Description

Technical Field

[0001] This invention relates to the field of shearing device technology, specifically to an adjustable forming shearing device. Background Technology

[0002] In the manufacturing processes of metal sheets, plastic sheets, composite materials, and new energy battery casings, forming and shearing are key pretreatment steps. Traditional shearing equipment (such as gantry shears, swing beam shears, or fixed-spacing double-blade shears) typically employs a rigid blade holder structure, with the blade spacing fixed at the factory. If products of different widths need to be processed, the machine must be stopped to replace the blades or adjust the mechanical limit blocks. This operation is cumbersome, time-consuming, and difficult to adapt to the flexible production needs of multiple varieties and small batches.

[0003] Current cutting devices require stopping the machine and cutting power when adjusting the blade spacing, making it impossible to adjust and cut simultaneously, which seriously affects production continuity. At the same time, the blades on both sides are driven by independent motors, which can easily lead to asynchronous speeds due to uneven loads, resulting in tilted cutting surfaces, increased burrs, and difficulty in adapting to materials of different thicknesses. Thin plates are prone to warping, while thick plates cannot be pressed tightly, resulting in unstable cutting quality. Therefore, we propose an adjustable forming and cutting device. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] This invention discloses an adjustable forming and shearing device, comprising a base, a fixed cover fixedly connected to the top of the base, conveyor belts symmetrically fixedly installed on both sides of the top of the base, protective shells fixedly connected to both ends of the outer side of the fixed cover, a lifting frame slidably connected to one side of the inner side of the fixed cover, fixed frames fixedly connected to both sides of the top of the base, a servo motor fixedly installed at the lower outer side of one of the protective shells, the output end of the servo motor being driven by a bidirectional lead screw via a coupling, rotating shafts rotatably connected inside both fixed frames, and moving blocks fixedly connected to the outer sides of both rotating shafts, with the lower ends of the moving blocks threadedly connected to the bidirectional lead screw via threaded blocks.

[0006] As a preferred embodiment of the present invention, a geared motor is fixedly installed on the upper end of the inner wall of the fixed cover, and the output end of the geared motor is connected to a drive wheel through a coupling. An auxiliary wheel is connected to the outer side of the drive wheel through a synchronous belt.

[0007] As a preferred embodiment of the present invention, a limiting strip is fixedly connected to the outer side of the rotating shaft, and the outer periphery of the limiting strip is engaged with the interior of the auxiliary wheel. Cutting blades are fixedly connected to the inner ends of both rotating shafts.

[0008] As a preferred embodiment of the present invention, the inner center end of the cutting blade is fixedly connected to a cross-shaped limiting rod and a limiting sleeve rod, and the cross-shaped limiting rod and the limiting sleeve rod are engaged. The outer periphery of the center end of the bidirectional lead screw is rotatably connected to a rotating cylinder.

[0009] As a preferred embodiment of the present invention, a rotary motor is fixedly installed on the upper outer periphery of the fixed cover, and the output end of the rotary motor is connected to a drive shaft through a coupling. Both ends of the drive shaft are fixedly connected to bevel gears, and the lower outer periphery of the bevel gears are meshed with bevel gears.

[0010] As a preferred embodiment of the present invention, the inner walls on both sides of the fixing cover are provided with placement grooves, and threaded rods are rotatably connected inside the placement grooves, and the top of the threaded rods is fixedly connected to the bevel gear.

[0011] As a preferred embodiment of the present invention, threaded seats are fixedly connected to both sides of the lifting frame, and the inside of the threaded seats is threadedly connected to the threaded rod. A fixed seat is fixedly connected to the bottom of the lifting frame, and a rotating roller is rotatably connected to the inside of the fixed seat.

[0012] The beneficial effects of this invention are:

[0013] 1. This adjustable forming and shearing device is driven by a servo motor to drive a bidirectional lead screw, which drives the moving blocks and rotating shafts on both sides to move synchronously in opposite directions or away from each other. The distance between the two cutting blades can be adjusted online and steplessly without stopping the machine to change the blades. It can be applied to shearing operations with different bottom frame widths, greatly improving the flexibility of the equipment and production efficiency.

[0014] 2. This adjustable forming and shearing device features an adjustable lifting frame that automatically adjusts its height via a rotary motor, bevel gears, a pair of bevel gears, and a threaded rod. Combined with a freely rotating roller at the bottom, it can apply appropriate clamping force according to the thickness of the sheet material. The rotating roller rotates synchronously with the material as it moves forward, preventing warping and shaking, and avoiding surface scratches. It is suitable for precision shearing of thin sheets, soft materials, or high-gloss materials.

[0015] 3. This adjustable forming and shearing device uses a bidirectional lead screw and a geared motor to handle the spacing adjustment and blade rotation respectively, with no mechanical interference between them. The bidirectional lead screw adjusts the blade position only via a moving block, while the geared motor directly drives the shaft rotation via a synchronous belt and auxiliary wheel, ensuring the independence and reliability of power transmission and improving the overall performance of the equipment. This invention has a simple and reasonable structure, novel design, and is easy and convenient to operate, possessing high practical value. Attached Figure Description

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figures 1-6As shown, the present invention discloses an adjustable forming and shearing device, comprising a base 1, a fixed cover 2 fixedly connected to the top of the base 1, conveyor belts 3 symmetrically fixedly installed on both sides of the top of the base 1, protective shells 4 fixedly connected to both ends of the outer side of the fixed cover 2, a lifting frame 5 slidably connected to one side of the inner side of the fixed cover 2, and fixed frames 6 fixedly connected to both sides of the top of the base 1. A servo motor 7 is fixedly installed at the lower outer side of one of the protective shells 4, and a bidirectional lead screw 8 is driven to the output end of the servo motor 7 through a coupling. Rotating shafts 9 are rotatably connected inside both fixed frames 6, and moving blocks 10 are fixedly connected to the outer side of both rotating shafts 9. The lower ends of the moving blocks 10 are threadedly connected to the bidirectional lead screw 8 through threaded blocks.

