Specific embodiment

As shown in Figs 1-4, a kind of four fluorine tube hemmer, including Support bracket 1, flange positioning device 2.

The Support bracket 1 includes pedestal 3, and pedestal 3 is fixedly connected by expansion bolt with ground, is equipped on the base 3 One sliding rail 4, front and back radial symmetric is equipped with centering body 5 on sliding rail 4, is then set between centering body 5 there are two jacking mechanism 6, Centering body 5, jacking mechanism 6 are for four fluorine tube to be fixed.And 3 front end of pedestal is equipped with positioning mechanism, localization machine Structure is for determining that four fluorine tube needs flanging length and be supported to facilitate later period flange.

Specifically, the centering body 5 includes first leg 7, and first leg 7 is slidably arranged on sliding rail 4, when sliding into It can be locked on sliding rail 4 by the bolt in 7 bottom end through-hole of first leg behind designated position.7 top of first leg is equipped with crossbeam 8, surrounding is connected with thread bush 9 on crossbeam 8, and screw rod 10 is threaded on thread bush 9；Make when rotating outward screw rod 10, by spiral shell The strut then overall elongated that line set 9, screw rod 10 are formed, it is on the contrary then shorten.And every 10 end of screw rod is equipped with ballhead, in strut After being elongated to appropriate length, ballhead can be held out against on tetrafluoro inside pipe wall.In order to realize centering, i.e., to guarantee the length of every strut Degree is consistent, can be coated with different colours index line along its length on screw rod 10, the index line of different colours represents difference The internal diameter of four fluorine tube.

The jacking mechanism 6 includes the second supporting leg 11, and the second supporting leg 11, which is equipped with, adjusts ring 12, and the diameter for adjusting ring 12 is wanted More than or equal to the diameter of maximum specification size four fluorine tube.Multiple screw rods 13,13 end of screw rod are circumferentially on adjusting ring 12 Equipped with arc panel 14.When needing to hold out against, four fluorine tube is passed through and adjusts ring 12, is then threaded into screw rod 13, pushed up using arc panel 14 Tightly on the outer wall of four fluorine tube.Since centering body 5 completes centering in advance, screw rod is screwed into the length adjusted in ring 12 It is consistent.

The positioning mechanism includes the upright slide rail 15 that pedestal 3 or so is arranged in, along perpendicular on two upright slide rails, 15 opposite face Histogram is to U-type groove is equipped with, and two upright slide rails 15 are provided with sliding slot 18 close to the end face of 6 side of jacking mechanism along the vertical direction, sliding Slot 18 is connected to U-type groove.It is slidably arranged in U-type groove at left and right sides of positioning disk 16 by sliding block, the thread head 17 of sliding block side It is fixed that it can be held in position disk 16 in this way by nut check after stretching out outside sliding slot 18.

Here positioning disk 16 includes the positioning ring of front end and the semicircular ring of rear end, the internal diameter and four of positioning ring and semicircular ring Fluorine pipe outside diameter is identical, and positioning ring inward flange to the length between outer edge is slightly larger than flanging length.It can be according to the four of different size Fluorine pipe customizes positioning disk 16 of corresponding size, as long as guaranteeing corresponding inner hole and the mating achievable socket of four fluorine tube.

On 16 top of positioning disk, correspondence is hinged with connecting-rods with constant lengh 26, the connecting-rods with constant lengh 26 on different positioning disks 16 and the positioning disk 16 Matched four fluorine tube needs flanging length corresponding, and such flange elongation can directly determine.

In addition, 8 front end of crossbeam is equipped with multi-diameter shaft 27,27 diameter of multi-diameter shaft is gradually reduced from one end to the other end.It should Structure can be directed to the lesser four fluorine tube of specification, be socketed using the different Duan Keyu four fluorine tubes of multi-diameter shaft 27, in this way can be voluntarily Centering facilitates jacking mechanism 6 to clamp.

Specifically, the flange positioning device 2 includes mounting base 19, and 19 front end of mounting base is respectively arranged on the left side and the right side taper Heat flange body 20, stock mould 21, wherein taper heat flange body 20, stock mould 21 referring to application No. is The patent " a kind of four fluorine tube Quick flanging device " of " 201721361901.9 ".19 rear end of mounting base is connect with motor 22, motor 22 are slidably arranged on slide 24 by bracket 23 and push back-and-forth motion by cylinder 25.Here motor and the successive of cylinder move Control is adjusted by single-chip microcontroller in work.Single-chip microcontroller also controls the temperature of taper heating flange body 20 simultaneously.

Here 8 cross section of crossbeam is square, square center, multi-diameter shaft 27 axis, adjust ring 12 axis, Axis point coincidence on corresponding perspective plane of postrotational taper heating 20 axis of flange body, postrotational stock mould 21, this Sample no matter the axis after the four fluorine tube installation of which kind of specification be located at the axis of taper heating flange body 20, stock mould 21 it is same On straight line, guarantee that molding is met the requirements.

Operation principle and process: when needing the four fluorine tube to a certain specification to carry out flange, four fluorine tube is passed through adjust first Ring 12 is saved, and the screw rod 10 etc. for making two centering bodies 5 is extend into four fluorine tube from four fluorine tube both ends, then adjusts each screw rod 10, keep four 10 extension elongations of screw rod identical and hold out against on four fluorine tube, can guarantee center and the tetrafluoro tube hub of crossbeam in this way Substantially in same point, it may make that four fluorine tube holding is horizontal by the adjusting of two centering bodies 5.Then locking screw 13, so that two tops Tight mechanism 6 constitutes an entirety with four fluorine tube.The centering body 5 close to positioning mechanism side is removed, by two jacking mechanisms 6 and four The whole forward movement that fluorine pipe is constituted, and four fluorine tube is made to stretch out 16 certain length of positioning disk, connecting-rods with constant lengh 26 is rotated, connecting-rods with constant lengh is made 26, which are horizontally directed to four fluorine tube, stretches out one end, and with four fluorine tube extension end in face of neat, such four fluorine tube extension elongation is to need to turn over Edge lengths.Then the bolt of 11 lower end of the second supporting leg of two jacking mechanisms 6 is fixed, so that two jacking mechanisms 6 are kept with four fluorine tube It is fixed.

Then controller controls corresponding cylinder 25 and stretches out, so that the taper heating flange body 20 under temperature constant state protrudes into It being heated in four fluorine tube, certain time exhaust hood 25 retracts, and then motor drives mounting base 19 to rotate 180 degree, so that Stock mould 21 and four fluorine tube face, cylinder 25 stretch out again, and 21 thinner section of stock mould is extend into four fluorine tube, 21 rear end of stock mould Conical pipe face pressure after hot melt is put down and forms flange by big disk.
