Abstract
The invention relates to a die for a shutter. The die for the shutter comprises an upper die and a lower die, which are matched for use, and the die for the shutter is characterized in that the upper die comprises a long die body, a shearing sharp cutting edge along the length direction of the long die body is arranged on the edge at the bottom of the long die body, and a die handle is arranged at the middle of the top of the long die body; and a shearing sharp part corresponding to the shape of the shearing sharp cutting edge is concavely arranged at the top of the lower die. The die for the shutter is simple in structure and higher in safety, the shutter manufactured by the die can meet the protection level of motor IP23, and water can be prevented from entering into a motor and further drenching a motor winding when the motor is exposed to the rain, thereby greatly improving the safety of the motor and laying a foundation for mass production of Y series three-phase asynchronous motors (IP23).
Description
Technical field
The invention belongs to the motor manufacturing technology field, specifically relate to a kind of Y series threephase asynchronous shutter punch die.
Background technology
Needs along with market; The client is growing to the demand of Y series threephase asynchronous (degree of protection is IP23); Because the wind path of motor circulates with outside air; Simultaneously reach the requirement of shelter of IP23 again, so on motor, be provided with the passage that shutter exchanges with air as motor.Shutter in the past all is designed to latticed; But the degree of protection requirement that the shutter of this structure does not reach IP23 under the environment for use out of doors; Motor has water to get into motor when drenching with rain easily and causes motor windings to be drenched, and causes the motor short circuit, when serious even cause burn-down of electric motor.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art; A kind of simple in structure, Y that security is higher series threephase asynchronous shutter punch die is provided; The shutter that utilizes this punch die to make can satisfy the degree of protection of motor I P23; When drenching with rain, do not have water yet and get into motor and motor windings is drenched, improved the security of motor greatly, produce in batches for Y series threephase asynchronous (IP23) and lay a good foundation.
According to technical scheme provided by the invention: the shutter punch die; Comprise the upper die and lower die that are used; It is characterized in that: said patrix comprises long die body, and long die body bottom margin is provided with the shearing cutting edge along long die body length direction, and long die body crown center is provided with die shank; The top of said counterdie is concaved with and the corresponding shearing cutting edge of a knife or a sword of said shearing cutting edge shape mouth.
As further improvement of the present invention, the transverse shape of said shearing cutting edge all is to be circular arc with the transverse shape of shearing the cutting edge of a knife or a sword mouth.
As further improvement of the present invention; Said counterdie comprises first lower mold body and second lower mold body; The top of first lower mold body is provided with the elongated slot that the cross section is a circular arc; First lower mold body and second lower mold body connect as one with screw, and the side of the elongated slot of the first lower mold body top and second lower mold body constitutes described shearing cutting edge of a knife or a sword mouth.
The present invention compared with prior art; Advantage is: the present invention is simple in structure, security is higher; The shutter that this punch die is made can satisfy the degree of protection of motor I P23; When drenching with rain, do not have water yet and get into motor and motor windings is drenched, improved the security of motor greatly, produce in batches for Y series threephase asynchronous (IP23) and lay a good foundation.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the right view of patrix among Fig. 1.
Fig. 3 is the vertical view of counterdie among Fig. 1.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure, said shutter punch die mainly is made up of patrix that is used 1 and counterdie 2, and said patrix 1 comprises long die body 1a, and long die body 1a bottom margin is provided with the shearing cutting edge 1c along long die body 1a length direction, and long die body 1a crown center is provided with die shank 1b; The top of said counterdie 2 is concaved with and the corresponding shearing cutting edge of a knife or a sword of said shearing cutting edge 1c shape mouth 2a.
Like Fig. 1 ~ shown in Figure 3, the transverse shape of said shearing cutting edge 1c all is to be circular arc with the transverse shape of shearing cutting edge of a knife or a sword mouth 2a.The shutter that the punching out of this structure institute is come out is simple; Can satisfy the degree of protection of motor I P23; When drenching with rain, do not have water yet and get into motor and motor windings is drenched, improved the security of motor greatly, produce in batches for Y series threephase asynchronous (IP23) and lay a good foundation.
Like Fig. 1, shown in Figure 3; Said counterdie 2 is made up of the first lower mold body 2b and the second lower mold body 2c; The top of the first lower mold body 2b is provided with the elongated slot that the cross section is a circular arc; The first lower mold body 2b and the second lower mold body 2c connect as one with screw, and the elongated slot of the first lower mold body 2b top and the side of the second lower mold body 2c constitute described shearing cutting edge of a knife or a sword mouth 2a.The counterdie 2 of this structure is made simple, and production cost is lower.
During concrete the application, certain thickness steel plate (being generally 3mm) is tiled on the counterdie 2, as required first window of punching out; After punching out was accomplished, first window with punching of the steel plate pasted the edge that hangs over counterdie 2 again, relied on this location, edge; Second window of punching out again; Paste the edge that hangs over counterdie 2 to second window then, the 3rd window of punching out again, by that analogy.
