Description

Technical Field

[0001] The invention relates to a portable angle steel deformation correction tool, belonging to the technical field of angle steel correction. Background Art

[0002] Angle steel, also known as angle iron, is a long steel strip with two sides perpendicular to each other. It has two sides with equal width, and its specifications are expressed in millimeters of side width × side width × side thickness. For example, "∠30×30×3" means an equal-leg angle steel with a side width of 30 mm and a side thickness of 3 mm; angle steel can be divided into equal-leg angle steel and unequal-leg angle steel. The two sides of an equal-leg angle steel are equal in width, while an unequal-leg angle steel means that the two sides are unequal in width. In addition, angle steel can also be divided into simple-section angle steel and complex-section angle steel according to its structure. But generally speaking, angle steel mainly refers to equal-leg angle steel and unequal-leg angle steel of simple section; angle steel is mainly used to make frame structures, such as high-voltage transmission towers, bridges, beams of factory buildings, ships, and supports for mechanical equipment. In addition, angle steel is also commonly used as components, escalators, bridges, fences, etc. in construction. According to different usage requirements, angle steel can be subjected to anti-corrosion treatments such as hot-dip galvanizing or spray painting to improve its corrosion resistance and service life.

[0003] Angle steel may be deformed in various ways due to production, storage and transportation, as well as after being processed into blank parts by punching, shearing and separation. Before transferring to the next process, the process requires correction. This process is called angle steel deformation correction. There are many ways to correct angle steel deformation. The correction performed at room temperature is called cold correction, which includes mechanical correction and manual correction. If the steel is heated to a certain temperature and then corrected, it is called heating correction. According to the heating conditions, it is divided into full heating correction and local heating correction.

[0004] Angle steel is an important type of steel and is widely used in various fields. Angle steel will be compressed and deformed during transportation, and the deformed angle steel generally needs to be repaired. This deformation phenomenon is an inevitable phenomenon caused by the influence of the raw materials themselves and the requirements of the production process. The existing correction usually adopts manual hammering to correct the deformed angle steel. However, due to the relatively hard material of the angle steel, manual hammering is laborious and time-consuming, and the correction effect is not ideal. Commonly used tools and equipment are used for manual correction. Commonly used tools are various hammers, equipped with platforms, shims, etc., which can correct steels that are not large in size and not severely deformed, but will lead to high labor intensity and poor correction effect. When using correction tools for processing, the size of the angle steel will cause inconvenience in fixing, which will bring inconvenience to subsequent correction processing and reduce the convenience of using correction tools.

During the correction, the manual hydraulic drive pump delivers hydraulic oil to the hydraulic cylinder 201, so that the hydraulic cylinder 201 generates pressure to drive the top block 202 to rise, and the top block 202 lifts the deformed area to achieve rapid correction. After the angle steel 508 is inserted into the limit assembly 300, the inner angle of the angle steel 508 corresponds to the top block 202. At this time, the movable block 205 is moved upward, and then rotated. The connecting rod 206 is turned to drive the sleeve plate 207 to rotate above the top block 202, and then the movable block 205 is moved downward so that it drives the sleeve plate 207 to be sleeved on the surface of the top block 202 through the connecting rod 206.

[0045] In the present technical solution, the locking plate 301 is used to cooperate with the angle steel 508. When correcting the angle steel 508 with concave deformation on both sides, the outer corner of the angle steel 508 is placed in the upper left correction area 312 or the upper right correction area 313. At this time, the positioning component 500 is located outside the locking plate 301, and then the hydraulic cylinder 201 is started to push the two sides of the concave deformation of the angle steel 508 outward to achieve correction; when correcting the angle steel 508 with convex deformation on both sides, the outer corner of the angle steel 508 is pushed outward to achieve correction. The angle is placed in the lower left correction area 310 or in the lower left correction area 310. At this time, the positioning assembly 500 is moved and the positioning plate 506 is driven into the locking plate 301. The angle steel 508 is limited by the positioning groove 509 formed between the positioning plate 506 and the locking plate 301, and the installation and fixation of different angle steels 508 are realized according to the rotation angle to ensure a stable clamping function. Then the hydraulic cylinder 201 is started to push the convexly deformed angle steel 508 inward to realize rapid correction.

