Description

Technical Field

[0001] This utility model relates to the technology of sawing device for casting risers and gating points, specifically an automatic sawing device for automobile castings. Background Technology

[0002] Some automotive parts have gates and risers formed on them after casting. After the casting is formed, it needs to be sawed by a cutting saw to meet the assembly requirements.

[0003] Existing automatic sawing devices for automotive castings require water washing to cool the sawing disc during sawing. Additionally, larger structural components often fall off during sawing. Currently, the common method for collecting these components is a conveyor belt at the bottom of the machine room, which removes them for centralized processing. However, this method has a significant drawback: water generated during sawing also flows down the conveyor belt through the chute, contaminating it. Over time, this shortens the conveyor's lifespan, increases malfunctions, and is time-consuming and labor-intensive to clean. Therefore, we propose an automatic sawing device for automotive castings to address these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an automatic cutting saw device for automobile castings to solve the problems mentioned in the background art.

[0013] Preferably, the drive assembly includes a motor fixed in the mounting slot, a gear fixed at the output end of the motor, a rack fixed on the side of the separation plate near the motor, the rack meshing with the gear, and connecting rods fixed on the left and right sides of the separation plate, one end of the connecting rod being fixedly connected to the adjacent wall of the baffle plate.

[0014] Preferably, the top of the separation plate is provided with an inclined surface, the top of the separation plate is provided with water grooves at equal intervals, and the end of the separation plate near the water collection tank is provided with a number of separation holes.

[0015] Preferably, the outer contour of the separation shell is T-shaped, and a material discharge cavity is provided at the bottom of the separation shell.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By using a separation shell, separation plate, and drive assembly, the structural parts that fall off during the sawing of automotive castings and the cooling water that flows down can be collected in a unified manner. Then, on the separation plate, the cooling water will be discharged through a water tank and collected in a water collection tank through the separation hole. After the water is separated, the structural parts will fall off after the separation plate is removed and enter the conveyor from the drop chute to be transported out of the machine room. This minimizes the problem of contaminating the conveyor when removing the sawing structure, improves the service life of the conveyor structure after long-term use, and also reduces the frequency of cleaning the conveyor belt.

[0018] 2. By using the drive assembly and the separation plate together, it is easy to continue to block the top of the separation shell after the separation plate is removed, thus preventing external cooling water from entering the separation shell after the separation plate is opened, and further ensuring the blocking effect of cooling water.

The lower sliding grooves 8 and upper sliding grooves 7 are used to guide the separating plate 9 and the baffle plate 10, respectively.

[0033] Separation plate 9 is slidably connected in the sliding groove 8. Separation plate 9 is used to separate the water flow from the structural components after cutting and sawing, so as to prevent the water flow from corroding the conveyor below.

[0034] The baffle plate 10 is slidably connected in the upper sliding groove 7. The baffle plate 10 is used to provide auxiliary protection above the separation shell 4 when the separation plate 9 is removed from the separation shell 4, so as to prevent subsequent water from entering the separation shell 4 and improve the intervention of water.

[0035] Water collection tank 14 is detachably connected to one end of separation plate 9. Water collection tank 14 is used to collect water flowing out of separation plate 9. A collection trough is provided on the side of water collection tank 14 near separation plate 9. A drain valve is provided at the bottom of water collection tank 14 to drain internal water.

[0036] In this embodiment, the driving assembly includes a motor 11 fixed in the mounting groove 5, a gear 12 fixed at the output end of the motor 11, a rack 13 fixed on the side of the separation plate 9 near the motor 11, the rack 13 meshing with the gear 12, and connecting rods 15 fixed on the left and right sides of the separation plate 9 respectively. One end of the connecting rod 15 is fixedly connected to the adjacent wall of the baffle plate 10. The motor 11 can drive the separation plate 9 to move in the sliding groove 8 through the meshing of the gear 12 and the rack 13. At the same time, the baffle plate 10 can be synchronously driven to move in the same direction and at the same speed as the separation plate 9 through the connection of the connecting rod 15.

A chamfer is provided at the top of the material dropping cavity to prevent material jamming when cutting and separating structural parts.

[0039] In practical implementation, the following steps are taken: The automotive casting is fixed to the workbench 3 using a fixing assembly. Then, the cutting saw assembly 2 and the workbench 3 are activated to cut the fixed automotive casting. During the cutting process, a water-spraying cooling structure is installed in the machine room 1 to cool the cutting disc. Fallen structural parts during cutting will fall into the separation shell 4 and be blocked by the separation plate 9. Simultaneously, some of the sprayed water will accumulate on the separation plate 9, forming a water flow that flows along the water trough 16 into the water collection tank 14 for collection. After the sawing is completed, the controller controls the motor 11 to operate... The mechanism drives the gear 12 to rotate, causing the gear 12 to mesh with the rack 13 and move the separation plate 9 out of the separation shell 4. The structural parts that have been cut and fallen from the automotive castings and accumulated on the separation plate 9 will be blocked by the inner wall of the separation shell 4 and will not be moved out with the separation plate 9. Instead, they will fall down onto the conveyor as the area of ​​the separation plate 9 inside the separation shell 4 decreases and is moved out by the conveyor. As the separation plate 9 moves, it will also drive the baffle plate 10 to re-close the top opening of the separation shell 4 through the connecting rod 15, preventing subsequent cooling water from entering the separation shell 4.
