Description

Technical Field

[0001] The invention relates to the technical field of coating equipment, and in particular to a coating equipment and a process for depositing a coating on the surface of an alloy tool. Background Art

[0002] The coating equipment for depositing coating on the surface of the tool is specially used to form a layer of wear-resistant, corrosion-resistant or other special properties of thin film on the surface of the tool. This type of equipment mainly realizes the deposition of coating through methods such as physical vapor deposition (PVD) or chemical vapor deposition (CVD). Among them, PVD (physical vapor deposition) coating equipment is one of the commonly used equipment in tool coating. It uses physical forms such as evaporation or sputtering to remove materials from the target source, and deposits these energy-carrying vapor ions onto the tool substrate or part surface through a vacuum or semi-vacuum space to form the required film layer.

[0003] By coating a layer of material with special properties on the surface of a tool substrate such as cemented carbide or high-speed steel, the cutting performance and service life of the tool can be improved. After the tool is coated with a deposited coating on the surface, during the sandblasting process, the existing equipment cannot ensure that the surface of the tool substrate can be sandblasted because the tool mating surface placed on the frame remains unchanged, resulting in uneven sandblasting, which in turn leads to uneven surface processing quality of the tool substrate, greatly affecting the bonding stability between the coating and the tool substrate, making the existing tool coating easily peel off or break during the cutting process, resulting in poor stability of the tool coating during actual use.

DETAILED DESCRIPTION

[0028] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0029] See also Figures 1 to 10 The present invention provides a coating device for depositing coating on the surface of an alloy tool: it includes a coating box body 1, a sandblasting box body 2 and a working component, the working component includes a rotating frame 3, a matching base frame 4, a shelf component 5 and a matching component 6, the shelf component 5 includes a fixed plate 51, a connecting gear shaft 52, a tool placement cylinder 53 and an inner gear frame 54, the matching component 6 includes a telescopic bottom box 61, an insertion plate 62 and a telescopic driving top box 63. The above-mentioned scheme solves the problem that after the tool is coated with a surface deposited coating, the existing equipment part is uneven during sandblasting, resulting in a relatively concentrated sandblasting range, which in turn leads to uneven surface processing quality of the tool substrate, greatly affecting the bonding stability between the coating and the tool substrate, making the existing tool coating easily peel off or break during the cutting process, resulting in poor tool coating stability during actual use.

[0030] Furthermore, the coating box body 1 is mainly an existing equipment body for coating workpieces, and the coating box body 1 is mainly composed of a vacuum system, a heating system, a coating source, a gas control system, and a monitoring and control system.

[0031] The vacuum system mainly includes a vacuum chamber, a vacuum pump (such as a mechanical pump, a molecular pump, etc.), a vacuum gauge, and corresponding vacuum pipes and valves, so as to provide a low vacuum or high vacuum environment for the coating process to prevent air or other impurities from interfering with the coating process.

[0032] The heating system mainly includes heating elements (such as resistance wire, induction coil, etc.) and temperature controller, etc., so as to heat the substrate (i.e. tool) and coating material to achieve the required coating temperature. The coating source varies according to the coating technology.

[0033] The coating source can be an evaporation source (such as electron beam evaporation source, resistance evaporation source, etc.), a sputtering source (such as magnetron sputtering source, multi-arc ion plating source, etc.) or a chemical reaction source (such as a CVD reactor, etc.), which provides the material required for coating and deposits it onto the tool surface through a physical or chemical process.

[0034] The gas control system mainly includes a gas source (such as nitrogen, argon, etc.), a gas flow meter, a pressure gauge, and corresponding pipes and valves to control the type, flow and pressure of the gas in the coating chamber to ensure the stability and consistency of the coating process.

[0035] The monitoring and control system mainly includes various sensors (such as temperature sensors, pressure sensors, etc.), controllers (such as PLC controllers, computer control systems, etc.) and corresponding display and recording equipment, so as to monitor the various parameters in the coating process (such as temperature, pressure, gas flow, coating rate, etc.) in real time, and automatically adjust and control according to the preset process conditions.

[0036] The sandblasting box body 2 mainly sprays abrasives (such as quartz sand, steel shot, etc.) onto the surface of the tool substrate through high pressure to achieve the purpose of cleaning, deburring and roughening the surface. In this process, the high-speed impact of the abrasive can remove dirt, oxide layer, old coating, etc. on the surface of the tool, and at the same time form a certain roughness, which is conducive to the adhesion of the new coating.

