[0022] 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.

[0023] Example 1 Reference Figures 1-4 This is the first embodiment of the present invention, which provides a metal product hot stamping device, comprising: Support 1; The combined mechanism 2 is located at the bottom of the inner cavity of the support base 1. The combined mechanism 2 includes a U-shaped plate 201 installed at the bottom of the inner cavity of the support base 1. A sliding plate 202 adapted to the U-shaped plate 201 is movably installed at the bottom of the inner cavity of the support base 1. Slider 204 is installed on both sides of the sliding plate 202. A telescopic cylinder 203 adapted to the sliding plate 202 is installed on one side of the U-shaped plate 201. Mold plates 206 are symmetrically installed on the opposite side of the sliding plate 202 and the U-shaped plate 201. Limiting strips 205 are symmetrically installed on the outer surface of the mold plates 206.

[0024] like Figure 2 As shown, in this embodiment, the inner surface of the U-shaped plate 201 is symmetrically provided with grooves adapted to the slider 204. The slider 204 is slidably connected inside the grooves. The U-shaped plate 201 and the slide plate 202 are both provided with arc-shaped grooves adapted to the mold plate 206 on opposite sides. The mold plate 206 is located inside the arc-shaped groove. The slide plate 202 is connected to the output end of the telescopic cylinder 203. When the telescopic cylinder 203 pushes the slide plate 202 in the opposite direction to the U-shaped plate 201, the mold plate 206 on one side of the U-shaped plate 201 and the mold plate 206 on the side of the slide plate 202 can be combined, so that the two mold plates 206 form a complete mold body on one side, which facilitates the subsequent demolding operation.

[0025] like Figure 4As shown, in this embodiment, the combined mechanism 2 also includes bolts 209 that are evenly distributed and symmetrically installed inside the U-shaped plate 201 and the slide plate 202. The outer surface of the bolts 209 is connected to square nuts 207 by thread. A first spring 208 is installed on the top of the U-shaped plate 201. A pressure block 210 is movably installed on the outer surface of the bolts 209. When the bolts 209 are rotated, the square nuts 207 can be moved upward, and the first spring 208 can be compressed and deformed. Under the interaction of the square nuts 207 and the bolts 209, one end of the pressure block 210 is pressed onto the mold plate 206. Under the action of multiple pressure blocks 210, the corresponding mold plate 206 is subjected to downward pressure, and the mold plate 206 is fixed.

[0026] like Figure 4 As shown, in this embodiment, both the U-shaped plate 201 and the sliding plate 202 have symmetrically provided square grooves that are adapted to the square nuts 207. The square nuts 207 are slidably connected inside the square grooves. The first spring 208 is located outside the bolt 209. The top of the mold plate 206 has a semi-circular groove that is adapted to the pressure block 210. The pressure block 210 is movably engaged inside the semi-circular groove. The pressure block 210 is inserted into the semi-circular groove at the top of the mold plate 206. Through the cooperation of the bolt 209 and the square nut 207, the pressure block 210 is pressed against the top of the semi-circular groove. At the same time, under the action of the first spring 208, when the bolt 209 is removed, an upward pushing force is provided to the pressure block 210, which facilitates the removal of the pressure block 210.

[0027] Furthermore, using a wrench, several bolts 209 are loosened sequentially. The bolts 209 rotate inside the square nut 207. At this time, under the action of the corresponding first spring 208, an upward pushing force is applied to the pressure block 210, causing it to slowly move upward from the top of the mold plate 206. The square nut 207 remains at the top of the square groove of the pressure block 210. After the pressure block 210 is completely detached from the mold plate 206, a force is applied to the pressure block 210 to rotate it around the bolts 209, causing the pressure block 210 to rotate ninety degrees, thus loosening several bolts 209. After all blocks 210 are rotated 90 degrees, the two mold plates 206 are pulled upward from the corresponding U-shaped plates 201 and slide plates 202 respectively. At this time, the mold plates 206 drive the two limit bars 205 to move upward. After removing the mold plates 206, replace them with mold plates 206 that match the workpiece. Rotate the multiple pressure blocks 210 in the opposite direction to the initial position. Use a wrench to tighten the multiple bolts 209 respectively. Press the processing pressure block 210 on the top of the corresponding mold plate 206 to complete the replacement of the mold plate 206.

[0028] Example 2 Reference Figure 5 and Figure 6This is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. The insertion mechanism 3 is disposed at the top of the inner cavity of the support base 1. The insertion mechanism 3 includes a hollow plate 302 installed at the top of the inner cavity of the support base 1. A punching head 303 is movably installed inside the hollow plate 302. A horizontal pin 306 adapted to the punching head 303 is movably inserted inside the hollow plate 302. A vertical pin 307 is installed inside the horizontal pin 306.

[0029] like Figure 5 As shown, in this embodiment, a stamping cylinder 301 adapted to the hollow plate 302 is installed at the top center of the support base 1. The center of the hollow plate 302 is connected to the output end of the stamping cylinder 301. A spring piece 308 adapted to the horizontal pin 306 is symmetrically installed at the bottom of the vertical pin 307. A push ring 305 is movably installed on the outer surface of the output end of the stamping head 303. A second spring 304 is provided on the top of the push ring 305. Under the action of the two spring pieces 308, after the vertical pin 307 is inserted into the horizontal pin 306, the spring piece 308 is stuck on the outside of the horizontal pin 306 to prevent the vertical pin 307 from falling out of the horizontal pin 306.

