Description

Accurate die angle adjusting device for punching machine Technical Field The utility model relates to the technical field of punching machines, in particular to a die angle accurate adjusting device for a punching machine. Background The punch press is a machine tool widely applied in the field of sheet metal machining, and mainly depends on various dies with different shapes and sizes to machine the sheet metal, and holes with the same shape are often required to be machined on the same sheet metal, and are distributed at different positions and angles on the sheet metal. To finish the processing of the holes, the placement angle of the die must be changed and adjusted one by one according to the requirements of the processing drawing. Traditional old punch press, to this kind of mould angle's adjustment need spend a large amount of time, leads to can not make the processing of complicated part almost at an equipment, can only be according to the drawing requirement, become different processes with Kong Cafen of different angles, every process needs a lathe and a set of mould, and several lathes cooperate each other, just can accomplish panel processing according to the drawing requirement. The processing flow, the required numerous machine tools and dies, inevitably brings high processing cost and wastes time caused by circulation among various working procedures; Therefore, a mechanism capable of enabling the die to automatically rotate at an angle is needed to be designed, and the mechanism can automatically rotate at an angle according to the drawing requirements under the driving of a servo motor to finish the processing of the same hole at different angles. Disclosure of Invention The utility model aims to solve the problems in the prior art and provides a die angle accurate adjusting device for a punch press. The utility model has the specific scheme that the die angle accurate adjusting device for the punch press comprises a base, a shell is fixedly arranged on the base, a die mounting seat is arranged in the center of the shell and is used for mounting a die, the lower end of the die mounting seat is in sliding connection with the base, the upper end of the die mounting seat is in sliding connection with the shell, a circle of worm wheel is fixedly arranged on the side wall of the die mounting seat, a containing cavity is arranged in the shell corresponding to the worm wheel, a worm is arranged in the containing cavity and is matched with the worm wheel, two ends of the worm extend outwards and are in rotating connection with the shell, and one end of the worm is connected to a driving mechanism. Further, a bearing seat is respectively arranged at two ends of the worm, bearings are respectively arranged between the worm and the two bearing seats, the bearing seats are connected with the shell through bolts, bolt holes are formed in the bearing seats, adjusting gaps are formed between the bolt holes and the bolts, jackscrews are respectively arranged on the shell corresponding to the two bearing seats, and the jackscrews are used for adjusting the positions of the bearing seats so as to adjust the gaps between the worm and the worm wheel. Further, sealing rings are arranged between the bearing seat and the shell as well as between the worm and the worm, sealing rings are arranged between the base and the die mounting seat and between the shell and the die mounting seat, sealing areas are formed by encircling the sealing rings, the worm wheel and the worm are located in the sealing areas, and lubricating oil is filled in the sealing areas.
