Description
Technical Field
[0001] This utility model belongs to the field of cemented carbide cutting tool technology, and specifically relates to a cleaning device for cemented carbide cutting tool processing. Background Technology
[0002] In today's booming modern manufacturing industry, cemented carbide inserts, with their high hardness, excellent wear resistance, good strength and toughness, and outstanding heat and corrosion resistance, are widely used in many key fields such as metal processing, construction, automotive manufacturing, and aerospace, becoming a leader among industrial cutting tools. Carbide inserts, with tungsten carbide as the main component and cobalt and other metals as binders, can maintain excellent cutting performance under harsh conditions of high speed and heavy load, significantly improving machining efficiency and product quality.
[0003] During the machining of carbide cutting tools, the tool surface is highly susceptible to various contaminants. Manufacturing processes such as powder pressing, high-temperature sintering, and tool grinding leave behind metal shavings, grinding fluid, oil, and other impurities on the tool surface. Furthermore, during subsequent storage and transportation, dust and moisture can adhere to the surface. These contaminants act like "time bombs," severely impacting the performance and quality of the cutting tools. They not only reduce cutting accuracy and surface quality, leading to defects in the machined products, but also accelerate wear and corrosion, shortening their lifespan and increasing production costs for the company.
[0004] Existing cleaning devices place the blades to be cleaned directly in the cleaning basket and then use a high-pressure nozzle installed on top to clean the dirt on the surface of the blades. This method can easily cause the blades to shift and stack when the cleaning basket rotates, creating cleaning dead corners between the stacked blades, which affects the cleaning quality and the lifespan of the alloy blades. Utility Model Content
[0005] The purpose of this invention is to provide a cleaning device for machining carbide cutting tools, which aims to solve the problem in the existing cleaning devices that, when cleaning carbide cutting tools, place the cutting tools to be cleaned directly flat in the cleaning basket and then use a high-pressure nozzle installed on the top to clean the stains on the surface of the carbide cutting tools. This method is prone to causing the cutting tools to shift and stack when the cleaning basket rotates, thus creating cleaning dead corners between the stacked carbide cutting tools during cleaning, which affects the cleaning quality and reduces the service life of the subsequent carbide cutting tools.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-5This utility model provides the following technical solution: a cleaning device for machining carbide blades, including a cleaning machine body 1, a cleaning net bag 2 provided on the inner wall of the cleaning machine body 1, a cleaning pipe 3 provided on the inner wall of the top cover of the cleaning machine body 1, a limiting groove 4 opened on the inner wall of the cleaning net bag 2, a protrusion 5 inserted into the surface of the limiting groove 4, a placement frame 6 connected to the surface of the protrusion 5, a limiting ring 7 sleeved on the transverse end surface of the inner wall of the placement frame 6, the surface of the limiting ring 7 threadedly connected to the surface of the placement frame 6 by a first bolt 8, a slot 9 opened on the surface of the limiting ring 7, a vertical rod of the surface of the first clamping plate 10 inserted into the surface of the slot 9, a second clamping plate 11 inserted into the open end surface of the first clamping plate 10, a vertical rod of the surface of the second clamping plate 11 inserted into the surface of the slot 9, and the surface of the placement frame 6... The surface of the limit frame 12 abuts against the limit frame 12. The connecting ear on the surface of the limit frame 12 is threadedly connected to the inner wall of the placement frame 6 by the second bolt 13. The inner wall surface of the placement frame 6 abuts against the third clamping plate 14. A horizontal bar 15 is connected to one side of the open end of the third clamping plate 14. The surface of the horizontal bar 15 is inserted into the circular groove 16 opened on the same side of the fourth clamping plate 17. The vertical bars on the surfaces of the third clamping plate 14 and the fourth clamping plate 17 are inserted into the through groove on the surface of the limit frame 12. In this design scheme, the washing machine body 1, the washing net bag 2 and the washing pipe 3 constitute the main body of the rotary washing machine. A large number of related components are set in the main body of the rotary washing machine. Since they are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.
[0024] The main model of the rotary cleaning machine in this solution is: 360° rotating high-pressure automatic spray cleaning machine.
[0025] In use: When the rotary cleaning machine body cleans the carbide blades, the blades are first fixed to the cleaning net bag 2 using the cooperation of the first clamping plate 10, the second clamping plate 11, the third clamping plate 14, and the fourth clamping plate 17, so that the blades rotate under the drive of the cleaning net bag 2. The cleaning machine body 1 starts the pre-spraying, using high-pressure clean water to initially rinse away large particles of impurities; then the spraying system sprays high-pressure, multi-angle special cleaning fluid, relying on the impact force to break the adhesion of the stains and peel them off; then, clean water is used to rinse away residual cleaning fluid and stains; finally, the blades are dried by hot air blowing or centrifugal drying to make them clean and dry, meeting the requirements of subsequent processes.
[0026] Preferably, the protrusion 5 is a "T" shaped rubber block, and the shape and size of the protrusion 5 are adapted to the limiting groove 4.
[0027] In practical use, the protrusion 5 is inserted into the limiting groove 4. At the same time, the protrusion 5 increases the friction at the intersection with the cleaning net bag 2, thereby fixing the position of the placement frame 6 inside the cleaning net bag 2. When the cleaning net bag 2 rotates, it drives the placement frame 6 to rotate together.
[0028] Preferably, the space frame 6, the limiting ring 7, and the first bolt 8 form a threaded connection structure.
[0029] In practical use, the position of the limiting ring 7 on the placement frame 6 is fixed by the connection between the placement frame 6 and the first bolt 8.
[0030] Preferably, the surface of the limiting ring 7 has slots 9 evenly distributed in an annular pattern, and the shape and size of the slots 9 are adapted to the rectangular blocks and vertical rods on both sides of the first clamping plate 10 and the second clamping plate 11.
[0031] In practical use, the slots 9 on the surface of the limiting ring 7 are used to insert the vertical rods on the surfaces of the first clamping plate 10 and the second clamping plate 11 respectively. Then, the limiting ring 7 is sleeved on the upper horizontal end surface of the placement frame 6, thereby using the connecting ears on the surface of the placement frame 6 and the threaded connection of the first bolt 8 to the position of the limiting ring 7 on the placement frame 6.
[0032] Preferably, rectangular through slots are respectively opened at the intersection of the first clamping plate 10 and the second clamping plate 11, and a transverse rubber rod is provided at the open end of the second clamping plate 11, and the shape and size of the transverse rubber rod are adapted to the groove at the open end of the first clamping plate 10.
[0033] In practical use, insert the bottom of the alloy blade that needs to be cleaned into the rectangular through slots opened at the opening ends of the first clamping plate 10 and the second clamping plate 11, and then press the first clamping plate 10 and the second clamping plate 11 that are inserted together toward the middle, thereby clamping and fixing the inserted alloy blade.
[0034] Preferably, five sets of rectangular through slots are equally spaced on the surface of the limiting frame 12, and the shape and size of the through slots are adapted to the rectangular structure on the surface of the third clamping plate 14 and the fourth clamping plate 17.
[0035] In practical use, the rectangular through groove on the surface of the limiting frame 12 is used to easily fit and fix the third clamping plate 14 and the fourth clamping plate 17. In this way, the position of the limiting frame 12 is used to fix the position of multiple sets of third clamping plates 14 and fourth clamping plates 17 on the placement frame 6, thereby fixing the position of the clamped alloy blade.
[0036] Preferably, the space frame 6, the limiting frame 12, and the second bolt 13 form a threaded connection structure.
[0037] In practical use, the threaded groove on the connecting ear of the limiting frame 12 and the second bolt 13 are used to thread the limiting frame 12 onto the inner wall of the placement frame 6, thereby fixing the position of the alloy blade held on it.
[0038] Working principle: During the machining of carbide cutting tools, the cleaning machine body 1 is used to rinse and clean the impurities adhering to the surface. Before cleaning, the appropriate first clamping plate 10, second clamping plate 11, third clamping plate 14, and fourth clamping plate 17 are selected according to the shape and size of the carbide cutting tool to be cleaned. Before cleaning, the first clamping plate 10 and the second clamping plate 11 are picked up, and the transverse rubber rod provided on the open end surface of the second clamping plate 11 is inserted into the groove opened on the surface of the first clamping plate 10. Then, the bottom position of the carbide cutting tool to be cleaned is inserted into the rectangular through slot opened at the open end of the first clamping plate 10 and the second clamping plate 11 in sequence. Then, the first clamping plate 10 and the second clamping plate 11 inserted together are pressed towards the middle, thereby cleaning the inserted cutting tool. The alloy blade is clamped and fixed. Following the above operation, multiple sets of first clamping plates 10 and second clamping plates 11 are repeatedly inserted and clamped to fix the alloy blade. Finally, the slots 9 on the surface of the limiting ring 7 are used to insert the vertical bars on the surfaces of the first clamping plates 10 and second clamping plates 11. The limiting ring 7 is then fitted onto the upper horizontal end surface of the placement frame 6. The connecting ears on the surface of the placement frame 6 and the first bolt 8 are used to thread the limiting ring 7 onto the placement frame 6, thus fixing the alloy blade to be cleaned onto the upper surface of the placement frame 6. Alternatively, the horizontal bar 15 and the circular groove 16 can be inserted together, and the alloy blade can be inserted into the groove between the horizontal bar 15 and the fourth clamping plate 17. The inserted horizontal bar 15 and the circular groove 16 are then pressed together. The third clamping plate 14 and the fourth clamping plate 17 are used together to clamp and fix the alloy blades. Finally, the rectangular groove on the surface of the limiting frame 12 is used to fit the third clamping plate 14 and the fourth clamping plate 17, thereby fixing the position of multiple sets of alloy blades clamped between the third clamping plate 14 and the fourth clamping plate 17. Then, the second bolt 13 connected to the surface of the limiting frame 12 is threaded to the inner wall surface of the bottom of the placement frame 6, thereby fixing the position of the alloy blades on the limiting frame 12. Then, the protrusions 5 provided on both sides of the surface of the placement frame 6 are inserted into the limiting grooves 4, thereby fixing the placement frame 6 to the inner wall of the cleaning net bag 2. At this time, the top cover on one side of the cleaning machine body 1 can be closed, and then the switch of the cleaning machine body 1 can be turned on. The installed cleaning pipe 3 sprays downwards to clean the alloy blades placed in the mesh frame 6. At the same time, the motor at the bottom of the cleaning net bag 2 drives it to rotate, so that the alloy blades on the cleaning net bag 2 can be adjusted at the angle and rinsed and cleaned by the cleaning pipe 3. During cleaning, the alloy blades, which are clamped and fixed in layers on the mesh frame 6, can be thoroughly cleaned by the cleaning pipe 3 at the top, avoiding the accumulation of dead corners and thus improving the cleaning efficiency and quality of the alloy blades. In addition, in this design, the mesh frame 6, the limiting ring 7, the first clamping plate 10, the second clamping plate 11, the limiting frame 12, the third clamping plate 14, and the fourth clamping plate 17 are all mesh structures, which facilitates the flow of cleaning water into the sewage collection chamber provided in the lower cleaning machine body 1.
[0039] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
