Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of stamping dies, and in particular relates to a stamping die for household appliances which can effectively reduce the impact of die closing. Background Art
[0002] A stamping die is a pressure processing method that uses a die installed on a press to apply pressure to the material to cause it to separate or plastically deform, thereby obtaining the required parts. It is relatively common in industrial production, and some parts of home appliances that we are familiar with are also formed by stamping.
[0003] Publication (announcement) number: CN217252113U. The utility model discloses a stamping die for household appliances that can effectively reduce the impact of mold closing. The technical solution is: it includes a base, a support platform is fixedly connected to the top of the base, a movable platform is arranged on the top of the support platform, and a pressure-resistant mechanism is arranged on the top of the base, the pressure-resistant mechanism includes a first slider, a second slider, two first connecting rods and two second connecting rods, a first slide groove is opened on one side surface of the movable platform, the first slider is slidably connected to the movable platform through the first slide groove, and first round rods are fixedly connected to both ends of the first slider. The beneficial effect of a stamping die for household appliances that can effectively reduce the impact of mold closing is: by setting the pressure-resistant mechanism, the movable platform can be buffered by the third spring, the two first springs and the two second springs respectively, thereby effectively reducing the impact force during mold closing, reducing the wear of the upper mold base and the lower mold base, thereby improving the service life of the equipment and reducing the maintenance cost.
[0004] After analysis, it is found that the solution can be realized by using multiple groups of springs for buffering protection. However, when stamping, there is still a moment when there is a large impact force. Stamping will generate a strong acceleration, thereby generating a strong pressure. This pressure is often the main cause of damage between the molds. Once the pressure is high, the mold will be damaged. However, the pressure is difficult to buffer at the moment when the spring is used for buffering. In view of the above problems, the solution needs to be optimized and improved.

[0027] As a technical optimization solution of the utility model, a reinforcing rod 19 is rotatably connected between the support rods 8, and a buffer auxiliary mechanism is provided on the reinforcing rod 19;
[0028] From the above description, it can be seen that the reinforcing rod 19 can improve the stability between the supporting rods 2 8 , thereby improving the stability between the supporting rods 1 6 .

[0038] It can be seen from the above description that the warning light 28 can better prompt the workers to perform operations.
[0039] Working principle:
[0040] When the electric hydraulic rod 3 drives the upper mold 17 to move downward, the lower mold 18 contacts the upper mold 17, and at the same time, the pressure of the electric hydraulic rod 3 drives the movable plate 5 to move downward. Through the activities of the support rod 1 6 and the support rod 2 8, accompanied by the elastic force of the spring 1 14, the spring 2 22 and the spring 3 24, the movable plate 5 can move downward smoothly through the buffering of the lateral and vertical pressures, so as to buffer the impact on the lower mold 18 on the movable plate 5; as a protective measure, if the electric hydraulic rod 3 presses downward too fast, the connecting rope 16 is instantly subjected to a large pulling force generated by the high acceleration, so that the connecting rope 16 is disconnected. After disconnection, under the elastic force of the spring 1 14, the slide plate 13 is quickly pushed onto the pressure sensor 12. After the pressure sensor 12 senses it, it sends a corresponding electrical signal through the alarm light 28 to notify the worker to adjust the overall stamping data and protect the upper mold 17 and the lower mold 18 in time.
