Description
Technical Field
The utility model is applied to the technical field of hardware stamping equipment, and particularly relates to a small stamping die.
Background
The stamping die is a special process equipment for processing materials (metal or nonmetal) into parts (or semi-finished products) in cold stamping, and is called cold stamping die (commonly called cold stamping die). Stamping is a press working method in which a die mounted on a press is used to apply pressure to a material at room temperature to cause separation or plastic deformation of the material, thereby obtaining a desired part. Traditional stamping die uses the oil hydraulic cylinder as drive arrangement, and the during operation moves down on the oil hydraulic cylinder drive until with lower mould looks adaptation to make the panel beating stamping forming on the lower mould, but the structure size of oil hydraulic cylinder is great, leads to traditional stamping die spatial configuration big, is not convenient for carry out the punching press operation under the limited condition in space. The above problems can be solved well if a small-sized press die which is simple in structure, small in size and applicable to a small space can be designed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provides a small stamping die which is simple in structure, small in size and capable of being applied to a small space.
The technical scheme adopted by the utility model is as follows: the eccentric wheel device comprises a supporting plate, an upper die, a lower die, an electric motor and an eccentric wheel, wherein the electric motor is arranged on the supporting plate and is in transmission connection with the eccentric wheel, the lower die is arranged on the supporting plate, the upper die is provided with a mounting hole, the eccentric wheel is matched in the mounting hole, and when the electric motor drives the eccentric wheel to rotate eccentrically, the upper die is in sliding fit with the supporting plate.
It is seen by above-mentioned scheme that because the rotation point of eccentric wheel is not on its centre of circle, through electric motor's drive, the eccentric wheel carries out eccentric rotation to drive go up the mould and reciprocate, it is right the sheet metal component on the lower mould carries out stamping forming. Therefore, compared with the traditional stamping die, the electric motor is adopted as the driving device, the overall size of the stamping die is greatly reduced, and the stamping die can be placed in a small space for stamping operation.
Further, the electric motor pass through drive assembly with the eccentric wheel transmission is connected, drive assembly includes speed reducer, axis of rotation and connecting axle, the electric motor with the speed reducer transmission is connected, the left end face of connecting axle is equipped with circular recess and the spacing groove that is linked together, the spacing groove is located the outer fringe of circular recess, be provided with the stopper on the output shaft of speed reducer, the output shaft adaptation of speed reducer is in the circular recess, the stopper adaptation is in the spacing groove, the right-hand member face of connecting axle is equipped with square groove, square groove is not located the central point of connecting axle right-hand member face, the left end of axis of rotation is provided with square piece, square piece adaptation is in the square groove, eccentric wheel fixed connection is in the axis of rotation. Therefore, the electric motor is matched with the speed reducer to drive the eccentric wheel to rotate eccentrically, the speed reducer plays a role in reducing the rotating speed and increasing the torque, the upper die has certain stamping force in the downward moving process, and the sheet metal part on the lower die is ensured to be stamped and formed. In addition, the square groove is not positioned in the center of the right end face of the connecting shaft, the square block on the rotating shaft is matched in the square groove, and the eccentric wheel is fixedly connected to the rotating shaft, so that when the electric motor drives the connecting shaft to rotate, the eccentric wheel can be driven to rotate eccentrically.
Further, the transmission assembly further comprises a bearing sleeve and two bearings, the bearing sleeve is fixed to the supporting plate, the bearings are sleeved on the connecting shaft, and the bearing sleeve is sleeved on the bearings. Therefore, the bearing can reduce the friction coefficient of the connecting shaft in the rotating process and ensure the revolution precision.
Further, go up the mould and be in through two slide rail set sliding fit in the backup pad, two slide rail set is located respectively the left and right sides of backup pad, slide rail set includes slide rail and two sliders, the slide rail is vertical to be set up in the backup pad, the slider sets up go up the mould, slider sliding fit is in on the slide rail.
