[0016] The following are only preferred embodiments of the present invention, and do not limit the protection scope of the present invention.

[0017] In the prior art, the hydraulic press, as an auxiliary equipment for sole pressing, requires an operator to load and unload materials. The operator needs to hold the sole workpiece in the equipment's workstation and place it between the upper and lower cylinder bodies to complete the loading; then, start the equipment, press the upper and lower cylinder bodies, and increase the oil pressure of the upper cylinder body 41 and the lower cylinder body 42 to the rated oil pressure; then, keep the oil pressure still for a preset time; finally, complete the sole pressing, separate the upper and lower cylinder bodies, and manually take out the sole workpiece.

[0018] When the hydraulic cylinder assembly inside the hydraulic press is in the pressing operation, the upper cylinder body 41 and the lower cylinder body 42 need to be driven by the pressing drive device to move closer to each other to complete the pressing. However, the manual loading operation has a very high risk. Therefore, most of the existing hydraulic press equipment is equipped with a safety gate, which is driven by an independent drive device and is only opened when loading and unloading. It is controlled by the control device of the equipment, and there is a circuit delay, and the pressing cycle of the whole machine is relatively long.

[0019] Therefore, the inventor proposed the following hydraulic press equipment to improve the safety gate of the hydraulic press, eliminating the use of an independent drive motor for the safety gate, and allowing the safety gate to automatically rise and fall by a linkage structure, thereby reducing the preparation cost of the entire machine, shortening the pressing cycle, and improving production efficiency.

[0020] like Figures 1 to 3 As shown, a double-station hydraulic press for improving a safety gate includes a body 1, a pressing station 10 and a hydraulic cylinder assembly.

[0023] In this embodiment, a chain is used for the flexible chain body 4201. When the upper cylinder body 41 rises for pressing, it also drives the gate body 104 to slide up to complete automatic closing. After the pressing work is completed, the upper cylinder body 41 moves downward, and the gate body 104 moves downward under the action of gravity to complete automatic opening.

[0024] The gate body 104 is driven by the cylinder inside the hydraulic press to realize automatic opening and closing, eliminating the use of an independent driving motor for the safety gate, reducing the preparation cost of the whole machine, eliminating circuit delays, shortening the pressing production cycle of the whole machine, and improving production efficiency.

The safety touch switch unit 1044 sends a braking signal to the control device. The control device controls the hydraulic cylinder assembly to stop running, or pauses the automatic execution of the program, so that the operator can adjust the body position of the sole loading material, thereby improving the usability of the equipment.
