Description
Technical field
The present invention relates to PVC pipe production equipment field, the heating device of specifically a kind of PVC pipe pipe-expanding machine.
Background technique
Flaring processing usually is carried out to tubing one end using pipe-expanding machine in PVC pipe production process, to facilitate tubing
Connection.Tubing head is heated to softening by pipe-expanding machine when carrying out flaring operation, currently, the heating method of pipe-expanding machine is usually will
Tubing head is protruded into inside the heater box of pipe-expanding machine, and the rolling mechanism of pipe-expanding machine drives tubing rotation, adds tubing head uniformly
Heat extremely softens.But in the actual production process, due to the influence of tubing straightness, the poor tubing of straightness is in pipe-expanding machine
Rolling mechanism on be difficult to uniform rotation, keep the heating of tubing head uneven, influence heating effect, lead to flaring skew or even broken
It splits, seriously affects flaring qualification rate.
Summary of the invention
It is good that technical problem to be solved by the invention is to provide a kind of heating effects, and the high PVC pipe of flaring qualification rate expands
Mouth machine heating device.
To solve the above problems, a kind of heating device of PVC pipe pipe-expanding machine of the present invention, packet
Include heater box, it is characterised in that: corresponding position is along the circumferential direction vertically installed at least four on the inside of the heater box end
The U-shaped heating tube of even distribution, and heater box end outer side center position is fixedly connected with axis；Close to institute on the axial plane of the axis front end
It states and is equipped with threading hole at heater box position, by axle sleeve connection enlarging machine rack, end is connected with shaft insulation in middle position；It is described
Insulation shaft end is socketed with two copper rings, which is provided with brush.
The heater box is cylindric, and front end is open design.
The axis connects decelerating motor by chain.
The axis and the shaft insulation are hollow structure.
The shaft insulation is internal, the conducting wire of internal, the described threading hole of the axis and the U by sequentially passing through for the copper ring
The connection of type heating tube.
The brush connects external power supply by conducting wire.
Compared with prior art, the invention has the following advantages that
Due to being fixedly connected with heater box in shaft head, heating chamber interior wall is provided with U-shaped heating tube, passes through decelerating motor the present invention
Drive shaft turns, make heater box along axis rotation, and heating process is become heater box rotation from tubing rotation, is avoided because of tubing sheet
The factors such as body straightness influence tubing rotation and cause to heat non-uniform phenomenon, improve heating effect, improve flaring and close
Lattice rate.
Detailed description of the invention
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is heater box side view of the invention.
In figure: 1. axis, 2. heater boxes, 3. shaft insulations, 4. copper rings, 5. brushes, 6. axle sleeves, 7. threading holes, 8. deceleration electricity
Machine, 9. chains, 10.U type heating tube, 11. pipe-expanding machine racks.
Specific embodiment
With reference to the accompanying drawings shown in 1,2, a kind of heating device of PVC pipe pipe-expanding machine, including heater box 2, the heater box 2 are circle
Column, and front end is open design, corresponding position is along the circumferential direction vertically installed at least four uniformly on the inside of 2 end of heater box
The U-shaped heating tube 10 of distribution, and 2 end outer side center position of heater box is fixedly connected with axis 1, which is subtracted by the connection of chain 9
Speed motor 8；Threading hole 7 is equipped on 1 front end axial plane of axis at 2 position of heater box, middle position passes through 6 connection enlarging machine of axle sleeve
Rack 11, end are connected with shaft insulation 3；For the socket of 3 end of shaft insulation there are two copper ring 4, which is provided with brush
5, which connects external power supply by conducting wire, copper ring 4 by sequentially passing through inside shaft insulation 3, inside axis 1, threading hole 7
Conducting wire is connect with U-shaped heating tube 10.
In use, connecting 5 power supply of brush, U-shaped heating tube 10 is begun to warm up, to be heated to starting deceleration after the temperature needed
Motor 8, decelerating motor 8 drive heater box 2 to rotate, and tubing head to be flared is put into the heating of heater box 2.
