Description

Technical Field

[0001] This utility model belongs to the field of metal deburring technology, and relates to a novel metal deburring device. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces of the desired shape and size. Stamping and forging are both plastic processing methods, collectively known as forging and pressing. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. Stamped parts usually require deburring during processing. For punched holes in metal stampings, burrs often remain on the edges of the holes after stamping. If these burrs are not removed, they can easily affect subsequent assembly or scratch the surface of other components. Current methods for deburring punched holes generally involve manually sanding the edges with sandpaper. This method is inefficient, time-consuming, and labor-intensive. Furthermore, some existing deburring devices cannot be flexibly adjusted according to the hole diameter, resulting in poor flexibility and adaptability.

[0003] Therefore, this utility model provides a novel deburring device for metal parts, which solves the above problems. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses a novel deburring device for metal parts. The technical solution adopted is as follows: The frame includes a base, and support legs are installed at the four corners of the lower surface of the base. A deburring assembly is inserted into the central hole of the base through a bearing. The deburring assembly includes a hollow rotating shaft. Through holes are symmetrically opened in the middle of the left and right sides of the rotating shaft. A cylindrical airbag is fixedly fitted around the rotating shaft. Several sets of Velcro are fixedly arranged in a circumferential array on the outer wall of the cylindrical airbag. Sandpaper is adhered to the outside of the Velcro. The left and right sides of the inner wall of the cylindrical airbag, corresponding to the positions of the through holes, are respectively sealed and connected to the left and right ends of a T-shaped air tube. A rotary sealing joint is screwed onto the lower end of the rotating shaft. The upper end of the rotary sealing joint is sealed and connected to the lower end of the T-shaped air tube. The left end of the rotary sealing joint is sealed and connected to the inflation end of an air pump installed on the lower surface of the base through an air tube. The lower periphery of the rotating shaft is driven by a drive mechanism installed on the lower right side of the base.

[0005] In a preferred embodiment of this utility model, a shelf with a central opening is provided on the upper part of the base. Movable columns are fixedly connected to the four edges of the lower surface of the shelf. The lower end of the movable column movably passes through the base, and a spring is also fitted on the movable column. By using a shelf that can move vertically back and forth, the stamped part that needs to be deburred by grinding can be placed on the upper part, so that its punch is fitted onto the deburring assembly. When grinding, the shelf is pressed down, and under the action of elasticity and continuous pressure, the stamped part is driven to move up and down back and forth, thereby avoiding excessive wear caused by repeated grinding of the same position by sandpaper, reducing the consumption of sandpaper, and improving the grinding effect.

[0006] As a preferred embodiment of this utility model, the central opening of the shelf is larger than the outer diameter of the cylindrical airbag when it is at its maximum deformation; this design can avoid friction between the sandpaper and the circular airbag and the shelf when grinding stamped parts with large punch holes.

[0007] In a preferred embodiment of this utility model, the driving mechanism includes a first synchronous pulley fixedly mounted on the lower end of the rotating shaft, a synchronous belt mounted on the first synchronous pulley, the right end of the synchronous belt mounted on a second synchronous pulley, the second synchronous pulley fixedly mounted on the output shaft of a motor, and the motor fixedly mounted on the lower part of the base by an external U-shaped bracket; by using a driving mechanism, the rotating shaft and the circular airbag are driven to rotate, thereby achieving rotary grinding of the through holes of the stamped parts mounted on their periphery, improving the grinding effect.

[0008] As a preferred embodiment of this utility model, a control panel is installed on the front right corner of the upper surface of the base.

[0009] As a preferred embodiment of this utility model, a controller is installed on the right front edge of the lower surface of the base.

[0010] The beneficial effects of this utility model are as follows: By using an air pump to control the inflation and deflation of the airbag, the sandpaper attached to the surface of the cylindrical airbag by Velcro is spread out or gathered together, thereby flexibly adapting to the needs of deburring the punched edges of stamped parts with different hole diameters within a certain range, thus improving the flexibility and adaptability of the device; at the same time, the drive mechanism drives the deburring component to rotate at high speed, and in conjunction with the placement plate that can be pressed to make it move up and down, the punched holes of metal stamped parts can be quickly polished, thereby improving the deburring efficiency.

Detailed Implementation

[0016] Example 1

[0017] like Figures 1 to 4As shown, the novel deburring device for metal parts of this utility model adopts the following technical solution: It includes a frame 1, which includes a base 11. Support legs 12 are installed at the four corners of the lower surface of the base 11. A placement plate 13 with a central opening is provided on the upper part of the base 11. The central opening of the placement plate 13 is larger than the outer diameter of the cylindrical airbag 22 when it is at its maximum deformation. Moving columns 14 are fixedly connected to the four edges of the lower surface of the placement plate 13. The lower end of the moving column 14... The movable column 14 is fitted with a spring 15 and a deburring assembly 2 is inserted into the central hole of the base 11 via a bearing. The deburring assembly 2 includes a hollow rotating shaft 21 with symmetrical through holes 211 on the middle of its left and right sides. A cylindrical airbag 22 is fixedly fitted around the rotating shaft 21. Several sets of Velcro 23 are fixedly arranged in a circular array on the outer wall of the cylindrical airbag 22. Sandpaper 24 is adhered to the outside of the Velcro 23. The left and right sides of the inner wall of the shaft 22 are respectively sealed and connected to the left and right ends of the T-shaped air tube 25 at the positions corresponding to the through holes 211. The lower end of the shaft 21 is sealed and screwed with a rotary sealing joint 26. The upper end of the rotary sealing joint 26 is sealed and connected to the lower end of the T-shaped air tube 25. The left end of the rotary sealing joint 26 is sealed and connected to the inflation end of the air pump 27 installed on the lower surface of the base through an air tube. The lower periphery of the shaft 21 is driven by a drive mechanism 3 installed on the lower right side of the base. The drive mechanism 3 includes a first synchronous pulley 31 fixedly mounted on the lower end of the shaft 21. A synchronous belt 32 is mounted on the first synchronous pulley 31. The right end of the synchronous belt 32 is mounted on a second synchronous pulley 33. The second synchronous pulley 33 is fixedly mounted on the output shaft of the motor 34. The motor 34 is fixedly mounted on the lower part of the base through an external U-shaped bracket 35. A control panel 4 is installed on the upper front right corner of the base 11. A controller 5 is installed on the lower front right edge of the base 11.

[0018] The working principle of this utility model is as follows: In use, the punched hole of the stamped part to be deburred is aligned with the cylindrical airbag 22 of the deburring assembly 2 and placed on the shelf 13. The air pump 27 is controlled by the control panel 4 to slowly inflate the cylindrical airbag 22, causing it to gradually expand. This allows the sandpaper 24 arranged in a circular pattern around the airbag to press and contact the edge of the punched hole. Inflation is then stopped, and the motor 34 is turned on. The motor 34, through the mechanical transmission of the second synchronous pulley 33, the synchronous belt 32, and the first synchronous pulley 31, drives... The rotating shaft 21 and the cylindrical airbag 22 rotate, and the rotating sandpaper 24 rubs the burrs on the edge of the punch. Then, the stamping part is pressed tightly onto the shelf 13 by both hands and the shelf 13 is moved downward. After the pressure reaches the moving position, the shelf 13 and the stamping part are automatically lifted under the action of the spring 15. This continuous pressure and automatic lifting cause the stamping plate to move up and down along the cylindrical airbag 22, thereby allowing the sandpaper 24 in the circumferential array of the cylindrical airbag 22 to quickly remove the burrs on the edge of the punch.
