The set of equipment can perform point heating instead of integral heating according to the required three-dimensional shape of the plastic pipe, so as to realize the energy saving purpose; finally, the required fuel pipe is molded on the forming mould, and the plastic fuel pipe molding equipment has the advantages that the whole investment is economical, the energy consumption is low, and the operation is convenient.

Description

Plastics fuel pipe former

One, technical field

The utility model relates to a kind of manufacturing equipment of auto parts machinery, particularly relates to a kind of automotive plastic fuel pipe former.

Two, background technology

At present the fuel pipe that uses on the automobile replaces metal by plastics mostly, and the advantage of plastics fuel pipe is, and is in light weight, price is low, is difficult for infiltration, painted convenience, and easier location, inspection and installation.But since fuel pipe be shaped as the irregular abnormity of three dimensions, its moulding process is special, the techniques of mass production difficulty is higher.Mainly contain two kinds of processes at present, the one, utilize large-scale drying room, earlier with plastic tube forced shaping under cold conditions, be put into heating in the drying room then, make pipe hot softening down, shift out cooling and shaping behind the drying room.This method can realize high efficiency, but invests higherly, and energy consumption is also bigger.The 2nd, utilize baking oven with the preheating of plastic tube elder generation, place then on the make-up machine to be shaped and cooling and shaping.The advantage of this method is to invest not highly, but production efficiency is low, and power consumption is also bigger.The common ground of above-mentioned two kinds of processes is that the deformation point of actual plastic tube is mainly at crooked position to the whole heating of plastic tube, and in fact the heating of other non-deformation places has wasted heat energy.

Three, utility model content

The purpose of this utility model is to provide a kind of energy to satisfy the plastics fuel pipe former of producing needs in batches, and its maximum characteristics are only to the deformation place heating, to reach the purpose that cuts down the consumption of energy and be convenient to operate.

For realizing above purpose, the technical solution of the utility model is: the utility model plastics fuel pipe former, it is made up of several heaters and molding fetal, wherein, described heater is made up of heater, cylinder and temperature controller, heater is located on the workbench, be to constitute by two electric heating materials, medial surface is semi-circular, can be to the heating of round plastic pipe, the one piece is fixed on the workbench, and another piece can drive translation by cylinder, to unclamp or to clamp plastic tube, the time and the temperature of its heating are set in advance by temperature controller.Described heater according to the plastic tube 3D shape of required moulding, can be designed to many groups, heats with the position that need be out of shape plastic tube, and these heaters should be in same level and same straight line, and are installed on the workbench.This workbench should be complementary with the total length of the plastic tube of required moulding.On the heater next door, a sleeving plastic pipe molding fetal is installed, be used for thermoplastic plastic tube is forced moulding and fixing, then inside of plastic tubes is passed to running water or other cooling mediums, make the plastic tube typing, become the fuel pipe of required form.

Add man-hour, to place the centre of heater by the stretched plastic straighttube of extruder earlier, start the compressed air flow divider, open cylinder and move switch, connecting compressed air moves cylinder simultaneously, the heater translation is closed up, power-on control cabinet then, make heater connect power supply, to each position local heat of plastic tube, the heating-up temperature value at each position of plastic tube is by the material property of plastic tube and shape decision thereof and be preset in advance in the temperature controller, treat that each position heating-up temperature reaches setting value after, each temperature controller is cut off the electricity supply automatically, and heater stops heating.Simultaneously, cylinder moves switch motion, makes each cylinder drive heater translation separation separately, takes out plastic tube and places the plastic tube molding fetal, is fixed, and makes plastic tube form the shape consistent with mold.At last plastic tube is passed to running water (or other cooling mediums), make the whole cooling of plastic tube, be permanently deformed to required shape,, can utilize gases at high pressure that the residue in the pipe is blown away for preventing residual cooling medium in the pipe.

The beneficial effects of the utility model are:

1, extruder is stretched plastic tube carries out branch heating rather than whole heating by desired three dimensional shape, reaches the purpose of saving the energy, is shaped to required fuel pipe at last on mold.Overall investment economizes, and energy consumption is low, easy to operate.

2, to same shape, diameter and the little fuel pipe of overall length difference distance, can on same device, carry out.

3,, only need change the plastic shaping mold and adjust heater position and group number for difform fuel pipe.

Four, description of drawings

The structural representation vertical view of Fig. 1, the utility model plastics fuel pipe former.

Five, the specific embodiment

Below in conjunction with drawings and Examples plastics fuel pipe former of the present utility model is described further:

As shown in Figure 1, the utility model plastics fuel pipe former, its composition comprises: heater, described heater is made up of

heater
