Description

[0001] FULL THREAD BOLT MANUFACTURING APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a computer-aided bolt forming apparatus, and more particularly, to a computerized bolt forming apparatus capable of automatically and rapidly forming a bolt having a thread on an entire circumferential surface thereof.

Generally, a bolt has a hexagonal or quadrangular shape and is composed of a head portion which can be rotated by a spanner or the like, and a thread portion into which a nut is inserted after being fastened.

However, depending on the application, there is a bolt in which a thread is formed on the entire bolt without a head, which is called a computer bolt, and a computer bolt used for suspending an object inserted into an anchor bolt of a concrete ceiling is called a desk bolt or a hanger bolt do.

In using the computer bolt, the anchor is inserted into the appropriate position of the concrete slab, and the metal bar is fastened with one end of the bolt so that a certain length is maintained. And a nut is fastened to the other end to fix the installed object.

In manufacturing a general bolt including such a bolt, conventionally, a round bar was put into a molding machine to form a thread on the outer circumferential surface.

However, the conventional bolt forming apparatus is disadvantageous in that the turning direction of the round bar is the same as the discharging direction of the bolt, so that the working speed is lowered and the productivity is accordingly lowered.

In addition, since the worker has to manually supply the round rods to be supplied one by one, the workability and productivity are lowered, the formed bolts are loaded in an unaligned state, and the worker takes an unnecessary time to bundle them and align them .

The manner and structure of opening / closing the second discharge hole 82 by the stopper 83 are sufficient by using various conventional methods and structures, and therefore, a detailed description thereof will be omitted.

The swash plate 84 has an upper end connected to the second exhaust hole 82 and a lower end sloped downward.

When the stopper 83 opens the second discharge hole 82, the bolt 92 disposed in the stop 81 is moved to the swash plate 84 through the second discharge hole 82 by gravity, .

The alignment stacker 85 is installed at the lower end of the swash plate 84 so that the computational bolts 92 discharged through the second discharge hole 82 and the swash plate 84 are aligned in the same direction, Is the place to be.

When the second sensor 86 senses the bolt 92 while the bolt 92 is inserted into the stopper 81 through the transfer pipe 70, (83) opens the second discharge hole (82).

The bolt 92 inserted in the stop 81 is rotated through the second discharge hole 82 and the swash plate 84 and aligned in the same direction in the alignment tray 85, .

The present invention may further include a structure for reusing the cutting oil supplied through the cutting oil supply pipe 40, that is, a storage vessel 41, a pump 42, a recovery pipe 43, and the like.

The storage container 41 stores coolant.

The pump 42 serves to supply the coolant of the storage container 41 to the coolant supply pipe 40.

One end of the return pipe 43 is connected to the lower part of the housing 10 and / or the lower part of the loading part 80, and the other end is connected to the storage container 41.

Therefore, the cutting oil supplied to the first rotary roll 21 and / or the second rotary roll 22 through the cutting oil supply pipe 40 is collected at the lower portion of the housing 10.

Alternatively, the cutting oil moves along the transfer pipe 70 together with the bolts 92 to the sorting stacker 85 in detail.

The collected cutting oil is recovered to the storage container 41 through the recovery pipe 43 and re-supplied to the cutting oil supply pipe 40 through the pump 42.

This makes it possible to reuse coolant, reduce environmental pollution, and reduce costs.
