Description
Technical field
The utility model relates to PVC pipe production equipment field, the heating device of specifically a kind of PVC pipe pipe-expanding machine.
Background technology
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 mode of heating of pipe-expanding machine is typically will
Tubing head is stretched into inside the heater box of pipe-expanding machine, and the rolling mechanism of pipe-expanding machine drives tubing rotation, and tubing head is made uniformly to add
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, make tubing head heating it is uneven, influence heating effect, cause to be flared crooked or even broken
It splits, seriously affects flaring qualification rate.
Invention content
It is good that the technical problem to be solved by the utility model is to provide a kind of heating effects, the high pvc pipe of flaring qualification rate
Material pipe-expanding machine heating device.
To solve the above problems, a kind of PVC pipe pipe-expanding machine described in the utility model adds
Thermal, including heater box, it is characterised in that：On the inside of the heater box end corresponding position be along the circumferential direction vertically installed with to
Few four equally distributed U-shaped heating tubes, and heater box end outer side center position is fixedly connected with axis；Axis front end axial plane
Upper that threading hole is equipped at the heater box position, by axle sleeve connection enlarging machine rack, end is connected with absolutely in centre position
Edge axis；The 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-core construction.
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
Type heating tube connects.
The brush connects external power supply by conducting wire.
Compared with prior art, the utility model has the following advantages：
Due to being fixedly connected with heater box in shaft head, heating chamber interior wall is provided with U-shaped heating tube, passes through the utility model
Decelerating motor drive shaft turns, make heater box along axis rotation, and heating process is become heater box rotation from tubing rotation, is avoided
It causes to heat non-uniform phenomenon because the factors such as tubing straightness itself influence tubing rotation, improves heating effect, improve
Flaring qualification rate.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the heater box side view of the utility model.
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 tubes, 11. pipe-expanding machine racks.
Specific implementation mode
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, 2 end of heater box inside corresponding position is along the circumferential direction vertically installed at least four uniformly
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, centre 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 startup deceleration after the temperature needed
Motor 8, decelerating motor 8 drive heater box 2 to rotate, and tubing head to be flared, which is put into heater box 2, heats.
