Description

Technical Field

[0001] This invention relates to equipment in the field of mechanical technology, specifically a composite lead wire forming device and its process. Background Technology

[0002] Lead wire is a metallic material that is widely used in various fields such as electronics, chemistry and metallurgy due to its excellent properties and multifunctional characteristics. It can also be made into various household items and handicrafts. Lead wire plays an important role in science, industry and daily life.

[0003] A Chinese invention patent with application publication number CN119427065A discloses a steel wire forming process based on high-quality grinding, including a coarse grinding bearing wheel belt, a medium grinding bearing wheel module, and a fine grinding bearing wheel belt module. The steel wire is subjected to medium grinding on the surface in sequence, and multiple precision grinding processes are used to form a high-quality steel wire surface treatment process.

[0004] However, the inventors discovered that the device performs multiple grinding operations on the steel wire with varying degrees of precision, without checking the flatness of the outer surface of the steel wire, thus ignoring the stubborn protrusions on the outer surface of the steel wire that are difficult to grind. Based on this, we propose a composite lead wire forming device and its process. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by installing a telescopic component between the limiting frame and the rotating drum, a color spraying component above the limiting frame, a support rod longitudinally arranged inside the limiting frame, and a grinding roller rotatably mounted on the support rod. When the grinding roller encounters a protrusion during the grinding process, the grinding roller is linked with the limiting frame to lift synchronously and drive the color spraying component to mark the vicinity of the protrusion. The grinding wire is then manually inspected after grinding, and the marked areas are manually ground to prevent stubborn protrusions on the wire from being overlooked.

[0006] To address the aforementioned technical problems, the present invention adopts the following technical solution:

[0007] A composite lead wire forming device includes a support frame and a lead wire disposed on the support frame and passing through the interior of the support frame. A rotating drum is rotatably mounted on the support frame, and several limiting frames are arranged around the rotating drum. The limiting frames are connected to the rotating drum via a telescopic assembly. A color spraying assembly for marking protrusions on the lead wire is arranged above the limiting frames. Each limiting frame has a longitudinally arranged support rod, a grinding roller is arranged in the middle of the support rod, and a drive assembly is arranged at the rear end of the support rod. When the grinding roller encounters a protrusion during grinding, the grinding roller is linked with the limiting frames to lift synchronously and drive the color spraying assembly to mark the vicinity of the protrusion. Afterward, it is reset via the telescopic assembly.

[0008] As a preferred embodiment, the spraying assembly includes a cavity disposed at the upper end of the limiting frame, a bracket for fixing the cavity, a push rod slidably disposed within the cavity, a spring disposed between the push rod and the top surface inside the cavity, an air tube disposed at the other end of the cavity, and a guide rail fixedly disposed on the bracket for supporting the direction of the air tube.

[0009] As a preferred embodiment, a feed pipe is provided on one side of the cavity, and a one-way valve is provided on the feed pipe.

[0010] As a preferred embodiment, the end of the air pipe is located on the side where the grinding roller meets the lead wire, and a high-pressure nozzle is provided at the end of the air pipe.

[0011] As a preferred embodiment, the drive assembly includes a gear a disposed at the end of the support rod, a gear b disposed on the support frame, a gear c fixedly connected to the rotating drum, a drive motor disposed on the support frame, and a gear d disposed on the drive shaft of the drive motor and meshing with gear c.

[0012] As a preferred embodiment, the telescopic assembly includes a column fixedly disposed on the outer side of the rotating drum, a sleeve slidably disposed on the column, and a return spring disposed between the column and the sleeve, wherein the sleeve is fixedly connected to the limiting frame.

[0013] As a preferred embodiment, the other end of the support rod is provided with a telescopic component, and the telescopic component is provided with a silicone protrusion at the junction with the lead wire.

[0014] As another preferred embodiment, the upper surface of the limiting frame is provided with a raised platform, which abuts against the push block at the lower end of the push rod.

[0015] In addition, the present invention also provides a high-efficiency mixing production apparatus for coating production, comprising the following steps:

[0016] a. Pretreatment: Place lead ingots or lead slag in a boiler, refine the molten lead blocks through batching, smelting and other process steps to remove impurities, and then use an extruder to extrude the molten lead into wires and cool and solidify them to become lead wires.

