Description

Technical Field

[0001] This utility model relates to the field of punching tooling technology, specifically to punching tooling for door panels. Background Technology

[0002] The upper trim panel, or simply upper trim, covers the inner door panel. In addition to decorating the door, it also provides functions such as convenient door opening and closing, elbow and wrist support, sound insulation and vibration absorption, dust and water protection, and protection of the human body in the event of a vehicle collision. When manufacturing the upper trim panel, the raw materials of the upper trim panel need to be cut using a punching tool.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] 1. The door panel is equipped with a punching fixture. When cutting the sheet metal, the part of the sheet metal to be cut is placed under the punching head. Then, the first motor is started to drive the bidirectional screw to rotate, causing the first connecting plates on both sides installed on the bidirectional screw to move closer together with the rotation of the bidirectional screw. This causes the positioning plates on both sides to move closer together and clamp the sides of the sheet metal. Then, the second motor is started to drive the threaded rods on both sides to rotate, causing the second connecting plates installed on the threaded rods on both sides to descend with the rotation of the threaded rods on both sides. This causes the pressure limiting plates installed on the second connecting plates on both sides to descend and press down and limit the sheet metal. Then, the punching rod is started to extend, causing the punching head to descend and punch and cut the sheet metal. This can stabilize and fix the sheet metal during cutting, preventing the sheet metal from shaking or shifting when being cut by the punching head.

[0028] 2. The door panel is equipped with a punching fixture. When it is necessary to replace the punching head, the threaded screws on both sides are rotated to disconnect them from the connecting seat. Then, the threaded screws are pulled outwards, causing the moving plates on both sides to press against the return springs on both sides. This causes the fixing clips on the moving plates to release their hold on the punching head, which then moves into the mounting slots on both sides. The punching head is then removed, and a new punching head is installed in the connecting seat. The threaded pull rods on both sides are then released, causing the pressed return springs to extend and push the moving plates on both sides to move. The fixing clips on the moving plates on both sides then insert into the punching head, securing it. Finally, the threaded pull rods on both sides are rotated to connect with the connecting seat. This significantly simplifies the disassembly and installation process of the punching head, making it easier to replace. Attached Figure Description

It significantly simplifies the disassembly and installation process of the punching head, facilitating its replacement. Please refer to [link to relevant documentation]. Figure 1-4 It includes a base 100 and a support plate 200;

[0038] Please refer to it again. Figure 1-2The base 100 has support plates 200 fixedly connected to its top left and right sides. A receiving groove 110 is formed on the rear top side of the base 100 for installing a buffer pad 111. The buffer pad 111 is adhered to the bottom of the inner cavity of the receiving groove 110 and is used to protect the stamping cutter head 240. The base 100 is characterized by having a first motor 120 fixedly connected to its right side wall, which drives a bidirectional screw 121. The left end of the power output shaft of the first motor 120 is fixedly connected to the bidirectional screw 121, which is used to install a first connecting plate 122. The left end of the bidirectional screw 121 penetrates the base 100 and extends into its inner cavity. The outer sides of the bidirectional screw 121 are fixedly connected to a second... A connecting plate 122 is used to connect with a positioning plate 130. The first connecting plates 122 on both the left and right sides penetrate the base 100 and extend to the top of the base 100. Positioning and clamping mechanisms are provided on the left and right sides of the top of the base 100. The positioning and clamping mechanisms include a positioning plate 130, which is used to install the main structure and clamp the sides of the plate. A second motor 140 drives a threaded rod 141, which causes the second connecting plate 142 to move up and down. The second connecting plate 142 is used to install a downward pressure limiting plate 150, which limits the position of the plate. The positioning plate 130 is located via the left... The first connecting plates 122 on both sides of the right are fixedly connected to the top left and right sides of the base 100. The top of the positioning plates 130 on both sides is fixedly connected to the second motor 140. The bottom end of the power output shaft of the second motor 140 on both sides is fixedly connected to the threaded rod 141. The bottom end of the threaded rod 141 on both sides passes through the positioning plates 130 on both sides and extends into the inner cavity of the positioning plates 130. The outer side wall of the threaded rod 141 on both sides is screwed to the second connecting plate 142. The inner side wall of the second connecting plate 142 on both sides passes through the positioning plates 130 on both sides and extends into the outer side wall of the positioning plates 130 on both sides. The inner side wall of the second connecting plate 142 on both sides is fixedly connected to the lower limit plate 150. When cutting the plate, the plate is cut by... The cutting edge is placed below the stamping cutter head 240. Then, the first motor 120 is started to drive the bidirectional screw 121 to rotate, causing the first connecting plates 122 on both sides mounted on the bidirectional screw 121 to move closer together with the rotation of the bidirectional screw 121. This causes the positioning plates 130 on both sides to move closer together to clamp the two sides of the sheet metal. Then, the second motor 140 is started to drive the threaded rods 141 on both sides to rotate, causing the second connecting plates 142 mounted on the threaded rods 141 on both sides to descend with the rotation of the threaded rods 141 on both sides. This causes the pressure limiting plates 150 mounted on the second connecting plates 142 on both sides to descend and pressure limit the sheet metal. After that, the stamping rod 220 is started to extend, causing the stamping cutter head 240 to descend and stamp and cut the sheet metal.

