Embodiment Construction
[0028] The bending method of using high-strength steel plate to produce the special-shaped part of the U-shaped bucket dump truck body side plate 1 is: first make a set of upper and lower molds, the special upper mold includes (see Picture 8 ) There are a die head 7 and a die handle 2. The die handle 2 and the die head 7 are connected through a connecting seat 3. A number of threaded adjusting screw rods 4 are installed on the connecting seat 3. The front end of the screw rod is equipped with a roller seat 6 and a roller seat 6. There is a row of five rollers 5 installed on the upper part; the special lower mold (see Picture 12 1) It has a mold base 9 with a bending "V" groove 8 on the upper surface of the mold base 9; install the upper and lower molds above on the CNC bending machine; then perform the bending process as follows:
[0029] The first step: take the high-strength steel plate and cut the material according to the product design size;
[0030] Step 2: Determine the fir...

Abstract
The invention discloses a bending method for producing a special-shaped part of a bucket side plate of a U-shaped bucket dumper by using a high-strength steel plate. According to the bending method, a board is bent, processed and formed for three times by adopting specially-produced upper die and lower die, wherein the specially-produced upper die comprises a die head and a die shank; the die shank and the die head are connected by a connecting seat; a plurality of thread adjusting lead screws are arranged on the connecting seat; roller seats are arranged at the front ends of the lead screws; a plurality of rollers are arranged on the roller seats; the specially-produced lower die is provided with a die holder; and a bent V-shaped groove is formed in the upper surface of the die holder. The bending method comprises the following steps of mounting the upper die and the lower die on a numerical control bender; and then discharging, determining three bending parts, bending at the first part, bending at the third part, bending at the second part, demolding and forming. According to the bending method disclosed by the invention, the problems of high welding, splicing and processing cost, complex process, low production efficiency and the like of the bucket side plate of an existing U-shaped bucket dumper are solved; and the bending method is mainly used for bending, forming and processing the bucket side plate of the U-shaped bucket dumper.
Description
Technical field [0001] The invention relates to the processing technology of mechanical parts, in particular to a method for bending high-strength steel plates to produce special-shaped parts of U-shaped bucket dump truck body side plates. Background technique [0002] 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 is a long straight tail plate. One of the existing processing techniques for the side plate of the car body is to bend into two parts, see figure 2 , [0003] Then the tailor welding is completed. The disadvantages are: complicated process, low production efficiency, high welding cost, high technical operation requirements, affecting product qualification rate, and overall unsightly. For this kind of closed frame structure, there is also the second production method, which is to first bend into a certain shape of the opening part (such as image 3 ), and then press several ...
