Description

Technical Field:

[0001] The present invention relates to the technical field of ferrosilicon production, and particularly relates to an electrode cylinder assembly and welding system for ferrosilicon production. Background Art:

[0002] The electric furnace is a key equipment in the ferrosilicon production process. An electrode carbon rod in the electric furnace is sheathed with an electrode cylinder (also called a motor shell). The electrode cylinder is a cylinder composed of multiple arc-shaped side walls. The edges of the arc-shaped side walls are upturned into long strip planes. A long rib plate is clamped between the long strip plane edges of two adjacent arc-shaped side walls. Each rib plate faces the center of the cylinder. When fixing, it is necessary to weld the welding surfaces formed by the long strip plane edges of two adjacent arc-shaped side walls and the rib plate.

[0003] In the existing electrode cylinder assembly process, mostly cylindrical inner and outer support frames are made to support the cylindrical electrode cylinder formed by the butting of the edges of the arc-shaped side plates. First, manual spot welding is used for temporary shaping, and then manual welding is used for fixing. This process is time-consuming and laborious, with low efficiency and easy to cause low yield. There is an urgent need for an electrode cylinder assembly and welding device that can reduce the number of personnel used, reduce labor intensity, increase production capacity and improve the yield.

Specific embodiments:

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Such as Figures 1 to 12As shown in the figure, an electrode cylinder assembly and welding system for ferrosilicon production includes a track 1, an electrode cylinder assembly rack 2, and an alternating current circumferential seam welding machine 3. The electrode cylinder assembly rack 2 is slidably arranged on the track 1. The electrode cylinder assembly rack 2 includes a vehicle chassis 2.1. Two brackets 2.2 are symmetrically and fixedly arranged on the top of the vehicle chassis 2.1. Two discs 2.3 are symmetrically arranged between the two brackets 2.2. Notches for placing long rib plates are also circumferentially arranged on the discs 2.3. The two discs 2.3 are vertically and coaxially arranged. Rotating shafts 2.4 are respectively fixed at the centers of the opposite disc surfaces of the two discs 2.3. The rotating shaft 2.4 of one disc 2.3 is rotatably connected to the corresponding bracket 2.2. The rotating shaft 2.4 of the other disc 2.3 penetrates through the corresponding bracket 2.2. An adjusting cylinder 2.5 is coaxially arranged on one side of the rotating shaft 2.4 penetrating through the bracket 2.2. The end of the telescopic rod of the adjusting cylinder 2.5 is rotatably connected to the end of the rotating shaft 2.4 penetrating through the bracket 2.2. The top of the adjusting cylinder 2.5 is fixedly connected to the adjacent bracket 2.2 through a cross beam 2.6;

[0042] Lay multiple arc-shaped side plates of the electrode cylinder between the two discs 2.3 and surround them into a cylindrical shape along the discs 2.3. Then place the long rib plates in the notches of the two discs 2.3 respectively. The long rib plates are clamped by the long strip plane edges of the two arc-shaped side plates, and a welding surface is formed and temporarily fixed by spot welding. The adjusting cylinder 2.5 drives the distance between one disc 2.3 and the other disc 2.3. When they are far apart, it is convenient to remove the electrode cylinder;

[0043] An alternating current circumferential seam welding machine 3 is arranged on one side of the track 1. The alternating current circumferential seam welding machine 3 includes two pairs of welding wheels 4 and a welding housing 5. The rotation directions of the two pairs of welding wheels 4 are opposite. The notches of the discs 2.3 of the electrode cylinder assembly rack 2 are correspondingly arranged with the upper and lower wheel gaps of the two pairs of welding wheels 4 of the alternating current circumferential seam welding machine 3;

