Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxygen-free copper molding and slicing production technology, and in particular to a batch molding and slicing production equipment for oxygen-free copper. Background Technology
[0002] Oxygen-free copper electrode sheets are indispensable as key conductive components in industrial products such as appliance connectors due to their excellent conductivity, oxidation resistance, and processing performance. Market demand is huge, typically requiring efficient, large-scale mass production. The current mainstream manufacturing process generally adopts a "press-saw" process: first, copper wire is pressed into the required specific cross-sectional shape (such as sheet or irregular shape) using a mold; then, a high-speed rotating metal saw blade is used to cut the continuously pressed copper material to a fixed length, thus obtaining individual electrode sheets. However, this traditional pressing and saw process has significant limitations: Difficult length adjustment: Changing the electrode sheet cutting length usually requires cumbersome adjustments to mechanical limits or tooling changes, resulting in poor flexibility and difficulty in quickly responding to production switching needs for different specifications. Poor cut quality: During rotary saw cutting, burrs, flash, or micro-deformation are easily generated at the copper material's cut edge, leading to poor cut smoothness. This not only affects the product's appearance and assembly accuracy but may also cause stress concentration or poor contact during use. Production efficiency bottleneck: The inherent physical characteristics of rotary saw cutting and the limitation of single-cut stroke make it difficult to significantly increase the production cycle time, becoming a key factor restricting production capacity. Severe tool wear and high costs: Although oxygen-free copper is soft, it is sticky. During high-speed sawing, copper shavings easily adhere to and accumulate on the saw teeth, causing the saw blade edges to quickly become dull and wear down. This not only requires frequent machine stops to replace the saw blade, increasing expensive tool costs, but also severely disrupts the continuous production process due to frequent replacement operations, reducing the overall efficiency of the equipment.
[0003] Therefore, developing a more advanced and reliable electrode cutting technology to overcome the above-mentioned defects is of urgent practical significance and significant economic value. Utility Model Content
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a batch pressing and slicing production equipment for oxygen-free copper.
[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a batch pressing and slicing production equipment for oxygen-free copper, including: a workbench, and a base, guide roller group, pressing mechanism and slicing mechanism disposed on the workbench;
[0006] The guide roller group includes several guide rollers for guiding oxygen-free copper wire into the machine base; the forming mechanism and the slicing mechanism are mounted on the machine base;
[0007] The forming mechanism includes a forming drive assembly and two forming rollers; the two forming rollers roll up and down and abut against each other, and the surfaces of the two forming roller assemblies are provided with a plurality of annular forming grooves spaced apart along the axial direction;

[0009] The fixed plate is fixedly installed on the machine base, and the fixed plate is provided with a wire guide groove for the oxygen-free copper after pressing to pass through; the fixed blade holder is fixedly installed on the side of the fixed plate away from the pressing mechanism; the movable blade holder is movably attached to the side of the fixed blade holder away from the fixed plate; the fixed blade holder is detachably provided with a lower cutting blade, and the movable blade holder is detachably provided with an upper cutting blade, the cutting edges of the lower cutting blade and the upper cutting blade are arranged opposite to each other; the slicing drive assembly includes a cam and a slicing drive motor; the cam is installed on the top of the movable blade holder, and the cam rotates one revolution, which can cause the movable blade holder to reciprocate once or multiple times.
[0010] Optionally, the slicing mechanism further includes an elastic reset assembly; the elastic reset assembly includes a reset spring, which is mounted on the end of the movable cutter holder opposite to the cam.
[0011] Optionally, the slicing mechanism further includes an elastic extrusion assembly; the elastic extrusion assembly includes a plurality of extrusion springs and extrusion rollers; the extrusion rollers are mounted on the movable blade holder, or the extrusion rollers are mounted on the side of the extrusion springs facing the movable blade holder;
[0012] The compression spring abuts against the compression roller of the movable cutter holder, or the compression spring abuts the compression roller against the movable cutter holder, so that the movable cutter holder is in close contact with the fixed cutter holder.
