Silicon steel sheet press fitting tooling

Abstract

The invention discloses a silicon steel sheet press fitting tooling, and relates to the technical field of motor production. According to the technical scheme, the silicon steel sheet press fitting tooling is characterized by comprising a lower pressing plate, and a limiting structure is arranged on the lower pressing plate and used for limiting a silicon steel sheet in the silicon steel sheet press fitting process; and the limiting structure comprises a limiting check block capable of being rotatably adjusted, the limiting check block comprises a plurality of limiting faces used for limiting silicon steel sheets of different dimensions, and the minimum distances between the limiting faces and the rotating axis of the limiting check block are different. The silicon steel sheet press fitting tooling provided by the invention can be suitable for silicon steel sheets of various specifications, and is convenient to operate and good in stability.

Description

Technical field [0001] Technical Field The present invention relates to the production machine, in particular motor core, and more particularly, it relates to a steel sheet press-fit tooling. Background technique [0002] There are two main conventional motor core processing method, one is obtained by punching or wire cutting sheets of sheet punching, tooling and then using a secondary stacked, suitable for mass production in this way a single punching or thicker when processing core. Another silicon glue paste by pressing for the cutting line, for small quantities, thin silicon steel core and have a higher accuracy contour machining of the core. [0003] For the second processing mode, since the number of, and after coating silicon steel, silicon steel slides will press fitting, it is necessary to reserve a large allowance, such a multi-processing waste. [0004] Publication No. CN104454852A prior Chinese patent discloses a method of permanent neodymium magnets jump insulating a...

Problems solved by technology

[0009] However, the above-mentioned patent is applicable to silicon steel sheets of various sizes by moving the limit block, and there are still the following problems: 1. It is necessary to move all the limit blocks at the same time during adjustment, and it is necessary to measure the movement of each limit block distance, resulting in cumbersome operation and low efficiency; 2. The combination of the elongated hole and the matching hole makes the limit block rely on the pressing force to fix it, resulting in poor stability; 3. If the height of the limit block is fixed , the laminated thickness of the silicon steel sheet is limited by the height of the limit block, otherwise the limit block cannot limit the upper layer of silicon steel sheet. The cost is high, and the replacement is cumbersome, which affects the production efficiency; 4. In the above patent, the limit block is L-shaped, and the combination of the elongated hole and the matching hole makes the adjustment distance of the limit block limited, and the size of the applicable silicon steel sheet is also limited
