Description

Technical Field

[0001] This utility model relates to a novel steel plate beveling and grinding device. Background Technology

[0002] In the steel processing industry, beveling of steel plates is a crucial step that directly affects the quality and efficiency of steel plate welding. Traditional methods of beveling steel plates mainly rely on manual hand-held grinding wheels, which has many problems and drawbacks.

[0003] First, traditional manual grinding methods are inefficient. Because grinding requires manual control of the grinding wheel, it is not only labor-intensive but also the grinding speed is limited by the worker's skill level, making it difficult to meet the demands of large-scale, high-efficiency steel plate processing. Second, the precision of manual grinding is difficult to guarantee. Due to human factors, it is difficult to maintain a consistent grinding depth and angle during the grinding process, resulting in low precision of the steel plate cut surface, which in turn affects the subsequent welding quality. Especially after gas cutting or plasma cutting, the steel plate cut surface often has an oxide layer and unevenness, further increasing the difficulty and complexity of grinding. Furthermore, traditional grinding equipment also has certain limitations in structure and function. For example, many grinding machines cannot flexibly adjust the grinding angle, making it difficult to adapt to the grinding needs of steel plate bevels at different angles. At the same time, the dust and noise generated by these machines during the grinding process also have a certain impact on the working environment and the health of the operators.

[0004] Chinese utility model patent CN 214922998 U, authorized on November 30, 2021, discloses a bevel grinding device for steel plate welding, including a magnetic slide rail. The magnetic slide rail includes a handle a, an electromagnetic base, a slide rail a, a mounting base, a slider a, a handle b, a slider b, and a slide rail b. The handle a and handle b are respectively installed at the head and tail ends of the electromagnetic base. The slide rail a and slide rail b are respectively installed on both sides of the upper surface of the electromagnetic base. The slider a and slider b, which are matched with the electromagnetic base, can slide freely along the axis of the guide rail on the slide rail a and slide rail b. When the electromagnetic base is energized, it generates a strong magnetic field to firmly adhere to the steel plate. The mounting base is connected and fixed to the upper surface of the slider a and slider b by bolts.

[0005] In use: The user places the entire device at the edge of the steel plate. By moving the electromagnetic base relative to the steel plate, the user ensures that the mobile grinder can grind the edge of the steel plate when it slides along the guide rail. In the initial starting position of the grinder, the grinding wheel is not in contact with the steel plate. Adjust the angle between the inclined surface of the variable angle base and the horizontal plane, and adjust the angle between the grinding wheel and the surface of the steel plate to the required angle so that the bevel angle meets the process requirements.

[0006] After adjusting the entire device to meet the above requirements, turn on the power to the electromagnetic base. Once the device is firmly attached to the steel plate, turn on the power to the grinder. The operator uses the push-pull handle to move the grinder as a whole. The grinding wheel contacts the edge of the steel plate, and the bevel of the steel plate edge is ground. The operator pushes and pulls the grinder back and forth along the guide rail axis to grind the bevel of the steel plate edge repeatedly. After completion, turn off all power to the device to complete the bevel grinding work of the steel plate.

[0007] When using this device, the relative position and angle must be adjusted first, then the power must be turned on so that the electromagnetic base can be attracted to the steel plate to be processed, then the bevel must be ground, and finally the power must be turned off. The operation is cumbersome and inefficient. Summary of the Invention

[0008] The technical problem to be solved by this utility model is how to overcome the above-mentioned defects of the prior art and provide a new type of steel plate beveling and grinding device.

[0009] To solve the above-mentioned technical problems, this novel steel plate beveling and grinding device includes a frame, a grinding wheel, and a motor that drives the grinding wheel. The frame includes an upper frame, four legs, and a backing plate. The upper frame is welded from four sections of angle steel. Each section of angle steel consists of vertical bars and inner bars connected to the inner side of the lower edge of the vertical bars. The tops of the four legs are welded to the four corners of the upper frame. The motor is fixed in the middle of the frame, and the output shaft of the motor is vertically upward. The grinding wheel is fixed on the output shaft. The left and right vertical bars of the upper frame have corresponding notches, which are lower than the upper surface of the grinding wheel. The upper edge of the backing plate is inclined outward, and its lower edge presses against the two notches. Diagonal bracing arms are fixed on its outer side, and the lower parts of the two diagonal bracing arms are fixed to the upper frame. With this design, when using the equipment, first start the motor, then hold the steel plate to be processed and place one side against the backing plate with its lower edge in contact with the upper surface of the grinding wheel. Use the high-speed rotating grinding wheel to bevel the steel plate. After processing one steel plate, you can pick up the next steel plate for beveling, which is convenient and efficient.

[0010] As an optimization, a reinforcing short rod is connected between the lower parts of adjacent outriggers. The motor is a variable frequency motor and equipped with a speed controller. This design results in a robust frame structure and convenient motor speed adjustment.

[0011] As an optimization, the diagonal brace has a long slotted through hole, and the adjacent vertical steel bars of the upper frame have corresponding through holes. Both the long slotted through holes and the long slotted through holes are fitted with fastening bolts or screws to secure the backing plate. This design facilitates fixation, and allows for the replacement of backing plates with different tilt angles if necessary.

[0012] As an optimization, lifting roller platforms are provided on both the left and right sides of the frame. These platforms have multiple parallel rollers fixed to a hydraulic lifting support. This design allows for easier and more convenient processing of long and heavy steel plates by placing the lifting roller platforms on both sides.

[0013] This novel steel plate beveling and grinding device has a simple structure, is easy to use, and has high processing efficiency, making it suitable for grinding steel plate bevels. Attached Figure Description
