Cold and hot state casting rod peeler

Abstract

The invention discloses a cold and hot state casting rod peeler, relating to improvement of an aluminum section processing device. The peeler is characterized by comprising a stand, a rod inlet and clamp device, a sliding bed device, a rod pushing device, a peeling knife, a skin unloading device and a skin pushing device, wherein the rod inlet and clamp device comprises a left roller assembly, a lower roller assembly, a right roller assembly and an upper roller assembly; the peeling knife is arranged on the right side of a front memorial archway, the knife edge of the peeling knife is in a ring shape, and the centre line of the knife edge is arranged in a coaxial way together with a casting rod and a peeling oil cylinder; the peeling oil cylinder is horizontally installed on the right side of a rear memorial archway; and three skin unloading oil cylinders are evenly distributed and installed on the left side of the front memorial archway. The cold and hot state casting rod peeler has the beneficial effects that the peeling time is short, and the efficiency is high; secondary pollution is caused by peeling by cold cutting, while the hot peeling casting rod directly enters into an extruding machine; and compared with peeling by cutting, the hot peeling is less in burning loss.

Description

technical field [0001] The invention belongs to the technical field of non-ferrous metal processing and manufacturing, and relates to an improvement of aluminum profile processing equipment. Background technique [0002] Non-ferrous metal cast rods are used as the raw material of extrusion profile processing plants. When processing profiles, impurities on the surface of the cast rods must be removed, such as inclusions, pores, scale, etc., otherwise these defects will directly affect the quality of extruded profiles , with the increasing quality requirements of extruded profiles, peeling of cast rods is an indispensable process in the extruded profiles industry. Cast rod skins have been removed decades ago in large extrusion plants. [0003] The traditional peeling of cast rods is done by cutting and peeling with a lathe. Taking an aluminum alloy cast rod with a diameter of 520 mm and a length of 1500 mm as an example: 1) It takes 20 minutes to cool and peel each rod, and t...

[0003] The traditional peeling of cast rods is done by cutting and peeling with a lathe. Taking an aluminum alloy cast rod with a diameter of 520 mm and a length of 1500 mm as an example: 1) It takes 20 minutes to cool and peel each rod, and the processing time is long; 2) Cold cutting Peeling causes secondary pollution during cutting, warehousing, transport, and heating, which affects the quality of extruded profiles; 3) Cutting and peeling, there are still cutting grooves on the surface of the cast rod after peeling; 4) Cutting and peeling requires a factory building , lathes, personnel; 5) cutting and peeling, the skin is filamentous, and the surface area of ​​the peeled skin is several hundred times that of the thermally peeled skin. , due to the large surface area of ​​cold cutting dander, the burning loss rate is 15% during recycling and casting, which means that 1 ton of cutting dander must be oxidized into gas to volatilize 1 ton
