Description

Technical Field

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention uses the first cutter and the second cutter to perform trimming processing from the top and the horizontal side of the trimmed product. Cutting from two directions is helpful to balance the force distribution during the cutting process and reduce the burrs and deformation of the non-ferrous metal caused by uneven force. This cutting method can more accurately control the cutting path and depth, thereby ensuring that the edges of the non-ferrous metals after cutting are flat and the sizes are accurate. The first cutter and the second cutter cut from the top and the horizontal side respectively, which is equivalent to cutting the non-ferrous metals from two directions at the same time, significantly shortening the cutting time; the two cutters act at the same time to share the load of a single cutting, making the cutting process smoother and improving the overall cutting efficiency.

[0019] 2. The present invention enables the trimmed product to move a certain distance through the rolling contact between the rolling wheel and the trimmed product, thereby avoiding the first cutter and the second cutter from squeezing the trimmed product due to their own thickness during trimming, thereby avoiding deformation of the trimmed product at the cutting portion during cutting; by allowing the cutting ends to move, it can be ensured that the cutter always maintains the best contact with the trimmed product during the cutting process, thereby reducing the deviation caused by squeezing and improving the cutting accuracy; allowing the cutting ends to move helps to ensure that each trimmed product is treated the same during the cutting process, thereby improving the consistency and quality stability between products.

[0020] 3. The present invention can effectively grind the trimmed edges of trimmed products through frictional contact with the friction wheel sleeve, remove possible defects such as burrs and flash, and improve the surface quality and smoothness of the products; grinding treatment helps to eliminate tiny cracks or stress concentration points that may be generated during the cutting process, thereby improving the overall quality and reliability of the products; combining the cutting and grinding processes together reduces the transfer time and cost of products between different processes, thereby improving the overall production efficiency.

[0021] 4. The gas ejected from the jet hole of the present invention diffuses the cutting fluid, which can increase the contact area between the cutting fluid and the non-ferrous metal, thereby enhancing the cooling effect; this helps to reduce the heat generated during the cutting process and reduce the deformation of the workpiece due to thermal deformation; the full diffusion of the cutting fluid can also improve the lubrication conditions during the cutting process and reduce the friction between the tool and the workpiece. This helps to reduce the cutting force and further reduce the possibility of deformation of the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The present invention provides a technical solution:

[0038] See also Figure 1 , Figure 5 , Figure 6 , Figures 9 to 11 A trimming die for producing nonferrous metal products comprises a supporting base 1, a trimming die 2 is fixedly mounted on the upper end surface of the supporting base 1, an assembly die groove 3 is provided inside the trimming die 2, a trimming product 4 is matched and mounted inside the assembly die groove 3, and a cleaning trimming opening 10 is provided at the bottom of the middle position inside the supporting base 1 and the trimming die 2.

[0039] The trimming die 2 is provided with a slitting assembly 5 on the inside and outside. The slitting assembly 5 includes a driving main board 501 movably arranged on the top surface of the trimming die 2. A first cutter 502 is fixedly installed on the left side of the bottom end of the driving main board 501. A driving bottom plate 504 is fixedly installed on the right side of the bottom end of the driving main board 501. A trimming driven plate 506 corresponding to the driving bottom plate 504 is slidably installed inside the trimming die 2. A positioning top block 505 is fixedly installed on the left side wall of the driving bottom plate 504. The right side wall of the trimming driven plate 506 A positioning engaging groove 507 is provided on the top and engages with the positioning top block 505. A second cutter 508 is fixedly installed on the left side of the trimming driven plate 506. The slitting assembly 5 also includes a first driving side plate 503 fixedly installed at the bottom of the front and rear ends of the driving main board 501. Second driving side plates 510 are fixedly installed on the right sides of the front and rear walls of the trimming driven plate 506. A return spring 509 is fixedly installed on the side wall of the second driving side plate 510 away from the trimming product 4, and a plurality of return springs 509 are arranged at equal intervals.

