DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figure 1-2The bearing device of a frame-type hydraulic press shown in the figure comprises a top beam 200, a support frame 100 fixed on both sides of the bottom end of the top beam 200, and a hydraulic platform 300 located below the top beam 200. The top end of the top beam 200 is fixedly connected with a hydraulic cylinder 201 that passes through the bottom end of the top beam 200. The bottom end of the hydraulic cylinder 201 is provided with a hydraulic rod 202 that can be extended and retracted in the hydraulic cylinder 201. A hydraulic oil tank and a hydraulic pump are also arranged next to the support frame 100 to transport hydraulic oil in the hydraulic cylinder 201 so that it can drive the hydraulic rod 202 to be extended and retracted, thereby hydraulically processing the workpiece placed on the hydraulic platform 300. A bearing pad 101 is fixedly provided at the bottom end of the support frame 100. The setting of the bearing pad 101 can support the bottom end of the support frame 100 and increase the contact area with the ground, so that the force on the ground is more uniform, thereby avoiding the situation where the ground is concentrated due to force and is broken or dented, which helps to improve the safety and protection of the frame-type hydraulic press. In a preferred embodiment, rectangular through holes 308 for penetrating the outer wall of the support frame 100 are provided at both ends of the hydraulic platform 300. The provision of the rectangular through holes 308 enables a sliding connection to be formed between the hydraulic platform 300 and the outer wall of the support frame 100, so that the support frame 100 can play a limiting and guiding role in the lifting and lowering movement of the hydraulic platform 300, thereby maintaining the stable lifting and lowering movement of the hydraulic platform 300 in the vertical direction. An installation slot is provided at the top of the hydraulic platform 300, and a reinforcement platform 309 is fixedly installed in the installation slot. The top of the reinforcement platform 309 is located at the same horizontal plane as the positioning of the hydraulic platform 300. The reinforcement platform 309 is made of hard steel. Placing a workpiece in the area of ​​the reinforcement platform 309 for hydraulic processing can improve the load strength of the hydraulic platform 300 supporting the workpiece, avoid damage to the hydraulic platform 300, and extend its service life. In addition, the upper surface of the hydraulic platform 300 and the upper surface of the reinforcement platform 309 are maintained at the same horizontal height, so that the workpiece can be placed stably.

[0020] A lifting mechanism capable of adjusting the height of the hydraulic platform 300 is provided between the bearing pad 101 and the hydraulic platform 300. The lifting mechanism can not only support the hydraulic platform 300, but also adjust the height of the hydraulic platform 300, so that the hydraulic platform 300 can realize hydraulic operation of workpieces of various heights, which is helpful to improve the adaptability of the frame type hydraulic press. The lifting mechanism includes: a bidirectional lead screw 301 horizontally arranged between the bearing pad 101 and the hydraulic platform 300, and a nut seat 302 is threadedly sleeved on the outer wall of the bidirectional lead screw 301. The nut seat 302 can be driven by the rotation of the bidirectional lead screw 301. The female seat 302 moves horizontally along its outer wall to drive the support rod 303 to rotate. The rotation of the support rod 303 changes the vertical height of the support rod 303, so that the hydraulic platform 300 can be lifted and the height of the hydraulic platform 300 can be adjusted. At the same time, due to the self-locking effect between the two-way screw 301 and the nut seat 302, the two-way screw 301 cannot be driven to rotate by the movement of the nut seat 302, so the support rod 303 can keep the position fixed after rotation, so that the stable support of the hydraulic platform 300 can be achieved. One end of the lead screw 301 is fixedly connected to an inner hexagonal handle 306. The setting of the inner hexagonal handle 306 not only allows the operator to hold the outer wall of the inner hexagonal handle 306 to drive the bidirectional lead screw 301 to rotate, but also allows the operator to insert a hexagonal wrench into the inner hexagonal hole at the end of the inner hexagonal handle 306 for clamping, so that the bidirectional lead screw 301 can be driven to rotate with the assistance of the hexagonal wrench, which is more flexible and convenient to operate, has high adaptability, and better meets the use requirements. The other end of the bidirectional lead screw 301 is fixedly connected to a limiting head 307. The setting of the limiting head 307 cooperates with the inner hexagonal handle 306. , to limit the two ends of the bidirectional lead screw 301, so that the nut seat 302 cannot be separated from the bidirectional lead screw 301, increasing the safety of use. The side wall of the support frame 100 is provided with a vertical through hole 102 for the end of the hydraulic platform 300 to pass through. The opening of the vertical through hole 102 can facilitate the end of the bidirectional lead screw 301 to extend, thereby facilitating the operator to drive the bidirectional lead screw 301. At the same time, the vertical through hole 102 can also meet the bidirectional lead screw 301 being driven by the support rod 303 to move up and down when rotating, avoiding the position of the bidirectional lead screw 301 being restricted and causing the overall operation to fail.A hinge seat 304 is fixedly connected to the hydraulic platform 300 and the opposite side of the bearing pad 101. A support rod 303 is hinged between the hinge seat 304 and the nut seat 302. The ends of the support rod 303 located above and below the nut seat 302 can be hinged to the bottom end of the hydraulic platform 300 and the top end of the bearing pad 101 through the hinge seat 304, so that the ends of the support rod 303 can rotate. At the same time, the other end of the support rod 303 is rotatably plugged with a pin fixed to the side wall of the nut seat 302, thereby meeting the requirement that both ends of the support rod 303 can rotate. , so that when the nut seat 302 moves, the support rod 303 can be driven to rotate, thereby adjusting the height of the hydraulic platform 300. The side of the articulated seat 304 away from the bidirectional screw 301 is fixedly connected with a reinforcing plate 305, and the reinforcing plate 305 is fixedly connected to the outer wall of the hydraulic platform 300 or the bearing pad 101 at the corresponding position. The setting of the reinforcing plate 305 can increase the contact area between the support rod 303 and the hydraulic platform 300 and the bearing pad 101, which helps to improve the protective effect between the support rod 303 and the hydraulic platform 300 and the bearing pad 101. ;

[0021] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
