Embodiment Construction
[0019] Such as Figure 1-2 A heavy-duty hydraulic mold shifting arm is shown, which includes a roller device clamped by two support plates 1. The two support plates 1 are fixedly connected by fastening bolts 25. The roller device includes a roller device connecting the two support plates 1. The support shaft 18 is sleeved with a bearing 26 on the outer circumference of the support shaft 18, and the outer circumference of the bearing 26 is sleeved with a roller 2, and a hydraulic support system is arranged between the bearing 26 and the roller 2. The hydraulic support system includes a spring 23 installed in the axial installation hole 20 of the support shaft 18. One end of the spring 23 is connected to the bottom of the installation hole 20, and the other end is connected to a sealing ball 21. The sealing ball 21 is connected to the oil injection hole 22. The oil injection hole 22 is located at In the center of the sealing plug 29, the sealing plug 29 is airtightly connected t...

The invention discloses a heavy-load hydraulic die moving arm which comprises a roller device clamped by two supporting plates in a matched mode. The two supporting plates are fixedly connected through a fastening bolt, the roller device comprises a supporting shaft connected with the two supporting plates, a bearing sleeves the periphery of the supporting shaft, a roller sleeves the periphery ofthe bearing, and a hydraulic supporting system is arranged between the bearing and the roller. The hydraulic supporting system is arranged between the bearing and the roller, on the basis that the supporting shaft provides supporting force, a mounting hole of a one-way oil injection structure is formed, pressure cavities are formed between the mounting hole and an oil groove as well as the bearingand the roller, and the roller of the hydraulic structure is not directly in contact with the bearing, so that the bearing is prevented from being abraded; and the weight of a die moving under pressure can be greatly increased, and the application range of the die moving arm is expanded.
Description
technical field [0001] The patent of the present invention relates to the technical field of mold transfer arm, in particular to a heavy-duty hydraulic mold transfer arm. Background technique [0002] The main function of the mold transfer arm is to move the mold to or out of the processing lathe. Since the mold is often heavy, it will wear and deform the inside of the mold transfer roller during long-term use. How to avoid this contact wear caused by heavy pressure is the basic The object of research by those skilled in the art. [0003] Chinese Utility Model Patent No. 201520987664.1 discloses a fixed mold-moving arm and a punch press with a fixed mold-moving arm, including a long mold-moving arm body, one end of the mold-moving arm body is connected to the mounting seat, and the mold-moving The end of the arm body away from the mounting seat is provided with a stopper structure, and the upper part of the mold transfer arm body is provided with an upwardly opening install...
