Description

Technical Field

[0001] This invention belongs to the technical field of mold processing, specifically a precision polishing device for deep drawing mold parts. Background Technology

[0002] In the field of deep drawing die parts manufacturing, this device mainly utilizes a vibrating tank containing abrasive sand of specific specifications. Driven by a motor, it generates high-frequency, regular vibrations, causing continuous and gentle relative motion between the abrasive sand and the workpiece. During this process, the abrasive sand performs uniform, all-around micro-cutting and rolling on the surface of the die parts, effectively removing tool marks, burrs, and micro-irregularities left from previous processes, gradually improving surface finish.

[0003] Patent document CN116276611A describes a vibratory polishing machine, including a frame and a vibrating component located inside the frame. A drive motor 1 and a drive motor 2 are fixed on the frame, and a rotating shaft is vertically arranged. A turntable is fixed to the lower end of the rotating shaft. Several mounting rods, each capable of rotation and with their lower ends located inside the vibrating component, are vertically arranged on the turntable. A transmission structure 1 is provided between the output shaft of drive motor 1 and the rotating shaft. A transmission component is fixed along the axial direction of the rotating shaft. A transmission structure 2 is provided between the output shaft of drive motor 2 and the transmission component. The aforementioned vibratory polishing machine has certain shortcomings in use. Vibratory polishing machines mainly utilize the vibration of abrasives to polish the surface of deep drawing dies. After a period of use, some abrasives will wear down, reducing the polishing effect on deep drawing dies. Generally, small abrasive particles after wear are removed by screening. However, traditional vibratory polishing machines do not have an abrasive processing function. They can only maintain good processing results by completely replacing the abrasives, which increases their operating costs. They cannot flexibly adapt to screening abrasives of different sizes and structures, and their function is limited. Secondly, simply using a vibrator to drive the abrasive to vibrate limits the movement range of the abrasives, reducing the processing efficiency of deep drawing dies. Summary of the Invention

[0004] This invention provides a finishing and polishing device for deep drawing die parts. It addresses the problem that existing vibratory polishing machines primarily utilize abrasive vibration to polish the surface of deep drawing dies. However, after a period of use, some abrasive particles wear down, reducing the polishing effect. While sieving is typically used to remove worn small abrasive particles, traditional vibratory polishing machines lack abrasive processing capabilities and rely solely on replacing the abrasive to maintain good results, increasing operating costs. A finishing and polishing device for deep drawing die parts includes a polishing barrel, a fixed base, and a screening device. The polishing barrel is movably installed on the inner side of the upper end of the fixed base. The screening device is elastically installed on the upper end of the fixed base below the polishing barrel. The screening device includes an upper plate and a lower plate. The upper plate is slidably installed on the inner side of the upper end of the lower plate. An adjusting plate is fixedly installed on the inner side of the lower plate, below the upper plate. The polishing barrel includes an outer barrel and an inner barrel. The inner barrel is elastically installed on the inner side of the outer barrel. Several sets of arc-shaped convex rings are fixedly installed on the inner surface of the inner barrel.

[0005] As a further technical solution of the present invention, both outer surfaces of the upper plate are fixedly installed with connecting slide bars, and both inner surfaces of the lower plate are provided with slide grooves for use with connecting slide bars. By using the connecting slide bar connecting slide groove structure, the upper plate can slide inside the lower plate to adjust the position between the upper plate and the adjusting plate, thereby cooperating with the strip groove to complete the size adjustment of the screening trough.

[0006] As a further technical solution of the present invention, one end of the upper plate and the other end of the lower plate are both open structures, and the other end of the upper plate and one end of the lower plate are both sealed structures. The discharge directions of the upper plate and the lower plate are reversed. This allows the qualified abrasive material retained in the upper plate to be discharged outward from one end of the screen after the abrasive material has been vibrated and screened by the screener, while the unqualified abrasive material that has passed through the upper plate is discharged outward from the other end of the screener. This staggered discharge of the two types of abrasive material prevents them from mixing.

[0007] As a further technical solution of the present invention, the outer surface of the upper plate is provided with several sets of screening grooves, and the outer surface of the adjusting plate is provided with several sets of strip-shaped slots. When the upper plate moves within the lower plate, the strip-shaped slots and the screening grooves move vertically out of alignment. The strip-shaped slots adopt a strip-shaped structure design. When the upper plate moves, the adjusting plate blocks part of the structure of the screening grooves. One strip-shaped slot can simultaneously meet the size adjustment of several screening grooves. By setting several sets of strip-shaped slots, the size of the screening grooves on the upper plate is adjusted synchronously, so that the upper plate can meet the screening operation of abrasives of different sizes during use.

