Description

Technical Field

[0001] This utility model relates to the field of metal sheet processing technology, specifically an automatic feeding device for a shearing machine. Background Technology

[0002] When processing sheet metal, the raw materials are usually cut to a fixed length and require secondary trimming to obtain good edge quality and perpendicularity of the right-angled edges. This process is generally carried out manually using a shearing machine.

[0003] In the prior art, CN107662020A, disclosed on February 6, 2018, describes a CNC automatic feeding and indexing shearing machine. This machine achieves automatic feeding of the shearing machine. However, the step of fixing the workpiece to the feeding device still requires manual operation. When fixing the workpiece to the feeding device, the center of the workpiece needs to be fixed at the rotating part of the feeding device, and manual operation inevitably introduces errors. Summary of the Invention

[0004] In order to overcome the defects in the prior art, this utility model provides an automatic feeding device for a shearing machine. This feeding device can automatically locate the geometric center between plates of different sizes to meet the accuracy requirements of plate processing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an automatic feeding device for a shearing machine, comprising:

[0006] The support platform is located on one side of the shearing machine inlet;

[0007] A conveying device is provided on the support platform. The conveying device includes a clamping assembly and a conveying unit connected to the clamping assembly. The conveying unit is used to drive the clamping assembly to move toward or away from the shearing machine inlet.

[0008] A positioning unit is disposed on the support platform. The positioning unit includes a first positioning element, a second positioning element, a first driving mechanism connected to the first positioning element for adjusting the position of the first positioning element, and a second driving mechanism connected to the second positioning element for adjusting the position of the second positioning element. When the plate is in the clamping position, the first positioning element and the second positioning element are in contact with two adjacent sides of the plate, respectively.

[0009] The clamping position is the position where the plate is clamped by the clamping assembly after being positioned by the first positioning member and the second positioning member. The center of the plate at the clamping position is opposite to the center of the clamping assembly.

[0010] Through the above scheme, the positions of the first positioning member and the second positioning member can be adjusted by the first driving mechanism and the second driving mechanism, thereby accommodating plates of different sizes and ensuring that the center of the positioned plate is relative to the clamping assembly.

[0011] Furthermore, both the first and second positioning components are connected to telescopic cylinders, which can drive the first and second positioning components to rise above or fall below the upper edge of the support platform. During feeding, the telescopic cylinders drive the first and second positioning components to fall below the upper edge of the support platform, facilitating the movement of the sheet metal.

[0012] Furthermore, the first driving mechanism can drive the first positioning member to move along a first direction, and the second driving mechanism can drive the second positioning member to move along a second direction, wherein the first direction is parallel to the feeding direction and the second direction is perpendicular to the feeding direction.

[0013] Furthermore, the conveying unit includes a bracket connected to the support platform, a cantilever slidably connected to the bracket, and a first motor capable of driving the cantilever to move along the feeding direction.

[0014] Furthermore, the clamping assembly includes a pressure rotating unit, which includes a rotating component slidably connected to the cantilever, a second motor for driving the rotating component to move toward the plate, and a pressure rod connected to the rotating component, the rotating component being able to drive the pressure rod to rotate.

[0015] Furthermore, the clamping assembly also includes a follower unit, which includes a base slidably connected to the support platform. The base can move together with the cantilever. The base is provided with a rotating seat, which is disposed opposite to the pressure rod and can rotate on its own. The rotating seat is used to cooperate with the pressure rod to clamp the plate.

[0016] Furthermore, the rotating component includes a cam divider, a first slide rail is provided on the cantilever, the cam divider is connected to the first slide rail, and the pressure rod is fixedly connected to the output shaft of the cam divider. Using a high-precision cam divider as the rotating device ensures the diagonal accuracy of the sheet metal.

[0017] Furthermore, a brush plate is provided on the support platform. The flexible brush plate is used to protect the board and prevent it from being scratched.

[0018] Furthermore, the brush plate surface of the support platform is inlaid with omnidirectional balls. The omnidirectional balls are used to support the plates and facilitate the adjustment of the plate positions.

[0019] Furthermore, the first drive mechanism and the second drive mechanism include a conveyor belt arranged along the extension direction of the channel, the conveyor belt being sleeved between two drive wheels, at least one of the drive wheels being connected to a third motor, and the first positioning member, the second positioning member and the conveyor belt being fixedly connected.

[0020] Based on the above technical solution, the beneficial effects of this utility model are as follows:

[0021] In this application, the host computer controls the movement of the first and second positioning components according to the size of the plate to ensure that the center of the plate is relative to the pressure bar, thereby meeting the accuracy requirements of the plate processing;

[0022] This application uses a high-precision cam divider to control the rotation of the pressure bar, thereby achieving precise rotation of the workpiece.

[0033] Example: Combining Figure 1-5 As shown, this embodiment discloses an automatic feeding device for a shearing machine, comprising:

[0034] A support platform 1 is located on one side of the inlet of the shearing machine (not shown in the figure). The support platform 1 includes a frame, on which two parallel rotating tables are hinged. Each rotating table has a brush surface with embedded omnidirectional balls. The flexible brush surface protects the sheet metal from scratches. The omnidirectional balls support the sheet metal and facilitate adjustment of its position.

[0035] One side of each of the two tilting tables is hinged to the frame, and the other side of the tilting tables is supported by a first cylinder 14. When the first cylinder 14 extends, the tilting tables unfold to form a plane; when the first cylinder 14 retracts, the tilting tables close to form a cabinet. When the automatic feeding device of this shearing machine is not in use, the first cylinder 14 retracts, making the support platform 1 a cabinet, reducing the floor space.

