Embodiment 1

[0020] according to Figure 1~Figure 3 As shown, the cross cardan shaft hinge device for double steel belt presses of the present invention is mainly composed of frame plate 1, pin shaft 2, bolt 3, hydraulic cylinder 5, plunger 6, pressure plate connecting plate 8, heat insulation plate 9, The heat press plate 10 and the hinge device 4 connecting the plunger 6 and the press plate connecting plate 8 etc., wherein, the hinge device 4 has two axes intersecting (the angle between the axes is between 0° and 90°) and has a distance between The half-shaft 7 constitutes the cross cardan shaft mechanism, and the two half-shafts 7 form the shaft groove connection pair 11 with the plunger 6 and the pressure plate connecting plate 8 respectively, and the two half-shafts 7 can be linearly and rotating movement; the pressure plate connecting plate 8 is fixedly connected with the heat insulation plate 9, and pressed tightly on the hot pressing plate 10; the plunger 6 and the hydraulic cylind...

Embodiment 2

[0022] according to figure 2 , image 3 As shown, the included angle between the axes of the two semi-shafts 7 of the cross cardan shaft hinge device 4 for the double steel belt press in embodiment 1 is 90 degrees.

Embodiment 3

[0024] according to figure 2 , image 3 As shown, the shaft head 12 and notch 13 of the shaft groove connection pair 11 formed by the two half shafts 7 of the cross cardan shaft hinge device 4 for the double steel belt press in embodiment 1, the plunger 6 and the pressure plate connecting plate 8 They are Ω-shaped respectively; the notch 13 and the shaft head 12 of the half shaft 7 are concentrically matched, and can rotate coaxially or move linearly along the axis.

[0025] The working principle of the present invention is as follows:

[0026] In the present invention, the cross cardan shaft hinge device 4 has the function of applying force in both directions, that is, it can apply pressure to the hot pressing plate, see Figure 4 , you can also pull the hot plate in the opposite direction, see Figure 5 .

[0027] When the hot press plate 10 is heated to generate expansion displacement, it will produce expansion displacement along the horizontal plane of the pressing pl...

Abstract

The invention discloses a cross-shaped universal shaft hinging device for a double-steel-strip press. The cross-shaped universal shaft hinging device comprises a framework plate, a pin shaft, bolts, a hydraulic cylinder, a plunger, a pressure plate connecting plate, a thermal baffle, a hot-pressing plate and a hinging device which is used for connecting the plunger and the pressure plate connecting plate, wherein the hinging device comprises a cross-shaped universal shaft mechanism consisting of two half shafts which have crossed axes and are arranged at intervals; the two half shafts are connected with the plunger and the pressure plate connecting plate respectively to form a shaft groove connecting pair; and the two half shafts can perform axial linear movement and rotation around an axis relative to the plunger and the pressure plate connecting plate. With the adoption of the cross-shaped universal shaft structure, the three-dimensional displacement between an oil cylinder and the hot-pressing plate and the rotation of X-Y axes can be realized, so that the force applied to a pressure plate by the oil cylinder and the direction of the force can be accurately controlled, and technologic accurate control is realized. With the adoption of the cross-shaped universal shaft hinging device, the problem that the oil cylinder generates component force on the hot-pressing plate due to expansion displacement of a hot plate is solved, the hydraulic cylinder is prevented from bearing expansion displacement of the pressure plate, and the service life of the hydraulic cylinder is greatly prolonged.

Description

technical field [0001] The invention discloses a cross cardan shaft hinge device for a double-steel belt press, which is an improvement on the structure of the existing hinge device for connecting a plunger and a pressing plate connecting plate for a double-steel belt continuous flat press, and belongs to the technical field of plate processing machinery. Background technique [0002] The hinged device connecting the plunger and the connecting plate of the pressing plate is a very important part of the double-steel belt continuous flat press. The hinged device currently used in the double-steel continuous flat press is a joint thrust bearing, and the joint thrust bearing is located on the frame plate. Between the hydraulic cylinder and the plunger and the connecting plate of the press, the angular movement is realized through the spherical surface between the bearings, and the component force from the pressing plate is solved through the spherical surface between the bearings...
