Device and method for processing edges of straight pipe water distributor

Abstract

The invention relates to a device for processing edges of a straight pipe water distributor, comprising a clamping component, a locating module and a hemispheroid pull block, wherein the clamping component comprises a left clamping block and a right clamping block which are symmetrically arranged; the locating module is a semicylinder matched with the inner wall of a pipe, the upper part of the locating module is provided with a locating and locking mechanism, and the locating and locking mechanism comprises a ball, a spring and a fastening screw which are symmetrically arranged and sequentially connected from inside to outside; and the hemispheroid pull block comprises a hemispheroid, a locating body capable of being fastened with the locating and locking mechanism is arranged at the lower side of the hemispheroid, and the upper part of the hemispheroid is connected with a pull rope fixing device. The device is simple in structure; by adopting the edge processing device and method, multiple outer edges of a water distributor can be simultaneously pulled out in one step; an outer edge guide hole is processed in advance, thus ensuring the quality of the outer edges; and the processed edges are consistent in shape, thus being beneficial to the subsequent welding of the water distributor, and improving the welding quality.

Description

technical field [0001] The invention belongs to the field of processing tooling for thin-walled straight tube arrangement water distributors, and in particular relates to a processing device and method for the edge of straight tube water distributors. Background technique [0002] At present, the common processing methods for the edge of the straight pipe arrangement type water separator are: 1. Drill holes on the straight pipe first, and then weld the water distribution pipe. 2. Punch holes on the straight pipe first, then pull out the flanging to form the outer edge, smooth the outer edge and then weld the water distribution pipe. 3. Reserve the edge forming channel on the fixed tooling of the straight pipe, pass high-pressure water from both ends of the straight pipe, and make the high pressure water rush out from the reserved edge forming channel to form the edge. [0003] Method 1 is simple to operate, but because two round pipes intersect to form an intersecting line,...

Problems solved by technology

[0003] Method 1 is simple to operate, but because two round pipes intersect to form an intersecting line, since the intersecting line is a space curve, it is difficult to weld, and the welding is not firm; Method 2 avoids the problem of intersecting line welding by forming an outer edge , since the straight pipe is directly punched, this will cause relatively large local deformation or even overall deformation to the main pipe, and secondly, because the formation of the outer edge is drawn through the inner edge flanging, the quality of the outer edge is not guaranteed; Method 3 flushes out the edge by water pressure, and the consistency of the shape of the edge is not guaranteed. For different numbers of edges, the requirements for water pressure and impact speed are different. This requires very high water pressure control, and it is difficult to good implementation