[0044] Any one pair of welding wheels 4 includes two active circular electrodes 4.1 and two driven circular electrodes 4.2 symmetrically arranged up and down, a three-phase stepless speed regulation motor 4.3, and an adjustable stroke cylinder 4.4. The adjustable stroke cylinder 4.4 is fixed to the welding housing 5. The end of the piston rod of the adjustable stroke cylinder 4.4 is fixed to the three-phase stepless speed regulation motor 4.3. The output shaft of the three-phase stepless speed regulation motor 4.3 is coaxially fixed to the active circular electrode 4.1. The driven circular electrode 4.2 is rotatably connected to the welding housing 5. The adjustable stroke cylinder 4.4 drives the active circular electrode 4.1 to move up and down. When it descends, the active circular electrode 4.1 and the driven circular electrode 4.2 clamp the welding surface of the electrode cylinder. The three-phase stepless speed regulation motor 4.3 drives the corresponding active circular electrode 4.1 to rotate in one direction, and at the same time moves the electrode cylinder in the same direction. The active circular electrode 4.1 and the driven circular electrode 4.2 rotate in opposite directions. The wheel surfaces of the active circular electrode 4.1 and the driven circular electrode 4.2 are respectively in contact with the top and bottom surfaces of the welding surface to weld the welding surface;

[0045] The rotation directions of the output shafts of the three-phase stepless speed regulation motors 4.3 of the two pairs of welding wheels 4 are opposite, and the rotation directions of the active circular electrodes 4.1 of the two pairs of welding wheels 4 are opposite. As Figure 1 shown, in this embodiment, the active circular electrode 4.1 on the left side of the AC circumferential seam welding machine 3 rotates clockwise, while the active circular electrode 4.1 on the right side rotates counterclockwise; for specific operation, when the electrode cylinder assembly rack 2 carries the electrode cylinder and travels rightward along the track 1, the pair of welding wheels 4 on the left side of the AC circumferential seam welding machine 3 do not move. When the welding surface of the electrode cylinder passes over the welding wheels 4 on the left side and moves to the pair of welding wheels 4 on the right side of the AC circumferential seam welding machine 3, the active circular electrode 4.1 on the right side descends and rotates simultaneously to weld the welding surface; after welding is completed, replace the welding surface to be welded, reverse the electrode cylinder assembly rack 2, and carry the electrode cylinder to travel leftward along the track 1. At this time, the pair of welding wheels 4 on the right side reset and do not move. When the welding surface of the electrode cylinder passes over the welding wheels 4 on the right side and moves to the pair of welding wheels 4 on the left side of the AC circumferential seam welding machine 3, the active circular electrode 4.1 on the left side descends and rotates simultaneously to weld the welding surface; through the setting of the two pairs of welding wheels 4, welding can be performed during the reciprocating movement of the electrode cylinder, simplifying the welding steps and improving the welding efficiency;

[0046] Support rods 6 are respectively fixed at the tops of the two brackets 2.2. A long shaft 7 is provided between the tops of the two support rods 6. One end of the long shaft 7 is rotatably connected to the corresponding support rod 6, the other end of the long shaft 7 passes through the corresponding support rod 6 and is fixed to the handwheel 8, and a cylindrical gear 9 is sleeved and fixed on the long shaft 7; on the two rotating shafts 2.4, plate-shaped gears 10 are respectively coaxially sleeved and fixed. The diameter of the plate-shaped gear 10 is smaller than the diameter of the disc 2.3. Transmission gears 11 are respectively meshed above the two plate-shaped gears 10. One transmission gear 11 is rotatably connected to the corresponding support rod 6, and the other transmission gear 11 is rotatably connected to one end of a transmission cross bar 12 passing through the corresponding support rod 6. The other end of the transmission cross bar 12 is fixed to one end of a transmission vertical rod 13. The other end of the transmission vertical rod 13 passes through a stroke groove 14 provided on the cross beam 2.6 and is fixed to the piston rod of the adjustment cylinder 2.5. The two transmission gears 11 are respectively meshed with the cylindrical gear 9;

[0047] Turn the handwheel 8 to drive the long shaft 7 to rotate, thereby enabling the cylindrical gear 9 on the long shaft 7 to drive the two plate-shaped gears 10 to rotate synchronously through the transmission gears 11, and finally realizing the synchronous rotation of the two discs 2.3. In this way, the notches on the two discs 2.3 are always aligned, providing convenience before installing the electrode cylinder. After the electrode cylinder is formed into a cylindrical shape, the two synchronously rotating discs 2.3 drive the electrode cylinder to rotate, and the welding surface can be conveniently replaced;

[0048] During the process of adjusting the distance between the two discs 2.3 by the adjusting cylinder 2.5, the driving vertical rod 13 will also be driven to move within the stroke slot 14. The driving vertical rod 13 drives a driving gear 11 to move synchronously with the corresponding meshing flake gear 10 through the driving cross rod 12. Moreover, the length of the cylindrical gear 9 is long. When this driving gear 11 moves, it always meshes with the cylindrical gear 9, thus not affecting the transmission connection for the synchronous rotation of the discs 2.3;

