Embodiment Construction

[0016] Such as Figures 1 to 4 shown

[0017] The device includes a base 1, two support rods 2, a beam 3 and a pressing assembly.

[0018] The base 1 is generally a rectangular frame structure. Two channel steels 11 are vertically welded on the upper end of the base 1 so that the openings of the two channel steels 11 are correspondingly outward. The side walls of the two channel steels 11 and the upper end of the base 1 are jointly formed Pressure groove 5, two limit baffles 12 are welded on the base 1; two vertical support rods 2 are welded on the base 1, and the two support rods 2 are distributed on both sides of the length direction of the pressing block, and the horizontal beam 3 The two ends are welded on the upper ends of the two support rods 2 .

[0019] The pressing assembly includes a jack 41, a fixed block 42, a pressure bar 43 and a mandrel 44 matched with the pressure groove 5. The mandrel 44 is cylindrical, the upper end of the fixed block 42 matches the lower e...

Abstract

The invention provides a personal protective equipment hinging shaft protecting shell forming device which comprises a base, two supporting rods, a cross beam and a press-fit component. A pressing groove is formed in the upper end face of the base, the cross beam is fixed on the upper side of the base through the supporting rods, the press-fit component is arranged between the base and the cross beam and at least comprises a jack and a core rod matched with the pressing groove, and the jack is positioned between the cross beam and the core rod. A steel plate is placed on the upper side of the pressing groove, the jack is operated, a piston rod of the jack extends, the upper end of the jack is abutted against the cross beam, and the jack drives the core rod on the lower side to move downwards to extrude the steel plate into the pressing groove; under action of the core rod, the middle portion of the steel plate is gradually extruded into the pressing groove and bent to be coincident with an arc of the outer wall of the core rod, and the steel plate forms an arc-shaped hinging shaft protecting shell to complete hinging shaft protecting shell forming.

Description

technical field [0001] The invention relates to a forming device for a hinge shaft shield of civil air defense equipment. Background technique [0002] The hinge shaft shield in civil air defense equipment products is made of bending thin steel plates into arc shapes. Due to the large size of the workpiece, it is difficult to process it on ordinary equipment, and there is no processing equipment for this type of workpiece. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hinge shell forming device for civil air defense equipment with simple structure and convenient processing. [0004] In order to solve the above-mentioned technical problems, the present invention provides a hinge shell forming device for civil air defense equipment, which includes a base, two support rods, a beam and a press-fit assembly. There is a pressure groove on the upper end of the base, and the beam is fixed by two support rods. on the...
