Problems solved by technology

Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Castings produced by sand casting need to clean the inner and outer cavities after demoulding. At present, most of them use manual cleaning. The specific method is: remove the slag with a hammer Gate and shake off the sand of the casting, and then use a sandblasting machine for sandblasting; the slag removal efficiency of this method mainly depends on the proficiency of the workers, the slag removal efficiency is low, and the work intensity of the workers is relatively high

Embodiment Construction

[0036] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0037] Such as Figure 1 to Figure 9 As shown, a post-processing process for casting and demoulding of metal pipe fittings is mainly completed by a post-processing device for casting and demoulding of metal pipe tee joints. Including the installation frame 10 and the tee connector 30, the post-processing process of the metal pipe fitting after casting and demoulding specifically includes the following steps:

[0038] S1. Fixing of pipe fittings: first manually fix the tee connectors 30 to be cleaned of slag evenly in the metal pipe tee connectors in the post-processing device for casting molding and demoulding;

[0039] S2. Horizontal slag removal treatment: the tee connector 30 fixed in step S1 is casted and molded by the metal pipe tee connector ...

Abstract

The invention relates to a post-processing technology for casting and demoulding of metal pipe fittings. Including the installation frame and the three-way connector, the installation frame is composed of a vertical plate and a horizontal plate set at the bottom of the vertical plate, and there are multiple sets of clamping mechanisms on the front of the vertical plate, and the three-way connector is fixed in the clamping mechanism , the top of the vertical plate is provided with a horizontal slag removal mechanism, and the top of the horizontal plate is provided with a longitudinal slag removal mechanism. The invention utilizes multiple sets of clamping mechanisms to fix the three-way connectors, so that the horizontal slag removal mechanism and the vertical slag removal mechanism can simultaneously perform slag removal on the inner cavities of multiple three-way connectors, which improves the slag removal efficiency and reduces the labor force of workers. Work intensity.

Description

technical field [0001] The invention relates to the technical field of casting treatment of metal pipe fittings, in particular to a post-treatment process for metal pipe fittings after casting and demolding. Background technique [0002] Tees, also known as pipe fittings tees or tee fittings, tee joints, etc., are mainly used to change the direction of the fluid. They are used at the branch pipes of the main pipeline and can be classified according to the size of the pipe diameter. It is generally made of carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, PVC and other materials, and the tee connector of the metal pipe fitting is formed by casting. [0003] Sand casting refers to the casting method that produces castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Castings produced by sand casting need to clean the inner and outer cavities after demoulding. At present, most of t...
