Abstract

The utility model discloses an angle iron perforating die, and belongs to cold blanking dies. The angle iron perforating die comprises a die handle, an upper die seat, a perforating die fixing plate and a lower die seat, a male die is arranged on the lower surface of the perforating die fixing plate, a female die matched with the male die is arranged on the upper surface of the lower die seat, the front middle end of the upper surface of the female die extends to the bottom end to form a step type groove, and cutting edges in a right angle shape and in a circular shape are arranged at the front end, corresponding to the front end of the bottom of the male die, of the step type groove. Through the mode, angle iron is fixed through the step type groove, a round hole and two chamfers of the angle iron can be machined in the die at one time through the cutting edges at the bottom of the male die, clamping is not needed in the hole punching process, and machining cost is greatly lowered. Meanwhile, it is guaranteed that the form tolerance and the position tolerance of the round hole meet the later assembling need, large deviation is effectively prevented from being caused by drilling machine machining, and production efficiency and the yield of parts are improved.

Description

A kind of angle steel eyelet work mould
Technical field
The utility model relates to cold punching die field, be particularly related to specially and improve the quality of staircase and girder part and a kind of angle steel eyelet work 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.
The dimensional accuracy of staircase and girder part is larger to the integral installation quality influence of truss, as it is a lot of not enough to adopt traditional machined (saw, milling, brill) blanking to exist, particularly process circular hole and two place's chamferings on angle steel, the bottom outlet of thread mill drilling is as adopted drilling machine processing, line and clamping all can produce error, the form tolerance in hole and the deviation of position of related features are larger, affect later stage assembling, have greatly affected production efficiency.
Therefore, design and can realize the disposable location that completes of channel-section steel bar hole for above-mentioned situation, reduce mismachining tolerance, guaranteed that the form tolerance in hole and position of related features meet a kind of angle steel eyelet work mould of later stage assembling, 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 eyelet work mould, can make the circular hole of angle steel and two place's chamfering is disposable machines, and has guaranteed that the form tolerance in hole and position of related features meet later stage assembling, have improved the qualification rate of part greatly.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of angle steel eyelet work 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 die shoe upper surface is provided with the die coordinating with punch, the middle front end of described die upper surface extends to bottom and offers notch cuttype groove, and the bottom front of the corresponding punch of front end of described notch cuttype groove is provided with rectangular triangle and circular cutting edge.
The beneficial effects of the utility model are: the utility model is by the fixing angle steel of notch cuttype groove, circular hole and two place's chamferings that can realize angle steel by the cutting edge of punch bottom once complete processing in mould, and without clamping, greatly reduce processing cost when punching; Meanwhile, guarantee that the form tolerance of circular hole and position of related features meet later stage matching requirements, effectively avoided drilling machine processing to bring relatively large deviation, 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.
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 die shoe 8 upper surfaces are provided with the die 7 coordinating with punch 6, the middle front end of described die 7 upper surfaces extends to bottom and offers notch cuttype groove, and the bottom front of the corresponding punch 7 of front end of described notch cuttype groove is provided with rectangular triangle and circular cutting edge.
In the present embodiment, this perforating die 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, punch 6, guide plate 5 and back-moving springs 9; Counterdie is made up of parts such as die 7 and die shoes 8.
The installation of perforating die: first this perforating die 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; Die shoe 8 is fixed on platform with pressing plate; Angle steel 10 is fixed in the stepped groove of die 7.
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 is by the fixing angle steel 10 of notch cuttype groove, and circular hole and two place's chamferings that can realize angle steel by the cutting edge of punch 6 bottoms once complete processing in mould, and when punching without clamping, greatly reduce processing cost; Meanwhile, guarantee that the form tolerance of circular hole and position of related features meet later stage matching requirements, effectively avoided drilling machine processing to bring relatively large deviation, 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.
