Description

Technical Field

[0001] This utility model relates to the technical field of tension fine-tuning mechanisms, specifically a tension fine-tuning mechanism for bar stock after cutting. Background Technology

[0002] During the rolling of special steel, the temperature of the final rolling needs to be significantly reduced, resulting in a large temperature difference between the head and other parts, which generates a large tension.

[0003] Traditional tension fine-tuning mechanisms often integrate pressure sensors and controllers into a compact module for real-time adjustment of the guide roller position. While this method is intelligent, it is slow to respond to instantaneous fluctuations in tension, resulting in unstable product quality. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] The tension fine-tuning mechanism after bar cutting includes a guiding mechanism and an adjusting mechanism. The guiding mechanism includes a crossbeam, a guide sleeve sleeved on the outside of the crossbeam, two piston lifting rods respectively fixed to both ends of the crossbeam, a rod sleeve slidably sleeved on the outside of the piston lifting rods, an air pipe fixed to one side of the rod sleeve, and a rubber rod interference-fitted with the air pipe. The adjusting mechanism includes a pull rope fixed between the crossbeam and the rubber rod, a large roller frame attached to the bottom of the pull rope and sleeved on the outside of the air pipe, and a small roller frame attached to the top of the pull rope and fixed to the top of the air pipe. The air pipe has an opening suitable for the movement of the pull rope.

[0007] By adopting the above technical solution, after the bar passes through the guide sleeve, the undulation of the bar is transmitted to the two piston lifting rods through the crossbeam. Then, the rod sleeve provides guidance and stable support. When the piston lifting rod is lowered under force, it will squeeze the rubber rod in the air chamber and then slide outward. At this time, according to the principle of air pressure, the pull rope, guided by the large roller frame and the small roller frame, quickly pulls the rubber rod back to the initial position, thereby returning the crossbeam and guide sleeve to the initial height. This tension fine-tuning structure is responsive and timely, which greatly ensures the stability of product quality.

[0008] In a preferred embodiment, the present invention can be further configured such that: an air chamber suitable for the lifting and lowering of the piston rod is provided inside the sleeve, and the inside of the air pipe is connected to the inside of the air chamber.

[0009] In a preferred embodiment, the present invention can be further configured such that: a slot suitable for inserting an air tube is provided on one side of the rod sleeve, and the air tube is made of alloy steel.

[0010] In a preferred embodiment, the present invention can be further configured such that the sleeve is frustum-shaped and is made of metal.

[0011] In a preferred embodiment, the present invention can be further configured such that the large roller is mounted between the rod sleeve and the small roller frame, and both the large roller frame and the small roller frame are made of plastic material.

[0012] In a preferred embodiment, the present invention can be further configured such that the pull rope is made of multiple steel wires bound together, and the diameter of the pull rope is smaller than the width of the opening.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] In this invention, after the rod passes through the guide sleeve, the undulation of the rod is transmitted to the two piston lifting rods through the crossbeam. The rod sleeve then provides guidance and stable support. When the piston lifting rod descends under force, it squeezes the rubber rod inside the air chamber, causing the rubber rod to slide outward. At this point, based on the principle of air pressure, the pull rope, guided by the large and small roller frames, quickly pulls the rubber rod back to its initial position, thereby returning the crossbeam and guide sleeve to their initial height. This tension fine-tuning structure is highly responsive and timely, greatly ensuring the stability of product quality. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0024] The tension fine-tuning mechanism after bar cutting provided by some embodiments of this utility model is described below with reference to the accompanying drawings.

[0025] Example 1:

[0026] Combination Figure 1-4 As shown, the tension fine-tuning mechanism after bar cutting provided by this utility model includes a guiding mechanism 100 and an adjusting mechanism 200. The guiding mechanism 100 includes a crossbeam 110, a guide sleeve 120 sleeved on the outside of the crossbeam 110, two piston lifting rods 130 respectively fixed to both ends of the crossbeam 110, a rod sleeve 140 slidably sleeved on the outside of the piston lifting rods 130, an air pipe 150 fixed to one side of the rod sleeve 140, and a rubber rod 160 interference-fitted with the air pipe 150.

[0027] The adjustment mechanism 200 includes a pull rope 210 fixed between the crossbeam 110 and the rubber rod 160, a large roller frame 220 attached to the bottom of the pull rope 210 and sleeved on the outside of the air tube 150, and a small roller frame 230 attached to the top of the pull rope 210 and fixed to the top of the air tube 150. The air tube 150 has an opening suitable for the movement of the pull rope 210.

[0028] Furthermore, the sleeve 140 has an air chamber inside that is suitable for the piston lifting rod 130 to rise and fall, and the air pipe 150 is connected to the air chamber. The air chamber is provided to provide conditions for the piston lifting rod 130 to rise and fall.

[0029] Furthermore, a slot suitable for inserting the air tube 150 is provided on one side of the sleeve 140. The air tube 150 is made of alloy steel and the slot provides conditions for successful installation of the air tube 150.

[0030] Furthermore, the pull rope 210 is made of multiple steel wires bundled together, and the diameter of the pull rope 210 is smaller than the width of the opening. The manufacturing method of the pull rope 210 can reduce the probability of the pull rope 210 breaking.

[0031] Example 2:

[0032] Combination Figure 1-4 As shown, based on Embodiment 1, the rod sleeve 140 is configured as a frustum shape and is made of metal material. Using metal raw materials to make the rod sleeve 140 increases its self-weight and ensures that it can stably support the crossbeam 110.

[0033] Example 3:

[0034] Combination Figure 2 and Figure 4 As shown, in the above embodiment, the large roller frame 220 is disposed between the rod sleeve 140 and the small roller frame 230. Both the large roller frame 220 and the small roller frame 230 are made of plastic material. Using plastic material to make the large roller frame 220 and the small roller frame 230 can reduce the wear of the pull rope 210.

[0035] The working principle and usage process of this utility model are as follows: When this device is put into actual use, after the rod passes through the guide sleeve 120, the undulation of the rod will be transmitted to the two piston lifting rods 130 through the crossbeam 110. Then, the rod sleeve 140 provides guidance and stable support. When the piston lifting rod 130 is lowered under force, it will squeeze the rubber rod 160 in the air chamber. Then, the rubber rod 160 slides outward. At this time, according to the principle of air pressure, the pull rope 210, guided by the large roller frame 220 and the small roller frame 230, quickly pulls the rubber rod 160 back to the initial position, thereby making the crossbeam 110 and the guide sleeve 120 return to the initial height. This tension fine-tuning structure is sensitive and timely in intervention, which greatly ensures the stability of product quality.
