[0003] Authorized announcement number is that the Chinese patent of CN206106035U discloses a kind of high-efficiency bamboo material bending shaping mold, and its working principle is that the bamboo strips are pressed into a circle through the mutual cooperation of a cylindrical inner mold and a plurality of arc-shaped outer molds. Although the structure and method of pressing bamboo strips into a circle is extremely efficient, the defective rate of the pressed round bamboo strips is extremely high, and most of the round bamboo strips have cracks of varying degrees, which can only be covered up by later repairs Cracks affect its aesthetics and structural stability as a food box, and some round bamboo strips with large cracks are even scrapped directly, resulting in a serious waste of bamboo, which is not conducive to environmental protection

Embodiment 1

[0041] Please refer to figure 1 as well as figure 2 , a kind of anti-cracking bamboo strip 7 bending shaping device, comprising:

[0042] base 1;

[0043] Cylindrical mold 2, the cylindrical mold 2 is fixed on the base 1;

[0044] The first drive cylinder 3, the first drive cylinder 3 is an air cylinder, hydraulic cylinder or electric cylinder, preferably an air cylinder, the cylinder body of the first drive cylinder 3 is fixed on the base 1, and the cylinder body of the first drive cylinder 3 The piston rod is perpendicular to the axis of the cylindrical mold 2 and its axis is located in the same plane;

[0045] A clamping block 4, which is connected to the end of the piston rod of the first drive cylinder 3;

[0046] The bending assembly 5, two of the bending assemblies 5 are symmetrically arranged on both sides of the cylindrical mold 2 and the first drive cylinder 3, and the bending assembly 5 includes:

[0047] Screw guide rail mechanism 51, described screw guide ra...

Embodiment 2

[0058] The anti-cracking bamboo strip 7 pressure bending and shaping device described in embodiment 1, wherein, also includes: clamping and positioning mechanism 6, a plurality of said clamping and positioning mechanisms 6 are distributed in a circular array and arranged on the circular surface of cylindrical mold 2 Above, the clamping positioning mechanism 6 includes:

[0059] The third driving cylinder 61, the third driving cylinder 61 is an air cylinder, a hydraulic cylinder or an electric cylinder, preferably an air cylinder, and the cylinder body of the third driving cylinder 61 is hinged to the circular surface of the cylindrical mold 2;

[0060] L-shaped clamp 62, one end of the L-shaped clamp 62 is hinged on the circular surface of the cylindrical mold 2, and the right-angled side where the one end of the L-shaped clamp 62 is located is hinged to the piston rod end of the third drive cylinder 61 through a connecting piece department;

[0061] The circumferential surfa...

Embodiment 3

[0067] The anti-cracking device for bending and shaping bamboo strips 7 according to Embodiment 2, wherein an additional clamping and positioning mechanism 6 is provided on the side of the cylindrical mold 2 away from where the clamping block 4 is located.

[0068] Please refer to figure 1 , in the above structure, the additional clamping and positioning mechanism 6 is used for clamping and positioning the ends of the bamboo strips 7. When the bending of the bamboo strips 7 is completed, the two ends of the bamboo strips 7 can be accurately docked through the above-mentioned additional clamping and positioning mechanism 6. Thereby, the roundness of bending of the bamboo strip 7 is further ensured, and the machining accuracy is improved.

Abstract

The invention relates to the technical field of bamboo product processing equipment, in particular to an anti-cracking bamboo strip bending and shaping device and a method of the anti-cracking bamboo strip bending and shaping device. Through lead screw guide rail mechanisms on the two sides, a driving cylinder drives a pressing roller to be slowly attached to the circumferential face of a cylindrical mold from a positioning area in the middle of the bamboo strip to the two ends to conduct pressing forming on the bamboo strip step by step, although compared with the prior art, the efficiency is reduced, but compared with a pure manual manufacturing technology, the efficiency is still remarkably improved, and the production cost is reduced. Due to the fact that bamboo battens are bent through single-point gradual slow pressing forming, sufficient plastic deformation reaction time is obtained when the bamboo battens are bent, it is avoided that due to the fact that all parts of the bamboo battens are stressed and extruded at the same time, the bamboo battens crack, and the circular bamboo battens manufactured through the device and the method have the advantages of being high in roundness and free of cracking.

Description

technical field [0001] The invention relates to the technical field of bamboo product processing equipment, in particular to an anti-cracking device for bending and shaping bamboo strips and a method thereof. Background technique [0002] Bamboo is widely used in furniture and daily necessities due to its advantages of high hardness, good stability and short growth cycle. One of the uses of bamboo is to bend bamboo strips into a circle and use them as the frame of food boxes or tea boxes. Now In the prior art, the bending of the bamboo strips into a circle is usually accomplished through a bending die. [0003] Authorized announcement number is that the Chinese patent of CN206106035U discloses a kind of high-efficiency bamboo material bending shaping mold, and its working principle is that the bamboo strips are pressed into a circle through the mutual cooperation of a cylindrical inner mold and a plurality of arc-shaped outer molds. Although the structure and method of pres...
