Description

Technical Field

[0001] This utility model belongs to the field of steel structure processing technology, specifically, it relates to a length-fixing device for cutting steel structures. Background Technology

[0002] Structural components are building structural components made of steel materials. They are one of the main types of building structures and are mainly made of steel beams, steel columns, steel trusses, etc., made of steel sections and steel plates. In the field of steel structure processing, precise cutting of steel structures is a key link to ensure project quality.

[0003] Steel structure workpieces are generally manufactured to a fixed length. However, during the construction of steel structure buildings, the workpieces need to be cut according to the construction drawings using a cutting device to obtain the required length. To ensure precise control of the dimensions of the steel structure workpieces, a length-fixing device is required to perform a length-fixing operation before cutting. Existing cutting equipment with length-fixing function typically uses a method of placing the top of the steel structure component against a baffle and using graduated lines for length-fixing. However, in actual cutting, the saw blade generates a large force, which easily causes the steel structure workpiece to deviate. Once the workpiece deviates, the accuracy of the cutting length is greatly reduced, resulting in the dimensions of the cut steel structure component not meeting the design requirements. Therefore, this utility model is proposed. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0020] Example 1:

[0021] Reference Figures 1-3 A steel structure cutting device for fixed-length cutting includes a cutting table 1, and further includes: a movable base 3 movably mounted on the cutting table 1; a first drive mechanism for driving the movable base 3 to move, mounted on the cutting table 1; a first mounting frame 301 fixedly connected to the movable base 3; a clamping plate 304 disposed between the first mounting frame 301 and the movable base 3; an adjusting screw 303 threadedly connected to the first mounting frame 301, and its lower end rotatably connected to the clamping plate 304; and a support roller 4 rotatably connected to the cutting table 1 away from the movable base 3. One end of the movable seat 3; a second mounting frame 401, fixedly connected to the cutting table 1 near the support roller 4; a mounting base 405, symmetrically arranged on the second mounting frame 401; a positioning wheel 406 rotatably connected to the mounting base 405; a second drive mechanism for driving the two mounting bases 405 to move synchronously, mounted on the second mounting frame 401; a limiting plate 302, fixedly connected to the side of the first mounting frame 301 away from the second mounting frame 401; and a scale line 102 used in conjunction with the movable seat 3, set on the cutting table 1.

[0022] The first drive mechanism includes a threaded rod 2 and a first motor 201. A through slot 101 is provided on the cutting table 1. The threaded rod 2 is rotatably connected in the through slot 101. The movable seat 3 is threadedly connected to the threaded rod 2. The first motor 201 is fixedly connected to one end of the cutting table 1 away from the second mounting frame 401. The output end of the first motor 201 is fixedly connected to the end of the threaded rod 2.

[0023] The second drive mechanism includes a bidirectional lead screw 402, a second motor 403, and a fixed rod 404. The bidirectional lead screw 402 is rotatably connected to the second mounting frame 401, the fixed rod 404 is fixedly connected to the second mounting frame 401, the mounting base 405 is slidably connected to the fixed rod 404 and threadedly connected to the bidirectional lead screw 402, and the second motor 403 is fixedly connected to one side of the second mounting frame 401, and its output end is fixedly connected to the end of the bidirectional lead screw 402.

[0024] When cutting steel structure workpieces to a fixed length, the operator first places the steel structure on the movable seat 3 and the support roller 4, and makes one end of the steel structure workpiece abut against the limiting plate 302. The first motor 201 is started by the first drive mechanism, and the first motor 201 drives the threaded rod 2 to rotate. Since the movable seat 3 is threadedly connected to the threaded rod 2, the movable seat 3 will move along the axial direction of the threaded rod 2 on the cutting table 1. During the movement of the movable seat 3, the operator can determine the position of the movable seat 3 according to the scale line 102 on the cutting table 1, thereby realizing the fixed length operation of the steel structure.

