Description

Technical Field

[0001] The utility model relates to the technical field of threaded steel production, in particular to a shearing device for threaded steel production. Background Art

[0002] Rebar is a hot-rolled ribbed steel bar. There are two common classification methods for rebar, one is classification by geometric shape, the other is classification by performance. Before construction, the rebar needs to be cut to the corresponding length according to the size design so that it can be used in time during construction.

[0003] A Chinese patent document with application number CN202223205287.0 in the related art proposes a steel bar shearing machine, which is used by installing a distance positioning channel steel at the shearing opening of the shearing machine body, and having scale lines engraved in the distance positioning channel steel. After the positioning plate is moved to the scale line of the required length, the fastening bolt is rotated and tightened. The fastening bolt is rotated and moved to squeeze the square plate, so that the square plate moves along the inner wall of the positioning seat and drives the pressure block to fit tightly with the inner wall of the square groove. When the square plate moves, the tension spring is in a stretched state, and the pressure block fits tightly with the inner wall of the square groove to fix the positioning plate. The steel bar is passed through the shearing opening of the shearing machine body and the end of the steel bar is pressed against the positioning plate to shear the steel bar. After shearing by the shearing machine body, the steel bar of the required length is obtained, and the sheared steel bar can be taken out from the distance positioning channel steel.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: However, the length of the distance positioning channel steel is still fixed. When it is necessary to measure a longer threaded steel bar, it is necessary to replace a longer distance positioning channel steel to measure the threaded steel bar, which is inconvenient to operate. When transporting the shearing machine body, even if the distance positioning channel steel can be disassembled from the shearing machine body for transportation, it is still inconvenient to transport and use due to the overall length of the distance positioning channel steel. In view of this, a shearing device for threaded steel production is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in 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 in 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.

[0022] See also Figure 1-5 A shearing device for threaded steel production in this embodiment includes a shearing machine body 1, a first distance positioning channel steel 2 is arranged on one side of the shearing machine body 1, the first distance positioning channel steel 2 is detachably connected to the shearing machine body 1, a positioning component 4 is arranged on the first distance positioning channel steel 2, a splicing mechanism 5 is arranged on the first distance positioning channel steel 2, and a second distance positioning channel steel 3 is arranged on the first distance positioning channel steel 2.

[0023] The splicing mechanism 5 includes a fixed plate 501 and a limiting groove 506. The fixed plate 501 is fixed to one end of the first distance positioning channel steel 2. A rotatable rotating rod 502 is fixed in the fixed plate 501. A rotating disk 507 is fixed on the rotating rod 502. Pull ropes 508 are wound around both sides of the rotating disk 507.

[0024] Two first mounting plates 509 are fixed in the inner cavity of the fixed plate 501, and two second mounting plates 512 are slidably installed in the inner cavity of the fixed plate 501. A telescopic rod 510 is fixed between the first mounting plate 509 and the second mounting plate 512, and a spring 511 is sleeved on the telescopic rod 510. The spring 511 is a compression spring 511, which is a spiral spring 511 that withstands forward pressure. The cross-section of the material used is mostly circular, and there is a certain gap between the circles of the compression spring 511. When subjected to external load, the spring 511 shrinks and deforms to store deformation energy. A moving block 503 is fixed on the second mounting plate 512, and a limiting groove 506 that is engaged with the moving block 503 is opened in the second positioning channel steel.

[0025] The device rotates the rotating rod 502, which drives the rotating disk 507 to rotate. The rotating disk 507 then pulls the pull ropes 508 on both sides. The pull ropes 508 drive the second mounting plate 512 to move. The second mounting plate 512 squeezes the spring 511, and the second mounting plate 512 drives the moving block 503 to move outside the limiting groove 506, so that the first distance positioning channel steel 2 and the second distance positioning channel steel 3 can be disassembled.

[0026] The two first mounting plates 509 and the second mounting plate 512 are respectively located on both sides of the turntable 507 , and one side of the pull rope 508 is fixed to one side of the second mounting plate 512 , so that the turntable 507 can pull the second mounting plate 512 to move.

[0027] At the same time, the splicing mechanism 5 includes a groove 504 and a long groove 505. A groove 504 that is engaged with the fixed plate 501 is provided on one side of the second distance positioning channel steel 3. A long groove 505 is provided on the second distance positioning channel steel 3. The rotating rod 502 is slidably connected to the long groove 505. A through hole is provided on the fixed plate 501. The rotating rod 502 is rotatably connected to the through hole, and passes through the through hole and extends to the fixed plate 501. When the fixed plate 501 is inserted into the groove 504, the rotating rod 502 can slide in the long groove 505, which makes it convenient for subsequent staff to rotate the rotating rod 502.

[0028] The working principle of the above embodiment is:

[0029] When it is necessary to splice the first distance positioning channel steel 2 and the second distance positioning channel steel 3, the turntable 507 is driven to rotate by rotating the rotating rod 502, and then the pull ropes 508 on both sides are pulled by the turntable 507, and the pull ropes 508 drive the second mounting plate 512 to move, and then the second mounting plate 512 squeezes the spring 511, and then the second mounting plate 512 drives the moving block 503 to move outside the limiting groove 506, so that the first distance positioning channel steel 2 and the second distance positioning channel steel 3 can be disassembled.

[0030] On the contrary, when the second distance positioning channel steel 3 needs to be installed, the movable block 503 on the second mounting plate 512 is driven to move into the limiting groove 506 by the elasticity of the spring 511, so that the second distance positioning channel steel 3 can be limited and fixed. In this way, multiple distance positioning channel steels can be quickly spliced, and then it is suitable for shearing longer threaded steel bars.
