Embodiment 1

[0031]The present invention is a surface texturing method for improving the wear resistance of the guide rail of a sand core molding machine. The two-layer groove-type texture structure is processed by micro-milling, and the texture appearance is as follows: figure 2 , image 3 As shown, the texture parameters are as follows: the groove depth h of the first layer of groove 1 1 =0.02mm, total groove depth h 2 =0.42mm; first layer groove width w 1 =1.50mm; the groove width w of the second layer of groove 2 2 = 1.00mm; groove spacing s = 3.05mm, the surface of the guide rail 3 to be processed is firstly finished, so that the surface roughness Ra of the guide rail is about 0.10 μm, after the surface of the guide rail 3 is finished, the diameter is passed through the high-speed micro-milling machine The micro milling cutter is used to process the groove texture. First, the first layer of groove 1 is processed. After the tool setting is completed, the milling cutter rotates at ...

Embodiment 2

[0033] The two-layer pit-type texture structure is processed by micro-milling, and the texture appearance is as follows Figure 4 , Figure 5 shown. The texture parameters are as follows: the pit depth h of the pit 4 of the first layer 3 =0.02mm, the total depth of pits h 4 =0.42mm; the first layer pit diameter d 1 =Φ1.50mm, the diameter d of the pit 5 on the second layer 2 =Φ1.00mm; X-direction and Y-direction spacing s 1 =s 2 = 3.05 mm. First, the surface of the guide rail 3 to be processed is finished, so that the surface roughness Ra of the guide rail is about 0.10 μm. Machining the pit 4 of the first layer: After the tool setting, the milling cutter with a diameter of Φ1mm rotates at a high speed of 40000r / min at a high speed of 0.50mm / s and descends 0.12mm relative to the surface of the guide rail along the Z negative direction at a feed speed of 0.50mm / s, and then mills The knife takes the current tool axis as the center of rotation, and mills the first la...

Abstract

The invention discloses a surface texturing method for improving wear resistance of guiding rails of a sand core moulding machine. Regularity of distribution of the sizes of sands are determined by conducting a statistical analysis to the size range of sands, a two-layer texturing structure is designed according to the size range of sands: the first layer texturing structure is used for generatinga hydrodynamic effect, a hydrodynamic oil film is formed, separation of surfaces of upper and lower guiding rails is facilitated; the second texturing structure is used for storing lubricating oils and capturing sands, when the depth of the second texturing structure is larger, more lubricating oils can be stored, which is used for supplying lubricating oils needed by the guiding rail surfaces, meanwhile, capturing more sands and reducing abrasive wear are facilitated, the two-layer texturing structure comprises two types of structures which are a two-layer groove type texturing structure anda two-layer concave type texturing structure. According to the surface texturing method for improving wear resistance of the guiding rails of the sand core moulding machine, the problem of poor guiding rails wear resistance of the sand core moulding machine in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of surface texture for wear resistance of sand core molding machine guide rails, and in particular relates to a surface texturing method for improving the wear resistance of sand core molding machine guide rails. Background technique [0002] The sand core molding machine is the core equipment in the foundry industry. The sand core molding machine fills the loose molding sand into the sand box; through vibration, compaction, vibration pressure, injection pressure and other methods, the loose molding sand is compacted to obtain high strength. The sand mold, and finally the formed sand core is taken out of the mold. There are a lot of sand in the working environment of the sand core molding machine. When the sand is embedded in the surface of the guide rail of the sand core molding machine, severe abrasive wear will occur on the surface of the upper and lower guide rails. At the same time, the sand will break ...
