MACHINE FOR COATING THE BASIS OF THERMOPLASTIC FACING MATERIAL

The utility model relates to the field of thermoplastic deformation and can be used for shaping the radius edges of plasticized furniture parts and other interior elements.

Known machine tool company Evans machinery (USA), designed for facing plastic rounded ends of the workpieces, which are the basis with a gluing material (plastic) glued on its flat surface. 1.

The machine includes a bed, a heater, a rocker arm, movably connected at one end to the bed, and the other to the heater, the clamping and forming elements.

The disadvantage of this machine is the relative complexity of its design and high cost.

Also known is a machine for coating the base with thermoplastic cladding material 2, including a bed, a heater, a rocker arm, movably connected at one end to the bed, and the other with a heater, clamping and forming elements, and the rocker is provided with a counterweight and is rigidly connected to the stop, the free end of which is provided with an adjusting bolt, and the forming element is rigidly connected to two-lever levers pivotally connected to the clamping element and installed equidistant from each other along its length, in addition, it is clamped th element is rigidly connected to the rod placed in a hollow rack

bed with the possibility of reciprocating movement in it with the help of a lever rigidly connected to the foot pedal located at the base of the bed.

The disadvantages of this design of the machine are low productivity, due to the fact that the raising and lowering of the clamping element is carried out manually and, in addition,

the design of the machine provides the plastic lining of the rounded end of the workpiece and its gluing to the base on one side. To carry out a similar operation on the opposite side of the workpiece, you must reinstall the latter.

The goal of the useful model is to increase

machine performance and ease of maintenance.

The problem is solved due to the fact that in the machine for coating the base with a thermoplastic facing material, including a bed, a rocker with a counterweight connected at one end to the heater, clamping and forming elements articulated between each other, the clamping element is made in the form of a frame consisting of two clamping beams associated with pneumatic cylinders, the beam is made in the form of a rotary frame connected via an axis to the clamping frame, in addition, the machine is equipped with a second forming element, pivotally connected m with a clamping beam.

The essence of the utility model is illustrated in the drawing, where

in FIG. 1.2 shows the inventive machine (front view and side view, respectively);

in Fig.3 - a workpiece with a plastic glued to a flat surface, in which a rounded end has not yet been formed;

figure 4 - the same workpiece during heating before the operation of thermal deformation;

biSiGJO-fi

figure 5 - the workpiece is formed at an angle rotor;

Fig.6 - blank, the end of which is formed with a double bend at an angle of 180.

The machine includes a bed 1, including a table 2, a rocker arm, made in the form of a rotary frame 3, on the racks of which on one side there is a rod 4, to which the heater 5 is suspended, and on the other, a counterweight (not shown). The rotary frame 3 is fixed on the axis to the clamping frame 6, containing two clamping beams 7 and racks 8 connected to the pneumatic cylinders 9. The clamping beams are pivotally connected to the forming elements, respectively 10 and 11.

The machine operates as follows.

Compressed air from the line enters through the air distributor to the piston cavities of the pneumatic cylinders 9. The piston rods are extended, the pressure frame 6 is lifted. In the initial state, the pressure frame 6 is in the upper position. The blank is placed on the table 2 beds. The workpiece is the base 12, the ends of which can be rounded at different angles. The drawing shows a workpiece, one end of which is rounded at an angle of 90, and the other is made with a double bend at angles of 90 ° and 180 °. On the flat surface of the workpiece, a facing material is glued - plastic 13, in which rounded ends are not yet formed.

After installing the workpiece by switching the air distributor, air is again fed into the rod cavities of the pneumatic cylinders, the clamping frame 6 is lowered and the product is clamped to the bed table. Then turn on the heater 5, carry out its preliminary heating, then set the time relay depending on the type of facing material and the heating temperature. 3

After this, by turning the frame 3, lower the heater 5 to the surface of the workpiece against the stops (not shown in the drawing). In this case, the time relay is turned on. After the timer for tripping is turned off, the heater 5 with the help of the rotary frame 3 returns to its original position, and the forming element is lowered onto the heated billet and kept in the lowered state until the plastic forms in the shape of the end face (20 - 30). Then the forming and clamping elements raise and remove the part from the table of the stands.

The claimed technical solution allows to increase the productivity of the machine, ease of maintenance and reduce the complexity of manufacturing the radius edges of plasticized parts.
