Description

J1

The invention relates to the welding of plastics, namely the welding of plastic pipes with fittings, and can be used for welding sewer or other wiring

The aim of the invention is to expand the technological capabilities of the device by providing welding of pipe wiring of various configurations

Figure 1 shows a device in general view; in FIG. 2 is the same, a top view in FIG. 3 is a view along arrow A in FIG. 1; figure 4 is a view along arrow B in figure 1.

The device for the resistance welding of thermoplastics pipes contains a frame 1, on guides 2 of which clamps are clamped, clamps 3 and 4, in which fittings (tees, elbows, elbows) and a pipe with a shaped part welded to it are attached, mechanism 5 moving and compressing the pipes, the heating element 6. The clamping clamp 4 is made integral, the parts of which are interconnected with the possibility of movement by means of a link 7 and-fixation using clamps 8 and 9. One of the parts is made in the form of a bracket 10, on axis 11 of which a rotatable lockable lodgement 12. The lodgement 12 having the grooves 13 is pressed against the bracket 10 by the spring 14 and fixed on the mounting fingers 15. The grooves 13 are located on both sides of the lodgement 12. The bracket 10 is supported on the rod 16 and is able to move freely along it .

The device operates as follows.

The shaped part 17 is clamped in the clamping clamp 3, and the pipe 8 with the shaped part welded to it is installed in the clamping clamp 4, made integral. To fix the shaped part of the pipe 18 relative to the shaped part 17 fixed in the clamping clamp 3, a bracket 10 resting on the rod 16 is brought in and the shaped part of the pipe 18 is installed in the grooves 13 of the tool tray 12, after which the pipe 18 is clamped in the clamp 4. The clamp 9 bracket 10 is rigidly fixed from

relative to the rod 7, which is connected to the clamping collar 4 of the clamp 9. Then the heating element is lowered into the working position by the mechanism 5 for moving and compressing the pipes, the clamping clamps 3 and A are brought down to completely cool the welded parts into the heating element 6 to melt them. In this case, by means of the link 7, the lodgement 12, mounted on the bracket 10, moves together with the clamping clamp 4, clearly fixing the position of the shaped part of the pipe 6. After the necessary exposure of the parts in the heating element 6, the clamping clamps 3 and 4 are opened, the heating element 6 is withdrawn from working position. Then, the clamping clamps 3 and 4 are reduced until the molten pipe 18 fully enters the socket of the shaped part 17. Welding of the parts takes place. After the necessary exposure, the clamping clamps 3 and 4 open and remove the welded wiring. For fixing pipes with shaped parts of various configurations of different lengths and at different angles, lodgement-1 has the ability to rotate relative to the bracket 10 on the axis 11 and be fixed with the mounting fingers 15, and the bracket 1 can be restored relative to the clamping part of the clamp 4 by the required distance rods 7 and secured with clamps 9.

Claims (1)

The claims The DPJ device for the resistance welding of thermoplastics pipes, containing a frame, guides on which it is movable. but clamping clamps, a mechanism for moving and compressing pipes and a heating element are fixed, except for the fact that, in order to expand technological capabilities by ensuring welding of pipe wiring of various configurations, one of the clamps is equipped with a bracket fixed to the xoNryTe, a bracket mounted} with a possibility of longitudinal movement and fixation, and a lodgement for pipe routing, fixed with an axis of the bracket with the possibility of rotation and fixation, .  8 1 & 7 Figure 1 FIG 2 View/ Widb IS FIG 3  Compiled by L.
