The specific embodiment
As shown in figure 13, the inside and outside thermal rotational molding technique of metallic conduit of the present invention divide the inner surface heat rotational molding technique and inside and outside mould two technologies of thermal rotational molding technique, its metal pipe internal wall thermal rotational molding technique flow process is:
Its metallic conduit inside and outside wall hot-fluid is moulded technological process and is:
Before metal tube enters this streamline, earlier the pipe fitting that processes is eliminated rust.Verifying bench 1 before the rotational moulding shown in Figure 1 is made up of rectangle table top 1-1 and supporting leg 1-2, and its table top upper end is highly contour with the high-end upper surface of Fig. 3 middle guide 2-2.Pipe fitting is after the assay was approved shifted onto and is led on the 2-2, and the guide rail 2-2 of inclination 8 is installed on the base plate of heating furnace 2, and pipe fitting can roll into heating furnace automatically, and one near a full whole heating furnace inner chamber of row.
Fig. 2, heating furnace 2 shown in Figure 3, the side door 2-7 plate of its rectangle body of heater 2-1 both sides can be opened around hinge 2-6, rolls out so that pipe fitting rolls into.Body of heater 2-1 inner chamber is uniform some electric boiling plate 2-4 and show temperature in the stove with thermometer up and down, just close the electric heater power supply when temperature reaches technique initialization numerical value automatically, realize the automation heating.Guide rail 2-2 low side in the heating furnace directly is elongated to next equipment inner surface heat rotational moulding machine.
Fig. 4, Fig. 5, hot rotational moulding machine 3 its cabinet 3-1 of inner wall of metal tube shown in Figure 6 are rectangular box, and the front and back side door 3-10 of guide rail 2-2 and guide rail 3-2 in-out end can open by hinge 3-3, and purpose is that pipe fitting rolls into and rolls out casing.Pipe fitting is supported by two active roll 3-6 and two backing roll 3.5-1 after guide rail 2-2 enters casing, active roll 3-6 drives the pipe fitting rotation under the drive of motor 3-11, open the feeding door 3-8 at cabinet 3-1 two ends, plastic pellet is sent into the pipe fitting endoporus from batching hole 3-9 equably, just can enter the inner surface heat rotational moulding.Only need operating grip 3.5-7 during the pipe fitting discharging, two backing roll 3.5-1 descend, and pipe fitting just can be led 3-12 from discharging automatically and be rolled out on the rotary table 4.Discharging track 3-12 is by two high-end being installed on the cabinet 3-1 of track support 3-14, and low side is installed on the supporting leg 3-15.
As shown in Figure 6, backing roll 3.5-1 is connected with leading screw 3.54 upper ends by axle 3.5-2 running roller bolster 3.5-3, and leading screw 3.5-4 is installed among the nut 3.5-5, and the bottom that nut 3.5-5 support 3.5-6 is installed in cabinet 3.2 is installed.
As shown in Figure 7, the pipe fitting that comes out from inwall rotational moulding machine 3, roll out through guide rail 3-12 in the groove of tiltable workbench 4-1 upper surface of rotary table 4, start motor 4-9, worm screw 4-8, rotate the rotary table rotation of drive worm gear 4-7, can incline simultaneously and expect that workbench 4-1 also together rotates together with the pipe fitting on top together with top.When pipe fitting revolve turn 90 degrees enter hot rotational moulding nature cooler 5 and carry out the nature cooling after, driving is hung the product inspection platform with pipe fitting and is tested, and finishes single inner surface heat rotational molding technique flow process.Pipe fitting Rotate 180 degree on rotary table, pipe fitting enter the hot rotational moulding machine 6 of outer wall.
Be illustrated in figure 7 as rotary table 4, the rotary table 4-6 of its tiltable workbench 4-1 and bottom is by hinge joint bearing 4-2 hinge joint, and use handwheel 4-4, and leading screw 4-3 and nut 4-5 realize the inclination of workbench, purpose is that pipe fitting can roll into automatically on workbench and rolls out.Boss on the tiltable workbench 4-1 also is for pipe fitting rolls into the security consideration that rolls out, and its Baltimore groove is the usefulness for the pipe fitting location.
Figure 8 shows that hot rotational moulding nature cooler 5, inclined guide rails 5-13 on the movable supporting frame 5-14 at its middle part is rolled into the pipe fitting that transfers on the rotary table 4 at the middle part of cooler, operation handwheel 5-1, some cramp bar 5-6 on two garden shape supporting disk 5-5 are installed to pipe fitting on the cooler, open motor 5-11 and make the cooling of pipe fitting rotation carrying out nature.
As shown in figure 12, the pipe fitting that cooling is good lifts by driving and carries out product inspection on the product inspection platform 8 naturally, and then the pipe fitting of acceptance or rejection is hung appointed positions with driving.Finish whole work of inner wall of metal tube thermoplastic.
As shown in Figure 9, it is to realize like this that metal tube inside and outside wall heat is rolled the wall flow process, rotary table 4 Rotate 180 degree, be rolled into the pipe fitting of finishing the inner surface heat rotational moulding among the casing 6-26 of the hot rotational moulding machine 6 of outer wall through the second track 6-28, starter motor 6-16 makes moving frame 6-4 motion, utilizes two cramp bar 6-10 on first, second supporting disk 6-9, the 6-13 that pipe fitting is clamped.Starter motor 6-1,6-3 drives drive roll 6-6 rotation by the band transmission, and drive roll 6-6 drives first supporting disk 6-9 rotation, also rotation thereupon of pipe fitting simultaneously.The high pressure gas of Open valve 6-25 gas tank 6-23 enters hopper 6-22 and stuff-spraying pipe 6-21, and high pressure gas blows afloat the plastics among the hopper 6-22 and is full of whole case groove 6-26, and progressively is adsorbed on the pipe fitting of heating, and realization pipe fitting outer wall heat is rolled wall.After the hot rotational moulding of outer wall is finished, open upper box lid 6-12, mobile traversing carriage 6-14 lifts pipe fitting in the hot rotational moulding insulating box 7.
Shown in Figure 11, pipe fitting after outer wall heat is rolled hangs among the casing 7-11 of hot rotational moulding insulating box 7, operation handwheel 7-1, pole 7-18 on the supporting disk 7-8 is installed pipe fitting, open motor 7-15 and make the pipe fitting rotation, electric boiling plate 6-16 heating makes pipe fitting keep certain constant temperature time in insulating box, reaches the effect of plasticizing.After finishing the constant temperature plasticizing, open loam cake 7-10, with driving pipe fitting is hung on the hot rotational moulding nature cooler 5 and carry out the nature cooling, (natural cooler front is told about) hangs 8 checks of product inspection platform, the qualified metal tube inside and outside wall thermal rotational molding technique flow process of finishing at last.
