Description

Technical Field

[0002] Angle steel, also known as angle iron, is a type of steel with two sides perpendicular to each other. It can be divided into equal-leg angle steel and unequal-leg angle steel according to its shape, both of which are widely used in various building structures and engineering fields. The main characteristics of angle steel are its excellent mechanical properties and ease of processing and welding. In steel structure production, there are many components assembled from angle steel. In this case, we need to shear the angle steel. Shearing equipment generally does not have a fixed-length function. Usually, marking is used to control the shearing size of the angle steel. The marking process is manual and labor-intensive, and there is a certain amount of arc error, which may cause parts in the same batch to be uneven. A fixed-length tool is urgently needed to solve this problem.

[0003] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0023] like Figures 1 to 4 As shown, the fixed-length device for angle steel shearing includes a supporting angle steel 1 and an auxiliary supporting seat 13. The upper part of the supporting angle steel 1 is located on the inner side of the right angle and is fixedly provided with a fixing nut 5. A lead screw 7 is installed in the fixing nut 5 through threaded cooperation. One end of the lead screw 7 is a straight structure and the other end is a bent structure. The straight structure end of the lead screw 7 is connected to one end of the extension sleeve 9 by a thread. The other end of the extension sleeve 9 is provided with a shear positioning plate 12. The extension sleeve 9 is provided with an auxiliary supporting seat 13 at a lower position near one end of the shear positioning plate 12. The lower part of the auxiliary supporting seat 13 is fixedly connected to the lifting adjustment rod 14. The lower end of the lifting adjustment rod 14 is slidably connected to the main support rod 15. The lower end of the main support rod 15 is fixedly provided with a supporting base plate 17, and the lower end of the supporting angle steel 1 is fixedly provided with a fixed base plate 2.

[0024] Among them, a connecting end 10 is integrally provided at the end position of one end of the extended sleeve 9 and the screw 7. The diameter of the connecting end 10 is larger than the outer diameter of the extended sleeve 9. A limiting plate 11 is provided at the outer end surface of the connecting end 10. A through hole is opened on the limiting plate 11, and the screw 7 passes through the through hole of the limiting plate 11.

[0025] A locking nut 18 is installed on the lead screw 7 on the side of the limiting plate 11 away from the connecting end 10, and anti-slip grooves are provided on both sides of the limiting plate 11 to provide a self-locking effect of the thread fit.

[0026] A stud is welded on one side of the shear positioning plate 12 that cooperates with the extension sleeve 9. The shear positioning plate 12 and the extension sleeve 9 are connected by threads, which makes them easy to disassemble and replace.

[0027] The supporting angle steel 1 is fixed to the fixed base plate 2 by welding. A reinforcing rib 4 is provided between the right-angled inner side of the supporting angle steel 1 and the fixed base plate 2 to improve the structural stability. Fixed mounting holes 3 are processed at the four corners of the fixed base plate 2 to facilitate fixing the device on the ground.

[0028] One end of the fixing nut 5 is fixed to the supporting angle steel 1 by welding, and a fixed connecting block 6 is provided in the middle position of the side of the fixing nut 5. The fixed connecting block 6 and the supporting angle steel 1 are fixed by welding. The fixing nut 5 is in a horizontal state, and a handle 8 is provided at the end position of one end of the bending structure of the screw 7. The outer side of the main support rod 15 is provided with an adjusting top screw 16 through a threaded connection.

[0029] The working principle of the utility model is as follows: the fixed base plate 2 is fixedly installed on the side of the angle steel shearing device, in the direction of the telescopic movement of the angle steel, and the handle 8 is adjusted to adjust the horizontal movement of the lead screw 7 relative to the fixed nut 5, thereby adjusting the position of the shear positioning plate 12. The end face of the shear positioning plate 12 is used to fix the length and position one end of the angle steel. By detecting the distance between the end face of the shear positioning plate 12 and the shearing tool, the shearing size specification of the angle steel can be controlled. After adjusting to the appropriate size specification, batch shearing processing can be carried out, thereby ensuring the shearing quality of the angle steel.

[0030] The extension sleeve 9 is provided with different length specifications, which facilitates the wide adjustment of the shear positioning plate 12, so as to meet the shearing and fixed length processing requirements of angle steels of different length specifications;

[0031] The auxiliary support seat 13 is designed as a curved surface structure. A lifting adjustment rod 14 is provided below the auxiliary support seat 13. The relative height between the lifting adjustment rod 14 and the main support rod 15 can be adjusted. The adjustment position is locked by adjusting the top screw 16. The lifting adjustment rod 14 and the main support rod 15 are both square tube structures and will not rotate relative to each other, ensuring that the auxiliary support seat 13 provides auxiliary support for the extended sleeve 9. This device can be used not only for cutting angle steel, but also for fixed lengths such as channel steel and wire rods.

[0032] The utility model provides a fixed length device at one end of the angle steel shearing equipment, which can position one end of the sheared section of the angle steel, and thus control the length of the sheared section of the angle steel. The fixed length device is equipped with an auxiliary support seat 13, which effectively supports the end of the extension sleeve 9 close to the shear positioning plate 12, ensuring the stability of the fixed length device structure. The fixed length device can achieve a small range of adjustment of the fixed length distance by rotating the screw 7, and can also achieve a large range of adjustment by replacing the extension sleeve 9. The angle steel shearing process does not require repeated marking, which greatly improves production efficiency, ensures that parts in the same batch have the same size, effectively reduces labor intensity, and is simple to manufacture and has a very low production cost.

[0033] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above-mentioned technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