[0049] A first cross rod 15 is horizontally fixed on the bracket 2.2 rotatably connected to the rotating shaft 2.4. The first cross rod 15 is parallel to the disc surface of the adjacent disc 2.3. A sleeve 16 is vertically and perpendicularly fixed at the end of the first cross rod 15. A screw rod 17 is inserted into the sleeve 16. A through slot 24 is arranged axially on the side wall of the sleeve 16. A slider 25 that slides within the through slot 24 is fixed on the screw rod 17. A nut 18 is coaxially and rotatably connected to the bottom end of the sleeve 16. The screw rod 17 is threadedly connected to the nut 18. A second cross rod 19 parallel to the first cross rod 15 is fixed at the top end of the screw rod 17. A stop rod 20 is horizontally rotatable at the end of the second cross rod 19. The axial direction of the stop rod 20 corresponds to the gap between the upper and lower wheels of the two pairs of welding wheels 4. A tension spring 21 is fixed between the end of the stop rod 20 facing the disc 2.3 and the second cross rod 19;

[0050] A number of locking blocks 22 are fixed on the edge of the disc surface of the flake gear 10 rotatably connected to the rotating shaft 2.4 on the bracket 2.2. The bottom end of the locking block 22 is inclined. The number of locking blocks 22 is arranged along the circumference of the corresponding flake gear 10, and each locking block 22 corresponds to the position of the welding surface of an electrode cylinder. The locking block 22 is movably sleeved on the stop rod 20. A groove 23 is provided on the side end of the locking block 22 away from the flake gear 10, and the groove 23 is movably sleeved on the stop rod 20;

[0051] Each locking block 22 on the edge of the disc surface of the flake gear 10 corresponds to a notch on one side of the disc 2.3. And each notch on each disc 2.3 corresponds to a welding surface that needs to be welded on the electrode cylinder. Furthermore, each locking block 22 corresponds to a welding surface that needs to be welded; The axial direction of the stop rod 20 corresponds to the wheel gap between the driving circular electrode 4.1 and the driven circular electrode 4.2 of the two pairs of welding wheels 4. For example Figure 7As shown, in this embodiment, the electrode cylinder is rotated counterclockwise, so that any one of the locking blocks 22 on the sheet gear 10 presses down the stop lever 20. Guided by the inclination at the bottom end of the locking block 22, the stop lever 20 is driven to rotate horizontally passively, and the tension spring 21 is stretched. When the groove 23 of the locking block 22 aligns with the stop lever 20, the pulling force of the tension spring 21 drives the stop lever 20 to reset. The stop lever 20 enters the groove 23 to limit the locking block 22, thereby restricting the rotation of the electrode cylinder. At this time, the welding surface corresponding to the restricted locking block 22 is aligned with the wheel gap between the active circular electrode 4.1 and the driven circular electrode 4.2, which is convenient for accurately controlling the position of the welding surface, eliminating the need for manual positioning, alignment, and locking, and improving the operation convenience; manually rotating the stop lever 20 to exit from the previous groove 23, the above-mentioned rotation of the electrode cylinder can be continued to replace the welding surface, with a simple, time-saving, and more efficient process;

[0052] Among them, rotating the nut 18 forward or backward to raise or lower the screw rod 17 can drive the stop lever 20 to rise or fall through the second cross bar 19, thereby adjusting the alignment of the stop lever 20 in the axial direction with the wheel gap between the active circular electrode 4.1 and the driven circular electrode 4.2; when the screw rod 17 moves up and down in the sleeve 16, it drives the slider 25 to slide in the through groove 24 to prevent the screw rod 17 from rotating self - axially;

[0053] One side of the top end of the screw rod 17 is rotatably connected with a laser connecting rod 26 arranged horizontally side by side with the second cross bar 19. A laser emitter 27 is fixed at the end of the laser connecting rod 26. The laser beam direction of the laser emitter 27 is the same as the axis direction of the stop lever 20. On the welding housing 5, there are fixed targets 28 corresponding to the upper and lower wheel gaps of the two pairs of welding wheels 4 to cooperate with the laser beam of the laser emitter 27;