[0008] As a further technical solution of the present invention, several sets of screening troughs are arranged side by side. A fastening bolt for use with the lower plate is movably installed on one side of the upper plate. A slot for use with the fastening bolt is opened through one side of the outer surface of the lower plate. During operation, the lower plate and the upper plate can be locked and fixed by rotating the fastening bolt. In addition, the two adjacent rows of screening troughs are staggered, so that when the abrasive slides on the surface of the upper plate, it will be completely captured by the screening trough, avoiding the phenomenon of screening material leakage.

[0009] As a further technical solution of the present invention, two sets of elastic brackets are fixedly installed on both outer surfaces of the lower plate body. A spring is provided at the bottom of the elastic bracket. The lower plate body and the fixed base are elastically connected through the elastic bracket and the spring. When the screener performs vibratory screening operation, the elastic bracket and the spring can play a buffering and shock-absorbing role between the screener and the fixed base.

[0010] As a further technical solution of the present invention, the upper outer surface of the adjusting disc is provided with several sets of roller brushes. One set of roller brushes is located on one side of a set of strip grooves. The strip grooves and roller brushes are arranged side by side. During operation, the user continuously moves the upper disc to make the roller brushes contact the screening grooves. The roller brushes can be used to push the abrasive stuck in the screening grooves upwards, thus completing the cleaning operation of the screening grooves. Each strip groove corresponds to a row of screening grooves. There is a certain distance of blank area between the two rows of screening grooves. When the roller brushes are stored, they are located below the blank area between the two rows of screening grooves, so as not to affect the normal use of the screening grooves.

[0011] As a further technical solution of the present invention, a docking base for use with an elastic rod is fixedly installed on the lower outer surface of the outer barrel. Vibrators are fixedly installed on both the docking base and the lower outer surface of the lower plate. The vibrator includes a vibration motor and two sets of eccentric blocks. The two sets of eccentric blocks are respectively movably installed at both ends of the vibration motor. During operation, the abrasive and deep drawing die are placed inside the inner barrel. The vibrator is started, causing the vibration motor to drive the eccentric blocks to rotate. The centrifugal force generated by the rotation of the eccentric blocks drives the inner barrel connected by the elastic rod to perform forced vibration, thereby causing the mixture in the inner barrel to produce a specific three-dimensional spiral flow. The surface of the deep drawing die is processed through continuous and gentle friction. Secondly, the vibrator can make the screen vibrate, which facilitates the screen to vibrate and screen the material.

[0012] As a further technical solution of the present invention, one side of the outer surface of the arc-shaped convex ring is an arc-shaped structure, and several sets of arc-shaped convex rings are arranged side by side. By using the arrangement of the arc-shaped convex rings, when the vibrator drives the abrasive to vibrate, an inward force can be applied to the abrasive. Compared with the arrangement of the inner barrel of the vertical structure, when the abrasive comes into contact with the arc-shaped convex ring during vibration, the arc-shaped structure on the side of the arc-shaped convex ring allows the abrasive to be squeezed laterally when it moves up and down, so that the abrasive can complete the lateral movement synchronously, thereby realizing the three-dimensional spiral flow of the abrasive and improving the surface treatment effect of the deep drawing die.

[0013] As a further technical solution of the present invention, the outer barrel and the fixed base are movably connected by a rotating rod, and the outer barrel and the inner barrel are elastically connected by an elastic rod. A control cabinet is provided on one side of the fixed base. During operation, the rotating rod is driven by a motor, which causes the polishing barrel to rotate as a whole, thus completing the pouring of the abrasive. Furthermore, the control cabinet can control the electrical structure of the vibrator and motor of the entire device.

[0014] The beneficial effects of the present invention are as follows: By setting up a screening device, the present invention enables the deep drawing die part finishing and polishing device to have an abrasive treatment function when used, and at the same time, it can flexibly adapt to abrasive structures of different sizes, so that the polishing device can always maintain a good processing effect on the deep drawing die parts. By setting an arc-shaped convex ring, the polishing device for the precision machining of deep drawing die parts is used to optimize the effect of the polishing barrel, increase the vibration amplitude of the abrasive in the polishing barrel, and shorten the polishing time of the deep drawing die parts.

