Description
Technical field
The utility model relates to a kind of bending machine, particularly relates to a kind of variable speed feeding device device of bending machine.
Background technology
General bending machine is in order to reach the crooked purpose of pipe fitting, and in order to meet the demand of processing, and it is slower to be that the speed when carrying out bend pipe of making needs, and the feeding speed behind the bend pipe then needs very fast.And all be provided with the variable speed feeding device device on the general bending machine to meet above-mentioned process requirements.
As shown in Figure 1 and Figure 2, the variable speed feeding device device 1 of existing a kind of bending machine is mounted on the end face of a board, and can drive the length direction generation displacement of a pipe fitting along this board.The first pinion gear unit 5 and one that second electromagnetic clutch 4, that this variable speed feeding device device 1 comprises first electromagnetic clutch 3 of a power source 2, an a pair of line shaft 201 that should power source 2, be located at these first electromagnetic clutch, 3 one sides in the lump is installed in these first electromagnetic clutch, 3 one sides is installed in the second pinion gear unit 6 between the first pinion gear unit 5 and first electromagnetic clutch 3.
This first pinion gear unit 5 has first erratic star wheel 502, that one first sun gear 501, one first rim gear wheel 505, most rings be located between this first sun gear 501 and this first rim gear wheel 505 and is subjected to the first wandering star jib 503 and of aforementioned first erratic star wheel, 502 interlocks to be installed in the output wheel 504 of these first wandering star jib, 503 bottoms.This second pinion gear unit 6 has second sun gear 601 corresponding to this first electromagnetic clutch 3, one second rim gear wheel 604, most individual second wandering star jib 603 that second erratic star wheel 602 and that is located between this second sun gear 601 and this second rim gear wheel 604 is subjected to aforementioned second erratic star wheel, 602 interlocks that encircles, and wherein this second wandering star jib 603 is affixed with this first sun gear 501.
When this first electromagnetic clutch 3 is the ON state, and when second electromagnetic clutch 4 is the OFF state, line shaft 201 outputting powers of this power source 2, can be through the suction magnetic action of this first electromagnetic clutch 3 with this second, one pinion gear unit 6,5 of transmission of power, driving the rotations that this output wheel 504 produces at a slow speed, and make this variable speed feeding device device drive pipe fitting to carry out at a slow speed bend pipe action.
On the contrary, when this second electromagnetic clutch 4 is the ON state, and when first electromagnetic clutch 3 is the OFF state, line shaft 201 outputting powers of this power source 2, can see through that driving wheel group 7 is passed to this second electromagnetic clutch 4 on one, and the suction magnetic action that utilizes this second electromagnetic clutch 4 utilize again driving wheel group 8 with transmission of power to this second wandering star jib 603, because of this second wandering star jib 603 and this first sun gear 501 affixed, produce rotation fast so borrow this first pinion gear unit 5 can drive this output wheel 504, and make this variable speed feeding device device drive pipe fitting carry out the action of feeding fast.

As shown in Figure 6, when needing the fast feed feeding behind the bend pipe, the piston rod 272 that can start this actuator 27 is done the action of retraction with respect to this cylinder body 271, and make this switch piece 25 be subjected to this brake 26 to drive and move to a second place, then big transfer wheel 252 is separated with this little driving wheel 23, and 251 of little transfer wheels and 22 engagements of pairing big driving wheel.At this moment, power output shaft 11 outputting powers of this power source 10,22 of this big driving wheels drive this little transfer wheel 251 and rotating shaft 24 produces the speedup rotation, and utilize this rotating shaft 24 can be with transmission of power to this deceleration unit 30, last then utilize the engagement of stopper wheel 33 and this tooth bar 250, can carry out fast feed feeding purpose.
Therefore, the utility model utilizes the handover operation of this switch piece 25, just can reach the purpose of operation of deceleration bend pipe and speedup feeding, and has following effect:
One, these switch unit 20 inside have good large and small driving wheel of rigidity 22,23 and little, big transfer wheel 251,252, so when power transmits, be not easy to produce back clearance, increase, back clearance can not be affected yet even exert oneself, and more can not influence pushing precision, the bend pipe size that is bent is more accurate.
Two, this switch unit 20 is not provided with electromagnetic clutch, and just just can reach the speed change purpose with the displacement of switch piece 25, not only Zheng Ti volume little, take up room also little.
Three, the utility model is not provided with electromagnetic clutch, so cost is lower, and large and small driving wheel 22,23 and little, big transfer wheel 251,252 and other parts can be lubricated operation smoothly, and the maintenance of part is simpler and easy.
Again as shown in Figure 7, the variable speed feeding device device 100 ' of the utility model second embodiment includes the deceleration unit 30 ' that switch unit 20 ' and that a power source 10 ', is installed in this power source 10 ' one side is installed in this switch unit 20 ' one side.This power source 10 ' is same as the previously described embodiments, and the rotating shaft 24 ' of this switch unit 20 ' is that inputting shaft 31 ' with this deceleration unit 30 ' connects to one.
The big driving wheel 22 ', one that this switch unit 20 ' has a more number of teeth is located at this big driving wheel 22 ' below and is had the middle driving wheel 231 ' of little driving wheel 23 ' and between this large and small driving wheel 22 ', 23 ' of the less number of teeth.This switch piece 25 ' also have one can be in good time and this big driving wheel 22 ' little transfer wheel 251 ', of producing engagement and having a less number of teeth be located at this little transfer wheel 251 ' below and can be in good time with should little driving wheel 23 ' produce the big transfer wheel 252 ' that meshes and between this little, big transfer wheel 251 ', 252 ' and can be in good time and the intermediate transfer that meshes of this centre driving wheel 231 ' take turns 257 '.
As shown in Figure 7, when this switch piece 25 ' during in a primary importance, this big transfer wheel 252 ' and pairing little driving wheel 23 ' engagement, just can utilize this rotating shaft 24 ' directly power to be seen through this inputting shaft 31 ' and is passed to this deceleration unit 30 ', and utilize cooperating of this little driving wheel 23 ' and this big transfer wheel 252 ', can reach the deceleration purpose, to carry out the operation of heavy load bend pipe.
Again as shown in Figure 8, when the retraction action of the piston rod 272 ' that starts this actuator 27 ' with respect to first section in this cylinder body 271 ' work, and make this switch piece 25 ' driven by this brake 26 ' and when moving to a second place, then big transfer wheel 252 ' is separated with this little driving wheel 23 ', and intermediate transfer wheel 257 ' then meshes with pairing middle driving wheel 231 '.At this moment, the power output shaft 11 ' outputting power of this power source 10 ', this centre driving wheel 231 ' then drive this intermediate transfer wheel 257 ' and rotating shaft 24 ' produces the rotation of slowing down, and also can reach a midrange speed, to carry out operation of light load bend pipe or feeding operation.
Again as shown in Figure 9, when the retraction action of the piston rod 272 ' that starts this actuator 27 ' with respect to second section in this cylinder body 271 ' work, and make this switch piece 25 ' driven by this brake 26 ' and when moving to one the 3rd position, then intermediate transfer wheel 257 ' separates with this centre driving wheel 231 ', and little transfer wheel 251 ' then meshes with pairing big driving wheel 22 '.At this moment, the power output shaft 11 ' outputting power of this power source 10 ', this big driving wheel 22 ' then drive this little transfer wheel 251 ' and rotating shaft 24 ' produces the speedup rotation, also can reach the speedup purpose, can carry out the quick feeding operation.
Therefore, the utility model second embodiment compares with existing variable speed feeding device device, has three sections speed changing functions.
