[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] like Figures 1 to 2 The figure shows a bending jig. Its main structure includes a base plate 1, a clamping structure for securing the material, and a bending structure for bending the material. The base plate 1 can be fixed to a workbench or other location using fasteners such as bolts, making it convenient for operators to operate. The clamping structure is used to clamp the material, such as a strip of aluminum frame, and then the bending structure bends the material to the desired angle.
[0020] Specifically, the bending structure in this embodiment includes a limit plate 2, a swing handle 31 (i.e., an operating handle) and a bending pressure block 32. Among them, the limit plate 2 can be fixedly connected to the base plate 1 by bolts, and the swing handle 31 is arranged on one side of the limit plate 2 and is rotatably connected to the base plate 1 through a rotating shaft. Then, a bending pressure block 32 is arranged on the side of the swing handle 31 facing the limit plate 2, and a limit surface 21 is arranged on one side of the limit plate 2. The limit surface 21 is located at the upper part of the clamping structure, and the angle formed with the position of the clamped material provides space for the angle at which the material needs to be bent. Therefore, the limit surface 21 is preferably an inclined surface, and is inclined in the direction away from the bending pressure block 32. When the bending pressure block 32 does not change, the inclination angle of the limit surface 21 determines the maximum bending angle that can be achieved in this embodiment. Therefore, a bending interval is formed between the side of the bending pressure block 32 facing the limiter and the limit surface 21.
[0021] As a preferred embodiment, the bending surface of the bending block 32 can be parallel to the limiting surface 21 when the set bending angle is reached, so as to avoid indentations on the material at the angle of the bending block 32. The spacing of this interval is also the thickness of the material.
[0022] Among them, the material clamping plate 51 is located on one side of the limiting plate 2, and forms a clamping channel for the material to pass through between the material clamping plate 51 and the limiting plate 2. The distance between the material clamping plate 51 and the limiting plate 2 is set according to the width of the material and can be adjusted according to the thickness of different materials.
[0023] The bending pressure block 32 and the limiting plate 2 are both provided with a strip hole 5. The strip hole 5 on the bending pressure block 32 is detachably fixedly connected to the swing handle 31 by passing a bolt, and the bolt is threadedly connected to the swing handle 31; the strip hole 5 on the limiting plate 2 is detachably fixedly connected to the base plate 1 by passing a bolt, and the bolt is threadedly connected to the base plate 1. The design of the strip hole 5 allows the bending pressure block 32 to be displaced relative to the swing handle 31 or the limiting plate 2 by loosening the corresponding bolt, thereby facilitating the adjustment of the distance between itself and the limiting surface 21; and facilitating the material clamping plate 51 to adjust the distance from the limiting plate 2, thereby achieving clamping or limiting of materials of different thicknesses. At the same time, according to the different bending angle requirements of different materials, the distance between the bending pressure block 32 and the limiting plate 2 can also be adjusted through the strip hole 5, thereby improving the practicality of this embodiment.
[0024] The stopper 52 is located on one side of the base plate 1 and can be fixed to the base plate 1 via fasteners. The stopper 52 is provided with at least two first adjustment bolts 53 for abutting the material clamping plate 51. The first adjustment bolts 53 are threadedly connected to the stopper 52. The ends of the first adjustment bolts 53 abut the stopper 52, preventing the stopper 52 from shifting due to the presence of the strip hole 5 or the reverse force during the bending process, thereby improving the reliability of this embodiment. Two or more first adjustment bolts 53 can improve the stability of the support stopper 52. Similarly, in this embodiment, a positioning block 33 is fixedly connected to the swing handle 31. The positioning block 33 is provided with a second adjustment bolt 34 for abutting the bending pressure block 32. The second adjustment bolt 34 is threadedly connected to the positioning block 33. The ends of the second adjustment bolt 34 abut the bending pressure block 32, preventing the bending pressure block 32 from shifting due to the presence of the strip hole 5 or the reverse force during the bending process.
[0025] In this embodiment, the connection position between the swing handle 31 and the base plate 1 is on one side of the clamping channel. The swing handle 31 is located at the bottom of the base plate 1. The swing handle 31 is provided with a limit groove 35. The limit groove 35 is located on the side of the positioning block 33 facing the limit plate 2. The bending pressure block 32 is designed to be an "L"-shaped structure. The part of the bending pressure block 32 used to contact the material is on the bottom surface, and the part connected to the swing handle 31 is embedded in the limit groove 35 to save space. In addition, the limit groove 35 also needs to reserve space for adjusting the distance between the bending pressure block 32 and the limit surface 21. The side walls of the limit groove 35 reinforce the bending pressure block 32 to avoid displacement during the bending process of the material and to avoid collision between the bending pressure block 32 and the material clamping plate 51 during the rotation of the swing handle 31 (therefore, the material clamping plate 51 is provided with an inclined surface on the side of the bending pressure block 32, and the corner of the base plate 1 on the side of the material clamping plate 51 facing the bending pressure block 32 is designed to be rounded). When the swing handle 31 is rotated to be perpendicular to the clamping channel, one end of the material can pass through the clamping channel and extend to the upper part of the bending block 32 (the length of the extended material can be measured separately according to product requirements, or marked in advance, which will not be repeated in this embodiment), so that during the rotation of the swing handle 31, the material can be pushed to the limit surface 21 through the bending block 32 to achieve bending.
[0026] The working process of this embodiment is:
[0027] 1. Adjust the spacing of the clamping channels according to the material thickness;
[0028] 2. Adjust the distance between the bending block 32 and the limiting surface 21 according to the angle required by the product;
[0029] 3. Turn the swing handle 31 to a position perpendicular to the clamping channel;
[0030] 4. Insert the material into the clamping channel and extend the material out of the clamping channel toward one end of the bending structure;
[0031] 5. Rotate the swing handle 31. During the rotation of the swing handle 31, the material bends at the corner between the clamping channel and the limiting surface 21;
[0032] 6. Turn the swing handle 31 to a position parallel to the clamping channel and press the material. At this time, the material reaches the required bending angle and no further judgment is required by the staff;
[0033] 7. Release the swing handle 31 and take the material out of the clamping channel, thus completing one processing step.
[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
