Stamping parts processing plant said a lower pipe cutting tenon die

The stamping parts processing plant simply talk about the lower pipe cutting and tenon die. In the metal furniture industry, it is common to use rectangular pipes to form various specifications of the box. The cutting die retains the straight wall of the face, reducing welding and Polishing workload and beautify the appearance of the product; as shown in the figure; 1----lower die seat 2 guide post 3 stopper plate 4 guide sleeve 5 fixed plate 6 punch 7 work piece 8 rear edge 9 concave die stamping processing plant The Chinese square pipe cutting and tenoning die is designed according to the principle of sharp point breakthrough; it is mainly composed of a mold base with a guide post and a guide sleeve, a punch, a stop block and a concave mold; the concave mold is divided into upper and lower layers, and the upper layer has a side edge , Responsible for the separation of pipe side wall materials; the lower layer is responsible for the separation of pipe bottom plane materials; the angle of the inclined edge of the punch can be determined by the shear strength of the material. When the material is an aluminum square tube, in order to take care of the penetration ability of the sharp point, the bevel angle is 40°～45°. When the material is a square tube made of stainless steel or Q235, the strength should be taken care of, and the angle of the inclined blade is 45°-50°. Generally, the front straight wall of the pipe does not need to be cut in order to achieve the purpose of the beautiful appearance of the finished product; the upper plane of the pipe is actually cut by a part of the back slope after the sharp point of the punch penetrates into the workpiece; the rear straight wall is cut by the slope of the punch It forms an oblique cutting edge with the back side edge of the first-level die; the bottom plane of the pipe is separated by the flat edge of the punch and the second-level die; the stamping part processing plant should pay attention to the concave of the back side edge when designing the mold. The depth of the groove should be larger, as the waste storage space; when the stamping parts processing plant chooses the press, the ram stroke requirement is greater than 2.5 times the height of the pipe; recommended article: How to arrange the blanking sequence of the progressive die of the metal stamping part Article: Benchmark of the size of blanking parts in the processing of stamping parts
