Description

Technical Field

[0001] This invention relates to the field of steel straightening technology, specifically to a steel profile straightening device. Background Technology

[0002] Steel is a malleable material, but residual stress exists during its production process. This residual stress is irregularly distributed, which can cause deformation and bending in the produced steel. Therefore, the steel generally needs to be straightened and corrected before leaving the factory. Steel straightening equipment mainly consists of a frame, two support seats fixed on the frame, and cylinders mounted on the support seats. In use, the two ends of the steel are placed on the two support seats, and the hydraulic cylinders are activated to apply point pressure to straighten the steel.

[0003] Patent CN213968406U relates to the field of steel straightening technology, specifically a novel steel straightening device. It solves the problem that existing steel straightening devices are inconvenient for automatically straightening steel. It includes a base, a support column on one side of the top surface of the base, a horizontally extending connecting plate on the support column, and an end of the connecting plate extending away from the support column to the other side of the base. A longitudinally extending cylinder is located at the bottom of the connecting plate, and a straightening body is fixedly connected to the bottom end of the piston rod on the cylinder. A horizontally extending straightening groove is formed on the base, and the straightening body is located directly above the straightening groove. This patent automatically straightens the steel by driving the cylinder to move the piston rod downwards, causing the straightening body to move towards the steel.

[0004] Although the aforementioned patent can correct the deformation of steel, it cannot correct the protrusions inside hollow steel sections, resulting in deformation on the surface of the steel section and thus certain defects. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a steel profile straightening device that solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a steel profile straightening device includes a placement base plate. Two limiting blocks are fixed to the top and bottom right sides of the placement base plate. A gap is provided between the two limiting blocks located at the same end of the placement base plate, and a control screw is disposed in the gap between the two limiting blocks. The control screw movably penetrates the placement base plate and is rotatably connected to it. The left end of the control screw extends to the left side of the placement base plate and is fixedly connected to the output shaft of a control motor. The control motor is fixedly installed on the left side of the placement base plate. A straightening pressure rod is disposed on the right side of the placement base plate. A threaded block passes through the right end of the rod and is threadedly connected to the threaded block. The threaded block is fixedly connected to the end of the straightening pressure rod. The steel profile is placed on the right side of the placement base plate, with the top of the steel profile contacting the bottom of the support plate and the bottom contacting the limiting block. The forward switch of the control motor is turned on, and the output shaft of the control motor drives the control screw to rotate. Under the thread action of the control screw and the threaded block, the straightening pressure rod moves to the left and pushes and squeezes the steel profile to straighten. After the straightening is completed, the reverse switch of the control motor is turned on, and the output shaft of the control motor reverses and drives the threaded block and the straightening pressure rod to move to the right through the control screw. An internal straightening device is provided on the rear side of the placement base plate.

[0007] Preferably, an elastic support assembly is provided on the limiting block located at the top of the placement substrate. The elastic support assembly includes a movable column and a support plate. The top end of the movable column is slidably installed inside the limiting hole, which is opened at the bottom of the limiting block located at the top of the placement substrate. A support spring is fixedly installed on the top of the movable column, and the top end of the support spring is fixedly installed on the top of the limiting hole. The support plate is fixedly connected to the bottom of the movable column, and the depth of the limiting hole is greater than the length of the movable column.

[0008] Preferably, the internal correction device includes a storage compartment, an internal support column, and a drive mechanism. The storage compartment is fixedly installed on the rear side of the placement substrate, and a storage slot is provided on the front side of the storage compartment. The bottom height of the storage slot is the same as the top height of the limiting block located at the bottom of the placement substrate. A solid part is provided between the top of the storage compartment and the top of the storage slot. The internal support column passes through and is slidably installed on the solid part in the vertical direction. The left side of the internal support column is connected to the drive mechanism, and the drive mechanism is installed on the top of the placement substrate.

