Technical Field

[0001] The utility model relates to the field of copper alloy processing, in particular to a copper alloy wire cutting and cooling device. Background Art

[0002] Copper alloy wires include ordinary performance wires and high-performance wires. The structural characteristics of high-performance wires are the use of copper, copper-silver alloy, high-strength copper-silver alloy, copper-tin alloy, copper-magnesium alloy, high-strength copper-magnesium alloy, etc. For example, the contact wire of the track is also made of high-performance copper alloy, which is mainly used as the contact wire for electrified railway contact network to meet the needs of electrified railway contact network. It is usually necessary to cut chips on both sides of the contact wire, so the chip cutting position needs to be cooled to ensure the service life of the tool.

[0003] However, in current cutting operations, the cutting position is often directly flushed and cooled, and internal energy will remain inside the contact line, which may easily lead to insufficient temperature reduction and subsequent heat transfer affecting the tool. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a copper alloy wire cutting and cooling device, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: a copper alloy wire cutting and cooling device, comprising a cutting frame, wherein two water storage bins are arranged inside the cutting frame, a protective baffle is installed at one end of the upper surface of the two water storage bins, an arc-shaped pad is arranged on the inner side of the protective baffle, a guide roller is installed on the upper surface of the arc-shaped pad through an ear plate, a filter is installed on the side of the two water storage bins close to the protective baffle, a tool slide is opened inside the protective baffle, a cutting tool is arranged inside the tool slide, and a positioning guide rail is installed on the upper surface of the water storage bin below the cutting tool.

[0006] As a further solution of the present invention: a cooling water pipe is provided inside the cutting tool and passes through the water storage bin, and through holes are provided at both ends of the cutting frame, and copper contact wires are provided inside the through holes.

[0007] As a further solution of the present invention: slag discharge openings are opened on both sides of the arc-shaped pad on the lower surface of the cutting frame, and sealed pads are installed inside the slag discharge openings.

[0008] As a further solution of the present invention: the arc-shaped pad is fixedly connected to the cutting frame, and a rotating shaft is connected between the guide roller and the ear plate.

[0009] As a further solution of the present invention: the guide rollers and the arc-shaped pads are both made of copper.

[0010] As a further solution of the present invention: a water pump is installed at the lower end of the cooling water pipe located inside the water storage bin.

[0011] As a further solution of the present invention: the cutting tool is slidably connected to the positioning guide rail.

[0012] As a further solution of the present invention: the sealing pad is rotatably connected to the cutting frame, and a sealing pad is installed on the upper surface of the sealing pad at a position corresponding to the slag discharge port.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The coolant will keep the arc pad and guide roller placed inside immersed to cool them down. At the same time, the lower surface of the copper contact wire will be assisted in transferring heat under the action of the guide roller. At the same time, the lower surface of the copper contact wire will continue to transfer heat under the action of contact with the coolant, which can avoid the continued accumulation of heat inside the copper contact wire and the subsequent heat being transferred to the tool.

[0015] A groove formed between the protective partition and the filter can be used to store coolant for cooling. The filter can filter and intercept the flushed coolant, and can also continue the coolant for soaking and cooling treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-5 As shown, this embodiment provides a copper alloy wire cutting and cooling device, including a cutting frame 1, two water storage bins 101 are provided inside the cutting frame 1, a protective partition 2 is installed at one end of the upper surface of the two water storage bins 101, an arc-shaped pad 202 is provided on the inner side of the protective partition 2, the arc-shaped pad 202 is fixedly connected to the cutting frame 1, a guide roller 203 is installed on the upper surface of the arc-shaped pad 202 through an ear plate, a rotating shaft is connected between the guide roller 203 and the ear plate, the guide roller 203 and the arc-shaped pad 202 are both copper components, the two water storage bins 101 are located on the side close to the protective partition 2 and a filter screen 204 is installed, a tool slide 201 is opened inside the protective partition 2, a cutting tool 4 is provided inside the tool slide 201, and an adjustment guide rail 3 is installed on the upper surface of the water storage bin 101 below the cutting tool 4, and the cutting tool 4 is slidably connected to the adjustment guide rail 3.

[0024] like Figure 2-3 As shown, in this embodiment, a cooling water pipe 401 is provided inside the cutting tool 4 and passes through the water storage bin 101. The lower end of the cooling water pipe 401 is located inside the water storage bin 101 and a water pump is installed. Both ends of the cutting frame 1 are provided with through holes 6, and the copper contact wire 5 is provided inside the through holes 6. Slag discharge ports 102 are provided on both sides of the arc-shaped pad 202 and located on the lower surface of the cutting frame 1. A sealed gasket 103 is installed inside the slag discharge port 102. A sealing gasket is installed on the upper surface of the sealed gasket 103 corresponding to the position of the slag discharge port 102. The sealed gasket 103 is rotatably connected to the cutting frame 1.

[0025] The working principle of the present invention is as follows: when in use, the copper contact wire 5 is inserted into the interior of the cutting frame 1 from one side end of the through-hole 6. The two protective partitions 2 provided inside the cutting frame 1 are respectively located at the two side ends of the two water storage bins 101. A groove formed between the protective partition 2 and the filter 204 can be used to store coolant for cooling. The cutting tool 4 is adjusted to the position of the protective partition 2 inside the adjustment guide rail 3. The copper contact wire 5 is controlled to move back and forth inside the cutting frame 1. The side surface of the copper contact wire 5 and the cutting tool 4 make back and forth contact to perform cutting. At the same time, the cooling water pipe 401 above the cutting tool 4 will pump the coolant inside the cooling water pipe 401 to the cutting position for flushing and cooling. At the same time, the coolant after flushing will fall into the cavity position between the two protective partitions 2 and continue to collect. Therefore, the coolant will keep the arc pad 202 and the guide roller 203 placed inside immersed to cool them. At the same time, the lower surface of the copper contact wire 5 will be assisted in transfer under the action of the guide roller 203. At the same time, the lower surface of the copper contact wire 5 will continue to transfer heat under the action of contact with the coolant, which can avoid the internal heat of the copper contact wire 5 from continuing to accumulate heat, causing subsequent heat to be transferred to the tool.
