Description

Technical Field

[0001] This invention relates to a welding mold, and more particularly to a welding mold device for the hinge seat of a door panel of civil defense equipment. Background Technology

[0002] Civil defense equipment protective airtight door (hereinafter referred to as civil defense equipment door) is a type of civil defense equipment widely used in civil defense projects. The civil defense equipment door is mainly made by binding steel bars in the outer frame and pouring concrete in the outer frame. In addition, two hinge seats need to be welded on one side of the outer frame of the civil defense equipment door. The hinge seats are used to connect and fix with the external hinges.

[0003] The hinge base in the door leaf of heavy and large-sized civil defense equipment requires special design, such as Figure 1 The hinge seat includes a base plate 41, a partition plate 42, and three reinforcing square tubes 43. The partition plate 42 is welded to the end face of the base plate 41, and the reinforcing square tubes 43 are welded to the end face of the partition plate 42. The partition plate 42 is located between the base plate 41 and the reinforcing square tubes 43, and both the end face of the base plate 41 and the end of the reinforcing square tubes 43 extend beyond the outside of the partition plate 42. The gap between the end face of the base plate 41 and the end of the reinforcing square tubes 43 forms a gap for clamping the edge of the outer frame of the door leaf of the civil defense equipment. The hinge seat also has through holes 44 for fixing with external hinges. The through holes 44 pass through the base plate 41, the partition plate 42, and the reinforcing square tubes 43 in sequence. Currently, welding the hinge seat can only be done by manually marking and arranging the parts by workers, and finally completing the welding work. However, the existing technology requires the use of various positioning tools to complete the welding work of the hinge seat, and the parts need to be moved between the positioning tools multiple times. The positioning process is complicated and the positioning is inaccurate. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a welding mold device for the hinge seat of the door leaf of civil defense equipment with reasonable structure and accurate positioning.

A positioning groove extending to the left side wall of the first positioning block is opened on the upper end face of the first positioning block. The outline of the positioning groove matches the outline of the right side of the partition of the hinge seat. The horizontal height between the bottom of the positioning groove and the upper end face of the main positioning seat matches the thickness of the bottom plate of the hinge seat. The side wall of the bottom plate of the hinge seat can abut against the left side wall of the first positioning block. A second positioning block is fixedly connected to the rear part of the upper end face of the main positioning seat. The rear side wall of the bottom plate of the hinge seat can contact the front side wall of the second positioning block. The punching positioning plate is hinged to one side of the main positioning seat, and the punching positioning plate has several sample punching holes. The square tube positioning frame is hinged to the other side of the main positioning seat. The square tube positioning frame is provided with a square tube positioning slot, and the inner sidewall of the square tube positioning slot matches the placement position of several reinforcing square tubes of the hinge seat.

[0006] As a preferred embodiment of the welding mold device for the hinge seat of the door leaf of the personal protective equipment, the square tube positioning frame is fixedly connected to a third positioning block, the height of which is consistent with the sum of the thickness of the bottom plate and the partition plate of the hinge seat.

[0007] As a preferred embodiment of the welding mold device for the hinge seat of the self-defense equipment door, the front side wall of the third positioning block of the square tube positioning frame contacts the rear side wall of the second positioning block of the main positioning seat.

[0008] As a preferred embodiment of the welding mold device for the hinge seat of the door leaf of the personal protective equipment, a fourth positioning block is fixedly connected to the rear edge of the main positioning seat, and the fourth positioning block and the second positioning block form a gap that can only accommodate the third positioning block of the square tube positioning frame.

[0009] As a preferred embodiment of the welding mold device for the hinge seat of the self-defense equipment door, the end face of the punched positioning plate is provided with a positioning protrusion, the height of the positioning protrusion matches the thickness of the bottom plate of the hinge seat, and the side wall of the bottom plate of the hinge seat can abut against the side wall of the positioning protrusion.

[0010] With this structure, the bottom plate of the hinge seat is placed on the main positioning seat with the back side facing up. The first and second positioning blocks are used to position the bottom plate of the hinge seat. The punching positioning plate is flipped over and placed horizontally on the upper side of the bottom plate of the hinge seat. A hand drill is used to punch holes along the four punching holes. The punching positioning plate is flipped back to its initial state. The bottom plate of the hinge seat is then placed on the main positioning seat with the front side facing up. A partition is placed on the bottom plate. The partition is positioned by the positioning groove of the first positioning block and the fourth positioning block. The partition is then welded to the bottom plate. The square tube positioning frame is rotated to the upper side of the partition of the hinge seat. The three reinforcing square tubes of the hinge seat are placed in the square tube positioning groove of the square tube positioning frame. The partition is then welded to the three reinforcing square tubes. This completes all the welding and forming processes of the hinge seat.

[0011] The beneficial technical effects of the hinge seat welding mold device for the door leaf of the security equipment are as follows: the positioning process is simple, the mold device can achieve precise positioning, the welding steps are standardized, the requirements for the skill level of workers in the welding operation of the hinge plate are reduced, and the punching and welding processes can be realized by the hinge seat welding mold device for the door leaf of the security equipment, without the need for multiple handling between multiple positioning tools, thus improving work efficiency.
