Description

Technical Field

[0001] The utility model belongs to the technical field of H-shaped steel production, and specifically relates to a flying saw dragging chain buffer mechanism of an H-shaped steel production line. Background Art

[0002] In the production process of H-shaped steel, the flying saw is a key cutting equipment, which is used to accurately cut the H-shaped steel according to the predetermined length. The drag chain of the flying saw plays the role of transmitting power and keeping the flying saw stable during the flying saw cutting process. Therefore, we need a flying saw drag chain buffer mechanism for the H-shaped steel production line;

[0003] However, during the production process, the chain reciprocates. Due to the large size of the saw body and the frequent reciprocating motion, the chain is subjected to a large impact force during the reciprocating motion, which causes the chain to have a relatively concentrated stress during use, which can easily lead to chain breakage, thus affecting production. In addition, replacing the chain will result in high expenses, greatly increasing production costs.

[0004] In order to solve the above problems, the present application proposes a flying saw dragging chain buffer mechanism for an H-shaped steel production line. Utility Model Content

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A flying saw dragging chain buffer mechanism for an H-shaped steel production line comprises a device body, an outer side wall of the device body is fixedly connected with a mounting box, and an inner side wall of the mounting box is provided with a flying saw body;

By arranging the sliding column, the mounting seat and the pulley, it is convenient to reduce the friction between the lever structure and the flying saw body, thereby reducing the loss of the flying saw body.

[0012] Preferably, a support spring is wound around the outer side wall of the slide column, and the outer side wall of the support spring does not contact the outer side wall of the slide column. By providing the support spring, it is convenient to support the mounting seat and the pulley, thereby providing a certain supporting force for the flying saw body.

[0015] Preferably, a supporting foot is fixedly connected to the bottom of the mounting plate, and the bottom of the supporting foot is provided with an inclination angle. By providing the supporting foot, the mounting plate is easily supported.

[0016] To sum up, the technical effects and advantages of the utility model are as follows: the flying saw of the H-shaped steel production line drags the chain buffer mechanism, through the coordinated use of a slider, a moving block, an extrusion spring, a first slide bar, a column, a lever cross bar, a second slide groove, a second slide bar, a positioning plate, and a positioning rod, which is convenient for reducing the impact force caused by the frequent reciprocating movement of the steel saw on the chain, reduces the wear of the chain, and avoids the chain from breaking during use, thereby reducing the cost of replacing the chain.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Reference Figure 1-3 , a flying saw dragging chain buffer mechanism for an H-shaped steel production line, comprising a device body 1, an outer side wall of the device body 1 is fixedly connected with a mounting box 2, and an inner side wall of the mounting box 2 is provided with a flying saw body 3;

[0031] The outer side wall of the installation box 2 is provided with a lever structure 4;

[0032] A bearing structure 5 is provided at one end of the lever structure 4;

[0033] The lever structure 4 includes a mounting plate 401 fixedly connected to the outer wall of the mounting box 2, a first slide groove 402 is provided through the top of the mounting plate 401, a square plate 403 is fixedly connected to the inner wall of the mounting plate 401, two square plates 403 are provided, and the two square plates 403 are respectively located at the two ends of the first slide groove 402, and the outer walls of the two square plates 403 are fixedly connected with a first slide rod 408, the first slide rod 408 is located inside the first slide groove 402, and the outer wall of the first slide rod 408 is slidably connected with a slider 405, and the slider 405 can rotate or slide along the first slide rod 408, and the top of the slider 405 is fixedly connected with a column 409, and the column 409 is located at the top center of the slider 405, and the outer wall of the column 409 is slidably connected with a moving block 406, and the top of the slider 405 is fixed A compression spring 407 is fixedly connected, and the compression spring 407 is located outside the column 409. The outer side wall of the moving block 406 is rotatably connected to the lever cross bar 410. A second slide groove 411 is opened through the top of the mounting plate 401. The mounting plate 401 is fixedly connected to the second slide bar 412 through the second slide groove 411. The second slide bar 412 is located inside the second slide groove 411. The outer side wall of the second slide bar 412 is slidably connected to a positioning plate 413. The bottom of the positioning plate 413 is set to be square, and the bottom outer side wall of the positioning plate 413 is adapted to the inner side wall of the second slide groove 411, so as to avoid the positioning plate 413 from changing its angle with the mounting plate 401 during the sliding process. The outer side wall of the positioning plate 413 is fixedly connected to a positioning rod 414, and the outer side wall of the positioning rod 414 is rotatably connected to the outer side wall of the lever cross bar 410.

