Embodiment Construction

[0022] A method for manufacturing a curved surface structure of a door frame corner or a window frame corner, such as image 3 shown, including the following steps:

[0023] a. Use the central axis of the circular tube or rod-shaped material as the center of rotation to locate, perform machining such as turning, milling or grinding, and process it into a circular horn-shaped hyperboloid component 4;

[0024] b. Then the circular trumpet-shaped hyperboloid part 4 is cut into 4 parts in the radial direction, which is the commonly used door frame corner or window frame corner 2;

[0025] c. Use the four cut door frame corners or window frame corners 2 at the four corners of the door or window 1 to form a door frame or window frame by welding.

[0026] The above-mentioned embodiments should be understood that these embodiments are only used to illustrate the present invention more clearly, and are not intended to limit the scope of the present invention. After reading the present...

Abstract

The invention discloses a manufacturing method of a door or window frame angle curved surface structure. In order to solve the problem of high machining difficulty or high cost of a conventional door or window frame angle, the manufacturing method of the door or window frame angle curved surface structure comprises the following steps of: a. positioning by taking the central axis of a circular rod or a circular tube as the center of rotation, and machining the circular rod or the circular tube into an annular trumpet-shaped hyperboloid part; b. cutting the annular trumpet-shaped hyperboloid part into four equal door or window frame angles along the radial direction; and c. welding the cut door or window frame angles in corners of a door or window frame. According to the manufacturing method, the manufacturing difficulty and cost of hyperboloid structures can be significantly reduced.

Description

technical field [0001] The invention relates to a method for manufacturing a curved surface structure of a door frame corner or a window frame corner. Background technique [0002] Many windows and doors in existing locomotives and vehicles have rounded corners, and some of the rounded corners are made by special molds. Forming of single- and double-curved tempered glass for automobiles; the single- and double-curved glass forming pressing mold includes a base, several connecting pieces connected to the base and several drooping spokes made according to specific parts of the glass. Dropped spokes are secured to corresponding connectors. Since several drooping spokes of the single- and double-curved glass forming and pressing molds of the present invention apply pressure to specific parts such as the difficult-to-form parts of the glass frame or the parts that have certain requirements on the curvature of the curved surface, the glass is formed, so the single- and double-cur...
