Abstract

The utility model aims at providing a rebound-prevention device of punching waste and a rebound-prevention system of the punching waste. The rebound-prevention device of the punching waste comprises a base portion and a cylinder body connected with the base portion. A plurality of seams which extend in the axial direction are formed in the cylinder body at intervals, and the cylinder body is divided into a plurality of opening-closing cylinder pieces by the seams. Clamping hooks which protruding inwards in the radial direction are arranged at the top ends of the cylinder pieces, and the outer lateral faces of the clamping hooks are inclined planes. The base portion and the cylinder body are penetrated through the same shaft hole, and a punch waste discharging channel is formed by the shaft hole.

Description

Punched scrap prevent from knock-oning device and punched scrap prevents the rebound system

Technical field

The utility model relates to pressing equipment, relates in particular to punched scrap and prevents the device that knock-ons.

Background technology

Trimming and piercing die class mould, in the punching production process, often can be encountered waste material and not glide, the punched scrap problem on the product profile of knock-oning.Because punched scrap is smaller, be difficult for being found, once occur that this problem will cause product rejection, or even insert and break, this problem is the difficult problem in the punching production process always, is also one of key factor of restriction productive temp.

The utility model content

The purpose of this utility model is to provide a kind of punched scrap prevent from knock-oning device and punched scrap to prevent the rebound system.

Punched scrap of the present utility model prevents the device that knock-ons, it comprises the cylindrical shell of a section and Connection Block section, be formed with isolated many axially extended gaps on cylindrical shell, but described gap is divided into cylindrical shell a plurality of sheets of opening and closing, the top of described cylinder sheet has radially to projecting inward grab, the lateral surface of grab is inclined-plane, and described seat section and described cylindrical shell are run through by same axis hole, and described axis hole forms the punched scrap drain passage.

Described punched scrap prevents the device that knock-ons, and wherein, described cylindrical shell is cylinder.

Punched scrap of the present utility model prevents the rebound system, comprise die plate insert, this die plate insert has plane and the nib of putting plate, be characterized in, also comprise that described punched scrap prevents the device that knock-ons, below nib, this die plate insert has accommodating hole, the described punched scrap device that prevents from knock-oning is placed in accommodating hole, described nib and described punched scrap drain passage are coaxially set, described grab protrudes with respect to described nib Geng Yaoxiang center, and the described cylinder sheet of described cylindrical shell can open to receive the piercing punch insertion.

Characteristics of the present utility model and advantage will be described in detail in aftermentioned embodiment.

The accompanying drawing explanation

Fig. 1 is that punched scrap prevent from the knock-oning axle of device is surveyed view.

Fig. 2 is punched scrap prevent from the knock-oning top view of device.

Fig. 3 is punched scrap prevent from the knock-oning front view of device.

Fig. 4 is the operation principle schematic diagram that punched scrap prevents the system of knock-oning.

The specific embodiment

As shown in Figure 1 to Figure 3, the punched scrap device that prevents from knock-oning comprises the cylindrical shell 10 of a section 2 and Connection Block section 2, be formed with isolated many axially extended gaps 11 on cylindrical shell 10, totally four, gap 11, but cylindrical shell 10 is divided into to a plurality of sheets 12 of opening and closing, the top of each sheet 12 has radially to projecting inward grab 13, and the lateral surface of grab 13 is inclined-plane, seat section 2 and cylindrical shell 10 are run through by same axis hole 20, and axis hole 20 forms the punched scrap drain passage.In embodiment as shown in the figure, cylindrical shell 10 is cylinder.

As shown in Figure 4, the punched scrap device that prevents from knock-oning is placed to the punched scrap formed in an embodiment of the present utility model in pressing equipment and prevents the rebound system, it comprises die plate insert 3, die plate insert 3 has plane and the nib (part that piercing punch 5 inserts) of putting plate 4, also comprise that punched scrap as shown in Figure 1 to Figure 3 prevents the device that knock-ons, below nib, die plate insert has accommodating hole 40, the punched scrap device that prevents from knock-oning is placed in accommodating hole 40, nib and punched scrap drain passage are coaxially set, grab 13 protrudes with respect to nib Geng Yaoxiang center, and the cylinder sheet 12 of cylindrical shell 10 can open to receive piercing punch 5 and insert.

After punching press finishes, with the piercing punch 5 of liftout, punched scrap 6 is headed into to the punched scrap drain passage, punched scrap prevent from the knock-oning cylinder sheet 12 of device opens the also piercing punch 5 of clamping band liftout.Punching press finishes piercing punch 5 backhauls, and punched scrap 6 is just just stayed and prevented from knock-oning the device the inside by grab 13.

Previous embodiment has solved the problem of punched scrap 6 rebounds substantially, for improving stamping production efficiency and stability, very large help is arranged, and can promote the use of in the mould of punching.Therefore the utility model is not limited in embodiment as shown in the figure, and for example cylindrical shell 10 can be with the change in shape of punching, and is not limited to circle.Cylindrical shell 10 also is not limited to be separated into four cylinder sheets, can also be more than two or two.

Claims
