Embodiment

[0028] As shown in accompanying drawing, a kind of preparation method of tin bronze tube specifically comprises the following steps:

[0029] (1) Select electrolytic copper as the raw material for production, and use a power frequency induction furnace to melt the raw material. As a preferred solution, the electrolytic copper uses 1# electrolytic copper, and the power frequency induction furnace used is a high-power power frequency induction furnace that can be used in a short time Melt the raw material.

[0030] (2) Use the fully continuous horizontal dummy mechanism to cast copper water into copper ingots; using the fully continuous horizontal dummy mechanism can quickly and stably cast copper water into copper ingots;

[0031] (3) The copper ingots are shelled and extruded into various rough tubes by using a hydraulic double-action extrusion machine; the advanced hydraulic double-action extrusion machine can effectively and quickly shell the copper ingots and extrude them i...

Abstract

The invention discloses a method for manufacturing a bronze pipe, specifically comprising the following steps: selecting and melting raw materials; casting copper water into copper ingots; decladding the copper ingots and squeezing the copper ingots into various blank pipes; reducing one end of the blank pipe, removing oxide skins of the surface of the blank pipe; annealing the copper pipe to be softened; stretching the pipe materials to reach the requirement of customers through a frequency conversion stretcher; correcting the stretched copper pipe to the best straightness by a straightener; sawing the copper pipe into various lengths by a saw bit; removing burrs at two ends of the copper pipe; and testing to obtain finished goods. The method of manufacturing the bronze pipe provided by the invention has strong maneuverability, high efficiency, rational process design and high quality of the obtained bronze pipe.

Description

technical field [0001] The invention relates to a method for preparing a copper tube, in particular to a method for preparing a tin bronze tube. Background technique [0002] In the field of machinery, the demand for various types of parts is increasing, such as bearing bushes, connecting rods, bushings, gears, etc. Among the general suppliers of copper tube raw materials, they provide specific solid copper tubes according to customer requirements materials, but parts such as bushings and gears must first process solid copper tube materials into hollow copper tube bodies, and then further process them into various accessories. In the existing technology, in the process of processing the raw materials of solid copper pipes into hollow copper pipe body materials, due to immature technology and defects in equipment precision, the quality cannot meet the requirements, which not only fails to meet the needs of customers, but also greatly reduces the Enterprise productivity. Co...
