Ship square steel step die-pressing device

Abstract

The invention discloses a ship square steel step die-pressing device. The ship square steel step die-pressing device comprises a lower die and an upper die. The lower die is fixed to a lower die base of an oil press, and the upper die is fixed under an upper die base of the oil press. The middle of the lower die is provided with a rectangular through hole, the positions, on four side faces of the rectangular through hole, of the lower die are provided with a plurality of first vertical V-shaped slots, the first vertical V-shaped slots in every two opposite faces are the same in number and are in one-to-one correspondence in position, and the upper surface of the lower die is further provided with a plurality of first horizontal V-shaped slots communicating with the first vertical V-shaped slots in the longitudinal and transverse directions. The upper die comprises a male die matched with the rectangular through hole, the periphery of the male die is provided with second vertical V-shaped slots in one-to-one correspondence to the first vertical V-shaped slots, and the bottom face of the male die is further provided with a plurality of second horizontal V-shaped slots, wherein the second horizontal V-shaped slots are criss-cross, and the two ends of the second horizontal V-shaped slots communicate with the second vertical V-shaped slots in the two opposite sides of the male die.

Description

technical field [0001] The invention relates to a forming device, in particular to a square steel step pressing die device for ships. Background technique [0002] In order to make it easier for people to go up and down and work in the ship cabin, a large number of square steel steps need to be installed around each ladder. The traditional square steel step processing method is that the processing personnel take the square steel to be processed and place them one by one. Processing on the platform not only consumes a lot of labor, but also is very inefficient. Square steel steps often have poor quality and poor precision, and require fire adjustment. After installation on the ship, it is easy to cause rework and increase work. quantity, prolonging the ship construction cycle. [0003] After searching, it was found that the patent No. 201520186352.0 discloses a step bending die tooling for ship outfitting, which includes an upper die and a lower die respectively installed on...

[0002] In order to make it easier for people to go up and down and work conveniently in the ship cabin, basically a large number of square steel steps need to be installed around each boarding ladder. The traditional square steel step processing method is Processors take the square steel that needs to be processed and put them on the platform one by one, which not only consumes a lot of labor, but also has very low efficiency. There are often cases of poor quality and poor precision of the finished products of square steel stepping, and it is necessary to Fire adjustment treatment, it is easy to cause rework after installation on the ship, thus increasing the workload and prolonging the ship construction cycle

[0003] After searching, it was found that the patent No. 201520186352.0 discloses a step bending die tooling for ship outfitting, which includes the pressure head and workbench respectively installed on the hydraulic press Upper die and lower die, the upper die is provided with a blade for pressing down the bent square steel, the lower die is symmetrically provided with two platforms, the square steel is placed one by one in the lower edge of the platform along the width direction of the platform, the upper die Driven by the pressure head of the hydraulic press, it moves down, so that the blade presses down on the square steel on the platform and cooperates with the two round steel between the two platforms to bend the square steel into a right angle. Adjust the direction of the square steel to place the remaining right angle as above The steps are bent one by one to complete the bending of the square steel steps. Compared with the traditional manual hot bending, although this tool can also bend multiple square steel angles at the same time, it also eliminates the heating process of the square steel, but it still needs two operations during processing. The suppression of square steel steps can only be completed once, and the bending angles at both ends are also difficult to control and unify
