Description

Shearing and pressing dual-purpose hydraulic pliers

Technical Field

The utility model relates to a hydraulic means field, concretely relates to cut and press dual-purpose hydraulic tong.

Background

When traditional hydraulic tong suppression terminal, to different cables, need to change different model size's mould, a instrument is joined in marriage many sets of moulds and is satisfied different operating mode requirements, does not possess the function of cuting in addition, perhaps needs customization shearing mould alone, and equipment manufacturing cost is high like this, and it is inconvenient to carry many sets of moulds, loses easily, and then the efficiency of construction is low, uses inconveniently, can not once accomplish simultaneously moreover and cut and the crimping.

SUMMERY OF THE UTILITY MODEL

In order to overcome the prior art not enough, the utility model provides a following scheme:

a shearing and pressing dual-purpose hydraulic clamp comprises: the hydraulic cylinder, the U-shaped cursor slide, the piston depression bar, cut the mould of pressing, the spacer pin, the piston depression bar with the hydraulic cylinder is sliding connection and coaxial line, U-shaped cursor slide and pneumatic cylinder formula casting structure as an organic whole, cut the mould of pressing and pass through sliding connection with the U-shaped cursor slide, the front end that the U-shaped cursor slide was inserted to the spacer pin.

Further, the hydraulic cylinder may be a manual hydraulic cylinder or an electric hydraulic cylinder.

Furthermore, a rectangular sliding groove is formed in the inner side of the U-shaped sliding arm and arranged along the axis direction of the piston pressing rod, a penetrating pin hole is formed in the front end of the U-shaped sliding arm, and a limiting pin is inserted into the pin hole.

Further, the shearing die comprises at least two shearing dies which are sequentially connected in series and slide into the rectangular sliding groove, the left side of each shearing die is limited by a piston compression bar, the right side of each shearing die is limited by a limiting pin, and each shearing die comprises a shearing die and a crimping die.

Furthermore, the front and back projection surfaces of the shearing and pressing die are square, the shearing die and the pressing die are respectively arranged on four sides of the square in the middle, the shearing die is in a cutting edge shape, and the pressing die is in a half regular hexagon shape.

The utility model has the advantages that: the utility model discloses utilize the hydraulic pressure principle, make hydraulic tong function more powerful, can be used for the shearing of reinforcing bar and cable, can also be used for binding post's suppression, one set of mould realizes two kinds of functions and can the crimping terminal of different models size, and is with low costs, and convenient to use saves construction cost and equipment cost, is fit for extensively applying in building engineering and electrical engineering.

Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:

as shown in the attached drawings, the shearing and pressing dual-purpose hydraulic pliers comprise: the hydraulic cylinder 1, the U-shaped sliding arm 2, the piston pressing rod 3, the shearing die 4 and the limiting pin 5, wherein the piston pressing rod 3 is connected with the hydraulic cylinder 1 in a sliding mode and is coaxial, the U-shaped sliding arm 2 and the hydraulic cylinder 1 are of an integrated casting structure, the shearing die 4 is connected with the U-shaped sliding arm 2 in a sliding mode, and the limiting pin 5 is inserted into the front end of the U-shaped sliding arm 2.

The hydraulic cylinder 1 may be a manual hydraulic cylinder or an electric hydraulic cylinder.

The inner side of the U-shaped slide arm 2 is provided with a rectangular sliding chute 21 which is arranged along the axial direction of the piston press rod 3, the front end of the U-shaped slide arm 2 is provided with a pin hole 22 which penetrates through, and a limit pin 5 is inserted into the pin hole 22.

The shearing die 4 comprises at least two dies which are sequentially connected in series and slide into the rectangular sliding groove 21, the left side is limited by the piston compression bar 3, the right side is limited by the limiting pin 5, and each shearing die 4 comprises a shearing die 41 and a crimping die 42.

The front and back projection surfaces of the shearing die 4 are square, the shearing die 41 and the crimping die 42 are respectively arranged on four sides of the square in the middle, the shearing die 41 is in a cutting edge shape, and the crimping die 42 is in a half regular hexagon shape.

The utility model discloses shear function's application method does, at first retract piston depression bar 3 into pneumatic cylinder 1 in, then extract spacer pin 5, slide into two shear compression moulds 4 in succession in the rectangle spout, two shear compression moulds 4 joint positions all are shear mould 41 when sliding into, see figure 1, insert spacer pin 5 this moment, then fill in two shear compression moulds 4 centre to waiting to cut the reinforcing bar, make pneumatic cylinder 1 promote piston depression bar 3 and drive the motion of first shear compression mould 4, the motion of second shear compression mould 4 under spacer pin 5's spacing, the reinforcing bar is cut at this moment.

The utility model discloses the application method of crimping function does, at first retract piston depression bar 3 in pneumatic cylinder 1, then extract spacer pin 5, take out press die 4, rotatory 90 degrees or 180 degrees, slide in two press die 4 toward rectangle spout in succession again, two press die 4 combination positions all are press die 42 when sliding in, notice two press die 42's half hexagon number should select unanimously, see figure 3, insert spacer pin 5 this moment, then fill in two press die 4 middles in treating the crimping terminal, make pneumatic cylinder 1 promote piston depression bar 3 and drive first press die 4 motion, second press die 4 can not move under spacer pin 5's spacing, the terminal is good by the crimping this moment.

It should be emphasized that those skilled in the art can make modifications, substitutions and alterations within the scope of the present invention, with reference to the above-described embodiments.
