Abstract
The utility model discloses a double handle small press which relates to the technology of a pressing machine. The utility model has a main structure that one end of a high pressure oil cavity in a box body is connected with hydraulic unidirectional valves, a low pressure hand pump and low pressure handles, and the other end is connected with the hydraulic unidirectional valves, the high pressure hand pump and high pressure handles. The utility model overcomes a defect of the high pressure handles of existing single handle press, such as multiple operation. The utility model is an ideal product for replacing existing small presses and has the advantages of simple structure, convenient operation, and wide pressure ranges.
Description
The utility model relates to press technologies.
Superconductor and nano material all are the important object of contemporary science research, and they all be unable to do without the powder compacting technology in preparation, especially in the laboratory research stage, be unable to do without small-sized press especially.The sample of prepared in laboratory, not only wide in variety but also fragmentary, the pressure of in addition suppressing sample will change often, and the amplitude of Bian Huaing is bigger sometimes, therefore requires press small-sized, and it is easy to be reliable to operate.
At present the domestic existing small-sized press is a monolever, four power posts, but the screw rod of an oscilaltion is housed in the middle of the top board, the compacting sample comes directly towards the upper surface by bottom face under the screw rod and press and exerts pressure and suppress.But because the screw rod face area is little, screw thread is gapped in addition, so the face of exerting pressure is difficult for parallelly up and down, it is also unbalanced to pressurize, and causes the sample quality of compacting not ideal enough.When especially suppressing the strip sample, above defective is more outstanding.Existing besides small-sized press is a monolever, for press also can be used when the needs high pressure, to have to design pressure ratio (pressure/lever operated power that the press top produces) very big, this makes that motion of press top is slow, when the big material of compacting compression ratio, very inconvenience.
The purpose of this utility model is bigger in order to overcome existing small-sized press monolever pressure ratio design, and the motion of press head waits shortcoming slowly, designs a kind of convenient and reliable operation, and pressure limit is wide, the dual-handle small-sized press that the sample quality that suppresses is good.
Below in conjunction with accompanying drawing, the utility model is illustrated it.
Accompanying drawing 1 is an external structure of the present utility model;
Accompanying drawing 2 is internal hydraulic pressure system diagrams of the present utility model.
Structure of the present utility model is seen accompanying drawing 1, is that the side at casing (3) is equipped with low pressure handle (4), and opposite side is equipped with high pressure handle (6); The front of casing (3) is equipped with oil return valve (5); Be equipped with press top (1) on casing (2), rear side is equipped with Pressure gauge (2); Positive four jiaos of places are equipped with respectively four power posts (7) at casing (3), and top board (8) is fixed on four power posts (7) by nut.
Hydraulic system of the present utility model is seen accompanying drawing 2, all is contained in the casing (3), and a termination hydraulic one-way valve (9) of high-voltage oil cavity (14) connects low pressure manual pump (13), again connected tank (10) again; Another termination hydraulic one-way valve (11) of high-voltage oil cavity (14) connects high-pressure hand pump (12), again connected tank (10) again; The external low pressure handle of low pressure manual pump (13) (4), the external high pressure handle of high-pressure hand pump (12) (6); High-voltage oil cavity (14) also takes back fuel tap (5), again connected tank (10).
During the utility model work, sample to be pressed is placed on the end face of press head (1),, only needs operation low pressure handle (4), can finish the compacting of sample rapidly as need low pressure compacting sample; When needs compacting high pressure sample, can use low pressure handle (4) earlier, make the press head rise to pressing position rapidly, and carry out precompressed, operate high pressure handle (6) carries out the high pressure compacting then.
The utility model has the advantages that avoided the multi-pass operation of the high pressure handle of monolever press in periods of low pressure, the sample quality of compacting is good, pressure limit is wide.The utility model is simple in structure, and easy operating is the desirable upgrading products that substitute existing small-sized press, estimates to have fabulous application prospect.
