Abstract

The invention discloses a split hydraulic clamp. A clamp upper cover and a clamp positioning spring pin are inserted into a clamp upper cover positioning hole, an upper die and clamp upper cover positioning hole is formed on an upper die, an upper die and clamp upper cover positioning spring pin is inserted into the upper die and clamp upper cover positioning hole, the upper die is inserted into the clamp upper cover, and an upper die pressing step butts against a clamp upper cover support step; a piston anti-rotation bulge is formed on a clamp body and is clamped in a piston anti-rotation groove; a lower die positioning pin presses a compression spring and is arranged in a lower die positioning pin installation hole, a notch is formed on the lower die positioning pin, and a handle extends into the notch; and a piston and lower die positioning hole and a lower die step are formed on a lower die, a piston pressing step is formed on the upper part of a lower die inserting groove, and the lower die step butts and presses against the lower part of the piston pressing step. The split hydraulic clamp has a simple structure, light weight and high bearing capacity and is low in production cost and easy to operate.

Description

technical field

[0001] The invention relates to the technical field of hydraulic pliers, in particular to a kind of intermediate connecting pipe, tension clamp and equipment clamp suitable for overhead steel-cored aluminum stranded wire and steel stranded wire, and for crimping copper-aluminum with large cross-section Hydraulic pliers for cables. Background technique

[0002] like figure 1 , 2 As shown, the existing BYO-300T split hydraulic tongs are composed of a caliper body A1, a tongs upper cover A2, a piston A5, an upper mold bracket A3, a lower mold bracket A4, an upper mold and a lower mold, and it has the following deficiencies:

[0003] 1. A square guide post A21 is formed on the upper cover A2 of the pliers, and the square guide post A21 is inserted into the linear square guide groove A11 on the pliers body A1, so that when crimping, the square guide post A21 and the square guide groove A11 are about The shaking gap is large, causing large crimping errors. Dur...
