Embodiment 1

[0048] Such as figure 1 , figure 2 , image 3 As shown, a stroke adjustment built-in precision fast press includes a body 1, a workbench 2, a slider 3 and a hydraulic system. The hydraulic system includes a main cylinder 4, a fast cylinder 5, a hydraulic valve group 6, an upper oil tank 7, Lower oil tank 8 and oil pump motor 9, workbench 2, main oil cylinder 4, fast oil cylinder 5, hydraulic valve group 6, upper oil tank 7, lower oil tank 8 and oil pump motor 9 are all fixedly arranged on the fuselage 1, wherein the upper oil tank 7 is fixed It is arranged on the top of the fuselage 1, and the lower fuel tank 8 is fixedly arranged on the bottom of the fuselage 1;

[0049] Such as Figure 4 , Figure 5 and Figure 6 As shown, the master cylinder 4 includes a master cylinder piston rod 31 and a master cylinder body 32, the master cylinder body 32 is fixedly connected with the fuselage 1, the upper end of the master cylinder piston rod 31 extends into the master cylinder bo...

Embodiment 2

[0064] A method of using a built-in precision fast press with stroke adjustment, which is the same as that of Example 1, except that the upper and lower molds are checked in the mold adjustment step E. When the overlap of the upper and lower molds is 1.5mm, the following steps need to be continued First, control the master cylinder piston rod 31 to ascend L (L > 1.5mm), stop the oil pump motor 9; start the stroke adjustment motor again, drive the worm to rotate, and the worm drives the worm wheel 38 to rotate, the worm wheel 38, the limit nut 37 and the adjustment screw 33 Rotate as a whole relative to the main cylinder body 32, the adjusting screw 33 drives the adjusting nut 35 to rotate, and the encoder connected to the encoder connection seat 39 at the upper end of the adjusting screw 33 starts counting, and the adjustment nut 35 descends through PLC calculation and screen display Stop at 1 mm, and this step ends.

Abstract

The invention discloses a stroke regulation built-in precise fast press machine, and an oil cylinder and a use method thereof, belongs to the field of a hydraulic press machine, and solves the problems of low production efficiency, high cost and complicated structure of a slide block regulating mechanism of the existing hydraulic press machine. The oil cylinder provided by the invention comprises a main cylinder piston rod and a main cylinder body, wherein one end of the main cylinder piston rod extends into the main cylinder body; one end extending into the main cylinder body is provided with a cavity; a regulating screw nut is arranged at the upper part of the inner wall of the cavity; the regulating screw nut and the inner wall of the cavity are connected through screw threads; a regulating screw rod is also arranged in the cavity; the lower end of the regulating screw rod extends into the cavity; the middle end passes through the regulating screw nut; the upper end extends out of the main cylinder body; the upper end, extending out of the main cylinder body, of the regulating screw rod is fixedly provided with a worm wheel; the middle end, penetrating through the regulating screw nut, of the regulating screw rod is provided with a key slot; a guide key is arranged on the corresponding regulating screw nut. The press machine, the oil cylinder and the use method have the advantages that the cost can be reduced; the production efficiency is improved; the applicability to various processing processes can be realized.

Description

technical field [0001] The invention belongs to the field of hydraulic presses, and in particular relates to a built-in precision fast press with stroke adjustment, an oil cylinder and a using method thereof. Background technique [0002] When choosing a reasonable die height for a mechanical press, it is necessary to move the slider up and down through a stroke adjustment mechanism (manual or electric). For a large mechanical press, the adjustment mechanism needs a lot of power because the slider is heavy. The distance adopts a mechanical digital display device, and the display is very inaccurate. The nominal force stroke of the slider of the mechanical press is not more than 10mm, which is only suitable for punching and shallow drawing. The nominal force stroke of the hydraulic press is the stroke of the oil cylinder, but the hydraulic press controls the position of the bottom dead center of the slider through the stroke switch. Due to the response error of the electrical ...
