Abstract
The utility model discloses a rolling stainless steel inner casing hydraulic cylinder, which comprises a cylinder body 1, a stainless steel inner casing 2, the two ends of the cylinder body 1 are provided with convex rings on the inner walls, the stainless inner casing 2 is provided on the inner wall of the cylinder body 1, between the two ends of the inner casing 2 and the inner wall convex ring 4 an upper packing welding ring 3 is welded; during the dismounting and cleaning process, the inner casing of the utility model is free from the formation of burr or flash, and leakage, and the separation of the inner casing and the cylinder body, the utility model can be applied widely to the hydraulic cylinder of hydraulic prop in the mine exploration.
Description
The utility model relates to a kind of mining oil hydraulic cylinder, and specifically a kind of rolling in the dress stainless steel overlapped oil hydraulic cylinder.
Many in mining at present the oil hydraulic cylinder of this pillar is after using several years with outside injection type hydraulic pillar support works face top boards, and the inwall corrosion is serious, causes sealing bad, can not use and scraps.For addressing this problem, the technician once adopted measures such as oil hydraulic cylinder inner wall copper plating, nickel plating, plastic-blastings, all was eliminated because of poor effect.Adopted the method for in the oil hydraulic cylinder inwall rolls the dress stainless steel, overlapping in recent years, solved the anti-corrosion problem more effectively, but because interior sleeve wall thickness approaches (0,6 millimeter), and interior cover two ends are connected insecure with cylinder body, in dismounting, cleaning process, in stainless steel, overlap two ends easily and draw grain raising, overlap, even separate with hydraulic cylinder, so that oil hydraulic cylinder is scrapped.
The purpose of this utility model is to provide a kind of can make rolling that cover and hydraulic cylinder firmly are connected in the thin-wall stainless steel adorn the interior oil hydraulic cylinder that overlaps of stainless steel.
The utility model is achieved in that this rolls the interior cover of dress stainless steel oil hydraulic cylinder and is made of cover in cylinder body, the stainless steel, cylinder body two ends inwall is provided with bulge loop, cover rolls and is contained on the inboard wall of cylinder block in the stainless steel, the built-up welding ring is gone up in welding between interior cover two ends and the inboard wall of cylinder block bulge loop, the cover end is a smooth bevel with the bulge loop internal surface in the stainless steel, and cover in the stainless steel is fixed on the hydraulic cylinder.
The utility model has the advantages that: weld the built-up welding ring and make smooth bevel by cover two ends in stainless steel, make that cover firmly welds together with hydraulic cylinder in the stainless steel, overcome when dismounting, cleaning solution cylinder pressure, roll cover two ends grain raising in the dress stainless steel, overlap, leakage and in overlap the shortcoming of separating with hydraulic cylinder.
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the utility model cross-sectional schematic.
Make the utility model with reference to accompanying drawing 1.This rolls, and the cover oil hydraulic cylinder is made of cover 2 in cylinder body 1, the stainless steel in the dress stainless steel, its cylinder body 1 two ends inwall is provided with bulge loop 4, cover 2 rolls and is contained on cylinder body 1 inwall in the stainless steel, in the stainless steel between the two ends of cover 2 and the cylinder body 1 inwall bulge loop 4 welding go up built-up welding ring 3, realized overlapping in the stainless steel 2 and be connected with the firm of hydraulic cylinder 1.
Claims (2)
1, a kind of rolling in the dress stainless steel overlapped oil hydraulic cylinder, constitute by cover (2) in cylinder body (1), the stainless steel, it is characterized in that cylinder body (1) two ends inwall is provided with bulge loop (4), cover (2) rolls and is contained on cylinder body (1) inwall in the stainless steel, welds between the two ends of cover (2) and cylinder body (1) the inwall bulge loop (4) in the stainless steel and goes up built-up welding ring (3).
2, according to claim 1 rolling in the dress stainless steel overlapped oil hydraulic cylinder, and its feature overlaps (2) two ends in stainless steel and bulge loop (4) internal surface is a smooth bevel.