[0039] In summary, the material can be firmly fixed during cutting to prevent it from shaking or shifting when cut by the 240 punching head.

[0040] Please refer to it again. Figure 1-4 A top plate 210 is fixedly connected between the tops of the left and right support plates 200. A stamping rod 220 is fixedly connected to the top of the top plate 210. The stamping rod 220 is used to stamp the sheet metal with a stamping cutter head 240. The bottom end of the stamping rod 220 passes through the top plate 210 and extends to the bottom of the top plate 210. A quick-release mechanism is fixedly connected to the bottom end of the stamping rod 220. The quick-release mechanism includes a connecting seat 230, which is used to install the main structure. The stamping cutter head 240, the mounting groove 250, and the mounting groove 250 are used to install the movable plate 251. The movable plate 251 is used to install the fixing tenon 252. The fixing tenon 252 is used to... The stamping cutter head 240 is fixed. A threaded pull rod 260 is used to connect the moving plate 251. A return spring 261 is used to push the moving plate 251 to return to its original position. The stamping cutter head 240 is inserted between the inner walls of the connecting seat 230. Mounting grooves 250 are opened on the left and right sides of the interior of the connecting seat 230. The moving plate 251 is slidably connected to the inner cavity of the mounting grooves 250 on both sides. Fixing tenons 252 are fixedly connected to the inner walls of the moving plates 251 on both sides. The ends of the fixing tenons 252 on both sides pass through the connecting seat 230 and extend into the interior of the stamping cutter head 240. Threaded pull rods are screwed onto the left and right sides of the outer walls of the connecting seat 230. 260, the ends of the threaded pull rods 260 on both sides pass through the connecting seat 230 and extend into the inner cavity of the mounting grooves 250 on both sides. The ends of the threaded pull rods 260 on both sides are rotatably connected to the moving plates 251 on both sides. The outer walls of the threaded pull rods 260 on both sides are fitted with return springs 261, and the return springs 261 are located in the inner cavity of the mounting grooves 250. When it is necessary to replace the stamping cutter head 240, by rotating the threaded screws on both sides, the threaded screws on both sides are disconnected from the connecting seat 230. Then, the threaded screws on both sides are pulled outward, causing the threaded screws to drive the moving plates 251 on both sides to press the return springs 261 on both sides, so that the return springs 261 installed on the moving plates 251 on both sides are pressed. The fixing latch 252 on the 1 side is removed from the stamping cutter head 240 and moved into the mounting slots 250 on both sides. Then the stamping cutter head 240 is taken out and a new stamping cutter head 240 is installed into the connecting seat 230. Then the threaded pull rods 260 on both sides are loosened, so that the compressed return springs 261 on both sides are reset and extended. The return springs 261 on both sides push the moving plates 251 on both sides to move, so that the fixing latch 252 on the moving plates 251 on both sides is inserted into the stamping cutter head 240 and fixed. Then the threaded pull rods 260 on both sides are rotated to screw the threaded pull rods 260 on both sides into the connecting seat 230. The stamping cutter head 240 is replaced on the outside.

[0041] In summary, the operation process of disassembling and installing the stamping cutter head 240 has been greatly simplified, making it easier to replace the stamping cutter head 240;

[0042] In practical use, when cutting sheet metal, those skilled in the art place the area to be cut below the stamping cutter head 240. Then, the first motor 120 is activated to drive the bidirectional screw 121 to rotate, causing the two first connecting plates 122 mounted on the bidirectional screw 121 to move closer together, thus bringing the two positioning plates 130 together to clamp the sheet metal. Next, the second motor 140 is activated to drive the two threaded rods 141 to rotate, causing the second connecting plates 142 mounted on the threaded rods 141 to descend, thus lowering the pressure limiting plates 150 mounted on the second connecting plates 142 to limit the downward pressure on the sheet metal. Then, the stamping rod 220 is extended, causing the stamping cutter head 240 to descend and stamp the sheet metal. When the stamping cutter head 240 needs to be replaced, it is done by rotating the two... The threaded screws are used to disconnect the threaded screws from the connecting seat 230. Then, the threaded screws are pulled outwards, causing the threaded screws to drive the moving plates 251 on both sides to press the return springs 261 on both sides. This causes the fixing clips 252 on the moving plates 251 to release the fixing of the stamping head 240, which moves into the mounting slots 250 on both sides. The stamping head 240 is then removed, and a new stamping head 240 is installed into the connecting seat 230. Then, the threaded pull rods 260 on both sides are released, causing the pressed return springs 261 to return and extend. This causes the return springs 261 to push the moving plates 251 on both sides to move, allowing the fixing clips 252 on the moving plates 251 to insert into the stamping head 240 and fix it in place. Then, the threaded pull rods 260 on both sides are rotated to connect with the connecting seat 230, thus replacing the stamping head 240 on the outside.
