Description

Continuous milling system simultaneously treating both the top and bottom side of standard metal plate}

The present invention relates to a double-sided continuous machining apparatus for the production of standard metal plates for machining for parts of other systems.

In the processing and production of various parts using metal materials, devices for processing rectangular metal plate materials for metal processing component materials in the form of rectangular parallelepipeds have been used.

As shown in Fig. 1, the apparatus places the steel plate 1 on the conveying part 2, and then moves the conveying part 2 horizontally in a state in which the conveying part 2 is fixed by magnetic force and at the same time, the upper milling cutter. Rotate (4) to cut the plane of the steel sheet. Then flip the other side and repeat the same action.

This work requires low weight due to the operation of the metal plate, which has a heavy weight, and the inversion of the worker, which is low in productivity.

In order to overcome this disadvantage, as shown in FIG. 2 (Priority Registration No. 296088), the motor unit 6, a conveyor belt 7 having a magnetic force rotating by receiving rotational force from the motor unit 6, and the conveyor A device composed of a milling cutter (5) installed above the belt (7) was developed. The surface of the surface is cut with a milling cutter while the metal sheet to be processed loaded on the conveyor belt 7 is transferred.

Although the cutting operation of one side is easy by this apparatus, the inconvenience of repeating the machining operation by inverting the plate again for the lower cutting still remains.

In Patent No. 10-894847, which improves these disadvantages, as shown in FIG. 3, the input part 400 for supplying the metal plate material 1 to be processed and the top and bottom surfaces of the metal plate material 1 to be introduced are respectively planarized. The upper surface processing machine 200 and the lower surface processing machine 100 for cutting and processing, the transfer part 300 for moving the metal plate material 1 between the upper surface processing machine 200 and the lower surface processing machine 100, and the processed metal plate material 1 It provides a double-sided continuous processing plant consisting of a discharge part 500 is discharged.

The metal plate 1 to be processed is introduced into the upper surface processing machine 200 from the input unit 400, and the metal plate 1 processed by the upper surface processing machine 200 passes through the transfer unit 300, and then the lower surface processing machine 100. The metal plate 1 processed in the lower surface processing machine 100 is finally discharged to the discharge unit 500. The processing machines 100 and 200 are provided with a strong magnetic body inside the conveyor so as not to be shaken by the cutting cutter.

The above configuration allows the worker to process both sides without the need to turn the plate upside down, but the conveyor belt for transporting the metal plate to be processed is made of synthetic resin or rubber rather than metal. The reason is that the conveyor belt is fixed by the magnetic force applied for the transport when manufacturing the metal material. That is, since the conveyance function as a conveyor belt is lost, a belt made of a synthetic resin or a composite of rubber and synthetic resin that is not affected by magnetic force is used. These materials have to be compressed by the conveyor belt of rubber or synthetic resin while the metal sheet is fixed by the strong magnetic force. This compression causes a serious processing deviation in the precision processing of only 0.1 to 1mm or less surface processing.

Another problem is that the conveyor belt is rotated while pulling the drive pulley and the driven pulley on both sides, the operation of the unavoidable conveyor belt is generated due to this operation. As a result of repeated use, as well as deformation of tension due to temperature differences in winter and winter seasons, there are always uneven transport and height variations due to changes in tension. Such deformation causes a difference in the distance between the metal sheet material to be processed and the distance between the feed surface and the cutting cutter.

The present invention is to provide a device capable of continuous processing the upper and lower surfaces of the rectangular metal sheet.

It is an object of the present invention to provide a processing apparatus, in particular, which is provided with a feeder that can maintain a constant contact distance between the cutting cutter and the surface of the metal to be processed.

The present invention has developed a feeder that does not have a height or position variation during transfer of the metal sheet in cutting the metal sheet with a cutting device.

In particular, the present invention provides a method of accurately correcting a metal plate to be processed by using a transfer device that essentially excludes a transfer device that may cause height or position shift between the magnetic suction device for fixing and the metal plate. In addition to the feed, the processing deviation due to the height change during processing is minimized.

The present invention continuously processes the upper and lower surfaces while the primary processing portion and the secondary processing portion are continuously connected in claim 1. In particular, the metal plate to be processed is directly fixed to the primary and secondary feeders while being directly transported, thereby fundamentally blocking processing errors that may occur.

