Abstract
The invention discloses a cutting and burr-free blanking process for a hardware material belt, which comprises the following steps of firstly, presetting a cutting line on the surface of a product; secondly, respectively punching an upper pressing line and a lower pressing line on two sides of a cutting line of the product; and thirdly, the punching die is half-cut upwards along the cutting line of the product to form a product without burrs.
Description
Technical Field
The invention relates to the technical field of hardware product processing, in particular to a hardware material belt cutting burr-free blanking process.
Background
The existing hardware material belt is generally half-cut upwards and forms a small angle on a workpiece, so that small sharp-angle burrs exist on a punched product; the process needs to add a post-procedure for deburring after punching, not only increases the production cost, but also has relatively low production efficiency, and in order to solve the problem, the invention discloses a hardware material belt cutting burr-free punching process.
Disclosure of Invention
The purpose of the invention is as follows: in order to solve the defects in the background technology, the invention discloses a hardware material belt cutting burr-free blanking process.
The technical scheme is as follows: a cutting and burr-free blanking process for a hardware material belt specifically comprises the following steps,
firstly, presetting a cutting line on the surface of a product;
secondly, respectively punching an upper pressing line and a lower pressing line on two sides of a cutting line of the product;
and thirdly, half cutting the punching die upwards along the cutting line of the product to form a product without burrs.
As a preferable mode of the present invention, the cross sections of the upper and lower nip lines are both V-shaped structures.
The invention realizes the following beneficial effects:
according to the invention, the upper pressing line and the lower pressing line are respectively punched on two sides of the cutting line of the product, so that the product is ensured to have no burrs after punching, the phenomenon that the burrs are removed by increasing the post-process after the product is punched is avoided, the production cost is reduced, and the production efficiency is improved.
Drawings
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and together with the description, serve to explain the principles of the disclosure.
Fig. 1 is a diagram of a blanking process in the prior art disclosed in the present invention.
Fig. 2 is a diagram of an improved blanking process disclosed in the present invention.
In the figure: 10. product, 20 cutting line, 30 small angle, 40 burr, 50 upper pressing line and 60 lower pressing line.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Examples
Referring to fig. 1-2, a hardware material belt cutting and burr-free blanking process specifically comprises the following steps,
firstly, presetting a cutting line 20 on the surface of a product 10;
secondly, respectively punching an upper pressing line 50 and a lower pressing line 60 on two sides of the cutting line 20 of the product 10;
third, the cutting die is half-cut upward along the cutting line 20 of the product 10 to form the product 10 without burrs.
In the present embodiment, the cross-sections of the upper and lower nip lines 50 and 60 are both V-shaped structures.
In summary, the upper pressing line 50 and the lower pressing line 60 are respectively punched on the two sides of the cutting line 20 of the product 10, so that the product 10 is ensured to have no burr 40 after being punched, the phenomenon that the burr is removed after the post-process is added to the product 10 after being punched is avoided, the production cost is reduced, and the production efficiency is improved.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
