Abstract
The utility model discloses a side cut pushes away tooth integration mould for push away tooth integrated into one piece to the side cut of auto steering dish blank, it includes that the lower mould treats the processing blank on and carry out the supporting seat that the terminal surface supported the location, mould on this lower mould top is provided with with it move and matched with, and it is right to have set firmly on the mould at this shang wait to process cutter that the blank circumference goes on cutting edge, and right wait to process the blank mesopore and carry out the push -type broach that the spline pushed away the tooth, wherein upward being equipped with with it on the mould, relative motion just is used for treating the pressure disk that the processing blank compressed tightly the location. The utility model discloses a simple structure, operation convenient to use can realize cutting edge on the hydraulic press and push away tooth integration shaping, has simplified traditional processing technology, has reduced the manufacture craft cost, has improved production efficiency.
Description
Technical field
The utility model relates to a kind of trimming tooth pushing integrated mould, be specifically related to a kind of for excising the stub bar of car steering wheel die-casting blank part, overlap cleaning and the trimming tooth pushing integrated mould of spline tooth Slot shaping.
Background technology
Current car steering wheel moulding process is mainly: die casting-trimming-La tooth-polishing-packaging shipping, spline teeth groove needs to adopt separately to draw the mode of tooth to carry out, special broaching machine processing need be adopted, consider from cost savings, by carrying out again after trimming technology drawing tooth technique, processing relative complex, therefore, people are devoted to trimming to draw tooth integrative-structure with drawing tooth technique to combine to form trimming.Such as license notification number CN200960536Y patent name is a kind of automatic gear pulling shaping die for the manufacture of metal zip fastener, it is respectively arranged with upper edge-trimming cutter, the lower edge-trimming cutter shearing and coordinate on upper die and lower die, and shear the upper gear cutter, the lower gear cutter that coordinate, structure is simple, speed of production is fast, can be mass.But car steering wheel trimming draws tooth technique then different, spline teeth groove can not one-step punching put in place, need push broach to be made step-type ladder push broach, thus cause push broach stroke very long, reach 150 ~ 200mm, only rely on mould to realize hold down gag and can not meet its die-cut stroke, these technological difficulties are necessary to solve, could realize on hydraulic press, carry out trimming and tooth pushing integrated molding, car steering wheel moulding process is changed to: die casting-trimming tooth pushing-polishing-packaging shipping.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model aims to provide a kind of trimming tooth pushing integrated mould, its structure is simple, easy for operation, can realize on hydraulic press, carry out trimming and tooth pushing integrated molding, simplify conventional machining process, reduce manufacture craft cost, improve production efficiency.
To achieve these goals, the technical solution of the utility model: a kind of trimming tooth pushing integrated mould, for one-body molded to the trimming tooth pushing of car steering wheel blank, it comprise counterdie and on treat the supporting seat that machining blanks part carries out end face supporting and location, being provided with above this counterdie can move toward one another and the patrix matched with it, this patrix is installed with the cutting knife described blank circumference to be processed being carried out to trimming, and described blank mesopore to be processed is carried out to the push broach of spline tooth pushing, wherein, described patrix is provided with motion in contrast and carries out compressing the platen of locating for treating machining blanks part.
Further, described push broach is step-by-step stepped push broach.
Further, described patrix top is provided with and orders about the first oil cylinder that this patrix makes lifting action.
Further, in described patrix, be installed with the second oil cylinder, this second oil cylinder by push rod and described platen affixed, and this push rod relative sliding is with described blank to be processed relative on described patrix.
Further, in the middle part of described counterdie, technique withdrawing hole is provided with.
During use, starting device run switch, hydraulic press master cylinder i.e. the first oil cylinder orders about patrix and presses down, whole mould starts matched moulds, when master cylinder presses to desired location, be converted at a slow speed, start secondary cylinder i.e. the second hydraulic oil cylinder driving platen simultaneously and press down, after blank to be processed is pushed down, master cylinder continues to run, driving cutting knife, push broach are treated machining blanks part respectively and are carried out trimming, spline tooth pushing, and after tooth pushing trimming completes, master cylinder gos up, during the complete returned work of push broach, secondary cylinder stops, and platen resets, and namely completes whole trimming tooth pushing technique.
The beneficial effects of the utility model: structure is simple, easy for operation, can realize carrying out trimming and tooth pushing integrated molding on hydraulic press, simplify conventional machining process, reduce manufacture craft cost, improve production efficiency.
Accompanying drawing explanation
Using state schematic diagram when Fig. 1 is the utility model die sinking;
Using state schematic diagram when Fig. 2 is the utility model matched moulds.
Detailed description of the invention
The utility model is further described below in conjunction with specific embodiment and accompanying drawing.
A kind of as Fig. 1, trimming tooth pushing integrated mould described in Fig. 2, for one-body molded to the trimming tooth pushing of car steering wheel blank, it comprise counterdie 2 and on treat the supporting seat 22 that machining blanks part 3 carries out end face supporting and location, being provided with above this counterdie 2 can move toward one another and the patrix 1 matched with it, this patrix 1 is installed with the cutting knife 11 described blank 3 circumference to be processed being carried out to trimming, and described blank 3 mesopore to be processed is carried out to the push broach 14 of spline tooth pushing, wherein, described patrix 1 is provided with motion in contrast and carries out compressing the platen 12 of locating for treating machining blanks part 3.
During use, in the process of patrix 1 matched moulds, first by platen 12 treat machining blanks part 3 carry out compression location after, patrix 1 continues matched moulds, by cutting knife 11, push broach 14, trimming, tooth pushing are carried out to this blank 3 to be processed, can realize carrying out trimming and tooth pushing integrated molding simultaneously on hydraulic press, simplify conventional machining process, reduce manufacture craft cost, improve production efficiency.
Preferably, push broach 14 is step-by-step stepped push broach, and the push broach stroke of this push broach 14 can reach 150 ~ 200mm, substitutes traditional broaching tool structure.