[0040] By adopting the above technical solution, when in use, the trimming product 4 matching the assembly mold groove 3 is inserted into the assembly mold groove 3. When trimming is required, the driving main board 501 is connected to the driving device, so that the driving main board 501 has sufficient power to trim the trimming product 4. When the driving main board 501 moves downward, the driving main board 501 can drive the first cutter 502 to move downward, so that the first cutter 502 can trim one side of the trimming product 4. At the same time, when the driving main board 501 moves downward, it can also drive the driving bottom plate 504 to move downward, so that the driving bottom plate 504 can push the positioning top block 505 to move downward. Through the mutual engagement of the positioning top block 505 and the positioning engaging groove 507, the trimming driven plate 506 can be pushed to move to the side close to the trimming product 4. The movement of the trimming driven plate 506 can drive the second cutter 508 to trim the trimming product 4 is trimmed on the side, so that the first cutter 502 and the second cutter 508 can perform trimming processing from the top and the horizontal side of the trimmed product 4. Cutting from two directions in this way is helpful to balance the force distribution during the cutting process and reduce the burrs and deformation of the non-ferrous metal caused by uneven force; this cutting method can more accurately control the cutting path and depth, so as to ensure that the edge of the non-ferrous metal after cutting is flat and the size is accurate; the cooperation of the first cutter 502 and the second cutter 508 makes the cutting process more stable and reduces the tool damage or cutting deviation caused by excessive force on a single tool; the first cutter 502 and the second cutter 508 cut from the top and the horizontal side respectively, which is equivalent to cutting the non-ferrous metal from two directions at the same time, which significantly shortens the cutting time; the two cutters act at the same time to share the load of a single cutting, making the cutting process smoother and improving the overall cutting efficiency. When the trimming follower plate 506 moves toward the side close to the trimming product 4, the trimming follower plate 506 can drive the second driving side plate 510 and the first driving side plate 503 to move. At the same time, the moving second driving side plate 510 will drive the reset spring 509 to stretch, thereby storing energy through the reset spring 509, which facilitates the reset processing of the second driving side plate 510.

[0041] Specifically, Figures 1 to 5 and Fig. 9As shown, the trimming die 2 is provided with a pneumatic drive assembly 6 inside and outside, which includes an air bag 601 fixedly installed on the left side wall of the second drive side plate 510 and the bottom end surface of the first drive side plate 503, and the end of the air bag 601 away from the drive main board 501 is fixedly connected with a connecting bag tube 602, and a control valve 603 is fixedly installed on the outer wall of the connecting bag tube 602; the trimming die 2 is provided with a rolling friction assembly 7, which includes an assembly frame 701 fixedly installed on the side wall of the air bag 601 close to the trimming product 4, and a rotating shaft 702 is rotatably installed at the bottom end of the assembly frame 701, and the number of rotating shafts 702 is equidistantly arranged. Rolling wheels 703 are fixedly installed at the middle position of the outer wall of the plurality of rotating shafts 702, and friction wheel sleeves 704 are embedded on the outer wall of the rolling wheel 703, and the friction wheel sleeves 704 and the trimming product 4 are mutually fitted.

[0042] By adopting the above technical solution, the control valve 603 can be opened, so that gas can be introduced into the airbag 601 through the connecting bag tube 602, so that the air pressure in the airbag 601 can be controlled, and the inflated airbag 601 can squeeze the assembly frame 701, so that the rolling wheel 703 on the assembly frame 701 can contact with the trimmed product 4. When trimming, the second driving side plate 510 and the first driving side plate 503 can compress the airbag 601. It should be noted that the compression distance of the airbag 601 must match the cutting distance of the first cutter 502 and the second cutter 508 for the trimmed product 4. When the airbag 601 is compressed during trimming, the airbag 601 is compressed during trimming. When the airbag 601 is compressed, the assembly rack 701 will be further squeezed. The assembly rack 701 can further compress the side of the trimmed product 4 through the rolling wheel 703. The trimmed product 4 and the assembly die groove 3 are closely fitted to ensure the stability of the trimmed product 4 in the cutting direction during trimming. As the cutting progresses, the non-ferrous metal material is more tightly fixed, which enables the tool to cut the material more smoothly, reducing the cutting resistance and cutting time. At the same time, the stable fixing effect also helps to maintain the sharpness of the tool and further improve the cutting efficiency. As the cutting progresses, the non-ferrous metal material is more firmly fixed, which can effectively reduce the error caused by material shaking or displacement. This tightening effect can ensure the stability and accuracy of the cutting process, thereby improving the processing accuracy. During the cutting process, if the non-ferrous metal is not fixed stably, it may cause material splashing or tool damage, thereby causing safety accidents. The stable fixing effect can reduce the vibration and wear of the cutting equipment during the processing, thereby extending the service life of the equipment.

