Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a bending machine frame and a bending machine. Background Art

[0002] The bending machine is a widely used bending machine that has long been hydraulically operated. It is an important equipment in sheet metal processing and plays a decisive role in product quality, processing efficiency and precision. The bending machine frame is the main structural part of the bending machine, bearing the weight of each component of the bending machine and bearing the huge pressure generated during the bending process.

[0003] The existing Chinese patent with announcement number CN220837328U discloses a sheet metal bending machine, which relates to the technical field of bending machines and includes a first bending machine body and a second bending machine body, wherein the front surface of the first bending machine body is provided with a control panel. In the utility model, when bending a long workpiece, the first bending machine body and the second bending machine body are placed side by side. The control line of the first bending machine body and the second bending machine body can be connected by the setting of the control panel. After the bending knife and the bending die are matched with the first bending machine body and the second bending machine body to complete the installation, the first frame and the second frame are controlled by the control panel to move downward at the same time, and cooperate with the bending die to complete the bending process of the long workpiece. This solves the problem that the bending machine cannot be used when bending a long workpiece is required, and the practicality is poor.

[0004] When the bending machine under the above scheme and the existing technology processes larger plates, the plates may bend and deform, so several workers are required to hold the plates at the same time. The plates will rotate when being bent, and there is no support and fixing device under the plates. The plates will rotate at will or be deformed and damaged. There are sharp corners around the plates and they are not protected. It is easy to cause scratches to the processing personnel when bending and rotating. There is a lack of corresponding structure here, which needs to be improved and optimized. Utility Model Content

A group of auxiliary traction units are provided at both outer ends of the bending machine frame 1. One end of the support plate 10 is fixedly connected to multiple groups of first rotating shafts 9. The first rotating shaft 9 is plugged and connected to the shaft ring 8. The shaft ring 8 is fixedly connected to the front end of the bending die 2. A group of auxiliary limit clamping units are provided at each end above the support plate 10.

[0026] A bending machine comprises a bending machine frame.

[0027] During actual use, when the product is placed on the support plate 10, the auxiliary limit clamping units at both ends of the support plate 10 press and fix the plate. When the bending knife 4 is pressed down, the plate 20 bends and rotates. At the same time, the traction ropes 14 on both sides of the bending knife 4 pull the support plate 10, and the support plate 10 rotates through the first rotating shaft 9 in the shaft ring 8, ensuring that the plate 20 is always supported by the support plate 10 and fixed by the auxiliary limit clamping unit.

Both ends of the connecting plate 194 are fixedly connected to a limiting column 192, and the limiting column 192 is movably plugged into the clamping plate 193 through the movable circular hole 196. The lower end of the limiting column 192 is fixedly connected to the slider 191, and the lower end of the middle of the connecting plate 194 is fixedly connected to two sets of connecting springs 1 95; the bottom end of the adjusting bolt 197 is tightly attached to the upper end of the clamping plate 193, the limiting column 192 is symmetrically connected to the two ends of the connecting plate 194, the connecting spring 195 is symmetrically connected to the lower end of the clamping plate 193, and the threaded hole 198 is provided in the middle of the connecting plate 194; the outer side of the upper end surface of the support plate 10 is provided with a first slide groove 15 and a second slide groove 16, and the inner side of the upper end surface of the support plate 10 is provided with a third slide groove 17 and a fourth slide groove 18, both ends of the inside of the first slide groove 15 are clamped with a limiting column 192, and both ends of the inside of the second slide groove 16 are clamped with another limiting column 192, both ends of the third slide groove 17 are slidably connected to a connecting spring 195, and both ends of the fourth slide groove 18 are slidably connected to another connecting spring 195.

[0029] During actual use, the processed plate 20 is placed on the support plate 10. For plates 20 of different sizes, the turntable 199 is pushed to drive the slider 191 to slide in the first slide groove 15 and the second slide groove 16, and the connecting spring 195 slides in the third slide groove 17 and the fourth slide groove 18. When it moves to the position of the plate 20, the limiting column 192 presses against the plate 20. At this time, the turntable 199 is rotated to drive the adjusting bolt 197 to press down the clamping plate 193 to limit and fix the plate 20. When the plate 20 is processed, the turntable 199 is rotated to drive the adjusting bolt 197 to move upward, and the connecting spring 195 is reset to drive the clamping plate 193 to reset.

[0030] Embodiment three; a plurality of groups of brackets 6 are fixedly connected to the front end of the bending machine frame 1, and a rubber pad 7 is fixedly connected to each of the two ends of the upper surface of the bracket 6. The upper surface of the rubber pad 7 is tightly attached to the lower surface of the support plate 10 when the support plate 10 is in a horizontal state; the auxiliary traction unit includes a first column 11, a second rotating shaft 12, a second column 13, and a traction rope 14; the first column 11 is fixedly connected to the outer sides of the bending knife 4, the second rotating shaft 12 is connected to the upper ends of both sides of the bending machine frame 1, the second column 13 is fixedly connected to both ends of the support plate 10, one end of the traction rope 14 is fixedly connected to the first column 11, one end of the traction rope 14 is fixedly connected to the second column 13, and the middle part of the traction rope 14 is slidably connected to the second rotating shaft 12.

[0031] During actual use, when the plate 20 is placed on the support plate 10 for processing, the bending knife 4 is pressed down to drive the traction rope 14 to drive the support plate 10 to rotate as the plate 20 bends and rotates. When the processing is completed, the bending knife 4 moves up, the traction rope 14 relaxes, and the support plate 10 falls back and resets. The support plate 10 falls back on the rubber pad 7 on the bracket 6, which plays a buffering role, reducing noise and damage to the support plate 10 and the plate 20.
