TH69333B - Welding method for resin molding - Google Patents

Abstract

Welding method for resin workpieces Which when the welding head (4) of the ultrasonic welding machine has been To the tip surface of the first component (1), the outflow of the molten material from the outer edge And the inner edge will be able to prevent That is to say, make the step part (3) on the tip surface (1a) of the first component (1) and keep the convex tip (1b) within the step part (3).

Disclaimer (all) which will not appear on the advertisement page: Amendment 31/08/2018 Disclaimer 1. Welding method for resin forming work is a bonding method of bonding together of The first (1) and the second (2) components, each of which is obtained by machine-made resin molding. Ultrasonic welding Where the end surface (1a) perpendicular to the axis of the first component (1) is molded. It has an approximate annular plane surface and a convex portion (1b), slightly protruding from that plane surface. They are far apart and radially distributed per axis. With multiple numbers on that plane surface And contains In the construction process, prepare the (3) ring-shaped steps that are concave to the surface of the plane that At least one side of the outer or inner edge of the said end surface (1a) and bonding process. Which makes the first (1) component and the said second (2) component in contact. The welding head (4) of the welding machine comes into contact with the said end (1a) surface of the first (1) component and causes ultrasonic vibration between the first (1) component and the The second (2) component, while the multiple convex (1b) and the multiple convex (1b) components are pressed against the plane surface by vibration. With ultrasonic and is basically the same as the plane surface. Along with the deformation of each convex section (1b), the resin fused from the tip of the convex (1b) trapped the step (3) and the resin fused from the tip of the segment. Convex (1b) does not protrude strongly. At least one side of the outer or inner edge, along the radius from at least one side of the outer edge or edge The inside of the end surface of the first component (1) ---------- 1.Welding method for the first (1) and second (2) components of the resin molded parts, respectively, which were formed through the resin molding with an ultrasonic welding machine. It consists of: the process of forming the end surface (1a) intersecting with the axial line of the first component (1) to have an annular plane surface and several convex sections (1b) emerging slightly from that plane surface. By away Together and distribute radial to the said axis And the construction of the steps (3) in the shape of the concave ring Such a plane surface at least one side of the outer edge and the inner edge of such end surface (1a); This causes the first (1) and second (2) components to come into contact with each other, and the welding torch (4) head (4) into contact with the end surface (1a) of the first component (1) causes vibration. This is done by ultrasonically with one (1) component and compresses each of the convex sections (1b) to the Level with the plane surface, and from the distortion it is welded by giving The resin loosens from the convex tip (1b), locks itself at the stepped part (3) and causes the resin looseness from the convex tip (1b) not protruding at least one side of the outer and inner radial. From at least one side of the edge Outside and inside edge of the end surface (1a) of the first component (1). 2. The welding method for resin molding described in claim 1, which has specific characteristics as follows: One (1) component is the radiator valve housing. The second (2) component above is the radiator cap housing. Make the aforementioned steps (3) in a ring shape along the outer edge. And the inner edge of the end surface (1a) of the first component (1) of the valve housing.
