Technical Field

[0001] This utility model relates to the technical field of stamping feeding devices, and in particular to a sheet metal mold stamping feeding device. Background Technology

[0002] Sheet metal stamping is a stamping technology used for mass production of sheet metal parts. It typically uses steel strip as raw material. In order to improve stamping quality and reduce material waste, it is necessary to use a specialized feeding device to transport the steel strip.

[0003] Existing stamping feeding devices, such as the Chinese utility model patent with authorization announcement number CN222818503U for a feeding machine, represent a class of prior art. Their main structure includes a material rack, a drive assembly, and a tensioning assembly. The material rack holds the steel strip, the drive assembly clamps and transports the steel strip, and the tensioning assembly tensions the steel strip.

[0004] However, the existing technology and equipment still have the following problems when in use: the existing machines require workers to manually tighten the steel strip, which is inconvenient to control the tightening force, resulting in poor machine conveying effect. In addition, the existing machines only use a single motor to drive a single tightening point to convey the steel strip, resulting in poor conveying accuracy. Utility Model Content

[0033] First, the steel strip coil is placed on the unwinding roller 22. Then, the end of the steel strip is passed from the rear and bottom over the two tension rollers 23 and inserted between the flattening conveyor rollers 27. Next, hydraulic cylinder 1 24 is opened, providing power to drive the brackets 6 26 to move closer or further apart. When the brackets 6 26 move closer together, the flattening conveyor rollers 27 and the auxiliary flattening rollers 28 work together to clamp the steel strip. Afterward, hydraulic cylinder 2 42 is opened, providing power to drive the bracket 7 43 to move back and forth.

Tensioning is performed using sprockets 344, 46, 47, 48, and 49, which work together to ensure efficient power transmission between sprockets 1 and 32 on both sides. Then, motor 135 is activated, providing power that is transmitted through sprockets 1 and 32, chain 13, reducer 134, sprocket 236, and chain 237. This drives the tension roller 23 and the flattening conveyor roller 27 to rotate at equal linear speeds, improving the machine's stability in conveying the steel strip. The flattening conveyor roller 27 rotates to flatten and transport the steel strip, with rotational damping. Device 21 provides rotational damping to the unwinding roller 22 to prevent the steel strip on the unwinding roller 22 from loosening during rotation. Tensioning roller 23 tensions the steel strip. At the same time, tensioning roller 23 and flattening conveyor roller 27 cooperate to bend the steel strip in the opposite direction to relieve stress. Assisting flattening roller 28 fills the gap between flattening conveyor rollers 27 to prevent deformation of the steel strip at this point and improve the flattening effect of flattening conveyor roller 27. Meanwhile, friction wheel 54 presses against the upper surface of the steel strip under the elastic force of spring 52. Friction wheel 54 rotates with the movement of the steel strip. Angular displacement sensor 53 monitors friction wheel 54. The rotation angle of 4 is measured to measure the conveying length of the steel belt in real time, which facilitates feedback control of the steel belt conveying and improves the conveying accuracy of the steel belt. Then, the second motor 71 is turned on, and the second motor 71 provides power to drive the gear pump 69 to pump the lubricating oil in the oil tank 68 into the hollow rotating shaft 64 through the oil pipe 67 and the rotating joint 66. The sponge layer 65 absorbs the lubricating oil through its own structure. At the same time, the steel belt and the second spring 63 squeeze the sponge layer 65, causing the sponge layer 65 to rotate and apply the lubricating oil to the surface of the steel belt.

[0034] like Figures 1 to 6As shown, this utility model discloses a sheet metal mold stamping feeding device. During operation, the steel strip coil is first placed on the unwinding roller 22. Then, the end of the steel strip is passed from the rear and bottom over two tension rollers 23 and inserted between the flattening conveyor rollers 27. Next, hydraulic cylinder 1 24 is activated, providing power to drive brackets 6 26 to move closer or further apart. When brackets 6 26 move closer together, the flattening conveyor rollers 27 and auxiliary flattening rollers 28 cooperate to clamp the steel strip. Then, hydraulic cylinder 2 42 is activated, providing power to drive bracket 7 43 to move back and forth. The rearward movement of frame 7 (43) drives sprocket 3 (44) to move backward, tensioning chain 3 (49). The cooperation of sprocket 3 (44), sprocket 4 (46), sprocket 5 (47), tension baffle 48, and chain 3 (49) ensures efficient power transmission between sprocket 1 (32) on both sides. Then, motor 1 (35) is activated, providing power. This power is transmitted through sprocket 1 (32), chain 1 (33), reducer 1 (34), sprocket 2 (36), and chain 2 (37), driving tension roller 23 and flattening conveyor roller 27 to rotate at equal linear speeds. This improves the machine's stability in conveying the steel strip. The flattening conveyor roller 27 rotates... The steel strip is conveyed and leveled. Rotation damper 21 provides rotational damping to unwinding roller 22 to prevent the steel strip on unwinding roller 22 from loosening during rotation. Tensioning roller 23 tensions the steel strip. Simultaneously, tensioning roller 23 and flattening conveyor roller 27 work together to reverse-bend the steel strip to relieve stress. Assist flattening roller 28 fills the gaps between flattening conveyor rollers 27 to prevent deformation of the steel strip at these points, improving the leveling effect of flattening conveyor roller 27. Meanwhile, friction wheel 54 presses against the upper surface of the steel strip under the elastic force of spring 52. Friction wheel 54 rotates with the movement of the steel strip. An angular displacement sensor... The rotation angle of the friction wheel 54 is measured by 53, thereby measuring the conveying length of the steel belt in real time. This facilitates feedback control of the steel belt conveying and improves the conveying accuracy of the steel belt. Then, the second motor 71 is turned on, which provides power to drive the gear pump 69 to pump the lubricating oil in the oil tank 68 into the hollow rotating shaft 64 through the oil pipe 67 and the rotating joint 66. The sponge layer 65 absorbs the lubricating oil through its own structure. At the same time, the steel belt and the second spring 63 squeeze the sponge layer 65, causing the sponge layer 65 to rotate and apply the lubricating oil to the surface of the steel belt.

[0035] The two rotation dampers 21, hydraulic cylinder 24, twelve sprockets 32, eight chains 33, motor 35, four sprockets 36, two chains 37, two hydraulic cylinders 42, two sprockets 44, six sprockets 46, two chains 49, two springs 52, angular displacement sensor 53, two springs 63, rotary joint 66, gear pump 69, and motor 71 of this utility model are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0036] The main function achieved by this utility model is: by setting up power device 1 03 and power device 2 04, the multiple contact points between the machine and the steel belt rotate at the same linear speed, thereby improving the stability of the steel belt transportation and thus improving the transportation accuracy; it solves the existing technical problems that require workers to manually tighten the steel belt, which is inconvenient to control the tightening force, resulting in poor machine transportation effect, and that the existing machines only use a single motor to drive a single tightening point to transport the steel belt, resulting in poor transportation accuracy.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
