Description

Technical Field

[0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a shearing machine for manufacturing mechanical parts and a use method thereof. Background Art

[0002] A shearing machine is a machine that uses a blade to shear plates by reciprocating linear motion. The plates sheared are generally thin metal plates.

[0003] However, when the existing shearing machine is in use, metal debris will stick to the blade after one shearing. The long-term accumulation of metal debris is not conducive to shearing the plate and is not conducive to quickly cleaning the metal debris on the blade. In response to the above technical problems, the applicant has retrieved some prior arts, such as the Chinese patent with patent announcement number CN113560660A, which is equipped with an automatic chip wiping device on the support table when in use. The metal debris on the cutting blade edge is wiped off by the automatic chip wiping device, reducing the wear of the cutting blade by the metal debris. However, when the shearing machine is in use, the blade is used frequently, and the friction between the blade and the plate will increase the wear and generate a lot of heat. In order to maintain the stability and reliability of the equipment operation, lubricating oil will be applied to the blade. Since the lubricating oil has a certain viscosity and its chip wiping device pushes the impurities upward along the side of the blade, a small amount of impurities will be adsorbed on the blade under the action of the viscosity of the lubricating oil, making it difficult to completely remove the impurities on the blade, affecting the shearing quality of the plate. Summary of the invention

[0006] Further technical solution: two groups of brackets located on both sides of the shearing groove are fixedly installed on the base, and the horizontal sections of the two groups of brackets are slidably installed with a top plate together. A second telescopic member pointing to the base is fixedly installed on the top plate, and the second telescopic member drives the shearing knife to move up and down. One group of the horizontal sections of the brackets is fixedly installed with a first telescopic member, and the output end of the first telescopic member is fixedly connected to the top plate.

[0007] Further technical solution: A connecting frame with a frame-type structure is fixedly installed on the top of the cleaning box, and two symmetrical inner walls of the connecting frame are connected to multiple groups of linearly spaced blowing pipes. The cleaning box is fixedly connected to the top plate through a connecting rod, and the connecting frame is connected to the fan fixedly installed on the base through a first air duct.

[0008] Further technical solution: A baffle plate with an angle to the horizontal plane is fixedly installed at the bottom of the cleaning box. The baffle plate and the inner wall of the cleaning box form a cleaning cavity. Multiple groups of air holes are provided on the baffle plate. The cleaning cavity is connected to the fan through a second air duct. A valve is provided on the second air duct. Both the first air duct and the second air duct are hoses.

[0009] Further technical solution: A circulating pump is fixedly installed on the installation box, and the circulating pump is connected to a liquid extraction pipe. The liquid extraction pipe extends into the installation box and a collecting hose is connected to the end of the liquid extraction pipe. The collecting hose is connected to the cleaning box. Through grooves located between the first scraper and the second scraper are provided on both side walls of the cleaning box, and the liquid outlet end of the circulating pump is connected to the installation box.

[0010] Further technical solution: a filter cartridge is fixedly installed in the liquid extraction tube, a rotating shaft is rotatably installed at the end of the filter cartridge, a fan blade is fixedly installed on the rotating shaft, a cleaning plate is fixedly installed on the rotating shaft, and the cleaning plate is in sliding contact with the surface of the filter cartridge.

[0011] Further technical solution: the liquid extraction pipe is connected with a drop pipe, the drop pipe penetrates the side wall of the installation box and a collecting cylinder surrounding the drop pipe is arranged on the installation box, and impurities dropped from the filter cartridge enter the collecting cylinder through the drop pipe.

[0012] Further technical solution: a support plate located inside the collecting tube is fixedly installed on the installation box, a threaded rod is threadedly installed on the support plate, a closing plate for closing the end of the drop tube is fixedly installed on the end of the threaded rod, a rotating tube is rotatably installed on the collecting tube, the rotating tube and the threaded rod are coaxially arranged, the threaded rod extends into the rotating tube and the two are in sliding contact, and the cross-section of the part of the threaded rod extending into the rotating tube is a non-circular structure.

