Description
Technical field
The present invention relates to the parts of piano key, and in particular to seat board in the clamping plate of piano key.
Background technology
Piano key is equipped with middle seat board, and during installation, round pin passes through middle seat board, in order to avoid during playing, key
Swing up and down caused by round pin and middle seat board excessive friction, round pin lining need to be added on the inside of the hole of middle seat board.
Seat board during the prior art is generally made of solid wood integral type, then worn by hand for middle seat board.However the prior art
It has the disadvantage that：
1. timber has the wet characteristic to rise of drying shrinkage, at present using wood as a kind of organic material of natural polymer
Seat board in work needs strictly to control the moisture content of timber, dry and cracked and deformation is otherwise easily caused, so as to cause material scrap.
2. with the development of science and technology, the cost of raw material is gradually increasing, and automatization level is continuously improved.In order to allow
Middle seat board is realized wears round pin lining automatically, and the stability needs of material further improve, it is ensured that the accuracy of perforation makes in board
Be not in deviation during perforation, while need the processing of seat board and quality requirement in meeting.
Invention content
For the technical problems in the prior art, the purpose of the present invention is：There is provided a kind of stability height and convenient for axis
Seat board in the clamping plate of mach piano key.
In order to achieve the above object, the present invention adopts the following technical scheme that：
Seat board in the clamping plate of piano key interlocks seven layers of veneer that hot pressing forms including transverse and longitudinal successively, top layer and most lower
Layer is linden veneer, and intermediate five layers are board using poplar board；The machine direction of adjacent veneer is orthogonal.
The machine direction of linden veneer is set along the width direction of seat board in clamping plate, second, four, six layer of board using poplar board
Machine direction is set along the length direction of seat board in clamping plate, and third, the machine direction of five layers of board using poplar board are along seat in clamping plate
The width direction setting of plate.
Firstth, the thickness of seven layers linden veneer is 0.4mm, and the thickness of second, four, six layer of board using poplar board is 0.8mm, the
3rd, the thickness of five layers of board using poplar board is 1.9mm.
Using heat pressing process, hot pressing pressure 0.3Mpa.
The adhesive of veneer bonding is selected into modified urea-formaldehyde resin.
Piece is close between veneer.
Size is 1300*55mm, is cut by the clamping plate that size is 1300*1220mm obtained.
The surface of seat board is the smooth surface by the fixed thick processing of sanding in clamping plate.
The upper surface of seat board is provided with the upper hand hole passed through for round pin in clamping plate, and upper hand hole runs through all veneers；In clamping plate
The width direction of seat board is provided with perforative pit slot, and pit slot depth after axis machines is 1.2mm, and pit slot passes through the five, the six, seven
Layer veneer.
Generally speaking, the invention has the advantages that：
1. using the clamp region of veneer hot pressing, while the machine direction of adjacent veneer is orthogonal, can effectively improve production
The stability of product, while processing technology can be met in the selection of material, the automatic of round pin lining is worn automatically for seat board in realization
Change lays the foundation.
2. since middle seat board plate core is using poplar, the cost of raw material can be effectively reduced, while the quality for meeting product will
It asks.
3. since middle seat board decoration panel selects linden, existing processing technology is effectively met from material, it is fine effectively to reduce wood
The phenomenon of bursting apart of dimension.
Description of the drawings
Fig. 1 is the structure diagram of use state of the present invention.
Fig. 2 is the sectional view of the present invention.
Wherein, 1 is first layer veneer, and 2 be second layer veneer, and 3 be third layer veneer, and 4 be the 4th layer of veneer, and 5 be the 5th
Layer veneer, 6 be layer 6 veneer, and 7 be layer 7 veneer, and 8 be seat board in clamping plate, and 9 be round pin, and 10 serve as a contrast for round pin.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Seat board in the clamping plate of piano key, including the linden veneer of seven layers of veneer, respectively first layer bonded successively,
Two to six layers of board using poplar board, the linden veneer of layer 7.
Firstth, the machine direction of seven layers linden veneer is set along the width direction of seat board in clamping plate, second, four, six layer
The machine direction of board using poplar board is set along the length direction of seat board in clamping plate, third, five layers of board using poplar board machine direction edge
The width direction setting of seat board in clamping plate.Length direction is the same as the length direction of key.
Firstth, the thickness of seven layers linden veneer is 0.4mm, and the thickness of second, four, six layer of board using poplar board is 0.8mm, the
3rd, the thickness of five layers of board using poplar board is 1.9mm.
Clamping plate is obtained using hot pressing, hot pressing pressure 0.3Mpa, hot pressing time 8min, and the adhesive selection of veneer bonding is changed
Property Lauxite.Seat board size is 1300*55*6mm in clamping plate, is cut by the clamping plate that size is 1300*1220*6mm obtained.Folder
The surface of seat board is the smooth surface by the fixed thick processing of sanding in plate.Piece is close between veneer.
It after the plank of 1300*55*6mm is made, is punched by dish saw, the process implementings such as cold pressing and perforation, seat in clamping plate
The upper surface of plate is provided with the upper hand hole passed through for round pin, and upper hand hole runs through all veneers；The width direction of seat board is opened in clamping plate
There is perforative pit slot, pit slot depth after axis machines is 1.2mm, and pit slot passes through the five, the six, seven layers of veneer.Using this reality
Seat board in the clamping plate of example is applied, performance is stablized, worn available for machinery, effectively improve processing efficiency and processing quality.
Seat board wears the automation of round pin lining in realization, needs to improve the stability of material, it is necessary to from material and cost
Considered, while to meet the quality requirement of prior art and product.Pine clamp region is compared, pine is making
The requirement of odd-level cannot be met in the process, while during low slot is processed, more phenomenon of bursting apart occurs in wood-fibred, sternly
Ghost image rings the quality of product.And the decoration panel of the present invention is using linden, so as to largely reduce the phenomenon of bursting apart of wood-fibred, plate core
Using poplar, in a manner that veneer texture is orthogonal and odd-level is required to carry out assembly, can improve product stability and
It effectively reduces cost.
Above-described embodiment is invents preferable embodiment, but embodiments of the present invention are not limited by above-described embodiment
System, other any Spirit Essences without departing from the present invention with made under principle change, modification, replacement, combine, simplification,
Equivalent substitute mode is should be, is included within protection scope of the present invention.
