Sectional trimming mould

Abstract

The invention discloses a sectional trimming mould and relates to a stamping mould. The sectional trimming mould comprises an upper mould base, a lower mould base and a mould handle, wherein a trimming concave mould is arranged on an upper surface of the lower mould base; trimming convex moulds are respectively arranged on the two sides of the trimming concave mould; the cutting edges of the two trimming convex moulds are different in height; the trimming convex moulds are in sliding connection with the upper surface of the lower mould base through slide blocks; a sloped plane is arranged at one end of each slide block away from the trimming concave mould; tapered wedges matched with the sloped planes of the slide blocks are respectively arranged on the lower surfaces on the two sides of the upper mould base; guiding blocks are respectively arranged in the positions on the two sides of the upper surface of the lower mould base corresponding to the tapered wedges; one end of each slide block away from the trimming concave mould is moveably connected with the corresponding guiding block through a reset bolt; reset rubber pads are sleeved on the reset bolts. The sectional trimming mould can be used for finishing the different-height trimming for the two sides of a box-shaped part at one step, the working efficiency is high, the repeated positioning is avoided and the precision of the products is increased.

Description

technical field [0001] The invention relates to a stamping die, in particular to a segmented trimming die. Background technique [0002] Deep drawing is a common machining process, which is a stamping forming process for making cup-shaped parts with flat slabs, also known as drawing. Hollow parts with cylindrical, spherical, conical, box-shaped, stepped, flanged and other complex shapes can be made by deep drawing. Its forming is generally completed by drawing dies. After the drawing parts are formed, there will generally be uneven lugs at the mouth, which need to be trimmed. Existing drawing parts are generally trimmed by using trimming dies. For some large box-shaped parts, sometimes it is necessary to cut the two sides to different heights. Using the existing trimming die, only one side can be cut first, and then the workpiece is taken out, rotated 180 degrees and adjusted the position of the workpiece to cut the other side. In this way, the processing efficiency is low...

Its forming is generally completed by drawing dies. After the drawing parts are formed, there will generally be uneven lugs at the mouth, which need to be trimmed. Existing drawing parts are generally trimmed by using trimming dies. For some large box-shaped parts, sometimes it is necessary to cut the two sides to different heights. Using the existing trimming die, only one side can be cut first, and then the workpiece is taken out, rotated 180 degrees and adjusted the position of the workpiece to cut the other side. In this way, the processing efficiency is low, and repeated positioning is required, which affects the accuracy of the product