[0043] During the trimming process, as the cutting progresses, the first cutter 502 and the second cutter 508 will extend into the interior of the trimmed product 4. The first cutter 502 and the second cutter 508 themselves have a certain thickness, so that the thickness of the first cutter 502 and the second cutter 508 themselves will cause a certain amount of extrusion on the trimmed product 4. When the trimmed product 4 is extruded during cutting, the trimmed product 4 can be rolled in contact with the trimmed product 4 by the rolling wheel 703 under the action of the separation extrusion force, so that the trimmed product 4 moves a certain distance, thereby avoiding the first cutter 502 and the second cutter 508 The thickness of the self-extrusion causes the trimmed product 4 to be squeezed during trimming, thereby preventing the trimmed product 4 from being cut during cutting. The cutting part is deformed; by allowing the two cutting ends to move, it can be ensured that the cutter always maintains the best contact with the trimmed product 4 during the cutting process, thereby reducing the deviation caused by extrusion and improving the cutting accuracy; allowing the two cutting ends to move helps to ensure that each trimmed product 4 is treated the same during the cutting process, thereby improving the consistency and quality stability between products; continuous extrusion may cause the cutter to wear faster. Allowing the two cutting ends to move can reduce unnecessary friction between the cutter and the trimmed product 4, thereby extending the service life of the cutter and reducing the frequency and cost of replacement; reducing deformation and errors in the cutting process means less rework and inspection time, thereby improving overall production efficiency.

[0044] After the trimming is completed, the inflated airbag 601 squeezes the assembly frame 701, so that the rolling wheel 703 on the assembly frame 701 contacts with the trimmed product 4. When the trimmed product 4 is moved and replaced, the friction wheel sleeve 704 on the rolling wheel 703 needs to contact and rub with the cutting edge of the trimmed product 4, so that the cutting edge position of the trimmed product 4 can be polished through the friction between the trimmed product 4 and multiple friction wheel sleeves 704. In this way, through the friction contact with the friction wheel sleeve 704, the cutting edge of the trimmed product 4 can be effectively polished to remove possible defects such as burrs and flash, thereby improving the surface quality and smoothness of the product; the polishing process helps to eliminate tiny cracks or stress concentration points that may be generated during the cutting process, thereby improving the overall quality and reliability of the product; combining the two processes of cutting and polishing together reduces the transfer time and cost of the product between different processes, thereby improving the overall production efficiency; the polished cutting edge is smoother and neater, which helps to improve the aesthetics and applicability of the product and meet a wider range of customer needs.

[0045] Specifically, Figure 2 , Figure 3 , Figure 4 , Figure 7 and Fig. 9As shown, a cleaning component 8 is provided inside the trimming die 2, and the cleaning component 8 includes a cleaning assembly chamber 804 opened inside the trimming die 2, and the cleaning assembly chamber 804 is located below the trimming product 4. A driving spindle 801, a cleaning belt 802 and a bearing sub-shaft 803 are rotatably installed inside the cleaning assembly chamber 804. The driving spindle 801 is arranged near the middle position of the trimming die 2, and the number of the bearing sub-shafts 803 is arranged in plurality and is equidistant from the middle position of the trimming die 2. The cleaning belt 802 is sleeved on the outside of the driving spindle 801 and the bearing sub-shaft 803 near the port position of the assembly die groove 3; the left end of the rotating shaft 702 near the port position of the assembly die groove 3 is fixedly installed with The third transmission shaft 810, the left end of the third transmission shaft 810 is fixedly installed with a third bevel gear 811, the interior of the trimming die 2 is fixedly installed with an assembly shaft frame 809, the interior of the assembly shaft frame 809 is rotatably installed with a second transmission shaft 807 corresponding to the third bevel gear 811, the upper and lower ends of the second transmission shaft 807 are fixedly installed with second bevel gears 808, the upper second bevel gear 808 and the third bevel gear 811 are meshed with each other, the left end of the driving main shaft 801 is fixedly connected with the first transmission shaft 805, the left end of the first transmission shaft 805 is fixedly connected with the first bevel gear 806, the first bevel gear 806 and the second bevel gear 808 are meshed with each other.