[0009] Preferably, the driving mechanism includes a toothed groove, a gear, and a drive motor. The toothed groove is located on the left side of the inner support column, and the right side of the gear meshes with the toothed groove. The output shaft of the drive motor is fixed at the center of the gear, and the drive motor is fixedly mounted on the top of the placement substrate. When the profile is pushed into the storage slot, the switch of the drive motor is turned on, and the output shaft of the drive motor drives the gear to rotate. The gear drives the inner support column to descend through the toothed groove on the left side of the inner support column. The inner support column is inserted into the profile and squeezes the inner protrusions inside the profile, so that the depressions on the surface of the profile can be squeezed and repaired, thereby achieving complete straightening of the profile.

[0010] Preferably, the storage tank is equipped with a top positioning mechanism, which includes a top positioning block, a limiting strip, and a transmission frame. The top positioning block movably passes between the rear side of the storage tank and the rear side of the storage compartment. One end of the limiting strip is inserted into the insertion hole at the top of the top positioning block, and the top end of the limiting strip is fixedly connected to the transmission frame. A connecting strip is fixed at the bottom of the transmission frame, and the bottom end of the connecting strip is fixedly connected to the top of the movable column. Before straightening, the steel profile is shorter due to the curvature. During the straightening process, the steel profile gradually recovers its length, thereby pushing the support plate and the movable column upward and compressing the support spring. During the upward movement of the movable column, the connecting strip is driven upward, and the connecting strip drives the transmission frame upward. The transmission frame drives the limiting strip upward and disengages from the top positioning block. At this time, the steel profile is pushed, and the steel profile can push the top positioning block backward, preventing the steel profile from moving backward during the external straightening process and affecting the straightening effect.

[0011] Preferably, a top spring is fixedly connected to the rear side of the top block, and a connecting frame is fixedly connected to the end of the top spring away from the top block. The connecting frame is fixedly connected to the rear side of the storage compartment. A blocking opening is provided on the inner wall of the storage slot. Blocking blocks are fixed at the top and bottom of the front side of the top block, and the blocking blocks and the blocking opening are at the same height.

[0012] Preferably, a reciprocating striking mechanism is provided at the output shaft of the drive motor. The reciprocating striking mechanism includes a drive cam, a reciprocating plate, and a striking bar. The drive cam is fixedly connected to the output shaft of the drive motor. The left side of the reciprocating plate contacts the drive cam, and the rear side is fixedly connected to the striking bar. The end of the striking bar away from the reciprocating plate is located on the right side of the inner support column. During the rotation of the output shaft of the drive motor, the drive cam will be driven to rotate. During the rotation of the drive cam, the reciprocating plate will be pushed to move back and forth, thereby causing the reciprocating plate to drive the striking bar to move back and forth. During the reciprocating movement of the striking bar, it strikes the inner support column, thereby making the connection between the inner support column and the steel section more compact through vibration.

[0013] Preferably, a sliding bar is fixedly connected to the right side of the reciprocating plate. The bottom end of the sliding bar is slidably mounted on the right side of the storage compartment, and a return spring is fixedly connected to the bottom end of the sliding bar. The end of the return spring away from the sliding bar is fixedly connected to the storage compartment.

[0014] This invention provides a steel profile straightening device. It has the following beneficial effects: (1) The steel profile straightening equipment uses a control motor, control screw, threaded block and straightening pressure rod to push and squeeze the steel profile straightening. After straightening, the steel profile is pushed into the storage tank. The drive motor is turned on and the output shaft of the drive motor drives the gear to rotate. The gear drives the inner support column to descend through the tooth groove on the left side of the inner support column. The inner support column is inserted into the steel profile and squeezes the inner protrusion inside the steel profile, so that the depression on the surface of the steel profile can be squeezed and repaired, thereby achieving complete straightening of the steel profile.

