Description

Technical Field

[0001] This utility model belongs to the field of parts manufacturing technology and relates to a pneumatic material suction device for material scrap. Background Technology

[0002] Because shavings splashing onto the surface of parts can cause defects such as scratches, resulting in rework, and aluminum parts placed on edges can be scrapped, production line stoppages for shaving cleaning cause numerous downtimes. Statistics across various production lines show that shaving-related downtime accounts for up to 90%, severely impacting production efficiency. Traditional shaving repair methods involve adjusting the perpendicularity of the cutting edge, clearance, engagement depth, and engagement sequence, which can only temporarily eliminate or alleviate the shaving problem. With continuous production, inevitable wear on the cutting edge leads to a recurrence of the shaving problem. Therefore, eliminating persistent shavings and improving production efficiency is of great significance. Traditional methods are inefficient and ineffective. Utility Model Content

[0003] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a pneumatic material suction device for material scrap, which uses compressed air to generate negative pressure to form an adsorption airflow to adsorb material scrap, and the material scrap is then discharged together with the compressed air, resulting in a significant material scrap treatment effect.

[0004] To achieve the above objectives, the technical solution of this utility model is: a pneumatic material suction device for scrap, comprising a valve body, a valve core, and a valve core fixing bolt, all three being hollow structures. The valve body has a main air inlet, and the valve core fixing bolt is installed at the end of the valve body to fix the valve core within the valve body. The valve core has a wedge-shaped channel inside, and also multiple valve core air passages. The centerline of each air passage is parallel to the inner wall of the wedge-shaped channel, connecting the main air inlet and the wedge-shaped channel. Compressed air enters the valve body through the main air inlet, passes through the valve core air passages into the wedge-shaped channel inside the valve core, and finally discharges the collected scrap through the valve core fixing bolt.

[0005] Preferably, the valve core is a hollow stepped shaft structure, which is divided into three parts: a left shaft, a middle shaft, and a right shaft. The outer diameters of the left shaft and the right shaft are equal and larger than the outer diameter of the middle shaft.

[0006] Preferably, the valve core air passage holes are provided with six holes, which are evenly arranged on the left end of the right shaft.

[0007] Preferably, the diameter of the valve core air passage hole is 2mm to 3mm.

[0008] Preferably, the wedge-shaped channel is located inside the right shaft, with its left end diameter being larger than its right end diameter to form a wedge shape.

[0009] Preferably, the valve body is a hollow stepped shaft structure, with internal threads on the inner wall of its right end and external threads on the outer wall of the left end of the valve core fixing bolt, which is screwed into the right end of the valve body and tightens the right end of the valve core.

[0010] Preferably, the intake pressure at the main air intake is 6 bar.

[0011] The pneumatic material suction device for scrap provided by this utility model has the following beneficial effects:

[0012] 1. After the material scrap is collected, it is discharged to the waste port of the press. No maintenance is required, ensuring that the negative pressure adsorption technology can operate effectively in the key positions of the mold for a long time.

[0013] 2. Negative pressure adsorption technology provides a new solution to the problem of material chipping in parts manufacturing. The improved Audi A6 rear cover inner panel reduces the number of parts stopping at the worktable by 50%.

[0014] 3. Reduce the mold maintenance cycle and the investment of mold maintenance personnel, extending the maintenance period from 1 production batch to 5 production batches. Attached Figure Description

Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0032] like Figures 1 to 3 As shown, this utility model provides a pneumatic material suction device for scrap, including a valve body 1, a valve core 2 and a valve core fixing bolt 3, all of which are hollow structures.

[0033] like Figure 1 As shown, the valve body 1 has a hollow stepped shaft structure, with a two-stage external step and a three-stage internal step, with the diameter increasing from left to right. The internal dimensions of the valve body 1 are adapted to the dimensions of the valve core 2, allowing the valve core 2 to be installed inside the valve body 1. The inner wall of the right end of the valve body 1 has an internal thread 11 for assembly with the valve core fixing bolt 3. The valve body 1 also has a main air inlet 12, which is located in the middle of the valve body 1 to allow airflow. In this preferred embodiment, the diameter of the main air inlet is 13.1 mm, and the air inlet pressure at this location is 6 bar (derived experimentally).

[0034] As shown in Figure 2, the valve core 2 is a hollow stepped shaft structure, divided into three parts: a left shaft 21, a middle shaft 22, and a right shaft 23. The outer diameters of the left shaft 21 and the right shaft 23 are equal and larger than the outer diameter of the middle shaft 22. The inner diameters of the left shaft 21 and the middle shaft 22 are equal. The right shaft 23 has a wedge-shaped channel 231 inside, with the diameter at the left end of the wedge-shaped channel 231 being larger than the diameter at the right end, forming a wedge shape. The valve core 2 has multiple valve core air passage holes 232, the center line of which is parallel to the inner wall of the wedge-shaped channel 231. In this preferred embodiment, the valve core air passage holes 232 are circular holes with a diameter of 2mm to 3mm, and there are six of them, evenly arranged on the left end of the right shaft 23. The six valve core air passage holes 232 connect the main air inlet 12 and the wedge-shaped channel 231.

[0035] like Figure 3 As shown, the left end of the valve core fixing bolt 3 is provided with an external thread 31, which is compatible with the internal thread 11 provided on the valve body 1. The left end of the valve core fixing bolt 3 is inserted into the right end of the valve body 1 and tightens the right end of the valve core 2.

[0036] The pneumatic material suction device for waste materials provided by this invention uses compressed gas with an inlet pressure of 6 bar, which is input through the main air inlet 12. This compressed gas enters the interior of the valve body 1, the periphery of the central shaft 22 of the valve core 2, and then enters the wedge-shaped channel 231 through the six valve core air passages 232. Finally, it is discharged through the valve core fixing bolt 3. In this process, the compressed air generates negative pressure to form an adsorption airflow that adsorbs the waste materials. The waste materials are discharged along with the compressed air, resulting in a significant waste material treatment effect.

[0037] It should be noted that the above description is only a preferred embodiment of this utility model and cannot limit the scope of implementation of this utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
