Description

Technical Field

[0001] This utility model belongs to the field of metal smelting auxiliary technology, specifically an oxygen-free copper rod feeding device. Background Technology

[0002] Oxygen-free copper rods, as high-performance conductive materials, are widely used in the electronics, power, and communications fields. The current mainstream production process uses the upward continuous casting method, which requires a continuous supply of electrolytic copper or scrap copper to the smelting furnace to maintain a stable copper level.

[0003] The current feeding method generally involves using a crane to hoist copper electrolytic plates to the open furnace opening and then manually feeding them. This method has the advantages of convenient operation and low equipment investment, and is widely used in small and medium-sized production.

[0004] However, as the industry's requirements for production safety and product purity increase, this method can no longer meet the needs of modern manufacturing. Specific shortcomings include:

[0005] 1. Operators are exposed to an open furnace environment with temperatures above 800°C. The risk of steam explosion caused by the contact between the copper plate and the liquid surface at the moment of feeding is difficult to avoid effectively. The splashing of molten copper can easily cause burns.

[0006] 2. The feeding method can easily lead to environmental dust, lifting tool debris and other impurities being mixed into the molten pool, affecting the purity of the copper liquid and causing the product to be unqualified. Utility Model Content

[0020] The relevant technical solutions will now be clearly and completely described with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] Combination Figure 1 and Figure 2 As can be seen, the oxygen-free copper rod feeding device disclosed in this embodiment includes a raw material turning component 1, a material distributing component 2, and a feeding component 3.

[0022] The raw material flipping assembly 1 includes a raw material platform 11, a raw material flipping table 12, a flipping sprocket 13, and a flipping motor 14.

[0023] The raw material platform 11 is a horizontally positioned metal tabletop fixed to the ground, used to support electrolytic copper plates or scrap copper raw materials to be processed. A slot is cut into the right end of the platform, and ear plates are provided on both the front and rear sides of the slot.

[0024] The raw material turning table 12 is L-shaped, with two vertical semicircular plates facing each other on the bottom surface of its long plate. A semicircular turning sprocket 13 is fixed to the semicircular plate near the short plate of the raw material turning table.

[0025] The raw material turning table 12 is hinged to the ear plate of the raw material platform 11 via the turning sprocket 13. It is initially placed horizontally and its surface is provided with anti-slip texture to fix the copper electrolysis plate.

[0026] A chain is provided around the sprocket 13; the sprocket motor 14 is fixed on the raw material platform 11; the sprocket meshes with the output end of the sprocket motor through the chain.

[0027] The raw material turnover table, turnover sprocket, and turnover motor here constitute a distance-saving and labor-saving lever. The motor drives the sprocket, which is more labor-saving than directly driving the raw material turnover table, and is more suitable for small-power motors, thus saving costs.

[0028] The flipping motor 14 of the raw material flipping component 1 can drive the flipping sprocket 13 to rotate, causing the raw material flipping table 12 to flip from a horizontal state to an inclined state, so that the copper electrolysis plate can be stably erected, making it easier for the subsequent material distribution component to grab it.

[0029] The material distribution assembly 2 includes a material distributor 21, a vacuum suction cup 22, a material distribution guide column 23, and a material distribution upper and lower motor 24.

[0030] The feeder 21 is a telescopic electric push rod, which is horizontally installed on the left side of the raw material platform 11, and a vacuum suction cup 22 is fixed at its end.

[0031] The vacuum suction cup 22 is connected to an external vacuum pump via an air pipe. The suction cup surface is equipped with a pressure sensor for adsorbing a single copper electrolytic plate.

[0032] The material distribution guide column 23 consists of four vertically arranged guide rails, and the bases at the four corners of the material distribution machine 21 are all slidably connected to the material distribution guide column 23 via sliders.

[0033] The material distribution motor 24 is a servo motor, which drives the material distributor 21 to move up and down along the material distribution guide column 23 through a lead screw mechanism.

[0034] The material distribution assembly 2 is driven by the upper and lower motors 24 to move the material distributor 21 downwards. The material distributor drives the vacuum suction cup 22 to the surface of the copper electrolytic plate. After the vacuum suction cup adsorbs a single copper electrolytic plate, the material distributor 21 retracts and raises the copper electrolytic plate to the upper limit of the material distribution guide post 23, thus completing the separation of a single raw material.

[0035] The feeding assembly 3 includes a feeding rack 31, a transverse trolley 32, a transverse reduction motor 33, a feeding guide column 34, a feeding up and down motor 35, a raw material clamp 36, and a clamp jaw 37.

[0036] The feeding rack 31 is a gantry frame, with the left side of the frame spanning above the charging port of the smelting furnace and the right side of the frame located above the material distribution component 2; the top of the feeding rack is a horizontal guide rail.

[0037] The transverse trolley 32 is slidably connected to the guide rail of the feeding rack 31 via rollers, and the transverse reduction motor 33 drives the transverse trolley 32 to move along the guide rail via a gear and rack mechanism; the transverse trolley is equipped with a protective cover to protect the transverse reduction motor.

[0038] The feeding guide post 34 is a guide post that is vertically fixed to the bottom of the transverse trolley 32, and the raw material clamp 36 is slidably connected to the feeding guide post through a slider.

[0039] The feeding motor 35 is fixed inside the protective cover of the transverse trolley 32 and drives the raw material clamp 36 to rise and fall along the feeding guide column 34 through the screw drive.

[0040] The raw material clamp 36 has symmetrical clamp jaws 37 at its end, and the inside of the jaws is lined with a high-temperature resistant ceramic liner. The clamps are opened and closed by hydraulic drive.

[0041] After the feeding assembly 3 and the dividing assembly 2 lift the copper plate, the feeding motor 35 drives the raw material clamp 36 to descend to the clamping position. The clamp jaws 37 close and hold the copper electrolytic plate. Then, the transverse reduction motor 33 drives the transverse trolley 32 to move to the top of the charging port of the smelting furnace and slowly immerses the copper electrolytic plate into the copper liquid to complete the feeding.

[0042] The workflow for using this device for coordinated feeding is as follows:

[0043] 1. Lift the copper electrolysis plate onto the horizontal platform of the raw material turning table 12.

[0044] 2. The flipping motor 14 drives the flipping sprocket 13 to rotate, causing the raw material flipping table 12 to tilt to 85°, and the copper plate to be in a vertical and stable state.

[0045] 3. The upper and lower motors 24 drive the material distributor 21 to move downwards. After the vacuum suction cup 22 adsorbs the copper plate, it retracts and the material distributor 21 is raised to the upper limit.

[0046] 4. The feeding motor 35 drives the raw material clamp 36 to move downward. After the clamp jaws 37 clamp the copper plate, the material distribution component 2 returns to its original position.

[0047] 5. The transverse reduction motor 33 drives the transverse trolley 32 to move along the feeding rack 31 to the charging port of the smelting furnace. The feeding up and down motor 35 controls the raw material clamp 36 to immerse the copper plate into the copper liquid at a constant speed to avoid splashing.

[0048] 6. After feeding is completed, the clamp jaws 37 open, the traverse carriage 32 returns to the initial position, and the next feeding cycle begins.

[0049] The tilting motor 14, the material distribution motor 24, the transverse reduction motor 33, and the feeding motor 35 of this device are all controlled by a PLC program; the lifting position of the raw material clamp 36 and the travel endpoint of the transverse trolley 32 are positioned by photoelectric switch feedback to ensure the accuracy of the action.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
