Production process of wheel casing type parts

Abstract

The invention provides a production process of wheel casing type parts. The production process comprises the following steps: designing a forge piece and a pressing die; prefabricating a blank; forging and pressing the blank into the forge piece, specifically, the pressing die is subjected to preheating and heat preservation, the blank is heated, the heating temperature of the part, corresponding to a forged and pressed protruding part on the forge piece, of the blank is higher than the heating temperature of the rest of the blank, the heated blank is placed on the pressing die, and the blank is pressed into the forge piece; taking out the pressed forge piece, and removing flash of the forge piece; and after the forge piece is cooled, checking the forge piece, and repairing defects to obtain the wheel casing type parts. According to the production process, the wheel casing type parts are produced through a forging and extruding process method, the mechanical performance of the wheel casing type parts can be effectively improved, the machining period can be shortened, and the production cost is relatively low; and particularly, when the blank is heated before being pressed, the heating temperature of the part, corresponding to the forged and pressed protruding part on the forge piece, of the blank is higher so that different flowabilities can be obtained, and therefore the wheel casing type parts with high protruding parts can be machined more easily through forging.

Description

technical field [0001] The invention relates to the field of production of wheel cover parts for tobacco packaging machines, in particular to a production process for wheel cover parts. Background technique [0002] Wheel cover parts are usually used in tobacco packaging machines, and the structure of the wheel cover parts 100 is as follows: figure 1 As shown, it has an arc-shaped cover body 101 and a raised portion 102 protruding from the surface of the cover body 101, and wheel cover parts are usually made of copper alloy. At present, most of the above-mentioned copper alloy wheel cover parts 100 with higher protrusions 102 are produced by casting or welding processes, but these two production processes have the following problems: 1. Casting produces copper alloy wheel covers When casting such parts, quality defects are prone to occur, such as casting cracks, insufficient pouring, sand holes and pores, etc., resulting in poor performance of casting products, resulting in...

Problems solved by technology

At present, most of the above-mentioned copper alloy wheel cover parts 100 with higher protrusions 102 are produced by casting or welding processes, but these two production processes have the following problems: 1. Casting produces copper alloy wheel covers When casting such parts, quality defects are prone to occur, such as casting cracks, insufficient pouring, sand holes and pores, etc., resulting in poor performance of casting products, resulting in safety hazards in use of wheel cover parts processed by them, or short service life; 2. When welding and producing copper alloy wheel cover parts, it needs to be leveled, trimmed, qualitative and other procedures, the production cycle is long and the production cost is high
