Description

Shape-proof balsawood pressing mechanism

Technical Field

The utility model relates to a ligneous compression fittings, especially a light wood pressing mechanism of preapring for an unfavorable turn of events shape.

Background

The wind blades can be made of various materials, such as wood, metal alloy, glass fiber reinforced plastic and the like. The wood is widely applied to miniature and small-sized wind generating sets due to the characteristics of low cost, simple manufacture and the like. Among the wood wind blades, light wood is preferred because of its low density and high power generation efficiency. In order to ensure the stability of the quality in the manufacturing process of the light wood wind blade, the parent material is usually formed by pressing wood plates. In the manufacturing process of the base material, in order to ensure the bonding strength of the glue after the pressing, the base material can still be pressed for a long time after the pressing. However, the light wood has poor self-supporting strength due to low density, and when a common pressing mechanism presses the light wood, the light wood is usually irreversibly flattened, so that the material characteristics of light weight and good rebound resilience of the light wood are seriously damaged.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned not enough, the utility model aims to provide a pressing mechanism of shape balsawood of preapring for an unfavorable turn of events, the rapid curing of glue when can realizing the pressfitting plank shortens pressfitting hold time, and then reduces the deformation of balsawood.

In order to achieve the above purpose, the technical scheme of the utility model is that:

the utility model provides a dabber pressing mechanism of preapring for an unfavorable turn of events shape, includes the brace table, and the symmetry sets up the centre gripping strip on the mesa of brace table, and the brace table top sets up the lamination device frequently that surpasses, the lamination device frequently that surpasses includes the guide rail that the level set up, and the guide rail is slided and is established the slider, and the slider sets firmly the first pneumatic cylinder transmission in guide rail one end with the level and is connected, and the below fixed connection of slider frequently vibrator frequently that surpasses vertically sets up the second pneumatic cylinder below the vibrator frequently, the tip level of second pneumatic cylinder sets up the double-rod pneumatic cylinder, and the both ends symmetry of double-rod pneumatic cylinder sets up the clamping jaw, the below of double-rod pneumatic cylinder is still the level and sets up the clamp plate, the lower.

Further, the lower surface of clamp plate still is provided with pressure detection terminal, pressure detection terminal with the second pneumatic cylinder electricity is connected.

Furthermore, the clamping strip is L-shaped, and a waist-shaped hole is formed in one side edge of the clamping strip.

The working principle is as follows: when carrying out the plank pressfitting, feeding mechanism sends into the plank that the upper surface has glue between two centre gripping strips on the brace table and makes the plank by the centre gripping of centre gripping strip and can not remove, and first pneumatic cylinder action afterwards drives slider horizontal migration and deposits the position of plank to the brace table outside directly over, then the second pneumatic cylinder stretches out the telescopic link downwards and drives the third telescopic link downstream. It should be noted that, at this time, the telescopic rod of the double-rod hydraulic cylinder is in an extended state. And along with the descending of the double-rod hydraulic cylinder, the pressing plate positioned below the double-rod hydraulic cylinder slowly approaches the wood board. When the press plate is contacted with the wood board, the photoelectric probe arranged on the lower surface of the press plate is triggered to send signals to the second hydraulic cylinder and the double-rod hydraulic cylinder respectively. And the second hydraulic cylinder stops extending out of the telescopic rod after receiving the signal. After the double-rod hydraulic cylinder receives the signal, the telescopic rods at the two ends synchronously retract to set the stroke, and then the clamping jaws are clamped on the edge of the wood board. The first hydraulic cylinder is then retracted to the initial position, whereupon the board is also moved directly above the glued board. Then, the second hydraulic cylinder extends the telescopic rod again, so that the two wood boards are abutted against each other with small pressure. Then the over-frequency vibrator acts to enable the two wood boards to generate over-frequency friction, a large amount of heat is generated in the friction process, and moisture in the glue is quickly evaporated to accelerate curing. When needing to be explained, the over-frequency vibration time is preferably set to be 5-10S, so that the situation that the two wood boards still vibrate and cannot be twisted when glue is completely cured is avoided. After the two wood boards vibrate for a set time in an overclocking mode, the second hydraulic cylinder pressurizes to enable the two wood boards to be quickly pressed, and then the base material after pressing and forming can be taken down. After the bonding is finished, the second hydraulic cylinder and the double-rod hydraulic cylinder respectively return to the initial state and are separated from the base material. The worker takes the base material off the support table.
