A stamping and blanking equipment modified based on layout plan and its operation method

Abstract

The invention relates to the technical field of punching processes, in particular to punching and blanking equipment modified based on a layout scheme and an operation method thereof. The punching andblanking equipment modified based on the layout scheme comprises a worktable; support legs are arranged at the bottom of the worktable; a press is fixed on the worktable through a bracket; a punch ofthe press is connected with a blanking convex mold; the worktable is provided with a blanking concave mold corresponding to the blanking convex mold; the bottom of the blanking concave mold is connected with a rotating device; blanking channels are formed in the blanking concave mold and the rotating device; the rotating device is connected with a rotating sleeve; a connecting plate is arranged on the outer surface of the rotating sleeve; an extension cylinder is arranged on the lower surface of the worktable; and a connecting rod is hinged between a piston rod of the extension cylinder and the connecting plate. The equipment can improve the material utilization rate and save the cost.

Description

technical field [0001] The invention relates to the technical field of stamping technology, in particular to a stamping blanking equipment modified based on a nesting scheme and an operation method thereof. Background technique [0002] The process of separating the sheet material along the closed contour line and using the material within the contour line as a blanking part is called blanking, and the mold that completes the blanking process is called blanking die. [0003] At present, the blanking dies in production on the market are all "single-row" nesting with low material utilization rate. For stamping parts, the material cost accounts for more than 60% of the total cost. The low material utilization rate directly leads to the failure of the project. The cost rises sharply, the greater the output, the more serious the impact of the utilization rate on the cost, which is difficult to make up for in other links, and the utilization rate of double-row layout can usually b...

[0003] At present, the blanking dies in production on the market are all "single-row" nesting with low material utilization rate. For stamping parts, the material cost accounts for more than 60% of the total cost. The low material utilization rate directly leads to the failure of the project. The cost rises sharply, the greater the output, the more serious the impact of the utilization rate on the cost, which is difficult to make up for in other links, and the utilization rate of double-row layout can usually be increased by 10 percentage points. Therefore, double-row layout is used for blanking. It is of great significance to save material costs
