Abstract

The invention relates to a punch mould quick-changing device and relative producing method, while the convex die used in said serial products are all mounted on the mould. Wherein, a groove is milled on the upper mould base above the convex mould to arrange quick-changing plate; when punching one product, mounting a quick-changing plate relative to said product; in the process of punching mould, at the part without hole on the quick-changing plate, the convex mould via the pressure of said plate can punch; and at the part with hole of quick-changing plate, the convex mould contacts material belt to be uplifted and via the hole of upper quick-changing plate, they can not punch; therefore, different quick-changing plates can be selected according to different products, to change product line without changing convex mould; and said quick-changing plate is designed according to the product shape and the theory that the working convex mould is baffled and the free convex mould is idle.

Description

A kind of apparatus for changing punching die quickly and manufacture method

Technical field the present invention relates to a kind of apparatus for changing punching die quickly and the manufacture method of diel when the multiple different product of punching press, belongs to the machine die field.

Technical background is present, flexible and changeable along with market, and 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 wasted the production time greatly.

Summary of the invention the invention provides a kind of apparatus for changing punching die quickly and manufacture method in order to overcome the deficiency loaded down with trivial details and that make mistakes and brought easily in the above-mentioned mould punch replacing process.This device need not be changed punch, as long as by corresponding quick-changing plate in the quick replacement device is simply changed, just can make mould realize production to another kind of stamping products at once.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of manufacture method of apparatus for changing punching die quickly comprises following steps;

Step 1: make quick-changing plate, feature request design and the corresponding quick-changing plate template of processing according to product obtain quick-changing plate;

Step 2: on the upper bolster of mould above the punch, mill out square groove, with the installation dimension and the location matches of quick-changing plate;

Step 3: the punch that use described product all is installed on the mould;

Step 4: before the described product of punching press, install the described quick-changing plate corresponding with described product.

A kind of apparatus for changing punching die quickly; 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.

The invention has the beneficial effects as follows in the mould punching course, do not have the place in hole on quick-changing plate, punch is changed plate pressure and is worked, and plays the stamping-out effect; In the porose place of quick-changing plate, punch contacts stressed with strip, upwards lifts, and by the position, hole of top replacing plate, does not play the stamping-out effect.Like this,, select different quick-changing plate, under the situation of not changing punch, change production fast thereby play according to different products.

Under the situation of not changing punch, change the production of mould fast, avoid loading error, save the replacing time, increase work efficiency.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

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.

Wherein, quick-changing plate [1], 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], soket head cap screw [15].

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

The specific embodiment:

Embodiment 1: a kind of manufacture method of apparatus for changing punching die quickly comprises following steps;

Step 1: make quick-changing plate [1], feature request design and the corresponding quick-changing plate template [1] of processing according to product obtain quick-changing plate [1];

Step 2: on the upper bolster [2] of mould above the punch, mill out square groove;

Step 3: the convex mould pad [3] of the punch that use described product, 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] all is installed on the mould;

Step 4: before the described product of punching press, install the described quick-changing plate [1] corresponding with described product.

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].

Embodiment 2: a kind of manufacture method of apparatus for changing punching die quickly comprises following steps;

Step 1: make quick-changing plate [1 '], feature request design and the corresponding quick-changing plate template [1 '] of processing according to product obtain quick-changing plate [1 '];

Step 2: on the described mould of embodiment 1, back out soket head cap screw [15], take the quick-changing plate [1] of old product, change the quick-changing plate [1 '] of new product, all punch are not changed; As shown in Figure 2;

Step 3: punching press new product.

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 3: 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.
