Description

TECHNICAL FIELD

[0001] The present invention relates to a louver press, more particularly to a louver press, a system thereof and a method of manufacturing a louver. BACKGROUND

[0002] When the louver blades are made of PVC sheets, they are usually manufactured through an extrusion process. Extrusion is a common plastic processing method, and it is a relatively economical and efficient manufacturing method suitable for mass production of products such as shutters. This method can ensure the uniformity and consistency of the blades, and at the same time make the production process easier to control.

[0003] When the louver blades are made of aluminum alloy sheets, a deep drawing forming process is usually used. Deep drawing forming is suitable for producing a large number of metal blades, and this process can provide high manufacturing precision and consistency. At the same time, aluminum alloy has the characteristics of light weight, corrosion resistance, etc., making it an ideal material for making louver blades.

[0004] The forming of aluminum alloy sheets using a stretch die usually involves higher costs. This is because stretch forming is a relatively complex metal forming process, involving specialized die design and manufacturing, as well as a highly controlled production process. The following are some factors that contribute to higher costs:

[0005] Die manufacturing: The design and manufacture of dies for stretch forming is expensive. These dies must accurately conform to the required blade shape, while also taking into account factors such as material flow, stress distribution, etc. The manufacture of dies usually requires a lot of time and resources.

[0006] Equipment and process control: Stretch forming usually requires specialized equipment and process control systems to ensure the stability and consistency of the production process. The investment in these equipment and systems also increases costs.

[0007] Scrap rate: Because metal undergoes complex deformation during stretching, more engineering and adjustments are usually required to control the forming process to avoid defects and scrap. The increase in scrap rate will lead to an overall increase in cost.

[0008] Material cost: Although aluminum alloy itself is relatively light, some special alloys or manufacturing requirements may increase the cost of materials. In addition, for aluminum alloy sheets, surface treatment (such as anodizing) may also increase costs.

[0009] Although the cost of stretch forming is relatively high, this method is usually used to produce large quantities of aluminum alloy blades with high precision requirements. The cost can be spread and reduced through large-scale production and process optimization, so for large-scale production, stretch forming may still be an economically reasonable choice.

[0010] Considering the service life of the shutter, the material of aluminum alloy is more inclined to be used, but since the shutter blade of aluminum alloy is suitable for mass production when it is formed by stretching, and at present customers more and more like individual customization, the demand for shutter blades tends to diversification and small batch production, and the use of the previous stretching die forming process will increase the cost. Therefore, the inventor believes that it is necessary to develop a new shutter blade production equipment and process to realize low-cost small batch production and better meet the needs of customers.

Synchronous punching and cutting operations can also be realized. The movable vertical mold base is used to realize the cutting and punching operations while rolling, thereby improving the production efficiency. The specific description is as follows:

[0025] The present invention uses rolling wheels to press flat, elongated metal sheets into metal profiles with cross-sectional shapes, bringing the following technical effects:

[0026] Different cross-sectional shaping: The design of the rolling wheels allows the metal sheet to achieve different cross-sectional shapes after passing through multiple sets of rolling wheels in succession. This shaping process enables the metal profile to meet various design requirements, including special cross-sectional shapes, concave and convex parts, etc.

[0027] Material saving: Rolling processing can achieve a relatively uniform thickness of the metal sheet while changing the cross-section through a continuous pressing process. This helps to maximize the use of raw materials, reduce waste generation, and improve resource utilization efficiency.

[0028] High precision: Rolling wheels can usually be precisely controlled to achieve highly precise metal profile sizes and shapes. This helps to ensure that the produced metal profile meets the design specifications, improving production consistency and quality.

[0032] Reducing processing steps: Integrating cutting and punching into one step reduces the processing steps in the production process. This helps to simplify the production line and reduce production costs.

[0033] Improving precision: Performing punching operations immediately after cutting ensures that the position and size of the punch match the accuracy and consistency of the cut aluminum alloy sheet. This helps to improve the precision and consistency of the product.

