Description

Technical Field

[0001] The utility model relates to the technical field of stamping, in particular to a burr inward-turning stamping device with an upper die adjustment function. Background Art

[0002] Burr: refers to the burr phenomenon that appears on the cut surface of tin-plated thin plates after cutting, corner cutting, notching, stamping, trimming and other processes; the stamping die in the prior art generally keeps the lower die fixed and the upper die moves downward for stamping and forming.

[0003] Chinese patent CN115673073A discloses a burr inward-turning stamping structure and its operation process, which drives the upper die assembly and the lower die assembly to move toward each other through a driving mechanism at the same time. When the lower die assembly moves upward, the lower cutting die cooperates with the fixed upper cutting die to cut the thin plate, so that a burr facing downward is formed on the edge of the thin plate. Then the upper die assembly moves downward to stamp the thin plate into a cover, so that the burr turns inward under the action of the lower die core and the upper die core. The tin plating layer of the cover will not be scratched during subsequent stacking, which has the advantages of improving the qualified rate and high work efficiency.

[0004] However, in actual operation, the upper cutting die is often adjusted in lateral position with respect to the lower cutting die as required, but the above device is not implemented, which results in inconvenience in use when processing products and thus needs to be changed.

It is arranged at the output end of the first molding device 31; the number of buffer devices 35 is multiple and they are arranged at the bottom of the translation device 33, and the upper mold knife 36 is arranged at the bottom of the buffer device 35; the number of infrared displacement sensors is a pair and they are arranged side by side at the bottom of the upper mold frame 32; the lower mold assembly 4 includes a lower mold frame 41, a lower mold knife 42 and a second molding device 43, the second molding device 43 is arranged on the mounting frame 2, the lower mold frame 41 is arranged on the top of the second molding device 43, and the lower mold knife 42 is arranged on the top of the lower mold frame 41.

[0025] During use, the operator can input the data of workpiece molding into the controller 22 as needed, place the workpiece between the upper mold assembly 3 and the lower mold assembly 4, and the controller 22 controls the translation device 33 to move the upper mold knife 36 to the specified position. The infrared displacement sensor can timely transmit the position parameters of the upper mold knife 36 to the controller 22. Through the cooperation of the first molding device 31, the second molding device 43, the infrared displacement sensor and the translation device 33, workpieces of different widths can be molded, thereby increasing the versatility of the equipment.

[0026] See also Figure 3 and Figure 4 As shown, the translation device 33 includes a second driver 331, a first translation mechanism 332, a second translation mechanism 333, a sliding frame 335 and a pulley assembly 334; the second driver 331 is arranged on the upper mold frame 32, and the output end of the second driver 331 is transmission connected to the first translation mechanism 332; the first translation mechanism 332 and the second translation mechanism 333 are mirror-imaged on both sides of the bottom of the upper mold frame 32; one side of the sliding frame 335 is slidably arranged on the first translation mechanism 332, and the other side of the sliding frame 335 is slidably arranged on the second translation mechanism 333; the pulley assembly 334 is transmission connected between the first translation mechanism 332 and the second translation mechanism 333.

[0027] When it is necessary to realize that the translation device 33 drives the upper mold knife 36 to move, the first translation mechanism 332 is driven to rotate through the second driver 331, and while the first translation mechanism 332 rotates, the second translation mechanism 333 is driven to rotate synchronously through the transmission action of the pulley assembly 334, so that the first translation mechanism 332 and the second translation mechanism 333 drive the sliding frame 335 to move, and the sliding frame 335 drives the upper mold knife 36 to move synchronously until the upper mold knife 36 moves to the specified position, thereby realizing the molding of different workpieces.

[0028] See also Figure 5 As shown, the first translation mechanism 332 and the second translation mechanism 333 have the same structure, and both the first translation mechanism 332 and the second translation mechanism 333 include a groove 3321 and a threaded rod 3322 ; the groove 3321 is arranged at the bottom of the upper mold frame 32 ; the threaded rod 3322 is rotatably arranged in the groove 3321 .

[0029] When the second driver 331 rotates, the second driver 331 drives the threaded rod 3322 to rotate synchronously. The sliding frame 335 is provided with a thread that engages with the threaded rod 3322. Therefore, when the threaded rod 3322 rotates, the sliding frame 335 moves along the direction of the threaded rod 3322, so that the sliding frame 335 drives the upper mold knife 36 to move synchronously.

[0030] See also Figure 5 As shown, the buffer device 35 includes a fixed rod 351, a retractable rod 352 and a spring 353; the fixed rod 351 is arranged at the bottom of the upper mold frame 32; the retractable rod 352 is slidably arranged on the fixed rod 351; one side of the spring 353 is connected to the fixed rod 351, and the other side of the spring 353 is connected to the upper mold knife 36.

[0031] When the upper die knife 36 and the lower die knife 42 are squeezed, the retracting rod 352 slides along the direction of the fixed rod 351, and the spring 353 is compressed until the upper die knife 36 and the lower die knife 42 cooperate to mold the workpiece, thereby improving the buffering force of the upper die knife 36 when molding the workpiece and improving the molding quality.

[0032] See also Figure 5 As shown, the first molding device 31 and the second molding device 43 have the same structure, and both the first molding device 31 and the second molding device 43 include a first driver 311, a crankshaft 312, a connecting rod 313 and a limiting mechanism 314; the first driver 311 is arranged on the mounting frame 2, and the output end of the first driver 311 is transmission-connected to the crankshaft 312; the crankshaft 312 is rotatably arranged on the mounting frame 2; one side of the connecting rod 313 is connected to the crankshaft 312, and the other side of the connecting rod 313 is hinged to the upper mold frame 32; the limiting mechanism 314 has a pair and is arranged on both sides of the upper mold frame 32.

[0033] When it is necessary to realize that the first molding device 31 drives the upper mold frame 32 to move, the first driver 311 drives the crankshaft 312 to rotate. While the crankshaft 312 rotates, it drives the connecting rod 313 to move, and then the connecting rod 313 drives the upper mold frame 32 to move synchronously. The stability of the upper mold frame 32 during the movement is effectively guaranteed by the setting of the limit assembly.

[0034] See also Figure 6 The limiting mechanism 314 shown includes a slide groove 3141 and a slider 3142 ; the slider 3142 is arranged on the upper mold frame 32 ; the slide groove 3141 is arranged on the mounting frame 2 .

[0035] When the upper mold frame 32 moves driven by the first molding device 31 , the slider 3142 moves synchronously along the slide groove 3141 , thereby ensuring the stability of the upper mold frame 32 during movement, thereby improving the processing quality.

[0036] See also Figure 1 As shown, a plurality of groups of support plates 21 are arranged in a side-by-side array on both sides of the mounting frame 2 .

[0037] By providing the support plate 21, the overall structure between the mounting frame 2 and the base 1 is effectively enhanced, thereby extending the service life of the equipment.

[0038] See also Figure 2 As shown, a rubber buffer pad 11 is also provided at the bottom of the base 1 .

[0039] By providing the rubber buffer pad 11, the buffering performance of the base 1 is effectively increased, thereby extending the service life of the device.

[0040] The first driver 311 and the second driver 331 may be a combination of a common motor and a reducer, or may be a stepper motor, a servo motor, or other devices that can be used as a driving source.
