Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 6 The utility model provides a bending machine with a fixed clamping mechanism, including a main frame 1 and a rotating groove 3, a control panel 2 is installed on one side of the main frame 1, a rotating groove 3 is opened on one side of the top inner part of the main frame 1, and a guide groove 5 is opened on the other side of the top inner part of the main frame 1. The inner part of the rotating groove 3 is rotatably connected with a bending structure 4, and the bending structure 4 includes a bending seat 401, a slide groove 402, a bending column 403, a turntable 404, an adjusting thread 405, a threaded push block 406, an adjusting tooth 407, an adjusting screw 408, an adjusting countersunk head 409 and an intermediate column 410. The bending seat 401 is rotatably connected to the inner part of the rotating groove 3, a slide groove 402 is opened on one side of the top inner part of the bending seat 401, and the inner slide groove 402 is A bending column 403 is rotatably connected, and a turntable 404 is rotatably connected inside the bending seat 401. An adjusting thread 405 is provided at the top of the turntable 404. A threaded push block 406 is provided at the bottom end of the bending column 403. An adjusting tooth 407 is provided at the bottom end of the turntable 404. An adjusting screw 408 is rotatably connected to the bottom end of one side of the inner part of the bending seat 401. An adjusting countersunk head 409 is fixedly connected to one side of the adjusting screw 408. An intermediate column 410 is rotatably connected to the top of the bending seat 401. The slide groove 402 and the bending column 403 are in a sliding structure. The adjusting thread 405 and the threaded push block 406 are in a threaded connection structure. The adjusting tooth 407 and the adjusting screw 408 are in a meshing structure. The bending seat 401 and the adjusting countersunk head 409 are in a rotating structure.

[0025] See attached Figure 1 , Figure 2 , Figure 3 and Figure 4When the bending machine is used, building materials such as metal pipes are placed on the inner side of two sets of clamping frames 603 in a set of guide grooves 5, and the other end of the building material is passed through the inner side of the bending column 403 and the middle column 410, and then the motor is started to drive the bending seat 401 to rotate in a certain direction, and the building material passing through the inner side of the bending column 403 and the middle column 410 is bent. In this process, if the bent building material is thicker and the distance between the bending column 403 and the middle column 410 is closer, the bending column 403 and the middle column 410 are subjected to greater pressure when the building material is bent, and long-term use may easily cause them to bend or break. For this reason, the bending machine is used. When in use, the distance between the bending column 403 and the middle column 410 can be adjusted according to the thickness of the building material. At this time, the adjusting countersunk head 409 is rotated by a special wrench to drive the adjusting screw 408 together. Since the adjusting tooth 407 and the adjusting screw 408 are in a meshing structure, when the adjusting screw 408 rotates, the turntable 404 will also be driven. Since the adjusting thread 405 and the threaded push block 406 are in a threaded connection structure, when the turntable 404 rotates, the bending column 403 will also slide along the slide groove 402. In this way, the distance between the bending column 403 and the middle column 410 can be adjusted by controlling the forward and reverse rotation of the adjusting countersunk head 409, and the pressure on them can be reduced by increasing their distance.

[0026] The guide groove 5 is internally slidably connected with a fastening and clamping structure 6, which includes a bidirectional threaded rod 601, an internal threaded seat 602, a clamping frame 603, an internal threaded tube 604, a fastening screw 605 and an anti-skid pressure plate 606. The bidirectional threaded rod 601 is rotatably connected to one side of the top end inside the main frame 1, the outer side of the bidirectional threaded rod 601 is threadedly connected to the internal threaded seat 602, the top of the internal threaded seat 602 is fixedly connected to the clamping frame 603, the top of the clamping frame 603 is fixedly connected to the internal threaded tube 604, the internal thread of the internal threaded tube 604 is connected with the fastening screw 605, and the bottom end of the fastening screw 605 is rotatably connected to the anti-skid pressure plate 606, the bidirectional threaded rod 601 and the internal threaded seat 602 are in a threaded connection structure, the clamping frame 603 and the guide groove 5 are in a sliding structure, four groups of clamping frames 603 are provided, and the interior of each group of guide grooves 5 is symmetrically slidably connected to two groups of clamping frames 603.

[0027] See attached Figure 1 , Figure 2 , Figure 5 and Figure 6When the bending machine is in use, since the diameters of steel pipe building materials of different specifications are different, in order to avoid shaking or falling of the building materials during the bending process and thus affecting the bending effect, the building materials are placed on the inner side of the two groups of clamping frames 603, and then the handle at one end of the two-way threaded rod 601 is rotated to rotate the two-way threaded rod 601. At this time, the internal thread seat 602 threadedly connected to the two-way threaded rod 601 gradually pushes the clamping frame 603 to move along the guide groove 5. Since two-way threads are provided on both sides of the outer wall of the two-way threaded rod 601, and each group of two-way threads is threadedly connected to two groups of internal thread seats 602, when the two-way threaded rod 601 rotates, the clamping frame 603 located inside the same group of guide grooves 5 will move in the opposite direction and clamp and tighten the building materials. Then, the tightening screw 605 is tightened to drive the anti-slip pressure plate 606 to press and tighten the top of the building materials, so that the building materials can remain stable during bending.
