Abstract
The utility model discloses a material guiding and pushing device for an automatic iron core stacking progressive die, relating to mechanical equipment. The material guiding and pushing device comprises symmetrical material pushing pins. Stepped through holes are arranged on a lower die holder, and the lower parts of the material pushing pins are sheathed in the stepped through holes and can slide relative to the stepped through holes. Through holes are arranged on a die, and the upper parts of the material pushing pins are sheathed in the through holes and can slide relative to the through holes. The upper end faces of the material pushing pins are higher than the upper surface of the die, and the material pushing pins are provided with return springs at parts sheathed in the stepped through holes. The upper surface of the die is oppositely provided with two material guiding plates, and two opposite side faces of the material guiding plates are provided with extended-outwards humps along a direction vertical to the side faces. The material guiding and pushing device has high guiding and positioning precision to strip materials and can prevent the strip materials from jumping upwards, the strip materials and the die can keep a certain gap, a guide pin is favorable for correcting the strip materials, and the material guiding and pushing device is very practical.
Description
Technical field
The utility model relates to a kind of plant equipment, relates in particular to a kind of guide and Lifting Device that is used for automatic overlapping and assembling progressive die unshakable in one's determination.
Background technology
In motor, the electric equipment products, silicon steel sheet closed assembly iron core is one of important components, and iron core weight accounts for the 25%-30% of product weight, and quality unshakable in one's determination has direct influence to properties of product.Iron core generally is to be processed by the silicon steel sheet of the high and low loss of permeability, for reducing loss, requires iron core to be divided into thin slice vertically, and thickness is at 0.35mm or 0.5mm, and therefore an iron core can be made up of tens as many as hundreds of sheet silicon steel sheets.Therefore the manufacturing batch of iron-core lamination is very big.The processing method operation of using in the past unshakable in one's determination is many, and manual operations is many, and production efficiency is low, and labor strength is big, the closed assembly difficult quality guarantee.Along with the development of industrial technology, be employed in the progressive die production on the high velocity ram machine, tend to high-speed automated production.Closed assembly unshakable in one's determination is progressively by the automatic overlapping and assembling transition of traditional processing method to iron core.Automatic overlapping and assembling progressive die technology unshakable in one's determination has begun to apply in industrial advanced country in the later stage seventies 20th century.The automatic overlapping and assembling technology is applicable to that in the motor, electric equipment products of production in enormous quantities, the stamping-out speed that is suitable for can reach 140-350 time/min, and a sharpening life-span reaches more than 1,000,000 times, and mould entire life can be up to more than the TFlops.The automatic overlapping and assembling technology can be used for motor stator and rotor and mountain shaped iron core etc., superimposed Li Keda 75N-120N.But when using existing automatic overlapping and assembling progressive die unshakable in one's determination, the billot of band processing transports when advancing, and goes up easily and jumps; And the guide-localization precision of billot is low; Influence the efficient and the precision of product processing, existing in addition automatic overlapping and assembling progressive die unshakable in one's determination is not provided with the float-up device of billot, after billot is gone out convexity; Usually can be fitted in the die upper surface, make and send to and can't carry out.
Summary of the invention
Problem to above-mentioned prior art existence; The utility model provides a kind of guide and Lifting Device that is used for automatic overlapping and assembling progressive die unshakable in one's determination; Guiding and positioning accuracy to billot are high, prevent to jump on the billot, and can make billot and die keep certain interval; Help pilot pin to the billot correcting, very practical.
The technical scheme of the utility model is: a kind of guide and Lifting Device that is used for automatic overlapping and assembling progressive die unshakable in one's determination, comprise symmetrically arranged jigger pin, and have ladder hole on the die shoe; The jigger pin bottom is socketed in this ladder hole, and ladder hole slides relatively, has through hole on the die; Jigger pin top is socketed in this through hole; And through hole slides relatively, and the upper surface of jigger pin is higher than the upper surface of die, and the part that jigger pin is socketed in the ladder hole is provided with back-moving spring; The die upper surface is relatively set with two stock guides, and stock guide edge, two sides in opposite directions is provided with outward extending convexity with the direction of lateral vertical.
As preferably, said jigger pin adopts steel alloy to process.
As preferably, be provided with backing plate between die and the die shoe.
As preferably, said jigger pin eminence die upper surface 2-3mm.
As preferably, said jigger pin upper surface is set to hemisphere face, has oiling groove on this hemisphere face.
The beneficial effect of the utility model is: jigger pin of the utility model and back-moving spring can let billot keep certain interval after the punching press and between the die, help pilot pin to the billot correcting, and sending to smoothly of billot carried out, and have improved production efficiency.Stock guide has guaranteed sending to of billot and positioning accuracy, and the convexity on the stock guide can effectively prevent to jump on the billot, guarantees the efficient and the precision of product processing, and is very practical.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As a kind of embodiment of the utility model, as shown in Figure 1, a kind of guide and Lifting Device that is used for automatic overlapping and assembling progressive die unshakable in one's determination; Comprise symmetrically arranged jigger pin 6, in the present embodiment, as preferably; Said jigger pin 6 adopts steel alloy to process, and hardness is preferably 56-68HRC.Have ladder hole on the die shoe 1, jigger pin 6 bottoms are socketed in this ladder hole, and ladder hole slides relatively; Have through hole on the die 3, jigger pin 6 tops are socketed in this through hole, and through hole slides relatively; The upper surface of jigger pin 6 is higher than the upper surface of die 3; In the present embodiment, as preferably, said jigger pin 6 eminence dies 3 upper surface 2-3mm.Said jigger pin 6 upper surfaces are set to hemisphere face, have oiling groove on this hemisphere face, and are convenient lubricated for targeting part, reduce wear, and guarantee guiding accuracy.