[0013] The present invention also provides a method for using a shearing machine for manufacturing mechanical parts, which is applied to the above-mentioned shearing machine for manufacturing mechanical parts, and comprises the following steps: Step S1: Add a sufficient amount of lubricating liquid into the installation box, place the plate on the base and adjust it to the cutting position, and press and fix the plate by the fixing module; Step S2: according to the need of cutting the plate, the top plate is driven to move by the first telescopic member, so as to adjust the position of the shearing knife, and then the second telescopic member drives the shearing knife to move downward to shear the plate; Step S3: After cutting, the shearing knife continues to move downward into the cleaning box, and performs preliminary cleaning through the bubbles generated by the air in the cleaning chamber. At the same time, the circulating pump drives the lubricating liquid in the cleaning box to flow, and the shearing knife is continuously rinsed by the flow of the lubricating liquid. Then, the shearing knife moves upward to scrape off the impurities and lubricating liquid on the side of the shearing knife through the first scraper and the second scraper, and the cleaning is completed; Step S4: When the circulation pump extracts the lubricating fluid for circulation, the impurities in the lubricating fluid are filtered through the filter cartridge and collected through the collecting cartridge. The impurities in the collecting cartridge can be subsequently cleaned.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the shearing knife moves to the lowest position, the second scraper and the first scraper will rotate upward under the action of magnetic force until the movable ends of the first scraper and the second scraper are in contact with the side of the shearing knife, and then the shearing knife moves upward to rub against the first scraper and the second scraper, and the impurities on the side of the shearing knife are scraped from top to bottom by the first scraper, ensuring that the impurities on the side of the shearing knife can be completely scraped off, thereby improving the cleaning effect of the impurities on the shearing knife, and then improving the shearing quality of the subsequent shearing knife. Since the cleaning box is full of lubricating liquid, the shearing knife is soaked in the lubricating liquid during the downward movement. Due to the increase of lubricating liquid, the adhesion between the impurities and the shearing knife is reduced, so that the first scraper can easily scrape the impurities off the shearing knife, further improving the cleaning effect of the shearing knife.

[0015] 2. When the shearing knife moves downward into the cleaning groove, air is transported into the cleaning chamber. The air flows upward through the air holes in the lubricating fluid, and a large number of bubbles are formed in the lubricating fluid. A large number of bubbles flow upward and contact the shearing knife and impact the impurities attached to the side of the shearing knife. Under the action of the impact, the impurities on the surface of the shearing knife are mobilized, making it easier for the impurities to detach from the shearing knife, thereby further improving the cleaning effect of the impurities on the shearing knife.

[0016] 3. The circulation pump extracts the lubricating liquid in the cleaning box through the suction pipe and the collecting hose and then transports the lubricating liquid to the installation box again, so that the lubricating liquid in the installation box circulates, and the lubricating liquid enters the cleaning box from the through groove and flows downward and flows out from the bottom of the cleaning box. When the shearing knife is located in the cleaning box, the lubricating liquid flowing downward produces friction contact with the side of the shearing knife, and then the impurities on the side of the shearing knife are further cleaned by the flow of the lubricating liquid. At the same time, the fallen impurities will be directly discharged from the cleaning box with the lubricating liquid, so as to avoid the fallen impurities from adhering to the shearing knife again, thereby further improving the cleaning effect of the shearing knife.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0027] like Figure 1-Figure 4As shown, a shearing machine for manufacturing mechanical parts provided by the present invention comprises a base 1, a mounting box 11 is fixedly installed on the bottom surface of the base 1, a shearing groove 2 connected with the mounting box 11 is opened on the base 1, a shearing knife 7 is arranged on the base 1, and the shearing knife 7 enters the mounting box 11 through the shearing groove 2 when moving downward, two groups of brackets 3 located on both sides of the shearing groove 2 are fixedly installed on the base 1, and a top plate 4 is slidably installed on the horizontal sections of the two groups of brackets 3 together, and a second telescopic member 6 pointing to the base 1 is fixedly installed on the top plate 4, and the second telescopic member 6 drives the shearing knife 7 to move up and down, and a first telescopic member 5 is fixedly installed on the horizontal section of one group of brackets 3, and the output end of the first telescopic member 5 is fixedly connected to the top plate 4; A cleaning box 12 with its opening facing the base 1 is slidably installed in the installation box 11, and a first scraper 14 and a second scraper 15 are rotatably installed on both symmetrical side walls of the cleaning box 12, and the first scraper 14 and the second scraper 15 on the same side are connected by a pull wire 24. Electromagnets 17 are fixedly installed on both symmetrical side walls of the cleaning box 12. When the electromagnet 17 is energized, it adsorbs the iron plate 16 fixedly installed on the second scraper 15, and when the first scraper 14 and the second scraper 15 rotate to the upper end of the stroke, their ends contact the side of the shearing knife 7.

