(Summary description)At present, almost all punches used for stamping large and small hardware parts are combined with flywheels and clutches. Through the slow speed of the flywheel and the clutch to push the punch rod, the hardware parts can be stamped; and the entire assembly plane is stamped at the same time, instantaneously The stamping area is large, and there are disadvantages of high power consumption and high noise, especially for the stamping of hardware accessories. Most hardware factories do not match their operating equipment. The use of high-power (tonnage) punches that are incompatible with the power consumption of stamping parts will not only waste equipment and electrical resources, but also cause unnecessary interference to the noise of the surrounding environment. Therefore, it is necessary to research and develop a simple KYORI punching machine suitable for hardware accessories. In order to solve the above-mentioned small punches suitable for hardware accessories stamping configuration, achieve the purpose of not wasting equipment and resources, and reducing noise interference to the surrounding environment, technicians provide a simple and small KYORI punch. The technical solution adopted by the KYORI punch is: The simple and small KYORI punching machine is mainly composed of a turbine reducer, an eccentric wheel, a punching shaft, a bushing, a spring, a frame of a punch and its fixed parts, a die and a motor. It is characterized in that: a turbine reducer is arranged above the platform on the top of the frame, an eccentric wheel is arranged on the transverse top of the turbine shaft of the turbine reducer, and a shaft sleeve perpendicular to the eccentric wheel is arranged below the eccentric wheel, and the inside of the shaft sleeve is precise The punching shaft, its spring, and the convex mold are sleeved close to the eccentric wheel to form an upper and lower operating mechanism, which is precisely matched with the concave mold fixed on the lower platform of the frame to form a punching mechanism. Through the rotation of the motor, the small V-belt on the motor drives the large V-belt on the turbine reducer and the reduction ratio between the turbine and the turbine through the V-belt, reducing the motor speed from 1450 rpm to 50-70 rpm , For the eccentric wheel to do work on the punching shaft, each eccentric wheel forms a circle. Half of the periphery of the eccentric squeezes from the lowest point to the highest point of the eccentric to the plane of the shaft head of the punching shaft to complete one punching, while the other half of the periphery of the eccentric releases the extrusion on the plane of the shaft head from the highest point to the lowest point. Under the action of the elastic force of the spring, a demoulding is completed to realize the stamping operation of hardware accessories; the frame is welded by angle iron into a frame with an upper platform, a front surface of the upper platform and a lower platform. The front surface of the upper platform is fixed to the front panel by electric welding. The front plates of the upper platform, the upper platform and the lower platform are respectively processed with screw holes for fixing and installing the worm gear reducer, the shaft sleeve and the die. The back of the concave die of the lower platform is provided with a support plate for supporting the stamping material, and the four corners of the bottom of the frame are provided with soft foot pads. The punch is made of ordinary cold-worked die steel, processed into a cylindrical shank whose one end matches the inner hole of the lower end of the die sleeve, and the other end is processed into a punch head whose bottom surface conforms to the shape and size of the stamping part. In order to prevent the stamping parts from being pressed down at the same time and reduce the power consumption of the motor and the stamping noise, the punching surface of the punch head is processed into a special-shaped inclined surface with one end slightly higher, the other end slightly lower, and the tail end is linear. The slope of the inclined surface is different. Within the range of 1-3 mm. In summary, the beneficial effects of the above-mentioned small KYORI punch: This KYORI punch solves a small punch suitable for the punching configuration of hardware accessories, does not waste equipment and resources, and reduces the noise interference to the surrounding environment; the KYORI punch has the advantages of energy saving and environmental protection. It has a certain practical value and is worthy of popularization and application.
