FRP tank body flexible grinding device

Abstract

The invention relates to an FRP tank body flexible grinding device. The flexible grinding device comprises a machine frame, two air cylinders horizontally arranged on the machine frame, a support, a pneumatic grinding machine which is arranged on the support and is back onto one sides of the air cylinders, a sliding rail which is vertically arranged on the support and faces one sides of the air cylinders, and a sliding block which cooperates with the sliding rail, a push rod of the air cylinder located on the upper layer is hinged to the support, a push rod of the air cylinder located on the lower layer is hinged to the sliding block, the working face of the pneumatic grinding machine is abrasive paper, and a sponge layer is arranged on the inner side of the abrasive paper. The FRP tank body flexible grinding device is small in weight, simple in structure, low in cost and capable of finishing grinding of cambered surface, deformation and local concave-convex parts.

Description

technical field [0001] The invention belongs to the field of processing FRP tank bodies, and in particular relates to a flexible grinding device for FRP tank bodies. Background technique [0002] FPR is Fiber Reinforced Plastics, also known as FRP, which is a fiber-reinforced composite material that uses glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as a reinforcing material and synthetic resin as a matrix material. Due to its light weight, high strength and strong corrosion resistance, FPR is widely used in the water treatment industry and is usually used to produce water treatment tanks. [0003] The FRP tank body includes an inner tank and a reinforcement layer. The manufacturing process of the inner tank mainly includes: coating the release material on the surface of the mold, and then coating the glass fiber and the prepared glue into the mold, and then curing (usually at room temperature) or heated environment) after demoulding. However, due to t...

Problems solved by technology

However, due to the adhesiveness of the release material, the release wax will remain on the outer surface of the liner after demoulding, which will affect the effect of fiber winding. After the surface is treated, the residual release wax is removed, and then it is bonded with the processed inner lining parts such as the head to form a whole container, and the winding reinforcement layer is processed

[0004] In the past, when the FRP tank body was polished, manual polishing was used. Not only the harsh working environment would be harmful to the workers' health, but also the quality of the polishing was difficult to guarantee.

At present, automatic grinding equipment is also used in the process of grinding FRP tanks. Since the control of the contact force between the grinding head and the surface of the tank needs to be considered, the automatic grinding equipment includes sensors, flexible flanges and control systems. Therefore, the cost Higher, unaffordable for small businesses
