Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of straightening machines, in particular to a steel pipe straightening machine. Background Art
[0002] The steel pipe straightening machine is a maintenance machine for steel pipes in building fastener-type steel pipe scaffolding. It is mainly used to straighten and repair steel pipes that are bent and deformed during construction. Its working principle is mainly to utilize the circular channel formed between multiple correction wheels. After the bent steel pipe enters the circular channel formed by multiple correction wheels, the steel pipe is deformed. Since the circular channels formed by multiple correction wheels are in a straight line distribution, the steel pipe becomes straight after passing through the channel, thereby achieving the purpose of straightening.
[0003] During the use of existing steel pipe straightening machines, mud or concrete blocks are easily adhered to the outer surface or inner ring of the steel pipe, and these adhered mud and concrete blocks will be squeezed during the steel pipe straightening process, thereby dispersing the extrusion force on the steel pipe and affecting the straightening of the steel pipe. Secondly, during the straightening process of the steel pipe, the steel pipe is affected by deformation, which causes stress inside the steel pipe, making the steel pipe more prone to deformation after straightening, affecting the normal use of the straightened steel pipe. Utility Model Content
[0004] In view of the shortcomings of existing steel pipe straightening machines, the utility model provides a steel pipe straightening machine, which can use vibration to remove mud blocks and the like adhering to the steel pipe, and use the principle of heating to eliminate the stress generated during the straightening of the steel pipe as much as possible, to ensure that the tail of the steel pipe can still be fixed when passing through the last set of straightening wheels, to ensure that the tail of the steel pipe can also be straightened, and solves the technical problems of mud blocks adhering to the steel pipe affecting straightening and stress generated during the steel pipe straightening process.
[0005] The utility model provides the following technical solution: a steel pipe straightening machine, including a support frame, and also including:
[0006] A placing table is fixedly mounted on the top of the supporting frame, a fixing plate is fixedly mounted on the right side of the top surface of the placing table, a driving box is fixedly mounted on the back of the fixing plate, and two pairs of output guide wheels are symmetrically mounted and movable on the front side of the fixing plate;
[0007] The lower mounting plate is fixedly mounted on the top surface of the support frame and is located on the left side of the fixed plate. An upper mounting plate is arranged on the upper side of the lower mounting plate. Correction wheels are movably mounted on the front sides of the lower mounting plate and the upper mounting plate. A telescopic device is fixedly connected to the top surface of the upper mounting plate. The bottom surface of the telescopic device is fixedly connected to the top surface of the support frame. A guide rod is fixedly mounted inside the lower mounting plate. The upper part of the guide rod is slidably sleeved with the upper mounting plate. A steel pipe is placed between the correction wheel on the lower mounting plate and the correction wheel on the upper mounting plate.
[0008] Preferably, the interior of the correction wheel includes:
[0009] A strong magnetic strip is fixedly arranged inside the correction wheel on the upper mounting plate.
[0010] Preferably, the support frame further includes:
[0011] A fixing rod, fixedly connected to the top surface of the placing table;
[0012] The collar is fixedly connected to the top end of the fixing rod.
[0013] Preferably, the collar comprises:
[0014] A sliding cavity, which is opened inside the upper side of the collar;
[0015] The spring is fixedly connected to the middle part of the top surface of the inner cavity of the sliding cavity.
[0016] Preferably, the spring comprises:
[0017] The magnetic block is fixedly connected to the bottom end of the spring. The magnetism of the magnetic block is opposite to that of the strong magnetic strip. The magnetic attraction of the strong magnetic strip on the magnetic block is greater than the elastic potential energy of the spring.
[0018] Preferably, the interior of the collar further includes:
[0019] An electromagnetic coil is fixedly arranged inside the collar and outside the sliding cavity;
[0020] The heating wire is fixedly arranged inside the lower side of the sleeve ring, and the output end of the electromagnetic coil is electrically connected to the heating wire through a wire.
[0021] Compared with the prior art, the utility model has the following beneficial effects:
[0022] 1. By designing strong magnetic strips, fixed rods, collars, springs and magnetic blocks, when the steel pipe is being straightened, since the steel pipe passes through the collar, the rotation of the correction wheel is used to drive the strong magnetic strip to rotate. When the strong magnetic strip rotates into the magnetic field range of the magnetic block, the strong magnetic strip will adsorb the magnetic block, causing the magnetic block to overcome the potential energy of the spring and move upward. When the strong magnetic strip is driven by the correction wheel to rotate out of the magnetic field range of the magnetic block, the magnetic block is bounced down by the elastic potential energy of the spring, causing the magnetic block to hit the steel pipe and cause the steel pipe to vibrate, thereby shaking off the mud blocks adhering to the steel pipe to prevent the mud blocks from affecting the straightening of the steel pipe.
[0023] 2. By designing the electromagnetic coil and the heating wire, as the correction wheel continuously drives the strong magnetic strip to rotate, the magnetic block is continuously reciprocated up and down inside the sliding cavity by the potential energy of the strong magnetic strip and the spring. The up and down reciprocating motion of the magnetic block cooperates with the electromagnetic coil to generate an electromagnetic effect between the electromagnetic coil and the magnetic block, prompting the electromagnetic coil to generate current. Through the conduction of the wire, the current generated by the electromagnetic coil is transmitted to the heating wire, prompting the heating wire to heat up, and the heat generated by the heating wire is used to heat the steel pipe, thereby reducing the stress generated during the straightening of the steel pipe and reducing the probability of the steel pipe cracking during straightening.
