It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Example 1
The embodiment provides a transformer copper pipe bending tool, the structure of which is shown in fig. 1 and 2, the transformer copper pipe bending tool comprises two bending spanners 1, and the two bending spanners 1 form a pair of transformer copper pipe bending tools; the bending wrench 1 comprises a handle 11, a first pin shaft 12, a connecting rod 13 and a second pin shaft 14, wherein the first pin shaft 12 is fixedly arranged at one end of the handle 11; one end of the connecting rod 13 is slidably connected with the handle 11; the second pin 14 is fixedly arranged at one end of the connecting rod 13, which is far away from the handle 11, and a threading channel 10 for the copper pipe 100 to pass through is formed between the first pin 12 and the second pin 14.
The transformer copper pipe bending tool consists of two bending spanners 1, and the copper pipe can be bent by holding the two bending spanners 1 by two hands, so that the volume is small; moreover, the bending wrench 1 comprises a handle 11, a first pin shaft 12, a connecting rod 13 and a second pin shaft 14, and has a simple structure, so that the purchase cost is low.
In order to be suitable for bending operations of copper pipes with different sizes, as a preferred embodiment, one end of the connecting rod 13 is slidably connected with the handle 11, the handle 11 is a sleeve handle, and one end of the connecting rod 13 is slidably sleeved in the sleeve handle.
It will be appreciated that one end of the connecting rod 13 is slidably connected to the handle 11, so that the distance between the first pin 12 and the second pin 14 (i.e. the width of the threading channel 10) can be adjusted, and thus the bending operation of copper pipes with different sizes can be applied.
In order to position the first pin 12 and the second pin 14 on the handle 11 and the connecting rod 13 which are connected in a sliding manner so as to avoid mutual deflection of the first pin 12 and the second pin 14 during operation, as a preferred embodiment, the cross sections of the handle 11 and the connecting rod 13 are polygonal, and the inner diameter of the handle 11 is matched with the outer diameter of the connecting rod 13;

It can be appreciated that, since the cross sections of the handle 11 and the connecting rod 13 are polygonal, the connecting rod 13 only slides along the axial direction relative to the handle 11, but does not rotate around the axial direction, so that the copper tube 100 cannot be limited in the threading channel 10 between the first pin shaft 12 and the second pin shaft 14 due to the mutual deflection of the first pin shaft 12 and the second pin shaft 14 during operation is avoided, and therefore the copper tube 100 can be limited in the threading channel 10, and the copper tube 100 is convenient to fix.
In order to accurately adjust the width of the threading channel 10, as a preferred embodiment, the transformer copper pipe bending tool further includes an adjusting mechanism 15 for adjusting the width of the threading channel 10, referring to fig. 3, the adjusting mechanism 15 includes an end cover 151, an elastic member 152 and an adjusting bolt 153, wherein the end cover 151 is detachably and fixedly disposed at an end portion of the handle 11 away from the connecting rod 13, and a threaded hole is formed in the end cover 151; the elastic element 152 is disposed in the handle 11 and between the end cover 151 and the connecting rod 13, two ends of the elastic element 152 are respectively fixedly connected with the end cover 151 and the connecting rod 13, specifically, the elastic element 152 is a spring, and the elastic element 152 is always in a stretched state when in operation; the adjusting bolt 153 is connected with a threaded hole on the end cover 151 in a matching manner, and the top end of the adjusting bolt 153 passes through the threaded hole and the elastic member 152 and then abuts against the end face of the connecting rod 13.
It can be appreciated that, since one end of the connecting rod 13 is slidably connected to the handle 11, the position of the connecting rod 13 can be adjusted along the axial direction by rotating the adjusting bolt 153, so as to adjust the distance between the first pin 12 and the second pin 14 (i.e. the width of the threading channel 10), and have higher adjustment accuracy.
It should be noted that, in addition to the mechanical driving in this embodiment, the adjusting mechanism 15 may be an electric driving, such as a telescopic driving member like an air cylinder, and the telescopic driving member is a prior art, so that details of how to use the electric driving will not be described here.
Further, length scales may be provided on the working surface of the connecting rod 13 and in the threading channel 10, so as to read the width value of the threading channel 10.
In order to improve the stability of the adjusting mechanism 15, so as to prevent the end portion of the connecting rod 13 from being separated from the handle 11, as a preferred embodiment, the top end of the adjusting bolt 153 is rotatably connected to the connecting rod 13 after passing through the threaded hole and the elastic member 152.
In order to avoid that the copper tube 100 is damaged or bending operation is affected due to interference between the copper tube 100 and the end of the handle 11 when the copper tube 100 is bent, as a preferred embodiment, a special-shaped notch 110 is formed at one end of the handle 11 near the connecting rod 13, so that the outer edge of the first pin 12 coincides with the end of the handle 11 or protrudes out of the end of the handle 11.

