Description

Technical Field

[0001] This utility model relates to the field of rolled bushing processing technology, specifically a rolling die for bimetallic rolled bushing processing. Background Technology

[0002] Rolled bushings are strip-shaped metal components used in sliding bearings. They are formed through a rolling process and have unique structural features and performance advantages. During the processing of rolled bushings, a rolling die is required.

[0003] Existing rolling dies for bimetallic rolled bushings can cut and roll metal sheets into bushings, but they are limited in their ability to process bushings of a single size. When processing bushings of different sizes, the entire rolling die must be replaced. Existing rolling dies are inconvenient because they cannot process bushings of different sizes. Therefore, we propose a new rolling die for bimetallic rolled bushings to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a rolling die for processing bimetallic rolled bushings, so as to solve the problems currently found in the market as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rolling die for processing bimetallic rolled bushings, comprising a base, a top frame provided on the top of the base, and the base and the top frame being fixedly connected at their four corners by support rods, wherein... A mounting frame is provided below the top frame. The mounting frame is raised and lowered by a lifting mechanism. An upper mold is installed at the bottom of the mounting frame by bolts. A shearing block is fixedly connected to one end of the upper mold. A lower mold is installed at the top of the base corresponding to the top of the upper mold by bolts. A baffle and a material threading frame are respectively provided at the top of the base near the two ends of the lower mold. A material threading groove is provided through the upper side of the material threading frame. A sliding groove is provided at the top of the base corresponding to the baffle and the material threading frame. A slider is fixedly connected to the bottom of the sliding groove of the baffle and the material threading frame. A screw threadedly connected to the slider is rotatably connected inside the sliding groove. A motor is installed at one end of the base, and the motor shaft is fixedly connected to a lead screw. A lifting frame is provided on the top of the base near the lower die. Guide frames are symmetrically fixedly connected to both ends of the lifting frame. A guide rod groove runs through the middle of the guide frame. A guide rod is fixedly connected to the top of the base corresponding to the guide frame. A first spring is sleeved on the guide rod between the guide frame and the base. A winding roller is installed on the side of the lifting frame corresponding to the upper die and the lower die by bolt connection. A winding groove is opened on the side of the upper die and the lower die corresponding to the winding roller. A pressing mechanism is provided at the bottom of the upper die corresponding to the winding groove. A pushing mechanism for unloading is provided on the lifting frame.

[0006] Preferably, the lifting mechanism includes a first hydraulic rod, which is installed at the center of the top of the top frame. The top frame has symmetrical guide grooves on both sides near the mounting frame, and the mounting frame has a guide rod fixedly connected to the top of the guide groove.

[0007] Preferably, the lead screw is provided with two opposite external threads, and the two opposite external threads are located in the sliding grooves on both sides respectively.

[0008] Preferably, the pressing mechanism includes a pressure plate groove, the upper die has a pressure plate groove at the bottom corresponding to the rolling groove, the upper die has a push rod groove at the top corresponding to the pressure plate groove, a push rod passes through the push rod groove, a second spring is installed between the push rod and the top of the inner side of the push rod groove, and a pressure plate is fixedly connected to the bottom end of the push rod.

[0009] Preferably, the push rod is a rectangular column, and the external dimensions of the push rod match the internal dimensions of the push rod groove.

[0010] Preferably, the pressure plate is an arc-shaped plate, and the inner diameter of the pressure plate is equal to the inner diameter of the rolling groove, and the outer dimensions of the pressure plate match the inner dimensions of the pressure plate groove.

[0011] Preferably, the pushing mechanism includes a second hydraulic rod, and the second hydraulic rods are symmetrically installed on both sides of the lifting frame. A pushing plate is installed at the telescopic end of the second hydraulic rod. A push rod groove is opened on the side of the pushing plate near the rolling roller. A third spring is installed in the push rod groove, and a push rod is installed on the side of the third spring near the opening of the push rod groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, during the operation of the rolling die, the feeding device pushes the metal sheet between the upper and lower dies. After the end of the metal sheet abuts against the stop, the lifting mechanism controls the upper die to move downward. The upper die drives the shearing block to descend synchronously. The shearing block and the material threading frame form a shearing force to cut the metal sheet. At the same time, the pressing mechanism presses down on the metal sheet. As the upper die continues to descend, it works with the lower die and the rolling roller to compress the metal sheet onto the outside of the rolling roller. The pushing mechanism pushes the workpiece wrapped around the outside of the rolling roller down. The upper die, lower die, and rolling roller are all detachably installed by bolts to the mounting frame, base, and lifting frame, respectively, allowing for replacement of the upper die, lower die, and rolling roller. When the motor is working, the lead screw and slider can move the two side stops and the material threading frame closer or further apart, adjusting the distance between the stops and the material threading frame. This allows for the processing of bushings of different sizes, effectively improving the applicability of the rolling die.

