Problems solved by technology

This method of immersing the heat-shrinkable tube in the hot liquid with the perforated iron oil bath tube can solve the technical problem of uneven heating caused by the heat-shrinkable tube floating on the liquid surface, but there is a problem that the heat-shrinkable tube is in the iron oil bath. The inside of the tube is heated and becomes soft, and there is no traction force during the axial movement

Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] see figure 1 , the present invention provides a clamp mechanism 2, comprising several U-shaped clamps 201, a connection mechanism 202 connecting the clamps 201, and a transmission mechanism 203 for driving the connection mechanism 202, and in the clamp mechanism 2, several clamps 201 are arranged in parallel It is divided into upper and lower layers, the U-shaped opening of the upper layer is upward, and the U-shaped opening of the lower layer is downward. Each clamp 201 moves reciprocatingly under the action of the connecting mechanism 202 .

[0025] see figure 1 , in an embodiment of the clamp mechanism 2 of the present invention, horizontal steel bars are welded on the outer sides of each clamp 201. After the L-shaped steel bars in the connecting mechanism 202 are threaded, each clamp 201 is connected in parallel, and the connectio...

Abstract

The invention discloses a clamping mechanism and a heat shrink tubing positive companding device using the same. Compared with the spraying mode, the provided device can heat a heat shrink tubing more evenly, the thermal efficiency is higher, the required liquid temperature can be reduced by roughly 20 to 40 DEG C, the energy consumption is reduced, more importantly, the heat shrink tubing is completely soaked in the oil and is synchronously pulled out with the clamp, the wall of the heat shrink tubing is uniform, and no beveled edge is generated in the cross section. In the conventional method, a heat shrink tubing is soaked in hot liquid in an iron oil-bath tube with an opening, while in the provided method, the clamping mechanism can pull the heat shrink tubing to move in the liquid, and thus the heated and soft heat shrink tubing will not be pulled upwards.

Description

technical field [0001] The invention relates to heat-shrinkable tube processing equipment, in particular to a clamp mechanism and a heat-shrinkable tube positive pressure expansion device using the clamp mechanism. Background technique [0002] Heat-shrinkable tubes are widely used, and they are very important in the connection wires, wires, cables, etc. of electronic equipment that people come into contact with in daily life. [0003] Before the heat-shrinkable tube is applied to the end product, it needs to be heated to expand the diameter of the tube so that the tube wall can be changed from thick to thin. The traditional heating expansion is to spray the heat-shrinkable tube with a liquid at 150~180°C in a closed box, such as glycerin, ethylene glycol, etc. When this kind of heating expansion is in progress, the heat-shrinkable tube floats on the surface of the liquid to receive the spray. [0004] The traditional positive pressure expansion of heat-shrinkable tubes has...