[0028] In actual application of this embodiment, first add a sufficient amount of lubricating liquid into the installation box 11 so that the cleaning box 12 is also filled with lubricating liquid, place the sheared plate on the base 1, push the plate to cross the shearing groove 2 and move to the set position, then fix the plate through the fixing module 8, and then the second telescopic member 6 drives the shearing knife 7 to move downward and cooperate with the shearing groove 2 to complete the shearing of the plate, and then the shearing knife 7 continues to move downward into the cleaning box 12, when the shearing knife 7 moves to the lowest position, the electromagnet 17 is energized and absorbs the iron plate 16 on the second scraper 15, at this time, the second scraper 15 and the first scraper 14 will rotate upward under the action of magnetic force, and stop rotating when the iron plate 16 contacts the electromagnet 17, at this time, the first scraper 14 and the second scraper 15 The movable ends are in contact with the side surfaces of the shearing blade 7, and the contact position of the second scraper 15 and the shearing blade 7 is located above the liquid surface of the lubricating liquid. Then, the shearing blade 7 moves upward to rub against the first scraper 14 and the second scraper 15, and the impurities on the side surfaces of the shearing blade 7 are scraped from top to bottom by the first scraper 14, ensuring that all the impurities on the side surfaces of the shearing blade 7 can be scraped off, thereby improving the cleaning effect of the impurities on the shearing blade 7, and further improving the shearing quality of the subsequent shearing blade 7. Since the cleaning box 12 is full of lubricating liquid, the shearing blade 7 is soaked in the lubricating liquid during the downward movement. Due to the increase of the lubricating liquid, the adhesion between the impurities and the shearing blade 7 is reduced, so that the first scraper 14 can easily scrape the impurities off the shearing blade 7, further improving the cleaning effect of the shearing blade 7. Afterwards, the lubricating liquid remaining on the side of the shearing blade 7 is scraped off by the second scraper 15 to avoid more lubricating liquid remaining on the shearing blade 7, thereby reducing the adsorption force of the lubricating liquid on impurities during shearing by the shearing blade 7, reducing the probability of impurities being adsorbed on the shearing blade 7, which is beneficial to improving the shearing quality of the shearing blade 7, and at the same time, it can also further clean the impurities again to avoid impurity residue. When the lower end of the shearing blade 7 leaves the second scraper 15, the electromagnet 17 is powered off, and the first scraper 14 and the second scraper 15 rotate downward under the action of gravity and contact the pad. The pad prevents the iron plate 16 from being away from the electromagnet 17, ensuring that the first scraper 14 and the second scraper 15 can stably rotate upward; According to the use requirements, the top plate 4 is driven to move by the first telescopic member 5, and then the gap between the shearing knife 7 and the edge of the shearing groove 2 is adjusted, so that different materials can be sheared.

[0029] In an example of the present embodiment, the first telescopic member 5 and the second telescopic member 6 are respectively the first electric telescopic rod and the second electric telescopic rod. Of course, they can also be other components that can actively change the length, such as a hydraulic cylinder. The first electric telescopic rod drives the shearing knife 7 to move horizontally, and the second electric telescopic rod drives the shearing knife 7 to move in the vertical direction. The fixing module 8 can be an electric telescopic rod that drives the pressure plate to be clamped and fixed, or it can be a servo module that drives the pressure plate to move and clamp and fix.

[0030] like Figure 3-Figure 5 As shown, a shearing machine for manufacturing mechanical parts provided by the present invention is provided. A connecting frame 13 of a frame structure is fixedly installed on the top of the cleaning box 12. The two symmetrical inner walls of the connecting frame 13 are connected with multiple groups of linearly spaced blowing pipes 22. The cleaning box 12 is fixedly connected to the top plate 4 through a connecting rod 9, and the connecting frame 13 is connected to the fan 23 fixedly installed on the base 1 through a first air duct 25.

[0031] Specifically, a baffle 19 is fixedly installed at the bottom of the cleaning box 12 and is set at an angle to the horizontal plane. The baffle 19 and the inner wall of the cleaning box 12 form a cleaning chamber 20. A plurality of air holes 21 are provided on the baffle 19. The cleaning chamber 20 is connected to the fan 23 through a second air duct 26. A valve is provided on the second air duct 26. The first air duct 25 and the second air duct 26 are both hoses.

