Machining die for steel strip open-type lock catch for package

Abstract

The invention belongs to the technical field of machining of lock catches for cold-rolled strip package and particularly relates to a machining die for a steel strip open-type lock catch for package. The machining die comprises an upper die assembly, a lower die assembly, a material pushing device and two upper die lifting guide column devices, wherein the upper die assembly consists of an upper die plate, a dip mold base, a punching and shearing die, a punching pressure plate, two extrusion block bases, two inclined extrusion blocks and a reciprocating lifting pressure plate; the lower die assembly comprises a lower die plate, a base plate, a lower molding die base, a left concave die block, a left movable punching die I, a left movable punching die II, a right concave die block, a right movable punching die I, a right movable punching die II, a feeding cover plate and a locating baffle; the two inclined extrusion blocks are respectively and slidably connected with the left movable punching die I, the right movable punching die I, the left movable punching die II, and the right movable punching die II. The machining die is capable of finishing continuous production processes such as feeding, punching, press molding, dimpling and discharging of steel strip latch catches for package only by use of one punching machine, greatly lowering the equipment investment volume and improving the productivity.

Description

technical field [0001] The invention belongs to the technical field of cold-rolled steel strip packing lock processing technology, and in particular relates to a processing mold for packaging steel strip open lock buckles. Background technique [0002] In the production process of the steel belt open lock for packaging, the steel belt lock is an important part to lock the tail of the steel belt. The structure of the steel belt lock is to fold the two ends of a section of steel belt into a flat long ring buckle. The processing method is generally produced by a stamping die on a press. Since the structure needs several times of bending and forming to complete, in the conventional production process, generally several sets of stamping dies or several presses are required to meet the production requirements. Not only the production cycle is long , and requires a lot of equipment, occupies a large area, and wastes manpower and material resources. Contents of the invention [0...
