Description

Curved Continuous hair style bending machine

The utility model relates to a kind of bending machine, especially refers to bend the bending machine of the condenser pipe with multiple elbow.

At present, during the condenser pipe of traditional fabrication air conditioner, be employing metal tube is relied on a fixing elbow, then be bent to form condenser pipe in the manual mode such as beat that cooperates, the method is not only quite time-consuming, effort, even need suitable technically, so manufacturing cost is high.

The bending machine of commonly using, as shown in Figure 1, its overall workflow system is controlled with a programmable microcontroller, after metal tube is sent to the single elbow seat of tail end, borrow the rotation of elbow seat to close the suitable angle of rotation, metal is bent an elbow, this kind bending machine is because of being limited in the design of single elbow seat, can only bend two elbows at most, that is commonly use the elbow that bending machine can't bend out all strokes of condenser pipe automatically, can only after bending out two elbows,, then make the bending machine action bend out two elbows again manually metal tube is rotated 180 degree angles, afterwards again through artificial rotation 180 degree angles, so repeat aforementioned activities,, can produce condenser pipe with multiple elbow with artificial cooperation bending machine interworking.Though it is fast, technical also simpler that the method is made than traditional-handwork,, the effect and the processing procedure that still do not have the automatic moulding condenser pipe do not have continuity intermittently, also quite time-consuming on making in addition, can't realize a large amount of productions, still do not possess the usability on the industry.

In view of this, the purpose of this utility model provides a kind of Curved Continuous hair style bending machine, and it is to carry out bending action by two groups of interlaced metal tubes that are aligned in of elbow seat, and then can bend out continuous elbow automatically.

The purpose of this utility model is achieved in that a kind of continuous elbow bending machine comprises board, the support disc seat of bearing drum, aligner, chuck, cutter and elbow seat, wherein chuck is slidingly arranged on the board, this chuck bottom side connects in the board with driving screw, aligner is between chuck and the support disc seat, the roller facing each other of several band semicircle guide grooves is set on this aligner, cutter is on the board left end, and the elbow seat is arranged on the board tail end, it is characterized in that: board tail end bottom transverse is provided with a traverse rod, slide on this traverse rod and establish a slide, two groups of mutual transversely arranged elbow seats are set above the slide again, and elbow seat below respectively is provided with the elevating oil cylinder that is fixed on above the slide.

Described elbow seat is provided with rotatable 180 ° of elbow anchor clamps and this elbow anchor clamps.

Owing to adopt such scheme: owing to can realize bending out the pipe of multiple elbow, production cost reduces greatly.

Present embodiment, shown in Fig. 2,3, it is to be provided with aligner 3, chuck 4 and cutter 5 for the bearings bundle on the board 1 around the drum 21 of metal tube 22 that system is provided with by a support disc seat 2, these drum 21 bundles around metal tube 22 be to affect by the chuck 4 that is slidingly installed on the board 1,4 of this chucks borrow the driving screws 41 of bottom side to cooperate motors 42, but and longitudinal sliding motion on board 1; And 2 set aligners 3 of chuck 4 and support disc seat are to be provided with some have semicircle guide groove 32 and rollers facing each other 31, when chuck 4 affects metal tube 22 through aligner 3, can borrow the semicircle guide groove 32 of aligner 3 some rollers 31 with metal tube 22 straightenings; The metal tube 32 part system that stretches out chuck 4 passes a cutter 5, the elbow seat 7 of board 1 tail end that then leads in addition; Present embodiment is mainly improved part and is: board 1 tail end bottom is horizontally set one traverse rod 6, the sliding slide 61 of establishing on this traverse rod 6, this slide 61 is driven by a lateral oil cylinder pressure 62 and slidably on traverse rod 6, table system is provided with transversely arranged mutually and elbow seat 7 belows of two groups of elbow seats 7 and respectively is provided with an elevating oil cylinder 63 that is fixed on table on the slide 61 on the slide 61 again, borrows the setting of each elevating oil cylinder 63 can control the 7 interlaced liftings of two groups of elbow seats; These elbow seat 7 top cordings have a stationary fixture 71 and elbow anchor clamps 72, and these elbow anchor clamps 72 are to be connected with in a rotating shaft 73, when this rotating shaft 73 is rotated, but interlock elbow anchor clamps 72 rotations 180 degree angles.

Cooperate elevating oil cylinders 63 and the design and the laterally design of slippage of slide 61 of the lifting that can interlock by above-mentioned two groups of elbow seats 7, can make to be positioned at upper elbow seat 7 and to be aligned in metal tube 22 from board 1.When utilizing the present embodiment bending, as: when air conditioner has the condenser pipe of multiple elbow, system utilizes chuck 4 with the metal tube elbow seat 7 that leads, certainly one elbow seat 7 is must be first traversing and rise to corresponding metal tube 22 places (as shown in Figure 4), utilize moving back and forth of chuck 4 to make metal tube 22 suitably stretch out elbow anchor clamps 72 (as shown in Figure 5) and then control this elbow anchor clamps 72 actions, with metal tube 22 twisted rotary shafts 73 bendings 180 degree (as shown in Figure 6), controlling chuck 4 delivery metal tubes 22 again advances suitably apart from (as shown in Figure 7), and control elevating oil cylinder 63 descends (as shown in Figure 8) elbow seat 7, lateral oil cylinder pressure 62 actions simultaneously go into to make slide 61 traversing, and make the elevating oil cylinder 63 of another elbow seat 7 move, make 7 alignment of elbow seat bend the metal tube 22 (as shown in Figure 9) of an elbow, control the elbow anchor clamps action of elbow seat 7 then, metal tube 22 is spent (as shown in figure 10) towards bending 180 with aforementioned opposite direction, according to aforementioned program, interior chuck 4 continues to be interrupted feeding metal tube 22, cooperate two groups of elbow seats, the 7 staggered bending actions of replacing, can finish the continuous elbow of metal tube 22 easily, and after finishing the continuous elbow of preset length, control cutter 5 is cut off metal tube 22, to make the condenser pipe with multiple elbow automatically.
