Description

Technical Field

[0001] The utility model relates to the technical field of steel frame correction, in particular to a steel frame correction machine for steel structure processing. Background Art

[0002] The steel frame structure is a multi-layer and multi-span steel frame composed of beams and columns, which is used to bear vertical and horizontal loads. Under the action of horizontal loads, this structure has both overall lateral displacement as a cantilever beam and local lateral displacement caused by interlayer shear force, resulting in large deformation. The manufacturing process of the steel frame structure is usually steel plate cutting, assembly, welding, and correction, which are completed in turn on cutting machines, assembly machines, gantry submerged arc welding, correction machines and other equipment. During the welding process, the steel frame structure will cause warping deformation, so it is necessary to reduce the warping deformation and correct it.

[0003] The patent specification with announcement number CN215699319U discloses a correction device for welding of large steel frames, wherein a vertical plate is arranged at the bottom of the frame, a welding fixing plate is arranged at the inner side of the vertical plate, a first telescopic rod is arranged at the welding fixing plate, a support plate is arranged at the top of the welding fixing plate, and a second telescopic rod is arranged at the support plate; the utility model has a welding fixing plate arranged at the inner side of the vertical plate, and a first telescopic rod is arranged at the outer side of the welding fixing plate, a support plate is arranged at the top of the welding fixing plate, and a second telescopic rod is arranged at the outer side of the support plate. Before welding the large steel frame, the steel frame to be welded is placed on the welding fixing plate, and the steel frame is placed between the two welding fixing plates by adjusting the telescopic lengths of the first telescopic rod and the second telescopic rod.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: the above device is not convenient for accurate correction of the steel frame during use, because some structures are difficult to identify with the naked eye, so the corrected steel frame in this case will have a low yield rate and inaccurate structural stress, which may cause accidents. Therefore, further improvement is needed. Utility Model Content

[0005] The utility model provides a steel frame straightening machine for steel structure processing, which solves the problem in the related art that it is inconvenient to perform accurate straightening on the steel frame.

[0006] The technical solution of the utility model is as follows:

[0007] The outer end of the hydraulic cylinder is connected with the hydraulic cylinder to the upper and lower ends of the hydraulic cylinder to form a circular arc structure, and the circular arc structure has the shape of a back-moving wheel, a center of gravity of the back-moving wheel and a center of gravity of the back-moving wheel.

[0008] Preferably, the outer surface of the rod body is in contact with the inside of the side plate, and the rotating plate and the housing are movably connected via a rotating shaft.

[0009] Preferably, the reciprocating screw rod is connected to the base plate via a bearing, and a limiting rod is fixedly connected to the bottom of the bearing seat.

[0010] Preferably, a limiting groove is provided on one side of the interior of the bottom plate, and the limiting rod extends into the limiting groove and contacts therewith.

[0011] Preferably, the spring is in an unstretched deformed state, and the rotating plate is inclined toward the inside of the housing.

[0015] The working principle and beneficial effects of the utility model are:

[0016] 1. In the utility model, after the steel frame is corrected, the steel frame will drive the rotating plate to rotate as it enters the interior of the jamming shell. During the rotation, the rotating plate will simultaneously drive the spring to perform compression work. If the steel frame is corrected successfully, the rotating plate will be in a "straight line" with the jamming shell to facilitate the success of the correction and facilitate judgment.

[0017] 2. In the utility model, if part of the steel frame is not precisely flush during the correction process, the push plate will push the steel frame to continue to move toward the inside of the jamming shell. During this process, the rotating plate will contact the switch, and then the switch will control the buzzer to turn on. After the buzzer is turned on, it will sound an alarm and the motor will stop working, so that the staff can perform subsequent correction operations. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0025] Example 1

