Abstract

The invention relates to a forming device for a U-shaped lazy arm of a crane. The forming device comprises a first gantry frame and a second gantry frame which are parallelly arranged and further comprises a main beam arranged between the first gantry frame and the second gantry frame and used for connecting the first gantry frame with the second gantry frame, a lifting U-shaped upper mold is arranged on the main beam, and a U-shaped lower mold matched with the U-shaped upper mold to form the U-shaped lazy arm is arranged below the U-shaped upper mold. The U-shaped lower mold is arranged on arear bracket located on the same side of the first gantry frame and the second gantry frame, and a front bracket is arranged on the other side of the first gantry frame and the second gantry frame. Aplate feeding device horizontally moving in the length direction of the first gantry frame or the second gantry frame is arranged on the front bracket, a to-be-formed plate is completely pressed intothe U-shaped lower mold through the lifting U-shaped upper mold, one-time forming of the U-shaped lazy arm is completed, and the forming device is simple and reliable in structure, convenient to operate, and high in forming quality.

Description

technical field [0001] The invention belongs to a production and manufacturing equipment, in particular to a forming device for a U-shaped boom of a crane. Background technique [0002] At present, the boom production systems of small and medium-sized crane manufacturers all use ordinary folding machines or numerically controlled folding machines to complete the forming of U-shaped booms through dozens of approximate fitting methods. Its operation is complicated, the operation requirement is high, the equipment requirement is high, and the manufacturing cost is relatively high. In addition, the existing production method requires a large number of auxiliary workers in actual work, such as manual intervention and control, and the work efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a crane U-shaped boom forming device with high working efficiency, low labor intensity, avoiding hidden dangers ca...
