Abstract
The utility model relates to a novel pressing mechanism in a steel pipe water quenching device. The novel pressing mechanism comprises a fixed support, wherein two support saddles are mounted on the fixed support, an oil cylinder is articulated and mounted on the upper support saddle, the lower end of the oil cylinder is articulated with a swing arm, the lower end of the swing arm is articulated and mounted on the lower support saddle, and the novel pressing mechanism is characterized in that the front end of the swing arm is articulated with a swing rod, a connecting rod is arranged at the joint of the swing arm and the swing rod, one end of the connecting rod is articulated on the swing rod, a plurality of mounting holes are arranged in the swing arm, the other end of the connecting rod is connected with one of the plurality of the mounting holes through a bolt, a V-shaped pressing wheel support frame is articulated at the front end of the swing rod, and a pressing wheel is mounted on the pressing wheel support frame. According to the structure, the effective length and the angle of the whole swing arm can be adjusted; and as for heat steel pipes with different diameters, the pressing wheel can nearly vertically press the heat steel pipe when the swing arm is driven by the oil cylinder to press down, the stress is uniform, the deformation of the steel pipe can be reduced, and the precision and the performance of the steel pipe after quenching can be further improved.
Description
Technical field
The utility model belongs to the metal heat treatmet technical field, particularly relates to the novel hold-down mechanism in a kind of steel pipe water quenching device.
Background technology
Steel pipe water quenching refers to steel pipe is heated to about about 900-1000 ℃, the insulation certain hour, then with water coolant with its a kind of heat treating method that cools down rapidly.In steel pipe water quenching device, the contact roller of hold-down mechanism is corresponding one by one with the swiveling wheel that supporting steel pipe rotates, and compresses the hot steel pipe of water quenching process high speed rotation, makes its rotation steadily, and minimizing is beated and is out of shape.In theory, contact roller should be pressed in vertically that the hot steel pipe that just can make on the steel pipe of rotation in the quenching is stressed evenly, deflection is little.But because the outer diameter of steel pipes specification is different, same set of contact roller can only be realized a kind of steel pipe of specification is vertically depressed, depressing direction for the steel pipe of other specifications all tilts, and diameter differs larger, the angle of inclination is larger, this can make hot steel pipe unbalance stress in the quenching, produces easily distortion, affects precision and performance behind the steel tube quench.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, easy to use, be applicable to the novel hold-down mechanism in the steel pipe water quenching device that the different size steel pipe compresses.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Novel hold-down mechanism in a kind of steel pipe water quenching device, comprise fixed support, two bearings are installed on the fixed support, the hinged oil cylinder that is equipped with on the bearing of described top, the lower end of oil cylinder is hinged with swing arm, the lower end of described swing arm is hingedly mounted on the bearing of below, it is characterized in that: the front end of described swing arm is hinged with fork, described swing arm and fork junction are provided with connecting rod, one end of described connecting rod is hinged on the fork, and described swing arm is provided with several open holess, and the other end of described connecting rod is bolted in several open holess, the front end of described fork is hinged with V-type contact roller bracing frame, on the described contact roller bracing frame contact roller is installed.
Advantage and the positively effect that the utlity model has are: because the utility model adopts technique scheme, namely pass through the conversion of binding site between connecting rod, swing arm, the fork three, thereby adjust length and the angle of whole swing arm, like this for the hot steel pipe of different diameter, the pressure that contact roller can near vertical when the hydraulic oil cylinder driving swing arm was depressed thereon, make it stressed evenly, reduce the distortion of steel pipe, improve precision and the performance of quenching rear steel pipe.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model uses state graph.
Among the figure: 1, fixed support; 2, bearing; 3, bearing; 4, oil cylinder; 5, swing arm; 6, fork; 7, connecting rod; 8, bolt; 9, contact roller bracing frame; 10, contact roller; 11, big steel pipe; 12, little steel pipe.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1 and Fig. 2, novel hold-down mechanism in a kind of steel pipe water quenching device, comprise fixed support 1, bearing 2 and bearing 3 are installed on the fixed support 1, the hinged oil cylinder 4 that is equipped with on the bearing 2 of described top, the lower end of oil cylinder 4 is hinged with swing arm 5, the lower end of described swing arm 5 is hingedly mounted on the bearing 3 of below, the front end of described swing arm 5 is hinged with fork 6, described swing arm 5 and fork 6 junctions are provided with connecting rod 7, one end of described connecting rod 7 is hinged on the fork 6, described swing arm 5 is provided with several open holess 5-1, the other end of described connecting rod 7 is by one in bolt 8 several open holess of connection, and the front end of described fork 6 is hinged with V-type contact roller bracing frame 9, on the described contact roller bracing frame 9 contact roller 10 is installed.
Said structure is by the combination of bolt with connecting rod 7 and swing arm 5 different positionss, the length that corresponding swing arm is different from fork and angle.Like this for the steel pipe of different diameter, by adjusting the binding site of connecting rod 7 and swing arm 5, just can make contact roller 10 being pressed on the hot steel pipe straight down.
The utility model using method: for example when big steel pipe 11 quenches, adjust the bonding station of swing arm 5 and connecting rod 7, by bolt swing arm rightmost side open holes is connected with connecting rod, dwindle length and the angle of swing arm and fork, the direction that makes contact roller 10 compress hot steel pipe is straight down, make hot steel pipe stressed evenly, reduce distortion, improve the rear precision of quenching.
When little steel pipe 12 quenches, adjust the bonding station of swing arm 5 and connecting rod 7, be connected with connecting rod by the open holes of bolt with the swing arm left side, prolong useful length and the angle of swing arm and fork, the direction that makes contact roller 10 compress the little steel pipe that is heated is straight down, make little steel pipe stressed evenly, reduce distortion, improve the rear precision of quenching.
Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
