[0001] The utility model relates to the technical field of punching presses, in particular to a blanking mechanism and a punching press for metal structure processing. Background Technique

[0002] A punching press is a mechanical device used for processing metal plates, mainly for processes such as stamping, shearing, bending, and forming.

[0003] At present, in order to facilitate the removal of the processed parts from the mold, a blanking mechanism composed of structures such as vacuum suction cups is usually used to adsorb the parts and then move them to the designated position.

[0004] However, during the long-term use of the suction cup, it may be damaged due to residual metal debris on the workpiece, resulting in a decrease in the suction force of the suction cup. During the transportation of metal workpieces, the metal workpieces may fall and deform. Therefore, the utility model proposes a blanking mechanism and a punching press for metal structure processing to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a blanking mechanism and a punching press for metal structure processing, so as to solve the problem that during the long-term use of the vacuum suction cup, the suction cup may be damaged due to residual metal debris on the workpiece, resulting in a decrease in the suction force and causing the metal workpiece to fall and deform during transportation as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a blanking mechanism, the blanking mechanism includes:

[0007] A linear module main body, the linear module main body is fixedly connected to the punching press main body, and a mounting block is slidably connected to one side of the linear module main body. One end of the mounting block is fixedly connected to a hydraulic cylinder, one end of the hydraulic cylinder is fixedly connected to a vacuum suction cup main body. Two mounting plates symmetrically arranged with the position of the vacuum suction cup main body as the center are arranged on one side of the mounting block. A "V"-shaped clamping plate is slidably connected to one side of the mounting plate. A plurality of springs are fixedly connected between the clamping plate and the mounting plate. The upper end of the clamping plate is set as an inclined arc surface and the opening end faces the mounting plate. Two dial rods corresponding to the arc surface of the clamping plate are fixedly connected to the side surface of the push rod of the hydraulic cylinder.

[0008] Preferably, a lead screw driven by a motor to rotate is rotatably installed at one end of the mounting block. The lead screw is provided with two threaded grooves with opposite directions centered on the vacuum suction cup main body. Both mounting plates are threadedly sleeved on the lead screw and are slidably connected to the mounting block.

[0009] Preferably, one end of the mounting plate is fixedly connected to a slider shaped like a "T", and the slider is slidably connected to the mounting block and threadedly sleeved on the lead screw.

[0010] Preferably, a threaded hole for the threaded insertion of the lead screw is provided at one end of the slider, and a plurality of chutes for the sliding installation of the slider are provided on the side surface of the mounting block.

[0011] Preferably, an installation groove for the rotational installation of the mounting block is provided on one side of the mounting block, the installation groove communicates with the chute, and a limiting block is fixedly connected to one end of the lead screw.

[0012] Preferably, the mounting plate is shaped like an "L", and a plurality of telescopic rods are fixedly connected between the clamping plate and the mounting plate.

[0013] A punching machine for metal structure processing includes the above-mentioned blanking mechanism.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] In this device, two mounting plates symmetrically distributed with the vacuum suction cup main body as the center are arranged on the mounting block. The side surface of the mounting plate is slidably connected to a clamping plate shaped like a "V", and a plurality of springs are fixedly connected between the clamping plate and the mounting plate. When the hydraulic cylinder drives the vacuum suction cup main body to slide down to adsorb the workpiece, the two clamping plates will be pushed apart to both sides of the vacuum suction cup main body through the dial rod. When the vacuum suction cup main body drives the workpiece to slide up after adsorbing the workpiece, as the dial rod and the clamping plate are separated, the clamping plate will slide towards the workpiece under the action of the spring. After contacting the workpiece, the clamping plate will generate friction with the workpiece. At this time, if the adsorption force provided by the vacuum suction cup main body is seriously insufficient, the workpiece will be directly separated, rather than falling during the transportation process. The risk can be avoided in advance, and the damage of the suction cup of the vacuum suction cup main body can be detected earlier. If the adsorption force provided by the vacuum suction cup main body is sufficient to slide the workpiece to the required position, the clamping plate will clamp the workpiece under the action of the spring, reducing the load on the vacuum suction cup main body, thereby further improving the service life of the vacuum suction cup main body. This solves the problem that during the long-term use of the vacuum suction cup, the suction force may decrease due to damage to the suction cup caused by metal debris remaining on the workpiece, resulting in the metal workpiece falling and deforming during transportation.

[0024] For the purpose 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 obscuring these embodiments. Additionally, all embodiments can be used in combination with each other.

[0025] Please refer to Figures 1 to 4 , the present utility model provides a technical solution:

[0026] Embodiment 1, a blanking mechanism, the blanking mechanism includes: a linear module main body 1, a mounting block 2, a hydraulic cylinder 3, and a vacuum chuck main body 4.

