Block, pull bar, spring, handle, base are fixed in lower template, and active positioning block passes through base by screwed pull bar, living
Dynamic locating piece bottom is embedded in the locating slot made in lower template, and slidably and can be accurately positioned in groove, and spring is worn
Cross pull bar and be arranged between active positioning block and base；Guider, which is located on rear side of mould, ensures punching gap.
The application method of the die cutting die comprises the following steps：First, upper and lower membrane module is respectively mounted and is fixed on punch press
Top shoe and lower table face on, and adjust punching machine stroke；Second, the handle of lateral register device is pulled, in termination locator
The part that both sides carry surplus is placed in left part, right part is placed through after being punched for the first time while with surplus
Part, it is ensured that release handle after part former topographies, part be accurately positioned and clamped in advance；3rd, start
Punch press, upper die component is descending by the power of punching apparatus, holding pad to part carry out vertical direction compression, upper die component after
Continuous descending, formpiston Blank cutting-edge and former Blank cutting-edge collective effect once complete the accurate punching of two collar part terminations.
The application utilizes the general principle of punch process, realizes that " several " font sheet metal part is inexpensive, efficient essence
Quasi- punching, has general applicability to collar class part termination " going surplus " processing.
The application is described in further detail below in conjunction with drawings and Examples.
