The punch machine (1) which performs punching in the materials in the form of coiled sheet metal (200) by means of the punching tool (118) and hammer group (117) and pressing ram (115) producing motion in vertical z-axis, characterized in comprising at least two movable units (114) moved linearly in y-axis in two separate working areas when said coiled sheet metal (200) is still in the form of roll prior to being cut; groups configured on each said movable unit (114) and moving in x, y and z axis; a conveyor (125) pushing the sheet metal coil (200), the punching process of which is completed by means of said pressing ram (117) and punching tool (118), to the product exit (A1); and guillotine shears (124) cutting the coiled sheet metal (200) advanced to the final section by means of said conveyor (125) in determined sizes.
The invention is related to punching machines which creates punching and forming the sheet metals in different geometric shapes.
Said invention is related to a punching machine, which the coiled sheet material is uncoiled , straightened and moved forward and reverse in the determined dimension , and then subject to punching, forming and notching processes in the coiled sheet metal punching machine, and the sheet metal is delivered through conveyor without any help of operator support.
In the punching machines used in the prior art, tool is fixed and sheet metal is movable or the tool is movable and sheet material is fixed. In both cases, punching process is performed on the sheet metal in different geometric shapes by means of the cutting tool.
In the existing system , sheet metal is cut in the required sizes by the cut-to-length line, then is stacked in the form of plate and packed. Afterwards, plate materials, which are stacked up, are taken one by one by means of one or two operator(s) and placed on the working plane of the punching machine. In fact, this situation results in high labor force and production process. First cutting of the sheet metal in desired size, arranging and then positioning the same on the bench by operators substantially affect the production process and costs. Besides, as sheet metal is utilized it is obligatory to adhere to size dimensions of the sheet metal. Likewise, as sheet metal is utilized, due to the limitations again in the sizes, difficulties are experienced during placement and large amount of scrap is produced while the product to be released is being programmed.
The following points regarding the punch machines used in the prior art negatively affect the manufacturers;
In the patent search with respect to the existing technology , an application No.
In another application No.
The object of the invention is to process the sheet metal in the form of coil instead of the sheet metal processed one by one in the form of plate in the prior art. Thereby, processing of the sheet metal rapidly and with low cost without requiring extra time and labor is performed.
One object of the invention is to perform the production by processing the sheet metal rapidly and with low cost, to substantially save on energy and to present a punch machine with a 3-axis freedom.
Another object of the invention is that two movable tool holder units will perform the lateral motions while unidirectional motion thereof forms the sheet metal. While the tool holder units perform the unidirectional motion, thanks to the fact that the two tool holder units are capable of moving independently of each other, they are provided with the ability of processing simultaneously but differently on the sheet metal to be processed.
Another object of the invention is to save on the sheet metal as it is in the form of coil and then again to cut the sheet metal by means of guillotine shears integrated to the punch machine. The sheet metal, which is cut, is removed from the cutting line by a conveyor means without requiring any operator.
Another object of the invention is that the 3-axis CNC punch machine has the features to provide processing of the sheet metal coil. All the processes of the product to be produced by computer numerical control are performed in line with the program to be preinstalled in the machine with semi skilled labour.
Another object of the invention is to provide transition from the technical drawing of the product directly to the operation of the machine by a single operator by means of a special software. Thus, the use of a single operator is ensured in the machine and stacking is performed automatically.
With the punch machine according to the invention;
To achieve the aforementioned objects, the invention is a punch machine which performs punching in the sheet materials in the form of coiled sheet metal by means of the cutting tool and hammer group and pressing ram producing motion in vertical z-axis, characterized in comprising a front inlet panel with a product inlet opening through which said coiled sheet metal is entered;
The punching machine (100) performs punching the sheet materials in the form coiled sheet metal (200) by means of the punching tool (118) and hammer group (117) and pressing ram (115) which moves in vertical z-axis. It comprises a front inlet panel (110) with a product entry opening (126) which the coiled sheet metal (200) is entered. It comprises at least two movable units (114) moved linearly in y-axis in two separate working areas when said coiled sheet metal (200) is still in the form of roll prior to being cut; and a structure moving in x, y and z axis and configured on each said movable unit (114). Moreover, it comprises a conveyor (125) pushing the coiled sheet metal (200), the punching process of which is completed by means of said hammer group (117) and cutting tool (118), to the product outlet (A1); and guillotine shears (124) cutting the coiled sheet metal (200) advanced to the final section by means of said conveyor (125) in determined sizes. Likewise, the motion of the double movable unit (114), which are moved linearly in two separate working areas, in y-axis is provided by means of the drive mechanisms.
Figure-1 is the representative front general perspective view of the punch machine (100) according to the invention when the sheet metal (200) in the form of coil is subjected to the process. The coiled sheet metal (200) is driven through the product entry opening (126) formed in the front inlet panel (110) from product entry (A) section into the machine. In accordance with the parameters determined by the CNC system, the coiled sheet metal (200) driven into the machine is punched by means of the hammer group (117) and punching tool (118) illustrated in Figure-2. There are connectors (120) connecting the machine to the ground and carrying all the load.
In Figure-2, the front inlet panel (110) is removed for a clearer understanding of the system. Punching process is applied to the sheet material by means of the hammer group (117) and cutting tool (118). The punch machine (100) comprises double movable unit (114). Symmetrical movable units (114) are linearly moved in y-axis by means of the cassette (119). Linear motion in y-axis is provided by drive mechanisms. Linear motion of the cassette (119) is provided. Each movable unit (114) is capable of moving linearly and circularly. The movable units (114) operate in two different areas, thereby performing the punching process rapidly in a shorter time. With the z-axis motion of the hammer group (117), motion is provided in vertical axis. Vertical motion of the hammer group (117) in z-axis is provided by means of the pressing ram (115).
Figure-3 is the representative top two dimensional view of the punch machine (100) according to the invention. After the punching processes applied to the coiled sheet metal (200) from two sections or two different areas by means of the movable units (114), the punching process is completed. Then, the coiled sheet metal (200) conveyed to the final section is pushed toward the product exit (A1) by a conveyor (125) integrated to the punch machine (100). The coiled sheet metal (200) pushed by the conveyor (125) is cut by means of the guillotine shears (124) and the end product is obtained.
The punch machine (100) with CNC system has features which will provide processing of the coiled sheet metal (200). All the processes of the sheet metal part to be produced by computer numerical control are ensured to be performed in line with the program to be pre installed in the machine with less workmanship. Thus, a machine with mass production and low cost is presented. Thanks to the CNC feature thereof, the machine can operate integrated with decoiling , straightening, feeding and punching system equipments.
