Definitions
- the present invention relates to an apparatus for manufacturing window/door frames or bent metal products, and more particularly, to an apparatus for manufacturing window/door frames or bent metal products, in which the window/door frame or bent metal product manufacturing apparatus is configured to include upper and lower surface support rollers, left and right side support rollers and forming rollers as a forming roll set that forms window/door frames or bent metal products, to thus prevent a reaction force that the forming rollers influence upon a plate-shaped member during a process that the upper and lower surface support rollers and the left and right side support rollers support the plate-shaped or sheet member, and to thereby fundamentally block a wave phenomenon from occurring in the plate-shaped or sheet member that passes through the forming roll set.
- insulation windows/doors have an insulation function and a soundproof function, and are mainly used extensively for general houses, commercial houses, apartment houses, apartment building with stores, offices, etc.
- Aluminum or PVC is used as a material of the insulation windows or doors.
- the insulation windows or doors include a sash that is fixed on a wall and a window/door frame that is hinge-combined with the sash.
- a structural stainless steel plate-shaped or sheet member for producing the insulation windows/doors is standardized by 1 m wide and 3 m or 4 m long, and sold on the market.
- a window frame of a general commercial store in the first floor is 2.6 m-2.7 m high.
- a frame bending process includes: the steps of sequentially pressing a V-cut portion of a sheet member with a blade of a folding machine; making a required angle; sequentially turning and bending the sheet member upside down while replacing the blade of the folding machine depending upon a frame, to thereby complete the frame.
- a fraction defective and a product quality may be determined according to ability of an artisan.
- the window/door frame that is made using the conventional folding machine is weak in view of soundproof, wind resistance and dustproof, and especially is poor in view of insulation property, to thereby cause energy loss during air-conditioning.
- Mohair grooves exist in upper and lower H-type bars of a reinforced glass door, respectively, in order to realize soundproof, wind resistance, and dustproof, in which mohair is fitted into the mohair grooves.
- the H-type bars are stainless steel frames that are fitted in the upper and lower ends of the reinforced glass door to thus protect glass and to make a floor hinge lot attached and fixed to the stainless steel frames.
- paper weather strips or tapes are attached to the stainless steel frame and the reinforced glass door to block the gaps, to accordingly cause poor appearance and no practicality.
- the present applicant filed a Korean Patent Application No. 2006-85246 entitled a window/door frame manufacturing apparatus including a pinch roll set and a forming roll set that can make a plate-shaped member for the window/door frame move freely, on Sep. 5, 2006, and registered as a Korean Patent No. 0791647, to thus selectively apply a physical pressure to a bent portion of a product and to accordingly enhance an economical efficiency as well as provide a more convenient manufacturing process.
- the plate-shaped member that is formed using the above-described frame manufacturing apparatus are made to contact the upper and lower structure of the forming roll set, on a surface to surface basis, a physical force is not uniformly transferred to a portion of the plate-shaped member to be bent during bending. As a result, a wave phenomenon that the plate-shaped member becomes uneven has occurred.
- the conventional forming roll set is designed to make the plate-shaped member contact each other on a surface to surface basis using upper rollers and lower rollers, and to rotate to make the plate-shaped member transformed into an appropriate shape.
- a forming roll of a portion to be bent is configured into a conical shape, a first half portion and a second half portion of the forming roll set are made to rotate once at an identical time. Accordingly, there is a difference between a distance through which the first half of the forming roll set rotates and a distance through which the second half of the forming roll set rotates.
- the second half of a big diameter moves farther than the first half during a time that the first half of a small diameter rotates by a shorter distance than the second half, the physical force that is applied to the plate-shaped member is not identical in the first and second halves. As a result, the wave phenomenon occurs during bending the plate-shaped member.
- a forming roll set adopts upper and lower surface support rollers and left and right side support rollers at the upper and lower portions and the left and right sides of a plate-shaped or sheet member, to thus stably support the plate-shaped or sheet member and to then form window/door frames or bent metal products, and transfers a uniform physical force to the plate-shaped or sheet member, to thereby fundamentally block a wave phenomenon from occurring in the plate-shaped or sheet member that passes through the forming roll set.

