Abstract

The invention discloses a kind of ring rolling method, it is applied to the finished product ring with the ratio of thickness less than 2 for the pre-rolling height, the method includes:After blank heating, carry out forging punching and Mechanical Processing Center hole, to obtain just shape ring part, and make the described just height of shape ring part and the Ratio control of thickness in the range of 0.5 1;Described just shape ring part is rolled, to obtain semi-finished product ring;Remove allowance, allowance is removed to described semi-finished product ring, obtain finished product ring.By validation trial, above-mentioned ring rolling method avoids height and cannot roll and the defect such as wave.

Description

A kind of ring rolling method

Technical field

The present invention relates to blank rolling technical field, more particularly, to a kind of ring rolling method.

Background technology

Also known as ring rolling or reaming, it is made by ring rolling equipment machine for rolling ring (also known as ring rolling machine to ring rolling Or staving press) make ring produce wall thickness reduction, enlarged-diameter, the plastic working technique of cross section profile shaping.

For machine for rolling ring, especially 5 meters machine for rolling ring, generally radially roll-force is more than axial rolling force.Therefore in pre-rolling When being highly less than 2 finished product ring with the ratio of thickness, easily the phenomenon of unstability in machine for rolling ring, and then leads to height cannot roll To target size, and easily cause ring the major defects such as wave occur.

In sum, how to solve machine for rolling ring when the ratio of pre-rolling height and thickness is less than 2 finished product ring, ring Defect and the problem that cannot roll easily there is, it has also become those skilled in the art's technical barrier urgently to be resolved hurrily.

Content of the invention

It is an object of the invention to provide a kind of ring rolling method, to solve the ratio in pre-rolling height and thickness for the machine for rolling ring When value is less than 2 finished product ring, easily defect and the problem that cannot roll in ring.

To achieve these goals, the invention provides a kind of ring rolling method, it is applied to pre-rolling height and thickness Ratio be less than 2 finished product ring, the method comprising the steps of:

After blank heating, carry out forging punching and Mechanical Processing Center hole, to obtain just shape ring part, and make described just shape ring The height of part and the Ratio control of thickness are in the range of 0.5-1;

Described just shape ring part is rolled, to obtain semi-finished product ring;

Remove allowance, allowance is removed to described semi-finished product ring, obtain finished product ring.

Preferably, described removal allowance is to remove corresponding surplus by cutting edge and deburring.

Introduce content compared to background technology, above-mentioned ring rolling method, machine for rolling ring is in the ratio of pre-rolling height and thickness During the finished product ring less than 2 for the value, by the first height of shape ring part and the Ratio control of thickness that are processed into blank in 0.5-1 model Enclose interior so that when first shape ring part is rolled, with radial rolling for main force direction, the rolling force of short transverse is relatively Reduce, by validation trial, above-mentioned ring rolling method avoids height and cannot roll and the defect such as wave.

Brief description

In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing Have technology description in required use accompanying drawing be briefly described it should be apparent that, drawings in the following description be only this Inventive embodiment, for those of ordinary skill in the art, on the premise of not paying creative work, can also basis The accompanying drawing providing obtains other accompanying drawings.

Fig. 1 is a kind of flow chart of ring rolling method provided in an embodiment of the present invention.

Specific embodiment

The core of the present invention is to provide it is an object of the invention to provide a kind of ring rolling method, to solve machine for rolling ring pre- When rolling is highly less than 2 finished product ring with the ratio of thickness, easily defect and the problem that cannot roll in ring.

In order that those skilled in the art more fully understands the technical scheme that the present invention provides, below in conjunction with accompanying drawing and The present invention is described in further detail for specific embodiment.

As shown in figure 1, a kind of ring rolling method provided in an embodiment of the present invention, it is applied to pre-rolling height and thickness The ring that ratio is less than 2, the method comprising the steps of:

Step 001:After blank heating, carry out forging punching and Mechanical Processing Center hole, to obtain just shape ring part, and make this Just the height of shape ring part and the Ratio control of thickness are in the range of 0.5-1;

Step 002:This first shape ring part is rolled, to obtain semi-finished product ring;

Step 003:Remove allowance, allowance is removed to semi-finished product ring, obtains finished product ring.

Introduce content compared to background technology, above-mentioned ring rolling method, machine for rolling ring is in the ratio of pre-rolling height and thickness During the finished product ring less than 2 for the value, by the first height of shape ring part and the Ratio control of thickness that are processed into blank in 0.5-1 model Enclose interior so that when first shape ring part is rolled, with radial rolling for main force direction, the rolling force of short transverse is relatively Reduce, by validation trial, above-mentioned ring rolling method avoids height and cannot roll and the defect such as wave.

In particular embodiments, above-mentioned removal allowance can be corresponding remaining by cutting edge and deburring removal Amount.Of course, it should be understood that above-mentioned is only for the citing removing allowance, can also be that those skilled in the art are normal Other remove the operation involved by allowance.

Above ring rolling method provided by the present invention is described in detail.It should be noted that this specification In each embodiment all described by the way of going forward one by one, what each embodiment stressed is different from other embodiment Part, between each embodiment identical similar partly mutually referring to.

Also, it should be noted herein, such as first and second or the like relational terms are used merely to one Entity or operation are made a distinction with another entity or operation, and not necessarily require or imply between these entities or operation There is any this actual relation or order.And, term " inclusion ", "comprising" or its any other variant are intended to contain The comprising of lid nonexcludability, so that including a series of article of key elements or equipment not only includes those key elements, but also Including other key elements being not expressly set out, or also include for this article or the intrinsic key element of equipment.Do not having More limit in the case of, the key element that limited by sentence "including a ..." is it is not excluded that in the article including above-mentioned key element Or also there is other identical element in equipment.

Specific case used herein is set forth to the principle of the present invention and embodiment, the saying of above example Bright it is only intended to help and understands the method for the present invention and its core concept.It should be pointed out that the ordinary skill for the art For personnel, under the premise without departing from the principles of the invention, the present invention can also be carried out with some improvement and modify, these improvement Also fall in the protection domain of the claims in the present invention with modifying.
