Embodiment Construction

[0015] The present invention is made up of upper formwork 1, lower formwork 2, punch 3, die 4, positioning plate 5, rib plate 8, bolt 10, cylindrical pin 11.

[0016] image 3 It is shown that both sides of the liner 12 are bent respectively, the left side is bent at an obtuse angle with an angle of 116°, and the right side is bent at an acute angle with an angle of 64°.

[0017] figure 1 It is shown that the upper template 1, the punch 3 and the rib plate 8 form the punch assembly. The upper template 1 is connected under the punch of the stamping equipment, the punch 3 is fixedly connected to the lower surface of the upper template 1, and the rib plate 8 is connected to the upper part of the upper template 1 and the punch 3, so that the upper template 1 and the punch 3 are firmly connected .

[0018] figure 1 It is shown that the lower template 2 is fixedly connected on the workbench of the stamping equipment, the die 4 is located on the upper surface of the lower templat...

Abstract

The invention relates to a stamping die for a left bent seat lining board of a bulldozer, and belongs to the technical field of stamping dies. The stamping die for the left bent seat lining board of the bulldozer is used for conducting press forming on the left bent seat lining board of the bulldozer. According to the technical scheme, an upper die plate is connected below a punching head of stamping equipment, a convex die is fixedly connected with the lower surface of the upper die plate, and a lower die plate is fixedly connected to a workbench of the stamping equipment; a concave die is fixedly connected with the lower die plate through a bolt, the lower end of the convex die corresponds to one molding groove of the concave die in a matching mode, and a positioning plate is fixed to the upper surface of the concave die through a bolt. According to the stamping die for the left bent seat lining board of the bulldozer, the stamping equipment is used for molding bends at the two ends of the lining board, the concave die is provided with two molding grooves which are matched with the bent angles at the two ends of the lining board respectively, and thus molding is conducted on the bends at the two ends of the lining board through the two molding grooves; positioning can be conducted on a lining board plate material through the positioning plate, so that the molding position is accurate. The stamping die for the left bent seat lining board of the bulldozer is simple in structure, convenient to use, accurate in bent angle and high in stamping speed; not only is the quality of the lining board ensured, but also the production efficiency is improved greatly; the needs of the production can be met.

Description

technical field [0001] The invention relates to a mold for stamping and forming the lining plate of a left curved seat of a bulldozer, which belongs to the technical field of stamping molds. Background technique [0002] There is a lining plate in the left bending seat of the left and right bending plate assembly of SD7 high-drive bulldozer. The material of the lining plate is Q235C and the thickness is 8mm. The lining plate is welded on the inside of the left bending plate. Comes with connection sleeve. There are bends on both sides of the liner, the left bend is an obtuse angle with an angle of 116°, and the right bend is an acute angle with an angle of 64°. At present, the equipment used for bending the lining board is a bending machine. The bending machine does not have special tools for bending the angles on both sides of the lining board, and it is difficult to ensure the accuracy of the angle. Poor, can not meet the needs of production, need to be resolved. Conten...
