Background technology
Monoblock type semitrailer axletree hot extrusion draw shaping hydraulic machine is the key equipment of shaping monoblock type semitrailer axletree, but domestic existing monoblock type semitrailer axletree hot extrusion draw shaping hydraulic machine technical merit is low at present, have many deficiencies when shaping monoblock type semitrailer axletree: it is low to adapt to the workpiece size ability, energy consumption is big, efficient is low, the extrusion molding precision is low, operation inconvenience etc.For this reason, the applicant improves at above technical deficiency.
Summary of the invention
For solving the technical deficiency of existing horizontal hydraulic machine, the purpose of this utility model provides a kind of adaptation workpiece size ability height, operate easy, energy consumption is low, the precision height carries out the integrally formed horizontal hydraulic machine of the hot extrusion draw to the tubulose axletree.
The utility model is solved by the following technical programs: monoblock type semitrailer axletree hot extrusion draw shaping hydraulic machine includes fuselage (1), side at fuselage (1) is provided with the horizontal master cylinder (2) that joins with hydraulic control device, the flat master slider of external end head water receiving (3) of the main oil cylinder piston bar (14) that matches with horizontal master cylinder (2), be that 45 ° of guide rails are connected and are fixed with axle head shaping dies bearing (4) between horizontal master slider (3) and the fuselage (1), opposite side at fuselage (1) is provided with bearing (8), be positioned on the fuselage (1) and be provided with and clamp the anchor clamps (7) that power set join between bearing (8) and the horizontal master slider (3), described hydraulic press opening is 3900-4200mm, described horizontal master slider stroke is 1400-1600mm, the depth of parallelism of horizontal master slider and work top is 0.03-0.04+ (0.1/1000), perpendicularity is 0.02-0.03+ (0.02/100), so the existing precision of hydraulic press ratio of precision improves.
Further measure is: the fast forward speed of described horizontal master slider is 152 ~ 430mm/s, increases 100mm/s than existing hydraulic press; Its extrusion speed is 40 ~ 83mm/s, increases 20mm/s than existing hydraulic press, and operating efficiency has improved 30%.The nominal pressure of described hydraulic press is 3500-5000KN, and than the low 1300-2800KN of 6300KN of existing hydraulic press, vertical clamping force is 500-800KN, than the low 1200-1500KN of 2000KN of existing hydraulic press.
Description of drawings
Fig. 1 is the utility model monoblock type semitrailer axletree hot extrusion draw shaping hydraulic machine structural front view;
Fig. 2 is the C-C cutaway view of Fig. 1;
Fig. 3 is the A-A vertical section schematic diagram of Fig. 1;
Fig. 4 is the B-B vertical section schematic diagram of Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4: fuselage 1 comprises that the section by the metallic plate welding is four longerons 15 of square tube shape, left part at four longerons 15 is welded with left side support 16, right part is welded with right support 17, form the fuselage 1 of frame structure, support the horizontal master cylinder 2 that has bolt connection and hydraulic control device to join on 16 on a left side, the external end head bolt of the main oil cylinder piston bar 14 that matches with horizontal master cylinder 2 is connected with horizontal master slider 3,45 ° of guide rails 10 that the Si Jiaochu of horizontal master slider 3 is processed with on the inboard of 45 ° of guide rails 18 and four longerons 15 match, and horizontal master slider 3 can be moved horizontally with respect to fuselage 1.Bolting has axle head shaping dies bearing 4 on the horizontal master slider 3, and bolting has bearing 8 in the support 17 of the right side of fuselage 1, is being provided with and is clamping the anchor clamps 7 that power set join on the longeron 15 above the fuselage 1 between bearing 8 and horizontal master slider 3.Wherein clamp the power set structure and be that bolting has fixed head 12 on two longerons 15 up, clamping cylinder 6 joins with fixed head 12, the external end head of the clamping piston bar 18 that matches with clamping cylinder 6 is connected grip slide 13, grip slide 13 is connected with the upper bolt of anchor clamps 7, and the lower bolt of anchor clamps 7 is fixed on two longerons 15 of below.
Wherein, the opening of hydraulic press is 3900-4200mm, than the opening increase 100-400mm of existing hydraulic press 3800mm; Horizontal master slider stroke is 1400-1600mm, increases 200-400mm than existing hydraulic press, and institute's processing work length is 2600-2800mm thus, increases more than the 200mm than existing hydraulic press, is suitable for the wider of making axletree, and it is more to make the axletree type; The depth of parallelism of horizontal master slider and work top is 0.03-0.04+ (0.1/1000), perpendicularity is 0.02-0.03+ (0.02/100), depth of parallelism 0.06+ (0.12/1000) than existing hydraulic press is lower with perpendicularity 0.04+ (0.025/100), has improved the extrusion molding precision of hydraulic press.And the fast forward speed of horizontal master slider is 152 ~ 430mm/s, increases 100mm/s than existing hydraulic press; The extrusion speed of horizontal master slider is 40 ~ 83mm/s, increases 20mm/s than existing hydraulic press, and operating efficiency improves 30%.The nominal pressure of hydraulic press is 3500-5000KN, and than the low 1300-2800KN of nominal pressure 6300KN of existing hydraulic press, required pressure reaches required extruding workpiece pressure just, and kinetic equation loss is little; Vertical clamping force is 500-800KN, hangs down 1200-1500KN than the 2000KN of existing hydraulic press, thereby energy savings more reduces cost.And this hydraulic press operating power is 150-168kw, than the low 70kw of existing hydraulic press, cuts down the consumption of energy greatly; Hydraulic press of the present utility model does not in addition have the dnockout cylinder, and is simpler, more convenient to operate than existing hydraulic press structure, simplifies production process, reduces the cost cost, is convenient to maintenance and operation.
Hydraulic press of the present utility model, during use with the heating of an end of workpiece 5 and be fixed on the anchor clamps 7, mould is contained on the horizontal master slider 3, be pressed in the shaping dies 11 by the end that is heated of pressure workpiece 5, make its shaping, axletree is structure as a whole, be whole axletree, need not any welding procedure, improved mechanical performance, not only solved in the prior art and concentrated a difficult problem that has hidden danger of quality because of the welding stress that axletree produced, especially adaptable workpiece size scope is wide, and the axletree type that increase can be made cuts down the consumption of energy greatly, improve the extrusion molding precision, operate simpler and easy.
