Abstract

The invention discloses a method for manufacturing a floor heating pipeline groove forming combination die, and relates to the field of forming combination dies special for floor heating pipeline grooves. The method comprises the following steps of (1) blanking, (2) forging, (3) rough machining, (4) punching, (5) thermal treatment and (6) finish machining. According to the structure of the die, a U-shaped groove is formed in a lower die holder, and two forming blocks are arranged in the U-shaped groove in a bilateral symmetry mode. Side through holes are symmetrically formed in the two sides of the lower die holder, bolts penetrate through the side through holes to be in threaded connection with the forming blocks and are sleeved with compression springs, and the diameter of the compression springs is larger than the inner diameter of the side through holes. A placing groove is formed in the center of the bottom of the U-shaped groove, and a supporting spring is mounted in the placing groove. The floor heating pipeline groove forming combination die manufactured by the method achieves the functions of integrally machining floor heating pipeline grooves precisely with no wrinkles on the floor heating pipeline grooves, and guarantees the dimension consistency of the floor heating pipeline grooves in the length direction.

Description

technical field [0001] The invention relates to the field of special forming combination molds for floor heating pipe grooves, and more specifically, relates to a manufacturing method of a forming combination mold for floor heating pipe grooves. Background technique [0002] 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 dry floor heating devices, which are used in dry floor heating and heating applications and overcome some of the shortcomings of the wet floor heating technology. The existing dry floor heating devices mainly include The heat insulation layer and the heat cond...
