Abstract
The invention discloses a technical method for forming a semi-axle housing tube for a large-diameter flange. The technical method comprises the following steps of: sawing hot-rolled round steel serving as a blank, heating, and upsetting by using an extruding machine; performing rotary forging for forming by using a rotary forging press; and performing forward extrusion once and backward extrusion to form a forged piece of the semi-axle housing tube. According to technical method, in the maximum process step of forming force required by the semi-axle housing tube, the flange is formed by the rotary forging press; and only an outer step axle and an inner step hole are formed when the head flange is formed by the rotary forging and is extruded. The technical method has the advantages that: the full filling of flange corners is ensured effectively, the investment cost of equipment is reduced effectively, the process difficulty of the subsequent extrusion process step is reduced, the coaxiality of finished products is easy to ensure, and the production cost of the forged piece is reduced while the yield of the products is improved.
Description
Technical field
The present invention relates to a kind of forming technique method of major diameter flange axle tube, belong to metalwork plastic forming technology field.
Background technology
Axle tube is the heavy part in pass of bearing heavy load on the truck back axle, requires to withstand shocks alternate load, and condition of work is very abominable, so require axle tube that the favorable mechanical performance is arranged.Heavy truck bridge with the flange of axle tube near end face; The domestic present technology three work step hot extrusions technology that adopt more; But it is more that technology itself is still deposited the relatively poor machine-finish allowance that causes of axiality, and the shaping difficulty is bigger in the bight, needs the technical barrier of repair by welding forging.For the bigger product of flange diameter; Needing bigger pressure could be shaped; And the traditional hot extrusion technique often all will apply forming pressure to flange at two work steps, and this just requires equipment configuration tonnage higher, and mostly the equipment of production unit configuration at present is the hydraulic press that 1600T is above.The hydraulic press of this type of tonnage has high input, production cost is high, simultaneously, is prone to cause after the moulding part flange angle idol shortcomings such as not full, as influence axiality precision, technological design difficulty height, forming pressure is big, die life is short that are shaped.
Summary of the invention
To the shortcoming of existing axle tube manufacturing process, the present invention provides a kind of forming technique method of novel major diameter flange axle tube.
To achieve these goals, the measure that the present invention taked:
A kind of forming technique method of major diameter flange axle tube, said forming technique method are to be blank with the hot rolled circular steel, and blank is carried out heat treated after through sawing, and the heading work step is accomplished through extruder in the heating back; And then pass through rotary forging press its pendulum is rolled over shaping; At last, accomplish the axle tube forging forming through a forward extrusion and a backward extrusion work step;
Said forming technique method is accomplished the maximum work step of the required plastic force of axle tube and is shaped through rotary forging press;
Said forming technique method is only accomplished outer step axle and interior stepped hole shaping action after passing through to accomplish earlier pendulum rolling shaping head flanges when pushing work step again;
Each work step of said forming technique method is accomplished through the orderly variation of optimizing geometry and is shaped.
The afterbody of the backward extrusion part of said forming technique method has interior step.
Beneficial effect of the present invention: the filling that effectively guarantees flange angle idol is full, effectively reduces equipment investment cost; Meanwhile, reduce the technology difficulty of follow-up extruding work step, and helped guaranteeing the axiality of finished product, effectively reduced the forging production cost when improving product percent of pass.

The specific embodiment
A kind of forming technique method of major diameter flange axle tube, said forming technique method are to be blank with the hot rolled circular steel, and blank is carried out heat treated after through sawing, and the heading work step is accomplished through extruder in the heating back; And then pass through rotary forging press its pendulum is rolled over shaping; At last, accomplish the axle tube forging forming through a forward extrusion and a backward extrusion work step; In the actual implementation process of patent, as shown in Figure 1, this forging is complex-shaped; Forging head flanges outside dimension is φ 202mm, and bar portion is the step axle, and smallest shaft portion diameter is φ 88mm; Forging length is 371mm, adds that endoporus is shaped and the required stroke of pickup, requires device travel greater than 1000mm; Die shut height is greater than 700mm, and enough big workbench is arranged; Therefore select for use big stroke hydraulic machine to accomplish forward extrusion and backward extrusion work step; Bigger to the head flanges diameter, plastic force is bigger, so said forming technique method is accomplished the partially-formed action of flange with the maximum work step of the required plastic force of axle tube through rotary forging press; Said forming technique method is only accomplished outer step axle and interior stepped hole shaping action after passing through to accomplish earlier pendulum rolling shaping head flanges when pushing work step again; Each work step of said forming technique method is accomplished through the orderly variation of optimizing geometry and is shaped.Concrete operations step of the present invention is: the first step, get the hot rolled circular steel of suitable specification, and on the band saw lathe, be sawn into the bar of Len req, as shown in Figure 2; Second goes on foot, and bar is filled in the heating in medium frequency stove heated, and be heated to forging temperature; The 3rd step was put into the bar after the heating in the heading mould, and the primer fluid press is accomplished the heading work step with bar, and the back that is shaped is as shown in Figure 3; The 4th step was put into the shaping blank of accomplishing the heading work step in the open-close module on the 260T rotary forging press immediately, and the head flanges pendulum rolling of accomplishing axle tube is shaped, and the back that is shaped is as shown in Figure 4; The 5th goes on foot, and the blank of accomplishing institute's head flanges pendulum rolling shaping is put into completion forward extrusion shaping work step in the forward extrusion mould an actor's rendering of an operatic tune on the 630T hydraulic press, and the back that is shaped is as shown in Figure 5; In the 6th step, the blank that forward extrusion is shaped is put in the indirect-extrusion mould an actor's rendering of an operatic tune on the 630T hydraulic press, and final extrusion molding is as shown in Figure 1 for becoming forging.
Those skilled in the art's simple change and replacement all are within protection scope of the present invention in this area.
