Technical Field

[0001] This utility model relates to the technical field of support and guide accessories for bending machines, and in particular to a heavy-duty back gauge support and guide mechanism 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. Due to the excessive span and low overall rigidity of heavy-duty back gauges, the entire back gauge vibrates during movement, affecting its accuracy and service life. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the heavy-duty back gauge has an excessively large span and low overall rigidity, which causes the entire back gauge to vibrate during movement, affecting the accuracy and service life of the entire back gauge.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a heavy-duty back gauge support and guide mechanism for a bending machine, including a square tube for the R-axis of the bending machine, wherein an auxiliary support mechanism is fixedly installed on the square tube for the R-axis of the bending machine by means of internal hexagon screws, and the auxiliary support mechanism includes a main support frame, an auxiliary bracket, an auxiliary rotating seat, an auxiliary connecting rod, a bottom adjustment mechanism and auxiliary rollers.

[0005] The auxiliary bracket is welded and fixed at both ends to the outer surfaces of the longitudinal and transverse sections of the main support frame.

[0006] The auxiliary rotating seat is fixedly installed on the lower surface of the main support frame. The auxiliary connecting rod has an L-shaped structure and is movably assembled with the interior of the auxiliary rotating seat through an auxiliary mandrel.

[0007] The bottom adjustment mechanism includes an auxiliary adjustment screw, an adjustment nut, an auxiliary guide ring, and an auxiliary spring.

[0008] The upper end of the auxiliary adjusting screw is fixedly installed inside the horizontal section of the main support frame, the adjusting nut is threaded onto the auxiliary adjusting screw, and the auxiliary spring is sleeved on the outside of the auxiliary adjusting screw.

[0009] The auxiliary guide ring is fitted between the adjusting nut and the auxiliary spring.

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

[0011] (1) The heavy-duty back gauge support and guide mechanism for bending machines of this utility model has a simple structure and good stability;

[0012] (2) The clamping amount can be freely adjusted according to the situation, and the vibration of the entire back gauge is reduced during the movement, thereby improving the accuracy and service life of the entire back gauge. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Figure 1 , Figure 2 and Figure 3 The heavy-duty back gauge support and guide mechanism for the bending machine shown includes a square tube 1 for the R-axis of the bending machine. An auxiliary support mechanism is fixedly installed on the square tube 1 for the R-axis of the bending machine by hexagonal screws. The auxiliary support mechanism includes a main support frame 2, an auxiliary bracket 3, an auxiliary rotating seat 4, an auxiliary connecting rod 5, a bottom adjustment mechanism, and auxiliary rollers 6.

[0020] The auxiliary support is processed by welding and fixing its two ends to the outer surfaces of the longitudinal and transverse sections of the main support frame 2.

[0021] The auxiliary rotating seat 4 is fixedly installed on the lower surface of the main support frame 2. The auxiliary connecting rod 5 has an L-shaped structure and is movably assembled with the auxiliary rotating seat 4 through the auxiliary spindle.

[0022] The bottom adjustment mechanism includes an auxiliary adjustment screw 7, an adjustment nut 8, an auxiliary guide retaining ring 9, and an auxiliary spring 10.

[0023] The upper end of the auxiliary adjusting screw 7 is fixedly installed inside the horizontal section of the main support frame 2. The adjusting nut 8 is threaded onto the auxiliary adjusting screw 7, and the auxiliary spring 10 is fitted onto the outside of the auxiliary adjusting screw 7.

[0024] The auxiliary guide ring 9 is fitted between the adjusting nut 8 and the auxiliary spring 10.

[0025] The auxiliary connecting rod 5 rotates with the auxiliary rotating seat 4, and the stroke is controlled by the auxiliary adjusting screw 7. The auxiliary roller 6 rolls with the lower support steel pipe, and the clamping stroke of the auxiliary roller 6 is adjusted by the auxiliary adjusting screw 7. The adjusting nut 8 adjusts the clamping amount of the auxiliary spring 10 through the thread on the auxiliary adjusting screw 7, thereby controlling the pressure of the auxiliary roller 6 on the lower support steel pipe. This ensures that the reaction force on the square tube 1 of the R-axis of the bending machine is optimal.

[0026] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