[0054] To further improve the convenience of adjusting the alignment of the stop lever 20 in the axial direction with the wheel gap between the active circular electrode 4.1 and the driven circular electrode 4.2, the laser beam direction of the laser emitter 26 is set to be the same as the axial direction of the stop lever 20. On the welding housing 5, there are fixed targets 27 corresponding to the wheel gap between the active circular electrode 4.1 and the driven circular electrode 4.2 to cooperate with the laser beam of the laser emitter 26. Adjusting the laser beam of the laser emitter 26 to aim at the target 27 can align the axial direction of the stop lever 20 with the wheel gap between the active circular electrode 4.1 and the driven circular electrode 4.2; when the electrode cylinder moves through the AC circumferential seam welding machine 3 for welding, rotate the connecting rod 26 to make way;

[0055] Outside the outer side of the track 1, a guiding vertical plate 29 is arranged side by side. On one side of the bottom of the electrode cylinder assembly rack 2 facing the guiding vertical plate 29, at least one guiding and clamping device 30 is provided; the guiding and clamping device 30 includes a first pair of side plates 30.1 and a second pair of side plates 30.2 respectively arranged on both sides of the guiding vertical plate 29. The first pair of side plates 30.1 is placed inside the guiding vertical plate 29, and the second pair of side plates 30.2 is placed outside the guiding vertical plate 29. A first rectangular frame 30.3 is fixed between the first pair of side plates 30.1. A first guiding wheel 30.4 is horizontally rotatably arranged inside the first rectangular frame 30.3. The first guiding wheel 30.4 is in rolling contact with the guiding vertical plate 29. A second rectangular frame 30.5 is slidably connected between the second pair of side plates 30.2. A second guiding wheel 30.6 is horizontally rotatably arranged inside the second rectangular frame 30.5. The second guiding wheel 30.6 is in separate rolling contact with the guiding vertical plate 29;

[0056] A tension spring 21 is fixed between the tops of the first rectangular frame 30.3 and the second rectangular frame 30.5. The top of the first rectangular frame 30.3 is fixed with an electric push rod 30.7. The end of the piston rod of the electric push rod 30.7 is in separate abutment with the top plate 30.8 fixed on the top of the second rectangular frame 30.5;

[0057] It further includes a proximity switch 31. The receiving end and the transmitting end of the proximity switch 31 are respectively arranged on the guiding and clamping device 30 and on one side of the alternating current loop seam welding machine 3. The signal output end of the proximity switch 31 is in signal connection with the signal receiving end of the electric push rod 30.7.

[0058] When the electrode cylinder assembly rack 2 moves on the track 1 towards the alternating current loop seam welding machine 3, the first guiding wheel 30.4 rolls against the guiding vertical plate 29, playing a role in guiding and preventing derailment. The piston rod of the electric push rod 30.7 abuts against the top plate 30.8 on the second rectangular frame 30.5, driving the second rectangular frame 30.5 away from the guiding vertical plate 29, so that the second guiding wheel 30.6 is away from the guiding vertical plate 29. At the same time, the tension spring 21 is stretched, and there is a gap between the second guiding wheel 30.6 and the guiding vertical plate 29, improving the smoothness of the movement of the electrode cylinder assembly rack 2;

[0059] When the electrode cylinder assembly rack 2 brings the electrode cylinder near the AC circumferential seam welding machine 3 and before entering the AC circumferential seam welding machine 3, the proximity switch 31 sends a signal to the electric push rod 30.7. The piston rod of the electric push rod 30.7 resets and retracts, and the force against the top plate 30.8 on the second rectangular frame 30.5 disappears. The tension spring 21 retracts under the action of the elastic force, driving the second rectangular frame 30.5 to slide towards the guiding vertical plate 29, causing the second guiding wheel 30.6 to roll along the guiding vertical plate 29. There is no gap between the second guiding wheel 30.6 and the guiding vertical plate 29. Under the action of the tension spring 21, the second guiding wheel 30.6 is pressed tightly against the guiding vertical plate 29, achieving the clamping of the guiding vertical plate 29 by the second guiding wheel 30.6 and the first guiding wheel 30.4, increasing the friction between the second guiding wheel 30.6 and the first guiding wheel 30.4 against the guiding vertical plate 29, making the electrode cylinder assembly rack 2 not shake during movement, improving stability, facilitating the welding surface to accurately and effectively enter the gap between the active circular electrode 4.1 and the driven circular electrode 4.2, without pausing for adjustment, improving work efficiency, and also avoiding damage to the electrode cylinder or the welding wheel 4.