In Claims 2 and 3 of the present invention, as soon as the primary processing is completed, the metal plate is lifted to the upper part and fixed directly to the secondary feeder of the secondary processing unit. Therefore, the first and second processing can be done simultaneously to increase the processing speed and greatly increase the productivity.

Claim 4 of the present invention can continuously process the lower surface of the metal plate material processing the upper surface in the primary processing portion.

In particular, the present invention relates to a processing apparatus for continuously producing a workpiece having a precision for use as a material for other secondary processed products by smoothly processing a surface of a metal plate member having a rectangular wide plate structure.

The present invention is to provide a processing apparatus capable of processing the upper surface precisely by continuously inputting the heavy-weight feeder plate material, and can continuously process the lower surface.

The present invention can provide a processing apparatus capable of precisely processing within a processing error in which the surface of the processed metal sheet is set during the surface cutting treatment in fixing and transferring the metal sheet to be processed.

The present invention is to process the lower surface while transporting the metal plate of the rectangular structure to the processing unit, the primary processing unit for processing the upper surface of the metal plate to be transferred, the lower surface of the metal plate treated by the primary processing unit exposed to In the double-sided continuous processing apparatus of a metal sheet composed of a secondary processing portion to be processed,

The primary processing unit (A) which loads and transfers the metal plate material (W) to the primary transfer device incorporating a lifting device, and processes the primary cutting device in contact with the upper surface of the metal plate material to be transported.

The metal plate processed by the above primary processing unit is lifted by the lifting device of the primary feeder, and is fixed to the secondary feeder so that the lower surface is exposed. The secondary cutting device is in contact with the exposed lower surface. It relates to a double-sided continuous processing apparatus of a metal sheet including a secondary processing portion (B).

In the present invention, the primary feeder of the primary processing unit is provided with a guide rail (r) from the input unit 100 to the secondary input unit 200, the guider (g) to move forward and backward while sliding along the guide rail. do. The guider is engaged with the forward / backward actuator a, and the forward / backward movement of the guider and the body part connected with the forward / backward actuator are driven by the driving force of the driving unit 15. When the body portion 11 of the primary processing portion advances along the guide rail, the upper surface of the metal plate W is processed by the primary cutting device C1.

In the present invention, the primary transfer device of the primary processing portion has formed the access grooves 12 in the body portion 11 that can transfer the metal plate material. The entrance groove is constructed so that the metal plate to be processed on the upper surface can be vertically lifted as the lifter of the lifting device moves in and out, and the magnets can be fixed inside the body by embedding magnets that can be excited. It was constructed.

As shown in the drawing, a strong magnetic force can be arbitrarily turned on and off inside the primary feeder. Once the metal sheet to be processed is in contact with the surface, it is fixed so that it cannot be moved in any of up, down, left, and right directions. The conventional conveying apparatus is configured to gradually convey the metal sheet material toward the cutting surface of the machined part even if it is fixed. This configuration inevitably generates some vertical or horizontal vibrations during the transfer because the transfer is made while overcoming the strong magnetic force of the fixing device. These vibrations and positional deformations are insignificantly small, but in the case of precision processing of less than 0.1mm, these minor positional shifts fundamentally prevented the machining error from occurring on the surface.

And the lower part of the body portion of the primary transfer device is configured to enable the forward and backward as a whole by the drive unit 15 to the body portion and the pneumatic cylinder 17 for lifting up and down. The installation in the lower part mainly installs a linear motion guide such as LM guide, and makes it move forward and backward by the rotational force of the screw in forward and backward motion of the pneumatic cylinder or driving force such as motor.

In the present invention, the primary processing unit having the above-described configuration, the specific operation and structure of the lifting device for lifting the processed metal plate after the primary processing is installed as shown in Figures 5, 7, 8.

The surface of the primary feeder is machined precisely so that the metal sheet can be closely adhered to, and it is always removed by blower immediately after the end of the primary processing so that chips generated during metal sheet processing do not remain. There was no irregularities on the surface. And the lifter entering and exiting the access groove is composed of a vertical bar (13b) for fastening with the horizontal bar (13a) and the working rod 17 of the hydraulic cylinder was configured to vertically lift or lower the metal plate to be processed by the horizontal bar.

The lifter is a surface processing of the workpiece from the input unit 100 to the secondary input unit 200 in the state of being embedded in the access groove of the body portion. When the primary surface processing is completed, the body part reaches the secondary input part 200 of the secondary processing part, and when the second input part detects that the second input part is detected by a separate sensor, the lifter is shown in FIGS. 6 and 9. And it rises vertically as shown in FIG.

