Abstract
The invention discloses a feeding mechanism of a tubing chipless cutter, comprising a rotary wheel, a tool apron and a toothless cutter, wherein a through hole for the tubing to pass is manufactured along the center shaft of the rotary wheel, the tool apron and the rotary wheel are in radial sliding, a lever is hinged at the rotary wheel, one end of the lever is hinged with a connecting rod, the other end is provided with a bob-weight block, the other end of the connecting rod, which is hinged with the lever, is hinged with the tool apron, and a reset spring is arranged between the rotary wheel and the lever. After the above technical scheme of arranging a locating part for limiting the rotary amplitude of the lever on the rotary wheel is used, feeding is realized by centrifugal force difference, thus saving various electrical appliances and power source devices of the existing feeding mechanism, simplifying feeding mechanism and lowering the production cost and maintenance ratio of the device.
Description
Technical field:
The invention belongs to tubing cutter sweep technical field, refer in particular to a kind of delivering gear of pipe no-chip cutting machine.
Background technology:
But the pipe no-chip cutting machine is to utilize the anodontia cutting knife of disk of rotation to revolve round the sun around the tubing circumferencial direction; the feed while revolving round the sun; from the tube outer diameter to the internal diameter, successively cut; thereby realize the chipless cutting; though the tubing that this chipless cutting machine cuts out does not produce the bits material; section is smooth; do not need the secondary operations section; but there is shortcoming; mainly be that its feed is to promote the anodontia cutting knife realization of disk by the cylinder that is arranged on the runner; this just requires to be provided with multiple electrical equipments such as brush on runner and lathe, structure is quite complicated, the manufacturing cost height; the maintenance probability is big; for example when brush wear or the damage of other electrical equipment, just need to shut down to change, influence and produce.
Summary of the invention:
The objective of the invention is in order to overcome the shortcoming of above-mentioned prior art, the pipe no-chip cutting machine delivering gear of a kind of simple in structure, maintenance rate and low cost of manufacture is provided.
For achieving the above object, technical scheme provided by the invention is: the delivering gear of pipe no-chip cutting machine, include runner, tool rest and anodontia cutting knife, be processed with the through hole that passes for tubing along the runner axis, tool rest becomes to radially slide with runner, is hinged with lever on runner, and an end of this lever is hinged with connecting rod, the other end is provided with balancing weight, and is hinged with the hinged other end and the tool rest of lever on connecting rod.
Be connected with back-moving spring between runner and the lever.
The locating part of restriction lever rotation amplitude is installed on runner
After adopting technique scheme, utilize the centrifugal force difference to realize feed, saved the various electric equipments and the power source of existing delivering gear, simplified delivering gear, reduced the manufacturing cost and the maintenance rate of equipment simultaneously.
Description of drawings:
Fig. 1 is the pipe no-chip cutting machine structure figure that the present invention only is provided with the anodontia cutting knife of a disk;
Fig. 2 is the structure chart that the present invention is provided with three disk no-tooth swivel wheel parts.
The specific embodiment:
Now in conjunction with the accompanying drawings 1 and accompanying drawing 2 elaborate the present invention:
The pipe no-chip cutting machine delivering gear of present embodiment includes the anodontia cutting knife 3 of runner 2, tool rest 8 and disk, be processed with the through hole 11 that passes for tubing 1 along the runner axis, disk is anodontia, and cutting knife 3 is free to rotate, runner 2 is provided with the middle part lever 4 hinged with runner 2, one end of this lever 4 is hinged with connecting rod 12, the other end is provided with balancing weight 5, and is hinged with the hinged other end and the tool rest 8 of lever 4 on connecting rod 12.End at lever 4 configuration balancing weights 5 is provided with the back-moving spring 6 that connects runner 2, and this back-moving spring 6 plays balancing weight 5 reset responses when assisting runner 2 reduction of speed stalls.The operative end surface of runner 2 is provided with radial groove 7, and the tool rest 8 of the anodontia cutting knife 3 of disk cooperates slip with radial groove 7, cooperate slip by tool rest 8 with radial groove 7, radially feed of the anodontia cutting knife 3 of disk when guaranteeing runner 2 rotations, runner 2 is provided with locating part 13, this locating part 13 is a portal frame, lever 4 passes portal frame, lever 4 rotation processes will be limited when running into the portal frame upper limb to rotate, realization guarantees that to the position-limiting action that lever 4 rotates feed does not exceed setting range.
Accompanying drawing 1 is for only being provided with the cutting machine of an anodontia cutting knife 3 of disk, but on the operative end surface of runner 2, be provided with the support wheel 9 of a pair of rotation with the anodontia cutting knife of disk 3 symmetry places, the tubing 1 that passes from runner 2 axle center places between the two supports wheel 9, but the pressure during cutting knife 3 feeds that the existence balance disk of two supports wheel 9 is anodontia, in addition for the centrifugal force of the anodontia cutting knife 3 of balance disk with balancing weight 5 generations that are mated, guarantee the alignment that runner 2 rotates, be provided with another balancing weight 10 in a side of anodontia cutting knife 3 symmetries of disk.
Fig. 2 is the cutting machine that is provided with three anodontia cutting knifes 3 of disk, and these three disks are anodontia cutting knife 3 evenly distributes along circumference, and the centrifugal force on can Balance rotary wheel 2 when rotating like this guarantees the alignment that runner 2 rotates.
The operation principle of this delivering gear is: when runner 2 rotates, balancing weight 5 and disk are anodontia, and cutting knife 3 rotates together, the anodontia cutting knife 3 of balancing weight 5 and disk all can produce centrifugal force in the rotating process, by the weight of balancing weight 5 is set, make big than the anodontia cutting knife 3 of disk of centrifugal force that balancing weight 5 produces, lever 4 end that is provided with balancing weight 5 outwards rotates like this, correspondingly the other end rotates to the axle center, at this moment by connecting rod 12 transmissions, driving tool rest 8 and the anodontia cutting knife 3 of disk radially chute 7 slide to tubing 1 to be cut, realize the action of feed.
Compare with existing cutting machine, saved various power sources such as cylinder, correspondingly also saved and driven the required various electrical equipments of power source, greatly simplify the structure, reduce manufacturing cost.
The embodiment of the above is preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so the equivalence that all shapes according to the present invention, structure and principle are done changes, all should be covered by in protection scope of the present invention.
