Abstract

The utility model discloses a die convenient for bending and stripping. The die comprises an upper die plate and a lower die plate. A stripping insert unit is installed on the upper die plate; swing stripping inserts are installed symmetrically on the two sides of the stripping insert unit and are embedded in the two side of the stripping insert unit; the swing stripping inserts are square in shape; one corner of each swing stripping insert is connected with and matched with the stripping insert unit through a rotating shaft; rotating movement positions for the swing stripping inserts are left in the surface, which is matched with the rotating shaft ends of the swing stripping inserts, of the stripping insert unit; and the upper surfaces of swing stripping inserts are in contact fit with centers inserted in the stripping insert unit. The die is simple in structure. The stroke of the centers is small so that the direct contact between the centers and part products is prevented and the phenomena of center pressing and rigid scraping are prevented.

Description

Be convenient to the mould of the de-material of bending

Technical field

The utility model relates to the de-material of mould, specifically a kind of pressing and bending mould of being convenient to the de-material of bending.

Background technology

In modern industry life, a lot of mechanism elements need to carry out Bending Processing, in Bending Processing, have artificial bending, also have mould bending.Because of mould bending, compare artificial bending and have efficiently, fast, the advantage such as precision is good, become the main processing mode in Bending Processing.

In the processing of present mould bending, general what use is that thimble is treated processing parts product and beared down on one, and then pushes, and realizes bending distortion.When de-material, thimble rollback, realizes the de-material of product simultaneously.

Adopt directly the bear down on one Bending Mould of product of thimble, although can realize Bending Processing and the de-material of product, but its exist the large and thimble of the movable stroke of thimble because of with the reason such as product contact area is less, have impression and when de-material, the generation of rigidity scraper situation, this kind of mold mechanism is comparatively complicated simultaneously, is unfavorable for debugging maintenance.

Utility model content

It is a kind of simple in structure that the purpose of this utility model is to provide, and de-material is effective, and can not leave at product surface the mould of being convenient to the de-material of bending of impression.

For achieving the above object, the technical scheme that the utility model adopts is: a kind of mould of being convenient to the de-material of bending, includes cope match-plate pattern, lower bolster.

On cope match-plate pattern, be provided with to wave to take off and expect into son;

Describedly de-ly expect to be provided with to wave into sub-bilateral symmetry de-to expect into son;

Described waving de-expects to be embedded in and de-ly to expect into sub-both sides into son;

Described waving de-expects to be square into son, and one angle expects to coordinate into sub-connection with taking off by rotating shaft;

Describedly de-ly expect that son is upper and de-ly expect into sub rotation activity bit with waving to be reserved with on de-mating surface of expecting sub-rotating shaft end to wave;

Described waving de-expects that sub-upper surface expects that the thimble in son contacts cooperation with inserting to take off.

During the utility model work, by taking off, expect to coordinate with die into son, complete Bending Processing, after machining, cope match-plate pattern is up, and drive punch and the product that machine depart from, and now waves to take off and expects on the top of thimble, to depress rotation into son, facilitates discharging.

The utility model is simple in structure, and thimble stroke is little simultaneously, and has avoided thimble to contact with the direct of part product, can prevent the generation of the situations such as thimble impression, rigidity scraper.

The specific embodiment

For convenience of the utility model is done, further understand, existing in conjunction with Fig. 1, Fig. 2 for an embodiment, the utility model is further illustrated.

Embodiment:

In the utility model, include cope match-plate pattern 1, lower bolster 2;

On cope match-plate pattern 1, be provided with to wave to take off and expect into son 3;

Describedly de-ly expect to be provided with to wave into sub 3 bilateral symmetry de-to expect into son 4;

Described waving de-expects to be embedded in and de-ly to expect into sub 3 both sides into son 4;

Described waving de-expects to be square into son 4, and expect into son 3 connection cooperations with de-by rotating shaft at one angle;

Describedly de-ly expect on son 3 to be reserved with and to wave de-rotation activity bit of expecting into son 4 with waving on de-mating surface of expecting sub 4 rotating shaft ends;

Described waving de-expects that sub 4 upper surfaces de-ly expect that the thimble 5 in sub 3 contacts cooperation with inserting.

Claims

1. a mould of being convenient to the de-material of bending, includes cope match-plate pattern, lower bolster, it is characterized in that: on cope match-plate pattern, be provided with to wave to take off and expect into son; Describedly de-ly expect to be provided with to wave into sub-bilateral symmetry de-to expect into son; Described waving de-expects to be embedded in and de-ly to expect into sub-both sides into son; Described waving de-expects to be square into son, and one angle expects to coordinate into sub-connection with taking off by rotating shaft; Describedly de-ly expect that son is upper and de-ly expect into sub rotation activity bit with waving to be reserved with on de-mating surface of expecting sub-rotating shaft end to wave.

2. the mould of being convenient to as described in claim 1 the de-material of bending, is characterized in that: described in wave and de-ly expect that sub-upper surface expects that the thimble in son contacts cooperation with inserting to take off.
