Problems solved by technology

However, since the above-mentioned stroke positioning devices have only one precise positioning effect, they can only control a single stroke, and cannot perform positioning of different strokes in multiple times, so that the scope of application of the hydraulic machine is restricted, especially the high-efficiency and high-quality production.

Embodiment 1

[0024] Please combine Figure 1 ~ Figure 3 As shown, the stroke positioning device 10 is arranged on the upper end of the piston rod 1a of the lower hydraulic cylinder of the hydraulic machine, the number of the adjusting nuts 11 is two, and the limit block 12 is a pair, forming a two-stage stroke limit form. When the upper hydraulic cylinder drives the upper punch 4 to press down, the limit block 12 is driven out by the drive mechanism 13, and the lower hydraulic cylinder shrinks down so that the bottom end surface of the outer adjustment nut 11 is in contact with the upper limit surface of the limit block 12, Realize short stroke limit, press ( figure 2 Shown in is the positioning position where the upper punch 4 is pressed against a powder 5, and 7 shown in the figure is the lower punch of the lower hydraulic cylinder); when the upper hydraulic cylinder drives the upper punch 4 to lift up, the limit The block 12 is driven and retracted by the driving mechanism 13, and is ...

Embodiment 2

[0026] Please combine Figure 4 ~ Figure 6 As shown, the difference from Embodiment 1 is that the stroke positioning device is located at the upper end of the piston rod 1b of the hydraulic cylinder on the hydraulic press, and is used for two pressings of two different powders, that is, when the limit block 12 is stretched out, the upper end The hydraulic cylinder drives the upper punch 4 to press down until the outer layer adjustment nut 11 and the stop block 12 are in contact with each other to achieve a short-stroke pre-compression of the powder 5 ( Figure 5 That is the positioning position where the pre-pressing is completed), then the upper hydraulic cylinder drives the upper punch 4 to lift up, and after the limit block 12 is retracted, the second powder 5' is added to the die 3, and the pressure is pressed again until the inner layer The end face of the bottom of the adjusting nut 11 is offset against the upper end face of the cylinder body of the upper hydraulic cylin...

Embodiment 3

[0028] Please combine Figure 7 ~ Figure 9 As shown, the difference from Embodiment 1 and Embodiment 2 is that the stroke positioning device is located at the lower end of the piston rod 1a of the lower hydraulic cylinder of the hydraulic press, and can also control the loading position of the die 3 through two different strokes. Two different powders are added into the machine, and then the upper punch 4 is driven down by the upper hydraulic cylinder to realize the pressing of two different powders.

Abstract

The invention discloses a stroke positioning device for a powder forming hydraulic press. The stroke positioning device is arranged at the end of a piston rod of a hydraulic cylinder of the hydraulic press, corresponding adjusting nuts are limited by at least one group of limit blocks and height difference formed by more than two adjusting nuts which are sleeved layer by layer, so that different strokes of a piston of the hydraulic cylinder of the hydraulic press can be positioned for multiple times, and the requirements of multilayer products pressed by various powder are met. In addition, positioning distances can be steplessly adjusted within a certain range by adjusting the distance between the adjusting nuts.

Description

technical field [0001] The invention relates to a hydraulic press, more specifically, to a stroke positioning device for a powder forming hydraulic press. Background technique [0002] The patent for invention with the publication number CN 1371802A discloses a powder forming hydraulic press. The hydraulic press is equipped with a stroke positioning device consisting of a limit adjustment nut and a lock nut on the upper and lower hydraulic cylinders and the punch to adjust the stroke of the piston and the The stroke of the punch is limited and adjusted to improve the dimensional accuracy and density of the powder compact. However, since the above-mentioned stroke positioning devices have only one precise positioning effect, they can only control a single stroke, and cannot perform positioning of different strokes in multiple times, so that the scope of application of the hydraulic machine is restricted, especially the high-efficiency and high-quality production. Powder comp...
