Description

A method for repairing balsa wood TECHNICAL FIELD

[0001] The present application relates to the technical field of wood processing and repairing, and particularly relates to a repairing method for a damaged part of balsa wood. BACKGROUND

[0002] Balsa wood, as a kind of light wood, is widely used in many fields such as building, furniture and handicraft manufacturing. However, due to its material characteristics, balsa wood is prone to damage during use, which not only affects its service life, but also reduces its aesthetic appearance.

[0003] Traditional balsa wood repairing methods usually involve the following steps: first, a hole is drilled in the damaged part to ensure that the area of the hole completely covers the entire damaged part; then, a repairing plug is inserted into the hole. In order to enhance the bonding force between the repairing plug and the balsa wood, glue is usually applied to the outer surface of the repairing plug. However, this method has many problems in actual operation. First, when the repairing plug with glue on the outer wall is inserted into the hole, the glue is easily scraped out of the hole, resulting in uneven distribution of the glue and greatly reducing the repairing effect. Secondly, due to the low utilization rate of glue, not only the repairing cost is increased, but also the outer surface of the balsa wood may be contaminated by excessive glue, further affecting the aesthetic appearance after repairing. SUMMARY

[0004] The present application aims to provide a repairing method that can save the step of applying glue, improve the uniformity of glue distribution and effectively improve the utilization rate of glue. Through optimization of the repairing steps and structural design, the present application seeks to achieve a more efficient, aesthetic and practical balsa wood repairing effect.

[0005] The above technical purpose of the present application is achieved by the following technical scheme: a balsa wood repairing method, comprising the following steps:

[0006] Drilling a hole in the damaged part of the balsa wood, the area of the hole completely covering the entire damaged part;

[0007] Using balsa wood as raw material to make an upper repairing plug and a lower repairing plug, the upper repairing plug being composed of a clamping part and a plug-in part, the clamping part being in the shape of a circular truncated cone, the plug-in part being in the shape of a circular cylinder, and the plug-in part being connected to the end of the clamping part with smaller outer diameter, the lower repairing plug being in the shape of a circular truncated cone, and the end of the lower repairing plug with smaller outer diameter being provided with a receiving groove;

[0008] Filling the receiving groove with glue, and inserting the lower repairing plug into the hole from the bottom to the top, and then inserting the upper repairing plug into the hole from the top to the bottom, until the plug-in part is inserted into the deepest part of the receiving groove, and the glue is squeezed into the gap between the outer side wall of the upper repairing plug and the lower repairing plug and the inner side wall of the hole;

[0009] After the glue solidifies, the excess part of the upper repair plug and the lower repair plug protruding out of the surface of the balsa wood is sawed off.

[0010] In some embodiments, before the hole is drilled at the damaged part of the balsa wood, a drilling contour line is drawn around the damaged part.

[0011] In some embodiments, the edge of the opening end of the accommodating groove is chamfered.

[0012] In some embodiments, the plug-in part is threadedly matched with the accommodating groove.

[0013] In some embodiments, after the upper repair plug and the lower repair plug are both installed in place, the whole balsa wood is rotated or shaken.

[0014] In some embodiments, during the drilling of the hole, a dust suction device is used to continuously suck dust around the hole.

[0015] In some embodiments, after the excess part of the upper repair plug and the lower repair plug protruding out of the surface of the balsa wood is sawed off, the cut surface of the upper repair plug and the lower repair plug is polished.

[0016] Compared with the prior art, the present application has the following advantages:

[0017] In the traditional repair method, the glue is easy to be scraped out of the hole, resulting in uneven distribution and low utilization. The present application utilizes the sealed annular cavity formed between the upper repair plug, the lower repair plug and the inner wall of the hole to ensure that the glue can quickly and uniformly fill the whole cavity after being squeezed out, thereby improving the uniformity and utilization of the glue and enhancing the firmness of the repair.

[0018] The present application simplifies the repair process and improves the repair efficiency by eliminating the step of applying glue on the outer surface of the repair plug through unique structural design. The operator does not need to worry about uneven or excessive glue application, making the repair process more convenient. Since the glue is completely confined in the sealed annular cavity in the present application and cannot overflow, the pollution of the balsa wood surface by the glue is effectively avoided, and the appearance after repair is maintained.

[0029] As shown in Figures 1-5, the present embodiment provides a balsa wood repair method for repairing the damaged part 2 on the balsa wood 1, comprising the following steps:

[0030] A hole 4 is formed at the damaged part 2 of the balsa wood 1, and the area of the hole 4 needs to completely cover the entire damaged part 2 to ensure the repair effect;

[0031] An upper repair plug 5 and a lower repair plug 6 are made of the barsha wood 1, both of which are made of the barsha wood 1 and have good compatibility and combination, wherein the upper repair plug 5 is composed of a clamping part 501 and a plug-in part 502 which are connected by an integral coaxial center, the clamping part 501 is in a circular truncated cone structure, the plug-in part 502 is in a cylindrical structure, the outer diameter of the plug-in part 502 is equal to the outer diameter of the smaller end of the clamping part 501, and the plug-in part 502 is connected to the smaller end of the clamping part 501, the smaller end of the clamping part 501 can extend into the hole 4, but the other end cannot extend into the hole 4, and after the smaller end of the clamping part 501 extends into the hole 4, there is a gap between the outer side wall of the clamping part 501 and the plug-in part 502 and the inner side wall of the hole 4;

[0032] The lower repair plug 6 is in a circular truncated cone structure, the smaller end of which can extend into the hole 4, and the other end cannot extend into the hole 4, and after the smaller end of the lower repair plug 6 extends into the hole 4, a gap will be left between the outer side wall of the lower repair plug 6 and the inner side wall of the hole 4, and the smaller end of the lower repair plug 6 is provided with a receiving groove 601, the inner diameter of which is greater than or equal to the outer diameter of the plug-in part 502, and the two are plug-in matched;

