Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an air feeding device for press-cutting material according to the present invention, which is particularly applicable to scraps, screws, bolts, washers, and small electric parts when metal is processed by high-speed automatic pressing. It is suitable for delivering a cutting material composed of small products, etc. by air.

[Prior Art] Conventionally, in this type of device, it is necessary to attach the upper edge of the hopper to the bottom surface of the bolster or the bed with bolts in order to lower the cutting material housed in the hopper satisfactorily by the vibration of the cutting operation of the press. It has the drawback of being inconvenient to put on and take off. Especially, when it is attached to the bottom surface of the bolster, it is often complicated when the mold is replaced together with the bolster.

[Problems to be Solved by the Invention] This invention is an air for press-cutting material that enables the upper edge of the hopper to be brought into close contact with or separated from the lower surface of the bolster or bed very easily as necessary while maintaining good functions. A delivery device is provided.

[Means for Solving the Problems] The present invention provides a hopper that receives a cutting material that is cut by a press and falls, and a body to which a lower end portion of the hopper is attached and the cutting material that comes out of the hopper is delivered by air. A spring member for supporting the main body, and three or more screw members that are rotatably screwed to the main body to raise and lower the main body, and adjust the screw members so that the upper end edge of the hopper is adjusted. (EN) Provided is an air feeding device for press-cutting material, which can be brought into close contact with or separated from the lower surface of a bolster or a bed of a press.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

In one embodiment of the present invention shown in FIGS. 1 and 2, 1
Reference numeral 0 indicates an air feeding device for press-cutting material according to the present invention as a whole. 12 is a hopper. Reference numeral 13 is a main body to which the lower end of this hopper is fixed, and a flow path 15 is formed for delivering a cutting material made of a scrap or a product cut by a press falling from the hopper 12 by an air flow. Reference numeral 16 is an inflow port for allowing air to flow into the flow path 15 from a compressed air source (not shown) through a hose. 17
Is a delivery port for delivering the cutting material by the air flowing in from this inflow port, and is connected to a hose (not shown). 18 is a recess formed in the four corners of the main body 13 from above and below,
Reference numeral 0 denotes a screw member that is screwed into the female screw portion 21 formed in the portion between the recesses and extends slightly longer than the lower surface of the main body 13. Generally, three or more screw members are required. 23
Is a support member having a lower surface to which a spring member 25 made of rubber having a thickness of, for example, about 0.5 to 2.0 mm is attached. The lower ends of the screw members 20 are rotatably abutted and supported. It has become. A recess may be formed on the upper surface of the support member so that the lower end of the screw member 20 can be rotatably inserted.

Reference numeral 30 is a bed of the press, 31 is a bolster to which a mold 32 is attached, and 33 is a step portion formed on the bed 30.

In the structure as described above, the screw member 20 is adjusted and used so that the upper edge of the hopper 12 comes into close contact with the step 33 on the lower surface of the bed 30.
In this state, the cutting material discharged from the press enters the hopper 12. The vibration due to the cutting operation of the press is transmitted to the hopper 12 and the main body 13 as it is because of the spring member 25, and the cutting material descends well and enters the flow path 15 of the main body 13 and is delivered by air. Bed 30 hopper 12
When it is necessary to separate the screw member 20, the screw member 20 can be loosened to easily perform the operation. In this device, the hopper 1
In some cases, the upper edge of 2 may be brought into close contact with the lower surface of the bolster 31. A metal spring may be used as the spring member 25.

[Advantage of the Invention] Since the present invention is configured as described above, the upper end edge of the hopper 12 is closely contacted with the bottom surface of the bed 30 or the bolster 31 while maintaining a good function of the press cutting material as an air feeding device. It has the effect that it can be moved and released very easily.

[Brief description of drawings]

FIG. 1 is a front view showing an embodiment of the present invention, and FIG. 2 is a plan view thereof. 10 is an air feeding device for press cutting material, 12 is a hopper,
Reference numeral 13 is a main body, 15 is a flow path, 20 is a screw member, 21 is a female screw portion, 23 is a support member, 25 is a spring member, 30 is a bed, and 31 is a bolster.
