Abstract
The invention discloses a heating system for a veneer slicing knife, which aims at solving the problems that dorsal fissure degree of a veneer is increased, veneer surface is not smooth and blue stain is serious when a thick veneer is sliced. The heating system consists of a knife body (1), a heat insulation medium (2) and a knife rest (3), wherein, the knife body (1) is provided with a tube (6) for injecting a heat-conducting medium (9).
Description
Technical field
The present invention relates to the veneer slicer in the veneer processing, particularly the slicing cutter of vertical veneer slicer.
Technical background
Along with the raising of Chinese national economy level, the developing rapidly of China's furniture and ground board industry, particularly surface lining and solid wooden compound floor increases year by year to the demand of sliced veneer.And China carries out " wildwood protected project ", causes some regional wood raw materials, and particularly the imbalance between supply and demand of precious timber becomes increasingly conspicuous.Therefore, sufficiently and reasonably utilize existing resource, reducing wastage of material and improving crudy is the main path that solves this contradiction.
Longitudinal slicer be mainly used in the slicing of thick wooden skin and production that wooden skin is had relatively high expectations in, as veneer of multi-layer solid wood composite floor, musical instrument etc.Multi-layer solid wood composite floor requires wooden skin thickness to reach more than the 3mm-6mm, and strict control crackle and distortion, the texture of the production requirement wood skin of musical instrument (as guitar, piano) can not have any destruction, any crackle can not be arranged, otherwise can influence musical instrument effect in use.The slicing cutter that uses on the existing longitudinal slicer is at slicing thickness during greater than the above veneer of 3mm, exists easily to make veneer produce shortcomings such as dorsal fissure, plate face be rough.By to cutting region timber local heat, soften timber, increase its plasticity, can reduce cutting resistance and crack, back side degree, improve the slicing quality.
At present, have a kind of like this system, in this system, with the water-vapour spray after the heating to the blade place, with raising blade temperature, hot machining district No. 4222421, United States Patent (USP) (for example see Donald C.Walster).Also there is multiple such system, make the local rising of cutting region timber temperature by the heating nose bar, a kind of like this system is arranged, in this system, at the inner fluting of two-sided (roller) nose bar (or perforate), heat nose bar No. 3866642, United States Patent (USP) (for example see Donald C.Walster) by steam.The many factories of Canada use a kind of heating nose bar with curved surface, and it is made with mild steel, chrome-faced, and to increase wearability and to reduce frictional force, inside has steam or deep fat to pass through, but the curved surface temperature reaches 150 ℃, the hot machining district.
There is not the system that can realize all features of the present invention, in this system, realizes heating the planing tool cutter hub by optimizing the planing tool parameter, hot machining district timber, said planing tool parameter comprises planing tool structure, material and size.The installation of heating system has been simplified in this just design based on planing tool greatly, and cutting region timber is heated in real time, and this makes the present invention be different from prior art.
Summary of the invention
When the technical problem to be solved in the present invention is the thick veneer of vertical slicing, easily make veneer dorsal fissure degree increase the problem that the plate face is rough and the veneer blue stain is serious, a kind of planing tool heating system is provided, make the veneer smooth surface, reduce dorsal fissure degree and cutting resistance, eliminate the veneer blue stain.
Technical solution of the present invention is: single-plate slicing knife heating system is made of cutter hub, heat insulation medium and knife rest, and cutter hub is welded into integral body by cutting edge and matrix, and cutting edge and matrix are that two kinds of different materials are made.Cutter hub is provided with locking hole and regulates screwed hole.On the cutter hub of regulating between screwed hole and the cutting edge, be processed with pipeline, pipeline opening forms the loop of particular form after plug and soldering and sealing, in order to feed heat-conducting medium.
As improvement, pipeline is rectangular opening or circular port on the cutter hub.Pipeline is in order to feed heat-conducting medium, with the heat transferred cutter hub, and then heat transferred cutting region timber improved the temperature of cutting timber by heat-conducting medium, realizes timber is carried out emollescence.
For any single-plate slicing knife heating system recited above, the matrix material of described cutter hub is an alloy tool steel, and the material of cutting edge is high-speed steel or carbide alloy.Alloy tool steel is meant the low-alloy steel of alloying elements such as containing chromium, tungsten, silicon, manganese.Alloy tool steel has higher hear resistance (300 ℃-400 ℃), can allow to work under higher cutting speed.High-speed steel is the high-speed tool steel that has added alloying elements such as more tungsten, molybdenum, chromium, vanadium; Carbide alloy is that sintering forms powder metallurgy under HTHP with metal adhesive (cobalt, nickel etc.) for the metal carbides (tungsten carbide, titanium carbide, ramet etc.) of infusibility.They produce under the high enthusiasm condition in high-speed cutting still can keep high hardness, and HRC reaches more than 60.Experiment showed, when temperature to be higher than 550 ℃ more than-600 ℃ the time, the hardness of its high-speed steel just significantly descends, and the hardness of carbide alloy can not reduce yet.The combination of different cutter materials, both can guarantee under the situation of cutter hub heating, the cutting tip of cutter still has enough hardness, less wearing and tearing, and since the thermal conductivity of alloy tool steel than high-speed steel height, also can make the cutter hub uniformity of temperature profile, guarantee the stability of cutter, improve the durability and the service efficiency of cutter.
For any single-plate slicing knife heating system recited above, described heat-conducting medium is conduction oil or has the high heat-conducting medium of the high heat endurance of thermal conductivity factor.Adopt conduction oil or have the high heat-conducting medium of the high heat endurance of thermal conductivity factor and can continual heat be supplied to cutter hub.
For any single-plate slicing knife heating system recited above, described heat insulation medium is polytetrafluoroethylene (PTFE) or the low heat-barrier material of thermal conductivity factor with certain rigidity.Adopt the low material of thermal conductivity factor can stop, and then reduce thermal loss, the service life of improving cutter cutter hub heat transferred knife rest.
For any single-plate slicing knife heating system recited above, the temperature range of heat-conducting medium heating cutter hub is 70 ℃-300 ℃.The cutting edge of high temperature helps to make timber softening, and can improve the veneer temperature, accelerates water evaporates in the veneer, eliminates veneer blue stain phenomenon.
Technique effect of the present invention is: this system can heat the planing tool cutter hub by heat-conducting medium, the local temperature that improves cutting region timber, and softening timber increases its plasticity, and minimizing even elimination surmount the appearance in crack.The dorsal fissure degree that produces during greater than the veneer of 3mm at slicing thickness is less than 10%, and the plate face is smooth, improves the slicing quality.
