Description

Technical Field

[0001] The invention relates to the technical field of profile processing equipment, and in particular to a profile bending machine. Background Art

[0002] Conventional bending of existing profiles is generally performed by rolling wheels arranged in a triangular shape, and this processing method generally processes products with relatively stable structures and small bending dimensions. However, for profiles with multiple track grooves, the width dimension is relatively large. At the same time, when the horizontal plane relative to the width dimension needs to be bent, the structure of the intermediate separating track grooves is prone to destructive bending. At the same time, due to the large width dimension of the profile, direct rolling bending requires a great rolling force, which can easily damage the profile. Summary of the invention

[0003] The technical problem to be solved by the embodiments of the present invention is to provide a profile bending machine that can bend a profile with multiple track grooves without causing adverse deformation of the profile.

[0004] In order to solve the above technical problems, an embodiment of the present invention provides a profile bending machine for bending a profile having a plurality of track grooves, the profile bending machine comprising a bending mechanism, a feeding mechanism for conveying the profile to the bending mechanism, and a side top mechanism provided on one side of the bending mechanism, the profile is moved to the bending mechanism through the feeding mechanism, and the profile is bent toward the side top mechanism by the bending mechanism;

[0005] Wherein, the bending mechanism comprises a bending drive assembly for being placed in the track groove, a translation drive seat and a bending drive mechanism for driving the translation drive seat to move toward the side top mechanism, and a preset number of the bending drive assemblies are arranged on the translation drive seat;

[0006] The bending drive assembly comprises a contact block with an elliptical profile and a rotation drive mechanism for driving the contact block to rotate, wherein the contact block is mounted on the translation drive seat through the rotation drive mechanism so as to be driven by the translation drive seat to pull the profile toward the side top mechanism;

[0007] A plurality of the bending mechanisms are distributed at intervals along the conveying direction of the feeding mechanism.

[0008] As an improvement of the above solution, the major axis length of the contact block is greater than the width of the track groove in which it is placed, and the minor axis length of the contact block is less than the width of the track groove in which it is placed, so that the profile can pass through the bending mechanism.

[0009] As an improvement of the above solution, the contact block includes a rotating sleeve for connecting to the rotation drive mechanism and a deformation buffer layer for wrapping the rotating sleeve, and the side wall of the rotating sleeve is wrapped with a preset number of layers of the deformation buffer layer to form an elliptical contour.

[0010] As an improvement of the above solution, the deformation buffer layer is made of an elastic material, and relative to the shaft sleeve, the hardness of the deformation buffer layer gradually decreases from the inside to the outside.

[0011] As an improvement of the above-mentioned scheme, the side pressing mechanism includes a pressing block and a pressing driving mechanism for driving the pressing block to press against the profile. The pressing block is provided with a pressing side wall with a preset contour. The profile is pressed against the pressing side wall through the contact block so that the profile is bent and deformed along the preset contour.

[0012] As an improvement of the above solution, the rotation drive mechanism includes an output shaft connected to the rotating shaft sleeve and a motor body for driving the output shaft to rotate, and the rotating shaft sleeve is sleeved on the output shaft.

[0013] As an improvement of the above solution, the profile of the rotating shaft sleeve is elliptical and is made of hard material.

[0014] As an improvement of the above solution, the rotation drive mechanism also includes an auxiliary torsion spring, one end of which is connected to the rotating shaft sleeve, and the other end is connected to the main housing, so as to increase the initial rotation resistance of the contact block through the auxiliary torsion spring.

[0015] As an improvement of the above solution, the feeding mechanism includes a transport roller group and a synchronous driving mechanism for supporting and transporting the profile, the transport roller group includes a plurality of driving rollers, and the synchronous driving mechanism drives each of the driving rollers to rotate;

[0016] The driving rollers are distributed on both sides of the bending driving assembly.

