Description
Technical Field
[0001] The utility model relates to the technical field of straightening devices, in particular to a roller assembly straightening device. Background Art
[0002] Rollers are cylindrical or conical working parts, usually made of various metal materials. They are often used in transportation, transmission, support, and guidance. In order to deal with the deformation of metal materials during processing, rollers often need to be straightened by straightening machines during the roller production process.
[0003] In the process of straightening the roller using the straightening device, a pressure head is usually used to straighten the roller. After starting the equipment, the pressure head is slowly moved toward the roller and pressure is gradually applied so as to change the curved shape of the roller. Under the action of pressure, the shape of the roller will gradually change and become more straight. In the process of straightening the roller, unnecessary friction and heat will be generated. When the temperature is high, the performance and accuracy of the pressure head may be affected. Moreover, if the lubrication is insufficient, the high friction may cause premature damage to the pressure head. Although lubricating oil can be continuously added through external equipment during the process, this method will not only increase maintenance costs, but also cause a large amount of waste of lubricating oil. Moreover, if the pressure on the pressure head exceeds its design limit, it may cause damage or failure. How to invent a roller assembly straightening device to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content
[0004] In order to make up for the above shortcomings, the utility model provides a roller assembly straightening device, which aims to improve the problem that the addition of traditional lubricating oil not only increases maintenance costs, but also causes a large amount of waste of lubricating oil, and if the pressure borne by the pressure head exceeds its design limit, it may cause damage or failure.
[0005] The utility model is achieved in this way:

[0007] Preferably, the upper end of the straightening machine bracket is fixedly connected to the mounting plate by bolts, and two slide rails on both sides of the symmetrical upper side wall of the mounting plate are fixedly connected by bolts, and the slide rails are slidably connected to the movable plate and the adjusting bottom plate.
[0008] By adopting the above technical solution, the relative positions of the two movable plates can be adjusted to adjust according to rollers of different lengths. At the same time, the adjustment base plate can be moved to correct different positions of the rollers, thereby increasing the practicality of the device.
[0009] Preferably, the upper end of the adjustment base plate is fixedly connected to the support frame plate, the upper wall of the support frame plate is fixedly connected to the placement box, one end of the upper side wall of the placement box is fixedly connected to the motor, and the output end of the motor passes through the side wall of the placement box and is fixedly connected to the driving gear.
[0010] Preferably, a through hole is provided on one side of the placement box connected to the support frame plate, and a mounting groove is provided on the inner wall relative to the corresponding position of the through hole. The inner wall of the mounting groove is rotatably connected to the two ends of the internal threaded sleeve, the outer wall of the internal threaded sleeve is fixedly connected to the driven gear plate, the driven gear plate is meshingly connected to the driving gear, and the side wall of the placement box at the opening of the through hole is fixedly connected to the limit block.
[0011] Preferably, the outer wall of the screw rod is provided with a limit groove cooperating with the limit block, the outer wall of the screw rod is threadedly connected to the inner wall of the internal threaded sleeve, the inner diameter of the internal threaded sleeve is smaller than the inner diameter of the through hole, and one end of the screw rod passes through the through hole and is fixedly connected to the front end pressure head.
[0012] By adopting the above technical solution, the motor can be started to rotate the driving gear, and then the internal threaded sleeve is driven to rotate through the engagement of the driving gear and the driven gear plate. Further, through the threaded connection between the internal threaded sleeve and the screw rod and the limited sliding of the limit block and the limit groove, the screw rod can achieve the effect of moving up and down, thereby adjusting the height of the front end pressure head and the straightening pressure head.
[0013] Preferably, the lower side wall of the front end pressure head is provided with a docking groove adapted to the docking head, and the front end pressure head is fixedly connected to the pressure sensor on one side of the docking groove.
[0014] Preferably, the upper end of the straightening pressure head is symmetrically fixedly connected to the fixing seat on both sides, the fixing seat is located on the inner side of the pressure spring, the two ends of the pressure spring are respectively fixedly connected to the side wall of the straightening pressure head and the inner wall of the groove opened at the lower end of the docking joint, and the straightening pressure head is fixedly connected with an extrusion block on the side wall of one side of the docking joint.
[0015] By adopting the above technical solution, when the front pressure head and the straightening pressure head are working normally, the pressure spring will shrink appropriately to ensure that the straightening pressure head straightens the roller. When the screw rod moves down more, the pressure between the straightening pressure head and the roller is relatively large, and at this time the pressure spring shrinks more. When the extrusion block contacts the pressure sensor, the pressure sensor is triggered to send a signal, causing the motor to stop working or reverse to drive the straightening pressure head to rise, so as to avoid the pressure on the pressure head exceeding its design limit due to high pressure, thereby causing it to be damaged or fail.
[0016] The beneficial effects of the utility model are:
[0017] During normal operation, the pressure spring will shrink appropriately, and the cooperation between the fixed seat and the groove will ensure the stability of the straightening pressure head during processing, thereby ensuring the straightening of the roller by the straightening pressure head. When the screw moves down more, the pressure between the straightening pressure head and the roller will be greater. At this time, the pressure spring shrinks more, causing the extrusion block to squeeze the pressure sensor, which triggers the pressure sensor to send a signal. The pressure sensor is connected to the motor electrical signal, and the signal can be fed back to the motor, causing the motor to stop working or reverse to drive the straightening pressure head to rise, so as to avoid the pressure on the straightening pressure head exceeding its design limit when the pressure is high, thereby causing it to be damaged or fail.
[0018] Part of the heat generated during the operation of the straightening pressure head can be absorbed by the lubricating oil. When the temperature inside the oil storage chamber gradually increases, the lubricating oil can expand and be discharged from the oil drip hole, thereby achieving lubrication of the straightening pressure head, reducing the wear and friction of the straightening pressure head, increasing the service life of the straightening pressure head, reducing costs and reducing waste.
