Description

A kind of box-like metal door leaf

Technical field

The utility model relates to door, is specifically related to a kind of box-like metal door leaf.

Background technology

Existing metal door processing adopts door leaf plate to add steel in-seam usually, be shaped rear surrounding steel edge sealing welding, the surrounding edge sealing of labeled door also need indentation groove for pasting the anti-plume of bulging, the shortcoming of said method processing metal door leaf mainly contains: manufacturing procedure is many and complicated, need various processing equipment, working (machining) efficiency is low; The connection of door leaf two panels, based on electric welding, can cause unnecessary environment pollution, simultaneously high to the skill set requirements of processing staff, possible solder joint leak outside impact attractive in appearance; Because having independently in-seam and edge sealing parts, cost of production is high, and in process, difficult quality controls; Door leaf interior fill space is complicated, and filler is difficult to accomplish that bulk is filled, and easily forms empty gap between filler and in-seam, and the outward appearance namely affecting door leaf obviously more affects the fireproof performance of labeled door.

Utility model content

It is simple that the purpose of this utility model is to provide a kind of structure, the box-like metal door leaf of durable fire prevention.

In order to achieve the above object, the utility model has following technical scheme:

The box-like metal door leaf of one of the present utility model, comprise inner side door leaf, outside door leaf, described inner side door leaf and described outside door leaf withhold formation box-like body by bending, and inner side door leaf is relative with the bending stile lap-joint hole of outside door leaf, steel rivet is fixed through hole, be filled with door panel in box-like body, the medial surface of described inner side door leaf and described outside door leaf is provided with fire prevention glue-line.

Further, the bending stile of described inner side door leaf and outside door leaf is all in step bending.

Further, the bending stile of the step bending of inner side door leaf and outside door leaf is stacked formation groove, and this groove is provided with ornamental strip or the anti-plume of fire prevention expansion.

Further, five metals stiffener is provided with inside the bending stile lap-joint of inner side door leaf and outside door leaf.

Further, the stiffening frame in triangular shape is provided with in described door panel.

Owing to taking above technical scheme, the utility model has the advantage of that manufacturing procedure is few, technique is simple, and save material, cost of production is low; Easily quality control is realized in process, reduce the use of electric welding machine, reduce the dependence (needing to hold job that requires special skills certificate without the need to operating personnel) to the skill set requirements of operative employee, reduce the environment pollution that welding machine causes, accomplish that no-welding-spot leaks outside appearance effect simultaneously, the more important thing is that this processing method is processed for labeled door, the filling density of anti-fire door core board can be strengthened, more can improve the fireproof performance of labeled door.

Detailed description of the invention

Below implement for illustration of the utility model, but be not used for limiting scope of the present utility model.

See Fig. 1, the box-like metal door leaf of one of the present utility model, comprise inner side door leaf 6, outside door leaf 1, inner side door leaf 6 and outside door leaf 1 withhold formation box-like body by bending, and inner side door leaf 6 is relative with the bending stile 10 lap-joint hole of outside door leaf 1, steel rivet 5 is fixed through hole, is filled with door panel 3 in box-like body, inner side door leaf 6 is provided with the medial surface of outside door leaf 1 glue-line 2 of preventing fires, and the bending stile 10 of inner side door leaf 6 and outside door leaf 1 is all in step bending; Inner side door leaf 6 is stacked formation groove with the bending stile of the step bending of outside door leaf 1, and this groove is provided with ornamental strip or the anti-plume 7 of fire prevention expansion; Five metals stiffener 4 is provided with inside the bending stile lap-joint of inner side door leaf 6 and outside door leaf 1.

The processing method of box-packed door leaf, comprises the steps:

1, the processing of outer side panel in box-like door leaf

First by steel plate through shear, rush corner breach, lockhole, hinge breach, staking ailhead counterbore, bender is utilized to carry out surrounding bending, form boxlike shape, on the stile at the boxlike door leaf plate corner of bending and forming and hinge breach and lock body installing hole place, just can spray treatment after itself and five metals stiffening plate being connected and fixed by butt-welding machine or puncture rivet technique.

2, door leaf assembling is shaped

First the medial surface of the inner panel of door leaf plate is scraped upper Waterproof gum, fill out the door panel that preprepared size dimension is suitable, buckle the door leaf outer side panel that medial surface has scraped glue again, make door leaf outer side panel inside and outside the pull-up manufactured head counterbore of the bending facade of inner panel together with lapping, and holes is just in time relative, the optional holes of surrounding correspondence position of door leaf pull on steel rivet fixing after, be put into pressurize sizing in door leaf press.

3, door leaf is shaped and reinforces

After the complete solidifying and setting of door leaf assembly welding Waterproof gum, door leaf is taken out in pressure-maintaining machine, do not fix counterbore place with rivet all fix remaining for door leaf surrounding with steel pulling rivet, have the position steel pulling rivet of five metals stiffening plate to pass five metals stiffening plate and fix together.

4, door leaf packaging

Check out the door leaf reinforced with or without after other quality problems, along door leaf surrounding by the groove on the bending surrounding stile of interior outside leaf plank, ornamental strip (as labeled door then pastes the anti-plume of fire prevention expansion) in stickup, the steel staking ailhead of such door leaf surrounding is just ensconced in ornamental strip, carries out next step and normally packs.

Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give exhaustive to all embodiments.Every belong to the technical solution of the utility model the apparent change of extending out or variation be still in the row of protection domain of the present utility model.
