Description

Technical Field

[0001] This utility model relates to the field of stamping armature shaft processing technology, specifically an auxiliary demolding device for stamping armature shaft processing. Background Technology

[0002] The structure of an armature shaft can be described from the following aspects: Materials: Armature shafts are typically made of high-quality carbon structural steel and other metallic materials to ensure strength and durability. Connection Methods: The armature shaft and the core are connected in various ways, including knurled shafts, heat-fitted shafts, and keyed shafts. Knurled shafts are mostly used in small motors, heat-fitted shafts are tightly connected to the core through interference fit, and keyed shafts provide a more robust connection and are suitable for large motors. Shaft Extension Shape: Armature shaft extensions include cylindrical shaft extensions, conical shaft extensions, and shafts with half-couplings. Cylindrical shaft extensions are easy to machine and widely used; conical shaft extensions are easy to install and remove and are suitable for special motors; shafts with half-couplings are mainly used in large motors.

[0003] Patent Publication No.: CN216096083U. This utility model discloses an auxiliary demolding device for stamping armature shaft processing, including a base, a column fixedly connected to the top of the base, a housing fixedly connected to the top of the column, a motor fixedly connected to the top of the housing, a first bevel gear rotatably connected inside the housing, the first bevel gear being fixedly connected to the output end of the motor, a reciprocating screw rotatably connected inside the housing and below the first bevel gear, and a second bevel gear fixedly connected to the outside of the reciprocating screw. The beneficial effects achieved by this utility model are: it can automatically pick up and collect the armature shaft after stamping, which not only speeds up work efficiency and reduces the labor intensity of workers, but also prevents workers from directly contacting the armature shaft, thereby avoiding the situation where burrs on the armature shaft cause injury to the workers' hands, achieving the purpose of automatic demolding, and improving the stability of the transverse rod movement.

[0004] Therefore, the auxiliary demolding device needs to be redesigned and modified to effectively prevent the current use of a single electromagnet for adsorption. However, since the bottom of the electromagnet is flat, the adsorption effect is poor for cylindrical workpieces with armature shafts, which can easily lead to them falling off and result in low safety. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide an auxiliary demolding device for stamping armature shaft processing, which has the advantage of facilitating workpiece removal. This solves the problem that in current stamping processing, stamping dies are used for processing, and the armature shaft workpiece is currently removed manually. However, when manually removing the workpiece, there are processing burrs on the surface of the armature shaft, making manual removal inconvenient and with low safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary demolding device for stamping armature shaft processing, comprising an auxiliary demolding device body, a bracket fixedly connected to the bottom of the auxiliary demolding device body, a rotating rod vertically movably connected inside the auxiliary demolding device body, a worm gear fixedly connected to the surface of the rotating rod, a worm engaging the back of the worm gear, a motor fixedly connected to the right side of the worm, the bottom of the motor fixedly connected to the bottom of the inner wall of the auxiliary demolding device body, an adsorption component provided on the surface of the rotating rod, and a sliding groove provided on the back of the auxiliary demolding device body.

[0007] In a preferred embodiment of this invention, the adsorption assembly includes a fixing frame, which is fixedly connected to the surface of the rotating rod. A support rod is fixedly connected to the left side of the fixing frame, and an electromagnet is fixedly connected to the bottom of the support rod.

[0008] As a preferred embodiment of this utility model, a collection box is provided on the left side of the bracket, and a caster wheel is fixedly installed at the bottom of the collection box.

[0009] As a preferred embodiment of this invention, the bottom of the electromagnet is fixedly connected with an elastic block, and the number of elastic blocks is several.

[0010] As a preferred embodiment of this utility model, the support rod has a weight-reducing opening on its front side, and the number of weight-reducing openings is several.

[0011] As a preferred embodiment of the present invention, a sealing cover is movably connected to the front of the auxiliary demolding device body, and the sealing cover is located at the top of the bracket.

[0012] In a preferred embodiment of this invention, the number of electromagnets is three, and the electromagnets are evenly distributed in a straight line.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model moves the auxiliary demolding device body to the side of the mold. When the user needs to remove the workpiece, the user starts the motor. The motor output drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel then drives the fixed frame to rotate 90 degrees, causing the fixed frame to move the support rod into the mold. This places the electromagnet on top of the workpiece. The electromagnet is then activated, generating magnetic force to attract and fix the workpiece. The motor is then started in reverse to reset the support rod. Finally, the electromagnet is turned off, allowing the workpiece to fall into the collection box for quick collection. This auxiliary demolding device body facilitates the removal of workpieces, replacing the existing manual removal method. It is safer and easier to attract and remove workpieces.

[0015] 2. This utility model, through the setting of the adsorption component, can adsorb the workpiece, making it easy to remove the workpiece. The removal efficiency is relatively high, and it is convenient to remove the workpiece quickly. Attached Figure Description

[0027] refer to Figure 3 An elastic block 11 is fixedly connected to the bottom of the electromagnet 73, and there are several elastic blocks 11.

[0028] As a technical optimization of this utility model, the bottom of the electromagnet 73 can be protected by the elastic block 11, so that the bottom of the electromagnet 73 will not collide with the stamping die and cause damage to the die, making it convenient for users to use.

[0029] refer to Figure 2 The support rod 72 has a weight reduction opening 12 on its front side, and there are several weight reduction openings 12.

[0030] As a technical optimization of this utility model, the front of the support rod 72 can be protected by the weight reduction port 12, which can reduce the manufacturing cost of the support rod 72 and make it easier for users to use.
