Abstract

The invention relates to a method for processing an eccentric shaft, which comprises the following three steps of: 1, allowing broken materials to enter a mold for molding, namely setting the mold as a cam shape and performing one-time cold heading molding by using the mold; 2, performing rod-reducing and square heading, namely reducing the middle part of the eccentric shaft by using a rod-reducing mold and directly heading the top end of the middle part of the eccentric shaft to form a square shape; and 3, molding by using an integral mold and performing thread rolling, namely processing the tail part of the eccentric shaft at one time by using the integral mold and performing thread rolling. The three steps are continuously and circularly performed on one multi-station integral mold molding machine. The method improves the processing accuracy of products and greatly reduces the labor intensity of workers and production cost by adopting integral mold design and three-step direct cold heading molding.

Description

A kind of processing method of eccentric shaft
Technical field: the present invention relates to a kind of processing method of automobile-used eccentric shaft, particularly relate to a kind of processing method that is used for the eccentric shaft that uses on the brake on motorcycle, the electric bicycle.
Background technology: the Vehicular series eccentric shaft of being produced on the present market, mainly formed the head of eccentric shaft, the middle part of eccentric shaft, the afterbody of eccentric shaft by three parts, adding man-hour, to adopt different processing technologys according to the shape of product, usually when the head of processing eccentric shaft, adopt following processing technology, raw material with production usefulness strike out blank shape through Cold header earlier, cut edge through punch press, form the cam-like of eccentric shaft head; When the middle part of processing eccentric shaft, owing to be a shape structure, reach required outside diameter, need to squeeze and rein in, with cut edge good material through pressing equipment squeeze rein in after, reach designed requirement, and also need be designed to the square structure on the top at eccentric shaft middle part, so, also will strike out the square shape on its top at eccentric shaft middle part after crowded reining in; Last to be processed be the afterbody of eccentric shaft, need through lathe grinding process arrive certain designing requirement after, and stay surplus thread rolling moulding.Duo processing technology like this should guarantee the crudy of per pass operation, and the expense of taking a lot of work again simultaneously material also will set out the processing mold of multitrace equipment, has increased the processing cost of production, and product quality still can not get the assurance of essence.
Summary of the invention: purpose of the present invention, a kind of new processing method will be provided exactly, can thoroughly solve above product and add existing defective in man-hour, the object of the present invention is achieved like this, a kind of processing method of eccentric shaft is made up of three road stations, 1. the moulding of fracture progressive die, mould is arranged to cam-like, adopts the once cold pier moulding of mould; 2. the bar pier side of contracting the bar mould that the contracts bar that contracts is adopted at the eccentric shaft middle part, and the direct pier in top in the middle goes out square; 3. whole mould is adopted in mould preparation moulding thread rolling, the afterbody of disposable processing eccentric shaft, and thread rolling; Three process is periodic duty continuously on a multistation mould preparation make-up machine.The invention has the beneficial effects as follows that adopt whole mold design, the direct cold pier moulding of three road stations has reduced unnecessary allowance, has improved the machining accuracy of product, has reduced working strength of workers and production cost significantly.

Fig. 2 is a left view of the present invention

The specific embodiment: the processing method of a kind of eccentric shaft of the present invention, formed by three road stations, 1. the moulding of fracture progressive die is arranged to cam-like with mould, adopts the once cold pier moulding of mould; 2. the bar pier side of contracting the bar mould that the contracts bar that contracts is adopted at the eccentric shaft middle part, and the direct pier in top in the middle goes out square; 3. whole mould is adopted in mould preparation moulding thread rolling, the afterbody of disposable processing eccentric shaft, and thread rolling; Three process is to finish product on a multistation mould preparation make-up machine.During concrete enforcement, the moulding of fracture progressive die is exactly according to shape of product, calculates the diameter and the length of each eccentric shaft material therefor, at the mould preparation make-up machine fracture length is set then, fracture, cold pier, the cam-like eccentric wheel of formation eccentric shaft head; The bar pier side of contracting, the eccentric shaft that will form the cam-like of eccentric shaft head on multistation mould preparation make-up machine is sent to second operation work, contract bar to desired bar footpath through the bar mould that contracts, form axle, and directly becoming square at an end top pier of axle, such processing method can guarantee to contract eccentric shaft behind the bar with after its top pier becomes square, can not produce any deviation, can not produce allowance yet, thereby guarantee the precision of required converted products; Mould preparation moulding thread rolling is sent to three process with the product of finishing second operation work on the mould preparation make-up machine, the afterbody of processing eccentric shaft, will become to meet the required diameter of thread rolling with the cold pier in bar footpath of afterbody this moment exactly, behind the cold pier, and directly thread rolling, be processed into screw thread, produce qualified product.Three road stations can circulate continuously carries out work, whenever finishes the production of an eccentric shaft product, and three road stations will move once circularly, thereby has improved the efficient of producing significantly.