[0034] Reducing scrap rate: By performing punching immediately after cutting, errors and scrap rates caused by secondary processing steps can be reduced. This helps to improve production line efficiency and reduce costs.

[0035] Improving the flexibility of the production line: By performing punching after cutting, it can be more flexible to adapt to different product specifications and design requirements, thereby improving the flexibility of the production line.

[0036] Further adoption of the vertical die holder can perform cutting operations simultaneously with rolling operations, with the following effects:

[0037] Increased production efficiency: Since the rollers do not need to be stopped, cutting can be performed simultaneously during rolling, reducing production interruption time, which helps to improve production efficiency.

[0038] Energy saving: Without the need to stop the rollers and restart, energy consumption during equipment start-up and stoppage can be reduced, improving the energy efficiency of the equipment.

[0039] Reduced equipment wear: Under normal circumstances, starting and stopping equipment can cause additional wear, and by cutting simultaneously during rolling, unnecessary mechanical movements can be reduced, prolonging the service life of the equipment.

[0040] Improved product consistency: Continuous production flow can improve product consistency, as changes caused by start-up and stoppage do not occur during cutting. This is very important for ensuring the quality and consistency of the final product specifications.

[0041] Reduced scrap rate: Continuous cutting can reduce the scrap rate caused by mechanical vibration and instability during cutting. This helps to improve production line efficiency and reduce costs.

[0042] Easy operation: The structure of cutting and rolling at the same time may make the operation more simple, reducing the switching operation between cutting and rolling, improving the ease of use of the equipment.

[0043] Such a structure can not only be used for the rolling and forming of louver blades, but also for the synchronous cutting operation after continuous traction of other articles. BRIEF DESCRIPTION OF DRAWINGS

[0085] To better understand the technical content of the present invention, the technical solution of the present invention will be further introduced and explained below with reference to specific embodiments, but is not limited thereto.

[0086] like Figure 2 The specific embodiment shown is an embodiment with only cutting function: The leaf forming machine of the present invention includes a base 10 with a vertical mounting surface. One end of the vertical mounting surface is provided with a material rack 20 for mounting rolled metal sheets S0, and the other end is provided with a punching device 30, and a rolling device 40 is provided between the material rack 20 and the punching device 30. The rolling device 40 includes several sets of rolling rollers to press the flat metal sheet into a metal profile with a cross-sectional shape to form a louvered curtain. The punching device 30 includes a lower die base 31 and an upper die base 32 fixed to the base 10. The upper die base 32 is provided with a punching upper die and a punching power component for driving the punching upper die. The lower die base 31 is provided with a punching lower die.

[0087] Specifically, the punching power component includes a cutting power component 321, the punching upper die includes a cutting upper die 322 fixed to the lower end of the cutting power component 321, and the punching lower die includes a cutting lower die 311; the lower end of the cutting power component 321 is further provided with a cutting pre-pressing block 323 located on the feeding side of the cutting upper die 322.

[0088] In this embodiment, taking an aluminum alloy louver blade with a thickness of 0.2 mm and a width of about 10 mm as an example, the plurality of sets of rolling wheels include four sets of primary shaping wheels 41 with substantially similar sizes, the outer circles of which have shapes for pressing the primary shape of the louver; one set of secondary shaping wheels 42 with smaller sizes, the outer circles of which have shapes and can further shape; and one set of shaping wheels 43 with even smaller sizes, the outer circles of which have shapes and can finally shape. The plurality of sets of rolling wheels can be driven by the same motor through gear transmission structure for deceleration, or can be driven by multiple motors respectively. In other embodiments, the metal sheet can also be made of other materials, such as copper or iron-based sheet.

[0089] The rolling device 40 further includes an adjusting seat 44 located on the feeding side of the plurality of sets of rolling wheels, to adjust the up-down and left-right positions of the metal sheet to align the positions of the rolling wheels. The adjusting seat 44 is fixed to the machine base 10, and the up-down and left-right position adjustments thereof can be achieved by a screw rod structure with locking nuts, which will not be described herein.

