Description

Technical Field

[0001] The utility model relates to the technical field of workpiece stamping, in particular to an adjustable stamping device. Background Art

[0002] Workpiece production can be done by forging, welding, stamping and other processing methods. The current stamping process generally uses a stamping device to apply external force to the workpiece through a punch and a die to cause plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size.

[0003] For example, Chinese patent CN117619971A discloses a stamping device, including a workbench, a driving mechanism, a stamping mechanism, a clamping mechanism and a linkage mechanism; the driving mechanism includes a guide column, a mounting seat and a driving member, the guide column is connected to the workbench, the mounting seat is slidably arranged on the guide column, the driving member is arranged on the guide column and connected to the mounting seat, and the driving member is used to drive the mounting seat to slide along the guide column; the stamping mechanism is connected to the mounting seat; the clamping mechanism is slidably arranged on the workbench, and the clamping mechanism is used to clamp the workpiece; the linkage mechanism is respectively connected to the mounting seat and the clamping mechanism, and when the mounting seat slides along the guide column, the clamping mechanism is driven to slide on the workbench through the linkage mechanism, so that the workpiece clamped by the clamping mechanism moves to a position corresponding to the stamping mechanism that moves synchronously with the mounting seat, so that the stamping mechanism stamps the workpiece. The stamping device of the present application prevents operators from entering the stamping area of ​​the punch when changing the workpiece by arranging the clamping mechanism outside the stamping area of ​​the stamping mechanism, thereby improving production safety.

[0004] However, the stamping device cannot adjust the angle of the workpiece. When producing a workpiece with evenly distributed stamping parts around it, the workpiece needs to be rotated manually, which is very dangerous and reduces the workpiece production efficiency. During stamping, it is also impossible to accurately position the workpiece, which easily leads to a reduction in the precision of workpiece production.

[0005] Based on this, the utility model designs an adjustable punching device to solve the above problems. Utility Model Content
