Description

Technical Field

[0001] This utility model relates to the field of nickel-based alloy wire processing technology, specifically a copper-nickel alloy wire fixed-length cutting device. Background Technology

[0002] Nickel-based alloys are a class of alloys that possess high strength and certain resistance to oxidation and corrosion at high temperatures of 650-1000℃. Based on their main properties, they are further subdivided into nickel-based heat-resistant alloys, nickel-based corrosion-resistant alloys, nickel-based wear-resistant alloys, nickel-based precision alloys, and nickel-based shape memory alloys. High-temperature alloys are classified according to their matrix into iron-based, nickel-based, and cobalt-based high-temperature alloys. Nickel-based alloy wire is an alloy wire with nickel as its main component, which maintains good mechanical strength and strong creep resistance even at extremely high temperatures.

[0003] The processing and production of nickel-based alloy wire involves several key steps, including smelting, forming, heat treatment and finishing, and winding. Cutting and forming is a critical step in the production of nickel-based alloy wire. The fixed-length cutting device is a key piece of equipment to ensure that the product meets the specifications. By cutting the nickel-based alloy wire material to a fixed length with a cutter, the length of the wire can be precisely controlled to meet the needs of subsequent processing or direct use. At the same time, it is also conducive to improving production efficiency and material utilization.

[0004] In the above-mentioned process of cutting nickel-based alloy wire, a cutting blade is required to cut the nickel-based alloy wire. However, in the actual cutting process, due to the thinness of the nickel-based alloy wire, the overall tension of the nickel-based alloy wire is prone to be insufficient during the winding and pulling process, resulting in insufficient shearing force when the cutting blade cuts, making it difficult to cut the nickel-based alloy wire and affecting normal production efficiency. To this end, we propose a copper-nickel alloy wire fixed-length cutting device. Utility Model Content

[0011] Furthermore, the cutting groove is formed in a concave arc shape along the inner wall of the main cutting arm and the secondary cutting arm, and the anti-slip groove is made of rubber.

[0020] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] This utility model provides, for example Figure 1-4 The device for cutting copper-nickel alloy wire to a fixed length, as shown, includes a main body 1. A cutting blade assembly 2 is fixed to the center of the top surface of the main body 1. The main body 1 includes a main frame 101, and a control box 102 is fixed to the outer wall of one end of the main frame 101. A workbench 103 is fixed to the top of the main frame 101, and a wire feeding frame 104 is fixed to the top surface of the workbench 103. A Hall effect speed sensor 105 is axially connected to one side of the wire feeding frame 104, and a copper-nickel alloy wire 106 is connected to one side of the wire feeding frame 104. One end of the gold wire 106 is fitted with a limiting frame 107. A cutting wheel 108 is mounted on one side of the top surface of the main frame 101. A rotating shaft 109 is fixed on one side of the cutting wheel 108. A servo motor 110 is connected to the other side of the cutting wheel 108. A main cutting arm 111 and a secondary cutting arm 112 are fixed on the outer walls of both sides of the cutting wheel 108. Cutting grooves 113 are opened on the inner walls of both the main cutting arm 111 and the secondary cutting arm 112. Anti-slip grooves 114 are embedded in the inner walls of the cutting grooves 113. To improve the efficiency of this fixed-length cutting device in the fixed-length cutting process of nickel-based alloy wire, such as... Figure 1-4 As shown, this fixed-length cutting device feeds copper-nickel alloy wire 106 through a feeder frame 104, allowing the material to pass through the feeder frame 104 and connect to the winding equipment. During the feeding process, the copper-nickel alloy wire 106 can be continuously rotated by the wheel of the feeder frame 104 and monitored by a Hall effect speed sensor 105. This allows the microcontroller in the control box 102 to control and regulate the servo motor 110, which in turn drives the cutting wheel 108 to rotate. This will cause the main cutting arm 111 and the auxiliary cutting arm 112 to press down on the cutting blade 203 simultaneously. The cooperation between the main cutting arm 111 and the auxiliary cutting arm 112 and the cutting blade 203 will form a shearing force that presses down on both sides and cuts in the center. The cutting grooves 113 on the inner walls of the main cutting arm 111 and the auxiliary cutting arm 112 can cooperate with the embedded anti-slip grooves 114 to keep the contact friction force of the pressing down on both sides stable, thereby ensuring that the copper-nickel alloy wire 106 can be cut quickly and stably, improving the stability and efficiency of the fixed-length cutting process. The Hall-type speed sensor 105 described above is similar to common existing Hall-type sensors. Its core is the Hall element. When it is energized and placed in a magnetic field, electrons are deflected by the Lorentz force, forming a Hall voltage on both sides of the element. The sensor is usually composed of a permanent magnet, a Hall element, and a signal processing circuit. During operation, the gear or magnet rotates with the shaft being measured, and the convex teeth or magnetic poles on it alternately pass through the Hall element, causing the magnetic field strength to change periodically, thereby generating an alternating Hall voltage pulse signal. The rotation speed and number of rotations are determined by this signal. This type of technology is already quite common in the market, so it will not be described in detail here.

[0022] like Figure 4 As shown, the cutting knife assembly 2 includes a knife holder 201, which is fixed to the center opening on the top surface of the main frame 101. The knife holder 201 has an insertion cavity 202 inside, and a cutting knife 203 is inserted into the insertion cavity 202. A cutting opening 204 is provided at the center of the top of the cutting knife 203. like Figure 4 As shown, this fixed-length cutting device has a knife holder 201 fixed at the center of the top surface of the main frame 101. The knife holder 201 has slits on both sides to accommodate the main cutting arm 111 and the auxiliary cutting arm 112 when they rotate in during cutting and pressing. The knife holder 201 can also be used with the insertion cavity 202 to insert the cutting knife 203 for easy replacement. The cutting opening 204, which is concave arc-shaped at the center of the top surface of the cutting knife 203, facilitates the rapid cutting and positioning of the copper-nickel alloy wire 106.

[0023] In summary, when using this fixed-length cutting device, the copper-nickel alloy wire 106 is first led out by the wheel of the pay-off frame 104, and passes through the pay-off frame 104 and the cutting blade assembly 2 to connect with the external winding device. During the fixed-length cutting process, the wheel of the pay-off frame 104 rotates. At this time, the Hall effect speed sensor 105 connected to one side of the pay-off frame 104 can determine the speed and number of revolutions. When the threshold corresponding to the set number of revolutions is reached, the microcontroller in the control box 102 controls the servo motor 110, which drives the cutting wheel 108 to rotate. The cutting wheel 108 drives the main cutting arm 111 and the auxiliary cutting arm 112 to rotate and press down synchronously, forming a downward pressure on both sides with the cutting blade 203. The central cutting blade 203 cuts the copper-nickel alloy wire 106, thus completing the fixed-length cutting process. The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
