Abstract

The invention discloses a production process of a body flange. The product process comprises the following steps: a, material choosing: choosing a long-strip-shaped steel plate with the corresponding specifications according to the required dimension of the body flange; b, edge rolling: rolling the steel plate into an annular flange ring through a flange edge rolling machine; c, welding: welding an interface of the rolled flange ring; d, pressing: pressing the flange ring to be flat through a pressing machine; e, machining: machining the flange ring pressed to be flat through a lathe to form an inner circle, an outer circle, a plane and a boss; and f, drilling: drilling through a drilling machine to form bolt holes. The long-strip-shaped steel plate serves as the raw material, and the production process comprises edge rolling, welding, pressing, machining and drilling, and compared with traditional casting process, the production process is high in material utilization rate, saves materials, reduces cost, enables machining to be convenient and easy, greatly reduces labor intensity of workers and improves production efficiency.

Description

A kind of production technology of body flange
Technical field
The present invention relates to a kind of production technology of body flange.
Background technology
At present, make the body flange part in the industry, owing to be subjected to the restriction of many factors, the molding mode that generally adopts be with blank, be forged into annulus after, with lathe be machined to need to size.Yet, this kind processing mode, its allowance that need to reserve is larger, thus so that stock utilization is low, and its processing cost is high, production efficiency is low, and not only labor intensive, material resources, and also product qualified rate is low.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of production technology of body flange is provided, low to solve original body flange part processing mode stock utilization, processing cost is high, the problem that production efficiency is low.
The objective of the invention is to be achieved through the following technical solutions:
A kind of production technology of body flange may further comprise the steps:
A, selection: according to the body flange of required size, select the steel plate of the strip structure of dimension;
B, volume circle: utilize flange rolling machine roll of steel plate to be made the flange circle of circulus;
C, welding: the interface of rolling up the flange circle after justifying is welded;
D, pressing: the flange circle is flattened with forcing press;
E, Vehicle Processing: with lathe the flange circle after flattening is machined, process inside and outside circle, plane and boss;
F, boring: utilize drilling machine to hole, process bolt hole.
Further, the flange rolling machine among the described step b is arc line descending type three-roller section bending machine.
Further, described arc line descending type three-roller section bending machine comprises a home roll and two limit rollers, and described home roll diameter is 240mm, and described limit roller diameter is 220mm.
Further, adopt automatic welding to weld among the described step c.
Further, described step c also comprises weld grinding smooth.
Beneficial effect of the present invention is: it is raw material that the production technology of described body flange adopts the steel plate of strip structure, through rolling up circle, welding, pressing, Vehicle Processing, bore process moulding, the processing mode of the conventional cast of comparing, not only stock utilization is high, save material, reduce cost, and it is easy to process simple, greatly reduce workman's labour intensity, improved production efficiency.

The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
See also Figure 1 and Figure 2, Fig. 1 is the process chart of the production technology of a kind of body flange of the present invention, and Fig. 2 is arc line descending type three-roller section bending machine structural representation of the present invention.In present embodiment, a kind of production technology of body flange may further comprise the steps:
A, selection: according to the body flange of required size, select the steel plate 1 of the strip structure of dimension;
B, volume circle: utilize arc line descending type three-roller section bending machine that steel plate 1 is rolled up circle, described arc line descending type three-roller section bending machine comprises a home roll 2 and two limit rollers 3, described home roll 2 diameters are 240mm, described limit roller 3 diameters are 220mm, the volume bowlder, oil cylinder 4 promotes limit roller 3 downwards, with rolling up circle behind steel plate 1 chucking, rolls into the flange circle of circulus;
C, welding: adopt automatic welding that the interface of rolling up the flange circle after justifying is welded, after the welding that weld grinding is smooth;
D, pressing: the flange circle is flattened with forcing press;
E, Vehicle Processing: with lathe the flange circle after flattening is machined, process inside and outside circle, plane and boss;
F, boring: utilize drilling machine to hole, process bolt hole.
Adopt above-mentioned technique to make the body flange, its product qualified rate is high, and its stock utilization is high, saves material, reduces cost, and in addition, this kind processing mode is simple and convenient, effectively reduces labour intensity, has improved production efficiency.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
