Abstract

A side cutting die for a steering nut comprises a side cutting female die and a puncher chip male die, wherein the side cutting female die and the puncher chip male die correspond in an up and down position. The side cutting female die is divided into two half dies from the middle, a steering nut cavity outer contour is arranged in the center of the side cutting female die, and a female die cutting edge is welded on the contour. The puncher chip male die is a male die corresponding to the cavity of the side cutting female die, and the clearance between the side cutting female die and the puncher chip male die is 1.0mm. When the side cutting die for the steering nut is manufactured, cut die blocks are used for manufacturing the puncher chip male die directly, materials are saved, and the identical degree of the shape of the puncher chip male die and the female die can be guaranteed.

Description

A kind of steering nut shaving die

Technical field

The utility model relates to a kind of shaving die.

Background technology

Edger and drift mould, it is the instrument of removing the unnecessary overlap of forging in forging process, these two moulds satisfied can not, product appearance is played an important role, for the steering nut series products, due to the shape matching complexity, bothersome effort when its shaving die manufacture and refurbishment process, its manufacturing speed is larger on whole product development progress and production efficiency impact, at present, this edger and drift mould are general adopts two modules to process separately, and processing cost is high.

The utility model content

The purpose of this utility model is to provide a kind of steering nut shaving die, facilitates mould manufacture and renovation, cuts down finished cost.

The technical solution of the utility model is:

A kind of steering nut shaving die, it comprises trim die and the drift punch that upper-lower position is corresponding, the mold halves of described trim die for separating from centre, the center of described trim die is provided with a steering nut die cavity outline, is welded with cutting edge of die on described profile; Described drift punch is the punch corresponding with the die cavity of trim die, and the gap between trim die and drift punch is 1.0mm.

The width of cutting edge of die is 12-15mm, cutting edge thickness 4-6mm.

The width of cutting edge of die is 14mm, cutting edge thickness 4mm.

When the utility model is manufactured, directly utilize the module making of cutting to become the drift punch, both saved material, can guarantee again the degree of agreement of drift punch shape and die.The size of cutting edge can guarantee to add man-hour, fast to the workpiece trimming.The gap of drift and die can reach 1.0mm, and does not affect production, and generally gap requirement is 0.02mm.Simple in structure, mould manufacture and processing cost are also lower.

The accompanying drawing explanation

Fig. 1 is the structural representation of trim die of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the structural representation of drift punch.

The specific embodiment

As shown in Figure 1,3, the utility model comprises the corresponding trim die of upper-lower position 1 and drift punch 3.The center of trim die 1 has a steering nut die cavity outline, the mold halves 4,5 of trim die 1 for separating from centre.

As shown in Figure 1, 2, be welded with cutting edge of die 2 on the profile of trim die 1, the width of cutting edge of die 2 is that 12-15mm(the present embodiment is 14mm), cutting edge of die 2 thickness 4-6mm(the present embodiment are 4mm), it is 4mm that cutting edge of die 2 is received 4-6mm(the present embodiment inward).

Manufacturing process: the shape cutting along the steering nut outline a module with the wire cutting machine device, the middle part of module is used for making drift punch 3, with numerical control mill the middle part of module the pocket machining according to steering nut, what obtain is drift punch 3.

The remaining part of module is exactly trim die, need cut into two halves from centre, forms mold halves 4,5, and the two is exactly trim die 1 altogether.The gap of drift punch 3 and trim die 1 is 1.0mm.

Claims

1. a steering nut shaving die, it is characterized in that: it comprises trim die and the drift punch that upper-lower position is corresponding, the mold halves of described trim die for separating from centre, the center of described trim die is provided with a steering nut die cavity outline, on described profile, is welded with cutting edge of die; Described drift punch is the punch corresponding with the die cavity of trim die, and the gap between trim die and drift punch is 1.0mm.

2. steering nut shaving die according to claim 1, it is characterized in that: the width of cutting edge of die is 12-15mm, cutting edge thickness 4-6mm.

3. steering nut shaving die according to claim 2, it is characterized in that: the width of cutting edge of die is 14mm, cutting edge thickness 4mm.
