Abstract

The invention discloses an auxiliary stripping mechanism in a continuous die, which comprises a swing rod, a stripping rod and a limiting column. The upper end of the swing rod is vertically arranged in an upper template of the progressive die through a rotating shaft; the swing rod can freely swing in the upper template in an angle manner; the swing rod is inserted into the lower template; the upper part of the swing rod is in contact fit with a swing rod return spring fixedly installed in the upper template; a protrusion with a straight edge bevel angle transversely extends out of the lower end of the swing rod to form a right-angle hook with the swing rod; the tail end of the stripping rod is arranged in the lower template of the progressive die through a rotating shaft, so that the stripping rod is transversely arranged in the lower template; the swing rod is matched with the stripping rod. The continuous die has a simple structure, but is reasonable in design, overcomes the defects of a stripping mechanism in the traditional continuous die, and enables the continuous die to be continuously produced efficiently and safely.

Description

Auxiliary material removing mechanism in continuous mould

Technical field

The present invention relates to a kind of mould, specifically a kind of mechanism with the de-material of the auxiliary progressive die.

Background technology

The progressive die, refers to forcing press in a punching stroke, adopts banded punching press raw material, on a secondary mould, with several different stations, complete the cold stamping punch die of multi-step forming processes simultaneously, the every punching press of mould completes once, and material strip fixed-distance moving once, completes to product.For guaranteeing the continuous processing of the progressive die, the progressive die, after production is completed, need to take off material and send.

The material-removing structure that the existing progressive die is used is comparatively simple, as shown in Figure 1, the existing progressive die is used at a de-material mouthful place and uses a liftable floating block 9 by part 8 jack-up, and the part 10 of sending to after use is released, and realizes de-material, there is certain deficiency in this kind of de-material mode, be particularly for and guarantee that angles of product must increase the buoyance lift height of floating block 9, whole material strip buoyance lift height increases, and significantly increases cost.Meanwhile, after the part 10 sent to promote before during part 8, because contact produces, collide, can produce contact and print.In addition, after, the part 10 sent to is gone to sometimes and is treated that de-material part 8 tops cause to clash into and treat de-material part 8 and make to treat that de-material part 8 comes off have burst-mode risk.

In sum, the material-removing structure poor stability in traditional progressive die, can not meet modernization fast, the needs of High-efficient Production, there is certain potential safety hazard simultaneously, industry is needed auxiliary material removing mechanism in a kind of novel progressive die badly.

Summary of the invention

The object of the invention is to overcome material removing mechanism in traditional progressive die existing not in, a kind of auxiliary material removing mechanism in the continuous mould that efficient, safety, de-material efficiency are high that uses is provided.

For achieving the above object, the technical solution adopted in the present invention is:

In a kind of continuous mould, auxiliary material removing mechanism, includes fork, material discharging rod, limited post.

Described fork upper end is vertically mounted on by rotating shaft in the cope match-plate pattern of the progressive die;

Described fork can be angle and freely swing in cope match-plate pattern;

Described fork inserts in lower bolster;

The fork back-moving spring that described fork top and one is packed in cope match-plate pattern contacts cooperation;

The lower end of described fork crosses out a projection with straight flange oblique angle and fork forms a right angle hook;

The tail end of described material discharging rod is arranged in the lower bolster of the progressive die by a rotating shaft, and material discharging rod is horizontally placed in lower bolster;

The described material discharging rod other end can upwards freely rotate along rotating shaft;

The material discharging rod back-moving spring that the lower surface of described material discharging rod and is packed in lower bolster contacts cooperation;

Described material discharging rod is provided with a curved stopper slot;

The limited post that described stopper slot and is arranged in lower bolster coordinates;

Described fork coordinates with described material discharging rod.

When the present invention works, fork is descending with upper bolster at upper bolster, the projection of fork lower end utilizes its right angle hypotenuse and material discharging rod one end in contact will push material discharging rod, de-material in the effect of downforce along rotating under the rotating shaft of its one end, now material discharging rod back-moving spring compressed shape is curved, fork is subject to transverse pressure simultaneously, making fork obtain a spring is squeezed, when fork continues when descending, material discharging rod resets under the effect of back-moving spring, carry out in the corner of right angle hook, then fork is under the drive of upper bolster, up, material discharging rod is hung on fork up with it, material discharging rod promotes the de-material of part, after material discharging rod turns an angle, separation with fork, by self gravitation, drive its reset, and limited post can prevent that it is when high-speed cruising, can be because of the excessive problem that cannot reset of rotational angle.

Though structure of the present invention is comparatively simple, it is reasonable in design, has solved the existing deficiency of material removing mechanism in traditional progressive die, makes the continuous production that the progressive die can be efficient, safe.

The specific embodiment

For convenience of the present invention is understood, the present invention existing in conjunction with Fig. 2 for an embodiment, the present invention is further explained.

Embodiment:

As shown in Figure 2, the present invention includes fork 1, material discharging rod 2, limited post 3, described fork 1 upper end is vertically mounted on by rotating shaft in the cope match-plate pattern 11 of the progressive die; Described fork 1 can be angle and freely swing in cope match-plate pattern 11; Described fork 11 inserts in lower bolster 12; Described fork 1 top contacts cooperation with a fork back-moving spring 6 being packed in cope match-plate pattern 11; The lower end of described fork 1 crosses out a projection 5 with straight flange oblique angle and forms a right angle hook with fork 1; The tail end of described material discharging rod 2 is arranged in the lower bolster 12 of the progressive die by a rotating shaft, and material discharging rod 2 is horizontally placed in lower bolster 12; Described material discharging rod 2 other ends can upwards freely rotate along rotating shaft; The material discharging rod back-moving spring 7 that the lower surface of described material discharging rod 2 and is packed in lower bolster 12 contacts cooperation; Described material discharging rod 2 is provided with a curved stopper slot 4; The limited post 3 that described stopper slot 4 and is arranged in lower bolster 12 coordinates; Described fork 1 coordinates with described material discharging rod 2.
