Description

Technical Field

[0001] This utility model relates to the field of tension straightening technology, specifically a high-precision tension straightening machine. Background Technology

[0002] In industrial production, especially in the field of metal processing, materials often become bent or uneven during rolling, transportation or storage, which affects the performance of the materials and the quality of the products. Therefore, straightening machines are needed to improve the shape accuracy of the materials.

[0003] Chinese patent CN214022726U discloses a novel tension straightening machine, comprising a housing, a worm gear, and a push rod. A motor is mounted on the side of the housing, and the output end of the motor passes through the surface of the housing and connects to one end of a drive shaft. The other end of the drive shaft is connected to the inner wall of the housing. The upper surface of the drive shaft is connected to the lower surface of the worm gear, and the middle of the worm gear is fixed to the outer surface of a movable rod. One end of the movable rod passes through the surface of the housing, and the other end of the movable rod is fixed to a fixing block. A pressure rod is embedded in the outer surface of the fixing block, and the middle of the pressure rod is embedded and fixed to the edge of a support block. This novel tension straightening machine uses a round tube workpiece body placed on a first pulley, which supports the workpiece body. The two ends of the workpiece body are aligned with the support block. Then, pressure plates move relative to each other via the pressure rod, facilitating the clamping of the two ends of the workpiece body.

[0004] However, since the position of the first pulley is fixed and cannot be adjusted, the tension straightener can only straighten pipes of a fixed diameter, which has low applicability and versatility. In addition, the pipe surface will generate debris during straightening. The debris will be discharged with the straightened pipe, which will not only pollute the working environment, but also affect the straightening quality of the pipe. Therefore, a high-precision tension straightener is needed. Utility Model Content

[0013] Preferably, guide seats are fixedly installed on the top of both ends of the machine body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) This high-precision tension straightening machine, by rotating the threaded screw with the first handwheel, allows the lifting frame to move up and down within the first straightening frame under the action of the threaded sleeve, thus facilitating the adjustment of the distance between the active straightening roller and the first driven straightening roller. By rotating the bidirectional screw with the second handwheel, the two moving blocks threadedly connected to the bidirectional screw can move towards each other along the slide groove, thus facilitating the adjustment of the distance between the two sets of second driven straightening rollers within the two second straightening frames, thereby realizing tension straightening of pipes of different diameters, effectively improving the applicability and versatility of the device.

[0016] 2) This high-precision tension straightening machine uses a water pump to pump water pre-injected into the water tank through the water injection pipe into the nozzle.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Combination Figures 1-5 A high-precision tension straightening machine includes a machine body 1, a first straightening frame 2, a cleaning tank 4, and two second straightening frames 3. Multiple active straightening rollers 8 are rotatably arranged inside the first straightening frame 2. The multiple active straightening rollers 8 are connected to each other by a belt drive assembly 10. A motor 9 is arranged on the top of the machine body 1 near the first straightening frame 2. The output shaft of the motor 9 is fixedly connected to one of the active straightening rollers 8. Guide seats 5 are fixedly arranged on the top of both ends of the machine body 1. Adjustment mechanisms 6 are arranged on the first straightening frame 2 and the second straightening frame 3. A cleaning mechanism 7 is arranged inside the cleaning tank 4.

[0029] See Figure 3 and Figure 4Furthermore, the adjusting mechanism 6 includes a lifting frame 601 slidably disposed within the first straightening frame 2, a threaded screw 602 rotatably disposed on the lifting frame 601, a threaded sleeve 604 threadedly connected to the threaded screw 602 and disposed through the first straightening frame 2, a moving block 609 fixedly disposed at the bottom of the second straightening frame 3, a slide groove 613 slidably connected to the moving block 609 and disposed on the machine body 1, and a bidirectional screw 610 threadedly connected to the moving block 609 and disposed rotatably within the slide groove 613; multiple... A first driven straightening roller 605, a first handwheel 603 fixedly connected to the top of the threaded screw 602, limit blocks 606 fixedly installed at both ends of the lifting frame 601, a limit groove 607 slidably connected to the limit block 606 is opened in the first straightening frame 2, a plurality of second driven straightening rollers 608 are rotatably installed in the second straightening frame 3, one end of the bidirectional screw 610 rotatably passes through the slide groove 613 and is fixedly connected to the second handwheel 611, and a guide rod 612 slidably connected to the moving block 609 is fixedly installed in the slide groove 613.

