Description

Technical Field

[0001] This utility model relates to the field of stainless steel bar technology, and in particular to a high-precision stainless steel bar. Background Technology

[0002] Existing high-precision stainless steel bars are assembled by using a fixing device to combine two or more stainless steel bars into lengths that can be freely combined according to usage requirements. A fixing core is then inserted through the entire assembly of stainless steel bars, which improves the assembly efficiency between stainless steel bars. However, the method of using a long fixing core to assemble the bars places high demands on the fixing core and is difficult to install, making operation inconvenient and affecting assembly efficiency. Furthermore, it is not easy to disassemble the bars and fixing core during recycling, resulting in recycling difficulties and limiting its use. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a high-precision stainless steel bar. By setting conical blocks and clamping blocks at both ends of the bar body, the processing device can easily fix the bar body through the clamping blocks, and the tip and other components can be inserted into the positioning hole to improve the processing effect. At the same time, a detachable bar core can be installed inside the bar body, which reduces the weight of the bar and increases its strength. The bar core can be removed when recycling the bar body, and the bar body and the bar core can be recycled separately, reducing the difficulty of recycling. By installing two different connecting blocks at both ends of the bar core, two bar bodies can be connected together through the connecting blocks, and the bar bodies can be freely combined according to the required length, improving the assembly efficiency between bars.

[0014] Compared with existing technologies, by setting conical blocks and clamping blocks at both ends of the bar body, the processing device can easily fix the bar body through the clamping blocks, and the tip and other components can be inserted into the positioning hole, improving the processing effect. At the same time, a detachable bar core can be installed inside the bar body, reducing the weight of the bar and increasing its strength. The bar core can also be removed when recycling the bar body, allowing for separate recycling of the bar body and the bar core, reducing the difficulty of recycling. Furthermore, by installing two different connecting blocks at both ends of the bar core, two bar bodies can be connected together through the connecting blocks, allowing the bar bodies to be freely combined according to the required length, improving the assembly efficiency between bars.