[0046] By adopting the above technical solution, when the friction wheel sleeve 704 and the trimmed product 4 rotate frictionally, the rolling wheel 703 and the rotating shaft 702 can be driven to rotate on the assembly frame 701. At this time, the rotating rotating shaft 702 can drive the third transmission shaft 810 to rotate. The rotation of the third transmission shaft 810 can drive the third bevel gear 811 to rotate. The third bevel gear 811 and the second bevel gear 808 at the upper end are meshed with each other, thereby driving the second transmission shaft 807 to rotate on the assembly shaft frame 809. The assembly shaft frame 809 can support the rotation of the second transmission shaft 807. The second bevel gear 808 at the bottom of the second transmission shaft 807 rotates together, and the second bevel gear 808 and the third bevel gear 811 are meshed with each other, thereby driving the first transmission shaft 805 to rotate. The rotation of the first transmission shaft 805 can drive the driving main The shaft 801 rotates, and the outer side of the driving main shaft 801 and the bearing secondary shaft 803 is sleeved with a cleaning belt 802, so that the cleaning belt 802 can be driven to rotate. The multiple bearing secondary shafts 803 can support the cleaning belt 802, so as to avoid the cleaning belt 802 being placed above the trimming product 4 not being able to provide a good support effect. The cleaning belt 802 can make the burrs and other debris dropped by friction rotate and move with the cleaning belt 802 when rotating, so that the burrs and other debris produced by friction can be moved to the port of the assembly mold groove 3 or the cleaning trimming port 10 through the transportation of the cleaning belt 802, so that the burrs and other debris can be easily cleaned. The accumulation of debris not only affects the stability of the fixation during trimming, but also may become a safety hazard; the debris is removed from the working area by the cleaning belt 802, so that the working environment can be kept clean and safe. The design of the cleaning belt 802 usually takes into account the convenience of operation, making the cleaning work simple and quick. This can not only improve the efficiency of operators, but also reduce their labor intensity.

[0047] Specifically, Figure 3 , Figure 4 and Figure 8As shown, a spray assembly 9 is provided at a position near the cleaning trimming opening 10 inside the trimming die 2, and the spray assembly 9 includes a pressurized air chamber 909 opened inside the trimming die 2, the pressurized air chamber 909 is connected to the air bag 601 located above the front end of the trimming product 4, and an air guide tube 910 is fixedly connected between the air bag 601 and the pressurized air chamber 909; the rear end of the pressurized air chamber 909 is respectively provided with a cutting liquid chamber 902 and an air pressure push chamber 906 opened inside the trimming die 2, the air pressure push chamber 906 is located below the cutting liquid chamber 902, and the cutting liquid chamber 902 is connected to the air pressure push chamber 906. A partition plate 905 is fixedly installed between the pressure push chamber 906, a second diaphragm 908 is fixedly installed between the air pressure push chamber 906 and the boost air chamber 909, and a jet hole 907 which is interconnected with the cleaning trimming port 10 is opened at the rear end of the air pressure push chamber 906; a first diaphragm 903 is fixedly installed between the cutting liquid chamber 902 and the boost air chamber 909, a nozzle 904 which is interconnected with the cleaning trimming port 10 is fixedly installed at the rear end of the cutting liquid chamber 902, and the upper end of the cutting liquid chamber 902 is connected to a one-way filling valve tube 901 which passes through the outer wall of the top end of the trimming die 2.

