Description

Technical Field

[0001] The invention relates to the technical field of cutting of electrolytic aluminum cover plates, and in particular to a shearing device for a side cover plate of an electrolytic cell. Background Art

[0002] The top of the electrolytic cell is equipped with an arc-shaped top cover, which is composed of multiple arc-shaped cover plates placed in the middle and side cover plates placed at both ends (the top cover is also called the molten pool cover, cover plate, etc.). The top of the side cover plate needs to match the curvature of the arc-shaped cover plate, so the top of the side cover plate needs to be arc-cut as a whole. When making traditional side cover plates, the raw aluminum plate is sent into the tile pressing machine for tile pressing. After the tile pressing is completed, the line is drawn according to the required curvature, and then clamped and fixed on the platform. The cutting machine is manually held to cut along the drawn line. This process is relatively cumbersome, and the following situations often occur: 1. The aluminum plate is large in size and lacks a dedicated cutting platform for placement and clamping; 2. Line drawing requires measurement, which is time-consuming and easily disturbed, and the accuracy is reduced; 3. Due to the large cutting curvature and long arc cutting stroke, manual cutting has the risk of crooked cutting and bad cutting; 4. The whole process is slow to ensure accuracy and precision, resulting in low efficiency. Therefore, a special cutting device is required to meet the production of side cover plates.

[0058] Two track rods 2.9 are provided on the outer side wall of the arc-shaped vertical plate 2.1.3. The cross-section of the track rod 2.9 is circular. The lower track rod 2.9 is fixed to the arc-shaped bottom plate 2.1.2, and the upper track rod 2.9 is fixed to the arc-shaped vertical plate 2.1.3 by a "𠃍"-shaped fixing rod 2.10. The track rod 2.9 is the outer wall of the arc-shaped clamping table 2.

[0059] The cutting device 4 comprises a box body 4.1, a protective shell 4.2, a cutting motor 4.3, a circular blade 4.4, and a supporting wheel assembly 4.5. The bottom of the box body 4.1 is fixed to the top of the protective shell 4.2, the bottom of the protective shell 4.2 is open, the cutting motor 4.3 is fixed to the box body 4.1, the output end of the cutting motor 4.3 passes through one side of the protective shell 4.2 and is fixed to the circular blade 4.4, the bottom of the circular blade 4.4 extends from the bottom opening of the protective shell 4.2 for cutting, and the bottom of the extended circular blade 4.4 is lower than the bottom of the table 1.1;

[0060] The top and side of the box body 4.1 are open, and two pairs of horizontally arranged limiting wheels 4.6 are symmetrically provided in the shell body 2.3. The wheel axles of the limiting wheels 4.6 are rotatably connected to the inner wall of the shell body 2.3. The upper track rod 2.9 passes through the opening of the shell body 2.3, and between the two pairs of limiting wheels 4.6, the wheel surfaces of the limiting wheels 4.6 are in rolling contact with the upper track rod 2.9; the two pairs of horizontal limiting wheels 4.6 clamp the upper track rod 2.9 and can roll along the upper track rod 2.9. The clamping can also make the box body 4.1 structure connected to the upper track rod 2.9. The side opening of the box body 4.1 allows the track rod 2.9 to pass through, and the top opening of the box body 4.1 allows the fixing rod 2.10 to pass through without interference when the box body 4.1 moves on the upper track rod 2.9.

[0061] There are multiple support wheel assemblies 4.5, preferably two, and the support wheel assembly 4.5 includes a support wheel 4.5.1, a convex plate 4.5.2, and a vertical shaft 4.5.3. The support wheel 4.5.1 is vertically placed at the bottom of the convex plate 4.5.2, and the wheel axle of the support wheel 4.5.1 is rotatably connected to the inner wall of the convex plate 4.5.2. The wheel surface of the support wheel 4.5.1 is in rolling contact with the track rod 2.9 below. One end of the vertical shaft 4.5.3 is fixed to the bottom of the convex plate 4.5.2, and the vertical shaft 4.5.3 is rotatably connected to the other side of the protective shell 4.2; the support wheel 4.5.1 Rolling on the track rod 2.9 below can be used to support the downward weight of the cutting device 4. Since the track rod 2.9 is arc-shaped, the moving trajectory of the cutting device 4 on the track rod 2.9 is also arc-shaped. If the two support wheel assemblies 4.5 are fixed side by side, when the cutting device 4 moves in an arc, the support wheel 4.5.1 cannot adapt well, thereby playing a role of hindering interference. The support wheel assembly 4.5 can be adjusted with the rotation relationship between the vertical axis 4.5.3 and the protective shell 4.2, and the support wheel 4.5.1 has good adaptability, so that it moves smoothly.

