Description

A kind of magnet pay-off

Technical field

The utility model relates to a kind of pay-off that is used on the automobile longitudinal girder numerical control punching production line.

Background technology

Automobile longitudinal girder numerical control punching line with hydraulic pressure as active force, be mainly used in at the bottom of the U type longeron abdomen after the moulding or flat board carry out punching, it is widely used in automobile manufacture industry.This equipment is when work, because workpiece is longer, prior art adopts a plurality of clamps to clamp workpiece, carries out feeding by clamp, such feeder structure complexity, it is big to take up room, manufacturing cost is higher, and a plurality of grip(per) feeds need be dodged, efficient is compared low, is difficult for realizing high-speed cruising.

Summary of the invention

The purpose of this utility model is to provide a kind of technical scheme of magnet pay-off, makes that it is simple in structure, feeding is convenient, can realize high-speed cruising.

The purpose of this utility model is achieved in that a kind of magnet pay-off, comprise two mutual parallel and horizontally disposed line slideways, be respectively arranged with slide block on the line slideway, slide block is fixed on horizontally disposed base plate downside, also be fixed with four axis of guides on the base plate perpendicular to base plate, the rectangular distribution of the axis of guide, one lifting support is set on four axis of guides through its four jiaos linear bearings that are provided with, the top of the axis of guide is provided with upper limit mechanism, the lifting support upside is fixed with electromagnet, the base plate downside is provided with the cylinder perpendicular to base plate, the piston rod of described cylinder is upward through base plate and is connected with lifting support, also is provided with the compression spring that floats between lifting support and the base plate.

In the utility model when work, be pull-in on the electromagnet upper surface by electromagnet with automobile longitudinal girder to be processed, whole device can be on two parallel line slideways moving linearly, lifting support can move up and down on the axis of guide by linear bearing; Before the use, do not have pressure in the cylinder, electromagnet is positioned at a certain height under the active force of compression spring that floats; After the air inlet of cylinder top, electromagnet overcomes spring force and moves downward lower dead center, after beam to be processed is also located to the electromagnet top by handling, the cylinder exhaust, electromagnet moves upward, because have the effect of spring force this moment, electromagnet can be realized fluctuating, thus the vibration of longeron when adapting to the unevenness of longeron and punching.The active clamp of the driven by servomotor by longeron end peripheral hardware to be processed promotes longeron and electromagnet pay-off and moves on line slideway, realizes feeding.As seen, the utility model feeding is steady, convenient, and it is simple in structure, can not cause the problem of dodging of grip(per) feed, can realize the production line high-speed operation.The utility model also not only is confined to the production of automobile longitudinal girder, also can be applied to carry out feeding on the automatic assembly lines such as other sheet metals, section bar.

Cause linear bearing bump upper limit mechanism when compressing spring reset, can between upper limit mechanism and linear bearing, be provided with cushion blocking for avoiding floating.

Fig. 3 is the utility model stereogram;

Wherein, 1 active clamp, 2 upper limit mechanisms, 3 cushion blockings, 4 float compresses springs, 5 piston rods, 6 cylinders, 7 slide blocks, 8 axis of guides, 9 line slideways, 10 linear bearings, 11 lifting supports, 12 electromagnet, 13 to be processed, 14 base plates.

The specific embodiment

As Fig. 1,2, shown in 3, a kind of magnet pay-off, comprise two mutual parallel and horizontally disposed line slideways 9, be respectively arranged with slide block 7 on the line slideway 9, slide block 7 is fixed on horizontally disposed base plate 14 downsides, also be fixed with four axis of guides 8 on the base plate 14 perpendicular to base plate 14, the axis of guide 8 rectangular distributions, one lifting support 11 is set on four axis of guides 8 through its four jiaos linear bearings 10 that are provided with, the top of the axis of guide 8 is provided with upper limit mechanism 2, upper limit mechanism 2 can adopt limited block or limiting plate etc., be fixed on the end of the axis of guide 8 by screw, lifting support 11 upsides are fixed with electromagnet 12, and base plate 14 downsides are provided with the cylinder 6 perpendicular to base plate 14, the piston rod 5 of cylinder 6 is upward through base plate 14 and is connected with lifting support 11, also is provided with the compression spring 4 that floats between lifting support 11 and the base plate 14.Cause linear bearing 10 bump upper limit mechanisms 2 when compression spring 4 resets for avoiding floating, can be provided with cushion blocking 3 between upper limit mechanism 2 and linear bearing 10, this cushion blocking 3 can adopt polyurethane material to make, and can have good absorbing effect.

During the utility model work, be pull-in on electromagnet 12 upper surfaces by electromagnet 12 with to be processed 13, on the automobile longitudinal girder production line, this to be processed 13 is flat board or U type beam; Slide block 7 is moving linearly on two parallel line slideways 9, and lifting support 11 can move up and down on the axis of guide 8 by linear bearing 10; Before the use, do not have pressure in the cylinder 6, electromagnet 12 is positioned at a certain height under the active force of compression spring 4 that floats; After the cylinder 6 top air inlets, electromagnet 12 overcomes spring force and moves downward lower dead center, when to be processed 13 by handling to electromagnet 12 tops and the location after, cylinder 6 exhausts, electromagnet 12 moves upward, because the effect of spring force is arranged this moment, damage electromagnet 12 in order to prevent too fast and to be processed 13 of electromagnet 12 motion from bumping against, air pressure can not be big, should reduce pressure by pressure-reducing valve, though making electromagnet 12 contact the back with workpiece still has power upwards but is not enough to the jack-up longeron, the inductive switch that be installed on the electromagnet 12 this moment sends signal, electromagnet 12 energising firmly holds longeron, after extremely short time-delay, and the effect of the magnetic valve by letting out the position in having, allow two blow vents of cylinder 6 all communicate with atmosphere, under the effect of spring force, electromagnet 12 can be realized fluctuating like this, thus to be processed 13 vibration when adapting to be processed 13 unevenness and punching.The active clamp 1 of the driven by servomotor by to be processed 13 end peripheral hardware promotes to be processed 13 and electromagnet 12 pay-offs and moves on line slideway 9, realizes steady feeding.
