The invention has the advantages of simple structure, low cost, long service life and easiness for regulation.

Description

Technical field [0001] The invention relates to a component of a bending machine, in particular to a back gauge linear rail moving clamp device of the bending machine. Background technique [0002] The rear stopper mechanism of the bending machine is an important working mechanism of the bending machine. The rear stopper installed on it is a necessary part for positioning the sheet and ensuring the contour accuracy of the workpiece. The rear stopper is different according to the shape and size of the workpiece. Need to adjust the horizontal position and height position. After the plate is in position, it is close to the back stopper. When the bending is in progress, the two sides of the plate will turn up, and the angle between the two sides of the plate will become smaller. Due to the thickness of the plate, the plate will be initially turned up. The material will force the back stopper to leave, especially when bending thick sheets, this phenomenon is more obvious, which will ...

Problems solved by technology

However, in non-NC machines, the back gauge block cannot be retracted automatically, and the back gauge mechanism is often damaged. If manual material release is used, the labor intensity of workers will be increased and work efficiency will be reduced.

[0003] In the prior art, the backgauge device of the bending machine includes a pair of R-axis rails parallel to each other, a pair of mutual Parallel X-axis rails, Z-axis rails arranged on the pair of R-axis rails and perpendicular to the R-axis rails and the X-axis rails, the slidable device on the Z-axis rails There is a pair of retaining fingers, and the retaining fingers are moved in the track through the rail moving clip device provided at the bottom, and the track is a circular guide rail, a hexagonal guide rail or a prismatic guide rail, but in the prior art When the wire rail moving clip device moves in the track, the wire rail moving clip device is prone to slack, and if the wire rail moving clip device is loose, the retaining finger will not move smoothly on the rail, And the resistance of the finger moving in the track increases, so the precision of CNC bending machine processing is not high; therefore, the staff needs to take out the finger from the track and adjust it after the moving clip device of the line rail is loose. , which increases the workload and work intensity of the staff, and the moving clamp device of the line rail can not be adjusted to the best state when the staff adjusts it after many times of loosening, so the line rail moves The clip device does not have a long service life and needs to be replaced periodically, increasing production costs
