Description

Technical Field

[0001] This invention belongs to the field of milling cutter technology, specifically an assembled milling cutter and its processing device. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, the cutting teeth sequentially and intermittently remove the excess material from the workpiece. It is mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces. Today, it has developed into a complete industrial system and is widely used in many scenarios. Assembled milling cutters are a type of milling cutter that adopts an assembled structure. Assembled milling cutters require a machining device during processing. The machining device typically includes processes such as blank preparation, roughing, heat treatment, precision machining, sharpening, coating treatment, and precision inspection.

[0003] In existing assembly-type milling cutters, during coating treatment, a large batch of milling cutters to be coated is usually placed in a reaction chamber, and gas is then transported into the reaction chamber through a pipeline for mixing and reaction. However, due to the single-channel air intake and the fact that the reaction gas enters from the top and exits from the bottom of the reaction chamber, the gas is simply mixed in the reaction chamber, resulting in unstable gas mixing ratios, affecting the uniformity of coating composition, and uneven diffusion of reaction gas. This leads to incomplete coating coverage of deep cavity parts in the reaction chamber, reducing the coating treatment efficiency of the milling cutters, lowering the yield of milling cutter machining, and failing to meet people's needs.

Several oblique air outlets 41 are arranged in a circular array. Several circular air outlets 42 are arranged in a circular array on the air outlet inner pipe 40. The number of circular air outlets 42 is less than the number of oblique air outlets 41. The first air outlet outer pipe 39 and the air outlet inner pipe 40 are used in conjunction with the air inlet structure 6, so that the air inlet from all sides can avoid the problem of excessively strong central airflow and weak edge airflow in traditional top air inlet. The gas diffuses along the side wall of the reaction chamber 4 and converges towards the center for discharge, which can reduce the dead angle of airflow and make the gas concentration distribution on the surface of the blade 1 more uniform.

[0057] In this embodiment, when the first outer outlet pipe 39 and the inner outlet pipe 40 are subjected to negative pressure suction, the oblique outlet 41 draws the gas into the first outer outlet pipe 39, and the circular outlet 42 draws the gas into the inner outlet pipe 40, forming a directional and uniform negative pressure airflow, while increasing and enhancing the central negative pressure gradient and improving the gas discharge effect.

[0058] In this invention, the bottom end of the first exhaust pipe 39 extends into the interior of the support platform 28 and is connected to the second exhaust pipe 44 via a connecting pipe head 43. The second exhaust pipe 44 is L-shaped, with one end of the second exhaust pipe 44 sealingly extending out of the reaction chamber 4. One end of the exhaust pipe 40 extends out of the reaction chamber 4 along the interior of the first exhaust pipe 39 and the second exhaust pipe 44. A vacuum pump 45 and an external connector 46 connected to the vacuum pump 45 are provided on the outside of the reaction chamber 4. One end of the second exhaust pipe 44 is connected to the external connector 46 and communicates with the vacuum pump 45 through an auxiliary channel of the external connector 46. One end of the exhaust pipe 40... One end is connected to the external connector 46 and is connected to the vacuum pump 45 through the main channel of the external connector 46. The diameter of the inner outlet pipe 40 is smaller than that of the first outer outlet pipe 39. When used with the external connector 46, the negative pressure suction intensity of the inner outlet pipe 40 is higher than that of the first outer outlet pipe 39. The other end of the vacuum pump 45 is connected to the processing equipment 47, so that the processing equipment 47 can process and purify the collected reaction gas. The reaction chamber 4 is equipped with a differential pressure sensor connected to the vacuum pump 45. Thus, through the staged vacuum design of the outlet structure 7, the film thickness deviation caused by airflow turbulence is avoided.

[0059] In this embodiment, the air pump 45 is started, and the first air outlet pipe 39 and the second air outlet pipe 44 are used in conjunction with the external connector 46 to perform negative pressure air intake, and the air outlet inner pipe 40 is also used to perform negative pressure air intake, so as to achieve stable air intake, and the intake air is introduced into the treatment device 47 for purification treatment.

