Detailed Description

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings, which are not to be construed as limiting the scope of the utility model.

As shown in fig. 1-3, the plastic wave reducer with adjustable on-line operation of the metal corrugated pipe comprises a machine base 1. The machine base 1 is used for providing support for other parts. In use, the housing 1 may be fixed or placed on the floor of a production plant.

A hollow shaft 2 is installed at the center of the housing 1 such that the hollow shaft 2 can rotate with respect to the housing 1. The hollow shaft 2 is provided with a driving belt wheel 3, a roller adjusting disc 11, a thrust ball bearing 4, a wedge action disc 5 and a machine head 7.

Wherein, the driving belt wheel 3 is arranged on the right side of the machine base 1. The machine base 1 is also provided with a motor which is not shown in the figure. The output shaft of the motor can rotate with the driving belt wheel 3 through a driving belt. Thereby, the hollow shaft 2 can be driven to rotate by the driving belt wheel 3 under the driving of the motor.

The roller adjusting disc 11, the thrust ball bearing 4, the wedge action disc 5 and the machine head 7 are arranged on the left side of the machine base 1 from right to left at a time. Wherein the roller adjusting disk 11, the thrust ball bearing 4 and the wedge action disk 5 can move left and right on the hollow shaft 2. The nose 7 is fixedly arranged on the hollow shaft 2.

Three lead screws 12 are arranged on the machine base 1. The screw 12 can rotate relative to the housing 1. And, three lead screws 12 are uniformly distributed on the machine base 1 along the circumference.

Each screw 12 is provided with a sprocket 13 and the roller adjusting disk 11 is mounted on the three screws 12 by three nuts. The rotation of the sprocket 13 can thereby drive the spindle 12 to rotate, and the rotation of the spindle 12 can drive the roller adjustment disk 11 to move left and right on the hollow shaft 2 via the nut.

Preferably, the base 1 is further provided with a servo motor 15. The servo motor 15 is used for driving the sprocket 13 to rotate.

More preferably, the servo motor 15 rotates a pulley coaxial with one of the sprockets 13 via a belt 16. The three sprockets 13 are connected by a chain 17. Therefore, three chain wheels can be driven to synchronously rotate through one servo motor, so that the left-right movement adjustment of the roller adjusting disc 11 is realized.

In the utility model, three wedges 6 are arranged in the wedge action disc 5 and the machine head 7, and three sliding blocks 8 respectively propped against the three wedges 6 are arranged in the machine head 7.

Thus, when the roller adjusting disk 11 moves leftwards, the thrust ball bearing 4 is pushed to move leftwards, and the cam action disk 5 is pushed to move leftwards by the thrust ball bearing 4. When the wedge action disc 5 moves leftwards, the wedge 6 is pushed to move leftwards. Movement of the cam 6 to the left will push the slider 5 to the left.

Meanwhile, in the utility model, three shaping rollers 9 respectively propped against the sliding block 8 are also arranged on the machine head 7.

Preferably, three mounting blocks 18 respectively abutting against the three sliding blocks 8 are mounted on the machine head 7. The mounting blocks 18 are movably mounted on the handpiece 7 and one of the truing rollers 9 is mounted on each of the mounting blocks 18.

Wherein, the sliding block 8 is abutted with the mounting block 18 through an inclined plane. Therefore, when the sliding block 8 moves leftwards, the mounting block 18 is promoted to shrink inwards in the radial direction, so that the space between the three shaping rollers 9 is reduced, and the purposes of adjusting the inner and outer diameter sizes and the peak heights of the workpiece without stopping the machine can be realized.

In the present utility model, each of the truing rollers 9 is preferably mounted on the mounting block 18 by a bolt 20.

More preferably, the handpiece 7 is further provided with a synchronizer 10. The three truing rollers 9 are each mounted on the synchronizer 10 by a bearing 19 so that the three truing rollers 9 are synchronously rotated.

Finally, the driving pulley 3 and the chain wheel 13 are preferably sleeved with a protective cover 14 to ensure safety.

When the metal corrugated pipe online operation adjustable wave shaping and shrinking machine is used for shaping and shrinking the metal corrugated pipe, the motor drives the driving belt wheel 3 to rotate. The rotation of the transmission drive 3 drives the machine head 7 to rotate. And the three shaping rollers 9 are driven to rotate by the rotation of the machine head 7, so that the shaping wave shrinkage of the metal corrugated pipe is realized by the three shaping rollers 9.

When the metal bellows with different wave shrinking sizes need to be shaped, for example, when the metal bellows with smaller wave shrinking diameter needs to be shaped, the servo motor 15 drives the sprocket 12 to rotate positively. Rotation of the sprocket 12 will drive the roller adjustment plate 11 to move to the left. When the roller adjusting disc 11 moves leftwards, the thrust ball bearing 4 is pushed to move leftwards, and the wedge action disc 5 is pushed to move leftwards through the thrust ball bearing 4. When the wedge action disc 5 moves leftwards, the wedge 6 is pushed to move leftwards. The movement of the cam 6 will push the slider 8 to move to the left. Since the sliding block 8 is abutted against the mounting block 18 through an inclined plane. Therefore, when the sliding block 8 moves leftwards, the elastic force of the radial spring in the mounting block 18 is overcome, the mounting block 18 is promoted to shrink inwards in the radial direction, and therefore the space between the three shaping rollers 9 is reduced, and the metal corrugated pipe with small diameter for shaping and shrinking without stopping can be realized.

When the metal corrugated pipe with the larger diameter is required to be shaped, the sprocket 12 is driven to reversely rotate by the servo motor 15. Rotation of the sprocket 12 will drive the roller adjustment plate 11 to move to the right. The roller adjusting disc 11 will not push the thrust ball bearing 4 after moving rightward, the thrust ball bearing 4 will not push the cam action disc 5, the cam action disc 5 will not push the cam 6, and the cam 6 will not push the slider 8, so that the slider 8 can move rightward. Since the sliding block 8 is abutted against the mounting block 18 through an inclined plane. Therefore, when the sliding block 8 moves from the first direction to the second direction, the elastic force of the radial springs in the mounting block 18 expands radially outwards, so that the distance between the three shaping rollers 9 is increased, and the metal corrugated pipe with large diameter for shaping and shrinking without stopping can be realized.

The shaping wave shrinking machine with the adjustable online running of the metal corrugated pipe can adjust the spacing of the shaping rollers online under the condition of no shutdown, thereby achieving the purpose of adjusting the inner and outer diameter sizes and the peak heights of the workpieces without shutdown. And the problem that the traditional metal corrugated pipe shaping wave shrinking machine can be adjusted only by stopping the machine is solved, and the working condition flow of automation and semi-automation can be further realized, so that the yield and the yield can be improved, and the production cost can be reduced.

The above examples of the present utility model are merely illustrative of the present utility model and are not intended to limit the embodiments of the present utility model. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. Not all embodiments are exhaustive. All obvious changes or modifications which come within the spirit of the utility model are desired to be protected.
