Description

Technical Field

[0001] The utility model belongs to the technical field of up-drawing oxygen-free copper rods, and particularly relates to a special grinding device for up-drawing oxygen-free copper rods. Background Art

[0002] The up-drawing oxygen-free copper rod, also known as the oxygen-free copper rod, is a high-purity copper material with extremely low oxygen content, usually below 20 ppm, or even lower.

[0003] For example, the Chinese patent with the publication number CN219704413U discloses a grinding device for high-precision low-oxygen copper rods, including a bottom plate. A rotating member is arranged on one side of the bottom plate, and the rotating member includes a side plate, and a motor is fixedly connected to one side of the side plate. The advantages of the utility model are as follows: Turn on the electric cylinder to drive the limiting plate to move until the copper rod moves into the rotating ring. Multiple copper rods can be fixed in one grinding operation. At this time, the grinding plate is pressed against the copper rod by the spring. Then turn on the motor to drive the driving gear to rotate. Through meshing transmission, several driven gears can be driven to rotate, and then several copper rods can be driven to rotate synchronously. Then turn on the electric slide rail to drive the grinding frame to move left and right reciprocally. The copper rod can be ground through the abrasive grinding groove, and multiple copper rods can be ground in one operation, which can greatly improve the efficiency of the grinding operation.

[0004] The above patent has the following problems:

[0005] There are some disadvantages in the use of the above patent. For example, the above device lacks the function of replacing the grinding plate. After long-term use, the grinding plate will gradually wear. If it is not replaced in time, it will directly lead to a significant decline in the grinding effect. At the same time, when the above device is in use, the copper rod may be bent, resulting in the bent part of the copper rod not being well ground during grinding. In view of this, we propose a special grinding device for up-drawing oxygen-free copper rods. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a special grinding device for up-drawing oxygen-free copper rods to solve the problems put forward in the above background art.

[0012] In this technical solution, when it is necessary to grind the up-drawn oxygen-free copper rod, the operator first inserts one end of a plurality of up-drawn oxygen-free copper rods into a plurality of rotating frames on one of the sliding plates respectively. Subsequently, the operator rotates a plurality of threaded columns on one of the sliding plates respectively. Under the action of the thread, the threaded column drives the corresponding clamping block two to slide downward. The plurality of clamping block twos and the plurality of clamping block ones on one of the sliding plates can fix one end of the up-drawn oxygen-free copper rod. Through the arranged driving assembly, the two sliding plates can be driven to slide and approach each other. Subsequently, the other end of the up-drawn oxygen-free copper rod is inserted into a plurality of rotating frames on the other sliding plate, and the other end of the up-drawn oxygen-free copper rod can be fixed through the above operation. Through the arranged driving assembly, the two sliding plates can be driven to slide and move away from each other. Subsequently, a plurality of up-drawn oxygen-free copper rods will be stretched and no longer bent. When the stretching of the up-drawn oxygen-free copper rod is completed, the operator starts the two electric sliding rails. Subsequently, the sliding frame will slide back and forth. The sliding frame drives the grinding plate to slide. At the same time, under the action of the tension of a plurality of tension springs, a plurality of sliding columns all slide upward. The plurality of sliding columns squeeze the fixing strip and the grinding plate to slide upward. The grinding plate will be in close contact with a plurality of up-drawn oxygen-free copper rods.

Then the operator rotates a number of threaded posts on one of the sliding plates respectively. Under the action of the thread, the threaded posts drive the corresponding clamping blocks II to slide downward. A number of clamping blocks II on one of the sliding plates and a number of clamping blocks I can fix one end of the up-drawn oxygen-free copper rod.

Then the operator rotates the threaded rod reversely. Under the action of the thread, the threaded rod drives the two sliding plates to slide and move away from each other. Then a number of up-drawn oxygen-free copper rods will be stretched and no longer bent. After the up-drawn oxygen-free copper rod is stretched, the operator starts two electric slide rails. Then the sliding frame will slide reciprocally. The sliding frame drives the grinding plate to slide. At the same time, under the pulling force of a number of tension springs, a number of sliding columns all slide upward. A number of sliding columns squeeze the fixing bar and the grinding plate to slide upward. The grinding plate will be in close contact with a number of up-drawn oxygen-free copper rods. Finally, the operator starts the motor. The motor is powered on and drives the worm to rotate. The worm drives a number of worm wheels meshing with it to rotate.

[0080] Working principle: When it is necessary to grind the up-drawn oxygen-free copper rod, the operator first inserts one end of several up-drawn oxygen-free copper rods into several rotating frames 4 on one of the sliding plates 3 respectively. Then the operator rotates several threaded columns 7 on one of the sliding plates 3 respectively. Under the action of the thread, the threaded columns 7 drive the corresponding second clamping blocks 6 to slide downward. Several second clamping blocks 6 and several first clamping blocks 5 on one of the sliding plates 3 can fix one end of the up-drawn oxygen-free copper rod. Then the operator rotates the threaded rod 14 forward. Under the action of the thread, the threaded rod 14 drives the two sliding plates 3 to slide and approach each other. Then the other end of the up-drawn oxygen-free copper rod is inserted into several rotating frames 4 on the other sliding plate 3, and the other end of the up-drawn oxygen-free copper rod can be fixed through the above operations. Then the operator rotates the threaded rod 14 in the reverse direction. Under the action of the thread, the threaded rod 14 drives the two sliding plates 3 to slide and move away from each other. Then several up-drawn oxygen-free copper rods will be stretched and no longer bent. After the up-drawn oxygen-free copper rod is stretched, the operator starts the two electric slide rails 8. Then the sliding frame 9 will slide back and forth. The sliding frame 9 drives the grinding plate 13 to slide. At the same time, under the pulling force of several tension springs 12, several sliding columns 10 all slide upward. Several sliding columns 10 squeeze the fixing strip 11 and the grinding plate 13 to slide upward. The grinding plate 13 will be in close contact with several up-drawn oxygen-free copper rods. Finally, the operator starts the motor 17. The motor 17 is powered on and works to drive the worm 18 to rotate. The worm 18 drives several worm wheels 16 meshed with it to rotate. Several worm wheels 16 respectively drive the corresponding rotating frames 4 to rotate. Several rotating frames 4 respectively drive several up-drawn oxygen-free copper rods to rotate. At the same time, under the sliding action of the grinding plate 13, the up-drawn oxygen-free copper rod will be evenly ground;

[0081] When it is necessary to replace the grinding plate 13, the operator first presses the two limiting strips 20 to slide and approach each other. At the same time, several springs 21 are compressed and contracted. When the two limiting strips 20 slide to the appropriate position, the operator can take out the grinding plate 13 upward. Then place a new grinding plate 13 on the top of the fixing strip 11. Then both of the two limiting strips 20 are inserted into the new grinding plate 13. Finally, the operator releases the two limiting strips 20. Under the rebounding force of several springs 21, the two limiting strips 20 slide and move away from each other. Then the upper ends of the two limiting strips 20 are limited in the grinding plate 13, and further the position of the new grinding plate 13 can be fixed, which is convenient for the operator to replace the grinding plate 13 and no tools are required.
