Description

Technical Field

[0002] In the automotive parts processing industry, stamping machines are one of the core manufacturing equipment. They apply external force to the material through the press and mold, causing it to undergo plastic deformation or separation to obtain workpieces of specific shapes and sizes. They are mainly used for processing body panels, chassis, fuel tanks, radiators, etc., and have many advantages such as high processing efficiency, low cost and simple operation.

[0003] For example, Chinese patent publication number CN116766659B discloses a punching machine. This device greatly improves the efficiency of mold replacement by installing a rotating upper mold on a slide and a rotating lower mold on a lifting platform, making the use of the punching machine more convenient. There is no need for workers to carry and disassemble the mold, which greatly improves production efficiency.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 8 , the present invention provides a technical solution: An adaptive multi-axis linkage automobile stamping press includes two groups of parallel distributed frames 11, a stamping seat 12 is fixedly connected between the two groups of frames 11, a pushing assembly is provided on the upper side of the stamping seat 12, and the pushing assembly includes a movable groove 32 opened on the outer surface of the upper end of the stamping seat 12, a movable seat 27 is slidably connected to the inner side of the movable groove 32, a slide groove 29 is embedded on the inner side of the stamping seat 12, a slide 30 is slidably connected to the inner side of the slide groove 29, the slide 30 is fixedly connected to a connecting block 31, the upper end of the connecting block 31 is fixedly connected to the movable seat 27, a traction plate 28 is fixedly connected to the outer surface of the slide 30, and the traction plate 28 is fixedly connected to the inner wall of the slide groove 29 at one end away from the slide 30.

[0022] A through slot 42 is embedded on the inner side of the stamping seat 12. The upper and lower ends of the through slot 42 are respectively connected to the inside of the movable slot 32 and the slide slot 29. The connecting block 31 is located inside the through slot 42 and is slidably connected to the through slot 42. The traction plate 28 has a U-shaped structure and is made of elastic material. The number of movable seats 27 and movable slots 32 are both two groups and are symmetrically distributed.

[0023] A driving assembly is provided on the inner side of the stamping seat 12, and the driving assembly includes a movable rod 21 that is slidably connected to the stamping seat 12. A cover plate 22 is fixedly connected to the upper side of the outer surface of the movable rod 21. A receiving groove 23 is provided on the outer surface of the upper end of the stamping seat 12. The lower end of the movable rod 21 passes through the interior of the slide groove 29 and contacts the outer surface of the upper end of the traction plate 28. The fixed frame 13 has a U-shaped structure.

[0024] By adopting the above technical solution, a die 19 for punching the workpiece is provided on the inner side of the frame 11. When the workpiece is stamped, the workpiece is placed on the upper surface of the stamping seat 12. The stamping seat 12 slides and supports the movable seat 27 through the movable groove 32 on its surface. The lower end of the workpiece will be in contact with the upper surface of the movable seat 27. The die 19 moves downward and contacts the upper surface of the workpiece. The workpiece is stamped and shaped by the die 19 in cooperation with the stamping seat 12. The die 19 will be in contact with the upper surface of the cover plate 22 during the downward movement. As the die 19 continues to move downward, the cover plate 22 will be driven to move downward synchronously. The cover plate 22 will drive the movable rod 21 to move downward synchronously during the downward movement. The lower end of the movable rod 21 contacts the upper surface of the traction plate 28, and the middle part of the traction plate 28 is pushed downward by the movable rod 21, so that the traction plate 28 is bent and deformed downward. At this time, one end of the traction plate 28 will pull the slide 30, so that the slide 30 slides inside the slide groove 29 to the side close to the movable rod 21. During the movement, the slide 30 drives the movable seat 27 to move synchronously through the connecting block 31, and drives the workpiece to the lower side of the die 19 through the movable seat 27 to stamp the workpiece. At this time, the cover plate 22 enters the receiving groove 23 under the thrust of the die 19, and the upper surface of the stamping seat 12 can be kept flat by cooperating with the die 19 through the cover plate 22; After the workpiece is stamped, the die 19 is lifted upward. At this time, the traction plate 28 is flipped from the bent state to a straight state under the action of its own elastic force, and the slide 30 is pushed in the opposite direction by the traction plate 28. The slide 30 drives the movable seat 27 to move in the opposite direction through the connecting block 31. The stamped workpiece can be taken out from the bottom side of the die 19 through the movable seat 27, and then the operator removes the workpiece on the surface of the movable seat 27 and puts in a new workpiece. By setting a pushing assembly, the workpiece can be pushed out from the bottom side of the die 19. When the operator takes out and places the workpiece, the damage to the operator's hands caused by the accidental downward movement of the die 19 can be reduced, thereby effectively eliminating the safety hazards during the use of the press and helping to improve the operational safety of the stamping press.

[0025] Specifically, such as Figure 4 As shown, a stamping assembly is provided on the inner side of the frame 11, and the stamping assembly includes a fixed frame 13 fixedly connected to the inner side of the frame 11, a hydraulic rod 18 is fixedly connected to the upper end of the inner surface of the fixed frame 13, and a movable frame 14 is fixedly connected to the lower end of the hydraulic rod 18. The movable frame 14 is located on the inner side of the fixed frame 13 and is in sliding contact with the inner surface of the fixed frame 13. There are two groups of hydraulic rods 18 and they are symmetrically distributed.

