Description

Technical Field

[0001] The invention relates to the technical field of handicraft punching processing, in particular to a punching device used for processing metal handicrafts. Background Art

[0002] Metal crafts refer to commodities with certain artistic attributes that are mass-produced using mechanized tools. They have certain decorative and practical values. Crafts generally have specific shapes and sizes, and some small crafts are often punched after production to facilitate consumers to carry or wear them using key chains or lanyards. The punching devices currently used generally punch the plate surface or sideways. When processing spherical metal crafts, due to the curvature of their surface, the punch is prone to slide and dislocate relative to the craft itself during the punching process, affecting the punching effect.

[0003] Moreover, in the production process of spherical metal crafts, two hemispheres are generally made by using a mold, and then the two hemispheres are punched, and then the two are welded and fixed. However, when punching the spherical metal crafts, the existing punching device cannot directly fix the two hemispheres, and generally needs to perform punching processes in sequence, which has low processing efficiency. Some punching devices can fix the welded spherical metal crafts by upper and lower clamping, and then perform stamping from both sides. Although this processing method can improve efficiency, the debris generated during the punching process is easily retained in the spherical metal crafts, making it difficult to discharge, and the punching position cannot be adjusted at will, which affects the processing effect. Therefore, it is necessary to design a punching device for metal craft processing. Summary of the invention

DETAILED DESCRIPTION

[0039] Reference Figures 1 to 14 A punching device for metal handicraft processing includes a fixed table 1 and two process spheres 2. Both process spheres 2 are hollow hemispherical and are made by processing with a specific mold, which will not be elaborated in detail herein. The device also includes a spherical mold 5 installed on the fixed table 1. The spherical mold 5 is a hollow sphere and has a plurality of alignment holes 6 evenly arranged thereon. The diameter of the alignment holes 6 is slightly larger than the diameter of the punch 14. The existence of the alignment holes 6 is used to allow the debris generated during the punching process to fall off the process sphere 2 smoothly and enter the spherical mold 5, thereby avoiding the problem of poor product quality caused by the debris being retained in the process sphere 2.

[0040] A support sleeve is rotatably mounted on the fixed platform 1, and a mounting platform 3 is fixedly mounted on the support sleeve. A base 4 is fixedly mounted on the mounting platform 3 by multiple bolts, and a support rod is fixedly mounted between the base 4 and the spherical mold 5. A discharge port is opened at the bottom of the spherical mold 5, and the discharge port is used to discharge the debris in the spherical mold 5 after punching. An n-shaped frame is fixedly mounted on the bottom of the fixed platform 1, and a rotating motor is fixedly mounted on the n-shaped frame. A driving shaft is fixedly mounted on the output end of the rotating motor, and a fixed gear is fixedly mounted on the driving shaft. A fixed gear ring meshing with the fixed gear is fixedly mounted on the support sleeve at the bottom. The rotating motor can specifically adopt a motor that can only rotate in one direction commonly seen in daily life. When the rotating motor is working, the fixed gear can be driven to rotate by the driving shaft, and then, under the cooperation of the fixed gear and the fixed gear ring, the mounting platform 3 drives the spherical mold 5 to rotate horizontally on the fixed platform 1, and the horizontal angle of the process sphere 2 fixed thereon is adjusted, so as to facilitate punching at different horizontal positions thereon. The rotating motor, the driving shaft, the fixed gear, the fixed gear ring and the support sleeve are not marked in the figure.

[0041] A mounting plate 9 is fixedly mounted on the fixed platform 1, and two brackets 7 are fixedly mounted on the fixed platform 1, and a connecting plate 8 is fixedly mounted between the two brackets 7, and the connecting plate 8 is fixedly connected to the mounting plate 9. With the cooperation of the two brackets 7 and the connecting plate 8, the fixation of the mounting plate 9 on the fixed platform 1 can be guaranteed, and the mounting position of the bracket 7 is also convenient for taking and placing the process sphere 2 on the fixed platform 1.

[0042] Two arc plates 10 are slidably mounted on the mounting plate 9, and two arc grooves 27 are provided on the mounting plate 9. Guide columns 28 that slide in cooperation with the corresponding arc grooves 27 are fixedly mounted on the two arc plates 10. With the cooperation between the guide columns 28 and the arc grooves 27, the moving direction of the arc plate 10 on the mounting plate 9 can be effectively limited. At the same time, a positioning plate can be arranged on the guide column 28, and an arc groove that slides in cooperation with the positioning plate can be arranged on the side wall of the arc groove 27. The front and rear positions of the positioning plate are limited by the arc grooves, thereby improving the connection stability between the arc plate 10 and the mounting plate 9.

