Abstract

The invention discloses a carbide-inlaid wave knife die which comprises a base, wherein a knife head is welded on the side wall of the base, a plurality of threaded holes are formed in the side wall of the base, the base is made of alloy structure hardened and tempered steel, the knife head is made of carbide alloy hardened and tempered steel, and the base and the knife head are welded through brazing flame. In the invention, only a small amount of hard alloy needs to be processed after the cutter is welded, so that the processing difficulty is greatly reduced, the processing time is reduced, and in the use process of the cutter, because the cutting contact area is small, the single blanking force is small, the accumulated blanking force is small along with continuous cutting, the abrasion of accumulated cutting materials to the cutter is small, so that the service life of the cutter is long in one time, the labor productivity is improved, and the production cost is reduced.

Description

Carbide-inlaid wave knife die

Technical Field

The invention relates to the technical field of cutting of metal packaging sheets, in particular to a carbide-inlaid wave knife die.

Background

The wave knife mold is mainly applied to the waveform cutting of metal sheets, the utilization rate of the metal sheets is improved, the resource waste is reduced, the knife mold with different waveforms is manufactured according to the shape of a required plate, the knife mold is taken as the first die production country in the world, the self-sufficiency rate of the middle-high end die industry in China is seriously low, the gap exists between the design research and development, the material process, parts and the like and advanced countries in the world, the precious development opportunity is won for the die industry in China by benefiting from the industrial policy of the country, the huge industry requirements and the continuously improved consumption requirements, and the good prospect of the die market growth is determined.

At present, carbide forming tools are mostly adopted in the wave knife moulds on the market, namely the whole tool is made of carbide materials, so that not only are material resources wasted, but also a plurality of inevitable problems are increased for the processing technology.

Based on the above, the invention provides a carbide-inlaid wave knife die.

Disclosure of Invention

The invention aims to solve the defects in the prior art, and provides a carbide-inlaid wave knife die which can save resources and reduce cost on the premise of minimizing the trimming burrs of a cut material.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides an inlay carbide ripples sword mould, includes the base, the welding of base lateral wall has the tool bit, a plurality of screw holes have been seted up to the base lateral wall, the base adopts alloy construction quenched and tempered steel to make, the tool bit adopts carbide quenching steel to make, the welding between base and the tool bit is copper borer flame welding.

Preferably, the knife edge on the cutter head is in an omega shape for cutting, and the knife edge is in a sharp angle shape.

The invention has the following beneficial effects:

in the invention, only a small amount of hard alloy needs to be processed after the cutter is welded, so that the processing difficulty is greatly reduced, the processing time is reduced, and in the use process of the cutter, because the cutting contact area is small, the single blanking force is small, the accumulated blanking force is small along with continuous cutting, the abrasion of accumulated cutting materials to the cutter is small, so that the service life of the cutter is long in one time, the labor productivity is improved, and the production cost is reduced.

Fig. 1 is a schematic structural view of a carbide-tipped wave cutter die provided by the invention.

In the figure: 1 base, 2 tool bits, 3 screw holes.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, a inlay carbide ripples sword mould, including base 1, the welding of 1 lateral wall of base has tool bit 2, and a plurality of screw holes 3 have been seted up to 1 lateral wall of base, and base 1 adopts alloy construction quenched and tempered steel to make, and tool bit 2 adopts carbide quenching steel to make, and the welding between base 1 and the tool bit 2 is copper brazing flame welding.

Furthermore, the base 1 and the tool bit 2 are welded in a segmented mode according to the shape of the knife edge when being welded, so that only a small amount of hard alloy needs to be machined after the tool is welded, machining difficulty is greatly reduced, and machining time is shortened.

The knife edge on the knife head 2 is cut in an omega shape, and the knife edge is in a sharp angle shape, so that the cutting contact area is small, the single blanking force is small, the accumulated blanking force is small along with continuous cutting, the abrasion of accumulated cutting materials to the knife is small, the service life of the knife is long at one time, the labor productivity is improved, and the production cost is reduced.

In the invention, when the cutter is manufactured, the base 1 and the cutter head 2 are welded by brazing flame, then when the cutter head 2 is subjected to cutting edge processing, a cutting edge is cut according to an omega shape by using a slow wire, only the edge cut of a rib is reserved, and the sharp angle of the cutting edge is kept.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
