The invention discloses a U-shaped product external punching device. The U-shaped product external punching device comprises a lower die plate, an upper die plate, punching heads, second upper pressing blocks, second lower pressing blocks, sliding blocks and female dies, wherein the top surface of the lower die plate is connected with the second lower pressing blocks symmetrically; the two ends ofa workpiece are separately placed on the second lower pressing blocks; the second upper pressing blocks are detachably connected with the second lower pressing blocks; each sliding block is connectedto one side of the corresponding second lower pressing block; one end, close to the corresponding second lower pressing block, of each sliding block is connected with the corresponding female die; the female dies can be connected with the workpiece by sliding the sliding blocks; the upper die plate is positioned above the lower die plate; the punching heads are symmetrically connected to the bottom surface of the upper die plate; and the upper die plate moves downwards, and then the punching heads perform punching on the two ends of the workpiece. According to the U-shaped product external punching device, the sliding blocks are designed, therefore, the stability of fixing a U-shaped pipe is guaranteed, and the precision of subsequent punching is further guaranteed; and meanwhile, the punching heads at the two ends perform punching simultaneously, so that the accuracy of the positions of holes at the two ends of the U-shaped pipe is guaranteed, and the punching efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of molds, in particular to a U-shaped product outer punching device. Background technique [0002] It is difficult to punch holes at both ends of U-shaped tubular parts, and the hole precision is required to be high. In actual operation, there are two situations: (1) Flat material punching before forming. (2) Two punches are required after forming. In the first case, flat plate punching will lead to increased hole position error and poor stability after forming. The second case is time-consuming and laborious, and the work efficiency is low, and the two-time punching will increase the hole position error. Contents of the invention [0003] The object of the present invention is to provide a U-shaped product outer punching device to solve the above-mentioned defects or one of the defects in the prior art. [0004] In order to achieve the above object, the present invention is achieved by adopting the fo...