[0037] Furthermore, the shelf component 5 is installed on the rotating frame 3 for placing the tool, and the rotating frame 3 is rotatably installed on the matching base frame 4, so that the placed tool can be driven to rotate accordingly and drive the placed tool to rotate by itself through the rotation of the rotating frame 3 and the matching base frame 4 is rotatably arranged on the matching base frame 4 through the connecting rod provided below, so that the matching base frame 4 and the rotating frame 3 can rotate normally, and at the same time, the top of the rotating frame 3 and the bottom of the matching base frame 4 are also provided with matching platforms for cooperating with subsequent mechanisms, and the two matching platforms are mainly distributed at corresponding positions of the matching base frame 4 and the rotating frame 3 through the hexagonal rods provided, and at the same time, the surfaces of the two matching platforms are also provided with hexagonal sockets, so as to cooperate with the subsequent mechanism to complete the mutual rotation drive between the matching base frame 4 and the rotating frame 3.

[0038] Furthermore, the fixed disk 51 is fixedly mounted on the rotating frame 3; the connecting gear shaft 52 is rotatably set on the fixed disk 51; the tool placement tube 53 is fixedly mounted on the connecting gear shaft 52; the inner gear frame 54 is meshed with the connecting gear shaft 52 and fixedly mounted on one side of the matching base frame 4, and the fixed disk 51 is fixedly sleeved on the connecting rod provided under the rotating frame 3, and a plurality of connecting gear shafts 52 are rotatably mounted on the fixed disk 51, and each of the connecting gear shafts 52 is fixedly mounted with the tool placement tube 53, and the tool placement tube 53 is a tooling element for installing and placing the tool to be processed, and each connecting gear shaft 52 is fixedly mounted with the tool placement tube 53. The gears on the shaft 52 are all meshed with the internal teeth of the internal gear frame 54 fixedly mounted on the matching base frame 4. When the rotating frame 3 rotates on the matching base frame 4, the fixed disk 51 provided on the rotating frame 3 will drive the multiple groups of connecting gear shafts 52 and the tool placement tube 53 to rotate. At this time, due to the cooperation between the connecting gear shafts 52 and the internal gear frame 54, when the fixed disk 51 rotates, the connecting gear shaft 52 will drive the tool placement tube 53 to rotate, so that the tool placed on the tool placement tube 53 can complete uniform surface processing through the rotation of the fixed disk 51 and its own rotation.

[0039] Preferably, the matching component 6 includes a telescopic bottom box 61, an insert plate 62 and a telescopic drive top box 63. The telescopic bottom box 61 is installed on the inner bottom wall of the coating box body 1 and the sandblasting box body 2, and the telescopic drive top box 63 is installed on the inner top wall of the coating box body 1 and the sandblasting box body 2. The insertion block is installed on the telescopic bottom box 61 and the telescopic drive top box 63. The corresponding insert plate 62 is driven by the telescopic bottom box 61 to cooperate with the top matching platform of the rotating frame 3, and then the insert plate 62 arranged on the telescopic drive top box 63 cooperates with the bottom matching platform of the matching base frame 4, thereby completing the corresponding station installation of the rotating frame 3 and the matching base frame 4. The telescopic bottom box 61 is mainly composed of an external installation box and a telescopic cylinder that can be telescoped, and the insert plate 62 is fixedly installed on the telescopic bottom box 61. On the output end of the telescopic cylinder provided, the structure of the telescopic driving top box 63 is similar to that of the telescopic bottom box 61, and is also composed of a box body and an internal driving member. The driving member inside the telescopic driving top box 63 is composed of a cylinder for telescoping and a motor for rotating and driving the insert plate 62. A mounting frame is fixed on the output end of the telescopic cylinder provided in the telescopic driving top box 63, and a corresponding motor is installed in the mounting frame. The insert plate 62 arranged on the telescopic driving top box 63 is fixed to the output shaft of the motor, and a corresponding hexagonal column boss is provided at the end of the insert plate 62 to facilitate cooperation with the hexagonal holes on the surface of the cooperating table of the rotating frame 3 and the cooperating base frame 4. It should be noted that in normal operation, the cooperating base frame 4 remains stationary due to the cooperation with the telescopic bottom box 61, and only the rotating frame 3 will rotate under the drive of the telescopic driving top box 63.

