角铁弯圆弧是冷作中比较麻烦的工作,一般都需要有专用设备来加工,若采用手工加工,则很费力,且质量不好,特别是内弯时更困难。现介绍一种简易的角铁弯圆弧方法,质量好,简单方便,适于单件小批量生产。一、角铁外弯(见图1) 先将两根角铁背向用“C”字夹头夹紧。在两角铁的外合缝处(即角铁外圆弧边)每隔H≈1/2r距离,用电焊焊牢;内合缝处(即角铁内圆弧根部)可以焊上几点,也可以不焊。这样就可以直接在靠模上弯圆,弯圆后再将焊点铲除,即成为所需要的圆弧角铁。二、角铁内弯(见图2)
Corner arc bending arc is more troublesome work in cold work, generally require special equipment to process, if the use of manual processing, it is laborious, and the quality is not good, especially more difficult when the bend. Now introduce a simple method of angle iron curved arc, good quality, simple and convenient, suitable for small single-piece production. First, the angle iron cornering (see Figure 1) First two angle iron back with “C” chuck chuck. In the outer corner of the two iron joints (that is, the angle of the outer edge of the arc) every H ≈ 1 / 2r distance, with electric welding jail; within the seam (ie angle iron root arc) can be welded on a few points , You can not weld. So that you can bend directly on the mold round, after the rounding of welding points eradication, that is, become the required arc angle iron. Second, the angle iron bend (see Figure 2)
