Description

  The present invention relates to a material processing technique, and in particular, an extruded bar made of a high-strength aluminum alloy material for cutting the weight of a part in a state of being cut into a unit block workpiece having a predetermined length. The control sleeve (control sleeve), which is an automotive part for supplying oil to the (forging machine) in order and controlling the oil delivery amount, can be produced by forging, while the automotive part that only provided the cutting method The present invention relates to a unit block workpiece processing apparatus for improving productivity and a method for manufacturing the same (workpiece processing device of unit block and the manufacture method method).

  Recently, due to the exhaustion of energy resources due to serious environmental pollution and the rapid increase in demand for automobiles, there is already a fact that regulations on automobile fuel consumption and exhaust gas have been tightened more severely in developed countries, and the development motive for automobile materials is also simple. There is an urgent need in the automotive industry to develop new technologies for improving competitiveness through environmental regulations, exceeding the level of improving fuel efficiency. For this reason, aluminum (Al) casting is mainly used as a lightweight material in the current automotive field. The product was used.

  Aluminum has many advantages such as high heat conductivity, castability and workability, mass production and surface beauty, but it is more expensive than steel materials, and requires improved jointability such as welding, and strength is high. Due to its weakness, automotive forging parts using such aluminum include steering control arm, low arm, plug, parking brake reducer, brake compressor piston, automotive air conditioner compressor piston, There are wash plates, manifolds, socket plates, bolts and nuts, screws, scrolls, and synchronizer sleeves for transmissions.

  In other words, forging is one of metal processing methods for forming a forged extruded bar manufactured into a high-strength aluminum alloy by applying a compressive load into a desired shape, and is a normal forging apparatus used for this purpose. As disclosed in Patent Document 1, Patent Document 2, etc., this comprises a die block on which a die for supporting a material to be processed in common and a ram on which a tool is mounted, The ram is reciprocated to the die block side by using a hydraulic or electric motor to form the material into a form corresponding to the tool shape, and the die block is provided with a transfer for transferring the material. The material is then transferred in sequence to the die by this transfer, and formed in stages by each tool mounted on the ram, and finally the desired shape by the last tool. It is possible to manufacture the automotive forged parts described above as.

  As a result, not only the weight reduction of some parts of the car as described above, but also a step forward, now all parts of the car use high-strength aluminum alloy material to reduce the overall weight of the car As a result, research to improve fuel consumption has been actively carried out, and as a part of this, a control sleeve for controlling the oil delivery amount has been produced using a high-strength aluminum alloy material. It was.

  Here, as shown in FIG. 1 attached, one end 101 of the control sleeve 100 is connected to a pinion, and the other end 102 is fitted to a drive flange of the plunger, and the rotational movement of the control pinion is transmitted to the plunger to move up and down. It is an automotive part that increases or decreases the amount of oil delivered while exercising.

  However, as described above, the control sleeve 100, which is an automobile part that controls the amount of oil delivered, cannot be manufactured by a forging apparatus, and is manufactured only through a cutting apparatus. It had the disadvantage that the productivity decreased.

  That is, when supplying a forging bar made of a high-strength aluminum alloy to a forging apparatus, this supply causes the roller to wind the extruded bar, and supplies it to the transfer. In this case, When the supplied extruded bar is cut, the cut portion of the extruded bar having a relatively low strength is not smooth and is crushed, and the control sleeve 100 cannot be manufactured using the extruded bar.
