Abstract
The utility model relates to an anti-drop thermal treatment hanging lifting appliance for a crankshaft blank. The lifting appliance comprises more than two U-shaped grooves, wherein an inner reinforcing rib is arranged at the rear of the U-shaped groove, a middle reinforcing rib is arranged between adjacent U-shaped grooves, lifting appliance assembling suspender holes are formed at the periphery of the lifting appliance, end ports at two sides of the U-shaped groove are provided with chamfers, the upper planes and the lower planes of the inlets at two sides of the U-shaped groove are oppositely inclined by certain degree along the direction of the end port, and the upper plane inside the U-shaped groove is vertically and downwardly inclined by certain degree back to the direction of the U-shaped end port. According to the anti-drop thermal treatment hanging lifting appliance for the crankshaft blank, the crankshaft blank is easy to enter the U-shaped groove, after the crankshaft blank enters the U-shaped groove, the reacting force of the gravity of the crankshaft blank is decomposed into a horizontal direction force back to the U-shaped end port, the horizontal direction force is greater than a horizontal sloshing force caused by beat stay or working station suspension in proceeding of a suspension chain and is opposite to the horizontal sloshing force in direction, so that the crankshaft blank avoids falling off in proceeding.
Description
Technical field
The utility model relates to the slip-off preventing thermal treatment of crank shaft blank and hangs suspender.
Background technology
At present, the heat treatment section of domestic forged steel crankshaft blank automatic production line adopts suspension type mostly.So-called suspension type thermal treatment automatic production line refers to by mechanical assembly and is arranged on automatic production line unsettled heat treatment hanger, by forging robot, crank shaft blank is directly suspended on after heat treatment hanger, under electric control system controls stretched wire, turns.Stretched wire, in traveling process, because beat stops or station time-out, easily causes crank shaft blank frequently to rock in the same way and comes off, and causes unnecessary financial loss and potential safety hazard to company.
Utility model content
Technical problem to be solved in the utility model be avoid crank shaft blank advance middle because of beat stop or station suspend cause rock and come off in the same way.
The technical scheme that the utility model addresses the above problem employing is: suspender is hung in a kind of bent axle blank thermal treatment of slip-off preventing, comprises two above U-shaped grooves, and the rear portion of U-shaped groove is provided with inner side stiffening web, is provided with middle part stiffening web between adjacent U-shaped groove; Be provided with suspender erecting jib hole in the surrounding of suspender, described U-shaped groove both sides port is provided with chamfering.
The upper lower plane of described U-shaped groove two side entrances all has certain gradient in opposite directions along port direction.
The upper plane of described U-shaped groove inner side has certain gradient straight down back to U-shaped port direction.
Suspender is hung in the bent axle blank thermal treatment of the utility model slip-off preventing, and U-shaped groove both sides port is provided with chamfering, is beneficial to while forging robot material loading, and crank shaft blank is easy to enter U-shaped groove in the horizontal direction; The upper lower plane of U-shaped groove two side entrances all has certain gradient in opposite directions along port direction, is beneficial to while forging robot material loading, and crank shaft blank in the vertical direction is easy to enter U-shaped groove; The upper plane of U-shaped groove inner side has certain gradient straight down back to port direction, by the reactive force of crank shaft blank gravity has decomposited horizontal direction power back to U-shaped port after putting into the U-shaped groove of suspender at crank shaft blank.This horizontal force be greater than stretched wire advance between because of beat stop or station suspend form horizontal jitter power and opposite direction, thereby avoided crank shaft blank to come off running.
Accompanying drawing explanation
Fig. 1 is the structural representation (attached workpiece) that suspender is hung in the bent axle blank thermal treatment of slip-off preventing of the present utility model;
Fig. 2 is the vertical view that hanger structure is hung in the bent axle blank thermal treatment of slip-off preventing of the present utility model;
Fig. 3 is the left view that in Fig. 2, U-shaped groove A-A dissects position.
In figure: 1.U type groove both sides port chamfering, 2. inner side stiffening web, 3.U type groove two side entrance gradients, the upper plane gradient in 4.U type groove inner side, 5. crank shaft blank, 6. suspender erecting jib hole, 7. middle part stiffening web; 8, U-shaped groove.
Embodiment
As depicted in figs. 1 and 2, suspender is hung in a kind of bent axle blank thermal treatment of slip-off preventing, comprise three U-shaped grooves 8, U-shaped groove is the hanging position of crank shaft blank 5, U-shaped groove is stuck on the main journal of crank shaft blank deep bid end, utilize the diameter of bent axle deep bid end to be greater than the diameter of main shaft, realize the suspension of crank shaft blank.
The rear portion of U-shaped groove 8 is provided with inner side stiffening web 2, is provided with middle part stiffening web 7 between two adjacent U-shaped grooves; Be provided with suspender erecting jib hole 6 in the surrounding of suspender, this suspender erecting jib hole, for suspender is assemblied in to suspension rod, is convenient to fix.
As shown in Figures 2 and 3, the both sides port of U-shaped groove 8 is provided with chamfering 1, and the upper lower plane of U-shaped groove two side entrances is all provided with U-shaped groove two side entrance gradients 3 in opposite directions along port direction, the upper plane of U-shaped groove inner side is provided with the upper planar inverted gradient 4 in U-shaped groove inner side straight down back to U-shaped groove port direction, realize crank shaft blank 5 and be easy to enter U-shaped groove, and after crank shaft blank enters U-shaped groove, the reactive force of crank shaft blank gravity has been decomposited back to the horizontal direction power of U-shaped port and this power be greater than stretched wire advance between because of beat stop or station suspend form horizontal jitter power and with its opposite direction, thereby avoid crank shaft blank to come off running.
Claims (3)
1. a suspender is hung in the bent axle blank thermal treatment of slip-off preventing, it is characterized in that: comprise two above U-shaped grooves, the rear portion of U-shaped groove is provided with inner side stiffening web, is provided with middle part stiffening web between adjacent U-shaped groove; Be provided with suspender erecting jib hole in the surrounding of suspender, described U-shaped groove both sides port is provided with chamfering.
2. suspender is hung in the bent axle blank thermal treatment of slip-off preventing according to claim 1, it is characterized in that: the upper lower plane of described U-shaped groove two side entrances all has certain gradient in opposite directions along port direction.