[0026] A pressure plate 15 is fixedly connected to the outer surface of the lower end of the movable frame 14, and a positioning pin 17 is engaged with the inner side of the pressure plate 15. The pressure plate 15 is engaged with the die 19 through the positioning pin 17. A reinforcing rib 16 is fixedly connected between the pressure plate 15 and the movable frame 14. The number of pressure plates 15 and positioning pins 17 are several groups and distributed in a parallel array.

[0027] By adopting the above technical solution, in order to be able to carry out stamping operations continuously, a stamping assembly is set up. Before stamping, the die 19 is installed on the lower side of the pressure plate 15 through the locating pin 17. The reinforcing ribs 16 between the movable frame 14 and the pressure plate 15 can effectively improve the structural stability of the pressure plate 15. During operation, the hydraulic rod 18 is started and the frame 11 fixes the hydraulic rod 18 through the fixed frame 13. The driving end of the hydraulic rod 18 drives the movable frame 14 to move downward. The frame 11 slides in contact with both sides of the movable frame 14 to guide the movable frame 14, so that the movable frame 14 moves more smoothly. During the movement, the movable frame 14 drives the die 19 to move downward synchronously through the pressure plate 15, and the workpiece is stamped by the die 19 in cooperation with the stamping seat 12. By setting the stamping assembly, the stamping efficiency of the workpiece can be improved to a certain extent.

[0028] Specifically, such as Figure 4 As shown, a limiting component is provided on the upper side of the movable seat 27, and the limiting component includes a movable groove 26 opened on the inner side of the movable seat 27, and a stop sleeve 24 is slidably connected inside the movable groove 26. A spring 25 is fixedly connected to the lower end of the inner surface of the movable groove 26, and the upper end of the spring 25 is in contact with the top wall of the stop sleeve 24.

[0029] By adopting the above technical solution, the movable groove 26 opened on the surface of the movable seat 27 is used to support the sliding of the stop sleeve 24, and the spring 25 inside the movable groove 26 is used to elastically support the stop sleeve 24. During the downward movement of the die 19, the stop sleeve 24 is driven to move downward, so that the stop sleeve 24 is moved to the inside of the movable groove 26 to accommodate the stop sleeve 24, thereby enabling the upper end of the stop sleeve 24 to remain flat with the upper surface of the stamping seat 12. When the die 19 is out of contact with the stop sleeve 24, the stop sleeve 24 moves upward along the movable groove 26 under the elastic force of the spring 25, and the workpiece is placed on the stamping When the seat 12 is on the upper side, the side of the workpiece is in contact with the outer surface of the stop sleeve 24. The stop sleeve 24 can play a good limiting role on the workpiece, which can not only improve the accuracy of the workpiece placement process, thereby effectively improving the stamping quality of the workpiece, but also reduce the difficulty of workpiece placement. The moving seat 27 will drive the stop sleeve 24 to move synchronously during the movement, so that the workpiece moves more smoothly, which helps to reduce the risk of the workpiece accidentally falling on the surface of the stamping seat 12, and further improve the stability of the pusher assembly during operation.

[0030] Specifically, such as Figure 4 As shown, a guide assembly is provided on the outside of the movable seat 27, and the guide assembly includes a notch 34 opened on the outer surface of the front end of the movable seat 27, and an extrusion plate 35 is fixedly connected to the inner surface of the notch 34. The extrusion plate 35 is made of elastic material, and a moving block 36 is fixedly connected to the end of the extrusion plate 35 away from the movable seat 27. The moving block 36 is located inside the movable groove 32 and is slidably connected to the inner surface of the movable groove 32.

[0031] By adopting the above technical solution, when the pusher assembly is working, in order to further reduce the difficulty of removing the stamped parts, a guide assembly is set. The notch 34 opened on the surface of the movable seat 27 is used to fix and support the extrusion plate 35. The extrusion plate 35 is arc-shaped, and its upper end is higher than the upper surface of the movable seat 27. After the workpiece is placed on the upper surface of the movable seat 27, a certain gap will be formed between the workpiece and the stamping seat 12 under the lifting action of the extrusion plate 35, so that the movable seat 27 can drive the workpiece to move smoothly. During the movement, the movable seat 27 will drive the moving block 36 to move synchronously inside the moving groove 32 through the extrusion plate 35. During the stamping process, the die 19 has a good contact with the workpiece. When pressing downward, the extrusion plate 35 will bend in the opposite direction, so that the lower end of the workpiece contacts the upper surface of the moving seat 27 for stamping. After the stamping is completed, when the moving seat 27 drives the workpiece to be pushed outward, the moving seat 27 drives the moving block 36 to move in the opposite direction through the extrusion plate 35. When the moving block 36 contacts the inside of the moving groove 32, as the moving seat 27 continues to move, the extrusion plate 35 will bend and deform upward, so that the front end of the workpiece can be lifted upward, so that a certain gap appears between the workpiece and the extrusion plate 35, so that the operator can better grasp the workpiece, thereby further reducing the difficulty of removing the workpiece, which helps to improve the convenience during the operation of the stamping machine.

