Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

Embodiment 1: Please refer to Figures 1 and 2. A safety fixing device for a movable crossbeam of a hydraulic press includes a base 1 and a fixed rod 2. The base 1 is welded and fixed to the upper crossbeam, and the upper end of the fixed rod 2 is welded. It is fixed on the movable cross beam; a locking device 3 is provided inside the base 1, so that the bottom end of the fixed rod 2 extends into the inside of the base 1 and is movable connected with the locking device 3.

Embodiment 2: On the basis of Embodiment 1, the locking device 3 includes a frustum, and holes and grooves communicating with each other are provided on the inside of the frustum. In this embodiment, there are four holes and four grooves. The holes and slots are interconnected, so that the fixing rod 2 is located in the middle of the interconnected holes and slots, and the outside of the frustum is slidingly connected to the inner wall of the base 1. A third locking device 3 is formed between the locking device 3 and the inside of the base 1. An oil chamber 4 and a second oil chamber 5, and a first oil port 8 and a second oil port 9 are provided on the side wall of the base 1, and the first oil port 8 is connected with the first oil chamber 4; The second oil port 9 is connected with the second oil chamber 5 .

Embodiment 3: On the basis of Embodiment 2, a locking ball 6 is provided in each slot. The locking ball 6 can move left and right in the slot, such as moving to the right, to lock it. One side of the ball 6 approaches the central axis along with the locking device, and locks the fixed rod 2. If it moves to the left, the side of the locking ball 6 approaches and moves away from the inclined wall of the hole groove along with the locking device. Fixed rod 2.

Embodiment 4: On the basis of Embodiment 2, a limit end 7 is provided at the upper end of the base 1 for a limit when the frustum slides up. When oil is fed into the first oil port 8, the oil passes through the first oil port 8. When the oil port 8 enters the first oil chamber 4, the locking device rises inside the base 1 due to the bottom oil pressure. During the lifting of the locking device, each locking ball in the locking device 6. Approach the central axis and block the fixed rod 2. If the system suddenly loses power or the operator changes the mold, the movable beam will not fall suddenly.

Embodiment 5: Based on Embodiment 2, when the movable beam is operating normally, when the second oil port 9 supplies oil, the first oil port 8 discharges oil, and the oil enters the second oil through the second oil port 9 When the cavity is 5, the locking device is lowered inside the base 1 due to oil pressure, and the locking ball 6 moves away from the central axis under the action of oil pressure, so that the fixed rod can move freely without being locked. Ball 6 limit.

The above are only preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person familiar with the technical field can, within the technical scope disclosed by the present utility model, implement the present utility model according to the present utility model.