[0043] An angle deflection assembly is installed between the mounting plate 9 and the two arc plates 10, and the angle deflection assembly includes a connecting gear 25 rotatably mounted on the mounting plate 9, arc racks 26 are fixedly mounted on the two arc plates 10, and the two arc racks 26 are respectively meshed with the upper and lower sides of the front and rear ends of the connecting gear 25, and a servo motor 23 is fixedly mounted on the back of the connecting plate 8, and a driving gear 24 is fixedly mounted on the output end of the servo motor 23 through a driving rod, and the driving gear 24 is meshed with the middle section of the connecting gear 25. When the servo motor 23 is working, the connecting gear 25 can be driven to rotate by the driving gear 24. At this time, under the meshing effect of the connecting gear 25 and the two arc racks 26, the two arc plates 10 can be brought close to or separated from each other on the mounting plate 9.

[0044] A mounting seat 11 is fixedly installed on the two arc-shaped plates 10, and a hydraulic cylinder 12 is fixedly installed on one end of the two mounting seats 11 close to the spherical mold 5, and a push column 13 is fixedly installed on the output end of the two hydraulic cylinders 12, and a punch 14 is fixedly installed on the end close to the two push columns 13. When the arc-shaped plate 10 moves on the mounting plate 9, due to the movement direction limitation of the arc groove 27 and the guide column 28, it can be regarded that the hydraulic cylinder 12 has an angular deflection on the vertical plane. Therefore, the vertical punching position of the punch 14 relative to the process sphere 2 can be adjusted. In conjunction with the horizontal rotation of the spherical mold 5, corresponding punching processing can be performed at different positions on the process sphere 2 at different angles, effectively improving the application range of the punching processing.

[0045] The ends of the two push posts 13 that are close to each other are both installed with a positioning cover 18 through a sliding assembly. The sliding assembly consists of a housing chamber 16, a connecting post 17, a plurality of guide grooves 20, a plurality of guide blocks 21, and a plurality of compression springs 22. The housing chamber 16 is provided at the end of the push post 13 that is away from the mounting seat 11. The connecting post 17 is slidably installed in the housing chamber 16, and the connecting post 17 is fixedly connected to the positioning cover 18. The plurality of guide grooves 20 are provided on the side walls of the housing chamber 16. The plurality of guide blocks 21 are respectively slidably installed in the corresponding guide grooves 20, and each guide block 21 is fixedly connected to the connecting post 17. The plurality of compression springs 22 are respectively installed in the corresponding guide grooves 20 and the corresponding guide grooves 20. Between the guide blocks 21, after completing the punching position and angle of the punch 14 relative to the process sphere 2, start the hydraulic cylinder 12, and the push column 13 drives the punch 14 and the positioning cover 18 to approach the process sphere 2. Then, the positioning cover 18 first contacts the process sphere 2 and under the reaction force, the guide block 21 overcomes the elastic force of the compression spring 22 and moves into the guide groove 20. Then, the continued movement of the push column 13 allows the punch 14 to pass through the positioning cover 18 to complete the punching process of the process sphere 2. Due to the presence of the positioning cover 18, the spherical mold 5 can effectively cooperate with the spherical mold 5 to protect the area around the punching position of the process sphere 2 to avoid the problem of deformation of the process sphere 2 during the punching process.

[0046] A spring 15 is installed between the push column 13 and the mounting seat 11, and a through hole 19 that slides with the punch 14 is opened between the connecting column 17 and the positioning cover 18. The through hole 19 is designed to allow the punch 14 to pass through the connecting column 17 and the positioning cover 18 under the continuous movement of the push column 13 to complete the punching process of the process sphere 2.

[0047] A plurality of adsorption holes are provided on the spherical mold 5, and an adsorption assembly matching the plurality of adsorption holes is installed on the fixed platform 1, and the adsorption assembly matches the two process spheres 2. The adsorption assembly consists of a fixed tube 30, a spherical seat 31, a plurality of air pipes 32 and a plurality of adsorption seats 33. The fixed tube 30 is fixedly installed at the bottom of the fixed platform 1, and the fixed tube 30 is rotatably connected to the mounting sleeve, the mounting platform 3 and the base 4. The spherical seat 31 is fixedly connected to the top of the fixed tube 30, and the spherical seat 31 is located in the spherical mold 5. A plurality of adsorption seats 33 are fixedly connected to the spherical seat 31 through corresponding air pipes 32, and each adsorption seat 33 is fixed in a corresponding adsorption hole. When the process sphere 2 is placed on the spherical mold 5, the fixed tube 30 is exhausted downward. At this time, since the adsorption seat 33 is attached to the inner wall of the process sphere 2, negative pressure will be generated in the spherical seat 31, so that the process sphere 2 can be effectively adsorbed and fixed on the spherical mold 5 by the negative pressure, so as to ensure the stability during the punching process and avoid the problem of punching misalignment.

