A safety bending mechanism for pvc pipe installation

Abstract

The invention discloses a safe bending mechanism used in the installation process of PVC pipes in the technical field of PVC pipe processing. It includes a support base plate, a support side plate is vertically welded on the left side of the top of the support base plate, and the front and rear side walls of the support base plate are welded. There are two sets of limit support plates, and the limit support plates are set on the right side of the support side plate. The middle part of the right side wall of the support side plate is fixed with a nozzle fixing device by bolts. The top of the limit support plate is longitudinally provided with a limit slide Groove, the present invention can bend PVC pipes with different pipe diameters, and can adjust the distance between the heating fan and the PVC pipe according to the pressure of the pipe diameter on the supporting arc plate. The closer the distance between the PVC pipes, the higher the heating temperature of the PVC pipes, so that the large-diameter PVC pipes can be heated quickly, and the PVC pipes can be bent quickly, saving time and effort, and the bending angle is consistent. Ensure that the PVC pipe is fully used.

Description

technical field [0001] The invention relates to the technical field of PVC pipe processing, in particular to a safety bending mechanism used in the installation process of PVC pipes. Background technique [0002] PVC pipe Rigid polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc., and then extruded by hot pressing. It is the earliest plastic pipe that has been developed and applied. PVC-U pipe has strong corrosion resistance, easy bonding, low price, and hard texture. However, due to the leakage of PVC-U monomer and additives, it is only suitable for water supply systems with a delivery temperature not exceeding 45°C. Plastic piping is used in applications for drainage, waste water, chemicals, heating and cooling fluids, food, ultrapure liquids, slurries, gases, compressed air and vacuum systems. [0003] PVC can be divided into soft PVC and hard PVC. Among them, soft PVC is generally used for floors, ceilings and leather surfaces, but b...

Problems solved by technology

[0004] At present, PVC pipes and pipe joints are installed with hot-melt technology to install the pipe layout. There will be safety hazards through too many joints. When using PVC pipes, they can be bent directly according to the situation. If the pipes are bent, no elbows are needed. , one less joint will reduce one hidden danger. It takes a lot of manpower to directly bend the PVC pipe angle manually, the bending angle is different, and it is easy to cause the damage of the pipe fittings due to the uneven strength of manual bending Based on this, the present invention designs a safety bending mechanism used in the installation process of PVC pipes to solve the above problems