[0034] When in use, when the device body 1 is in operation, the equipment on the device body 1 will drive the flying saw body 3 to move. At this time, the outer wall of the flying saw body 3 contacts the outer wall of the lever cross bar 410, thereby driving the slider 405 to rotate along the first slider 408. When the flying saw body 3 is bent under force, the flying saw body 3 will squeeze the end of the lever cross bar 410 away from the slider 405, so that the lever cross bar 410 rotates along the positioning rod 414, thereby causing the moving block 406 to slide up and down along the column 409. Because the bottom of the moving block 406 is fixedly connected to the squeezing spring 407, and the bottom of the squeezing spring 407 is fixedly connected to the top of the slider 405, when the lever cross bar 410 is rotated under force, the squeezing spring 407 pulls the moving block 406 to limit the rotation angle of the lever cross bar 410, and then uses the lever principle to support the flying saw body 3, so as to avoid excessive impact force on the flying saw body 3 during use, thereby preventing the flying saw body 3 from breaking during use.

[0035] Reference Figure 3 and Figure 4The bearing structure 5 includes a bearing plate 501 fixedly connected to one end of the lever cross bar 410, the bearing plate 501 is located at the end of the lever cross bar 410 away from the slider 405, and the bearing plate 501 is located at the outer wall of the flying saw body 3, the inner wall of the bearing plate 501 is slidably connected with a sliding column 503, the top of the sliding column 503 is fixedly connected with a mounting seat 504, the mounting seat 504 is located at the top of the bearing plate 501, the inner wall of the mounting seat 504 is rotatably connected with a pulley 505, the outer wall of the pulley 505 is in contact with the outer wall of the flying saw body 3, and the pulley 505 is made of rubber, which can effectively reduce the wear of the pulley 505 on the outer wall of the flying saw body 3.

[0036] Reference Figure 4 The outer wall of the sliding column 503 is wrapped with a support spring 506, and the support spring 506 is located at the bottom of the bearing plate 501. The outer wall of the support spring 506 does not contact the outer wall of the sliding column 503. When the outer wall of the flying saw body 3 collides with the outer wall of the pulley 505, the pulley 505 is forced to move downward, thereby pushing the sliding column 503 to pull the support spring 506. At this time, the pulley 505 is supported by the elastic force of the support spring 506 itself, reducing the collision force between the outer wall of the flying saw body 3 and the outer wall of the pulley 505.

[0037] Reference Figure 4 A groove 502 is provided at the top of the supporting plate 501, and the groove 502 is located at the center of the supporting plate 501. The groove 502 is located below the mounting seat 504, and the inner wall of the groove 502 is adapted to the outer wall of the mounting seat 504, thereby extending the moving distance of the mounting seat 504 and reducing the impact force between the flying saw body 3 and the pulley 505.

[0038] Reference Figure 1 The outer wall of the square plate 403 is fixedly connected with a connecting spring 404, and four connecting springs 404 are provided. There are three sliders 405, moving blocks 406, extrusion springs 407, columns 409, lever cross bars 410, positioning rods 414, and positioning plates 413. The four connecting springs 404 are distributed between the three sliders 405 and the two square plates 403. Since the flying saw body 3 will move during use, when the outer wall of the flying saw body 3 collides with the outer wall of the first lever cross bar 410, one of the connecting springs 404 is stretched by force, so that the flying saw body 3 can drive the lever cross bar 410 to move at the same time, so that the lever structure 4 can continue to support the flying saw body 3, thereby continuously alleviating the impact force on the flying saw body 3.

[0039] Reference Figure 1The bottom of the mounting plate 401 is fixedly connected with a supporting foot 6, and there are four supporting feet 6. The bottoms of the four supporting feet 6 are all provided with an inclination angle. The four supporting feet 6 support the mounting plate 401 to avoid the mounting plate 401 from breaking during use, thereby improving the stability of the equipment.

[0040] Working principle: during use, when the device body 1 is in operation, the equipment on the device body 1 will drive the flying saw body 3 to move. At this time, the outer wall of the flying saw body 3 contacts the outer wall of the lever cross bar 410, thereby driving the slider 405 to rotate along the first slider 408. When the flying saw body 3 is bent under force, the flying saw body 3 will squeeze the end of the lever cross bar 410 away from the slider 405, so that the lever cross bar 410 rotates along the positioning rod 414, thereby making the moving block 406 slide up and down along the column 409. Because the bottom of the moving block 406 is fixedly connected to the squeezing spring 407, and the bottom of the squeezing spring 407 is fixedly connected to the top of the slider 405, when the lever cross bar 410 is rotated under force, the squeezing spring 407 pulls the moving block 406 to limit the rotation angle of the lever cross bar 410, and then uses the lever principle to support the flying saw body 3, so as to avoid excessive impact force on the flying saw body 3 during use, thereby preventing the flying saw body 3 from breaking during use;

[0041] There are three sliders 405, moving blocks 406, extrusion springs 407, columns 409, lever cross bars 410, positioning rods 414, and positioning plates 413. The four connecting springs 404 are respectively located between the three sliders 405 and the two square plates 403. Since the flying saw body 3 will move during use, when the outer wall of the flying saw body 3 collides with the outer wall of the first lever cross bar 410, one of the connecting springs 404 is stretched by force, so that the flying saw body 3 can drive the lever cross bar 410 to move at the same time, so that the lever structure 4 can continue to support the flying saw body 3, thereby continuously alleviating the impact force on the flying saw body 3.
