Adjustable heat shrink tube limit heating and sizing device

Abstract

The invention discloses an adjustable heat shrink tube limit heating and sizing device, comprising a limit heating furnace and a limit sizing clamp, wherein the limit heating furnace comprises a temperature controller (1), a furnace case cover body (2), operation bars (3), hearths (4) and a furnace bottom (7). The device is characterized in that a plurality of hearth guide slots are vertically formed in the furnace bottom (7); a height adjusting support (11) is arranged on the slot shoulder between two adjacent hearth guide slots (8) and is provided with a height adjusting screw (6); hearth supports (10) are connected with the height adjusting supports (11) movably in the vertical direction and are specially connected with the height adjusting screws (6); a plurality of hearths (4) are connected with the lower parts of the hearth supports horizontally arranged and are in one-to-one correspondence with the hearth guide slots (8); the operation bars are slidably connected with the hearth guide slots (8). According to the invention, the working temperature and working height of the limit heating furnace can be adjusted based on the technical requirements of products, thus well solving the problem of poor quality stability of heat shrink tubes in a limit sizing process.

Description

technical field [0001] The invention belongs to the technical field of processing equipment for electrical conduction devices, and relates to an adjustable heat-shrinkable tube limit heating and shaping device. technical background [0002] The heat-shrinkable tube is a tubular tape-like structure, the inner wall is coated with hot-melt adhesive, the wall is thick, has good adhesion, sealing and flame retardancy, and has good waterproof performance. It is mainly used in the middle and terminal of cables and wires. Protection, widely used in automotive wires, metal pipes, connectors, insulation and wire binding. At present, the heat-shrinkable tubes are limited and shaped mainly by the single-furnace heating and shaping process (that is, using manual single, single-furnace heating and shaping). This traditional process not only has low efficiency and high labor intensity, but also produces unstable product quality. Can not adapt to mass production, multi-standard, multi-vari...

AI Technical Summary

Problems solved by technology

At present, the heat-shrinkable tubes are limited and shaped mainly by single-furnace heating and shaping process (that is, using manual single, single-furnace heating and shaping). This traditional process not only has low efficiency and high labor intensity, but also produces unstable product quality. Can not adapt to mass production, multi-standard, multi-variety production

It can be seen that the existing technology, that is, the single furnace heating and setting production efficiency is low, and cannot adapt to industrialized large-scale production
