Problems solved by technology

[0002] Existing air defense doors are usually four angle steels welded into a frame shape, and the upper side of the angle steel is welded with a pressure plate and an oblique flat steel. The welding method is to first position the pressure plate and the oblique flat steel, and then place the pressure Both sides of the plate and the oblique flat steel are welded longitudinally with the angle steel. The welding positions are relatively concentrated, and along the longitudinal extension of the angle steel, a large amount of heat generated by welding will cause the deformation of the angle steel, and subsequent correction of the angle steel is required to improve the safety of the civil air defense door. processing cost

Embodiment 1

[0026] like Figure 1-3 As shown, a civil air defense door processing device includes a frame 1, and longitudinal support rods 2 are fixed on both sides of the upper end of the frame 1. The longitudinal support rods 2 are rectangular rods, which are used to support the inverted angle steel 3, and the two longitudinal support rods are The frame 1 between the rods 2 is provided with an angle steel side end positioning mechanism. The angle steel side end positioning mechanism includes two, which are located at both ends of the longitudinal support rod 2 respectively. The hollow cylinder 4, both ends of the hollow cylinder 4 are provided with a mandrel 5, one end of the mandrel 5 is slidably placed in the hollow cylinder 4, and the other end is fixed with a top plate 6, and the upper end of the top plate 6 is provided with an inclined side near the longitudinal strut 2. On the downward guide surface, a compression spring 7 is arranged in the hollow cylinder 4 between the two eject...

Embodiment 2

[0029] This implementation is basically the same as Embodiment 1, except that: figure 1 and 2 As shown, the upper end positioning mechanism of the angle steel includes a horizontally moving side pressure plate 8 and a vertically lifting upper pressure plate 9, the upper pressure plate 9 is located just above the longitudinal support rod 2, and the lower end of the upper pressure plate 9 is provided with a pressure bearing plate 16 corresponding to the first plate 9. In the lower pressure groove 10 and the second lower pressure groove 11 corresponding to the inclined flat steel 17, the side pressure plate 8 is located on the side of the upper pressure plate 9 away from the top plate 6, and the side pressure plate 8 is used to press the bearing plate 16 laterally. The second lower pressure groove 11 is a V-shaped groove with its opening facing downward. One side of the V-shaped groove is in contact with the side of the oblique flat steel 17 away from the pressure bearing plate 1...

Embodiment 3

[0033] A kind of civil air defense door processing method that can reduce the amount of deformation, adopts the processing device shown in Embodiments 1 and 2, and comprises the following steps:

[0034] (1) A plurality of connecting plates 18 are fixed at the lower side between the bearing plate 16 and the oblique flat steel 17 along the longitudinal interval. One end of the connecting plate 18 is connected to the bearing plate 16 by welding, and the other end is connected to the oblique flat steel 17 by welding. ;

[0035] (2) Buckle the angle steel 3 upside down on the side of the longitudinal support rod 2 close to the top plate 6, the top plate 6 presses the side wall of the angle steel 3 on the longitudinal support rod 2, and the step (1) is connected to the pressure bearing by the connecting plate 18. The plate 16 and the inclined flat steel 17 are placed on the upper side of the angle steel 3, and the pressure-bearing plate 16 and the inclined flat steel 17 are pressed...

Abstract

The civil air defense door machining device comprises a machine frame, longitudinal supporting rods are arranged on the two sides of the upper end of the machine frame and used for supporting reversely-buckled angle steel, and an angle steel side end positioning mechanism is arranged on the portion, between the two longitudinal supporting rods, of the machine frame. An angle steel upper end positioning mechanism is arranged above the longitudinal supporting rod and used for pressing and positioning the bearing plate and the inclined flat steel to the upper side of the angle steel. The multiple connecting plates are fixed to the lower side between the bearing plate and the inclined flat steel at intervals in the longitudinal direction, the connecting plates are fixedly connected with the angle steel in a welded mode, the sides, away from the connecting plates, of the bearing plate and the inclined flat steel are fixedly welded to the angle steel, the welding positions are dispersed, and the connecting strength of the bearing plate, the inclined flat steel and the angle steel is guaranteed; and meanwhile, the problem that the angle steel is greatly deformed due to concentrated welding positions is also avoided.

Description

technical field [0001] The present invention relates to the technical field of air defense door processing, in particular to an air defense door processing device and method that can reduce deformation. Background technique [0002] The existing civil air defense door is usually four angle steel welded into a frame, and the pressure plate and the inclined flat steel are welded on the upper side of the angle steel. The longitudinal sides of the plate and the oblique flat steel are welded with the angle steel longitudinally. The welding positions are relatively concentrated, and along the longitudinal extension of the angle steel, a large amount of heat generated by the welding will cause the deformation of the angle steel. Follow-up correction of the angle steel is required to improve the air defense door. processing cost. SUMMARY OF THE INVENTION [0003] The invention proposes a civil air defense door processing device and method that can reduce the amount of deformation...
