Detailed Description
Referring to fig. 1-3, the shaping mechanism of the present invention comprises an upper connecting plate 1, a lower connecting plate 2, an oil cylinder 4, a shaping block 5 and a shaping plate 3. The template is connected with a bending device. The rear ends (the right ends shown in figures 1 and 2) of the upper connecting plate and the lower connecting plate are respectively hinged with the upper side and the lower side of the oil cylinder; the front ends of the upper connecting plate and the lower connecting plate are hinged with the shaping plate. The oil cylinder, the upper connecting plate, the lower connecting plate and the template form a closed loop, and the structure can balance the interaction force in the bending process. The piston rod of the oil cylinder is fixedly connected with an oil cylinder connecting block 9, and the oil cylinder connecting block is hinged with the shaping block 5 through a pin shaft 10. The piston rod of the oil cylinder moves in a telescopic way to drive the shaping block to move linearly. In order to ensure the running stability of the piston rod of the oil cylinder, two guide sleeve fixing blocks 8 are symmetrically fixed at the rear ends of the upper connecting plate and the lower connecting plate, a guide sleeve 7 is arranged on each guide sleeve fixing block, two guide pillars 6 are symmetrically fixed on the oil cylinder connecting block, and each guide pillar is respectively matched with the guide sleeve in a sliding manner.
Referring to fig. 3 and 4, the shaping plate and the shaping block used in the operation of the apparatus are determined according to the shape of the product pieces. As shown in fig. 4, the product piece 11 has a symmetrical structure, the middle of the product piece is a first arc segment 11-1 with a larger radius, the outer side of the first arc segment is a straight segment 11-2, and the outer side of the straight segment is a second arc segment 11-3 with a smaller radius. When the product part is bent, the template is provided with a template first arc section 3-1, a template straight section 3-2 and a template second arc section 3-3. Wherein the first arc section of template matches with the first arc section of product spare, the straight section of template matches with the straight-line segment of product spare, template second arc section matches with the second arc section of product spare. The length of the working face of the shaping block is matched with the length of the straight section of the shaping block. During bending, the shaping plate is gradually attached to a product from the end to the middle along with the rotation process of the bending equipment, and is bent and formed, when the product is bent to the straight line section of the product, the oil cylinder acts to drive the shaping block to be vertically pressed on the straight line section of the product, so that the straight line section of the product is prevented from being bent; and after the shaping block presses the product piece, the shaping plate rotates to continuously attach to the product, and the bending of the subsequent arc section of the product piece is completed.
