Abstract

The invention discloses a belt pulley forging mould which comprises a stress outer sleeve, a cavity module, a bottom plate and a pressing head module, wherein the cavity module comprises an annular cavity; an annular mould groove is formed in an inner wall of the annular cavity; an opening plane of the annular mould groove is 25mm lower than an opening plane of the annular cavity; the pressing head module comprises a forming ring groove; an outer wall of the forming ring groove is in clearance fit with the inner wall of the annular cavity; and an opening plane of the forming ring groove is bonded with the opening plane of the annular mould groove. A belt pulley manufactured by the mould has no flashes, and the mould can be recycled, and is long in service life and low in cost.

Description

The belt pulley forging mold
Technical field
The present invention relates to a kind of workpiece machining tool, relate in particular to a kind of belt pulley forging mold.
Background technology
Belt pulley belongs to dish hub class part, and general relative size is bigger, on the manufacturing process generally based on casting or forge.Because casting character is better, belt pulley generally adopts cast iron, and seldom uses cast steel.In the manufacture process, adopt two die castings that are harmonious usually, the belt pulley that this method is made produces " overlap ", needs further processing to remove.In addition, the mould reclamation rate is also lower, and the production material cost is higher.
Summary of the invention
The invention provides a kind of belt pulley forging mold, be applicable to that the Surface Machining of the shaft-like work of length more than 10cm is handled, increase the hardness of surface of the work.
The technical solution used in the present invention is as follows:
A kind of belt pulley forging mold comprises stress overcoat, shape chamber module, base plate and pressure head module.
Shape chamber module comprises toroidal cavity, at the toroidal cavity inwall annular die cavity is set, and the plane of the opening of annular die cavity is lower than the plane of the opening 25mm of toroidal cavity.
The pressure head module comprises the moulding annular groove, moulding annular groove outer wall and toroidal cavity inwall matched in clearance, and the plane of the opening of moulding annular groove plane of the opening and annular die cavity is fitted.
Stress overcoat and shape chamber module tight fit are located at outside the module of shape chamber.Base plate is placed on shape chamber module one end.
The stress overcoat adopts No. 45 steel, and shape chamber module, base plate and pressure head module all adopt the H13 steel.
The belt pulley non-trimming that adopts mould provided by the invention to make produces, the recyclable utilization of mould, and long service life, cost is low.
Description of drawings
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of belt pulley forging mold of the present invention;
Fig. 2 is the structural representation of pressure head mould of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, the belt pulley forging mold comprises stress overcoat 1, and itself and shape chamber module 2 tight fits are located at outside the module of shape chamber.Shape chamber module 2 comprises toroidal cavity 21, at the toroidal cavity inwall annular die cavity 22 is set, and the plane of the opening 24 that the plane of the opening 23 of annular die cavity is lower than toroidal cavity is of a size of 25mm.Base plate 4 is placed on shape chamber module 2 one ends.
Pressure head module 3 comprises moulding annular groove 31, moulding annular groove outer wall and toroidal cavity inwall matched in clearance, and moulding annular groove plane of the opening 32 is fitted with the plane of the opening 23 of annular die cavity.
The stress overcoat adopts No. 45 steel, and shape chamber module, base plate and pressure head module all adopt the H13 steel.
Change by the shape chamber module to different model, realize using repeatedly, and be applicable to the manufacturing of different model belt pulleys.The belt pulley non-trimming of manufacturing produces, and need not subsequent machining technology.The belt pulley forging mold can be made 23-24 spare belt pulley, compares with the output of existing mold (13) and improves nearly 1 times, and materials only need 0.3-0.4 kilogram steel, and cost significantly reduces.
