Description

Technical Field

[0001] This application relates to the field of upward drawing furnace charge technology, specifically an upward drawing furnace charge device. Background Technology

[0002] An upward-drawing furnace is a continuous casting equipment used to produce oxygen-free copper rods or copper rods of specific alloys. Its core feature is that molten copper is drawn vertically upwards from below to solidify and take shape, hence the name "upward-drawing furnace".

[0003] The existing coiling process after discharge from the upward drawing furnace has the following drawbacks: First, the free fall of the bars leads to uneven interlayer gaps and a shift in the center of gravity of the coil; second, loose coils are prone to slipping and tipping when subjected to tension on the unloading rack. Therefore, this application proposes an upward drawing furnace coiling device to solve these problems. Summary of the Invention

[0004] The technical problem to be solved by this application is to overcome the existing defects and provide an upward drawing furnace tray device that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: an upward drawing furnace tray charging device, including a bottom rail, a moving trolley mounted on the bottom rail, a tray rack rotatably connected to the moving trolley, and side frames, one of which is equipped with a mounting plate, an adjustment group, and two connecting arms at the output end of the adjustment group. A first limiting rod is vertically mounted on the connecting arm and rotatably connected to the connecting arm. A lateral adjustment group is mounted on the other side frame, a moving plate is slidably connected to the lateral adjustment group, a second limiting rod is vertically mounted on the moving plate, a pressure roller is horizontally mounted on one side of the second limiting rod, a connecting plate is rotatably connected to the end of the pressure roller away from the tray rack, and the upper end of the connecting plate is connected to the telescopic end of an electric push rod, which is mounted on the moving plate.

[0006] Furthermore, the adjustment assembly includes a geared motor, a gear set, and a motor mounting base. The motor mounting base is fixed on the mounting plate, and the geared motor is mounted on the motor mounting base. The power output shaft of the geared motor passes through the motor mounting base and is connected to the gear set. The gear set is rotatably connected to the mounting plate.

[0007] Furthermore, the gear set includes two pinions and two large gears, which are arranged in a straight line and are rotatably connected to the mounting plate via a rotating shaft. The two pinions mesh with each other, one of which is connected to the power output shaft of the geared motor. The large gear meshes with the outside of the pinion, and the large gear is connected to the connecting arm via a rotating shaft.

[0008] Furthermore, the lateral adjustment assembly includes a mounting beam, a servo motor, a lead screw, a connecting block, and a sliding assembly. The upper surface of the side frame is provided with a mounting beam. The bottom of the mounting plate is connected to the moving plate through the sliding assembly. The upper surface of the moving plate is provided with a connecting block. The connecting block is connected to the lead screw through a lead screw nut. One end of the lead screw is rotatably connected to the mounting beam, and the other end of the lead screw passes through the side frame and is connected to the power output shaft of the servo motor. The servo motor is fixed to the side frame with bolts.

[0009] Furthermore, the sliding assembly includes a slider and a slide rail. Two slide rails are provided on the lower surface of the mounting beam, and the lead screw is located between the two slide rails. The slide rails are connected to the moving plate through the slider.

[0010] Furthermore, the tray rack includes a chassis, a central column, and support legs. The central column is provided on the upper surface of the chassis, and four support legs are evenly distributed on the outer side of the chassis.

[0011] Furthermore, there is a gap between the upper surface of the support leg and the first limiting rod and the second limiting rod.

[0012] Compared with the prior art, this application uses two first limiting rods and one second limiting rod to form a three-point limiting system, which can limit the bar stock on the coil rack. Furthermore, by setting up an adjustment group and a lateral spacing adjustment group, the positions of the first and second limiting rods can be adjusted, thereby ensuring the accuracy of the inner and outer rings of the copper rod coil and preventing the copper rod coil from becoming loose, which would have an adverse effect on subsequent processing. By setting up an electric push rod and a pressure roller, the bar stock can be pressed to ensure the compactness of the copper rod coil. Attached Figure Description

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0018] Please see Figures 1-3 This application provides a technical solution for an upward drawing furnace tray charging device: an upward drawing furnace tray charging device includes a bottom rail 1, a moving trolley 2 is provided on the bottom rail 1, and a tray rack 3 is rotatably connected to the moving trolley 2.