[0013] Optionally, at least three compression springs and compression rollers are provided, distributed on the upper and lower sides of the movable blade holder.
[0014] Optionally, the compression spring and compression roller are provided in two sets, distributed on the upper and lower sides of the movable blade holder.

[0019] Optionally, a feeding trough is provided on the side of the machine base away from the forming roller.
[0020] The beneficial effects of this invention are as follows: By replacing traditional sawing with precision shearing via a cam-driven upper cutter, burrs, flash, and microscopic deformation caused by rotating saw blades are fundamentally eliminated. The pure shearing force generated by the cooperation of the lower and upper cutters results in a mirror-like cut, significantly improving the assembly accuracy of the electrode sheet and the reliability of conductive contact, thus avoiding stress concentration hazards. A single rotation of the cam mechanism can drive the movable blade holder to achieve multiple high-speed reciprocating cuts (e.g., with a multi-peak structure designed for the cam profile), breaking through the physical limitations of single-cutting by traditional saw blades. Combined with continuous feeding via a forming mechanism, millisecond-level cutting cycles are achieved, increasing production capacity and breaking through production bottlenecks. When changing product specifications, only the speed of the blade drive motor needs to be adjusted to dynamically adapt to different cutting length requirements, eliminating the need for mechanical limit adjustments or tooling changes. The detachable blade design supports partial blade replacement, further reducing maintenance costs.

[0031] Example
[0032] Reference Figure 1 and Figure 2 The present invention proposes a batch pressing and slicing production equipment for oxygen-free copper, comprising: a workbench 10, a machine base 20, a guide roller group 30, a pressing mechanism 40 and a slicing mechanism 50 disposed on the workbench 10;
[0033] The guide roller group 30 includes several guide rollers for guiding oxygen-free copper wire into the machine base 20; the forming mechanism 40 and the slicing mechanism 50 are mounted on the machine base 20;
[0034] The forming mechanism 40 includes a forming drive assembly 41 and two forming rollers 42; the two forming rollers 42 roll up and down and abut against each other, and the surfaces of the two forming rollers 42 are provided with a number of annular forming grooves spaced apart along the axial direction;
[0035] The slicing mechanism 50 includes a fixed plate 51, a fixed blade holder 52, a movable blade holder 53, and a slicing drive assembly 54;
[0036] A fixed plate 51 is fixedly installed on the machine base 20. The fixed plate 51 is provided with a wire guide groove 511 for the oxygen-free copper after pressing to pass through. A fixed blade holder 52 is fixedly installed on the side of the fixed plate 51 away from the pressing mechanism 40. A movable blade holder 53 is movably attached to the side of the fixed blade holder 52 away from the fixed plate 51. The fixed blade holder 52 is detachably provided with a lower cutting blade 55, and the movable blade holder 53 is detachably provided with an upper cutting blade 56. The cutting edges of the lower cutting blade 55 and the upper cutting blade 56 are arranged opposite to each other. The slicing drive assembly 54 includes a cam 541 and a slicing drive motor 542. The cam 541 is installed on the top of the movable blade holder 53. When the cam 541 rotates one revolution, the movable blade holder 53 can reciprocate once or multiple times.
[0037] In this invention, the precision shearing of the upper cutter 56 driven by the cam 541 replaces traditional sawing, fundamentally eliminating burrs, flash, and micro-deformation caused by rotating saw blades. The pure shearing force formed by the lower cutter 55 and the upper cutter 56 results in a mirror-like cut, significantly improving the assembly accuracy of the electrode sheet and the reliability of conductive contact, and avoiding stress concentration hazards. A single rotation of the cam 541 mechanism can drive the movable blade holder 53 to achieve multiple high-speed reciprocating cuts (e.g., the cam 541 profile is designed with a multi-peak structure), breaking through the physical limitations of single-cutting by traditional saw blades. Combined with the continuous feeding of the forming mechanism 40, millisecond-level cutting cycle time is achieved, increasing production capacity and breaking through production bottlenecks. When changing product specifications, only the speed of the blade drive motor 542 needs to be adjusted to dynamically adapt to different cutting length requirements, without the need for mechanical limit adjustments or tooling changes. The detachable blade design supports partial blade replacement, further reducing maintenance costs.
