Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology, specifically a stamping structure for a stamping press used in automotive parts production. Background Technology

[0002] Automotive parts are the basic units that make up a complete vehicle, including the various components of the body, chassis, engine, transmission system, suspension system, braking system, steering system, etc. Each part plays an irreplaceable role in the operation of the car, ensuring its performance, safety and durability. Stamping is a very common and important step in manufacturing these automotive parts. A stamping press is a piece of equipment specially used for processing sheet metal. By applying strong pressure to the sheet metal, it is deformed into the required shape to manufacture various automotive parts. Some special stamping presses can also punch holes while stamping. This is achieved through special mold structures. These special structures are usually protrusions corresponding to the shape of the opening.

[0003] Current stamping presses require greater pressure to punch holes in metal sheet workpieces compared to ordinary stamping. Prolonged operation can easily cause deformation or even damage to the protrusions on the punched part of the die due to stress. Furthermore, the enormous pressure generated during stamping can easily damage the stamping press itself. Therefore, we propose a stamping structure for a stamping press used in the production of automotive parts. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The present invention allows for the replacement of the upper and lower dies, enabling the use of a stamping device to stamp workpieces of different shapes. Simultaneously, it can pre-stamp annular grooves on the workpiece at the locations where holes are required using a punching ring, thus eliminating the need for repositioning during punching and preventing deviations in the punching position.

[0017] 2. This invention involves coating the groove with a film during stamping, creating a sealed cavity between the groove and the film. Then, an etching solution is injected into the cavity through an injection device to completely etch the groove into a complete mounting hole. This allows mounting holes to be made on thicker workpieces by combining punching and etching. Compared with direct punching, this method reduces mold wear and lowers the pressure requirements for stamping.

[0018] 3. The rinsing device in this invention can use water pressure to directly separate the film on the etched workpiece, while simultaneously flushing away waste materials such as etching solution. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Depend on Figure 1-8 The first embodiment of the present invention is provided, including a workbench 1, with support columns 2 arranged on both sides of the top of the workbench 1, and a stamping device 3 arranged between the two support columns 2. The stamping device 3 includes an upper die 31, and a lower die 32 arranged below the upper die 31. The lower die 32 is detachably installed on the top of the workbench 1. A film feeding device 4 is also installed on the top of the workbench 1. A conveying device 5 and a clamping device 6 are arranged on the front side of the workbench 1. The clamping device 6 is used to move the workpiece between the stamping device 3 and the conveying device 5. A waste collection device 7 is arranged on the side of the conveying device 5 away from the workbench 1. A liquid injection device is installed above the waste collection device 7 through a moving mechanism.

[0033] The stamping device 3 also includes a crossbeam 33. Cylinders 34 are respectively provided at the bottom of the crossbeam 33 near the inner side of the two support columns 2. The telescopic ends of the two cylinders 34 face and are connected to the first mounting base 35. The two ends of the first mounting base 35 are slidably connected to the inner sidewalls of the two support columns 2. The bottom of the first mounting base 35 is detachably provided with an upper die 31 through a connecting column 36. The upper die 31 is provided with a number of punching protrusions 37 for pressing grooves on the surface of the workpiece. A heating ring 38 is provided circumferentially on the outer side of the punching protrusions 37. The lower die 32 is provided with punching protrusions 37 that match the number and position of the upper die 31.

[0034] The film feeding device 4 includes a first support frame 41 and a second support frame 42 respectively disposed on both sides of the lower mold 32. The bottom of the first support frame 41 and the second support frame 42 are fixedly connected to the top wall of the worktable 1. The top of the second support frame 41 is rotatably connected to a film tube 43 and a guide tube 44 respectively through a connecting shaft. The middle of the first support frame 41 is also rotatably connected to a film roll 45. The film roll 45 is driven by the output end of a first servo motor 46. The first servo motor 46 is installed on the outer side wall of the first support frame 41. The film on the film tube 43 is pulled out and can bypass the outside of the guide tube 44 and be turned before being led out and fixed on the film roll 45, forming a two-layer film distribution between the upper mold 31 and the lower mold 32. After one stamping is completed, the first servo motor 46 drives the film roll 45 to rotate, and a part of the film is wound up. The complete film part is placed in the stamping area between the upper mold 31 and the lower mold 32.

