Description

Technical Field

[0001] The utility model belongs to the technical field of motor stator punching production equipment, and particularly relates to a manufacturing die for motor stator punching sheets. Background Art

[0002] The stator punching sheet, the stationary part of the turbine generator body, also known as the stator, is one of the key components of the turbine generator. It consists of a magnetically conductive stator core, an electrically conductive stator winding, and a frame structure that fixes the core and winding and forms a cooling medium channel.

[0003] Since the blades are prone to damage and need to be frequently replaced when the stator punching sheet is cut and formed, the blades of some dies are fixed and installed with screws, and the screws need to be screwed when disassembling and assembling, resulting in the problem that it is relatively troublesome to replace the vulnerable parts of the conventional manufacturing die for motor stator punching sheets.

[0004] Therefore, we propose a manufacturing die for motor stator punching sheets to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that it is relatively troublesome to replace the vulnerable parts of the conventional manufacturing die for motor stator punching sheets, and to propose a manufacturing die for motor stator punching sheets.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] The manufacturing die for motor stator punching sheets includes a mounting seat. A connecting buckle is fixedly installed at the lower part of the mounting seat. A tool holder is buckled under the connecting buckle. A thimble is slidably inserted through the mounting seat. A tension spring is connected between the mounting seat and the thimble. A spring is fixedly connected to the lower part of the mounting seat. When the hydraulic press drives the mounting seat to press down, the tool holder is driven by the mounting seat to extrude and cut for forming. After the mounting seat rises, the elastic force of the tension spring drives the thimble to act downward on the formed stator punching sheet to make the punching sheet fall off, and the waste is discharged by the spring; the tool holder is pulled downward to disengage the tool holder from the connecting buckle, and then a new tool holder is replaced, which is convenient for replacing the vulnerable parts.

[0008] Preferably, the mounting seat includes a first seat body, and a sliding hole is hollowed out at the lower part of the first seat body. When the target hydraulic press drives the mounting seat to press down, the tool holder is driven by the first seat body to cut the target, and the sliding hole facilitates guiding the up-and-down sliding of the thimble.

[0009] Preferably, the mounting seat further includes a reinforcing ring, and the reinforcing ring is fixedly connected to the outer periphery of the lower part of the first seat body. The reinforcing ring is used to increase the force-bearing range between the mounting seat and the tool holder.

[0010] Preferably, the mounting base further includes anti-rotation blocks which are uniformly and fixedly connected to the lower end of the first base body. By using the anti-rotation blocks to be stuck in the gaps of the tool holder, the rotation of the tool holder is prevented, and unnecessary wear between the tool holder and the first base body is reduced.

[0011] Preferably, the mounting base further includes guide blocks which are fixedly connected to the lower ends of the anti-rotation blocks. When installing the tool holder, the guide blocks are used to guide the anti-rotation blocks to be stuck at the gaps of the tool holder, facilitating the assembly of the tool holder.

[0012] Preferably, the connecting buckle includes a connecting ring and elastic buckles which are symmetrically and fixedly connected to the lower end of the connecting ring. The elastic buckles are used to fasten the tool holder to prevent the tool holder from falling off.

[0013] Preferably, the tool holder includes a second base body and a tool body, and the upper end of the tool body is fixedly connected to the lower end of the second base body. With the help of an external pliers clamped on the tool body and then moved downward, the second base body is disengaged from the connecting buckle; or with the help of a screwdriver, the second base body is pried off and then a new tool holder is replaced, facilitating the replacement of the tool holder.

[0014] In summary, the technical effects and advantages of the present utility model are as follows:

[0015] 1. When the hydraulic press drives the mounting base to press down, the tool holder is driven by the mounting base to extrude and cut into shape. After the mounting base rises, the elastic force of the tension spring drives the ejector pin to act downward on the formed stator punching sheet, causing the punching sheet to fall off; the tool holder is pulled downward to disengage the tool holder from the connecting buckle, and then a new tool holder is replaced, facilitating the replacement of vulnerable parts.

[0016] 2. When the target hydraulic press drives the mounting base to press down, the tool holder is driven by the first base body to cut the target, and the ejector pin is conveniently guided to slide up and down through the sliding hole.

[0017] 3. By using the anti-rotation blocks to be stuck in the gaps of the tool holder, the rotation of the tool holder is prevented, and unnecessary wear between the tool holder and the first base body is reduced.

[0018] 4. With the help of an external pliers clamped on the tool body and then moved downward, the second base body is disengaged from the connecting buckle; or with the help of a screwdriver, the second base body is pried off and then a new tool holder is replaced, facilitating the replacement of the tool holder.