[0024] 3. Through the design of the fixing rod and the sleeve, the tail of the steel pipe will still be limited by the sleeve when passing through the last set of straightening wheels, ensuring that the tail of the steel pipe can be straightened, thereby improving the straightening effect.

[0031] See also Figure 1-Figure 4A steel pipe straightening machine comprises a support frame 1, a placing table 2 is fixedly installed on the top of the support frame 1, a fixing plate 3 is fixedly installed on the right side of the top surface of the placing table 2, a driving box 4 is fixedly installed on the back of the fixing plate 3, two pairs of output guide wheels 5 are symmetrically and movably installed on the front side of the fixing plate 3, a lower mounting plate 6 is fixedly installed on the top surface of the support frame 1 on the left side of the fixing plate 3, an upper mounting plate 7 is arranged on the upper side of the lower mounting plate 6, and correction wheels 8 are movably installed on the front sides of the lower mounting plate 6 and the upper mounting plate 7, which are driven by the driving box 4 The output guide wheel 5 and the correction wheel 8 rotate, and the top surface of the upper mounting plate 7 is fixedly connected with a telescopic device 9, which is used to control the upward and downward movement of the upper mounting plate 7, thereby adjusting the spacing between the correction wheels 8. The bottom surface of the telescopic device 9 is fixedly connected with the top surface of the support frame 1, and a guide rod 10 is fixedly installed inside the lower mounting plate 6. The upper part of the guide rod 10 is slidably connected with the upper mounting plate 7 to facilitate the upper mounting plate 7 to slide up and down along the guide rod 10. A steel pipe 11 is placed between the correction wheel 8 on the lower mounting plate 6 and the correction wheel 8 on the upper mounting plate 7.
[0032] See also Figure 1-Figure 4 A strong magnetic strip 81 is fixedly arranged inside the correction wheel 8 on the upper mounting plate 7.
[0033] See also Figure 1-Figure 4 A fixing rod 82 is fixedly welded to the top surface of the placement table 2.
[0034] A collar 83 is fixedly welded to the top of the fixing rod 82 , and the collar 83 is supported by the fixing rod 82 to ensure that the collar 83 and the steel pipe 11 are in the same straight line, so that the tail of the steel pipe 11 can also be straightened.
[0035] See also Figure 1-Figure 4 A sliding cavity 84 is provided inside the upper side of the sleeve ring 83 , and a spring 85 is fixedly welded to the middle of the top surface of the sliding cavity 84 .
[0036] See also Figure 1-Figure 4 A magnetic block 86 is fixedly welded to the bottom end of the spring 85. The magnetism of the magnetic block 86 is opposite to that of the strong magnetic strip 81. The magnetic attraction of the strong magnetic strip 81 on the magnetic block 86 is greater than the elastic potential energy of the spring 85. After the strong magnetic strip 81 leaves the magnetic block 86, the elastic potential energy of the spring 85 drives the magnetic block 86 to move downward and hit the outer surface of the steel pipe 11, causing the steel pipe 11 to vibrate.
[0037] See also Figure 1-Figure 4 An electromagnetic coil 87 is fixedly installed inside the ring 83 and on the outside of the sliding cavity 84, and an electric heating wire 88 is fixedly installed inside the lower side of the ring 83. The output end of the electromagnetic coil 87 is electrically connected to the electric heating wire 88 through a wire to ensure that the current generated by the electromagnetic coil 87 can be transmitted to the electric heating wire 88, causing the electric heating wire 88 to heat up and heat the steel pipe 11.
[0038] Working principle: When the steel pipe 11 is straightened, the steel pipe 11 is placed between the straightening wheel 8 on the lower mounting plate 6 and the straightening wheel 8 on the upper mounting plate 7. Since the steel pipe 11 passes through the collar 83, the tail of the steel pipe 11 can still be well limited when passing through the last set of straightening wheels 8, and no positional deviation will occur, thereby ensuring that the tail of the steel pipe 11 can also be straightened, thereby improving the straightening effect. At the same time, due to the rotation of the straightening wheel 8 during the straightening process, the straightening wheel 8 will drive the strong magnetic strip 81 to rotate. When the strong magnetic strip 81 rotates to the magnetic field range of the magnetic block 86, the magnetic block 86 will be adsorbed by the strong magnetic strip 81 and overcome the elastic potential energy of the spring 85 to move upward. When the strong magnetic strip 81 leaves the magnetic field range of the magnetic block 86, the magnetic block 86 will be moved downward by the elastic potential energy of the spring 85 and hit the outer surface of the steel pipe 11. This causes the steel pipe 11 to vibrate, and at this time, the vibration is used to remove the mud adhered to the outer surface of the steel pipe 11, so as to prevent the mud from adhering to the outer surface of the steel pipe 11 and affecting the straightening. Secondly, due to the continuous rotation of the straightening wheel 8, the strong magnetic strip 81 will periodically rotate to the magnetic field range of the magnetic block 86, so as to use the cooperation between the strong magnetic strip 81 and the spring 85 to make the magnetic block 86 reciprocate up and down in the sliding cavity 84. At this time, the up and down reciprocating magnetic block 86 cooperates with the electromagnetic coil 87 to produce an electromagnetic effect, causing the electromagnetic coil 87 to generate current, and the current generated by the electromagnetic coil 87 is transmitted to the heating wire 88 by a wire, causing the heating wire 88 to heat up and heat the steel pipe 11, thereby reducing the stress generated during the straightening of the steel pipe 11 as much as possible through the heating method, and reducing the probability of deformation of the steel pipe 11 after straightening.
