Description

[0001] DESCRIPTION [0002] Punching apparatus of profile [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a punching apparatus for a profile, and more particularly, to a punching apparatus for punching a sidewall of a pultruded profile with excellent workability,

Generally, in the case of constructing a structure by using a profile that is drawn by an aluminum material, a joining hole, a joining portion, or the like is machined to the side of the profile for assembly of the profile.

That is, after the joining portion is formed by punching the side surface of the profile that is pull-drawn in various forms such as "L" type, "C" type, "LL" type and " And cut to length.

The conventional profile punching and notching processes include a process of drawing a profile in a draw-forming machine, a process of cutting the drawn-out profile to an appropriate length in a cutter, a process of punching the cut profile in a punching machine, Since the process is carried out by a plurality of devices, a large number of manufacturing facilities and a large number of workers are required, and workability and productivity are greatly reduced.

Particularly, in the conventional punching machine of the punching process, the punch is punched on the sidewall of the profile while lowering the punch from the upper portion of the die to the operating cylinder. Since the punch has no structure for guiding or separately supporting the profile to the machining position, Of course, the efficiency is low, and the pressing impact of the punch can not be buffered separately, so that the quality of the punching hole formed in the sidewall of the profile is not smooth and the quality of the work is poor.

Patent Registration No. 10-1551428. Patent Registration No. 10-1177563.

The present invention has been made to solve all the problems of the prior art described above, and it is an object of the present invention to provide an excellent punching process of sidewalls of a draw-formed profile, thereby providing excellent workability and efficiency as well as product quality.

According to the present invention, there is provided a punch block comprising: a fixed base block fixedly mounted on a frame; a punch block coupled to the fixed base block; a slit groove in which a sidewall of the profile is inserted and guided into the punch block; And a punch which is inserted into the punch hole and is pushed by the punch cylinder to punch the joint hole into the side wall of the profile.

According to the present invention, an assembling groove having a notch cut out laterally is formed in the engaging hole so as to be axially assembled by inserting the head of the punch laterally from the side of the punch, It is characterized by its construction.

The punch block is coupled to the fixed base block by a rail so as to be movable forward and backward in a punch pressing direction. The tip end of a spring shaft inserted into a spring block coupled to the fixed base block is screwed to the punch block, A buffer spring is inserted into both sides of the spring block so that the punch block is buffered and moved back and forth.

According to the present invention, a punch block coupled to a lower portion of a fixed base block opposes a slit groove into which a side wall of a profile is inserted and guided, and a punch hole and a die hole into which punches are inserted on both sides of the slit groove, The punching hole is punched in the sidewall of the profile while being pressurized, so that it has an excellent effect on workability and efficiency as well as on the product quality.

Particularly, since the punch block is buffered before and after the punch pressing operation in the fixed base block, the punching operation shock is buffered as well as the punching impact is applied to the side wall of the profile.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 4, the punching device of the present invention includes a fixed base block 10 fixed to a frame, a punch block 20 coupled to the fixed base block, and a profile 2 (22) and a die hole (23) formed opposite to both sides of the slit groove (21), and a die hole (23) inserted into the punch hole (22) And a punch 30 for punching the engaging hole 3a in the side wall 3 of the profile while being pressed by the punch cylinder 40. [

At this time, the guide bushing 34 is inserted into the punch hole 22 to guide the movement of the punch 30. As shown in FIG.

The punch cylinder 40 is provided with a coupling hole 42 coupled to the rod 41 and a head 32 of the punch 30 so as to be axially coupled to the coupling hole 42, 46 are formed and the head 32 of the punch is laterally inserted.

The punch block 20 is coupled to the fixed base block 10 in such a manner that the punch block 20 can be moved forward and backward in the punch pressing direction by the rails 11 and inserted into the spring block 12 coupled to the fixed base block 10, And the cushion springs 17 and 18 are inserted into both sides of the spring block 12 to the punch block 20 so that the punch block 20 ) To move back and forth.

The profile 2 is formed by drawing an aluminum material into various shapes such as "L" shape, "C" shape, "LL" shape and "ㅛ" shape as shown in FIGS. will be.

Reference numeral 19 denotes a washer, reference numeral 50 denotes a die cover, and reference numeral 60 denotes a guide bracket coupled to the tip of the punch.

Hereinafter, the operation and operation of the present invention will be described.

First, the present invention is characterized in that, in the assembling process, the head 32 of the punch 30 is inserted into the mounting groove 45 having the notch 46 at the side of the fitting hole 42 to be coupled to the rod 41 of the punch cylinder 40 So that the shaft assembly is simply assembled.

When punching the profile 2 with the apparatus of the present invention, the side wall 3 of the profile 2 is automatically inserted into the slot groove 21 of the punch block 20 manually or by a feeding means Supply.

At this time, a portion to be punched on the sidewall 3 of the profile is positioned between the punch hole 22 and the die hole 23 in the slot groove 21.

In this state, the punch 30 connected to the rod and the coupling hole 42 is actuated by the extension of the rod 41 of the punch cylinder 40.

The tip end of the punch 30 is punched by pressing the side wall 3 of the profile 2 inserted into the slot groove 21 of the punch block 20 by the pressing operation of the punch 30. [

The punching operation causes the engaging hole 3a to be punched in the side wall 3 of the profile 2 and the scrap separated from the engaging hole is discharged through the die hole 23. [

Particularly, in the punching operation of the punch 30, the punch block 20 moves back and forth in the punch pressing direction along the rail 11 from the fixed base block 10.

At this time, a cushion spring 17 (see FIG. 1) is provided on both sides of the spring block 12 on a spring shaft 15 inserted into the spring block 12 coupled to the fixed base block 10 and having a tip end screwed to the punch block 20, ) 18 is inserted into the punch block 20 so that the punch block 20 performs buffer operation when moving back and forth.

That is, when the punch 30 is pressed or returned to its original position by the punch cylinder 40, the punch block 20 is urged by the cushion spring 17 18, the side wall 3 of the profile is punched in an adhered state, as well as a shock absorbing effect is absorbed during punching operation or returning operation, so that the engagement hole 3a formed in the side wall 3 of the profile ) Can be prevented and punching quality can be excellent.

Therefore, the present invention is to simply and effectively punch the sidewall of the drawn and formed profile, particularly to ensure excellent punching quality of the profile.
