Description
Technical Field
[0001] The utility model relates to the technical field of pipe fitting processing, in particular to a bending device used for pipe fitting processing. Background Art
[0002] Pipe bending is the process of bending pipes through bending equipment to obtain the desired shape and angle. Bending equipment usually consists of a frame, a bending die, a clamping device and a drive system. During the bending process, the pipe is clamped on the bending die, and then force is applied through the drive system to bend the pipe.
[0003] It is not easy for traditional bending equipment to accurately control the bending parameters during the bending process; and for pipes of different diameters and shapes, different clamping molds need to be replaced, which increases production costs and processing time.
[0004] To this end, we propose a bending device for pipe processing. Utility Model Content
[0005] The main purpose of the utility model is to provide a bending device for pipe processing, in order to facilitate operation, thereby improving the bending device's ability to accurately control various parameters, reducing dependence on different molds, and ultimately improving production efficiency and reducing costs, which can effectively solve the problems in the background technology.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] The top of the machine tool is slidably connected to a first sliding base and a second sliding base, and the tops of the first sliding base and the second sliding base are respectively provided with a rotating mechanism and a clamping mechanism. The rotating mechanism comprises a fixed block fixedly connected to the top of the first sliding base, a rotating shaft is rotatably connected inside the fixed block, a rotating disk is welded at one end of the rotating shaft, and a rotating block is fixedly connected to the other end of the rotating shaft, a limiting groove is provided on the side of the rotating block away from the rotating shaft, a screw rod is rotatably connected inside the limiting groove, two groups of relatively output thread grooves are provided on the outside of the screw rod, and the first clamping plate is threadedly connected to the outside of the two groups of thread grooves, and one end of the rotating block is fixedly connected to a motor, and an output end of one end of the motor passes through the rotating block and is fixedly connected to one end of the screw rod;
[0008] The clamping mechanism includes a fixed seat fixedly connected to the top of the second sliding base and a telescopic rod, the top of the fixed seat is fixedly connected to the first curved plate, a second curved plate arranged in a mirror image is provided directly above the first curved plate, the first curved plate and the second curved plate are both provided with a first sliding groove inside, an arc-shaped slider is slidably connected inside the first sliding groove, an arc-shaped support block is fixedly connected to the inner side of the arc-shaped slider away from the first sliding groove, a plurality of groups of springs are provided on the inner side of the arc-shaped support block, and the second clamping plate is fixedly connected to one end of the spring away from the arc-shaped support block;
[0009] The lower outer part of the second curved plate and the upper outer part of the first curved plate are both provided with connecting blocks that fit together. The top end of the telescopic rod passes through the connecting block at the upper outer part of the first curved plate and is fixedly connected to the connecting block at the lower outer end of the second curved plate.
[0010] By adopting the above technical solution, the first sliding base and the second sliding base can slide on the top of the machine tool so as to adjust the position as needed; when the workpiece needs to be operated, the motor in the rotating mechanism is started, and the motor drives the screw to rotate; because there are two sets of relatively output thread grooves on the screw, this will cause the two first clamping plates to move relative to or away from each other along the screw, thereby clamping or loosening the workpiece. After the workpiece is clamped, the rotating shaft and the clamped workpiece can be driven to rotate through the turntable to adjust the angle of the workpiece; at the same time, the clamping mechanism can be used to clamp and fix other parts of the workpiece to cooperate with the rotating mechanism to complete corresponding bending and other operations. Through the mobility of the sliding base and the coordinated work of the rotating mechanism and the clamping mechanism, flexible processing of the workpiece at different positions and angles can be achieved;
[0011] When a clamping operation is required, the telescopic rod is controlled to extend and retract to push the second arc plate to move up and down relative to the first arc plate, and the arc sliders in the first arc plate and the second arc plate can slide in the first slide groove, thereby ensuring that the pipe rotates together with the rotating block when clamping. When the workpiece is clamped, multiple groups of springs play a certain buffering and adaptive role, which can make the second clamping plate better fit the surface of the workpiece and enhance the stability and reliability of clamping. Through this structural design, it can adapt to workpieces of different shapes and sizes for effective clamping and fixing;
[0012] In the clamping mechanism, the lower outer part of the second curved plate and the upper outer part of the first curved plate are equipped with connecting blocks, which play the role of connecting and transmitting the force. The top end of the telescopic rod passes through the middle of the connecting block on the upper outer part of the first curved plate, and then is firmly fixed to the connecting block on the lower outer end of the second curved plate. In this way, when the telescopic rod is telescoped, the second curved plate can be driven to move up and down relative to the first curved plate through the connecting block, thereby realizing the clamping or releasing operation of the workpiece. This structural design ensures the accurate and stable execution of the clamping action.
