Description

Technical Field

[0001] The utility model relates to the technical field of motor component manufacturing, and more specifically to a stamping die for motor silicon steel sheets. Background Art

[0002] Silicon steel sheets have excellent electromagnetic properties and are important components for manufacturing motor cores. In order to meet the needs of assembly and to realize the production method of assembly lines, silicon steel sheets are usually placed on a stamping line during production. They are then stamped and formed by stamping dies in sequence. The last stamping die cuts the sheet to form a round silicon steel sheet. At this time, cut-off waste will remain on the outside of the silicon steel sheet. Generally, the waste is cleaned from the stamping die manually, but the manual cleaning method is relatively cumbersome. Alternatively, a blanking port is set on the stamping die for the waste to fall. The waste is easy to get stuck and is not easy to enter the blanking port, which affects the stamping operation. Utility Model Content

[0026] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] See also Figure 1-8 As shown, a stamping die for a motor silicon steel sheet comprises:

[0028] A male die 1 and a female die 2.1 are arranged above and below, and the female die 2.1 is arranged on a female die 2.1 fixing plate;

[0029] The female mold 2.1 and the male mold 1 can be molded or separated;

[0030] The fixing plate of the die 2.1 is provided with a floating member 3 at a position outside the die 2.1;

[0031] A plate 7 is placed on the die 2.1. When the die is closed, the plate 7 is formed into a silicon steel sheet 7.1 in the forming area of ​​the die 2.1.

[0032] When the mold is separated, the floating part 3 is pushed upward to lift the front end of the waste material 7.2 upward, so that the waste material 7.2 has an inclined structure with a high front end and a low tail end;

[0033] The stamping die for the motor silicon steel sheet 7.1 further comprises a blowing device 4, and an air outlet 4.11 of the blowing device 4 blows air to the bottom of the waste material 7.2.

[0034] After adopting the above structure, the stamping die of a motor silicon steel sheet 7.1 of the utility model has the following advantages compared with the prior art: after mold separation, the floating part 3 on the fixed seat 2 of the die 2.1 is pushed upward, and the front end of the waste 7.2 is lifted upward, so that the waste 7.2 presents an inclined structure with a high front end and a low tail end. At this time, the output end of the blowing device 4 blows air toward the bottom of the waste 7.2. Since the waste 7.2 is inclined, the waste 7.2 can be blown away from the die 2.1, avoiding the waste 7.2 remaining on the die 2.1 to affect subsequent stamping, and there is no need to manually clean the waste 7.2.

[0035] As an improvement of the utility model, the fixing seat 2 of the die 2.1 is provided with a slope 5 inclined downward, and the position of the slope 5 is set corresponding to the position of the waste 7.2. The position of the slope 5 is preferably set corresponding to the tail end of the waste 7.2. When the floating member 3 lifts the waste 7.2, the tail end of the waste 7.2 is in the slope 5, and the waste 7.2 is inclined toward the slope 5. After the blowing device 4 blows air to make the waste 7.2 leave the floating member 3, the waste 7.2 can easily enter the slope 5, and the slope 5 can guide the waste 7.2 to the required position.

[0036] As an improvement of the utility model, there are two floating members 3, one of which is arranged on the fixed seat 2 of the die 2.1, and the other floating member 3 is arranged on the slope 5. The floating member 3 of the slope 5 is lower in horizontal height than the floating member 3 of the fixed seat 2 of the die 2.1. After the above improvement, the front end of the waste material 7.2 is supported by multiple floating members 3, so that the waste material 7.2 shakes less, and the airflow of the blowing can accurately act on the lower part of the waste material 7.2.

[0037] As an improvement of the utility model, the die 2.1, the fixing seat 2 and the slope 5 are respectively provided with matching holes 6, the floating member 3 is arranged in the matching holes 6, and a spring 6.1 is arranged between the bottom end of the floating member 3 and the bottom wall of the matching hole 6. The above improvement uses the spring 6.1 to drive the floating member 3 to be ejected upward, which has the characteristics of reliable operation and long service life.

[0038] As an improvement of the utility model, the blowing device 4 includes a side guide plate 4.2, the side guide plate 4.2 is arranged on the fixed seat 2 of the die 2.1, the side guide plate 4.2 is provided with an air outlet channel 4.1, the air outlet channel 4.1 is connected to the air inlet assembly, the air outlet 4.1 of the air outlet channel 4.1 is arranged corresponding to the front bottom of the waste material 7.2, and the air outlet direction of the air outlet 4.11 is arranged backward. The blowing direction is arranged backward, when the waste material 7.2 is tilted, the gap below the waste material 7.2 is larger, the airflow can enter more abundantly, the bottom of the waste material 7.2 is strongly acted upon by the airflow, and the waste material 7.2 can move backward quickly and accurately into the slope 5.

[0039] As an improvement of the utility model, the inner diameter of the air outlet channel 4.1 to the air outlet 4.11 is gradually reduced. After the above improvement, the air pressure of the air outlet 4.11 can be increased, so that the force acting on the bottom of the waste 7.2 under the action of the airflow is large.

[0040] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
