[0022] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 2 As shown, it is a structural diagram of an air-conditioning fan blade stamping device provided by an embodiment of the present invention, comprising a workbench 1, a column 2 is rotatably mounted on the surface of the workbench 1, a fixed plate 3 is fixedly mounted on the top of the column 2, a fixed frame 4 located outside the fixed plate 3 is fixedly mounted on the surface of the workbench 1, a hydraulic cylinder 5 is fixedly mounted on the top wall of the fixed frame 4, a horizontal plate 6 is fixedly mounted on the output shaft of the hydraulic cylinder 5, a punching block 7 is fixedly mounted on the bottom wall of the horizontal plate 6, a second positioning mechanism 9 is arranged on the surface of the workbench 1, the second positioning mechanism 9 comprises a supporting assembly 91 and a driving assembly 92, the supporting assembly 91 is located on the surface of the workbench 1 and is in contact with the bottom wall of the fixed plate 3, and the supporting assembly 91 is used to improve the fixing The stability of the disk 3, the driving component 92 is located on the surface of the workbench 1 and is connected to the column 2. When the cross plate 6 moves from bottom to top along the vertical direction, the driving component 92 is used to control the column 2 to intermittently rotate a certain angle. The surface of the fixed disk 3 is provided with a first positioning mechanism 8 that cooperates with the parts to be stamped. The first positioning mechanism 8 includes a bearing component 81 and a unloading component 82. The bearing component 81 is located on the surface of the fixed disk 3. The bearing component 81 is used to position the parts to be stamped on the surface of the fixed disk 3. The unloading component 82 is connected to the bearing component 81. When the column 2 drives the fixed disk 3 to rotate intermittently, the unloading component 82 removes the stamped parts from the surface of the fixed disk 3 by cooperating with the bearing component 81.

[0024] When in use, multiple groups of parts to be stamped are placed on the surface of the fixed disk 3, the bearing assembly 81 positions the parts to be stamped, the hydraulic cylinder 5 pushes the cross plate 6 to move vertically downward, and the cross plate 6 drives the stamping block 7 to move downward synchronously, and the stamping block 7 can quickly stamp the parts to be stamped directly below the surface of the fixed disk 3. After the stamping is completed, the hydraulic cylinder 5 pulls the cross plate 6 and the stamping block 7 to move vertically upward. When the cross plate 6 and the stamping block 7 move vertically upward, the driving assembly 92 controls the column 2 to rotate a certain angle on the surface of the workbench 1, and the column 2 drives the fixed disk 3 to rotate synchronously at a certain angle. The fixed disk 3 drives multiple groups of parts to be stamped on its surface to rotate synchronously, so that another group of parts to be stamped rotates to directly below the stamping block 7. When the fixed disk 3 rotates, the unloading assembly 82 cooperates with the bearing assembly 81 to automatically remove the stamped parts from the surface of the fixed disk 3, effectively saving manpower and time.

[0025] like Figure 1 , Figure 2 , Figure 3As shown, as a preferred embodiment of the present invention, the support assembly 91 includes a plurality of groups of vertical rods 911 fixedly installed on the surface of the workbench 1, and a support ring 912 located below the fixed plate 3 is commonly fixedly installed on the top of the plurality of groups of vertical rods 911, and a plurality of groups of rollers 913 distributed in a ring are rotatably installed on the surface of the support ring 912, and the rollers 913 are in contact with the bottom wall of the fixed plate 3.

[0026] When the punching block 7 moves vertically downward and punches the part to be punched, the support ring 912 cooperates with the roller 913 to support and position the fixed plate 3, effectively improving the stability of the fixed plate 3 and preventing the fixed plate 3 from tilting due to unilateral pressure.

[0027] like Figure 1 , Figure 2 , Figure 4 , Figure 6 As shown, as a preferred embodiment of the present invention, the driving assembly 92 includes a driven bevel gear plate 921 fixedly mounted on the surface of the column 2, two groups of positioning plates 922 distributed in parallel are fixedly mounted on the surface of the workbench 1, and a driving shaft 923 is installed on the two groups of positioning plates 922 for common rotation, and an active bevel gear plate 924 is fixedly mounted on one end of the driving shaft 923 facing the column 2, and the active bevel gear plate 924 is meshingly connected with the driven bevel gear plate 921, and a transmission gear plate 925 is fixedly mounted on the end of the driving shaft 923 away from the column 2, and a second rack 926 meshing with the transmission gear plate 925 is arranged below the cross plate 6, and a translation portion 11 connected to the second rack 926 is arranged on the bottom wall of the cross plate 6, and the translation portion 11 is used to adjust the relative position of the second rack 926 and the transmission gear plate 925 below the cross plate 6.

