Description

Thermal welding device of window frame aggregate

The present invention relates to a thermal fusion device of a window frame aggregate, more specifically, in forming a window frame by thermally fusion bonding of the window frame aggregate made of a synthetic resin material, a plurality of window frame aggregates whose ends are cut at a predetermined angle are sequentially placed on the fusion machine. After control operation, clamping of each corner, melting and fusion bonding of adhesive surface are performed at each corner of the window frame at the same time to minimize the defective rate of the product due to warping or joining error. The present invention relates to a heat-sealing apparatus of a window frame aggregate, which can be automatically performed by a control system set according to the differential, thereby greatly improving work environment and improving workability and productivity.

Conventionally, the chassis that is used for window, that is, the window frame aggregate has been mainly used non-ferrous metal aluminum material, but recently, the synthetic resin window frame aggregate having excellent soundproofing and thermal insulation effect is preferred.

A window frame aggregate made of a synthetic resin material is generally formed by heat fusion of each corner portion and reinforcement portion.

In the past, many window frame aggregate heat fusion machines for fusion of the window frame aggregate made of the above synthetic resin have been proposed.

However, such a conventional window frame aggregate heat fusion machine is mostly composed of one or two clamping and fusion parts, the fusion and assembly work of the window frame using the same is very cumbersome and high maneuvering, so it can not escape the badness of the working environment, accordingly the product High defect rate and high workability and productivity have deteriorated, which in turn has been a major factor in increasing the supply cost of products.

The operation and use behavior of the clamping plate and the molten portion, which are structural features of these welding machines, are briefly described as follows.

First, in the case where the height adjustment of the clamping plate according to the height dimension of the window frame aggregate is made of the bolt assembly type, the height of the clamping plate must be adjusted arbitrarily by the operator while loosening and tightening the bolt with a separate tool when changing the dimensions. In addition to the delay of the work time required for adjustment, the cumbersome and difficult work of change coexists.

In addition, the hot plate for melting the window frame aggregate during heat fusion welding is to enter between the fixing surface of the fixed window frame aggregate to be melted, so that when the length of the window frame aggregate is long or short compared to the set dimensions, the molten portion of the window frame aggregate is not constant Therefore, a problem that greatly affects the melt strength of the joint surface was caused.

In addition, in some cases, a technique in which the clamping plate height adjusting part of the window frame aggregate is composed of hydraulic cylinders and pneumatic cylinders has been attempted. As a result, there remains a limiting factor in the inability to accommodate tall or thick window frame aggregates.

In addition, a technique is proposed in which an inclined moving plate is attached in parallel to the upper part of the vertical moving plate coupled to the vertical rail, and a fixed selector is attached to the rear surface of the inclined moving plate to selectively move the movable workbench vertically and inclinedly. However, it is structurally decisive and can not weld multiple window frame aggregates at the same time, and compared to the simple function of fusion welding the aggregate surface of aggregates, the structure is more complicated and difficult to use, so there are inherent problems of working environment. Deterioration, poor workability, and low productivity remain.

The present invention has been made in order to fundamentally solve and heal the general lung problems of the conventional window frame aggregate heat welding machine as described above has the following object.

The main object of the present invention is to form a window frame by thermal fusion bonding of the window frame aggregate made of synthetic resin, the end of the plurality of window frame aggregates cut at a predetermined angle on the fusion machine in order to control the clamping of each corner, It is an object of the present invention to provide a thermal fusion apparatus for window frame aggregate, which allows melting and fusion bonding of adhesive surfaces to be simultaneously performed at each corner of the window frame.

Another object of the present invention is to provide a thermal fusion device of the window frame aggregate to minimize the defective rate of the product due to distortion or coupling error, and the above manufacturing process is automatically performed by a control system that is differentially set according to the specifications of the product By doing so, it is possible to greatly improve the work environment, workability and productivity.

It is still another object of the present invention to provide a thermal welding device as described above to accommodate all irrespective of the size of the window frame aggregate, thereby significantly widening the working radius.

The operation process will be described in more detail below.

In the description, the front side is indicated by F and the rear side is indicated by B for the sake of understanding.

As shown in FIG. 1 and FIG. 2, when the operator presses the foot switch in the initial state in which the pallets 4, 5, 6 and 7 are collected, the transfer screw installed in the lower part of the movable rail 3 (11) is rotated by the power of the motor (M1), thereby causing the movable rail (3) is moved horizontally to one side on the first fixed rail (1) as shown in FIG. ) Is spaced apart by a predetermined distance between the.

At this time, the clamps 8a opposed to each other among the clamp assemblies 8 on the first and second fixed pallets 4 and 5 provided on the front side F of the second fixed rail 2 and the movable rail 3. ) And (8c) are moved to the front side (F) by the reverse operation of the cylinder, respectively, and the clamps (8a) and (8c) are the rails (41) by the contraction operation of the operation cylinders (S5) and (S6). ), Move to both sides along (51) to enlarge the workspace.

At this time, the heating plates 9 coupled to the outside of the clamps 8a and 8c are also simultaneously moved.

Next, the first and second movable pallets 6 and 7 provided on the rear side B of the second fixed rail 2 and the movable rail 3 move forward, respectively, and the respective clamps 8e, (8g) slides to the outside of each to secure the receiving space of the rear aggregate.

In this state, the window frame aggregate, which is both cut at an angle of 45 ° and is already cut off, is placed on the aggregate placement plate 30 of the rear clamps 8f and 8h of the movable pallets 6 and 7. At the same time, the reference piece 10 located below the inner space of the movable clamp assembly 8 is rotated about the hinge 10a axis by the operation of the cylinder S2 to be mounted thereon.

At this time, the lower surface of the standing surface of the rear clamps (8f), (8h) is pushed to the aggregate (T) to maintain a state where the cut surfaces of both ends of the aggregate piece abuts on each side of the reference piece (10), and at the same time The pressing plate 84 of the elevating assembly 81 is lowered, so that the support state of the rear aggregate is completed by the clamping operation in which the aggregate T is pressed against both ends.

In such a state, the outer clamps 8e and 8g pushed out of the movable pallets 6 and 7 are returned to their original positions, and the outer clamps 8b and 5 on the fixed pallets 4 and 5 are removed. 8d) and the placement plate 30 is maintained in a state in which they are mutually consistent to achieve a ready state in which both side aggregates can be placed.

At this time, the outer window frame aggregate which is located on both sides of the outer clamps (8b), (outer of the fixed pallets (4), (5) and the movable clamp assembly (8) of the movable pallets (6), (7) 8e), (8d) and (8g) are placed on each mounting plate (3) 0, and the lower surface of the aggregate is mounted on the auxiliary roller (40) which is located at the front side and rotates, respectively. The pressing plate 84 is lowered to clamp the aggregate.
