Definitions

  • the present invention relates to a press unit with integrated press cylinder.
  • the cylinder integrated in the press unit enables simplified operation with regard to the use of external hydraulic units, pipes, fittings and other hydraulic installations.
  • Pressing processes have developed significantly thanks to the automation of such processes, allowing for more accurate and scaling operations. These automation processes have provided greater production efficiency and precision at the expense of a larger and more complex trimming structure.
  • pressing operations are carried out in different industries safely from the point of view of operator protection and at higher speeds with minimal losses.
  • the energy cost is high and the functionality of the machines is achieved with a larger dimensioning.
  • patent document PI9203875 reference is made to an injection molding machine comprising a machine frame, an injection assembly coupled with the frame, a press assembly also coupled with the frame, a mold assembly assembly coupled with the assembly. and a mold holder assembly secured to the press assembly by the mold assembly.
  • the mold holder assembly includes first and second mold holder units that define a mold cavity when they are placed in a closed condition.
  • the mold holder assembly additionally includes alignment members which ensure correct alignment between the first and second mold holder units when a condition is closed, the first mold holder unit includes an injection assembly for engagement with the injection assembly.
  • the mold mounting assembly includes first and second mold mounting devices, securing the first and second mold holder units, respectively, to the press assembly.
  • the ground mounting assembly additionally includes a sensor which indicates the correct alignment of the mold holder assembly in relation to the press assembly the press assembly moves the first and second mold holder units between a closed condition and an open condition in which they are located. mutually separated the displacement of the first milling unit by the press assembly engages the unit with the injection assembly.
  • Patent document PI9304305 refers to an electrically operated hydraulic press suitable for the production of lime and / or cement stabilized ground-based bricks, with the aim of reducing the cost of building popular housing and community equipment. capacity for production above 5,000 bricks per day, and suitable for installation in medium-sized production units, characterized by its upper (01) and lower (03) beams, support columns (02), support bases ( 07), actuator mounting plates (05) and mounting plates (06), die support beams and base (04) (10), movable die (18) and three linear hydraulic actuators, one pressing (32) and two demolition (31) coupled to a hydraulic unit. The compaction pressure on the face of each brick is generated by the force transmitted by the hydraulic actuator.
  • the pressing is started by moving the support (34), fixed die (35), movable cover (36) and linear hydraulic actuator (52) coupled to a hydraulic unit from above.
  • pressing is initiated by actuating the hydraulic control (50) by moving the compaction assembly upwards from below. until the maximum working pressure is reached, then the opening of the movable cover (36) occurs and the bricks are expelled through the actuation of the hydraulic actuator, which thus completes its course.
  • Patent document PI 0403811 relates to a pressing unit comprising an interdependent pressure rail (4) minus two parallel rods (2) mounted slidingly between two end positions via a horizontal upper support (1) , through a connecting means (3), an elastic compression means (8) being disposed between said support (1) and said pressure rail (4) to probably keep the latter in its most widely spaced position from said horizontal upper support (1), defined by interdependent stops (9) of said rods (2).
  • Said connecting means (3) comprises a support surface (3f) against the upper side of said upper support (1) and at least two deformable jaws (3a) symmetrically arranged in relation to the longitudinal geometric axis of said passage (3d). ), said jaws (3a) traversing two relative passages (1b) of said support (1) and each comprising a support surface (3b) against the lower surface of said support (1).
  • PI 0710220 refers to a lower-acting single-acting lower drive press capable of saving energy, saving space, and performing well-balanced high-precision conformability.
  • a press is provided capable of shortening a forming stroke, reducing overall readiness, accurately correcting the deflection of the slider or dies with the aim of optimizing the adhesion of the dies to a workpiece, and performing pressure equalization of a retainer.
  • undulating a lower drive press includes a forming press unit which in turn includes a lower die located at the bottom of an undulating ring retainer fixedly disposed on a bed, and a drive mechanism disposed within the bed to lift or lower a slider supporting the lower die, a slider raised or lowered by a drive mechanism loaded on the side of a crown, a die holding press assembly incorporating an upper die provided with a fastening part of a workpiece in cooperation with the curl retainer at its peripheral edge, and a device applying a gripping force Measuring the upper die behind after the last slider stage of the die holding press unit and the upper die for improvements in forming accuracy.
  • Figure 1 illustrates a longitudinal section view of the pressing unit of the present invention
  • Figure 2 illustrates a longitudinal section view of the fender motor mount of the present invention
  • Figure 3 illustrates a longitudinal section view of the movable cylinder head of the present invention.
  • the pressing unit comprises a movable cylinder head (1), a sinker platform (2), a pump piston (3), a movable cylinder portion (4), a fixed cylinder portion (5), a trim cap portion (6), an axle portion (7), gear means (8, 9), a pump cap (10), an axle bushing (11) and a motor support (12) shown in Figure 2.
  • the pressing unit comprises a plunger diameter of about 185mm, for working stroke up to 160mm.
  • the maximum operating pressure of the pressing unit comprises about 340 bar and a set of return units (not shown) for restoring the pressing unit to the end of an operating cycle.
  • THE pressing unit operates with a motor provided under a motor flange ( Figure 2) which comprises a 15CV electric motor and 352.0 rpm controlled by an solenoid valve.
  • the preferred pump of the present invention comprises a flow rate of 7.85 cm 3 / rotation and a torque of 4.88N, m.
  • the plunger head (1) comprises a recess assembly (13), fasteners (14) and a head projection (15) on a plate (16); the head projection still has an annular segmentation (17).
  • the engine drives an axis parallel to the rod that drives an oil pump which is located inside the piston; which pumps the fluid from the upper side to the lower side of the system causing the cup (movable cylinder) to advance, thereby realizing the pressing effort.
  • the system can be modified to operate in other positions such as horizontal.
  • the advantage of the invention is to dispense with external hydraulic units, pipes, fittings and other hydraulic accessories; and the system is automated, that is, both the cylinder and the electrovalve are controlled by logical unit.
