Embodiment Construction
[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] The device of the present invention is arranged between the transmission side of the two intermediate rollers and the universal joint shaft. The shaft head circumference of the intermediate roller transmission side is provided with convex ribs symmetrical along the diameter. The universal joint shaft has a certain range of expansion and contraction, and the related to the amount of lateral movement. The universal joint shaft is connected with the sleeve cup 4 to provide power, and the two sleeve cups 4 are clutched and connected to the corresponding intermediate roller 10 respectively.
[0020] refer to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , the structure of the device of the present invention is that a joint sleeve cup 4 is correspondingly arranged between the upper and lower intermediate rollers 10 on the tran...

The invention discloses an automatic tripping gear applied to clamping of a drive shaft. Connecting shaft sleeve cups are respectively arranged between upper and lower middle rollers arranged on a drive side and universal connecting shafts of the upper and lower middle rollers; the front end of each connecting shaft sleeve cup is provided with upper and lower sleeve cup pinholes in a manner of being vertical to the axes of the middle rollers; the end of a piston rod of a hydraulic cylinder of a clamper on each side is connected with upper and lower chucks; a short ejector rod and a long ejector rod are respectively horizontally mounted on the inner side of each chuck; spring sleeves are respectively arranged in two sleeve cup pinholes of each connecting shaft sleeve cup; the tip of one end of each spring sleeve is connected with one long ejector rod in a supporting manner; the other end of each spring sleeve is connected with a locating block by a spring; each spring sleeve is provided with a key slot which is sleeved with a guide key in the sleeve cup pinhole; a back key slot of the spring sleeve is provided with a groove along the chordwise direction; the groove is located in match with a protruding rib of each middle roller. The automatic tripping gear disclosed by the invention can be used for guaranteeing reliable connection during rolling and horizontal movement of the middle rollers and also releasing the connection when the middle rollers are replaced.
Description
technical field [0001] The invention belongs to the technical field of metallurgical machinery and equipment, and in particular relates to an automatic decoupling device for transmission shaft clamping. Background technique [0002] The existing 1100mmHC six-roller molybdenum plate reversible rolling mill is used for reversible cold rolling of a single molybdenum plate, which can roll the molybdenum plate with a maximum thickness of 2.5mm and a maximum width of 1030mm into a thickness of 0.3mm after cold rolling. -2mm finished molybdenum plate. [0003] The design difficulties of the above-mentioned 1100mmHC six-high molybdenum plate reversible rolling mill are: 1) The thickness of the rolling plate is small, resulting in a small diameter of the work roll, so that the drive of the work roll cannot guarantee sufficient rolling torque; 2) The drive of the intermediate roll is selected, The intermediate roller needs to transmit torque and also be able to move laterally in the ...
