Description

Technical Field

[0001] The invention relates to the field of copper tube milling, and in particular to a casting blank shifting mechanism and system. Background Art

[0002] In the copper processing industry, the surface of the ingot pulled out of the melting casting will be oxidized, and the oxide scale must be milled off by the milling machine before rolling, drawing and other subsequent processes. Usually, the ingot pulled out of the melting casting is first stored on an inclined material storage table, and the ingot rolls onto the conveyor roller under the action of its own gravity. The loading mechanism on the conveyor roller transfers the ingot to the milling machine for milling of the surface oxide scale.

[0003] In order to prevent too much slab from sliding down onto the conveyor roller, a slab guard is provided on the material storage table near the conveyor roller. Figure 1 and Figure 2 ,in Figure 1 This is a schematic diagram of the installation of the current billet protection mechanism; Figure 2 This is a schematic diagram of the structure of the current billet protection mechanism. Figure 1 As shown, one end of the material storage platform 1 is connected to the billet traction mechanism 2, and the other end is connected to the conveyor roller 3, and is tilted toward one side of the conveyor roller; the billet protection mechanism 4 is arranged below the connection between the material storage platform 1 and the conveyor roller 2. Figure 2 As shown, the billet shielding mechanism 4 includes a bracket 41, a shielding cylinder 42, a rotating arm 43, a first blocking rod 44 and a second blocking rod 45; the bracket 41 is arranged on the conveying roller and extends toward the material storage platform, and the bracket 41 is provided with a first guide sleeve and a second guide sleeve along the rolling direction of the billet; the shielding cylinder 42 is installed on the outer side of the conveying roller and is located below the bracket 41; the rotating arm 43 is axially connected to the shielding cylinder 42 through a connecting shaft; the first blocking rod 44 and the second blocking rod 45 are respectively hinged to the rotating arm 43 through a first connecting rod and a second connecting rod, and the first blocking rod 44 and the second blocking rod 45 are respectively extended or retracted from the first guide sleeve and the second guide sleeve under the drive of the shielding cylinder 42. In this way, the first blocking rod 44 and the second blocking rod 45 are extended or retracted in an interlaced manner, thereby blocking the billet that is constantly rolling down, so that the billet can be controlled and orderly rolled onto the conveying roller.

[0004] However, the current ingot protection mechanism has the following problems: when the molten ingot is bent or the front and rear rolling are not synchronized, the ingot will stay on the material storage table and cannot roll down automatically, and it will be impossible to continue to feed the milling machine. At this time, since the ingot protection mechanism cannot move the stopped ingot, the operator needs to use tools to hold the stopped ingot and turn it over to the conveyor roller. The process of manually turning over the ingot is time-consuming and labor-intensive, delaying the feeding of the milling machine and affecting the pinning and milling efficiency of the milling machine.

[0025] The embodiment of the present application provides a billet shifting mechanism and system, which are used to solve the technical problem that the traditional billet guarding mechanism can only prevent the billet from rolling down but cannot move the billet remaining on the material storage table. The billet shifting mechanism is provided to move the billet so that the billet rolls down onto the conveyor roller in an orderly manner, effectively preventing the billet from being retained when rolling down, thereby ensuring the normal loading of the milling machine and improving the milling efficiency of the milling machine.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] See also Figure 3 , which is a schematic diagram of the structure of the billet transfer mechanism described in an embodiment of the present invention.

[0028] As shown in the figure, the material storage platform 10 is set between the billet traction device 20 and the conveyor roller 30, and a billet guard assembly 40 is arranged below the connection between the material storage platform 10 and the conveyor roller 30, and a billet shifting mechanism 50 is arranged above the connection between the material storage platform 10 and the conveyor roller 30. The billet shifting mechanism 50 is used to shift the billet on the material storage platform 10; the billet guard assembly 40 is used when the billet shifting mechanism 50 fails, and can block the billet to ensure that the billet does not roll onto the conveyor roller 30 too much.

[0029] The billet feeding mechanism described in the embodiment of the present application includes a base 51 and a feeding machine 52; the base 51 includes a base 511 and a cantilever 512 installed on the base 511; the feeding machine 52 is installed on the cantilever 512 and is located above the material storage table; the feeding machine 52 includes a frame 521, a feeding assembly 522 installed on the frame 521 and a first blocking assembly 523; the feeding assembly 522 contacts the billet on the material storage table to feed the billet, and the first blocking assembly 523 is used to prevent the billet from rolling down. The billet pulled out by the molten casting is first stored on the material storage table. When the milling machine feed signal is received, the billet feeding mechanism feeds the billet to roll down to the conveyor roller through the feeding assembly 522. During the rolling process of the billet, when a billet rolls down, the first blocking assembly 523 extends downward in time to block the subsequent billets that continue to roll down, so that the billet rolls down to the conveyor roller in an orderly and controllable manner to wait for feeding.

[0030] Specifically, the structure of the billet transfer mechanism is described in detail below.

