Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel corner cutting technology, and in particular to a cutting device for the edges and corners of building steel. Background Technology
[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The various components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Steel structures are prone to corrosion; generally, steel structures require rust removal, galvanizing, or painting, and regular maintenance.
[0003] When assembling and welding steel structures, it is necessary to cut off the corners of the steel structure. In some specific situations, it is necessary to limit the cutting angle. The traditional method requires using tools to measure and mark the cutting angle, and then using cutting tools to cut. However, this method is cumbersome, and the measurement and marking takes a certain amount of time, resulting in low operating efficiency. Based on this, a steel corner cutting device for building materials is proposed to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a cutting device for the corners of building steel, which effectively solves the deficiencies of the prior art.
[0005] To achieve the above objectives, one embodiment of this utility model provides a steel corner cutting device, including a support frame. A vertically placed mounting rod is installed on one side of the top surface of the support frame. A rotating frame is rotatably installed on one side of the bottom end of the mounting rod, and two tension springs are installed between the middle part of the rotating frame and the top end of the mounting rod. A cutting saw body is installed in the middle of the rotating frame. A steel placement frame capable of circular rotation is installed in the middle of the top surface of the support frame. An angle ruler is installed on the support frame near the rotation center of the steel placement frame, and a pointer is installed on the side of the steel placement frame near its rotation center.
[0006] Preferably, one side of the bottom surface of the support frame is threaded with a lead screw, one end of which is equipped with a handwheel, and the other end of which abuts against the steel placement frame. This design facilitates the relative rotation between the lead screw and the support frame by rotating the handwheel, thereby pushing the rotation position of the steel placement frame, increasing the friction between the two, and locking the position of the steel placement frame.
[0007] Preferably, the top of the rotating frame is equipped with a control handle, and the top of the handle is tilted upwards. This design provides a gripping position for the user, and a protective cover is added to the top of the control handle to improve comfort during operation.
[0008] Preferably, in any of the above solutions, the steel placement rack is recessed downwards near its rotation center, and a gap is left between the bottom surface of the steel placement rack and the angle ruler. This solution allows for the saw blade of the cutting saw body to have room to move, facilitating the bevel cutting of the steel. At the same time, a safe distance is maintained between the bottom surface of the steel placement rack and the angle ruler to avoid motion interference between the two.
[0009] Preferably, in any of the above solutions, multiple limiting blocks are installed on both sides of the top surface of the steel placement rack, and the four limiting blocks on one side are threaded with fastening bolts. This solution facilitates the clamping of the steel inside the steel placement rack by rotating the locking bolts, thus preventing the steel from shaking during the cutting process.
[0010] Preferably, one of the above solutions is that the steel placement rack is equipped with two support rollers at the end away from the pointer. This solution facilitates the support of the suspended position of the steel placement rack and allows the steel to be placed horizontally on the top surface of the steel placement rack.
[0011] This utility model has the following advantages:
[0012] 1. This steel corner cutting device for construction uses a support frame with a steel placement rack rotatably mounted on the center of its top surface. An angle gauge is also installed on the center of the top surface of the support frame, while a pointer is installed on one side of the steel placement rack. This causes the steel placement rack to rotate, with the pointer pointing to the angle gauge for easy measurement of the rotation angle. Simultaneously, the rotating frame is rotated by pulling a control handle, causing the cutting saw body to cut the steel. The overall structure is simple and easy to operate, thus achieving the purpose of cutting steel corners at a certain angle.
[0013] 2. The steel corner cutting device for construction uses a lead screw and a handwheel. The lead screw is threaded to the middle of the support frame. Rotating the handwheel causes one end of the lead screw to push the steel placement frame to a rotating position, thus locking the position of the steel placement frame. The steel placement frame has two support rollers installed at one end, which facilitates support for the suspended position of the steel placement frame and allows the steel to be placed horizontally on the top surface of the steel placement frame.

[0019] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.
