Description

A kind of cold upsetting die of car

Technical field

The utility model belongs to mould applications, and in particular to a kind of cold upsetting die of car is suitable for both ends size and is greater than intermediate ruler Very little connector product.

Background technique

Current existing some connectors have the stepped construction of segmentation, and the diameter of every section of product is not identical.It is this Both ends size is greater than the connector product of intermediate sizes, and original production technology is after cold heading blank（As shown in Figure 1）, then pass through CNC machining is crossed, last turning goes out intermediate groove structure（As shown in Figure 2）.But turning can not only greatly increase product Production cost, and the utilization rate of material is relatively low, and producing a product about will cause the waste of 30 ~ 50% materials, add Turning speed is slower（10 ~ 20/minute）, long processing time, therefore production capacity is very low.

Utility model content

In view of the above-mentioned problems of the prior art, the utility model has been intended to provide a kind of cold upsetting die of car, produced with improving The production efficiency and stock utilization of product.

To realize above-mentioned technical purpose and the technique effect, the utility model is achieved through the following technical solutions：

A kind of cold upsetting die of car is rushed including what a fixed main mould and one can move up and down below the main mould Mould, the inside of the punch die offer a thimble slot, and the thimble slot runs through the upper and lower ends of the punch die, the thimble slot Top for placing processed product, the lower part of the thimble slot is provided with thimble moving up and down, the main mould and institute State the briquetting being provided between punch die for preventing the processed product displacement.

Further, the briquetting is square structure.

Further, the briquetting has the function of beat folding.

Further, when the punch die moves up, the lower end face contact of the upper surface of the punch die and the briquetting, And the briquetting inwardly closes up, and pushes down the middle part flange collar of the processed product；When the punch die moves down, the punch die Upper surface separated with the lower end surface of the briquetting, and the briquetting outward separate, the middle part for unclamping the processed product is convex Circle.

Further, the punch die upper surface offers the annular embedding of the middle part flange collar for placing the processed product Slot, the annular caulking groove and the thimble slot are coaxial.

Further, the depth of the annular caulking groove is equal or slightly larger than the thickness of flange collar in the middle part of the processed product.

The working principle of the utility model is as follows：

The lower end that the top of processed product is withstood to main mould first, by the thimble of the lower end insertion punch die of processed product Hole, then briquetting inwardly closes up, and pushes down the upper surface of flange collar in the middle part of processed product, and then main mould remains stationary, and punch die drives Thimble moves upwards, and until the lower surface of thimble and processed product is inconsistent, last punch die is continued up, production to be processed The molding of upper end is completed under the extruding of punch die and main mould in the upper surface of product.

The beneficial effects of the utility model are as follows：

The utility model structure is simple, reliable, can be by the molding technique of upper mold and punch die, to the blank of cold-heading molding Part carries out rapid shaping processing, not only substantially increases production efficiency, per minute processable 40-60 part product, and material benefit It is also increased to 99% with rate, cost is greatly reduced.

The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model Art means, and can be implemented in accordance with the contents of the specification, below on the preferred embodiment of the present invention and the accompanying drawings in detail It describes in detail bright as after.Specific embodiment of the present utility model is shown in detail by following embodiment and its attached drawing.

Specific embodiment

Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in detail.

Referring to shown in Fig. 3-7, a kind of cold upsetting die of car, including a fixed main mould 1 and one can be in the main moulds 1 The punch die 2 that lower section moves up and down, the inside of the punch die 2 offer a thimble slot 3, and the thimble slot 3 runs through the punch die 2 Upper and lower ends, for placing processed product 4, the lower part of the thimble slot 3 is provided with can be upper and lower for the top of the thimble slot 3 Mobile thimble 5 is provided with the briquetting 6 for preventing the processed product 4 to be displaced between the main mould 1 and the punch die 2.

Further, the briquetting 6 is square structure.

Further, the briquetting 6 has the function of beat folding.

Further, when the punch die 2 moves up, the upper surface of the punch die 2 and the lower end surface of the briquetting 6 are connect Touching, and the briquetting 6 inwardly closes up, and pushes down the middle part flange collar of the processed product 4；When the punch die 2 moves down, institute The upper surface for stating punch die 2 is separated with the lower end surface of the briquetting 6, and the briquetting 6 separates outward, unclamps the processed product 4 middle part flange collar.
