The hold-down device comprises a cylinder base (12) disposed on a frame (1) of the mobile lifting automatic quenching machine, and guide bases (2) disposed on two the frame (1) on two sides of the cylinder base (12). A cylinder (3) is disposed on the cylinder base (12). A piston rod connector (4) of the cylinder (3) is connected with an upper support frame (7). A guide bar (10) is disposed on each guide base (2). The lower end of each guide bar (10) is fixedly connected to the upper support frame (7). The hold-down device has the advantages that quenching deformation of workpieces can be controlled, quenching quality of the workpieces is guaranteed, intensity of labor in calibrating the workpieces after quenching is decreased, workpiece productivity is improved, a mechanism of the device is simple, and manufacturing, assembly and disassembly are all convenient.
Description
Technical field
The utility model relates to a kind of movable lifting type automatic quenching machine special pressing device.
Background technology
The especially long and thin workpiece of workpiece is in free state when quenching, do not have extraneous strength to control its distortion, thus for the calibration behind the workpiece quenching causes certain technical difficulty, to a certain extent to productivity and quenching the form of quality considerable influence.
Summary of the invention
The purpose of this utility model provides a kind of workpiece quenching of can controlling is out of shape, and guarantees the workpiece quenching quality, reduces the labour intensity that workpiece is calibrated after quenching, a kind of movable lifting type automatic quenching machine special pressing device of boosting productivity.
For addressing the above problem, the technical scheme that the utility model is taked is: a kind of movable lifting type automatic quenching machine special pressing device, comprise the oil cylinder seat that is arranged on the movable lifting type automatic quenching machine frame and the guide holder that is positioned on the oil cylinder seat machine frame at two sides, on the described oil cylinder seat oil cylinder is installed, the piston rod connecting joint of oil cylinder connects the upper support framework, described guide holder is provided with guide rod, and the lower end of guide rod is fixedly connected with the upper support framework.The effect of guide rod is to guarantee that the upper support framework is in horizontality all the time, and relative piston rotation not, oil cylinder is by piston rod connecting joint push-and-pull upper support framework, workpiece pressing, thereby can control the workpiece quenching distortion, guarantee the workpiece quenching quality, reduce the labour intensity of workpiece calibration after quenching, boost productivity.
As further improvement of the utility model, described upper support framework is provided with the oil cylinder Connection Block, and the oil cylinder Connection Block connects the piston rod connecting joint by bearing pin.Simple in structure, making and dismounting are all more convenient.
As further improvement of the utility model, described upper support framework bottom connects material-pressing rack, and described material-pressing rack relatively upper support framework is up and down.Binder is erected shock absorption, prevent that the upper support framework from directly pressing workpiece and instantaneous dynamics more greatly to the workpiece injury, further guarantee the workpiece quenching quality.
Further improve as of the present utility model, described upper support framework is connected mandrel with material-pressing rack and connects, and cover has spring on the described mandrel.Utilize the mode of spring housing mandrel, not only simple in structure, and the good buffer effect of spring.
In sum, the beneficial effects of the utility model are: not only can control the workpiece quenching distortion, guarantee the workpiece quenching quality, reduce the labour intensity of workpiece calibration after quenching, improve the productivity of workpiece, and mechanism be simple, it is all more convenient to make dismounting.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Movable lifting type automatic quenching machine special pressing device as shown in Figures 1 to 4, comprise the oil cylinder seat 12 that is arranged on the movable lifting type automatic quenching machine frame 1 and the guide holder 2 that is positioned on oil cylinder seat 12 machine frame at two sides 1, oil cylinder 3 is installed on the described oil cylinder seat 12, the piston rod connecting joint 4 of oil cylinder 3 connects upper support framework 7, described guide holder 2 is provided with guide rod 10, and the lower end of guide rod 10 is fixedly connected with upper support framework 7.Described upper support framework 7 bottoms also are connected with material-pressing rack 11, and described material-pressing rack 11 relatively upper support framework 7 moves up and down.
Guide holder 2 and guide rod 10: guide holder 2 is symmetricly set on the frame 1 of oil cylinder 3 both sides, vertically has through hole on the guide holder 2, and guide rod 10 passes through hole and is fixedly connected with upper support framework 7, so guide rod 10 is can only in the vertical direction up and down.
The working process of the utility model movable lifting type automatic quenching machine special pressing device is: oil cylinder 3 piston rod connecting joints 4 promote upper support framework 7 and material-pressing rack 11 downwards, upper support framework 7 drives guide rod 10 and moves up and down, guide rod 10 guarantees that again upper support framework 7 can not rotate relative to oil cylinder 3 around bearing pin 6, material-pressing rack 11 begins to contact the workpiece 14 that is placed on the workseat 13 after being moved downward to certain distance, this moment, oil cylinder 3 continuation piston rod connecting joints 4 promoted upper support frameworks 7 downwards, and because the effect of spring 9 between upper support framework 7 and the material-pressing rack 11, material-pressing rack 11 can not reach the dynamics of optimal pressure workpiece 14 immediately, but increase to press slowly the power of workpiece 14, thereby avoid the injury that overexerts workpiece 14 is caused because of moment.
The case of implementation described in the utility model only is better case study on implementation of the present utility model, is not to limit practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be as technology category of the present utility model.