[0040] When the present embodiment is in use, the coating box body 1 and the sandblasting box body 2 can cooperate with the insert plate 62 on the telescopic driving top box 63 through the top matching boss of the rotating frame 3, and then cooperate with the insert plate 62 on the telescopic bottom box 61 through the bottom matching platform of the matching bottom frame 4 to complete the corresponding installation of the rotating frame 3 and the matching bottom frame 4. Since the insert plate 62 on the telescopic bottom box 61 can only be raised and lowered, and the insert plate 62 on the telescopic driving top box 63 can be rotated, the rotating frame 3 can be driven to rotate by the insert plate 62 on the telescopic driving top box 63. When the rotating frame 3 is rotated, When rotating, the fixed disk 51 will drive the multiple groups of connecting gear shafts 52 and the tool placement tube 53 to rotate, and the connecting gear shaft 52 can drive the tool placement tube 53 to rotate by itself when rotating driven by the fixed disk 51 through cooperation with the internal gear frame 54, so that the internal working components of the coating box body 1 and the sandblasting box body 2 can cooperate more evenly on the tool surface when working, and it is achieved that the tool substrate placed during sandblasting and subsequent coating processes can be evenly processed through the provided components, so that the combination between the coating and the tool substrate is more stable, avoiding the coating from peeling off or breaking during the cutting process.

[0041] Preferably, the absorption mechanism 9 includes a vacuum cleaner 91 , a flushing rack 92 and a purge component 93 , and the purge component 93 includes a purge bracket 931 , a connecting pipe 932 , an air pump 933 , an electric heating plate 934 and a storage box 935 .

[0042] Specifically, the connecting passage 7 connects the coating box body 1 and the sandblasting box body 2; the coating box body 1 and the sandblasting box body 2 are both provided with the lifting sealing door 8; the absorption mechanism 9 is arranged on the connecting passage 7 to complete the cleaning and absorption of surface impurities during and after tool processing; the transfer mechanism 10 is installed on the connecting passage 7 to complete the connection of the corresponding working procedures of the processed workpiece, and the vacuum cleaner 91 is installed on one side of the sandblasting box body 2; the flushing rack 92 is installed in the sandblasting box body 2; the blowing component 93 is arranged on the connecting passage 7, and is used for blowing, preheating and secondary cleaning of the workpieces in the transfer process, and the coating box body 1 and the sandblasting box body 2 are both provided with two openings, the front opening is provided with a corresponding working door leaf, and the rear opening is connected through the connecting passage 7. A corresponding lifting and sealing door 8 is also provided at the rear opening of the sand box body 2. The lifting and sealing door 8 is mainly composed of a door panel and a driving member that drives the door panel to move up and down. The coating box body 1 and the sandblasting box body 2 are mainly separated by the up and down movement of the corresponding door panel to avoid mutual interference between the two working boxes when working. The sandblasting box body 2 is provided with the corresponding vacuum cleaner 91 and flushing rack 92. The dust suction port of the vacuum cleaner 91 is arranged on the inner side of the sandblasting box body 2 to absorb the grit and dust generated after sandblasting, and the flushing rack 92 is used to flush and clean the tool after processing to avoid grit and dust adhering to the surface of the tool. It is worth noting that when the tool is sandblasted and flushed, the entire rotating frame 3 and the matching base frame 4 are in a working rotating state, so that the tool can be cleaned more thoroughly.

[0043] Furthermore, the purge bracket 931 is arranged on one side of the connecting channel 7; the air pump 933 is connected to the purge bracket 931 through the connecting pipe 932, and the electric heating plate 934 is arranged in the connecting pipe 932; the storage box 935 is connected to the air pump 933 and is arranged on one side of the connecting channel 7, the purge bracket 931 is connected with the air outlet end of the air pump 933 through the connecting pipe 932, and the storage box 935 is connected with the air inlet end of the air pump 933 through the corresponding channel, and the electric heating plate 934 is arranged in the connecting pipe 932. When the workpiece is transported in the connecting channel 7 through the transport mechanism 10 provided, the air pump 933 can introduce the airflow heated by the electric heating plate 934 into the purge bracket 931 through the connecting pipe 932, and then the purge bracket 931 blows the airflow to the transfer mechanism 10. The workpieces in the process of transportation are dried quickly after being rinsed by the rinsing rack 92 with the cooperation of the hot air flow. At the same time, since the blowing and cleaning bracket 931 is arranged on the side close to the coating box body 1, when the workpiece is continuously approaching the coating box body 1 under the drive of the transfer mechanism 10, the workpiece will begin to be preheated due to the cooperation with the hot air, so as to facilitate the subsequent entry into the coating box body 1 for rapid and stable coating. Moreover, since the air inlet end of the air pump 933 is connected with the storage box 935, the air flow will pass through the storage box 935 and then enter the air pump 933 to complete the circulation. The storage box 935 is provided with an inclined dust filter plate, which is convenient for blocking and collecting impurities such as dust blown off, so as to avoid the dust impurities that have not been thoroughly cleaned in the sandblasting box body 2 from leaking into the connecting channel 7 and then affecting the subsequent cooperation between the workpiece and the coating box body 1.