[0048] A pressure regulating mechanism that cooperates with the fixed tube 30 is installed at the bottom of the fixed table 1. The pressure regulating mechanism consists of a pressure regulating seat 29, a piston plate 34, a pull rod 35 and a slider 36. The pressure regulating seat 29 is fixedly installed at the bottom of the fixed table 1, and the left side of the pressure regulating seat 29 is fixedly connected to the fixed tube 30. The piston plate 34 is sealingly and slidably installed in the pressure regulating seat 29, the pull rod 35 is fixedly installed on the right side of the piston plate 34, and the slider 36 is fixedly installed on the top of the pull rod 35. A slide groove 40 that cooperates with the pull rod 35 is opened on the fixed table 1. With the cooperation of the slider 36 and the pull rod 35, the slider 36 can be pulled to the left to make the piston plate 34 move to the left in the pressure regulating seat 29. At this time, the fixed tube 30 can be evacuated downward to allow multiple adsorption seats 33 to generate negative pressure to fix the process sphere 2 on the spherical mold 5.

[0049] The sliding sleeve 37 is slidably installed on the top of the slider 36, and two connecting blocks 38 are fixedly installed on the bottom of the sliding sleeve 37. The slider 36 is provided with two connecting grooves 39 that are slidably matched with the corresponding connecting blocks 38, and tension springs are installed between the two connecting grooves 39 and the two connecting blocks 38. The height of the sliding sleeve 37 is greater than the height of the slider 36, and the height of the sliding sleeve 37 is less than the sum of the heights of the slider 36 and the connecting blocks 38. Through the elastic force of the tension spring and the size design of the sliding sleeve 37, the sliding sleeve 37 can be closely attached to the surface of the fixed platform 1. At this time, the position of the pull rod 35 on the fixed platform 1 can be limited, thereby ensuring the constant air pressure in the pressure regulating seat 29. Therefore, after the adsorption and fixation of the process sphere 2 on the spherical mold 5 is completed, the fixing effect can be ensured. When the process sphere 2 needs to be removed from the spherical mold 5, it is only necessary to pull the sliding sleeve 37 upward to separate its bottom from the fixed platform 1 and then move the sliding sleeve 37 to the left to drive the pull rod 35 to move to the left through the slider 36. The operation method is simple.

[0050] In the present invention, the working principle of the punching device used for metal craft processing is as follows:

[0051] Fixing of the process sphere 2: Fix the two process spheres 2 as Figure 1 As shown, they are placed on both sides of the spherical mold 5, and then the sliding sleeve 37 is pulled upward to separate its bottom from the fixed platform 1 and then pulled to the right. At this time, the piston plate 34 is driven to move to the right in the pressure regulating seat 29 by the pull rod 35, so that the multiple adsorption seats 33 generate negative pressure to firmly adsorb the two process balls 2 on the spherical mold 5 to complete the fixing process;

[0052] Adjustment of the punching position: After the process sphere 2 is fixed, the process sphere 2 is rotated horizontally on the fixing table 1 by starting the rotating motor and the servo motor 23, and the two punches 14 are rotated vertically relative to the process sphere 2, so as to complete the adjustment of the punching position;

[0053] Punching process: After the punching position is adjusted, the two hydraulic cylinders 12 are started at the same time to make the two push pins 13 approach the corresponding process sphere 2 at the same time. During this process, the two positioning covers 18 first contact the corresponding process sphere 2 respectively, and then the two punches 14 continue to move to complete the punching process of the corresponding process sphere 2 while the push pins 13 continue to move.

[0054] Discharge of debris: After the punching process is completed, the two hydraulic cylinders 12 are first contracted to separate the two positioning covers 18 from the two process spheres 2, and then the sliding sleeve 37 is pulled upward and then pushed to the left to eliminate the negative pressure of the multiple adsorption seats 33, thereby releasing the adsorption and fixing effect between the process sphere 2 and the spherical mold 5. After that, the two punched process spheres 2 are removed from the spherical mold 5. At this time, the discharge port at the bottom of the spherical mold 5 is not blocked by the process sphere 2, and the debris dropped into the spherical mold 5 during the punching process can be smoothly discharged through the discharge port.

[0055] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