[0064] It also includes a contact sensor 8 and a PLC controller 9. The contact sensors 8 are fixed at both ends of the arc-shaped top plate 2.1.1. An extension rod 10 is horizontally fixed on the top of the transmission rod 4.7. A diamond-shaped contact block 11 is fixed at the end of the extension rod 10. The diamond-shaped contact block 11 is in active contact with the contact of the contact sensor 8. The signal output end of the contact sensor 8 is connected to the signal input end of the PLC controller 9. The PLC controller 9 is electrically connected to the drive motor 2.6.

[0065] As the cutting device 4 moves on the track rod 2.9, the diamond contact block 11 is driven to make active contact with the contacts of the two contact sensors 8 respectively. After sensing, the contact sensor 8 sends a signal to the PLC controller 9 to control the drive motor 2.6 to stop, and the chain 2.5 to stop moving, causing the cutting device 4 to stop moving; when cutting, the cutting device 4 moves and contacts the contact sensor 8 at one end. After the cutting device 4 stops, the cutting is completed. After stopping, the drive motor 2.6 can be started again to reverse, and the cutting device 4 resets and moves, and contacts the contact sensor 8 at the other end. After the cutting device 4 stops, the reset action is completed and waits for the next cutting.

[0066] Working principle: After placing the aluminum plate, the hydraulic cylinder 3.1 of the lifting device 3 drives the small rectangular sleeve 3.3 to rise in the large rectangular sleeve 3.2, and the arc clamping table 2 is raised above the supporting platform 1. A single aluminum plate is placed on the table 1.1 of a supporting platform 1, so that one aluminum plate can be cut, or double aluminum plates can be placed on the table 1.1 of two supporting platforms 1 at the same time, and two aluminum plates can be cut at the same time, thereby improving efficiency;

[0067] When placing the aluminum plate, the bottom edge and the side edge of the aluminum plate can be clearly positioned by pressing against the limit plate 5.4 of the first adjuster 5 and the L-shaped plate 6.2 of the second adjuster 6. After placing the aluminum plate, the arc-shaped clamping platform 2 is lowered, and the bottom of the arc-shaped bracket 2.1 of the arc-shaped clamping platform 2 presses the aluminum plate onto the platform 1.1 to achieve the effect of clamping and tightening;

[0068] The driving motor 2.6 is started, driving the driving gear 2.7 to drive the driven gear 2.8 to rotate, and then driving a sprocket 2.4 to rotate, so that the chain 2.5 rotates as a whole. The chain 2.5 drives the cutting device 4 to move in an arc on the track rod 2.9 through the short rod 4.8 and the transmission rod 4.7. The cutting motor 4.3 drives the circular blade 4.4 to rotate at a high speed, and the cutting device 4 cuts the aluminum plate in an arc.

[0069] When the present application is used: 1. The table plate 1.1 of the support platform 1 and the extended and detachable support frame 1.6 meet the requirements for placing the aluminum plate; 2. The arc-shaped clamping table 2 descends to clamp the aluminum plate on the support platform 1, which plays a stabilizing role. The cutting device 4 cuts along the arc of the arc-shaped bracket 2.1 of the arc-shaped clamping table 2. When the arc is determined, drawing lines can be avoided, which saves time, improves accuracy, and improves efficiency; 3. Machine cutting is relatively stable, avoiding the risk of crooked or damaged cutting; 4. During the entire operation process, there is no need for manual drawing of lines. One person can operate two aluminum plates at the same time, which is highly efficient.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