[0027] Specifically, the linear module main body 1 is fixedly connected to the punch main body, and a mounting block 2 is slidably connected to one side of the linear module main body 1. By controlling the sliding of the mounting block 2 by the linear module main body 1, the workpiece can be transported away. One end of the mounting block 2 is fixedly connected to a hydraulic cylinder 3, and one end of the hydraulic cylinder 3 is fixedly connected to a vacuum chuck main body 4. The hydraulic cylinder 3 can control the vacuum chuck main body 4 to slide close to the workpiece. The vacuum chuck main body 4 can adsorb the workpiece by using the suction cup, so as to achieve good blanking. On one side of the mounting block 2, there are two mounting plates 5 symmetrically arranged with the position of the vacuum chuck main body 4 as the center. One side of the mounting plate 5 is slidably connected to a clamping plate 6 arranged in a "V" shape. A plurality of springs 7 are fixedly connected between the clamping plate 6 and the mounting plate 5. The clamping plate 6 can clamp and fix the workpiece adsorbed by the vacuum chuck main body 4 under the action of the springs 7, reducing the load of the vacuum chuck main body 4. At the same time, it can also detect the adsorption force of the vacuum chuck main body 4 through the friction force between the workpiece and the clamping plate 6 during the upward sliding process of the workpiece. The clamping plate 6 being arranged in a "V" shape facilitates the workpiece to slide into between the two clamping plates 6. The upper end of the clamping plate 6 is arranged as an inclined arc surface with the opening end facing the mounting plate 5. On the side of the push rod of the hydraulic cylinder 3, there are two toggle rods 8 corresponding to the arc surface position of the clamping plate 6. The toggle rods 8 can prevent the clamping plate 6 from clamping the vacuum chuck main body 4 under the action of the springs 7, and can also push the clamping plate 6 to both sides when the hydraulic cylinder 3 pushes the vacuum chuck main body 4 to slide down, enabling the vacuum chuck main body 4 to slide down better and enabling the workpiece to better contact the clamping plate 6.

[0028] To make the adaptability of this device wider, one end of the mounting block 2 of the present application is rotatably installed with a lead screw 9 driven by a motor 91. The lead screw 9 is provided with two threaded grooves with opposite directions centered on the vacuum chuck main body 4. Both mounting plates 5 are threadedly sleeved on the lead screw 9 and are slidably connected to the mounting block 2. By controlling the forward and reverse rotation of the lead screw 9 through the motor 91, the two mounting plates 5 can be driven to perform relative sliding movements, so that the clamping plate 6 can better adapt to the size of the workpiece.

[0029] In order to facilitate the installation of the mounting plate 5, one end of the mounting plate 5 of the present application is fixedly connected with a slider 51 arranged in a "T" shape, so that the mounting plate 5 can be prevented from being separated from the mounting block 2. The slider 51 is slidably connected to the mounting block 2 and is threadedly connected to the screw rod 9, so that the slider 51 can be driven to slide when the screw rod 9 rotates.

[0030] In order to facilitate the installation of the slider 51, a threaded hole 52 for threaded insertion of the screw rod 9 is provided at one end of the slider 51 of the present application, and a plurality of slide grooves 22 for sliding installation of the slider 51 are provided on the side of the mounting block 2. Through the cooperation between the slider 51 and the slide groove 22, the mounting block 2 can better support the mounting plate 5, and the threaded hole 52 can allow the slider 51 to better cooperate with the screw rod 9.

[0031] In order to facilitate the installation of the screw rod 9, a mounting groove 21 for rotatable installation of the mounting block 2 is opened on one side of the mounting block 2 of the present application, and the mounting groove 21 is connected to the slide groove 22, so that the slider 51 can be better installed on the screw rod 9. One end of the screw rod 9 is fixedly connected to a limiting block 92, and the limiting block 92 can prevent the screw rod 9 from sliding.

[0032] In order to ensure the stability of the splint 6, the mounting plate 5 of the present application is set to an "L" shape, which can provide more installation space for the splint 6. A plurality of telescopic rods 61 are fixedly connected between the splint 6 and the mounting plate 5. The telescopic rods 61 can allow the splint 6 to be slidably installed on the mounting plate 5 more stably.

[0033] The present application also discloses a punch press for metal structure processing, comprising any one of the above-mentioned blanking mechanisms.

[0034] During actual implementation, first, according to the size of the workpiece, the screw rod 9 is rotated to make the two mounting plates 5 slide to a suitable position so that the workpiece can be better inserted between the two clamping plates 6. Then, the hydraulic cylinder 3 controls the vacuum suction cup body 4 to slide and adsorb the workpiece. Then, the hydraulic cylinder 3 drives the vacuum suction cup body 4 to slide upward. As the vacuum suction cup body 4 continues to slide, the workpiece will contact the clamping plate 6, and then slide on the surface of the clamping plate 6 to insert it between the two clamping plates 6. In this process, if the suction cup of the vacuum suction cup body 4 is damaged and the adsorption force of the vacuum suction cup body 4 is insufficient, the friction force will cause the workpiece to directly detach from the vacuum suction cup body 4, thereby avoiding the risk of the workpiece being broken after it is lifted in advance. If the adsorption force of the vacuum suction cup body 4 is sufficient, the workpiece will be inserted between the two clamping plates 6 after sliding. Under the action of the spring 7, the two clamping plates 6 will clamp the workpiece, reducing the load on the suction cup of the vacuum suction cup body 4, thereby increasing the service life of the vacuum suction cup body 4.

[0035] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