[0019] The mobile vehicle 2 is equipped with two wheels on each side, and a limit plate is provided on the inside of the wheels to prevent the wheels on the mobile vehicle 2 from detaching from the bottom rail 1.

[0020] Furthermore, the tray rack 3 includes a base 26, a central column 27, and support legs 28. The central column 27 is provided on the upper surface of the base 26, and four support legs 28 are evenly distributed on the outer side of the base 26.

[0021] A lifting ring is provided on the central column 27, the chassis 26 is connected to the moving vehicle 2 through the support bearing, and the support leg 28 can support the copper rod of the coil.

[0022] Furthermore, there is a gap between the upper surface of the support leg 28 and the first limiting rod 13 and the second limiting rod 22, so that when the tray rack 3 rotates, the first limiting rod 13 and the second limiting rod 22 cannot interfere with the rotation of the support leg 28.

[0023] It also includes a side frame 4, one of which is equipped with a mounting plate 5, and the mounting plate 5 is equipped with an adjustment group 6.

[0024] Furthermore, the adjustment group 6 includes a reduction motor 7, a gear set 8, and a motor mounting base 9. The motor mounting base 9 is fixed on the mounting plate 5, and the reduction motor 7 is mounted on the motor mounting base 9. The power output shaft of the reduction motor 7 passes through the motor mounting base 9 and is connected to the gear set 8. The gear set 8 is rotatably connected to the mounting plate 5.

[0025] The motor mounting base 9 is fixed to the mounting plate 5 with bolts, and the geared motor 7 is fixed to the motor mounting base 9 with bolts. The geared motor 7 transmits power to the gear set 8, and the gear set 8 drives the two connecting arms 12 to rotate relative to each other, thereby adjusting the position of the first limit rod 13 on the connecting arm 12. This allows the first limit rod 13 to limit the coils of copper rods with different numbers of turns, preventing the copper rods from being stacked loosely and improving the quality of the copper rod coils.

[0026] Furthermore, the gear set 8 includes two pinions 10 and two large gears 11, which are arranged in a straight line and are rotatably connected to the mounting plate 5 via a rotating shaft. The two pinions 10 mesh with each other, and one of the pinions 10 is connected to the power output shaft of the geared motor 7. The large gear 11 meshes with the outer side of the pinion 10, and the large gear 11 is connected to the connecting arm 12 via a rotating shaft.

[0027] Two small gears 10 and two large gears 11 are arranged in a straight line, with the two small gears 10 located between the two large gears and adjacent gears meshing with each other. The power is transmitted to the small gears 10 by the geared motor 7, and the two small gears 10 drive the two large gears 11 to rotate. This causes the large gears 11 to drive the connecting arm 12 and the first limiting rod 13 to rotate around the center point of the large gear 11, thereby adjusting the position of the two first limiting rods 13 so that the first limiting rods 13 can limit the copper rods of different numbers of turns.

[0028] The output end of the adjustment group 6 is provided with two connecting arms 12. A first limiting rod 13 is vertically arranged on the connecting arm 12 and is rotatably connected to the connecting arm 12. A transverse adjustment group 14 is provided on the other side frame 4. A moving plate 21 is slidably connected to the transverse adjustment group 14 and a second limiting rod 22 is vertically arranged on the moving plate 21.

[0029] The two first limiting rods 13 and the second limiting rod 22 form a three-point limiting structure, which can limit the copper rod coil. Furthermore, by setting the adjusting group 6 and the lateral distance adjusting group 14, the distance between the first limiting rod 13 and the second limiting rod 22 can be adjusted so that the first limiting rod 13 and the second limiting rod 22 can limit copper rods with different numbers of turns.

[0030] Furthermore, the lateral adjustment assembly 14 includes a mounting beam 15, a servo motor 16, a lead screw 17, a connecting block 18, and a sliding assembly. The mounting beam 15 is provided on the upper surface of the side frame 4. The bottom of the mounting plate 5 is connected to the moving plate 21 through the sliding assembly. The connecting block 18 is provided on the upper surface of the moving plate 21. The connecting block 18 is connected to the lead screw 17 through the lead screw nut. One end of the lead screw 17 is rotatably connected to the mounting beam 15, and the other end of the lead screw 17 passes through the side frame 4 and is connected to the power output shaft of the servo motor 16. The servo motor 16 is fixed to the side frame 4 by bolts.

