Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.

[0019] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0020] Please see Figure 1 The present invention provides a punching device for metal part processing, the punching device for metal part processing includes: The system comprises a base 1 and two side plates 2, with one side plate 2 fixedly mounted on the base 1 and the other two side plates 2 connected to a top plate 3 at their ends away from the base 1; a support plate 4, fixedly mounted on the base 1, with a support platform 5 fixedly mounted on the support plate 4, on which metal parts can be placed for punching, and the support platform 5 has through holes for punching waste to pass through; a clamping mechanism 6, mounted on the support plate 4 and the support platform 5, for pressing and fixing the metal parts placed on the support platform 5; and a pressing mechanism 7, mounted on the top plate 3, with a punch 8 installed at the power output end of the pressing mechanism 7 for punching the metal parts on the support platform 5, the punch 8 being detachable, and the power input end of the clamping mechanism 6 being connected to the pressing mechanism 7, the pressing mechanism 7 being used to control the clamping mechanism 6 to clamp or release the metal parts.

[0021] When using this metal part punching device, first place the metal part to be processed on the support table 5, then turn on the pressing mechanism 7. The pressing mechanism 7 will move the punch 8 directly above the position on the metal part that needs to be punched. Turn on the pressing mechanism 7 again, and the pressing mechanism 7 will move the punch 8 downward. The downward movement of the pressing mechanism 7 will drive the clamping mechanism 6 to clamp the metal part. The pressing mechanism 7 will then drive the punch 8 to punch the metal part. The waste material after punching will fall into the collection box below the support table 5 for collection. After punching is completed, the pressing mechanism 7 will move the punch 8 upward to reset, and at the same time the clamping mechanism 6 will release the metal part. Then the metal part can be taken out from the support table 5.

[0022] like Figure 2 As shown, in a preferred embodiment of the present invention, the clamping mechanism 6 includes: a first rack 61, which is fixedly connected to a pressing mechanism 7, the pressing mechanism 7 being used to drive the first rack 61 to rise or fall, the first rack 61 meshing with a first gear 62 rotatably mounted on the side plate 2, the first gear 62 being coaxially connected to a threaded rod 63 rotatably connected to the support platform 5; a guide rod 64, which is fixedly connected to the support plate 4, the guide rod 64 being sleeved with a guide block 65 threadedly connected to the threaded rod 63, the guide block 65 being fixedly connected with a buffer assembly 66, the buffer assembly 66 being fixedly connected with a pressing plate 67 slidably connected to the support platform 5, the two pressing plates 67 being used to press and fix the metal parts on the support platform 5.

[0023] like Figure 2 As shown, in a preferred embodiment of the present invention, the buffer assembly 66 includes: a connecting plate 661, which is fixedly connected to the guide block 65; a sleeve 662 is fixedly disposed on the connecting plate 661; a sleeve rod 663 is slidably disposed on the sleeve 662; a pressing plate 67 is fixedly connected to the sleeve rod 663; and a buffer spring 664, whose two ends are fixedly connected to the sleeve 662 and the pressing plate 67 respectively, for providing buffering for the metal parts on the support platform 5.

[0024] When clamping and fixing the metal part, the downward pressing mechanism 7 moves downward, which drives the first rack 61 to move downward. The downward movement of the first rack 61 drives the first gear 62 and the threaded rod 63 to rotate on the side plate 2. The rotation of the threaded rod 63 causes the guide block 65 to drive the connecting plate 661, sleeve 662, sleeve rod 663 and pressing plate 67 to move. The pressing plates 67 on both sides can press and fix the metal part. As the downward pressing mechanism 7 moves downward, after the pressing plate 67 presses the metal part, the sleeve 662 can slide along the sleeve rod 663 and compress the buffer spring 664. The buffer spring 664 can play a buffering role, ensuring that the pressing plate 67 can always press the metal part tightly during the punching process.

