Description

Technical Field

[0001] This utility model relates to the field of back gauge technology for bending machines, and in particular to a mini back gauge specifically for bending machines. Background Technology

[0002] Sheet metal bending machines play a crucial role in the sheet metal manufacturing industry, and the back gauge of the bending machine is a key factor determining the bending accuracy of sheet metal. In traditional back gauges, the linear guides of the X-axis and R-axis transmission mechanisms are located on both sides of the bending machine, resulting in a large span and reduced overall transmission structure accuracy; at the same time, the traditional transmission structure has low synchronization and overall stability. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the linear guide rails of the X-axis and R-axis transmission mechanism of the traditional back gauge are located on both sides of the bending machine, with a large span, which leads to a reduction in the overall transmission structure accuracy; at the same time, the traditional transmission structure has low synchronization and overall stability.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a mini back gauge for bending machines, including an X-axis mounting plate and an R-axis mounting plate. A Z-axis square tube is provided on the upper surface of the X-axis mounting plate. An X-axis ball screw and an X-axis linear guide for controlling the translation of the Z-axis square tube are movably mounted on the upper surface of the X-axis mounting plate. An auxiliary support is installed between the lower surface of the X-axis mounting plate and the back of the R-axis mounting plate. A back gauge finger is mounted on the upper end of the Z-axis square tube through the Z-axis linear guide. An X-axis drive servo motor for controlling the X-axis ball screw is installed on the inner side of the R-axis mounting plate. An R-axis drive drive gear is installed on the outer surface of the R-axis mounting plate.

[0005] The back of the R-axis mounting plate is fixedly fitted with an R-axis drive servo motor for controlling the R-axis drive drive gear.

[0006] The output end of the X-axis drive servo motor and the input end of the X-axis ball screw are connected by the X-axis drive synchronous belt on the X-axis main drive synchronous belt pulley.

[0007] The upper limit switch and the lower limit switch of the R-axis drive are fixedly installed on one side of the back of the R-axis mounting plate.

[0008] An R-axis slider is fixedly mounted on the outer side of the R-axis mounting plate.

[0009] The lower end of the Z-axis square tube is fixedly equipped with an X-axis transmission ball screw nut that cooperates with the X-axis ball screw and an X-axis slider that cooperates with the X-axis linear guide.

[0010] The beneficial effects of this utility model are:

[0011] (1) The mini back gauge for bending machine of this utility model uses linear guide rail and ball screw for transmission, which greatly improves the transmission accuracy.

[0012] (2) Setting auxiliary supports between the lower surface of the X-axis mounting plate and the back of the R-axis mounting plate can improve the overall structural stability. Attached Figure Description

[0020] Figure 1 , Figure 2 , Figure 3 and Figure 4 The mini back gauge for bending machines shown includes an X-axis mounting plate 1 and an R-axis mounting plate 2. A Z-axis square tube 3 is provided on the upper surface of the X-axis mounting plate 1. An X-axis ball screw 4 and an X-axis linear guide 5 for controlling the translation of the Z-axis square tube 3 are movably mounted on the upper surface of the X-axis mounting plate 1. An auxiliary support 6 is installed between the lower surface of the X-axis mounting plate 1 and the back of the R-axis mounting plate 2. A back gauge finger 8 is mounted on the upper end of the Z-axis square tube 3 through the Z-axis linear guide 7. An X-axis drive servo motor 9 for controlling the X-axis ball screw 4 is installed on the inner side of the R-axis mounting plate 2. An R-axis drive drive gear 10 is installed on the outer surface of the R-axis mounting plate 2.

[0021] The back of the R-axis mounting plate 2 is fixedly fitted with an R-axis drive servo motor 11 for controlling the R-axis drive drive gear 10.

[0022] The output end of the X-axis servo motor 9 and the input end of the X-axis ball screw 4 are connected by the X-axis drive synchronous belt 13 on the X-axis main drive synchronous belt pulley 12.

[0023] The upper limit switch 14 and the lower limit switch 15 of the R-axis drive are fixedly installed on one side of the back of the R-axis mounting plate 2.

[0024] The R-axis slider 16 is fixedly mounted on the outer side of the R-axis mounting plate 2.

[0025] The overall structure is mounted on the lower beam of the bending machine via an R-axis linear guide and an R-axis drive rack. The R-axis slider 16 and the R-axis linear guide are in linear rolling contact, and the R-axis drive drive gear 10 meshes with the R-axis drive rack.

[0026] The lower end of the Z-axis square tube 3 is fixedly equipped with an X-axis transmission ball screw nut 17 that cooperates with the X-axis ball screw 4 and an X-axis slider 18 that cooperates with the X-axis linear guide 5.

[0027] Function: The R-axis servo motor 11 drives the R-axis drive gear 10 to rotate. The R-axis drive gear 10 meshes with the R-axis drive rack. The R-axis mounting plate 2 is connected to the R-axis linear guide 16 via the R-axis slider 16, allowing for linear motion in the R-axis direction. The X-axis servo motor 9 drives the X-axis main drive synchronous pulley 12 to rotate, thereby synchronously driving the X-axis ball screw 4 to rotate. The X-axis ball screw 4 and the X-axis drive ball screw nut 17 perform rolling helical motion. The Z-axis square tube 3 moves linearly in the X-axis direction via the X-axis linear guide 5 and the X-axis slider 18. Specific control is achieved by the PLC controlling the R-axis servo motor driver to drive the R-axis servo motor 11 to rotate. The R-axis drive gear 10, in conjunction with the R-axis drive rack, drives the R-axis mounting plate 2 to move up and down in the R-axis direction, thus realizing the vertical movement of the entire back gauge mechanism. The R-axis drive upper limit switch 14 and R-axis drive lower limit switch 15 control the limits of the R-axis vertical movement. The PLC controls the X-axis servo motor driver to drive the X-axis transmission servo motor 9 to rotate. The X-axis main transmission synchronous belt pulley 13 and the X-axis transmission synchronous belt 12 drive the X-axis ball screw 4 to rotate. The X-axis ball screw 4, in conjunction with the X-axis transmission ball screw nut 17, rotates. The X-axis linear guide rail 5 and the X-axis slider 18 drive the Z-axis square tube 3 to move in the X-axis direction, thereby realizing the back gauge mechanism to move back and forth.
