Sweat soldering apparatus

Abstract

The invention discloses a sweat soldering apparatus, comprising a frame. Two clamping assemblies are symmetrically mounted on the frame along a horizontal direction in a sliding connection manner; a switching assembly is mounted above the clamping assemblies and is installed on the frame by means of bearing connection; the switching assembly is provided with a heat melting plate and a fixed ring which face each other; and the switching assembly provides power for position switching of the heat melting plate and the fixed ring. Through the arrangement of the fixed ring, the sweat soldering apparatus of the invention prevents a melted part from overflowing to two sides during mutual extrusion of two vacuum tanks and also prevents airtightness defects occurred in enclosure of two chambers; and since fixed clamp blocks are arranged, the positioning of the vacuum tank is facilitated and accurate butt joint of the welding interfaces of the vacuum tanks is ensured, thereby ensuring welding quality.

Description

technical field [0001] The invention relates to the technical field of welding devices, in particular to a hot melt welding device. Background technique [0002] With the development of the automobile industry, the technology of the braking system has developed very mature. The safety and stability of the braking system has always been the most important criterion for measuring the braking system. The safety and stability of the braking system cannot be separated from the braking system. The quality of the parts, in the booster function of the automobile brake system, there is a vacuum tank that provides positive and negative pressures. The current method of combining the upper cavity and the lower cavity of the injection vacuum tank mainly uses hot plate welding, but the upper cavity and the lower cavity All adopting hot plate welding will cause the molten engineering plastics on the upper cavity and the lower cavity to overflow to both sides, which will cause airtight defe...

[0002] With the development of the automobile industry, the technology of the braking system has developed very mature. The safety and stability of the braking system has always been the most important criterion for measuring the braking system. The safety and stability of the braking system cannot be separated from the braking system. The quality of the parts, in the booster function of the automobile brake system, there is a vacuum tank that provides positive and negative pressures. The current method of combining the upper cavity and the lower cavity of the injection vacuum tank mainly uses hot plate welding, but the upper cavity and the lower cavity The use of hot plate welding will cause the molten engineering plastic on the upper cavity and the lower cavity to overflow to both sides, which will cause airtight defects after the upper cavity and the lower cavity are combined.
