Description

Technical Field

[0001] This utility model relates to the field of bending machines, and in particular to an auxiliary positioning structure for bending machines. Background Technology

[0002] A bending machine is a device that can bend thin sheet metal workpieces. Existing bending machines mainly rely on the operator's experience to manually place and position the workpiece. This method is prone to errors, resulting in inaccurate positioning and bending errors. Therefore, we propose an auxiliary positioning structure for bending machines to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to solve the following problems existing in the prior art: existing bending machines mainly rely on the operator's experience to manually place and position the workpiece, which is prone to errors, resulting in inaccurate positioning and bending errors.

[0004] To address the problems existing in the prior art, this utility model provides an auxiliary positioning structure for a bending machine, including a positioning platform. The positioning platform is set in front of the lower die base of the bending machine via a connecting piece. Electric guide rails are provided on both sides inside the positioning platform. Positioning seats are provided on the electric guide rails via sliders. Adjustment grooves and positioning grooves are respectively opened inside the positioning seats. Two sets of clamping components are respectively provided on the adjustment grooves.

[0005] Furthermore, the adjustment groove is located above the positioning groove, and the length of the adjustment groove matches that of the positioning groove.

[0006] Furthermore, multiple pressure sensors are also provided on the inner wall of the adjustment groove.

[0007] Furthermore, the clamping assembly includes a cylinder and a pressure block. The cylinder is slidably disposed in an adjustment groove via an adjustment block, and the telescopic end below the cylinder is connected to the pressure block.

[0008] Furthermore, a rubber gasket is provided at the bottom end of the pressure block.

[0009] Furthermore, a controller is provided on one side of the positioning platform, and the controller is electrically connected to the control components of the electric guide rail and the cylinder.

[0010] Compared with the prior art, the beneficial effects of this utility model are: The operator first inserts one end of the thin sheet workpiece into the positioning groove of the positioning seat. The extension end of the cylinder presses down to press the pressure block against both sides of the workpiece, achieving rapid clamping. Immediately after the electric guide rail starts, the slider moves the positioning seat and the workpiece towards the bending area of ​​the bending machine until the other end of the workpiece abuts against the abutment block inside the bending machine. The pressure sensor detects the pressure change caused by the contact and extrusion, and controls the electric guide rail to stop running, thereby achieving the effect of auxiliary positioning. Furthermore, during the subsequent bending process, the clamped workpiece will not have bending errors due to offset or movement, increasing the practicality of this device.

[0013] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation details without creative effort are all within the protection scope of this invention.

[0014] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0015] Example 1 like Figure 1-3 As shown, an auxiliary positioning structure for a bending machine includes a positioning platform 1. The positioning platform 1 is set in front of the lower die base of the bending machine through a connector. Electric guide rails 8 are provided on both sides inside the positioning platform 1. Positioning seats 3 are provided on the electric guide rails 8 through sliders 7. Adjustment grooves 5 and positioning grooves 9 are respectively opened inside the positioning seats 3. Two sets of clamping components are respectively provided on the adjustment grooves 5. In this embodiment, the adjustment groove 5 is opened above the positioning groove 9, and the length of the adjustment groove 5 matches that of the positioning groove 9. Multiple pressure sensors 4 are also provided on the inner wall of the adjustment groove 5. The clamping assembly includes a cylinder 2 and a pressure block 10. The cylinder 2 is slidably set in the adjustment groove 5 through the adjustment block. The telescopic end of the cylinder 2 is connected to the pressure block 10. The bottom end of the pressure block 10 is also provided with a rubber pad. A controller 6 is also provided on one side of the positioning table 1. The controller 6 is electrically connected to the control components of the electric guide rail 8 and the cylinder 2 respectively.

[0016] Working principle description: The operator first inserts one end of the thin plate workpiece into the positioning groove 9 of the positioning seat 3, and makes one end of the workpiece abut against the inner wall of the positioning groove 9. Then, the adjusting cylinder 2 is moved in the adjusting groove 5 to the appropriate position on both sides of the workpiece, so that the operator can make corresponding clamping adjustments according to the width of different workpieces. After the adjustment is completed, the operator starts the cylinder 2 through the operation controller 6. The extension end of the cylinder 2 presses down to make the pressure block 10 press against both sides of the workpiece, so as to achieve the purpose of quick clamping. Then, the electric guide rail 8 starts and drives the positioning seat 3 and the workpiece to move towards the bending area of ​​the bending machine through the slider 7 until the other end of the workpiece abuts against the abutment block in the bending machine. After the other end of the workpiece abuts against the abutment block, the pressure sensor 4 in the positioning groove 9 detects the pressure change and controls the electric guide rail 8 to stop running, thereby achieving the effect of auxiliary positioning. In addition, during the subsequent bending process, the clamped workpiece will not have bending errors due to offset or movement, increasing the practicality of this device.