[0090] In order to guide the louver blade, a lower guide plate 310 fixed to the lower die seat 31 and an upper guide plate 320 fixed to the upper die seat 32 are arranged at the feeding end of the punching device 30. The lower guide plate 310 and the upper guide plate 320 form a guide cavity slightly larger than the metal profile, which guides the metal profile after shaping. The upper die seat 32 is also provided with an upper guide plate 329 between the cutting power component and the punching power component.

[0091] Figure 2 The structure of the rolling device 40, by using rolling wheels to press the planar elongated metal sheet into a metal profile with a cross-sectional shape, brings the following technical effects:

[0092] Different cross-sectional shaping: The design of the rolling wheels allows the metal sheet to achieve different cross-sectional shapes after passing through the continuous plurality of sets of rolling wheels. Such a shaping process enables the metal profile to meet various design requirements, including special cross-sectional shapes, concave-convex parts, etc.

[0093] Material saving: The rolling process can change the cross section of the metal sheet while maintaining a relatively uniform thickness through a continuous pressing process. This helps to maximize the use of raw materials, reduce waste, and improve resource utilization efficiency.

[0094] High precision: The rolling wheel can usually be precisely controlled to achieve highly precise metal profile sizes and shapes. This helps ensure that the produced metal profiles meet design specifications, improving production consistency and quality.

[0095] Surface quality: Rolling processing can provide relatively smooth surface quality without the need for additional surface treatment. This helps reduce production costs and reduce subsequent processing steps.

[0096] As Figure 3 The second embodiment shown in the specific embodiment is only a cutting function, and its further structure is that the punching power element 326 is further provided on the discharge side of the cutting power element 321, the punching upper die 327 is further fixed to the lower end of the punching power element 326, and the punching lower die 316 is further provided on the lower die seat 31; The lower end of the punching power element 326 is further provided with a punching pre-pressing block 328 located on the feeding side and the discharging side of the punching upper die 327; The lower die seat 31 is further provided with a plurality of springs 317 for supporting the punching lower die 316; During operation, the punching lower die 316 descends at the same time as the cut metal profile S1, and when the metal profile S1 is completely cut, the punching lower die 316 is stopped from descending by the bottom of the stroke groove 319 provided on the lower die seat 31, the punching upper die 327 descends into the die hole 315 of the punching lower die 316, and the required through hole is punched out. This through hole is the rope hole for the blind curtain piece, and for other products, it may be other functional holes. Because the rope hole of the blind curtain piece is generally two, the punching upper die 327 in this embodiment is two, and the die hole 315 above the punching lower die 316 is also two.

[0097] Therefore, by further adopting the punching upper die and the punching lower die, the punching operation can be performed at the same time as the cutting, which has the following technical effects:

[0098] Integrated production: The punching operation is performed immediately after cutting, which realizes an integrated production process. This helps reduce intermediate steps, improve production efficiency, and reduce the overall production cycle.

[0099] Reducing processing steps: Integrating cutting and punching into one step reduces the processing steps in the production process. This helps simplify the production line and reduce production costs.

[0100] Improving precision: The punching operation is performed immediately after cutting, which ensures that the position and size of the punching match the accuracy and consistency of the cut aluminum alloy sheet. This helps improve the precision and consistency of the product.

[0101] Reducing waste rate: By performing punching immediately after cutting, errors and waste caused by secondary processing steps can be reduced. This helps improve production line efficiency and reduce costs.

[0102] Improving the flexibility of the production line: By punching after cutting, it can be more flexible to adapt to different product specifications and design requirements, thereby improving the flexibility of the production line.

[0103] In the above Figure 2 and Figure 3 Embodiments, further comprising a length measuring wheel 451 arranged on the feed side of the plurality of sets of rolling wheels, and a length measuring pressure wheel 452 in pressure contact with the length measuring wheel 451, the length measuring wheel 451 being coupled with an encoder 453 to detect the length of the metal profile when cutting, and when the set length is reached, stop the power output of the rolling wheels and perform the punching operation.

