Abstract

The invention discloses an electric shearing and expansion clamp. The electric shearing and expansion clamp consists of a shearing and expansion head, a hydraulic pump, a motor, a handle shell, a switch, an electric socket and a handle battery. The electric shearing and expansion clamp is an integrally hydraulic disassembling tool which is used for emergency rescuing operation of shearing and expansion, and is provided with a power supply, so the clamp is portable and convenient to operate.

Description

A kind of electronic cutting expanded pincers

Affiliated technical field

The present invention relates to the gripping tongs of a kind of shearing, expansion, the dual-purpose pliers of especially a kind of self-powered shearing, expansion.

Background technology

At present, known pliers function singleness is used pliers head easy abrasion for a long time, and the closure distance that produces jaw is inaccurate.For example number of patent application is 200620073506; Name is called and discloses the pliers that a kind of function that can realize traditional pliers can realize the wire stripping function again in the pliers; Comprise a pair of binding clip, a pair of pincers handle and be connected bearing pin; On a pincers handle, be set with a ledger-plate, on another pincers handle, be provided with a movable blades through alignment pin, an end of movable blades is movably arranged on through alignment pin and connects on the bearing pin; The size that on movable blades, also is provided with a circular arc gathering sill, can regulates the wire stripping cutting edge through this gathering sill; The bottom margin place of movable blades is provided with ratchet, is arranged on the ratchet of pincers on the handle and is used for the restraint blade and is rotated counterclockwise, and promptly plays the effect of locking wire stripping cutting edge.Number of patent application is 200720095007; Name is called a kind of electric tool pliers that is used for clamping, expand, cut off and discloses a kind of electric tool pliers of clamping, expand, cutting off of being used to, and it is characterized in that it is to be made up of housing, combined type multi-change speed mechanism, feed screw apparatus, electronic control part, stroke adjusting device, working head and cell apparatus; Its superiority is: 1. combined type multi-change speed mechanism can export low speed, big torsion.2. the radially commentaries on classics power of feed screw apparatus change motor is axial push-pull effort.3. electronic control part and stroke adjusting device are realized purposes such as clamping, expand, cut off, and can regulate electronic pincers in use cause jaw because of the binding clip wearing and tearing closure distance.4. the working head part can be changed according to user's needs voluntarily.Make its requirement of satisfying the user, realize multiple use (clamp, expand, cut off), easy to use, simple to operate.5. shell designs the ergonomic structure, and the handled easily person uses.And can distribute the heat that motor in use produces in good time, prolong the service life of motor.

Summary of the invention

In order to overcome existing pliers function singleness; The long-time pliers head easy abrasion of using; Produce the inaccurate deficiency of closure distance of jaw; The present invention provides a kind of electronic expansion pincers of cutting, and the self-powered expansion of this pliers, shearing gripping tongs tong arm and pincers sword adopt the self-powered expansion of novel high-strength alloy in lightweight material, shearing gripping tongs tong arm and pincers sword employing novel high-strength alloy in lightweight material to process.These gripping tongs start conveniently, use 12/24 volt of rechargeable battery, can under free position, use.

The technical solution adopted for the present invention to solve the technical problems is: this is electronic cuts and expands pincers and expand head, hydraulic pump, motor, handle casing, switch, electrical socket, handle battery and form by cutting.Motor is a permanent magnet direct current motor, and integrated hydraulic pump, cutting tool have electric liquid system of one's own in one, no longer needs extra engine-driven hydraulic pump or hydraulic hand-pump, also no longer needs hydraulic oil pipe certainly.But the steel plate of maximum shear ability 22mmQ235 round steel or 5mm can be done 360 degree rotations, is fit to the confined space, quick charge in 14 minutes, and a battery continues to use 40 minutes.The technical parameter of cutting head: normally cut off diameter Q235 round steel >=φ 20mm, Q235 sheet material >=3mm; Maximum is cut off diameter Q235 round steel >=φ 22mm, Q235 sheet material >=5mm; Maximum cutting opening 30mm; Maximum cutting force (at edge of a knife notch place) 325kN, maximum extension is apart from 150mm, maximum extension power 135kN.

The invention has the beneficial effects as follows integrated hydraulic break-in tool, the rescue operation that is used to shear Yu expands.Power autonomous, portable operation.

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Fig. 1 is a structural representation of the present invention.

1. cut the expansion head among the figure, 2. hydraulic pump, 3. motor, 4. handle casing, 5. switch, 6. electrical socket, 7. handle battery.

The specific embodiment

Check at first whether battery (7) is full of; Check then whether hydraulic oil (2) is filled it up with; Whether expansion head (1) is cut in inspection has damage (crackle) (incompleteness etc.), and the electronic expansion head (1) of cutting is carried out sky scissor test (switching), adjusts reversal valve at last; Clamp reinforcing bar or the steel plate that to shear and start trigger, carrying out operation.

Claims

1. electronic cutting expanded pincers, it is characterized in that: this is electronic cuts and expands pincers and expand head, hydraulic pump, motor, handle casing, switch, electrical socket, handle battery and form by cutting.

2. electronic cutting according to claim 1 expanded pincers, and it is characterized in that: motor is a permanent magnet direct current motor, and integrated hydraulic pump, cutting tool have electric liquid system of one's own in one, no longer needs extra engine-driven hydraulic pump or hydraulic hand-pump.

3. electronic cutting according to claim 1 expanded pincers, it is characterized in that: but the steel plate of maximum shear ability 22mmQ235 round steel or 5mm can be done 360 degree rotations, is fit to the confined space, quick charge in 14 minutes, a battery continues to use 40 minutes.

4. electronic cutting according to claim 1 expanded pincers; It is characterized in that: normally cut off diameter Q235 round steel >=φ 20mm, Q235 sheet material >=3mm; Maximum is cut off diameter Q235 round steel >=φ 22mm, Q235 sheet material >=5mm, maximum cutting opening 30mm, maximum cutting force (at edge of a knife notch place) 325kN; Maximum extension is apart from 150mm, maximum extension power 135kN.
