Description

Forming mode of stainless steel upset product
Technical Field
The invention relates to the technical field of wedge-shaped block upsetting forming, in particular to a forming mode of a stainless steel upsetting product.
Background
The wedge-shaped block is processed as shown in figure 1, the top of the wedge-shaped block is an inclined plane which is inclined leftwards, the top edges of the left side and the right side of the wedge-shaped block are arc-shaped parts, a workpiece used for forming the wedge-shaped block is a stainless steel rectangular block, the existing forming process is that an inclined line is drawn on the end face of the stainless steel rectangular block, then a worker cuts the rectangular block along the inclined line, so that a semi-finished wedge-shaped block is obtained, the worker finally polishes the left edge and the right edge of the inclined plane in a polishing mode to form the arc-shaped parts, and finally the finished wedge-shaped block is processed, but the arc-shaped parts on the right side collapse in the processing method as shown in figure 2, and the processing quality of the product is. In addition, the existing form of single piece processing not only reduces the production efficiency, but also can not realize batch production.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a forming mode of stainless steel upsetting products, which has the advantages of simple process, improved upsetting quality, improved upsetting efficiency and realization of mass production of the products.
The purpose of the invention is realized by the following technical scheme: a forming mode of a stainless steel upset product comprises the following steps:
s1, upsetting and forming the semi-finished wedge block:
s11, arranging the stainless steel blank blocks on the material frame along a straight line to form a strip, and assembling the stainless steel blank blocks at the head end of the strip on the top surface of the upsetting female die;
s12, controlling the punching machine to start, driving the punch and the upsetting male die below the punch to move downwards by the punching machine, pressing the inclined plane of the upsetting male die on the top of the stainless steel blank block, and forming an inclined plane matched with the inclined plane on the top of the stainless steel blank block so as to obtain a semi-finished wedge-shaped block matched with the inclined plane;
s2, upsetting and forming the finished wedge-shaped block:
s21, along with the movement of the strip, the semi-finished wedge block tool enters the top surface of the groove of the fine blanking female die of the punching machine;
s22, controlling a punching machine to start, wherein the punching machine drives a punch and a fine blanking punch A and a fine blanking punch B below the punch to respectively punch the left end part and the right end part of the semi-finished wedge block, so that materials on the left side and the right side of the semi-finished wedge block are punched, and the distance between the fine blanking punch A and the fine blanking punch B is gradually reduced along with the continuous movement of a strip material, so that the width of the semi-finished wedge block is gradually reduced, and finally the required finished wedge block is obtained;
and S3, unloading the finished wedge-shaped block from the fine blanking female die by adopting an unloading plate.
The top surface of the upsetting concave die is flat.
The invention has the following advantages: the invention has simple process, improves the upsetting quality and the upsetting efficiency; because the left and right materials of the stainless steel blank block are gradually punched, the arc-shaped part does not need to be cut firstly and then manually polished, and the corner collapse R of the product caused by blanking is reduced by adopting a multiple fine blanking process, so that the processing quality of the finished wedge block is greatly improved.

Detailed Description
The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:
as shown in fig. 3-4. A forming mode of a stainless steel upset product comprises the following steps:
s1, upsetting and forming the semi-finished wedge block:
s11, arranging the stainless steel blank blocks 1 on a material frame along a straight line to form a strip, and assembling the stainless steel blank blocks 1 at the head end of the strip on the top surface of the upsetting female die 2;
s12, controlling the punching machine to start, driving the punch and the upsetting male die 4 below the punch to move downwards by the punching machine, pressing the inclined plane 3 of the upsetting male die 4 on the top of the stainless steel blank block 1, and forming an inclined plane matched with the inclined plane 3 on the top of the stainless steel blank block 1 so as to obtain a semi-finished wedge-shaped block matched with the inclined plane 3;
s2, upsetting and forming the finished wedge-shaped block:
s21, along with the movement of the strip, the semi-finished wedge-shaped block 5 enters the top surface of the groove of the fine blanking female die 6 of the punching machine;
s22, controlling a punching machine to start, wherein the punching machine drives a punch and a fine blanking punch A7 and a fine blanking punch B8 below the punch to respectively punch the left end part and the right end part of the semi-finished wedge block 5, so that materials on the left side and the right side of the semi-finished wedge block 5 are punched, and along with the continuous movement of a strip, the distance between the fine blanking punch A7 and the fine blanking punch B8 is gradually reduced, so that the width of the semi-finished wedge block 5 is gradually reduced, and finally the required finished wedge block is obtained; in the whole forming process, materials on the left side and the right side of the stainless steel blank block are gradually punched, the arc-shaped part does not need to be cut firstly and then manually polished, the process of fine blanking for multiple times is adopted, the collapse angle R of a product caused by blanking is reduced, and the processing quality of a finished product wedge block is greatly improved.