[0026] like Figure 1~Figure 4As shown, this embodiment proposes a steel frame straightening machine for steel structure processing, including a base plate 1, a side plate 2 is fixedly connected to the top side of the base plate 1, a hydraulic cylinder 3 is fixedly connected to the outer side of the side plate 2, a rod body 4 is slidably connected inside the hydraulic cylinder 3, a shell 5 is fixedly connected to the outer end of the rod body 4, a guide plate 6 is fixedly connected to the outer side of the shell 5, a roller 7 is movably connected to the shell 5 through a rotating shaft, a card shell 8 is fixedly connected to the top of the base plate 1, a mounting plate 9 is fixedly installed on the outer side of the card shell 8, a fixed plate 10 is fixedly connected to the outer side of the mounting plate 9, a rotating plate 12 is fixedly connected to one side of the fixed plate 10, a spring 11 is fixedly connected to the outer end of the rotating plate 12, a motor 15 is fixedly connected to the outer side of the base plate 1, a reciprocating screw 16 is fixedly connected to the motor 15 through an output shaft, a bearing seat 17 is arranged on the outside of the reciprocating screw 16, the bearing seat 17 and the reciprocating screw 16 are connected by a ball nut pair, a clamping rod 19 is fixedly connected to the outer side of the bearing seat 17, and a push plate 20 is fixedly connected to one end of the clamping rod 19.

[0027] In this embodiment, the outer surface of the rod body 4 is in contact with the inside of the side plate 2 , and the rotating plate 12 and the clamping shell 8 are movably connected via a rotating shaft, which can facilitate the sliding operation of the rod body 4 .

[0028] In this embodiment, the reciprocating screw 16 is connected to the base plate 1 via a bearing, and a limit rod 18 is fixedly connected to the bottom of the bearing seat 17 to facilitate the rotation and support of the reciprocating screw 16.

[0029] In this embodiment, a limiting groove is provided on one side of the interior of the bottom plate 1 , and the limiting rod 18 extends into the limiting groove and contacts therewith, which can facilitate the limiting work of the limiting rod 18 .

[0030] In this embodiment, the spring 11 is in an unstretched deformed state, and the rotating plate 12 is inclined toward the inside of the housing 8, which can facilitate the rotation of the rotating plate 12.

[0031] In this embodiment, the edges of the guide plate 6 and the roller 7 are in the same plane, and the cross section of the guide plate 6 is set to be in a Z shape, which can facilitate the guide plate 6 and the roller 7 to guide and correct the steel frame.

[0032] When the staff needs to correct the steel frame, first the staff needs to place the steel frame into one side of the card shell 8, and then the staff turns on the hydraulic cylinder 3. After turning on the hydraulic cylinder 3, it will synchronously drive the rod body 4 to stretch. During the stretching process, the rod body 4 will synchronously drive the shell 5 and the guide plate 6 to move. During the movement, the guide plate 6 will synchronously drive the roller 7 to move. At this time, the guide plate 6 and the roller 7 will push the steel frame laterally and correct it. Then the staff turns on the motor 15. After turning on, the motor 15 will synchronously drive the reciprocating screw rod 16 to rotate. During the rotation, the reciprocating screw rod 16 will synchronously drive the bearing seat 17 to reciprocate and move laterally. During the movement, the bearing seat 17 will synchronously drive the card rod 19 to move. During the movement, the card rod 19 will synchronously drive the push plate 20 to move. During the movement, the push plate 20 will synchronously drive the steel frame to push.

[0033] Since the guide plate 6 and the roller 7 can correct the steel frame under the action of the hydraulic cylinder 3 and the rod body 4, when the steel frame is corrected, the steel frame will drive the rotating plate 12 to guide and rotate when entering the interior of the jammer 8. During the rotation, the rotating plate 12 will simultaneously drive the spring 11 to perform compression work. If the steel frame is successfully corrected, the rotating plate 12 will be in a "straight line" with the jammer 8 to facilitate the success of the correction and facilitate judgment.

[0034] Example 2

[0035] like Figure 2~Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a switch 13 is fixedly connected to one side of the mounting plate 9, and a buzzer 14 is fixedly connected to the top of the housing 8, which can facilitate the fixing of the switch 13.

[0036] In this embodiment, the buzzer 14 is electrically connected to the switch 13, and the motor 15 is also electrically connected to the switch 13, so that the switch 13 can control both of them.

[0037] In the above work, a qualified steel frame will not drive the rotating plate 12 to contact the switch 13. If the steel frame is not accurately flush in some positions during the correction process, the push plate 20 will push the steel frame to continue to move toward the inside of the jamming shell 8. During this process, the rotating plate 12 will contact the switch 13, and then the switch 13 will control the buzzer 14 to turn on. After being turned on, the buzzer 14 will sound an alarm and the motor 15 will stop working, so that the staff can perform subsequent correction operations again to prevent the problem of inaccurate correction results causing a decrease in yield.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
