Quick-change machine planer tool bit

Technical Field

The utility model relates to a planer tool field, concretely relates to planer tool bit for quick change machine.

Background

The planer tool for woodworking is a large tool installed on machine tool, and is used for planing, chamfering and cutting various timbers. The conventional planing tool is usually thick in order to ensure enough strength during operation, so that the planing tool can be used after being sharpened after the edge is passivated, but more professional equipment and appliances are needed during sharpening, and meanwhile, the technical requirement on sharpening personnel is high, so that most users cannot meet the condition of self-sharpening of the planing tool, most users can directly replace the whole planing tool after the planing tool is passivated, the market price of each planing tool is 200-300 yuan, the frequency of passivating the planing tool is high, the planing tool belongs to a high-consumption product, and the cost of the users is directly increased by directly replacing the planing tool.

SUMMERY OF THE UTILITY MODEL

The utility model discloses it is providing quick change machine planer tool bit to solve the problem that the replacement cost of traditional planer tool is high.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the cutting edge comprises a base body and a cutting edge fixed on the base body, wherein the thickness of the base body is 0.8-1.2mm, the cutting edge surface of the cutting edge comprises a first inclined surface and a second inclined surface which are connected with each other, the first inclined surface and the second inclined surface are positioned on the same side of the cutting edge, the second inclined surface is close to the base body, and the included angle of the first inclined surface is larger than that of the second inclined surface.

The principle and the advantages of the scheme are as follows:

1. smooth operation and long service life: traditional planer tool is in order to guarantee its life, and the cutter body is thick usually, so not only lead to production, replacement cost height, moreover when planer tool operation process smooth and easy inadequately. Therefore, in order to solve the problem, the inventor tries various ways, firstly considers the improvement of the structure, but the small blade which belongs to the standard part has very limited improvement places, and then considers the adjustment of the material formula to improve the strength of the plane cutter, but the effect is not ideal. And finally, the inventor sets the blade surface of the blade into a first inclined surface and a second inclined surface with different included angles, so that the smoothness of the cutter head during operation is improved, and the service life of the cutter head is prolonged. Later analysis shows that the first inclined plane is close to the cutting edge so as to contact with the processing material firstly, and the included angle of the first inclined plane is larger than that of the second inclined plane, so that the sufficient strength is ensured when the first inclined plane is contacted with the processing material. The included angle of the second inclined plane is smaller than the included angle of the first inclined plane, namely the second inclined plane is slightly lower than the lower part of the first inclined plane, so that the contact area of the cutting edge surface and a processing material is reduced during the operation of the planer tool, and the processing resistance is reduced to ensure that the planer tool is smoother during the operation.

2. The volume is frivolous, exempt from to repair and grind and replacement cost is low: through the first inclined plane and the second inclined plane which are provided with different included angles, the smoothness degree of the planing tool during operation is guaranteed, and the strength of the planing tool is guaranteed at the same time, so that the thickness of the tool bit is designed to be 0.8-1.2mm by utilizing the advantages of the structure, the product is small and light, and the production cost is reduced. Meanwhile, the price of the tool bit is about 50 yuan, compared with the traditional planer tool which is replaced by 200-300 yuan, the cost is reduced by 4-6 times, and the tool bit can be accepted by users, so that the scheme has a wide market prospect.

Preferably, as an improvement, the included angle of the first inclined surface is 5 degrees to 15 degrees greater than that of the second inclined surface, and experiments prove that when the included angle is less than 5 degrees, although the service life of the cutter head is not affected, the operation resistance is increased, and the planing efficiency is reduced. When the angle is larger than 15 °, the service life of the cutter head is greatly affected.

Preferably, as an improvement, the included angle of the first inclined plane is 45 degrees to 55 degrees, and experiments prove that when the included angle of the first inclined plane is smaller than 45 degrees, the strength of the cutting edge is reduced, so that the service life of the cutter head is influenced, and when the included angle of the first inclined plane is larger than 55 degrees, the cutting edge is blunt, the operation efficiency of the cutter head is seriously influenced, and meanwhile, the service life is greatly reduced. The included angle of the second inclined plane is 35-45 degrees. When the included angle on second inclined plane is less than 35, will reduce the holistic intensity of cutting edge, when the included angle on second inclined plane is greater than 45, first inclined plane tends to be close to with the second inclined plane, resistance when will increase the tool bit operation to influence planer tool operating efficiency.

Preferably, as an improvement, the hardness of the cutting edge is greater than that of the substrate, so that during production, the substrate part can be made of a material with relatively low hardness, on one hand, the production cost is reduced, on the other hand, the processing difficulty is reduced, and on the other hand, the hardness of the substrate is low, so that the difficulty in processing a hole on the substrate is reduced.

Preferably, as an improvement, the roughness of the first inclined plane is 0.1-0.2 μm, and on the basis of the above characteristics, the initial roughness of the first inclined plane is set to 0.1-0.2 μm, which not only ensures the strength of the blade but also improves the sharpness of the blade, and in addition, if the roughness is greater than 0.2 μm, the sharpness of the blade is reduced, and if the roughness is less than 0.1 μm, the processing difficulty and the processing cost are increased.

Preferably, as a modification, the width of the first slope is narrower than the width of the second slope. Through the arrangement, the strength of the cutting edge is ensured, and the resistance of the cutter head during operation is reduced.

Preferably, as a modification, the width of the first inclined surface is one fourth of the width of the second inclined surface, and by the arrangement, the strength and smoothness of the cutting edge during operation of the cutter head can be optimized.

Preferably, as an improvement, the cutting edge comprises two cutting edges, and the two cutting edges are respectively positioned at two corresponding sides of the base body. Through the arrangement, after the cutting edge on one side is passivated, the cutting edge on the other side can be continuously used, so that the utilization rate of the cutter head can be improved.

Preferably, as an improvement, offer on the base member and be used for with the mounting hole of knife rest lock installation, through the aforesaid setting, after the planer tool passivation appears, compare but other fixed modes such as welding quick replacement planer tools.

Preferably, as an improvement, the mounting holes are two, and one of the mounting holes is in a strip shape. Through the setting, set one of them mounting hole into the bar shape, the surplus that the mounting hole through the bar shape was left, the installation of being convenient for on the one hand, even the distance of two adjacent mounting holes produced certain error when production, also can be through this surplus for the installed part that corresponds on two mounting holes can be quick and the knife rest is aimed at. On the other hand, the position precision requirement between the two mounting holes is reduced, so that the processing difficulty is reduced, and the rejection rate is reduced.