[0017] b. Stretching: The initially formed lead wire is manually pulled into a rolling press. The press moves the lead wire and puts it into the wire drawing machine in order of hole size. After multiple stretching passes, the lead ingot gradually becomes thinner and forms a lead wire.

[0018] c. Pickling: After the lead wire is drawn, it will be covered with a layer of oxides and contaminants, which need to be treated with hydrochloric acid or sulfuric acid to remove the surface impurities.

[0019] d. Annealing: Place the formed lead wire coil into an annealing furnace. After sealing the annealing furnace with fine sand, start the annealing process. First, raise the furnace temperature to 770℃-820℃, turn off the power, and keep the wire at a constant temperature in the furnace for 1-2 hours. Open the lid and cool down to 500℃ before taking it out of the furnace. Lead wire will generate a lot of stress during the drawing process. Annealing can eliminate internal stress and improve the mechanical properties of lead wire.

[0020] The beneficial effects of this invention are:

[0021] 1. In this invention, a support rod is longitudinally arranged inside the limiting frame, a grinding roller is arranged in the middle of the support rod, and a driving component is arranged at the rear end of the support rod. The driving component drives the grinding roller to revolve around the lead wire and rotate on the support rod at the same time, so as to grind the lead wire in multiple directions, making the grinding of the lead wire more thorough and comprehensive.

[0022] 2. In this invention, a color spraying component is provided above the limiting frame, and a telescopic component is provided between the limiting frame and the rotating drum. The protrusions on the lead wire push the grinding roller and support rod open simultaneously. The limiting frame squeezes the color spraying component and marks the area near the protrusions with color, which makes it convenient for manual grinding of stubborn protrusions and avoids the situation where stubborn protrusions on the lead wire are ignored.

[0023] In summary, this equipment has the advantage of more comprehensive and thorough grinding of lead wire, and is especially suitable for the field of mechanical technology. Attached Figure Description

Detailed Implementation

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figures 1 to 8 As shown, a composite lead wire forming device includes a support frame 1 and a lead wire 2 disposed on the support frame 1 and passing through the interior of the support frame 1. A rotating drum 3 is rotatably disposed on the support frame 1. Several limiting frames 4 are disposed around the rotating drum 3. The limiting frames 4 are connected to the rotating drum 3 by a telescopic component 5. A color spraying component 6 for marking protrusions on the lead wire 2 is disposed above the limiting frames 4. A support rod 7 is longitudinally disposed inside each limiting frame 4. A grinding roller 8 is disposed in the middle of the support rod 7. A drive component 9 is disposed at the rear end of the support rod 7. When the grinding roller 8 encounters a protrusion during the grinding process, the grinding roller 8 is linked with the limiting frame 4 to lift synchronously and drive the color spraying component 6 to mark the vicinity of the protrusion. Afterwards, it is reset by the telescopic component 5.

[0038] like Figures 4 to 6 As shown, the spraying component 6 includes a cavity 61 disposed at the upper end of the limiting frame 4, a bracket 62 for fixing the cavity 61, a push rod 63 slidably disposed in the cavity 61, a spring 64 disposed between the push rod 63 and the top surface inside the cavity 61, an air pipe 65 disposed at the other end of the cavity 61, and a guide rail 67 fixedly disposed on the bracket 62 for supporting the direction of the air pipe 65.

[0039] It is worth mentioning that by setting a color spraying component above the limiting frame and a telescopic component between the limiting frame and the rotating drum, the protrusions on the lead wire synchronously push the grinding roller and support rod open, the limiting frame squeezes the color spraying component and marks the area near the protrusions with color, which makes it easier for manual grinding of stubborn protrusions and avoids the situation where stubborn protrusions on the lead wire are ignored.

[0040] like Figures 4 to 6 As shown, a feed pipe 68 is provided on one side of the cavity 61, and a one-way valve 69 is provided on the feed pipe 68. The end of the air pipe 65 is located on the side where the grinding roller 8 and the lead wire 2 meet, and a high-pressure nozzle 651 is provided at the end of the air pipe 65.