[0015] (2) In the process of straightening the steel profile, the steel profile will push the support plate and the movable column to rise and squeeze the support spring. During the process of the movable column rising, the connecting strip will rise and the connecting strip will drive the transmission frame to rise. The transmission frame will drive the limit insert to rise and disengage from the top block. At this time, the steel profile will be pushed and the steel profile can push the top block to move backward, so as to prevent the steel profile from moving backward during the external straightening process and affecting the straightening effect.

[0016] (3) In the process of the output shaft of the drive motor rotating, the drive cam will rotate. During the rotation of the drive cam, the reciprocating plate will move back and forth, thereby causing the reciprocating plate to move back and forth. During the reciprocating movement of the reciprocating plate, the inner support column will be struck, thereby making the connection between the inner support column and the steel more compact through vibration.

The forward switch of the control motor 12 is turned on, and the output shaft of the control motor 12 drives the control screw 2 to rotate. Under the thread action of the control screw 2 and the threaded block 31, the straightening pressure rod 3 moves to the left and pushes and squeezes the profile to straighten. After the straightening is completed, the reverse switch of the control motor 12 is turned on, and the output shaft of the control motor 12 reverses and drives the threaded block 31 and the straightening pressure rod 3 to move to the right through the control screw 2. An internal straightening device 4 is provided on the rear side of the placement base plate 1.

[0021] An elastic support component 5 is provided on the limiting block 11 located at the top of the placement substrate 1. The elastic support component 5 includes a movable column 51 and a support plate 52. The top end of the movable column 51 is slidably installed inside the limiting hole. The limiting hole is opened at the bottom of the limiting block 11 located at the top of the placement substrate 1. A support spring is fixed to the top of the movable column 51. The top end of the support spring is fixedly installed at the top of the limiting hole. The support plate 52 is fixedly connected to the bottom of the movable column 51. The depth of the limiting hole is greater than the length of the movable column 51.

[0022] The internal correction device 4 includes a storage compartment 41, an internal support column 42, and a drive mechanism 43. The storage compartment 41 is fixedly installed on the rear side of the placement substrate 1, and a storage slot 411 is provided on the front side of the storage compartment 41. The bottom height of the storage slot 411 is the same as the top height of the limiting block 11 located at the bottom of the placement substrate 1.

[0023] The drive mechanism 43 includes a toothed groove 431, a gear 432, and a drive motor 433.

The output shaft of the drive motor 433 is fixed at the center of the gear 432, and the drive motor 433 is fixedly installed on the top of the placement base plate 1. When the profile is pushed into the storage slot 411, the switch of the drive motor 433 is turned on, and the output shaft of the drive motor 433 drives the gear 432 to rotate. The gear 432 drives the inner support column 42 to descend through the toothed groove 431 on the left side of the inner support column 42. The inner support column 42 is inserted into the profile and squeezes the inner protrusions inside the profile, so that the depressions on the surface of the profile can be squeezed and repaired, thereby achieving complete straightening of the profile.

[0024] The storage tank 411 is equipped with a top positioning mechanism 6, which includes a top positioning block 61, a limiting insert 62, and a transmission frame 63. The top positioning block 61 movably passes between the rear side of the storage tank 411 and the rear side of the storage compartment 41. One end of the limiting insert 62 is inserted into the insertion hole at the top of the top positioning block 61, and the top end of the limiting insert 62 is fixedly connected to the transmission frame 63. A connecting strip 511 is fixedly attached to the bottom of the transmission frame 63, and the bottom end of the connecting strip 511 is fixedly connected to the top of the movable column 51. Due to the curvature, the front section is relatively short. During the straightening process, the section steel gradually recovers its length, which pushes the support plate 52 and the movable column 51 to rise and squeeze the support spring. During the rise of the movable column 51, the connecting strip 511 is driven to rise, and the connecting strip 511 drives the transmission frame 63 to rise. The transmission frame 63 drives the limiting insert 62 to rise and disengage from the top block 61. At this time, the section steel is pushed, and the section steel can push the top block 61 to move backward, preventing the section steel from moving backward during the external straightening process and affecting the straightening effect.

