Description
technical field:
The utility model relates to piano and manufactures field, particularly a kind of piano soundboard stall bars gummed shaping equipment.
background technology:
Piano soundboard is made up of parts such as sounding board, stall bars, crown cut, soundboard frames.Make sound have continuity, soundboard must be cambered surface protuberance.Its concave surface is stained with stall bars, and convex surface is equipped with crown cut.
Stall bars are the indispensable ingredients of soundboard, and it bears larger tension in soundboard, and stall bars two ends are designed to oblique rhombus, are designed to the arc of projection slightly with the bonding plane of sounding board.
Stall bars can be strengthened the intensity of sounding board, and opposing is from the pressure of crown cut.Because sound wave is different with the velocity of propagation while crossing annual ring along annual ring in timber, acoustic vibration is by any point on crown cut, and to cross annual ring direction fast than passing to pass to suitable annual ring direction.Therefore, cross annual ring direction and want bonding stall bars on soundboard, it is vertical with sounding board gluing, sound wave is propagated along crown cut from shot point, in the time running into the stall bars that cross annual ring, sound wave is just transmitted to monoblock soundboard sound wave rapidly along stall bars, makes the fully vibration of soundboard entirety.
Soundboard coordinates with stall bars firmly, to reducing the loss of soundboard vibrational energy, improves soundboard vibration ability, reduces sound attenuating significant.The sizing of tradition soundboard stall bars gummed, by pre-processed soundboard and stall bars bar, be coated with glue bond, adopt again the pressurization of the clamping such as fixture, jig, solidify, sizing, this gummed mode is easily destroyed soundboard and the original arcuate structure of stall bars, and the inhomogeneous stall bars that easily cause that pressurize come unglued, and affect sound equipment and the load-bearing capacity of soundboard.
utility model content:
The utility model provides a kind of piano soundboard stall bars gummed shaping equipment, has solved above-mentioned easy destruction soundboard stall bars structure, and stall bars easily come unglued, and affect sound equipment and the load-bearing capacity of soundboard.
Technology solution of the present utility model is as follows: a kind of piano soundboard stall bars gummed shaping equipment, it includes frame, be fixed on the cover half device of frame lower end, rack-mounted die device, and drive the jacking gear of described die device vertical lifting, described cover half device includes mold base, and described mold base upper end is provided with arc module; Described die device includes lower platen, and described lower platen lower surface evenly has multiple T-shaped grooves that extend longitudinally, and is inserted with the positioning strip of I shape in described T-shaped groove, and described positioning strip lower surface is fixed with hydraulic cylinder group.
Further, described jacking gear includes the top board that is fixed on frame upper end, between described top board and mold base, both sides are separately installed with screw lifting device, described screw lifting device includes supporting seat, leading screw, screw slider, described screw slider and lower platen outside are fixing, described leading screw upper end is connected with servomotor, and described servomotor is fixed on top board upper end.Adopt driven by servomotor screw lifting device, lifting is stable, is convenient to control.
Further, the spacing of described T-shaped groove is 30mm ~ 45mm, and the quantity of described positioning strip is 9 ~ 17.The quantity of stall bars depends on the size with sounding board, little upright piano to large grand piano be 9 ~ 17 not etc., the quantity of positioning strip is set according to the conventional quantity of stall bars; The arrangement pitches of stall bars is 90mm ~ 140mm, and treble is closeer, and bass area is thinner, and the spacing of T-shaped groove, according to stall bars conventional spread spacing setting, facilitates the adjustment of positioning strip spacing simultaneously.Can, according to the actual quantity of stall bars and arrangement pitches, adjust positioning strip quantity and spacing, easy to assembly.
Further, described in every group, on the telescopic end of hydraulic cylinder group, be longitudinally fixed with flexible arc press strip.Hydraulic cylinder group can not destroyed stall bars and soundboard structure while making stall bars and soundboard gummed fixing pressing down.
Further, between described mold base and arc module, be also provided with heating plate.Heating plate heating stall bars and soundboard viscose glue medium, make it accelerate to solidify, and enhances productivity.
Further, described hydraulic cylinder group, servomotor and heating plate are connected with control system.
Control system includes temperature monitoring module, setting value load module and control signal output module, temperature monitoring module and setting value load module are to heating plate heating-up temperature monitoring setting, and setting value load module and control signal output module control servomotor and hydraulic cylinder group are opened.
The beneficial effects of the utility model are:
The cover half device and the die device that coordinate with soundboard, stall bars by setting, help soundboard and the sizing of stall bars gummed rear arc, by adjusting positioning strip quantity and spacing, coordinate actual quantity and the arrangement pitches of stall bars, evenly pressurization, is fully adhesively fixed soundboard stall bars, has improved product quality, and heating plate quickening viscose glue medium is set on cover half device and solidifies, thereby enhance productivity.
