2. Description of the Related Art As a fusion machine used for connecting synthetic resin piping materials, for example, a pipe and a joint are respectively held by a pair of clamps, and the joint surfaces of the pipe and the joint (the outer surface of the pipe end and After the inner surface of the joint) is heated and melted using the heater face, the relative movement of each clamp brings the pipe and the joint closer to each other, bringing the joint surfaces (melting parts) into contact and fusing. There is a structure of joining (for example, Japanese Patent Laid-Open No. 61-254332).

By the way, according to the fusion machine of this kind, in order to always obtain a stable joint strength, from the time when the joint surface of the pipe material is heated and melted until the respective joint portions are brought into contact with each other. The time must be short and constant. However, according to the former fusion machine described above, since the backward and forward movements of the clamps are performed manually (handle operation), the backward movement of the clamps is followed by the backward movement of the clamps (withdrawing the heater face of the piping material) There is a problem in that the time required for the clamp advancement (joining) process varies greatly each time joining is performed, and thus the reliability of the joining strength is poor.

On the other hand, according to the latter fusion machine, since the clamp moves automatically, the time from the above-mentioned drawing step to the joining step can be made constant at all times, but the pipe material having a small diameter is used. The joining conditions when making the connection are poor.

That is, since the stop position of the clamp at the time of retreating is usually set in accordance with the pipe material having the maximum diameter, when connecting the pipe material having a small diameter, an extra amount is required from the end of heating and melting to the joining. It takes a long time, and in addition to this, since the piping material having a small diameter is thin, the melting surface is easily cooled, and as a result, the joining state deteriorates.

A structure for achieving the above-mentioned object will be described with reference to FIGS. 1 to 3 corresponding to an embodiment. The pipe P and the joint J are respectively provided to a pair of clamps 2 and 3 which are arranged and are capable of relative movement in directions toward and away from each other.
While holding and, the respective joint surfaces are heated and melted by the heater 4 arranged between the pair of clamps, and then the respective clamps 2 and 3 are retracted and the heater 4 is moved from between the clamps 2 and 3. After the removal, the clamps 2 and 3 are moved toward each other to move the pipe P
In the fusion machine having a structure in which the fusion joint and the joint J are brought into contact with each other, the stop means (for example, the limit switch 2L, the limit switch 2L, 3L and the control circuit 5 of the hydraulic control system of the cylinders 20 and 30) are provided, and the stop means thereof respectively set the distances of the stop positions of the clamps 2 and 3 to the heater 4 arrangement position in the heating step.

The distance between the clamps 2 and 3 when retracted by the stopping means, that is, the time from the end of heating and melting of the pipe material to the joining is always constant. Moreover, since the stop positions of the clamps 2 and 3 at the time of retreating can be changed according to the caliber size of the pipe material to be connected, the time required for the retreat of the clamps can be minimized for each caliber size. This makes it possible to minimize the cooling of the joint surface (melting surface) of the piping material even when the diameter size is small.
