Abstract
Description
Technical Field
[0001] This application relates to the field of buffer device technology, and more specifically, to a wire guide buffer device for a wire bundling machine. Background Technology
[0002] Wire rod baling machines are key equipment in high-speed wire rod mills. They mainly consist of a compaction cart, a wire feeding unit, a wire guide, and a baling head. Because the wire guide buffer device was originally designed as a hydraulic buffer, during the rolling of large-diameter, slowly cooling wire rods, the rapid rolling process and slow cooling of the wire rods resulted in higher temperatures during baling, reducing the service life of the hydraulic seals. This frequently led to leaks in the wire guide buffer device seals, causing oil contamination on the surface of the wire rod products and hindering further processing. This affected both product quality and production rhythm, and repairs were time-consuming and labor-intensive, failing to meet production needs. Utility Model Content
[0003] The purpose of this application is to provide a wire guide buffer device for a wire baling machine, which avoids product oil contamination caused by hydraulic leakage, improves product quality, and reduces maintenance costs.
[0004] This application provides a wire guide buffer device for a wire bundling machine, which adopts the following technical solution:
[0005] A wire guide buffer device for a wire baling machine includes a connecting seat, a cylinder, a pressure cap, and a buffer structure. The cylinder is mounted on the connecting seat and has a cylinder cover and two one-way valves. The buffer structure includes a rod, a piston, and a spring. The rod is movably inserted through the cylinder cover, and the cylinder cover and the piston are respectively located at both ends of the rod. The piston is located inside the cylinder. The spring is sleeved on the rod, and both ends of the spring abut against the pressure cap and the cylinder cover, respectively.
[0006] Preferably, the connecting seat has an internal thread, the cylinder has an external thread, and the connecting seat is threadedly connected to the cylinder.
[0007] Preferably, a nut is provided on the cylinder.
[0008] Preferably, a gasket is provided on the cylinder, and the gasket is located on the side of the connecting seat away from the nut.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:
[0013] This application features a simple structure, low manufacturing cost, and strong practicality. When an external force is applied to the gland, the spring is compressed, and the rod drives the piston to move inside the cylinder. The air inside the cylinder is discharged through one of the one-way valves and forms damping. Energy is absorbed and dissipated through the spring and air resistance, achieving the effect of shock absorption and vibration reduction, thereby extending the service life of the device and reducing maintenance costs.

[0024] Example
[0025] like Figure 1 As shown in the embodiment of this application, the wire guide buffer device of the wire baling machine includes a connecting seat 1, a cylinder 2, a pressure cover 3, and a buffer structure 4. The connecting seat 1 is installed on the wire baling machine, and the cylinder 2 is set on the connecting seat 1. The cylinder 2 is provided with a cylinder cover 5 and two one-way valves 6. The buffer structure 4 includes a rod 7, a piston 8, and a spring 9. The rod 7 is movably inserted through the cylinder cover 5. The cylinder cover 5 and the piston 8 are respectively set at both ends of the rod 7. The piston 8 is located inside the cylinder 2. The spring 9 is sleeved on the rod 7. The two ends of the spring 9 abut against the pressure cover 3 and the cylinder cover 5, respectively. In specific implementation, one of the one-way valves 6 has a large air inlet, which is used to quickly reset the pressure cover 3 under the action of the spring 9. The other one-way valve 6 has a small exhaust port, which is used to form damping when the piston 8 compresses the air and discharges, which can play a buffering role.
[0026] When an external force is applied to the pressure cap 3, the spring 9 is compressed, and the rod 7 drives the piston 8 to move inside the cylinder 2. The air inside the cylinder 2 is discharged through one of the one-way valves 6 and forms damping. Energy is absorbed and dissipated through the spring 9 and air resistance, achieving the effect of shock absorption and vibration reduction, thereby extending the service life of the device and reducing maintenance costs. After the force on the pressure cap 3 disappears, the spring 9 rebounds and applies force to the pressure cap 3. The rod 7 drives the piston 8 to move inside the cylinder 2, and the outside air enters the inside of the cylinder 2 through the other one-way valve 6.
[0027] In this embodiment, the connecting seat 1 has an internal thread and the cylinder 2 has an external thread. The connecting seat 1 and the cylinder 2 are threadedly connected, and the threaded connection facilitates the disassembly and assembly of the connecting seat 1 and the cylinder 2.
[0028] In this embodiment, a nut 10 is provided on the cylinder 2. The nut 10 is used to fasten the cylinder 2 and improve the stability of the cylinder 2.
[0029] In this embodiment, a gasket 11 is provided on the cylinder 2. The gasket 11 is located on the side of the connecting seat 1 away from the nut 10. The gasket 11 is placed between the connecting seat 1 and the wire baling machine. The distance between the connecting seat 1 and the wire baling machine can be adjusted by changing the number of gaskets 11.
[0030] In this embodiment, the pressure cap 3 is fixed to the rod body 7 by bolts 12, and the use of bolts 12 for fixing facilitates the disassembly of the pressure cap 3.
[0031] In this embodiment, the connector 1 is provided with a mounting hole 13. The mounting hole 13 facilitates the connection of the connector 1 to the wire packing machine, thereby facilitating the assembly and disassembly of the connector 1.
[0032] In this embodiment, a groove 14 is formed between the cylinder 2 and the cylinder head 5. One end of the spring 9 is located in the groove 14. The groove 14 limits the spring 9 and improves the performance of the spring 9.
[0033] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
