Abstract

The invention discloses a numerical control groove punching machine and a groove punching method of the numerical control groove punching machine. The numerical control groove punching machine comprises a machine frame, a controller, a groove punching mechanism and a numerical control feeding mechanism, wherein the controller, the groove punching mechanism and the numerical control feeding mechanism are arranged on the machine frame. The numerical control groove punching mechanism comprises a base plate, a double-acting air cylinder and a punching block, wherein the double-acting air cylinder is arranged on the base plate, and the punching block is used for driving an upper die of the groove punching machine to work. A piston rod of the air cylinder is connected with the punching block through a boosting and frequency-increasing mechanism. The boosting and frequency-increasing mechanism comprises an upper boosting arm and a lower boosting arm. The upper end of the upper boosting arm is hinged to the base plate through a hinge base. The lower end of the upper boosting arm, the upper end of the lower boosting arm and the tail end of the piston rod are hinged through the same hinge shaft. The lower end of the lower boosting arm is hinged to the punching block. The numerical control groove punching machine and the groove punching method of the numerical control groove punching machine solve the problems that in the prior art, a grooving machine is high in production cost, low in grooving speed, and the groove depth consistency is poor. The numerical control groove punching machine is low in production cost, high in grooving speed, capable of accurately controlling the groove depth and conducting double-faced grooving, and high in practical value.

Description

technical field [0001] The invention relates to the technical field of stamping processing, in particular to a numerically controlled grooving machine with high precision, high speed and low cost and a grooving method thereof. Background technique [0002] In the field of advertising signboard production, it is necessary to slot horizontally on the strip-shaped metal sheet and bend it at the slot to form the frame of the hollow text. Since the thickness of the metal plate that constitutes the frame of the hollow text is usually small, so in The accuracy of the depth of the groove on the board is very high. The slotting methods of the traditional slotting machine are roughly divided into three types. The first method is to use a milling cutter to mill the slot. Its disadvantages are that the milling cutter is expensive and has a short service life, which is especially obvious when processing stainless steel. The second way is to use a planer for grooving. The disadvantage is...