The secondary feeder of the secondary processing part also has a guide rail (r-1) installed in the form opposite to the primary feeder from the secondary feed part 200 to the discharge part 50, while sliding along the guide rail. Install the guider (g-1) moving forward and backward. The guider is engaged with the forward / backward actuator a-1, and the forward / backward movement of the guider and the body part connected with the forward / backward actuator are driven by the driving force of the drive unit 15-1. Therefore, since the body portion 31 of the secondary processing portion is disposed toward the ground along the guide rail, when the metal sheet W advances here while being fixed to the magnetic force, the metal sheet W is applied to the secondary cutting device C2. The lower surface of the was configured for processing.

Reaching the secondary input portion 200, the metal plate member which is raised and loaded upward by the operation rod 17 is lifted on the surface of the body portion 31 of the secondary processing portion, built in the body portion 31 Adsorbed by magnetic force.

When the metal sheet is fixed to the body portion of the secondary processing portion, the metal sheet is held in the air in the unprocessed metal sheet, and the lower portion of the metal sheet is exposed and the lower portion of the secondary cutting device C2 is transported by the secondary feeder. Processing takes place.

In the present invention, the secondary transfer device of the secondary processing unit is configured to enable the magnetic force fixing of the metal plate by embedding magnets magnetizable in the inner side of the secondary body portion 31 capable of loading and transferring the metal plate,

The lower part of the secondary body portion is configured to enable the forward and backward as a whole by the drive unit 35,

When the body part reaches the discharge part 50 of the secondary transfer device, the discharge load part 52 which is lifted and lowered by the pneumatic cylinder installed in the processed product loading part 51 of the discharge part is raised to raise the secondary body part of the secondary feed device. The machined metal plate which is lowered by the magnetic removal was configured to be loaded.

As another feature of the present invention, as shown in Figs. 11 to 14, the primary air capable of removing foreign substances by discharging high-pressure air toward the upper surface of the body portion 11 for loading the metal plate of the primary processing portion. The blower 16a is installed. The primary air blower has a width that can cover the whole body part, and blows high-pressure air while advancing the body part back and forth by a separate hydraulic cylinder.

In addition, a hemispherical secondary air blower 16b is installed close to the outside of the primary cutting device C1 of the primary processing portion, and the cutting chip is blown with high pressure air. In addition, a rotary brush 16c is installed between the primary cutting device and the secondary processing part so as to contact the metal plate W, and the chips remaining on the metal plate even after the blowing process are directly removed by a brush. In addition, a secondary air blower 16d for blowing high-pressure air toward the side of the secondary body portion 31 of the secondary processing portion is further installed to remove the cutting chip. In the secondary processing part, since the lower part of the metal plate is exposed, most chips fall by their own weight after the cutting process with the primary cutting device, and the remaining ones are removed by high pressure air.

Another feature of the present invention is a device for processing the lower portion of the metal plate in the secondary processing unit and then loading the metal plate without surface damage. More specifically, as shown in FIGS. 15, 16, and 17, rollers 56 connected to the chain 54 that are continuously rotated by the driving motor 55 are arranged to be movable in a predetermined direction when the metal sheet is loaded. Configure. And between these rollers, the workpiece loading part 51 which raises and lowers by the hydraulic cylinder was provided. When the transfer of the metal sheet in the secondary processing portion reaches the discharge unit 50, the advance of the secondary body portion 31 of the secondary processing portion is stopped. When the forwarding of the secondary body portion is stopped, the workpiece load portion of the discharge portion is raised to contact the lower portion of the metal plate material after the secondary processing is completed to prevent the lowering, and then the power supply to the magnet embedded in the secondary body portion is prevented. The magnetic force is lost by the off and the metal sheet is lowered due to its own weight. The metal sheet material is loaded into the workpiece load portion and descends to the lower portion, and is loaded on the roller 56 of the discharge portion and transported. When the transfer reaches the end of the discharge part, it is detected by the drop prevention sensor 57 installed here, and further stops the forward movement, and then transfers the metal sheet to another side processing part by a separate transfer device, not shown. Process with This configuration allows the surface to be precisely processed and prevents damage to the surface due to collisions between products during random discharge. In addition, it is possible to fully automate the processing of the product, and the information of the product collected by the drop prevention sensor is made into a database by a separate computer (not shown) to enable automated management of the entire factory.
