Definitions

  • the invention relates to plastering press machines shaping metal sheet part without causing breaking and leaving fold tracks by generating force between to opposite cylinders in a mould.
  • the invention relates to plastering press machines providing cold shaping to the material located between the upper mould and lower mould by applying force by upper mould by means of compression cylinder, and relates to a pre-filling valve for free vertical motion of the upper mould and associated plate, medium 4 stage pump and medium electrical engine providing electricity generation in electrical drivers, change of rotation direction of 4-stage pump by electrical engine to provide motion of compression cylinders in downward direction and adjustment of plate falling down rate, generation of pressure by means of electrical engines of 4 stage pump after closing of pre-filling valve by means of upper valve block.
  • the presses in the existing system consist of several valve groups such as direction control valve, speed adjustment valve and pressure adjustment valve etc. and therefore, problems such as maintenance and spare parts are experienced and furthermore, troubleshooting becomes more difficult and the recovery of occurring faults takes longer time.
  • the presses are usually starting point of production and for that reason, the fault occurring initially causes stop of the production line. The reasons indirectly cause increase of costs and more time to be wasted in production processes. Electrical engines in the existing press embodiments operate regardless of performance of work by press. And this causes oil heating and consumption of unnecessary energy.
  • the invention relates to plastering system of double impact hydraulic presses, in other words, gradual single mould and having single operation effect and used for plastering from bottom to top. Almost all of the existing plastering operations are conducted from top to bottom by means of conventional method and are expensive production and the highest plastering speed is 11-12 mm/sec. This invention provides reaching speed of 25-30 mm/sec and eliminates all pot pins and thus economical, quick and perfect plastering from bottom to top (reverse) is realized.
  • the abstract page of the invention reads that the invention is a hydraulic press method designed and realized to produce industrial products or kitchen tools from light metals such as copper, brass, bronze and aluminium, and chromium-nickel alloy and iron, steel base all fine sheet materials which can be cold shaped by use of closed hydraulic circuit in contrary to open hydraulic circuits used in hydraulic presses in general.
  • This method is a method of plastering (deep traction) - shaping (forming) conducted by fully closing moulds in order to produce high quality products, and it discloses an embodiment providing pressing by means of providing hydraulic power and speed required by both operations by means of close circuit special hydraulic system formed on a stabile (inflexible) hydraulic press.
  • the purpose of the invention is to provide motion of cylinders by use of engine cycling and rotation capability of 4 stage pump (pump/engine) used for compression and cushion cylinder without use of direction control valve, speed adjustment or rate valve etc. In other words, the pressure loss occurring in such valves is eliminated and direct use of energy is ensured.
  • One purpose of the invention is to provide energy generation by means of opposite direction rotation of electrical engine and use of compression cylinder through operation of plastering cylinder by engine function of pump during plastering work.
  • the weight of the press platform is benefited and the energy generated by weight during free fall by help of operation of hydraulic pump like an engine is converted into work and thus instead of electricity consumption, electricity is generated.
  • Another purpose of the invention is to provide consumption electricity by electrical engines of the new system only during operation of the press.
  • the energy loss occurring in hydraulic systems causes heating of fluid, which leads, in turn, to reduction of viscosity.
  • Reduced viscosity causes distortion in adjustment or difficulty in position control. Precise position and force control capability is developed by means of elimination of them.
  • Another purpose of the invention is to use the coolant and equipment as heating does not occur. And this is another energy gaining. Since there is no heating problem in hydraulic oil, capacity of oil tank is reduced in proportion to volumes of cylinders. Since operation life of fluid will increase in smaller volumes and because of heat, the environment protection is provided.
  • a further purpose of the invention is to use the location design advantage in presses by help of reduced volume of oil tanks.
  • several valves and members are used to control position and location, which causes both monetary loss and spare part problems.
  • High number of members makes it difficult to troubleshoot and thus recovery of faults takes longer time.
  • the new system consists of less members and valves as it has been developed through the best solution is the simplest product.
  • Another purpose of the invention is to control pressure, speed and position by rotation and torque control of electrical engine, and thus all settings have been simplified and provide easy troubleshooting and recovery of occurring faults in shorter time period. Moreover, estimation of life of sealing members is provided by help of traceability of rotation number of pump on monitor. And this provides saving in service costs.
  • Another purpose of the invention is to provide accurate traceability by help of calculation of rotation number of pumps by encoder used in the engines, measurement of torque quantity and position data ruler. Thus it is easy to discover the faults occurring on the mould surface and therefore necessity to spotting presses is eliminated.
  • a further purpose of the invention is to control each cylinder separately and putting the plane position of the platform under the load under control by means of increase of number of pumps in press embodiments where number of cylinders is increased. Thus the life of material being pressed as well as mould and bearing is extended.
  • Figure 1 is a schematic view giving illustrative picture of 4-stage pumps and valve blocks providing energy saving in plastering press being subject of the invention. Reference Numbers

Rotation, torque data received from engine (10, 12) and pump pressure position and ruler (50) position data are monitored on the display (14) and thus over-resisting regions on the surface of the moulds (90, 91 ) are recorded. This provides operation of the press like an spotting press.
  • the energy generated by reverse pushing of the cushioning cylinder (31 ) by force applied from compression cylinder (30) through engine driving the 4-stage pump (20) for the compression operation provides operation of 4-stage pump (22) as engine and operation of electrical engine (12) like a generator and thus regenerative electrical generation is provided by means of electrical drivers.
