Abstract
The utility model relates to a punching mould for an inclined plane hole. A wedge is arranged on an upper mould part of the punching mould; a slide block is arranged aside the wedge; an inclined plane is arranged on the slide block; the inclined plane is jointed with a slope of the wedge; a punching head of the punching mould is located at the front end of the slide block; besides, a sliding auxiliary bolt is arranged on the lower part of the slide block; a cavity is arranged at the front end of the sliding auxiliary bolt; and meanwhile, a spring is arranged in the cavity. The punching mould for the inclined plane hole has the advantages of simple process, convenience in processing, easiness in assembling, high processing precision and excellent consistency of products.
Description
Technical field
The utility model relates to the machining mould, and being specially needs the beveled aperture punching die used in a kind of locomotive fittings manufacturing process.
Background technology
In general, in the manufacture field of automotive component, often need to process some special workpieces, just often need to carry out punch operation to the lateral section of workpiece in these workpiece.This punch operation all is to adopt drilling machine to process usually, and adding man-hour need to be with workpiece side to placement.Its weak point is: production efficiency is low, and bit wear consumption need more manual intervention, thereby labor strength is large seriously, simultaneously.
Also there is the staking punch that adopts wedge structure to carry out punching press to realize aforesaid operations, but, adopt this mode to process, processing effect for some regular textures is obvious, but easily make the impulse force skewness of drift for the inclined-plane of some irregular structures, easily produce and slide, not only affect machining accuracy, but also easy mold damage.
The utility model content
The technical problem that the utility model solves is to provide a kind of beveled aperture punching die, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
The beveled aperture punching die is provided with a wedge on its part of the upper die, the wedge side is other to be provided with a slide block, is provided with an inclined plane on the described slide block, fits in the inclined-plane of described inclined plane and wedge, and the drift of punching die then is positioned at slip front; In addition, be provided with the auxiliary bolt that slides in the slide block bottom, and be provided with a cavity at the auxiliary bolt front end that slides, in cavity, be provided with a spring simultaneously.
In the utility model, the described cavity that spring is housed, its top connection sliding block, the bottom then is fixed in the slotted eye on the lower bolster by take-up housing.
Beneficial effect: Mould operation described in the utility model is reliable, and is simple, safety, but the operating efficiency of Effective Raise die punching, and simultaneously, Product Precision is high, and high conformity also can effectively save production cost.
Description of drawings
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to the preferred embodiment of the beveled aperture punching die of Fig. 1, in the present embodiment, the beveled aperture punching die comprises cope match-plate pattern 1 and lower bolster 4, is provided with a wedge 2 in its part of the upper die, and wedge 2 sides are other to be provided with a slide block 5, and drift 6 then is positioned at slide block 5 front ends; In addition, be provided with the auxiliary bolt 3 that slides in slide block 5 bottoms, auxiliary bolt 3 front ends that slide are provided with one with the cavity 7 of spring.
The present embodiment is fixed in workpiece first in the working hole 8 on the lower bolster 4 when work, and punch press moves downward and presses down cope match-plate pattern 1, drives oblique contract 2 and pushes down slide block 5, makes its oblique movement, and goes out side opening.After having rushed, punch press moves upward, and slide block 5 relies on the elastic reset of the spring in the cavity 7.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
