[0002] A press is a machine tool that processes materials by pressure. It processes parts by applying strong pressure to the blank to deform and break it. An open fixed-table press has high precision, reliable performance, and easy operation. It can be equipped with an automatic feeding device to achieve semi-automatic stamping operations. An open fixed-table press is suitable for various cold stamping processes such as shearing, blanking, punching, bending, and shallow drawing of sheet materials. It is widely used in various industrial manufacturing departments. At present, most of the presses in industrial and mining workshops are gantry structures. The hydraulic cylinder of the forging workpiece is installed on the gantry at the top, and the placement table of the forging workpiece is directly below the hydraulic cylinder, that is, below the gantry. When lifting heavy forging workpieces to or from the placement table, the hydraulic cylinder and gantry of the press block the lifting route of the workpiece, making it impossible to directly lift the workpiece into place. It needs to rely on manpower or other auxiliary methods. There are great hidden dangers during the placement process, and the safety of people and equipment cannot be guaranteed. Therefore, a press auxiliary feeding mechanism is particularly needed.

[0003] However, most of the existing auxiliary feeding mechanisms of presses need to stop and wait during stamping processing. After stamping is completed, the press needs to wait for feeding again, which causes a waste of processing interval time and further reduces the work efficiency of the stamping process. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 The utility model provides a technical solution, a press auxiliary feeding mechanism, including a press body 1 and a feeding mechanism 3, a support frame 2 is penetrated inside the press body 1, a surface side of the support frame 2 is provided with the feeding mechanism 3, and a surface side of the feeding mechanism 3 is provided with a clamping mechanism 4;

[0020] The feeding mechanism 3 includes a first motor 301, a first screw rod 302, a feed plate 303, a through hole 304 and a limit rod 305. The first motor 301 is installed on one side of the surface of the support frame 2, and the first screw rod 302 is connected to one side of the surface of the first motor 301. The first screw rod 302 is threadedly connected to the feed plate 303. A through hole 304 is provided on one side of the surface of the feed plate 303, and the interior of the through hole 304 passes through the limit rod 305. Through the arrangement of the first motor 301, the first screw rod 302, the feed plate 303, the through hole 304 and the limit rod 305, when in use, the first motor 301 is started first, and at this time, the first motor 301 drives the first screw rod 302 to rotate. The material plate 303 cannot rotate due to the restriction of the limiting rod 305, so that the first screw rod 302 drives the two groups of feed plates 303 to move in the direction of the first screw rod 302. When the feed plate 303 close to the press body 1 moves to the processing position, the first motor 301 stops. At this time, the press is started for processing, and at the same time, the other group of feed plates 303 can be fed. After the processing is completed, the first motor 301 is started again. At this time, the first motor 301 drives the feed plate 303 to move again, so that the feed plate 303 drives the processed material to leave the press body 1, and at the same time, the other group of feed plates 303 drives the material to the processing position, so that feeding can be carried out while processing, thereby improving work efficiency.

[0021] Furthermore, the first screw rod 302 is connected to the bearing of the support frame 2, and two groups of feed plates 303 are provided. Through the setting of the feed plates 303, when in use, the two groups of feed plates 303 can be alternately loaded and processed, thereby reducing the waiting time during the loading and processing process.

[0022] Furthermore, two groups of limit rods 305 are provided, and both ends of the limit rods 305 are fixedly connected to the support frame 2. Through the setting of the limit rods 305, when in use, the two groups of limit rods 305 can provide support for the feed plate 303. At the same time, the limit rods 305 can limit the position of the feed plate 303, so that the feed plate 303 cannot rotate with the first screw rod 302.

[0023] Furthermore, the clamping mechanism 4 includes a support plate 401, a second motor 402, a second screw rod 403, a slider 404, a clamping plate 405 and a fixing hole 406. One side of the surface of the feed plate 303 is connected to the support plate 401, one side of the surface of the support plate 401 is installed with the second motor 402, one side of the surface of the second motor 402 is connected with the second screw rod 403, one side of the surface of the second screw rod 403 is threadedly connected with the slider 404, one side of the surface of the slider 404 is fixedly connected with the clamping plate 405, one side of the surface of the clamping plate 405 is provided with a fixing hole 406. The arrangement of the clamping plates 405 and the fixing holes 406 is such that, when in use, the material is first placed on the surface of the support plate 401, and then the second motor 402 is started. At this time, the second motor 402 drives the second screw rod 403 to rotate. Since the two groups of sliders 404 are restricted by the support plate 401 and cannot rotate, the second screw rod 403 drives the two groups of sliders 404 to move relative to each other along the direction of the second screw rod 403, and the two groups of sliders 404 drive the two groups of clamping plates 405 to move relative to each other, so that the two groups of clamping plates 405 clamp the material. At the same time, the material that needs to be further fixed can be fixed through the fixing holes 406, thereby ensuring that the material does not move during transportation and processing.

[0024] Furthermore, the threads at both ends of the second screw rod 403 are in opposite directions, and the second screw rod 403 is connected to the support plate 401 bearing. Through the setting of the second screw rod 403, when in use, the second screw rod 403 can drive the two sets of sliders 404 to move relatively close or relatively away through the threads at both ends with opposite directions, thereby achieving the purpose of clamping and releasing materials.

[0025] Furthermore, two groups of clamps 405 are provided, and seven groups of fixing holes 406 are provided. Through the provision of the clamps 405, when in use, the two groups of clamps 405 can clamp the material by pressing against the surface of the material, thereby achieving a limiting and fixing effect and preventing the material from sliding.

[0026] Working principle: firstly, place the material on the surface of the support plate 401, then start the second motor 402, at this time the second motor 402 drives the second screw rod 403 to rotate, because the two sets of sliders 404 are restricted by the support plate 401 and cannot rotate, the second screw rod 403 drives the two sets of sliders 404 to move relative to each other along the direction of the second screw rod 403, the two sets of sliders 404 drive the two sets of clamping plates 405 to move relative to each other, so that the two sets of clamping plates 405 clamp the material, and at the same time, the material that needs to be further fixed can be fixed through the fixing hole 406, so as to ensure that the material does not move during transportation and processing, and then start the first motor 301, at this time the first motor 301 drives the first screw rod 302 to rotate, because the two sets of feed plates 303 are restricted by the limiting rod 305 Unable to rotate, the first screw rod 302 drives the two groups of feed plates 303 to move along the direction of the first screw rod 302. When the feed plate 303 close to the press body 1 moves to the processing position, the first motor 301 stops. At this time, the press is started for processing, and at the same time, the other group of feed plates 303 can be fed. After the processing is completed, the first motor 301 is started again. At this time, the first motor 301 drives the feed plate 303 to move again, so that the feed plate 303 drives the processed material to leave the press body 1, and at the same time, the other group of feed plates 303 drives the material to the processing position, so that feeding can be carried out while processing. The two groups of feed plates 303 can be fed alternately, thereby reducing the waiting time during the feeding process and improving work efficiency.
