A special-shaped pipe split structure connecting structure

Abstract

This utility model discloses a connecting structure for shaped tube splicing, including a plate body. The plate body is made of metal, and multiple bends are formed in a straight line along the width direction of the plate body, arranged sequentially along the length direction of the plate body. The plate body can be bent along the bends, and the two ends of the plate body can be connected to form a shaped tube. Using a flat metal plate instead of a shaped steel tube blank as raw material significantly reduces material costs. Stamping to form the bends and punching holes in the unfolded flat state avoids the "flatness and height" difficulties caused by the shaped tube structure, resulting in more precise blanking dimensions and more accurate hole processing. This effectively solves the technical problems of large dimensional errors and difficulty in removing burrs inside holes and on the end faces in traditional processes, thereby improving product dimensional stability and overall quality.

Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing and processing technology, specifically to a connection structure for assembling irregularly shaped tubes. Background Technology

[0002] Currently, the processing and forming technology of special-shaped tubes usually involves cutting short pieces of special-shaped steel tube blanks into shape, followed by stamping, chamfering, deburring, and punching. The processing is cumbersome. Due to the irregular shape of the special-shaped tubes, it is difficult to level them after cutting the short pieces. This inability to level them results in excessive errors in the cutting dimensions, which not only leads to low efficiency but also affects product quality.

[0003] Existing technical issues:

[0004] 1. High cost: The price of irregular tube blanks is high, and burrs inside the holes and on the end faces cannot be removed or cannot be completely removed;

[0005] 2. Unstable product dimensions: Large errors in cutting dimensions, and irregular tube structures that cannot be leveled. Utility Model Content

[0006] The purpose of this utility model is to solve the problems mentioned above in the background technology and to propose a connection structure for shaped tube splicing.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A non-circular tube splicing structure connection structure includes a plate body, the plate body being made of metal, and a bending portion forming in a straight line along the width direction of the plate body on the plate body surface. The number of bending portions is multiple, and the multiple bending portions are arranged sequentially along the length direction of the plate body.

[0009] The plate can be bent along the bending section, and the two ends of the plate can be connected to each other to form a special-shaped tube.

[0010] As a further aspect of this utility model, the plate body has multiple sets of holes.

[0011] As a further embodiment of this utility model: the hole is formed between the two bends.

[0012] As a further embodiment of this utility model: the number of holes in a set is two.

[0013] As a further embodiment of this utility model: the two ends of the plate are respectively formed with splicing interfaces that can be spliced ​​together.

[0014] As a further embodiment of this utility model: the splicing interfaces are a first splicing interface and a second splicing interface, and the first splicing interface can mesh with the second splicing interface.

[0015] As a further embodiment of this utility model, the two splicing interfaces are welded together for fixation.

[0016] As a further embodiment of this utility model, the two ends of the plate are welded together.

[0017] As a further embodiment of this utility model: the plate body unfolds into a planar object.

[0018] As a further embodiment of this utility model, the plate can be formed into a bent portion by stamping.

[0019] The beneficial effects of this utility model are:

[0020] Significantly reduces production costs and improves quality stability: Using flat metal sheets instead of shaped steel tube blanks as raw materials greatly reduces material costs. Stamping to form bends and punches in the unfolded flat state avoids the "flatness and height" difficulties caused by shaped tube structures, resulting in more precise blanking dimensions and more accurate hole machining. This effectively solves the technical problems of large dimensional errors and difficulty in removing burrs inside holes and on end faces in traditional processes, thereby improving product dimensional stability and overall quality.

[0021] Improving production efficiency and enhancing design flexibility: Flat plates can be efficiently processed with bending sections and holes through continuous stamping, and then quickly formed into irregularly shaped tubes through bending and end-to-end connections (such as toothed riveting and welding), significantly simplifying the process and improving production efficiency. Simultaneously, by adjusting the number and position of bending sections and the design of splicing joints, irregularly shaped tubes with various complex cross-sections such as rectangles, trapezoids, and polygons can be flexibly manufactured to meet diverse needs. The combination of riveting and welding further ensures the strength and reliability of the connection structure. Attached Figure Description
