Abstract

A sucked type loading device comprises a sucking disk and a valve body communicated with the sucking disk through a pipeline; wherein the back end of the valve body is equipped with a handle; the external side of a valve of the valve body is sleeved with a spring; a sealing cushion is provided between the valve and the valve body. As the utility model presses the sucking disk and presses down the valve, a venthole of the valve body is stuffed up by the sealing cushion, which prevents the outer air from flowing into the pipeline and hence a workpiece can be tightly adhered to the sucking disk. When the workpiece is sent to the designated place on a mould and the pressed valve is loosened, the valve takes the sealing cushion away from the stuffed venthole; under the spring action; the outer air flows into the sucking disk through the pipeline; then the workpiece falls down automatically and the loading operation ends up. The utility model has the advantages of simple structure, easy use, safety and reliability; furthermore, the utility model doesn't need power source, can be flexibly used in different occasions and not be limited to the material of the workpiece.

Description

A kind of sucked type material loading instrument

Technical field

The utility model is a kind of material loading instrument, is specifically related to a kind of sucked type material loading instrument that comes mobile thin plate workpiece by the negative pressure that produces between sucker and the workpiece.

Background technology

In medium-sized and small enterprises plate punching production, the most general with the single die tool.The situation that punching (or shaping, bending etc.) behind the first blanking is often arranged.When the second operation work material loading, often adopt manual material loading, with tweezers workpiece is held under the arm into, inefficiency and dangerous; Or adopt electromagnetism material loading instrument, and the efficient height, labour intensity is low, and safety is better.Once pick up many problems, especially thin plate workpiece but exist, if put into mould, the mold damage that is bound to, punch press threaten operator's personal safety, and this is unallowed in punching production.And electromagnetism material loading instrument is subjected to the restriction of workpiece material, can only be used for ferrous meatal.

Summary of the invention

The purpose of this utility model provides a kind of propulsion source that do not need, and just can make things convenient for, the failure-free holding workpiece, finishes the sucked type material loading instrument of material loading action.

For achieving the above object, the technical solution adopted in the utility model is: comprise sucker and the valve body that is connected with sucker by conduit, rear end at valve body is provided with handle, and the valve outside of this valve body is set with spring, is provided with packing seal between valve and the valve body.

Sucker of the present utility model is connected with conduit with tapered sleeve by the screw thread tapered plug, and this screw thread tapered plug and tapered sleeve are for being threaded; Also be provided with the pin of ascending the throne that is used for the limiter valve shift position that is connected with valve in the valve body.

Because the utility model blocks the sealed pad of air extractor vent of valve body by extruding sucker and following pressure valve, does not allow outside air enter in the conduit, workpiece and sucker tightly stick together.When workpiece being delivered on the mould assigned address, unclamp the valve of pinning, under the effect of spring, the valve band packing seal and is left the air extractor vent that is blocked.Outside air enters in the sucker by conduit, and workpiece just falls automatically, finishes the material loading action.The utility model is not only simple in structure, easy to use, and is safe and reliable, do not need propulsion source, and various occasions can both be used flexibly, and is not subjected to the restriction of workpiece material.

Description of drawings

Fig. 1 is an integral structure scheme drawing of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are described in further detail.

Referring to Fig. 1, the utility model comprises sucker 1 and the valve body 5 that is connected with sucker 1 by conduit 4, sucker 1 is connected with conduit 4 with tapered sleeve 3 by screw thread tapered plug 2, this screw thread tapered plug 2 and tapered sleeve 3 are for being threaded, be provided with handle 10 in the rear end of valve body 5, valve 7 outsides of this valve body 5 are set with spring 9, also are provided with the pin 8 of ascending the throne that is used for limiter valve 7 shift positions that is connected with valve in the valve body 5, are provided with packing seal 6 between valve 7 and the valve body 5.

Hold handle 10 during work and sucker 1 is placed on will obtains on the work blank, firmly one press gently downwards a little, the air between workpiece and the sucker 1 is extruded, this moment, sucker 1 launched also to be flattened on the workpiece.With pressure valve under the forefinger 7, the sealed pad 6 of air extractor vent of valve body 5 is blocked then, do not allowed outside air enter in the conduit 4.When upwards mentioning sucker 1, under the workpiece action of gravity, the air chamber between workpiece and the sucker 1 will increase to some extent.At this moment, the air in conduit 4 apertures will expand and produce negative pressure, and under the atmospheric effect in the external world, workpiece and sucker 1 tightly stick together.When workpiece being delivered on the mould assigned address, unclamp the forefinger of pinning valve 7, under the effect of spring 9, valve 7 leaves the air extractor vent that is blocked with packing seal 6.Outside air enters in the sucker 1 by conduit 4, and this moment, inner and outer air pressure equated, by gravity, and workpiece just falls automatically, finishes the material loading action.
