Description

Technical Field

[0001] The utility model relates to the technical field of stamping processing, in particular to a stamping flip clamping structure for stamping parts. Background Art

[0002] Stamping is a metal processing method, mainly used to produce metal parts, special-shaped parts and auto parts, etc. It is to process metal sheets or strips into the desired shape by using pressure, usually at room temperature, using a mold installed on a press to apply pressure to the material to separate or plastically deform it, thereby obtaining a workpiece of the desired shape and size. Stamping is widely used in various industries such as automobiles, electronics, machinery, and home appliances. It is an indispensable technology in modern industrial production. In the stamping production process, it is often necessary to clamp the plate and flip it over before stamping. Traditionally, it is done manually, but manual work is not only dangerous but also cannot guarantee that the plate remains level after flipping.

[0003] After searching, the Chinese patent publication number CN219425462U discloses a stamping flip clamping structure for stamping parts, including a telescopic rod one, a first servo motor is installed on the top of the telescopic rod one, a turntable is connected to the top of the output shaft of the first servo motor, a clamping frame is connected to the top of the turntable, a telescopic rod two is movably sleeved inside the clamping frame, and a second servo motor is installed on the left end of the output shaft of the telescopic rod two.

[0004] In view of the problem that the above-mentioned technology lacks the function of ensuring that the device remains in a horizontal state after flipping, a stamping flip clamping structure for stamping parts is proposed. Utility Model Content

[0007] In some embodiments, one end of the clamping bracket is fixedly connected to a clamping motor, and a power output end of the clamping motor is fixedly connected to a rotating rod.

[0008] In some embodiments, one end of the rotating rod is rotatably connected to a clamping link, one end of the clamping link is rotatably connected to the clamping rod, and one end of the clamping rod is fixedly connected to an electromagnet.

[0009] In some embodiments, one side of the clamping rod is slidably connected to an iron rod, one end of the iron rod is movably connected to a parallel connecting rod, and the other side of the parallel connecting rod is rotatably connected to the clamping rod.

[0010] In some embodiments, one end of the parallel connecting rod is rotatably connected to a positioning rod, and one end of the clamping bracket is provided with a plurality of positioning holes.

[0011] In some embodiments, one end of the lifting bracket is slidably connected to a limit rod, one side of the limit rod is fixedly connected to an electric screw, and a movable end of the electric screw is threadedly connected to the lifting bracket.

[0030] When the front clamping rod 9 clamps the workpiece, the positioning push rod 11 contracts, and then the turning motor 5 can drive the transmission gear 6 to turn the workpiece over. Then the positioning push rod 11 extends and inserts one end into the front positioning groove 10 to prevent the telescopic rod 4 from deflecting during the subsequent up and down movement, causing the workpiece to be no longer level when it is punched again.

[0031] In this embodiment, one end of the clamping bracket 8 is fixedly connected to a clamping motor 12, a power output end of the clamping motor 12 is fixedly connected to a rotating rod 13, one end of the rotating rod 13 is rotatably connected to a clamping connecting rod 14, one end of the clamping connecting rod 14 is rotatably connected to the clamping rod 9, and one end of the clamping rod 9 is fixedly connected to an electromagnet 15.

[0032] When the clamping motor 12 is working, it can drive the rotating rod 13 to rotate, and then the two clamping rods 9 can be driven by the clamping connecting rod 14 to move inward along the slot at one end of the clamping bracket 8 to clamp the workpiece. After contacting the workpiece, the electromagnet 15 can work to adsorb the workpiece, further preventing the workpiece from slipping sideways during rotation.

[0033] In this embodiment, one side of the clamping rod 9 is slidably connected to an iron rod 20, one end of the iron rod 20 is movably connected to a parallel connecting rod 19, and a sliding groove is opened inside one side of the parallel connecting rod 19, so that one end of the iron rod 20 can slide inside the parallel connecting rod 19, and the other side of the parallel connecting rod 19 is rotatably connected to the clamping rod 9, one end of the parallel connecting rod 19 is rotatably connected to a positioning rod 22, one end of the positioning rod 22 is slidably connected to the clamping rod 9 and the clamping connecting rod 14, and a plurality of positioning holes 18 are opened at one end of the clamping bracket 8.
