Abstract

PURPOSE:To prevent the generation of burs checking thermal influence on others than weld parts by making the weld parts opposite to each other through a specified space to melt them with a radiation heat of a heater positioned at an intermediate position set for a specified interval. CONSTITUTION:Weld members 1 and 2 made of a thermoplastic resin are fixed on bases 20 with pressure holders 3 and 4 with the weld surfaces 1a and 2a opposite to each other. A specified space is formed between both the weld surfaces and a heat radiation heater 5 is arranged at the center thereof. The plane of the heater 5 is almost the same in the shape as the weld surfaces. The weld surfaces 1a and 2a are heated and melted simultaneously with the heater 5 risen to a specified temperature. Then, the heater 5 is removed, the weld surfaces 1a and 2a are pressed, held and joined together quickly with pressure holding jigs 3 and 4. Thereafter, the pressing and holding are released to complete the joint.

溶接法はノズルより熱風を溶接箇所に吹きつけて溶接を
行なう方法であるが、この方法だとノズルより吹き出さ

り、熱風の対流により溶接部以外の箇所に熱影響が及び
、被溶接部材が変形、変質したりするという問題がある
。Conventionally, when welding thermoplastic resin members, it is common to use hot air welding or hot plate welding. The hot air welding method is a method of welding by blowing hot air from a nozzle onto the welding area, but with this method, the pressure of the hot air blown out from the nozzle may create wavy irregularities on the surface of the welding area, or the convection of the hot air may cause welding. There is a problem in that heat affects areas other than the welded part, resulting in deformation or alteration of the welded member.

一方、熱板溶接法は、溶接箇所に熱板を溶接させて被溶
接部材を溶接させ結合させる方法であるが熱板を溶融箇
所から引き離す際、溶融樹脂が熱板から完全に離れず糸
を引くという現象が生じる。On the other hand, hot plate welding is a method in which a hot plate is welded to the welding point to weld and join the parts to be welded, but when the hot plate is pulled away from the molten spot, the molten resin does not completely separate from the hot plate and the threads are removed. A phenomenon of pulling occurs.

つまり繊維状のハリが生じるという問題がある。In other words, there is a problem in that fibrous firmness occurs.

〔発明の目的〕[Purpose of the invention]

本発明は上記問題点に鑑みて案出されたもので、溶接層

The figure shows a state in which the radiant heater 5 is attached to the pressure holding jigs 3 and 4, and a state in which the temperature of the thermal radiation heater 5 is raised by the control power source 6 and the state is waiting for heating. At this time, the surface temperature of the heater 5 is measured by an infrared radiation thermometer 7, and is constantly controlled to a target value through feedbanking by a control power source 6.

The heating time is preferably 5 seconds to 30 seconds. Also, the first and second
In order to simultaneously melt the welding surfaces 1a and 2a to the same extent, the heater 5 is located approximately at the center of the predetermined interval 11. Next, as shown in FIG. 4, the heater 5 is removed and the pieces are quickly pressed and held using the pressure holding jigs 3 and 4 to join them. The pressing force F at this time varies depending on the material and shape of the welding member, but is 0.5 kg f~5 per 1 d of joint area of the member.
kg f is good, and holding time is good between 8 seconds and 40 seconds. Alternatively, a method of crushing to a certain size may be used. After that, the pressing and holding are released to complete the bonding.

ものではない。FIG. 5 shows another modification, in which it is also possible to weld a multi-tank having partition walls. This welding involves simultaneously welding the outer circumferential welded portions 1b and 2b of the first welded member 1 and the second welded member 2, and the partition wall portions 1c and 20. In this case, the planar shape of the thermal radiation heater 5 is preferably divided into a first heater 5a and a second heater 5b as shown in FIG. It's not something you can do.