[0013] In this invention, after the metal sheet is wound around the outside of the winding roller, the end of the push rod abuts against the side of the winding roller via a third spring. The pusher plate is moved by the second hydraulic rod, causing the pusher plate to push the bushing on the outside of the winding roller via the push rod, so that the bushing falls off the end of the winding roller. This pushing mechanism allows the end of the push rod to always abut against the winding roller via the third spring, thus making it suitable for winding rollers of different sizes, so as to complete the unloading when processing bushings of different sizes.

[0014] In this invention, when the mounting frame moves the upper die downward, the upper die first presses against the metal plate through the pressure plate. The pressure plate and the rolling roller limit the metal plate, preventing the cut metal plate from shaking when it is cut by the shearing block and the material threading frame. As the upper die continues to move downward, the pressure plate retracts into the pressure plate groove to overcome the elastic force of the second spring, preventing the pressure plate from causing obstruction when rolling the metal plate.

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.

[0018] Please see Figures 1 to 7 This utility model provides a technical solution: a rolling die for processing bimetallic rolled bushings, including a base 1, a top frame 2 provided on the top of the base 1, and the base 1 and the top frame 2 being fixedly connected at their four corners by support rods 3. A mounting frame 4 is provided below the top frame 2. The mounting frame 4 is raised and lowered by a lifting mechanism. An upper mold 8 is installed at the bottom of the mounting frame 4 by bolts. A shearing block 9 is fixedly connected to one end of the bottom of the upper mold 8. A lower mold 10 is installed at the top of the base 1 corresponding to the top of the upper mold 8 by bolts. A baffle 11 and a material passer 12 are respectively provided at the top of the two ends of the base 1 near the lower mold 10. A material passer 13 passes through the material passer 12 on the side near the top. A sliding groove 14 is opened at the top of the base 1 corresponding to the baffle 11 and the material passer 12. A slider 15 is fixedly connected to the bottom of the baffle 11 and the material passer 12 corresponding to the sliding groove 14. A screw rod 16 that is threadedly connected to the slider 15 is rotatably connected inside the sliding groove 14. A motor 17 is installed at one end of the base 1. The shaft of the motor 17 is fixedly connected to the lead screw 16. A lifting frame 18 is provided on the top of the base 1 near the lower mold 10. Guide frames 19 are symmetrically fixedly connected to both ends of the lifting frame 18. A guide rod groove 20 passes through the middle of the guide frame 19. A guide rod 21 is fixedly connected to the top of the base 1 corresponding to the guide frame 19. A first spring 22 is sleeved on the guide rod 21 between the guide frame 19 and the base 1. A winding roller 23 is installed on the side of the lifting frame 18 corresponding to the upper mold 8 and the lower mold 10 by bolt connection. A winding groove 24 is opened on the side of the upper mold 8 and the lower mold 10 corresponding to the winding roller 23. A pressing mechanism is provided at the bottom of the upper mold 8 corresponding to the winding groove 24. A pushing mechanism for unloading is provided on the lifting frame 18. During the operation of the rolling die, the feeding device pushes the metal sheet between the upper die 8 and the lower die 10. After the end of the metal sheet abuts against the stop 11, the lifting mechanism controls the upper die 8 to move downward. The upper die 8 drives the shearing block 9 to descend synchronously. The shearing block 9 and the material threading frame 12 form a shearing force to cut the metal sheet. At the same time, the pressing mechanism presses down on the metal sheet. As the upper die 8 continues to descend, it works with the lower die 10 and the rolling roller 23 to compress the metal sheet and roll it around the outside of the rolling roller 23. The pushing mechanism then pushes the outer edge of the rolling roller 23... The workpiece is pushed down from the side. The upper die 8, lower die 10, and rolling roller 23 are all detachably installed by bolts to the mounting frame 4, base 1, and lifting frame 18, respectively. The upper die 8, lower die 10, and rolling roller 23 can be replaced. When the motor 17 is working, it can drive the side stops 11 and the material feeder 12 to move closer or further apart through the lead screw 16 and slider 15, adjusting the distance between the stop 11 and the material feeder 12. This allows for the processing of bushings of different sizes, effectively improving the applicability of the rolling die.

[0019] Please see Figures 1 to 7 The lifting mechanism includes a first hydraulic rod 5. The first hydraulic rod 5 is installed at the top center of the top of the top frame 2. The top frame 2 has guide grooves 6 symmetrically opened on both sides near the mounting frame 4. The mounting frame 4 is fixedly connected to the top of the guide grooves 6. The lead screw 16 has two opposite external threads, and the two opposite external threads of the lead screw 16 are located in the sliding grooves 14 on both sides. When the first hydraulic rod 5 is working, it drives the mounting frame 4 to lift and lower. When the mounting frame 4 lifts and lowers, it drives the guide rod 7 to lift and lower synchronously. Through the guide structure formed by the guide rod 7 and the guide groove 6, the lifting and lowering of the mounting frame 4 can be guided to avoid the lifting and lowering of the mounting frame 4 from deviating.

