Description

Technical Field

[0001] This utility model belongs to the technical field of metal wire production equipment, specifically relating to a stainless steel spring wire I-beam reel take-up machine. Background Technology

[0002] The existing winding method is generally to wind up the wire in separate rolls, with a maximum of 50 kg per roll. The weight of each roll is too small, requiring workers to frequently reload, which cannot guarantee the continuity of work. In addition, because it is packaged separately, additional tooling is needed to fix the wire and perform the winding work. However, the packaging of each piece of wire is different, and the winding tooling needs to be adjusted at any time, which increases the workload.

[0003] To address the shortcomings of take-up reels, H-beam reels are commonly used. They can handle up to four times the weight of take-up reels compared to take-up reels, reducing the frequency of reel changes. Furthermore, with H-beam reel take-up, the spring wire packaging is secured, and the unloading fixture is fixed, making operation simple and convenient. However, the H-beam reels of traditional take-up machines do not move left and right; instead, the wire guide moves them, resulting in significant and uncontrollable linear variations. When using a traditional H-beam reel take-up machine to take up stainless steel spring wire, the spring wire adheres to the inner ring of the H-beam reel. The tension increases as the wire thickness increases, causing inconsistencies in linearity between the smallest and outermost coils, leading to product defects. In other words, while traditional take-up machines are suitable for products with low linearity requirements, they are unsuitable for products like stainless steel spring wire with high linearity requirements. Summary of the Invention

[0004] The purpose of this invention is to provide a stainless steel spring wire take-up reel that can reduce the tension effect of traditional take-up reel machines, reduce linear changes, and make the internal and external linearity of take-up reel consistent.

[0017] Wherein: 1 is the base, 2 is the lead screw, 3 is the first servo motor, 4 is the fixed plate, 5 is the I-beam wheel, 6 is the rotary drive mechanism, 7 is the constant tension device, 7.1 is the first tension wheel, 7.2 is the tension arm, 7.3 is the cylinder, 7.4 is the square tube frame, 7.5 is the second tension wheel, and 8 is the stainless steel spring wire. Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 The diagram shown is a structural schematic of the stainless steel spring wire reel take-up machine in this embodiment.

[0020] A stainless steel spring wire take-up reel includes a base 1, a lead screw 2 at the lower end of the base 1, one end of the lead screw 2 being fixedly connected to the output end of a first servo motor 3, two symmetrically arranged fixed plates 4 at the upper end of the base 1, and an I-beam 5 clamped between the inner sides of the two fixed plates 4. The I-beam 5 is connected to the output end of a rotary drive mechanism 6 via a wheel axle. The rotary drive mechanism 6 is a rotary motor. The stainless steel spring wire 8 taken up on the I-beam 5 originates from a constant tension device 7.

[0021] The I-beam wheel 5 has top cones at both ends, and the top cones at both ends are clamped to the inner side of the fixed vertical plate 4 by a pin cylinder; the top cones at both ends are connected by a wheel axle, and each top cone has a conical hole and is coaxial.

[0022] like Figure 2 The diagram shows the structure of the constant tension device of this utility model.

[0023] The constant tension device 7 includes a first tension wheel 7.1, which is mounted on one end of a tension arm 7.2 via a bearing. The other end of the tension arm 7.2 is rotatably connected to the piston rod end of a cylinder 7.3, which is mounted on a square tube frame 7.4. The constant tension device 7 also includes a second tension wheel 7.5, which is fixed to the square tube frame 7.4 via a bearing.

[0024] The second tension wheel 7.5 is located above the first tension wheel 7.1. The first tension wheel 7.1 and the second tension wheel 7.5 are each connected to a second servo motor. The cylinder 7.3 is vertically positioned and equipped with a displacement sensor. The displacement sensor, the second servo motor, and the cylinder 7.3 are all connected to a PLC controller. The displacement sensor detects changes in the piston displacement of the cylinder 7.3 and transmits this information to the PLC controller. A preset program within the PLC controller then controls the rotation speed of the second servo motor to increase or decrease, ensuring constant tension during the winding process.

[0025] In practical applications, the winding process of a stainless steel spring wire reel winding machine is as follows: After being drawn by the wire drawing machine, the stainless steel spring wire 8 passes sequentially through the second tension wheel 7.5, the first tension wheel 7.1, and the second tension wheel 7.5 in the constant tension device 7 before being wound onto the I-beam 5. During the winding process, when the tension of the stainless steel spring wire 8 changes, the cylinder 7.3, displacement sensor, second servo motor, and PLC controller work together to adjust the tension and keep it constant. This is because the stainless steel spring wire 8 is wound onto the left-right moving winding I-beam 5 by the constant tension device 7 (where the rotary motor drives the wheel shaft, causing the I-beam 5 to rotate and wind the wire, and the servo motor 3 drives the lead screw 2, causing the I-beam 5 on the base 1 to move left and right). This achieves a fixed wire output direction while the winding I-beam 5 moves, which to some extent reduces the linear variation of the spring wire.

[0026] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
