Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 2-3, an improved structure for machining a steel part comprises a raw material 1, a blank 2 and a finished product 3, wherein the blank 2 comprises a first region and a second region, a step surface is formed at the joint of the first region and the second region, a first groove is annularly arranged at one side of the middle part of the step surface, which is close to the axial lead of the first region, a second groove is arranged at the center of the bottom of the second region, and a third groove is arranged at the outer side of the second groove.

The first groove of the primary blank 2 is an annular groove with a lower groove width smaller than that of the upper groove width, so that the width from the upper groove edge to the outer wall of the second area is smaller than that from the lower groove edge to the second area, on one hand, the first area is convenient to process, on the other hand, one side of the middle part of the step surface, far away from the central line of the first area, is convenient to process, and subsequent processing steps are simplified.

Wherein, the groove two of primary blank 2 is the trapezoidal cylinder recess that the groove width is less than the groove width down for last groove width, compares in current primary blank 2, and the design of groove two makes the groove two parts of the primary blank 2 after the improvement simplify toward the process of finished product 3 processing for get rid of unnecessary leftover bits can, greatly reduced the degree of difficulty of processing, also played the effect of saving raw and other materials simultaneously.

Wherein, the third groove of first base 2 is that the distance between one side that the last groove limit is close to 2 axial lead of first base to one side that the last groove limit is close to 2 second region edges of first base is less than the distance between one side that the lower groove limit is close to 2 axial lead of first base to one side that the lower groove limit is close to 2 second region edges of first base, compare in current first base 2, the design of third groove makes the shape of 2 bottom both sides of first base more adapt with the shape of 3 bottom both sides of finished product, it is similar with the groove two to add man-hour, only need according to finished product 3 the shape get rid of unnecessary leftover bits can, processing steps have been simplified.

The working principle is as follows: during the use, through putting into last mould with raw materials 1, put into the lower mould with the primary blank mould, detain last mould and lower mould for during raw materials 1 in last mould flows into the primary blank mould, accomplish forging and pressing primary blank 2, carry out finish turning with the primary blank 2 that the forging and pressing is good again, thereby accomplish the production of product.
