Description

A kind of special male model block of ball stud trimming

Technical field

The utility model belongs to hardware spare and accessory parts technical field, is exactly specifically a kind of special male model gear of ball stud trimming Block.

Background technology

Usually using to various hardwares are as processing and install in machinery industry, such as ball stud is exactly a kind of common Hardware.Ball stud is widely adopted in independent suspension system, and control arm or distance rod are usually through the ball positioned at end Head pin is connected with other parts.The major function of ball stud is to realize wheel bob and divertical motion.Ball pin face is added Work required precision is higher, many steel alloys good using quenching degree, and the ball pin surface coordinated is done with metal ball to be quenched using high frequency The Surface hardening treatments such as fire, to improve wearability.It is now many to be coordinated using ball pin with nonmetallic ball seat, therefore ball pin need to only be adopted Take modifier treatment.In the manufacturing process of ball stud, the mode for carrying out being machined refine to cold-heading product is main flow, to material Heat Treatment Control be key factor, in addition for the product of the such taper connection type of ball stud, its dimensional accuracy be fatigue The key factor of limit stability in terms of cold upsetting die of car, it is necessary to take measures.

But, such ball pin structure is in cold-heading molding, and the hexagon step between bulb and screw rod needs to be cutting into Type, trimming terminates moment, and trimming waste material is because workpiece is separated inside pneumatic rear pass-out high speed jacking male model with workpiece, and is cut The workpiece that side is completed is then to knock the male model block of built-in bevelling at a high speed and turn to and fall into feed opening below male model.And it is general The mould steel capital it is also firmly more many than workpiece material, so common male model block easily cause workpiece be bruised and output not Non-defective unit, so that the once production qualification rate of cold extrusion process can not always be lifted.

Utility model content

The purpose of this utility model is ejected aiming at trimming workpiece in existing cold extrusion shaped ball stud manufacturing process The technological deficiency that Shi Rongyi damages can more stablize pneumatic after the undertaking trimming of flexibility there is provided a kind of special male model block The cold extrusion half-finished parts of pass-out ejection at a high speed, effectively prevent trimming workpiece when high speed is ejected directly and hard gold afterwards Category collision, it is to avoid produce part and seriously damaged, increase the qualification rate of cold-heading semi-finished product, reduce the waste of raw material, save Production cost.

Technical scheme

In order to realize above-mentioned technical purpose, a kind of special male model block of ball stud trimming of the utility model design, its spy Levy and be：It includes male model stop block body, and it is in C-channel mouthful, C-shaped pocket bottom that the left-hand end of the male model stop block body, which is provided with, Chock is embedded with, the C-channel mouthful bottom surface is oblique angle face, and the male model stop block body right-hand end makes chock and outer provided with path through hole Boundary is connected, and the semicircle shallow slot through whole male model stop block body is axially arranged with the male model stop block body periphery.

Further, the C-channel mouthful bottom surface is flushed with chock.

Further, the chock is elastomer.

Beneficial effect

The special male model block of a kind of ball stud trimming that the utility model is provided, its distinctive elastomer or low-intensity gold Abaculus can more be stablized by the cold extrusion half-finished parts of pneumatic rear pass-out high speed ejection after flexible undertaking trimming in the middle of category, Effectively prevent that trimming workpiece from directly colliding when high speed is ejected with hard metal, it is to avoid produce part and seriously damaged.

Brief description of the drawings

Accompanying drawing 1 is the front view of the utility model embodiment.

Accompanying drawing 2 is the structural representation of the utility model embodiment.

Embodiment

With reference to the accompanying drawings and examples, the utility model is described further.

Embodiment

As shown in figure 1 and 2, the special male model block of a kind of ball stud trimming, it includes male model stop block body 1, the public affairs It is C-channel mouthful 101 that the left-hand end of mould stop block body 1, which is provided with, and 101 bottoms of C-channel mouthful are embedded with chock 102, the C-channel mouthful 101 bottom surfaces are oblique angle face 106, and the right-hand end of male model stop block body 1 makes chock 102 be in communication with the outside provided with path through hole 104, The semicircle shallow slot 105 through whole male model stop block body 1 is axially arranged with the periphery of male model stop block body 1.

101 bottom surfaces of the C-channel mouthful are flushed with chock 102.

The chock 102 is elastomer.

The special male model block of a kind of ball stud trimming that the utility model is provided, its distinctive elastomer or low-intensity gold Abaculus can more be stablized by the cold extrusion half-finished parts of pneumatic rear pass-out high speed ejection after flexible undertaking trimming in the middle of category, Effectively prevent that trimming workpiece from directly colliding when high speed is ejected with hard metal, it is to avoid produce part and seriously damaged.

Structure, ratio, size depicted in embodiment institute accompanying drawings etc., only to coordinate in disclosed in specification Hold, so that those skilled in the art is understood with reading, be not limited to the enforceable qualifications of the utility model, therefore not Has technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influenceing this practicality new Under effect that type can be generated and the purpose that can reach, it all should still fall and obtain and can contain in the technology contents disclosed in the utility model In the range of lid.Meanwhile, cited such as " on ", " under ", "left", "right", the term at " middle part " in this specification are also only It is easy to understanding for narration, and is not used to limit the enforceable scope of the utility model, its relativeness is altered or modified, in nothing Under essence change technology contents, when being also considered as the enforceable category of the utility model.
