Description
Technical field
The present invention relates to building machinery, particularly a kind of bar straightening stretching cutting all-in-one machine.
Background technology
On building sites, amount of reinforcement is larger, and artificial straightening, cutting, both took a lot of work, require great effort in the past, has easily to mix up in quantity and length, disarray.Though there be the Chinese invention patent of some automation equipments if publication number is CN203245316U to disclose a kind of automatic flattening cutting machine, comprise straight line straightening device, feed mechanism, shut-off mechanism, described straight line straightening device is made up of to straightening device 1 and Y-direction straightening device X, X is mutually vertical with Y-direction straightening device to straightening device, X comprises first group of pressure wheel and second group of pressure wheel to straightening device and Y-direction straightening device, between first group of pressure wheel and second group of pressure wheel position arrangement and spacing by adjustment bolt adjustment, X overlaps to first group of pressure wheel of straightening device and the center line of second group of pressure wheel with the center line of first group of pressure wheel of Y-direction straightening device and second group of pressure wheel.Described feed mechanism comprises 1 upper and lower material feeding pressing wheel to above arranged opposite, upper and lower material feeding pressing wheel is by fan-shaped partial gear transmission and rotating speed is identical, but direction of rotation is contrary, thus realizing material interval displacement in the horizontal direction, described shut-off mechanism realizes cutting knife upper and lower reciprocating motion in vertical direction by cam and fork thus realizes surface trimming.But this device straightening mechanism is complicated and cannot realize the Automatic-drawing function of reinforcing bar, and this device is batch (-type) action, and operating efficiency is lower.
Summary of the invention
Object of the present invention solves the foregoing problems that prior art exists just, provides a kind of automatic flattening cutting machine.For achieving the above object, technical scheme of the present invention is:
This bar straightening stretching cutting all-in-one machine, comprise preliminary straightener 1, stretching-straightening device 2, shearing device 3, unlike the prior art: described preliminary straightener 1 comprises the tubular body 11 that left end internal diameter is large, right-hand member internal diameter is little, tubular body 11 drives it to rotate around reinforcing bar 5 by dynamical system, the inwall of tubular body 11 is evenly arranged more than 3 free rolls 12, and the projection on tubular body inwall of the axial line of each free roll 12 and tubular body bus exist the angle α of 0 °-45 °.
Further, described stretching-straightening device 2 comprises 2 to above carry-over pinch rolls 21, and the angular speed that each carry-over pinch rolls 21 are driven by dynamical system is equal, but the diameter of carry-over pinch rolls from left to right increases progressively gradually.
Compared with prior art, structure is simple, and continuous non-stop run, efficiency is high, can realize the automatic flattening of material, stretching, cut-out in the present invention.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the left view at A-A place in Fig. 1.
Detailed description of the invention
With reference to accompanying drawing, the present invention is further described.
A kind of bar straightening stretching cutting all-in-one machine, comprise preliminary straightener 1, stretching-straightening device 2, shearing device 3, described preliminary straightener 1 comprises the tubular body 11 that left end internal diameter is large, right-hand member internal diameter is little, tubular body 11 drives it to rotate around reinforcing bar 5 by dynamical system, the inwall of tubular body 11 is evenly arranged 3 free rolls 12, and the projection on tubular body inwall of the axial line of each free roll 12 and tubular body bus exist the angle α of 30 °.
In the course of the work, penetrate from one end that tubular body 11 internal diameter is large under the traction of reinforcing bar 5 stretching-straightening device 2 below, pass from one end that internal diameter is little and continue uninterrupted motion to the right, and whole tubular body 11 rotates around reinforcing bar 5, the inwall of tubular body 11 is evenly arranged 3 free rolls 12 also to rotate around reinforcing bar 5 thereupon, because free roll 12 is arranged in tubular body 11, therefore one end is also formed after free roll 12 rotation large, the virtual cavity that one end is little, be positioned at the reinforcing bar 5 of virtual cavity with bending, knee inevitably collides with the virtual body wall of virtual cavity and free roll 12, thus bending reinforcing bar 5 is tentatively aligned, because free roll 12 itself can only have rotation relative to the inwall of tubular body 11, therefore can rotate in the moment contacted with reinforcing bar 5, thus avoid causing damage to reinforcing bar 5.Simultaneously because the projection on tubular body inwall of the axial line of each free roll 12 and tubular body bus exist the angle α of 30 °, therefore time namely parallel with tubular body bus when reinforcing bar 5 is more straight, stuck phenomenon can not be there is with free roll 12, thus realize no matter reinforcing bar 5 is which kind of is irregularly shaped, all it can be become tentatively straight.
Described stretching-straightening device 2 comprises 4 pairs of carry-over pinch rolls, from left to right the first carry-over pinch rolls 21, second carry-over pinch rolls 22, the 3rd carry-over pinch rolls 23, the 4th carry-over pinch rolls 24 respectively, the angular speed that each carry-over pinch rolls are driven by dynamical system is equal, but the diameter of the second carry-over pinch rolls 22 0.5cm larger than the diameter of the 3rd carry-over pinch rolls 23 than the diameter of the large 0.5cm of diameter of the second carry-over pinch rolls 22, the 4th carry-over pinch rolls 24 than the large 0.5cm of diameter of the first carry-over pinch rolls 21, the diameter of the 3rd carry-over pinch rolls 23.
The reinforcing bar 5 becoming tentatively straight enters the first carry-over pinch rolls 21, enter the second carry-over pinch rolls 22 subsequently, the diameter of the second carry-over pinch rolls 22 0.5cm larger than the diameter of the first carry-over pinch rolls 21 because the first carry-over pinch rolls 21 are equal with the angular speed of the second carry-over pinch rolls 22, namely the second carry-over pinch rolls 22 are larger with the linear velocity of reinforcing bar 5 contact position than the first carry-over pinch rolls 21 with the linear velocity of reinforcing bar 5 contact position, therefore a stretching action can be produced to reinforcing bar 5, certain stretching is produced at the chien shih reinforcing bar 5 of the first carry-over pinch rolls 21 and the second carry-over pinch rolls 22, in drawing process, the reinforcing bar 5 of this section also can become more straight simultaneously, in like manner between the second carry-over pinch rolls 22 and the 3rd carry-over pinch rolls 23, can produce identical stretching and align effect equally between 3rd carry-over pinch rolls 23 with the 4th carry-over pinch rolls 24, the superposition of this stretching and aligning effect, finally make the reinforcing bar 5 after leaving stretching-straightening device 2 become very straight and be stretched and eliminate prestressing force, meet the needs of construction, concrete extensibility can be adjusted by the diameter arranging each carry-over pinch rolls, make it the extensibility conformed with the regulations.
Shearing device is that cutting knife adopts vertical cut-out mode to complete cut-out reinforcing bar, cutting knife can adopt cam mechanism also can adopt frame for movement gyration being converted to linear reciprocating motion generally adopted in the prior aries such as rack-and-pinion, thus realize cutting off reinforcing bar 5 according to the length of setting, it will not go into details herein.
Above content is in conjunction with concrete preferred embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For the those of ordinary skill belonging to the present invention, under the prerequisite not departing from this present invention thinking, simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
