Description

Technical Field

[0001] This utility model belongs to the field of angle steel tower processing technology, and specifically relates to a cutting device for angle steel tower processing. Background Technology

[0002] An angle steel tower is a type of plate tower with downcomers. Its bubbling zone is composed of parallel angle steel bars, which are arranged in a direction parallel to the liquid flow direction.

[0003] Patent application number 2022208327825 discloses a cutting device for processing angle steel towers, including a processing table. A device base is fixedly connected to the top of the processing table via a support frame, and a cutting blade is located at the bottom of the device base. A material passage groove is formed on the top of the processing table, and connecting grooves are formed on both sides of the inner surface of the material passage groove. Two symmetrically distributed first electric push rods are fixedly connected to the outer surfaces of the two connecting grooves. A fixing block is slidably connected to the inner cavity of the connecting groove, and a receiving groove is formed on the inner surface of the two fixing blocks that are close to each other. This cutting device for processing angle steel towers uses the first electric push rods to push the fixing blocks to clamp the steel. If it is a pipe, the second electric push rod pushes the arc-shaped clamping plate away from the receiving groove to clamp and position the pipe. Then, a hydraulic cylinder drives the cutting blade to rise and fall to cut the steel in the material passage groove, thereby improving the stability and quality of the cutting.

[0004] However, during use, it is necessary to manually observe or mark points on the workpiece in advance to cut the workpiece to a certain length. This can easily cause errors in the length of the cut workpiece, and the workload is large and the work efficiency is low. At the same time, it is impossible to automatically feed the workpiece. Utility Model Content

[0005] In view of this, the present invention provides a cutting device for processing angle steel towers. The start-up drive component drives the feeding plate to move back and forth in a cycle through the transmission device, which pushes the workpiece to be automatically fed. When the other end of the workpiece contacts the first positioning plate, the automatic positioning function is realized. The operation limit device connects and fixes the first positioning plate to the guide rod. The distance between the first positioning plate and the cutting device can be adjusted as needed to realize the function of adjusting the automatic positioning length of the workpiece, thereby improving the cutting effect and accuracy.

[0006] The technical solution is as follows: A cutting device for processing angle steel towers includes a processing table.

A driving component is detachably installed on the side support plate. The driving component is connected to the feeding plate through a transmission device. Activating the driving component drives the feeding plate to move cyclically back and forth through the transmission device.

[0007] During use, the above technical solution works as follows: the start-up drive component drives the feeding plate to move back and forth through the transmission device, which pushes the workpiece to be automatically fed. When the other end of the workpiece contacts the first positioning plate, the automatic positioning function is realized. The operation limit device connects and fixes the first positioning plate to the guide rod.

[0023] 3. The end of the workpiece contacts the positioning rod and pushes the piston plate to move along the detection cavity, so that the second detection contact contacts the first detection contact to achieve automatic positioning. At the same time, the drive component is paused to stop feeding, and the clamping device and the cutting device are started to work, so that feeding, positioning and cutting are completed automatically, improving the accuracy and efficiency of cutting.

[0024] 4. The workpiece pushes the second positioning plate to move along the first groove, and pushes the second detection contact to contact the first detection contact.