[0032] Specifically, such as Figure 4 As shown, a lubrication assembly is provided on the lower side of the movable seat 27, and the lubrication assembly includes a liquid storage chamber 33 embedded in the interior of the movable seat 27, and an injection hole 41 is provided on the outer surface of the front end of the movable seat 27. The injection hole 41 is communicated with the interior of the liquid storage chamber 33, and a liquid absorbent cotton 38 is fixedly connected to the lower end of the inner surface of the liquid storage chamber 33. A contact cotton 39 is fixedly connected to the outer surface of the lower end of the liquid absorbent cotton 38, and the lower end of the contact cotton 39 is in sliding contact with the inner surface of the movable groove 32. The contact cotton 39 is made of wear-resistant elastic material.

[0033] By adopting the above technical solution, an appropriate amount of lubricating liquid is injected into the liquid storage chamber 33 through the injection hole 41, and the absorbent cotton 38 inside the liquid storage chamber 33 can fully absorb the lubricating liquid. The absorbent cotton 38 transfers the lubricating liquid to the contact cotton 39. During the sliding of the movable seat 27 inside the movable groove 32, the contact cotton 39 will slide in contact with the inside of the movable groove 32, so that the lubricating liquid can be evenly applied to the inner wall of the movable groove 32 through the contact cotton 39, thereby effectively reducing the friction of the movable seat 27 during the sliding process inside the movable groove 32, making the sliding of the movable seat 27 smoother, and further improving the stability of the pushing assembly during operation.

[0034] Specifically, such as Figure 4 As shown, a blowing assembly is provided inside the slide 29, and the blowing assembly includes a capsule 37 fixedly connected to the outer surface of the slide 30, and the end of the capsule 37 away from the slide 30 is fixedly connected to the inner surface of the slide 29, and an air inlet 20 is embedded inside the stamping seat 12.

[0035] The air inlet 20 extends to the front side of the stamping seat 12 , and an air outlet 40 is embedded inside the sliding seat 30 and the connecting block 31 . The upper end of the air outlet 40 extends to the outside of the moving seat 27 , and a one-way valve is provided inside the air inlet 20 .

[0036] By adopting the above technical solution, when the slide 30 slides in the slide groove 29 toward the side away from the movable rod 21, the slide 30 cooperates with the slide groove 29 to squeeze the sac 37, and the gas inside the sac 37 enters the air outlet 40 under the action of pressure, and then the gas is discharged from the rear end of the movable seat 27. The residual iron filings and foreign matter inside the movable groove 32 are blown and cleaned by the ejected gas to reduce the residual impurities inside the movable groove 32 and reduce the probability of impurities causing jamming of the movable seat 27, thereby further improving the smoothness of the reciprocating motion of the movable seat 27. When the slide 30 moves toward the side close to the movable rod 21, the slide 30 will stretch the sac 37. At this time, external gas is injected into the sac 37 through the air inlet 20, so that the sac 37 continues to inflate and expand. A one-way valve is provided inside the air inlet 20 and the air outlet 40 to ensure one-way flow of gas.

[0037] Working principle: During operation, the die 19 is mounted on the lower side of the pressing plate 15 through the locating pin 17, and the workpiece is placed on the upper side of the stamping seat 12. The hydraulic rod 18 drives the die 19 to move downward synchronously through the movable frame 14, and the stop sleeve 24 can play a good limiting role on the workpiece. The die 19 cooperates with the stamping seat 12 to stamp and shape the workpiece, and the middle part of the traction plate 28 is pushed downward by the movable rod 21, so that the traction plate 28 is bent and deformed downward. After the workpiece is stamped, the slide 30 drives the moving seat 27 to move in the opposite direction through the connecting block 31, and the stamped workpiece can be taken out from the lower side of the die 19 through the moving seat 27. The moving seat 27 drives the moving block 36 to move in the opposite direction through the extrusion plate 35. When the moving block 36 contacts the inside of the moving groove 32, the extrusion plate 35 will bend and deform upward, so that the workpiece can be The front end is lifted upward, so that a certain gap appears between the workpiece and the extrusion plate 35, so that the operator can better grasp the workpiece. The absorbent cotton 38 inside the liquid storage chamber 33 can fully absorb the lubricating liquid, and the absorbent cotton 38 transfers the lubricating liquid to the contact cotton 39, and the lubricating liquid is evenly applied to the inner wall of the movable groove 32 through the contact cotton 39, thereby effectively reducing the friction of the movable seat 27 during the sliding process inside the movable groove 32. The slide 30 cooperates with the slide 29 to squeeze the capsule 37, and the gas inside the capsule 37 enters the air outlet 40 under the action of pressure. The residual iron filings and foreign matter inside the movable groove 32 are blown and cleaned by the ejected gas to reduce the residual impurities inside the movable groove 32 and reduce the probability of impurities causing jamming of the movable seat 27, thereby further improving the smoothness of the reciprocating motion of the movable seat 27.
