[0004] However, in the prior art, the clamping plates in the positioning structure are usually set as horizontal plates, which can only fix the metal workpiece on one axis, resulting in less restraint on the metal workpiece. This may cause the metal workpiece to shift during stamping, deforming the finished product. Therefore, the utility model proposes a punching press positioning structure for stamping and processing metal structures to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a punching press positioning structure for stamping and processing metal structures, so as to solve the problem in the above background technique that the clamping plates set as horizontal plates in the positioning structure can only fix the metal workpiece on one axis, resulting in less restraint on the metal workpiece, and the metal workpiece may shift during stamping, deforming the finished product.

[0022] For the sake of simplicity and illustration, the principles of the embodiments are mainly described by referring to examples. In the following description, many specific details are set forth to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily making these embodiments difficult to understand. Additionally, all embodiments can be used in combination with each other.

[0023] Please refer to Figures 1 to 3 , the present utility model provides a technical solution:

[0024] Embodiment 1, a punch positioning structure for metal structure stamping processing, the punch positioning structure for metal structure stamping processing includes: the main body 1 of the punch workpiece mounting seat.

[0025] Specifically, a placement groove 11 is provided on one side of the main body 1 of the punch workpiece mounting seat. The placement groove 11 can facilitate the placement of metal workpieces. Two clamping plates 4 that move relatively are slidably connected to one end of the main body 1 of the punch workpiece mounting seat. The clamping plates 4 are arranged in a "V" shape and correspond to the position of the placement groove 11. After the workpiece is placed, controlling the relative sliding of the clamping plates 4 can clamp the workpiece. Two symmetrically arranged fixing blocks 5 are fixedly connected to the side surface of the clamping plate 4. A second screw rod 6 is rotatably installed at one end of the fixing block 5. A baffle 7 is threadedly sleeved on the side surface of the second screw rod 6. The baffle 7 is inclined and slidably connected to the fixing block 5. After the clamping plate 4 is in place, rotating the second screw rod 6 can control the sliding of the baffle 7 to contact the workpiece, further restricting and fixing the metal workpiece from the Z-axis. A fixing component for restricting the rotation of the second screw rod 6 is provided at one end of the fixing block 5. The fixing component can effectively restrict the rotation of the second screw rod 6, making the baffle 7 more stable.

[0026] In order to better control the relative sliding movement of the clamping plates 4, a first screw rod 2 driven by a motor 3 to rotate is rotatably inserted at one end of the main body 1 of the punch workpiece mounting seat of the present application. Two symmetrically arranged threaded grooves are provided on the side surface of the first screw rod 2, and a limit block 21 is fixedly connected to one end of the first screw rod 2. The limit block 21 can prevent the first screw rod 2 from sliding. Both clamping plates 4 are threadedly sleeved on the first screw rod 2. When the motor 3 drives the first screw rod 2 to rotate, it will directly drive the two clamping plates 4 to move relatively, making the fixation of the metal workpiece more convenient and fast.

[0027] In order to facilitate the sliding of the clamping plate 4, a first slider 42 arranged in a "T" shape is fixedly connected to one side of the clamping plate 4 of the present application. A first sliding groove 12 for the first slider 42 to slide is provided on one side of the main body 1 of the punch workpiece mounting seat. The first slider 42 is threadedly sleeved on the first screw rod 2. In this way, it can ensure that the clamping plate 4 slides on the main body 1 of the punch workpiece mounting seat, and at the same time, it can limit the displacement and rotation of the clamping plate 4 in other directions.

[0028] To facilitate the installation of the first lead screw 2 and further improve the clamping effect of the clamping plate 4, a first rubber pad 41 is fixedly connected to the side of the clamping plate 4 in contact with the metal workpiece in this application. The first rubber pad 41 can increase the friction between the clamping plate 4 and the metal workpiece, thereby better restricting the workpiece, and the first rubber pad 41 can also protect the metal workpiece. An installation groove 13 for the rotational installation of the first lead screw 2 is provided at one end of the main body 1 of the punch workpiece mounting seat, and the installation groove 13 can facilitate the rotational installation of the first lead screw 2.

[0029] To facilitate the sliding of the baffle 7, a second slider 71 shaped like a "T" is fixedly connected to one end of the baffle 7 in this application. A second sliding groove 51 for the sliding of the second slider 71 is provided on one side of the fixed block 5. The second slider 71 is threadedly sleeved on the second lead screw 6, so that it can be ensured that when the second lead screw 6 rotates, it can drive the baffle 7 to slide, and at the same time, the rotation of the baffle 7 can be restricted.

[0030] For the further stability of the baffle 7, the fixing component in this application includes a limiting plate 8 shaped like a "V". A second rubber pad 83 is fixedly connected to the side of the limiting plate 8 in contact with the second lead screw 6. A polygonal guide rod 82 is fixedly connected to one end of the limiting plate 8. An installation plate 9 is fixedly connected to one side of the fixed block 5. The polygonal guide rod 82 is slidably inserted into the installation plate 9, and a spring 81 is fixedly connected between the installation plate 9 and the limiting plate 8. After the baffle 7 is in place, the limiting plate 8 and the second rubber pad 83 slide under the action of the spring 81 and then contact the second lead screw 6, so as to restrict the rotation of the second lead screw 6 by using friction, thereby ensuring that the baffle 7 will not slide. The installation plate 9 can provide a better installation space for the limiting plate 8, and the polygonal guide rod 82 can ensure the sliding of the limiting plate 8 while preventing the limiting plate 8 from rotating.

[0031] During actual implementation, first insert the workpiece into the placement groove 11, and then control the first lead screw 2 to rotate by the motor 3. The rotating first lead screw 2 will drive the two clamping plates 4 to slide and then clamp and fix the workpiece. Then rotate the second lead screw 6 to control the sliding of the baffle 7 to further restrict the workpiece. This can fix the workpiece from multiple constraint ends. After the baffle 7 is fixed, the limiting plate 8 and the spring 81 slide under the action of the spring 81 and then contact the second lead screw 6, so as to restrict the rotation of the second lead screw 6 and ensure the stability of the baffle 7.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