[0030] Specifically, by rotating the threaded screw 602 through the first handwheel 603, the lifting frame 601 can move up and down within the first straightening frame 2 under the action of the threaded sleeve 604, thus facilitating the adjustment of the distance between the active straightening roller 8 and the first driven straightening roller 605. By rotating the bidirectional screw 610 through the second handwheel 611, the two moving blocks 609 threadedly connected to the bidirectional screw 610 can move towards each other along the slide groove 613, thus facilitating the adjustment of the distance between the two sets of second driven straightening rollers 608 within the two second straightening frames 3, thereby realizing tension straightening of pipes of different diameters and effectively improving the applicability and versatility of the device.

[0031] See Figure 2 and Figure 5Furthermore, the cleaning mechanism 7 includes a water storage tank 702 mounted on the body 1, a water pump 704 mounted on the body 1 near the top of the cleaning tank 4, an inlet pipe of the water pump 704 connected to the water storage tank 702, an outlet pipe of the water pump 704 passing through the top of the cleaning tank 4 and connected to a nozzle 705, a connecting pipe 709 connecting the cleaning tank 4 and the water storage tank 702, a connecting frame 706 fixedly mounted inside the cleaning tank 4, a filter plate 707 slidably mounted on the connecting frame 706, a fixing plate 710 fixedly mounted inside the cleaning tank 4, and a hand-tightening screw 7 threadedly connected to the fixing plate 710. 11. One end of the hand-tightening screw 711 is rotatably connected to an arc-shaped plate 713. A limiting rod 712, which is fixedly connected to the arc-shaped plate 713, is slidably installed on the fixed plate 710. A scraper 714 is fixedly installed on the arc-shaped plate 713. Both ends of the cleaning tank 4 are provided with slots 701. A water inlet pipe 703 is connected to the water storage tank 702. One end of the filter screen plate 707 is fixedly connected to a handle 708. One side of the cleaning tank 4 is provided with an insertion port for the filter screen plate 707 to enter and exit. One end of the hand-tightening screw 711 and the limiting rod 712 rotatably penetrate the cleaning tank 4 and extend to the outer end of the cleaning tank 4.

[0032] Specifically, water pre-injected into the water storage tank 702 via the water injection pipe 703 is pumped into the nozzle 705 by the water pump 704. The sprayed water can wash away debris on the surface of the pipe. By turning the hand screw 711, the arc plate 713 can move under the guidance of the thread and the limit rod 712, which makes it easy to adjust the distance between the two arc plates 713 according to the diameter of the pipe. This allows the scraper 714 inside the arc plate 713 to be in close contact with the surface of the pipe, so that the scraper 714 can further scrape away the residual debris on the surface of the pipe after washing. This prevents debris from being discharged with the straightened pipe and polluting the working environment, thus improving the straightening quality of the pipe.

[0033] In actual operation, the pipe to be straightened is passed through the first straightening frame 2, the cleaning box 4 and the second straightening frame 3 in sequence through the guide seat 5 and placed on the guide seat 5 at the other end. By starting the motor 9, multiple active straightening rollers 8 are synchronized under the transmission action of the belt drive assembly 10, so that the pipe can be straightened and transported.

[0034] By rotating the threaded screw 602 with the first handwheel 603, the lifting frame 601 can move up and down within the first straightening frame 2 under the guidance of the limiting block 606 and the limiting groove 607, thus facilitating the adjustment of the distance between the active straightening roller 8 and the first driven straightening roller 605. By rotating the bidirectional screw 610 with the second handwheel 611, the two moving blocks 609 threadedly connected to the bidirectional screw 610 can move towards each other along the slide groove 613 under the guidance of the guide rod 612, thus facilitating the adjustment of the distance between the two sets of second driven straightening rollers 608 within the two second straightening frames 3, thereby realizing tension straightening of pipes of different diameters.

[0035] After the pipe is straightened by the first straightening frame 2, it enters the cleaning tank 4. Water pump 704 pumps water previously injected into the water tank 702 via the water injection pipe 703 into the spray nozzle 705. The sprayed water washes away debris from the pipe surface. Turning the hand-tightening screw 711 allows the arc-shaped plate 713 to move under the guidance of the thread and the limiting rod 712. This facilitates adjusting the distance between the two arc-shaped plates 713 according to the pipe diameter, allowing the scraper 714 inside the arc-shaped plate 713 to... The scraper 714 is close enough to the surface of the pipe so that it can further scrape off the residual debris on the surface of the pipe after rinsing. The wastewater mixed with debris is filtered by the filter screen 707 and falls into the cleaning tank 4 below the filter screen 707. It then flows back to the water storage tank 702 through the connecting pipe 709 to realize the recycling of water resources. When too much debris accumulates on the filter screen 707, the filter screen 707 can be pulled out along the overlapping frame 706 by the pull handle 708 to clean the debris on the filter screen 707.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
