The tooling is characterized in that the chuck (7) is an electric-control permanent-magnetic chuck. The tooling has the advantages of low cost, safety and reliability, and strong chuck clamping force.
Description
Technical field
The utility model belongs to mechanical field, a kind of specifically electric-controlled permanent magnetic chuck formula terminal-collecting machine of multiple position press quick mold change systems.
Background technology
In actual production, metal forming machinery all needs frequently to carry workpiece.For multiple position press, be furnished with terminal-collecting machine on the pay-off of quick mold change systems, it mainly acts on is to draw workpiece and finish the space of workpiece in punching course by the motion that promotes crossbeam and send crossbeam to and move.The operation principle of terminal-collecting machine is: be adsorbed on surface of the work, carry workpiece by the high flexibility special fixture by sucker, the automation end that has formed workpiece by proximity transducer, programmable logic controller (PLC) etc. picks up and transports system, and the end when having guaranteed the multiple position press operate as normal picks up and drawing velocity.
The sucker of present terminal-collecting machine is vacuum cup, is to form negative pressure in rubber cup or flexible plastic bowl, relies on the pressure differential of atmosphere workpiece is sucked.Its shortcoming is that vavuum pump and corollary equipment cost thereof are higher; The sealing of sucker is low, poor reliability; And the pretightening force of single sucker is limited, needs a plurality of suckers and works simultaneously, and is wayward, also increased the probability that breaks down.
Summary of the invention
For the vacuum cup poor reliability that overcomes existing terminal-collecting machine, wayward, the deficiency that easily breaks down, the utility model provides a kind of electric-controlled permanent magnetic chuck formula terminal-collecting machine of multiple position press quick mold change systems, and that this permanent magnetic chuck formula terminal-collecting machine has is safe and reliable, the sucker clamping force big, can realize the characteristics of control automatically.
The technical solution of the utility model is: a kind of electric-controlled permanent magnetic chuck formula terminal-collecting machine of multiple position press quick mold change systems, comprise the sucker of steering connections and end thereof, and described sucker is an electric-controlled permanent magnetic chuck.
Described sucker is made up of magnetic pole piece, housing, alnico magnet, coil, epoxy resin, rubidium iron boron permanent magnet, the enclosure interior lower floor of upper opening is provided with the alnico magnet that two sides are twined by coil, the upper strata is provided with the magnetic pole piece that two sides are surrounded by rubidium iron boron permanent magnet, and rubidium iron boron permanent magnet and coil outside are filled with epoxy resin.
The utlity model has following beneficial effect: owing to take such scheme, this terminal-collecting machine sucker changes electric-controlled permanent magnetic chuck into by vacuum cup in the past, by feeding direct current, magnetic pole is magnetized, the workpiece that is positioned over chuck surface is produced magnetic force, workpiece is clamped condition; When feeding the opposite direct current of direction, workpiece is unclamped in the magnetic pole demagnetization.This permanent magnetic chuck control time is short, can realize quick clamping, unclamp fast, and performance is safe and reliable, clamping force is big, can realize automatic control, satisfies the requirement of multiple position press quick mold change systems fully.

The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in Fig. 1-5, a kind of electric-controlled permanent magnetic chuck formula terminal-collecting machine of multiple position press quick mold change systems, comprise feeding crossbeam 1, binding clasp 2, support bar 3, secondary bar 4, mobile jib 5, steering connections 6, sucker 7, be fixed with two secondary bars 4 on the described mobile jib 5, connect two support bars 3 again respectively on each secondary bar 4, the end of support bar 3 connects sucker 7 by steering connections 6, described steering connections 6 is flexible joint, once only adjust an axle, and do not destroy other each direction, there is sucker 7 steering connections 6 ends, described sucker 7 is an electric-controlled permanent magnetic chuck, by magnetic pole piece 8, housing 9, alnico magnet 10, coil 11, epoxy resin 12, rubidium iron boron permanent magnet 13 is formed, described housing 9 upper openings, its inside is divided into two-layer up and down, lower floor is provided with the alnico magnet 10 that two sides are twined by coil 11, the upper strata is provided with the magnetic pole piece 8 that two sides are surrounded by rubidium iron boron permanent magnet 13, gap between rubidium iron boron permanent magnet 13 and coil 11 outsides and the housing 9 is filled with epoxy resin 12, during installation, housing 9 openings one side is to workpiece, and the magnetic force that magnetic pole piece 8 is produced can firmly hold workpiece.Because housing 9 inside are magnetic material, make sucker 7 inside become a magnetic pole, can make it produce magnetic force by feeding electric current.
By Figure 6 and Figure 7, when magnetic pole feeds direct current, sense of current left side coil is counterclockwise, when the right side coil is clockwise, the magnetic line of force produces magnetic force by chuck surface to the workpiece that is positioned over chuck surface, is discharged into working surface, externally is characterized by and magnetizes, promptly workpiece is clamp position, this moment, magnetic pole was in strong magnetic force state; When magnetic pole feeds the opposite direct current of direction, sense of current left side coil is clockwise, when the right side coil is counterclockwise, the magnetic line of force does not produce magnetic force by sucker inside to the workpiece that is positioned over chuck surface, make permanent magnetic field in inner self balance of magnetic pole, externally be characterized by demagnetization, promptly workpiece be releasing orientation, this moment, magnetic pole was in non-magnetic force state.From the above, when magnetic pole is worked, only need the control sense of current, control is no more than 1 second the working time, clamps with the efficient of unclamping very highly, and clamping force is big, the clamping force of its single magnetic pole can reach 150N/cm2, satisfy the requirement of multiple position press mold changing systems fully, utilize the practicable microcomputer Long-distance Control of PLC interface simultaneously, improve automaticity.
The utility model replaces existing vacuum cup with electric-controlled permanent magnetic chuck, and existing terminal-collecting machine mechanism and electric-controlled permanent magnetic chuck are combined, and realizes multiple position press automation requirement; Realize that magnechuck and permanent magnetic chuck combine, the quick mold change systems terminal-collecting machine that the electric control permanent magnet clamping mode is applied to large-scale multiple position press is drawn on the workpiece, permanent magnetic circuit technology and the pulsed discharge technology of magnetizing are combined, electricity is as the switch of magnetic, only need be in several seconds of switch supply of electrical energy, and do not have mechanical moving element, and simple to operate quick, safe and reliable, can realize automatic control.
