Detailed description of the invention
As shown in Figures 2 and 3, the main-cylinder stroke displacement compensation device of hydraulic press described in the utility model, forms primarily of upper fluted disc 71, lower tooth disk 72, lower tooth disk rotary drive mechanism (not drawing in figure), an elevating mechanism 73 and a stop pin 74.The fastening lower end being arranged on the master cylinder main piston 31 of hydraulic press of upper fluted disc 71, the angles such as all sides, its lower surface are provided with tooth 711 on several.Lower tooth disk 72 is driven by a rotary drive mechanism can horizontally rotate upper moving beam 4 upper surface that mode is arranged on hydraulic press, and its rotation overlaps with the axis of upper fluted disc; This rotary drive mechanism can adopt hydraulic jack driven unit or driven by servomotor assembly.The upper surface week side of lower tooth disk 72 is provided with several lower tooths 712 corresponding with upper tooth 711.The tooth top end face of upper tooth and lower tooth is plane.Elevating mechanism 73 is made up of two (or four) lift cylinders, and the cylinder part of each lift cylinder is fixed in the frame 1 of hydraulic press, and its tailpiece of the piston rod is then connected with the symmetrical both sides (or position, four angles) of upper moving beam 4.Stop pin 74 is arranged between the master cylinder body of hydraulic press and main piston 31, relatively rotates relative to master cylinder body to prevent main piston 31.
The course of work of the present utility model is as follows:
In the starting stage, as shown in Figure 1, main piston 31 is positioned at upper position-arresting, makes upper moving beam 4 also be in upper position-arresting by elevating mechanism 73, and the upper tooth now going up fluted disc is arranged in the backlash of lower tooth disk, and the lower tooth of lower tooth disk is also arranged in the backlash of fluted disc.The matched moulds stage, first (stroke is a bit larger tham compensation stroke H to drive upper moving beam 4 to decline by elevating mechanism 73, H is lower tooth height), then as shown in Figure 3, drive lower tooth disk to horizontally rotate a fixed angle by rotary drive mechanism and ensure that the upper tooth top end face of tooth and the tooth tip of lower tooth are in the face of neat, then driving main piston to decline makes fluted disc decline, and the upper tooth tooth top end face conflict of upper fluted disc is stayed the tooth top end face of tooth, now also completes mould assembling action.Pressing stage, the rodless cavity injection pressure toward master cylinder is oily to complete compacting action.After compacting action completes, first main piston is driven to rise, when formation of rising slightly exceedes compensation stroke H, make lower tooth disk horizontally rotate a fixed angle and ensure that upper tooth aligns with the backlash of lower tooth, then drive upper moving beam to drive by elevating mechanism to rise, return back to the position of starting stage, now, also complete a work period.
Owing to being upper moving beam in the matched moulds stage, completing down maneuver, main piston does not decline, therefore master cylinder is interior without the need to being filled with hydraulic oil, therefore compared with prior art, hydraulic oil in pressing stage master cylinder just decreases a lot (reducing volume is master cylinder sectional area and the product compensating stroke H), and then decrease when high pressure is suppressed because of energy dissipation that hydraulic oil is caused by compressing, thus reach saving energy, the object of enhancing productivity.
