Abstract

The present invention relates to improvement for the glue formation technology of a key component of the panel tone beams of the existing guitar product. The improved technology has a key point that the technology adopts a high frequency press, and the following technology characteristics are formed: (1) the tone beam is pressurized by means of independently adjusted hydraulic ram in the procedures of gluing and solidification formation; (2) pressurizing adhesion is realized in a high frequency electric field induction heating mode in the procedures of gluing and solidification formation, and medium heat is implemented to glue surfaces between the panel tone beams simultaneously.

Description

Guitar front panel tone beam high-frequency adhesion and formation technique

Technical field

The present invention is the improvement to the critical component panel tone beam gummed setting process of existing guitar product.

Background technology

The typing of guitar panel tone beam gummed is one critical process that is related to the guitar quality.This procedure is the audio amplifier upper and lower panel with guitar, is called for short panel, and splicing is processed as after certain plane geometric shape, with pre-processed sound balk bar pressurization and be bonded together, solidifies rear board and is fixed to the curved surface shape that designs.Be after every being ready to complete such as processing typing of assembly unit moulding, sound balk bar in the existing processing technology at flat panel, between sound balk bar and flat panel gluing, then to adopting Steam Heating in the pressurization of sound balk bar, the pressurization or taking the typing of nature cooling curing.Because the complexity of panel forming rear curved surface, only the typing cemented surface by middle Jie's mould transmission pressure and sound balk bar is difficult to accomplish that whole attached realities are even, so the processing adjustment process of high-quality product is very long and difficult, operational process of craft is complicated and lack standard, and the dimension one that " experience " becomes product quality guarantees it is the management philosophy that does not meet modern enterprise.It is cool in the uneven outer heat that Steam Heating is heated the glue face, spontaneous curing not only the time oversize, and can form the quality that soft core directly influences panel.

Summary of the invention

The objective of the invention is guitar conventional machining process and pressurization, heating special tooling are improved the electromagnetic field of high frequency heating and the high-quality bonding and curing operation of fluid head drive pressurization means realization that adopt the high frequency press to provide.

Key of the present invention is to have adopted the high frequency press in guitar panel tone beam gummed setting process, thereby has realized that hydraulic cylinder is independently adjusted and evenly pressurize and realized quick curing by means of high-frequency dielectric mode of heating from inside to outside.Following characteristics on processing technology, have been formed: 1. by the hydraulic jack of independently adjusting the sound beam is pressurizeed in gummed and the solidifying and setting operation, 2. realize the medium of glue face is heated and solidifies by the high-frequency electric field induction heating mode in gummed and the solidifying and setting operation.

The good effect of above process characteristic is: can effectively guarantee attached real, the pressurization of each root sound beam and combining of panel evenly, form technical specification easily and guarantee the product quality produced in batches.Be heated evenly inside and outside the glue face, curing rate improves hundred times, and solidifies thoroughly, firmly, and quality is significantly improved than traditional handicraft.

Above technology can make each root sound beam bar and soundboard uniform-compression, inside and outside thermally equivalent under the support of above-mentioned high frequency press and supporting special-purpose comb electrode, realize high-quality gummed typing.

Further specify below in conjunction with accompanying drawing and the objective of the invention is how to realize.

Description of drawings

Fig. 1 is the structure and the processing technology schematic diagram of top panel and the typing of sound balk bar gummed.

Fig. 2 is the structure and the processing technology schematic diagram of lower panel and the typing of sound balk bar gummed.

Wherein 1A is the top panel of Guitar voice box, 1B is the lower panel of Guitar voice box, and 2 is the sound beam, and 3 for being connected to high frequency press medium-high frequency power output end ground positive electrode, 4 for being connected to high frequency press medium-high frequency power output end ground negative electrode, and 5 represent independent hydraulic cylinder of adjusting and the fluid head that is driven.

The specific embodiment

Improved key to traditional handicraft is to introduce the high frequency press, to adapt to new processing technology.Comprise gluing, compression set and each procedure of solidifying and setting between processing typing, sound beam 2 and the upper and lower panel of plane geometric shape assembly unit moulding, sound beam 2 of upper and lower panel in the technology process after the improvement.Adopted the high frequency press in the technology after the improvement and formed following technology characteristics: 1. in gummed and the solidifying and setting operation by independent 5 pairs of sound beams of hydraulic jack of adjusting 2 pressurizations, 2. in gummed and the solidifying and setting operation by high-frequency electric field induction heating mode realization pressurized adhesion the time medium that carries out to the glue face heat.Owing to adopted 5 pairs of sound beams of hydraulic jack, 2 pressurizations of independent adjustment, just might form and adapt to that row is adjusted and the final technological operation standard of producing in batches that forms, and guarantee the uniformity of product quality at the difference of the sound beam of the different body characteristicses of different model guitars or same model and positions of panels of living in.Therefore, the present invention is the key that the guitar manufacturing industry enters modern management to the above improvement in the bonding setting process of guitar panel tone beam.It not only makes the production efficiency of guitar critical component improve hundreds of times, and the causing property of product quality has had the support of normalization process.In order to form the adaptability of technology, the described independent hydraulic jack of adjusting 5 is pressed the corresponding distribution of quantity and position of sound beam 2.The heating electrode (3,4) that high frequency electric source output in the high frequency press described in the above technology is drawn is that positive and negative alternate even distribution forms comb electrode.Comb electrode is wide by 2-10mm, the thick copper coin of 5-30mm is processed into operating frequency 10-50 megahertz.Comb electrode the enough covering envelope whole front panel of area, the distribution of positive and negative electrode in the comb electrode (3,4) is adjustable at interval mates with panel, the corresponding design of sound beam.
