Description

Technical Field

[0001] This utility model relates to the field of stamping machine technology, specifically to a metal stamping machine. Background Technology

[0002] In the manufacturing process of metal boxes, to improve the safety and aesthetics of the boxes, the edges and corners of the box frames are usually chamfered. The current method for chamfering the box frames involves using a stamping lathe. The box frame is fitted into the lower die of the stamping lathe, and then the stamping head drives the upper die downwards. The interaction between the upper and lower dies chamfers the edges of the box frame. However, the side lengths of the box frames vary between different batches. The stamping lathe needs to change different dies when processing different batches of box frames, resulting in poor adaptability, increased production costs, and extended production cycles.

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] like Figure 1-9 As shown, a metal stamping machine includes a stamping machine body 1, an upper die 2 mounted on the stamping head of the stamping machine body 1, and a lower die 3 mounted on the platform of the stamping machine body 1. The upper die 2 comprises two symmetrically arranged upper die cores 201, each with an inner chamfer 202 on its bottom side away from each other, and the two upper die cores 201 can be moved along a direction that approaches or moves away from each other. The lower die 3 comprises two symmetrically arranged lower die cores 301, each with an outer chamfer 302 on its top side away from each other, which cooperates with the inner chamfer 202. The two lower die cores 301 can be moved along a direction that approaches or moves away from each other. By adjusting the distance between the two upper die cores 201 of the upper die 2 and the distance between the two lower die cores 301 of the lower die 3, chamfering stamping can be performed on the edges 8 of different batches of boxes, eliminating the need for frequent changes of different molds, providing good adaptability, reducing production costs, and shortening the production cycle.

[0019] The upper die 2 includes a top plate 203 fixed to the stamping head. Two first support plates 204 are fixedly connected to the bottom of the top plate 203. A first rotating shaft 205 is rotatably connected between the two first support plates 204. The two ends of the first rotating shaft 205 are respectively provided with a forward-rotating thread section and a reverse-rotating thread section. One upper die core 201 has a forward-rotating threaded hole 206 that mates with the forward-rotating thread section, and the other upper die core 201 has a reverse-rotating threaded hole 207 that mates with the reverse-rotating thread section. The top of the upper die core 201 has two opposing convex first sliding grooves 208. The bottom of the top plate 203 is fixedly connected to a first slide rail 209 that corresponds to and slides with the first sliding grooves 208. When the first rotating shaft 205 rotates forward or reverse, the two upper die cores 201 can move along the length of the first slide rail 209. The two upper mold cores 201 can be adjusted by sliding them closer or further apart. A transmission plate 211 is fixedly connected to the bottom of the top plate 203. A first transmission rod 212 is rotatably connected to the transmission plate 211. A first bevel gear 213 is sleeved in the middle of the first rotating shaft 205. A second bevel gear 214 that meshes with the first bevel gear 213 is fixedly connected to one end of the first transmission rod 212, and a first knob 210 is fixedly connected to the other end. By turning the first knob 210 by hand, the first transmission rod 212 is driven to rotate. The first transmission rod 212 drives the first bevel gear 213 to rotate through the second bevel gear 214. The first bevel gear 213 drives the first rotating shaft 205 to rotate. A first anti-slip sleeve 215 is sleeved on the surface of the first knob 210, which has an anti-slip effect.

[0020] The lower mold 3 includes a base plate 303. Two second support plates 304 are fixedly connected to the top of the base plate 303. A second rotating shaft 305 is rotatably connected between the two second support plates 304. The connection method between the two lower mold cores 301 and the second rotating shaft 305 is the same as the connection method between the two upper mold cores 201 and the first rotating shaft 205. Two opposing limiting plates 306 are fixedly connected to the bottom of the base plate 303. A second slide rail 307 is fixedly connected to the side of the two limiting plates 306 that are close to each other. The lower mold cores 301 are provided with a second slide groove 308 that corresponds to and slides with the second slide rail 307. When the second rotating shaft 305 rotates forward or backward, the two lower mold cores 301 can slide closer or further away from each other along the length direction of the second slide rail 307, thereby adjusting the distance between the two lower mold cores 301. A second transmission rod 310 is rotatably connected to one of the limiting plates 306. A third bevel gear 311 is sleeved in the middle of the second rotating shaft 305. A fourth bevel gear 312 that meshes with the third bevel gear 311 is fixedly connected to one end of the second transmission rod 310, and a second knob 309 is fixedly connected to the other end. By turning the second knob 309 by hand, the second transmission rod 310 is driven to rotate. The second transmission rod 310 drives the third bevel gear 311 to rotate through the fourth bevel gear 312. The third bevel gear 311 drives the second rotating shaft 305. A second anti-slip sleeve 313 is sleeved on the surface of the second knob 309, which has an anti-slip effect.

[0021] The base plate 303 and the platform of the press body 1 are fixedly connected by several springs 4. The springs 4 can act as a buffer to prevent the upper mold 2 from being too forceful and damaging the lower mold 3. Two baffles 5 are fixedly connected to the top of the platform of the press body 1, which are symmetrically arranged with respect to the base plate 303. They are used to limit the two sides of the box frame 8 to prevent the box frame 8 from shifting and to avoid affecting the stamping quality of the box frame 8. The sides of the two baffles 5 are provided with two oppositely arranged third slide grooves 6. The limiting plate 306 is provided with a third slide rail 7 that corresponds to and slides with the third slide groove 6. Through the limiting effect of the third slide groove 6 on the third slide rail 7, the third slide rail 7 can only move up and down along the third slide groove 6, which improves the stability of the buffer on the lower mold 3 and avoids affecting the stamping effect.

[0022] Working principle: like Figure 2 , 4As shown in Figures 7 and 9, when the metal stamping machine is in use, the upper mold 2 and the lower mold 3 are adjusted according to the side length of the box frame 8 of the same batch. By turning the first knob 210 by hand, the two upper mold cores 201 can slide closer or further away from each other along the length direction of the first slide rail 209, thereby adjusting the distance between the two upper mold cores 201. Similarly, by turning the second knob 309 by hand, the two lower mold cores 301 can slide closer or further away from each other along the length direction of the second slide rail 307, thereby adjusting the distance between the two lower mold cores 301. After the upper mold 2 and the lower mold 3 are adjusted, the box frame 8 to be processed is fitted into the lower mold 3, so that the inner edge of the box frame 8 to be processed is laid flat on the top of the two lower mold cores 301. Then, the upper mold 2 is pressed down by the punching head of the punching machine body 1, so that the corners of the box frame 8 can be chamfered and punched.
