Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a metal processing bending machine. Background Art

[0002] Metalworking is the process of processing and treating metal materials through various physical and chemical methods to create desired parts, products, or structures. A press brake is a machine specifically designed to shape metal materials. By applying pressure, the metal is bent using a specific die and bending angle to create a product that meets the design requirements.

[0003] However, existing bending machines generally place the workpiece on the surface of the workbench, which is prone to unstable placement. Especially when processing long or heavy workpieces, the workpiece may fall or move, thereby affecting the bending accuracy. Moreover, the toppling of the workpiece will cause safety hazards during operation and increase the risk to the operator.

[0004] Therefore, those skilled in the art provide a metal processing bending machine to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a metal processing bending machine. The utility model can place a workpiece in a placement groove to prevent the workpiece from tipping over.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A metal processing bending machine includes a base plate, wherein support feet are fixedly provided at the four corners of the lower end of the base plate, a slide groove is provided at the middle of the upper end of the base plate, a fixed plate is fixedly provided at one side of the upper end of the base plate, a hydraulic telescopic rod is fixedly provided at one side of the fixed plate, a workpiece placement mechanism is fixedly provided at the front end of the hydraulic telescopic rod, and a bending mechanism is fixedly provided at the other side of the upper end of the base plate.

[0008] Furthermore, the workpiece placement mechanism includes a connecting plate, a placement box is fixedly provided on one side of the connecting plate by bolts, placement grooves are provided at the upper end and the inner bottom end of the placement box, and a slider is fixedly provided at the lower end of the placement box.

[0009] Furthermore, the connecting plate is fixedly connected to the hydraulic telescopic rod, and the sliding block is slidably arranged at the inner end of the sliding groove.

[0010] Furthermore, the placement box is movably arranged on the upper end of the bottom plate, and the placement grooves are all opened on the upper end of the slide groove.

[0011] Furthermore, the bending mechanism includes a limit box and a bending block, a plurality of slots are provided at the front and rear ends of the inner side of the limit box, a plurality of the slots are fixedly provided with a clamping column at one end opposite to each other, a plurality of springs are provided at the front and rear ends of the outer side of the limit box, a movable slot is provided on one side of the limit box, and a connecting block is fixedly provided at the lower end of the bending block.

[0012] Furthermore, the limit box is fixedly arranged on the other side of the upper end of the bottom plate, and the bending block is movably arranged on the inner end of the limit box.

[0013] Furthermore, a plurality of the springs are fixedly sleeved on the outer ends of the clamping columns, and the connecting block is movably arranged between the plurality of clamping columns.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model proposes a metal processing bending machine. After the hydraulic telescopic rod starts to operate, the workpiece to be bent needs to be placed on the inner end of the placement slot close to the bending mechanism. Since the bending mechanism is fixed in one position, the workpiece will bend under the thrust of the hydraulic telescopic rod, which can achieve efficient processing, reduce preparation time, and improve overall production efficiency. At the same time, the connecting plate and the placement box are connected by bolts. This design allows the placement box to be replaced to adapt to placement slots of different specifications. Different types of workpieces can be effectively bent, ensuring production flexibility and efficiency.

[0016] 2. The utility model proposes a metal processing bending machine. When adjusting the position of the bending block, it is first necessary to pull the clamping column backward so that the connecting block can pass smoothly. The connecting block will be fixed between the two clamping columns, thereby effectively preventing the displacement of the bending block during the bending process. At the same time, the width of the movable groove just allows the slider to pass through, and the width of the connecting block is greater than the width of the slider. This design ensures that the bending block will not fall out from the inner end of the limit box, and the slider can still smoothly enter the inner end of the limit box, which can effectively maintain the required positioning and stability, and ensure precision and safety during the processing.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1 , an embodiment provided by the utility model:

[0026] A metal processing bending machine includes a base plate 1, support legs 2 are fixedly provided at the four corners of the lower end of the base plate 1, a slide groove 6 is provided at the middle of the upper end of the base plate 1, a fixed plate 3 is fixedly provided on one side of the upper end of the base plate 1, a hydraulic telescopic rod 4 is fixedly provided on one side of the fixed plate 3, a workpiece placement mechanism 5 is fixedly provided at the front end of the hydraulic telescopic rod 4, and a bending mechanism 7 is fixedly provided on the other side of the upper end of the base plate 1.

