Embodiment Construction

[0047] Crankcase 1 of piston compressor Figure 1-5 The exemplary embodiment shown is provided with two body parts 2 , 3 and two end walls 4 , 5 . Cylinder support 6 is located inside the crankcase, the cylinder support in the Figure 4 and Figure 5 clearly visible in the Figure 14 more clearly visible. Due to the low number of components, the crankcase 1 can be manufactured in an economical and simple manner. Also, a durable and stiff construction is provided.

[0048] Now, based on Figure 6-14 , will further elucidate manufacturing as Figure 1-5 The crankcase approach is shown.

[0049] Image 6 An end wall blank 4' is shown. The end wall blank 4' can be obtained, for example, by laser cutting, water jet cutting or stamping of sheet steel material. Especially the first two manufacturing techniques have a high degree of accuracy, resulting in cut edges so fine that they do not require any finishing treatment. Using the same technique, the necessary recesses can...

Abstract

Method for manufacturing a crankcase of a piston compressor, wherein the piston compressor is provided with a crankcase which is provided with recesses for therein receiving cylinders and with at least an inlet opening, wherein from a flat sheet at least one substantially rectangular body blank is manufactured provided with the desired cylinder receiving recesses, wherein the body blank is then angle bent in an angle bending machine for forming a body part having a limited number of folds, wherein at least two substantially flat end walls are manufactured from a flat sheet, wherein thereupon the at least one body part and the at least two end walls are positioned with respect to each other using a positioning tool and are connected with each other with a welding robot for forming the crankcase. Also disclosed is a crankcase obtained with the method, and a piston compressor provided with such a crankcase.

Description

technical field [0001] The invention relates to a method of manufacturing a crankcase of a piston compressor provided with a crankcase provided with a recess for housing a cylinder therein and at least one inlet opening. Background technique [0002] From a practical point of view, it is known to cast the crankcase of a piston compressor and then to process the casting at the location where the bearing recesses, cylinder recesses, inlets and outlets are located, in order to use materials such as milling, boring, etc. Removal operations for final processing. Such a piston compressor is marketed by the applicant, for example under the series name Grasso 6. Such piston compressors are relatively inexpensive to manufacture. However, due to the relatively thick walls of the crankcase, such piston compressors with cast crankcases require active cooling by means of a cooling medium. However, having such a cooling medium arrangement with a piston compressor increases the cost of ...
