Detailed Embodiment

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figures 1 - 4 , the present utility model provides two technical solutions:

[0024] The first implementation method: A rapid die plate positioning device, including a mounting plate 1. A groove plate 3 is fixedly installed on the right side of the top surface of the mounting plate 1. A positioning plate 4 is movably installed on the top surface of the groove plate 3, and the top surface on the right side of the positioning plate 4 is beveled. A support and positioning mechanism 2 is arranged on the top surface of the mounting plate 1 for positioning the die plate. The support and positioning mechanism 2 includes:

[0025] A moving component 21, arranged on the top surface of the mounting plate 1 for adjusting the position of the positioning plate 4;

[0026] A support component 22, arranged inside the positioning plate 4 for supporting the die plate. The support component 22 includes a notch 225 opened on the top surface of the positioning plate 4. A rotating shaft 222 is movably installed inside the positioning plate 4. A support plate 223 is movably installed on the outer side of the rotating shaft 222, and the bottom surface on the right side of the support plate 223 is beveled. A connecting plate 221 is fixedly installed on the left side of the rotating shaft 222. A limiting shaft 224 is fixedly installed inside the notch 225. A tension spring 226 is fixedly installed on the left side of the bottom surface of the connecting plate 221. An activity groove 229 is opened inside the positioning plate 4. A convex block 227 is movably installed inside the activity groove 229. A fixing pin 228 is fixedly installed on the left side of the convex block 227. An adjusting component is arranged on the outer side of the positioning plate 4 for adjusting the supporting force of the support plate 223. The adjusting component includes a limiting groove 2210 opened on the left side of the positioning plate 4. Mounting frames 2212 are fixedly installed on the front and rear sides of the positioning plate 4. An adjusting screw 2211 is movably installed inside the mounting frame 2212. The left and right sides of the notch 225 penetrate through the inside of the positioning plate 4 and extend to the outside of the positioning plate 4. The right side of the support plate 223 penetrates through the inside of the notch 225 and extends to the right side of the positioning plate 4. The bottom surface of the connecting plate 221 is closely attached to the outer side of the limiting shaft 224, and the position of the connecting plate 221 can be limited by the limiting shaft 224. The bottom end of the tension spring 226 is fixedly installed on the outer side of the fixing pin 228, and the connecting plate 221 can be pulled by the elastic force of the tension spring 226 to make the bottom surface of the connecting plate 221 closely attached to the outer side of the limiting shaft 224. The front and rear sides of the activity groove 229 penetrate through the inside of the positioning plate 4 and extend to the outside of the positioning plate 4. The left side of the convex block 227 movably penetrates through the inside of the limiting groove 2210 and is fixedly installed at the right end of the fixing pin 228. The front and rear sides of the convex block 227 penetrate through the inside of the activity groove 229 and extend to the inside of the mounting frame 2212. The top end of the adjusting screw 2211 movably penetrates through the inside of the mounting frame 2212 and extends to the top surface of the mounting frame 2212. The bottom end of the adjusting screw 2211 threadedly penetrates through the top surface of the convex block 227 and is movably installed on the bottom surface of the inner cavity of the mounting frame 2212. Rotating the adjusting screw 2211 can drive the convex block 227 to lower the fixing pin 228. Then, the fixing pin 228 will stretch the length of the tension spring 226 to adjust the elastic force of the tension spring 226. At this time, the supporting force of the support plate 223 can be increased through the connecting plate 221.

[0027] The positioning of the sheet material is facilitated by the provided support plate 223 and tension spring 226. During use, the sheet material is placed on the support plate 223. At this time, the tension of the tension spring 226 will pull the connecting plate 221, and the support plate 223 will support and position the sheet material, ensuring the flatness of the sheet material. This avoids the situation where for parts with a large curvature of the surface, the sheet material bends due to its own weight, resulting in inconsistent product dimensions.

[0028] The second implementation mode is mainly different from the first implementation mode in that: the moving component 21 includes a bolt 211 threadedly installed on the top surface of the mounting plate 1. An active screw rod 212 is movably installed inside the groove plate 3. A slider 213 is fixedly installed on the bottom surface of the positioning plate 4. The bottom surface of the slider 213 is slidably installed inside the groove plate 3, and the slider 213 can limit the movement track of the positioning plate 4 through the groove plate 3. The right end of the active screw rod 212 threadedly penetrates the left side of the slider 213 and is movably installed on the right side of the inner cavity of the groove plate 3. The left end of the active screw rod 212 movably penetrates the inside of the groove plate 3 and extends to the left side of the groove plate 3. Rotating the active screw rod 212 can drive the slider 213 to drive the positioning plate 4 to move horizontally for position adjustment. The bottom end of the bolt 211 threadedly penetrates the top surface of the mounting plate 1 and extends to the bottom surface of the mounting plate 1. Rotating the bolt 211 can fix the mounting plate 1 in a suitable position.

[0029] The position of the positioning plate 4 is conveniently adjusted by the provided active screw rod 212. During use, the sheet material is placed on the top surface of the support plate 223, and then the active screw rod 212 is rotated to drive the slider 213 to adjust the position of the positioning plate 4. When one side of the positioning plate 4 is attached to the outside of the sheet material, stop rotating the active screw rod 212 to fix the position of the positioning plate 4, and then stamping can be carried out, which is convenient to use and has good practicability.

[0030] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0031] In use, the operator installs the device on the machine tool through the connecting plate 221, and then places the sheet material on the top surface of the support plate 223. At this time, the pulling force of the tension spring 226 will pull the connecting plate 221, and the support plate 223 will support the sheet material for positioning, ensuring the flatness of the sheet material. Then, rotate the movable screw 212 to drive the slider 213 to adjust the position of the positioning plate 4. When one side of the positioning plate 4 is attached to the outer side of the sheet material, stop rotating the movable screw 212 to fix the position of the positioning plate 4 to position the sheet material. Then, start the machine tool to drive the upper die insert to press down the sheet material. At this time, the support plate 223 will rotate through the rotating shaft 222, and then the sheet material will fall onto the lower die of the mold to participate in the mold work. When the machine tool returns, the upper die insert will be separated from the support plate 223. Then, the elastic force of the tension spring 226 will pull the connecting plate 221 to drive the support plate 223 to reset for convenient use next time. When the sheet material is heavy, rotate the adjusting screw 2211 to drive the convex block 227 to lower the fixing pin 228. Then, the fixing pin 228 will lengthen the length of the tension spring 226 to adjust the elastic force of the tension spring 226. At this time, the supporting force of the support plate 223 can be increased through the connecting plate 221.
