Description

Tensile mould of conveniently unloading

Technical Field

The utility model relates to a drawing die technical field especially relates to a drawing die of conveniently unloading.

Background

The drawing die is widely used in the field of modern product manufacturing, generally comprises a male die and a female die which are matched up and down, during processing, a material plate is placed between the male die and the female die, and the material plate is punched and drawn into a target shape after the male die and the female die are closed. The biggest problem of the stretching die lies in unloading, the condition that a workpiece is clamped on a male die or embedded in a female die often appears after the die is opened, and reasonable unloading means is needed to help unloading at the moment.

The existing mould unloading structure mainly comprises a rigid unloading structure and an elastic unloading structure. The unloading plate or the unloading rod of the rigid unloading mode is in rigid contact with the workpiece, for example, the unloading plate or the unloading rod acts on the bottom of the workpiece to eject the workpiece, and although the unloading mode is reliable, the surface of the workpiece is easy to deform, so that the quality of a finished product is influenced. The elastic unloading mode adopts an elastic element to push the unloading plate to be in flexible contact with a workpiece, the deformation problem can be effectively solved, the unloading force is small, the elastic element is easy to lose efficacy, the unloading is unreliable, and the floating structure can possibly influence the processing precision.

fig. 2 is a schematic diagram of die assembly of the stretching die facilitating discharging provided by the embodiment of the present invention.

Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

Please refer to fig. 1 and 2, the embodiment provides a stretching mold facilitating discharging, which includes an upper mold base 1 and a lower mold base 2, a male mold fixing plate 3 is disposed on the upper mold base 1, a male mold 4 is disposed on the male mold fixing plate 3, a female mold fixing plate 5 is disposed on the lower mold base 2, a female mold 6 is disposed on the female mold fixing plate 5, a guide pillar 7 is disposed on the male mold fixing plate 3, a guide sleeve 8 matched with the guide pillar 7 is disposed on the female mold fixing plate 5, a through hole 9 is disposed on the lower mold base 2 corresponding to the guide pillar 7, a lower support plate 10 is disposed below the lower mold base 2, and the lower support plate 10 is supported and connected to the lower mold.

Wherein, a first stripper plate 12 and a second stripper plate 13 which are arranged up and down are arranged between the punch 4 and the die 6. The two ends of the first discharging plate 12 are fixedly connected to the female die fixing plate 5 through supporting columns 14 respectively, the two ends of the second discharging plate 13 penetrate through the guide pillars 7 respectively, and springs 15 are sleeved on the guide pillars 7 and between the second discharging plate 13 and the female die fixing plate 5.

The second stripper plate 13 is provided with a material clamp 16, and the material clamp 16 fixedly abuts the edge of the workpiece 17 against the lower surface of the second stripper plate 13.

The male die 4 passes through the first discharging plate 12 and the second discharging plate 13 and then is matched with the female die 6, and male die yielding holes are formed in the first discharging plate 12 and the second discharging plate 13. In particular, when the male die 4 and the female die 6 are closed, the punch retainer 3 is retained by the upper surface of the first stripper plate 12.

The working process is as follows:

1) inserting a starting material plate of a workpiece 17 into a material plate clamp 16 of the second discharging plate 13 to realize fixation;

2) the male die 4 is pressed down, sequentially passes through the first discharging plate 12 and the second discharging plate 13, and after contacting a workpiece 17, the second discharging plate 13 and the workpiece 17 on the second discharging plate are driven to move downwards to be matched with the female die 6, so that stretching processing is realized;

3) after the stretching is finished, the male die 4 is reset to move upwards, the second discharging plate 13 drives the workpiece 17 to move upwards under the action of the elasticity of the spring 15 and the clamping of the male die 4, and therefore the workpiece 17 is separated from the female die 6;

4) the male die 4 and the second stripper plate 13 continuously move upwards, and the upper surface of the second stripper plate 13 is limited by the first stripper plate 12, so that the workpiece 17 is separated from the male die 4;

5) the workpiece 17 is removed from the second stripper plate 13.

The position of the second stripper plate 13 to be urged against the workpiece 17 is an edge portion, and the edge portion generally needs to be reworked, so that there is no fear of damaging the drawing surface. In addition, the first stripper plate 12 acts on the second stripper plate 13, not directly on the workpiece 17, without damaging the workpiece 17, thus ensuring the quality of the drawn product.

To sum up, above-mentioned tensile mould of conveniently unloading is provided with two stripper, and first stripper adopts the rigidity mode of unloading, and the second stripper adopts the elasticity mode of unloading, and tensile completion back, the terrace die resets the in-process and deviates from the work piece from the die through the second stripper, deviates from the work piece from the terrace die through first stripper to the second stripper is spacing to light to unload on can following the second stripper, do not influence tensile technology, do not harm the work piece surface, machining efficiency is high.

The above embodiments have been merely illustrative of the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and does not depart from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
