Abstract

DC60 drum body manufacturing process by 3-layer stacking by stacking the middle wooden slats horizontally, forming the drum body. By cutting and slicing the wood into thin sheets They are of the same thickness and length as needed, with one piece cut off the top about 6 inches and the other slit across. Follow the wood grain, then take the slotted wood and apply epoxy hot glue Or urea glue All over the wide side Then overlap or interlock with a 6-inch cut-out piece with a transverse slit and glued over another layer. Then bring another piece of wood to overlap another layer Then enter the compressor and Bending through the heat at 150 degrees Celsius takes 15-30 minutes and then comes to trim the edge according to the degree, then drill holes on both sides, 2 holes on each side, with the same spacing of the wood again. The pieces were to shoot 2 nails at the edges of the 2 on each side, leaving about 15-20 mm in length, with the distance of the two being the same as the holes of the wood drilled as mentioned above. Then, apply hot glue, epoxy or urea glue over the side of the perforated piece, then cultivate it with glue and fire nails to form the drum. Then put in the oven to dry at 100 degrees Celsius, take about 1 hour for the glue and Wood that is completely dry or with a moisture content of not more than 5 percent for drum molding. The production process of the drum with 3 layers of wood by stacking the middle wooden slats horizontally, forming a drum body.

Claims (1)

1. The production process of the drum by stacking 3 layers of wood by stacking the middle wooden slats horizontally. The steps are as follows: - Take the wood to cut into the desired length and cut the slits along the length of the wood grain into a sheet with a thickness of 2 mm or more. - Take a piece of wood (1) and cut the end about 6 inches. 1 sheet and cut another wooden slit Crosswise grain To be approximately 6 inches wide and the same length as the width of the wood (1) - Take the cut, slit and slit and glue the front surface of the width with epoxy or urea glue. It can be used in both powder and liquid form, and the wood (1), the top cut, approximately 6 inches, is applied to the glued wood piece and the wood (2) is applied against the wood (1). ) On such glued wood pieces - epoxy hot glue Or urea glue Can be used both with powder and liquid on the wood (1), the top cut approximately 6 inches, and the wood (2) that comes into contact with the above (1) - take the cut, slit and slit again. The plate is joined to the width of the wood piece (1), the top cut off about 6 inches, and the wood (2) that comes into contact with the glued wood (1) - then Enter the compactor and bend the width of the wooden board tightly and heat it at 150 ° C for 15-30 minutes. - Take the stacked pieces of wood that have been bent and then cut. Edging by degrees to have a taper according to the arc of the drum. Then drill holes at the edge of the thickness on both sides of the two holes to a depth of 15-20 mm to the same distance. And another piece of wood was arranged to shoot a nail on the edge The thickness of both sides, two on each side, leaving nails protruding 15-20 mm long, where the distance of the nails must be the same as the holes above. - Apply glue to the sides at the thickness of the perforated wood. Start with hot glue, epoxy, or urea glue. Available in both powder and liquid types. Then placed and connected to the wood that was nailed. By having nails inserted into the holes of the said wood pieces, arranged alternately, and so on by degrees until the full circle. - To compress them into a round by using a round ring plate sized as the size of each drum. By entering the number of three rings Then use a hydraulic jack to press the steel rings together tightly In the longitudinal side of the drum Then put in the oven to dry at a temperature of 100 degrees Celsius takes about 1 hour for the wood and glue to dry completely or have no more than 5 percent moisture. - The dried wood to be machined, peeled, smooth and have a shape. drum There is a unique The process of manufacturing the drum body is made of three layers of wood, by overlapping the intermediate planks in such a way that the second layer consists of a piece of wood (1), a piece of about 6 inches cut off the top. Wood (1) epoxy hot glue Or urea glue Available in both powder and type. Water all over the wide side, and place the wood (2) against the wood (1) the top cut approximately 6 inches across the grain on the wood (1) hot-glued. Poxy Or urea glue Can be used in both powder and liquid types. And apply epoxy hot glue Or urea glue Use both powder and liquid to fill the remaining width of the wood (1) and the wood (2), then take another piece of wood (1) to overlap the wood (1) the top cut off. These 6 inches and pieces of wood (2), for a total of three layers.
