Abstract
The present invention proposes a kind of stock utilization height, good product quality, be fit to produce in enormous quantities, with the manufacturing technique method of the axle housing stiffening ring of the good welding performance of axle housing.Its technical scheme is: the material of axle housing stiffening ring adopts low-alloy, the steps include: (1) blanking: adopt round steel, cut into blank by the size of axle housing stiffening ring; (2) then blank is cut into two identical semicircle pieces; (3) finished edge on the otch two ends of semicircle piece, the semicircle piece forms the press-bending blank; (4) the press-bending blank is configured as the semiellipse ring body on bending die; (5) then the semiellipse ring body is matched in twos, the double end butt welding is an oval ring body, and the groove butt joint on the semicircle piece is groove, reconditioning weld seam; (6) heat: the temperature that oval ring body is heated to 900～1100 ℃; (7) die-forging forming: the oval ring body after the heating is placed on that forging and molding is the axle housing stiffening ring with final products size on the forging mold.
Description
Technical field
The present invention relates to the manufacturing technique method of axle housing stiffening ring.
Background technology
Stiffening ring is the strength member that the cargo vehicle back axle dashes the weldering axle housing, and the principal character of this product is: 1. product design is that the cross section is the annulus of rectangle, and circle diameter is big (about 500mm); 2. the product material requires with low alloy steel plate good welding performance is arranged.
The existing manufacturing technique method of stiffening ring mainly contains following two kinds:
First kind: raw material are low carbon steel plate, use the plasma excision forming, machined deburring then, chamfering.
Second kind: hot investment casting.
The advantage of first kind of manufacturing technique method is: equipment drops into little, and product changes that shape is fast, good welding performance.Shortcoming is: waste of raw materials is too big, utilization rate is little, working (machining) efficiency is low.
The advantage of second kind of manufacturing technique method is: the stock utilization height, do not need machined.Shortcoming is: casting flaw control is difficult, welding performance is poor.
Summary of the invention
The present invention proposes a kind of manufacturing technique method of axle housing stiffening ring, can reach stock utilization height, good product quality, be fit to produce in enormous quantities, with the purpose of the good welding performance of axle housing.
Inventive concept of the present invention is: adopt die-forging forming axle housing stiffening ring.
Technical scheme of the present invention is: the manufacturing technique method of axle housing stiffening ring, the material of axle housing stiffening ring adopts low-alloy, the steps include:
(1), blanking: adopt round steel, cut into blank by the size of axle housing stiffening ring;
(2), then blank is cut into two identical semicircle pieces;
(3), on the otch two ends of semicircle piece finished edge, the semicircle piece forms the press-bending blank;
(4), the press-bending blank is configured as the semiellipse ring body on bending die;
(5), then the semiellipse ring body is matched in twos, the double end butt welding is an oval ring body, and the groove butt joint on the semicircle piece is groove, reconditioning weld seam;
(6) heat: the temperature that oval ring body is heated to 900～1100 ℃;
(7) die-forging forming: the oval ring body after the heating is placed on that forging and molding is the axle housing stiffening ring with final products size on the forging mold.
Beneficial effect: process of the present invention utilizes die-forging forming to realize, has the following advantages:
1. the product material is a low-alloy steel, and good welding performance is arranged.
2. product design is generated by die forging, and good product quality has good stability;
3. utilization rate of raw materials height, utilization rate is greater than 90%;
4. do not need machined;
5. speed of production is about 2000 of per tour, is fit to produce in enormous quantities;
6. production cost is lower than existing manufacturing technique method.

(2), then blank is cut into two identical semicircle pieces; The equipment that adopts is punch press, and the frock of employing is a knife edge die;
(3), on the otch two ends of semicircle piece finished edge, the semicircle piece forms the press-bending blank; The equipment that adopts is milling machine;
(4), the press-bending blank is configured as the semiellipse ring body on bending die, as shown in Figure 1, the just blank of the stiffening ring semiellipse ring body 1 that is divided into along center line A and the blank of stiffening ring semiellipse ring body 2; The equipment that adopts is hydraulic press, and the frock of employing is the bent into shape mould;
(5), then the semiellipse ring body is matched in twos, the double end butt welding is an oval ring body, and the groove butt joint on the semicircle piece is groove, reconditioning weld seam; The equipment that welding is adopted is butt welding machine;
(6) heat: the temperature that oval ring body is heated to 900～1100 ℃; The equipment that adopts is induction heater;
(7) die-forging forming: the oval ring body after the heating is placed on that forging and molding is the axle housing stiffening ring with final products size on the forging mold, promptly is configured as the axle housing stiffening ring of shape shown in Figure 1; The equipment that adopts is forcing press, and the frock of employing is a hot-forging die.
