 5 through the meshing connection of the first vertical gear 601 and the second vertical gear 602, so that the threaded slider 605 can push and transfer the workpiece that is no longer stuck. Subsequently, the roller 202 on one side is driven to rotate by the external power source, and the multiple rollers 202 drive the conveyor belt 203 to transmit, so that the processed workpiece is conveyed and moved, and the external moving track can be set to the position of the subsequent process to facilitate subsequent processing.

Two workpieces are placed above the two lower molds (12) respectively, and then the upper punch (402) is pressed down by the lifting column (401), thereby driving the upper mold (11) to approach the lower mold (12) to press and punch the workpieces. At the same time, during the downward movement of the upper punch (402), the connecting rod (403) pulls the slide plate (404) to slide on the inner wall of the slide groove (405), driving the pressure rod (406) to move downward, thereby pressing the piston rod (407) in the stroke. The inner wall of the channel (703) moves downward, squeezing the gas on the inner wall of the top air pump (7) through the outlet hole (704) into the interior of the pipe (701), and then the gas is pressed into the interior of the bottom air pump (104) through the pipe (701). The internal air pressure of the bottom air pump (104) gradually increases, and then the piston support rod (10) drives the lower punch (103) to move upward, and then drives the lower die (12) on the top of the lower punch (103) to move toward the adjacent upper die (11), so as to punch the bottom workpiece; S2, the output shaft of the motor (101) rotates to drive the rotating shaft (9) to rotate. The rotating shaft (9) is connected to a valve switch (801) for closing and opening the air valve (8), thereby reducing or maintaining the air pressure on the inner wall of the bottom air pump (104). When the punching is completed, the valve switch (801) is rotated to release the pressure inside the bottom air pump (104). The piston support rod (10) drives the lower punch (103) to gradually reset. The gas inside the bottom air pump (104) is pressed into the interior of the processing device (3) through the pressure relief pipe (901) and ejected from the multiple air holes (501), thereby lifting the workpiece stuck inside the upper lower mold (12) to avoid being stuck inside the upper lower mold (12); S3, an external power source drives the connecting shaft (6) to rotate, wherein the first vertical gear (601) is meshedly connected with the second vertical gear (602), thereby driving the threaded rod (603) to rotate, and the threaded slider (605) is slidably embedded in the outer surface of the punching table (5). As the threaded rod (603) rotates, the threaded slider (605) threadedly connected to the threaded rod (603) is driven to slide on the surface of the punching table (5), thereby pushing the workpiece out of the processing position until the workpiece is pushed to the upper surface of the right side of the conveyor belt (203) and then transferred by the conveyor belt (203); S4. An external power source drives the left rotating roller (202) to rotate, and then drives the conveyor belt (203) to rotate through the conveyor belt (203), so as to convey the processed workpiece to the subsequent process position, thereby realizing the transfer of the processed workpiece.
