Abstract

The utility model provides a split type mould for cold heading forming of a gear shaft, aiming at overcoming the defects that a cavity of a cold heading mould is hard to machine, and a die set needs to be changed for the shaft parts with different diameters in the prior art. The split type mould comprises a punching mould and a main mould, wherein the main mould comprises a mould cover and a main mould core mould arranged in the mould cover, the main mould cavity is arranged in the main mould core mould, the main mould core mould consists of an upper core mould, a shaft rod core mould, a spline core mould, a shaft head core mould and an adjusting core mould, and the upper core mould, the shaft rod core mould, the spline core mould, the shaft head core mould and the adjusting core mould are fixedly connected with one another into a whole by the mould cover. After the mould with the structure provided by the utility model is used, the core mould is set to be the split type, and the demoulding of the main mould cavity on each section of the core moulds correspond to each part of the machined gear shaft, so that the machining difficulty of the core mould be reduced, and the sections of core moulds can be assembled according to requirements, so that the quantity of the moulds can be reduced.

Description

The split type mould that the gear shaft cold-heading molding is used
Technical field
The utility model relates to the used split type mould of a kind of gear shaft cold-heading molding.
Background technology
Existing mould comprises punch die and main mould, and main mould comprises die sleeve and core, and core is arranged in the die sleeve.Adopt the mould of this kind structure, when the workpiece of upset system was long-axle workpieces such as gear shaft, the core die cavity was difficult for processing, and need be replaced with mold for the shaft-like workpiece of same diameter different length, made number of molds many, and was difficult for processing.
The utility model content
The purpose of this utility model is, the deficiency that is difficult for processing, need being replaced with mold at prior art cold-heading mold cavity to the axial workpiece of different-diameter, when the axial workpiece of a kind of easy processing and processing same diameter is provided, can not change the used split type mould of gear shaft cold-heading molding of a whole set of mould.
The purpose of this utility model is achieved through the following technical solutions:
The split type mould that a kind of gear shaft cold-heading molding is used, comprise punch die and main mould, described main mould comprises die sleeve and is arranged on the interior main core rod mould of described die sleeve, described master cast chamber is arranged in the main core rod mould, described main core rod mould is made up of last core, axostylus axostyle core, spline core, spindle nose core and adjustment core, fixedlys connected described core, axostylus axostyle core, spline core, spindle nose core and the adjustment core gone up in aggregates by described die sleeve;
The material of described axostylus axostyle core, spline core and spindle nose core is wolfram steel, is provided with the titanizing layer at described axostylus axostyle core, spline core, the pairing master cast of spindle nose core in the chamber.
Adopt the utility model structure mould, because core is arranged to split type, and the exoneration that is positioned at the master cast chamber on each section core is corresponding with each position of the gear shaft of being processed, so not only can reduce the difficulty of processing of core, and can make up each section core according to needs, reduce the quantity of mould.

The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples:
As shown in Figure 1, the split type mould that gear shaft cold-heading molding of the present utility model is used comprises punch die 410 and main mould 440.Be provided with the punch die die cavity 411 that the gear position with gear shaft is complementary in the punch die.Main mould 440 comprises die sleeve 443 and the main core rod mould 430 that is arranged in the die sleeve 443, and master cast chamber 444 is arranged in the main core rod mould 430.
Main core rod mould 430 is provided with according to the concrete structure segmentation of gear shaft.Main core rod mould as present embodiment mainly comprises core 431, axostylus axostyle core 432, spline core 433, spindle nose core 434 and adjusts core 435.Wherein the spline die cavity 423 in master cast chamber 444 is arranged on the spline core 433, and last core 431 is arranged on the top of main core rod mould 430, adjusts the bottom that core 435 is arranged on main core rod mould 430, is used for adjusting the length of whole core.The last core 431 that die sleeve 443 is provided with above-mentioned segmentation, axostylus axostyle core 432, spline core 432, adjustment core 435 and spindle nose core 434 are fixedly connected in aggregates.
Segmentation is provided with main core rod mould 430, has to carry out the core combination according to the length of axostylus axostyle, gear, spline axle head, saves the advantage of the total number of mould.
Preferably the material of axostylus axostyle core, spline core and spindle nose core is wolfram steel, in the chamber titanizing layer is set at described axostylus axostyle core, spline core, the pairing master cast of spindle nose core, can improve the life-span of a whole set of mould like this, improves the machining accuracy of gear shaft.
