Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides an embodiment:

the utility model provides an accurate electric jar steel pipe ejection bender, includes electric jar 1, and electric jar 1 can avoid appearing the oil leak like the pneumatic cylinder and lead to the condition emergence of unable use, is equipped with fixed subassembly 2 on electric push rod of electric jar 1, and fixed subassembly 2 comprises lug 21 and concave block 22, and the hole cover that lug 21 and concave block 22 seted up on through lug 21 and concave block 22 is established on electric push rod of electric jar 1.

Further, as shown in fig. 4-5, the protruding block 21 and the concave block 22 are in a concave-convex type engaging connection state, and the protruding block 21 and the concave block 22 are in a cubic structure when they are engaged with each other, and the connection structure enables the protruding block 21 and the concave block 22 to be quickly assembled on the electric push rod of the electric cylinder 1 or quickly separated from the protruding block 21 and the concave block 22.

The bottom of concave block 22 is rotated through the connecting axle and is connected with base 3, and base 3 is circular structure, and the focus of device is in base 3's center department to also reduced area when making this device more stable, rotate the connecting axle of being connected through lug 21 bottom and base 3 and can carry out three hundred sixty degrees rotations, if the steel pipe locating place differs, can directly rotate this device, reduced the time that constructor carried the steel pipe.

Electric cylinder 1's output fixed mounting has centre form 4, and centre form 4 is the arc structure, and lug 21's surface bottom fixedly connected with connection panel 5, connection panel 5 are the fixed surface of level form and lug 21 through the welded mode and are connected, and connection panel 5 is fan-shaped structure, and connection panel 5 keeps away from the one end fixedly connected with external mold 6 of being connected with fixed subassembly 2, and external mold 6 is the arc structure.

Further, as shown in fig. 1 to 4, the radian of the outer mold 6 is the same as that of the inner mold 4, the surfaces of the inner mold 4 and the outer mold 6 contacting the steel pipes are both provided with arc-shaped grooves adapted to the steel pipes, the outer mold 6 and the inner mold 4 can be integrally cast by using aluminum alloy materials or cast steel materials, if the weight of the outer mold 6 and the weight of the inner mold 4 are reduced, the aluminum alloy materials can be selected for manufacturing, it is worth mentioning that the model specifications of the outer mold 6 and the inner mold 4 can be matched and replaced according to the model of the corresponding steel pipes, and the steel pipes of different models are provided with the inner mold 4 and the outer mold 6 adapted in a set.

Further, as shown in fig. 1, it should be noted that the inner mold 4 in the drawing is a mold capable of bending one steel pipe, and the outer mold 6 in the drawing is a mold capable of bending three steel pipes simultaneously, and the drawing is only a pattern diagram shown by different molds of the inner mold 4 and the outer mold 6, and the molds of the inner mold 4 and the outer mold 6 are both in a set type in actual operation.

Connection panel 5's fixed surface installs spacing response piece 8, spacing response piece 8's quantity is 3 bases, and 8 equidistance of spacing response piece distribute on connection panel 5's center pin, spacing response piece 8 passes through the drive module electric connection that is equipped with on wire and the electric jar 1, control panel through being equipped with on the electric jar 1 sets up the distance of the electric push rod propelling movement of electric jar 1, when the electric push rod propelling movement of electric jar 1 to the corresponding position of spacing response piece 8, the electric jar 1 of receiving the response then can reset the electric push rod of propelling movement, this electronic spacing technique is known open technology, do not describe here too much.

The two ends of the outer die 6 are fixedly provided with fine tuning screws 7, the fine tuning screws 7 can be used for fine tuning the radian of the steel pipe, after fine tuning, the bending degree of the steel pipe subjected to bending can be more accurate, the two ends of each outer die 6 are respectively and fixedly provided with one fine tuning screw 7, and the number of the fine tuning screws 7 is determined according to the model of the outer die 6, for example, the number of the fine tuning screws 7 is six when the outer die 6 is three steel pipes subjected to bending simultaneously.

The working principle is as follows: when the device is used, an inner mold 4 and an outer mold 6 matched with a steel pipe are found, then a convex block 21 and a concave block 22 are connected in a clamping mode, an electric push rod of an electric cylinder 1 penetrates through holes formed in the convex block 21 and the concave block 22, the inner mold 4 is sleeved into the electric push rod of the electric cylinder 1 after the electric push rod of the electric cylinder 1 penetrates through the convex block 21 and the concave block 22, a fine adjustment screw 7 is fine adjusted to required accuracy, a limiting induction block 8 is installed on the surface of a connecting panel 5, the electric cylinder 1 is electrically connected with an external power supply through a wire at the moment, the electric push rod pushing distance of the electric cylinder 1 is set through a control panel on the electric cylinder 1, when the device is ready for working, the steel pipe is placed between the inner mold 4 and the outer mold 6, and a switch of the electric cylinder 1 is started, and then the top bending work can be carried out.

If the number of the steel pipes to be bent is large, the inner die 4 and the outer die 6 can be replaced by dies capable of bending three steel pipes simultaneously, it should be noted that if the specification of the steel pipes is too large and exceeds the power of the existing electric cylinder 1, the electric cylinder 1 needs to be replaced by a larger power, and the problem that the power of the existing electric cylinder 1 cannot bend the steel pipes with large specifications is avoided.
