Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology for copper alloy strip, specifically a heat treatment production line for copper alloy strip with tension adjustment function. Background Technology

[0002] Copper alloy strip is a high-performance strip material made by adding elements such as zinc, tin, nickel, and aluminum to copper as the base. It has comprehensive advantages such as electrical conductivity, thermal conductivity, corrosion resistance, and machinability. At present, it has been widely used in the fields of electronics, electrical appliances, power lighting, and machinery manufacturing.

[0003] During the production process, copper alloy strip needs to undergo annealing treatment on a heat treatment production line. The purpose of this treatment is to eliminate work hardening and allow the alloy to recrystallize into a refined grain structure, thereby obtaining good plasticity and low deformation resistance.

[0004] However, copper strips are shipped in rolls with significant internal tension. When the copper strip moves on the guide rollers in the heat treatment production line, the guide rollers need to overcome their own tension to guide and transport it. When a roll of copper strip is used up, due to the lack of effective blocking measures above the guide rollers, the copper strip ends will lose their force after leaving one of the guide rollers. Therefore, the ends of the copper strip can easily bounce off, causing a certain danger.

[0005] To address these issues, this invention provides a copper alloy strip heat treatment production line with tension adjustment function. Utility Model Content

[0109] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0110] Working principle: First, the copper strip is fed to the uncoiler 2 by the flat feeding trolley 1, and the copper strip is released by the uncoiler 2. Then, the copper strip is guided by the first guide roller 3 and passes through the inlet side cross-cutting machine 4 for head and tail cutting. After being processed by the inlet side cross-cutting machine 4, the copper strip passes the bottom end of the guide roller 16 and passes around the top end of the reversing roller 17. Then, it passes around the bottom end of the tension adjusting roller 23 and is introduced into the tension measuring device body 6. After being processed by the tension measuring device body 6, the copper strip is sent to the annealing furnace 7 for annealing. After being annealed in the annealing furnace 7, the copper strip is received by the correction roller 8 and then sent to the outlet side cross-cutting machine 10 under the support of the tension adjusting roller 23, the reversing roller 17, the guide roller 16 and the second guide roller 9. After being processed by the outlet side cross-cutting machine 10, it is wound up by the winding machine 12.

[0111] Before the tension adjusting roller 23 is used, the electric push rod 24 can be started, thereby using the push frame 21 to push the tension adjusting roller 23 for vertical adjustment. Since the copper strip is located on the guide roller 16, the reversing roller 17 and the tension adjusting roller 23, the tension of the copper strip can be adjusted when the tension adjusting roller 23 is vertically displaced.

[0112] After the copper strip passes over the reversing roller 17, the hydraulic rod 40 is activated, causing its output end to push the eccentric adjustment plate 41. Since the eccentric adjustment plate 41 is supported by the central shaft 27, the rotation of the central shaft 27 can drive the pressure roller 30 to approach the reversing roller 17, so as to limit the copper strip between the reversing roller 17 and the pressure roller 30.

[0113] When the pressure roller 30 is severely worn, rotate the transmission screw 38. With the transmission screw 38 connected to the displacement seat 39, the displacement seat 39 can be vertically displaced along the transmission screw 38. In conjunction with the connection between the displacement seat 39 and the through groove 36, when the displacement seat 39 is vertically displaced, it can simultaneously pull the eccentric plate 34, causing the eccentric plate 34 to rotate under the support of the linkage rod 33. Since the linkage plate 35 is connected between the eccentric plate 34 and the positioning plate 32, when the eccentric plate 34 rotates, it can pull the positioning plate 32 with the help of the linkage plate 35, causing the positioning plate 32 to flip under the support of the extension ear 31, thereby removing the obstruction to the pressure roller 30. Then the pressure roller 30 can be removed and replaced.
