Embodiment 1

[0036] Such as image 3 As shown, the embodiment of the present invention provides the bearing cover of the core component of the engine, and one end surface of the designated bearing cover is the top surface 10, and the two sides of the top surface 10 are side surfaces 9, and the top surface 10 is provided with bolt holes 4 and positioning pin holes 3 , The bearing cover is provided with a semicircular hole 8, the top surface 10 is provided with a lock tile groove 5, the side surface 9 is provided with a thrust surface 6, and the thrust surface 6 is provided with a thrust groove 7.

[0037] Bearing cap technology of engine core parts, including casting technology and material removal processing technology, casting technology uses end cap 1 and mold body 2, such as figure 1 As shown, the end cover 1 and the mold main body 2 adopt a transition or clearance fit, and the mold main body 2 is made of metal material. After the mold main body 2 is cast, it expands when heated to achi...

Embodiment 2

[0052] Conduct a survey of step in the dematerialization process and existing processes:

[0053] The traditional process is:

[0054]

[0055] The daily production of traditional crafts is calculated on the basis of an operating rate of 85%, three-shift production, a daily output of 1,200 pieces, an investment of 8.42 million, and 21 workers.

[0056] The parts are 50 components, the customer processing fee is 10 yuan / piece, the labor cost is 260 yuan / day / person, and the manufacturing cost (knife, wind, water, electricity, liquid): 2 yuan / piece.

[0057] Annual gross profit = (1200 pieces / day * 10 yuan / piece - 260 yuan * 21 people - 2 yuan * 1200 pieces) * 350 days = 1.449 million.

[0058] The payback period of investment is 55 months.

[0059] The traditional process has defects such as a large proportion of labor costs, low processing efficiency, and a long payback period.

[0060] Process flow of the present invention is:

[0061]

[0062] The present invention...

Abstract

The invention provides a process for an engine core part bearing cover, and relates to the field of machining. The process for the engine core part bearing cover comprises a casting process and a material removing machining process, wherein an end cover and a mold body are used in the casting process, the end cover is matched with the mold body, the interior of the mold body is hollow, and the profile of the inner section of the mold body is consistent with the profile of a needed blank. According to the method, integral casting is adopted, blank slitting is carried out, compared with a traditional process that a single blank is cast through a sand mold, the production efficiency of the blank is improved; and meanwhile, compared with casting of the traditional process, the surface quality of the blank is better, clamping during material machining is better facilitated, the machining procedures can be reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a technology of a bearing cap of a core part of an engine. Background technique [0002] The bearing seat is a large and extra-large bearing seat that can withstand comprehensive loads and has a special structure. It has the characteristics of compact structure, sensitive rotation, and convenient maintenance of the device. The bearing seat is usually in two halves, and the two are covered with each other, and one half can be called the bearing cover. [0003] The production of the bearing cap is usually formed by casting, and then processed by machining to obtain the final product. [0004] Most of the traditional casting methods are sand casting. Sand casting refers to the casting method of producing castings in sand molds. The casting molds are easy to manufacture and can be adapted to single-piece production, batch production and mass production of castings. Fo...