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1-4As shown, a finishing and polishing device for deep drawing die parts includes a polishing barrel 1, a fixed base 2, and a screener 3. The polishing barrel 1 is movably installed on the inner side of the upper end of the fixed base 2. The screener 3 is elastically installed on the upper end of the fixed base 2, located below the polishing barrel 1. The screener 3 includes an upper plate 4 and a lower plate 5. The upper plate 4 is slidably installed on the inner side of the upper end of the lower plate 5. An adjusting plate 9 is fixedly installed on the inner side of the lower plate 5, located below the upper plate 4. The polishing barrel 1 includes an outer barrel 16 and an inner barrel 17. The inner barrel 17 is elastically installed on the inner side of the outer barrel 16. Several sets of arc-shaped protruding rings 18 are fixedly installed on the inner surface of the inner barrel 17.

[0020] Both outer surfaces of the upper plate 4 are fixedly equipped with docking slide bars 12, and both inner surfaces of the lower plate 5 are provided with slide grooves for use with docking slide bars 12. By using the docking slide bar 12 docking slide groove structure, the upper plate 4 can slide inside the lower plate 5 to adjust the position between the upper plate 4 and the adjusting plate 9, thereby cooperating with the strip groove 14 to complete the size adjustment of the screening trough 8.

[0021] One end of the upper disc 4 and the other end of the lower disc 5 are open structures, while the other end of the upper disc 4 and one end of the lower disc 5 are sealed structures. The discharge directions of the upper disc 4 and the lower disc 5 are reversed. This allows the qualified abrasive material retained in the upper disc 4 to be discharged from one end of the screen 3 after the abrasive material is vibrated and screened by the screen 3, while the unqualified abrasive material that passes through the upper disc 4 is discharged from the other end of the screen 3. This staggered discharge of the two types of abrasive material prevents them from mixing.

[0022] Several sets of screening grooves 8 are provided through the outer surface of the upper disc 4, and several sets of strip-shaped slots 14 are provided through the outer surface of the adjusting disc 9. When the upper disc 4 moves within the lower disc 5, the strip-shaped slots 14 and the screening grooves 8 move vertically out of alignment. The strip-shaped slots 14 adopt a strip-shaped structure design. When the upper disc 4 moves, the adjusting disc 9 blocks part of the structure of the screening grooves 8. One strip-shaped slot 14 can simultaneously meet the size adjustment of several screening grooves 8. By setting several sets of strip-shaped slots 14, the size of the screening grooves 8 on the upper disc 4 can be adjusted synchronously, so that the upper disc 4 can meet the screening operation of abrasives of different sizes when in use.

[0023] Several sets of screening troughs 8 are arranged side by side. A fastening bolt 13 is movably installed on one side of the upper plate 4 to cooperate with the lower plate 5. A slot for cooperating with the fastening bolt 13 is opened through one side of the outer surface of the lower plate 5. During operation, the lower plate 5 and the upper plate 4 can be locked and fixed by rotating the fastening bolt 13. In addition, the two adjacent rows of screening troughs 8 are staggered, so that when the abrasive slides on the surface of the upper plate 4, it will be completely captured by the screening trough 8, avoiding the phenomenon of screening material leakage.

[0024] Two sets of elastic brackets 10 are fixedly installed on both outer surfaces of the lower plate 5. A spring 11 is provided at the bottom of the elastic bracket 10. The lower plate 5 and the fixed base 2 are elastically connected through the elastic brackets 10 and the spring 11. When the screener 3 performs vibrating screening operation, the elastic brackets 10 and the spring 11 can play a buffering and shock-absorbing role between the screener 3 and the fixed base 2.

[0025] Several sets of roller brushes 15 are provided on the upper outer surface of the adjusting plate 9. One set of roller brushes 15 is located on one side of a set of strip grooves 14. The strip grooves 14 and the roller brushes 15 are arranged side by side. During operation, the user continuously moves the upper plate 4 so that the roller brushes 15 come into contact with the screening trough 8. The roller brushes 15 can be used to push the abrasive stuck in the screening trough 8 upward, thus completing the cleaning operation of the screening trough 8. Each strip groove 14 corresponds to a row of screening troughs 8. There is a certain distance of blank area between the two rows of screening troughs 8. When the roller brushes 15 are stored, they are located below the blank area between the two rows of screening troughs 8, so as not to affect the normal use of the screening troughs 8.

