Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The invention relates to a rotary blanking device for reinforcing steel bars, which has the following structure: the steel bar conveying device comprises a left main support 1, a right main support 1, a hydraulic oil cylinder 2, a hollow rotating shaft 3, a steel bar conveying disc 4, a bearing with a shell 5, an oil cylinder support 6, a driving unit 7, a chain 8 and a driving unit support 9; oil cylinder supports 6 are fixed on the two main supports 1, and the oil cylinder supports 6 are connected with the hydraulic oil cylinder 2; a hollow rotating shaft 3 is arranged between the hydraulic oil cylinders 2 on the two sides, a radial bearing is embedded in the hollow rotating shaft 3, the hollow rotating shaft 3 is wrapped on the hydraulic oil cylinders 2, and a steel bar conveying disc 4, a chain wheel 11 and a shell bearing 5 are sleeved outside the hollow rotating shaft 3; the driving unit 7 is connected with a chain wheel 11 on the hollow rotating shaft 3 through a chain 8, and a driving unit bracket 9 is connected with the outer side of the belt shell bearing 5 and the base of the driving unit 7; the bottom of the driving unit bracket 9 is provided with a pulley 10.

As an improvement, the main support 1 is machined by a rectangular pipe or square steel, is symmetrically arranged at two sides of the device and is a main bearing structure of the device. The hydraulic oil cylinder 2 is connected with the oil cylinder supports 6 at the two sides and is positioned on the main bracket 1. Two sides of the hydraulic oil cylinder 2 are connected with an oil cylinder support 6 by adopting an earring or a flange, and a hollow rotating shaft 3, a steel bar conveying disc 4 and a bearing with a shell 5 are fixed on an outer cylinder of the hydraulic oil cylinder 2.

The hollow rotating shaft 3 is internally embedded with a radial bearing and is wrapped on the hydraulic oil cylinder 2, and the shaft is externally sleeved with a steel bar conveying disc 4, a chain wheel and a shell bearing 5. The driving unit 7 is composed of a motor, a speed reducer and the like, and is connected with a chain wheel 11 on the hollow rotating shaft 3 through a chain 8 to drive the hollow rotating shaft 3 to rotate clockwise. The top surface of the driving unit 7 should be lower than the bottom surface of the reinforcing bar transfer plate 4. One end of a driving unit bracket 9 is connected with the shell of the bearing with shell 5, the other end is connected with a connecting shaft of a driving unit 7, and a pulley 10 is arranged at the bottom of the driving unit 7, so that the driving unit 7 can move left and right along with the extension of the hydraulic oil cylinder 2.

During the specific use, at first start hydraulic control system, according to the 2 strokes of required offset adjustment hydraulic cylinder, treat that hydraulic cylinder 2 stretches out and draws back and start drive unit 7 after targetting in place, make cavity rotation axis 3 drive reinforcing bar transfer dish 4 and do clockwise rotation to the reinforcing bar that will fall on reinforcing bar transfer dish 4 makes the reinforcing bar roll downwards along the parabola through rotational acceleration, falls into the reinforcing bar draw-in groove that the below set up in advance, and to this, first reinforcing bar is carried and is accomplished. And then adjusting the stroke of the hydraulic oil cylinder 2 to enable the steel bar conveying disc 4 to deviate in the opposite direction, repeating the steps, and completing the conveying of a second steel bar to enable the ends of the two steel bars to reach the required offset distance.

And repeating the steps (the driving unit 7 is in an operating state after being started for the first time and before being finished) until the planned number of steel bars are completely blanked and placed. The steel bar conveying device is reasonable in structural design, achieves mechanical and automatic operation of steel bar conveying, can reduce labor cost, improves construction efficiency, and greatly reduces manual operation strength.
