Description

Technical Field

[0001] This utility model relates to the field of gasket manufacturing technology, and in particular to a continuous stamping die for gaskets. Background Technology

[0002] A washer is a part placed between a connected component and a nut. It is generally a flat metal ring used to protect the surface of the connected component from scratches by the nut and to distribute the pressure of the nut on the connected component.

[0003] Currently, stamping dies are widely used to produce washers. However, existing stamping dies have a drawback: a single set of dies can only produce one type and size of washer, making it difficult to meet diverse production needs. Therefore, in response to this situation, there is an urgent need to develop continuous stamping dies that allow for easy rotation and switching, facilitating the production of washers of different types and sizes, in order to overcome the shortcomings in current practical applications and meet current requirements. Utility Model Content

[0004] The purpose of this invention is to provide a continuous stamping die for washers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A continuous stamping die for washers includes a worktable, an adjustable die cavity mechanism, a lifting plate, an adjustable punch mechanism, and a feeding mechanism. A stamping table is fixed on the worktable. The adjustable die cavity mechanism includes a first motor, a first gear, a support shaft, a die plate, an inner ring die hole, an outer ring die hole, and a second gear. The first motor is fixed to the worktable, and a first gear is fixed to the output shaft of the first motor. A second gear meshing with the first gear is provided on one side of the first gear, and the second gear is fixed to the support shaft. The support shaft is rotatably connected to the worktable, and the outer side of the support shaft is evenly distributed... The fabric is fixed with three concave templates, each of which has an inner ring die hole and an outer ring die hole. The three inner ring die holes are of different sizes, and the three outer ring die holes are of different sizes. The stamping table is used to support the concave templates. The stamping table is provided with a scrap hole and a material forming hole. Two hydraulic cylinders are fixed on the worktable. The telescopic ends of the hydraulic cylinders are fixed to a lifting plate. An adjustable punch mechanism is installed on the lifting plate. The adjustable punch mechanism works in conjunction with the adjustable die mechanism. A feeding mechanism is installed on the right side of the stamping table on the worktable.

[0007] Preferably, the adjustable punch mechanism includes: a second motor, a third gear, a fourth gear, a transmission shaft, punch plates, an inner ring punch head, and an outer ring punch head. The second motor is fixed to the lifting plate, and a third gear is fixed on the output shaft of the second motor. A fourth gear is provided on one side of the third gear and meshes with it. The fourth gear is fixed on the transmission shaft, which is rotatably connected to the lifting plate. Three punch plates are evenly distributed and fixed on the outer side of the transmission shaft. The upper side of the punch plates is in contact with the lifting plate. An inner ring punch head and an outer ring punch head are fixed on the lower side of each punch plate. The three inner ring punch heads are of different sizes, and the three outer ring punch heads are of different sizes.

[0008] Preferably, the dimensions of the three inner ring punches are matched one-to-one with the dimensions of the three inner ring die holes, and the dimensions of the three outer ring punches are matched one-to-one with the dimensions of the three outer ring die holes.

[0009] Preferably, the feeding mechanism includes a conveying roller, a fifth gear, and a third motor. Two conveying rollers are rotatably connected to the worktable, and a fifth gear is fixed on each conveying roller. The two fifth gears mesh with each other. The third motor is fixed to the worktable, and the output shaft of the third motor is fixed to one of the conveying rollers.

[0010] Preferably, a waste collection box is placed on the ground below the waste hole, and a finished product collection box is placed on the ground below the finished product hole.

[0011] The beneficial effects of this utility model are as follows: When using this continuous stamping die for washers, the required inner and outer ring die holes are first selected according to the size and model of the washer to be produced. During selection, a first motor drives a first gear, a second gear, and a support shaft to rotate. The support shaft then drives three die plates to rotate, which in turn drive the inner and outer ring die holes to rotate. This ensures that the required inner ring die hole aligns with the scrap hole, and the outer ring die hole aligns with the forming hole. Similarly, the inner and outer ring punches are then adjusted. A second motor drives a third gear, a fourth gear, a transmission shaft, a punch plate, and the inner and outer ring punches to rotate. The inner and outer ring punches, which are adapted to the required inner and outer ring die holes, are rotated to be directly above them. Then, the raw material is passed between the conveyor rollers. A third motor drives the two conveyor rollers to rotate, transporting the raw material forward to the stamping table. A hydraulic cylinder drives a lifting plate to move up and down, which in turn moves the inner and outer ring punches up and down. First, the inner ring punch punches out the inner hole of the washer from the raw material, and the waste material falls through the waste hole into the waste collection box. Then, the outer ring punch punches out the outer shape of the washer from the raw material, and the formed washer falls through the forming hole into the forming collection box. In summary, this invention offers convenient rotation switching, facilitating the production of washers of different sizes and models. Attached Figure Description