[0036] A base slide rail is provided between the two flipping tables, and the base slide rail extends toward the shearing machine. A base 31 is connected to the base slide rail, and the base 31 can slide along the base slide rail.

[0037] A conveying unit 11 is provided on the support platform 1. The conveying unit 11 includes a bracket 12 fixedly connected to the support platform 1 and a cantilever 13 sleeved on the bracket 12. The bracket 12 is L-shaped, fixedly connected to the support platform 1, and extends toward the shearing machine. A third slide rail is provided on the bracket 12, which is arranged along the length of the bracket 12. The cantilever 13 is connected to the third slide rail, and a first motor is connected to the cantilever 13. The first motor is used to drive the cantilever 13 to move along the third slide rail.

[0038] The cantilever 13 is connected to a material pressing and rotating unit 2. Driven by the first motor, the cantilever 13 moves closer to or further away from the shearing machine along the third slide rail, thereby realizing material feeding.

[0039] The material pressing rotation unit 2 includes a cam divider 21 connected to the cantilever 13, and a material pressing rod 22 fixedly connected to the output shaft of the cam divider 21. The cantilever 13 has a first vertical slide rail, and the cam divider 21 is connected to the first slide rail. The cam divider 21 is also connected to a second motor that drives it to move along the first slide rail. The second motor drives the cam divider 21, along with the material pressing rod 22, to move closer to or away from the plate along the first slide rail. The cam divider 21 is connected to a frequency converter and a reducer to control the rotation of the cam divider 21 with the material pressing rod 22, thereby driving the plate to rotate.

[0040] The support platform 1 is equipped with a follower unit 3 relative to the conveying unit 11. The follower unit 3 is used to cooperate with the pressing and rotating unit 2 to clamp the plate. The follower unit 3 includes the aforementioned base 31. The base 31 is equipped with a rotating seat 32 relative to the pressing rod 22. The base 31 has a mounting hole, and a bearing is installed in the mounting hole. The rotating seat 32 is connected to the bearing. The rotating seat 32 is used to cooperate with the pressing rod 22 to clamp the plate, and the rotating seat 32 can rotate on its own axis.

[0041] With the above technical solution, the plate is placed on the rotating seat 32, and the second motor drives the cam divider 21 to move the pressure rod 22 toward the plate, clamping the plate between the pressure rod 22 and the rotating seat 32. Since the rotating seat 32 can rotate, the variable frequency motor and reducer can control the pressure rod 22 to rotate together with the plate.

[0042] In this application, the support platform 1 is provided with channels 42 extending along a first direction and a second direction. The first direction is parallel to the feeding direction, and the second direction is perpendicular to the feeding direction. A second slide rail 46 is provided within the channel 42, extending along the length of the channel 42. A positioning element is connected to the second slide rail 46, and the positioning element is connected to a driving mechanism. The positioning element includes a first positioning pin and a second positioning pin 41, and the driving mechanism includes a first driving mechanism and a second driving mechanism. The first positioning pin is connected to the second slide rail 46 along the first direction, and the second positioning pin 41 is connected to the second slide rail 46 along the second direction. The first positioning pin is connected to the first driving mechanism to drive the first positioning pin to move along the first direction (not shown in the figure), and the second positioning pin 41 is connected to the second driving mechanism to drive the second positioning pin 41 to move along the second direction. The first positioning pin and the second positioning pin 41 form a 90° right-angle positioning. By placing the two edges of the plate against the first positioning pin and the second positioning pin 41 respectively, the positioning of the plate is completed. In this application, the positions of the first positioning pin and the second positioning pin 41 are adjusted by a drive mechanism to adapt to plates of various sizes.

[0043] The drive mechanism includes a conveyor belt 43 extending along the channel 42. The conveyor belt 43 is sleeved between two drive wheels 44, one of which is connected to a third motor 45. The positioning member and the conveyor belt 43 are fixedly connected.

[0044] In this application, the drive mechanism is connected to a host computer. The operator inputs the size of the board into the host computer, and the host computer controls the first drive mechanism and the second drive mechanism to move the first positioning pin and the second positioning pin 41 respectively, so that the center of the board after being positioned by the first positioning pin and the second positioning pin 41 is aligned with the pressure rod 22, thereby ensuring the diagonal accuracy of the board.

[0045] Optionally, the positioning member is connected to a telescopic cylinder 411, which is fixedly connected to the conveyor belt 43. The telescopic cylinder 411 can drive the positioning member to rise above or fall below the upper edge of the support platform 1.

[0046] The automatic feeding device for the shearing machine disclosed in this application is used as follows:

[0047] The staff inputs the size of the board into the host computer, and the host computer controls the drive mechanism to move the positioning part to the corresponding position to ensure that the center of the board positioned by the first positioning pin and the second positioning pin 41 is opposite to the pressure rod 22.

[0048] After the plate is positioned using the first positioning pin and the second positioning pin 41, the second motor drives the cam divider 21 to move towards the plate with the pressure rod 22 and clamp the plate between the pressure rod 22 and the rotating seat 32. The telescopic cylinder 411 drives the positioning member to descend below the upper edge of the support platform 1 so that the plate can move.

[0049] The first motor drives the cantilever 13 to move towards the shearing machine with the cam divider 21 to complete the feeding. When the shearing machine is working, the frequency converter and reducer control the cam divider 21 to drive the pressure rod 22 to rotate with the plate to meet the shearing requirements.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the utility model. Therefore, the content of this specification should not be construed as a limitation of the utility model.
