[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a stamping die for processing automotive frame tubular parts includes a vertical plate 101 fixedly connected to the surface of the stamping die 1; a first cylinder 102 fixedly connected to the side of the vertical plate 101; a horizontal plate 104 fixedly connected to the output end of the first cylinder 102; a sponge 105 fixedly connected to the side wall of the horizontal plate 104; a fixing plate 106 fixedly connected to the surface of the stamping die 1; a lower die 111 fixedly connected to the bottom surface of the fixing plate 106; the inner wall of the sponge 105 closely adhering to the surface of the lower die 111; a second cylinder 107 fixedly connected to the top surface of the fixing plate 106; an upper die 109 fixedly connected to the output end of the second cylinder 107; the upper die 109 and the lower die 111 are correspondingly arranged; a cylinder 110 fixedly connected to the inner wall of the upper die 109; and a circular groove 112 formed on the surface of the lower die 111. The cylinder 110 and the groove 112 are correspondingly arranged. During operation, the second cylinder 107 is activated to move the rod, which drives the upper mold 109 to move downward to pressurize the pipe and complete the stamping. The first cylinder 102 is activated to exert a forward force on the horizontal plate 104. As a result, the first cylinder 102 pushes the horizontal plate 104, causing the sponge 105 on the side wall of the horizontal plate 104 to move forward and closely adhere to the surface of the lower mold 111. This wipes away the debris and stains remaining on the surface of the lower mold 111 after the stamping process. Then, the first cylinder 102 is activated again to move the horizontal plate 104 backward to the original position for the next stamping. Thus, after completing one stamping process, the lower mold 111 is wiped clean of any remaining substances. During the next stamping, the waste residue from the previous stamping will not damage the pipe to be stamped.
[0026] like Figures 1 to 2 As shown, a spring 2 is fixedly connected inside the horizontal plate 104; the end of the spring 2 is fixedly connected to the side wall of the sponge 105; the spring 2 and the sponge 105 are glued together; during operation, after the stamping process is completed, the second cylinder 107 is started to drive the upper mold 109 to move downwards. When the inner wall of the upper mold 109 moves to the surface of the sponge 105, it stops moving. At this time, the first cylinder 102 is started to push the sponge 105 forward, cleaning the surface of the lower mold 111 and the inner wall of the upper mold 109 at the same time. When the spring 2 on the side wall of the sponge 105 moves... When the sponge 105 moves to the middle of the pair of cylinders 110, the spring 2 on the side wall of the sponge 105 will be squeezed by the protruding cylinder 110, thereby generating elastic force to push the other side wall of the sponge 105 to contact the inner wall of the pair of cylinders 110, thus wiping the inner wall of the cylinder 110. In this way, the lower mold 111 and the upper mold 109 can be cleaned at the same time. The spring 2 on the side wall of the sponge 105 allows the sponge 105 to clean the inside of the cylinder 110, so that there will be no residual debris from the previous stamping on the cylinder 110 during the next stamping process, and it will not affect the next stamping.
[0027] like Figure 5 As shown, a nozzle 3 is fixedly connected to the end of the side wall of the horizontal plate 104; the nozzle 3 is inclined; a water pipe 301 is fixedly connected to the other side of the nozzle 3; during operation, before starting the first cylinder 102, the water pipe 301 is connected to the water pump, and the water flows through the water pipe 301 to the nozzle 3, and is sprayed onto the sponge 105 through the nozzle 3, wetting the sponge 105. Then, the sponge 105 is started to wipe the lower mold 111 and the upper mold 109 to remove the residue on them; thus, the sponge 105 is wetted and then wipes the lower mold 111 and the upper mold 109 to firmly absorb the residual waste in the water, so that the waste cannot fly away.
[0028] like Figure 1 As shown, a hot air blower 4 is fixedly attached to the surface of the stamping die 1; the hot air blower 4 is on one side of the fixed plate 106; the air outlet of the hot air blower 4 is directly facing the lower die 111 and the upper die 109; during operation, after the sponge 105 has completed the cleaning of the lower die 111 and the upper die 109, the power is connected and the hot air blown from the surface of the hot air blower 4 is started, blowing away the residual moisture on the lower die 111 and the upper die 109; thus, the residual moisture on the surface of the lower die 111 and the upper die 109 is dried so that the residual wastewater will not affect the next stamping of the pipe.
