Abstract

Embryo material preparation process among a kind of C-shaped cross section ring provided by the invention, Alloy ingot is selected to obtain workpiece by forging, the present invention using ring rolls by will first prepare intermediate embryo material, the tonnage demand of cerclage machine equipment is reduced, and the workpiece yield strength after production can reach 350Mpa or more.

Description

A kind of C-shaped cross section ring centre embryo material preparation process
Technical field
The present invention relates to embryo material preparation processes among a kind of C-shaped cross section ring.
Background technique
C-shaped cross section forging is the critical component of certain equipment, as shown in Figure 1, due in irregular shape, and many places are that abnormity is bent Face, there are biggish difficulty for forging.Section is more complicated, and protrusion part and recess are deep, using regular rectangular shape section When ring billet shapes, blank and core roller mould contact surface knot are excessive, relatively high to the requirement of looping mill equipment tonnage, will cause looping mill rolling mistake Journey is difficult to carry out.
Summary of the invention
In order to solve the above technical problems, the present invention provides embryo material preparation processes among a kind of C-shaped cross section ring.
The present invention is achieved by the following technical programs.
Embryo material preparation process among a kind of C-shaped cross section ring provided by the invention, selects Alloy ingot by forging It the steps include: to workpiece
1. alloy pig is heated to 1150~1180 DEG C;
2. by alloy pig jumping-up to the 2/5~3/5 of former height;
3. the embryo material after jumping-up to be punched out to diameter+95~105mm of rear reaming to ring rolls;
4. size needed for carrying out rolling ring to workpiece with ring rolls, deflection is 40%~50%;
5. being air-cooled to room temperature.
2. middle whole deformation temperature is controlled at 950~1000 DEG C the step.
The step 3. used in punch diameter be 250mm.
4. middle whole deformation temperature is controlled at 800~850 DEG C the step.
The step is 2. middle to carry out jumping-up to alloy pig using hydraulic press.
The concrete operations that blank places it on ring rolls are to cover core roller bushing on core roller, start ring rolls, in master Roll is rotated with the speed of 1.2m/s, and core roller is moved in a straight line with the speed of 0.8mm/s~1.2mm/s to home roll direction, cone roller It is pressed on blank end face, blank starts turning under the drive of king roller and core roller bushing and core roller.With core roller bushing and core Roller is moved in a straight line to king roller, and blank diameter is constantly grown up, and wall thickness is gradually reduced, and is highly kept not under the action of cone roller Become.Size in place after, close ring rolls, blank among the C font ring after obtaining rolling ring
The beneficial effects of the present invention are: by will first prepare intermediate embryo material using ring rolls, reduce cerclage machine equipment Tonnage demand, and make after workpiece yield strength can reach 350Mpa or more.
Detailed description of the invention

Fig. 2 is rolling ring machining structural schematic diagram of the invention;
Fig. 3 is intermediate embryo material structural schematic diagram of the invention;
In figure: 1- king roller, 2- core roller set, 3- core roller, 4- cone roller, 6- embryo material.
Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
Roll the rolloff forming manufacturing method for adding finish to gauge to combine in advance using ring rolls.Product cross section is that irregular abnormity is cut Face, ring wall thickness reach 650mm, material complex flow during ring rolling.It is prefabricated therefore, it is necessary to be carried out to blank, due to Forging section is substantially relatively uniform everywhere and is less than the Wall-Thickness Difference of internal-and external diameter, it is contemplated that deep, utilization is protruded and be recessed to ring The intermediate base of plastic deformation progress is prefabricated to still have biggish frictional force.The it is proposed of the invention first produces a height Degree is higher, and the relatively thin ring of wall thickness pre-allocates material, and material is distributed at ring both ends, a shape is produced and connects Blank when the C-shaped forging of nearly final forging is as finish to gauge, stretches the principle of drawing, by finish to gauge when deforming using material plasticity Obtain final looping mill rolling part.
Embodiment 1
In the present embodiment, a kind of C-shaped cross section ring centre embryo material preparation process selects Alloy ingot to obtain by forging Workpiece the steps include:
1. alloy pig is heated to 1160 DEG C;
2. alloy pig jumping-up is to the 2/5 of former height;
3. the embryo material after jumping-up is punched out the diameter+95mm of rear reaming to ring rolls;
4. size needed for carrying out rolling ring to workpiece with ring rolls, deflection 42%;
5. being cooled to room temperature.
It stretches when the intermediate embryo material produced by using above-mentioned technique using material plasticity by being deformed and finally forges Ring forging, yield strength reaches 361MPa, and the Charpy-type test of V-notch is done at -20 DEG C, ballistic work it is flat Mean value is 125J.
Embodiment 2
A kind of C-shaped cross section ring centre embryo material preparation process, selects Alloy ingot to obtain its step of workpiece by forging Are as follows:
1. alloy pig is heated to 1170 DEG C;
2. alloy pig jumping-up is to the 1/2 of former height;
3. the embryo material after jumping-up is punched out the diameter+100mm of rear reaming to ring rolls;
Size needed for 4. ring rolls carries out rolling ring to workpiece, deflection 48%;
5. being air-cooled to room temperature.
It stretches when the intermediate embryo material produced by using above-mentioned technique using material plasticity by being deformed and finally forges Ring forging, yield strength reaches 364MPa, and the Charpy-type test of V-notch is done at -20 DEG C, ballistic work it is flat Mean value is 170J.
