A kind of hydraulic press
One. technical field
The utility model relates to hydraulic press.
Two. background technology
The machinery that is used for the processing of flanged plate blank now has two kinds, a kind of is that hammering freely forges machinery, it is by the impulsive force of weight freely falling body, break into the flanged plate blank with burning red iron block, the vibrations of this kind mechanicalness noise are big, and the blank allowance of producing is big, not of uniform size, the cost height, operation is many, and efficient is low; Another kind is a friction press, drives slide block by screw rod and down moves, and with the punch forming of high temperature strand, friction press self heaviness, the manufacturing cost height need be done the very high cushion cap of bearing capacity and support, and expense is big, and noise and vibrations are arranged in the process.
Three. summary of the invention
The purpose of this utility model is to provide a kind of cost low in order to overcome the deficiencies in the prior art, and the efficient height is easy to operate, a kind of hydraulic press that is used for the moulding of flanged plate blank of shockproof and noise.
Task of the present utility model is achieved in that hydraulic press comprises frame, hydraulic system, cooling system, pressurization oil cylinder, patrix and counterdie, the pressurization oil cylinder is contained in the frame upper end, and connect with patrix, cooling system connects with upper die and lower die, it is characterized in that the mobile oil cylinder that the frame lower end is equipped with travelling table and is connected with travelling table, a plurality of counterdies are placed in above the travelling table.
The utility model is easy and simple to handle, makes simply, and the production efficiency height, cost is low, can not produce noise and vibrations.

Fig. 2 is the A-A cutaway view of Fig. 1.
Five. the specific embodiment
As Fig. 1, shown in Figure 2, pressurization oil cylinder (2) is equipped with in frame (1) upper end, travelling table (4) is placed on frame (1) lower end, patrix (3) connects with pressurization oil cylinder (2), and counterdie (9) connects with travelling table (4), and mobile oil cylinder (5) connects with travelling table (4), hydraulic system (6) connects with pressurization oil cylinder (2) and mobile oil cylinder (5), and cooling system (7) connects with patrix (3) and counterdie (9).As Fig. 1, when forcing press is worked, earlier high temperature strand (8) is placed on above the left and right sides counterdie (9) on the travelling table (4), patrix (3) is connected cooling system (7) with counterdie (9) and is cooled off, operation hydraulic system (6), the logical oil in pressurization oil cylinder (2) top drives patrix (3) and moves down, with strand (8) extrusion forming, oil cylinder (2) bottom logical oil then pressurizes, driving patrix (3) rises, operate hydraulic system (6) this moment, the logical oil in mobile oil cylinder (5) the right drives travelling table (4) toward moving left, when the right counterdie (9) is aimed at patrix (3), mobile oil cylinder (5) stops, the logical oil in oil cylinder (2) top pressurize this moment toward pressing down, simultaneously the former strand (8) that is molded on the lower-left mould (9) that presses is taken away, relay the strand of lastblock high temperature, strand extrusion forming on bottom right mould this moment (9), pressurization oil cylinder (2) drives patrix (3) and rises, mobile oil cylinder (5) left side is connected oil and is driven travelling table (4) toward moving left, continuous action so repeatedly, every function of realization hydraulic press.Because travelling table (4) is gone up the extrusion forming and the picking and placeing simultaneously of blank of strand and is operated, and has shortened the production time, has improved efficient.
