Description

Technical Field

[0001] The utility model relates to the technical field of straightening equipment, in particular to a straightening machine for main roller production. Background Art

[0002] The roller is a rotating cylindrical structure that is installed in many current production machines. The roller can be used to transport, press, stretch and limit the target object. It is an important component of current production machinery. To ensure that it can operate the target object smoothly and stably, it is necessary to ensure that the level of the roller itself is in a vertical state. Any slight bending will affect production.

[0003] Nowadays, the curved parts are basically corrected by hydraulic pressure through a straightening machine to reduce the curvature of the roller. However, the curvature detection of the straightening machine is basically through electronic sensing. This method is accurate but relatively simple and easily affected by external factors. Therefore, a straightening machine for main roller production is proposed here. Utility Model Content

One end of the spring is fixedly connected to the support plate, and the output end of the telescopic rod passes through the support plate and is inserted in the middle of the spring.

One end of the sliding groove is detachably connected to a door frame, and the top of the door frame and the side wall opposite to the support plate are detachably connected to a hydraulic cylinder, and the output end of the hydraulic cylinder is detachably connected to a pressing plate.

[0009] The utility model has the following advantages: on the basis of the original curvature detection, additional side columns and a center column are installed, and the side columns and the center column are driven to rise and fall by springs. When there is a bend, the extended lengths of the side columns on both sides are the same, while the extended length of the middle center column is the longest.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Please refer to Figure 1-3The utility model relates to a straightening machine for main roller production, comprising a base 1, the top side walls of the base 1 are evenly and detachably connected to a support plate 2, the top side walls of the support plate 2 near both ends are telescopically and movably connected to side columns 3, a center column 4 is set between the two side columns 3, and the center column 4 is telescopically and movably connected to the middle of the top side walls of the support plate 2, the tops of the side columns 3 and the center column 4 are rotatably connected to a movable arc plate 5, three bottom columns 11 are set up in the support plate 2, the side columns 3 and the center column 4 are telescopically and movably connected in the bottom column 11, a spring 15 is connected in the bottom column 11, one end of the center column 4 and the side column 3 located in the bottom column 11 is fixedly connected to the top of the spring 15, and a position sensor is embedded in the inner wall of the bottom column 11;

[0016] Two connecting columns 12 are fixedly connected to the top side wall inside the support plate 2 and near the middle. The bottom end of the connecting column 12 is fixedly connected to the bearing plate 13. The bottom column 11 located in the middle is detachably connected to the bearing plate 13. The bottom side wall inside the bottom column 11 is detachably connected to the telescopic rod 17. The side wall above the telescopic rod 17 inside the base 1 is fixedly connected to a support plate 16. The support plate 16 is a ring structure. One end of the spring 15 is fixedly connected to the support plate 16. The output end of the telescopic rod 17 passes through the support plate 16 and is inserted in the middle of the spring 15.

[0017] The technical effect of this solution is: the roller is driven to rotate by a driving device, and is detected as it rotates. When there is a bending position, the side columns 3 and the center column 4 will rise. Because the roller is a cylindrical structure, the side columns 3 on both sides will rest against the two sides of the bottom of the roller, so that the two side columns 3 can be at the same height, and the center column 4 is in the position with the greatest bending, which will make it extend the longest. The height difference between the side columns 3 and the center column 4 is obtained by the position sensor, and the bending position is obtained. In conjunction with the traditional detection method, the positioning accuracy is improved, and the staff can also observe the bending position with the naked eye by observing the changes in the side columns 3 and the center column 4, which is convenient for manual adjustment of the position of the pressing plate 10 to ensure the accuracy of the straightening.

[0018] The side wall near the bottom end of the support plate 2 is rotatably connected with a screw rod 6, the screw rod 6 is a bidirectional thread structure, and both ends are threadedly sleeved with a moving block 14, the moving block 14 is detachably connected to the bottom end of the two bottom columns 11, and the side walls on both sides of the base 1 are provided with a slide groove 7, and the slide groove 7 is slidably connected to the slide groove 7, one end of the slide groove 7 is detachably connected to the door frame 8, the top of the door frame 8 and the side wall opposite to the support plate 2 is detachably connected to the hydraulic cylinder 9, and the output end of the hydraulic cylinder 9 is detachably connected to the pressing plate 10.

[0019] The technical effect of this solution is: when necessary, the screw 6 can be rotated to drive the two movable blocks 14 to move through the principle of threaded connection, so as to adjust the distance between the two side columns 3 to adapt to rollers of different sizes. By setting up a movable arc plate 5, the roller can be provided with stable support to ensure stability, while ensuring the tightness of the fit with the roller.

[0020] Specifically, when the present invention is used, the roller to be inspected is placed on the equipment, and then it is driven to rotate. As it rotates and bends, it will also rotate. At this time, the side columns 3 and the center column 4 will be raised and lowered under the drive of the spring 15. When the two side columns 3 extend to the same length and the center column 4 extends to a greater length than the side columns 3, the bending position can be determined. In combination with the traditional detection method, the accuracy of the detection can be improved. The door frame 8 is then moved along the slide 7 to the specified position, and then the hydraulic cylinder 9 is started to drive the pressing plate 10 to press the bending position, thereby performing a straightening operation. When straightening, it is necessary to provide fulcrums on both sides of the bending position. At this time, the telescopic rod 17 is started to hold the side columns 3 immovable, so that a fulcrum can be provided for the roller. After straightening, the telescopic rod 17 is retracted to make the side columns 3 lose their limit to ensure normal operation. According to the size of the roller, the screw 6 is turned in advance to move the two bottom columns 11 to the appropriate position to provide stable support for the roller.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
