Abstract
The present invention relates to a method used for making a corrugated pipe by rolling circular grooves on a circular cylinder with larger diameter and a device applying the method. A main roller arranged on the main roller comprises the whole ripples of a workpiece, and a movable roller mould arranged on a movable roller comprises a ripple. The length of a used supporting roller exceeds that of the workpiece, and the rolling process is finished by moving the movable roller to roll the ripples one by one or rolling the ripples pair by pair from the middle to both of the two ends of the workpiece. Additionally, the round correction of the workpiece is carried out by the combined action of the main roller, the movable roller and the supporting roller while the rolling. When the present invention is used for rolling the corrugated pipe, the workpiece does not need to be moved. Thus, the operation is convenient, and the workers' labor intensity is reduced. The round correction is finished during the rolling, and the work efficiency is improved.
Description
The present invention relates to a kind of on than large diameter cylinder the rolling ring-shaped groove with the method for making bellows and the equipment of using this method.
Existing cold conditions rolling is that single ripple is rolling than the method for major diameter bellows, can not be to the workpiece set round, and the operation of rolling needs travelling workpiece, complicated operation, and efficient is low, low precision.
The purpose of this invention is to provide a kind of can cold conditions processing than the method for major diameter bellows and use the equipment of this method, can not need travelling workpiece to the workpiece set round in rolling, simple to operate, the precision height lowers labor strength.
The solution of the present invention is: a kind of method of machining bellows, the home roll mould that difference is arranged on the home roll contains all ripples of workpiece, the movable roller die that is arranged on the movable roll contains a ripple, the backing roll length of using surpasses Workpiece length, the operation of rolling be by mobile movable roll one by one ripple be rolled or by workpiece middle part to two ends by to carrying out, and the acting in conjunction by home roll, movable roll and backing roll is carried out set round to workpiece in rolling.
When carrying out said method, can when rolling, apply axial force to central authorities to workpiece by the workpiece two ends.
The equipment of using said method is: comprise frame, chassis, home roll and backing roll are arranged on the frame, movable roll is linked by feed arrangement and chassis, the length of backing roll surpasses workpiece and has lowering or hoisting gear, the home roll mould is arranged on the home roll and contains whole ripples, and movable roller die is located on the movable roll and is contained a ripple.
Workpiece axial advance or positioner are set on the frame of the said equipment.
Do not need travelling workpiece when adopting the rolling bellows of the present invention, easy and simple to handle, alleviated labor strength, and can in rolling, carry out set round workpiece, improved work efficiency.The home roll mould has the whole ripples of workpiece, can prevent the workpiece axial float, makes bellows-shaped, spacing accurate, also can improve workpiece accuracy and quality.
Fig. 1 is the present device front view.
Fig. 2 is the present device left view.
Equipment comprises frame 1, chassis 5 among the figure, and the home roll 2 and the backing roll 4 that are provided with the home roll mould are arranged on the frame 1, and the movable roll 3 that is provided with movable roller die is linked by feed arrangement 8 and chassis, and backing roll length surpasses workpiece and has lowering or hoisting gear 10.6 is main transmissions among the figure, and 7 for movable roll moves axially guide rail, and 9 is the movable roll bearing block, and 11 are the guiding tie-beam.
Workpiece axial advance or positioner are set on frame, can help workpiece to fill and workpiece centering to the first of material center.
Utilize the present invention before rolling or in the operation of rolling, can on workpiece or mould, be coated with,, can reduce the attenuate amount of workpiece in order to moving of material with lubricant.
Backing roll quantity of the present invention can be two or more, is positioned at outside the workpiece.Each roller all can be done initiatively to rotatablely move, and also can only do initiatively to rotatablely move with home roll, and all the other each rollers are done auxiliary the rotation or passive movement.
When movable roller die is outside workpiece, can on frame, establish the guiding tie-beam, movable roller die moves axially along the guiding tie-beam, and the guiding tie-beam play the guiding role, and the tangential force that roller die is subjected to when bearing rolling simultaneously also guarantees movable roll mold shaft line and home roll mold shaft line parallel.
Claims (6)
1, a kind of corrugated pipe rolling method, the home roll mould that it is characterized in that being arranged on the home roll contains the whole ripples of workpiece, the movable roller die that is arranged on the movable roll contains a ripple, the backing roll length of using surpasses Workpiece length, the operation of rolling be by mobile movable roll one by one ripple be rolled or by workpiece middle part to two ends by to carrying out, and the acting in conjunction by home roll, movable roll and backing roll is carried out set round to workpiece in rolling.
2,, it is characterized in that applying axial force to central authorities to workpiece by the workpiece two ends when rolling by the described corrugated pipe rolling method of claim 1.
