Referring to fig. 1 and 2, an embodiment of the present application provides a bending apparatus 100. The bending apparatus 100 is used to bend the support rod 10 to achieve a desired degree of bending of the support rod 10. Before the bending apparatus 100 bends the support rod 10, the support rod 10 may be a straight rod in an initial state, or may be a rod having a certain degree of curvature as shown in fig. 1.
The bending apparatus 100 includes: a base 110, a loading member 120, and a first blocking member 130.
The base 110 is provided with a fixing structure 140. The fixing structure 140 is configured to fix an end of the support rod 10 along a first direction, where the length direction of the support rod 10 is the first direction, so as to prevent the support rod 10 from rotating or sliding during the bending process.
The loading member 120 is connected with the base 110. The loading member 120 can move in a linear path in the second direction XX' with respect to the base 110 to load the support bar 10, thereby bending the support bar 10. That is, the loading path of the loader 120, i.e., the linear path, the second direction XX' is along the linear direction. The second direction XX' may be in a radial direction of the support bar 10. Of course, the second direction XX' may be any other direction different from the first direction, which is not limited.
The first blocking member 130 is disposed on the base 110. The first blocking member 130 is located on a different side of the support rod 10 in the second direction XX 'from the loading member 120, and therefore, when the loading member 120 loads the support rod 10, the first blocking member 130 blocks the support rod 10 on a side of the support rod 10 facing away from the loading member 120 in the second direction XX'.
In the first direction, the fixed structure 140, the loading member 120 and the first blocking member 130 are sequentially arranged at intervals, and the loading path of the loading member 120 is along the linear path of the second direction XX ', so that the linear path when the loading member 120 loads the support rod 10 can be located between the fixed structure 140 and the first blocking member 130, and thus the deformation path at the loaded position of the support rod 10 is along the second direction XX' and can be located between the fixed structure 140 and the first blocking member 130.
It will be appreciated that when the loading distance of the loader 120 is small, the loading path of the loader 120 is short, and thus the loading path may not extend between the fixed structure 140 and the first stopper 130, however, since the fixed structure 140, the loader 120, and the first stopper 130 are sequentially spaced apart in the first direction, an extension line of the loading path of the loader 120 can be located between the fixed structure 140 and the first stopper 130, and thus the deformation path at the loaded position of the support rod 10 can be located along the second direction XX' and an extension line of the deformation path can be located between the fixed structure 140 and the first stopper 130.
When the bending apparatus 100 is used for bending the support rod 10, since the linear path or the extension line thereof is located between the fixing structure 140 and the first blocking member 130 when the loading member 120 loads the support rod 10 along the linear path in the second direction, the deformation path at the loaded position of the support rod 10 can be defined along the second direction XX', and the deformation path at the loaded position of the support rod 10 or the extension line thereof is located between the fixing structure 140 and the first blocking member 130, so that the bending degree of the support rod 10 at the loaded position is increased. Moreover, since the fixing structure 140 fixes one end of the support rod 10 along the first direction, and the first blocking member 130 blocks the support rod 10 at a side of the support rod 10 departing from the loading member 120 along the second direction XX', the support rod 10 is not easy to slip when the loading member 120 loads the support rod 10 along the straight path of the second direction, and the support rod 10 is not easy to rotate and slip, so that the deformation direction and the deformation amount of the loaded position of the support rod 10 can be accurately controlled, and further, the support rod 10 can be bent to a desired bending degree accurately, and the support rod 10 can achieve a good use effect.
Referring to fig. 1, in an embodiment, the bending apparatus 100 further includes a second blocking member 150, and the second blocking member 150 is disposed on the base 110. The second blocking member 150 is located on a different side of the support rod 10 from the loading member 120 in the second direction XX ', and thus, when the loading member 120 loads the support rod 10, the second blocking member 150 blocks the support rod 10 on a side of the support rod 10 facing away from the loading member 120 in the second direction XX'.
