Abstract
A belt wheel forging die comprises a stress external sleeve, a section cavity die member, a base plate and a press head die member, wherein the section cavity die member comprises an annular cavity; the inner wall of the annular cavity is provided with an annular die groove; an open plane of the annular die groove is 25mm lower than an open plane of the annular cavity; the press head die member comprises a forming ring groove; the external wall of the forming ring groove is in a clearance fit with the inner wall of the annular cavity; and an open plane of the forming ring groove is applying to the open plane of the annular die groove. A belt wheel without trimmings can be produced by the belt wheel forging die; and the die can be recycled with long service life and low cost.
Description
Technical field
The utility model relates to a kind of workpiece machining tool, relates in particular to a kind of belt pulley forging mold.
Background technology
Belt pulley belongs to hub class part, and general relative size is larger, in manufacturing process generally with casting or be forged to master.Because casting character is better, belt pulley generally adopts cast iron, and seldom uses cast steel.In manufacture process, conventionally adopt two die castings that are harmonious, the belt pulley that this method is manufactured produces " overlap ", needs further processing to remove.In addition, mould reclamation rate is also lower, and production material cost is higher.
Utility model content
The utility model provides a kind of belt pulley forging mold, and the Surface Machining that is applicable to the shaft-like work of length more than 10cm is processed, and increases the hardness of surface of the work.
The technical solution adopted in the utility model is as follows:
A belt pulley forging mold, comprises stress overcoat, shape chamber module, base plate and pressure head module.
Shape chamber module comprises toroidal cavity, at 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.
Pressure head module comprises moulding annular groove, moulding annular groove outer wall and toroidal cavity inwall matched in clearance, the plane of the opening laminating of forming ring channel opening plane and annular die cavity.
Stress overcoat and shape chamber module tight fit, be located at outside the module of shape chamber.Base plate is placed on module one end, shape chamber.
Stress overcoat adopts No. 45 steel, and shape chamber module, base plate and pressure head module all adopt H13 steel.
The belt pulley non-trimming that the mould that employing the utility model provides is manufactured produces, mould recoverable, and long service life, cost is low.
Accompanying drawing explanation
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of the utility model belt pulley forging mold;
Fig. 2 is the structural representation of the utility model pressure head mould.
The specific embodiment
As depicted in figs. 1 and 2, 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 toroidal cavity inwall, annular die cavity 22 is set, and the plane of the opening 23 of annular die cavity is of a size of 25mm lower than the plane of the opening 24 of toroidal cavity.Base plate 4 is placed on module 2 one end, shape chamber.
Stress overcoat adopts No. 45 steel, and shape chamber module, base plate and pressure head module all adopt H13 steel.
By the shape chamber module to different model, change, realize Reusability, and be applicable to the manufacture of different model belt pulleys.The belt pulley non-trimming of manufacturing produces, without subsequent machining technology.Belt pulley forging mold can be manufactured 23-24 part belt pulley, compares improve nearly 1 times with the output of existing mold (13), and materials only need 0.3-0.4 kilogram of steel, and cost significantly reduces.
Claims (2)
