Technical Field

[0001] The utility model relates to the technical field of steel bar shearing devices, in particular to an adjustable length device for assisting in shearing steel bars. Background Art

[0002] Generally, there are a large number of steel bars that need to be sheared and processed on construction sites. Generally, automated steel bar shearing and processing machines are available at larger construction sites in cities. Currently, rapid changes are also taking place in rural areas. Most rural families are successively demolishing old houses and building new ones, so there are also problems of steel bar shearing and processing during house construction.

[0003] Due to the high price of automated steel bar shearing equipment, it is difficult to see mechanized steel bar shearing and processing equipment on rural construction sites. Most of them are manual shearing devices. These existing manual steel bar shearing devices at least have the following defects: they do not have an auxiliary mechanism for length measurement and can only be measured by an external tape measure. When it is necessary to shear multiple steel bars of the same length, each shear requires re-measurement or measurement against the sheared steel bar before shearing, which is very troublesome. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides an adjustable length device for assisting in shearing steel bars.

[0027] The following will detail the technical solutions of the present utility model in conjunction with the drawings and embodiments.

[0028] Please refer to Figures 1 to 5 As shown in FIGS. 1 to 5, the embodiment of the present application provides an adjustable length device for assisting in shearing reinforcing bars, including:

[0029] A base 1;

[0030] A shearing mechanism 2, provided on the base 1, for shearing the reinforcing bar 100:

[0031] The length adjustment plate 3 is movably arranged on the base 1 and can move along the length direction of the base 1 to adjust the distance from the shearing mechanism 2. The steel bar 100 extends into the shearing mechanism 2 and one end abuts against the length adjustment plate 3.

[0032] Among them, the distance between the length adjustment plate 3 and the shearing mechanism 2 is adjusted to change the shearing length of the steel bar 100.

[0033] When it is necessary to shear the steel bars 100 of the same length multiple times, only need to move and adjust the position of the length adjustment plate 3 to adjust the distance between the length adjustment plate 3 and the shearing mechanism 2 to the required length. Then extend the steel bar 100 into the shearing mechanism 2 and one end abuts against the length adjustment plate 3, and the length measurement is completed. Then repeat the shearing, without the need to measure the length and measure the steel bar every time, which is practical and convenient.

[0034] Further, a vertical plate 4 is also arranged on the base 1 along its length direction. A length adjustment groove 40 extending along its length direction is opened on the vertical plate 4. One side of the length adjustment plate 3 protrudes outward with an adjustment slider 30 that can be embedded in the length adjustment groove 40 and slide.

[0035] Further, a fixing structure 5 is also arranged between the adjustment slider 30 and the vertical plate 4 for fixing the relative position between the two.

[0036] Specifically, the fixing structure 5 includes a limiting plate 51 arranged at one end of the adjustment slider 30. A plurality of threaded holes 52 are opened on the limiting plate 51. Fixing screws 53 are correspondingly screwed on the threaded holes 52. Among them, the fixing screws 53 are screwed to press against the vertical plate 4 to fix the relative position between the length adjustment plate 3 and the vertical plate 4.

[0037] When adjustment is needed, only need to loosen the fixing screws 53 by screwing, and then move the length adjustment plate 3 to the corresponding position, and then tighten the fixing screws 53, which is practical and convenient.

[0038] Further, scale lines 61 extending along the length direction of the base 1 are also arranged on the vertical plate 4. An indicating mark 62 pointing to the scale lines 61 is also arranged on the adjustment slider 30. By the cooperation of the indicating mark 62 and the scale lines 61 for reading, it is more convenient and accurate to adjust the position of the length adjustment plate 3, which is practical and convenient.

[0039] Further, the shearing mechanism 2 includes a shearing part 21 arranged on the base 1 and on one side of the vertical plate 4, and a shearing piece 22 hinged on one side of the shearing part 21. Fixed shearing groove groups 23 and rotating shearing groove groups 24 are respectively arranged between the shearing part 21 and the shearing piece 22.

[0040] Specifically, the fixed shearing groove group 23 includes a first shearing groove A231, a second shearing groove A232, and a third shearing groove A233 arranged along the circumferential side of the shearing part 21. The rotating shearing groove group 24 includes a first shearing groove B241, a second shearing groove B242, and a third shearing groove B243 arranged along the circumferential side of the shearing member 22. Among them, the first shearing groove A231 corresponds to the first shearing groove B241, the second shearing groove A232 corresponds to the second shearing groove B242, and the third shearing groove A233 corresponds to the third shearing groove B243.

[0041] During shearing, rotate the shearing member 22 to align the respective shearing grooves of the fixed shearing groove group 23 and the rotating shearing groove group 24. Then, according to the size specification of the steel bar 100, insert the steel bar 100 into the corresponding shearing groove and abut one end against the length adjusting plate 3. Next, rotate the shearing member 22 to stagger the shearing grooves on the fixed shearing groove group 23 and the rotating shearing groove group 24, so that the steel bar 100 breaks due to the reverse force at the connection point of the fixed shearing groove group 23 and the rotating shearing groove group 24, thus completing the shearing, which is practical and convenient.

[0042] Specifically, the groove widths of the first shearing groove A231, the second shearing groove A232, and the third shearing groove A233 are sequentially increased. This is to accommodate steel bars 100 of multiple different specifications, which is practical and convenient.

[0043] Furthermore, a collection area 7 for collecting the steel bars 100 is also provided on the base 1 between the shearing mechanism 2 and the vertical plate 4. The steel bars 100 are collected through the collection area 7 to prevent them from falling randomly after shearing, which is practical and convenient.