[0027] Specifically, after the hydraulic telescopic rod 4 starts to operate, the workpiece placement mechanism 5 will move toward the bending mechanism 7, and then the bending mechanism 7 can bend the workpiece.

[0028] Reference Figure 2 、 Figure 3 The workpiece placement mechanism 5 includes a connecting plate 501, a placement box 502 is fixed to one side of the connecting plate 501 by bolts, a placement groove 503 is opened at the upper end and the inner bottom end of the placement box 502, and a slider 504 is fixed to the lower end of the placement box 502;

[0029] The connecting plate 501 is fixedly connected to the hydraulic telescopic rod 4, and the slider 504 is slidably arranged at the inner end of the slide groove 6;

[0030] The placement box 502 is movably arranged at the upper end of the bottom plate 1 , and the placement grooves 503 are all opened at the upper end of the sliding groove 6 .

[0031] Specifically, after the hydraulic telescopic rod 4 starts to operate, the workpiece to be bent needs to be placed on the inner end of the placement slot 503 near the bending mechanism 7. Since the bending mechanism 7 is fixed in one position, the workpiece will bend under the thrust of the hydraulic telescopic rod 4, which can achieve efficient processing, reduce preparation time, and improve overall production efficiency. At the same time, the connecting plate 501 is connected to the placement box 502 by bolts. This design allows the placement box 502 to be replaced to adapt to placement slots 503 of different specifications. Different types of workpieces can be effectively bent to ensure production flexibility and efficiency.

[0032] Reference Figure 4 、 Figure 5 The bending mechanism 7 includes a limit box 701 and a bending block 706. The limit box 701 has a plurality of slots 702 at the front and rear ends thereof. A plurality of slots 702 are fixedly provided with a clamping column 703 at one end opposite to each other. The limit box 701 has a plurality of springs 704 at the front and rear ends thereof. A movable slot 705 is provided on one side of the limit box 701. A connecting block 707 is fixedly provided at the lower end of the bending block 706.

[0033] The limit box 701 is fixedly arranged on the other side of the upper end of the bottom plate 1, and the bending block 706 is movably arranged on the inner end of the limit box 701;

[0034] A plurality of springs 704 are fixedly sleeved on the outer ends of the clamping columns 703 , and the connecting block 707 is movably arranged between the plurality of clamping columns 703 .

[0035] Specifically, when adjusting the position of the bending block 706, it is first necessary to pull the clamping column 703 backward so that the connecting block 707 can pass through smoothly. The connecting block 707 will be fixed between the two clamping columns 703, thereby effectively preventing the displacement of the bending block 706 during the bending process. At the same time, the width of the movable groove 705 just allows the slider 504 to pass through, and the width of the connecting block 707 is greater than the width of the slider 504. This design ensures that the bending block 706 will not fall out from the inner end of the limit box 701, and the slider 504 can still smoothly enter the inner end of the limit box 701, which can effectively maintain the required positioning and stability, and ensure accuracy and safety during the processing.

[0036] Working principle: After the hydraulic telescopic rod 4 starts to operate, the workpiece to be bent needs to be placed on the inner end of the placement slot 503 near the bending mechanism 7. Since the bending mechanism 7 is fixed in one position, the workpiece will bend under the thrust of the hydraulic telescopic rod 4. At the same time, the connecting plate 501 and the placement box 502 are connected by bolts. This design allows the placement box 502 to be replaced to adapt to placement slots 503 of different specifications.

[0037] Secondly, when adjusting the position of the bending block 706, it is first necessary to pull the clamping column 703 backward so that the connecting block 707 can pass through smoothly. The connecting block 707 will be fixed between the two clamping columns 703, thereby effectively preventing the displacement of the bending block 706 during the bending process. At the same time, the width of the movable groove 705 just allows the slider 504 to pass through, and the width of the connecting block 707 is greater than the width of the slider 504. This design ensures that the bending block 706 will not fall out from the inner end of the limit box 701, and the slider 504 can still smoothly enter the inner end of the limit box 701, which can effectively maintain the required positioning and stability, and ensure accuracy and safety during the processing.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
