Detailed description of the invention
Fig. 1 is a kind of compound roll forming machine of plate rolling electricity-saving lamp reflector, is made up of support, wallboard, motor, reductor, sprocket wheel, chain, gear, upper rolling axle, lower rolling axle and rolling wheel.This compound roll forming machine is specifically designed to the rolling and forming of electricity-saving lamp reflector cross sectional shape as shown in Figure 7.
As shown in Figure 7, electricity-saving lamp reflector is the part being made up of strip multiple folding face, and it forms through panel beating with sheet metal.The technological requirement of product is that shape meets, dimensionally stable, smooth surface, has good reflecting surface and illumination reflecting effect.
Support 1 is elongated rectangular shape cubic shaped, is provided with left wallboard 12 and right wallboard 13 at support end face along the longitudinal left and right sides of support, is provided with the 23 breaker roll wheels arranged from front to back along material movement direction in left and right sidesing wall plate.
As shown in Figure 2, on the left of support, sprocket drive system is provided with.The variable-frequency motor 2 be fixed on below support 1 is connected with reductor 3, speed reducer output shaft is equipped with lower sprocket 4, the upper sprocket wheel that lower sprocket 4 is located on left wallboard 12 by chain drive rotates, upper sprocket wheel is arranged on the 11st on the left wallboard 12 between 12 breaker roll wheels, upper sprocket wheel and idler gear 5 are coaxial to be installed and synchronous axial system, and idler gear drives respectively and is positioned at the lower gear 6 that its both sides are contained on lower rolling axle 8 and rotates.
On left wallboard 12, an idler gear 5 is all equipped with in the centre position of each breaker roll wheel, idler gear engages with the lower gear 6 on rolling axle 8 under being fixed on being positioned at its both sides respectively, be fixed on lower gear on lower rolling axle 8 except 7 engaging with cogging, also engage with other idler gears being positioned at its both sides respectively, the transmission system that so formation one is complete.
As shown in Figure 3, lower gear 6 is rotated by rolling axle 9 in 5 drivings that cog that are fixed on upper rolling axle 9.Upper rolling axle 9 and lower rolling axle 8 drive topping roll 11 fixed thereon and bottom roll 10 to rotate respectively.In addition, the idler gear of both sides drives all the other each breaker roll wheels to rotate respectively.
In the diagram, often pair of rolling wheel is made up of topping roll 11 and bottom roll 10, and topping roll and bottom roll are setting up and down and are separately fixed on rolling axle 9 and lower rolling axle 8.The two ends of upper rolling axle and lower rolling axle are fixed on the wallboard of the left and right sides respectively by bearing.
As shown in Figure 5, the cross section of topping roll 11 and bottom roll 10 is provided with suitable concaveconvex shape, makes the contact surface of topping roll 11 and bottom roll 10 for occlusion shape.
The profile design of the contact surface of topping roll 11 and bottom roll 10 is the shape of sheet material after roll forming, as seen from Figure 6, the Changing Pattern of the concaveconvex shape of the contact surface of the 1st to the 20th right topping roll 11 and bottom roll 10 is, the concaveconvex shape of the contact surface of topping roll 11 and bottom roll 10 is progressively deepened from front to back, also mean that the degree of plate rolling is deepened successively gradually, progressively gradual change is shaping to make institute's rolling electricity-saving lamp reflector grooved as shown in Figure 7.The above-mentioned many rolls of this employing make sheet material be out of shape gradually to design with the composite roll roll process of alternating bending, can eliminate the internal stress influence of sheet material preferably, make the electricity-saving lamp reflector grooved size of institute's rolling accurate, stable molding.
For different shape of products, the concaveconvex shape of topping roll and bottom roll can design according to the finished form of rolling.
Employing variable-frequency motor controls, and can ensure transmitting power velocity-stabilization, guarantee the accuracy of manufacture of product.
For guaranteeing that sheet material enters the top and bottom rolls of roller mill with correct attitude, the feed end of this machine is also equipped with inlet guide device 15.Inlet guide device is made up of frame, support roller and guide wheel.Below frame, be installed with multiple support roller side by side, also guide wheel be housed in frame both sides.During charging, top sheet material being placed in support roller is carried forward, and the guide wheel of both sides prevents crooked to sheet material constraint, and sheet material is entered between the top and bottom rolls of the first breaker roll wheel smoothly.
Protective cover 14 is housed on the left of support, and the upper lower gear of sprocket drive system and each upper rolling axle and lower rolling axle hides by protective cover completely, ensure that security during machine run.
For ensureing technological requirement, its middle gear adopts 40Cr forging and through flank of tooth high-frequency quenching and case hardness HRC42-48, rolling axle selects 40Cr forging through the modified HB=280-320 of nodularization, rolling wheel selects Cr12Mov material to make, through forging, spheroidizing, surface hardening, tempering, case hardness reaches HRC58-62.
The present embodiment has following characteristics:
