Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending machine components, in particular to a positioning support device for a pipe bending machine. Background Art

[0002] Pipe bending machine refers to a machine used for bending pipes and can also be used as a jack. It is roughly divided into CNC pipe bending machine, hydraulic pipe bending machine, etc. It is used in power construction, road and railway construction, bridges, ships and other aspects of pipeline laying and repair. Pipe bending machine can be roughly divided into CNC pipe bending machine, hydraulic pipe bending machine, etc. It is mainly used for power construction, railway construction, pipeline laying and repair of boilers, bridges, ships, furniture, decoration, etc. It has the advantages of multiple functions, reasonable structure and simple operation.

[0003] During the use of the pipe bending machine, the pipe needs to be clamped and fixed for a hundred years for the bending operation. Different pipes require different clamping and positioning positions when bent at different angles. In addition, the inappropriate torque used between bending and clamping often causes internal stress damage to the bent pipe during timing. The existing positioning support device is inconvenient to adjust, and cannot assist in detecting the maximum bending force according to the displacement stress at different positions of the pipe when bending. Based on this, we propose a positioning support device for a pipe bending machine. Utility Model Content

[0004] The purpose of the utility model is to provide a positioning support device for a pipe bending machine to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a positioning support device for a pipe bending machine, comprising a support, a plurality of slide grooves are provided on the top of the support, a slide rod is fixedly installed inside the slide groove, a slider is slidably sleeved on the outer side of the slide rod, a support plate is fixedly installed on the top of the slider, a plurality of mounting holes are provided on the top of the support plate, a plurality of positioning plates are fixedly installed on the top of the support plate, a stud is connected through the internal thread of the positioning plate, a crank is fixedly installed on one end of the stud, and an axle seat is movably sleeved on the outer side of the other end of the stud, A clamping plate is fixedly installed on the other side of the shaft seat, a sliding bracket is fixedly installed on the bottom of the clamping plate, a plurality of pin holes are opened on the outer side of the stud, a pin is movably inserted on the top of the positioning plate, a mounting support tube is movably installed on the top of the support plate, a sleeve is fixedly installed on one end of the mounting support tube, a resistance coil is wound around the inner wall of the sleeve, a charged sliding column is movably sleeved on the inner side of the resistance coil, an insulating spring is fixedly installed on one end of the charged sliding column, an insulating contact is fixedly installed on the other end of the charged sliding column, and a bending pipe mechanism is provided at one end of the support.

[0006] Preferably, the slide grooves are linearly symmetrically and evenly distributed on the top of the support, and the sliding blocks are slidably installed inside the slide grooves.

[0007] Preferably, the mounting holes are linearly symmetrical and evenly staggered with the positioning plates on the top of the support plate, the mounting holes penetrate the support plate and extend to the interior of the support, and the mounting support tube is fixed to the top of the support plate by bolts penetrating the mounting holes.

[0008] Preferably, one end of the slide is located on the clamping plate and is in sliding contact with the top of the support plate, and the other end of the slide slides through the positioning plate and extends to the bottom of the stud.

[0009] Preferably, the pin holes are evenly distributed on the outside of the stud in a spiral shape, and the specifications and dimensions of the pins are matched with the specifications and dimensions of the pin holes.

[0010] Preferably, the charged sliding column movably passes through the mounting support tube and extends to the outside of the mounting support tube, the insulating spring is sleeved inside the sleeve and the resistance coil, and one end of the insulating spring away from the charged sliding column is fixedly installed inside the sleeve.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: when the device is used, the support and the pipe bending mechanism are installed at the power output of the pipe bending machine, and then the pipe to be bent is placed on the top of the support plate and the opposite side of the clamping plate. At this time, the crank is turned to drive the stud, and the thread between the stud and the positioning plate rotates and extends, and drives the shaft seat and the clamping plate to extend, so that the clamping plate fits the outside of the pipe, and then the pin is inserted into the positioning plate and the pin hole to fix the position of the stud to avoid loosening. After positioning, the pipe bending operation is performed through the pipe bending mechanism. Due to the setting of the slide groove and the slide rod, the support plate can be slidably adjusted at the required position, which can assist the pipe bending operation and can be fixed by the installation hole to assist in adjustment. The overall adjustment is convenient to cope with pipe bending at different angles, and the overall efficiency is improved.

