Abstract

Disclosed is a novel steel bar bender. The novel steel bar bender comprises a machining platform, a motor and a speed reducing mechanism, and is characterized by further comprising a steel bar channel formed in the machining platform, and a runner group. The steel bar channel is arranged in a J shape. The runner group comprises a guiding-in wheel, a pair of guiding wheels and two pressing wheels. The pair of guiding wheels comprises the upper wheel and the lower wheel. The guiding-in wheel, the upper wheel and the two pressing wheels rotate at the same speed in the anti-clockwise direction, the lower wheel rotates in the clockwise direction, and the rotating speed of the lower wheel is equal to that of the upper wheel. An improvement lies in that the longitudinal positions of the two pressing wheels are adjustable. By means of the novel steel bar bender, one-time forming can be achieved, the quality is stable and reliable, manual radian adjustment is not needed, the labor cost can be reduced by 50%, and the production efficiency can be improved by two times or above.

Description

Novel reinforcing steel bar bending machine

Technical field

The present invention relates to a kind of building machinery, especially a kind of angle-bender.

Background technology

The angle-bender of prior art, uses rotary-disk type structure more, is suitable to bend right angle.Bridge tunnel construction is needed The making of the arch steel of the big radian wanted, manually adjusts into the radian of requirement again after can only being bent into multiple straightway, its matter Amount instability, error is big.The Chinese patent of Patent No. 201420498498.4 discloses a kind of arc-shaped reinforcing steel bar bending machine, and this is special Profit uses rotating disk to add the structure of arc backup plate, is only suitable to the processing of small size arch steel, is unsuitable for processing large scale arch steel, The arch steel of multiple radian can not be processed.A kind of bar bending being suitable to process large-sized arch steel is needed in production Machine.

Summary of the invention

The problem to be solved in the present invention is to provide a kind of Novel reinforcing steel bar bending machine.

The present invention adopts the following technical scheme that and includes processing platform, motor, reducing gear, also includes being located at processing platform On reinforcing bar passage and a runner group, described reinforcing bar passage become J-shaped layout, described runner group include one introduce wheel, a pair Directive wheel and two pinch rollers, the pair of directive wheel includes taking turns and lower whorl, described introducing wheel, on take turns and two pinch rollers are counterclockwise The synchronized rotation in direction, described lower whorl is rotated clockwise, and lower whorl is identical with upper wheel speed.Its principle is: reinforcing bar is by introducing wheel Side enters reinforcing bar passage, and end is inserted in a pair directive wheel, and owing to each runner of runner group is all rotating, reinforcing bar is directed Right lateral, under the continuous action of two pinch rollers, reinforcing bar is bent molding.

A kind of improvement is that described pinch roller is assemblied on axle bed by rotating shaft, and described axle bed is the adjustable activity of lengthwise position Formula structure.Owing to the lengthwise position of pinch roller is adjustable, may be adapted to process the arch steel of multiple radian.

Another kind of improvement is that described movable structure includes that screw mechanism, described screw mechanism are connected with axle bed.Use The position of screw mechanism two pinch rollers of regulation, its Stability Analysis of Structures is reliable.

Also having one to improve is that described pinch roller is produced by the second gear in the first gear driven rotating shaft and rotates, described The position adjustment path of axle bed is an arc, and described arc is positioned on the concentric circular of the first gear, described screw mechanism It is connected with axle bed by a pin joint.Using this structure, in axle bed moving process, the first gear and the second gear can Remain engagement.

Present invention have the advantage that 1, its simple in construction, it is easy to practice and extension.2, arch steel can one-shot forming, batch The amount quality of production is reliable and stable, and error is little.3, alleviate the labor intensity of operator, save labor.The steel of former rotary-disk type structure Muscle bending machine produces arch steel, needs four people's operation (start shooting 1 people, feeding 1 people, splicing two people), and this device only needs two people's operations (start shooting 1 people, feeding and splicing 1 people), can save labour cost 50%, be further without manpower and adjust radian.4, production efficiency can improve 2 More than Bei.

In figure: reinforcing bar passage 1, runner group 2, introducing wheel 3, directive wheel 4, pinch roller 5, screw mechanism 6, the first gear 7, second Gear 8, pin joint 9, on take turns 41 and lower whorl 42.

Detailed description of the invention

As shown in Figure 1 to Figure 3, an embodiment of the present invention includes processing platform, motor, reducing gear, also includes being located at Reinforcing bar passage 1 on processing platform and a runner group 2, described reinforcing bar passage 1 becomes J-shaped layout, described runner group 2 to include one Introducing wheel 3, a pair directive wheel 4 and two pinch rollers 5, the pair of directive wheel 4 includes taking turns 41 and lower whorl 42, described introducing wheel 3, On take turns 41 and the counterclockwise synchronized rotations of two pinch rollers 5, described lower whorl 42 is rotated clockwise, lower whorl 42 with on take turns 41 turns Speed is identical.Its principle is: reinforcing bar is entered reinforcing bar passage 1 by introducing wheel 3 side, and end is inserted in a pair directive wheel 4, due to runner Each runner of group 2 is all rotating, and the directed right lateral of reinforcing bar, under the continuous action of two pinch rollers 5, reinforcing bar is bent molding.

A kind of improvement is that described pinch roller 5 is assemblied on axle bed by rotating shaft, and described axle bed is the adjustable activity of lengthwise position Formula structure.Owing to the lengthwise position of pinch roller 5 is adjustable, may be adapted to process the arch steel of multiple radian.

As it is shown on figure 3, another kind of improvement is that described movable structure includes screw mechanism 6, described screw mechanism 6 and axle Seat is connected.Using the position of screw mechanism two pinch rollers 5 of regulation, its Stability Analysis of Structures is reliable.

As it is shown on figure 3, also having one to improve is that described pinch roller 5 is driven the second gear 8 in rotating shaft to produce by the first gear 7 Raw rotation, the position adjustment path of described axle bed is an arc, and described arc is positioned on the concentric circular of the first gear 7, Described screw mechanism 6 is connected with axle bed by a pin joint 9.Use this structure, in axle bed moving process, the first tooth Wheel 7 and the second gear 8 can remain engagement.Described axle bed can be arranged on an arc-shaped slide rail motion.

The present invention is not limited to the concrete structure of above-described embodiment, and the equivalent transformation of other homogeneous structure each falls within the present invention Protection domain within.
