Description

Sheet nail

Technical Field

The utility model belongs to the technical field of the fastener, a piece nail is related to.

Background

The sheet nail, also called melon seed nail, is a metal sheet fastener, usually used on the back plate of photo frame to play a role in fixing, filling into the sheet fixing gun and then ejecting.

FIG. 1 is a schematic view of a conventional sheet nail, generally in the shape of a rectangular sheet, having a head at one end for easy injection. Because the sheet nail is thinner, in order to load the convenience, has set up the breach in the side middle part position of sheet nail, the back is stacked to the multi-disc sheet nail, in the breach rubber coating in order to stick a whole piece of lamination nail together, cut into the piece nail after the segmentation and robbed the use.

The sheet nails are stamped and formed on a whole steel strip raw material by using a stamping machine, and in order to improve the utilization rate of raw materials, the continuous stamping positions need to be as close as possible. During the punching press, because the rubber coating breach of controlling adjacent two slice nails is just right, if the main part of adjacent two slice nails pastes and leans on together, two breachs will enclose to close and be a closed rectangle scope, and the useless piece that leaves over behind this within range punching press is not connected, can drop into stamping die in. Therefore, a certain gap (as shown in fig. 2) is reserved between two adjacent sheet nails in the stamping process of the sheet nails at present, so that waste sheets in the rectangular range after stamping can be connected with a raw material plate and cannot fall into a stamping die.

Above-mentioned traditional way can not take place the condition that the piece falls into in the mould, nevertheless will remain the clearance between piece nail and the piece nail all the time, and the piece nail quantity that single raw and other materials can be punched out has reduced, has produced more waste material, has reduced material utilization.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above problems of the prior sheet nail and provides a sheet nail which can ensure that adjacent sheet nails are arranged without gaps during stamping processing.

The purpose of the utility model can be realized by the following technical proposal:

a sheet nail comprises a sheet body, wherein the head of the body is provided with a nail head, and the sheet nail is characterized in that two side edges of the body are respectively provided with a gluing notch and a protruding part, the number of the protruding parts is one, and the gluing notch and the protruding part on the same side are connected and alternately arranged.

In the above sheet nail, the two glue coating notches are respectively arranged on two sides of the corresponding protruding part.

In the sheet nail, the glue coating notch is one and is positioned at one end of the corresponding convex part close to the nail head.

In the above nail, the glue coating notch is one and is located at one end of the corresponding lug boss close to the tail of the body

In the above sheet nail, the two side edges of the body are symmetrical.

In the above sheet nail, two oblique edges of the nail head are butted with the outer side edges of the corresponding side convex parts.

In the sheet nail, the two oblique edges of the nail head are in butt joint with the bottom edge of the gluing notch on the corresponding side.

Compared with the prior art, the utility model provides a piece nail can not produce the small waste material that drops in the course of working, can zero clearance arrange during the punching press, improves material utilization.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Example 1

As shown in fig. 3, the sheet nail in this embodiment includes a sheet body 1, and the main body of the body 1 is rectangular, and one end of the body has a triangular head 2. The two sides of the body 1 are provided with two gluing notches 3 and two protruding parts 4, the number of the protruding parts 4 on one side is one, in the embodiment, the number of the gluing notches 3 on one side is two, the gluing notches 3 and the protruding parts 4 on the same side are respectively positioned on two sides of the protruding parts 4 on the corresponding side, the gluing notches 3 and the protruding parts 4 on the same side are connected and alternately arranged, and the protruding parts 4 and the gluing notches 3 form steps at the butt joint. The utility model provides a boss 4 and rubber coating breach 3 are according to their respective outside limit corresponding position and decide.

Two bevel edges 5 of the nail head 2 are in butt joint with the bottom edge of the gluing notch 3 of the corresponding side close to the nail head 2, and the left side and the right side of the body 1 are symmetrically identical. Gluing breach 3 is used for the usefulness of paining glue for the later stage, and glue is no longer than 4 outside limits of bellying position, and the gluing breach 3 of homonymy is located body 1's both ends, carries out the adhesion simultaneously with body 1's both ends, and the adhesion is firm.

As shown in fig. 4 and 5, during the punching process, the side edges of the protruding portions 4 of two adjacent sheet nails can be butted, and more products can be arranged and processed in the transverse direction on the raw material plate with the same length. After the processing is finished, the waste material plate 6 can be integrally connected, and no small waste material falls.