[0030] like Figure 6 As shown, in this embodiment, the other end of the second spring 304 is fixedly connected to the punch head 303. The vertical pin 307 is located on one side of the hollow plate 302. The hollow plate 302 has symmetrical arc-shaped holes on both sides that are adapted to the horizontal pin 306. The punch head 303 has symmetrical arc-shaped slots on both sides that are adapted to the arc-shaped holes. The horizontal pin 306 is slidably connected inside the arc-shaped holes and arc-shaped slots. Under the action of the second spring 304, after the punch head 303 has finished punching the workpiece, the second spring 304 applies a downward pushing force to the push ring 305. The push ring 305 pushes the punched workpiece downward to prevent the workpiece from sticking to the output end of the punch head 303. Under the action of the horizontal pin 306, the punch head 303 can be stably fixed inside the hollow plate 302.

[0031] Further, manually pull the vertical pin 307 vertically upwards, causing the two spring pieces 308 to slide off the outer surface of the horizontal pin 306. After the vertical pin 307 moves out of the horizontal pin 306, pull the horizontal pin 306 horizontally outwards, completely disengaging it from the hollow plate 302. Then, remove the stamping head 303 downwards from the hollow plate 302 and replace it with a stamping head 303 that matches the two mold plates 206. Insert the matching stamping head 303 into... Inside the hollow plate 302, the horizontal pin 306 is inserted horizontally into the hollow plate 302 and the punch head 303. Then, the vertical pin 307 is inserted into the horizontal pin 306, and the spring piece 308 is pressed down and locked on the outside of the horizontal pin 306 to complete the replacement of the punch head 303. The operation of the punch cylinder 301 is controlled. The output end of the punch cylinder 301 pushes the punch head 303 to the opposite side of the two mold plates 206 through the hollow plate 302 for punching.

[0032] Working principle: The device is connected to an external power supply and controller using a wiring harness. The telescopic cylinder 203 is controlled to operate. The output end of the telescopic cylinder 203 pushes the slide plate 202 within the U-shaped plate 201. The slide plate 202 drives a mold plate 206 to move towards the mold plate 206 located within the U-shaped plate 201. After the two mold plates 206 are fully engaged, high-temperature metal is placed in the cavity formed by the two mold plates 206. The stamping cylinder 301 is then controlled to operate. The output end of the stamping cylinder 301 pushes the stamping head 303 towards the center of the two mold plates 206 through the hollow plate 302. The stamping head 303 then stamps the high-temperature metal to the desired shape. The stamping cylinder 301 is then controlled to reverse direction, moving the stamping head 303 from the two mold plates... Move out of 206, control the telescopic cylinder 203 to run in reverse, the output end of the telescopic cylinder 203 pulls the slide plate 202 in the opposite direction, the stamped metal product falls downward and flows out from one side of the support seat 1. When it is necessary to stamp metal products of different shapes, use a wrench to loosen several bolts 209 in sequence. The bolts 209 rotate inside the square nut 207. At this time, under the action of the corresponding first spring 208, an upward pushing force is applied to the pressure block 210, so that the pressure block 210 slowly moves upward from the top of the mold plate 206. The square nut 207 is always located at the top of the square groove of the pressure block 210. After the pressure block 210 is completely separated from the mold plate 206, apply a force to the pressure block 210 to rotate around the bolt 209, rotate the pressure block 210 ninety degrees, and several pressure blocks After rotating 210 by 90 degrees, pull the two mold plates 206 upward from the corresponding U-shaped plates 201 and slide plates 202 respectively. At this time, the mold plates 206 drive the two limit strips 205 to move upward. After removing the mold plates 206, replace them with mold plates 206 that match the workpiece. Rotate the multiple pressure blocks 210 in the opposite direction to the initial position. Use a wrench to tighten the multiple bolts 209 respectively. Press the processing pressure block 210 onto the top of the corresponding mold plate 206 to complete the replacement of the mold plate 206. Then, replace the matching punch head 303 according to the installed mold plate 206. Manually pull the vertical pin 307 vertically upward to make the two spring pieces 308 slide from the outer surface of the horizontal pin 306. Wait until the vertical pin 307 is pulled out of the horizontal pin 306. After removal, pull the horizontal pin 306 outward horizontally to completely disengage it from the hollow plate 302. Then, remove the punch head 303 downward from the hollow plate 302 and replace it with a punch head 303 that matches the two mold plates 206. Insert the matching punch head 303 into the hollow plate 302. Insert the horizontal pin 306 horizontally into the hollow plate 302 and the punch head 303. Then, insert the vertical pin 307 into the horizontal pin 306. While pressing the spring piece 308 downward, it is locked on the outside of the horizontal pin 306, completing the replacement of the punch head 303. Control the operation of the punch cylinder 301. The output end of the punch cylinder 301 pushes the punch head 303 towards the opposite side of the two mold plates 206 through the hollow plate 302 for punching.
