DETAILED DESCRIPTION
[0014] The following will be combined with the accompanying drawings of the utility model to clearly and completely describe the technical solution of the utility model. It is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the utility model. In the description of the utility model, it should be noted that the terms "upper", "lower", "inside", "outside" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when used, which is only for the convenience of describing the utility model or simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.
[0015] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0016] See also Figure 1 to Figure 3 The utility model is an adjustable cutting device for steel bars, comprising a horizontal band saw body, wherein the bottom four corners of the horizontal band saw body are supported by hydraulic lifting columns 12. Furthermore, the bottom four corners of the horizontal band saw body in the utility model are connected and supported by four hydraulic lifting columns, and the four hydraulic lifting columns adopt the same hydraulic system to control the synchronous lifting action. A bar roller table composed of a plurality of rollers 8 arranged at intervals is arranged below the horizontal band saw body, and a bar clamping mechanism is also arranged directly below the horizontal band saw body, and the bar clamping mechanism includes a fixed clamping plate 3 and a movable clamping plate 5. Further The bottom of the fixed splint in the utility model is provided with a support seat 11, and the back of the movable splint is provided with a triangular reinforcing rib plate 9. The two are arranged relatively and are both placed in the gap between the bar rollers directly below the horizontal band saw body. The fixed splint and the movable splint both extend upward from the top surface of the bar roller. A cutting slit 13 is provided between the fixed splint and the movable splint for the annular saw blade in the horizontal band saw body to pass through. A sliding platform 10 is provided at the bottom of the movable splint, and a clamping cylinder 7 is installed on the sliding platform. The front end of the piston rod of the clamping cylinder is connected to the movable splint and drives the movable splint to move on the sliding platform.
[0017] Furthermore, the horizontal band saw body described in the utility model comprises a housing 6, an electric saw motor 1 and an annular saw blade 4, and a saw blade limiting clamp plate 2 is arranged downward on the housing, and the saw blade limiting clamp plate limits the annular saw blade portion passing through the fixed clamp plate and the movable clamp plate. Furthermore, the saw blade limiting clamp plate described in the utility model is composed of two clamping plates, and the annular saw blade passes through the gap between the two clamping plates.
[0018] As a practical tool, the utility model first adjusts the height of the entire horizontal band saw body to a suitable position according to the specific size of the steel bar to be cut before actual cutting, and then places the steel bar to be cut between the fixed clamping plate and the movable clamping plate, and starts the clamping cylinder to push the movable clamping plate forward to clamp the steel bar tightly, and then the electric saw motor can be started, and the circular saw blade continuously cuts the steel bar. While cutting, four hydraulic lifting columns use the same set of hydraulic system to control the synchronous lifting action, and together control the slow descent to cut until the entire steel bar is cut off.
[0019] After the steel bar is cut, the clamping cylinder is loosened and retreated, and the cut bar is transported out through the roller, and the following bar continues to be pushed forward, and the action is repeated to cut. The clamping and tightening of the bar and the lifting and lowering of the ring saw blade in the utility model are all automatically controlled actions, which greatly improves the work efficiency and reduces the burden and labor intensity of the staff.
