Description

Technical Field

[0001] The utility model belongs to the field of stamping devices, and particularly relates to a metal stamping and forming device with spring-back blanking. Background Art

[0002] A metal stamping and forming device, as the name implies, uses the force of a stamping oil cylinder and the action of a mold to plastically deform a metal sheet to obtain parts with the required shape and size. This device is widely used in industrial production, especially in fields such as automobile manufacturing, home appliance production, and hardware tool processing.

[0003] In traditional stamping processes, after stamping, it is usually necessary for workers to use tools (such as pliers, suction cups, etc.) to remove the stamped parts from the mold one by one. This method is not only time-consuming and laborious, but also as the production volume increases, the efficiency problem becomes more prominent. Moreover, the operator frequently comes into contact with stamping equipment and molds, posing a risk of being accidentally injured or scalded by the machine, increasing the problem of potential safety hazards in the production process.

[0004] Therefore, a metal stamping and forming device with spring-back blanking is proposed. By setting a spring-back blanking structure, automatic efficiency after stamping can be achieved, thereby improving the working efficiency of blanking and avoiding potential safety hazards during work. Summary of the Utility Model

[0007] Preferably, by placing an object on the first elastic component, then driving the upper stamping plate to perform stamping work by starting the stamping oil cylinder. When the upper stamping plate contacts the second elastic component, the first elastic component and the second elastic component descend to perform stamping work. Then, start the stamping oil cylinder to drive the upper stamping plate to move upward, so that the first elastic component rebounds. The second elastic component remains stationary through the connecting pipe. Then, open the connecting pipe to allow the second elastic component to perform a rapid rebound operation, so that the object stamped on the second elastic component is shaken out through vibration, thereby realizing the work of rebound blanking.

[0008] Preferably, the first elastic component includes a first groove body, a first vulcanized rubber block, a protection plate, a first limiting column and a second groove body; the upper end of the support seat is fixedly connected with first vulcanized rubber blocks evenly distributed in a circular shape. A first groove body is penetrated and opened at the upper end of the integrated structure formed by the support seat and the base. The upper end of the first vulcanized rubber block is fixedly connected with a protection plate. The four corners of the upper end of the protection plate are fixedly connected with first limiting columns. A second groove body is penetrated through the center of the upper and lower ends of the protection plate. Through the multiple first vulcanized rubber blocks on the support seat, the protection plate can quickly rebound when descending. The second elastic component can be limited through the second groove body.

[0009] Preferably, limiting grooves are penetrated and opened at the four corners of the upper and lower ends of the upper stamping plate. The limiting grooves are adapted to the first limiting columns. Through the first limiting columns, the stamping oil cylinder can work more stably.

[0010] Preferably, two first groove bodies on the same side at the front and rear ends of the base are respectively connected to the ventilation groove in a through manner. The connecting pipe communicates with the first groove body. The air in the connecting pipe and the first groove body can be sealed and protected from air through an air pump, which is convenient for the subsequent vibration blanking work of the second elastic component.

By turning on the air pump, when the rubber column moves downward along the inner wall of the first groove body, the air in the first groove body is discharged through the air pump on the communicating pipe. Then, after the stamping work of the upper stamping plate is completed, the upper stamping plate moves upward, and the lower stamping plate cannot move due to the negative pressure generated by the rubber column on the inner wall of the first groove body. Then, by turning on the air pump, the gas enters the first groove body, so that the cross is quickly rebounded under the reaction of the spring and the second vulcanized rubber block, so as to shake out the object after the upper stamping of the lower stamping plate, thus realizing the work of rebounding and blanking, and solving the problem of manual blanking that requires manual use of tools.

[0012] Preferably, a fixed column is fixedly connected to the upper end of the base, a first electric cylinder is arranged on the fixed column, and the right end of the telescopic rod of the first electric cylinder is fixedly connected to a push block. When blanking work needs to be carried out, by turning on the first electric cylinder, the telescopic rod of the first electric cylinder drives the push block to push out and blank the stamped object on the upper end of the protection plate.

[0013] Preferably, the lower end of the push block is flush with the upper end of the protection plate. After the stamped object is shaken, it will fall above the lower stamping plate and the protection plate, which is convenient for subsequent blanking work.

[0014] The beneficial effects of the present utility model:

[0015] 1. The lower stamping plate is stamped by the upper stamping plate. At the same time, the cross below the lower stamping plate will move downward, and then the rubber column will move downward along the inner wall of the first groove body. By turning on the air pump, when the rubber column moves downward along the inner wall of the first groove body, the air in the first groove body is discharged through the air pump on the communicating pipe. Then, after the stamping work of the upper stamping plate is completed, the upper stamping plate moves upward, and the lower stamping plate cannot move due to the negative pressure generated by the rubber column on the inner wall of the first groove body. Then, by turning on the air pump, the gas enters the first groove body, so that the cross is quickly rebounded under the reaction of the spring and the second vulcanized rubber block, so as to shake out the object after the upper stamping of the lower stamping plate, thus realizing the work of rebounding and blanking, and solving the problem of manual blanking that requires manual use of tools.

[0016] 2. By activating the first electric cylinder, the telescopic rod of the first electric cylinder drives the push block to push out and discharge the object after stamping at the upper end of the protection plate, solving the problem that when manually discharging, it is necessary to frequently contact the stamping equipment and the mold, which poses a safety hazard.

[0017] 3. By using vulcanized rubber blocks, vulcanized rubber has better strength and hardness, making it more wear-resistant and durable. Moreover, the rubber elasticity is enhanced compared with ordinary rubber, and it can better withstand deformation without easily failing, which can increase the service life of the spring-back assembly.

When the upper stamping plate 11 contacts the second elastic return component, the first elastic return component and the second elastic return component descend to perform stamping work. Then, the stamping cylinder 10 is activated to drive the upper stamping plate 11 to move upward, so that the first elastic return component rebounds. The second elastic return component remains stationary through the connecting pipe 8. Then, the connecting pipe 8 is opened to enable the second elastic return component to perform rapid rebound work, thus vibrating out the stamped object on the lower stamping plate 201. Then, the lower stamping plate 201 returns to its original position through the second vulcanized rubber block 104. Then, by activating the first electric cylinder 5, the push block 6 on the first electric cylinder 5 is driven to push the object on the lower stamping plate 201 for discharging work, thus realizing the elastic return and discharging work, and solving the problem that some existing stamping devices still require manual use of tools for manual loading and unloading, and frequently contact the stamping equipment and molds, posing potential safety hazards.
