CN2902517Y - Fast changing device of punching press mould - Google Patents

Abstract

The utility model relates to an extrusion die fast changing device, wherein the fast changing board is positioned in the installation groove above the upper die backer and provided with a function feed-through corresponding to the inoperative terrace die. The fast changing board is designed according to the shape of the needed product and the theory that the operative terrace die is blocked while the inoperative terrace is in the air. During the extrusion of the die, on the part without holes on the fast changing board the terrace die works under the press of the changing board to function as blanking, while on the part with the feed-through on the fast changing board the terrace die contacts the material band, is forced, and projects upwards crossing the feed-through not functioning as blanking. The utility model has the advantages that different fast changing boards are chosen according to different products, thereby avoiding wrong installation, saving changing time, and improving operating efficiency greatly.

Description

A kind of apparatus for changing punching die quickly

Technical field

The utility model relates to mechanical manufacturing field, is a kind of apparatus for changing punching die quickly specifically.

Technical background

At present, flexible and changeable along with market, various Production of Stamping Die producer has released the novel diel structure of the corresponding multiple product of a mold one after another.Yet, when this diel behind the intact a kind of product of punching press, when the another kind of product of the same serial different size of punching press, must take mould apart, change numerous punch.But the process that this punch is changed is not only loaded down with trivial details, makes mistakes easily, has also taken the too much production time.

Summary of the invention

For the problem that the loaded down with trivial details and operating mistake that overcomes in the above-mentioned mould punch replacing process is produced, the utility model provides a kind of apparatus for changing punching die quickly.This device need not be changed punch, only needs the transposing quick-changing plate, just can make mould realize production to another kind of stamping products at once.

The technical solution of the utility model is:

Be provided with mounting groove above upper bolster, the quick-changing plate corresponding with producing product is contained in the mounting groove, and the function through hole corresponding with the inoperative punch arranged on the quick-changing plate.The punch corresponding with producing product is contained on the mould.

When a certain product of punching press, install the quick-changing plate corresponding with this product.In the mould punching course, do not have the place of function through hole on quick-changing plate, punch is changed plate pressure and is worked, and plays the stamping-out effect; In quick-changing plate the place of function through hole is arranged, punch contacts stressed with strip, upwards lift, and passes the functional hole position that plate is changed in the top, does not play the stamping-out effect.Like this,, select different quick-changing plate, be implemented in and change production under the situation of not changing punch apace according to different products.Therefore, use the utility model, can avoid loading error, save the replacing time, significantly increase work efficiency.

Description of drawings

Fig. 1 is the schematic diagram of the present utility model that a kind of quick-changing plate has been installed.

Fig. 2 is the transposing schematic diagram of the present utility model of quick-changing plate down.

Fig. 3 is the schematic diagram of the present utility model that another kind of quick-changing plate has been installed.

The specific embodiment:

Fig. 1-3 has represented the operation principle and the replacing process of the utility model quick replacement device.

Embodiment 1: as shown in Figure 1: the expression punching press is with the old product of circle and the incompatible signal of triangle sets.On upper bolster [2], mill out groove, in groove, load onto the quick-changing plate corresponding with old product, quick-changing plate designs according to the principle of shape of product and " punch of work is blocked; the punch of inoperative is fallen through ", and then the punch that will use in these series of products all is installed on the mould.In at this moment each punching course, behind punch [10] [11] [12] the contact strip [6], punch [10] and [12] are subjected to the pressure of quick-changing plate [1] and work, and stamp out circle and leg-of-mutton shape of product feature on strip [6]; Punch [11] the then function through hole from quick-changing plate [1] passes, and is not subjected to its pressure, therefore not punching press strip [6].

As shown in Figure 2: expression only need be backed out soket head cap screw [15] when needs punching press new product, take the quick-changing plate [1] of old product, and all punch are not changed.

As shown in Figure 3: the new product that the expression punching press is illustrated with circle and square combination.Changed the another kind of quick-changing plate [1 '] corresponding this moment with new product, in each punching course, behind punch [10] [11] [12] the contact strip [6], punch [10] and [11] are subjected to the pressure of quick-changing plate [1 '] and work, and stamp out circle and foursquare shape of product feature on strip [6]; Punch [12] the then function through hole from quick-changing plate [1 '] passes, and is not subjected to its pressure, not punching press strip [6].

Embodiment 2: a kind of apparatus for changing punching die quickly; Comprise upper bolster [2], convex mould pad [3], punch retainer [4], stripper [5], strip [6], concave template [7], die backing plate [8], die shoe [9], punch [10], punch [11], punch [12], punch cushion cover [13], force-transmitting pole [14] and soket head cap screw [15], be provided with mounting groove in upper bolster [2] top, the quick-changing plate [1] corresponding with producing product is contained in the mounting groove, the function through hole corresponding with the inoperative punch arranged on the quick-changing plate [1], and punch [10], [11], [12] corresponding with producing product are contained on the mould.