[0048] By adopting the above technical solution, during trimming, the airbag 601 is squeezed, and the gas inside the airbag 601 can be introduced into the pressurized air chamber 909 through the air guide tube 910. The air pressure in the pressurized air chamber 909 increases, so that the first diaphragm 903 and the second diaphragm 908 can be squeezed. The one-way filling valve tube 901 is interconnected with the external cutting liquid supply structure, so that the cutting liquid can be added to the cutting liquid chamber 902 through the one-way filling valve tube 901. The first diaphragm 903 on one side of the cutting liquid chamber 902 is squeezed and deformed, so that the injected cutting liquid in the cutting liquid chamber 902 can be pushed to the trimming part of the trimmed product 4 through the nozzle 904. The cutting liquid sprayed on the trimmed product 4 can absorb and take away the liquid generated during the cutting process. Heat can significantly reduce the temperature of the cutting area, thereby protecting the tool and workpiece from high temperature damage; by lowering the temperature, the cutting fluid can reduce the wear of the tool and the deformation of non-ferrous metal products. The cutting fluid can penetrate into the contact surface between the tool and the workpiece to form a lubricating film, reduce or avoid direct contact, thereby reducing friction and cutting force; good lubrication can reduce the extrusion and friction of the tool on the workpiece, reduce the roughness of the workpiece surface, and improve processing accuracy and surface quality; the cutting fluid can smoothly wash away the metal chips, powder and other debris generated during the cutting process to prevent them from clogging the tool or scratching the workpiece surface; by lowering the temperature, reducing friction and cleaning debris, the cutting fluid can significantly improve the production efficiency of non-ferrous metal trimming. When the second diaphragm 908 is squeezed, the second diaphragm 908 deforms to squeeze the air pressure push chamber 906, so that the gas in the air pressure push chamber 906 can be squeezed out through the jet hole 907. The gas ejected from the jet hole 907 can diffuse the cutting fluid ejected from the nozzle 904. The gas diffusion effect allows the cutting fluid to cover the cutting part more evenly, ensuring that each area that needs cooling and lubrication can get sufficient cutting fluid. The diffusion effect helps to reduce the blind areas that the cutting fluid cannot reach, ensuring that the entire cutting process can be well cooled and lubricated; the gas ejected from the jet hole 907 diffuses the cutting fluid, which can increase the contact area between the cutting fluid and the non-ferrous metal, thereby enhancing the cooling effect; this helps to reduce the heat generated during the cutting process and reduce the deformation of the workpiece due to thermal deformation; the full diffusion of the cutting fluid can also improve the lubrication conditions during the cutting process and reduce the friction between the tool and the workpiece; this helps to reduce the cutting force and further reduce the possibility of deformation of the workpiece.

[0049] Working principle: When in use, the trimming product 4 that matches the assembly mold groove 3 is inserted into the assembly mold groove 3, and the control valve 603 is opened, so that gas can be introduced into the airbag 601 through the connecting bag tube 602, so that the air pressure in the airbag 601 can be controlled, and the inflated airbag 601 can squeeze the assembly frame 701, so that the rolling wheel 703 on the assembly frame 701 can contact with each other. When trimming is required, the driving main board 501 and the driving device are connected to each other, so that the driving main board 501 has sufficient power to trim the trimming product 4. When the driving main board 501 moves downward, the driving main board 501 can drive the first cutter 502 to move downward, so that the first cutter 502 can trim one side of the trimming product 4. At the same time, when the driving main board 501 moves downward, it can also drive the driving bottom plate 504 to move downward. The second drive side plate 510 and the first drive side plate 503 are moved in a direction that the first drive side plate 510 and the second drive side plate 503 are moved in a direction that the first drive side plate 510 and the second drive side plate 503 are moved in a direction that the first drive side plate 510 and the second drive side plate 503 are moved in a direction that the first drive side plate 510 and the second drive side plate 503 are moved in a direction that the first drive side plate 510 and the second drive side plate 503 are moved in a direction that the first drive side plate 510 and the second drive side plate 503 are moved in a direction that the first drive side plate 510 and the second drive side plate 503 are moved in a direction that the first drive side plate 510 and the second drive side plate 503 are moved in a direction that the first drive side plate 510 and the second drive side plate 503 are moved in a direction that the first drive side plate 510 and the second drive side plate 510 ...

