Description

TECHNICAL FIELD

[0001] The application belongs to the field of aluminum busbar shearing, and particularly relates to a V-shaped shearing bed for aluminum busbar. BACKGROUND

[0002] Aluminum busbar has a wide range of applications, such as high and low voltage switch cabinets, substations, bus ducts, electrical switches, etc. Different application scenarios have different requirements for the size, shape and performance of aluminum busbar. Through shearing, aluminum busbar that meets the requirements can be customized according to specific application needs to meet the electrical connection needs in different scenarios. Aluminum busbar usually needs to be sized according to the requirements of specific electrical equipment and systems. Through shearing, aluminum busbar can be cut to the required length and cross-sectional size to ensure that it can be perfectly fitted into the equipment or system to meet the needs of electrical connection and transmission.

[0003] The shearing blades of the existing aluminum busbar shearing bed are flat blades. When shearing cylindrical aluminum busbar, the aluminum busbar needs to be ground and processed to make it softer before being placed in the shearing bed for shearing. Otherwise, deformation of the aluminum busbar and increased wear of the aluminum busbar are likely to occur during shearing with flat blades. During shearing, flat blades do not match the shape of the cylinder, so more force is required and the shearing time is prolonged, and the process of shearing aluminum busbar is increased, resulting in reduced shearing efficiency. SUMMARY

[0004] The present application aims to provide a V-shaped shearing bed for aluminum busbar to solve the problem of reduced shearing efficiency caused by the use of flat blades in the existing shearing of aluminum busbar, which increases the shearing process and the force used for aluminum busbar, and prolongs the shearing time.

[0005] The V-shaped shearing bed for aluminum busbar in the present application comprises a placement groove and a tool holder. The tool holder is inverted "concave" shaped. The tool holder is located in the middle of the placement groove. The inner top of the tool holder is slidingly connected with a blade. The blade is fixedly connected with a driver that drives it to rise and fall. The cutting edge of the blade faces the placement groove, and the side facing the placement groove is inverted "V" shaped. Both sides of the placement groove are provided with sliding rails that extend from one end of the placement groove to the other end. The sliding rails are slidingly connected with a plurality of clamping mechanisms. The clamping mechanisms are each provided with a driver that drives it to slide. The clamping mechanisms on both sides correspond to each other, and the clamping mechanisms on both sides are symmetrically arranged.

[0006] The working principle of the present scheme is: when in use, place the aluminum busbar to be cut on the placing groove, use the clamping mechanism on both sides to clamp the aluminum busbar, after the clamping mechanism clamps the aluminum busbar, start the driver of the clamping mechanism to drive the aluminum busbar to slide downward below the tool holder, until the middle part of the aluminum busbar enters below the blade, while the clamping mechanism is distributed at both ends of the tool holder, after determining the length of the aluminum busbar to be cut, the driver of the blade can be started to drive the blade to descend downward, so that the blade shears the aluminum busbar;

[0007] Beneficial effects: 1. High cutting efficiency: the inverted V-shaped blade design helps to cut into the aluminum busbar from both sides more quickly, especially when continuous or large-scale cutting is performed, which can significantly improve production efficiency;

[0008] 2. Good cutting quality: the inverted V-shaped blade shape can produce smooth and uniform cutting surfaces when cutting into the aluminum busbar from both sides, reducing burrs and tearing phenomena, thereby ensuring better appearance quality and dimensional accuracy of the cut aluminum busbar;

[0009] 3. Strong adaptability: the inverted V-shaped blade can be used for cutting cylindrical aluminum busbars of different diameters and thicknesses, and by adjusting cutting parameters such as cutting speed and feed amount, it can adapt to different cutting requirements;

[0010] 4. Process saving: the inverted V-shaped blade can effectively increase the shearing force during shearing, reducing the pre-process of aluminum busbar shearing and speeding up the shearing efficiency.

[0011] Further, both sides of the blade are provided with polishing mechanisms for polishing the cut aluminum busbar, and the two polishing mechanisms are symmetrically arranged. After the blade shears the aluminum busbar, the driving clamping device is driven to move away from the cut aluminum busbar slightly away from both sides of the blade, and then the polishing mechanisms can be driven to polish the ends of the cut aluminum busbar to remove burrs.

[0012] Further, a descending channel for accommodating the blade and polishing mechanism is formed in the middle of the placing groove. The channel increases the space for the descent of the blade and polishing mechanism, facilitating the cutting of the aluminum busbar.

[0013] Further, the polishing mechanism comprises a polishing piece and a lifting seat, the lifting seat is slidingly connected to the side wall of the blade, a recess is formed in the side of the lifting seat close to the blade, a stop block is fixedly connected to the side wall of the blade and slidingly connected in the recess, the polishing piece is rotatably connected to the side of the lifting seat away from the blade and fixedly connected with a motor driving it to rotate. When the blade descends, the stop block descends in the recess until it moves to the lowermost part of the recess, which drives the lifting seat to move downward, and at the same time the motor of the polishing piece starts to drive the polishing piece to rotate. After shearing is completed, the rotating polishing piece is moved to the end of the aluminum busbar to polish the burrs and flash at the shearing part.

[0014] Further, the clamping mechanism comprises a slider, a column and an arc-shaped pad, the slider is slidingly connected to the slide rail, the column is vertically fixedly connected to the upper side of the slider, the top end of the column is fixedly connected with a gas cylinder, the arc-shaped pad is fixedly connected to the telescopic end of the gas cylinder, and the telescopic end of the gas cylinder points to the placing groove. When the aluminum bus is placed in the placing groove, the gas cylinder can drive the arc-shaped pad to move to the outside of the aluminum bus, so as to clamp the aluminum bus from both sides, and the slider can drive the arc-shaped pad to move to any position of the slide rail, so as to clamp the aluminum bus from this position, and facilitate the movement of the cut aluminum bus.

[0015] Further, the side of the arc-shaped pad facing the placing groove is fixedly connected with a rubber pad. The rubber pad can increase the friction between the arc-shaped pad and the aluminum bus when the arc-shaped pad clamps the aluminum bus, so as to facilitate the movement of the aluminum bus.
