Description

Technical Field

[0001] The utility model relates to the field of tungsten-molybdenum bar processing, in particular to a tungsten-molybdenum bar cutting device. Background Technique

[0002] After tungsten-molybdenum bars are formed and sintered, in order to be better used, the tungsten-molybdenum bars need to be cut into short bars, so a cutting device is required; for example, the patent document with the publication number CN219684091U discloses a tungsten-molybdenum bar cutting device. By setting a clamping assembly and arranging the clamping assembly close to the support block, the clamping position can be close to the cutting position, so that the tungsten-molybdenum bar will not shift during cutting through the clamping assembly. During the cutting process of the tungsten-molybdenum bar, a large amount of debris will be generated. In the above cutting device, the debris easily falls into the clamping assembly. The accumulation of debris in the clamping assembly will affect its clamping work, and it is relatively inconvenient to clean the debris. Moreover, the debris will splash during the cutting process, posing a certain danger. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0023] The present utility model will be further described below in conjunction with the drawings:

[0024] As Figures 1-6 shown, a tungsten and molybdenum bar cutting device includes a workbench 1. A mounting plate 2 is fixed on the top of the workbench 1. A feeding wheel 3 is rotatably mounted on the front side of the mounting plate 2. The feeding wheel 3 is used for conveying tungsten and molybdenum bars. Two protective boxes 4 are symmetrically distributed up and down on the front side of the mounting plate 2. A cutting mechanism is arranged in the upper protective box 4. The cutting mechanism includes a mounting seat 501. The mounting seat 501 is located in the protective box 4. A motor 502 is fixed to the bottom of the mounting seat 501 by screws. A blade 503 is fixed to the output shaft of the motor 502. The cutting mechanism further includes a lifting assembly for driving the mounting seat 501 to move up and down. The lifting assembly is mounted on the mounting plate 2. An elastic mechanism is arranged on the top of the mounting seat 501. The elastic mechanism is used to drive the mounting seat 501 to drive the protective box 4 to move up and down. A transmission mechanism is arranged on the rear side of the protective box 4. The transmission mechanism is used to make the moving directions of the two protective boxes 4 opposite.

[0025] The lifting assembly includes a cylinder 504 and a fixing plate 505. The fixing plate 505 is welded to the front side of the mounting plate 2. The cylinder 504 is connected to the bottom of the fixing plate 505 by bolts. The output shaft of the cylinder 504 extends into the upper protective box 4 and is fixedly connected to the mounting seat 501. The mounting seat 501 is driven by the cylinder 504 to move downward. The mounting seat 501 drives the upper protective box 4 to move downward through an elastic mechanism. The upper protective box 4 drives the lower protective box 4 to move upward through a transmission mechanism. Finally, the two protective boxes 4 are closed. The two protective boxes 4 clamp the tungsten-molybdenum bar to prevent the tungsten-molybdenum bar from shifting during cutting. Then, the cylinder 504 continues to drive the mounting seat 501 to move downward, causing the elastic mechanism to stretch, and the motor 502 and the blade 503 move downward relative to the protective box 4, thereby cutting the tungsten-molybdenum bar. The chips generated by cutting fall into the lower protective box 4, which not only prevents the chips from splashing but also facilitates the subsequent cleaning of the chips.

[0026] The elastic mechanism includes a fixed sleeve 601. The fixed sleeve 601 is welded to the inner top wall of the upper protective box 4. A movable rod 602 is slidably connected inside the fixed sleeve 601. The bottom end of the movable rod 602 is fixed to the top of the mounting seat 501. A spring 603 is fixedly connected between the fixed sleeve 601 and the movable rod 602. After the two protective boxes 4 are closed, the protective box 4 remains stationary. At this time, the cylinder 504 drives the mounting seat 501 to continue moving downward, causing the movable rod 602 to extend out of the fixed sleeve 601 and the spring 603 to stretch, so as to cut the tungsten-molybdenum bar after the two protective boxes 4 are closed.

[0027] The transmission mechanism includes two limit sliding plates 701 arranged symmetrically up and down. The two limit sliding plates 701 are respectively connected to the two protective boxes 4 by screws. A sliding groove 201 is formed on the mounting plate 2. The limit sliding plate 701 is slidably connected inside the sliding groove 201. A gear 703 is rotatably installed inside the sliding groove 201. A rack 702 is engaged with both the front and rear sides of the gear 703. The two racks 702 are respectively fixedly connected to the two limit sliding plates 701. An avoidance hole 704 for the rack 702 to pass through is formed on the limit sliding plate 701.

[0028] Semicircular grooves are formed on both sides of the protective box 4. A rubber pad 401 is fixed inside the semicircular grooves. When the two protective boxes 4 are closed up and down, the two semicircular grooves are closed to form a circular hole. After the two protective boxes 4 are closed, the tungsten-molybdenum bar passes through the protective box 4 through the circular hole, thus ensuring the sealing performance of the closure of the two protective boxes 4, and the tungsten-molybdenum bar can be prevented from being damaged by setting the rubber pad 401.

[0029] A collection box 8 is slidably connected inside the lower protective box 4. A handle is fixedly connected to the front side of the collection box 8. The chips generated during cutting fall into the collection box 8. The staff can pull out the collection box 8 to clean the chips, which is convenient to use.

[0030] Working principle: When cutting tungsten-molybdenum bars, first, the cylinder 504 drives the mounting seat 501 to move downward. The mounting seat 501 drives the movable rod 602 to move downward. The movable rod 602 drives the fixed sleeve 601 to move downward through the spring 603. The fixed sleeve 601 drives the upper protective box 4 to move downward. The upper protective box 4 drives a limit slide plate 701 and a rack 702 to move downward, causing the gear 703 to rotate. The gear 703 drives another rack 702 to move upward, so that the lower protective box 4 moves upward synchronously. Finally, the two protective boxes 4 are closed. At this time, the tungsten-molybdenum bar is clamped by the rubber pad 401 to prevent the tungsten-molybdenum bar from shifting during cutting. Then, continue to make the cylinder 504 drive the mounting seat 501 to move downward. Since the two protective boxes 4 do not move at this time, the fixed sleeve 601 does not move. Thus, the mounting seat 501 drives the movable rod 602 to move downward, and the spring 603 is stretched. The blade 503 is driven to rotate by the motor 502. As the mounting seat 501 moves downward, the blade 503 cuts the tungsten-molybdenum bar, and the chips generated by cutting fall into the collection box 8.

[0031] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