[0025] A top position spring is fixedly connected to the rear side of the top position block 61. A connecting frame 611 is fixedly connected to the end of the top position spring away from the top position block 61. The connecting frame 611 is fixedly connected to the rear side of the storage compartment 41. A blocking opening 412 is opened on the inner wall of the storage compartment 411. A blocking block 612 is fixed to the top and bottom of the front side of the top position block 61. The blocking block 612 and the blocking opening 412 are at the same height.

[0026] A reciprocating striking mechanism 7 is provided at the output shaft of the drive motor 433. The reciprocating striking mechanism 7 includes a drive cam 71, a reciprocating plate 72, and a striking bar 73. The drive cam 71 is fixedly connected to the output shaft of the drive motor 433. The left side of the reciprocating plate 72 contacts the drive cam 71, and the rear side is fixedly connected to the striking bar 73. The end of the striking bar 73 away from the reciprocating plate 72 is located on the right side of the inner support column 42. During the rotation of the output shaft of the drive motor 433, the drive cam 71 will be driven to rotate. During the rotation of the drive cam 71, the reciprocating plate 72 will be pushed to move back and forth, thereby causing the reciprocating plate 72 to drive the striking bar 73 to move back and forth. During the reciprocating movement of the striking bar 73, it strikes the inner support column 42, thereby making the connection between the inner support column 42 and the steel section more compact through vibration.

[0027] A sliding bar 721 is fixedly connected to the right side of the reciprocating plate 72. The bottom end of the sliding bar 721 is slidably installed on the right side of the storage compartment 41, and a return spring is fixedly connected to the bottom end of the sliding bar 721. The end of the return spring away from the sliding bar 721 is fixedly connected to the storage compartment 41.

[0028] In this embodiment, the working principle is as follows: The steel profile is placed on the right side of the placement base plate 1, with the top of the steel profile in contact with the bottom of the support plate 52 and the bottom in contact with the limiting block 11. The forward switch of the control motor 12 is turned on, and the output shaft of the control motor 12 drives the control screw 2 to rotate. Under the action of the screw 2 and the threaded block 31, the straightening pressure rod 3 moves to the left and pushes and squeezes the steel profile for straightening. After the straightening is completed, the reverse switch of the control motor 12 is turned on, and the output shaft of the control motor 12 reverses and drives the threaded block 31 and the straightening pressure rod 3 to move to the right through the control screw 2. Then the steel profile is pushed into the storage tank 411. The switch of the drive motor 433 is turned on, and the output shaft of the drive motor 433 drives the gear 432 to rotate. The gear 432 drives the inner support column 42 to descend through the tooth groove 431 on the left side of the inner support column 42. The inner support column 42 is inserted into the steel profile and squeezes the inner protrusion inside the steel profile, so that the depression on the surface of the steel profile can be squeezed and repaired, thereby achieving complete straightening of the steel profile. Before straightening, the steel profile is shorter due to its curvature. During the straightening process, the steel profile gradually regains its length, which pushes the support plate 52 and the movable column 51 upward and compresses the support spring. During the upward movement of the movable column 51, the connecting strip 511 is driven to rise, and the connecting strip 511 drives the transmission frame 63 to rise. The transmission frame 63 drives the limiting insert 62 to rise and disengage from the top block 61. At this time, the steel profile is pushed, and the steel profile can push the top block 61 to move backward, preventing the steel profile from moving backward during the external straightening process and affecting the straightening effect. At the same time, during the rotation of the output shaft of the drive motor 433, the drive cam 71 is driven to rotate. During the rotation of the drive cam 71, the reciprocating plate 72 is driven to move back and forth, which causes the reciprocating plate 72 to drive the striking strip 73 to move back and forth. During the reciprocating movement of the striking strip 73, it strikes the inner support column 42, thereby making the connection between the inner support column 42 and the steel profile tighter through vibration.

[0029] Although embodiments of the 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 these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
