As shown in fig. 1 to 4, a method for shaping a braid according to an embodiment includes: s10 grooves the first end of the webbing 10. S20 heats the first end of the webbing 10 of step S10. S30, performing preliminary shaping on the woven belt 10 in the step S20. S40, the preliminary set webbing 10 of step S30 is set.

By applying the technical scheme of the embodiment, the first end of the braiding belt 10 is heated by processing the groove on the first end of the braiding belt 10, the heated first end is easy to realize preliminary shaping, and the braiding belt 10 is shaped after preliminary shaping. Such an operation step is not affected by the strength of a worker or factors of a machine to cause a large difference, and the braid 10 is shaped neatly and with high accuracy. The technical scheme of the application effectively solves the problem that the braid in the prior art cannot realize accurate shaping.

As shown in fig. 2 to 4, in the technical solution of the present embodiment, the preliminary shaping in step S30 is to bend the portions on both sides of the groove inwards. The braid 10 is grooved so that the edges on both sides of the groove are bent inward, and the groove forms a relief portion. The thickness of the braid 10 is kept unchanged when the edges on both sides of the groove are bent inward.

As shown in fig. 2, in the technical solution of the present embodiment, the braid 10 is put into the mold 20 for shaping when the braid 10 is initially shaped. The braiding belt 10 is shaped through the die 20, so that the product (the braiding belt 10) is manufactured in a standard and tidy manner, and the processed product is not different due to the fact that the experience, the strength and other factors of operators are different.

As shown in fig. 2 to 4, in the technical solution of the present embodiment, the mold 20 includes a mold body 21 and a clamp 22, the mold body 21 has a braid placing groove 211, one end of the braid placing groove 211 has an opening, and a middle portion of the braid placing groove 211 has a through hole 212 matched with the clamp 22. The arrangement of the through holes 212 facilitates the installation of the clamp 22, and the braid 10 is fixed by the clamp 22, so that the braid 10 is processed more accurately, and dislocation and other phenomena are not easy to occur.

In the solution of the present embodiment (not shown in the figure), the heating is performed by steam in step S20. The steam heating mode is easy to control, and the steam heating process is controllable and not easy to damage the braiding belt 10. In the technical scheme of the embodiment, the steam heating needs to be pressurized between 10Kg and 19Kg, and the temperature of the steam heating is 130 ℃ to 170 ℃ and the pressure maintaining time is 60S.

In the technical solution of the present embodiment (not shown in the figures), the braid 10 is cold-pressed after being heated and bent by steam. The cold pressing time is between 50S and 90S, and the cold pressing temperature is between 3 ℃ and 18 ℃. After steam heating, the braiding belt 10 subjected to cooling is good in shaping effect, and the problem that the resilience of the braiding belt 10 after preliminary shaping is large is difficult to occur.

In the technical solution of the present embodiment, in step S40, the shaping is performed by means of bonding shaping. The woven belt 10 after the shaping does not rebound, and the woven belt 10 shaped by the method does not rebound due to the action of adhesive force. It should be noted that, according to the processing requirement, the braid 10 may be fixed with other objects before bonding, and the braid 10 may be bonded with other objects at this time, which not only has the shaping function, but also has the bonding function with other objects.

As shown in fig. 2, in the technical solution of this embodiment, the bonding and shaping includes bonding the adhesive film at the bending gap of the woven belt 10, and placing the heating block 30 at the adhesive film position, where the adhesive film is activated by heating to achieve bonding and shaping. The heating and activating of the heating block 30 ensures that the bonding mode is firm, and the problem of sanitation caused by glue running is not easy to occur.

In the technical solution of this embodiment (not shown in the figure), cold pressing is also required after the adhesive film is melt-bonded. After cold pressing, the braid 10 is better bonded and cured. The characteristics of the adhesive and the woven belt 10 are fully utilized, plastic deformation is easy at high temperature, and after the temperature is reduced, the curing effect is good, and deformation is not easy. The cold pressing temperature is between 3 ℃ and 18 ℃, the cold pressing time is between 8S and 70S, and the cold pressing pressure is kept between 12Kg and 13 Kg.

In the technical solution of this embodiment, the groove at the first end of the braid 10 is rectangular, and the bending avoidance groove is machined at the two corners of the rectangle near the second end of the braid 10. Rectangular groove processing is convenient, machining efficiency is higher, and the setting of groove is dodged in the buckling makes braid 10 be difficult to appear piling up the phenomenon when buckling.

In the technical solution of the present embodiment, the auxiliary pressing block (pressing block 40) is further included, and before the heating block 30 heats, the braid 10 and the mold main body 21 need to be pressed by the auxiliary pressing block. It should be noted that, the auxiliary pressing block is made of non-heat-conductive material (similar to synthetic stone, peek block, etc.), the bottom is made of saw-tooth or wave-like protrusions (patches can be used), and the protruding surface of the pressing block 40 protrudes slightly from the bottom of the heating block, so as to increase the fixing capability of the flexible object.

As described above, the braid 10 of the present embodiment is made of plastic or flexible material, and is applied to electronic products worn by wrist-watch bands, wrist-bands, and the like. During manufacturing, firstly, a bendable pattern (not limited to a rectangle) is cut according to the final pattern to be shaped, and in order to ensure that the arcs at two sides always keep the original material characteristics, rectangular-like openings are cut (sharp corners or saw teeth can be added at corners to reduce bending resistance). Then, the flexible product (the woven belt 10) is fixed by using the clamping blocks (the clamp 22), the positioning standard is transferred from the flexible woven fabric to the hard clamping blocks, the hardness of the clamp 22 is higher than that of the woven belt 10, and the positioning is easy. Then, the heating block 30 is used for primarily heating the required processing area, and the arc shape can be reserved at normal temperature for forming, so that the post station operation is convenient. By steam reforming, the flexibility of the braiding outside the heated area and all the steam-receiving area surfaces can be restored. All heated areas of the product are subjected to steam treatment, and the size of the steam area can be adjusted for the flexible braided fabric according to preliminary hot pressing. Finally, the adhesive film is adhered to the gap generated by bending (the size of the adhesive film is determined according to the cutting shape and the size of the gap after bending), the heating block 30 is used for heating and activating the required area (the activatable temperature of the adhesive film is adjusted according to different materials), finally, the heating temperature is possibly higher than the maximum bearing temperature of the flexible braiding article, the melting is generated, and the cooling treatment (usually cooling to room temperature and according to various conditions) is needed after the heating

The technical scheme of this application is for solving flexible material shaping and shaping design, on the tensile nature that flexible establishment material itself possessed, can the resilient benchmark, remains required partial flexible material own characteristic, only changes the material characteristic in little regional, reaches the shaping effect of preferred shaping.
