Description

Technical Field

[0001] The present application relates to the technical field of self-adhesive motor core processing, and in particular to a heating structure for a self-adhesive motor core stamping die. Background Art

[0002] The manufacturing of traditional motor cores mostly adopts processes such as welding, point riveting and stacking. These processes are not only inefficient, but also easily lead to high iron loss in the core, affecting motor performance. The self-adhesive motor core replaces the traditional process with a stacking structure, realizing one-time automatic stacking and forming in the mold, thereby reducing iron loss, improving motor performance, and reducing the size of the motor while ensuring power. In order to further improve the manufacturing efficiency and quality of self-adhesive motor cores, a stamping die heating structure came into being. It can accurately heat the core with coated material to ensure the smooth progress of the stacking process while ensuring the accuracy and productivity of the core.

[0003] Regarding the above-mentioned related technologies, the inventor believes that in the traditional motor core stamping die heating structure, the installation of the heating element is often complicated and time-consuming, and the stability after installation is difficult to ensure. During the heating process, due to thermal expansion and contraction or mechanical vibration, the heating element is prone to loosening or displacement, which not only affects the heating uniformity and accuracy of the mold, but may also cause damage to the mold or the quality of the produced core does not meet the standards. Moreover, in previous stamping die heating systems, heating efficiency and uniformity often become bottlenecks that restrict production efficiency and product quality. Uneven heating will cause large temperature differences between different parts of the mold, which will affect the forming effect and dimensional accuracy of the core. In addition, if the connection is not firm during the heating process, it may also cause heat leakage, reduce heating efficiency, and even cause safety hazards. Utility Model Content

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0030] Example

[0031] A self-adhesive motor core stamping die heating structure, referring to Figure 1 and Figure 2 , including a shell 1, a plurality of limit plates 26 are fixedly welded on both sides of the inner surface of the shell 1, these limit plates 26 are tightly fitted with the heat conducting plate 20, ensuring that the heat conducting plate 20 is stably fixed inside the shell 1, and fixing plates 25 are respectively provided on both sides of the shell 1. These fixing plates 25 are tightly threadedly connected with the fixing screw grooves 23 on the shell 1 through a plurality of fixing bolts 22, thereby firmly fixing the heat conducting plate 20 and the heating mechanism 3 in the shell 1.

[0032] Reference Figure 2 The use of the limiting groove 21 and the limiting block 27 can effectively prevent the heat conducting plate 20 from shifting or deforming during the heating process, ensuring the uniformity of heating and the stability of the mold, thereby improving production efficiency and product quality. The evenly spaced fixing bolts 22 can evenly and tightly connect the fixing plate 25 to the shell 1, avoiding loosening or deformation caused by uneven force. The limiting slot 24 provides an additional fixing point for the heating tube 30, further enhancing the stability of the connection between the heating tube 30 and the shell 1.

[0033] Reference Figure 3 The heating mechanism 3 consists of two heating tubes 30, which are respectively inserted into the heating groove 38 opened on one side of the heat conducting plate 20 so that heat can be directly transferred. A connecting port 31 is fixed at one end of the heating tube 30 and is connected to an external power supply through a connecting line 36. In order to stabilize the connecting port 31, two threaded ports 32 are provided on one of the fixing plates 25. The outer surface of the threaded port 32 is provided with an extrusion groove 33. By tightening the threaded ring 34, the oblique groove 35 on its inner surface cooperates with the extrusion groove 33 to generate a tightening force, firmly fixing the connecting port 31 and the connecting line 36 to one side of the fixing plate 25, ensuring the safety and stable operation of the heating tube 30.

[0034] Reference Figure 3 The connecting groove 28 enables the connecting port 31 to be easily and accurately inserted into the housing 1. The engagement groove 37 cooperates with the connecting port 31 to provide an additional fixing point for the connecting wire 36, preventing the connecting wire 36 from falling off due to loosening or vibration during the heating process. The threaded port 32 made of soft metal can be slightly deformed when the threaded ring 34 is tightened, forming a tighter fit with the extrusion groove 33 and the bevel groove 35.

[0035] The implementation principle of the embodiment of the present application is: through the fixing mechanism 2, the fixing plate 25 is attached to the two sides of the shell 1, and the fixing bolts 22 are matched with the fixing screw grooves 23, so that the fixing plate 25 can be fixed on both sides of the shell 1. The heat conducting plate 20 arranged inside the shell 1 can be limited by the limiting groove 21 and the limiting block 27, and the limiting plate 26 inside the shell 1 can prevent the heat conducting plate 20 from loosening. The heat conducting plate 20 cooperates with the heating mechanism 3 to heat the shell 1 and the stamping groove 4 at the upper end.

[0036] The use of the limiting groove 21 and the limiting block 27 can effectively prevent the heat conducting plate 20 from shifting or deforming during the heating process, ensuring the uniformity of heating and the stability of the mold, thereby improving production efficiency and product quality. The evenly spaced fixing bolts 22 can evenly and tightly connect the fixing plate 25 to the outer shell 1, avoiding loosening or deformation caused by uneven force. The limiting slot 24 provides an additional fixing point for the heating tube 30, further enhancing the stability of the connection between the heating tube 30 and the outer shell 1.

[0037] Through the heating mechanism 3, the two heating tubes 30 are inserted into the heating groove 38 on the heat conducting plate 20 through one side of the shell 1. Then, the fixing mechanism 2 is used to fix the connecting port 31 so that it can be limited by the engaging groove 37. Then, the threaded ring 34 on the connecting line 36 is twisted so that the threaded ring 34 can rotate on the outer surface of the threaded port 32. The connecting line 36 can be fixed by extrusion deformation in conjunction with the inclined groove 35 and the extrusion groove 33, so that the heat conducting plate 20 can be heated and heated through the heating tube 30.

[0038] The connecting groove 28 enables the connecting port 31 to be easily and accurately inserted into the housing 1. The engagement groove 37 cooperates with the connecting port 31 to provide an additional fixing point for the connecting wire 36, preventing the connecting wire 36 from falling off due to loosening or vibration during the heating process. The threaded port 32 made of soft metal can be slightly deformed when the threaded ring 34 is tightened, forming a tighter fit with the extrusion groove 33 and the bevel groove 35.
