Method for manufacturing blank of pipe clamp

Abstract

The invention discloses a method for manufacturing a blank of a pipe clamp and belongs to the field of construction. The method comprises the following steps that 1, a pipe clamp precoated sand mold is designed and manufactured according to a design drawing of the pipe clamp; 2, the precoated sand mold of the pipe clamp is placed on an automatic molding machine, and a precoated sand pouring sand shell model and a sand core model are manufactured; 3, pouring is carried out; and 4, a casting is taken out and cleaned. The method has the beneficial effects that production of the blank of the pipe clamp can be efficiently achieved, materials and manpower can be saved, and the mechanical machining amount can be reduced; and casting defects can be reduced, the yield is increased, and automatic production can be easily achieved.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a blank manufacturing method of pipe clips. Background technique [0002] The pipe clip is a pipe connection element commonly used in the construction field and the attached pipe field to replace the traditional metal pipe connection, such as figure 1 ; When the traditional metal pipeline needs to connect each section of the pipeline, it is often necessary to make flanges at both ends of the pipeline, install a gasket between the two flanges, and use bolts to lock the two flanges. The connection of two pipes has been completed. This connection is firm and reliable, but it is troublesome to install and disassemble; Convex edge, after the two convex edges are aligned, clamp the pipe clip on the convex edge of the pipe end, lock the pipe clip, and realize the connection of the two pipes, which is fast and convenient, so the connection method of the pipe clip is 100-300 in di...

[0002] The pipe clip is a pipe connection element commonly used in the construction field and the attached pipe field to replace the traditional metal pipe connection, such as figure 1 ; When it is necessary to connect each section of the traditional metal pipeline, it is often necessary to make flanges at both ends of the pipeline, install a gasket between the two flanges, and use bolts to lock the two flanges. The connection of two pipes has been completed. This connection is firm and reliable, but it is troublesome to install and disassemble; Convex edge, after the two convex edges are aligned, clamp the pipe clip on the convex edge of the end of the pipe, lock the pipe clip, and realize the connection of the two pipes, which is fast and convenient, so the connection method of the pipe clip is 100-300 in diameter The common method of connecting metal pipes with millimeter diameter, especially for temporary pipes, frequently disassembled pipes such as concrete pump pipes, fire pipes, etc.; due to the irregular shape of the pipe clamps, there are certain requirements for size and strength. Most of the blanks of the existing tube clamps are processed by lost wax casting or sand casting. These methods are costly, long process, time-consuming and labor-intensive, and the blanks of the tube clamps produced have a large machining allowance, which wastes materials and processing costs.