[0017] As an improvement of the above scheme, the feeding mechanism also includes a roller frame and a lifting mechanism for driving the roller frame to rise and fall. The upper roller group and the synchronous drive mechanism are installed on the roller frame to separate the profile from the contact block by driving the driving roller to rise.

[0018] The implementation of the present invention has the following beneficial effects:

[0019] An embodiment of the present invention discloses a profile bending machine, comprising a bending mechanism, a feeding mechanism for conveying profiles to the bending mechanism, and a side top mechanism arranged on one side of the bending mechanism. The profile is moved to the bending mechanism through the feeding mechanism, and the bending mechanism bends the profile toward the side top mechanism to cooperate with the side top mechanism to apply force to bend the profile, thereby reducing the probability of destructive deformation of the profile.

[0020] Moreover, the bending mechanism comprises a bending drive assembly for being placed in the track groove, a translation drive seat and a bending drive mechanism for driving the translation drive seat to move toward the side top mechanism, and a preset number of the bending drive assemblies are arranged on the translation drive seat;

[0021] Moreover, the bending drive assembly includes a contact block with an elliptical profile and a rotation drive mechanism for driving the contact block to rotate. The contact block is installed on the translation drive seat through the rotation drive mechanism so that the profile is pulled toward the side top mechanism under the drive of the translation drive seat; along the conveying direction of the feeding mechanism, a plurality of the bending mechanisms are distributed at intervals.

[0022] Therefore, when bending is required, the bending drive assembly can bend the profile from the inside, so that the profile can obtain a uniform bending effect, thereby greatly reducing the problem of destructive deformation caused by excessive local stress.

[0023] Moreover, the elliptical design of the contact block and the setting of the rotation drive mechanism can control the rotation of the contact block through the rotation drive mechanism during the bending process of the profile, so that the contact block and the bending deformation of the profile are more closely fitted, thereby further reducing the problem caused by excessive local stress.

[0027] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] See also Figure 1 , 2and 3. An embodiment of the present invention provides a profile bending machine, comprising a bending mechanism, a feeding mechanism 1 for conveying the profile to the bending mechanism, and a side top mechanism 2 arranged on one side of the bending mechanism, wherein the profile is moved to the bending mechanism through the feeding mechanism 1, and the bending mechanism bends the profile toward the side top mechanism 2; wherein the bending mechanism comprises a bending drive assembly 3 for being placed in the track groove, a translation drive seat 4, and a bending drive mechanism for driving the translation drive seat 4 to move toward the side top mechanism 2, and a preset number of the bending drive assemblies 3 are arranged on the translation drive seat 4; the bending drive assembly 3 comprises a contact block 31 with an elliptical profile and a rotation drive mechanism for driving the contact block 31 to rotate, and the contact block 31 is installed on the translation drive seat 4 through the rotation drive mechanism, so as to be driven by the translation drive seat 4 to pull the profile toward the side top mechanism 2; along the conveying direction of the feeding mechanism 1, a plurality of the bending mechanisms are distributed at intervals. The bending drive mechanism can be a pneumatic telescopic rod mechanism, a hydraulic telescopic rod mechanism or a screw transmission mechanism in the prior art. Preferably, the bending drive mechanism is a screw transmission mechanism. Accordingly, the translation drive seat 4 is provided with a screw hole adapted to the screw 5 of the screw transmission mechanism.

[0029] Specifically, the long axis length of the contact block 31 is greater than the width of the track groove in which it is placed, so as to ensure that the contact block 31 can contact the groove wall of the track groove. Correspondingly, the short axis length of the contact block 31 is less than the width of the track groove in which it is placed, so that the profile can pass through the bending mechanism. Therefore, the rotation of the contact block 31 can be controlled to realize whether it is clamped and fixed with the profile.

[0030] The contact block 31 includes a rotating shaft sleeve 311 for connecting with the rotating drive mechanism and a deformation buffer layer 312 for wrapping the rotating shaft sleeve 311. The side wall of the rotating shaft sleeve 311 is wrapped with a preset number of layers of the deformation buffer layer 312 to form an elliptical profile. The arrangement of the deformation buffer layer 312 can better fit the groove wall of the track groove, thereby avoiding the problem of excessive local stress during the bending process of the profile.

