Description

Technical Field

[0001] The utility model relates to a metal sheet processing device, in particular to a shearing and bending device. Background Art

[0002] A shearing and bending machine is a device that combines shearing and bending functions and is widely used in sheet metal processing, automotive manufacturing, and home appliance manufacturing. The machine primarily consists of a main body, a shearing mechanism, a bending mechanism, and a drive mechanism. The shearing mechanism is used to cut sheet metal to a predetermined length, while the bending mechanism is responsible for precisely bending the sheared sheet metal. To ensure the stability of the sheet metal during the shearing and bending processes, the machine is typically equipped with a pressure plate to hold the sheet metal down and prevent it from shifting or tilting during processing. However, current shearing and bending machines have design limitations, particularly regarding the movement direction and placement of the shearing and bending mechanisms. Typically, both mechanisms move from top to bottom. While this design effectively performs the basic shearing and bending functions, it also introduces some inconveniences. First, the top-down movement of the shearing and bending mechanisms requires them to occupy a relatively high position within the machine, complicating their placement. To prevent interference between the two mechanisms during movement, additional space is often required within the machine. This not only increases the difficulty of design and manufacturing, but also increases the size of the overall equipment, resulting in more factory space being occupied and increasing the installation and use costs of the equipment. Secondly, due to the high position of the shearing and bending mechanisms, the equipment may have a high center of gravity during operation. Equipment with a high center of gravity is prone to vibration when running at high speeds, affecting processing accuracy and potentially adversely affecting the long-term stability and service life of the equipment. In addition, due to the larger overall structure, the maintenance and operation of the equipment also become more complicated, increasing the operator's work difficulty and the equipment maintenance cost.

[0031] The lower frame 12 includes a base plate 121 and a receiving component 122 fixedly connected to the upper side surface of the base plate 121. The receiving component 122 includes two receiving blocks 1221 arranged at intervals along the length direction of the sheet material 10. The upper end surfaces of the two receiving blocks 1221 define a receiving surface 1222. A movable space 1223 is formed between the two receiving blocks 1221. The bending mechanism 3 can move up and down in the movable space 1223.

[0032] The connecting frame 13 includes four guide posts 131 and four fixed frame plates 132. The four guide posts 131 are positioned at the four corners of the rectangular frame, and the four fixed frame plates 132 are positioned at the four corners of the rectangular frame. In this embodiment, the four guide posts 131 are cylindrical, and a rack structure 1311 is formed on the inward side of each guide post 131. The two ends of the guide posts 131 are fixedly connected to the upper frame 11 and the bottom plate 121, respectively. The two ends of the fixed frame plates 132 are fixedly connected to the upper frame 11 and the bottom plate 121, respectively.

[0033] The sheet material 10 is continuously extended, and one side of the sheet material 10 is bent toward the other side to form a groove 102 (i.e., a cuff structure). Notches 101 are punched at intervals along the length direction on both sides of the sheet material 10, and a shear bending area is formed between the notches 101 on both sides.

[0034] The receiving surface 1222 is used to receive the sheet material 10; the shearing mechanism 2 is used to shear the sheet material 10, the pressing plate mechanism 4 is used to press the sheet material 10 against the receiving surface 1222, and the bending mechanism 3 is used to bend the shearing portion of the sheet material 10; the pressing plate mechanism 4 includes two pressing plates, the pressing plate includes a pressing plate body 41 and a sliding pressing plate 42 provided on the pressing plate body 41, the pressing plate body 41 includes a slide rail 411, and the sliding pressing plate 42 is slidably connected to the slide rail 411 ; The sliding pressure plate 42 includes an initial position drooping relative to the pressure plate body 41 and a working position flush with the pressure plate body 41; when in the initial position, the pressure plate body 41 is close to the sheet material 10 so as to drive the sliding pressure plate 42 to move to abut the sheet material 10, and the pressure plate body 41 can move to press against the sheet material 10, so as to drive the sliding pressure plate 42 to slide relative to the sheet material 10 through the slide rail 411 until it extends into the groove 102, and the sliding pressure plate 42 can move to the working position.

[0035] During actual operation, the shearing mechanism 2 moves downward on the upper frame 11 to shear the sheet material 10 at the shearing and bending area of the sheet material 10. The pressing plate mechanism 4 moves downward, and the sliding pressing plate 42 first presses against other areas of the sheet material 10. As the pressing plate body 41 continues to move downward, the sliding pressing plate 42 slides relative to the sheet material 10 until the sliding pressing plate 42 presses against the lower side of the groove 102 and the sliding pressing plate 42 is flush with the pressing plate body 41. At this time, the entire sheet material 10 is pressed along its own width direction. The bending mechanism 3 moves upward to bend the sheet material 10 in the shearing and bending area upward, which can avoid problems such as the bending line at the cuff structure being not straight and the sheet material 10 being deformed.

The pressure plate body 41 includes a slide groove 412, and the sliding connection block 421 includes a slider 4211. The slider 4211 slides on the slide groove 412. The two side walls of the slide groove 412 form the slide rails 411. In this embodiment, the angle between the slide rails 411 and the slide groove 412 relative to the receiving surface 1222 is 45 degrees.
