4results about How to "Improve stamping precision" patented technology

This invention discloses a crankshaft-type dual-point multi-link press, relating to the field of press technology. It includes a support table, table body, crankshaft assembly, trolley assembly, and track. The crankshaft assembly includes a motor, transmission gears, a large gear, and a crank-connecting rod mechanism to achieve a "slow down, fast up" stamping motion. The trolley assembly includes a geared motor, drive wheels, and track cleaning blades to achieve smooth transfer of the entire machine and track cleaning. Anti-eccentric load devices are provided on both sides of the crankshaft assembly. These devices include a connecting drive assembly, a guiding and stabilizing assembly, and a clamping support assembly. This invention uses the sliding block to trigger the connecting drive assembly when it descends, which, in conjunction with the multi-link, achieves eccentric load compensation. The guiding and stabilizing assembly provides high-precision vertical guidance, and the clamping support assembly dynamically clamps the guiding structure during the stamping process. The entire machine has a compact structure, stable operation, high stamping accuracy, and strong anti-eccentric load capability.

This utility model relates to the field of metal processing technology, and in particular to a positioning structure for stamping anti-deformation thin metal sheets. It includes: two sets of clamping plates, each set of clamping plates being mounted on the side walls of an upper mold and a lower mold respectively via two magnetic structures; a lever is fixedly connected to the magnetic structure on the upper mold; a positioning mechanism is disposed on the lower clamping plate, the positioning mechanism including a mounting base fixed to the side wall of the clamping plate, a sliding opening through the side wall of the mounting base, a push rod slidably connected in the sliding opening, an elastic reset mechanism between the push rod and the mounting base, a slide rail fixedly connected to the top of the mounting base, and symmetrical sliding grooves on the inner wall of the slide rail; through the positioning mechanism on the clamping plate, the downward movement of the upper mold drives the lever to abut against the slide rail, thereby achieving automatic position adjustment of the thin metal sheet through the linkage of the rotating rod, the push rod, and the push plate.

The utility model relates to the technical field of stamping structures for precision metal structural parts, and discloses a stamping structure for precision metal structural parts, which comprises a bottom plate, a support frame is fixedly mounted at the top of the bottom plate, a hydraulic cylinder is fixedly mounted at the top of the support frame, and the lower end of the hydraulic cylinder is fixedly connected with a die pressing block. Through the arranged automatic clamping assembly, a worker starts a motor and drives a two-way lead screw to rotate, then two sets of moving blocks are driven to synchronously move in the same direction or away from each other along a guide rod, two sets of clamping plates are automatically opened and closed, and compared with traditional manual operation, the design can eliminate human errors, reduce human intervention and improve the working efficiency. Clamping deviation caused by difference of operation methods is avoided, so that stable positioning during metal part stamping is guaranteed, stamping precision is improved, the rubber pad provides flexible buffering, the surface of the metal part is prevented from being scratched, friction force is enhanced, the device can be matched with precision structural parts of different materials and shapes, and the application range of the device is widened.

This utility model discloses a precision machining device for a pneumatic punch press, relating to the field of pneumatic punch press technology. It includes a punch press base and a limiting assembly. The punch press base is an integrated structure, with a support seat at the rear end of its upper surface and a stamping fixing seat at the front end. The limiting assembly is located inside the punch press base and includes a hexagonal slide groove, a hexagonal column, a limiting slide groove, a buffer spring, a limiting piston, and a support rod. The hexagonal slide groove is formed at both ends inside the punch press base, and a hexagonal column is slidably connected inside the hexagonal slide groove. Limiting slide grooves are formed at both the front and rear ends of the hexagonal slide groove. This precision machining device for a pneumatic punch press, through the limiting assembly, allows for stable limiting of the moving stamping seat during the stamping process, thereby improving overall stamping accuracy. The cleaning assembly allows for cleaning of the inside of the mounting groove, preventing the accumulation of waste chips from affecting normal processing.