[0029] like Figures 3 to 4 As shown, the stamping die assembly 1 has a funnel 5 inside; a ring 502 is fixedly connected to the end of the funnel 5; a filter plate 501 is provided at the bottom of the funnel 5; the ring 502 is fixedly connected to the inner wall of the stamping die assembly 1; the funnel 5 is fixedly connected to the inner wall of the stamping die assembly 1; a drainage hole 503 is provided at the bottom of the side wall of the stamping die assembly 1; a circular groove 112 penetrates the surface of the stamping die assembly 1; the circular groove 112 communicates with the funnel 5; during operation, the waste material remaining after stamping passes through the circular groove. 112 falls directly into the funnel 5. While the sponge 105 is cleaning, the waste and wastewater from the lower mold 111 and the upper mold 109 are pushed into a pair of circular grooves 112. The wastewater falls through the circular grooves 112 to the bottom of the funnel 5. The wastewater is filtered by the filter plate 501 at the bottom of the funnel 5, leaving the waste inside the funnel 5. The wastewater is discharged through the drain hole 503. This process collects and discharges the impurities cleaned by the sponge 105, ensuring that the waste material after stamping does not remain in the circular grooves 112 and eliminating the need to clean the circular grooves 112.
[0030] like Figure 4As shown, the funnel 5 has an external thread 6 on its end surface; the inner wall of the ring 502 has an internal thread 601; the external thread 6 and the internal thread 601 are correspondingly arranged; the other side of the stamping die assembly 1 has a cabinet door 602; during operation, after the sponge 105 cleans the upper die 109 and the lower die 111, and after filtering by the filter plate 501, the handle is pulled to open the cabinet door 602, the funnel 5 is rotated, and the funnel 5 is disassembled from the ring 502, thereby completing the cleaning of the waste in the funnel 5; thus, the funnel 5 becomes a detachable device, which facilitates the collection and cleaning of waste.
[0031] Working principle: By activating the second cylinder 107 to move the rod, the rod drives the upper mold 109 downward to pressurize the pipe and complete the stamping. Activating the first cylinder 102 exerts a forward force on the horizontal plate 104, thereby pushing the horizontal plate 104 and causing the sponge 105 on the side wall of the horizontal plate 104 to move forward, closely adhering to the surface of the lower mold 111, wiping away any debris and stains remaining on the surface of the lower mold 111 after the stamping process. Then, the first cylinder 102 is activated again to move the horizontal plate 104 backward to its original position for the next stamping cycle. After the stamping process is completed, the second cylinder 107 is activated to drive the upper mold 109 downward. At the same time, the first cylinder 102 is activated to push the sponge 105 forward, cleaning the surface of the lower mold 111 and the inner wall of the upper mold 109. When the spring 2 on the side wall of the sponge 105 moves to the middle of the pair of cylinders 110, the spring 2 on the side wall of the sponge 105 will be squeezed by the protruding cylinder 110, thereby generating elastic force to push the other side wall of the sponge 105 to contact the inner wall of the pair of cylinders 110, thus wiping the inner wall of the cylinders 110; when the first cylinder 102 is activated... First, connect the water pipe 301 to the water pump. Water flows through the water pipe 301 to the nozzle 3, and is sprayed onto the sponge 105, wetting it. Then, the sponge 105 is activated to wipe the lower mold 111 and the upper mold 109, removing any residue. After the sponge 105 has finished cleaning the lower mold 111 and the upper mold 109, connect the power supply and start the hot air blower 4. Hot air blown from the surface of the hot air blower 4 is directed towards the lower mold 111 and the upper mold 109 to dry any remaining moisture. Any remaining waste material from the stamping process falls directly into the circular groove 112. Inside the funnel 5, while the sponge 105 is cleaning, the waste and wastewater from the lower mold 111 and upper mold 109 are pushed into a pair of circular grooves 112. The wastewater falls through the circular grooves 112 to the bottom of the funnel 5, where it is filtered by the filter plate 501 at the bottom of the funnel 5. The waste remains inside the funnel 5, and the wastewater is discharged through the drain hole 503. After the sponge 105 has finished cleaning the upper mold 109 and lower mold 111, and after filtration by the filter plate 501, the handle is pulled to open the cabinet door 602, and the funnel 5 is rotated to disassemble it from the ring 502, thus completing the cleaning of the waste inside the funnel 5.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
