Abstract

The utility model discloses an angle steel opening die, and belongs to the field of cold blanking dies. The angle steel opening die comprises a die handle, an upper die base, a punching die fixing plate and a lower die base. A male die is arranged on the lower surface of the punching die fixing plate and is of a triangular prism shape, a female die matched with the male die is arranged on the upper surface of the lower die base, and through stepped grooves are formed in the upper surface of the female die. In the mode, through the cooperation of the male die with the female die, 90-degree openings of angle steel can be machined in the die at a time, so that machining cost is greatly lowered; meanwhile the problem of accuracy of form and position tolerance is solved, scratches and thermal deformation caused by plasma cutting are effectively avoided, it is guaranteed that the forms and the positions of the 90-degree openings meet the tolerance requirement, production efficiency is improved, and the percent of pass of parts is increased.

Description

A kind of angle steel gap mould

Technical field

The utility model relates to cold punching die field, particularly relate to special in improving the gas cylinder bracket quality of part and a kind of angle steel gap mould of efficiency.

Background technology

Punching press is at room temperature, utilizes the mould being arranged on forcing press to exert pressure to material, makes it produce distortion separation, thereby obtains a kind of pressure processing method of required part.

Diel is technology-intensive product, is one of important symbol of weighing enterprise product manufacture level height, is determining to a great extent the development ability of quality and benifit and the new product of product.

Gas cylinder bracket is produced by the dimensional accuracy of part larger on the total quality impact of gas cylinder bracket, as it is a lot of not enough to adopt traditional machined (saw, milling, brill) blanking to exist, particularly process 90 ° of gap of angle steel, generally cannot in a mold, complete location again, when punching, need clamping, increased processing cost; In addition, process 90 ° of gap as adopted plasma cutting, shape and position all can be subject to the impact of line and thermal deformation, and can produce burr and splash, and cannot meet tolerance, greatly reduce the qualification rate of part.

Therefore, design for above-mentioned situation 90 ° of disposable machining of gap can realizing angle steel, reduce mismachining tolerance, improve a kind of angle steel gap mould of part qualification rate, inventor's problem to be solved just.

Utility model content

The technical problem that the utility model mainly solves is to provide a kind of angle steel gap mould, can realize 90 ° of disposable machining of gap of angle steel, effectively avoids 90 ° of gap to be subject to line and the impact of thermal deformation, has greatly improved the qualification rate of angle steel.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of angle steel gap mould is provided, comprise die shank, upper bolster, punch die fixed head and die shoe, described punch die fixed head lower surface is provided with punch, described punch is triangle column, described die shoe upper surface is provided with the die coordinating with punch, and described die upper surface offers the notch cuttype groove of perforation.

In preferred embodiment of the utility model, described die shoe bottom is provided with installing plate, and described installing plate is strip parallel construction.

The beneficial effects of the utility model are: the utility model, by the cooperation of punch and die, can be realized 90 ° of gap of angle steel and in mould, once complete processing, greatly reduces processing cost; Meanwhile, solved the precision problem of form and position tolerance, line and the influence of thermal deformation of effectively avoiding plasma cutting to bring, guaranteed that shape and the position of 90 ° of gap meets tolerance, improved the qualification rate of production efficiency and part.

Accompanying drawing explanation

Fig. 1 is perspective view of the present utility model;

In accompanying drawing, the mark of each parts is as follows: 1, die shank 2, upper bolster 3, punch die fixed head 4, guide pillar 5, guide plate 6, punch 7, die 8, die shoe 9, back-moving spring 10, angle steel 11, installing plate.

The specific embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.

Refer to Fig. 1, the utility model embodiment comprises: die shank 1, upper bolster 2, punch die fixed head 3 and die shoe 8, described punch die fixed head 3 lower surfaces are provided with punch 6, described punch 6 is triangle column, described die shoe 8 upper surfaces are provided with the die 7 coordinating with punch 6, and described die 7 upper surfaces offer the notch cuttype groove of perforation.

In preferred embodiment of the utility model, described die shoe 8 bottoms are provided with installing plate 11, and described installing plate 11 is strip parallel construction, like this in punching course, installing plate 11 can decompose the impulsive force that die shoe 8 bears, and also makes gap mould overall structure more firm.

In the present embodiment, this gap mould is single operation blanking die of a subband guide pillar.Be made up of upper and lower mould two parts, patrix is made up of parts such as die shank 1, upper bolster 2, punch die fixed head 3, guide pillar 4, guide plate 5, punch 6 and back-moving springs 9; Counterdie is made up of parts such as installing plate 11, die 7 and die shoes 8.

The installation of gap mould: first this gap mould entirety is positioned on the platform of press; By press power knob crawl, regulate the slide block of press downwards again, make slide block exceed 5-10mm than die shank 1; The die shank cover of again die shank 1 being aimed to press ram, moves down press slide, makes die shank 1 embed press slide completely; With the fixing die shank 1 of the screw on slide block; The installing plate 11 of die shoe 8 is fixed on platform with pressing plate, angle steel 10 is placed in the stepped groove of die 7 fixing.

Adjust press work distance: regulate the stroke screw rod of press slide, make slide block in lower limit, at this moment upper and lower mould is fitted completely, but back-moving spring does not stress; By press power knob crawl, make upper and lower mould separately again, and then regulate the stroke screw rod of press slide, make it move down the thickness of a workpiece.

Initial workpiece examination punching: first check whether photoelectric protector (safe grating) works; Check that whether fracture after initial workpiece punching press is jagged and tear; If any, then regulate press slide downwards, so repeatedly, until workpiece fracture is neat; Whether the dimensional tolerance that checks initial workpiece meets drawing requirement, if any deviation, regulates by grid, until the initial workpiece product of producing conforms to quality requirements; Produce in batches.

The utility model, by the cooperation of punch 6 and die 7, can be realized 90 ° of gap of angle steel and in mould, once complete processing, greatly reduces processing cost; Meanwhile, solved the precision problem of form and position tolerance, line and the influence of thermal deformation of effectively avoiding plasma cutting to bring, guaranteed that shape and the position of 90 ° of gap meets tolerance, improved the qualification rate of production efficiency and part.

The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
