Quantitative and adjustable extrusion tool for glue solution

Abstract

A quantitative and adjustable glue solution extrusion tool belongs to the technical field of transformers and comprises a shell, a bottom plug, a conveying part and an extrusion part, the bottom plug is mounted at the bottom of the shell, the conveying part is mounted on the bottom plug and located in the shell, and the extrusion part is mounted on the top of the shell and makes contact with the conveying part. The shell comprises a barrel, a bottom hole, a top cover and a core hole, the bottom hole is formed in the bottom of the barrel, the bottom plug is installed on the bottom hole, the top cover covers the top of the barrel, the core hole is formed in the ejector rod, and the extrusion part is installed on the core hole. The bottom plug comprises a plug body, a seat hole, a through hole and guide rods, the plug body is installed on the bottom hole, the seat hole is formed in the center of the plug body, a glue guide pipe of the conveying part is installed on the seat hole, the through hole is formed in the eccentric position of the plug body and penetrates through the whole plug body, a glue dripping pipe is installed on the through hole, and the four guide rods are evenly distributed on the circumference of the plug body and connected with the lugs of the conveying part. The conveying part comprises a sleeve, a pressing cap, a glue guide pipe, a small spring, a piston ball, a glue dripping pipe and a nut, the sleeve is of a hollow structure, and the sleeve is installed on the bottom plug through a guide rod and the small spring.

Description

technical field [0001] The invention belongs to the technical field of transformer manufacturing, and in particular relates to a quantitative and adjustable extrusion tool for glue liquid. Background technique [0002] In the production of transformers, a large number of insulating parts are required. In the manufacturing process of insulating parts, it is very common to use glue to form insulating parts that can be used on specific transformer models. When glue is used to bond and manufacture insulating parts, the amount of glue is an important control variable. Too much glue may cause glue overflow and affect the quality of parts. Too little glue may lead to weak bonding. On the production line, the amount of glue for each bonding operation is controlled by the operator's experience. Therefore, even for the same parts, it is difficult to maintain the same glue content of insulating parts bonded in different batches. SUMMARY OF THE INVENTION [0003] The present inventio...

Problems solved by technology

When using glue to bond insulating parts, the amount of glue is an important control variable. Too much glue may cause glue overflow and affect the quality of parts. Too little glue may lead to weak bonding. The current On the production line, the amount of glue used for each bonding operation is controlled by the experience of the operator. Therefore, even for the same parts, it is difficult to keep the glue content of insulating parts bonded in different batches consistent.