[0038] In this embodiment, the slicing mechanism 50 further includes an elastic reset component 57; the elastic reset component 57 includes a reset spring, which is installed at the end of the movable cutter holder 53 opposite to the cam 541. The spring forces the movable cutter holder 53 to reset instantaneously, eliminating the return stroke of the cam 541 and ensuring consistency in millions of cutting operations. It also provides impact protection, buffering the mechanical impact at the end of the shearing process, reducing fatigue damage to the mechanism, and extending the equipment's lifespan.
[0039] In this embodiment, the slicing mechanism 50 further includes an elastic compression assembly 58; the elastic compression assembly 58 includes a plurality of compression springs 581 and compression rollers 582; the compression rollers 582 are mounted on the movable blade holder 53, or the compression rollers 582 are mounted on the side of the compression springs 581 facing the movable blade holder 53; the compression springs 581 abut against the compression rollers 582 of the movable blade holder 53, or the compression springs 581 abut against the compression rollers 582 of the movable blade holder 53; so that the movable blade holder 53 is tightly attached to the fixed blade holder 52. The spring assembly dynamically compensates for the tool wear clearance, maintains a tight fit between the movable blade holder 53 and the fixed blade holder 52, and ensures that the upper and lower blade edges are tightly fitted, thus ensuring stable long-term cutting quality. The rollers replace the sliding friction of the movable blade holder 53, reducing resistance and improving the transmission efficiency of the cam 541.
[0040] In this embodiment, at least three compression springs 581 and compression rollers 582 are provided, distributed on the upper and lower sides of the movable cutter holder 53. Preferably, two sets of compression springs 581 and compression rollers 582 are provided, distributed on the upper and lower sides of the movable cutter holder 53. The symmetrical distribution of multiple sets of springs suppresses the overturning moment of the movable cutter holder 53 and avoids slanted cut damage caused by blade misalignment.
[0041] In this embodiment, the base 20 is a structure of fixed plates 51 arranged at relative intervals; the forming roller 42, fixed plates 51, fixed cutter holder 52, movable cutter holder 53, and cam 541 are mounted on the two fixed plates 51 and located between the two fixed plates 51. The double plates bear the axial load of the forming roller 42 / cutter holder, have strong resistance to deformation, and have an ultra-high rigidity frame structure.
[0042] In this embodiment, the slicing mechanism 50 further includes a side guide wheel (not shown in the figure); the side guide wheel is mounted on the fixed plate 51 and is used to abut against the side wall of the movable blade holder 53; or, the side guide wheel is mounted on the movable blade holder 53 and is used to abut against the fixed plate 51. This resists radial movement, constrains the lateral displacement of the movable blade holder 53, and prevents blade chipping caused by lateral slippage of the blade edge during high-speed cutting.
[0043] In this embodiment, the fixed tool holder 52 and the movable tool holder 53 are provided with lubricating oil distribution grooves for applying lubricating grease.
[0044] In this embodiment, the forming drive assembly 41 includes a forming drive motor, a reduction gearbox, and a transmission gear set connected to the forming roller 42.
[0045] In this embodiment, a cutter wire clamping plate 512 is provided on the side of the fixing plate 51 facing the forming roller 42. The copper wire anti-skid line physically limits the direction of the copper wire after forming, preventing the cutting skew caused by the wire detaching from the wire groove 511 during high-speed feeding.
[0046] In this embodiment, a feeding trough 59 is provided on the side of the machine base 20 away from the forming roller 42. After cutting, the electrode sheet automatically slides into the collection trough, reducing manual sorting time and further improving the production cycle.
[0047] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