[0025] After the end of the steel structure workpiece is placed on the movable seat 3, the adjusting screw 303 can be rotated. The lower end of the adjusting screw 303 is rotatably connected to the clamping plate 304. As the adjusting screw 303 rotates, the clamping plate 304 moves up and down between the first mounting frame 301 and the movable seat 3, thereby clamping the steel structure workpiece placed on the movable seat 3. At the same time, the second motor 403 of the second drive mechanism is started. The second motor 403 drives the bidirectional lead screw 402 to rotate. The mounting seat 405 is threadedly connected to the bidirectional lead screw 402 and slidably connected to the fixed rod 404. Therefore, the two mounting seats 405 will move closer or further away synchronously under the drive of the bidirectional lead screw 402. When the two mounting seats 405 move closer, the positioning wheel 406 on the mounting seat 405 will contact the steel structure workpiece and apply pressure. Together with the support roller 4, the steel structure workpiece is stably supported and positioned from multiple directions.

[0026] After completing the above-mentioned length setting and clamping positioning operations, the cutting equipment can then be used to cut the steel structure workpiece. Since the steel structure workpiece is firmly clamped and positioned, it will not shift due to the saw blade cutting during the cutting process.

[0027] While existing steel structure cutting machines can control the cutting length by placing the top of the steel structure component against a baffle for fixed-length operation, the workpiece is prone to shifting due to the saw blade during cutting, leading to reduced cutting length accuracy. This device, through the cooperation of components such as clamping plate 304, support roller 4, and positioning wheel 406, can stably clamp and position the steel structure workpiece during and after the fixed-length operation, effectively avoiding the problem of steel structure shifting due to cutting. This significantly improves the accuracy of the cut workpiece and ensures the accuracy and consistency of the cutting length, which is of great significance for improving the processing quality and production efficiency of steel structures.

[0028] Example 2:

[0029] Reference Figures 1-3 A steel structure cutting device for measuring length, basically the same as in Embodiment 1, but with a further improvement: the clamping plate 304 is arc-shaped, and an elastic rubber pad 305 is fixedly connected to the inner wall of the clamping plate 304, such as... Figure 1 , Figure 2 As shown, by making the clamping plate 304 arc-shaped and setting the elastic rubber pad 305 on the clamping plate 304, it can be applied to steel structure workpieces of different shapes when clamping and positioning the end of the steel structure workpiece, thereby improving the applicability of the device. At the same time, under the action of the elastic rubber pad 305, the contact area between the clamping plate 304 and the workpiece can be increased, ensuring the clamping effect on the workpiece.

[0030] Guide rods 306 are symmetrically fixedly connected to both sides of the adjusting screw 303 on the clamping plate 304. The guide rods 306 are slidably connected to the first mounting frame 301. When the adjusting screw 303 is rotated to adjust the clamping plate 304 up and down, the guide rods 306 can provide precise guidance for the clamping plate 304, ensuring that the clamping plate 304 moves smoothly in the vertical direction. This avoids the clamping plate 304 tilting or shaking due to uneven force on the adjusting screw 303 or thread clearance, thereby ensuring that the clamping plate 304 can accurately clamp and position the steel structure, improving the reliability of clamping. Furthermore, when moving the clamping plate 304, there is no need to manually support the clamping plate 304.

[0031] Multiple grooves are equally spaced on both lower ends of the movable seat 3. Ball bearings 307 are movably connected in the grooves. The ball bearings 307 roll on the cutting table 1. The rolling of the ball bearings 307 on the surface of the cutting table 1 transforms the sliding friction between the movable seat 3 and the cutting table 1 into rolling friction. Compared with sliding friction, the resistance of rolling friction is significantly reduced, making the movable seat 3 move more easily and smoothly on the cutting table 1. At the same time, it reduces the frictional loss between the movable seat 3 and the cutting table 1, reduces the wear of the parts, and avoids the problem of the movable seat 3 tilting after gaps are generated due to wear.

[0032] A rangefinder 103 is fixedly connected to one end of the cutting table 1 near the limit plate 302. The detection end of the rangefinder 103 faces the limit plate 302. Adding a rangefinder 103 to one end of the cutting table 1 near the limit plate 302 can bring higher precision and intelligence to the fixed-length operation. The staff can choose to use the rangefinder 103 or the scale line 102 according to the actual needs.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
