Abstract

The utility model provides a hand-operated gripping device for feeding and discharging small stamping workpieces. The hand-operated gripping device comprises an iron core and a coil wound on the iron core, wherein a soft iron housing is arranged outside the coil and the iron core and connected with an insulation handle, and both ends of the coil are provided with leads which penetrate through the handle and are finally connected with a power. A press-button switch is arranged at the tail end of the handle. When the press-button switch is turned on, the coil and the iron core form an electromagnetic field, and one end of the iron core becomes the N/S pole of the electromagnet. Both ends of the soft iron housing under the magnetic field become electromagnets with N/S poles, so that a stamping workpiece can be attracted. Otherwise, the stamping workpiece falls naturally. When the weight of a stamping workpiece changes, the stamping workpiece can be lifted only by increasing or decreasing the current, which is simply structured, economical and practical.

Description

Mini-type punching spare feeding material returned hand clamp device

Technical field

The utility model relates to the electromagnet application technology, relates in particular to a kind of mini-type punching spare feeding material returned hand clamp device that is used in.

Background technology

The implication of electromagnet: i.e. energising produces a kind of device of magnetic.The conductive winding that is complementary with its power is twined in outside at iron core, and this alive coil has certain magnetic as magnet, thereby is defined as electromagnet.

The operation principle of electromagnet: electromagnet mainly is made up of coil, iron core and armature three parts.Coil is on iron core, and behind coil electricity, iron core and armature are magnetized, and becomes opposite polarity two blocks of magnet, produces electromagnetic attraction between them.When the electric current in the coil during less than certain certain value or interruption of power supply, magnetic is accomplished and is disappeared.

At present, what market left-hand seat folder instrument adopted is complete manually permanent magnet device, and the magnetic force size is unadjustable, and the weight of the feeding material returned is limited to, and the stamping parts that differs to weight specification need be equipped with different hand folder instruments, and it is required to satisfy different operating modes; The reason that can not disappear because of magnetic field in the time of the material returned causes the stamping parts difficult drop-off, material returned difficulty, and operation is inconvenience extremely, has influenced production work efficient widely.

Summary of the invention

To above defective, the utility model provide a kind of feeding, the material returned convenient, can satisfy that different operating modes are required, simple to operate, the electromagnet hand clamp device of high efficiency.

For realizing above-mentioned purpose, the utility model adopts following technical scheme, mini-type punching spare feeding material returned hand clamp device; Comprise coil, iron core; Coil is wrapped on the iron core, it is characterized in that: be provided with the soft iron shell at coil and iron core outside, the soft iron shell is connected with handle; The two ends of coil are provided with lead, and lead passes the inside of handle and is provided with switch at the end of handle, is connected to power supply at last.

Improvement to such scheme is: described handle is an insulated handle.

Improvement to such scheme is: described switch is a push-button switch.

Beneficial effect:

When the utility model started the power supply rotary switch, coil and iron core formed electromagnetic field, and iron core one end becomes N, the S level of electromagnet; The two ends of soft iron shell also become the magnet with N, S level respectively under the effect in magnetic field; Thereby can suck up stamping parts, when unclamping press button, whole circuit cuts off the power supply at once; The magnetic field stamping parts that disappears immediately comes off the problem of stamping parts difficult drop-off when having solved the material returned naturally under the effect of gravity; When the stamping parts weight specification changes, just can lifting weight stamping parts diversified in specifications as long as increase or reduce electric current, thus it is required to satisfy different operating modes, and simple in structure economical and practical.

Description of drawings

Fig. 1 is the assembly of devices figure of the utility model.

Among the figure 1, the soft iron shell, 2, iron core, 3, coil, 4, handle, 5, push-button switch 6, power supply.

The specific embodiment

As shown in Figure 1, comprise coil 3, iron core 2, coil 3 is wrapped on the iron core 2, is provided with soft iron shell 1 in coil 3 and iron core 2 outsides, and soft iron shell 1 is connected with handle 4; The two ends of coil 3 are provided with lead, and lead passes the inside of handle 4 and is provided with push-button switch 5 at the end of handle 4, is connected to power supply 6 at last.

Handle 4 is an insulated handle.

Push-button switch 5 during use, energising in the coil 3, and iron core 2 just has magnetic, and iron core 2 is 1 magnetization of soft iron shell; Thereby pick up stamping parts, when turning off push-button switch 5 coil 3 outages; The magnetic pop-off of soft iron shell 1, and then return metal works, reach the convenience of the feeding and the material returned; When the stamping parts weight specification changes, just can lifting weight stamping parts diversified in specifications as long as increase or reduce electric current through rotary switch, thus it is required to satisfy different operating modes.
