Abstract
The utility model discloses a cold punching die, which comprises a base and a punching head, and is characterized by also comprising ejecting rods, an upper support, a sliding block, a spring and a clamping tool, wherein ejecting rod mounting holes in the same number as the ejecting rods and matched with the ejecting rods are formed on the base; a limiting step is formed on the upper end of the upper support; the upper support is fixed on the base; the base is provided with a clamp; the spring is sleeved on the clamp; the sliding block is placed on the spring; the clamp, spring and sliding block all are positioned in hollow cavities formed by the base and the upper support; the punching head passes through the sliding block and the spring; the punching head is fixedly connected with the clamp; the punching head has an edge part and a positioning pin; and the positioning pin extends out of the sliding block. In the utility model, the bottom part of the punching head has a fixing hole, and the punching head is fixedly connected with the clamp through a pin. The edge part and the positioning pin of the cold punching die are formed into a whole. Compared with the prior art, the cold punching die has the advantages of reasonable design, simple structure, convenience for operation and stable processing quality.
Description
Technical field
The utility model relates to a kind of cold punching die, is mainly used in the axial bore of processing component of rod category.
Background technology
In general the cold punching die of the axial bore of processing component of rod category all adopts traditional structure in the technology now, when having only shape need and do not have the position degree and require, can satisfy fully the endoporus of part to be processed, but it is more and more higher that existing part requires, as then meet difficulty when guaranteeing the concentricity requirement of processed endoporus: because drift all is arranged in the patrix in the traditional moulds, thereby when operation the essential positioning fixture of setting a product to be processed, and this clamp for machining is installed in the patrix by debugging, man-hour product to be processed is installed in the anchor clamps and add, such mould is comparatively complicated in conjunction with the structure of anchor clamps, not only cost of manufacture is higher, and Installation and Debugging complexity, simultaneously because the installation of several procedures of process, repetitive positioning accuracy is relatively poor, often process the product concentricity precision instability that obtains, the quality instability is brought many difficulties to batch process.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and provides a kind of reasonable in design, and is simple in structure, easy to operate, the cold punching die that processing quality is stable.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this cold punching die, comprise base, drift, it is characterized in that also being provided with push rod, upper bracket, slide block, spring and anchor clamps, described base is provided with the push rod installing hole that quantity is identical with push rod and cooperatively interact, described upper bracket top is provided with a limited step, described upper bracket is fixed on the base, on the described base anchor clamps are set, spring housing is on anchor clamps, slide block places on the spring, anchor clamps, spring and slide block all are arranged in base and the formed cavity of upper bracket, described drift passes slide block, spring, drift is fixedlyed connected with anchor clamps, and described drift is provided with blade and alignment pin, and described alignment pin stretches out the last plane of slide block.
The quantity of push rod described in the utility model and push rod installing hole is three.
The bottom of drift described in the utility model has fixing hole, and drift is fixedlyed connected by pin with anchor clamps.
The utility model blade and alignment pin fuse.
The utility model compared with prior art has following positive effect: reasonable in design, simple in structure, easy to operate, processing quality is stable.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Referring to Fig. 1, the utility model embodiment comprises base 1, push rod 2, upper bracket 3, slide block 4, drift 5, spring 6, anchor clamps 7, dip mold 8.Described base 1 is provided with the push rod installing hole 11 that quantity and push rod 2 are identical and cooperatively interact, a limited step 31 is arranged at the top of described upper bracket 3, described upper bracket 3 is fixed on the base 1, set gradually anchor clamps 7, spring 6 and slide block 4 from the bottom up in described base 1 and the upper bracket 3 formed spaces (cavity), described drift 5 passes slide block 4 and spring 6 and is fixed in the anchor clamps 7, described drift 5 is provided with blade 51 and alignment pin 52, and described alignment pin 52 stretches out the last plane of slide block 4.
The bottom of drift 5 described in the utility model has fixing hole 53, fixes by pin 9.
The utility model compared with prior art its advantage is:
Reasonable in design, simple in structure, when not need not to process product to be processed 10 is put into specific anchor clamps, the Mold Making cost reduces greatly, as the drift 5 that only need change different size when changing in the different hole, processed cross section gets final product. Operating personnel only need the inner hole sleeve of product to be processed 10 get final product at drift 5 during production, and are easy to operate, workman's technical merit required low, and the precision that can reduce resetting is stablized processing quality.
Allly conceive equivalence or the simple change that described structure, feature and principle are done according to the utility model patent, be included in the protection domain of the utility model patent.
