Abstract

A kind of multi-point radial milling ring technological process that is used for moulding than the annular workpieces of compound section shape.It utilizes the ring radial dimension to enlarge not the bigger characteristics of relative rigidity for a long time, carries out radial loop in ring periphery many places and is rolled to the section moulding.Solved spreading than smaller situation under, the moulding problem of the ring that complexity or cross section deformation are big.Enlarged general rolling ring (reaming) machine and ring and rolled over the range of application of technology, proposed the working principle of design of novel Ring Rolling Machine, this technology can be widely used in the manufacturing of series products such as crawler type thrust wheel, holder sprocket wheel.

Description

The present invention a kind ofly is used to be shaped than the milling ring technological process of the annular workpieces of compound section shape.
Known milling ring technological process also claims reaming, when spreading, because the growth rate of annular workpieces radial dimension is much larger than complicated or be out of shape the forming speed of big section, so spreading than (promptly roll over to expand back forging internal diameter and roll over expand before the ratio of blank internal diameter) under smaller situation, have little time to be full of the bigger die cavity of cross section deformation, the radial dimension of ring has expanded limit to.Therefore, it can only be applicable to that section configuration simple or spreading is than big or through giving the annular element that forging has been shaped substantially.This has just limited the range of application of ring rolling technology.
Task of the present invention just provide a kind of spreading than smaller situation under, the simple blank of section configuration directly rolled over expands the process that to have than the annular workpieces of compound section shape.
Feature of the present invention utilizes the ring radial dimension to change when little exactly, the ring wall thickness is thicker, the characteristics that relative rigidity is bigger, radially exert pressure in ring periphery many places, thereby the restriction annular workpieces radially freely enlarges, force annular workpieces top layer metal that the lateral flow that bigger being intended to is full of die cavity takes place, the complicated annular workpieces of section is shaped.Thereby enlarged the range of application that Ring Rolling Machine and ring are rolled over technology, caused the manufacturing process of a series products (as the caterpillar thrust wheel etc.) and the change of structural design, produced significant technical economic benefit.
The point radial loop is rolled over technology more than utilization the present invention, can optimize the structural design and the production technology of series products such as caterpillar thrust wheel greatly.By shown in Figure 6,9. and 10. can at first use process of the present invention to roll over to expand the thrust wheel wheel rim, 8. the center that the wheel rim that processes 9. and is 10. made with a seamless steel pipe constitutes the thrust wheel of modular construction with interference fit then.It (is about to two forged steel blanks one that 6. and 7. is welded in the centre, as shown in Figure 5 with at present current in the world Japanese Xiao Song technology after processing.) compare, have following tangible advantage:
A, its available two kinds of unlike material are combined into thrust wheel, and are tough outer hard in realizing, adapt to the job requirement of thrust wheel better.
The material of B, thrust wheel is generally 55SiMn, and solderability is poor, and this technology has been cancelled welding procedure, has avoided this unfavorable factor, has improved its bulk strength.
C, improved the thrust wheel working surface and inner metallic fiber flows to, this has not only improved the material capability of surface of the work, and has strengthened the ability of the terminal stress corrosion resistant of streamline.
D, blank accuracy of manufacture height, blank section are more near the shape of finished product.This has not only reduced raw-material consumption, and has significantly reduced the machining expense.
E, can realize the recovery of this kind wheel, backing off wears away the wheel rim of limit, and center still can reuse once more.
Feature of the present invention will be illustrated more clearly in from the accompanying drawing of following enforcement.
Fig. 1. the multi-point radial ring is rolled over fundamental diagram.
Fig. 2. along the profile part of the A-A line among Fig. 1.
Fig. 3. the deformation pattern when ring is subjected to radially spreading in many places.

Milling ring technological process shown in Figure 1, be that 1. the annular blank that heating-up temperature is moderate is enclosed within the core roller and 4. goes up, move radially main roll milling wheel 3. or the core roller 4., the main roll milling wheel of rotation is after 3. 1. base contact with ring, driving the ring base 4. 1. rotates with the core roller, under the continuous action of pressure p, continuous distortion takes place in ring base top layer metal 1., after ring base interior external diameter 1. has expansion slightly, 5. annular workpieces 1. outer surface successively contacts with regard to 2. reaching right roll milling wheel with driven left roll milling wheel, after this, under the continuation effect of pressure p, 2. 5. right roll milling wheel gone up with left roll milling wheel and produced reaction force R1 and R2 respectively, like this, p, the ring that R1 and R2 act on rotation simultaneously is 1. on the outer surface, having formed the multi-point radial ring rolles over, it has limited freely enlarging of ring radial dimension, force ring top layer metal 1. that the lateral flow (as shown in Figure 2) that bigger being intended to is full of the race die cavity takes place, at this moment, because of the ring endoporus still has expansion slightly, on the motionless Ring Rolling Machine of core roller, the ring inner surface breaks away from and the contacting of core roller, and the core roller does not just participate in spreading.The ring that relative rigidity is enough is regarded as moulding-rigid body, and the local deformation on stressed surface makes section progressively be shaped.For the thicker ring of forging wall thickness, when ring top layer metal was full of die cavity fully, the spreading process just came to an end.To the thin-walled ring, can be with so far ring forming process as the phase I.Second stage is removed to control workpiece outside dimension position to movable left roll milling wheel, continue again by main roll milling wheel 3. or the core roller 4. workpiece is exerted pressure, by common rolling expansion process 1. ring is rolled over the thin and hole enlargement size (as shown in Figure 4) to requirement.Among Fig. 1 and Fig. 4, M is a ring rolling work moment, and Fi is that the contact position acts on the frictional force on the working surface, and Ni is the direction of rotation of each part among the figure.Fig. 3. shown overweening deformation state when 1. ring is subjected to radially spreading in many places.
Utilize milling ring technological process method of the present invention, also can design several novel Ring Rolling Machines.Each roll milling wheel of this Ring Rolling Machine 2., 3. and 5., as shown in Figure 1 and Figure 4, be respectively the smooth rotary body of same bus, in the spreading process, each roll milling wheel 2., 3. and 5. central axis and the core roller 4., ring central axis 1. is parallel to each other.
