Embodiment 1

[0021] In order to overcome the problems of large errors and serious scratches on the bar in the existing device, the present invention provides a device such as figure 1 As shown in the two-roller leveling machine overrunning feeding device, the present invention has small error, reduces the possibility of bar scratches, and ensures the surface smoothness of the finished bar to the greatest extent.

[0022] The two-roller straightening machine surpasses the feeding device, including the front pinch frame 1, and the upper and lower sides of the front pinch frame 1 are respectively provided with an upper roller 2 and a lower roller 4, and one end of the lower roller 4 is connected with a driving device 6 , the driving device 6 and the lower roller 4 are connected through an overrunning clutch 7; the front pinch frame 1 is provided with a main machine straightening roller 8 in the feeding direction, and the driving device 6 is electrically connected to a frequency conversion cont...

Embodiment 2

[0025] Based on the basis of embodiment 1, such as figure 2 As shown, the overrunning clutch 7 in this embodiment is a roller type overrunning clutch, and the overrunning clutch 7 includes an inner ring 12 and an outer ring 13, and several belt rollers 11 are arranged between the inner ring 12 and the outer ring 13, The roller 11 is tightly connected with the push column 10 arranged on the inner ring 12 , and the spring 9 is arranged on the push column 10 .

[0026] When the angular velocity of the outer ring 13 is less than the angular velocity of the inner ring 12, the inner ring 12 and the outer ring 13 will run synchronously through the roller 11; when the angular velocity of the outer ring 13 is greater than the angular velocity of the inner ring 12, the inner and outer rings will be free Sliding, only a very small rotational friction torque exists.

[0027] The driving device 6 and the inner ring 12 of the overrunning clutch 7 are connected by bolts, and the lower roll...

Embodiment 3

[0030] Based on the above two embodiments, in this embodiment, the main machine straightening roller 8 is flush with the front pinch frame 1 . When the workpiece 3 clamped between the upper roller 2 and the lower roller 4 is sent into the straightening roller 8 of the main machine, there will be no sawing in position.

[0031] The frequency conversion control system 5 controls the speed of the driving device 6 to match the speed of the driving device of the main machine, and the speed of the driving device 6 is lower than the speed of the straightening roller 8 of the main machine.

[0032] When the bar material bites into the straightening roller 8 of the main machine and the upper roller 2 is not opened at the same time, the head of the workpiece 3 is bitten into the straightening roller 8 of the main machine and the tail is still in the front pinch roller, due to the speed of the straightening roller 8 of the main machine Slightly higher than the speed of the upper roller 2...

Abstract

The invention provides an overrunning type feeding device for a two-roller straightening machine. The overrunning type feeding device comprises a front clamping rack. An upper roller and a lower roller are arranged at the upper portion and the lower portion in the front clamping rack respectively. One end of the lower roller is connected with a driving device. The driving device and the lower roller are connected through an overrunning clutch. Main machine straightening rollers are arranged in the feeding direction of the front clamping rack. The driving device is electrically connected with a frequency conversion control system. The main machine straightening rollers are electrically connected with the frequency conversion control system. The overrunning clutch is an intersecting shaft straight-tooth bevel gear. The main machine straightening rollers are connected with a main machine driving device. The frequency conversion control system controls the speed of the driving device to be matched with the speed of the main machine driving device. The speed of the driving device is lower than that of the main machine straightening roller. The main machine driving device and the driving device are both oil cylinders. An overrunning feeding system is utilized, and the surface smoothness of straightened bars can be guaranteed under the condition that the speed difference exists between a main machine and a feeding mechanism.

Description

technical field [0001] The invention relates to an overtaking type feeding device of a two-roller straightening machine. Background technique [0002] As a precision straightening equipment, the two-roller straightening machine is an important part of the bar finishing line. It is mostly used in conjunction with the peeling machine to straighten and roll the bar after peeling to improve the quality of the finished bar. straightness and surface finish. Due to the unique straightening principle of the two-roll leveler, the use of multi-roll leveler roller feeding will often cause the bar to bite in smoothly, so the existing two-roll leveler is generally passed by the front feeding mechanism. The bar is fed into the main machine of the straightening machine in the form of pinching the rollers. When feeding, send the head of the bar into the pinch range of the feeding mechanism, drive the upper and lower pinch rollers to open and close through the oil cylinder, and then start ...