[0028] The hydraulic cylinder 5 pushes the cross plate 6 and the punching block 7 to move vertically downward for punching processing. The cross plate 6 drives the second rack 926 to move downward synchronously. When moving downward, the translation part 11 adjusts the position of the second rack 926, and the second rack 926 is separated from the transmission gear disc 925. The second rack 926 will not interfere with the transmission gear disc 925. When the stamping is completed, the hydraulic cylinder 5 pulls the cross plate 6 and the stamping block 7 to move vertically upward, and the cross plate 6 drives the second rack 926 to move upward synchronously, and the translation part 11 adjusts the position of the second rack 926 again. When the second rack 926 moves upward, it meshes with the transmission gear plate 925 for transmission, and the transmission gear plate 925 can be controlled to rotate, and the transmission gear plate 925 drives the driving shaft 923 to rotate, and the driving shaft 923 drives the active bevel gear plate 924 to rotate synchronously, and the active bevel gear plate 924 is meshed with the driven bevel gear plate 921 for transmission, which can drive the column 2 to rotate synchronously on the surface of the workbench 1 by a certain angle, and the column 2 drives the fixed plate 3 to rotate synchronously by a certain angle, and then the positions of multiple groups of parts to be stamped can be adjusted synchronously, so that a group of parts to be stamped can be rotated to the bottom of the stamping block 7, which is convenient for stamping again.

[0029] like Figure 2 , Figure 6 As shown, as a preferred embodiment of the present invention, the translation portion 11 includes a slide groove 111 opened on the bottom wall of the horizontal plate 6, a sliding block 112 is slidably installed in the slide groove 111, the top of the second rack 926 is fixedly connected to the sliding block 112, an electric telescopic rod 113 is fixedly installed in the slide groove 111, and the telescopic end of the electric telescopic rod 113 is connected to the sliding block 112.

[0030] The electric telescopic rod 113 pushes the sliding block 112 to move in the slide slot 111, and the sliding block 112 drives the second rack 926 to move synchronously. When the horizontal plate 6 drives the punching block 7 to move vertically downward for punching, the second rack 926 and the transmission gear plate 925 are separated from each other. When the punching is completed, the horizontal plate 6 drives the punching block 7 to move vertically upward, and the electric telescopic rod 113 and the sliding block 112 cooperate with each other to adjust the position of the second rack 926. When the second rack 926 moves upward, it meshes with the transmission gear plate 925 for transmission, and can drive the transmission gear plate 925 to rotate.

[0031] like Figure 1 , Figure 2 , Figure 5 As shown, as a preferred embodiment of the present invention, the bearing assembly 81 includes a plurality of groups of annularly distributed fixing grooves 811 opened on the surface of the fixing plate 3, a bearing column 812 is rotatably installed in the fixing groove 811, a bearing block 813 located in the fixing groove 811 is fixedly installed on the surface of the bearing column 812, and a stamping groove 814 that cooperates with the stamping block 7 is opened on the surface of the bearing block 813.

[0032] The supporting column 812 supports and positions the supporting block 813 in the fixed groove 811, and places the workpiece to be stamped in the stamping groove 814. The fixed disk 3 rotates and drives the supporting block 813 to rotate synchronously. When a group of supporting blocks 813 moves to directly below the stamping block 7, the stamping block 7 moves vertically downward and can quickly stamp the workpiece to be stamped in the stamping groove 814. After a single stamping process is completed, the fixed disk 3 rotates a certain angle again, and the unloading assembly 82 controls the supporting column 812 to rotate 360 ​​degrees. The supporting column 812 drives the supporting block 813 to rotate 360 ​​degrees synchronously in the fixed groove 811. When the stamping groove 814 on the surface of the supporting block 813 rotates to an opening downward state, the stamped workpiece in the stamping groove 814 can automatically fall from the surface of the fixed disk 3.

