Abstract
The invention relates to a hydraulic lock for a large hot-forging die hydraulic circuit. The hydraulic lock comprises a return cylinder hydraulic circuit and is characterized in that a hydraulic lock A formed by a cartridge valve is arranged on the return cylinder hydraulic circuit, and a hydraulic lock B formed by a check valve is arranged on the hydraulic circuit disposed between the hydraulic lock A and a return cylinder. The hydraulic lock has the advantages that the hydraulic lock B is further arranged on the hydraulic circuit disposed between the hydraulic lock A and the return cylinder so that double locking is formed; the hydraulic lock B is formed by the forged check valve so that the hydraulic lock is simple in structure, can bear large-tonnage hydraulic circuit oil pressure and is ensured to be safe and reliable.
Description
Technical field
The present invention relates to a kind of large-scale hot upsetting mould hydraulic circuit, particularly a kind of large-scale hot upsetting mould hydraulic circuit hydraulic lock.
Background technique
The hydraulic circuit mould deadweight of heavy-duty forging die is larger, back pressure is larger during the slide block backhaul, the hydraulic lock that is comprised of cartridge valve is set on the kicker cylinder hydraulic circuit of hot-forging die, utilizes this cartridge valve to the locking of kicker cylinder oil circuit, avoid slide block to descend suddenly and cause serious security incident.Still have certain potential safety hazard but lock by cartridge valve merely, safety coefficient is lower.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of simple in structure, large-scale hot upsetting mould hydraulic circuit hydraulic lock that safety coefficient is high.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of large-scale hot upsetting mould hydraulic circuit hydraulic lock, comprise the kicker cylinder hydraulic circuit, and its innovative point is: be provided with the hydraulic lock A that is made of cartridge valve on the described kicker cylinder hydraulic circuit; On the hydraulic circuit between hydraulic lock A and the kicker cylinder, also be provided with the hydraulic lock B that is consisted of by one-way valve.
Further, described forging one-way valve is that one-way valve is forged in hydraulic control.
The invention has the advantages that: utilize hydraulic lock B also is set on the hydraulic circuit between hydraulic lock A and the kicker cylinder, thereby form double locking; Hydraulic lock B adopts and forges one-way valve, and is simple in structure, and can bear large-tonnage hydraulic circuit oil pressure, guarantees safe and reliable.
Description of drawings
Fig. 1 is the large-scale hot upsetting mould hydraulic circuit hydraulic schematic diagram of the present invention.
Embodiment
As shown in Figure 1, comprise kicker cylinder 1, kicker cylinder 1 is connected with hydraulic station by the kicker cylinder hydraulic circuit, is provided with the hydraulic lock A2 that is made of cartridge valve at the kicker cylinder hydraulic circuit.
On the hydraulic circuit between hydraulic lock A2 and the kicker cylinder 1, also be provided with the hydraulic lock B that one-way valve 3 consists of.In the present embodiment, this one-way valve 3 is Pilot operated check valve, and adopts the 45# forging to make the housing that forms, and guarantees that it can bear oil pressure larger in the hydraulic circuit.
Working principle: when kicker cylinder 1 is descending, opens by little pump control and to forge one-way valve 3, by behind the hydraulic lock A2 hydraulic oil being discharged, double insurance is avoided slide block to descend suddenly and is caused potential safety hazard again.
Claims (2)
1. one kind large-scale hot upsetting mould hydraulic circuit hydraulic lock comprises the kicker cylinder hydraulic circuit, it is characterized in that: be provided with the hydraulic lock A that is made of cartridge valve on the described kicker cylinder hydraulic circuit; On the hydraulic circuit between hydraulic lock A and the kicker cylinder, also be provided with the hydraulic lock B that is consisted of by one-way valve.
2. large-scale hot upsetting mould hydraulic circuit hydraulic lock according to claim 1 is characterized in that: described forging one-way valve is that one-way valve is forged in hydraulic control.
