Motor iron core demolding tool and demolding method

Abstract

The invention discloses a motor iron core demolding tool and demolding method, the tool comprises a hydraulic oil cylinder, a demolding pull rod, a base and a clamping plate, the hydraulic oil cylinder is installed on the base, and a piston rod of the hydraulic oil cylinder is connected with the demolding pull rod; the clamping plate is fixedly mounted on the demolding pull rod; and the clamping plate is used for transmitting the pulling force of the hydraulic oil cylinder and pulling the laminated film out of the iron core. The motor iron core demolding tool is simple in structure, convenient to operate and low in cost; and safe and reliable demolding can be ensured. According to the motor iron core demolding method, in the operation process, after the iron core is placed on the demolding support, the piston rod of the hydraulic oil cylinder supports the overlying mold from the bottom plate, the overlying mold is prevented from falling down, the overlying mold is always synchronous with the demolding pull rod, potential safety hazards existing in the demolding process are effectively prevented, and the safety of demolding of the iron core is improved.

Description

technical field [0001] The invention belongs to the technical field of motor iron core production, and in particular relates to a mold-removing tool and a mold-removing method for a motor iron core. Background technique [0002] During the motor manufacturing process, the stator and rotor cores are laminated with silicon steel sheets. After the lamination is completed, the laminated mold is withdrawn from the core. At present, there are two methods for the core to be withdrawn from the mold, namely: [0003] The first method: using a crane to lift the iron core to remove the mold: fix the laminated mold on the bottom plate of the hydraulic press, lift the iron core by a crane, and lift the iron core out of the laminated mold. This method of demoulding violates the provisions of the "Safety Regulations for Hoisting Machinery", and the design of the hoisting elements (screw holes) on the iron core generally only considers the weight of the iron core, and can only be used for l...

AI Technical Summary

Problems solved by technology

[0005] 1. In the process of ejecting the mold, sometimes it is necessary to use the superposition of high-speed rails to increase the support height, and the iron core is easy to fall over, posing a safety hazard

[0006] 2. After hoisting the iron core with laminated dies to the support, the operator needs to disassemble the sling at high altitude, which poses a safety hazard

[0007] 3. During the process of dismantling the sling, the stacking mold may fall down (there should be no support under the stacking mold), which poses a safety hazard to the operator

[0008] 4. The stacking mold is suspended at high altitude, and it may fall down before or during the pressing process, which will have a greater impact on the workbench of the hydraulic press, which will affect the use of the equipment; and the stacking mold may also fall after falling. Overturned, resulting in the overturning of the iron core, there is a great potential safety hazard
