Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Pneumatic automatic bending machine comprises main support 1, power supply 2, source of the gas 3, latch assembly, foldable component, inductor 4 and controller 5.The front-back of described main support 1 the first half is provided with chute 6.Described latch assembly comprises locking die, support bar 7, be positioned at locking die both sides and two fixed heads 8 be welded on main support 1 and being fixed on main support 1 and the first cylinder 9 of start in the horizontal direction.Described locking die comprises the patrix 11 and counterdie 12 that are all provided with locking slot 10.Described fixed head 8 is provided with holddown groove 13, and the size of holddown groove 13 and the thickness of locking die match, and locking die the right and left stretches in the holddown groove 13 of fixed head 8.Locking die is blocked by the holddown groove 13 on fixed head 8 in the utility model, namely belong between locking die with fixed head 8 and be flexibly connected, user can design many moneys locking die as required, in specific operation process, by changing locking die, bending is carried out to different workpiece, thus expand the scope of application of pneumatic automatic bending machine.The counterdie 12 of described locking die is provided with baffle 14, and baffle 14 is provided with locking slot 10, and the shape of locking slot 10 is identical with counterdie locking slot 10, and the top of baffle 14 overlaps with the top of counterdie 12.Baffle 14 is for the protection of by bending workpieces.The straight glue mouth copper bar of such as the utility model on the bending inner tube of a tyre; after locking die patrix 11 and counterdie 12 close; because there is the existence of baffle 14; the junction of glue mouth copper bar and inner tube of a tyre distance patrix 11 is made to have a segment distance with the closure edge place of counterdie 12; when being carried out bending by bending workpieces to glue mouth copper bar, can effectively avoid causing damage to the junction of glue mouth copper bar and the inner tube of a tyre.The upper end of described support bar 7 is connected with piston rod 16 end that the first cylinder 9 is positioned at outside cylinder through the chute 6 on main support 1 by connecting rod 15, and the length of the first cylinder piston rod 16 is arranged so that when support bar 7 moves to and support bar 7 stop motion during horizontal plane position.The lower end of support bar 7 is connected with the patrix 11 of locking die by bolt, and described first cylinder 9 is connected with source of the gas 3 by the first magnetic valve 17.Described foldable component comprises base 18, the drift 19 be arranged on base, pedestal 20, be arranged on adjusting bolt 21 on pedestal 20 and locking nut 22 and be fixed on main support 1 and the second cylinder 23 of vertically start.Described base 18 is provided with waist through hole 24, and when the position of front and back adjustment base 18, pedestal 20 and base 18 connect through waist through hole 24 by connector.Described drift 19 outer cover is equipped with protective sleeve 25, and protective sleeve 25 can rotate around drift 19 central shaft.Described protective sleeve 25 can effectively prevent drift 19 from damaging by bending workpieces.Protective sleeve 25 adopt nylon or other with nylon, there is material that is identical or similar performance and make.Piston rod 26 end that described second cylinder 23 is positioned at outside cylinder is connected with pedestal 20, and the second cylinder 23 is connected with source of the gas 3 by the second magnetic valve 27.Described inductor 4 is positioned at drift 19 rear and is fixed on support 28, and described support 28 is connected with pedestal 20, base 18 by hold-down bolt 29, and when patrix 11 closes with counterdie 12, the height of locking slot 10 is corresponding with the height of inductor 4.Described adjusting bolt 21 and locking nut 22 are for the distance of adjusting base 18 apart from locking die, and then adjustment bending angle.When needs increase bending angle, operator first adjusts loose nuts 22 and hold-down bolt 29, then to locking die direction adjustment adjusting bolt 21, reduces the distance of base 18 apart from locking die, thus increases bending angle.When needs reduce bending angle, operator first adjusts loose nuts 22 and hold-down bolt 29, then to locking die rightabout adjustment adjusting bolt 21 and base 18, increases the distance of base 18 apart from locking die, thus reduces bending angle.Compared with direct movable base 18, adopt adjusting bolt 21 to carry out adjustment and be conducive to control accuracy.Time relay module 30 is provided with in described controller 5, the timing from during the first cylinder 9 start of described time relay module 30, the setting range of the delay time t of time relay module 30 is 0.5s ~ 1s, and when after the t time, controller 5 controls foldable component and starts start.Inductor 4, first magnetic valve 17 and the second magnetic valve 27 are electrically connected with controller 5.
Specific works process:
When not working, support bar 7 is positioned at the left end of chute 6.After starting power supply 2, operator puts into locking slot 10 by needing the workpiece of bending, and promotes by bending workpieces to the direction of inductor 4, makes inductor 4 existence of workpiece can be detected.Inductor 4 is by the Signal transmissions that detects to controller 5, and controller 5 exports control signal according to this signal, and control the first magnetic valve 17 and open, the first cylinder 9 is started working.The start of the first cylinder 9 makes support bar 7 move right, and stops with during horizontal plane position when support bar 7 moves to, and now patrix 11 and counterdie 12 close thus will be fixed in locking slot 10 by bending workpieces.From the first cylinder 9 after start through the t time, controller 5 controls the second magnetic valve 27 and opens, and the second cylinder 23 is started working.The start of the second cylinder 23 makes pedestal 20 move upward, and base 18 moves upward together along with pedestal 20, and then the drift 19 on band moving base 20 moves upward, thus realizes the bending to workpiece.
To sum up, the utility model produces a desired effect.
