[0010] Preferably, the inner surface of the adjusting groove is symmetrically slidably connected with adjusting blocks, and the inner surfaces of the two adjusting blocks are threadedly connected with a bidirectional threaded rod.

A clamping plate is fixedly connected to one side of each of the two connecting blocks located on the same side. The two clamping plates are respectively fixedly connected to the opposite sides of the left and right ends of the four connecting blocks, and pressure sensors are fixedly connected to the opposite sides of the inner surfaces of the two clamping plates.

[0013] Preferably, each of the two clamping plates is symmetrically fixedly connected to a fixing seat at the top, and the inner surfaces of the two fixing seats on the same side are rotatably connected to a bidirectional threaded rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the implementation of this utility model, by setting up a fixing mechanism, some existing punch press die fixing devices require manual adjustment and fixing in actual use, resulting in a low degree of automation. Therefore, the adjusting mechanism can drive the two fixing mechanisms to move in relative or opposite directions, thereby fixing the die at the clamping plate.

When the two clamping plates move in opposite directions, the springs on both sides are compressed. When the two clamping plates move in opposite directions to clamp and fix the mold, under the elastic action of the springs themselves, they can provide a squeezing force from the two end positions to the clamping plates in opposite directions, thereby avoiding connection fatigue between the two bidirectional threaded rods and the clamping plates and the phenomenon of loosening at the clamping plates.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Example 1

[0028] like Figure 1 As shown, a punch die fixing device includes an installation mechanism 1. An adjustment mechanism 2 is fixedly connected to the middle of the left end of the installation mechanism 1. Support base columns 3 are fixedly connected to the four corners of the bottom of the installation mechanism 1. Fixing mechanisms 4 are symmetrically installed on the outer surface of the adjustment mechanism 2. Both fixing mechanisms 4 are slidably connected to the installation mechanism 1. Auxiliary mechanisms 5 are symmetrically installed on opposite sides of the two fixing mechanisms 4.

[0029] In this embodiment, the mold is placed on opposite sides of two clamping plates 403. The controller 206 and the drive motor 205 are controlled by the control switch 208, so that the drive motor 205 drives the bidirectional threaded rod 202 to rotate and connect with the adjusting block 201. This achieves the purpose of the two U-shaped brackets 401 moving left and right with the upper fixing mechanism 4 and the auxiliary mechanism 5. The pressure sensor 404 is electrically connected to the controller 206. When the two clamping plates 403 move to fit against the left and right sides of the outer surface of the mold, which is enough to fix the mold, the pressure sensor 404 is electrically connected to the controller 206, so that the drive motor 205 stops driving the bidirectional threaded rod 202, thereby achieving the purpose of limiting and fixing the left and right sides of the mold.

[0030] Then, rotate the handle 410 to move the two clamping plates 408 on the same side in opposite directions, clamping and fixing the left and right sides of the mold from the front and rear sides respectively. When the four clamping plates 408 move, the four limiting plates 501 move with the four clamping plates 408 respectively.

[0031] When the two clamping plates 408 move in opposite directions, the springs 502 on both sides are compressed. When the two clamping plates 408 move in opposite directions to clamp and fix the mold, the elasticity of the springs 502 can help to squeeze the clamping plates 408 in opposite directions from both ends, thereby avoiding fatigue in the connection between the bidirectional threaded rod 406 and the clamping plate 408 and the phenomenon of loosening at the clamping plate 408. The overall operation is simple and convenient.

[0032] For details, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 In this embodiment, the installation mechanism 1 includes a processing table 101. An adjustment groove 102 is provided on the lower side of the middle of the processing table 101. Adjustment blocks 201 are symmetrically slidably connected to the inner surface of the adjustment groove 102. The inner surfaces of the two adjustment blocks 201 are threadedly connected to a bidirectional threaded rod 202. The outer surfaces of the left and right ends of the bidirectional threaded rod 202 are rotatably connected to bearings 203.

[0033] Further reference Figure 5 and Figure 6 In this embodiment, a drive box 204 is fixedly connected to the middle of the left end of the processing table 101. The left end of the bidirectional threaded rod 202 passes through the left side of the inner surface of the processing table 101 and the right side of the inner surface of the drive box 204. A drive motor 205 and a controller 206 are fixedly connected to the inner surface of the drive box 204. The left end of the bidirectional threaded rod 202 is rotatably connected to the output end of the drive motor 205. A maintenance door panel 207 is engaged with the left side of the inner surface of the drive box 204. A control switch 208 is fixedly connected to the middle of the inner surface of the maintenance door panel 207.