[0041] In this embodiment, the push rod 63 presses the spring 64 upward, and the dye in the cavity 61 is squeezed out from the air pipe 65. The one-way valve 69 can prevent the dye from rushing into the feed pipe 68. Similarly, a one-way valve can be set at the air pipe 65 to prevent the dye from retreating from the air pipe 68 when the push rod 63 is reset.

[0042] like Figure 5 As shown, the upper end surface of the limiting frame 4 is provided with a protruding platform 41, which abuts against the push block 631 at the lower end of the push rod 63.

[0043] like Figure 7 As shown, the telescopic assembly 5 includes a column 51 fixedly disposed on the outer side of the rotating cylinder 3, a sleeve 52 slidably disposed on the column 51, and a return spring 53 disposed between the column 51 and the sleeve 52. The sleeve 52 is fixedly connected to the limiting frame 4.

[0044] It is worth mentioning that when the grinding roller 8 encounters a protrusion, the grinding roller 8 drives the support rod 7 and the limit frame 4 to move towards the outer ring of the lead wire 2 under the action of the telescopic component 5, and is reset under the action of the reset spring 53.

[0045] like Figure 7 As shown, the other end of the support rod 7 is provided with a telescopic member 71, and a silicone protrusion is provided at the junction of the telescopic member 71 and the lead wire 2.

[0046] In this embodiment, the telescopic member 71 can support the support rod 7, which can extend the service life of the device.

[0047] like Figure 8 As shown, the drive assembly 9 includes a gear a91 disposed at the end of the support rod 7, a gear b92 disposed on the support frame 1, a gear c93 fixedly connected to the rotating drum 3, a drive motor 94 disposed on the support frame 1, and a gear d95 disposed on the drive shaft of the drive motor 94 and meshing with the gear c93.

[0048] It is worth mentioning that gear d95 is driven to rotate by drive motor 94, thereby driving gear c93 to rotate synchronously with the rotating drum 3. While gear a91 revolves around the lead wire 2, under the action of stationary gear b92, gear a91 and the grinding roller 8 rotate on their own axis.

[0049] Example 2

[0050] A production process for a high-efficiency mixing apparatus for paint production, comprising the following steps:

[0051] a. Pretreatment: Place lead ingots or lead slag in a boiler, refine the molten lead blocks through batching, smelting and other process steps to remove impurities, and then use an extruder to extrude the molten lead into wires and cool and solidify them to become lead wires.

[0052] b. Stretching: The initially formed lead wire is manually pulled into a rolling press. The press moves the lead wire and puts it into the wire drawing machine in order of hole size. After multiple stretching passes, the lead ingot gradually becomes thinner and forms a lead wire.

[0053] c. Pickling: After the lead wire is drawn, it will be covered with a layer of oxides and contaminants, which need to be treated with hydrochloric acid or sulfuric acid to remove the surface impurities.

[0054] d. Annealing: Place the formed lead wire coil into an annealing furnace. After sealing the annealing furnace with fine sand, start the annealing process. First, raise the furnace temperature to 770℃-820℃, turn off the power, and keep the wire at a constant temperature in the furnace for 1-2 hours. Open the lid and cool down to 500℃ before taking it out of the furnace. Lead wire will generate a lot of stress during the drawing process. Annealing can eliminate internal stress and improve the mechanical properties of lead wire.

[0055] The work process is as follows:

[0056] Start the drive motor 94, and the gear d95 drives the gear c93 to rotate synchronously with the drum 3. While the gear a91 revolves around the lead wire 2, it also rotates on its own axis with the grinding roller 8 under the action of the stationary gear b92.

[0057] When the grinding roller 8 encounters a protrusion, the grinding roller 8 drives the support rod 7 and the limit frame 4 to push the push rod 63 upward to squeeze the dye inside the cavity 61 under the action of the telescopic component 5. The dye is sprayed onto the lead wire 2 body through the air pipe 65 and the high-pressure nozzle 651.

[0058] Under the action of spring 64, push rod 63 is reset, and feed pipe 68 replenishes dye into cavity 61.

[0059] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art under the technical guidance of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
