Description

Technical Field

[0001] The invention relates to the technical field of stamping processing, and in particular to a stamping device for processing non-standard metal parts. Background Art

[0002] Metal non-standard stamping, that is, the production process of non-standard stamping parts, refers to a stamping processing method that does not follow unified standards and specifications, but is designed and manufactured according to the customer's specific needs, uses or design drawings; this processing method is very common in modern manufacturing, especially when highly customized and special shapes and sizes of parts are required.

[0003] Stamping is a processing method that applies pressure to metal sheets through a die to cause plastic deformation, thereby obtaining a workpiece of the desired shape and size. In the stamping of non-standard parts, the design and manufacture of the die is the key link, which directly determines the shape, size and precision of the stamped parts. Non-standard parts stamping is widely used in various industries.

[0041] Working principle: When the present invention is in use, it can perform synchronous stamping on matching parts or letter parts, and can replace the upper mold 10 and the lower mold 19 at will to adapt to different matching requirements. First, when replacing the upper mold 10, manually press the lever 2 to push it into the stamping frame 1, so that the inner end of the lever 2 is inserted into the hole of the hook hole 11, and squeezes the connecting plate 12 to make the connecting plate 12 slide, and the connecting plate 12 drives the clamping rod 14 to move, so that the outer end of the clamping rod 14 contracts inwardly. While the lever 2 is pushed inwardly, the extension rod 4 drives the rack frame Ⅰ5 to push inward, and the rack frame Ⅰ5 drives the gear 8 to rotate, so that the gear 8 drives the rack frame Ⅱ6 to slide outward, so that the rack frame Ⅱ6 drives the buckle 9 to slide outward, so that the buckle 9 is separated from the limit of the upper mold 10, and then the lever 2 is pushed upward to drive the slider 3 to slide upward on the slide rail of the outer wall of the stamping frame 1 until the upper mold 10 is driven to the empty slot on the spare slot 16, and then Pull the lever 2 outward, the connecting plate 12 without the lever 2 will be reset under the action of the compression spring Ⅱ 13, so that the outer end of the clamping rod 14 extends outward, so that the clamping rod 14 is clamped on the top of the spare groove 16, and the rack frame Ⅱ 6 is reset under the action of the compression spring Ⅰ 7, driving the rack frame Ⅰ 5 to reset to prevent the upper mold 10 from falling, and then manually slide the spare groove 16, so that the spare upper mold 10 stored on the spare groove 16 moves to the position of the lever 2, and the lower limit clamp is 15 coincides with the upper limit card 17, and then the lever 2 is pushed inward and inserted into the hook hole 11 on the new upper mold 10 again, and the connecting plate 12 is pushed open, driving the clamping rod 14 to retract, and the rack frame Ⅰ5 is pushed again, and finally the buckle 9 slides outward again, and then the lever 2 is driven to pull downward until the upper mold 10 is placed in the stamping position at the lower end of the stamping frame 1, and then the lever 2 is pulled outward to make the buckle 9 clamp the upper mold 10 again, and then stamping can be carried out.

[0042] The two upper molds 10 on the stamping frame 1 are replaced independently, and all of them are described in the above steps. The replacement of the lower mold 19 can be directly taken out and replaced manually. When the stamping is completed, the stepper motor 25 is started, driving the screw rod 24 to rotate, thereby driving the balance bar 22 to slide upward, so that the balance bar 22 drives the integration frame 20 to slide upward in an arc on the arc frame 21, so that the four legs of the integration frame 20 lift the non-standard parts in the two lower molds 19, and move them closer to the middle and touch them together, and then take away the two paired parts for easy summary and placement, and then the integration frame 20 is reset to wait for the next stamping.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
