Description

{Apparatus for guiding of meterial}

The present invention relates to a material guiding apparatus, and more particularly, to a material guiding apparatus for preventing the rear side of a workpiece from being lifted.

Generally, the wire material is heated in a heating furnace (H) at 950 to 1150 degrees so that the sheet material can be hot rolled at 160 * 160 m / m in a cross section. As shown in Fig. 1, Cross-continuous rolling in round and oval-shaped caliber through horizontal and vertical rolling mills of rolling and intermediate rough rolling, followed by gradual reduction of hot cross section in the process of forming rolling, Can be obtained.

As a result, the front end and the rear end of the material are partially cut off by a crop blade, and the front end portion and the rear end portion of the material are partially cut off by a crop blade, When a cobble, which is a defective product, is generated in the material being rolled due to a trouble, the material is chopped by a chopping blade to be cut off. At this time, cutting the entire material is called cobble scrap.

Here, the prior art rotary cutter 2 related to the present invention can be disposed in the rough rolling process in order to cut a material having a relatively large cross-section and a slow rolling speed. For reference, the other rotary cutter 2 'is disposed before the finishing rolling process to cut a material having a relatively small diameter and a relatively high speed, so that only the cutting edge portion of the material is cut.

For reference, the material subjected to finish rolling after this process is temperature-controlled by WB (facility for cooling with water), and then the winding equipment of the laying head 3 is formed into a wire coil of a circle shape. At this time, the material having a large diameter before the finishing rolling is integrated with the roll 1 'in the reel 4, transferred to another conveyor, and is heat-treated and finished with the product.

2 is a side view showing the operation of the rotary cutter in the wire rolling apparatus of FIG.

Referring to the drawings, the rotary cutter 10 is configured such that two rotating bodies 11a and 11b having a plurality of blades 12 are rotated, and a material 1 is sandwiched between the two rotating bodies 11a and 11b The material 1 is cut when the two rotors 11a and 11b are rotated and the material 1 is inserted between the two blades 12. [

Fig. 3 is a front view of the rotary cutter of Fig. 1 viewed from the front; Fig.

2 and 3, the crop blade 12a of the rotary cutter 10 is attached to the upper rotating body 11a and the lower rotating body 11b one by one so that the rotating bodies 11a and 11b rotate in one rotation One blade engagement will occur.

The chopping blade 12b is provided with two blades attached to the upper and lower rotors 11a and 11b in parallel with the crop blade 12a so that when the rotors 11a and 11b make one revolution, Blade engagement occurs so that the material (1) is chopped.

That is, the crop blade 12a is generally used to cut only the front end and the rear end of the work 1 when the work 1 is normally rolled. When chopping of the work 1 is required due to a failure in the production line The long material 1 is cut once so that the work 1 can be moved to the chopping line.

3 (b) is a side view showing that the material is cut by the crop blade and the chopping blade. In this case, the upper blade is inserted and cut in the material while the material is supported by the lower blade, The cutting is performed below the horizontal center line of the cutter.

4 is a perspective view showing a work guide apparatus and a peripheral structure according to the prior art in the wire rolling apparatus of FIG.

Referring to the drawings, when the rotary cutter 10 cuts the leading end portion of the work 1, the work 1 starts to move at the timing of passing the rolling mill 18, and passes through the pipe type exit guide 19 (Deflector) 14 placed in the following date format.

At this time, the material 1 is placed at the engaging position of the rotary cutter 10 and then cut by the driving force for discharging the work 1 in the rolling mill 18, and the cut crop blade 12a is rotated and re- .

Thereafter, the cut material 1 passes through the rotary cutter 10 without intervention of the blades 12, the entrance is wide and the exit is directed to the narrow rectangular panel guide 23 and then guided to the next mill.

On the other hand, the material guide device 14 is provided with a cylinder 15. A pin 17 serving as a rotary shaft for rotation of the workpiece guiding device 14 is disposed on the entrance side, and guide grooves 16a And a protrusion inserted into the guide groove 16a and moving along the guide groove 16a.

When a chopping operation of the work 1 is required, when a signal is inputted by the driver, a delay time is given so that the work 1 passing through the rotary cutter 10 is first cut by the crop blade 12a, When the cylinder 15 pushes the workpiece guiding device 14 so that the workpiece 14 can be shifted in the chopping line direction, the workpiece guiding device 14 rotates about the pin 17. At this time, the projections formed in the lower part of the work guide device 14 are guided in the guide grooves 16a formed in the rail base 16, so that the rotation direction of the work guide device 14 is guided.

The material guide device 14 rotated about the pin 17 serving as a rotary shaft guides the moving workpiece 1 to the position where the chopping blade 12b is engaged and the chopping blade 15b is moved The entire amount of the generated material (1) is finely cut and processed.

FIG. 5 is a diagram showing a line failure occurring due to lifting of a workpiece in a chopping cutting line in the workpiece guide of FIG. 4;

Referring to the drawings, in the process of chopping and cutting the preceding material (1a) with the quality trouble of the rolling and back-end equipment (winding, cooling equipment, etc.), there is no driving force, The upper blade is inserted deeply into the material and cut at a position below the horizontal center line of the material in a state in which the lower blade supports the material as shown in Fig. 3 (b) As a result, the rear portion of the preceding material 1a is lifted at the time of cutting.

