[0025] The soundproof cover 8 is fixedly sleeved on the outside of the oil pump 6, and the material of the soundproof cover 8 is polyester fiber material; by setting the soundproof cover 8, when the workpiece is compressed, the workpiece is placed directly under the extrusion plate 3 and the oil pump 6 is started, so that the oil pump 6 can continuously deliver the hydraulic oil in the oil tank 11 to the inside of the oil cylinder 2 through the delivery pipe 9. At this time, the soundproof cover 8 can isolate the noise generated by the oil pump 6 when it is working, so as to avoid the oil pump 6 from generating loud noise when working for a long time, causing noise pollution around the machine body 1, thereby improving the noise reduction effect of the hydraulic press when it is working.

[0026] One end of the delivery pipe 9 is fixedly sleeved on the top of the oil cylinder 2, and the delivery pipe 9 is made of metallic copper material; by setting the delivery pipe 9, when the workpiece is extruded, the throttle valve 10 can limit the flow of the hydraulic oil inside the delivery pipe 9, thereby avoiding the problem of damage to the delivery pipe 9 when the pressure of the hydraulic oil in the delivery pipe 9 is high, thereby improving the stability of the hydraulic oil flow.

[0027] The filter mechanism 13 includes a sealing cover 131, which is fixedly sleeved on one end of the oil drain pipe 12, and a filter screen 132 is fixedly sleeved inside the sealing cover 131; by setting the filter mechanism 13, when the hydraulic oil is circulated and recovered, the filter screen 132 can filter the hydraulic oil inside the oil drain pipe 12, so as to avoid the problem that the metal debris inside the oil drain pipe 12 causes wear on the inner wall of the oil cylinder 2 when the hydraulic oil circulates, thereby improving the service life of the oil cylinder 2, that is, improving the service life of the hydraulic press.

[0028] The limiting mechanism 14 includes a limiting sleeve 141, which is fixedly sleeved inside the body 1, and the limiting sleeve 141 is movably sleeved inside the limiting sleeve 141 to be connected to a limiting column 142, and one end of the limiting column 142 is fixedly connected to the top of the extrusion plate 3; by setting the limiting mechanism 14, when the workpiece is extruded, the limiting sleeve 141 can limit the position of the extrusion plate 3 moving up and down through the limiting column 142, thereby avoiding the problem of tilting of the extrusion plate 3 when moving up and down, thereby improving the stability of the extrusion plate 3 when moving up and down.

[0032] The working principle of the single-column servo hydraulic press provided by the utility model is as follows:

[0033] Step 1: First, when the workpiece is compressed, the workpiece is placed directly under the extrusion plate 3 and the oil pump 6 is started, so that the oil pump 6 can continuously deliver the hydraulic oil in the oil tank 11 to the inside of the oil cylinder 2 through the delivery pipe 9. At this time, the soundproof cover 8 can isolate the noise generated by the oil pump 6 when it is working, so as to avoid the problem of noise pollution around the machine body 1 caused by the large noise generated by the oil pump 6 when working for a long time, thereby improving the noise reduction effect of the hydraulic press when working. When the workpiece is extruded, the throttle valve 10 can limit the flow of the hydraulic oil in the delivery pipe 9, so as to avoid the delivery pipe 9 from being blocked when the hydraulic oil flows under a large pressure. The problem of damage is solved, thereby improving the stability of hydraulic oil flow. When the hydraulic oil is circulated and recovered, the filter 132 can filter the hydraulic oil in the drain pipe 12, so as to avoid the problem of metal debris in the drain pipe 12 causing wear on the inner wall of the cylinder 2 when the hydraulic oil circulates, thereby improving the service life of the cylinder 2, that is, improving the service life of the hydraulic press. When the workpiece is extruded, the limit sleeve 141 can limit the position of the extrusion plate 3 moving up and down through the limit column 142, thereby avoiding the problem of tilting of the extrusion plate 3 when moving up and down, thereby improving the stability of the extrusion plate 3 when moving up and down;

[0034] Step 2: When the hydraulic press is working, start the rotating motor 151 so that the rotating motor 151 can drive the fan blades 152 to rotate quickly. At this time, the fan blades 152 can quickly discharge the airflow inside the chassis 4 to the outside of the chassis 4, thereby achieving the heat dissipation effect of the chassis 4, thereby improving the heat dissipation speed of the hydraulic press. When the chassis 4 is dissipating heat, the filter cover 16 can filter the airflow entering the inside of the chassis 4, so that the dust in the airflow can be blocked by the filter cover 16 to the outside of the chassis 4, thereby improving the cleanliness of the inside of the chassis 4. When the body 1 is closed, pull the closed door 172 so that the closed door 172 can be separated from the magnet column 171, so that the body 1 is opened. When the body 1 is closed, flip the closed door 172 so that the magnet column 171 can adsorb and fix the closed door 172 on the front of the body 1, thereby bringing convenience to the opening and closing of the body 1.
