Abstract
The utility model discloses a motor rotor punching high-speed punching die. The motor rotor punching high-speed punching die comprises a hole A female die, a hole A male die punch, a hole B female die, a hole B male die punch, wherein the hole A male die punch is a plate pulling type punch, and the working step of hole B punching is increased after the step of hole A punching. The motor rotor punching high-speed punching die is simple in structure, is reasonable in die layout, does not need to replace the hole A female die and the hole B female die, avoids the trouble of detachment, improves the use accuracy, prolongs the service life, lowers manufacturing cost, is simple and convenient to operate, and is good in applicability.
Description
Technical field
The utility model relates to a kind of motor rotor punching sheet high-speed punching mould.
Background technology
General motor rotor punching sheet High_Speed Die adopts the method for changing different pore size drift punch and matrix for same rotor punching different inner diameters size.Have mould punch and matrix dismounting trouble while changing, repeatedly repeated disassembled and assembled affects the problems such as mould and die accuracy.
The utility model content
The utility model purpose is exactly in order to make up the defect of prior art, and a kind of motor rotor punching sheet high-speed punching mould of avoiding the being dismounted for multiple times punch-die is provided.
The utility model is achieved through the following technical solutions:
A kind of motor rotor punching sheet high-speed punching mould, comprise A hole die, A hole punch, B hole die, B hole punch, and described A hole punch is the pulling-tray type drift, slides and be arranged on template body.
Described A hole punch is larger than B hole punch diameter.
Increased B hole stamping-out work step after the stamping-out work step of A hole.
Operation principle of the present utility model is: when the same rotor punching of stamping-out different inner diameters size, according to institute's stamping-out aperture, pull out required drift pumping board, drift exposes, and completes the rotor inner hole stamping-out.
The utility model has the advantages that: the utility model is simple in structure, and mold layout is reasonable, and mould need not be changed A hole, B hole drift punch and matrix, avoided the trouble of dismounting, improved the precision of using, increased the service life, reduce manufacturing cost, easy and simple to handle, applicability is good.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of motor rotor punching sheet high-speed punching mould, comprise A hole die, A hole punch 1, B hole die, B hole punch 2, and A hole punch is the pulling-tray type drift, slip is arranged on template body 3, and A hole punch is larger than B hole punch diameter.
Increased B hole stamping-out work step after the stamping-out work step of A hole.In use, as shown in Figure 2, need A, two kinds of different pore size rotor punchings of B, when stamping-out B hole shape rotor punching, A hole stamping-out work step pumping board inserts, and A hole drift does not expose, and during stamping-out, A hole drift is not worked, and by B hole drift in a rear work step, completes stamping-out; When stamping-out A hole shape rotor punching, A hole stamping-out work step pumping board is pulled out, and A hole drift exposes, and A completes in hole stamping-out (the A aperture size is greater than the B aperture size), and in a rear work step, B hole drift is not to stamping-out generation effect.
Claims (2)
1. a motor rotor punching sheet high-speed punching mould, comprise A hole die, A hole punch, B hole die, B hole punch, it is characterized in that: described A hole punch is the pulling-tray type drift, slides and is arranged on template body.
2. motor rotor punching sheet high-speed punching mould according to claim 1, it is characterized in that: described A hole punch is larger than B hole punch diameter.