[0031] The base 51 includes a pedestal 511 arranged on the outer side of the conveyor roller, and a cantilever support 513 is arranged above the pedestal 511; a mounting shaft is arranged on the upper part of the cantilever support 513, and the cantilever 512 is movably mounted on the mounting shaft and can rotate up and down around the cantilever support 513; the cantilever 512 extends from the outer side of the conveyor roller toward the material storage platform, and the ingot feeder 52 is located directly above the ingot.

[0032] In order to facilitate installation and maintenance, a feeder positioning assembly 514 is also provided on the base 51; the feeder positioning assembly 514 includes mutually matching positioning pins and positioning holes; the positioning pin is arranged on one end of the cantilever support 513 close to the base 511; the positioning hole is arranged on the outer wall of the upper end of the base 511; when the positioning pin is aligned with the positioning hole, the ingot feeder 52 is located directly above the end of the material storage table close to the conveyor roller to prevent the ingot feeder 52 from shaking during the feeding process.

[0033] Furthermore, a cylinder mounting groove is also provided on the base 511, in which a lifting cylinder 515 is installed; the cantilever support 513 is connected to the piston rod of the lifting cylinder 515, and the cantilever support 513 drives the cantilever 512 and the material feeding machine 52 to rise or fall under the drive of the lifting cylinder 515.

[0034] During installation, when the feeder 52 is located above the billet on the material storage table, the positioning pin is inserted into the positioning hole to ensure that the billet feeder can be located directly above the billet for easy feeding. At this time, the lifting cylinder 515 is retracted to its original position. When the billet feeder 52 needs to be repaired, the positioning pin can be removed, and the cantilever support 513 can be lifted by the lifting cylinder 515, so that the billet feeder can be removed from the billet on the material storage table, and the billet feeder 52 can be rotated to the outside of the material storage table for easy maintenance. After the maintenance is completed, the cantilever support 513 is rotated so that the positioning pin is aligned with the positioning hole, the lifting cylinder 515 is retracted to its original position, and the positioning pin is inserted into the positioning hole to achieve the positioning of the billet feeder 52.

[0035] In this embodiment, the material shifting machine 52 includes a frame 521 , a material shifting assembly 522 disposed on the frame 521 , and a first blocking assembly 523 .

[0036] The frame 521 is mounted on the cantilever 512 via a rotating shaft and is located above one end of the material storage platform close to the conveyor roller. Fixing bolts are also provided on both sides of the rotating shaft on the cantilever 512. The fixing bolts press the frame of the material diverter downward. Before use, the frame 521 is rotated via the rotating shaft to correct the position of the frame 521 so that the frame 521 is located directly above one end of the material storage platform close to the conveyor roller, so that the material diverter assembly can be perpendicular to the placement direction of the ingot.

[0037] The material shifting assembly 522 is installed on the frame 521 and contacts the ingot on the material storage table to shift the ingot. In this embodiment, the material shifting assembly 522 includes a driving motor, a driving wheel, a driven wheel, a belt and a clamping assembly installed on the frame 521; the driving wheel is connected to the output shaft of the driving motor; the belt is wound around the driving wheel and the driven wheel and contacts the ingot on the material storage table; the clamping assembly is located between the driving wheel and the driven wheel, and presses downward to make the belt and the ingot in close contact; the driving motor drives the belt to transmit in the direction of the conveying roller through the driving wheel and the driven wheel, and the belt shifts the ingot under the action of the clamping assembly.

[0038] In an optional embodiment, the clamping assembly may be a flat roller assembly, which is mounted on the frame 521 via a screw. Using a flat roller assembly as a tensioning assembly for the belt can provide better contact between the belt and the billet, making it easier to push the billet to roll downward. The function of the clamping assembly is not limited, and other structural arrangements may also be used in other embodiments.

[0039] Furthermore, the driving motor is a servo motor. Since the servo motor can calculate its output, the use of the servo motor as a belt drive can accurately control the distance of the belt drive.

[0040] The first blocking assembly 523 is installed on the frame 521 and is located above the connection between the material storage table and the conveyor roller, and is used to cooperate with the material shifting assembly to make the billet roll onto the conveyor roller in an orderly and controllable manner. The first blocking assembly 523 includes a first cylinder and a first positioning block; the first positioning block is connected to the piston rod of the first cylinder; the first cylinder drives the first positioning block to extend downward or retract. When the billet is moved onto the conveyor roller by the material shifting assembly 522, the first positioning block extends downward under the push of the first cylinder to block the subsequent billet from rolling down. The driving pulse of the servo motor can accurately control the transmission distance of the belt. When the transmission distance of the belt is the circumference of a billet, the driving motor is controlled to stop rotating. At this time, the first positioning block extends downward and is stuck at the connection between the material storage table and the conveyor roller to block the subsequent second billet from rolling onto the conveyor roller. When the billet on the conveyor roller is transported forward, the first cylinder retracts, driving the first positioning block to retract, and the servo motor runs at the same time, and the next billet is rolled down by the belt shifting. As a result, the ingots can be rolled down one by one in an orderly and controllable manner, effectively preventing too many ingots from rolling down onto the conveying roller.

