Straight device all includes first group of pressure wheel and second group of pressure wheel, first group of pressure wheel and second group of pressure wheel meta arrangement and spacing
Adjusted by adjustment bolt, first group of pressure wheel from X to straightening device and second group of pressure wheel center line and Y-direction straightening device the
The center line of one group of pressure wheel and second group of pressure wheel overlaps.Described feed mechanism includes the upper and lower of more than 1 pair arranged opposite
Material feeding pressing wheel, upper and lower material feeding pressing wheel is driven by fan-shaped partial gear and rotating speed is identical, but direction of rotation is on the contrary, so as to real
The existing interval displacement of material in the horizontal direction, described shut-off mechanism realize cutting knife in vertical direction by cam and swing rod
It is upper and lower to move back and forth so as to realize surface trimming.But the device straightening mechanism is complicated and can not realize the Automatic-drawing of reinforcing bar
Function, and the device acts for batch (-type), and operating efficiency is relatively low.
The content of the invention
The purpose of the present invention is exactly to solve foregoing problems existing for prior art, there is provided a kind of automatic flattening cutting machine.For
Reach above-mentioned purpose, the technical scheme is that：
This bar straightening stretching cutting all-in-one machine, including preliminary straightener 1, stretching-straightening device 2, shearing device 3,
Unlike the prior art：Described preliminary straightener 1 includes the tubular body 11 that left end internal diameter is big, right-hand member internal diameter is small, pipe
Shape body 11 drives it to be rotated around reinforcing bar 5 by dynamical system, and more than 3 free rolls 12 are uniformly arranged on the inwall of tubular body 11,
0 ° -45 ° of angle α with tubular body bus be present in projection of the axial line of each free roll 12 on tubular body inwall.
Further, described stretching-straightening device 2 includes more than 2 pairs of carry-over pinch rolls 21, and each carry-over pinch rolls 21 pass through dynamic
The angular speed that Force system drives is equal, but the diameter of carry-over pinch rolls is from left to right gradually incremented by.
The present invention compared with prior art, simple in construction, continuous non-stop run, efficiency high, it is possible to achieve material from
Dynamic aligning, stretching, cut-out.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the left view at A-A in Fig. 1.
Embodiment
The present invention is further described referring to the drawings.
A kind of bar straightening stretching cutting all-in-one machine, including preliminary straightener 1, stretching-straightening device 2, shearing device 3,
Described preliminary straightener 1 includes the tubular body 11 that left end internal diameter is big, right-hand member internal diameter is small, and tubular body 11 passes through dynamical system band
Move it to rotate around reinforcing bar 5,3 free rolls 12 are uniformly arranged on the inwall of tubular body 11, the axial line of each free roll 12 is in pipe
30 ° of angle α with tubular body bus be present in the projection in shape body on wall.
In the course of the work, reinforcing bar 5 is worn below under the traction of stretching-straightening device 2 from the big one end of the internal diameter of tubular body 11
Enter, one end small from internal diameter, which passes, to continue uninterruptedly to move to the right, and whole tubular body 11 is rotated around reinforcing bar 5, tubular body 11
Inwall on be uniformly arranged 3 free rolls 12 and also rotated therewith around reinforcing bar 5, because free roll 12 is arranged in tubular body 11, because
The virtual cavity that one end is big, one end is small is also formed after the rotation of this free roll 12, the reinforcing bar 5 in virtual cavity carries bending,
Knee is inevitably that free roll 12 collides with the virtual body wall of virtual cavity, so as to which the reinforcing bar 5 of bending is preliminary
Aligning, because free roll 12 itself can only rotate relative to the inwall of tubular body 11, therefore can be in the moment contacted with reinforcing bar 5
Rotate, so as to avoid that reinforcing bar 5 is caused to damage.Simultaneously because projection of the axial line of each free roll 12 on tubular body inwall
30 ° of angle α be present with tubular body bus, thus it is namely parallel with tubular body bus when reinforcing bar 5 is more straight when, Bu Huiyu
Stuck phenomenon occurs for free roll 12, and so as to realize no matter which kind of irregular shape reinforcing bar 5 is, it can be become to preliminary straight.
Described stretching-straightening device 2 includes 4 pairs of carry-over pinch rolls, is from left to right the traction of the first carry-over pinch rolls 21, second respectively
Roller 22, the 3rd carry-over pinch rolls 23, the 4th carry-over pinch rolls 24, the angular speed that each carry-over pinch rolls are driven by dynamical system is equal, but second
The diameter of carry-over pinch rolls 22 is bigger 0.5cm than the diameter of the first carry-over pinch rolls 21, the diameter of the 3rd carry-over pinch rolls 23 is than the second carry-over pinch rolls 22
The big 0.5cm of diameter, the diameter of the 4th carry-over pinch rolls 24 are bigger 0.5cm than the diameter of the 3rd carry-over pinch rolls 23.
Become preliminary straight reinforcing bar 5 and enter the first carry-over pinch rolls 21, subsequently enter the second carry-over pinch rolls 22, due to the first traction
Roller 21 is equal with the angular speed of the second carry-over pinch rolls 22 and the diameter of the second carry-over pinch rolls 22 is bigger than the diameter of the first carry-over pinch rolls 21
0.5cm, that is, the linear velocity of the second carry-over pinch rolls 22 and the contact position of reinforcing bar 5 is than the first carry-over pinch rolls 21 and the line of the contact position of reinforcing bar 5
Speed is big, therefore can produce a stretching action to reinforcing bar 5, makes reinforcing bar 5 between the first carry-over pinch rolls 21 and the second carry-over pinch rolls 22
Produce certain stretching, the reinforcing bar 5 of this section can also become more straight simultaneously in drawing process, similarly the second carry-over pinch rolls 22 with
Identical stretching and aligning effect can be equally produced between 3rd carry-over pinch rolls 23, between the 3rd carry-over pinch rolls 23 and the 4th carry-over pinch rolls 24
Should, this stretching and the superposition of aligning effect, the final reinforcing bar 5 to leave after stretching-straightening device 2 become it is very straight simultaneously
And be also stretched and eliminate prestressing force, meet the needs of construction, specific extensibility can be by setting each carry-over pinch rolls
Diameter adjusted, be allowed to meet defined extensibility.
Shearing device is that cutting knife is completed to cut off reinforcing bar using vertical cut-out mode, and cutting knife can use cam mechanism to adopt
The mechanical structure that gyration is converted to linear reciprocating motion generally used in the prior art with rack-and-pinion etc., so as to real
Reinforcing bar 5 now is cut off according to the length of setting, it will not go into details herein.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to is assert
The specific implementation of the present invention is confined to these explanations.For the those of ordinary skill belonging to the present invention, this is not being departed from
On the premise of thinking of the present invention, simple deduction or replace can also be made, should all be considered as belonging to protection scope of the present invention.
