The specific embodiment
Below be preferred embodiment of the present invention, but therefore do not limit protection scope of the present invention.
In conjunction with Fig. 1～shown in Figure 12, a kind of equipment that is used to produce screw rotor, it comprises frame 1, mould seat 2, rotates pipe 3, mould 4, drive and rotate power set that pipe 3 rotates and the pulling device that is used to pull cored screw rotor 15; Mould seat 2 is fixed on the frame 1, rotates pipe 3 and circumferentially is rotatably assorted in mould seat 2, and mould 4 circumferentially is limited in and rotates in the pipe 3, and pulling device is positioned at mould 4 outlet sides.The outlet side of mould 4 is the described right side of Fig. 3 just.
Rotating pipe 3 circumferentially is rotatably assorted and is meant to rotate between pipe 3 outer ends and the mould seat 2 in mould seat 2 and is provided with rolling bearing.
Described rotation is managed and is provided with two deep groove ball bearings 5 between 3 outer ends and the mould seat 2; Radially baffle ring 2.1 is arranged between two deep groove ball bearings 5, and described radially baffle ring is fixed in the mould seat 2; Rotate on the pipe 3 and also be provided with step baffle ring 3.1 and thrust bearing 6, thrust bearing 6 outsides and mould seat 2 inboards offset, and the inboard of thrust bearing 6 offsets with the step baffle ring 3.1 that rotates on the pipe 3.The outside of each parts is the right side of parts herein, and the inboard of each parts is the left side of parts, in conjunction with shown in Figure 3.
Described rotation pipe 3 is outer also to be provided with the gear teeth 3.2 that are meshed with output gear on the power set, can more obviously find out in conjunction with Fig. 5.
Described rotation is managed 3 the inners and is with a bearing block 7, rotates between pipe 3 the inners and the bearing block 7 and is provided with a rolling bearing, and bearing block 7 is fixed on the frame 1.Exploded view in conjunction with Fig. 5 can obviously be found out and understand.
The fixed cap 2.4 of described mould seat 2 Connection Block 2.3 and outer holder 2.2 by the outer holder 2.2 that links to each other with frame 1, interior Connection Block 2.3 that 3 outer ends are managed in ccontaining rotation and in being connected is formed; The inner port diameter of described outer holder 2.2 through holes is greater than the external port diameter, and described interior Connection Block 2.3 external forms match with outer holder 2.2 shape of through holes, size, and fixed cap 2.4 removably connects with outer holder 2.2 inboards.In conjunction with Fig. 3, shown in Figure 7.Among Fig. 7, interior Connection Block 2.3 can only be gone out from the left side of outer holder 2.2.
Described power set are linked in sequence successively and are formed by first motor 10, shaft coupling 11, first decelerator 12, connecting axle 13, first gear 14, in conjunction with shown in Figure 3.Above-mentioned parts are prior art, and are more general, do not giving unnecessary details at this.Also has a shaft coupling 11 between first decelerator 12 and the connecting axle 13.
Described pulling device is made up of clamp 9, second gear, second decelerator, second motor, is linked in sequence successively, and above-mentioned parts are prior art, and are more general, is not giving unnecessary details at this.The course of work mainly is exactly the second driven by motor transfer roller, transfer roller coiling rope, and rope pulling clamp 9 are convenient to clamp 9 and are clamped cored screw rotor 15 altogether, drag cored screw rotor 15 then and move.
Described mould 4 inwalls are provided with the spirality channel 4.1 that matches with cored screw rotor 15 external screw thread shapes.Among Fig. 1 is a bit of cored screw rotor 15.
In conjunction with Figure 11 and Figure 12, be the composition structure of pulling device of the present invention, clamp 9 are spacing at dolly 16 upper surfaces, and the vehicle wheel frame of dolly 16 lower surfaces is on two guide rails of correspondence.Dolly 16 upper surface sliding fits support 17, first connector 18 and second connector 19 are arranged in the support 17, place, first connector, 18 lower middles is hinged in the support 17, one end of the hinged pull bar 20 in the upper end of first connector 18, second connector 19 is fixed on the support 17, and be positioned at the outside of first connector 17, the inner of the lower end of first connector 17 and second connector 18 offsets.Be with a lead 22 outside the pull bar 20, promptly lead 22 upper ends are provided with a pilot hole, and pull bar 20 passes pilot hole.Lead 22 vertically is fixed on the dolly 16, and the outer end cap of pull bar 20 has nut, this section pull bar 20 outer springs 21 that are with between the pilot hole of nut and lead 22.Second connector, 19 outer ends are connecting a drag-line, and guy anchor is in a rotating shaft, and rotating shaft is driven by power transmitting apparatus such as motor, decelerators.In conjunction with shown in Figure 11.
The action step of explanation pulling device, when the head of cored screw rotor 15 after mould 4 comes out, this moment, pulling device prepared to clamp cored screw rotor 15 heads, turn the nut on the pulling device pull bar 20, make spring 21 be in compressive state, because the reset response of spring 21, in conjunction with Figure 12 and shown in Figure 11, the left end of spring 21 is spacing nut, the right-hand member of spring 21 is against the pilot hole place of lead 22, therefore spring 21 the elastic force effect next time pushing drawing rod 20 move, that is to say that pull bar 20 can spur the upper end of first connector 18, because place, the lower middle of first connector 18 is hinged on the support 17, therefore according to lever principle, the lower end of first connector 18 can be swung, just to the swing of the right side of Figure 12, because the lower end of first connector 18 and the inner of second connector 19 offset, therefore the lower end of first connector 18 will promote right-hand the moving of second connector, 19 past Figure 12, because second connector 19 is fixedlyed connected with support 17, support 17 is fixedlyed connected with clamp 9, therefore second connector 19 can drive clamp 9 motions simultaneously, and the jaw closure of clamp 9 is just clamped the head of cored screw rotor 15.Afterwards, the power set motor rotates, through decelerator, driving-chain, rotating shaft drag-line is forwarded in the rotating shaft, drag-line is connecting second connector 19, therefore spur support 17 last pulling clamp 9, because clamp 9 are fixed on the dolly 16, so dolly is also and then walked pulling cored screw rotor 15 on the guide rail of oneself.
Operation principle of the present invention is that the present invention adopts hollow pipe to produce the described cored screw rotor 15 of Fig. 1, existing concrete in conjunction with the accompanying drawings explanation workflow of the present invention.At first cored screw rotor 15 1 ends are struck more carefully, this end is passed mould 4, clamp 9 on the pulling device will be clamped cored screw rotor 15, draw the right side motion of cored screw rotor 15 in Fig. 3 then, and the outer surface of cored screw rotor 15 will form certain lines naturally.First motor 10 on the power set rotates, first motor 10 shaft coupling 11, first decelerator 12, connecting axle 13, first gear 14 successively rotates, because first gear 14 is meshed with the gear teeth 3.2 that rotation is managed on 3, so rotating pipe 3 rotates under the drive of first gear 14, because mould 4 and rotation are used to manage 3 axial limitings, therefore rotate pipe 3 drive moulds 4 and rotate; Because mould 4 rotates when work, only move during the work of cored screw rotor 15 and do not rotate, so cored screw rotor 15 surfaces will form certain spirality channel.As depicted in figs. 1 and 2.
When the present invention worked, mould 4 rotated, and cored screw rotor 15 passes mould 4 translations, both combinations, and therefore the outer surface at cored screw rotor 15 has formed spirality channel.
