Abstract

The utility model relates to a hard alloy helix planer and is a woodwork device. The utility model comprises a knife body and a knife tooth; the knife tooth is distributed on the knife body along the outer surface of the knife body in a helix linear shape. The knife tooth comprises a plurality of alloy knife heads which are cut by the helix line; and the alloy knife head is welded on the knife body. The cutting principle of the utility model is more rational; the utility model enhances the width of the practical cutting compared with the knife of the same length and tooth number; and the utility model enhance the practical working front angle. The helix knife groove brings convenience to the crumb removing. The gradually cutting of the knife head on the knife tooth greatly reduces the resistance and the knife vibration, therefore the utility model reduces the using power and the operating noises. Moreover, the special sharpening method of the utility model makes the utility model more durable.

Description

Carbide alloy spiral planer cutter

The utility model relates to the carbide alloy spiral planer cutter in a kind of wood working tool.

At present, the widely used planer cutter of carpentry is the linear knife-tooth structure, and the cutting resistance of this cutter is big and cutting blade is narrower, and the cutter groove of existing planing tool also is a straight shape groove in addition, and the cutter groove of this shape is difficult for cutting the wood chip that produces and emits.Another shortcoming of existing cutter is that the use majority of cutter tooth is its front edge of reconditioning, and the reconditioning precision is difficult for grasping, and also can influence the intensity and the life-span of cutter tooth simultaneously to the reconditioning of front edge.At existing problem in the prior art, a kind of novel planer cutter of research and design, existing problem is very necessary in the prior art thereby overcome.

In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of novel hard alloy spiral planer cutter rational in infrastructure, easy to use of research and design.

Carbide alloy spiral planer cutter described in the utility model, its structure is made up of cutter hub and cutter tooth, it is characterized in that cutter tooth be along the cutter hub outer surface in the shape of a spiral wire be distributed on the cutter hub; Cutter tooth described in the utility model is made up of many fritter alloy cutter heads that are divided into by helix, and alloy cutter head is welded on the rabbet body.

Carbide alloy spiral planer cutter described in the utility model was than the Tool in Cutting principle was more reasonable in the past, and it is wide that the planer cutter that contrasts the same length and the number of teeth has increased the actual cut blade, increased the real work anterior angle.In the work, spiral yarn shaped cutter tooth is cut gradually, has reduced cutting resistance and chatter significantly.Helical form cutter groove

Make chip removal more convenient.Thereby this product can improve crudy and working (machining) efficiency, reduction noise effectively.The utility model novel structure, save the energy, reduce noise, improve the quality and efficient, it puts goods on the market in enormous quantities and will produce remarkable social benefit and economic benefit.

Accompanying drawing of the present utility model:

The structural representation of carbide alloy spiral planer jet blade

Among the figure: 1, cutter hub 2, cutter tooth 3, alloy cutter head

Concrete enforcement of the present utility model hold the zigzag shape cutter tooth that distributing on the cutter hub of circle, and cutter tooth is made up of many alloy cutter heads as shown in drawings, because cutter tooth holds helical form, so original relatively straight-tooth has increased cutting width.Because spiral helicine knife-tooth structure, when making its work, cutter tooth is to cut gradually, thereby has reduced cutting resistance and chatter significantly, has reduced noise.Reduce the working power of planer significantly, saved the energy.Because the cutter groove also holds helical form, makes chip removal more convenient.Improve crudy and working (machining) efficiency, prolonged service life.For the large-size planer of planing tool tooth length at 250-1500mm, directly arrangement for grinding can be installed behind the dress cutter on planer, can fundamentally eliminate the error of cutter.The utility model is on probation through producer, and its cutting quality and efficient increase substantially, and is comparing with the planer cutter under equal service condition, and its reconditioning cycle is long, average reconditioning in 7-10 days once, each reconditioning 0.08mm, be 5-7 times of former cutter its service life.

Claims

1, a kind of carbide alloy spiral planer cutter, its structure is made up of cutter hub (1) and cutter tooth (2), it is characterized in that cutter tooth (2) be along cutter hub (1) outer surface in the shape of a spiral wire be distributed on the cutter hub (1).

2, carbide alloy spiral planer cutter according to claim 1 is characterized in that cutter tooth (2) is made up of many fritter alloy cutter heads (3) that are divided into by helix, and alloy cutter head (3) is welded on the rabbet body.