[0025] like Figure 1 As shown, in a preferred embodiment of the present invention, the pressing mechanism 7 includes: a hydraulic telescopic rod 71, which is fixedly installed on the top plate 3, and the power output end of the hydraulic telescopic rod 71 is slidably connected to a front and rear slide rail 72. A groove 73 is fixedly provided on the front and rear slide rail 72, and grooves are provided on both sides of the groove 73; a second rack 74, which is fixedly installed on the upper side of the groove 73, and a slide rod 75 is fixedly connected in the groove of the groove 73; a front and rear drive assembly 76, which is fixedly installed on the top plate 3, and the front and rear drive assembly 76 meshes with the second rack 74 and is slidably sleeved on the slide rod 75, for driving the groove 73 to move back and forth; and a left and right drive assembly 77, which is installed on the groove 73, and the punch 8 is installed on the left and right drive assembly 77 and is detachable, and the left and right drive assembly 77 is used to drive the punch 8 to move left and right.

[0026] Before punching, the punch 8 needs to be moved directly above the position where the metal part needs to be punched. First, the front and rear drive assembly 76 can be turned on. The front and rear drive assembly 76 can drive the second rack 74, the groove 73, the slide rod 75 and the front and rear slide rails 72 to move forward or backward on the hydraulic telescopic rod 71 to move the punch 8 to the appropriate front and rear position. Then, the left and right drive assembly 77 can be turned on. After the punch 8 is moved to the appropriate left and right position, the hydraulic telescopic rod 71 can be turned on. The hydraulic telescopic rod 71 can drive the groove 73 and the front and rear drive assembly 76 to move downward. While the front and rear drive assembly 76 moves downward, it can drive the clamping mechanism 6 to press and fix the metal part. The downward movement of the groove 73 can drive the punch 8 to move downward through the left and right drive assembly 77. The downward movement of the punch 8 can punch the metal part on the support table 5.

[0027] like Figure 3 and Figure 4As shown, in a preferred embodiment of the present invention, the front and rear drive assembly 76 includes: a suspension rod 761, which is fixedly installed on the top plate 3, a lifting block 762 is sleeved on the suspension rod 761, a first rack 61 and the lifting block 762 are fixedly connected, a slider 763 is fixedly installed on the lifting block 762, and the slider 763 is sleeved on the slide rod 75; two support plates 764, which are fixedly installed on the lifting block 762, and a shaft 765 is rotatably installed on the two support plates 764, and a first power member 766 installed on the support plate 764 is connected to the end of the shaft 765; and a second gear 767, which is fixedly installed on the shaft 765 and meshes with the second rack 74.

[0028] When the punch on the control groove 73 moves back and forth, the first power component 766 is activated. The first power component 766 is a motor. The output shaft of the first power component 766 drives the second gear 767 on the shaft 765 to rotate. The rotation of the second gear 767 causes the second rack 74, the groove 73 and the slide bar 75 to move back and forth along the slider 763. The back and forth movement of the groove 73 drives the punch to move back and forth.

[0029] like Figure 5 As shown, in a preferred embodiment of the present invention, the left and right drive assembly 77 includes: a lead screw 771, both ends of which are fixedly connected to the inner wall of the groove 73, and a stabilizing rod 772 fixedly connected to both ends of the lead screw 771 and the inner wall of the groove 73; a translation plate 773, which is sleeved on the stabilizing rod 772, the lead screw 771 passing through the translation plate 773, a second power component 774 installed on the translation plate 773, and a drive gear 775 fixedly connected to the output shaft of the second power component 774; a threaded cylinder 776, which is rotatably mounted on the translation plate 773 and threadedly connected to the lead screw 771, and a driven gear ring 777 that meshes with the drive gear 775 is fixed on the threaded cylinder 776; and a disassembly plate 778, which is fixedly mounted on the translation plate 773 for installing and disassembling the punch 8.

[0030] When controlling the punch 8 to move left and right, the second power component 774 is activated. The second power component 774 is a motor. The output shaft of the second power component 774 drives the drive gear 775 to rotate. The drive gear 775 drives the driven gear ring 777 and the threaded cylinder 776 to rotate on the translation plate 773. The rotation of the threaded cylinder 776 can drive the translation plate 773 to move along the lead screw 771 and the stabilizer 772. The movement of the translation plate 773 can drive the punch 8 to move left or right.

[0031] like Figure 5 As shown, in a preferred embodiment of the present invention, two of each of the following components are provided: translation plate 773, second power component 774, driving gear 775, threaded cylinder 776, driven gear ring 777, and disassembly plate 778. Both second power components 774 can work independently.

[0032] By activating the second power component 774, the punch 8 can be moved. The two punches 8 can work independently or together to punch holes in metal parts.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
