CN102862036A - Manufacturing process of rolling wheel for machining and forming bearing forging piece - Google Patents

Abstract

The invention discloses a manufacturing process of a rolling wheel for machining and forming a bearing forging piece, and the manufacturing process comprises the following steps of step 1, arranging angles on two sides of a rolling wheel groove of the rolling wheel, and ensuring the wall thickness of the rolling wheel to be in proportion with the arranged angles; step 2, manufacturing a rolling wheel groove sample plate which is consistent with the shape of the rolling wheel groove; and step 3, utilizing the rolling wheel groove sample plate to measure the shape of the rolling wheel groove, and carrying out the subsequent machining if the shape of the rolling wheel groove is consistent with that of the rolling wheel groove sample plate. The manufacturing process is simple to machine, convenient to produce and capable of effectively improving the productivity of the bearing forging piece and the product quality.

Description

A kind of roll milling wheel manufacturing process that shapes for bearing forging

 

Technical field

The present invention relates to a kind of manufacturing process of roll milling wheel, be specifically related to a kind of roll milling wheel manufacturing process that shapes for bearing forging.

 

Background technology

Shaping of bearing forging, depend primarily on Design of Dies processing, the mould key is rolling wheel design processing (forging shape, quality depend on the rolling wheel grooved), when the design rolling wheel: 1, will consider whether the rolling wheel groove shape is consistent with lasso forging outer contour shape; 2, to consider that whether forging stock can enter race smoothly, withdraws from race; 3, to consider in grinding the expansion process whether metal flow produces pit to, forging end face; 4, to consider the rolling wheel bearing capacity.Because the restriction of above-mentioned requirements causes bearing forging difficulty of processing in actual production process larger, productivity ratio is very low.

 

Summary of the invention

The deficiency that technology is arranged on the object of the invention is to overcome provides a kind of roll milling wheel manufacturing process that shapes for bearing forging.

A kind of roll milling wheel manufacturing process that shapes for bearing forging comprises the steps:

Step 1, offer angle on the race both sides of rolling of rolling wheel, the wall thickness of rolling wheel is directly proportional with offering angle;

Step 2, manufacturing are consistent with the rolling wheel groove shape rolls the race model;

Step 3, measure the rolling wheel groove shape with rolling the race model, when consistent, carry out following process.

The present invention processes simply, and is easy to make, can effectively improve bearing forging productivity ratio and product quality.

 

Description of drawings

Fig. 1 is the structural representation of rolling wheel.

 

The specific embodiment

 

A kind of roll milling wheel manufacturing process that shapes for bearing forging provided by the invention,

Comprise the steps:

1, design according to forging wall thickness and distortion size, provides and rolls race both sides certain angles (referring to Fig. 1) during rolling wheel, and generally speaking, wall is thicker, is out of shape greatlyr, and angle is larger;

2, manufacturing is consistent with the rolling wheel groove shape rolls the race model;

3, measure the rolling wheel groove shape with rolling the race model, when consistent, carry out following process.

Claims (1)

1. one kind is used for the roll milling wheel manufacturing process that bearing forging shapes, and it is characterized in that: comprise the steps:

Step 1, offer angle on the race both sides of rolling of rolling wheel, the wall thickness of rolling wheel is directly proportional with offering angle;

Step 2, manufacturing are consistent with the rolling wheel groove shape rolls the race model;

Step 3, measure the rolling wheel groove shape with rolling the race model, when consistent, carry out following process.