It should be noted that the bending tool for copper tube of transformer provided by the present utility model may have two different structures, that is, the protecting sleeve or the protecting roller 16 is disposed on the first pin 12 or the second pin 14; and two different structures correspond to two working states, namely, two bending wrenches 1 can rotate around the corresponding axis of the second pin shaft 14 at the same time, so that the transformer copper pipe bending tool can be opened or closed, no matter the transformer copper pipe bending tool is opened or closed, the copper pipe 100 can be subjected to bending operation, and corresponding working state diagrams can be respectively referred to fig. 1 and 4, specifically:
when the transformer copper pipe bending tool in fig. 1 bends the copper pipe 100, two bending wrenches 1 need to be rotated outwards around the corresponding axis of the second pin shaft 14 simultaneously to open the transformer copper pipe bending tool, and when the transformer copper pipe bending tool is opened, the first pin shaft 12 slides relative to the surface of the copper pipe 100, so that in order to prevent the first pin shaft 12 from scratching the surface of the copper pipe 100, the protection sleeve or the protection roller 16 is rotatably arranged on the outer surface of the first pin shaft 12; the structural schematic diagram of the bending wrench 1 corresponding to fig. 1 is shown in fig. 2;
when the transformer copper pipe bending tool in fig. 4 bends the copper pipe 100, two bending wrenches 1 need to be rotated inwards around the corresponding axes of the second pins 14 simultaneously to close the transformer copper pipe bending tool, and when the transformer copper pipe bending tool is closed, the second pins 14 slide relative to the surface of the copper pipe 100, so that in order to avoid the second pins 14 scratching the surface of the copper pipe 100, the protective sleeves or the protective rollers 16 are rotatably arranged on the outer surface of the second pins 14; fig. 4 is a schematic structural view of the bending wrench 1 corresponding to fig. 5.
It can be appreciated that, by movably arranging the protective sleeve or the protective roller 16 on the first pin shaft 12 or the second pin shaft 14, the surface of the copper tube 100 can be prevented from being scratched due to sliding of the first pin shaft 12 or the second pin shaft 14 relative to the surface of the copper tube 100 when bending the copper tube 100, and the protection effect on the copper tube 100 is improved.

In order to facilitate understanding of the present utility model, since the bending tool for the copper tube of the transformer provided by the present utility model has two different structures, the two different structures respectively correspond to different working states, but since the two different structures have smaller difference, and the two corresponding working states are only different in the direction of force application, the working principle of the present utility model will be described in detail below only with reference to fig. 1 to 3:
during operation, the adjusting bolt 153 is rotated according to the width of the copper pipe 100 to be bent, so as to drive the connecting rod 13 to axially move relative to the handle 11, thereby adjusting the width of the threading channel 10 between the first pin shaft 12 and the second pin shaft 14 until the width of the threading channel 10 is slightly larger than the size of the copper pipe 100, so that the copper pipe 100 is conveniently placed in the threading channel 10;
the left hand and the right hand hold the handles 11 of the two bending wrenches 1 to apply force outwards respectively, so that the two bending wrenches 1 simultaneously rotate outwards around the corresponding axial lines of the second pin shafts 14, the transformer copper pipe bending tool is opened until the copper pipe 100 is bent to an expected angle, and the application of force to the two bending wrenches 1 is stopped, so that the bending work of the copper pipe 100 is completed;
similarly, the left hand and the right hand hold the handles 11 of the two bending wrenches 1 respectively to apply force inwards, so that the two bending wrenches 1 simultaneously rotate inwards around the corresponding axes of the second pin shafts 14, the transformer copper pipe bending tool is closed, and the force application on the two bending wrenches 1 is stopped until the copper pipe 100 is bent to the expected angle, thus completing the bending work of the copper pipe 100.
