Abstract

The utility model is a compact active cold rolling ribbed reinforcing bar mill which can make two Y-shaped rollers work at the same time. In addition, the quality of the reinforcing bar processed by the utility model is stable. The gap between the roller and a cone gear is easy to be adjusted by the utility model. The utility model comprises an electric motor, a moving axis, a gear and a roller. The electric motor engages with two gears through the gear on a main transmission shaft. The gear and the shaft on which the gear is arranged drive a main drive shaft rotate. A supporting main drive shaft or a driven shaft is combined with a shaft block as one. The shaft block is connected with a fixed stander by a dump rail. The shaft block can be adjusted by an adjusting screw mandrel that is connected with the shaft block. The utility model is especially suitable for processing the cold rolling ribbed reinforcing bar.

Description

The active cold rolled reinforcing steel bar with ribs milling train of compact

Technical field: the utility model relates to the reinforcing bar processing technique field, and exactly it is the active cold rolled reinforcing steel bar with ribs milling train of a kind of compact.This milling train is initiatively rolling, and two groups of Y type symmetric arrangement rolls are finished technical process of tube reducing indentation by a Motor Drive smoothly to guarantee that two groups of rolls are synchronously rolling, and adjustable center distance saves very for a short time, realizes no twist rolling.

Background technology: reinforcing bar is the indispensable steel in field such as architectural engineering, and the quality of its quality is very big to the quality influence of architectural engineering.Existing active Y type cold rolled reinforcing steel bar with ribs milling train, also adopt two groups of rolls for finishing technical process of tube reducing indentation, but these two groups of rolls are driven by two motors respectively, and owing to structural reason distance must be far away, be unfavorable for rolling synchronously like this, reinforcing bar is piled up between two groups of rolls and influenced and produce or produce the stability that excessive drawing reduces steel bar quality, reinforcing bar is twisted between two groups of rolls influences presentation quality.It is fully closed also having the existing exactly initiatively frame of milling train back-up roll, rigidity is fine, but manufacturing and processing and maintenance are all very difficult, and roll is supported separately by two bearing blocks that separate with dummy roll, influence the stability of the reinforcing bar quality of production because of poor rigidity, it is also relatively more difficult to make processing and maintenance, and the gap is also unadjustable between the conical gear of roll and dummy roll, is unfavorable for the adjustment in the production process.Existing besides active milling train is because complex structure, processing difficulties, and the device fabrication cost is also bigger.

Summary of the invention: the utility model provides the active cold rolled reinforcing steel bar with ribs milling train of a kind of compact, and it adopts a motor-driven, helps rollingly synchronously, and quality is better.It comprises motor, belt pulley, belt, power transmission shaft, gear, light circle roll and ragged roll etc., it is characterized in that: mesh by the gear on the final drive shaft (2) and two gears (3), (4) with a motor (1), gear (3) and (4) place axle drive driving shaft (6) and (17) and rotate respectively by export-oriented shaft joint (5) and (16).The bearing block (21) of supporting driving shaft (6), (17) or driven axle (28), (29) is an one, and bearing block (21) is connected with fixed frame (26) by slide rail (22), and can regulate by the adjusting screw mandrel (23) that is connected on the bearing block (21).Two groups of rolls are loaded on the inboard of fixed frame (26) symmetrically, can move by regulating screw mandrel (24), move but telephone-moving frame (25) prolongs the roll work center line.The utility model has the advantages that: reinforcing bar is difficult for producing at two groups of rolls to be piled up and influence production, perhaps produces excessively to draw and dials, and reduces quality of stability.And only use a motor-driven, can realize synchronous working.Two groups of roll centre-to-centre spacing can be regulated very closely, can produce arranged crosswise, and reinforcing bar is difficult for twisting, and presentation quality is better.Each roll supports with a movable axle bearing, thereby realizes the adjustment in gap between roll and the conical gear.

The specific embodiment:

Embodiment:

From accompanying drawing 1, can see, the utility model drives the gear 3 and the gear 4 that are meshed with it by motor 1 driven wheel 2 and rotates synchronously, gear 3 drives driving shaft 6 by Hooks coupling universal coupling 5 and rotates, a light circle roll 7 and two conical gears 8,9 are connected on the driving shaft 1, these two conical gears rotate simultaneously by driving two driven axles 14,15 that single light circle roll 12,13 is housed with its conical gear that meshes respectively 10,11 again, finish reinforcing bar tube reducing operation.Equally, gear 4 drives driving shaft 17 by Hooks coupling universal coupling 16 and rotates, and drives driven shaft 28,29 by conical gear again and rotates, and finishes reinforcing bar indentation operation thereby 3 ragged rolls 18,19,20 are rotated simultaneously.Two groups of Y type roll synchronous workings have so just been realized.

From Fig. 1 and Fig. 2, can also see, support driving shaft or driven axle bearing block 21 are one, so just increased support stiffness, also made things convenient for the processing of two dead eyes, but bearing block 21 is connected with telephone-moving frame 25 by slide rail 22 simultaneously, can move along direction by regulating leading screw 23, to adjust between the roll gap between the conical gear with axis normal.

From Fig. 2, can also see, two groups of rolls are fixed in the inboard of two relative frames respectively symmetrically, but allow telephone-moving frame 25 move along the roll work center line by regulating leading screw 24, reduce and fixed frame 26 between distance, can make two groups of roll centre-to-centre spacing very little, roll intersects, thereby guarantees that reinforcing bar does not twist when light is justified roll to ragged roll, realizes no twist rolling.

All above these mechanisms all are combined on the support 27 compactly, have made things convenient for and have installed and produce.