[0033] The receiving groove 601 is filled with glue 7, and the end of the lower repair plug 6 provided with the receiving groove 601 is inserted into the hole 4 from the bottom, and the end of the upper repair plug 5 provided with the plug-in part 502 is inserted into the hole 4 from the top, until the plug-in part 502 is inserted to the deepest part of the receiving groove 601, during which the glue 7 in the receiving groove 601 is squeezed out into the gap between the outer side wall of the upper repair plug 5 and the lower repair plug 6 and the inner side wall of the hole 4, and since a sealed annular cavity is formed between the upper repair plug 5 and the lower repair plug 6 and the inner wall of the hole 4, the glue 7 can quickly fill the annular cavity after being squeezed out, and there is no situation of glue 7 overflowing outward;

[0034] After the glue 7 solidifies, the excess part of the upper repair plug 5 and the lower repair plug 6 protruding out of the surface of the barsha wood 1 is sawn off, so as to complete the repair of the barsha wood 1, at this time, the upper repair plug 5 and the lower repair plug 6 have been firmly combined with the barsha wood 1, and the effective repair of the damaged part 2 is realized.

[0035] The upper repair plug 5 and the lower repair plug 6 are respectively inserted into the two ends of the hole 4, and a sealed annular cavity is formed between the two and the inner wall of the hole 4. The extrusion process of the glue 7 is also entirely in the sealed annular cavity, and there is no case of glue 7 overflowing outward. The glue 7 has fluidity before solidification, so after being extruded from the containing groove 601, it can quickly fill the annular cavity because of its fluidity. This can save the process of coating the outer surface of the repair plug with glue. The traditional method of coating the outer surface of the repair plug with glue is very easy to scratch the glue 7 on the outer surface of the repair plug to the outside of the hole 4 when the repair plug is inserted into the hole 4. On the one hand, it leads to uneven distribution of the glue 7 on the outer surface of the repair plug, and on the other hand, the utilization rate of the glue 7 is also low. Moreover, the extruded glue 7 is also easy to pollute the outer surface of the balsa wood 1. Therefore, the application can improve the uniformity of the glue 7 distribution while saving the gluing step, and also effectively improve the utilization rate of the glue 7.

[0036] In some embodiments, as shown in FIG. 1, before the hole 4 is opened at the damaged part 2 of the balsa wood 1, a drilling contour line 3 is drawn around the damaged part 2. By drawing the drilling contour line 3 around the damaged part 2 in advance, it can be ensured that the subsequently opened hole 4 can accurately cover the entire damaged part 2, avoiding poor repair effect caused by position deviation or improper size of the hole 4. At the same time, drawing the drilling contour line 3 can also help the operator better master the shape and size of the hole 4, so as to more accurately perform the repair operation and improve the accuracy and efficiency of the repair.

[0037] In some embodiments, as shown in FIGS. 2-3, the edge of the opening end of the containing groove 601 is chamfered. By chamfering the edge of the opening end of the containing groove 601, the insertion of the plug-in part 502 into the containing groove 601 can be smoother, reducing the friction and resistance between the plug-in part 502 and the edge of the containing groove 601, so as to ensure that the plug-in part 502 can be smoothly and tightly inserted into the containing groove 601, improving the stability and effect of the repair. At the same time, chamfering can also prevent the plug-in part 502 from damaging or deforming the edge of the containing groove 601 during insertion, further ensuring the quality and reliability of the repair.

[0038] In some embodiments, the plug-in part 502 is threadedly connected with the containing groove 601. By designing the thread connection between the plug-in part 502 and the containing groove 601, the plug-in part 502 can be more tightly combined with the inner wall of the containing groove 601 during insertion, thereby further enhancing the bonding force and stability between the repair plug and the balsa wood 1. In addition, the design of thread connection can also make the repair plug more convenient and fast during insertion and fixation, improving the efficiency and convenience of the repair operation.

[0039] In some embodiments, after the upper patch plug 5 and the lower patch plug 6 are both installed in place, the entire piece of balsa wood 1 is rotated or shaken, which further promotes the even distribution of the glue 7 within the annular cavity, ensuring that the glue 7 can fully fill the gap between the patch plugs and the inner wall of the hole 4, thereby improving the sealing and firmness of the repair.

[0040] In some embodiments, during the process of creating the hole 4, a dust suction device is used to continuously perform dust suction operations around the hole 4. Through the use of the dust suction device, the wood chips and dust generated during the drilling process can be effectively sucked away, preventing these impurities from entering the inside of the hole 4 or adhering to the surroundings of the hole 4, thereby affecting the repair effect and the adhesion of the glue 7. At the same time, the dust suction operation can also keep the working environment clean, improving the comfort and efficiency of the repair operation. In addition, timely removal of wood chips and dust can also reduce the burden of subsequent cleaning work, making the repair process smoother and more efficient.

[0041] In some embodiments, after the excess part of the upper patch plug 5 and the lower patch plug 6 protruding beyond the surface of the balsa wood 1 is sawn off, the cut surface of the upper patch plug 5 and the lower patch plug 6 is polished. By polishing the cut surface, burrs and uneven parts generated by sawing can be removed, making the surface of the repaired balsa wood 1 smoother and more even, improving the appearance and quality of the repair. In addition, polishing can also make the repaired part and the surrounding un-repaired balsa wood 1 surface transition more naturally, reducing the visual sense of strangeness and improving the overall aesthetic effect.

[0042] The specific embodiments are merely an explanation of the present application, which is not a limitation of the present application. Those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, as long as the modifications are within the scope of the claims of the present application.
