CN2721836Y - Built-in steel lining breach with V-shaped mouth welded plastic door and window - Google Patents

Abstract

The utility model discloses a built-in steel lining cutting notch for welding V-shaped openings of plastic doors and windows. The utility model solves the technical problem that firstly, a steel lining 2 is penetrated in the inner cavity of a profile 1 when a V-shaped opening welds a middle rail in the process of the processing and the manufacture of plastic doors and windows, weld can not be carried out, and the steel lining 2 can be penetrated in the steel lining 2 when the V-shaped opening is in butt welding. The utility model has the technical proposal that a notch is also cut on a corresponding site of the steel lining 2 on the site where the V-shaped opening is cut by the plastic profile 1 so as to that the steel lining 2 is fixed on the plastic profile 1 before the V-shaped opening is welded, and weld can not be affected. The utility model has the main use that the notch is cut on the V-shaped opening site corresponding to the steel lining 2 for door and window frames with V-shaped opening weld in the process of the processing and the manufacture of plastic doors and windows so as to that the steel lining 2 can be fixed before the V-shaped opening is welded, and weld can not be affected. Additionally, the utility model can continuously work on automatic blanking cutting centers and automatic welding angle removing line connecting machines. The utility model has the advantages of simple welding procedure of the V-shaped opening, high work efficiency and low production cost.

Description

Wear steel lining incised notch mouth in the welding of plastic door-window V mouth

Technical field the utility model relates to the plastic door-window in the building trade, more particularly, and V mouth solder technology when the utility model relates to the plastic door-window making.

The intensity of background technology PVC plastic irregular profile own is low, be made into plastic door-window, must penetrate steel lining at the inner chamber of plastic material, and with screw, to improve the intensity of plastic door-window, improves the resisting wind press capacity of plastic door-window.In ORIENTED DOOR AND WINDOW DESIGN, often be designed to have the pattern of stile in horizontal V mouth welding or the vertical V mouth welding.Promptly penetrate steel lining if only section bar has been cut the V mouth, promptly have the part steel lining to exceed the V mouth tip of profile shapes, cause the weldering plate can't insert molten molten profile shapes in profile shapes V notch portion.The technology of therefore prolonging usefulness at present is, profile shapes blanking → cut V mouth → penetrate steel lining → elder generation make a call to a hole for the expansion bolt → wear pin steel lining and profile shapes are fixed together (prevent the dislocation of profile shapes and steel lining and other hole for the expansion bolt is beaten in influence) → beat the V mouth welding machine location → weldering plate insertion V mouth of all the other hole for the expansion bolts → extraction steel lining → upward melt molten → weld plate and mention butt welding → penetrate steel lining → beat steel lining to follow closely fixedly steel lining.

Summary of the invention the utility model has solved and has penetrated the technical barrier that can't weld the V mouth after steel lining is fixed earlier, a kind of simple and practical method is provided, present V mouth welding sequence is simplified greatly, on steel lining, cut out in advance breach, realize that blanking → cut V mouth → wear steel lining → beat steel lining is followed closely fix → to beat hole for the expansion bolt → V mouth welding sequence flow process.Thereby realized in the automatic blanking cutting, processing in the heart the V mouth and welded the purpose of welding clear angle on the line machine of clear angle automatically.

The purpose of this utility model is achieved by following technical proposals:

The U-shaped steel lining is made breach according to the position of V mouth welding, penetrate blanking by drawing then and cut out in the inner chamber of plastic irregular profile of V mouth, and be screwed, make the steel lining breach be lower than the tip of profile shapes V mouth at the V of profile shapes mouth place, then can be on V mouth welding machine or 6 welding machines welding fabrication once.

Above-mentioned steel lining incised notch mouth is to cut out breach on two opposed side edges of U-shaped steel lining, and the base of steel lining breach is lower than the tip of section bar V mouth.

The beneficial effects of the utility model are:

1, solve present V mouth welding sequence and must when the butt welding of the molten molten back of V mouth, just can wear steel lining, can not in the automatic blanking cutting, process the V mouth in the heart, can not be at the technical barrier that welds welding V mouth on the line machine of clear angle automatically.

2, it is easy that steel lining is made the V mouth, and the design specialized mould utilizes plant equipment such as punch press or other forcing press to be stamped to form.

3, existing operation is simplified, saved man-hour, increase work efficiency, reduce production costs.

4, realized the blanking that on automatic blanking cutting center door and window makes → cut V mouth → wear steel lining → play the steel lining nail fix → to beat hole for the expansion bolt the automatic clear angle line machine welding fabrication that welds of commentaries on classics.

Description of drawings Fig. 1 is that plastic material 1 blanking processes the steel lining 2 that will not cut out breach behind the V mouth and penetrates plastic material 1 inner chamber, there is small part steel lining 2 to exceed in the V of plastic material 1 mouth tip, makes weldering plate 3 can't insert the V mouth simultaneously to the schematic diagram of plastic material 1 and plastic material 4 heating.

Fig. 2 is the utility model elevation and sectional view (steel lining cuts out the shape of breach).

Fig. 3 is a schematic diagram of the present utility model.

The specific embodiment is described in detail the utility model below in conjunction with accompanying drawing.

Require the position open the V mouth according to the door and window drawing, the relevant position of steel lining 2 is also cut out breach, the steel lining 2 that cuts breach is penetrated the inner chamber of the plastic material 1 that cuts the V mouth, and be screwed.At the V of section bar 1 mouth place, the breach of steel lining 2 is lower than the V mouth tip of plastic material 1.At this moment weld in the V mouth that plate 3 can be inserted into section bar 1 smoothly, under the promotion of horizontal pressure force, the tight-lipped back that is pressed in weldering plate 3 of the V of section bar 1, the V-type head of middle stile 4 is pressed on the belly of weldering plate 3, weldering plate 3 is simultaneously to section bar 1 and 4 heating of middle stile, be heated to after the regular hour weldering plate 3 by technological requirement and extract out, section bar 1 and in stile 4 under horizontal pressure force promotes, carry out the butt welding moulding.

Claims (2)

1. wear steel lining incised notch mouth in a plastic door-window V mouth welding, it is characterized in that, cut out breach on two opposed side edges of U-shaped steel lining (2), the inner chamber that penetrates section bar (1) again is also fixing, and does not influence the welding of V mouth.

2. according to wearing steel lining incised notch mouth in the welding of the described plastic door-window V of claim 1 mouth, it is characterized in that the breach base that steel lining (2) cuts out is lower than the tip of the V mouth that cuts out on plastic material.
