Embodiment

[0028] Such as figure 1 and figure 2 As shown, the bimetal barrel processing technology provided in this embodiment includes the following steps:

[0029] (1) Milling and grinding machine barrel jacket 1: Rough milling is carried out on the six sides of machine barrel jacket 1 by horizontal milling. After rough milling, the machining allowance of barrel jacket 1 is ≤0.1mm. After milling, use flat grinding The method is to grind the six sides of the barrel jacket 1, and the parallelism of the barrel jacket 1 after grinding is 0.02mm;

[0030] (2) Waterway processing: Drill and tap the waterway hole 2, water inlet hole and water outlet hole on the machine barrel jacket 1, and weld the sealing plate 3 around the machine barrel jacket 1 to process the waterway, and perform the first waterway leakage after the waterway processing is completed Inspection, can check whether there is water leakage in the water channel in the early stage, and can repair it in time, and then perform ...

Abstract

The invention discloses a double-metal machine barrel machining process. The double-metal machine barrel machining process comprises the following steps: (1) milling and grinding an outer sleeve of amachine barrel; (2) drilling a tapping water channel hole, a water charging hole and a water discharging hole in the outer sleeve of the machine barrel, welding sealing plates and machining water channels at the four sides of the outer sleeve of the machine barrel, and performing a leakage test after the water channels are machined; (3) machining a waist round hole in the center of the outer sleeve of the machine barrel, and pressing a steel sleeve into the waist round hole by means of hot charging; (4) machining an 8-shaped hole in the steel sleeve; and (5) performing finish-milling on the four sides by adopting a fly-cutter, performing finish-milling on a shoulder surface by adopting an alloy end mill, polishing the two end faces of the outer sleeve of the machine barrel by means of plane abrasion, and drilling each screw hole, each thread hole, each locking hole, each probe hole and each pin hole. The double-metal machine barrel machining process disclosed by the invention is simplein a machining process; a machined product is relatively high in wear resistance and corrosion resistance; the service life of a double-metal machine barrel is prolonged; and the production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a bimetallic barrel processing technology. Background technique [0002] With the rapid development of the chemical industry, various new plastic raw materials are constantly emerging, and high-strength reinforced plastic raw materials often contain reinforcing fibers such as carbon, asbestos, glass, and boron. In order to obtain the special properties of raw materials or reduce the cost of raw materials, a certain proportion of fillers, such as chalk, silica, barite, mica, etc., will be added to the plastic resin. Because the addition of these reinforcing agents and fillers aggravates the wear and corrosion of the barrel and screw, the processing and production efficiency of the extruder is reduced, the quality of the finished product is unstable, and the cost of repair and maintenance increases, which affects the overall machine. economic benefits. ...
