[0020] 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.

[0021] Example 1, please refer to Figure 1-Figure 3 A cylinder-driven safety column for a frame-type hydraulic press includes a supporting device, a sensing and driving device connected to one side of the supporting device, the supporting device includes a safety supporting column 6 and a supporting seat 9; the sensing and driving device includes a safety device mounting plate 4, a sensing optical axis, and a cylinder 2.

[0022] A box-type linear bearing 1 3.1 and a box-type linear bearing 2 3.2 of the same structure are respectively arranged at the upper end and the lower end of the safety device mounting plate 4.

[0023] A cylinder 2 is arranged in the middle of the safety device mounting plate 4, and the cylinder 2 is movably connected to the middle end of the side of the support seat 9 through a piston rod 11. A proximity switch mounting plate 1 is arranged at the bottom of the safety device mounting plate 4, and a proximity switch 10 is arranged on the proximity switch mounting plate 1. The proximity switch 10 is used to monitor the retraction of the sensing optical axis 2 5.2.

[0024] The sensing optical axis includes a sensing optical axis 1 5.1 and a sensing optical axis 2 5.2. The box-type linear bearing 1 3.1 is connected to the sensing optical axis 1 5.1 by a movable sleeve; the box-type linear bearing 2 3.2 is connected to the sensing optical axis 2 5.2 by a movable sleeve. The sensing optical axis 1 5.1 and the sensing optical axis 2 5.2 move back and forth horizontally in the box-type linear bearing 1 3.1 and the box-type linear bearing 2 3.2 respectively. The other ends of the sensing optical axis 1 5.1 and the sensing optical axis 2 5.2 are respectively connected to the upper and lower ends of the side of the support seat 9. The top and bottom of the support seat are provided with through holes 12 for the safety support column 6 to pass through.

[0025] A spring 8 is arranged above the support seat 9 and surrounds the safety support column 6. A positioning ring 7 is arranged at the end of the spring 8 and fixed to the safety support column 6. The safety support column is inserted into the support seat 9, the spring 8, and the positioning ring 7 in sequence. The positioning ring 7 is fixed to the safety support column 6 by bolts; the outer diameter of the positioning ring 7 is larger than the outer diameter of the through hole 12. Finally, the support seat 9 and the optical axis move back and forth in the horizontal plane driven by the cylinder 2.

[0026] Example 2, based on Example 1, please continue to refer to Figure 1-Figure 3 In the process, the safety device mounting plate is fixedly installed on the side beam of the hydraulic press, the safety column switch is turned on first, and the cylinder 2 pushes the safety support column 6 into the hydraulic press. The safety support column 6 is suspended in the machine, and the hydraulic press slider begins to descend. After descending to the set height, the safety support column 6 supports the slider. Since the positioning ring 7 is fixedly set on the safety support column 6, and the outer diameter of the positioning ring 7 is larger than the outer diameter of the through hole 12, and the spring 8 has a buffering effect, the safety support column plays the role of safely supporting the slider. After the relevant personnel complete the operation and leave, the safety column switch is turned off, and the cylinder 2 drives the safety support column 6 to leave the hydraulic press. After the proximity switch 10 detects that the optical axis 5 has completely retreated to its position, it feedbacks information, and the hydraulic press continues to operate.

[0027] In this embodiment, the proximity switch 10 is a prior art and will not be described in detail. Among various types of switches, there is a component that has the ability to "sense" objects approaching it - a displacement sensor. The proximity switch uses the sensitive characteristics of the displacement sensor to approaching objects to achieve the purpose of controlling the switch on or off. When an object moves toward the proximity switch and approaches a certain distance, the displacement sensor will "sense" and the switch will operate. Automatically controlling the safety column through pneumatic components not only protects the safety of the operator, but also reduces the workload of the operator.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