[0020] Please see Figures 1 to 7The pressing mechanism includes a pressure plate groove 25. The upper die 8 has a pressure plate groove 25 at the bottom corresponding to the rolling groove 24. The upper die 8 has a push rod groove 26 connected to the top of the pressure plate groove 25. A push rod 27 passes through the push rod groove 26. A second spring 28 is installed between the push rod 27 and the top of the inner side of the push rod groove 26. A pressure plate 29 is fixedly connected to the bottom end of the push rod 27. The push rod 27 is a rectangular column, and the external dimensions of the push rod 27 match the internal dimensions of the push rod groove 26. The pressure plate 29 is an arc-shaped plate, and the inner diameter of the pressure plate 29 matches the inner diameter of the rolling groove 24. The dimensions of the pressure plate 29 are equal to those of the pressure plate groove 25. When the mounting frame 4 moves the upper mold 8 downward, the upper mold 8 first presses against the metal plate through the pressure plate 29. The pressure plate 29 and the rolling roller 23 limit the metal plate to prevent the cut metal plate from shaking when the metal plate is cut by the shearing block 9 and the material feeding frame 12. As the upper mold 8 continues to move downward, the pressure plate 29 overcomes the elastic force of the second spring 28 and retracts into the interior of the pressure plate groove 25 to prevent the pressure plate 29 from causing obstruction when the metal plate is rolled.

[0021] Please see Figures 1 to 7 The pushing mechanism includes a second hydraulic rod 30. The second hydraulic rod 30 is symmetrically installed on both sides of the lifting frame 18. A pushing plate 31 is installed at the telescopic end of the second hydraulic rod 30. A push rod groove 32 is opened on the side of the pushing plate 31 near the rolling roller 23. A third spring 33 is installed in the push rod groove 32. A push rod 34 is installed on the side of the third spring 33 near the opening of the push rod groove 32. After the metal plate is rolled on the outside of the rolling roller 23, the end of the push rod 34 abuts against the side of the rolling roller 23 through the third spring 33. The second hydraulic rod 30 pushes the pushing plate 31 to move, so that the pushing plate 31 pushes the bushing on the outside of the rolling roller 23 through the push rod 34, so that the bushing falls off the end of the rolling roller 23. In this pushing mechanism, the end of the push rod 34 can always abut against the rolling roller 23 through the third spring 33, so that it can be applied to rolling rollers 23 of different sizes, so as to complete the unloading when processing bushings of different sizes.

[0022] Working Principle: This is a rolling die for processing bimetallic rolled bushings. During operation, the feeding device pushes the metal sheet between the upper die 8 and the lower die 10. After the end of the metal sheet abuts against the stop frame 11, the lifting mechanism controls the upper die 8 to move downwards. The upper die 8 drives the shearing block 9 to descend synchronously. The shearing block 9 and the material threading frame 12 generate shearing force, cutting the metal sheet. Simultaneously, the pressing mechanism presses down on the metal sheet. As the upper die 8 continues to descend, it works in conjunction with the lower die 10 and the rolling roller 23, pressing the metal sheet onto the outside of the rolling roller 23. The pushing mechanism pushes the workpiece sleeved on the outside of the rolling roller 23 down. The upper die 8, lower die 10, and rolling roller 23 are all detachably installed by bolts to the mounting frame 4, base 1, and lifting frame 18, respectively, which allows the upper die 8, lower die 10, and rolling roller 23 to be replaced. When the motor 17 is working, it can drive the two side stops 11 and the material passing frame 12 to move closer or further apart through the lead screw 16 and slider 15, adjusting the distance between the stop 11 and the material passing frame 12, thereby enabling the processing of bushings of different sizes and effectively improving the applicability of the rolling die. When the first hydraulic rod 5 is working, it drives the mounting frame 4 to rise and fall. When the mounting frame 4 rises and falls, it drives the guide rod 7 to rise and fall synchronously. The guide structure formed by the guide rod 7 and the guide groove 6 can guide the rise and fall of the mounting frame 4 and prevent the mounting frame 4 from deviating during the rise and fall. When the mounting frame 4 drives the upper die 8 to move downward, the upper die 8 first abuts against the metal plate through the pressure plate 29. The pressure plate 29 and the rolling roller 23 limit the metal plate and prevent the cut metal plate from shaking when it is cut by the shearing block 9 and the material feeding frame 12. As the upper die 8 continues to move downward, the pressure plate 29 retracts against the elastic force of the second spring 28. Inside the pressure plate groove 25, the pressure plate 29 is prevented from obstructing the rolling of the metal sheet. After the metal sheet is rolled on the outside of the rolling roller 23, the end of the push rod 34 abuts against the side of the rolling roller 23 through the third spring 33. The pusher plate 31 is pushed to move by the second hydraulic rod 30, so that the pusher plate 31 pushes the bushing on the outside of the rolling roller 23 through the push rod 34, so that the bushing falls off the end of the rolling roller 23. This pushing mechanism, in which the end of the push rod 34 can always abut against the rolling roller 23 through the third spring 33, can be applied to rolling rollers 23 of different sizes, so as to complete the unloading when processing bushings of different sizes.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
