Abstract

The invention discloses a floor heating pipeline groove forming method, and relates to the field of forming combination molds special for floor heating pipeline grooves. The floor heating pipeline groove forming method includes the following steps that (1) a mold is installed; (2) feeding is performed; (3) stamping is conducted, two forming blocks are subjected to acting force of a heat conduction layer blank and can rotate towards the middle part to be folded synchronously under the combined effect of compressed springs at the two sides of a lower mold base and a supporting spring at the bottom of a U-shaped groove, and a protruding part can be wrapped by bending the heat conduction layer blank; and (4) resilience is carried out, the protruding part can enter the gap located between the two forming blocks completely when an upper mold reaches the maximum stroke, and the heat conduction layer blank can wrap the protruding part completely; and then, the two forming blocks rotate towards the two sides to be separated synchronously, and the heat conduction layer blank can be ejected out. By means of the floor heating pipeline groove forming method, the function of precisely processing the floor heating pipeline grooves at a time in a wrinkle-free mode is achieved, and dimensional consistency of the floor heating pipeline grooves in the length direction is guaranteed.

Description

[0001] The patent application of the present invention is a divisional application with the application number: 2015107913848. The filing date of the original application is: 2015-11-16. The name of the invention is: a combined mold for forming floor heating pipe grooves and its forming method. technical field [0002] The invention relates to the field of special forming composite molds for floor heating pipe grooves, and more specifically relates to a forming method for floor heating pipe grooves. Background technique [0003] Floor heating has become the mainstream of domestic heating methods, but the traditional installation method of floor heating is called wet floor heating. High, the thermal effect time is very long, accounting for about 10 centimeters of the building's floor height, and it has a large load on the building. Aiming at the many shortcomings of the wet floor heating technology, dry floor heating technology products have emerged in recent years, namely dr...