[0060] In this invention, the inner outlet pipe 40 is provided with a cooling pipe 48. Both ends of the cooling pipe 48 are sealed and extend out of the inner outlet pipe 40 near the external connector 46, and are connected to a water supply end and a drain end. This allows the inner outlet pipe 40 to cool the first outer outlet pipe 39 in real time through the cooling water in the cooling pipe 48, thereby controlling the surface temperature of the first outer outlet pipe 39, avoiding premature decomposition of the reaction gas due to high temperature, and reducing film impurity defects.

[0061] In this embodiment, cooling water is provided to the cooling pipe 48 and the cooling water flows in the cooling pipe 48 to cool the first gas outlet outer pipe 39 and the gas outlet inner pipe 40, thereby avoiding premature decomposition of the reaction gas due to high temperature and reducing film impurity defects.

[0062] Example 3 Based on Example 2, referring to Figure 2 and9 - Figure 10 This is the third embodiment of the present invention. In this invention, a collection box 49 is fixedly provided on the upper end of the rotating plate 29. A filter cover 50 is vertically provided on the collection box 49. The filter cover 50 is located outside the first gas outlet pipe 39 and filters the reaction gas entering the first gas outlet pipe 39 and the gas outlet inner pipe 40. A connection hole matching the first gas outlet pipe 39 is provided at the bottom end of the filter cover 50.

[0063] In this embodiment, when the first external exhaust pipe 39 and the internal exhaust pipe 40 are subjected to negative pressure intake, the filter cover 50 filters the intake gas to prevent the oblique exhaust port 41 and the circular exhaust port 42 from being blocked, thereby reducing the number of maintenance operations required for the oblique exhaust port 41 and the circular exhaust port 42.

[0064] In this invention, the bottom end of the air guide 58 is vertically provided with a telescopic rod 51, the bottom end of the telescopic rod 51 is provided with a mounting plate 52, and the bottom end of the mounting plate 52 is vertically provided with a scraper 53 for cleaning the filter cover 50. The bottom end of the scraper 53 extends into the collection box 49. The upper end of the collection box 49 is provided with a rotating groove for the scraper 53 to rotate, and the bottom end of the collection box 49 is provided with an annular discharge groove 54 for cleaning impurities from the scraper 53 and discharging them. The support platform 28 is provided with a ring that is sealed and connected to the annular discharge groove 54. The annular guide 55 has a funnel-shaped feeding trough evenly provided on its inner side. The bottom end of the annular guide 55 is provided with a feeding pipe 56 that is aligned and connected to the feeding trough. One end of the feeding pipe 56 is detachably connected to the lower part of the first air outlet pipe 39. The support platform 28 and the rotating plate 29 are both provided with connecting grooves that match the annular guide 55. The end of the second air outlet pipe 44 near the external connector 46 is provided with a filter box 59 for filtering impurities. The filter box 59 adopts an automatic cleaning design.

[0065] In this embodiment, the telescopic rod 51 is adjusted so that the mounting plate 52 drives the scraper 53 to move and make the scraper 53 fit against the outer wall of the filter cover 50. When the rotating plate 29 rotates, it drives the collection box 49 to rotate, which in turn drives the filter cover 50 to rotate, allowing the scraper 53 to clean the filter cover 50. The vacuum pump 45 is started so that the second exhaust pipe 44 and the first exhaust pipe 39 perform negative pressure suction, which causes the feed pipe 56 to perform negative pressure suction on the annular guide 55. The annular guide 55 performs negative pressure suction on the collection box 49 through the annular discharge groove 54, so that the scraper 53 guides the cleaned impurities into the collection box 49 and guides the impurities into the filter box 59 through the annular discharge groove 54, the annular guide 55, the feed pipe 56, the first exhaust pipe 39 and the second exhaust pipe 44 for filtration.
