Forming device for faucet pipe body and method for forming faucet pipe body through forming device

Abstract

A faucet pipe body forming device, including a hydraulic pressure generating system, a hydraulic bulging press, and an internal high-pressure forming die. The internal high-pressure forming die includes an upper die and a lower die. Die holes, including short and long end round die holes and vertically arranged manifold circular grooves, long and short end round die holes are installed with left and right push heads for tight sealing, the oil inlet channel of the right push head is connected with the high-pressure oil circuit, and the manifold is round A back pressure piston is installed in the die hole, and the left and right push heads and the back pressure piston are respectively connected with the left and right oil cylinders and the back pressure oil cylinder of the hydraulic bulging press. The method for manufacturing the faucet body includes the steps of: S1 using the internal high pressure forming technology to manufacture the semi-finished faucet body, S2. using the conventional bending process to form the finished faucet body. The design of the device is scientific, and the method of using the forming device to manufacture the complex-shaped faucet body fully utilizes the advantages of the internal high-pressure forming technology and the conventional pipe bending process, which can make the manifold end precisely formed, and the quality of the formed pipe body is good.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a pipe material processing device and method, in particular to a faucet pipe body forming device and a method for forming a faucet pipe body by using the same. Background technique [0002] The faucet is one of the bathroom hardware products. Its characteristics are dense organization and compact structure, and asymmetry. It is generally a three-way pipe with a curved end. The straight end is the main water pipe connection port, the curved end is the water outlet, and the waist is the switch. Installation port (manifold port); due to the above characteristics, it brings a lot of trouble to the production (difficult to form). [0003] The traditional faucet (product blank) mainly adopts the casting process. Firstly, the mold and process are designed according to the product drawing, then the mold is processed and manufactured, and finally the mold is tested and the equ...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the dense structure and compact structure of the faucet, it is required that the casting structure, pouring system and process parameters be set very reasonably, otherwise various casting defects will occur in actual production, which will affect the quality of the formed product (two-thirds of the defects in the faucet product manufacturing process are produced by the first process "casting");

[0005] 2. In the casting process, the filling time of the casting is long, the heat transfer speed of the metal mold is fast, and a large amount of energy is lost during the filling process, resulting in high energy consumption;

[0006] 3. Due to the difficulty in forming the faucet, the traditional manufacturing process involves many factors affecting the forming, and there may be mutual coupling between the multiple factors, so it is often necessary to go through multiple test molds and continuously adjust the equipment parameters to verify the rationality of the casting process. If the qualified rate of the trial production is too low, it is necessary to modify the process plan and the mold, and then proceed to the next trial until the qualified rate of the product is guaranteed. Not only the construction period is long, but also the cost is high
