Description

U-shaped water pipe manufacturing device and manufacturing method Technical Field The invention relates to the technical field of bent pipe forming, in particular to a U-shaped water pipe manufacturing device and a manufacturing method. Background The TEC type water chiller, i.e. a thermoelectric cooler (Thermoelectric Cooler) water chiller, is a refrigerator made of semiconductor materials. The U-shaped water pipe in the TEC type water chiller is generally made of plastic pipes, such as PFA pipes. One way to make the U-shaped water pipe in TEC type water chiller is as follows, a proper spring is introduced into the plastic pipe, then the plastic pipe is heated by a hot air gun, bent by hand, and cooled to obtain the U-shaped water pipe. The existing manufacturing mode of the U-shaped water pipe has the defects that the requirement on an operator is very high, the U-shaped water pipe is manually bent, the accuracy and consistency of the shape and the size of the U-shaped water pipe are difficult to ensure, and the product percent of pass is poor. In addition, the U-shaped pipe is easy to rebound and deform. For example, the invention of Chinese patent publication No. CN102049854A, the name of which is plastic profile bending technology, comprises the following steps, namely, a plastic pipe molding or selecting molded plastic pipe, b heating the pre-bending position of the plastic pipe to soften the plastic pipe, c bending and shaping the plastic pipe. Disclosure of Invention The invention aims to provide a U-shaped water pipe manufacturing device and a U-shaped water pipe manufacturing method capable of conveniently and rapidly manufacturing a U-shaped water pipe and effectively improving the manufacturing efficiency and the qualification rate of the U-shaped water pipe. The technical scheme of the invention is as follows: The utility model provides a U type water pipe manufacturing installation, includes base and water pipe preparation subassembly, and the water pipe preparation subassembly includes: The spiral spring is inserted into the water pipe; the device comprises a fixed forming part, a pressing block and a pressing block driving mechanism, wherein the fixed forming part is fixed on a base, and the pressing block driving mechanism drives the pressing block to be close to or far away from the fixed forming part; The forming piece is positioned between the two limiting through holes, and the limiting through holes are positioned at the edge of the forming piece. The specific application of the U-shaped water pipe manufacturing device of the scheme is as follows, Inserting a coil spring into the water pipe, wherein two ends of the coil spring extend out of the water pipe; Manually bending the water pipe, inserting two ends of the water pipe into two limiting through holes of the same water pipe manufacturing assembly, and enabling the water pipe to be tightly abutted against the outer peripheral surface of the forming block; the pressing block driving mechanism drives the pressing block to be close to the fixed forming piece and prop against the water pipe, so that the water pipe is kept close to the periphery of the forming block. Then, the bending portion of the water pipe is heated, for example, by a heat gun, and then cooled and shaped. For example by spraying cooling water over the bent portion of the water pipe. The U-shaped water pipe is shaped by utilizing the cooperation of the fixed forming piece and the pressing block, the accuracy and the consistency of the shape and the size of the U-shaped water pipe are ensured, the rebound deformation of the U-shaped pipe is effectively avoided, the manufacturing efficiency and the qualification rate of the U-shaped water pipe are effectively improved, and the U-shaped water pipe can be conveniently and rapidly manufactured. On the other hand, because the water pipe is internally inserted and provided with the spiral spring, the inner wall of the water pipe can be supported by the spiral spring in the cooling process after the bending part of the water pipe is heated, so that the shrinkage deformation of the water pipe in the cooling process is effectively reduced, the accuracy and consistency of the shape and the size of the U-shaped water pipe are further ensured, and the manufacturing qualification rate of the U-shaped water pipe is improved. Preferably, the pressing block is provided with an arc surface which is concave towards the side surface of the fixed forming part, and the arc surface is provided with an arc pressing groove which penetrates through two sides of the pressing block. Thus, in the manufacturing process of the U-shaped water pipe, when the pressing block driving mechanism drives the pressing block to be close to the fixed forming part and to be propped against the water pipe, the bending part of the water pipe is limited in the arc-shaped pressing groove, the position and the shape of the water pipe are limited through the arc-sha