[0026] A docking base 19 for use with the elastic rod 21 is fixedly installed on the lower outer surface of the outer barrel 16. A vibrator 20 is fixedly installed on both the docking base 19 and the lower outer surface of the lower plate 5. The vibrator 20 includes a vibrating motor and two sets of eccentric blocks. The two sets of eccentric blocks are movably installed at both ends of the vibrating motor. During operation, the abrasive and deep drawing die are placed inside the inner barrel 17. The vibrator 20 is started, which causes the vibrating motor to drive the eccentric blocks to rotate. The centrifugal force generated by the rotation of the eccentric blocks drives the inner barrel 17 connected by the elastic rod 21 to undergo forced vibration, thereby causing the mixed material inside the inner barrel 17 to generate a specific three-dimensional spiral flow. The surface of the deep drawing die is processed through continuous and gentle friction. Secondly, the vibrator 20 can be used to make the screen 3 vibrate, which facilitates the screen 3 to vibrate and screen the material.

[0027] One outer surface of the arc-shaped convex ring 18 has an arc-shaped structure. Several sets of arc-shaped convex rings 18 are arranged side by side, one above the other. By using the arc-shaped convex rings 18, when the vibrator 20 drives the abrasive to vibrate, an inward force can be applied to the abrasive. Compared with the vertical structure of the inner barrel 17, when the abrasive comes into contact with the arc-shaped convex ring 18 during vibration, the arc-shaped structure on the side of the arc-shaped convex ring 18 allows the abrasive to be squeezed laterally when it moves up and down, so that the abrasive can complete the lateral movement synchronously, thereby realizing the three-dimensional spiral flow of the abrasive and improving the surface treatment effect of the deep drawing die.

[0028] The outer barrel 16 and the fixed base 2 are movably connected by a rotating rod 7, and the outer barrel 16 and the inner barrel 17 are elastically connected by an elastic rod 21. A control cabinet 6 is provided on one side of the fixed base 2. During operation, the rotating rod 7 is driven by a motor, which causes the polishing barrel 1 to rotate as a whole, thus completing the pouring of abrasive. Furthermore, the control cabinet 6 can control the electrical structure of the vibrator 20 and the motor of the entire device.

[0029] A precision polishing device for deep drawing mold parts is provided. The abrasive and the deep drawing mold are placed inside an inner barrel 17. A vibrator 20 is activated, causing a vibration motor to drive an eccentric block to rotate. The centrifugal force generated by the rotating eccentric block drives the inner barrel 17, connected by an elastic rod 21, to undergo forced vibration. This causes a specific three-dimensional spiral flow in the mixture within the inner barrel 17. The surface of the deep drawing mold is processed through continuous and gentle friction. The arc-shaped convex ring 18 applies an inward force to the abrasive when the vibrator 20 drives it to vibrate. Compared to a vertical inner barrel 17, when the abrasive contacts the arc-shaped convex ring 18 during vibration, the arc-shaped structure on the side of the ring allows the abrasive to be laterally compressed as it moves up and down, thus achieving a three-dimensional spiral flow of the abrasive and improving the surface treatment effect of the deep drawing mold. The vibrator 20 drives the entire screen 3 to vibrate. Using the connecting slide bar 12 and the connecting groove structure, the upper plate 4 can slide inside the lower plate 5, adjusting the position between the upper plate 4 and the adjusting plate 9. The strip groove 14 adopts a strip structure design. When the upper plate 4 moves, the adjusting plate 9 partially blocks the structure of the screening trough 8. One strip groove 14 can simultaneously accommodate the size adjustment of several screening troughs 8. By setting several sets of strip grooves 14, the size of the screening troughs 8 on the upper plate 4 can be adjusted synchronously, allowing the upper plate 4 to meet the screening operation of abrasives of different sizes during use. The lower plate 5 and the upper plate 4 can be locked and fixed by rotating the fastening bolt 13. Secondly, the two adjacent rows of screening grooves 8 are staggered, so that when the abrasive slides on the surface of the upper plate 4, it will be completely captured by the screening groove 8, avoiding the phenomenon of screening material leakage. The discharge directions of the upper plate 4 and the lower plate 5 are opposite, so that after the abrasive is vibrated and screened by the screening device 3, the qualified abrasive that is retained in the upper plate 4 is discharged outward from one end of the screening device 3, while the unqualified abrasive that passes through the upper plate 4 is discharged outward from the other end of the screening device 3, so that the two types of abrasive are staggered and discharged to avoid mixing.

[0030] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
