[0027] The utility model provides a bending device: including a processing table 101, a mounting arm 102, a servo motor 103, a bracket 104, a bending assembly 105 and a feeding mechanism, wherein the feeding mechanism includes a supporting arm 106, a mounting seat 107, a rotating assembly 108, a rotating disk 109, a fixed plate 110, a rotating shaft 111, a driving assembly 112, a threaded column 113 and a pushing head 114, wherein the rotating assembly 108 includes a first driving motor 115 and an output gear 116, and the driving assembly 112 includes a second driving motor 117 and a driving gear 118. The above-mentioned scheme solves the problem that the existing metal sheet bending mechanism is not provided with an automatic feeding mechanism, the automatic feeding of the metal sheet cannot be completed, the staff needs to manually complete the feeding of the metal sheet, and the operation is not convenient. It can be understood that the above-mentioned scheme can be used in the structure of the metal sheet bending device.

[0028] According to this specific embodiment, the upper surface of the processing table 101 is provided with the bracket 104, and the bending assembly 105 is installed on the bracket 104. The upper surface of the processing table 101 is also provided with the mounting arm 102, and the mounting arm 102 is located on one side of the bracket 104. The top of the mounting arm 102 is installed with the servo motor 103, and the output end of the servo motor 103 is provided with a positive and negative threaded rod 119, and both ends of the positive and negative threaded rod 119 are provided with a ball 127 screw nut pair 120, and each of the ball 127 screw nut pair 120 is fixedly installed with a clamping plate 121, which is used to be bent. After the metal sheet is placed between the two clamping plates 121, the servo motor 103 is started to drive the positive and negative threaded rod 119 to rotate, and the two clamping plates 121 are driven to move toward each other through the ball 127, the screw nut pair 120, so that the metal sheet is firmly clamped by the two clamping plates 121, and then the metal sheet is bent by the bending component 105. Through the arrangement of the servo motor 103 and the positive and negative threaded rod 119, the two clamping plates 121 can clamp and fix metal sheets of different widths, and the applicability is strong. The bending component 105 is a prior art, so it is not described in detail.

[0029] Among them, the support arm 106 is installed on the upper surface of the processing table 101 and is located on the side of the mounting arm 102 away from the bracket 104. The top of the support arm 106 is provided with the mounting seat 107, and the rotating disk 109 is rotatably provided on the mounting seat 107. The rotating component 108 is arranged inside the mounting seat 107. The output end of the rotating component 108 is mechanically transmitted with the rotating disk 109. The rotating disk 109 is far away from the mounting seat 107. The fixed plate 110 is provided with the rotating shaft 111 rotatably provided on the fixed plate 110. The internal thread of the rotating shaft 111 is connected with the threaded column 113, and the pushing head 114 is arranged on the end of the threaded column 113 close to the mounting arm 102. The driving component 112 is also provided on the fixed plate 110, and the transmission gear 122 is arranged on the outside of the rotating shaft 111. The output end of the driving component 112 is mechanically transmitted with the transmission gear 122. The movable gear 122 is mechanically transmitted. After the metal sheet to be bent is placed between the two clamping plates 121, the rotating assembly 108 is started to drive the rotating disk 109 to rotate on the mounting seat 107, so that the fixed plate 110 is rotated to the end of the metal sheet away from the output end of the bending assembly 105. At this time, the pushing head 114 corresponds to the end of the metal sheet, and the driving assembly 112 is started. The rotating shaft 111 is driven to rotate on the fixed plate 110 through the transmission gear 122. Since the internal thread of the rotating shaft 111 is connected with the threaded column 113, the threaded column 113 is screwed into the inside of the rotating shaft 111, and then the end of the metal sheet is forced through the pushing head 114, so that the part of the metal sheet to be bent is located at the output end of the bending assembly 105, and the feeding of the metal sheet is completed. With the above structure, the degree of automation is higher and the operation is more convenient when feeding the metal sheet.

