Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a stamping die device for motor iron cores. Background Technology

[0002] The motor core is a key component in an electric motor, mainly used for magnetic conduction and coil support. Its performance directly affects the efficiency and operational stability of the motor. The manufacturing of the motor core is a precise and multi-step process, mainly including material selection, stamping, stacking, heat treatment, and surface treatment. For different models of motor cores, all molds need to be replaced, resulting in high production costs. Furthermore, a large amount of heat is generated during the stamping process of the motor core, causing the mold temperature to rise, which may lead to deformation or damage and reduce the service life of the mold. Therefore, a motor core stamping die equipment is proposed. Utility Model Content

[0005] A water inlet pipe is inserted into one side of the base, and a first drain hole is provided on the inner side of the mounting groove away from the water inlet pipe. There are multiple first drain holes.

[0006] By adopting the above technical solution, cooling water is introduced into the mounting groove through the water inlet pipe. The cooling water circulates naturally in the mounting groove, carrying away the heat generated by the stamping plate during the stamping process, and is discharged through the first drain hole and the second drain hole, forming an efficient cooling circulation system. The continuous flow of cooling water can effectively reduce the temperature of the stamping plate and prevent stamping plate deformation, mold wear or product quality degradation caused by high temperature.

[0007] When replacing or installing the stamping plate, the positioning rod and positioning hole allow for accurate installation on the base, which not only facilitates the installation of the stamping plate but also ensures the precision of the stamping operation.

[0008] Specifically, the top surface of the base has a slot for inserting the bottom of the dust cover, and the water inlet pipe passes through the slot and communicates with the interior of the mounting groove.

[0009] By adopting the above technical solution, the dust cover is installed on the top of the base through the slot, which can play a role in dust prevention and protection of the inside of the stamping groove, and prevent debris and dust from falling into the stamping groove when the stamping equipment is not in use, thus affecting the stamping quality of the motor core.

[0010] Specifically, the base has a second drain hole on the side away from the water inlet pipe. There are multiple second drain holes. The slot has a drainage channel inside. There are multiple drainage channels. The first drain hole and the second drain hole are connected through the drainage channel.

[0011] By adopting the above technical solution, the drainage channel allows the cooling water in the mounting slot to flow from the first drainage hole into the second drainage hole, and finally be discharged from the interior of the base through the second drainage hole.

[0012] Specifically, a connector is fixedly installed at the top of the base. The connector consists of multiple parts, and the interior of each connector is used for bolts to pass through.

[0013] Specifically, bolt holes are provided on opposite sides of the stamping plate, and there are multiple bolt holes, which are adapted to fit bolts.

[0014] By adopting the above technical solution, the bolts can be passed through the connector and bolt holes in sequence to fix the stamping plate and the base.

[0015] Specifically, the top surface of the stamping plate is provided with a stamping groove, and there are multiple stamping grooves. Handles are fixedly connected to the opposite sides of the stamping plate.

[0016] By adopting the above technical solution, the stamping groove is used for stamping and positioning of the motor core, and the handle facilitates the handling of the stamping plate.

[0017] The beneficial effects of this utility model are:

[0018] (1) The motor core stamping die equipment described in this utility model introduces cooling water into the installation groove through the water inlet pipe. The cooling water flows naturally in the installation groove, carrying away the heat generated by the stamping plate during the stamping process, and is discharged through the first drain hole and the second drain hole, forming an efficient cooling circulation system. The continuous flow of cooling water can effectively reduce the temperature of the stamping plate and prevent the stamping plate from deforming, the die from wear, or the product quality from deterioration due to high temperature.

[0019] (2) The motor core punching die equipment described in this utility model can accurately install the stamping plate on the base by setting the positioning rod and positioning hole when the stamping plate is replaced and installed. This not only facilitates the installation of the stamping plate but also ensures the accuracy of the stamping operation. Attached Figure Description
