Description

Technical Field

[0001] This application relates to the field of sheet metal processing equipment technology, and in particular to a sheet metal bending machine with precise positioning function. Background Technology

[0002] Bending machines are important equipment in the sheet metal industry for bending and forming workpieces. Their function is to press steel plates into parts of various shapes according to process requirements. They can press metal sheet materials together from top to bottom and extrude them. They are commonly used in the metal processing industry.

[0003] A search revealed that patent document CN215236984U discloses a bending machine with precise positioning function, including a base, a frame, and a connecting plate. A processing table is fixed to the top of the base. A clamping structure is provided on one side of the top of the processing table, including a bracket, a clamping head, a mounting groove, a rotating rod, and a rotating wheel. A positioning structure is provided on the other side of the top of the processing table. A frame is fixed to the top of the processing table, and a hydraulic rod is installed on one side of the bottom of the frame. A connecting plate is installed at the bottom of the hydraulic rod, and a bending head is provided at the bottom of the mounting structure. By providing the clamping structure, the operator can place one side of the sheet metal under the clamping head at the bottom of the mounting groove. After adjusting the position of the sheet metal, the rotating wheel on the rotating rod can be manually rotated. Through the threaded engagement, the mounting groove moves downward, and the clamping head fixes the sheet metal, preventing it from moving during processing.

[0040] In this application, during operation, the sheet metal workpiece is first placed on the bottom inner wall of the clamping seat 6 and the support seat 101. Rotating the clamping screw 601 clockwise causes the pressure block 602 to spiral downwards, achieving initial clamping and fixing of one end of the sheet metal workpiece. Shaking the rotating wheel 203 by holding the handle causes the lead screw 201 to rotate, which in turn causes the lead screw seat 202 to rotate, allowing the clamping seat 6 to move the sheet metal workpiece left and right, thus adjusting its position and enabling precise bending. After adjusting the bending position, the hydraulic cylinder 501 is activated. The output shaft of the hydraulic cylinder 501 causes the lifting plate 502 to move downwards, which in turn causes the push plate 401 to move downwards. The push plate 401 then pushes the reset plate 301 downwards through the plate hole 402, thus moving the spring... When the spring 304 is compressed, it can drive the rack plate 302 to move downward, drive the gear 303 to rotate clockwise, drive the bidirectional screw 7 to rotate clockwise, drive the two screw seats 701 to move closer to each other, and drive the two clamping blocks 702 to move closer to each other. This allows the sheet metal workpiece to be clamped and fixed again by the two clamping pads 703. The clamping pads 703 have buffering and anti-slip properties, which can improve the clamping stability of the sheet metal workpiece and thus prevent the sheet metal workpiece from shifting during the bending process, thus affecting the bending quality. At the same time, the lifting plate 502 drives the bending head 503 to move downward continuously, which can achieve the purpose of bending the sheet metal workpiece by the bending head 503.
