Description

Technical Field

[0001] The utility model relates to the field of pipe bending, in particular to a pipe bending device for tables and chairs. Background Art

[0002] Tables and chairs can be seen everywhere in our lives and are used every day, but we feel that they are inconspicuous and do not provide much help in the process of use. However, once we leave them, we cannot work and live comfortably. The existing production of tables and chairs has begun to use mechanical equipment to replace manual production. In the process of pipe bending, mechanical bending equipment is generally used, including automatic bending machines and manual bending machines. Most automatic bending machines are CNC bending machines, which are large in size and inconvenient to move.

[0003] In a Chinese patent, a table and chair pipe bending device is disclosed, and its patent number is CN210231103U. In the table and chair pipe bending device of the patent, it includes a base, an L-shaped rod is fixedly welded on the other side of the first sliding sleeve, a groove is opened on the upper part of the end of the L-shaped rod away from the column, a cross bar is fixedly welded on the upper end of the column, the first pulley is movably sleeved on the outside of the cross bar, the side of the cross bar away from the column is movably sleeved with a first concave wheel, a second sliding sleeve is slidably sleeved on the rotating rod, a second concave wheel is installed on one side of the second sliding sleeve through a rotating shaft, and a second adjustment knob is threadedly installed on the side of the second sliding sleeve away from the second concave wheel, a motor is fixedly installed on the base by bolts, a second pulley is keyed on the output shaft of the motor, and the second pulley is connected to the first pulley through a belt drive. A table and chair pipe bending device can bend pipes of different outer diameters and can adjust the length of the bending position of the pipe.

[0004] The above-mentioned published patents have the following disadvantages:

[0005] (1) In reality, different tables and chairs have different requirements for the bent pipes they support, and the angles at which the bent pipes need to be bent are also different. In the bending process, the bending device in the prior art cannot accurately determine the bending position and curvature of the bent pipe because the sizes and motion trajectories of the components used for bending are roughly the same, which affects the normal use of the bent pipe.

[0006] (2) In the prior art, when using a bending device for bending, there is no limiting structure at the position where the bending device places the pipe, which causes the position of the pipe to shift during the extrusion and bending process, and also causes the pipe to be squeezed and fall off the surface of the device during bending, affecting the bending effect.

[0007] (3) In the prior art, during the bending process of the pipe, since a device is required to squeeze it, the surface of the pipe will be subjected to external squeezing force, causing damage to the surface of the pipe, affecting the subsequent normal use of the pipe. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 5 As shown, a table and chair pipe bending device includes a table top 1, wherein the bottom surface of the table top 1 is fixed with support legs 2 to support the table top 1, a fixing component 3 located on one side of the surface of the table top 1 is provided with a support member 301, and a spring 302 between the two support members 301 enables a protective pad 303 to fit the pipe for fixing, a protective pad 404 on the surface of the bending member 4 located on one side of the fixing component 3 is provided to protect the pipe, and a buckle component 5 is provided on the inner side of the support block 403 on the bottom surface of the bending member 4, and the buckle component 5 is provided with a linkage member 503 to cooperate with the fixed block 401 fixed on the bottom surface of the bending member 4 to fix the bending member 4, a driving component 6 located on the bottom surface of the table top 1 is provided with a stepping motor 601 to drive a slider 603 to slide on the inner side of an arc groove 604 on the surface of the table top 1 through a driving component 602, and a fixing component 7 located on the upper surface of the slider 603 is provided with a support member 701 to fix the other end of the pipe through a spring 4 702.

[0029] A limiting rod 402 fixed on the surface of the table top 1 is arranged inside the bending member 4 and is connected to a supporting block 403 .

[0030] Through the above technical solution, the position of the bending member 4 is limited by setting the limiting rod 402, so as to prevent the bending member 4 from sliding during the bending process and affecting the bending effect of the pipe.

[0031] The buckle assembly 5 is provided with a groove 501 slidably connected to the push piece 502, so that the push piece 502 can control the linkage piece 503 on the bottom surface to buckle and fix. A spring 2 504 is provided on the bottom surface of the linkage piece 503 to assist it to rotate through the inner fixing rod 505.

[0032] Through the above technical solution, under the drive of the push member 502, the linkage member 503 can be clamped on the inner side of the fixing block 401 under the elastic drive of the second spring 504, so as to facilitate the disassembly, assembly and replacement of the bending member 4.

[0033] The slider 603 slidably connected to the inner side of the arc groove 604 rotates inside the driving member 602 through the rotating member 605 at the bottom end.

[0034] Through the above technical solution, under the action of the rotating member 605, the slider 603 of the fixing component 2 7 can be rotated during the process of fixing the pipe to bend, ensuring that the pipe body will not be pulled too much and damaged.

[0035] A fixed shaft 703 is disposed inside the second support member 701 to connect to a rolling roller 704 .

[0036] Through the above technical solution, when the roller 704 rolls, it is ensured that the tube fixed by the roller 704 will not be excessively pulled during the bending process, thereby avoiding damage to the tube.

[0037] An auxiliary block 506 is disposed on the bottom surface of the fixed block 401 , and a spring 507 fixed to the inner side of the groove 501 is disposed on the bottom surface of the auxiliary block 506 .

[0038] Through the above technical solution, with the help of the elastic force of the spring three 507, the auxiliary block 506 can support the fixed block 401, so that the fixed block 401 can be smoothly detached from the inner side of the groove 501, which is convenient for disconnection.

[0039] During use, when the user uses the table and chair pipe bending device, the stepper motor 601 is driven to stop the fixing component 2 7 in the middle position of the arc groove 604, so that the fixing component 1 3 is parallel to the fixing component 2 7, and the pipe to be bent is passed through the inner side of the support member 1 301 and the support member 2 701. Under the elastic force of the spring 1 302 and the spring 4 702, the two support members can fit the fixed pipe, and the pressing member 502 is pressed to allow the linkage member 503 to rotate around the fixing rod 505, so that the fixing block 401 can be separated from the linkage member 503, and a suitable bending member 4 is replaced through it, and the stepper motor 601 is started, and its forward or reverse rotation is adjusted according to the bending requirements, so that the fixing component 2 7 slides on the inner side of the arc groove 604 through the slider 603, and the arc structure of the bending member 4 is used to bend the pipe.
