Description

Technical Field

[0001] This utility model relates to the field of cover plate bending technology, specifically to a one-time forming bending mold for excavator boom U-shaped cover plates. Background Technology

[0002] Currently, in the traditional production process of U-shaped excavator boom covers, a gooseneck mold is typically used for two positioning and two bending processes. The multiple positioning and bending processes are not only time-consuming and labor-intensive, but also lead to the accumulation of errors due to manual operation, resulting in inconsistent product dimensions. Furthermore, repeated processing can cause scratches or deformation on the workpiece surface, affecting product quality.

[0003] In existing technologies, although there are attempts to simplify the process and achieve one-time bending by adding additional positioning devices, the additional positioning devices need to be repositioned every time the mold is changed and clamped, which still has problems such as complicated operation, difficulty in precision control, high cost, and low efficiency, and cannot fully meet the needs of modern manufacturing industry for efficient and high-quality production.

[0029] A hydraulic press 14 is provided at the bottom of the top plate 3. An upper template 15 is fixedly connected to the output end of the bottom of the hydraulic press 14. A mold handle 16 is vertically provided at the bottom of the upper template 15. An upper mold head 17 is provided at the bottom of the mold handle 16. A bending blade 18 is symmetrically provided at the bottom of the upper mold head 17.

[0030] The first positioning plate 8 is fixedly snapped into one end of the U-shaped groove 6. The first positioning plate 8 has a first positioning groove 19 on its inner side, which is used to snap into the head of the U-shaped cover plate 10 of the bucket rod. The second positioning plate 9 is symmetrically arranged at the other end of the lower mold base 5, which is used to snap into the tail of the U-shaped cover plate 10 of the bucket rod.

[0031] The top of the base 11 is an inwardly concave arc shape, and the outer side of the top of the base 11 protrudes upward. Several grooves 20 are evenly provided on the protruding part, and the bottom of the grooves 20 are connected to one end of the spring 13.

[0032] The bottom of the flap 12 is an outwardly convex arc shape, and the top is an inwardly concave arc shape. The bottom of the flap 12 is fitted and connected to the top of the base 11.
