Description

Technical Field

[0001] The utility model relates to a sawing device, in particular to a runner sawing device for processing aluminum frames, belonging to the technical field of frame processing. Background Art

[0002] After the aluminum frame is integrally cast, the aluminum liquid in the mold runner will solidify on the outside of the frame. Therefore, after the mold is opened, the excess waste at the runner needs to be sawed off. In the prior art, such as the utility model with the application number 202320137293.2, a runner follow-up sawing device for bent pipe castings is disclosed. In order to solve the problems that it is not easy to control by manual rotation, the scrap rate of the casting sawed to the body has always been very high, and the sawing residue is inconsistent. When the residue of individual castings is too high, it will cause the tool to hit the tool and stop during machining, resulting in safety risks. Through the cooperation of the positioning plate and the guide groove, the saw blade can perform runner sawing along the preset cutting trajectory, realizing the unity of the sawing residue of the bent pipe casting, avoiding the risk of tool hitting due to excessive allowance during processing, and no longer sawing and damaging the casting body to cause scrapping.

[0003] The current situation similar to the above application still has deficiencies:

[0004] In order to improve the injection rate of the aluminum liquid, there are multiple groups of runners on the casting mold. During the sawing process, the excess waste at the runner cannot be clamped. After being cut off, the waste will automatically fall off, which is likely to interfere with the movement and sawing of the sawing assembly, and the collection of the waste is inconvenient;

[0005] Therefore, a runner sawing device for processing aluminum frames is designed to optimize the above problems. Summary of the Utility Model

In addition, after all the runner plates are cut off, the runner plates can be uniformly removed and collected, with higher practicability. By arranging a fixing structure composed of a first cylinder, a rotary motor, and a pressing plate on the top of the support table, the frame is positioned by the downward pressing and fixing method, which is not only stable in installation but also more convenient to disassemble.

[0025] Overall working principle: During processing, first place the vehicle frame 3 on the top of the support platform 2, bring the runner plate 4 on the vehicle frame 3 close to the clamping mechanism 6, then use the fixing mechanism 5 to fix the position of the vehicle frame 3, and then use the clamping mechanism 6 to clamp and fix the runner plate 4. Finally, the sawing mechanism moves along the outer surface of the vehicle frame 3 to cut off the runner plate 4. Due to the positioning effect of the clamping mechanism 6 on the runner plate 4, the runner plate 4 will not fall directly, ensuring the stable progress of sawing.

[0026] In this embodiment, the sawing mechanism includes a guide groove 7, a mounting plate 8, and a reciprocating saw 9. The guide groove 7 is opened on the top of the base 1, and the shape of the guide groove 7 is the same as the shape of the side of the vehicle frame 3. An installation plate 8 is slidably provided in the guide groove 7 along the length direction of the guide groove 7, and a reciprocating saw 9 is installed on the top of the installation plate 8.

[0027] Local working principle: During the sawing process of the runner plate 4, the reciprocating saw 9 is started, and then the mounting plate 8 moves along the length direction of the guide groove 7. The saw blade of the reciprocating saw 9 moves along the outer side of the vehicle frame 3, ensuring the sawing effect of the runner plate 4 and not damaging the vehicle frame 3.

[0028] In this embodiment, the fixing mechanism 5 includes a first cylinder 10, a rotary motor 11 and a pressing plate 12. The first cylinders 10 are vertically installed at both ends of the top of the support table 2. The output ends of the first cylinders 10 are both equipped with rotary motors 11, and the output ends of the rotary motors 11 are both equipped with pressing plates 12. And the middle position at the bottom of the pressing plate 12 is connected to the output shaft of the rotary motor 11.

[0029] Local working principle: Before placing the vehicle frame 3, start the rotary motor 11 to align the two pressing plates 12 in the same straight line, then place the vehicle frame 3 on the top of the support table 2. The pressing plates 12 pass through the inside of the vehicle frame 3, then control the pressing plates 12 to rotate 90 degrees, and then start the first cylinder 10 to control the downward movement of the pressing plates 12 to press and fix the vehicle frame 3.

[0030] In this embodiment, a rubber pad is provided at the bottom of the pressing plate 12, and anti-slip lines are provided at the bottom of the rubber pad.

[0031] Local working principle: The use of the rubber pad at the bottom of the pressing plate 12 can prevent the vehicle frame 3 from being squeezed and deformed.

Third cylinders 17 are installed on the tops of the U-shaped plates 16, and the output ends of the third cylinders 17 all extend into the inside of the U-shaped plates 16.

[0033] Local working principle: After the position of the vehicle frame 3 is fixed, start the second cylinder 14 to control the cross plate 15 to move towards the vehicle frame 3. The runner plate 4 enters the inside of the U-shaped plate 16, and then start the third cylinder 17 to fix the runner plate 4 inside the U-shaped plate 16 to stabilize the position of the runner plate 4.

[0034] In this embodiment, push plates 18 are slidably installed inside the U-shaped plates 16, and return springs 19 are provided between the sides of the push plates 18 and the inner ends of the U-shaped plates 16.

[0035] Local working principle: When the runner plate 4 is fixed, the push plate 18 will be extruded towards the inside of the C-shaped plate 16, and the return spring 19 is in a compressed state. After the sawing is completed, after releasing the fixing state of the runner plate 4, the return spring 19 will push the push plate 18 to reset, so as to push out the runner plate 4, making it more convenient to take out.

[0036] In this embodiment, a storage groove is provided at the top of the base 1 and below the cross plate 15.
