Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casting, in particular to a gate cutting device for casting a gear box. Background Art
[0002] During the casting process, the gear box body needs to be produced by pouring casting, and the gate is a channel from the branch channel to the mold cavity during the pouring process, that is, the feed port of the pouring material. During the casting process, the molten metal needs to be poured into the mold cavity through the gate. After the molten metal cools down, an excess part will be generated at the gate, that is, the pouring riser. The excess part is the part other than the shape and specifications of the workpiece itself, and it needs to be cut off after pouring.
[0003] Existing methods for cutting gates include: 1. Shearing with pliers, scissors, etc.; 2. Shot blasting and sand blasting; 3. Milling and planing. It is laborious to cut with pliers and scissors, and shot blasting and sand blasting will reduce the aesthetics. The processing costs of milling and planing are high. These shearing methods cannot smooth the cuts at the same time. In the process of cutting the gate with a cutting machine and then smoothing the cut with a grinder alone, a large amount of flying dust will be generated, which will affect the environment in the workshop. The flying dust will be inhaled by the workers and will also affect the workers' health. Utility Model Content

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0021] Embodiment 1
[0022] like Figure 1 , Figure 2 and Figure 5 As shown, a gate cutting device for gear box casting includes a circular plate 1 and a cutting and grinding structure. The circular plate 1 is provided with a handle 2, and the handle 2 is provided with a grip rod 3. A rubber sleeve is adhered to the grip rod 3 to facilitate the taking and manipulation of the circular plate 1. A suction pipe 4 is provided on one side of the circular plate 1. The circular plate 1 is provided with at least one dust suction port 5 that is evenly arranged in a ring shape. The dust suction ports 5 are all plugged with rubber plugs. When not in use, the rubber plugs are plugged into the dust suction ports 5. The circular plate 1 is provided with a confluence pipe connected to the suction pipe 4 and each dust suction port 5.
[0023] Through the above structure, the flying dust can be sucked away. How to polish the incision during the cutting process? The specific structure is as follows:
[0024] like Figure 1 , Figure 3 and Figure 4 As shown, a groove 6 is provided in the circular plate 1, a driving motor 7 is provided in the groove 6, the cutting and grinding structure includes a cutting disc 9, a shaft 8 connected to the output end of the driving motor 7 is fixedly connected to the cutting disc 9, a grinding disc 11 is provided on the cutting disc 9, and a control button electrically connected to the driving motor 7 is provided on the circular plate 1 to facilitate the control of the switch of the driving motor.
[0025] With the above structure, when the moving cutting disc 9 cuts the gate, the grinding disc 11 can be used to grind the cut.
[0026] Embodiment 2
[0027] like Figure 3 and Figure 4 As shown, the grinding disc 11 is fixedly connected with relatively arranged threaded columns 12, and the cutting disc 9 is provided with relatively arranged connecting holes 10 respectively matched with the threaded columns 12 on both sides, and the threaded columns 12 are fixed in the connecting holes 10 by nuts.
[0028] Through the above structure, the grinding disc 11 can be replaced.
[0029] During the specific implementation of the utility model, when it is necessary to cut the gate, the worker holds the handle on the handle to control the position of the circular plate, and turns on the driving motor at the same time. The driving motor can drive the shaft, the cutting disc and the grinding disc to rotate at high speed at the same time, and the gate can be cut by the cutting disc. At the same time, in the process of moving the cutting disc, the grinding disc can contact the cut just made, so that the cut can be polished during cutting;
[0030] A lot of flying dust will be generated during the cutting and grinding process. At this time, turn on the suction pump, and the flying dust will be sucked into the suction pump through the dust suction port, the confluence pipe and the suction pipe. This can suction the flying dust and prevent it from affecting the environment in the factory and the health of the workers. When the grinding disc needs to be replaced, unscrew the nut and remove the threaded column from the connecting hole, so that the grinding disc can be removed and replaced with a new one.
