Technical Field

The application relates to the field of cutters, in particular to the field of trimming cutters for processing non-metallic materials.

Background

Due to the development of science and technology, the modernization rhythm is accelerated, various furniture is customized to be the first choice of modern people, and the requirements of furniture customization factories on various devices are higher and higher in the furniture customization process, so that different cutters are required to be selected according to different materials and different purposes of the same material. For example, in various furniture making processes, furniture is cut. However, because the furniture customized by each manufacturer is different, the required specifications of the cutting tools are also different, so the cutting tools cannot be produced in batches through models, and each tool manufacturer can only produce a small amount of tools with a certain specification according to the requirements of each manufacturer. The cutting tools require regular maintenance and replacement due to wear.

The ubiquitous problem of the cutting tool who uses now is that the tool bit can not be replaced, and whole cutter is scrapped also after the cutter body is scrapped, and cutter body and supporting body can not reuse, and is extravagant huge. Meanwhile, the cutter body is made of an integral material, so that the material consumption is high, and the processing time is long. As shown in fig. 1.

Patent CN102292196B, milling tool and cutting element for milling tool, has drawbacks: the positioning is difficult, the process is complex, the processing is difficult, the cutter body is protruded, and the noise is high. As shown in fig. 2.

Disclosure of Invention

The purpose of the invention is as follows: the problem that the cutter body can not be recycled is solved, the positioning difficulty is solved, and the problem that the machining process is complex is solved.

The technical scheme is as follows: the trimming cutter with replaceable cutting elements is characterized by comprising a supporting body, wherein a hollow groove is formed in the supporting body, a cutter groove for mounting the cutting elements is formed in one side of the hollow groove, the front end of the cutting element is a cutter edge, the supporting body is a hollow cylinder, the hollow groove is formed below the cutter edge, and the cutter edge is higher than the outer surface of the supporting body.

Preferably, the outer surface of the carrier is provided with a plurality of empty grooves and cutter grooves, and the empty grooves and the cutter grooves correspond to each other in number one by one.

Preferably, the empty grooves and the cutter grooves are regularly or irregularly distributed on the outer surface of the bearing body.

Preferably, the point of stress of the cutting element when cutting is located at the corner of the cutting element in contact with the pocket.

Preferably, the bottom of the cutting element is designed to be a safety tooth holder, and the section of the safety tooth holder is in a diamond shape.

Preferably, the tool groove is a V-shaped groove, the cutting element is tightly attached to two surfaces of the V-shaped groove, and a small gap is formed between the section of the safety tooth holder and the bottom of the V-shaped groove.

Preferably, positioning grooves are arranged on two sides of the cutter groove.

Has the advantages that:

1. benefits of replaceable cutting elements: the cutting edge of the cutter can be replaced after being sharpened, and for the prior art, the bearing body can be continuously used, so that about two thirds of bearing body materials can be saved according to estimation. The cutting elements can be produced and installed on different bearing bodies in batches because different enterprises have different requirements on the specifications of the cutting tools, the process for producing the cutter bodies is simplified, the production time can be reduced by two thirds, and the efficiency can be improved by three times. The cutter is produced by cutting on an integral cylinder, and the protruding part of the cutter body can be deformed due to external force impact or other reasons slightly carelessly in the production process.

2. Be equipped with the dead slot on the supporting body, dead slot one side is equipped with the beneficial effect of the sword groove of installation cutting element: when the cutting element is used for cutting, the stressed part is the contact part of the cutter body and the cutter groove, the bearing body is stressed finally, the cutter groove cannot be deformed, and the bearing body can be continuously used after the cutting element is replaced. In the prior art, the cutter body is arranged in the protruded cutter groove, the cutter groove is deformed when the cutter body is stressed, and meanwhile, the cutting element cannot be replaced, so that the service life cycle of the cutter is short.

3. The cutting element base is designed as a safety tooth holder, and compared with CN102292196B, the cutting element base can omit processing and positioning structures in the preparation of a cutter body and a bearing body, thereby simplifying the process and improving the production efficiency; the section of the safety tooth holder enables the cutting element to be in seamless contact with two surfaces of the cutter groove, the stability of fixed connection is improved, and the material loss of the tooth is reduced; the damage to the positioning structure in the cutting process is also reduced, so that the service life of the cutter is prolonged; so that noise can not be generated at the rear part of the cutter body due to vibration in the cutting process.

4. The positioning groove structures are arranged on the two sides of the cutter groove, so that the precision of the fixed connection between the cutting element and the cutter groove can be improved, and the process time of the fixed connection is reduced.

Detailed Description

A cylinder is taken as a supporting body, is hollow and is provided with a groove and is used for being installed on equipment, a hollow groove and a cutter groove are dug on the outer side of the supporting body, and a cutting element to be replaced is installed at the position of the cutter groove.

And after the cutter is mounted on the equipment to work, when the cutter is worn to be not in accordance with the requirements, the cutter is cut, the cutting surface is horizontal to the upper surface of the cutter body, the cutter is cut for the last time when the rear part of the cutter body is slightly higher than the supporting body by about several millimeters, and after the cutting times are about 3 to 4 times, the cutter is taken back to a cutter factory to replace a cutting element and then is mounted on the equipment again for use.

According to the experiment, this application compares with current generally using the cutter, can practice thrift two-thirds the supporting body material, reaches energy-concerving and environment-protective requirement, because cutting element can replace simultaneously, consequently, directly install on the supporting body of different specifications after the cutting element can batch production. The production efficiency is improved by 3 times, two thirds of the production time is saved, and the structure of the prior cutter is shown in figures 3, 4 and 5

According to noise detection, the cutter noise of this application is obviously declined than current cutter noise, and the workman need not improve the sound conversation when the workshop work, also can not lead to conveying the production instruction mistake because of the noise.

The bottom of the cutting element is provided with the safety tooth seat, so that the seamless fit between the base surface of the cutting element and the cutter groove surface is ensured. According to multiple data records, the design increases the stability of fixed connection and prolongs the service life of the cutting element; this design also reduces the material loss of the teeth by up to 30%. The specific structure is shown in fig. 6 and 7.

In the product experiment stage, the inventor finds that when the replaceable element is installed in the cutter groove, a certain time is wasted in positioning, positioning grooves are designed on two sides of the cutter groove for decoding, when the replaceable element is installed, the positioning tool is placed in the positioning grooves, the time for installing the replaceable element can be reduced, and meanwhile, the positioning is more accurate. The specific structure is shown in fig. 8 and 9.