[0044] When the present embodiment is in use, the dust and impurities generated by the internal working of the sandblasting box body 2 can be cleaned by the vacuum cleaner 91 in cooperation with the flushing rack 92, and the cutting tools can be flushed and cleaned at the same time. When the cutting tools are flushed, the rotation of the rotating rack 3 and the corresponding rotation of the cutting tool placement tube 53 on the fixed plate 51 can greatly ensure the final cleaning quality of the cutting tools. Then, the frame for placing the cutting tools composed of the rotating rack 3 and the matching base frame 4 is driven by the transfer mechanism 10 into the connecting channel 7, and then cooperates with the coating box body 1. When the entire frame structure for placing the cutting tools is transferred in the connecting channel 7, the air pump 933 will pass the airflow heated by the electric heating plate 934 through the blowing support The workpiece is guided out from the rack 931, and then returns to the air inlet end of the air pump 933 after passing through the storage box 935. Through the cooperation of the heated airflow and the surface of the tool, not only can the tool to be processed be quickly dried, but the tool can also be preheated to a certain extent. The connection between the two processes of the coating box body 1 and the sandblasting box body 2 can be completely sealed through the corresponding mechanism of the connecting channel 7, that is, the workpiece will not contact the external environment when the two processes are switched, so that the tool will not be attached to the surface due to contact with the external environment after the sandblasting pretreatment is completed, thereby better ensuring the stability of the cooperation between the coating and the substrate when the surface of the tool substrate is coated in the coating box body 1, greatly enhancing the practicality of the entire device.

[0045] Preferably, the transfer mechanism 10 provided by the present invention includes a transfer base 101 and a clamping component 102 , and the clamping component 102 includes a mounting main frame 1021 , an insert rod 1022 and a driving element 1023 .

[0046] Specifically, the transfer base 101 is installed in the connecting channel 7; the clamping component 102 is installed on the transfer base 101, so that the clamping component 102 is driven in the corresponding direction by the transfer base 101, and the installation main frame 1021 is set on the transfer base 101; the insertion rod 1022 is installed on the installation main frame 1021, and the driving element 1023 is used to drive the insertion rod 1022 to clamp, and the transfer base 101 is composed of two plates that can move relative to each other, and the bottom plate of the rotating base is slidably arranged on the The bottom plate of the rotating base can be freely moved in the connecting channel 7 by a screw driving mechanism, and the mounting plate slidably mounted above the bottom plate of the rotating base is also driven by a screw driving mechanism. The mounting main frame 1021 is fixedly arranged on the mounting plate, and the mounting main frame 1021 is slidably mounted with two insertion rods 1022, and the insertion rods 1022 are sideways "U"-shaped clamping frames, and the upper and lower withdrawal platforms of the two insertion rods 1022 cooperate with the rotating frame 3 and the matching platform of the matching base frame 4 to simultaneously complete the alignment. The two plug rods 1022 are provided with corresponding matching holes at the positions for matching with the matching platform, so as to match with the hexagonal rods provided on the matching platform. After the upper and lower platforms of the two plug rods 1022 are combined, the hexagonal rods of the matching platform of the rotating frame 3 and the matching base frame 4 can be clamped, so that the entire frame composed of the rotating frame 3 and the matching base frame 4 can be driven to move and transfer. The driving element 1023 is mainly used to drive the two plug rods 1022. The driving element 1023 is composed of two double-headed screws and a driving element 1023. The structure is composed of two double-headed screws that rotate synchronously. The thread directions of the threads on both sides of the double-headed screw are opposite to each other, so that when the insertion rods 1022 on both sides are driven, the insertion rods 1022 on both sides can be brought together or spread out at the same time, thereby completing the corresponding clamping and loosening. At the same time, corresponding gears are also provided on the side ends of the two double-headed screws, and the two gears are connected by a tooth chain. One of the double-headed screws is driven by a set motor, so that when one double-headed screw rotates, the other double-headed screw can rotate together through the tooth chain and the gear to complete the stable and synchronous driving of the two insertion rods 1022.

[0047] When the present embodiment is in use, the transfer base 101 can drive the entire clamping component 102 to move in the corresponding direction, and then the driving element 1023 can drive the insertion rod 1022 on the mounting main frame 1021 to clamp and cooperate with the entire processing tool placement frame composed of the rotating frame 3 and the matching base frame 4, thereby completing the automatic connection of the two processes of the processing workpiece, so as to cooperate with the provided connecting channel 7 to achieve complete sealing during the connection of the two processes, which not only enhances the efficiency of the connection between the sandblasting pretreatment and the coating processing, but also can achieve isolation from the external environment during the connection process, avoid the surface quality of the processed workpiece being unstable due to manual transfer and contact with the external environment, so that the tool substrate can be more stably combined with the coating during the coating process, greatly enhancing the practicality of the entire device.
