Abstract

The utility model belongs to the field of punching moulds, in particular to a punching module for stator and rotor iron cores of a disc type speed regulating motor used on a XDS-model vacuum pump. The punching module aims to solve the problems that the prior punching module is more complicated and includes a workpiece (a convex mould and a concave mould), a positioning part, a stripping part and an assembly part; the fixation method of the convex mould is more complicated and generally adopts the methods such as low-melting-point alloy pouring, epoxy resin pouring and the like; the punching speed is slower; the clearance between the common convex mould and the concave mould is 0.05 to 0.07; the punching burr is large; the sheet punching quality is bad; and the stacking factor of the stator and the rotor is 0.92 to 0.93; and generally, duplex punching mould is adopted firstly, blanking is carried out secondly and then slotting is carried out. The punching module for the stator and rotor iron cores of a disc type braking motor includes a convex mould and a concave mould; a punching head plywood and a knockout plate have simple structures; the clearance between the convex mould and the concave mould is 0.03 to 0.05; the clearance precision is high; the stacking factor of the stator and the rotor is 0.95, and the sheet punching quality is good. The pouching mould has the advantages of convenient installation, simple structure, integrated blanking and punching, and high efficiency.

Description

XDS type vavuum pump disc type buncher stator-rotor iron core punching out mould

Technical field

The utility model belongs to dash rolls up mould applications, particularly a kind of XDS type vavuum pump disc type buncher stator-rotor iron core.

Background technology

Former punch die is applicable on the common punch press and uses that comparatively complexity is divided into work package (punch, die), keeper, takes off materials and parts, assembly parts.The punch fixing means is comparatively complicated, generally adopts methods such as low-melting alloy cast, poured with epoxy resin.Stamping-out speed is slower, and common punch, die gap are at 0.05-0.07, and be big towards the frizzle thorn, the punching poor quality, and the rotor stacking factor is 0.92-0.93mm.

The utility model content

XDS type vavuum pump is applicable to the full-automatic Punching and rolling machine of Switzerland's import with disc type buncher stator-rotor iron core punching out mould, adopts takeup type to dash volume, and reel in punching limit in limit aborning.Punch die is divided into punch, die, and drift clamping plate, knockout plate are simple in structure, punch, die gap 0.03-0.05, and the gap precision height, the rotor stacking factor is high by 0.95, has reduced iron loss, and the punching quality is good.This mould is easy for installation, and blanking and stamping-out accomplish without any letup, the efficient height.Punch, die adopt high rigidity, high strength, and the W18Cr4V of high-wearing feature and fatigue capability makes.Drift clamping plate, knockout plate are made with Cr12.Mould interchangeability is good, and it is convenient to install and repair.The parallel processing with die of punch, die manufacturing cycle is short.When punch weares and teares, can only make punch, die can continue to use, and punch can not scrapped.

Description of drawings

Fig. 1 is an XDS type vavuum pump disc type buncher stator-rotor iron core punching out mould structure schematic diagram.

(1) is punch among the figure, and (2) are the drift clamping plate, and (3) are die, and (4) are knockout plate.

The specific embodiment

As shown in Figure 1, punch (1) is put into drift clamping plate (2), clamp with bolting, then with die (3), knockout plate on the pad (4), be fixed on the knife rest bottom with straight pin, the clamping plate that will have drift are fixed by bolts to knife rest top. when stamping-out, punch enters in the die, the material of institute's stamping-out directly falls from feeding plate simultaneously, has improved efficiency.

The utility model is used for the transformer fan of the usefulness of the used cooling blower of transformer cooler, and the noise of the on-stream generation of blower fan usually becomes influences the misfortune of workers ' health and interference environment source.Particularly be close to the blower fan in living area, the air power noise of its air inlet and the radiation of air outlet institute, the principal element of contaminated environment forms public hazards especially, is that Industry Branch is administered one of main object of noise pollution in recent years.In order to reduce the pollution because of the NOISE ON ENVIRONMENT of transformer, adopting the low noise blower fan is the main path that reduces transformer noise.

Claims

1, XDS type vavuum pump disc type buncher stator-rotor iron core punching out mould, it is characterized in that: punch (1) is put into drift clamping plate (2), clamp with bolting, then with die (3), knockout plate on the pad (4), be fixed on the knife rest bottom with straight pin, the clamping plate that will have drift are fixed by bolts to knife rest top.

2, XDS type vavuum pump according to claim 1 disc type buncher stator-rotor iron core punching out mould, it is characterized in that: punch (1), die (3) adopt high rigidity, high strength, and the W18Cr4V material of high-wearing feature is made.
