Punching mechanical die for marine flat-bulb steel

Abstract

The invention relates to a punching mechanical die for marine flat-bulb steel. The punching mechanical die comprises a hydraulic pressure head, a bracket and a punching die cutter; the bracket comprises an upper shaft fixing plate, a lower shaft fixing plate and a guide plate; the upper shaft fixing plate, the lower shaft fixing plate and a guide plate are arranged from top to bottom; an open holeis formed in the upper shaft fixing plate; the guide plate can move up and down between the upper shaft fixing plate and the lower shaft fixing plate; a discharging hole is formed in the lower shaftfixing plate; the die punching cutter is fixed to the lower end of the guide plate; and the hydraulic pressure head is connected with the guide plate. By means of the punching mechanical die, the problems of low efficiency and poor quality of flat-bulb steel machining on a shipbuilding site are effectively solved; machined water leakage holes are uniform in shape; the probability of secondary machining is reduced; and time, manpower and material resources are greatly saved.

Description

technical field [0001] The invention relates to the field of ship component processing machinery, in particular to a punching machine die for a ship's flat spherical steel. Background technique [0002] In shipbuilding, some of the flat bulbs inside the hull need to process water leakage holes. Usually, there are 8-10 leakage holes in a piece of flat bulb steel. The traditional processing technology is to use oxyacetylene cutting. Due to the technical level of the operators, Due to the difference in physical strength, the stability of the cutting cannot be guaranteed during operation, and it is easy to cause problems such as dross hanging, the size of the cutting hole cannot be guaranteed, and the cutting place is not smooth enough. Follow-up grinding and repair operations are often required, resulting in low efficiency, high cost, and low quality. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a ...
