Abstract

The utility model relates to a quickly installed punch and sleeve combination for an automobile punching die. A punch is connected with a punch fixing plate in a threaded manner. When damaged, the punch is connected with a sleeve matched with the punch and is detached without detaching a pressing plate of the whole die. The quickly installed punch and sleeve combination is characterized in that four axial punch grooves are evenly arranged in a rod body in the middle of the punch, four axial sleeve flanges are evenly arranged on the inner wall of the sleeve matched with the punch, and the punch is fixed by matching the punch grooves with the sleeve flanges and then is detached and installed. The quickly installed punch and sleeve combination is simple in structure, convenient to operate and particularly suitable for quickly replacing the punch with poor rigidity on a large complicated die, time can be saved, and production efficiency is improved.

Description

The fast-assembling drift and the sleeve that are used for the automobile diel
Technical field
The utility model relates to an automobile changing punching die quickly plunger mechanism, specifically is a kind of fast-assembling drift and sleeve that is used for the automobile diel.
Background technology
At present, the drift of stamping parts of automobile punching die widespread usage is installed on the drift fixed head, and the drift fixed head is installed on the mold and punching head seat through 1 pin, 2 bolts.If drift damages, need earlier mould is withdrawed from lathe, with driving mould is hung the maintenance area, holding pad is unloaded after opening mould, drift is unloaded from the drift fixed head, change new drift; The installation mold holding pad with mould closes, reinstalls on the lathe then, could continue to produce.If mould structure is simple, about 2.5 hours of whole process need; If mould structure is complicated,, then need at least 6 hours time such as the big beam form of truck.Delay production, also increased working strength of workers.
The utility model content
The problem long to the existing mold drift replacing time and labor strength is big; The utility model provides a kind of quickly replacing mould plunger mechanism; The drift replacing time is shortened greatly, only need about 15 minutes, and also well reduced working strength of workers.
The technical scheme that the utility model adopted is:
The fast-assembling drift that is used for the automobile diel, said fast-assembling drift is installed in the screwed hole of drift fixed head 1 through the drift screw rod 2.2 of drift body 2 upper ends, and the drift working position 2.3 of drift body 2 lower ends is positioned at the drift via hole of mould holding pad; Improvement is: be equipped with four axial drift grooves 2.1 on the shaft at drift body 2 middle parts of said drift.
With the matching used sleeve of the said fast-assembling drift of claim 1; Be equipped with four axial sleeve flanges 3.1 on the inwall of said sleeve 3, the drift groove 2.1 on the shaft at sleeve flange 3.1 and drift body 2 middle parts is used; Sleeve 3 lower ends are cylindric, and available common wrench is carried out installation or removal.
The diameter of the drift via hole of said mould holding pad is greater than sleeve 3 external diameter 6-10mm.
Air line distance is than the little 3-5mm of air line distance between two parallel sleeve flanges 3.1 of sleeve inner between two parallel drift grooves 2.1 of said drift.
The utility model is simple in structure, is convenient to operation, is particularly suitable on the large complicated mould the bad drift of rigidity and changes fast, can save time, and enhances productivity.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the front view of drift.
Fig. 3 is that the K of Fig. 2 is to view.
Fig. 4 is the cutaway view of sleeve.
Fig. 5 is Fig. 4 vertical view.
Among the figure, 1. drift fixed head, 2. drift body, 2.1. drift groove, 2.2 drift screw rods, 2.3 drift working positions, 3. sleeve, 3.1 sleeve flanges.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done explanation further through embodiment.
Embodiment:
The utility model relates to the drift and the sleeve of automobile diel; The fast-assembling drift is installed in the screwed hole of drift fixed head 1 through the drift screw rod 2.2 of drift body 2 upper ends, and the drift working position 2.3 of drift body 2 lower ends is positioned at the drift via hole of mould holding pad; Improvement is: be equipped with four axial drift grooves 2.1 on the shaft at drift body 2 middle parts of said drift.Air line distance L1 is than the little 5mm of air line distance L2 between two parallel sleeve flanges 3.1 of sleeve inner between two parallel drift grooves 2.1 of drift, and drift and sleeve could more convenient being used like this.Drift working position 2.3, hole size is as required processed quenching.Also be provided with and the matching used sleeve 3 of fast-assembling drift; Be equipped with four axial sleeve flanges 3.1 on the inwall of said sleeve 3, the drift groove 2.1 on the shaft at sleeve flange 3.1 and drift body 2 middle parts is used; Sleeve 3 lower ends are cylindric, and available common wrench is carried out installation or removal.The sleeve outer wall diameter need be than the little 6mm of drift via diameter of mould holding pad, and sleeve could drift for convenience detach like this.
When dismounting or installation drift; Sleeve 3 is stretched into from mould holding pad drift via hole, drift groove 2.1 and sleeve flange 3.1 section aligned are inserted in, use common wrench to be rotated then; With dismounting in the screwed hole of drift from the drift fixed head or install, carry out the quick replacing of drift.
