Description

Technical Field

[0001] The utility model relates to the technical field of unloading fixtures, in particular to a unloading fixture for vanadium-nitrogen alloy finished products. Background Art

[0002] Vanadium-nitrogen alloy is a new type of alloy additive that can replace ferrovanadium in the production of micro-alloyed steel. When sintering in a push-plate kiln, the vanadium-nitrogen alloy needs to be placed in a graphite crucible and forms a block after sintering.

[0003] However, in order to improve the unloading efficiency of the vanadium-nitrogen alloy finished products, some technologies have proposed related structures to assist in the unloading of the vanadium-nitrogen alloy finished products. For example, there is a utility model patent with the publication number CN210794924U, which proposes an unloading clamp for the vanadium-nitrogen alloy finished products. When the output end of the clamping cylinder drives the lifting plate to descend, the push-pull rod is pushed to move by the pressure rod, and then the corresponding clamping block is moved toward the center of the mounting cylinder by the respective push-pull rods until the clamping plate touches the surface of the crucible, completing the unloading process. By clamping the crucible, the vanadium-nitrogen alloy finished product in the crucible is indirectly clamped, thereby achieving the purpose of facilitating clamping.

[0004] From the above disclosed technical content, theoretically speaking, the implementation of the relevant technical structure is conducive to the clamping of vanadium-nitrogen alloy products, but as the time and usage of the splint and the crucible continue to increase, the splint will be worn, and the degree of wear will continue to increase and the wear area will continue to expand. The worn splint will reduce the effect of clamping the crucible. In the above disclosed technical content, the splint is installed on the clamping block in a fixed connection manner. When the worn splint needs to be replaced, the fixed connection method will increase the difficulty of replacing the splint.

[0028] See also Figure 4 and Figure 5 The moving component 9 includes a ball screw 901, and the outer wall of the ball screw 901 is threadedly connected to a ball nut 902. The threaded connection method enables the circumferential rotation of the ball screw 901 to provide power for the horizontal movement of the ball nut 902. The outer end of the ball screw 901 is fixedly mounted with a rotating motor 20 located outside the limit component 10, and a reducer is provided on the output shaft of the rotating motor 20.

[0029] The limit assembly 10 is composed of a limit gear 101 and a limit block 102. When the limit gear 101 and the limit block 102 are separated, the moving assembly 9 can move.

[0030] Working principle: When in use, first, the height of the frame 11 can be adjusted by utilizing the telescopic movement of the internal output shaft of the No. 1 electric push rod 13, and then the horizontal movement of the frame 11 can be realized by utilizing the setting of the electric slide rail 14. Then, the power supply of the No. 2 electric push rod 22 is turned on, and the retraction of the internal output shaft of the No. 2 electric push rod 22 is utilized to separate the limit gear 101 from the limit block 102. At this time, the power supply of the rotating motor 20 is turned on. After the rotating motor 20 is turned on, it drives the rotation of the ball screw 901. Due to the threaded connection between the ball screw 901 and the ball nut 902, the ball screw 901 rotates in a circular direction while driving the horizontal movement of the ball screw 901. When the ball screw 901 moves, it drives the telescopic movement of the extension rod 7 inside the sleeve rod 8. The movement of the extension rod 7 drives the simultaneous movement of the splint 1 through the connection of the connecting component 4. The clamping block 2 can be adjusted to the desired position by adjusting the direction of movement. Finally, when the clamping plate 1 is worn and affects normal use, due to the threaded connection between the annular block 5 and the locking block 2, the staff holds the protective cover 6 and removes the annular block 5 from the locking block 2 in a rotating manner, and then presses the connecting block 402 to move toward the inside of the fixed block 3. While the connecting block 402 moves, the spring 401 is compressed until the connecting block 402 is separated from the locking block 2. The locking block 2 can then be removed from the fixed block 3, and the worn clamping plate 1 can be replaced. The connecting block 402 can be ejected from the inside of the locking block 2 by utilizing the rebound of the spring 401, so that the connection component 4 and the locking block 2 can be connected, and the new clamping plate 1 can be installed. Then the protective cover 6 is installed so that the protective cover 6 protects the connecting component 4 and prevents the connecting component 4 from being damaged.
