DETAILED DESCRIPTION

[0020] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 4 As shown, a cold pressing device for diamond fine grinding discs includes a conveyor line 1, on which a filler 2, a cold press machine 3 and a discharger 4 are sequentially arranged along the conveying direction, and a mold slot 5 is constructed on the conveyor line 1, and a cold pressing mold 6 is arranged in the mold slot 5. Among them, the filler 2, the cold press machine 3, the discharger 4 and the connection relationship between the mold slot 5 and the cold pressing mold 6 are all prior art, for example, they have been disclosed in the patent with the announcement number CN214642914U, and the connection relationship between the filler 2, the cold press machine 3, the discharger 4 and the mold slot 5 and the cold pressing mold 6 in the above patent is incorporated into this disclosure by reference. In short, the filler 2 can fill the abrasive in the cold pressing mold 6, and then under the transportation of the conveyor line 1, the cold pressing mold 6 enters the cold press machine 3 station, and the punch of the cold press machine 3 extends into the cold pressing mold 6 to realize the cold pressing of the grinding disc, and then the grinding disc can be discharged through the discharger 4.

[0022] Specifically, the cold pressing mold 6 includes a base 7, a cold pressing groove 8 is provided on the base 7, and a bottom cover 9 capable of covering the cold pressing groove 8 is rotatably provided at the bottom of the base 7. Among them, the cooperation method of the bottom cover 9 and the base 7 is disclosed in the above-mentioned patent, so it is not repeated here. In order to realize the rapid adjustment of the cold pressing mold 6 when the cold pressing size of the grinding sheet changes, in the present disclosure, a cold pressing cylinder 10 is detachably provided in the cold pressing groove 8, so that a cold pressing cavity 11 will be formed between the bottom cover 9 and the cold pressing cylinder 10 by covering the cold pressing groove 8 with the bottom cover 9. More specifically, the cold pressing cylinder 10 and the base 7 are locked or released by a locking assembly 12, and a disassembly assembly 13 and an installation assembly 14 are also engaged on the conveyor line 1.

[0023] In some embodiments, the cold pressing cylinder 10 preferably includes a receiving portion 16 and a cold pressing portion 17 connected from top to bottom, and the cross-sectional area of ​​the receiving portion 16 gradually decreases toward the cold pressing portion 17. For example, the receiving portion 16 can facilitate the filling of the cold pressing cavity 11 by the filler 2, and can also facilitate the punch to enter the cold pressing cavity 11 for punching.

[0024] For example, the locking assembly 12 may preferably include an electromagnet 18 embedded in the side wall of the cold pressing groove 8, and correspondingly at least the cold pressing portion 17 of the cold pressing cylinder 10 is made of magnetic material. Therefore, when the electromagnet 18 is energized, the electromagnet 18 can absorb the cold pressing portion 17 to achieve a locking action; when the electromagnet 18 is de-energized, the cold pressing portion 17 can freely escape from the cold pressing groove 8 to achieve a releasing action.

[0025] In a preferred example, the disassembly assembly 13 includes a movably arranged first connecting frame 19, and a disassembly groove 20 is constructed on the first connecting frame 19. For example, the first connecting frame 19 as a whole includes a receiving end 24 and a storage end connected to each other, and the receiving end 24 of the first connecting frame 19 is arranged obliquely. When the above-mentioned locking assembly 12 unlocks the cold pressing cylinder 10, the first connecting frame 19 can be moved to the top of the conveyor line 1, and as the conveyor line 1 conveys the cold pressing mold 6, the conveyor line 1 can drive the receiving part 16 of the cold pressing cylinder 10 into the disassembly groove 20, and under the oblique guidance of the receiving end 24, the cold pressing part 17 can gradually escape from the cold pressing groove 8, and as the subsequent cold pressing cylinder 10 is stuck in the disassembly groove 20, a number of cold pressing cylinders 10 can be pushed to be stored in the storage end to complete the disassembly action.

[0026] The installation assembly 14 may preferably include a second mobile frame 21. For example, the second mobile frame 21 may include a storage end and a discharge end 25 arranged from high to low as a whole, and a discharge trough 22 similar to the above-mentioned disassembly trough 20 may be constructed on the second mobile frame 21, and a number of cold press cylinders 10 to be replaced may be hung on the discharge trough 22 through the receiving portion 16. In addition, a stopper is rotatably provided on the discharge end 25, and the stopper can limit the cold press cylinder 10 from falling to one side of the conveyor line 1 through the stopper, and when the stopper end is opposite to the cold press trough 8, the stopper can be driven by the driving member to rotate from the stopper position to the discharge position, at which time the end of the discharge trough 22 is opened, and the cold press cylinder 10 to be replaced can fall into the cold press trough 8 to realize the installation and replacement action.

[0027] For example, the top of the cold pressing groove 8 is constructed with a guide notch, through which the cold pressing cylinder 10 that is about to fall into the cold pressing groove 8 can be guided; in addition, it is also preferred that a limiting plate 15 is provided on the side wall of the cold pressing cylinder 10, when the cold pressing cylinder 10 falls into the cold pressing groove 8, the limiting plate 15 can abut against the top surface of the base 7 to limit the installation position of the cold pressing part 17 in the cold pressing groove 8, for example, the fitting part between the bottom cover 9 and the bottom surface of the cold pressing part 17 can be improved, thereby ensuring the accuracy of the grinding disc produced by cold pressing.

[0028] In some embodiments, the conveyor line 1 may preferably be an annular conveyor line 1, for example, the annular conveyor line 1 may be an annular conveyor belt, a mold groove 5 is provided on the annular conveyor belt, and the cold pressing mold is installed in the mold groove 5. Therefore, one side of the annular conveyor line 1 may be a working side, and the other side may be an installation side, the second mobile frame 21 may be engaged with the installation side, and the first mobile frame may be moved into the upper part of the working side to realize the removal of the cold pressing cylinder 10.

[0029] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
