Split pressure film type wire crimper that electric power construction used
Technical Field
The invention relates to the technical field of wire crimper structures, in particular to a split film pressing type wire crimper for electric power construction.
Background
At present, cables and wire noses need to be crimped and combined in the power industry, and a large number of crimping wires are mainly manually operated, so that labor is wasted, and the working efficiency is low; in response to this situation, hydraulic crimping pliers have been developed.
With the development of the times, new technologies, new materials and new designs are continuously emerging, various manual hydraulic tools are widely applied, the manual hydraulic crimping pliers become one of indispensable tools in circuit engineering, in the power distribution process of wires and cables, residual redundant wires need to be cut off, then wire ends are crimped on copper noses, and the manual hydraulic pliers are connected to connecting columns and provided with automatic pressure relief devices, so that the manual hydraulic pliers are safe, reliable and light in self weight, the appearance of the connected wire ends is hexagonal, and the electric conductivity is good.
For example, patent No. cn201420794457.x discloses a crimping pliers suitable for cables of different specifications, which comprises a shell, a top cover, a piston, a gland and a grab bar, wherein the top cover and the piston are arranged at intervals up and down, the gland is connected with the shell through threads, the upper end of the gland is propped against the bottom of the piston, the top cover is arranged in a front-back through sliding groove arranged in the shell, and the top cover is combined with an elastic pin horizontally penetrating through the shell and extending into the top cover to realize front-back, up-down and left-right limiting; an upper die mounting screw hole and an upper die positioning hole are formed in the bottom of the top cover, the upper die positioning hole is arranged in the middle, and a lower die placing circular hole is formed in the middle of the top of the piston; be provided with first joint subassembly and second joint subassembly on the lateral wall of casing, hydraulic oil passes through first joint subassembly and pushes away the piston downstream in getting into the casing, and hydraulic oil passes through second joint subassembly and pushes away the piston upstream in getting into the casing. Simple structure, design benefit, install and remove the convenience, can satisfy the pressure equipment requirement of different diameter specification cables through changing upper and lower mould.
Present crimping pliers inserts through the bolt and keeps off fixedly to last press mold mostly, need take out the bolt earlier when clamping and getting unload cable and copper pipe, then take out the press mold and just can empty the upside space and operate, so substep flow, it is comparatively loaded down with trivial details inconvenience to use the operation, waste time, in addition because hydraulic pressure oil pipe is mostly leather matter, the rigidity has certain elasticity of bending, and then bend elastic top at hydraulic pressure oil pipe and drag base 1 and can take place about the skew, hand strength is limited to be difficult to just to, this can lead to the fact the problem of obstacle to the dress of getting of cable and copper pipe.
