Abstract

The utility model discloses a bending and stripping mechanism. The bending and stripping mechanism comprises an upper part and a lower part which are arranged in an upper die and a lower die respectively. The upper part comprises a stripping plate; the lower part comprises a material pressing block used for pressing a workpiece to be bent on the stripping plate, pushing rods for driving the material pressing block to move, and a punch used for bending the workpiece to be bent; an avoidance hole is disposed on the stripping plate, the punch directly faces the avoidance hole, and a stripping part used for pushing the bent and formed workpiece away from the stripping plate is also arranged on the stripping plate. With addition of the downwards-acting stripping part on the stripping plate, the workpiece to be bent is ensured to be timely stripped away from the stripping plate, conventionally required processes such as pre-bending are omitted, the production efficiency is raised, and production safety is simultaneously ensured.

Description

A kind of bending and material removing mechanism
Technical field
The utility model relates to a kind of bending and material removing mechanism.
Background technology
Bending and molding is a kind of common technology in punching production, is that independent Bending punch and bending and molding piece carrys out moulding usually.Although such structure is simple and convenient, for the special bending structure of product requirement, especially product bending 90 degree or negative angles, near bending with taking out tooth, convex closure etc. and being difficult for taking off material, often do not reach client's requirement.At present, what adopt for the similar structure of bending in the common progressive die is all first to pre-fold 45 degree or 60 degree avoid taking out tooth, convex closure etc., then adopt the side slide mechanism that the vertical up-or-down movement of punch press is converted to horizontal movement, and then after bending and molding is completed, the disengaging of having return product against side slide mechanism, this structure is high and processing cost is high for the requirement on machining accuracy of mould, and then causes the rising of production unit cost, and this kind structure mold maintenance difficult.Moreover, in lasting a large amount of production of the progressive die,, in case product produces misdelivery in mould, easily cause blocking of side slide mechanism, and then slotting tool mechanism is left behind,, if mould continues motion, will cause serious injury mould and producers.
Summary of the invention
The purpose of this utility model is to provide a kind of handling safety and high bending and the material removing mechanism of production efficiency.
for achieving the above object, the technical solution adopted in the utility model is: a kind of bending and material removing mechanism, it comprises the upper and lower that is arranged on respectively in upper mould and counterdie, described top comprises stripper plate, described bottom comprises for treating that bending part holds out against the binder block on stripper plate, drive the push rod of binder block motion and the drift that is used for treating the bending part bending, offer on described stripper plate and keep away a hole, described drift is over against a described hole of keeping away, also be provided with on described stripper plate for treating after bending and molding being rushed curved the material section of taking off that pushes away described stripper plate.
Optimize, the end face that described stripper plate is relative with described binder block is lower surface, and the described material section of taking off comprises an end and described stripper plate rotate and be connected take off the material piece, be connected to the spring that takes off between the material other end of piece and stripper plate lower surface and be in compressive state.
Optimize, the end face that described stripper plate is relative with described binder block is lower surface, and the described material section of taking off is the spring leaf that cross section is " V " type, and one of them side of described spring leaf is fixed on the lower surface of described stripper plate.
Optimize, described top also comprises the baffle plate that is fixedly connected with described frame and removably connects with described stripper plate.
Further, described bottom also comprises the lower bolster that is fixedly connected with frame, removably connect with described lower bolster and end face mounted thereto on lower bolster, described drift is arranged on described lower bolster.
Because technique scheme is used, the utility model compared with prior art has following advantages: the utility model is set up the material section of taking off of downward effect on stripper plate, guaranteed to treat that bending part can in time break away from stripper plate, the operations such as pre-folding of original needs have been saved, improve production efficiency, guaranteed simultaneously the safety of producing.

Structural representation when accompanying drawing 3 is curved for until bending part, rushing;
Accompanying drawing 4 is for rushing the structural representation after curved disengaging;
In above accompanying drawing: 1, drift; 2, treat bending part; 3, spring; 4, set screw; 5, take off the material piece; 7, binder block; 8, push rod; 9, top; 10, bottom; 11, stripper plate; 12, keep away a hole; 13, take off material section; 14, baffle plate; 15, lower bolster; 16, lower bolster.
The specific embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
Embodiment one: shown in accompanying drawing 1.
This bending comprises with material removing mechanism top 9 and the bottom 10 that is arranged on respectively in upper mould and counterdie, the material section 13 of taking off in the stripper plate 11 that top 9 comprises baffle plate 14, removably connect with baffle plate 14 lower surfaces, the groove that is arranged on stripper plate 11 lower surfaces, take off material section 13 and comprise that an end and stripper plate 11 the taking off of being connected that rotate expect piece 5, be connected to the spring 3 that takes off between the other end of expecting piece 5 and stripper plate 11 groove end faces and be in compressive state.Bottom 10 comprises lower bolster 15, removably connect with lower bolster 15 and end face mounted thereto on lower bolster 16, be used for treating that bending part 2 holds out against at the binder block 7 on stripper plate 11, is used for driving the push rod 8 of binder block 7 motions and is arranged on lower bolster 16 and is used for treating the drift 1 of bending part bending, treat that bending part 2 is connected on strip, and strip accurately is positioned on mould, offer on stripper plate 11 and keep away a hole 12, drift 1 is over against keeping away a hole 12.
As shown in Fig. 1~4, this bending is as follows with the operation principle of material removing mechanism:
Along with the motion of mould, the material piece that takes off fixed thereon moves downward, and can make product moulding on the basis of last station moulding, and take off and expect that piece clockwise rotates, and molds the structure of product requirement together with the drift that is fixed in counterdie; After the mould closure, along with the further motion of punch press, the mould upper and lower mould starts to separate, and takes off the material piece and moves upward, and taking off simultaneously the material piece can rotate counterclockwise around the bending and molding piece under the effect of spring, and then breaks away from and not there will be interference from type product.
Embodiment two
The distinctive points of the present embodiment and embodiment one is: take off in the present embodiment material section 13 and be the spring leaf of " V " type for cross section, one of them side of spring leaf is fixed on the lower surface of stripper plate 11.It is simple in structure than embodiment one, but service life is shorter.
