Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically to an energy-saving shearing machine. Background Technology

[0002] Following the Industrial Revolution, with the large-scale production and application of steel and other metal materials in construction, machinery manufacturing, railway transportation, and many other fields, the cutting and segmentation of sheet metal became a necessity. Early on, manual shearing was the most primitive method. Craftsmen used large scissor-like tools, relying on their arm strength to open and close the blades to cut, resulting in extremely low efficiency and inconsistent cut quality, failing to meet the growing industrial demand for batch and precise sheet metal cutting. With a deeper understanding of mechanical principles and the widespread availability of simple mechanical devices, manual shearing tools with lever-like structures to increase shearing force emerged, improving operational convenience and slightly increasing work speed to some extent. However, they were still limited to processing thin, small-sized sheets, and the labor intensity remained high. From the late 19th to the mid-20th century, mechanically driven shearing machines began to appear. These shearing machines relied on a motor drive, transmitting power through belts, gears, drive shafts, and other transmission components to make the blade holder and cutting edge move in a reciprocating linear motion to achieve shearing. The advantage was a significant leap in efficiency compared to manual methods.

[0003] Existing shearing machines can only change the cutting angle by changing the blades. This invention solves the above problem. Utility Model Content

[0004] This invention addresses the technical problem that existing shearing machines can only change the cutting angle by replacing the blades, and provides an energy-saving shearing machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving shearing machine, comprising: a shearing blade, one end of which is hinged to a movable blade holder via a pin, and the other end of which is connected to a ring tooth. The ring tooth and the pin are concentrically arranged, and the ring tooth meshes with a gear. A locking adjustment structure can control the rotation and locking of the gear. The locking adjustment structure is connected to the movable blade holder, which is slidably connected to a slide rail. The movable blade holder is connected to a reciprocating mechanism. The slide rail is connected to the upper surface of the worktable, and a fixed blade is connected to the worktable. The shearing blade can cooperate with the fixed blade to shear the plate.

[0006] Preferably, the locking adjustment structure includes a worm gear rotatably connected to a moving tool holder. A motor bracket is connected to the moving tool holder, and a motor is connected to the motor bracket. The motor output end is connected to the worm gear, which meshes with a worm wheel. The worm wheel is connected to a rotating shaft, which is rotatably connected to a bearing housing. The bearing housing is connected to the moving tool holder, and the other end of the rotating shaft is connected to a gear.

[0007] Preferably, the shearing blade has multiple arc-shaped grooves, which are concentrically arranged with the pin shaft. The moving blade holder has holes, and the stud can pass through the arc-shaped grooves and the holes of the moving blade holder and be fastened by a nut.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] During adjustment, the locking adjustment structure drives the shearing blade to rotate around the pin shaft through the gear and ring gear engagement. After adjustment, the shearing blade is locked, completing the blade angle adjustment. When shearing different types of materials, switching the blade angle achieves the best shearing effect, saving energy and improving efficiency.

[0010] By using multiple bolts to fasten the shear blade to the moving blade holder, the force on the locking adjustment structure during shearing is reduced, thus extending the service life of the mechanism. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0016] The present invention will now be described in detail with reference to the accompanying drawings. Example

[0017] The following is combined with Figure 1-2This embodiment describes an energy-saving shearing machine, comprising: a shearing blade 1, one end of which is hinged to a movable blade holder 3 via a pin 2, and the other end of which is connected to a ring tooth 4. The ring tooth 4 is concentrically arranged with the pin 2 and meshes with a gear 5. A locking adjustment structure 6 can control the rotation and locking of the gear 5. The locking adjustment structure 6 is connected to the movable blade holder 3, which is slidably connected to a slide rail 7. The movable blade holder 3 is connected to a reciprocating mechanism. The slide rail 7 is connected to the upper surface of a worktable 8. A fixed blade 9 is connected to the worktable 8, and the shearing blade 1 can cooperate with the fixed blade 9 to shear the plate.

[0018] The flat blade of a shearing machine provides a very smooth shearing surface, making it ideal for applications requiring extremely high flatness, such as processing thin sheets for precision electronic device housings and cutting high-end decorative panels. Compared to a flat blade, an oblique blade requires significantly less shearing force because it cuts through the entire thickness of the sheet in stages, not all at once. This allows oblique blade shearing machines to cut relatively thicker sheets. During operation, a reciprocating mechanism drives the moving blade holder 3 to slide back and forth along the slide rail 7. The reciprocating mechanism utilizes existing... The reciprocating function is achieved using a commonly used hydraulic cylinder or eccentric wheel. The moving blade holder 3 drives the shearing blade 1 to cooperate with the fixed blade 9 in shearing. When adjusting the blade angle, the locking adjustment structure 6 drives the gear 5 to rotate. The rotation of gear 5 drives the ring gear 4 to rotate. The ring gear 4 drives the shearing blade 1 to rotate around the pin 2, thus adjusting the angle of the shearing blade 1. After the adjustment is completed, the locking adjustment structure 6 controls the gear 5 to lock, thus fixing the blade angle of the shearing blade 1. This completes the switching between flat blade and oblique blade without reassembly. By adjusting the blade angle, the shearing force is reduced, achieving energy saving, saving blade changing time, reducing costs and improving efficiency.

[0019] The locking adjustment structure 6 includes a worm gear 61, which is rotatably connected to the moving tool holder 3. A motor bracket 62 is connected to the moving tool holder 3, and a motor is connected to the motor bracket 62. The output end of the motor is connected to the worm gear 61. The worm gear 61 is meshed with a worm wheel 63, which is connected to a rotating shaft 64. The rotating shaft 64 is rotatably connected to a bearing seat 65, which is connected to the moving tool holder 3. The other end of the rotating shaft 64 is connected to a gear 5.

[0020] When adjusting the cutting edge angle, the motor drives the worm 61 to rotate, the worm 61 drives the worm wheel 63 to rotate, the worm wheel 63 drives the rotating shaft 64 to rotate, and the rotating shaft 64 adjusts the gear 5 to rotate to achieve adjustment. Under the self-locking action of the worm 61 and the worm wheel 63, the gear 5 is locked.

[0021] The shearing blade 1 has multiple arc-shaped grooves 10, which are concentrically arranged with the pin 2. The moving blade holder 3 has a hole, and the stud 11 can pass through the arc-shaped groove 10 and be fastened to the moving blade holder 3 by a nut.

[0022] When adjusting the blade angle, loosen the stud 11 and nut, and tighten them after adjustment. The shear blade 1 and the moving blade holder 3 are fastened together by multiple bolts, which reduces the force on the locking adjustment structure 6 during shearing and extends the service life of the mechanism.