[0041] Furthermore, in order to prevent excessive castings from rolling under the belt of the material feeder 52, a second blocking assembly 524 is further provided on the frame 521 of the material feeder 52. The second blocking assembly 524 is located above the middle of the material storage table, and includes a second cylinder and a second positioning block; the second positioning block is connected to the piston rod of the second cylinder; the second cylinder drives the second positioning block to extend or retract downward to prevent excessive castings from rolling under the belt and prevent the castings from piling up.

[0042] In an optional embodiment, the ingot material transfer mechanism further includes an ingot guard assembly 40. The ingot guard assembly 40 is arranged below the connection between the material storage platform and the conveyor roller; the ingot guard assembly 40 includes a bracket, a guard cylinder, a rotating arm, a first blocking rod and a second blocking rod; the bracket is arranged on the conveyor roller and extends toward the material storage platform, and the bracket is provided with a first guide sleeve and a second guide sleeve along the rolling direction of the ingot; the guard cylinder is installed on the outer side of the conveyor roller and is located below the bracket; the rotating arm is axially connected to the guard cylinder through a connecting shaft; the first blocking rod and the second blocking rod are respectively hinged to the rotating arm through a first connecting rod and a second connecting rod, and the first blocking rod and the second blocking rod are respectively extended or retracted from the first guide sleeve and the second guide sleeve under the drive of the guard cylinder. When the feeder on the billet feeder mechanism fails, the billet guard assembly can be used temporarily to guard the billet, so that the billet slides down to the conveyor roller under its own gravity. During the sliding process, the billet can be separated by the first blocking rod and the second blocking rod, so that the billets roll down one by one in an orderly manner. In this way, when the feeder fails, the billet can be continuously fed, and the milling machine can continuously mill the billet, reducing the loss of benefits caused by the faulty equipment.

[0043] In other embodiments, the ingot material transfer mechanism may not include the ingot guard assembly. In addition, the structure of the ingot guard assembly is not limited, and may adopt the structure of the original ingot guard mechanism or other structural arrangements.

[0044] In the process of transferring the billet from the material storage table to the conveyor roller, since the material storage table is set up between the billet traction mechanism and the conveyor roller and is inclined at a certain angle toward the conveyor roller, the billet will roll toward the conveyor roller under the action of its own gravity. During the traction process, some billets will bend or have other appearance defects that make it impossible for the billet to roll down automatically, and the billet will stay on the material storage table. If the billet material transfer mechanism in this embodiment is used, a certain amount of power can be applied to the billet, so that the bent or abnormal billet can also roll down to the conveyor roller.

[0045] The following is an explanation of the operating principle of the billet transfer mechanism described in this embodiment.

[0046] The driving motor of the billet feeder drives the billet to roll through the belt transmission, and the belt becomes tense when subjected to the pressure of the compacting flat roller, so that the friction between the belt and the billet continues to increase, thereby driving the billet to roll down. When the driving motor drives the belt to transmit the circumference of a billet, the driving motor stops running, and the first blocking rod is pushed downward by the cylinder and stuck in the connection between the material storage table and the conveying roller to prevent the subsequent billet from continuing to roll down. When the first billet that rolls down to the conveying roller is transported away, the driving motor continues to run, the first blocking rod is retracted, and the second billet rolls down to the conveying roller to wait for transportation. In this way, the problem that the original billet guard mechanism cannot move the billet is solved, so that the billet rolls down to the conveying roller in an orderly and controllable manner to wait for transportation, thereby realizing the stable feeding of the milling machine and ensuring the pin milling efficiency. At the same time, the billet feeder also prevents too many billets from rolling down to the bottom of the belt of the feeder through the second blocking rod. In addition, when the feeder fails, the billet guard assembly can be used to limit the continuously rolling billets, so that the billets roll down to the conveyor roller in an orderly manner, ensuring the loading of the milling machine and reducing the impact caused by equipment failure.

[0047] In addition, an embodiment of the present invention further provides a billet feeding system, comprising a plurality of billet feeding mechanisms as described above, which are sequentially arranged along the billet conveying roller; the belts of the plurality of billet feeding mechanisms are respectively in contact with the various sections of the billet on the material storage table to adjust the placement and rolling direction of the billet. Specifically, in one embodiment, three billet feeding mechanisms can be sequentially arranged along the billet conveying roller, and the belts of the three billet feeding mechanisms act on the front and rear ends and the middle of the billet respectively, and can simultaneously apply force to the billet to drive the billet to roll in the direction of the conveying roller, so as to avoid the phenomenon of asynchronous rolling of the front and rear ends of the billet, thereby ensuring the straightness of the billet and thus ensuring the billet feeding efficiency.

[0048] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
