Abstract
The utility model discloses a crankshaft of an ingot tipping device. The crankshaft comprises a crank I, a crank II and a shaft, wherein, the crank I and the crank II are respectively connected with the shaft through keys; the crank I, the crank II and the shaft are all made of 42CrMo steel; the crank I and the crank II are both in interference fit and assembled with the shaft; and the keys are flat keys. Compared with the crankshaft in the prior art, the crankshaft disclosed by the utility model has the remarkable advantages that a split structure is adopted, parts are connected by using the flat keys, so that the forging cost, the heat treatment cost and the machining cost are reduced while the coaxiality of shaft necks of the crank I and the crank II at the two ends of the crankshaft is guaranteed, the defect of poor steel welding performance of the crankshaft is corrected, the designing requirement and the processing requirement for a middle shaft neck and the assembly requirement for the shaft necks at the two ends of the crankshaft are met, the economic benefit is great, and the great social benefit can be created.
Description
Technical field
The utility model relates to and turns over ingot device, is specifically related to a kind of bent axle that turns over ingot device.
Background technique
Turning over ingot device mainly is made up of motor, speed reducer, bent axle, connecting rod assembling and tipping bucket body; The steel ingot of heavily about 60t that it mainly is used for clamp in the soaking pit is hung out vertically is put on the tipping bucket; Be turned to again and receive on the ingot roller-way and be transported to be rolled processing in the milling train; Bent axle is the important component part in the actuator, and the centre distance of bent axle is the important parameter that the switching mechanism phase place guarantees, must reach requirement on machining accuracy and could satisfy use; Its intermediate journal and connecting rod assembling, two ends axle journal and bearing support and coupling assembling.
Existing bent axle is the solid forging of 45 steel; Weight reaches 2.5t approximately, the about 1800mm * 1190mm of boundary dimension * 520mm, and the defective of this structure is: solid forging moulding expense is higher; The outer garden of intermediate journal processing difficulties; Whole processing cost is high, and 45 steel body quenching and tempering hardnesses and intensity are all lower, not wear-resisting.
Summary of the invention
Goal of the invention: to the deficiency that exists in the existing technology, the purpose of the utility model provides a kind of bent axle that turns over ingot device, reduces manufacture cost when can satisfy usage requirement to be implemented in, and prolongs its working life.
Technological scheme: in order to realize the foregoing invention purpose, the technological scheme that the present invention adopts is following: a kind of bent axle that turns over ingot device, comprise crank one, crank two and axle, and described crank one is connected with axle through key respectively with crank two.
Said crank one, crank two and axle are processed by the 42CrMo steel.
Said crank one, crank two are interference fit with the assembling that cooperates between the axle.
Described key is a flat key.
The bent axle of the utility model is to the relatively poor defective of bent axle steel weldability in the existing technology, checks through designing and calculating; According to intensity and wear resistance requirement, bent axle is reelected and is used Alloy Constructional Steel, and material is the 42CrMo steel; Consider that this kind material weldability is poor,, adopt flat key to connect for avoiding welding; Bent axle is divided into parts such as crank one, crank two and axle and forges separately, interference fit prevents that effectively the coaxality of crankshaft two end axle journal is overproof.
Beneficial effect: compare with bent axle of the prior art; The remarkable advantage of the utility model bent axle is: adopt and divide body structure; And, in the requirement of the coaxality that guarantees crankshaft two end crank one, two axle journals, make forging, heat treatment, machining cost reduce with the connection of flat key realization each several part; Overcome the relatively poor defective of bent axle steel weldability; And realized the matching requirements of design, processing and the two ends axle journal of intermediate journal having good economic benefits, can produce good social benefit.
Description of drawings
Fig. 1 is the structural representation that turns over the bent axle of ingot device;
Fig. 2 is that the c-c of Fig. 1 is to view.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As depicted in figs. 1 and 2, the bent axle that turns over ingot device comprises crank 1, crank 22 and axle 3, and crank 1 is connected with axle 3 through key 4 respectively with crank 22.Crank 1, crank 22 and axle 3 are processed by the 42CrMo steel.Crank 1, crank 22 are interference fit with the assembling that cooperates between the axle 3.Key 4 is a flat key.
The bent axle of the utility model is checked through designing and calculating, according to intensity and wear resistance requirement; Bent axle is reelected and is used Alloy Constructional Steel, and material is the 42CrMo steel, considers that this kind material weldability is poor; For avoiding welding, adopt flat key to connect, bent axle is divided into parts such as crank one, crank two and axle and forges separately; Interference fit prevents that effectively the coaxality of crankshaft two end axle journal is overproof.
Because the interference fit difficulty, warp calculates, and considers machining error, and guarantees to leave certain interval, need be heated to about 200 ℃ of hot pressing attire requirements of accomplishing crank one, crank two and intermediate journal.Intermediate journal cylindrical, keyway with bent axle; Endoporus, keyway that crank one, crank two cooperate with bent axle are machined to size requirement after quenching with Subsequent tempering; Crank one, crank two remaining part cylindricals and end face all leave the 10mm surplus; Assemble for about 200 ℃ in heating-up temperature, assembling back reprocessing crank one, crank two remaining part cylindricals and end face be to requiring, the coaxality that guarantees the crankshaft two end axle journal require and with the required distance of intermediate journal.
Because the coaxality of crankshaft two end axle journal requires to be φ 0.025; And require to ± 0.02 with the centre distance of jack shaft, so it is long in course of working, 10mm technology to be reserved at the intermediate journal two ends, as displacement datum; Utilize the cylindrical centering; Make the crankshaft two end center hole respectively through boring machine digital display coordinate, and require crankshaft journal is radially located to revolve knife bar and process a segment length 50mm basic circle with flat, guarantee the coaxality and and the required distance of jack shaft of two bent axle cylindricals after the cooperation processing.In the external coordination course of working, require use the floral disc counterweight, the headstock spindle hole is settled and is toply formed Double Tops with tailstock centre, the standard mandrel detects coaxial back size, through the 50mm basic circle check, the trial cut processing excircles, guarantee to process after errorless.
Compare with bent axle of the prior art, the remarkable advantage of the utility model bent axle is: adopt and divide body structure, and realize that with flat key each several part connects; In the requirement of the coaxality that guarantees crankshaft two end crank one, two axle journals; Make forging, heat treatment, machining cost reduce, overcome the relatively poor defective of bent axle steel weldability, and realized the matching requirements of design, processing and the two ends axle journal of intermediate journal; Have good economic benefits, can produce good social benefit.