[0013] Furthermore, the top of the machine tool close to the first sliding base is fixedly connected to a limit plate, and both sides of the top of the machine tool away from the limit plate are fixedly connected to support frames.
[0014] By adopting the above technical solution, the limit plate is used to limit the moving range of the first sliding base to a certain extent.
[0015] Furthermore, a second slide groove is provided inside the support frame, a limiting block is slidably connected inside the second slide groove, and a bending plate is fixedly connected to one end of the limiting block away from the second slide groove.
[0016] By adopting the above technical solution, a second slide groove is set on the support frame, which provides a track for the movement of the limit block. The limit block can slide smoothly in the second slide groove, and the bending plate is fixedly connected to the limit block, so that when the limit block moves along the second slide groove, it can drive the bending plate to move synchronously.
[0017] Furthermore, a support plate is fixedly installed on the inner upper portion of the support frame, and a placement rod is fixedly installed on the inner lower portion of the support frame.
[0018] By adopting the above technical solution, the placement rod is used to place the bent end of the pipe.
[0019] Furthermore, a hydraulic cylinder is fixedly connected to the middle portion of the top end of the support plate.
[0020] By adopting the above technical solution, the support plate plays a supporting role for the hydraulic cylinder.
[0021] Furthermore, the output end of the bottom end of the hydraulic cylinder passes through the support plate and is fixedly connected to the middle part of the top end of the bending plate.
[0022] By adopting the above technical solution, when the hydraulic cylinder is working, its output end will perform a telescopic movement. Since the output end at the bottom of the hydraulic cylinder passes through the support plate and is fixedly connected to the middle of the top end of the bending plate, when the output end of the hydraulic cylinder is extended, it will push the bending plate to move downward along the second slide groove; when the output end is retracted, it will drive the bending plate to move upward, thereby achieving precise control of the position of the bending plate, so that it can bend the workpiece as needed. Through this hydraulic drive method, greater force and relatively stable motion control can be provided to ensure the smooth progress and high-quality completion of operations such as bending.

The motor in the rotating mechanism drives the screw to rotate, and the special thread groove design is used to realize the relative or opposite movement of the first clamping plate, so as to accurately clamp or release the workpiece, and the turntable can drive the workpiece to rotate to adjust the angle, which has high flexibility. At the same time, the clamping mechanism can stably clamp other parts of the workpiece and work in conjunction with the rotating mechanism to complete operations such as bending. The combination of the two enables the workpiece to be flexibly and accurately processed at different positions and angles.
[0026] (3) The utility model discloses a bending device for pipe processing. During the clamping operation, the telescopic rod controls the second curved plate to move relative to the first curved plate. The curved slider slides in the first slide groove to ensure that the pipe rotates with the rotating block. The buffering and adaptive effects of the spring enable the second clamping plate to better fit the workpiece, thereby improving the stability and reliability of clamping. This design can adapt to workpieces of different shapes and sizes for effective clamping. In addition, the coordination of the connecting block and the telescopic rod ensures the accurate and stable execution of the clamping action. The overall structure of the bending device is reasonable and the operation is convenient.