[0032] In actual application of this embodiment, when the top plate 4 moves horizontally, it drives the cleaning box 12 and the connecting frame 13 to move with it, ensuring that the positions of the cleaning box 12 and the connecting frame 13 always correspond to the shearing knife 7. The fan 23 delivers air to the connecting frame 13 and the cleaning chamber 20 through the first air duct 25 and the second air duct 26 respectively. The air in the connecting frame 13 is continuously delivered. Whether the air is delivered in the cleaning chamber 20 is controlled by the valve on the second air duct 26. In normal use, the cleaning box 12 and the installation box 11 are filled with lubricating liquid. When the shearing knife 7 enters the cleaning box 12 downward, the air is delivered to the cleaning chamber 20. Air, the air flows upward through the air hole 21 in the lubricating liquid, and a large number of bubbles are formed in the lubricating liquid. A large number of bubbles flow upward and contact the shearing blade 7 and impact the impurities attached to the side of the shearing blade 7. Under the action of the impact, the impurities on the surface of the shearing blade 7 are moved, making it easier for the impurities to separate from the shearing blade 7, further improving the cleaning effect of the impurities on the shearing blade 7. When the shearing blade 7 moves upward, the valve on the second air duct 26 is closed, and no more bubbles are generated in the cleaning box 12 at this time, so as to prevent the bubbles from carrying impurities upward and attaching to the shearing blade 7, thereby reducing the probability of the impurities in the lubricating liquid contacting and attaching to the shearing blade 7; When the shearing knife 7 moves downward, the air in the connecting frame 13 is blown toward the side of the shearing knife 7 through the blowing pipe 22. The impurities on the side of the shearing knife 7 can be preliminarily cleaned by the high-speed flowing air, thereby reducing the number of impurities on the shearing knife 7. When the shearing knife 7 moves upward, the lubricating liquid remaining on the side of the shearing knife 7 is blown downward by the air, thereby reducing the lubricating liquid content on the shearing knife 7, thereby reducing the probability of impurities adhering to the shearing knife 7 during subsequent shearing of the plate, further improving the cleaning effect of the shearing knife 7, and at the same time, the air is always blown toward the shearing knife 7 to cool it down, thereby ensuring a good cooling effect of the shearing knife 7 and reducing the wear of the shearing knife 7 itself.

[0033] like Figure 4-Figure 7 As shown, a shearing machine for manufacturing mechanical parts provided by the present invention is provided. A circulating pump 27 is fixedly installed on the mounting box 11. The circulating pump 27 is connected to a liquid extraction pipe 28. The liquid extraction pipe 28 extends into the mounting box 11 and a collecting hose 29 is connected to the end of the liquid extraction pipe 28. The collecting hose 29 is connected to the cleaning box 12. Both side walls of the cleaning box 12 are provided with a through groove 18 located between the first scraper 14 and the second scraper 15. The liquid outlet end of the circulating pump 27 is connected to the mounting box 11.

[0034] Specifically, a filter cartridge 30 is fixedly installed in the liquid extraction tube 28 , a rotating shaft 31 is rotatably installed at the end of the filter cartridge 30 , a fan blade 32 is fixedly installed on the rotating shaft 31 , a cleaning plate 33 is fixedly installed on the rotating shaft 31 , and the cleaning plate 33 is in sliding contact with the surface of the filter cartridge 30 .

[0035] Specifically, the liquid extraction pipe 28 is connected to a drop pipe 10, which passes through the side wall of the installation box 11 and a collecting cylinder 34 surrounding the drop pipe 10 is provided on the installation box 11. Impurities dropped from the filter cartridge 30 enter the collecting cylinder 34 through the drop pipe 10, and the collecting cylinder 34 is installed on the installation box 11 through the installation cylinder 35.

[0036] Specifically, a support plate 37 located in the collecting tube 34 is fixedly mounted on the mounting box 11, a threaded rod 38 is threadedly mounted on the support plate 37, a closing plate 39 for closing the end of the blanking tube 10 is fixedly mounted on the end of the threaded rod 38, a rotating tube 36 is rotatably mounted on the collecting tube 34, the rotating tube 36 and the threaded rod 38 are coaxially arranged, the threaded rod 38 extends into the rotating tube 36 and the two are in sliding contact, and the cross-section of the portion of the threaded rod 38 extending into the rotating tube 36 is a non-circular structure.

