Description

Technical Field

[0001] This utility model relates to a stamping machine, specifically an automated stamping machine for machining, belonging to the field of machining technology. Background Technology

[0002] Machining is a process that uses mechanical processing equipment to cut and shape workpieces to obtain the required shape, size and precision. When the production demand is large batch, high precision and the workpiece shape is relatively regular (such as sheet metal stamping parts), automated stamping machinery will be widely used to improve production efficiency, reduce labor costs and ensure processing consistency.

[0003] The existing utility model with authorization announcement number CN221493817U discloses a mechanical processing stamping device. Through the cooperation of a stamping die base, a groove, a spring, a sliding plate, and a push block, the formed sheet metal enters the groove during the stamping process and applies force to the push block and sliding plate, compressing the spring. After stamping, the spring rebounds, pushing the sliding plate and push block back to their original positions, lifting the formed sheet metal from the groove to the surface of the stamping die base. Then, through the cooperation of a mounting rod, a horizontal plate, a first rack, a slide, a blanking push plate, a second rack, a mounting base, and gears, the hydraulic cylinder retracts after stamping. During the retraction process, the first rack meshes with the gear, causing it to rotate. At the same time, the gear meshes with the second rack, causing the blanking push plate to move. During the movement, the blanking push plate pushes the formed sheet metal part on the top of the stamping die base to complete the blanking. No manual blanking is required, resulting in higher work efficiency.

[0004] While the above technical solution eliminates the need for manual material handling and increases work efficiency, it also makes mold replacement inconvenient, lacking a convenient mold replacement structure. This results in poor mold replacement convenience and overall limited versatility and ease of use for the stamping machine. Therefore, this paper proposes an automated stamping machine for machining.

[0019] Please refer to this carefully. Figure 1 , Figure 3 , Figure 4 and Figure 5 Each guide rod 606 has a buffer spring 607 fitted on its outer surface. The two ends of each buffer spring 607 are in contact with the bottom surface of the lifting frame 4 and the upper surface of the top shell 605, respectively.

[0021] When using this utility model: First, according to the specifications of the workpiece, the disassembly and assembly base 602 of the corresponding bottom mold 603 is fixed in the bottom shell 601 by the first hand-tightening positioning bolt 604.

[0022] The workpiece to be processed is placed on the bottom mold 603. The button controller 5 sends a command, and the hydraulic rod 3, which is electrically connected to the button controller 5, is activated. The telescopic end of the hydraulic rod 3 drives the lifting frame 4 to move downward. The lifting frame 4 drives the top shell 605 and the top mold 609 to move downward synchronously through the guide rod 606, gradually approaching the workpiece and performing the stamping operation.

[0023] During the stamping process, the guide rod 606 slides along the lifting frame 4. The buffer spring 607, which is sleeved outside the guide rod 606, is compressed and generates elastic force to buffer the impact force of the top die 609 on the workpiece, reduce damage to the die and the workpiece, and ensure processing accuracy. The support column 7 and the support plate 8 enhance the overall stability of the equipment and prevent shaking during stamping. In order to increase the stamping accuracy, clamping structures for different workpieces to be stamped can also be pre-installed on both sides of the bottom die 603.

[0024] After processing, the hydraulic rod 3 is retracted by the button controller 5, and the lifting frame 4 drives the top mold 609 to reset upward. The operator can then remove the processed workpiece. If it is necessary to change the processing specifications, simply loosen the first hand-tightened positioning bolt 604 and the second hand-tightened positioning bolt 610 to quickly replace the corresponding bottom mold 603 and top mold 609, thereby improving the equipment's versatility and efficiency. The design of the entire automated stamping machine effectively solves the problems of poor mold replacement convenience and poor versatility and convenience of the entire stamping machine due to the lack of a convenient mold replacement structure.
