The utility model content
The purpose of the utility model is to overcome the deficiency of prior art; A kind of active force of exerting pressure on can cushion pressing automobile rear muffler housing the time between mould and the following pressure-bearing mould is provided, and then the mechanism of protection mould during the automobile rear muffler housing punching press interlock that can protect mould.
The purpose of the utility model mainly realizes through following technical scheme: the mechanism of protection mould during automobile rear muffler housing punching press interlock; Comprise positioning seat, following positioning seat and upper plunger; Said positioning seat down is arranged on the positioning seat below; The upper surface of following reservation is provided with positioning pipe, and the lower surface of last positioning seat is provided with the tube connector corresponding with the positioning pipe position, and the upper end of said upper plunger embeds in the tube connector and with tube connector and forms interference fit; The lower end of upper plunger is corresponding with positioning pipe size coupling and position, is provided with pressure buffer mechanism in the said positioning pipe.
Said pressure buffer mechanism comprises down bearing plate, goes up bearing plate and many springs, and the two ends of said spring are connected with last bearing plate with following bearing plate respectively, and the said bearing plate that descends is connected down on the positioning seat.
Tube connector of the utility model and last positioning seat and positioning pipe and following positioning seat all can independently exist; Mode through welding connects again; In order to strengthen the bonding strength between tube connector and last positioning seat and positioning pipe and the following positioning seat, and be convenient to manufacture, as preferably; Said tube connector and last positioning seat become one, and said positioning pipe becomes one with following positioning seat.
Compared with prior art, the utlity model has following beneficial effect: the utility model comprises positioning seat, following positioning seat and upper plunger, wherein; The upper surface of following reservation is provided with positioning pipe, and the lower surface of last positioning seat is provided with the tube connector corresponding with the positioning pipe position, and the upper end of upper plunger embeds in the tube connector; The lower end of upper plunger is corresponding with positioning pipe size coupling and position, is provided with pressure buffer mechanism in the positioning pipe, and the utility model overall structure is simple; Be convenient to realize; And the utility model is gone up when using on the connecting plate that positioning seat is connected the mould of exerting pressure on fixing, and following positioning seat is connected on the connecting plate of fixing pressure-bearing mould down, when on exert pressure mould during near pressure-bearing mould down; The upper plunger of the utility model embeds in the positioning pipe; And cushioning the active force of exerting pressure between mould and the following pressure-bearing mould under the effect of pressure buffer mechanism, and then the active force of exerting pressure between mould and the following pressure-bearing mould is descended gradually, and then can effectively protect exert pressure mould and following pressure-bearing mould.