- a number of groups of pinch roll sets 30 that are configured into active type upper and lower roller shapes that receive power transmitted from outside to thus compulsively transfer the plate-shaped or sheet member, and that are arranged in a straight line at regular intervals to thus enable the plate-shaped or sheet member to be continuously transferred in various forming operation sections;
- each of the forming roll sets 40 comprises;
- upper and lower support rollers 40 a and 40 b that are installed on the upper or lower surface of the plate-shaped or sheet member or the upper and lower surfaces thereof, and whose cylindrical outer circumferential surfaces closely contact the plate-shaped or sheet member, to thus support the upper or lower surface of the plate-shaped or sheet member or the upper and lower surfaces thereof that move through the pinch roll sets;
- folding rollers 42 a and 42 b that are installed on the inner or outer surface of the plate-shaped or sheet member, and whose cylindrical outer circumferential surfaces closely contact the inner or outer surfaces of the plate-shaped or sheet member, to thus apply a uniform pressure to the plate-shaped or sheet member to thereby form a three-dimensional plate-shaped or sheet member whose side surface is bent;
- left and right side surface support rollers 41 a and 41 b that are installed on the side surface of the plate-shaped or sheet member, and whose cylindrical outer circumferential surfaces closely contact the vertical surface of the plate-shaped or sheet member that has been bent into the three-dimensional plate-shaped or sheet member by the folding rollers 42 a and 42 b , to thus support the plate-shaped or sheet member to thereby maintain the plate-shaped or sheet member into a vertically bent shape.
- each of the forming roll sets 40 further comprises upper and lower auxiliary support rollers 43 a and 43 b that are installed at both sides of the upper and lower support rollers 40 a and 40 b , and that auxiliarily support the upper or lower surface or both of the upper and lower surfaces of the plate-shaped or sheet member.
- upper and lower support rollers 40 a and 40 b and the left and right side support rollers 41 a and 41 b are configured to have a cylindrical structure in which the edges of upper and lower support rollers 40 a and 40 b and the left and right side support rollers 41 a and 41 b contact the upper and lower surfaces of the plate-shaped or sheet member or the left and right side surfaces thereof on a surface to surface basis.
- the upper and lower support rollers 40 a and 40 b and the left and right side support rollers 41 a and 41 b are configured to have a disc-shaped structure in which the edges of upper and lower support rollers 40 a and 40 b and the left and right side support rollers 41 a and 41 b contact the bent portion of the plate-shaped or sheet member on a line to line basis.

- the puncher 10 is installed to perform chamfering operations that is required at regular intervals on a V-cut plate-shaped or sheet member, to thereby perform the chamfering operations while unwinding a plate-shaped or sheet member that is wound in a coil form.
- the leveler 20 consists of upper and lower rollers and presses the V-cut plate-shaped or sheet member from the top and bottom portions of the plate-shaped or sheet member, to thereby heighten flatness of the plate-shaped or sheet member and thus produce products of a better quality.

- Flection is formed in the lower roller in correspondence to the shape of the formed plate-shaped or sheet member.
- a reason why the lower roller 30 b of the pinch roll set 30 is formed so as to have a variety of types of flection is because a form of the plate-shaped or sheet member is formed at each manufacturing step, and flection should be formed along with this form of the plate-shaped or sheet member, to accordingly enable the lower roller 30 b to move smoothly.
- pinch roll sets 30 are installed at regular intervals to thus make a plate-shaped or sheet member to be formed move to other forming operation sections smoothly.
- the configuration of the puncher 10 , the leveler 20 , the pinch roll sets 30 , and the electric motor set 50 according to the present invention is the same as that of the conventional art, but the configuration of the forming roll sets 40 that are positioned in the middle of the pinch roll set 30 s differs from that of the conventional art, to thus fundamentally prevent a wave phenomenon of the plate-shaped or sheet member and to thereby complete a product of the bent window/door frame.