[0104] Figure 4 Embodiment three is to arrange the length measuring wheel 451 on the discharge side of the plurality of sets of rolling wheels, which can further reduce the dimensional error, because after the metal sheet is pressed and formed by the rolling wheels, it will be extended in the length direction.

[0105] In other embodiments, two length measuring wheels can be arranged on the feed side and the discharge side of the plurality of sets of rolling wheels respectively, to detect the length before the rolling wheels and the length of the rolling wheels respectively, so as to obtain the error value of the two, which can be used as reference data when designing the rolling wheels, or for the rolling wheel technicians to verify whether the design structure is corrected.

[0106] The photoelectric switch 39 (as shown in Figure 7 ) can also be arranged on the discharge end of the upper die holder 32, and when the metal profile S1 is detected, the power output of the rolling wheels can be stopped and the punching operation can be performed in the embodiments of Figure 2 , Figure 3 , Figure 4 In the embodiments of Figure 5 and Figure 7 , the horizontal power mechanism starts to work, synchronizing the vertical die holder with the metal profile, and then performing the punching operation. The photoelectric switch is arranged on the upper die holder, which can reduce the influence of the punching action. The general accuracy of the photoelectric switch can reach about 0.1 mm, which can meet the requirements of length calculation.

[0107] The above three ways of calculating the length of the metal profile cutting are the best with the photoelectric switch, because when the length measuring wheel slips, it is not easy to detect, which leads to an increase in the scrap rate.

[0108] Figure 5 and Figure 6The embodiment four uses a movable die holder, and the die holder for punching can move synchronously while rolling, so as to achieve the purpose of rolling and punching at the same time. The specific structure is that: the vertical die holder 50 is horizontally slidably connected with the machine base 10; the upper die holder 32 and the lower die holder 31 are both fixed to the vertical die holder 50; the horizontal power mechanism 60 is arranged between the vertical die holder 50 and the machine base 10, and when the detection length of the encoder 453 reaches the set value, or when the photoelectric switch 39 detects the metal profile S1, the horizontal power mechanism 60 starts to work to move the vertical die holder 50, and the horizontal moving speed is the same as the linear speed of the several groups of rolling wheels; after the metal profile S1 is cut off and the punching upper die is raised, the horizontal power mechanism 60 works reversely to push the vertical die holder 50 to retreat back to the starting position.

[0109] More specifically, the machine base 10 is provided with an upper horizontal slide rod 19 and a lower horizontal slide rod 18, and two upper slide rod seats 191 for fixing the upper horizontal slide rod 19 and two lower slide rod seats 181 for fixing the lower horizontal slide rod 18; the horizontal power mechanism 60 includes a lead screw 61 arranged between the two lower slide rod seats 181 (or between the two upper slide rod seats), a horizontal power motor 62 for driving the lead screw 61, and a nut seat 63 fixed to the vertical die holder 50 and matched with the lead screw 61. The vertical die holder 50 is further provided with two upper slide rod holes 59 matched with the upper horizontal slide rod 19 and two lower slide rod holes 58 matched with the lower horizontal slide rod 18.

[0110] The machine base 10 is provided with a lower supporting plate 108 for mounting the lower slide rod seat 181, and a lower rib plate 109 arranged below the lower supporting plate 108 to form a stable fixing structure.

[0111] During the working process, the cut-off metal profile can be sent to the discharge box of the subsequent rolling formed metal profile or the next process under the pushing of the subsequent rolling formed metal profile. In order to reduce the interference between the metal profiles, the embodiment five shown in the figure can be provided with a pair of feeding wheels 314 at the discharge end of the punching lower die 316, and a feeding motor 313 connected with the feeding wheels 314, so as to convey the cut-off metal profile S1 to the discharge end of the discharge box or the next process. Figure 7