[0031] Moreover, for the elliptical design of the outer contour of the contact block 31, an elliptical contour with a matching eccentricity can be selected according to the curvature requirements of the bending process, that is, the larger the eccentricity, the flatter the ellipse is relatively, and the smaller the eccentricity, the rounder the ellipse is relatively.

[0032] Furthermore, in order to ensure the bending shaping effect of the contact block 31, the deformation buffer layer 312 is made of elastic material, and the hardness of the deformation buffer layer gradually decreases from the inside to the outside relative to the shaft sleeve 311. This is to avoid the elastic deformation space of the contact block 31 being too large, which may cause random undesirable deformation during the bending deformation process. Common materials with different hardness include silicone, rubber, polyurethane, plastic, etc.

[0033] The side push mechanism 2 includes a push block 21 and a push drive mechanism 22 for driving the push block 21 to press against the profile. The push block 21 is provided with a push side wall with a preset contour. The profile is pressed against the push side wall through the contact block 31, so that the profile is bent and deformed along the preset contour. Accordingly, based on the conveying direction along the feeding mechanism 1, a plurality of the bending mechanisms are spaced apart, which can cooperate with the side push mechanism 2 to perform wave-shaped bending processing on the profile. Preferably, the side push mechanism 2 can be arranged on both sides of the profile. The push drive mechanism 22 is preferably selected from the pneumatic telescopic rod mechanism, hydraulic telescopic rod mechanism or screw transmission mechanism of the prior art.

[0034] Correspondingly, the rotation drive mechanism includes an output shaft 32 connected to the rotating shaft sleeve 311 and a motor body 33 for driving the output shaft to rotate, and the rotating shaft sleeve 311 is sleeved on the output shaft 32. Preferably, the rotating shaft sleeve 311 has an elliptical profile and is made of a hard material, such as stainless steel. Therefore, the rotation direction of the contact block 31 can be controlled according to the requirements of the processing bending direction, so that the contact block 31 can better fit the groove wall of the track groove.

[0035] Furthermore, since the contact block 31 needs to provide resistance in the opposite direction to the bending direction, in order to reduce the power output requirement of the motor body, the rotation drive mechanism also includes an auxiliary torsion spring 34, one end of which is connected to the rotating shaft sleeve 311, and the other end is connected to the main body housing 33, so as to increase the initial rotation resistance of the contact block 31 through the auxiliary torsion spring 34. Thus, the auxiliary torsion spring 34 can cooperate with the rotation drive mechanism to apply force during the bending process of the profile. Preferably, the output shaft 32 can be equipped with a ratchet mechanism to lock the rotation of the output shaft in one direction.

[0036] The feeding mechanism 1 includes a transport roller group and a synchronous driving mechanism for supporting and transporting the profile, the transport roller group includes a plurality of driving rollers 11, and the synchronous driving mechanism drives each of the driving rollers to rotate; the driving rollers 11 are distributed on both sides of the bending drive assembly 3. The synchronous driving mechanism includes a synchronous belt 12 and a motor 13 for driving the synchronous belt, and the motor 13 drives each of the driving rollers 11 to rotate through the synchronous belt 12.

[0037] On the other hand, after the profile is bent, it will be blocked by the contact block 31 and cannot continue to move directly in the transportation direction. In order to facilitate the profile to be sent away after the bending process so that the subsequent profile can enter the bending mechanism for bending, the feeding mechanism 1 also includes a roller frame and a lifting mechanism 15 for driving the roller frame 14 to rise and fall. The upper roller group and the synchronous driving mechanism are installed on the roller frame 14 to drive the driving roller 11 to rise, so that the profile is separated from the contact block 31, and then the bent profile can be sent out above the bending mechanism under the transportation of the driving roller 11.

[0038] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
