When a woodworking furniture factory performs cutting and milling on wood, the strength of a cutter body at a part of a combined forming cutter can not meet the requirement, and stress concentration can occur on the integral cutter, so that the cutter is easy to break in the cutting process, and the whole cutter must be replaced after the cutter breaks, thereby wasting the customer cost.
SUMMERY OF THE UTILITY MODEL
The utility model provides a difficult cracked carpenter gang tool in cutting process to the above-mentioned not enough of prior art.
In order to achieve the above object, the utility model adopts the following technical scheme:
the woodworking combined tool comprises a first forming cutter and a second forming cutter, wherein coaxial mounting holes are formed in the first forming cutter and the second forming cutter, a plurality of first cutter heads are uniformly arranged on the outer circumference of the first forming cutter, and a plurality of second cutter heads are arranged on the outer circumference of the second forming cutter; the outer surfaces of the second cutter head and the first cutter head are both provided with cutting edges made of hard alloy materials, the lower end of the first cutter head and the upper end of the second cutter head are both provided with steps and protruding parts, and the steps on the first cutter head are in contact with the protruding parts on the second cutter head.
The utility model has the advantages that: this scheme is used for processing timber, and the cutter wholly adopts two shaping sword stack combinations, has avoided the stress concentration point on the monoblock alloy, avoids stress concentration to lead to the cutter fracture. When the two forming knives are assembled, the distance between the two forming knives can be adjusted through the gasket, and the purpose of adjusting the height of the groove opening position in the wood is further achieved. The single cutting edge on the cutter head has high hardness, is not easy to break in the cutting process, and prolongs the service life of the cutter.

Fig. 2 is a side view of the combined state of the woodworking gang tool.
The cutting tool comprises a first cutting head, a second forming cutter, a first forming cutter, a second forming cutter, a wood material, a first end face, a step, a first cutting edge, a second cutting edge, a first end face, a second end face, a first end face, a second.
Detailed Description
The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and various changes may be made apparent to those skilled in the art within the spirit and scope of the present invention as defined and defined by the appended claims.
As shown in fig. 1 and 2, the woodworking combined tool comprises a first forming cutter 9 and a second forming cutter 2, wherein the first forming cutter 9 and the second forming cutter 2 are both provided with coaxial mounting holes, four first cutter heads 13 are uniformly arranged on the outer circumference of the first forming cutter 9, and four second cutter heads 1 are arranged on the outer circumference of the second forming cutter 2; the outer surfaces of the second cutter head 1 and the first cutter head 13 are both provided with a cutting edge 6 made of hard alloy, the lower end of the first cutter head 13 and the upper end of the second cutter head 1 are both provided with a step 5 and a protruding part 7, and the step 5 on the first cutter head 13 is in contact with the protruding part 7 on the second cutter head 1.
Whole cutter passes through the mounting hole to be fixed in the pivot during installation, and step 5 and 7 contact formation locks of bulge process timber 3, and the cutter wholly adopts two shaping sword stack combinations, has avoided the stress concentration point on the whole cutter, avoids stress concentration to lead to the cutter fracture. When the two forming knives are assembled, the distance between the two forming knives can be adjusted through the gasket, and the purpose of adjusting the height of the groove in the wood 3 is further achieved. The independent cutting edge 6 on the cutter head has high hardness, is not easy to break in the cutting process, and prolongs the service life of the cutter.
The middle part of the first forming cutter 9 is provided with a convex step 12, the middle part of the second forming cutter 2 is provided with a settling step 5, and the convex step 12 is contacted with the settling step 5. A saw blade 8 is arranged between the protruding step 12 and the settling step 5, four saw blade tool bits 10 are uniformly arranged on the outer circumference of the saw blade 8, a cutting edge 6 made of hard alloy is arranged on each saw blade tool bit 10, and a through hole coaxial with the mounting hole is formed in each saw blade 8.
When the saw blade 8 is installed, the saw blade head 10 is arranged in a gap between the four first cutter heads 13 and the four second cutter heads 1, the saw blade 8 is usually made of 65Mn and 75Crl made in China, the hardness HRC value is 44-46, the first forming cutter 9 and the second forming cutter 2 are made of No. 45 steel, and the hardness HRC of the steel is less than 28, so that the saw blade 8 is higher than the hardness of the material of the forming cutter body, the strength is increased, the deformation and fracture are not easy to occur in the cutting process, and the service life of the cutter is prolonged.
The protruding step 12 and the settling step 5 are both provided with a first end surface 4 contacting with the saw blade 8, and the upper end of the first forming knife 9 and the lower end of the second forming knife 2 are both provided with a second end surface 11. The first end face 4 ensures that the saw blade 8 is fixed and stable between the first forming cutter 9 and the second forming cutter 2, and meanwhile, when the saw blade is installed, the second end face 11 is positioned, a stress surface is formed on the rotating shaft, and the saw blade is fixed and stable.
