Abstract
The utility model provides a U shaped caking tool bit and a caking saw bit, which comprises a caking tool bit and a saw bit. The caking tool bit is characterized in that the cross section of the caking tool bit is approximately of U shape, and a groove is arranged at the upper part in the thickness direction, while the saw bit, which comprises a base and a caking tool bit welded on the base, is characterized in that the cross section of the caking tool bit is approximately of U shape, and a groove is arranged at the upper part in the thickness direction. Due to the structure that a groove is arranged on the U shaped caking tool bit, the contact surface between the caking tool bit and the outside material is increased, the cooling condition of the caking tool bit is improved so that the caking tool bit is cooled rapidly during cutting, and the hear deformation of the caking tool bit can be avoided to guarantee a long time and stable working condition. The cutting depth of a saw bit with the U shaped caking tool bit is up to 1/5 of the diameter of the saw bit and is twice as deep as the tool pit in prior art, and thus the cutting efficiency is greatly improved.
Description
Technical field
The utility model relates to building materials cutting tools such as stone material, pottery, particularly a kind of U type joint piece cutter head and saw blade thereof.
Background technology
With reference to Fig. 4, Fig. 5.The structure of common building materials cast-cutting saw slice is on the market: the joint piece cutter head 4 that it comprises matrix 3 and is welded on the matrix periphery.As shown in Figure 5, existing joint piece cutter head 4 is rectangular substantially.In cutting process, the saw blade fast rotational drives joint piece cutter head 4 fly-cutting objects, joint piece cutter head 4 and object frictional heating, and existing rectangular joint piece cutter head 4 cooling condition deficiencies, and the depth of cut of saw blade can not surpass 1/10th of saw blade diameter.Because joint piece cutter head 4 unreasonable structure of existing saw blade, joint piece cutter head 4 easily heating distortion in the process of cutting object cause the degree of depth of saw blade cutting object restricted, and cutting efficiency is low.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of U type joint piece cutter head and saw blade thereof are provided, and joint piece cutter head is improved save the cooling condition of piece cutter head, increases the depth of cut of saw blade, improves the saw blade cutting efficiency.
The utility model adopts following technical scheme:
U type joint piece cutter head comprises joint piece cutter head, and it is characterized in that: the cross section of described joint piece cutter head is the U type substantially, and its top has groove along thickness direction.
The width of described groove is the 1/2-1/5 of joint piece cutter head length, and its degree of depth is the 1/3-2/3 of joint piece cutter head height.The bottom of groove is a circular arc.
The utility model also provides a kind of saw blade, comprises matrix and the joint piece cutter head that is welded on the matrix, and it is characterized in that: the cross section of described joint piece cutter head is the U type substantially, and its top has groove along thickness direction.
Groove on the described joint piece cutter head is along the radially extension of matrix, and the width of groove is the 1/2-1/5 of joint piece cutter head length, and its degree of depth is the 1/3-2/3 of joint piece cutter head height.The bottom of groove is a circular arc.
Operation principle of the present utility model: when above-mentioned saw blade cuts object, groove on the U type joint piece cutter head has increased joint piece cutter head and outside contact-making surface, improved the cooling condition of joint piece cutter head, envoy's piece cutter head cools off fast, it is overheated and be out of shape impaired in cutting process to avoid saving the piece cutter head, thereby increase the depth of cut of saw blade, cutting efficiency improves greatly.
The utlity model has following advantage:
The U type joint piece cutter head that the utility model provides, its cross section is the U type substantially, its top has groove along thickness direction, utilize this groove to increase joint piece cutter head and outside contact-making surface, improved the cooling condition of joint piece cutter head, envoy's piece cutter head is cooling fast in cutting process, and it is overheated and be out of shape impairedly during object in cutting to prevent to save the piece cutter head, guarantees the long-time steady operation of joint piece cutter head.Device has the depth of cut of the saw blade of above-mentioned U type joint piece cutter head can reach 1/5 of saw blade diameter, is the twice of existing cutter head depth of cut, and cutting efficiency improves greatly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the structural representation of U type joint piece cutter head.
Fig. 2 is the schematic perspective view of U type joint piece cutter head.
Fig. 3 is the structural representation that device has the saw blade of U type joint piece cutter head.
Fig. 4 is the structural representation of existing cutter head.
Fig. 5 is the structural representation of existing saw blade.
The specific embodiment
With reference to accompanying drawing 1,2.U type joint piece cutter head, it comprises that cross section is the joint piece cutter head 1 of U type substantially, has groove 11 on the top of joint piece cutter head 1 along thickness direction; The width of this groove 11 is the 1/2-1/5 of joint piece cutter head 1 length, and its degree of depth is the 1/3-2/3 of joint piece cutter head 1 height.Under the prerequisite that guarantees joint piece cutter head mechanical strength, the big I of groove 11 is selected to determine according to actual needs in above-mentioned scope according to the difference of joint piece cutter head 1 field of employment.The bottom of groove 11 is a circular arc.
With reference to accompanying drawing 3.The utility model also provides a kind of saw blade, and it comprises matrix 2, is welded with the joint piece cutter head 1 that above-mentioned cross section is the U type substantially at interval at the periphery of matrix 2, and the top of joint piece cutter head 1 has groove 11 along thickness direction.Groove 11 saves the radially extension of the upper surface of piece cutter head 1 along matrix 2 from the U type.
When above-mentioned saw blade cuts object, because joint piece cutter head 1 top is provided with groove 11, joint piece cutter head 1 and outside contact-making surface have been increased, improved the cooling condition of joint piece cutter head 1, envoy's piece cutter head 2 cools off fast, avoid saving piece cutter head 1 in cutting process overheated and be out of shape impaired, thereby increase the depth of cut of saw blade, cutting efficiency improves greatly.The depth of cut of saw blade can reach 1/5 of saw blade diameter, is the twice of existing saw blade depth of cut, and cutting efficiency improves greatly.
