Problems solved by technology

The "pneumatic and manual dual-purpose press" recommended by Chinese patent CN201333809Y can meet the requirements of the operator to choose between manual operation and pedal operation. However, the complex structure and troublesome operation are its shortcomings. For details, please refer to No. 3 of the patent specification Page lines 3-9
[0005] To sum up, in the patent schemes that are not limited to the above-mentioned jack hydraulic presses, there is no technical enlightenment that can be operated by both manual and pedal operation.

Embodiment 1

[0027] See figure 1 ,Should figure 1 A frame 1 is provided, which is composed of an upper beam 11, a lower beam 12, a first longitudinal arm 13, a second longitudinal arm 14 and a workpiece rack 15, and the upper and lower beams 11, 12 correspond to each other up and down, The upper end of the first longitudinal arm 13 is fixedly connected with the right end of the upper beam 11, and the lower end of the first longitudinal arm 13 is fixedly connected with the right end of the lower beam 12, and the upper end of the second longitudinal arm 14 is fixedly connected with the left end of the upper beam 11, and The lower end of the second longitudinal arm 14 is fixedly connected to the left end of the lower crossbeam 12, so that the frame 1 is formed by the upper and lower crossbeams 11, 12 and the first and second longitudinal arms 13, 14 parallel to each other longitudinally to form a structure similar to Chinese characters. The "mouth"-shaped structure, the workpiece frame 15 is...

Embodiment 2

[0056] See Figure 5 , in the present embodiment, the small pump overpressure drain channel 311h is moved toward the direction of the oil return channel 311g of the working cylinder ( Figure 5 The state shown is shifted to the left), and the small pump overpressure drain passage 311h is connected with the small pump inlet and outlet oil passage 311e, and the valve body 31 is provided with a small pump overpressure discharge passage connected with the small pump overpressure discharge passage 311h. The oil return hole 311s of the oil passage, the oil return hole 311s of the small pump overpressure oil release passage communicates with the oil storage tank 33 . Compared with the oil return passage 311i in Embodiment 1, this oil passage structure communicates with the oil return passage 311g of the working oil cylinder, the overpressure oil discharge passage 311h of the small pump, and the fast and slow speed control valve chamber 3161. The oil return passage 311i is only connec...

Abstract

The invention relates to a jack hydraulic press and belongs to the field of pressure machines. The jack hydraulic press comprises a frame consisting of an upper transverse beam, a lower transverse beam, a first longitudinal arm, a second longitudinal arm, a rack, a working oil cylinder; a hydraulic pump station and an operating mechanism, wherein the hydraulic pump station comprises a valve body, a pump body and an oil storage tank, the valve body is arranged on one side, opposite to the second longitudinal arm, of the first longitudinal arm, the pump body is matched with the valve body and the oil storage tank is connected with the valve body. The jack hydraulic press is characterized in that the operating mechanism comprises a pressing handle base, a pressing handle, a pedal arm, a pull rod and a pull rod return spring, one end of the pressing handle base is hinged with the valve body, the middle part of the pressing handle base is hinged with the pump body, the other end of the pressing handle base is hinged with the upper end of the pull rod, the lower end of the pull rod is hinged with the pedal arm, one end of the pedal arm is hinged with the first longitudinal arm, the other end of the pedal arm is a free end and forms a pedal, the pressing handle is matched with the pressing handle base in a pluggable manner, the upper end of the pull rod return spring is fixedly arranged on the first longitudinal arm and the lower end of the pull rod restoring spring is fixedly arranged on the pull rod. Since the pump body of the hydraulic pump station can be operated through not only the pressing handle but also the pedal arm, the selection flexibility is high.

Description

technical field [0001] The invention belongs to the field of press machinery, and in particular relates to a jack hydraulic press. Background technique [0002] Compared with large-scale hydraulic presses (also known as hydraulic presses), jack hydraulic presses can play a role in filling gaps. The specific performances are wide adaptability to application sites, small size, convenient operation, and low cost. However, large or medium and small hydraulic presses are the opposite. They need to be equipped with corresponding hydraulic stations, have a large overall volume, poor adaptability to the place of use, high equipment costs, and difficult investment and management. It is precisely because the jack hydraulic press has the aforementioned advantages that are incomparable to large or even small and medium-sized hydraulic machines, so it can be used not only in factory production lines, construction sites, electromechanical equipment maintenance industries, vehicle maintena...
