Description
Technical field:
The present invention relates to piano manufacturing field, in particular to a kind of piano soundboard stall bars gluing shaping equipment.
Background technique:
Piano soundboard is made of components such as sounding board, stall bars, crown cut, soundboard frames.Sound is set to have continuity, soundboard is necessary
It is swelled in cambered surface.Its concave surface is stained with stall bars, and convex surface is equipped with crown cut.
Stall bars are the indispensable component parts of soundboard, it bears biggish tensile stress, the design of stall bars both ends in soundboard
At oblique diamond shape, the arc of pico- protrusion is designed to the bonding plane of sounding board.
Stall bars can reinforce the intensity of sounding board, resist the pressure from crown cut.Due to sound wave in wood along annual ring and
Spread speed when crossing annual ring is different, and acoustic vibration is passed to along annual ring direction by any point on crown cut than passing to
It is fast to cross annual ring direction.Therefore, annual ring direction is crossed on soundboard will be bonded stall bars, its gluing vertical with sounding board makes sound
Wave is propagated from excitation point along crown cut, and when encountering the stall bars for crossing annual ring, sound wave is just rapidly transmitted to sound wave along stall bars whole
Block soundboard makes the whole sufficiently vibration of soundboard.
Securely, the loss to soundboard vibrational energy is reduced improves soundboard vibration ability, reduces sound for soundboard and stall bars cooperation
Decay significant.The sizing of traditional soundboard stall bars gluing, be pre-processed soundboard and stall bars item are applied into glue bond, then
It is pressurizeed, is solidified using clampings such as fixture, fixtures, sizing, this gluing mode is easily destroyed soundboard and the original arcuate structure of stall bars,
And pressurization is unevenly easy to cause stall bars to come unglued, and influences the sound equipment and bearing capacity of soundboard.
Summary of the invention:
The present invention provides a kind of piano soundboard stall bars gluing shaping equipment, solves and above-mentioned be easily destroyed soundboard stall bars knot
Structure, stall bars are easy to come unglued, and influence the sound equipment and bearing capacity of soundboard.
Technology solution of the invention is as follows: a kind of piano soundboard stall bars gluing shaping equipment comprising organic frame, Gu
It is scheduled on the cover half device of rack lower end, rack-mounted die device, and drives the liter of the die device vertical lifting
Falling unit, the cover half device includes mold base, and the mold base upper end is equipped with arc module；The die device
It include lower platen, the lower platen lower end surface is uniformly provided with multiple T-slots extended longitudinally, is inserted in the T-slot
I-shaped positioning strip, the positioning strip lower end surface are fixed with hydraulic cylinder group.
Further, the lifting device includes the top plate for being fixed on the rack end, the top plate and mold base it
Between two sides be separately installed with screw lifting device, the screw lifting device includes support base, lead screw, screw slider, described
Fixed on the outside of screw slider and lower platen, the lead screw upper end is connected with servo motor, and the servo motor is fixed on top plate
End.Screw lifting device is driven using servo motor, lifting is stablized, convenient for control.
Further, the spacing of the T-slot is 30mm ~ 45mm, and the quantity of the positioning strip is 9 ~ 17.The number of stall bars
The size certainly with sounding board is measured, small upright piano to big grand piano, which is 9 ~ 17, to be differed, and the quantity of positioning strip is according to stall bars
Conventional amounts setting；The arrangement spacing of stall bars is 90mm ~ 140mm, and treble is closeer, and bass area is relatively dredged, the spacing of T-slot according to
The setting of stall bars conventional spread spacing, while facilitating positioning stripe pitch adjustment.It can be adjusted according to the actual quantity and arrangement spacing of stall bars
Whole positioning strip quantity and spacing, it is easy to assembly.
Further, it is fixed with flexible arc press strip along longitudinal direction on the telescopic end of hydraulic cylinder group described in every group.Hydraulic cylinder group
Stall bars and soundboard structure will not be destroyed when pushing makes stall bars and soundboard gluing is fixed.
Further, heating plate is additionally provided between the mold base and arc module.Heater plate stall bars and soundboard
Viscose glue medium makes it accelerate solidification, improves production efficiency.
Further, the hydraulic cylinder group, servo motor and heating plate are connected with control system.
Control system includes temperature monitoring module, setting value input module and control signal output module, monitoring temperature
Module and setting value input module set heater plate monitoring temperature, setting value input module and control signal output module
It controls servo motor and hydraulic cylinder group is opened.
The beneficial effects of the present invention are:
By the way that the cover half device and die device that cooperate with soundboard, stall bars is arranged, soundboard and stall bars gluing rear arc are helped
Sizing cooperates the actual quantity of stall bars and arrangement spacing, uniform pressurization to make soundboard rib by adjusting positioning strip quantity and spacing
Wood is sufficiently adhesively fixed, and improves product quality, and heating plate is arranged on cover half device and accelerates viscose glue media cures, to improve
Production efficiency.
