Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrolytic aluminum technology in the non-ferrous metals industry, and in particular to a machine tool for processing anode guide rods. Background Technology
[0002] In electrolytic aluminum production, the anode guide rods of the electrolytic cell become unusable after multiple uses and repairs due to shortening in length and narrowing in width, requiring scrapping and replacement with new rods. The processing method, efficiency, and precision of these new guide rods play a crucial role in the normal production of electrolytic aluminum. However, there is currently no dedicated processing equipment for these guide rods. Although the existing gantry milling machine (model: B2016A) can process anode guide rods, the following problems exist: 1. High cost. Due to the large size of the equipment, there is a "large horse pulling a small cart" phenomenon; 2. The operation is complex, labor-intensive, and the processing precision is difficult to control; 3. During processing, a large amount of machine oil needs to be brushed on to prevent aluminum chips from sticking to the knife, resulting in oil stains on the worktable that are difficult to clean. This makes it very easy for safety accidents to occur when adjusting and tightening the anode guide rod. 4. Low efficiency and low processing accuracy.
[0003] Therefore, those skilled in the art urgently need to develop a machine tool for processing anode guide rods. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a machining tool for anode guide rods.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a machine tool for processing anode guide rods, comprising a lathe, a middle slide plate provided on the lathe, a guide rod frame provided at the front of the lathe, an anode guide rod provided on the guide rod frame, and a clamping assembly provided on the side of the anode guide rod; a worktable provided on the middle slide plate, a steel plate frame provided on the worktable, a drive assembly for controlling the movement of the steel plate frame provided inside the worktable, a horizontal motor provided on the steel plate frame, the output end of the horizontal motor being connected to the cutter head; the cutter head is composed of four rotating blades, and each blade has a cutting tool hole near its outer end, and each cutting tool hole contains a cutting tool.
[0006] Preferably, each cutting tool extends a different distance from the tool hole.
[0007] Preferably, the thickness of the central part of the cutter head is the same as that of the surrounding area, and the connection between the two is relatively thin.
[0008] Preferably, the clamping assembly includes a positioning block and an inclined block that abut against both ends of the anode guide rod. The top of the inclined block is connected to the pressure plate by bolts, and a pad is provided on the side of the inclined block. The positioning block, the pad, and the inclined block are all fixedly connected to the guide rod frame.
[0009] Preferably, the drive assembly includes a lead screw rotatably disposed inside the worktable, one end of the lead screw extending out of the worktable and connected in sequence to a dial and a handle, the top of the worktable having a slide groove aligned with the direction of the lead screw, the steel plate frame slidingly connected to the slide groove, and the bottom of the steel plate frame extending to the slide groove and threadedly connected to the lead screw.
[0010] Compared with the prior art, the beneficial effects of this utility model are: This solution involves modifying obsolete and idle equipment to process and repair anode guide rods, thereby achieving the reuse of old equipment, reducing costs, and fulfilling the purpose of processing and repairing anode guide rods with existing equipment.
[0011] By modifying idle lathes without altering their basic structure, and with easy installation of the worktable and tool turret, these machines can be used for the processing and repair of guide rods.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0017] Please see Figures 1-6 This utility model provides an embodiment: a machine tool for processing anode guide rods, including a lathe 1, a middle slide 4 on the lathe 1, a guide rod frame 2 at the front of the lathe 1, an anode guide rod 3 on the guide rod frame 2, and a clamping assembly on the side of the anode guide rod 3; a worktable 5 on the middle slide 4, a steel plate frame 6 on the worktable 5, a drive assembly for controlling the movement of the steel plate frame 6 inside the worktable 5, a horizontal motor 7 on the steel plate frame 6, the output end of the horizontal motor 7 being connected to a cutter head 8; the cutter head 8 is composed of four rotating blades, and each blade has a cutting tool hole 81 near its outer end, and each cutting tool hole 81 contains a cutting tool.
[0018] Furthermore, the clamping assembly includes a positioning block 10 and an inclined block 12 that abut against both ends of the anode guide rod 3. The top of the inclined block 12 is connected to the pressure plate 13 by bolts, and a pad 11 is provided on the side of the inclined block 12. The positioning block 10, the pad 11 and the inclined block 12 are all fixedly connected to the guide rod frame 2.
[0019] Furthermore, the drive assembly includes a lead screw 51 rotatably disposed inside the worktable 5. One end of the lead screw 51 extends out of the worktable 5 and is connected in sequence to the dial 52 and the handle 53. The top of the worktable 5 is provided with a slide groove aligned with the direction of the lead screw 51. The steel plate frame 6 is slidably connected to the slide groove, and the bottom of the steel plate frame 6 extends to the slide groove and is threadedly connected to the lead screw 51.
[0020] Handle: Can be rotated clockwise or counterclockwise to drive the internal lead screw to move linearly along the Y-axis; Dial: The dial is divided into equal parts, which can control the depth of cut during machining to achieve the thickness requirements of the guide rod.
