Abstract
The utility model relates to the technical field of crushing and grinding tools, in particular to a reinforced ring multi-section type cutting pick which comprises a lower base body, wherein an installation handle is arranged below the base body, and a tooth point made of hard alloy upwards is arranged on the base body; the basal body below the tooth tip is also provided with a reinforcing ring, which is characterized in that: the reinforcing ring is composed of 2-10 arc blocks, and is made of hard alloy, polycrystalline diamond compact or polycrystalline diamond; the cutting pick has the advantages of low cost, low precision requirement, difficult cracking and small stress.
Description
Technical Field
The utility model belongs to the technical field of broken, the grinding tool technique and specifically relates to relate to a pick, the pick use in the engineering dig, coal mining, tunnelling, highway mill plane and ditching fields such as grooving soon.
Background
The cutting pick is an easily-consumed article arranged on the mining equipment and mainly acts on the rock.
The cutting pick head comprises a lower base body, a mounting handle is arranged below the base body, and a tooth tip made of hard alloy and facing upwards is arranged on the base body; in the patent document with publication number CN208153014U and patent number 201820531099.1, a novel high wear-resistant cutting pick is disclosed, which comprises a base body, a tooth handle below the base body, a tooth head with a table structure above the base body, a tooth tip mounting groove on the tooth head, and a tooth tip mounted in the mounting groove, wherein a layer of reinforcing ring is bonded on the base body below the tooth tip, and the reinforcing ring is an integral body, and has the disadvantages of high cost, high precision requirement, easy cracking and large stress.
Disclosure of Invention
The objective of the present invention is to provide a cutting pick with low cost, low precision requirement, less crack and less stress, i.e. a cutting pick with multi-segment reinforcing ring.
The technical scheme of the utility model is realized in such a way that the cutting pick with the multi-section reinforcing rings comprises a base body below, wherein an installation handle is arranged below the base body, and a tooth point made of hard alloy upwards is arranged on the base body; the basal body below the tooth tip is also provided with a reinforcing ring, which is characterized in that: the reinforcing ring is composed of 2-10 arc blocks.
Furthermore, the reinforcing ring is made of hard alloy or polycrystalline diamond compact.
Further, the reinforcing ring is connected with the base body through brazing.
Further, the base body is provided with a groove, and the reinforcing ring is arranged in the groove.
Further, the width D of the reinforcing ring is 1-10mm, and the thickness H of the reinforcing ring is 1-20 mm.
Furthermore, the inner side of the reinforcing ring is connected with the periphery below the tooth tip.
The utility model has the advantages that: the cutting pick has the advantages of low cost, low precision requirement, difficult cracking and small stress.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, 2 and 3, the multi-segment type cutting pick with the reinforcing ring comprises a base body 1 below which a mounting shank 2 is arranged, and a tip 3 made of hard alloy and facing upwards is arranged on the base body; the basal body below the tooth tip is also provided with a reinforcing ring 4, which is characterized in that: the reinforcing ring is composed of 2-10 arc blocks 6.
The utility model discloses set up like this, have the required precision of making the beaded finish low, make more easily, reduction in production cost, stress is less, be difficult for the advantage that bursts apart.
Furthermore, the reinforcing ring is made of hard alloy or polycrystalline diamond compact.
Further, the reinforcing ring is connected with the base body through brazing.
Further, the base body has a groove 5, and the reinforcing ring is mounted in the groove.
Further, the width D of the reinforcing ring is 1-10mm, and the thickness H of the reinforcing ring is 1-20 mm.
Furthermore, the inner side of the reinforcing ring is connected with the periphery below the tooth tip 3.
The above is to ensure the strength of the reinforcing ring.
Preferably, the arc-shaped blocks are 4, 5 and 6 blocks.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
