Abstract
Description
The present invention relates to a jig apparatus for extracting a mold, and more particularly to a jig apparatus for extracting a mold from a die or a punch using a screw principle after fixing the projecting end surface of the die with a magnet switch.
Generally, the bolt manufacturing process is performed in the order of forging, wire rolling, heat treatment, plating, and shipment of the wire-shaped raw materials. In the first process, the forging machine is replaced.
The forging machine is provided with dies and punches as shown in FIGS. 9A and 9B. In the forging process, the dies are coupled to the dies in a maximum of four stages (four) Cutting is performed in the first stage, preforming is performed in the second stage (nose side chamfering), and bolt molding is performed in the third and fourth stages.
Depending on the case, it is sometimes necessary to change the mold twice or three times a day, and the mold replacement time is about 2 hours to 2 hours and 30 minutes, and thus the production amount is decreasing.
The mold demolding process and the mold clamping process will be briefly described below.
First, the mold disassembling process is performed by performing a step of loosening the bolt, extracting the cutting knife and the clamp of the die and the punch of the die, manually removing the mold of the die and the punch and then removing the oil, Is performed.
In the mold clamping step, a step of inserting the prepared mold into the die is performed, a step of tightening the primary bolt of the die is performed, a step of tightening the bolt after the cutting knife and the clamp are fastened to the punch, A step of adjusting the length of the die and the center of the punch die and then a step of tightening the second bolt is performed and a step of visually confirming through the production of a test sample is performed, And then performing the producing step.
The standard of the mold is slightly different, but the basic weight corresponds to about 6 ~ 10kg each. In order to replace the mold, the mold is manually removed and inserted. Although the weight of the mold is not so heavy, it is difficult to carry out the work by the operator, and since the mold is grease, it is slippery and there is always a risk of safety accident due to the fall of the mold have.
Also, it is very difficult to remove the used mold, and now the mold is picked up by the force of the person or the forceps. Due to the nature of the forging operation, the molds are very tightly bonded and can not be separated easily. Therefore, they are hammered by a rubber hammer several times and then separated.
In order to solve such a problem, the present invention aims to provide a jig device for extracting a die from a die or a punch using a screw principle after fixing the projecting end face of the die with a magnet switch.
In addition, the present invention provides a die extracting jig device for fixing a die-cutting jig device by using a fixing magnet switch for fixing the die itself, and for providing a structure capable of continuous operation with one device .
It is another object of the present invention to provide a jig device for extracting a mold for allowing two or more extracts to proceed simultaneously as needed.
The jig for extracting a mold according to an embodiment of the present invention includes a plurality of mold engaging recesses to which a plurality of molds are coupled and is coupled to one side of a die coupled to the mold engaging recess to expose an end of the mold, The mold can be extracted from the mold engaging groove.
As an embodiment related to the present invention, there is provided an apparatus for extracting a mold, comprising: a main support body having a pair of guide rails spaced apart from each other by a predetermined distance, And the upper and lower guide rails provided in the direction opposite to the direction in which the main support body is fixed to the sub support body, the engaging portions provided on each of the bent surfaces of the sub support body, And a mold extracting unit coupled to be slidably movable.
As an embodiment related to the present invention, a mold extracting portion includes a movable body having a through hole formed at its center portion, a movable bar coupled to allow forward or backward movement along the through hole, and a movable bar coupled to one end face of the movable bar facing the die And a handle coupled to an end of the moving bar.
As an embodiment related to the present invention, a first screw thread is formed along the outer periphery of the moving bar, and a second screw thread is formed on the inner side of the through hole so as to be engaged with the first screw thread, have.
In an embodiment related to the present invention, a plurality of engagement holes are formed at regular intervals in a pair of guide rails, and a plurality of spring plungers, which are engaged with some of the engagement holes, And the rear surface, respectively.
As an embodiment related to the present invention, the mold extracting device may be formed of a magnet switch for mold extraction and a magnet switch provided at the upper end of the mold extracting magnet switch.
As an embodiment related to the present invention, the coupling portion may be formed of a magnet switch for fixation and a magnet switch provided at the upper end of the fixation magnet switch.
The present invention has the effect of securing the operator's safety by facilitating the work process by fixing the tool with the magnet switch on the projecting end face of the mold and extracting the mold from the die or punch using the screw principle .
Further, according to the present invention, the dies themselves are fixed by using a magnet switch for fixing to fix the die extraction jig device, and by providing a structure capable of continuous operation with one device, Can be improved.
Further, according to the present invention, it is possible to simultaneously perform two or more extracting operations as needed, thereby shortening the working time and improving the working efficiency.
As a whole, the present invention can shorten the mold replacement time from about 2 hours to 30 minutes to about 1 hour and 30 minutes. In this case, it is possible to improve the production amount of about 100 per minute and therefore 6000 bolts, Safety incidents can be prevented, and the efficiency of the mold replacement work can be improved.