[0021] The handle drives the lead screw to rotate, and the lead screw nut is fixedly mounted below the worktable with a disc. When the lead screw rotates, it drives the lead screw nut to move the worktable along the Y-axis. The purpose of moving along the Y-axis is to drive the motor and cutter head on the worktable to move, thereby controlling the thickness of the machining guide rod.
[0022] This device selects outdated and idle CW6110050 and CW6163 lathes, whose main parameters are as follows: 1. Maximum workpiece length: 3000mm; Spindle speed range: 4.8-640 r / min; 2. Number of feed rate levels: 64 levels, ranging from 0.06 to 24.3 mm / r; Based on the above technical parameter analysis, the processing requirements for the guide rod length have been met.
[0023] Based on idle CW6110050 and CW6163 lathes, the longitudinal feed of the lathes is used to ensure the straightness of the guide bar machining; the feed rate can be obtained by adjusting the speed change mechanism of the feed box to ensure the surface roughness requirements; the transverse feed of the lathe's middle slide is used to ensure the dimensional requirements of the guide bar machining; the high-speed rotation of the cutter head driven by the motor is used for cutting, and the feed rate is adjusted to complete roughing and finishing.
[0024] In practice, by adding tooling fixtures to the modified equipment, the processing range of the equipment is expanded. For example, chamfering of the anode guide rod (welding joint).
[0025] The bottom of the anode guide rod has a 15×25 chamfer, primarily used for welding to the explosive blocks at the steel claw, serving as a weld joint. Initial machining is done on a milling machine by rotating the milling head. Because the guide rod material is quite sticky, sufficient cutting oil is required; otherwise, "tool sticking" can easily occur. This results in cutting oil splattering during machining, causing significant oil stains on the operator and the floor, and also reduces efficiency. Furthermore, the guide rod machined on the milling machine has a surface contaminated with machine oil, severely affecting weld quality. Therefore, before each weld, all four weld surfaces must be cleaned with gasoline, increasing labor intensity and being environmentally unfriendly.
[0026] To resolve this contradiction, we added another stop (tilt block 12) next to the positioning stop on the guide rod bracket according to the angle requirements (the newly added stop is at a 45-degree angle to the lathe guide rail), and a bracket (guide rod bracket 9). The height of the bracket is the height from the bottom of the guide rod to the ground when the guide rod is placed horizontally. We used the original bolts to fix the guide rod for angle machining. After machining one angle, we loosened the fixing bolts, rotated the guide rod 90 degrees in place, clamped the bolts, and cut. We rotated it three times in sequence to complete the chamfer.
[0027] The specific steps are as follows: 1.1 Remove the tailstock of the lathe; 1.2 Remove the knife holder and small slide plate from the middle slide plate, and connect and tighten them with the 4 fixing bolts in the turntable using a δ12mm steel plate; 1.3 Connect the Y132s-6 horizontal motor to the δ12mm steel plate with bolts and tighten them; The main technical parameters of the Y132s-6 horizontal motor are: speed—960 rpm; power—7.5KW; 1.4. Install a 470mm diameter cutter head on the motor shaft. Figure 4 and Figure 5 ), and install a forward / reverse switch to control the rotation direction of the cutter head; 1.5 Fabrication of the guide rod frame: Install a guide rod frame with a height of 1200mm and a width of 300mm at the front of the lathe. The bottom is connected to the ground and the lathe foundation with a δ10mm steel plate to increase rigidity and prevent vibration during the machining process. 1.6 Align and weld two positioning blocks (the two positioning blocks should be parallel to the longitudinal guide rail of the lathe and have a high surface finish) and bolts on the guide rod frame for positioning and fastening the guide rod.
[0028] Furthermore, each cutting tool extends a different distance from the tool hole 81. The tool hole 81 is a square hole. After a 20*20 high-speed steel cutting tool is installed inside, the tool is adjusted and tightened using bolts. Since each tool extends a different distance, multi-layer cutting can be performed. This design allows for multi-layer cutting, reduces cutting resistance, increases the depth of cut, improves efficiency, and enhances the surface finish of the machined material.
[0029] The cutter head 8 was designed and machined using scrap steel from a 50mm steel plate. During machining, the four tool slots of the cutter head are evenly divided on the circumference and distributed along an involute curve away from the center.
[0030] Furthermore, the thickness of the central part of the cutter head 8 is the same as that of the surrounding area, and the connection between the two is thinner, thereby reducing weight and reducing the load on the motor.
[0031] The working principle of this utility model is as follows: In use, the calibrated guide rod is hoisted onto the guide rod frame, and both ends are clamped against the positioning blocks with bolts. Based on the surface roughness requirements of the drawing, a suitable cutting speed is selected, the control motor is turned on, and the tool is fed in using the intermediate slide, followed by feed. After the first machined surface is completed, the clamping bolts are loosened, the rod is hoisted and rotated 180 degrees, and the machined surface is clamped against the positioning blocks with bolts. The cutting continues until the dimensions required by the drawing are achieved.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
