Description

Technical Field

[0001] The utility model belongs to the technical field of stamping devices, and particularly relates to a stamping device for automobile parts. Background Technique

[0002] Stamping is a forming processing method that applies external forces to plates, strips, tubes, profiles, etc. by a press and a die, causing them to undergo plastic deformation or separation, so as to obtain workpieces (stamped parts) with the required shapes and dimensions. In the production process of automobile parts, stamping devices are usually used to stamp and process metal sheet parts.

[0003] Chinese utility model patent with publication number CN208912887U, a stamping device for automobile parts, includes a stamping table. A plurality of support frames are symmetrically and fixedly installed on the stamping table. The upper ends of the plurality of support frames are jointly and fixedly installed with a support table. The support table is provided with an upper die through a stamping structure. An installation groove is formed on the upper surface of the stamping table. A lower die is in interference fit in the installation groove. Parts are placed on the lower die. A plurality of fixed columns are fixedly installed on the stamping table. A pressing plate is rotatably connected to each fixed column, and the lower surface of the pressing plate is attached to the upper surface of the parts. The advantages are as follows: The utility model fixes the parts, so that the parts will not shift during the stamping process, improving the stamping accuracy.

[0004] However, the above-mentioned utility model patent has the following technical problems in actual use:

[0005] First, the above device places the workpiece on the lower die, and horizontally rotates the pressing plates at the tops of a plurality of fixed columns outside the lower die so that the lower surfaces of the pressing plates contact the upper surface of the workpiece, thereby pressing and fixing the workpiece by using the pressing plates to ensure the accuracy during the stamping process. However, this method requires manual rotation of a plurality of pressing plates each time when fixing the workpiece to be stamped and taking out the stamped workpiece, so that the pressing plates are separated from the workpiece to facilitate the placement and taking operations, thus greatly increasing the labor amount required by the manual work and reducing the stamping efficiency of the above device for the workpiece.

[0006] Second, in addition, when rotating the pressing plates to operate the loading and unloading of the workpiece, the device is in a standby state. After each workpiece is processed, the device needs to be in a standby state once, and continuous stamping processing of the workpiece cannot be realized. The continuous multiple standby waits will greatly increase the time consumed by the above device during the stamping process and increase the working time required by the manual work. Content of the Utility Model

[0007] The present utility model provides a stamping device for automobile parts and components, aiming to solve the problems mentioned in the above background technology. When the above device picks up and places workpieces, it is necessary to manually rotate the pressure plate, which greatly increases the labor intensity of workers, reduces the stamping efficiency of the above device. At the same time, after each workpiece is processed, the above device needs to wait for standby. Multiple consecutive standby waits will greatly increase the time wasted by the above device during stamping.

[0008] The present utility model is implemented as follows. A stamping device for automobile parts and components includes: a workbench, on which a fixed plate is erected and installed. The fixed plate is movably connected with an upper die stamping component, and the workbench is rotatably connected with a rotating disk. A plurality of lower die seats are fixedly installed on the rotating disk at equal angles. A stamping cavity for accommodating workpieces is provided on the top wall of each lower die seat. Among them, when one of the lower die seats rotates horizontally with the rotating disk to the lower part of the upper die stamping component, the upper die stamping component moves vertically downward and stamps the workpiece in the stamping cavity into shape. A rotation driving component is arranged on the bottom wall of the workbench and is movably connected with the rotating disk. The rotation driving component is used to control the multi-angle rotation of the rotating disk. In this solution, in the present device, when one of the lower die seats rotates horizontally to the lower part of the upper die seat, the output end of the electric push rod extends and pushes the upper die seat downward. At the same time, the stamping seat at the bottom of the upper die seat is used to stamp the workpiece in the stamping cavity. When the stamping seat moves downward, the pressing component at its bottom will first contact the workpiece in the stamping cavity, and at the same time, the pressing component presses the workpiece to prevent the workpiece from running off. The present device presses the workpiece by moving the stamping seat downward, without the need for manual repeated operation to fix the workpiece, greatly reducing the workload of workers and improving the stamping efficiency of the present device for workpieces.

[0009] In addition, by arranging a plurality of lower die seats on the rotating disk, the rotating disk can rotate the plurality of lower die seats carrying workpieces to the lower part of the upper die stamping component in turn, so that there is no need for the equipment to wait for the time of loading and unloading materials, and continuous stamping processing can be realized.