[0031] The mounting beam 15 is fixed to the side frame 4 by bolts. The middle part of the mounting beam 15 is hollow. The moving plate 21 is an isosceles triangle. The second limit rod 22 is rotatably connected at the apex position. The sliders 19 are installed at the two bottom corner positions. The connecting block 18 is fixed to the moving plate 21 by bolts. The servo motor 16 is fixed to the side frame 4 by bolts.

[0032] By setting the servo motor 16, power can be provided to the lead screw 17, thereby causing the lead screw 17 to rotate and the moving plate 21 to move along the sliding group, thereby adjusting the position of the second limit rod 22, so that the second limit rod 22 guides the copper rod disc material with different number of turns.

[0033] Furthermore, the sliding assembly includes a slider 19 and a slide rail 20. Two slide rails 20 are provided on the lower surface of the mounting beam 15, and the lead screw 17 is located between the two slide rails 20. The slide rails 20 are connected to the moving plate 21 through the slider 19.

[0034] The slide rail 20 is fixed to the mounting beam 15 by bolts, and the slider 19 is fixed to the moving plate 21 by bolts.

[0035] A pressure roller 23 is horizontally arranged on one side of the second limiting rod 22. A connecting plate 24 is rotatably connected to the end of the pressure roller 23 away from the tray frame 3. The upper end of the connecting plate 24 is connected to the telescopic end of the electric push rod 25. The electric push rod 25 is installed on the moving plate 21.

[0036] The electric push rod 25 is fixed to the movable plate 21 by bolts. The height of the pressure roller 23 can be adjusted by the electric push rod 25, so that the pressure roller 23 can apply pressure to the copper rod, thereby ensuring the tightness of the copper rod coil.

[0037] Furthermore, the pressure roller 23 can be moved upward by the electric push rod 25 as the number of turns of the copper rod increases, so that the pressure roller 23 can perform the pressing operation on the copper rod.

[0038] It is worth noting that the extension of the pressure roller 23 does not exceed the diameter of the copper rod. When it is necessary to perform coiling operations on copper rods of different sizes, the pressure roller 23 needs to be replaced to ensure that the extension of the pressure roller 23 beyond the gear of the second limit rod 22 is not greater than the diameter of the copper rod.

[0039] In use: First, adjust the positions of the two first limit rods 13 and one second limit rod 22. The reduction motor 7 transmits power to the pinion 10, and the two pinions 10 drive the two large gears 11 to rotate. This causes the large gears 11 to drive the connecting arm 12 and the first limit rods 13 to rotate around the center point of the large gears 11, thereby adjusting the positions of the two first limit rods 13.

[0040] Start the servo motor 16, which drives the lead screw 17 to rotate, causing the moving plate 21 to move the second limit rod 22 and the slider 19 along the slide rail 20, thereby adjusting the position of the second limit rod 22. This allows the second limit rod 22 to guide the copper rod coils with different numbers of turns, and the electric push rod 25 drives the connecting plate 24 and the pressure roller 23 to move downward, so that the pressure roller 23 can press the copper rod.

[0041] The copper rods produced by the upper drawing furnace are wound into a disc shape by a winding machine after straightening. The disc then falls onto the disc rack 3 and is limited by two first limiting rods 13 and one second limiting rod 22. The copper rod is then pressed by the pressing roller 23, which can be moved upward by the electric push rod 25 as the number of turns of the copper rod increases, so that the pressing roller 23 can perform the pressing operation on the copper rod.

[0042] When the inner ring reaches the set number of layers, the winding machine adjusts the size of the copper rod winding reel, and at the same time, the adjusting group 6 adjusts the position of the two first limiting rods 13, and the transverse adjusting group 14 adjusts the position of the second limiting rod 13, so as to facilitate the limiting of copper rods with different numbers of layers. The electric push rod 25 drives the connecting plate 24 and the pressure roller 23 to move downward, so that the pressure roller 23 can press the copper rods with different numbers of turns.
