A cotton thread braiding tube bending and shaping processing device

Abstract

This utility model relates to a cotton braided tube bending and shaping processing device, belonging to the field of cotton braided tube processing technology. It includes a support base, on which a hydraulic rod is fixedly connected. A clamping assembly is provided on the support base, and a bending block is provided on the top of the support base. A shaping assembly is provided on the bending block. The clamping assembly includes a connecting plate fixedly connected to the telescopic end of the hydraulic rod. A sliding member is slidably connected inside the connecting plate, and a threaded hole is provided on the sliding member. By setting up the clamping assembly, the pipe is positioned and clamped, thereby applying an axial pulling force to the pipe. This applies a reverse tensile force to the inner material of the pipe, offsetting some of the compressive stress and making the stress distribution on the inner and outer sides more uniform. Simultaneously, plastic tensile strain can be applied to the material, allowing some of the energy stored in the material during the elastic deformation stage to be released, thereby reducing the springback angle after bending.

Description

Technical Field

[0001] This utility model relates to the field of cotton braided tube processing technology, and to a cotton braided tube bending and shaping processing device. Background Technology

[0002] In modern industrial production and daily life, cotton braided tubing is widely used in many fields such as automotive braking systems, gas transmission, and sanitary facilities due to its good flexibility, certain pressure resistance, and cost-effectiveness.

[0003] However, cotton braided tubing faces many challenges during bending. Due to the inherent structural characteristics of cotton braided tubing, during conventional bending, the inner material is prone to wrinkling, denting, or even breakage due to concentrated compressive stress, which seriously affects the structural integrity and service life of the pipe. At the same time, although some existing equipment can achieve basic bending functions, it cannot effectively apply axial pulling force, making it difficult to balance the internal and external stresses during pipe bending, resulting in inconsistent product quality and thus affecting the yield of bent pipes.

[0004] To address the aforementioned issues, this application proposes a cotton thread braided tube bending and shaping processing device. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a cotton thread braiding tube bending and shaping processing device.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a cotton braided tube bending and shaping processing device, including a support base, a hydraulic rod fixedly connected to the support base, a clamping component provided on the support base, a bending block provided on the top of the support base, and a shaping component provided on the bending block;

[0007] The clamping assembly includes a connecting plate fixedly connected to the telescopic end of a hydraulic rod. A sliding member is slidably connected inside the connecting plate. The sliding member has a threaded hole, and a bolt is threadedly connected to the sliding member through the threaded hole. A fixing plate is rotatably connected to the bolt. A magnetic plate is fixedly connected to the fixing plate, and one side of the magnetic plate is in contact with the outer wall of the connecting plate. A clamping plate is fixedly connected to the sliding member. An electric telescopic rod is fixedly connected to the end of the clamping plate away from the sliding member. A downward pressure plate is rotatably connected to the telescopic end of the electric telescopic rod. A rotating plate is rotatably connected to the clamping plate.

[0008] The shaping component includes an airbag mounted on a bending block. A threaded pipe is fixedly connected to the outer wall of the airbag. A threaded ring is threadedly connected to the outer wall of the threaded pipe. A tee pipe is rotatably connected to the inner wall of the threaded ring. One end of the tee pipe is fitted with one end of the threaded pipe. By setting the shaping component, the bent pipe can be shaped.

[0009] The top of the support base has a limiting groove, and the bottom of the connecting plate is fixedly connected to a limiting rod. The outer wall of the limiting rod fits into the limiting groove of the support base. By setting the limiting groove and the limiting rod, the connecting plate is limited.

[0010] A positioning rod is fixedly connected to the top of the connecting plate, and the positioning rod is used to locate the bending position.

[0011] A measuring ruler is fixedly connected to the top of the connecting plate, with one side of the measuring ruler in contact with one side of the magnetic plate. By setting the measuring ruler, the position of the clamping plate can be adjusted.

[0012] A threaded rod is fixedly connected to the bottom of the bending block, and a nut is threadedly connected to the outer wall of the threaded rod. A fixing rod is fixedly connected to the bottom of the bending block, and the fixing rod is slidably connected to the support base. The bending block can be replaced by setting the threaded rod, nut and fixing rod.

[0013] The inner wall of the three-way pipe is fixedly connected with a guide, which guides the gas.

[0014] The beneficial effects of this utility model are:

[0015] By setting up clamping components, the pipe is positioned and clamped, thereby applying an axial pulling force to the pipe. This applies a reverse tensile force to the inner material of the pipe, offsetting some of the compressive stress and making the stress distribution on the inner and outer sides more uniform. At the same time, plastic tensile strain can be applied to the material, allowing some of the energy stored in the material during the elastic deformation stage to be released, thereby reducing the springback angle after bending.

[0016] By setting up shaping components, the pipe can be shaped after bending, thereby improving the bending quality and efficiency. At the same time, it avoids the dispersion of bending stress during bending, thus preventing problems such as wrinkles, cracks, and inner layer fractures caused by local compression.

[0038] Working principle:

[0039] This cotton braided tube bending and shaping processing device allows the pipe to be placed on a rotating plate 310 when bending is required. An electric telescopic rod 308 drives a lower pressure plate 309 downwards, clamping the pipe between the lower pressure plate 309 and the rotating plate 310. After clamping, a hydraulic rod 2 moves a connecting plate 301, which in turn moves a clamping plate 307 and the pipe. After moving a certain distance, the pipe is blocked by a bending block 4 and begins to bend. During bending, hot air is introduced into the airbag 501 through a tee pipe 504 and a threaded pipe 502 to facilitate bending. After bending, cold air is introduced into the airbag 501 through the tee pipe 504 and the threaded pipe 502 to shape the pipe.
