Abstract
The utility model discloses an oil hydraulic system for producing a heat pipe, which comprises an oil pressure pump, wherein an oil outlet end of the oil pressure pump is connected with a P port of a three-position four-way valve, a B port of the three-position four-way valve is connected with a first end of an oil hydraulic cylinder, an A port of the three-position four-way valve is connected with a second end of the oil hydraulic cylinder, and a T port of the three-position four-way valve is connected with an oil return end of the oil pressure pump. The oil hydraulic system has the beneficial effect that an oil way is transformed, so that the phenomenon of bad products because an oil cylinder of the whole oil system cannot return pressure cannot occur, and the yield rate is effectively increased.
Description
Technical field
The utility model relates to a kind of production heat pipe pressurized oil system, belongs to field of mechanical technique.
Background technique
Heat pipe need to seal the one end in process of production, generally adopts pressurized oil system to seal.Existing pressurized oil system as shown in Figure 1, the oil outlet end of oil pressure pump 1 is connected with three-position four-way valve 3, described three-position four-way valve 3 is connected with hydraulic jack 2.Oil circuit process of the prior art is: when pressurizing valve E gets when electric, hydraulic oil is fuel-displaced from the oil outlet end 11 of oil pressure pump 1, and hydraulic oil enters through the P mouth of three-position four-way valve 3; When back-pressure valve F gets when electric, hydraulic oil is fuel-displaced from the oil outlet end 11 of oil pressure pump 1, P mouth through three-position four-way valve 3 enters, enter into hydraulic jack 2 from the B mouth, at this moment, need to reset by the brute spring in the hydraulic jack 2 during back pressure, and because the elastic force of spring is inadequate, often causing can not back pressure, thereby causes the bad of product.
The model utility content
The purpose of this utility model is to solve above-mentioned technical problem, proposes a kind of production heat pipe pressurized oil system.
The purpose of this utility model will be achieved by the following technical programs:
A kind of production heat pipe pressurized oil system, comprise an oil pressure pump, the oil outlet end of described oil pressure pump is connected with the P mouth of a three-position four-way valve, the B mouth of described three-position four-way valve is connected with the first end of an oil hydraulic cylinder, the A mouth of described three-position four-way valve is connected with the second end of oil hydraulic cylinder, and the T mouth of described three-position four-way valve is connected with the oil revolving end of oil pressure pump.
The beneficial effects of the utility model are mainly reflected in: by to the transformation of oil circuit so that whole oil-way system can owing to oil cylinder can not back pressure produce the bad phenomenon of product, effectively not increase rate of good product.
Description of drawings
Fig. 1 is prior art pressurized oil system schematic diagram.
Fig. 2 is the utility model pressurized oil system schematic diagram.
Embodiment
The utility model provides a kind of production heat pipe pressurized oil system, as shown in Figure 2, comprise an oil pressure pump 1, the oil outlet end 11 of described oil pressure pump 1 is connected with the P mouth of a three-position four-way valve 3, the B mouth of described three-position four-way valve 3 is connected with the first end 21 of an oil hydraulic cylinder 2, the A mouth of described three-position four-way valve 3 is connected with the second end 22 of oil hydraulic cylinder 2, and the T mouth of described three-position four-way valve 3 is connected with the oil revolving end 12 of oil pressure pump 1.
Pressurized oil system oil circuit working procedure of the present utility model under the brief description:
When three-position four-way valve 3 pressurizing valve E hold electricly, hydraulic oil is fuel-displaced from the oil outlet end 11 of oil pressure pump 1, through the oil-feed of P mouth, the second end 22 from oil hydraulic cylinder 2 after fuel-displaced by the A mouth of three-position four-way valve 3 enters, then after fuel-displaced from the first end 21 of oil hydraulic cylinder 2, the B mouth that enters into three-position four-way valve 3 is got back to the T mouth, from oil revolving end 12 oil returns of oil pressure pump 1.
When three-position four-way valve 3 back-pressure valve F hold electricly, hydraulic oil is fuel-displaced from the oil outlet end 11 of oil pressure pump 1, through the oil-feed of P mouth, first end 21 from oil hydraulic cylinder 2 after fuel-displaced by the B mouth of three-position four-way valve 3 enters, then after fuel-displaced from the second end 22 of oil hydraulic cylinder 2, the A mouth that enters into three-position four-way valve 3 is got back to the T mouth, from oil revolving end 12 oil returns of oil pressure pump 1.
Whole oil circuit can automatic back pressure, can be owing to can not back pressure not causing the bad of product, greatly increase work efficiency and the up-to-standard rate of product.
The utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technological schemes of forming all drop within the protection domain of the present utility model.
