Abstract
The invention discloses a machining die of an automobile oil pump bracket spline, which comprises an upper punch, a lower punch, a cavity die, a die case and a filler block, wherein the upper punch isa flat-head punch; a spline punch is arranged at the top end of the lower punch; the machining die also comprises a spring, the spring is fixed in the filler block, and one end of the spring is connected with the cavity die; the cavity die is a floating cavity die which is connected with the die case and is capable of reciprocating along the die case; a hollow cavity is formed by the floating cavity die, the die case and the filler block; a T-shaped structure workpiece cavity is arranged in the middle of the floating cavity die; and the diameter of the spline punch is smaller than the cavitydiameter at the lower part of the T-shaped structure workpiece cavity. The machining die of the invention allows the extrusion forming of the oil pump bracket seat, the coupling lever and the spline in the coupling lever to be completed by one-step, thus reducing the production cost and improving the production efficiency.
Description
Technical field
The present invention 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 present invention solves 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 present invention 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 present invention has rational in infrastructure, reasonably carries out volume by metal flowing forming rule and distributes, and extrusion rack seat and coupling lever and the moulding of bar internal spline reduce production costs, and improved production efficiency.