In the first direction, the fixing structure 140, the second stopper 150, the loading member 120, and the first stopper 130 are sequentially disposed at intervals, and thus, a straight line path when the supporting rod 10 is loaded by the loading member 120 or an extension line of the straight line path can be located between the second stopper 150 and the first stopper 130, and thus, a deformation path or an extension line of the deformation path at the loaded position of the supporting rod 10 is located between the second stopper 150 and the first stopper 130. It follows that by providing a second stop 150, it is convenient to control the deformation path or an extension of the deformation path at the loaded position of the support rod 10 between the second stop 150 and the first stop 130, so that the loaded position of the support rod 10 does not have to be too dependent on the position of the fixed structure 140. Therefore, the support rod 10 can be conveniently loaded at a reasonable loaded position by only reasonably arranging the positions of the second blocking member 150 and the first blocking member 130, thereby being beneficial to achieving a better bending effect of the support rod 10.
Referring to fig. 2, in an embodiment, the loading element 120 is provided with a groove 101 for fitting with the outer circumferential surface of the support rod 10. Specifically, when the loading member 120 loads the support rod 10, the opening of the groove 101 is directed toward the second direction XX' and toward the support rod 10, so that the outer circumferential surface of the support rod 10 can be partially fitted with the groove 101, thereby enabling the loading member 120 to be more closely fitted with the support rod 10, and facilitating the loading member 120 to provide a loading force to the support rod 10.
In an embodiment, the loading element 120 is able to rotate with respect to the base 110 about the axis of the third direction ZZ ' to adjust the angle about the axis of the third direction ZZ ', which is perpendicular to the second direction XX '. The third direction ZZ 'is, for example, an axial direction of the loading unit 120, and an axis of the third direction ZZ', i.e., an axis of the loading unit 120, i.e., the loading unit 120, can rotate around its own axis relative to the base 110 to adjust its own angle. The number of the grooves 101 is plural. The plurality of grooves 101 are arranged in sequence around the axis of the third direction ZZ'. Different grooves 101 are used to adapt different support bars 10.
Since the third direction ZZ ' is perpendicular to the second direction XX ', and the plurality of grooves 101 are sequentially arranged around the axis of the third direction ZZ ', by rotating the loading member 120 around the axis of the third direction ZZ ' with respect to the base 110 to adjust the angle, different grooves 101 can be oriented toward the second direction XX ' and toward the support rod 10, and thus different grooves 101 can be selectively engaged with the support rod 10. And because different grooves 101 are used for adapting to different support rods 10, the loading piece 120 can be tightly matched with different support rods 10, so that the loading piece 120 can provide loading force for different support rods 10, and the bending device 100 can bend different support rods 10.
In one embodiment, the plurality of grooves 101 are all arcuate grooves. The corresponding radius of the arc-shaped groove is adapted to the radius of the support rod 10, so that the outer circumferential surface of the support rod 10 can be closely attached to the groove wall of the arc-shaped groove, and the loading member 120 can provide a loading force to the support rod 10. It can be understood that the center of the arc groove is concentric with the axis of the support rod 10.
The radii of the different arc grooves are different from each other, so that the arc grooves with different radii can be adapted to the support rods 10 with different radii, and then the loading member 120 can be tightly matched with the support rods 10 with different radii to provide loading force, thereby facilitating the bending device 100 to bend the support rods 10 with different radii.
In other embodiments, the plurality of grooves may also be grooves of different shapes, respectively, so that the plurality of grooves can be adapted to support rods of different cross-sectional shapes, respectively. For example, one groove may be a circular arc-shaped groove so as to be able to fit a support rod having a circular cross section, and the other groove may be an elliptical arc-shaped groove so as to be able to fit a support rod having an elliptical cross section, without limiting the shape of the groove.
As shown in fig. 2, in one embodiment, the surface of the first blocking member 130 facing the support rod 10 is provided with a groove 102 for fitting with the outer circumferential surface of the support rod 10. When the loading member 120 loads the support rod 10, the outer circumferential surface of the support rod 10 can be partially engaged with the groove 102, thereby stabilizing the engagement of the first blocking member 130 with the support rod 10.
