Abstract

The utility model discloses an automobile oil-pump bracket spline processing mould consisting of an upper punch, a lower punch, a concave die, a concave die casing and a filling block. The upper punch is a flat head punch. A spline punch is arranged on the top of the lower punch which also includes a spring fixed in the filling block with one end of the spring connected with the concave die. The concave die is a floating concave die which is connected with the concave die casing and can move up and down along the concave die casing. The floating concave die, the concave die casing and the filling block form a cavity. A work-piece cavity with a T-shaped structure is arranged in the middle of the floating concave die. The diameter of the spline punch is less than the lower cavity diameter of the work-piece cavity with a T-shaped structure. By using the mould, a bracket base of the oil pump bracket, a coupling lever and the spline in the lever can be shaped by one time extrusion, which reduces production cost as well as improves production efficiency.

Description

Vehicle oil pump bracket spline processing die

Technical field

The utility model relates to a kind of vehicle oil pump bracket spline processing die, especially relate to a kind of by metal flowing forming rule, the particular manufacturing craft of extrusion rack seat and coupling lever and the moulding of bar internal spline.

Background technology

Prior art is produced oil pump bracket, and manufacturing firm all adopts precision forging blank technology both at home and abroad, can satisfy required precision like this, has reduced manufacturing cost and cycle again, also meets the trend of world today's development of manufacturing simultaneously.The processing mode that oil pump bracket finish forge spare adopts at present generally processes by repeatedly replacing with bed die, owing to adopt how secondary mould, more mold exchange increases the production cycle and the working strength of workers of workpiece.

Summary of the invention

The utility model mainly is to solve existing the deficiencies in the prior art, a kind of vehicle oil pump bracket spline processing die is provided, use this mould an extrusion modling of oil pump bracket can not to be needed more mold exchange, the particular manufacturing craft of extrusion rack seat and coupling lever and the moulding of bar internal spline.

The utility model is achieved by the following technical solution: vehicle oil pump bracket spline processing die, comprise upper punch, low punch, die, die case, fill block, and described upper punch is the tack drift; The top of described low punch is provided with the spline drift, and it also comprises spring, and described spring is fixed in the fill block, and an end of spring links to each other with die; Described die is a floating cavity die, and described floating cavity die links to each other with die case and can move up and down along die case; Described floating cavity die, die case and fill block constitute cavity; Be provided with the workpiece chamber of T shape structure in the middle of the described floating cavity die; The diameter of described spline drift is less than the lower chamber footpath in T shape structure workpiece chamber.

Described spring is a 4-8 steel spring.

Described spline drift is three spline drifts.

Described spline drift is six spline drifts.

The utlity model has rational in infrastructurely, reasonably carry out volume by metal flowing forming rule and distribute, extrusion rack seat and coupling lever and the moulding of bar internal spline reduce production costs, and have improved production efficiency.
