Description

A kind of drum head tensioner general device with step-less adjustment function
Technical field
The present invention relates to instrument recognition fields, lead in particular to a kind of drum head tensioner with step-less adjustment function With type device.
Background technology
The height of big drum tone is related with the frequency of vibration, and frequency is higher, and tone is higher;Loudness is the width vibrated by sound source What degree determined, amplitude is bigger, and loudness is bigger;When beating a drum, drum head stretches tight tighter, and vibration frequency is faster, and the tone of sound is higher, The strength beaten a drum is bigger, and the loudness of drum head is bigger, and sound is louder.The manufacture craft of its big drum:1st, sorting, blanking.2nd, solve Clappers.It according to different drum, is cut on the lower blank into small powder, then stacks drying.3rd, baking sheet.The drum parched will be dried Plate is neatly inserted in oven, continues to dry.4th, drum is done.The dry plate come out of the stove subtly is composed to the blank of drum on request, Without crack, circle wants standard.5th, neat accent, scrapes Cavity surface.Accent is smooth, and Cavity surface is smooth.6th, epithelium.The ox-hide soaked is covered It in ready-made drum, is tightened with drawstring, confirms that the dynamics of ox-hide has reached vertex, then bulging nail is nailed on after air-drying drying.7th, polishing, on Paint.Further to Cavity surface polishing, polishing, paint processing is finally carried out.
Drum is carried out can be carried out " epithelium " by the sanding and polishing of machine, and the ox-hide handled well is covered in ready-made drum On frame.This link to drum covering is all that woman worker is doing, more resistant to the heart and careful.The drum of covering is waited to be placed on the steelframe of speciality On, then worker by the ox-hide cut out cover on drum, leather week makes a circle tightened with rope after tie up on steelframe.It ties up followed by Drum is jacked up with the jack placed under drum body again, drum head is then stretched even tauter.Next woman workers will also climb to big drum On, it rhythmically steps on to step on drum head, here it is the important ring " stepping on skin " made in legend in drum, in order that allowing drum head Tension is evenly.Also drum body is up pushed up again with jack in fact, is then followed by stepping on again, and so on several times, covering Link just calculate completion, be also muscular labor except being particular about technology and experience, when the dynamics that drum head is tightened reach vertex, follow closely Last batch putty, japanning link are can be carried out after upper drum nail is fixed.
When ox-hide drum is to rainy day or wet weather, surface is just loose, is not tighten to lead due to drum head It causes, it is necessary to control drum head level of tightness and dynamics from beginning of production.During existing system drum woman worker is needed frequently to climb to drum Upper " stepping on skin ", consumes one's strength, climbs upper low, be absolutely unsafe, and also " stepping on skin " dynamics is uneven, and density degree is difficult to control, and is made It cannot effective swelling into follow-up drum head.
