[0016] The present invention provides a bending machine for processing industrial and mining accessories. It has the following beneficial effects: (1) In the bending machine for processing industrial and mining parts, the worker places the bending part inside the clamping tube and starts the hydraulic cylinder 1. The clamping tube clamps the bending part, and then the slide moves toward the direction close to the pressure plate until it passes through the inside of the pressure plate. The movement of the clamping table 1 drives the tooth plate to move through the connecting block. The tooth plate moves to contact and squeeze the surface of the tooth plate, and drives the tooth plate downward under the action of the tooth plate surface, so that the tooth plate can pass through, thereby preventing the tooth plate from rotating when the clamping table 1 moves for clamping, thereby driving the clamping tube to rotate, resulting in the bending part not being properly fixed or The rotating parts lose control and move unnecessarily, causing the angle of the bending part to shift, which in turn affects the processing accuracy or causes the processing results to be unqualified. The toothed plate moves and contacts and drives the toothed disc to rotate counterclockwise. The counterclockwise rotation of the toothed disc drives the clamping tube to rotate. At this time, the rotation of the clamping tube drives the bending part to rotate 180 degrees, thereby realizing the control of the rotation limit of the clamping tube, avoiding that when the clamping table is clamping the bending part, the clamping tube rotates, causing the bending part to rotate excessively or shift, thereby causing the bending angle of the bending part to be inaccurate or material damage.

[0017] (2) The bending machine for processing industrial and mining accessories moves the inclined block 2 in a direction away from the inclined block 1 under the action of the inclined block 1. At the same time, the movement of the inclined block 2 drives the sliding rod to move the extrusion clamping box in a direction close to the clamping table 1 until the bending part is clamped, thereby achieving a stable effect on the bending part during processing, ensuring that the position of the bending part does not shift during the bending process, thereby improving the bending accuracy and consistency. In addition, the stable fixation of the bending part helps to reduce abnormal stress or impact generated by the bending part during the bending process. The rotation of the rotating shaft drives the eccentric wheel to rotate. At this time, the rotation of the eccentric wheel will contact and squeeze the pressure plate to move downward. At the same time, the downward movement of the pressure plate will drive the knocking plate to move downward. The knocking plate moves downward to knock on the bending part, further improving the fit between the clamping box and the clamping table 1 and the bending part, thereby improving the stability of the bending part during processing, avoiding the bending part being disturbed by external forces, resulting in deformation, warping or twisting during the bending process, thereby affecting the yield rate of the processed bending part.

[0018] (3) The bending machine for processing industrial and mining accessories, by moving the extrusion plate in the direction away from the L-shaped plate under the action of the L-shaped plate, pumps the lubricating oil in the lubrication box to the oil inlet pipe. At this time, the movement of the extrusion plate drives the convex block to move, and the convex block moves until it blocks the partition, thereby realizing the control of the lubricating oil output capacity. The effect of quantitative oil output is achieved by limiting the oil inlet of the partition. At the same time, it also avoids the occurrence of large friction between the pressure plate and the bending part when the bending part is bent and clamped. The lubricating oil accumulated in the quantitative box is discharged through the oil outlet pipe, thereby ensuring that the amount of lubricating oil used each time is the internal volume of the quantitative box, ensuring that the operation of the pressure plate is more stable, thereby improving the bending accuracy of the bending part. Lubrication can effectively avoid uneven sliding or excessive resistance between the pressure plate and the bending part, and further improve the control of the lubricating oil output capacity.

At the same time, the downward movement of the pressure plate 611 will drive the knocking plate 612 to move downward. The knocking plate 612 moves downward to knock the bending portion 81, further improving the fit between the clamping box 61 and the clamping platform 43 and the bending portion 81, thereby improving the stability of the bending portion 81 during the processing, avoiding the bending portion 81 being disturbed by external force, resulting in deformation, warping or twisting during the bending process, thereby affecting the yield of the processing bending portion 81.

[0034] When the clamping box 61 moves in the direction close to the bending portion 81 under the action of the clamping platform 1 43, it drives the L-shaped inclined plate 712 to move. At the same time, the clamping platform 2 45 moves in the direction close to the bending portion 81, driving the L-shaped plate 72 to move. The L-shaped plate 72 moves until it contacts and squeezes the squeezing plate 73. At the same time, the squeezing plate 73 moves in the direction away from the L-shaped plate 72 under the action of the L-shaped plate 72 to pump the lubricating oil inside the lubrication box 71 to the oil inlet pipe 77. At this time, the squeezing plate 73 moves and drives the protrusion 75 to move. The protrusion 75 moves until it blocks the partition 76, thereby realizing the control of the lubricating oil output capacity. The effect of quantitative oil output of the lubricating oil is achieved by limiting the oil inlet of the partition 76. At the same time, it also avoids the occurrence of large friction between the pressure plate 24 and the bending portion 81 when the bending portion 81 is bent and clamped. If there is no effective lubrication , the friction force will increase, which will lead to wear on the surface of the pressure plate 24 and the bending portion 81, reducing the service life of the equipment. At the same time, the L-shaped inclined plate 712 moves to contact and squeeze the limit plate 79 to move upward, and the limit plate 79 drives the oil outlet pipe 710 to move until it coincides with the oil outlet hole on the surface of the metering box 78. At this time, the lubricating oil accumulated inside the metering box 78 will be discharged through the oil outlet pipe 710, thereby ensuring that the amount of lubricating oil used each time is the internal volume of the metering box 78, ensuring that the operation of the pressure plate 24 is more stable, thereby improving the bending accuracy of the bending portion 81, and lubrication can effectively avoid uneven sliding or excessive resistance between the pressure plate 24 and the bending portion 81, further improving the control of the lubricating oil output capacity, avoiding excessive lubricating oil causing leakage or pollution to the processing area, or insufficient lubricating oil causing overheating and damage to the equipment.
