Description

Technical Field

[0001] This utility model belongs to the field of angle steel processing technology, and specifically relates to a material cutting mechanism for processing steel materials for power transmission angle steel towers. Background Technology

[0002] Transmission angle steel tower: The main components are angle steel, and other components are lattice towers composed of angle steel or shaped steel. Angle steel is the main accessory of angle steel tower. It needs to be cut and ground to make the steel pipe meet the size requirements of steel pipe tower. In the current angle steel processing, the material is generally cut manually, which is labor-intensive and inefficient.

[0003] Application No. 2022220687416 discloses a steel processing and unloading mechanism for power transmission angle steel towers, relating to the field of power transmission angle steel tower steel processing technology. It includes a processing table with clamping components for fixing angle steel on both the front and rear sides of the top of the processing table. An ejection mechanism is located on the top of the processing table, between the two clamping components. After the angle steel on the processing table is processed, the clamping components are loosened. Then, due to the ejection mechanism, a multi-stage hydraulic cylinder drives a rack to rise via a connecting bar, thereby driving a gear to rotate. The gear rotates from... The first pulley rotates, which in turn drives the second pulley to rotate. The rotation of the second pulley drives the rotating rod and the ejector plate to rotate. The rack rises, causing the ejector block to rise and lift the angle steel. The rotation of the ejector plate causes the lifted angle steel to detach from the ejector block and slide down to the lower slide plate, completing the automatic unloading. No manual handling is required, which reduces labor intensity and improves work efficiency. However, after the angle steel slides down the lower slide plate, it needs to be picked up and stacked manually. During the sliding process, the angle steel is prone to collision with each other, resulting in the accumulation or damage of the angle steel, which affects the production quality of the angle steel.

By controlling the rotation time of the first driving component 5, the distance the first support frame 6 moves is determined. The third driving component 20 is then activated, driving the transmission gear 21 to rotate. The transmission gear 21 then... The moving rack 23 moves up and down, driving the third sliding frame 22 to move along the second sliding groove 19 on the second support frame 18, thereby adjusting the height of the electro-permanent magnet suction device 27. The second drive component 14 is activated to drive the double threaded rod 12 to rotate through the second rotating shaft 13. The double threaded rod 12 drives the two first sliding blocks 16 to move synchronously relative to each other or in opposite directions along the first sliding groove 7, thereby adjusting the position of the two electro-permanent magnet suction devices 27, enabling the lifting of angle steel of different lengths, and preventing the angle steel from shifting and falling during lifting.