[0012] By setting up the charged sliding column and insulating contacts, when it is necessary to measure the maximum stress of different pipeline bends, the insulating contacts are positioned and clamped in a fixed position so that they fit the outside of the pipeline. As the bending force gradually increases, the pipeline is displaced and deformed. At this time, the insulating contacts are displaced by the force and push the charged sliding column, causing the microcurrent between the charged sliding column and the resistance coil to change. The displacement of the pipeline of the bend can be determined by measuring the value and fluctuation of the microcurrent change, which is convenient for auxiliary measurement and auxiliary bending operations, and indirectly improves the yield rate.

[0020] The working principle of the above technical solution is as follows: when in use, the support 1 and the pipe bending mechanism 2 are installed at the power output of the pipe bending machine, and then the pipe to be bent is placed on the top of the support plate 3 and the opposite side of the clamping plate 7. At this time, the crank 10 is turned to drive the stud 8, and the thread between the stud 8 and the positioning plate 6 is rotated and extended, and the shaft seat 13 and the clamping plate 7 are driven to extend, so that the clamping plate 7 fits the outside of the pipe. Then the pin 9 is inserted into the positioning plate 6 and the pin hole 15 to fix the position of the stud 8 to prevent loosening. After positioning, the pipe bending operation is performed through the pipe bending mechanism 2. Due to the setting of the slide groove 4 and the slide rod 5, the support plate 3 can be slid and adjusted at the required position, which can assist the pipe bending operation and can be fixed by the mounting hole 12 to assist in adjustment. The overall adjustment is convenient to cope with bending of pipes at different angles, and the overall efficiency is improved.

[0021] In another embodiment, Figure 1-Figure 4 As shown, the slide grooves 4 are evenly distributed on the top of the support 1 in a linear symmetrical manner, and the slider 14 is slidably installed inside the slide grooves 4 .

[0022] The slide groove 4 cooperates with the slide rod 5 to assist in the operation, and prevents the slider 14 from deflecting when subjected to a lateral force, thereby stabilizing the positions of the slider 14 and the support plate 3, facilitating the auxiliary operation, and providing a good overall structure.

[0023] In another embodiment, Figure 1-Figure 4 As shown, the mounting holes 12 are linearly symmetrical and evenly staggered with the positioning plates 6 on the top of the support plate 3. The mounting holes 12 penetrate the support plate 3 and extend to the inside of the support 1. The mounting support tube 16 is fixed to the top of the support plate 3 by bolts penetrating the mounting holes 12.

[0024] The mounting hole 12 can provide a fixed position for mounting the support tube 16 and a fixed position for fixing the support plate 3 on the support 1, thereby providing a point for auxiliary fixation, facilitating stable operation and increasing adaptability.

[0025] In another embodiment, Figure 1-Figure 4 As shown, one end of the slide 11 is located on the clamping plate 7 and is in sliding contact with the top of the support plate 3 , and the other end of the slide 11 slides through the positioning plate 6 and extends to the bottom of the stud 8 .

[0026] The slide 11 provides a lateral sliding limit for the splint 7 to prevent the splint 7 from flipping over after being subjected to force, thereby stabilizing the position of the splint 7 and assisting the operation. The overall structure runs smoothly and avoids misalignment.

[0027] In another embodiment, Figure 1-Figure 3 As shown, the pin holes 15 are evenly distributed on the outside of the stud 8 in a spiral shape, and the specifications and dimensions of the pin 9 are matched with the specifications and dimensions of the pin holes 15.

[0028] The spiral path of the pin hole 15 matches the stud 8, which is convenient for fixing the position between the structures, and for firmly fixing the fixed point after the stud 8 is adjusted, so as to increase the firmness and achieve a good use effect.

[0029] In another embodiment, Figure 4 As shown, the charged sliding column 17 moves through the mounting support tube 16 and extends to the outside of the mounting support tube 16, the insulating spring 21 is sleeved inside the sleeve 19 and the resistance coil 20, and the end of the insulating spring 21 away from the charged sliding column 17 is fixedly installed inside the sleeve 19.

[0030] By setting the charged sliding column 17 and the insulating contact 18, when it is necessary to measure the maximum stress of different pipe bends, the insulating contact 18 is positioned and clamped in a fixed position so as to fit the outside of the pipe. As the bending force gradually increases, the pipe is displaced and deformed. At this time, the insulating contact 18 is displaced by the force and pushes the charged sliding column 17. The microcurrent between the charged sliding column 17 and the resistance coil 20 changes. The displacement of the pipe of the bend can be known by measuring the value and fluctuation of the microcurrent change, which is convenient for auxiliary measurement and auxiliary bending operations, and indirectly improves the yield rate.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