[0060] Working principle:

[0061] Assembling the electrode cylinder: Adjust the distance between the two discs 2.3 to a suitable position by adjusting the cylinder 2.5. Place multiple arc-shaped side plates of the electrode cylinder between the two discs 2.3 and surround them into a cylindrical shape along the discs 2.3. Then place the long rib plates into the notch openings of the two discs 2.3 respectively. The long rib plates are clamped by the long plane edges of the two arc-shaped side plates, forming a welding surface and temporarily fixing it by spot welding.

[0062] Before welding the electrode cylinder: As Figure 7 shown, in this embodiment, turn the handwheel 8. Drive the two discs 2.3 to rotate synchronously through the cylindrical gear 9, the transmission gear 11, and the plate-shaped gear 10. The electrode cylinder on the disc 2.3 rotates counterclockwise. Any one of the locking blocks 22 on the plate-shaped gear 10 presses down the stop lever 20 and is sleeved on the stop lever 20 through the groove 23 to limit the rotation of the electrode cylinder. At this time, the welding surface corresponding to the locked locking block 22 faces the gap between the active circular electrode 4.1 and the driven circular electrode 4.2.

[0063] When welding the electrode cylinder: Move the electrode cylinder assembly rack 2 along the track 1 towards the AC circumferential seam welding machine 3. Before the electrode cylinder assembly rack 2 enters the AC circumferential seam welding machine 3, the proximity switch 31 sends a signal to the electric push rod 30.7. The electric push rod 30.7 resets, and the tension spring 21 retracts under the action of the elastic force, driving the second guiding wheel 30.6 to roll along the guiding vertical plate 29. The second guiding wheel 30.6 and the first guiding wheel 30.4 clamp the guiding vertical plate 29, increasing the friction against the guiding vertical plate 29, making the electrode cylinder assembly rack 2 move more stably, and the welding surface can accurately and effectively enter the gap between the active circular electrode 4.1 and the driven circular electrode 4.2;

[0064] AsFigure 1 As shown in the figure, in this embodiment, when the electrode cylinder assembly rack 2 carries the electrode cylinder and travels to the right along the track 1, a pair of welding wheels 4 on the left side of the AC circumferential seam welding machine 3 do not move. When the welding surface of the electrode cylinder passes over the left welding wheel 4 and moves to a pair of welding wheels 4 on the right side of the AC circumferential seam welding machine 3, the active circular electrode 4.1 on the right side descends and rotates simultaneously to weld the welding surface;

[0065] After welding is completed, replace the welding surface to be welded. Manually rotate the shift lever 20 to withdraw from the previous groove 23, and turn the handwheel 8 to drive the electrode cylinder to rotate. The next locking block 22 is sleeved on the shift lever 20 through the groove 23 to limit the rotation of the electrode cylinder, completing the replacement of the welding surface;

[0066] At this time, the electrode cylinder assembly rack 2 can be reversed. Similarly, the proximity switch 31 drives the second guide wheel 30.6 and the first guide wheel 30.4 to clamp the guide vertical plate 29, increasing the friction with the guide vertical plate 29 and improving the stability of the movement of the electrode cylinder assembly rack 2, so that the welding surface can accurately and effectively enter the wheel gap between the active circular electrode 4.1 and the driven circular electrode 4.2;

[0067] Carry the electrode cylinder and travel to the left along the track 1. At this time, a pair of welding wheels 4 on the right side are reset and do not move. When the welding surface of the electrode cylinder passes over the right welding wheel 4 and moves to a pair of welding wheels 4 on the left side of the AC circumferential seam welding machine 3, the active circular electrode 4.1 on the left side descends and rotates simultaneously to weld the welding surface;

[0068] After reciprocating travel, all the welding surfaces on the electrode cylinder are welded, and the electrode cylinder assembly rack 2 is retracted to the original position.

[0069] After welding the electrode cylinder: The adjusting cylinder 2.5 drives one disc 2.3 away from the other disc 2.3 to remove the electrode cylinder.

[0070] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
