   Four side moulder comprises an upper template, a lower template, the upper template is provided with a stripping block, the stripping block is provided with a concave mold, and the concave mold peripheral has a ring die cutter, and the lower template is surrounded by a slide rail and a slider are disposed, the slide rail is provided with an oblique angle at the contact with the slider, a ram is disposed below the slider, and a punch cutter is disposed above the slider, A punch is arranged above the punch cutter.
   Through the rotary cutting process, Four side moulder are kept in the same plane, which is very flat; the burr direction is outward, and the size is controlled within 5% of the material thickness; the previous four steps are reduced to one process, reducing 75% of the manpower.
   In the industry, for the cylindrical or square tubular cutting process, in the past, multi-step cutting is used, that is, the engineering die is used to cut each edge separately. With this process, several sets of cutting die are required to be simultaneously produced. It is quite difficult for the four sections to remain flush on the same plane, and the direction of the trimming burrs is inward, which also greatly affects the assembly accuracy with other components.
   Four side moulder is a mold for bending a sheet workpiece into a predetermined shape on a bending machine. There are many kinds of bending dies, which are suitable for a variety of curved shapes. Even for the same curved shape, the bending dies are not the same. For the sake of bending efficiency and bending quality, Four side moulder for curved shape products are also constantly being improved.
   Four side moulder is formed by bending the upper and lower sides into the same structure as the left and right sides to form a structure surrounded by four sides; the forming precision of the corner can not be controlled by the ordinary mold for the bending process of the step, thereby causing the product structure The deformation is large and the quality is low; in the prior art, there is a mold which can solve the above problems caused by the ordinary mold.
   Before bending, the left and right ears hang down freely under the force of gravity. When the upper mold is moved down, since the outer edges of the left and right ears are flat with the outer edge of the upper mold body, the obstruction of the grooves on the left and right sides of the workpiece can be avoided. When the blades of the left and right ears contact the surface of the workpiece, Four side moulder body obliquely faces the left and right ears to apply a force in a direction of 45°, and in the horizontal direction, the left and right ears move outward, respectively, to restore the state, so that The blades protruding from the left and right ears move into the grooves on both sides of the workpiece.