In an embodiment, the surface of the second blocking member 150 facing the support rod 10 is provided with a groove (not shown) for fitting with the outer circumferential surface of the support rod 10. When the loading member 120 loads the support rod 10, the outer circumferential surface of the support rod 10 can be partially engaged with the groove, thereby stabilizing the engagement of the second stopper 150 with the support rod 10.
Referring to fig. 1 and 2, in one embodiment, bending apparatus 100 further includes a force input assembly 160. The force input assembly 160 is connected to the loading element 120, and the force input assembly 160 is configured to drive the loading element 120 to move along the second direction XX' relative to the base 110, so as to facilitate a loading process of the loading element 120.
In one embodiment, the force input assembly 160 is coupled to the base 110.
In an embodiment, the force input assembly 160 includes a screw 161 axially along the second direction XX'. The screw 161 is in threaded driving engagement with the loading member 120. The base 110 is provided with a guide groove 103. The loading member 120 and the guide slot 103 are slidably engaged along the second direction XX', so that when the screw 161 is rotated, the screw 161 can drive the loading member 120 to translate along the guide slot 103, thereby facilitating the loading process of the loading member 120.
In one embodiment, the screw 161 is rotatably connected to the base 110 to facilitate the operation of rotating the screw 161.
Specifically, referring to fig. 1 and 2, the base 110 includes a body 111 and a boss 112. The boss 112 protrudes from the body 111 along the third direction ZZ'. The screw 161 is inserted into the boss 112 and can rotate relative to the boss 112. The loading member 120 is disposed at one side of the boss 112 in the second direction XX'.
In one embodiment, an end of the screw 161 facing away from the loader 120 is provided with a handle 162, and the handle 162 is grasped to facilitate rotation of the screw 161.
In other embodiments, the force input assembly may take other configurations, such as a slider-crank configuration, or the like.
In one embodiment, the loading member 120 is able to rotate about the axis of the third direction ZZ ' with respect to the force input assembly 160, so that the loading member 120 is able to rotate indirectly about the axis of the third direction ZZ ' with respect to the base 110 to adjust the angle about the axis of the third direction ZZ ' with respect to the base 110.
Referring to FIG. 1, in one embodiment, the loading element 120 is coupled to the force input assembly 160 using a threaded connection 170. When the angle of the loading member 120 needs to be adjusted, the threaded connection 170 is loosened, the loading member 120 is rotated to a desired angle, and then the threaded connection 170 is tightened, so that the loading member 120 is fixed to the force input assembly 160, thereby achieving the angle adjustment of the loading member 120 about the axis of the third direction ZZ' with respect to the force input assembly 160.
In other embodiments, the loading element 120 and the force input assembly 160 may be connected by other connecting elements, as long as the loading element 120 can rotate around the axis of the third direction ZZ' relative to the force input assembly 160 to adjust the angle.
Referring to fig. 1 and 2, in one embodiment, a slider 190 is disposed at one end of the screw 161, and the loading member 120 is coupled to the slider 190 by a screw coupling 170, so that the loading member 120 is indirectly coupled to the screw 161. When the angle of the loading member 120 needs to be adjusted, the threaded connection 170 is loosened, the loading member 120 is rotated to a desired angle, and then the threaded connection 170 is tightened, so that the loading member 120 is fixed to the slider 190, thereby realizing the rotation of the loading member 120 about the axis of the third direction ZZ' relative to the screw 161.
The screw 161 is threadedly engaged with the slider 190 and thus indirectly threadedly engaged with the loading member 120. Since the slider 190 does not need to rotate when the loading member 120 rotates about the axis of the third direction ZZ ', even if the loading member 120 rotates about the axis of the third direction ZZ ', the screw 161 is engaged with the screw thread of the slider 190, so that the loading member 120 can smoothly load the support rod 10 in the second direction XX '.
