Abstract
The invention relates to a welding technology applied to the wood field. Woods are welded through a vibration friction welding technology, an ultrasonic welding technology and a linear welding technology; and the woods can be welded together instantly by the three welding technologies according to changes of temperature, pressure and vibration speed. The woods are connected together by adopting a welding technology instead of adopting a wood adhesive, so that the wood adhesive is avoided and pollution of the wood adhesive to the environment is prevented. By the welding technology, the woods are connected together according to the changes of the temperature, the speed and the pressure, deformation, flaws, hidden cracks and air holes which are generated during welding are reduced, the number of effective crystallized nucleuses is increased, skip welding is avoided and the welding quality is improved; furthermore, by the welding technology, the woods are welded together instantly, so the welding time is saved, the working efficiency is improved by 30 percent, and the blank of wood welding in the welding field is filled.
Description
Technical field
The present invention relates to a kind of solder technology, particularly a kind of solder technology that is applied to the timber field.
Background technology
Solder technology is exactly under high temperature or the condition of high voltage, makes welding material such as welding rod or welding wire two or more than two mother metal be connected into the method for operating of an integral body.Solder technology is along with the application of metal occurs, Welding Techniques in Ancient rests on the level of cast welding, smithwelding and soldering for a long time, the thermal source that uses all is a stove fire, temperature is low, energy is not concentrated, can't be used for the welding of heavy in section, long weld seam workpiece, can only be in order to make ornament, simple tools and weapon.
Present stage, solder technology mainly contained technology such as linear welding, vibration friction welding, ultrasonic bonding, but all be applied on metal, the plastic or other material, this method can be eliminated welding deformation, crackle, latent the splitting that produces in layer internal stress and the welding process, reduce cinder hole, pore, increase more, more healthy effective nuclei of crystallization in the weld seam bath, crystal grain thinning, prevent skip welding, improve welding quality and the mechanical property of materials and fatigue life.Solder technology has replaced solvent viscose glue, mechanical fixation and other technique for sticking, is a kind of advanced person's mounting technology.But the wood adhesive that combines and be to use mostly at timber welding field timber, because cure stage, so bonding timber is more time-consuming, utilize adhesive that a bad environment problem is also arranged, adhesive is easy to generate formaldehyde, contaminated environment and being detrimental to health, though timber can stick with glue agent and connected present stage, the timber vibration welding technology is still blank.
Summary of the invention
In order to address the above problem, the present invention proposes a kind of solder technology that is applied to the timber field, the present invention can weld timber by the vibration Friction welding technique, the timber that preliminary treatment is good is put on the vibration welding machine aluminum die, timber is fully clamped, the frequency of vibration welding machine is adjusted to 200Hz, the amplitude of weld displacement is 0.8 millimeter, timber is welded, and timber makes two blocks of timber welded together by the vibration change wood structure of vibration welding machine.The present invention can weld timber by the supersonic welding connection technology, at least one several ultrasound lines at regular intervals of extending downwards that are word order are set on first binding face of timber, the bottom of each ultrasound lines is that ultrasound lines is dissolved head, a ultrasonic tank that equates with the arrow number of the family line that becomes is set on second binding face of another timber, and the bottom surface of ultrasonic tank is an inclined downward.The present invention can weld timber by the string bead connection technology, and timber is placed on the hydraulic vibration gen, and timber shakes with certain amplitude, frequency under the drive of hydraulic vibration gen.
Beneficial effect of the present invention is: timber is connected take solder technology to connect; be through with and connect the epoch of timber with wood adhesive; make it avoid the use wood adhesive; reach the fixation between timber; avoided the wood adhesive pollution on the environment, the operator's is healthy thereby protected.This solder technology connects together timber by the change of temperature, speed, pressure, the welding deformation that uses this solder technology to reduce to produce in the welding process, crackle, latently split, pore, effective nuclei of crystallization have been increased, avoided skip welding, improved welding quality and the mechanical property of materials and fatigue life, the present invention welds together timber moment, save weld interval, improved 30% operating efficiency, remedied the blank of the central timber welding of welding field simultaneously.
The specific embodiment
The present invention is example with the oak, but welding timber is not limited to oak.
Embodiment 1
Oak is cut into 150 millimeters long, 15 millimeters high, the oak sample of 20 mm wides in advance, then the oak sample is submerged in the water 30 minutes, after from water, taking out oak is put on the vibration welding machine aluminum die, oak is fully clamped, the frequency of vibration welding machine is adjusted to 200Hz, the amplitude of weld displacement is 0.8 millimeter, and the oak sample is welded, and oak makes two blocks of timber welded together by the vibration change oak structure of vibration welding machine.
Embodiment 2
At least one several ultrasound lines at regular intervals of extending downwards that are word order are set on first binding face of oak, the bottom of each ultrasound lines is that ultrasound lines is dissolved head, a ultrasonic tank that equates with the arrow number of the family line that becomes is set on second binding face of another oak, and the bottom surface of ultrasonic tank is an inclined downward; Two oaks are respectively charged in separately the mould, and the ultrasound lines of an oak is inserted in the ultrasonic tank of another oak, in ultrasonic tank, leave certain clearance, start supersonic generator, the ultrasound lines of one oak is dissolved head dissolve in the ultrasonic tank of another oak, moment also welds together two oaks.
Embodiment 3
The oak A that will weld is carried out manual installation, oak B is progressively close to oak A under the promotion of hydraulic jack, oak A begins vibrations with certain amplitude, frequency under the drive of hydraulic vibration gen, after the contact of two oaks, under the effect of certain friction pressure, begin friction, producing heat deforms frictional interface, after setting fraction time, bumper stops vibrations, oak A carries out upset under the effect of hydraulic jack, after will weld good oak after upset finishes and drawing off, hydraulic jack drive workbench retreats, welding is finished, and welding job finishes.