[0050] Secondly, when trimming, the second driving side plate 510 and the first driving side plate 503 can compress the airbag 601. It should be noted that the compression distance of the airbag 601 must match the cutting distance of the first cutter 502 and the second cutter 508 on the trimmed product 4. When the airbag 601 is compressed during trimming, the airbag 601 will further squeeze the assembly rack 701, and the assembly rack 701 can further compress the side of the trimmed product 4 through the rolling wheel 703. The trimmed product 4 is closely fitted with the assembly die groove 3, thereby ensuring the stability of the trimmed product 4 in the cutting direction during trimming. During the trimming process, As the cutting progresses, the first cutter 502 and the second cutter 508 will extend into the interior of the trimmed product 4. The first cutter 502 and the second cutter 508 themselves have a certain thickness, so the thickness of the first cutter 502 and the second cutter 508 themselves will cause a certain amount of extrusion on the trimmed product 4. When the trimmed product 4 is extruded during cutting, the trimmed product 4 can be moved a certain distance through the rolling contact between the rolling wheel 703 and the trimmed product 4 under the action of the separation and extrusion force, thereby avoiding the extrusion of the trimmed product 4 caused by the thickness of the first cutter 502 and the second cutter 508 themselves during cutting.

[0051] At the same time, the airbag 601 is squeezed, and the gas inside the airbag 601 can be introduced into the boosting air chamber 909 through the air guide tube 910. The air pressure in the boosting air chamber 909 increases, so that the first diaphragm 903 and the second diaphragm 908 can be squeezed. The one-way filling valve tube 901 is interconnected with the external cutting liquid supply structure, so that the cutting liquid can be added to the cutting liquid chamber 902 through the one-way filling valve tube 901. The first diaphragm 903 on one side of the cutting liquid chamber 902 is squeezed and deformed, so that the injected cutting liquid in the cutting liquid chamber 902 can be pushed to the trimming part of the trimming product 4 through the nozzle 904. When the second diaphragm 908 is squeezed, the second diaphragm 908 is deformed to squeeze the air pressure push chamber 906, so that the gas in the air pressure push chamber 906 can be squeezed out through the jet hole 907. The gas ejected from the jet hole 907 can have a diffusion effect on the cutting fluid ejected from the nozzle 904.

[0052] Finally, after the trimming is completed, the inflated airbag 601 squeezes the assembly frame 701, so that the rolling wheel 703 on the assembly frame 701 contacts with the trimmed product 4. When the trimmed product 4 is moved and replaced, the friction wheel sleeve 704 on the rolling wheel 703 is required to contact and rub with the trimmed edge of the trimmed product 4, so that the trimmed edge position of the trimmed product 4 can be polished through the friction between the trimmed product 4 and multiple friction wheel sleeves 704. When the friction wheel sleeve 704 and the trimmed product 4 rotate with each other, the rolling wheel 703 and the rotating shaft 702 can be driven to rotate on the assembly frame 701. At this time, the rotating rotating shaft 702 can drive the third transmission shaft 810 to rotate. The rotation of the third transmission shaft 810 can drive the third bevel gear 811 to rotate. The third bevel gear 811 is meshed with the second bevel gear 808 at the upper end, thereby driving the second transmission shaft 810 to rotate. The moving shaft 807 rotates on the assembly shaft frame 809, and the assembly shaft frame 809 can support and bear the rotation of the second transmission shaft 807. The second bevel gear 808 at the bottom end of the second transmission shaft 807 rotates therewith, and the second bevel gear 808 and the third bevel gear 811 are meshed with each other, thereby driving the first transmission shaft 805 to rotate. The rotation of the first transmission shaft 805 can drive the driving main shaft 801 to rotate. The outer sides of the driving main shaft 801 and the bearing secondary shaft 803 are sleeved with a cleaning belt 802, thereby driving the cleaning belt 802 to rotate. The set cleaning belt 802 can make the burrs and other debris dropped by friction rotate and move with the cleaning belt 802 when rotating. In this way, the burrs and other debris generated by friction can be moved to the port of the assembly mold groove 3 or the cleaning cutting edge 10 through the transportation of the cleaning belt 802, which can facilitate the cleaning of the burrs and other debris.
