Description

The fine-edge blanking mould bases

One, technical field

The utility model relates to a kind of press machine accessory, and the fine-edge blanking mould bases of using on especially a kind of press machine belongs to the stamping-out technical field.

Two, background technology

The stamping-out mould bases is the Last main accessory of press machine, it is at present domestic that to be used for carrying out the fine-edge blanking press machine all be import mostly, it is to adopt the three-dimensional operating pressure machine more than 100 tons to produce, its product processed will be released in die, process one and release one, production efficiency is low, and it costs an arm and a leg, about 5,000,000 yuan of the price of every Bench mould support has increased the price of the production cost and the finished product of stamping-out.

Three, the content of utility model

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and a kind of production efficiency height and the low fine-edge blanking mould bases of price are provided.

For achieving the above object, the utility model is achieved in that a kind of fine-edge blanking mould bases, mainly comprise the corresponding with it bottom plate of mounting plate, be loaded on the punch on the mounting plate and be loaded on die on the bottom plate, its special character is, the intrinsic unsteady die shank on the top of mounting plate, punch is equipped with in the bottom, is provided with four guide pin bushings of symmetrical distribution in the mounting plate, intrinsic two springs below mounting plate; Four guide pillars are housed on the bottom plate, insert respectively in its corresponding guide pin bushing the upper end of guide pillar, between guide pillar and the guide pin bushing ball is housed, intrinsic and die on the bottom plate, the profile of tooth pressure coil that is slidingly matched with it is housed on the die, the polyurethane rubber plate is equipped with in the top of profile of tooth pressure coil, and four cushions of symmetrical distribution are housed between profile of tooth pressure coil and the die.

Above-mentioned fine-edge blanking mould bases also can be designed to the upper and lower supporting plate action of hydraulic control, is respectively equipped with a hydraulic jack and is attached thereto a logical oil circuit in mounting plate and bottom plate.

The utility model compared with the prior art, used press machine is to process after improving with 35 tons ordinary press process, the fine-edge blanking mould bases is to adopt bidirectional-movement to carry out stamping-out, and the product that processes can directly be folded out downwards in die, and need not in die, release, improved production efficiency, the product that processes is still all suitable with the product of producing with the import mould bases on smooth durable at dimensional accuracy, but its price is significantly less than the import mould bases, it only is 1/50th of its price, reduced production cost and product price, the substituting import one accessory is economical and practical fully.

Four, description of drawings

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

Fig. 2 adopts the structural representation of hydraulic control for the utility model.

Five, the specific embodiment

For understanding the utility model better, it is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1, fine-edge blanking mould bases described in the utility model mainly is by mounting plate 10 and corresponding with it bottom plate 17, is loaded on the punch 12 on the mounting plate and is loaded on die 15 on the bottom plate etc. and constitute, at the top of mounting plate 10 screw 8 intrinsic unsteady die shanks 9, punch 12 is equipped with in the bottom, be provided with four guide pin bushings 6 of symmetrical distribution in the mounting plate 10, spring shaft 7 intrinsic two springs 11 by passing mounting plate below mounting plate 10; Four guide pillars 4 are housed on bottom plate 17, insert respectively in its corresponding guide pin bushing 6 upper end of each guide pillar 4, between guide pillar 4 and the guide pin bushing 6 ball 5 is housed all, on bottom plate 17, pass through screw 1 intrinsic die 15, die 15 is by being equipped with the profile of tooth pressure coil 14 that is slidingly matched with it on unit's pin 3, polyurethane rubber plate 13 is housed above profile of tooth pressure coil 14, four cushions 16 of symmetrical distribution are housed between profile of tooth pressure coil 14 and the die 15.

Above-mentioned fine-edge blanking mould bases, upper and lower supporting plate also can adopt hydraulic control, as shown in Figure 2, be provided with hydraulic jack 18 and be attached thereto logical oil circuit 19 at mounting plate 10, in bottom plate 17, be provided with hydraulic jack 20 and be attached thereto logical oil circuit 21, intrinsic oil cylinder lower cover 22 below hydraulic jack 20.

The fine-edge blanking mould bases is installed on the lathe, when feed appliance is brought roll bending 2, lathe drives the die shank 9 that floats to lower slider, spring 11 and polyurethane rubber plate 13 are suppressed jointly on profile of tooth pressure coil 14, roll bending is pressed near the cutting edge of die, punch glides, the two pressure of punch and profile of tooth pressure coil are clamp-oned roll bending and are formed part in the matrix cavity, mounting plate is return then, the profile of tooth pressure coil is upspring by cushion, and feed appliance is seen the roll bending waste material off, sends roll bending to be processed again here, repeat said process and carry out stamping-out, the product of going out in the matrix cavity one by one marshalling directly come out downwards, and need not in matrix cavity, eject one by one, improved production efficiency greatly, convenient and swift, economical and practical.