[0037] In actual application of this embodiment, in the initial state, the installation box 11 contains lubricating liquid and the liquid level of the lubricating liquid exceeds the height of the through groove 18. The circulation pump 27 extracts the lubricating liquid in the cleaning box 12 through the liquid extraction pipe 28 and the collection hose 29 and then transports the lubricating liquid to the installation box 11 again, so that the lubricating liquid in the installation box 11 circulates, and the lubricating liquid enters the cleaning box 12 from the through groove 18 and flows downward and flows out from the bottom of the cleaning box 12. When the shearing knife 7 is located in the cleaning box 12, the lubricating liquid flowing downward and the shearing knife 7 are The side surfaces generate frictional contact, and then the impurities on the side surfaces of the shearing blade 7 are further cleaned by the flow of the lubricating liquid. At the same time, the impurities that fall will be directly discharged outward from the cleaning box 12 along with the lubricating liquid, so as to prevent the impurities that fall from adhering to the shearing blade 7 again, thereby further improving the cleaning effect of the shearing blade 7. At the same time, the contact between the lubricating liquid and the shearing blade 7 can take away the heat on the shearing blade 7, accelerate the cooling of the shearing blade 7, make the shearing blade 7 always at a normal temperature, avoid the aggravated wear of the shearing blade 7 caused by high temperature, and further reduce the wear of the shearing blade 7 itself; When the lubricating oil flows in the liquid extraction pipe 28, the impurities carried in the lubricating oil are filtered through the filter cartridge 30. At the same time, when the lubricating oil flows, the fan blades 32 drive the rotating shaft 31 to rotate, and then the rotating shaft 31 drives the cleaning plate 33 to rotate. The cleaning plate 33 rotates to clean the filter cartridge 30 to prevent impurities from clogging the filter cartridge 30, ensuring that the lubricating oil always circulates stably. The fallen impurities pass downward through the drop pipe 10 into the collecting barrel 34. After long-term use, more impurities are accumulated in the collecting barrel 34. At this time, the rotating tube 36 is rotated to drive the threaded rod 38 to rotate through the rotating tube 36, so that the closing plate 39 The lower end of the closed blanking tube 10 is moved upward, and the impurities on the closing plate 39 are thrown off under the action of centrifugal force during the upward rotation of the closing plate 39, so as to avoid affecting the lower end of the subsequent closed blanking tube 10. Then, the collecting tube 34 can be removed for cleaning by rotating the collecting tube 34, and then installed on the mounting tube 35 again after cleaning, and then the closing plate 39 can be rotated in the opposite direction to release the sealing of the lower end of the blanking tube 10. This realizes the filtration and cleaning of impurities in the lubricating fluid at any time, reduces the content of impurities in the lubricating fluid, and is beneficial to improving the cleanliness of the shearing knife 7. When the lubricating fluid in the mounting box 11 is insufficient, it needs to be added in time.

[0038] like Figure 1-Figure 7 As shown, the present invention provides a method for using a shearing machine for manufacturing mechanical parts, which is applied to the above-mentioned shearing machine for manufacturing mechanical parts, and includes the following steps: Step S1: Add a sufficient amount of lubricating liquid into the installation box 11, place the plate on the base 1 and adjust it to the cutting position, and press and fix the plate by the fixing module 8; Step S2: according to the need of cutting the plate, the top plate 4 is driven to move by the first telescopic member 5, so as to adjust the position of the shearing knife 7, and then the second telescopic member 6 drives the shearing knife 7 to move downward to shear the plate; Step S3: After shearing, the shearing knife 7 continues to move downward into the cleaning box 12, and performs preliminary cleaning through the bubbles generated by the air in the cleaning chamber 20. At the same time, the circulating pump 27 drives the lubricating fluid in the cleaning box 12 to flow, and the shearing knife 7 is continuously flushed by the flow of the lubricating fluid. Then, the shearing knife 7 moves upward to scrape off the impurities and lubricating fluid on the side of the shearing knife 7 through the first scraper 14 and the second scraper 15, and the cleaning is completed; Step S4: When the circulation pump 27 extracts the lubricating fluid for circulation, the impurities in the lubricating fluid are filtered through the filter cartridge 30 and collected through the collecting cartridge 34. The impurities in the collecting cartridge 34 can be cleaned subsequently.
