Description

Technical Field

[0001] The utility model relates to the technical field of crescent rib anchor rod processing, in particular to a crescent rib anchor rod looper device. Background Art

[0002] In the metallurgical industry, in the production of bar steel rolling, the bar production line is equipped with a looper between the rolling mills to meet the process requirements. The looper is used to detect and adjust the speed relationship between adjacent racks to achieve tension-free rolling. The looper makes the rolled piece bend between the two racks to form an arc, buffering the change in the flow rate between the racks, thereby eliminating the tension between the racks and improving the accuracy of the rolled piece size.

[0003] Crescent rib anchor steel bars are a type of bar material, mainly used in mine tunnels for support operations. They require cold processing during use and have very high requirements for dimensional accuracy. During the rolling process, the looper device ensures the accuracy of the steel size, so the use of the looper is more stringent.

[0004] The existing looping device has both flat rollers in its lifting rollers and guide rollers. The high-speed wire moves in an arc shape after being lifted by the lifting rollers, and then enters the guide rollers. During this period, the workpiece is prone to shaking, causing it to be thrown onto the side plates on the front and rear sides of the loop, which will scratch the surface of the workpiece and affect product quality. Utility Model Content

[0005] In order to overcome the defect that the rolled piece is prone to shaking in the prior art, the utility model provides a crescent rib anchor rod looper device.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a crescent rib anchor rod looper device, comprising a base, a looper is arranged on the base, a feed fixed roller assembly is arranged at the inlet end of the looper, a discharge fixed roller assembly is arranged at the outlet end of the looper, a looping roller is arranged in the middle position of the feed fixed roller assembly and the discharge fixed roller assembly, a feed guide plate is arranged on the left side of the feed fixed roller assembly, and a discharge guide roller is arranged on the right side of the discharge fixed roller assembly.

[0007] As a further improvement of the utility model, the feed fixed roller assembly and the discharge fixed roller assembly are symmetrically arranged.

[0008] As a further improvement of the utility model, the feed fixed roller assembly and the discharge fixed roller assembly both include an upper fixed roller and a lower fixed roller matched with the upper fixed roller.

[0009] As a further improvement of the utility model, a positioning cylinder capable of lifting the sleeve-lifting roller is provided at the lower part of the sleeve-lifting roller.

[0010] As a further improvement of the present invention, a feed guide roller matched with the feed guide plate is provided between the feed guide plate and the feed fixed roller assembly.

[0011] As a further improvement of the utility model, a discharging guide plate matched with the discharging guide roller is provided between the discharging guide roller and the sleeve-lifting roller.

[0012] Compared with the prior art, the utility model has the beneficial effects: in this scheme, the rolled piece enters the looping device, and the length of the looping parabola is determined by the feed fixed roller assembly and the discharge fixed roller assembly. The rolled piece enters the feed fixed roller assembly, and then is guided by the feed guide plate into the looping roller for looping parabola. The rolled piece after the looping parabola is guided by the discharge guide roller into the discharge fixed roller assembly. The feed fixed roller assembly and the discharge fixed roller assembly have a limiting effect on the rolled piece, which not only ensures that the rolled piece is always in the middle position in the looping device, improves the running stability of the rolled piece in the looping device, but also makes the looping height parabola of the rolled piece in the looping device perfect.

[0016] In order to make the technical solution and beneficial effects of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0017] Reference Figure 1 The utility model embodiment discloses a crescent rib anchor rod looper device, including a base 1, a looper 2 is arranged on the base 1, a feed fixed roller assembly 3 is arranged at the inlet end of the looper 2, a discharge fixed roller assembly 4 is arranged at the outlet end of the looper 2, a looper 6 is arranged in the middle position of the feed fixed roller assembly 3 and the discharge fixed roller assembly 4, a feed guide plate 8 is arranged on the left side of the feed fixed roller assembly 3, and a discharge guide roller 10 is arranged on the right side of the discharge fixed roller assembly 4.

[0018] The feed fixed roller assembly 3 and the discharge fixed roller assembly 4 are symmetrically arranged. The feed fixed roller assembly 3 and the discharge fixed roller assembly 4 both include an upper fixed roller and a lower fixed roller matched with the upper fixed roller.

[0019] When in use, the rolled piece 5 enters the looping device, and the length of the looping parabola is determined by the feed fixed roller assembly 3 and the discharge fixed roller assembly 4. The rolled piece 5 enters the feed fixed roller assembly 3, and is then guided by the feed guide plate 8 to enter the looping roller 6 for looping parabola. The rolled piece 5 after the looping parabola is guided by the discharge guide roller 10 to enter the discharge fixed roller assembly 4. The feed fixed roller assembly 3 and the discharge fixed roller assembly 4 have a limiting effect on the rolled piece, which not only ensures that the rolled piece 5 is always in the middle position in the looping device, but also improves the running stability of the rolled piece 5 in the looping device, and also makes the looping height parabola of the rolled piece 5 in the looping device perfect.