[0034] Further reference Figure 2 , Figure 3 and Figure 5 In this embodiment, a U-shaped bracket 401 is fixedly connected to the bottom of each of the two adjusting blocks 201, and a connecting block 402 is fixedly connected to the top of each of the two U-shaped brackets 401 symmetrically. A clamping plate 403 is fixedly connected to one side of the two connecting blocks 402 located on the same side. The two clamping plates 403 are fixedly connected to the opposite sides of the left and right ends of the four connecting blocks 402 respectively. A pressure sensor 404 is fixedly connected to the opposite sides of the inner surface of the two clamping plates 403.

[0035] Further reference Figure 2 and Figure 3In this embodiment, the tops of the two clamping plates 403 are symmetrically fixedly connected to the fixing seats 405. The inner surfaces of the two fixing seats 405 on the same side are rotatably connected to the bidirectional threaded rods 406. The front and rear sides of the outer surfaces of the two bidirectional threaded rods 406 are symmetrically threaded to the clamping plates 408. The rear ends of the two bidirectional threaded rods 406 penetrate the inner surfaces of the two rear fixing seats 405. The rear ends of the two bidirectional threaded rods 406 are fixedly connected to the handles 410. The tops of the two fixing seats 405 on the same side are fixedly connected to the U-shaped limiting rods 407. The opposite surfaces of the two clamping plates 408 on the same side are fixedly connected to the protective pads 409.

[0036] The adjusting mechanism 2 can drive the two fixing mechanisms 4 to move in opposite directions, thereby fixing the mold at the clamping plate 403. By turning the handle 410, the distance between the two clamping plates 408 can be adjusted, thereby achieving the effect of clamping and fixing the mold in the longitudinal direction. This helps to enhance the applicability of the fixing mechanism 4, avoid the trouble of repeatedly disassembling the mold fixing device, and thus improve the overall work efficiency.

[0037] Example 2

[0038] This embodiment adds an auxiliary mechanism 5 to assist in clamping the fixing mechanism 4 based on the first embodiment. By setting the auxiliary mechanism 5, fatigue in the connection between the bidirectional threaded rod 406 and the clamping plate 408 is avoided, and the clamping plate 408 does not become loose.

[0039] For details, please refer to Figure 2 , Figure 3 and Figure 4 In this embodiment, the opposite sides of the two clamping plates 408 located at the same end are fixedly connected to the limiting plates 501, the opposite sides of the two limiting plates 501 located on the same side are fixedly connected to the limiting telescopic rods 503, the outer sides of the four limiting telescopic rods 503 are slidably connected to the springs 502, the opposite sides of the outer surfaces of the two limiting telescopic rods 503 located on the same side are fixedly connected to the sleeve plates 504, and the opposite sides of the two sleeve plates 504 located at the same end are respectively fixedly connected to the end sides of the opposite sides of the two clamping plates 403.

[0040] An auxiliary mechanism 5 is provided on one side of the clamping plate 408. When the two clamping plates 408 move in opposite directions, the springs 502 on both sides are compressed. When the two clamping plates 408 move in opposite directions to clamp and fix the mold, the springs 502 can exert a squeezing force on the clamping plates 408 from both ends, thereby avoiding fatigue in the connection between the bidirectional threaded rod 406 and the clamping plate 408 and the phenomenon of loosening at the clamping plate 408.

[0041] The controller 206 in this solution can be a controller that can be matched with the drive motor 205 in the prior art, and can play the role of controlling the rotation speed of the drive motor 205. The control switch 208 is electrically connected to the controller 206, and can play the role of controlling the controller 206 and the drive motor 205 through the control switch 208.

[0042] The pressure sensor 404 in this solution can be a TE Connectivity pressure sensor, which is remotely connected to the controller 206 to measure and monitor the pressure on the mold clamping and fixing.

[0043] Since the above devices are all very mature products in the prior art, they will not be described in detail in this application.

[0044] It should be noted that the specific installation method of the drive motor, the circuit connection method, and the control method used in this utility model are all conventional designs, and will not be described in detail here.