[0035] The injection device includes a second telescopic rod 91, with a syringe 92 mounted on the telescopic end of the second telescopic rod 91. The input end of the syringe 92 is connected to a liquid preparation tank 94 via a first connecting pipe 93. The injection device is installed on the moving end of the moving mechanism. The syringe 92 is used to pierce the film and inject etching solution into the groove. In use, the workpiece conveyed by the conveying device 5 is first clamped between the upper mold 31 and the lower mold 32 by the clamping device 6, specifically between the upper and lower film layers. After the clamping device 6 releases the workpiece, it moves away, and the upper mold 31 descends. The workpiece is stamped into a specific shape, and grooves are pressed into the workpiece through the punching ring 37. At the same time, a thin film is pressed into the groove. The film is heated and melted by the heating ring 38. Due to the low temperature of the workpiece, the film can adhere to the edge of the groove, forming a closed cavity between the groove and the film. The clamping device 6 clamps the workpiece and transfers it to the waste collection device 7. A certain amount of etching solution is injected into the groove by piercing the film through the liquid injection device. The etching solution corrodes the workpiece along the groove, completely penetrating the groove and forming a mounting hole of a specific size on the workpiece.

[0036] The clamping device 6 includes a first telescopic rod 61. A second servo motor 63 is mounted on the telescopic end of the first telescopic rod 61 via a second mounting base 62. A first horizontal arm 64 is mounted on the output end of the second servo motor 63. A second horizontal arm 66 is connected to the bottom of the first horizontal arm 64 via a first slide rail structure 65. The second horizontal arm 66 can move along the length of the first horizontal arm 64 via the first slide rail structure 65. A third servo motor 67 is located at the bottom of the first horizontal arm 64. A first gear is located at the output end of the third servo motor 67. A first rack 68 is located on one side of the second horizontal arm 66, and the first rack 68 and the first gear mesh. A fourth servo motor 69 is located at the distal end of the first horizontal arm 64. The output end of the fourth servo motor 69 faces downwards and is connected to a support plate 610. A suction cup 611 is provided at the bottom, and the suction cup 611 is connected to a vacuum generator 613 through a second connecting pipe 612. A control valve is provided on the second connecting pipe 612. When the workpiece needs to be moved, the height is raised or lowered by extending or retracting the first telescopic rod 61. The first horizontal arm 64 is driven by the second servo motor 63 to adjust its horizontal angle. Then, the third servo motor 67 rotates, and the first gear meshes with the first rack 68 to drive the second horizontal arm 66 to extend or retract. Then, the fourth servo motor 69 drives the support plate 610 to rotate, so that the suction cup 611 is aligned with and in contact with the workpiece. The vacuum generator 613 works, using air pressure to adsorb and fix the workpiece under the suction cup 611, achieving stable clamping. The workpiece can be released by adjusting the balance air pressure through the control valve.

[0037] The waste collection device 7 includes a waste bin 71, a storage mesh frame 72 is provided inside the waste bin 71, the surface of the storage mesh frame 72 and the inner wall of the waste bin 71 are both provided with anti-corrosion coating, a discharge pipe 73 is provided on the side wall of the waste bin 71, and a flushing device is installed on the top of the waste bin 71 through a moving mechanism. The water pressure released by the flushing device can separate the film on the groove of the workpiece.

[0038] The rinsing device includes a water outlet pipe 101, which is connected to a water tank 103 via a third connecting pipe 102. A pressure pump 104 is installed inside the water tank 103. The rinsing device and the liquid injection device are installed together at the moving end of the moving mechanism. The moving mechanism drives the water outlet pipe 101 to move above the membrane. The pressure pump 104 sprays water from the water tank 103 onto the membrane, thereby separating the membrane on the workpiece groove and flushing away the etching solution and waste liquid inside the membrane into the waste bin 71.