[0026] Among them, a geared motor 11 is fixedly installed on the upper end of the inner wall of the fixed cover 2. The output end of the geared motor 11 is connected to the drive wheel 12 through a coupling. The outer side of the drive wheel 12 is connected to the auxiliary wheel 14 through the synchronous belt 13. By using the geared motor 11 to drive the synchronous belt 13, the rotational power is reliably transmitted to the rotating shaft 9 because the inner hole of the auxiliary wheel 14 is engaged with the limiting strip 15 on the outer periphery of the rotating shaft 9.

[0027] Among them, the outer side of the rotating shaft 9 is fixedly connected to the limiting strip 15, and the outer periphery of the limiting strip 15 is engaged with the inside of the auxiliary wheel 14. The inner ends of the two rotating shafts 9 are fixedly connected to the cutting blades 16. The power is reliably transmitted by engaging the limiting strip 15 with the inner hole of the auxiliary wheel 14, avoiding the key connection from loosening and improving the shearing synchronization.

[0028] The inner center end of the cutting blade 16 is fixedly connected to a cross-shaped limiting rod 17 and a limiting sleeve rod 18, and the cross-shaped limiting rod 17 and the limiting sleeve rod 18 are engaged. The outer circumference of the center end of the bidirectional lead screw 8 is rotatably connected to a rotating cylinder 28. The rotation of the bidirectional lead screw 8 can drive the moving block 10 to move along the fixed frame 6, thereby adjusting the distance between the two sets of cutting blades 16. At the same time, the rotation of the bidirectional lead screw 8 will not affect the reduction motor 11 driving the auxiliary wheel 14 through the synchronous belt 13, thereby driving the rotating shaft 9 and the cutting blade 16 to rotate, ensuring the continuity and stability of the shearing process.

[0029] A rotary motor 19 is fixedly installed on the upper outer periphery of the fixed cover 2. The output end of the rotary motor 19 is connected to a drive shaft 20 through a coupling. Both ends of the drive shaft 20 are fixedly connected to bevel gears 21. The lower outer periphery of the bevel gears 21 are meshed with bevel gears 22. The transmission system composed of the rotary motor 19, bevel gears 21 and bevel gears 22 can effectively convert horizontal power into vertical motion, save space, and improve the efficiency and stability of mechanical transmission.

[0030] The inner walls of both sides of the fixed cover 2 are provided with placement grooves 23. Threaded rods 24 are rotatably connected inside the placement grooves 23, and the top of the threaded rods 24 are fixedly connected to the bevel gears 22. The threaded rods 24 in the placement grooves 23 are connected to the transmission system through the bevel gears 22, so that the lifting frame 5 can be adjusted in height as needed to adapt to the processing requirements of materials of different thicknesses, thereby improving the versatility and practicality of the equipment.

[0031] The lifting frame 5 is fixedly connected to threaded seats 25 on both sides, and the inside of the threaded seats 25 is threadedly connected to the threaded rod 24. The bottom of the lifting frame 5 is fixedly connected to a fixed seat 26, and a rotating roller 27 is rotatably connected inside the bottom of the fixed seat 26. The rotating roller 27 ensures the smooth conveying of materials during the shearing process, avoids scratches or damage, and improves the quality of the final product.

[0032] Working Principle: During operation, the sheet material to be sheared is smoothly fed into the fixed cover 2 by a conveyor belt 3 on one side. Based on the sheet thickness and shearing position requirements, the control system starts the rotary motor 19, which drives the threaded rods 24 on both sides to rotate synchronously via the transmission shaft 20, bevel gear 21, and bevel gear 22. This drives the lifting frame 5 to move up and down along the placement groove 23, causing the rotating roller 27 to descend to an appropriate height, applying moderate pressure to the sheet material and effectively preventing warping or vibration during shearing. Subsequently, according to the required shearing width, the servo motor 7 starts, driving the bidirectional lead screw 8 to rotate, causing the moving blocks 10 on both sides and the rotating shaft 9 to move synchronously towards or away from each other, thereby steplessly adjusting the distance between the two cutting blades 16 to adapt to the forming requirements of different product specifications. After adjustment, the reduction motor 11 starts, transmitting power to the rotating shaft 9 via the drive wheel 12, synchronous belt 13, and auxiliary wheel 14. With the cooperation of the limit strip 15, it drives the two cutting blades 16 to rotate synchronously at high speed, precisely shearing the sheet material. The engagement structure between the cross-shaped limiting rod 17 and the limiting sleeve rod 18 ensures that the two blades always rotate synchronously, and the rotating roller 27 rotates freely as the plate moves forward, reducing friction damage; the fixed cover 2 and the protective shell 4 completely enclose the moving parts to ensure the safety of the operator.
