Description
technical field:
The present invention relates to piano and manufacture 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 swell in cambered surface.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 slightly protruding arc with the bonding plane of sounding board.
Stall bars can strengthen the intensity of sounding board, resist the pressure from crown cut.Because sound wave is different with velocity of propagation when crossing annual ring along annual ring in wood, acoustic vibration, by any point on crown cut, passes to along annual ring direction that to cross annual ring direction fast than passing to.Therefore, soundboard crosses annual ring direction and wants bonding stall bars, it is vertical with sounding board gluing, sound wave is propagated from shot point along crown cut, when running into the stall bars crossing annual ring, sound wave is just transmitted to monoblock soundboard sound wave rapidly along stall bars, makes the overall fully vibration of soundboard.
Soundboard coordinates with stall bars firmly, to the loss reducing 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, fixture, jig etc. is adopted to clamp pressurization again, solidification, sizing, this gummed mode easily destroys soundboard and the original arcuate structure of stall bars, and the uneven stall bars that easily cause that pressurize come unglued, and affect sound equipment and the load-bearing capacity of soundboard.
summary of the invention:
The invention provides a kind of piano soundboard stall bars gummed shaping equipment, solve above-mentioned easy destruction soundboard stall bars structure, stall bars easily come unglued, and affect sound equipment and the load-bearing capacity of soundboard.
Technology solution of the present invention 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-slot extended longitudinally, and is inserted with the positioning strip of I shape in described T-slot, and described positioning strip lower surface is fixed with hydraulic cylinder group.
Further, described jacking gear includes the top board being 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, fix outside described screw slider and lower platen, 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-slot 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 sets according to stall bars conventional amounts; The arrangement pitches of stall bars is 90mm ~ 140mm, and treble is closeer, and bass area is thinner, and the spacing of T-slot, according to stall bars conventional spread spacing setting, facilitates positioning strip spacing to adjust simultaneously.Can according to the actual quantity of stall bars and arrangement pitches, adjustment positioning strip quantity and spacing, easy to assembly.
Further, the telescopic end often organizing described hydraulic cylinder group is longitudinally fixed with flexible arc press strip.Hydraulic cylinder group can not destroy stall bars and soundboard structure when pressing down and making stall bars and soundboard glue together fixing.
Further, also heating plate is provided with between described mold base and arc module.Heater plate stall bars and soundboard viscose glue medium, make it accelerate solidification, enhance 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 the setting of heater plate monitoring temperature, and setting value load module and control signal output module control servomotor and hydraulic cylinder group is opened.
Beneficial effect of the present invention is:
By arranging the cover half device and die device that coordinate with soundboard, stall bars, help soundboard and stall bars to glue together rear arc to shape, by adjustment positioning strip quantity and spacing, coordinate actual quantity and the arrangement pitches of stall bars, uniform pressurization, makes soundboard stall bars fully be adhesively fixed, improves product quality, and cover half device is arranged heating plate quickening viscose glue media cures, thus enhance productivity.
