Abstract
The utility model discloses a hydraulic cylinder used wrist pin welding component. The hydraulic cylinder used wrist pin welding component comprises a stainless sexangular head and a manganese steel cylinder, which are independently machined and formed, and the hydraulic cylinder used wrist pin welding component is characterized in that the manganese steel cylinder is connected onto the stainless sexangular head by welding, a galvanized hard chromium layer is arranged on the surface of the manganese steel cylinder, the manganese steel cylinder is connected onto the stainless sexangular head by welding by adopting a 316 stainless welding material, and the stainless sexangular head can adopts the 316 stainless welding material. The hydraulic cylinder used wrist pin welding component provided by the utility model has the advantages that the processing is simple, the stainless sexangular head can be directly cut and machined through a section, the milling processing technique is avoided, the production efficiency is improved to a great extent, the raw material cost is reduced at the same time, and higher machining precision, namely higher roundness and roughness are guaranteed, and the wrist pin welding component is suitable for mass production in a factory.
Description
Technical field
The utility model belongs to the wrist pin technical field, especially relates to a kind of oil hydraulic cylinder wrist pin weld assembly.
Background technique
Existing oil hydraulic cylinder wrist pin weld assembly, its hexagon head and cylindrical body all adopt the machine shaping of stainless steel material one, cause thus that difficulty of processing is big, cost of production is high, and the circularity of wrist pin and roughness all are difficult to control, can not reach some device requirement.
The model utility content
The purpose of this utility model is to provide in order to solve above-mentioned the deficiencies in the prior art that a kind of processing is simple, manufacturing efficiency is high, cost is low, and has than the oil hydraulic cylinder of high manufacturing accuracy wrist pin weld assembly.
To achieve these goals, the designed oil hydraulic cylinder of the utility model wrist pin weld assembly comprises the stainless steel hexagon head and the manganese steel cylindrical body that independently shape, it is characterized in that on the stainless steel hexagon head by being welded to connect the manganese steel cylindrical body.Be provided with the durionise layer at the manganese steel periphery.Described is to be welded to connect with 316 stainless steel welding materials by being welded to connect the manganese steel cylindrical body on the stainless steel hexagon head.At this, described stainless steel hexagon head adopts 316 stainless steel materials.
The oil hydraulic cylinder that the utility model obtains is simple with the processing of wrist pin weld assembly, the stainless steel hexagon head can directly be used the section bar cutting process, avoided Milling Process technology, suitable factory mass manufacturing operation, improved manufacturing efficiency to a great extent, reduced the cost of raw material simultaneously, and can guarantee to have, promptly had higher circularity and roughness than high manufacturing accuracy.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model;
Fig. 2 is a manganese steel round column structure schematic representation of the present utility model;
Fig. 3 is 316 stainless steel hexagon head structural representations of the present utility model.
Among the figure: stainless steel hexagon head 1, manganese steel cylinder 2.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment:
As shown in Figure 1 to Figure 3, a kind of oil hydraulic cylinder wrist pin weld assembly that present embodiment provides comprises the stainless steel hexagon head 1 and the manganese steel cylindrical body 2 that independently shape, on stainless steel hexagon head 1 by being welded to connect manganese steel cylindrical body 2; Be provided with the durionise layer on manganese steel cylinder 2 surfaces; Present embodiment is described to be to be welded to connect with 316 stainless steel welding materials by being welded to connect manganese steel cylindrical body 2 on stainless steel hexagon head 1.
The stainless steel hexagon head 1 of present embodiment adopts 316 stainless steel materials, has strong anti-corrosive properties; Cylinder is a manganese steel material cylindrical body, and its electroplating surface hard chrome has higher wear resistance and low processing cost.Stainless steel hexagon head 1 and manganese steel cylinder 2 pass through 316 stainless steel welding sticks at CO
2Be welded as a whole weld strength 〉=800N.m under the protection gas.When stainless steel hexagon head 1 and manganese steel cylindrical body 2 two-part are independently shaped, manganese steel cylindrical body 2 can carry out outer surface fine finishing by high accuracy centerless grinding machine, make its external diameter tolerance can control to the um level, and have higher circularity and roughness, its surface roughness can reach below the Ra0.08; 316 stainless steel hexagon heads 1 can directly be used the section bar cutting process, have avoided Milling Process technology, and suitable factory mass manufacturing operation has improved manufacturing efficiency to a great extent, has reduced the cost of raw material simultaneously.
