[0051] Such as figure 1 , figure 2 and image 3 As shown, a U-shaped workpiece bending mold includes an upper mold and a lower mold, the upper mold includes an upper mold clamping part 1, an upper mold body 2 and an upper mold cutter head 3, and the lower mold includes a lower mold base 4 and a lower mold Forming block 5; the upper mold cutter head 3 is connected with the upper mold body 2 by two bolts, the bottom surface of the upper mold cutter head 3 is U-shaped; the upper surface of the lower mold base 4 is provided with grooves; the lower mold forming block 5 The number is two, which are respectively symmetrically installed on both sides of the groove on the upper surface of the lower mold base 4; an adjustment pad 6 is also provided between the inner wall of the groove and the lower mold forming block 5, and the number of the adjustment pad 6 is 10. Two, including two with a thickness of 5mm, two with a thickness of 6mm, two with a thickness of 7mm, two with a thickne...
Embodiment 2
[0069] A U-shaped workpiece bending die in this implementation is the same as that in Embodiment 1, the difference is that the number of adjusting pads 6 is 2, and the thicknesses are 15mm and 9mm respectively.
[0070] The using method of a kind of U-shaped workpiece bending die in the present embodiment is the same as embodiment 1, the difference is,
[0071] Step B. The radius of the arc end of the U-shaped workpiece to be processed is 63mm, and the distance between the lower mold forming blocks 5 is 150mm when the adjusting pad 6 is not installed, then by selecting a thickness of 9mm and a thickness of 15mm to adjust Spacer 6 is used to adjust the distance between the two lower molding blocks 5 to be 126mm;
[0072] Step D. Install the upper mold, select the upper mold cutter head 3 with a U-shaped bottom surface radius of 63 mm, fasten it to the upper mold body 2 with bolts, and fix the upper mold clamping part 1 on the upper mold of the bending machine in the clamping d...
Embodiment 3
[0081] A U-shaped workpiece bending die in this implementation is the same as that in Embodiment 1, the difference is that the number of adjusting pads 6 is 6, and the thickness is 15mm.
[0082] The using method of a kind of U-shaped workpiece bending die in the present embodiment is the same as embodiment 1, the difference is,
[0083] Step B. The radius of the arc end of the U-shaped workpiece to be processed is 45mm, and the distance between the lower mold forming blocks 5 is 150mm when the adjusting cushion block 6 is not installed, and the two are adjusted by installing four 15mm adjusting cushion blocks 6 The distance between each lower molding block 5 is 90mm;
[0084] Step D. Install the upper mold, select the upper mold cutter head 3 with a U-shaped bottom surface radius of 45 mm, fasten it to the upper mold body 2 with bolts, and fix the upper mold clamping part 1 on the upper mold of the bending machine in the clamping device.

Abstract
The invention discloses a U-shaped workpiece bending die, use of the U-shaped workpiece bending die and a manufacturing method of an upper die cutting head, and belongs to the field of bending machines. By means of the U-shaped workpiece bending die, use of the U-shaped workpiece bending die and the manufacturing method of the upper die cutting head, the problem that an existing bending die cannot produce U-shaped workpieces of different circular arc end radiuses in a high-speed and high-quality mode is solved. The U-shaped workpiece bending die comprises an upper die and a lower die. The upper die comprises an upper die clamping portion, an upper die body and the upper die cutting head. The lower die comprises a lower die base and lower die forming blocks. The upper die cutting head is connected with the upper die body through bolts. The upper surface of the lower die base is provided with a groove, and the two lower die forming blocks are symmetrically arranged on the two sides of the groove in the upper surface of the lower die base respectively. Adjusting cushion blocks are further arranged between the inner wall of the groove and the lower die forming blocks. The inner sides of the upper surfaces of all the lower die forming blocks are provided with circular arc grooves, and all the circular arc grooves are internally provided with workpiece power-assisting columns. The U-shaped workpiece bending die is safe, reliable, suitable for producing the U-shaped workpieces of different circular arc end radiuses and high in production speed and product quality.
Description
technical field [0001] The invention belongs to the field of bending machines, and in particular relates to a method for using a U-shaped workpiece bending die. Background technique [0002] The U-shaped workpiece is one of the workpieces that are often bent and processed by the bending machine. Because the radius of the arc end of various U-shaped workpieces is different, the demand is large, and the quality requirements are getting higher and higher, which has brought a lot to the processing and production. In order to relieve production pressure and keep up with the pace of production, there is an urgent need for a U-shaped workpiece processing method that can quickly, safely and high-quality produce U-shaped workpieces with different radii. [0003] Chinese Patent No. 201220055907.4, a patent document with a publication date of September 19, 2012, discloses a lower die of a bending machine with an adjustable opening, which belongs to the field of bending machine dies.
