Abstract

The invention discloses a manufacturing technology for changing bent wood into straight wood, which comprises the following steps: 1, soaking; 2, entrucking; 3, putting onto a straightening machine; 4, heating; 5, re-clamping; 6, cooling; and 7, forming. The manufacturing technology is unique; the structure of equipment is simple; the use is convenient; the effect is obvious; the wood is fully utilized; the produced end product is reduced; and the quality stability and reliability of the product are ensured.

Description

Timber changes curved cut-off manufacture craft

Technical field

The present invention relates to a kind of improvement of wood processing technique, it is mainly used in correcting the wood-bending degree, and its flexibility is reduced significantly, is particularly using some more valuable materials.

Background technology

In order to take full advantage of material, often to try every possible means to make the wood-bending degree to reduce in the timber process, traditional way is roasting straight with fire, namely sprinkle up more roasting with burning at the sweep water, the wood-bending degree is diminished, and this way efficient is low, and intensity of variation is slow.

Summary of the invention

Task of the present invention is to provide a kind of timber to change curved cut-off manufacture craft, and this manufacture craft is unique, successful, technological process is simple, and equipment is novel, is fully used after timber processing, effectively reduce production costs, the more stable quality of product, reliable.

task of the present invention is to complete in such a way, at first the manufacture craft that this timber changes curved cut-off is placed on the wood workpiece that will process in tank soaks more than 24 hours, then the wood workpiece that soaks is placed on the dolly clamping plate on outer guide, several swages are housed on the dolly clamping plate, swage is clamped converted timber, open protecgulum, dolly moves into timber from outer guide and changes on the interior guide rail of curved cut-off machine inside, then close protecgulum, electric cabinet enters duty, heated 100～120 minutes under the condition of high temperature of 200 ℃～210 ℃, the automatic alarm prompting, turn off power supply, open subsequently protecgulum, dolly is back into outer guide from interior guide rail, at this moment the swage on dolly will further be tightened, and allow timber naturally cool down at leisure, crooked wood workpiece is subject to the traction generation distortion to a certain degree of swage, its flexibility is diminished, if necessary, can repeat once according to this manufacture craft, thereby the wood workpiece flexibility that makes processing straightens gradually and reaches technological requirement.

Description of drawings

The invention will be further described below in conjunction with accompanying drawing.

Fig. 1 is that timber of the present invention changes curved cut-off fabrication processing figure.

The specific embodiment

We can know from flow chart, and timber changes curved cut-off manufacture craft and mainly divides poly-carrying out of following step.

1, soak: the wood workpiece of needs processing is put in tank soaked, require soak time making the deliquescing of wood workpiece inner materials more than 24 hours.

2, entrucking: then pick up in the tank be loaded into the dolly clamping plate through the wood workpiece that soaks within, and marshalling.

3, upper swage: several swage is equipped in dolly clamping plate both sides, treats that wood workpiece has loaded immediately with swage, they to be clamped.

4, heating: the protecgulum that changes curved cut-off machine is opened, then dolly is pushed interior guide rail dolly to from outer guide and is entered the inside that changes curved cut-off machine, close protecgulum, electric cabinet enters duty, heated 100～120 minutes under the condition of high temperature of 200 ℃～210 ℃, it can be pointed out by automatic alarm, turns off power supply.

5, clamp: open protecgulum, push dolly to outer guide from interior guide rail, at this moment swage will hold the wood workpiece after heat treatment tighter again.

6, cooling: as subsequently the wood workpiece on dolly slowly to be cooled down, wait until after wood workpiece naturally cools to normal temperature always and loosen again swage.

7, moulding: crooked wood workpiece flexibility is straightened by a series of actions so, generally once just energy moulding, if some wood workpiece bending is too large, can carry out again single treatment according to above-mentioned operation, make the degree of crook of wood workpiece can meet our needs.

It is unique that this timber changes its technological process of cut-off manufacture craft, and device structure is simple, and is easy to operate, result of use is obvious, can take full advantage of timber, rarer expensive timber, so both reduce production cost, also guaranteed constant product quality, reliable.

Claims

1. a timber changes curved cut-off manufacture craft, it is characterized in that: at first the wood workpiece of processing is put in tank and soaked more than 24 hours, then will be placed on the dolly clamping plate of outer guide through the wood workpiece that soaks, several swages are housed on the dolly clamping plate, swage is clamped wood workpiece, opening the protecgulum dolly moves into timber from outer guide and changes on the interior guide rail of curved cut-off machine inside, close its protecgulum, electric cabinet enters duty, heated 100～120 minutes under the condition of high temperature of 200 ℃～210 ℃, it can be pointed out by automatic alarm, turn off power supply, open subsequently protecgulum, shift dolly onto outer guide from interior guide rail, at this moment to further tighten the swage on dolly, and allow wood workpiece naturally cool down at leisure.

2. the timber by claim 1 defined changes curved cut-off manufacture craft, it is characterized in that: can repeat once according to this manufacture craft, processed wood workpiece flexibility little by little be straightened satisfy technological requirement.
