Description

Technical Field

[0001] The utility model relates to the technical field of stamping, in particular to a stamping device for machining a motor stator. Background Art

[0002] The motor stator is an important part of motors such as generators and starters. The stator consists of three parts: stator core, stator winding and frame.

[0003] Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet metal to deformation force in the die and deform it, thereby obtaining product parts with certain shapes, sizes and performances. Sheet metal, die and equipment are the three elements of stamping. Stamping is a metal cold deformation processing method, so it is called cold stamping or sheet metal stamping, or stamping for short. It is one of the main methods of metal plastic processing (or pressure processing);

[0004] Some stamping equipment uses the method of buffering the entire equipment when performing buffering. For example, a buffer structure is set at the bottom of the supporting legs of the equipment. This can only prevent the vibration from being transmitted to other equipment, but the entire equipment still shakes during the stamping process.

[0005] During the stamping process, the die is in direct contact with the object. Excessive stamping pressure can cause direct damage to various parts of the object and easily damage the object. Utility Model Content

[0006] The purpose of the utility model is to propose a stamping equipment for motor stator processing in response to the above-mentioned problems and shortcomings: the support block cooperates with the placement plate to support the stamping process, and the excess stamping force is buffered to prevent the entire equipment from being affected by the strong stamping force and vibrating and shaking, and the impact force of the stamping is buffered and supported at the end point of the stamping force, which facilitates stamping and prevents the stamping force from damaging objects and equipment, thereby solving the problems of overall vibration and excessive stamping pressure of the equipment.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] Preferably, the outer walls at both ends of the support rod are respectively installed on the bottom outer wall of the top plate and the top outer wall of the workbench, and a support spring is welded to the top outer wall of the counterweight block, and the top end of the support spring is installed on the bottom outer wall of the top plate.

[0010] Preferably, one end of the lever and one side of the counterweight block are provided with movable holes, and a pin shaft is inserted in the movable hole. The other end of the lever is rotatably connected to the outer wall of the side of the placement plate, and a fulcrum is installed on the top outer wall of the workbench at the bottom of the lever, and the top of the fulcrum is in contact with the bottom outer wall of the lever.

[0011] Preferably, the placement plate is located in the square hole and is rotatably connected to a bidirectional screw, and the outer walls at both ends of the bidirectional screw are screwed with clamping plates, and the two ends of the clamping plates are slidably connected to the inner outer wall of the square hole.

[0012] Preferably, a driving groove is provided on an outer wall of one side of the placement plate at the bidirectional screw, and a motor is installed in the driving groove, and the output shaft of the motor is connected to one end of the bidirectional screw.

[0013] Preferably, a hydraulic push rod is installed at the center of the top plate, and matching stamping dies are provided on the top of the placement plate and one end of the hydraulic push rod, and the stamping dies are respectively placed on the top of the placement plate and installed on one end of the hydraulic push rod.

[0014] A storage groove is provided on one side outer wall of the workbench, and side panels are installed between the workbench and the top plate at the buffer structure.

[0015] The motor and the hydraulic push rod are connected to a switch via a wire, and the switch is connected to a power source via a wire.

[0016] The beneficial effects of the utility model are:

[0017] 1. The motor drives the bidirectional screw to rotate so that the clamping plate slides in the square hole. The clamping plates are close to each other to fix the stamping die, which is convenient for fixing the die and for fixing dies of different sizes;

[0018] 2. The force generated by the hydraulic push rod acts directly on the mold and the placement plate. The levers on both sides of the placement plate pull the counterweight block up under the support of the fulcrum.

After the excess stamping pressure is buffered, the overall equipment is prevented from vibrating and shaking due to the strong impact of the stamping. The impact force of the stamping is buffered and supported at the end of the stamping pressure, which facilitates stamping while preventing the stamping pressure from damaging objects and equipment.