[0046] The connecting assembly 400 is composed of a connecting column 401, the two ends of which are fixedly connected to a slider 402 and a connecting member 403 respectively, the slider 402 is slidably connected to the inside of the slide groove 102 of the base 101, the connecting member 403 is a U-shaped structure, the top of the connecting member 403 is connected by a screw and a nut, and the screw connected to the connecting member 403 is slidably connected to the inside of the long hole 303, the width of the long hole 303 is the same as the diameter of the positioning hole 304, and the surface of the connecting column 401 is slidably connected to a limiting mechanism; the limiting mechanism It includes a sliding sleeve 404, which is movably connected to the surface of the connecting column 401, and the side wall of the sliding sleeve 404 is fixedly connected to two symmetrically distributed limit blocks 405, the cross-section of the limit block 405 is a U-shaped structure and a plug plate 406 is inserted inside, the plug plate 406 is a U-shaped structure and is connected to the surface of the sliding sleeve 404 through a spring 407, and the top of the plug plate 406 is fixedly connected to two symmetrically distributed fixing rods 408, the top of the fixing rod 408 is fixedly connected to the positioning column 409, and the positioning column 409 is embedded and plugged into the inside of the long hole 303.

[0047] In the present technical solution, after the angle steel 508 is installed, the slider 402 is moved inside the slide groove 102 to adjust the position of the connecting column 401, so that the limit assembly 300 is located on both sides of the angle steel 508, and the position where the angle steel 508 needs to be deformed is located between the limit assemblies 300. When adjusting according to the size of the angle steel 508, the limit assembly 300 is driven to move by the connecting piece 403 inside the long hole 303, so that the limit assembly 300 drives the correction position of the angle steel 508 to correspond to the stop block, which can be appropriately adjusted according to the width of the angle steel 508. When the adjustment is completed, the sliding sleeve 404 is moved up and the plug plate 406 is pulled to make the positioning column 409 correspond to the long hole 303, and then the plug plate 406 is released to drive the plug plate 406 to be inserted into the limit block 405 when the spring 407 is reset, and drive the fixing rod The positioning column 409 on 408 is inserted into the long hole 303. At this time, the connection piece 403 is limited by the cooperation of the fixing rod 408 and the positioning column 409, which can prevent the locking plate 301 from rotating around the screw during the correction of the angle steel 508, thereby improving the stability during the correction process; when using the right-angle head 208 to correct the inner angle of the angle steel 508, the outer corner of the angle steel 508 is placed in the upper left correction area 312, and the screw and nut on the connection piece 403 are removed, and the screw is reinserted into the positioning hole 304 to achieve connection. At this time, the locking plate 301 is rotated so that the upper left correction area 312 is located at the top. At this time, the inner corner of the angle steel 508 is facing downward, and when the hydraulic cylinder 201 is extended, it drives the right-angle head 208 to press against the inner corner of the angle steel 508 to achieve correction processing of different positions of the angle steel 508.

[0048] The positioning assembly 500 is composed of a guide sleeve 501, the cross-section of which is a U-shaped structure and is slidably connected to the surface of the track 305. One side of the guide sleeve 501 is connected to the rotating plate 505 through a pin 504; a notch 502 is opened on one side of the top of the guide sleeve 501, and the notch 502 is distributed corresponding to the limiting bolt 306. The guide sleeve 501 located in the notch 502 is threadedly connected to the positioning bolt 503, and the positioning bolt 503 is fitted and connected to the surface of the track 305; the side wall of the rotating plate 505 is fixedly connected to the positioning plate 506, and the shape of the positioning plate 506 is smaller than the lock The shape of the inner side of the tightening plate 301, the inner side of the positioning plate 506 and the locking plate 301 is formed with an L-shaped positioning groove 509 for inserting the angle steel 508, one side of the positioning plate 506 is fixedly connected to two symmetrically distributed guide plates 507, the bottom end of the positioning plate 506 is an arc structure and contacts the surface of the angle steel 508, and when the positioning plate 506 is located inside the locking plate 301, the rotating plate 505 and the guide plate 507 are respectively located on both sides of the locking plate 301, the guide plate 507 is distributed correspondingly to the movable stop block 308, and the inner wall of the guide plate 507 is an inclined structure and is distributed correspondingly to the movable stop block 308.

[0049] In the present technical scheme, when the angle steel 508 is corrected in the lower left correction area 310 and the lower right correction area 311, the guide sleeve 501 is moved from one side of the track 305, so that the notch 502 of the guide sleeve 501 is moved away from the limit bolt 306, and the rotating plate 505 and the positioning plate 506 are driven to move to the locking plate 301, and the rotating plate 505 is rotated around the pin shaft 504 so that it drives the positioning plate 506 to rotate and move to the inside of the locking plate 301. At this time, the bottom end of the positioning plate 506 contacts the inner wall of the angle steel 508, and the positioning plate 506 is pushed so that its side end rests against the inner wall of the other side of the angle steel 508, thereby achieving the fixation of the angle steel 508, and then tightening the positioning bolt 503 to achieve the fixation of the guide sleeve 501 above the track 305. The bottom end of the positioning plate 506 cannot be completely rotated to the vertical position due to the thickness of the angle steel 508. At this time, the positioning plate 506 tends to the vertical position, and the movable stop block 308 is moved downward to separate the magnet 309 on the movable stop block 308 from the locking plate 301.