At this time, the trailing material 1b successively extracted at intervals of 5 to 6 sec intervals enters the space where the trailing material 1a is held, so that the blade cuts the leading material 1a and the trailing material 1b together There is a problem that a breakage of the blade is broken and an excessive downtime occurs due to the replacement of the blade irregularity.

Further, when the ongoing material pushes the blade surface when the rotary cutter 10 is stopped due to recovery delay and trip in tripping due to the motor overload transmission of the rotary cutter 10, the blade fixing portion (assembly hole: weak portion) Equipment accidents that are lost due to breakage, and short and long cuts or poorly swinging cuttings and intermittently not chopped materials can cause problems of large accidental accidents involving the installation of rotary cutter 10.

On the other hand, the rear material 1b enters into the floating space of the preceding material 1a in a time of shorting while the rear side of the preceding material 1a is heard, causing a worse condition in the preceding material 1a, 1b) has a problem in that it is necessary to perform maintenance by dropping or destroying the exit guide 19 due to occurrence of a loop that is a shape deformation due to a progressive resistance failure due to a career obstruction and a collision, .

The present invention relates to a cutting machine for cutting a work 1 with a guide body 100 for guiding the work 1 to a cutting or chopping cutting line and a cutting machine (200) provided to the main body so as to block the main body (200).

The guide body 100 includes a guide receiving portion 110 for guiding and guiding the work 1 to be passed therethrough, a cylinder for rotating the guide receiving portion 110, A pin, and a rail base for rotationally guiding the guide receiving portion 110. The guide body 100 may be constructed so as to guide the material 1 in the direction of turning to a cropping or chopping cutting line, but the specific structure is not limited.

Here, the injury preventive means 200 may include an injury preventing portion configured to urge the work 1 to be lifted when the work 1 is cut downward.

In the rotary cutter disposed at the rear end of the workpiece guiding device, the upper blade is pressed against the work 1 in a state in which the work 1 is supported by the lower blade as shown in Fig. 3 (b) The cutting is performed below the horizontal center line of the work 1, so that a rear side portion of the work 1 is lifted at the time of cutting. Particularly, when the chopping cutter is cut, the rear portion of the material 1 is greatly lifted.

In order to prevent this, the above-mentioned injury-preventing portion plays a role of downwardly pressing the work 1, thereby preventing the rear portion of the work 1 from being floated.

At this time, the injury preventing unit may be provided with a pressing roller 220 for rolling down the material 1 while rolling it downward.

Preferably, the flotage prevention portion may be provided with a plurality of pressing rollers 220 so that the entire portion of the material 1 can be downwardly pressed.

The plurality of pressing rollers 220 may have a downwardly inclined arrangement structure in the direction of advance of the work 1. That is, the height of the pressing roller 220 may be relatively increased toward the rear side so that the advancing material 1 can smoothly enter the lower side of the pressing roller 220. At this time, a plurality of the pushing rollers 220 may be fastened to the support frame 210 to be connected to each other.

The pressing roller 220 may be composed of an idle roll 221, a bearing 222 and a supporting shaft 223 which rotate in a non-rotating manner. The supporting frame 210 is supported by a supporting shaft 223 may be inserted and fastened to the assembly groove 210a.

At this time, the supporting shaft 223 of the pressing roller 220 may have a rectangular cross-sectional structure so as to be firmly fixed without being rotated after being inserted into the fitting groove 210a. After the support shaft 223 is inserted into the assembly groove 210a, the fixing bracket 228 is mounted on the support frame 210 with the fastening member such as a bolt to be disposed on the upper portion of the assembly groove 210a, It is possible to prevent the support shaft 223 from deviating from the groove 210a.

The clamping groove 111 may be formed in the guide body 100 so that the pushing roller 220 may be inserted into the guide body 100 to limit upward movement of the pushing roller 220. In this case, And can be prevented from being pushed upward by the rise of the rear portion of the work 1 after being fastened to the groove 111.

Specifically, the coupling groove 111 may be formed with a blocking portion 111a that is inclined downward, bent, or bent to block the lifting of the pressing roller 220. That is, the pushing roller 220 is pulled into the clamping groove 111 and fastened by the pushing roller 220. When the pushing roller 220 is fastened, the support shaft 223 is downwardly moved by its own weight so as to extend downward At this time, the blocking portion 111a may be formed such that the blocking portion 111a may be inclined and bent or bent to restrict the upward movement. In the drawing, an oblique structure is shown, wherein the blocking portion 111a corresponds to a lower end portion. In particular, since the support shaft 223 has a rectangular shape, it can not be easily moved vertically upward due to friction in the inclined engagement groove 111.

The flotage preventing means 200 supports the support frame 210 on which the plurality of pressing rollers 220 are mounted while releasing support of the support frame 210 during chopping and cutting, And may further include a support member 230 for dropping.

That is, the support member 230 may be fixed to the support frame 210 on which the pushing roller 220 is mounted so that the pushing roller 220 can be installed on the guide body 100 only when the work 1 is on the chopping cutting line When the guide receiving portion 110 is rotated and turned to the chopping cutting line at this time, the holding support of the supporting frame 210 is released so that the pressing roller 220 is fastened to the guide receiving portion 110 So that it can be dropped into the groove (111).

Specifically, the support frame 210 is formed with a retaining ring 211 to be retained by the retaining member 230, and the retaining member 230 is inserted into the retaining ring 211 to retain the retaining ring 211 And may be disposed on one side of the guide body 100 so that the hook body 211 may be detached when the guide body 100 is turned to the chopping cutting line.
