[0002] The wear-resistant collar is one of the important accessories that are directly formed on the piston when forming the piston to install the piston ring. At present, the manufacturing process of the wear-resistant collar is all to manufacture the cylinder first, and then cut the cylinder into several pieces with a machine tool. A collar ring, and then use the CNC machine tool to process the collar ring into a wear-resistant collar. The shortcoming is that it is a waste of time and material after cutting by the machine tool.

Embodiment Construction
[0022] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see figure 1 — Figure 4 : the manufacture method of single wear-resistant collar, completes as follows:
[0023] (1) Stick the single mold of the wear-resistant collar to the mold plate of the molding machine; make the sand boxes that need to be casted and stack them into 10 stacks, which saves space and facilitates rapid casting;
[0024] (2) According to the parts by weight of the following chemical components of the wear-resistant collar: C: 2.4-2.8 parts, Si: 1.8-2.4 parts, Mn1.0-1.4 parts, Ni: 13.5-17 parts, Cu: 5.0- 7.0 copies, S: 0-1 copies, P: 0-0.1 copies;
[0025] (3) Use a frequency conversion induction furnace to smelt ingredients into molten iron, and control the temperature of the molten iron to be 1450-1580°C; add 0.5-0.7% of the molten iron inoculant to the ladle for treatment, and cast it into the sand box made. Demolding after n...

The invention belongs to the technical field of piston fittings and relates to a wearable monomeric collar and a manufacturing method thereof. The wearable monomeric collar is composed of 2.4 to 2.8 weight parts of C, 1.8 to 2.4 weight parts of Si, 1.0 to 1.4 weight parts of Mn, 13.5 to 17 weight parts of Ni, 5.0 to 7.0 weight parts of Cu, 0 to 1 weight part of S, 0 to 0.1 parts of P and 0.08 to 0.18 weight parts of nucleating agent. The manufacturing method for the wearable monomeric collar includes: (1) bonding a monomeric mold of the wearable collar on a template of a molding machine; (2) preparing materials according to the weight parts of the chemical ingredients of the wearable collar; (3) smelting the materials into molten iron through a variable-frequency induction furnace, casting into a sand box, and de-molding after naturally cooling; (4) machining on a numerically-controlled machine tool to obtain the annular wearable collar. The wearable monomeric collar and the manufacturing method thereof have advantages that the semi-finished wearable monomeric collar can be directly processed into finished product by means of the manufacturing method, the processing is finished easily and quickly, the raw materials are saved, and the manufacturing method is suitable for manufacturing the wearable monomeric collar.
Description
technical field [0001] The invention belongs to the technical field of piston accessories, in particular to a method for manufacturing a single wear-resistant collar for forming a piston. Background technique [0002] The wear-resistant collar is one of the important accessories that are directly formed on the piston when forming the piston to install the piston ring. At present, the manufacturing process of the wear-resistant collar is all to manufacture the cylinder first, and then cut the cylinder into several pieces with a machine tool. A collar ring, and then use a CNC machine tool to process the collar ring into a wear-resistant collar. The shortcoming is that it is a waste of time and material after cutting by the machine tool. Contents of the invention [0003] The object of the present invention is to provide a simple, fast and raw material-saving single wear-resistant collar and its manufacturing method. [0004] The purpose of the present invention is achieved ...