[0030] Secondly, a driven tooth portion 123 is provided on one side of the rotating disk 109 located inside the mounting seat 107, and the first driving motor 115 is installed inside the mounting seat 107. The output end of the first driving motor 115 is provided with the output gear 116, and the output gear 116 is meshed with the driven tooth portion 123. The first driving motor 115 is started to drive the output gear 116 to rotate. Since the output gear 116 is meshed with the driven tooth portion 123, the rotating disk 109 is driven to rotate on the mounting seat 107. A heat dissipation groove 124 is penetrated on the outer side wall of the mounting seat 107, and the heat dissipation groove 124 corresponds to the first driving motor 115. Through the setting of the heat dissipation groove 124, the interior of the mounting seat 107 is kept in circulation with the outside air, so that the heat generated by the first driving motor 115 when working is taken away by the flowing air.

[0031] At the same time, the second drive motor 117 is installed on the fixed plate 110, and the drive gear 118 is provided at the output end of the second drive motor 117. The drive gear 118 is meshed with the transmission gear 122. When the second drive motor 117 is started, the drive gear 118 is driven to rotate. Since the drive gear 118 is meshed with the transmission gear 122, the rotating shaft 111 is driven to rotate on the fixed plate 110.

[0032] In addition, two limit rings 125 are provided on the outside of the rotating shaft 111, and the two limit rings 125 are respectively located on the two sides of the fixed plate 110. Through the setting of the limit rings 125, the structure is more stable when the rotating shaft 111 rotates. Each limit ring 125 is provided with an annular groove 126 on one side close to the fixed plate 110, and a plurality of balls 127 are provided inside the annular groove 126. Through the setting of the annular groove 126 and the balls 127, the rotating shaft 111 rotates more smoothly.

[0033] When using a bending device of the present embodiment, after placing the metal sheet to be bent between the two clamping plates 121, start the servo motor 103 to drive the positive and negative threaded rod 119 to rotate, and drive the two clamping plates 121 to move toward each other through the ball 127 screw nut pair 120, so that after the metal sheet is firmly clamped by the two clamping plates 121, the metal sheet is bent by the bending component 105. Through the arrangement of the servo motor 103 and the positive and negative threaded rod 119, the two clamping plates 121 can clamp and fix metal sheets of different widths, which has strong applicability. After placing the metal sheet to be bent between the two clamping plates 121, start the rotating component 108 to drive the rotating disk 109 to move. The mounting base 107 is rotated so that the fixed plate 110 is rotated to the end of the metal sheet away from the output end of the bending component 105. At this time, the pushing head 114 corresponds to the end of the metal sheet, and the driving component 112 is started. The rotating shaft 111 is driven to rotate on the fixed plate 110 through the transmission gear 122. Since the internal thread of the rotating shaft 111 is connected with the threaded column 113, the threaded column 113 is screwed into the inside of the rotating shaft 111, and then the pushing head 114 applies force to the end of the metal sheet, so that the part of the metal sheet to be bent is located at the output end of the bending component 105, and the feeding of the metal sheet is completed. With the above structure, the degree of automation is higher and the operation is more convenient when feeding the metal sheet.

[0037] According to this specific embodiment, the protective shell 201 is also provided on the fixing plate 110, and the protective shell 201 is provided on the outside of the driving component 112 and the transmission gear 122. The driving component 112 and the transmission gear 122 are protected by the protective shell 201 to prevent the external environment from affecting the meshing point of the driving gear 118 and the transmission gear 122.

[0038] Among them, mounting blocks 202 are provided on both sides of one end of the protective shell 201 close to the fixed plate 110, and the mounting blocks 202 are detachably connected to the fixed plate 110. After the protective shell 201 is placed outside the driving assembly 112 and the transmission gear 122, the mounting blocks 202 are fixed to the fixed plate 110 with screws, thereby completing the installation of the protective shell 201.

[0039] When using a bending device of this embodiment, after placing the protective shell 201 on the outside of the driving component 112 and the transmission gear 122, the mounting block 202 is fixed to the fixing plate 110 with screws, thereby completing the installation of the protective shell 201.
