Description

Technical Field

[0001] The utility model relates to the technical field of spinning presses, and specifically relates to an auxiliary loading and unloading device for a spinning press. Background Technique

[0002] A spinning press is a machine used for metal processing. It changes the shape of metal by rotating the workpiece and applying pressure, and is usually used to manufacture cylindrical, conical or complex-shaped parts. It shapes the metal through a rotating tool, improving the processing efficiency and material utilization rate. The existing spinning presses with automatic loading and unloading perform loading from the side, that is, the workpiece is fed in from the side of the spinning press, and then the workpiece is pushed into the fixture by a pusher device.

[0003] For example, for an auxiliary loading and unloading device of a spinning press with the application number 202221783061.6, during use, the workpieces on both sides of the rotating shaft squeeze the material blocking rods, making the material blocking rods fixed differently, so that the rotating shaft cannot rotate. When the workpiece at the material storage tank is pushed out by the ejector device, at this time, the material blocking rod in front of the upper feeding tray in front of the rotating shaft rolls forward, and the workpiece behind the rotating shaft pushes the material blocking rod to make the material blocking rod rotate. At this time, the workpiece directly below the detection ring enters in front of the rotating shaft, and the workpiece behind the rotating shaft enters below the rotating shaft.

[0004] It has the following disadvantages:

[0005] The loading of the workpiece depends on whether the ejector device works. This results in the auxiliary loading and unloading device only playing a role of placing the workpiece, making the function of the auxiliary loading and unloading device relatively single. In addition, the workpieces processed by the spinning press are commonly plate-shaped. If the plate-shaped workpiece is placed on the upper feeding tray, there will be a large contact area between the plate-shaped workpiece and the upper feeding tray. In this way, there is a large frictional force between the plate-shaped workpiece and the upper feeding tray. Therefore, after the workpiece in front on the upper feeding tray is pushed out, the workpiece behind the front workpiece cannot timely fill the vacant workpiece placement position. When the ejector device pushes out the workpiece again, there is a phenomenon that the workpiece is pushed out empty, and further, there will be a phenomenon of workpiece breakage on the upper feeding tray.

[0006] Therefore, we propose an auxiliary loading and unloading device for a spinning press to solve the above problems. Content of the Utility Model

A servo motor 15 is fixedly arranged on the fixing plate 10. The output end of the servo motor 15 is butted against the limiting block 11.

[0032] Through the settings of the first sliding rod 4, the collar 5, the second sliding rod 6, the slider 7, the connecting plate 8, the loading and unloading push block 9, the fixing plate 10, the limiting block 11, the limiting rod 12, the L-shaped plate 13, the compression spring 14, and the servo motor 15, not only can the workpiece placed on the loading plate 1 be continuously fed to the spinning machine, making the device have versatility, but also it can be avoided that after the previous workpiece is conveyed to the spinning machine, the workpiece behind the previous workpiece cannot timely fill the vacant workpiece placement position, thus causing the phenomenon of interrupted loading of the workpiece on the loading plate 1.

[0033] An inclined plate 16 is arranged on one side of the loading plate 1. One end of the inclined plate 16 is fixedly connected to the two loading plates 1. The setting of the inclined plate 16 can guide the loaded workpiece, thereby reducing the inertia of the workpiece falling towards the spinning machine, and further playing a role in protecting the spinning machine.

[0034] A baffle plate 17 is fixedly arranged on the upper end surface of the feeding plate 1, and the cross section of the baffle plate 17 is in a U shape. A discharge port 18 is formed at the lower end of one side wall surface of the baffle plate 17, and the positions of the two discharge ports 18 correspond to each other. Clamping plates 19 are arranged on the inner sides of the baffle plate 17, a threaded rod 20 is rotatably arranged on the clamping plates 19, one end of the threaded rod 20 passes through the baffle plate 17, a rotating block 21 is fixedly arranged at the end of the threaded rod 20 passing through the baffle plate 17, and the threaded rod 20 passing through the baffle plate 17 is in threaded connection with the baffle plate 17. Guide rods 22 are arranged on both sides of the threaded rod 20, one end of the guide rod 22 is fixedly connected with the clamping plate 19, the other end of the guide rod 22 passes through the baffle plate 17, and a positioning block 23 is fixedly arranged at the end of the guide rod 22 passing through the baffle plate 17.

[0035] Through the arrangement of the baffle plate 17, the position of the workpiece placed on the feeding plate 1 can be restricted. Through the arrangement of the clamping plates 19, the threaded rod 20, and the rotating block 21, the workpiece placed on the feeding plate 1 can be corrected, so that the workpiece placed on the feeding plate 1 is more orderly. Through the arrangement of the guide rods 22, the moving guiding effect on the clamping plates 19 is achieved, so that the movement of the clamping plates 19 is more stable.

[0036] The working principle of this utility model:

[0037] First, place the workpieces to be processed on the upper end face of the loading plate 1 in sequence. Then, rotate the rotating block 21. The rotation of the rotating block 21 drives the threaded rod 20 to rotate. The rotation of the threaded rod 20 drives the clamping plate 19 to move towards the workpiece on the upper end face of the loading plate 1. When the two clamping plates 19 contact the workpiece, continue to rotate the rotating block 21. At this time, the clamping plate 19 clamps the workpiece until the two sides of the workpiece are on the same horizontal plane. When it is necessary to add the workpiece to the spinning machine, start the servo motor 15. The start of the servo motor 15 drives the limiting block 11 to rotate. During the rotation of the limiting block 11, the compression of the spring 14 will push the L-shaped plate 13 to extend the length of the limiting rod 12 protruding. The rotation of the limiting block 11 drives the L-shaped plate 13 to move. The movement of the L-shaped plate 13 drives the slider 7 to move along the first sliding rod 4. The movement of the slider 7 drives the connecting plate 8 to move. The movement of the connecting plate 8 drives the loading and unloading push block 9 to move until the loading and unloading push block 9 is inserted into the upper end face between the two loading plates 1. Continue to rotate the limiting block 11, and the limiting rod 12 continues to protrude. The protrusion of the limiting rod 12 will drive the loading and unloading push block 9 to move. The movement of the loading and unloading push block 9 will push the workpiece at the lowermost end on the upper end face of the loading plate 1 from the discharge port 18 to the inclined plate 16. The workpiece falling on the inclined plate 16 will slide to the spinning machine for processing. When the slider 7 moves to the end of the stroke, the limiting rod 12 is in a horizontal state, and the loading and unloading push block 9 pushes the workpiece at the lowermost end on the upper end face of the loading plate 1 to the inclined plate 16. Continue to rotate the limiting block 11, and the L-shaped plate 13 connected to the limiting block 11 flips to the lower side of the limiting block 11. At this time, continue to rotate the limiting block 11. During the rotation of the limiting block 11, the compression spring 14 between the limiting block 11 and the L-shaped plate 13 drives the loading and unloading push block 9 to move downward through the slider 7, so that the loading and unloading push block 9 is located below the loading plate 1. The rotation of the limiting block 11 will drive the loading and unloading push block 9 to return to its original position along the first sliding rod 4. When the limiting block 11 rotates to a horizontal state, continue to rotate the limiting block 11. At this time, the loading and unloading push block 9 will continue to be inserted into the upper end face between the two loading plates 1. Repeat the above steps to continue loading the workpieces to the spinning machine.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
