Embodiment
1-4 makes a detailed explanation the specific embodiment of the present invention below in conjunction with accompanying drawing.
A kind of metal axial-flow fan roller riveting and forming machine shown in Fig. 1-4 is by frame 1 and be installed in roll riveting axle rotating mechanism, roll riveting mechanism 3 and retention mechanism 4 on the frame 1.
Roll riveting axle rotating mechanism is made of motor 2 and roll riveting axle 15, and motor 2 is installed on the position of frame 1 bottom, and roll riveting axle 15 1 ends are fixed on motor 2 output terminals and can rotate with it, and roll riveting axle 15 is installed in the top of frame 1 end face.
Roll riveting mechanism 3 is vertically set on the hob head 17 that 8,2 of screw mandrels and roll riveting axle 15 on frame 1 end face be arranged in parallel by feed control device, with roll riveting axle 15 and is fixed on many on the hob head 17 hobboing cutter 19 is constituted.Screw mandrel 8 is fixed on frame 1 end face by 2 bearing supports 16 up and down.2 hob heads 17 mesh at two ends about in the of 8 with screw mandrel respectively, and the screw thread at screw mandrel two ends about in the of 8 is opposite, and 2 hob heads 17 of screw mandrel 8 positive and negative rotations are done rightabout motion thereon.Feed control device comprises hydraulic pressure installation 11, oil cylinder 6 and the cylindricality tooth bar 7 that links to each other successively.Cylindricality tooth bar 7 links to each other by gear with screw mandrel 8 upper ends, and the clockwise and anticlockwise control screw mandrel 8 by cylindricality tooth bar 7 rotates, and promptly controls moving up and down of the hob head 17 of doing the opposite direction motion on the screw mandrel 8.Be respectively equipped with guide rail 18 on 2 hob heads 17, hobboing cutter 19 dismountable being installed on the guide rail 18, the hobboing cutter 19 on every group of hob head 17 is respectively 6, and two groups amount to 12 up and down, and two group 12 is hobboing cutter 19 center symmetric arrays setting with roll riveting axle 15 up and down.During the different metal axial-flow fan of joint length, a position that only needs to adjust hobboing cutter 19 on the guide rail 18 gets final product in the processing
Hobboing cutter 19 is made of regulating handle 21, dial 22, tool-post structure 23, adjusting screw mandrel 24, tool tip 25 and cutter head 26.Tool tip 25 is installed in the fore-end of tool-post structure 23, cutter head 26 is installed on the tool tip 25, regulate screw mandrel 24 and run through dial 22 its front ends and stretch in the tool-post structure 23 and with tool tip 25 and link to each other, regulating handle 21 is arranged on the tail end of regulating screw mandrel 24 and rotatable adjusting screw mandrel 24.Regulating handle 21 is by rotating the distance of regulating screw mandrel 24 control tool tip 25 and going up cutter head 26 advance and retreat.The level height of cutter head 26 is highly corresponding with roll riveting axle 15, and the cutter head 26 on all hob heads 17 all is on the same horizontal line and is parallel with roll riveting axle 15.Can regulate and show the distance of regulating by regulating handle 21 when deviation appears in the distance when hobboing cutter 19 deviation occurs separately between cutter head 26 and the roll riveting axle 15, be convenient to write down adjusting with other hobboing cutter 19 by dial 22.Described cutter head 26 is made of pedestal 29 and last two blades that be arranged in parallel 27 thereof, form guiding groove 28 between two parallel blades 27, promptly the distance between two parallel blades 27 is exactly the width of guiding groove 28, and the thickness of the width of guiding groove 28 and impeller mid-game coupling, add man-hour, mid-game is as in the guiding groove 28, the middle disc thickness that processes is identical, the distance that the mid-game of processing different-thickness can be adjusted between two parallel blades 27 realizes, solved that hobboing cutter can not guarantee all identical thickness problem not of uniform size that causes roll riveting moulding mid-game circumference outer end at every turn with mid-game periphery surface of contact in the existing equipment.
Retention mechanism 4 is by cylinder assembly, hold-down head 13, roll sleeve 5 be enclosed within on the left end and can constitute along the compressing member 20 of roll riveting axle 15 move left and right.Cylinder assembly is made of the Pneumatic actuator 12, tailstock cylinder 9 and the roof pressure cylinder 10 that link to each other successively, and hold-down head 13 is installed on the output terminal of roof pressure cylinder 10, and roll sleeve 5 is installed in and is used to hold out against roll riveting axle 15 the other ends on the roof pressure cylinder 10.Hold-down head 13 and compressing member 20 positions are corresponding with roll riveting axle 15, but compressing member 20 is set in the left end and the move left and right of roll riveting axle 15, hold-down head 13 is fixed on the output terminal of roof pressure cylinder 10, and compressing member 20 is used with hold-down head 13 and is used for fixing the position of metal axial-flow fan on roll riveting axle 15.When the short metal axial-flow fan of processing length, all to be put into the left end of roll riveting axle 15 to fan so that fixing of fan left end at every turn, because distance length comes back operations relatively to lose time, compressing member 20 is set freely adjusts distance to be processed and lock then just not need all fan to be put to roll riveting axle 15 left ends at every turn and bother so, improved work efficiency.
Using process is as follows:
The metal axial-flow fan that assembles is enclosed within on the roll riveting axle 15.Tailstock cylinder 9 action earlier pushes away connection K2 downwards by the K1 place, gives roof pressure cylinder 10 electrical signal, roll sleeve 5 is pushed into the K3 position by the K7 position, hold out against roll riveting axle 15, position and compress by 14 pairs of metal axial-flow fan right-hand members of spring by hold-down head 13 simultaneously, left end is located and is compressed by compressing member 20.This moment, K3 connected 15 rotations of motor 2 operation drive roll riveting axles, and hydraulic system 11 actions are by oil cylinder 6 and cylindricality tooth bar 7 control screw mandrels 8 forward rotation.2 groups of tool tip 17 move inward respectively, the roll riveting action is carried out in the mid-game of the 19 pairs of metal axial-flow fans of hobboing cutter on it, be riveted to K5 place oil cylinder 6 and cylindricality tooth bar 7 control screw mandrels 8 backward rotation, 2 groups of tool tip 17 are outwards moved respectively, withdraw from riveting status at this moment motor 2 stop operating, tool tip 17 retreats to the K6 place, roof pressure cylinder 10 retreats to K7, K7 connection tailstock cylinder 9 gets electric, retreats to the K1 initial position, and K1 connects and disconnects all working program.For riveted joint next time is prepared.By regulating K5, K6, can adjust the depth of cut and the backhaul distance of tool tip 17.
The foregoing description only is a this patent mode of execution preferably, and for example the quantity of hobboing cutter 19 can be adjusted according to the increase and decrease of impeller mid-game quantity, and corresponding adjustment can be done according to the length of impeller in hobboing cutter 19 position on guide rail 18.The structure that all employing the technical program are described, feature and the variation on its spiritual principle, modification all belong to the protection domain of this patent.