[0112] ​In further embodiments, the surface shape of the feeding wheel matches the metal profile, and in the stop state, the outer surface of the feeding wheel has a small gap with the metal profile, so that the metal profile is not blocked when it is fed between the two feeding wheels. In the rotating working state, one of the feeding wheels is provided with a centrifugal expansion mechanism, so that the outer diameter of the elastic rubber wheel is expanded to form a friction force with the metal profile, thereby feeding the metal profile out. The feeding wheel with the centrifugal expansion mechanism is made of an elastic material such as rubber, and is provided with an annular groove, about 3-6 fan-shaped metal blocks are arranged in the annular groove, the metal blocks are connected together by springs or are clamped by an annular spring. When stationary, the metal blocks are contracted together, and when rotating, the gap between the metal blocks increases under the action of centrifugal force, thereby being in pressure contact with the surface of the metal profile and forming a friction force to feed the metal profile out. The two feeding wheels are meshed by gears at one end, and the other end of one of the feeding wheels is connected with a feeding motor.

[0113] Since different metal profiles require replacement of the rolling wheel, the cutting upper die, the cutting lower die, the punching upper die, and the punching lower die, in order to facilitate replacement, Figure 7 In the embodiment, the lower die seat 31 adopts a split structure, as shown in Figure 8 The lower die seat body 300 is further provided with a lower L-shaped groove 309. The lower die seat connecting block 301 is detachably connected to the discharge end of the lower die seat body 300. The inner side of the lower die seat connecting block 301 is provided with a straight groove to form a travel groove 319 on the discharge side. The feed side of the lower die seat body 300 is provided with an upper L-shaped groove 308. The cutting lower die 311 is detachably fixed to the feed end of the lower die seat body 300 and forms a travel groove 319 on the feed side with the upper L-shaped groove 308. The spring 317 is further positioned by the guide pin 37 fixed in the lower L-shaped groove 309. The punching lower die 316 is provided with a guide hole 3160 corresponding to the guide pin 37. The two ends of the punching lower die 316 are further provided with protruding parts embedded in the travel groove 319. In order to improve the support force of the punching lower die 316 during punching and make the support force more uniform (prevent the punching lower die 316 from being deformed under force during punching), the position of the guide pin 37 and the guide hole 3160 can be used to determine the descending termination position of the punching lower die 316.

[0114] Taking a 0.2 mm thick, about 10 mm wide blind curtain piece as an example, the cutting and punching forces required for cutting and punching are small. The cutting power element and the punching power element preferably adopt a cylinder structure, which is simple in structure and low in cost. When the blind curtain piece is thickened or used for pressing forming of other products with higher strength, an oil cylinder structure can be used.

[0115] Since different blind curtain pieces have different punching positions, the upper die seat is provided with a longitudinally extending mounting cavity (i.e., the Figures 2-7The vertical position of the punching power component can be adjusted when processing different types of blind pieces (left-right direction in the figure).

[0116] With the vertical mold base, the cutting operation can be performed simultaneously with the rolling operation, resulting in the following effects:

[0117] Improved production efficiency: Since the rollers do not need to be stopped, cutting can be performed simultaneously during rolling, reducing production downtime, which helps improve production efficiency.

[0118] Energy saving: Without the need to stop the rollers and restart, energy consumption during equipment start-up and stoppage can be reduced, improving the energy efficiency of the equipment.

[0119] Reduced equipment wear: Under normal circumstances, starting and stopping equipment can cause additional wear and tear, but by cutting simultaneously during rolling, unnecessary mechanical movements can be reduced, extending the life of the equipment.

[0120] Improved product consistency: Continuous production flow can improve product consistency, as changes caused by start-up and stoppage during cutting will not occur. This is very important for ensuring the quality and consistency of the final product.

[0121] Reduced scrap rate: Continuous cutting can reduce the scrap rate caused by mechanical vibration and instability during cutting. This helps improve production line efficiency and reduce costs.

[0122] Easy to operate: The structure of cutting and rolling at the same time may make the operation more simple, reducing the switching operation between cutting and rolling, improving the ease of use of the equipment.

[0123] Such a structure can not only be used for the rolling and forming of blind pieces, but also for the synchronous punching operation after the continuous traction of other objects.