[0033] like Figure 1 , Figure 3 , Figure 5As shown, as a preferred embodiment of the present invention, the unloading assembly 82 includes a fixed toothed disk 821, one end of which extends from a supporting column 812 to the outside of the fixed disk 3 and is fixedly installed. A plurality of groups of support rods 822 are fixedly installed on the surface of the workbench 1. An arc-shaped first rack 823 is commonly fixedly installed on the top of the plurality of groups of support rods 822. The first rack 823 is meshed with the fixed toothed disk 821. A limiting portion 10 that cooperates with the supporting block 813 is provided in the fixed groove 811. The limiting portion 10 is used to control the supporting block 813 to maintain a horizontal state.

[0034] The limiting portion 10 positions the supporting block 813 in the fixed groove 811, and the supporting block 813 maintains a horizontal state. After a single stamping is completed, the fixed disk 3 drives the supporting block 813 and the fixed toothed disk 821 to rotate synchronously. The fixed toothed disk 821 rolls along the surface of the first rack 823, and the fixed toothed disk 821 drives the supporting column 812 to rotate 360 ​​degrees synchronously. After the supporting column 812 and the supporting block 813 rotate 360 ​​degrees, the fixed toothed disk 821 and the first rack 823 are separated from each other, and the limiting portion 10 controls the supporting block 813 in the fixed groove 811 to maintain a horizontal state again.

[0035] like Figure 5 As shown, as a preferred embodiment of the present invention, the limiting portion 10 includes a first magnetic sheet 101 fixedly installed on the side wall of the fixing groove 811, and the side wall of the supporting block 813 is fixedly installed with a second magnetic sheet 102 that cooperates with the first magnetic sheet 101.

[0036] Initially, the first magnetic sheet 101 and the second magnetic sheet 102 are attached to each other and connected to form a whole through magnetic attraction, and the bearing block 813 is stably kept in a horizontal state in the fixed groove 811. The fixed toothed disc 821 rolls along the surface of the first rack 823, and the fixed toothed disc 821 drives the bearing column 812 and the bearing block 813 to rotate 360 ​​degrees synchronously. When the bearing block 813 rotates, the first magnetic sheet 101 and the second magnetic sheet 102 are separated from each other. After the bearing block 813 rotates 360 degrees, the first magnetic sheet 101 and the second magnetic sheet 102 are attached to form a whole again.

[0037] The working principle of the present invention is as follows: the bearing column 812 supports and positions the bearing block 813 in the fixed groove 811, the workpiece to be stamped is placed in the stamping groove 814, the hydraulic cylinder 5 pushes the cross plate 6 to move vertically downward, the cross plate 6 drives the stamping block 7 to move downward synchronously, and when the cross plate 6 drives the stamping block 7 to move vertically downward for stamping processing, the second rack 926 and the transmission gear plate 925 are separated from each other. The stamping block 7 can quickly stamp the workpiece to be stamped directly below the surface of the fixed plate 3. After the stamping is completed, the hydraulic cylinder 5 pulls the cross plate 6 and the stamping block 7 to move vertically upward. When the cross plate 6 and the stamping block 7 move vertically upward, the electric telescopic rod 113 and the sliding block 112 cooperate with each other to adjust the position of the second rack 926. When the second rack 926 moves upward, it meshes with the transmission gear plate 925 for transmission, and can drive the transmission gear plate 925 to rotate. The transmission gear plate 925 drives the driving shaft 923 to rotate, and the driving shaft 923 drives the active bevel gear plate 924 to rotate synchronously. The active bevel gear plate 924 and the driven bevel gear plate 921 are meshed and transmitted, which can drive the column 2 to rotate synchronously at a certain angle on the surface of the workbench 1, and the column 2 drives the fixed plate 3 to rotate synchronously at a certain angle, thereby synchronously adjusting the positions of multiple groups of parts to be stamped, so that one group of parts to be stamped can be rotated to the bottom of the stamping block 7, which is convenient for stamping again.

[0038] After a single stamping is completed, the fixed disk 3 drives the bearing block 813 and the fixed toothed disk 821 to rotate synchronously, and the fixed toothed disk 821 rolls along the surface of the first rack 823, and the fixed toothed disk 821 drives the bearing column 812 to rotate 360 ​​degrees synchronously. After the bearing column 812 and the bearing block 813 rotate 360 ​​degrees, the fixed toothed disk 821 and the first rack 823 separate from each other, and the bearing block 813 is controlled to remain in a horizontal state again in the fixed groove 811. When the stamping groove 814 on the surface of the bearing block 813 rotates to the state of opening downward, the stamped parts in the stamping groove 814 can automatically fall from the surface of the fixed disk 3.

[0039] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