[0039] The moving mechanism includes a second slide rail structure 81 set on top of the waste collection device 7, a third slide rail structure 82 mounted on the second slide rail structure 81, a slide seat 83 set on the third slide rail structure 82, and a flushing device and a liquid injection device installed at the bottom of the slide seat 83.

[0040] A hot air blower 74 is provided on the side wall of the waste bin 71. The hot air blower 74 has a rectangular air outlet 75. The air outlet 75 is connected to the inner wall of the waste bin 71 and faces the inner side of the waste bin 71. The clamping device 6 places the workpiece on the storage rack 72. The air outlet 75 faces the side where the workpiece is placed. The hot air generated by the hot air blower 74 can be blown onto the workpiece through the air outlet 75 to dry the moisture on the cleaned workpiece.

[0041] The film is a transparent and elastic polyolefin hot melt film. The syringe 92 punctures the film to create a pinhole. The film can elastically seal the pinhole to prevent the etching solution from leaking out through the pinhole and to prevent it from breaking during water rinsing. It can be separated from the trench as a whole.

[0042] like Figure 9 and Figure 10In the second embodiment shown, a transmission mechanism 11 is provided between the stamping device 3 and the film feeding device 4. The transmission mechanism 11 includes a one-way bearing 111. The shaft end of the film roll 45 rotatably passes through the first support frame 41 and is fixedly sleeved with the one-way bearing 111. A second gear 112 is fixedly sleeved on the one-way bearing 111. A second rack 114 is installed on the side wall of the first mounting base 35 through an adjusting bolt 113. The second rack 114 has a slot, and the adjusting bolt 113 can pass through the slot to lock the second rack 114 on the side wall of the first mounting base 35. Since the installation direction of the one-way bearing 111 allows the stamping device 3 to rotate through the second rack 114 to drive the second gear 112 to mesh when it is lifted, the one-way bearing 111 is in a locked state at this time. This allows the film roll 45 to rotate, winding up a portion of the film after stamping and coating, placing the complete film portion in the stamping area between the upper die 31 and the lower die 32. When the stamping device 3 presses down, the second rack 114 drives the second gear 112 to rotate. Since the one-way bearing 111 is in an active state at this time, the second gear 112 rotates around the shaft end of the film roll 45 through the one-way bearing 111, and does not drive the film roll 45 to rotate. Thus, the complete film can be sent into the stamping area only after a single stamping and coating is completed. The length of the second rack 114 is adjusted and locked by setting the adjusting bolt 113 and the strip hole, thereby adjusting the transmission stroke between the second rack 114 and the second gear 112 to correspond to the width stroke of the workpiece, so as to adapt to workpieces of different sizes.

[0043] Working principle: During operation, firstly, the matching upper die 31 and lower die 32 are installed according to the shape to be stamped out of the workpiece. Then, the workpiece conveyed by the conveying device 5 is clamped between the upper die 31 and lower die 32 by the clamping device 6, specifically between the upper and lower thin films. After the clamping device 6 releases the workpiece and moves away, the telescopic ends of the two cylinders 34 extend synchronously, thereby driving the upper die 31 to descend and stamp the workpiece into a specific shape. Grooves are pressed into the workpiece by the punching ring 37, and the thin film is pressed into the groove. The heating ring 38 heats and melts the thin film. Due to the low temperature of the workpiece, the thin film can adhere to the edge of the groove, forming a closed cavity between the groove and the thin film. The cylinders 34 retract. The upper die 31 is lifted, completing one stamping operation. The clamping device 6 clamps the workpiece and transfers it to the scrap collection device 7. The clamping device 6 can continue to move the next workpiece into the stamping area for stamping operation. At the same time, the liquid injection device is moved to the groove of the workpiece on the scrap collection device 7 by the moving mechanism. The second telescopic rod 91 extends to drive the syringe 92 to pierce the film and inject a certain amount of etching solution into the groove. The etching solution corrodes the workpiece along the groove, just enough to completely penetrate the groove, thereby forming a mounting hole of a specific size on the workpiece. Then, water is sprayed onto the film by the rinsing device to separate the film on the workpiece groove. In particular, the etching and cleaning operation does not affect the continuity of the stamping operation.
