Description

Without the fixedly unloading type blanking die that leads

Technical field

The utility model relates to technical field of mold, particularly without the fixedly unloading type blanking die that leads.

Background technology

Since reform and opening-up, along with the high speed development of national economy, market constantly increases the demand of mould.In recent years, mould industry is always fast-developing with the growth rate of 15% left and right, and great variety has also occurred the ownership composition of mould industry enterprise, except state-owned professional mould factory, and collective, joint, individual proprietorship and be privately also developed rapidly.In recent years many Mould Enterprises have strengthened the dynamics of investment for technological progress, technological progress are considered as to the important motivity of enterprise development.Some domestic Mould Enterprises have been popularized two-dimentional CAD, and bring into use successively the international softwares such as UG, Pro/Engineer, I-DEAS, Euclid-IS.

Mould is one of technological equipment important during modern industry is produced, and in the production industries such as casting, forging, punching press, plastics, rubber, glass, powder metallurgy, pottery, is used widely.In recent years, the mould industry of China has also had larger development, and mold production process and the intelligent degree of production equipment are more and more higher, has greatly improved the accuracy of manufacture, quality and the productivity ratio of mould.

Existing metal plate punching part is mainly to utilize mould to complete the processing of various shapes, blanking die is modal a kind of mould in cold stamping process, during blanking, with forcing press, promote patrix and carry out blanking punched, traditional blanking die structure complexity, operating technology level is had relatively high expectations, the quality of fit of die and punch is difficult to control, because pressure is excessive, flitch is easy to damage, and the waster rate of blank is high, and easily causing die and punch serious wear, maintenance cost is high.

Utility model content

The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of simple to operate, product quality is high and maintenance cost is low without the fixing unloading type blanking die of guiding.

The purpose of this utility model is achieved through the following technical solutions: without the fixedly unloading type blanking die that leads, it comprises upper bolster, punch, die shoe and die, center, upper bolster top is connected with die shank, die shank is connected with external pressure machine, punch is fixed by screws in the below of upper bolster, and locates by least two alignment pins; The top of die shoe is installed with die and stripper successively from bottom to up, is provided with the material-dropping hole suitable with punch on die.

The rear side of described die is also provided with pin stop.

Described pin stop is for rewinding formula pin stop.

The utlity model has following advantage:

1, of the present utility model simple in structure, at the rear side of die, pin stop is set, the spacing of feed direction completes by pin stop, reduces operation easier, to operating personnel's technical merit, requires lower.

2, between punch and upper bolster, by two alignment pins, position, die and stripper are also fixed on die shoe, and die coordinates with punch precisely, and blanking precision is high, and the quality of product is good.

3, die coordinates with punch, and die and punch friction are little, and die and punch are not fragile, have significantly reduced the maintenance cost of mould.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the plan structure schematic diagram that die shoe coordinates with die;

Fig. 3 is A-A sectional structure schematic diagram in Fig. 2;

In figure: 1-upper bolster, 2-punch, 3-die shoe, 4-stripper, 5-die, 6-pin stop, 7-material-dropping hole, 8-die shank.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.

As shown in Figure 1, without the fixedly unloading type blanking die that leads, it comprises upper bolster 1, punch 2, die shoe 3 and die 5, upper bolster 1 center, top is connected with die shank 8, die shank 8 is connected with external pressure machine, punch 2 is fixed by screws in the below of upper bolster 1, and locates by least two alignment pins; The top of die shoe 3 is installed with die 5 and stripper 4 successively from bottom to up, is provided with the material-dropping hole 7 suitable with punch 2 on die 5.

The rear side of described die 5 is also provided with pin stop 6.

Described pin stop 6 is for rewinding formula pin stop.

The course of work of the present utility model is as follows: punch 2 and die shank 8 are fixedly connected into one structure, and locate with alignment pin.Die shank 8 is connected with external pressure machine, before blowing, die shank 8 is promoted to peak, the minimum point of punch 2 is higher than the peak of die 5, blank material is placed between die 5 and stripper 4, the front end of blank material withstands on pin stop 6, the spacing of feed direction is completed by pin stop 6, and after blank material is fixing, die shank 8 drives punch 2 to move down, die 5 is coordinated with punch 2, complete blanking, blank is from material-dropping hole 7 to dropping material, and die shank 8 drives on punch 2 and moves, blank material is blocked by stripper 4, and punch 2 departs from blank material.
