Technical Field
[0001] The invention is related to punching machines which creates punching and forming
the sheet metals in different geometric shapes.
[0002] 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.
Prior Art
[0003] 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.
[0004] 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.
[0005] The following points regarding the punch machines used in the prior art negatively
affect the manufacturers;
- Processing only the leveled sheet metals ,
- Inability of providing structures that will produce complex products,
- Experiencing 25-40% loss of scrap when utilizing the sheet metal,
- Sheet loading time, e.g. experiencing time loss of 30 seconds to 2 minutes between
each operation.
[0006] In the patent search with respect to the existing technology , an application No.
TR 2011/12276 is encountered. In the abstract of this application, the following is disclosed:
The invention relates to a punch machine which comprises a circular lower turret where
the sheet metal brought to the production area to perform cutting and/or forming processes
thereon is fixed; a circular upper turret which extends parallel to said lower turret
in a manner to remain a certain space therebetween and will process on the sheet metal;
at least one fixed index assembly having multiple cylindrical assembly bearings formed
inside said upper turret and an assembly tip which is capable of being adapted into
said assembly bearings when required and will process on the sheet metal. Said punch
machine is characterized in further comprising at least one multi-index assembly having
an assembly bushing which is fixed into the assembly bearings to perform cutting and/or
forming processes on the sheet metal in desired shapes.
[0007] In another application No.
TR 2011/12281, on the other hand, the following is disclosed: The invention relates to a punch
machine which comprises a lower turret parallel to the ground surface and an upper
turret having an index assembly which comprises thereon an assembly body fixed thereto
with a temporary connection to form the sheet metal and an assembly bearing where
said index assembly is fitted, between which the sheet metal is positioned. Said punch
machine is characterized in that said assembly bearing is provided in a size suitable
to the assembly body with the largest diameter and that it comprises at least one
index group which is provided in such sizes to be adapted into all present assembly
bodies by being fixed to the assembly bearing when desired.
Description of the Invention
[0008] 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.
[0009] 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.
[0010] 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.
[0011] 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.
[0012] 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.
[0013] 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.
[0014] With the punch machine according to the invention;
▪ Complex products are processed,
▪ Low operating costs are provided,
▪ Quite long pieces can be processed, length limitation is eliminated,
▪ Ease of use is achieved compared to the other machines,
▪ Saving on labor is achieved,
▪ Ease of stocking is achieved as the system makes use of the roll,

▪ CNC punch machine operate automatically and there is no need to an operator continuously,
▪ Innovations such as the decoilers , straighteners and punching systems, and plate
CNC to be used as additional equipment are provided.
[0015] 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;
- at least two movable units moved linearly in y-axis in two separate working areas
when said coiled sheet metal is still in the form of roll prior to being cut;
- linear and circular motion group moving in x, y and z axis and configured on each
said movable unit;
- conveyor pushing the coiled sheet metal, the punching process of which is completed
by means of said hammer group and cutting punches, to the product exit;