The slider 190 is slidably engaged with the guide slot 103 in the second direction XX ', thereby indirectly slidably engaging the loading member 120 with the guide slot 103 in the second direction XX'. Since the slider 190 does not need to rotate when the loader 120 rotates about the axis of the third direction ZZ ', even if the loader 120 rotates about the axis of the third direction ZZ', the slider 190 can be slidably engaged with the guide slot 103 in the second direction XX 'so that the guide slot 103 can guide the loader 120 to load the support rod 10 in the second direction XX'.
In other embodiments, the slide block and the loading element may also be integrally formed or separately formed and then fixedly connected, and a plurality of threaded holes are formed in the slide block, and the plurality of threaded holes are sequentially arranged around the axis in the third direction. When the loading piece rotates around the axis of the third direction, the sliding block synchronously rotates around the axis of the third direction, so that when the angle of the loading piece is adjusted in place, the screw rod can still be matched with the threaded hole, and the loading piece is driven to load the supporting rod along the second direction. It will be appreciated that when the loading member is adjusted to different angles, the threaded rod will engage different threaded holes.
In other embodiments, the loading element 120 and the sliding block 190 may be connected by other connecting elements, as long as the loading element 120 can rotate around the axis of the third direction ZZ' relative to the sliding block 190 to adjust the angle.
Referring to fig. 1, in an embodiment, the base 110 is provided with a scale mark 180, and an extension direction of the scale mark 180 is along the second direction XX', so that a moving position of the loading member 120 can be indicated, a loading distance of the loading member 120 can be conveniently and quantitatively controlled, and the loading member 120 can repeatedly load the plurality of support rods 10 with the same loading distance, that is, the plurality of support rods 10 can be repeatedly bent to the same bending degree.
In one embodiment, the end of the fixing structure 140 for connecting with the support rod 10 can be adjusted in position relative to the base 110, so that the position of the end of the support rod 10 connected with the fixing structure 140 (i.e. the end of the support rod 10 along its length) can be adjusted. For the support rods 10 with different lengths, the loaded position of the support rod 10 can be adjusted by adjusting the position of one end (i.e., one end of the support rod 10 along the length direction) of the support rod 10 connected with the fixing structure 140, so that the support rod 10 can be loaded at a reasonable loaded position, and the support rod 10 can achieve a better bending effect.
In one embodiment, the fixed structure 140 includes a linkage assembly including at least one link 141. One end of the connecting rod assembly is fixedly connected with the base 110 and can adjust a relative angle with the base 110, and the other end of the connecting rod assembly is fixedly connected with one end of the support rod 10 along the first direction so as to fix one end of the support rod 10 along the first direction. By adjusting the relative angle between the end of the connecting rod assembly connected to the base 110 and the base 110, the position of the end of the connecting rod assembly connected to the support rod 10 can be adjusted, and the position of the end of the support rod 10 connected to the connecting rod assembly (i.e. the end of the support rod 10 along the length direction thereof) can be adjusted.
Specifically, one end of the link assembly connected to the base 110 is connected to the base 110 by a threaded connection. When the angle of the connecting rod assembly connected to one end of the base 110 needs to be adjusted, the threaded connecting piece is loosened, the connecting rod assembly connected to one end of the base 110 is rotated to a required angle, and then the threaded connecting piece is screwed down, so that the connecting rod assembly connected to one end of the base 110 can be fixed with the base 110.
In one embodiment, the connecting rod assembly includes a plurality of connecting rods 141 fixedly connected in sequence, and adjacent connecting rods 141 are capable of adjusting relative angles. By adjusting the relative angle of the adjacent connecting rods 141, the position of the end of the connecting rod assembly connected to the support rod 10 can be adjusted more flexibly.
Specifically, the adjacent links 141 are connected by a threaded connection. When the relative angle of the adjacent connecting rods 141 needs to be adjusted, the threaded connecting piece is loosened, so that the adjacent connecting rods 141 rotate to the required relative angle, and then the threaded connecting piece is screwed down, so that the adjacent connecting rods 141 can be fixed. Specifically, in the present embodiment, the number of the connecting rods 141 is two, but the number of the connecting rods 141 may be three or more.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
