Abstract
The bending method of high-strength steel plate to produce special-shaped parts of U-shaped bucket dump truck bucket side plate; it uses a special upper and lower die to bend the sheet material three times. The special upper die includes a die head and The mold handle, the mold handle and the die head are connected through a connecting seat, and several threaded adjustment screw screws are installed on the connecting seat. The front end of the screw screw is equipped with a roller seat, and several roller seats are installed on the roller seat; the special lower mold has a mold The upper surface of the mold base is made with a bending "V" groove; install the above upper and lower molds on the CNC bending machine; then cut the material → determine the three bending points → the first bending → the third First bending → second bending → demoulding; the present invention solves the problems of high welding and assembling processing cost, complicated process and low production efficiency of the side plates of the U-shaped bucket dump truck, and is mainly used for U-shaped bucket dump trucks. Bending and forming processing of bucket side plate of bucket dump truck.
Description
technical field [0001] The invention relates to the processing technology of mechanical parts, in particular to a bending method for producing U-shaped bucket dump truck bucket side plate special-shaped parts from high-strength steel plates. Background technique [0002] For the structure of the side plate of the U-shaped bucket dump truck, see figure 1 , the front end is a closed quadrilateral structure, and the rear part is a long straight tail plate. One of the existing technical methods for processing the side plate of the car body is to bend it into two parts, see figure 2 , [0003] Then tailor welding is completed, but its disadvantages are: complex process, low production efficiency, high welding cost, high technical operation requirements, affecting product qualification rate, and overall unsightly appearance. For this type of closed frame structure, there is also the production method of method 2, which is to bend an opening part of a certain shape (such as im...