Description
- The present invention relates to an apparatus for manufacturing window/door frames or bent metal products, and more particularly, to an apparatus for manufacturing window/door frames or bent metal products, in which the window/door frame or bent metal product manufacturing apparatus is configured to include upper and lower surface support rollers, left and right side support rollers and forming rollers as a forming roll set that forms window/door frames or bent metal products, to thus prevent a reaction force that the forming rollers influence upon a plate-shaped member during a process that the upper and lower surface support rollers and the left and right side support rollers support the plate-shaped or sheet member, and to thereby fundamentally block a wave phenomenon from occurring in the plate-shaped or sheet member that passes through the forming roll set.
- In general, insulation windows/doors have an insulation function and a soundproof function, and are mainly used extensively for general houses, commercial houses, apartment houses, apartment building with stores, offices, etc. Aluminum or PVC is used as a material of the insulation windows or doors. The insulation windows or doors include a sash that is fixed on a wall and a window/door frame that is hinge-combined with the sash. Meanwhile, a structural stainless steel plate-shaped or sheet member for producing the insulation windows/doors is standardized by 1 m wide and 3 m or 4 m long, and sold on the market. However, a window frame of a general commercial store in the first floor is 2.6 m-2.7 m high. Therefore, an expensive stainless steel plate of 3 m long is cut into not more than 2.7 m and then abandoned remnants of 30 cm long or more are disposed as scrap metal. In addition, since the stainless steel plate is standardized to l1 wide, a lot of remnants and leftovers occur when it is cut to be manufactured into a window/door frame, to then become a great cause of rising cost and cause a big waste of resources.
- In addition, a frame bending process includes: the steps of sequentially pressing a V-cut portion of a sheet member with a blade of a folding machine; making a required angle; sequentially turning and bending the sheet member upside down while replacing the blade of the folding machine depending upon a frame, to thereby complete the frame. Further, a fraction defective and a product quality may be determined according to ability of an artisan. Although the conventional frame bending process has the above-described defects, a traditional processing method of bending a window/door frame has been performed by only a bending method using a conventional folding machine.
- Also, the window/door frame that is made using the conventional folding machine is weak in view of soundproof, wind resistance and dustproof, and especially is poor in view of insulation property, to thereby cause energy loss during air-conditioning. Mohair grooves exist in upper and lower H-type bars of a reinforced glass door, respectively, in order to realize soundproof, wind resistance, and dustproof, in which mohair is fitted into the mohair grooves. Here, the H-type bars are stainless steel frames that are fitted in the upper and lower ends of the reinforced glass door to thus protect glass and to make a floor hinge lot attached and fixed to the stainless steel frames. However, there are gaps between the stainless steel frame and the reinforced glass door. Dusts and winds may be easy to come in through the gaps. In order to prevent dusts and winds from coming in through the gaps, paper weather strips or tapes are attached to the stainless steel frame and the reinforced glass door to block the gaps, to accordingly cause poor appearance and no practicality.
- Meanwhile, to solve these problems, the present applicant filed a Korean Patent Application No. 2006-85246 entitled a window/door frame manufacturing apparatus including a pinch roll set and a forming roll set that can make a plate-shaped member for the window/door frame move freely, on Sep. 5, 2006, and registered as a Korean Patent No. 0791647, to thus selectively apply a physical pressure to a bent portion of a product and to accordingly enhance an economical efficiency as well as provide a more convenient manufacturing process.
- By the way, since the plate-shaped member that is formed using the above-described frame manufacturing apparatus, are made to contact the upper and lower structure of the forming roll set, on a surface to surface basis, a physical force is not uniformly transferred to a portion of the plate-shaped member to be bent during bending. As a result, a wave phenomenon that the plate-shaped member becomes uneven has occurred.
- In other words, the conventional forming roll set is designed to make the plate-shaped member contact each other on a surface to surface basis using upper rollers and lower rollers, and to rotate to make the plate-shaped member transformed into an appropriate shape. However, since a forming roll of a portion to be bent is configured into a conical shape, a first half portion and a second half portion of the forming roll set are made to rotate once at an identical time. Accordingly, there is a difference between a distance through which the first half of the forming roll set rotates and a distance through which the second half of the forming roll set rotates. Therefore, since the second half of a big diameter moves farther than the first half during a time that the first half of a small diameter rotates by a shorter distance than the second half, the physical force that is applied to the plate-shaped member is not identical in the first and second halves. As a result, the wave phenomenon occurs during bending the plate-shaped member.
- Finally, since a uniform force is not transferred to the plate-shaped member during bending the plate-shaped member using the conventional forming roll set, the wave phenomenon that the plate-shaped member becomes uneven cannot be avoided.
- To solve the above problems, it is an object of the present invention to provide an apparatus for manufacturing window/door frames or bent metal products, in which a forming roll set adopts upper and lower surface support rollers and left and right side support rollers at the upper and lower portions and the left and right sides of a plate-shaped or sheet member, to thus stably support the plate-shaped or sheet member and to then form window/door frames or bent metal products, and transfers a uniform physical force to the plate-shaped or sheet member, to thereby fundamentally block a wave phenomenon from occurring in the plate-shaped or sheet member that passes through the forming roll set.

- a
puncher 10 that partially punches a V-cut plate-shaped or sheet member to make a chamfer on the V-cut plate-shaped or sheet member; - a