[0020] like Figures 1 to 4 As shown, a steel edge cutting device for construction includes a support frame 1. A vertically placed mounting rod 3 is installed on one side of the top surface of the support frame 1. A rotating frame 2 is rotatably installed on one side of the bottom end of the mounting rod 3, and two tension springs 5 are installed between the middle part of the rotating frame 2 and the top end of the mounting rod 3. A cutting saw body 4 is installed in the middle of the rotating frame 2. A steel placement frame 11 that can rotate in a circle is installed in the middle of the top surface of the support frame 1. An angle ruler 6 is installed on the support frame 1 near the rotation center of the steel placement frame 11. A pointer 12 is installed on the side of the steel placement frame 11 near its rotation center.
[0021] A lead screw 13 is threadedly connected to one side of the bottom surface of the support frame 1. A handwheel 14 is installed at one end of the lead screw 13, and the other end abuts against the steel placement rack 11. As an optional technical solution of this utility model, this facilitates the relative rotation between the lead screw 13 and the support frame 1 by rotating the handwheel 14, thereby pushing the rotation position of the steel placement rack 11, increasing the friction between the two, and locking the position of the steel placement rack 11.
[0022] The top of the rotating frame 2 is equipped with a control handle 7, which is tilted upwards. As an optional technical solution of this utility model, this makes it easier to provide a grip position for the user. At the same time, a protective cover is added to the top of the control handle 7 to improve the comfort during operation.
[0023] The steel placement rack 11 is recessed downwards near its rotation center, and a gap is left between the bottom surface of the steel placement rack 11 and the angle ruler 6. As an optional technical solution of this utility model, this facilitates the provision of movement space for the saw blade of the cutting saw body 4, which is convenient for the steel to be cut at an angle. At the same time, a safe distance is left between the bottom surface of the steel placement rack 11 and the angle ruler 6 to avoid motion interference between the two.
[0024] Multiple limiting blocks 8 are installed on both sides of the top surface of the steel placement rack 11. The four limiting blocks 8 on one side are threaded with fastening bolts 9. As an optional technical solution of this utility model, this makes it easy to clamp the steel inside the steel placement rack 11 by rotating the locking bolts 9, and avoids the steel from shaking during the cutting process.
[0025] Two supporting rollers 10 are installed at the end of the steel placement rack 11 away from the pointer 12. As an optional technical solution of this utility model, this facilitates the support of the suspended position of the steel placement rack 11 and allows the steel to be placed horizontally on the top surface of the steel placement rack 11.
[0026] The following steps are required when using this steel edge cutting device:
[0027] 1) When using, rotate the steel placement rack 11 to the specified angle according to the requirements of the steel cutting angle, referring to pointer 12 and angle ruler 6;
[0028] 2) Rotate the handwheel 14 to make the lead screw 13 rotate and lock the position of the steel placement rack 11;
[0029] 3) Place the steel on the top surface of the steel placement rack 11, and press down the rotating rack 2 by controlling the handle 7 to align the saw blade of the cutting saw body 4 with the cutting position;
[0030] 4) Tighten the steel by rotating the fastening bolt 9;
[0031] 5) The cutting saw body 4 is powered on and operates. By controlling the handle 7 to press down the rotating frame 2, the steel is cut.
[0032] In summary, when using the device, a support frame 1 is installed, with a steel placement rack 11 rotatably mounted on the center of its top surface. An angle ruler 6 is also installed on the center of the top surface of the support frame 1, and a pointer 12 is installed on one side of the steel placement rack 11. This allows the steel placement rack 11 to rotate, with the pointer 12 pointing to the angle ruler 6 for easy measurement of the rotation angle. Simultaneously, the control handle 7 pulls the rotating frame 2 to rotate, causing the cutting saw body 4 to cut the steel. The overall structure is simple and easy to operate, thus achieving the purpose of cutting the edges and corners of the steel at a certain angle. Furthermore, a lead screw 13 and a handwheel 14 are installed. The lead screw 13 is threadedly connected to the center of the support frame 1. Rotating the handwheel 14 causes one end of the lead screw 13 to push the steel placement rack 11 to its rotational position, locking the position of the steel placement rack 11. Two support rollers 10 are installed on one end of the steel placement rack 11, which facilitates support for the suspended position of the steel placement rack 11 and allows the steel to be placed horizontally on the top surface of the steel placement rack 11.
