Abstract
The invention discloses a manufacturing process of a half shaft with a flange plate, which comprises the following steps of: 1, raw material preparation: cutting a certain length of moulded steel or continuously cast steel with same thickness as a rod part of the half shaft as raw materials; 2, spline section collection and blanking: collecting and forming one end of the raw materials, such as blank splines, by using a friction press or horizontal forging and upsetting machine after locally heated to 1150-1200 DEG C for first time, upsetting until reaching the spline size; 3, flange section blanking: collecting and blanking by using the friction press or horizontal forging and upsetting machine after locally heated for secondary time, heating the other end (a blank flange) of the raw materials to 1150-1200 DEG C for secondary time and carrying out first time pre-setting on the flange blank; and 4, flange section forming: rocking-rolling the flange blank into the flange plate on a rocking rolling machine directly without heating when the residue temperature of the preset flange blank is 950-1050 DEG C. After the flange section is heated and preset into the flange blank, the flange plate is rocking-rolled by using the residual temperature, thus the possibility of generating forged cracks is reduced, the purpose of improving the workpiece quality is achieved, and the electricity consumption is lowered.
Description
Technical field
The present invention relates to a kind of axial workpiece manufacturing process, particularly a kind of automobile belongs to mechanical field with the manufacturing process of flanged dish semiaxis.
Background technology
The method of manufacturing technology of traditional flanged dish semiaxis is that " three fire " forges moulding, and the technological process brief introduction is as follows: referring to Fig. 1-1, Fig. 1-2, Fig. 1-3 and Fig. 1-4, Fig. 1-1 is a raw material; Fig. 1-2 is the poly-material of spline segment; Fig. 1-3 flange section base; The moulding of Fig. 1-4 flange section.1. raw material: select for use with thick moulded steel such as half shafts portion or continuous casting steel as raw material; 2. poly-material of spline segment and base: raw material one end, as the blank spline, through after the local heat to 1200 for the first time ℃, with friction press or the moulding of the poly-material of horizontal forging and upsetting machine, pier is slightly to the spline size; 3. flange section base: with friction press or the poly-material of horizontal forging and upsetting machine base, heating raw materials other end blank flange to 1200 ℃ for the second time carries out first time of pier flange blank in advance after the secondary local heat; 4. flange section moulding: with the moulding of the poly-material of friction press or horizontal forging and upsetting machine, add pyrogen material flange blank to 1200 ℃ for the third time after three local heat, pier goes out ring flange.In the above-mentioned process, forge because flange Duan Sanci is repeated heating, its temperature is in the sometimes hot and sometimes cold change procedure, is easy to generate forge crack, causes the inherent quality, torsional fatigue life of workpiece, the quiet performance parameter such as intensity of turning round to descend.And because flange section secondary forges the new heating and upsetting equipment of needs one cover, so also exist the big shortcoming of power consumption.
Summary of the invention
At the deficiency that prior art exists, technical problem to be solved by this invention is, a kind of manufacturing process of flanged dish semiaxis is provided, and improves the inherent quality of workpiece, strengthens service life, solves problems such as power consumption is big.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is that a kind of manufacturing process of flanged dish semiaxis comprises the following steps:
(1) raw material: moulded steel that the same half shafts portion of intercepting certain-length etc. are thick or continuous casting steel are as raw material;
(2) poly-material of spline segment and base: raw material one end, as the blank spline, through local heat is after 1150-1200 ℃ for the first time, with friction press or the moulding of the poly-material of horizontal forging and upsetting machine, pier is slightly to the spline size;
(3) flange section base: with friction press or the poly-material of horizontal forging and upsetting machine base, the heating raw materials other end (blank flange) carries out the pre-pier flange blank first time to 1150-1200 ℃ for the second time after the secondary local heat;
(4) flange section moulding: the surplus temperature behind the pre-pier flange blank is directly rolled over out ring flange to the flange blank pendulum at 950-1050 ℃ without heating on rotary forging press.
The manufacturing process of the flanged dish semiaxis of the present invention, after the flange section heats pre-pier and goes out flange blank, utilize surplus temperature directly to put and roll over the moulding ring flange, not carrying out post bake forges, reduced the possibility that forge crack produces, reach the purpose that improves workpiece quality, replaced heating and jumping-up equipment with pendulum rolling equipment simultaneously, reduced power consumption.
Description of drawings
The present invention is described in more detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the raw-material schematic diagram of the first step of the present invention;
Fig. 2 is the schematic diagram of the present invention's poly-material of second step spline segment and base;
The schematic diagram of the blue section of Fig. 3 the present invention three-step approach base;
The schematic diagram of the blue section of Fig. 4 the present invention four step rule moulding.
The specific embodiment
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, automobile of the present invention comprise the following steps: 1. raw materials with the manufacturing process of flanged dish semiaxis: the intercepting certain-length, with thick moulded steel such as half shafts portion or continuous casting steel as raw material;
2. spline segment is poly-expects and base: raw material one end, and as the blank spline, through local heat is after 1150-1200 ℃ for the first time, with friction press or the moulding of the poly-material of horizontal forging and upsetting machine, pier is slightly to the spline size;
3. flange section base: with friction press or the poly-material of horizontal forging and upsetting machine base, the heating raw materials other end (blank flange) is to 1150-1200 ℃ for the second time after the secondary local heat, carries out first time of pier flange blank in advance;
4. flange section moulding: the surplus temperature behind the pre-pier flange blank is directly rolled over out ring flange to the flange blank pendulum at 950-1050 ℃ without heating on rotary forging press.
Certainly, above-mentioned explanation is not to be restriction to invention, the present invention also be not limited to above-mentioned for example, those skilled in the art, in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
