Description

Technical Field

[0001] The utility model relates to the technical field of bending equipment, in particular to a bending equipment for processing arc-shaped plates. Background Art

[0002] The bending process of arc-shaped plates refers to the process of bending metal plates into arcs or curved surfaces, which is very common in fields such as construction, automotive, aerospace, and manufacturing, and is used to manufacture components such as domes, curved guardrails, and vehicle body parts.

[0003] Currently, for general plate bending equipment, after frequent use, the pressing module will be damaged. Therefore, during use, it is necessary to regularly maintain it. However, the installation method of the pressing module in the existing bending equipment is relatively cumbersome, making it troublesome to disassemble when needed, and also troublesome to install after maintenance, which affects work efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a bending equipment for processing arc-shaped plates, which makes the disassembly work of the bending press block faster and improves work efficiency.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A workbench, on the top of which the left and right sides of the workbench are fixedly connected with concave frames. The inner wall of the top of the concave frames is fixedly connected with hydraulic rods. The driving end of the hydraulic rods is fixedly connected with a connecting plate. The bottom of the connecting plate is provided with a bending press block for bending the plate. The bending press block is connected with the connecting plate through an elastic component;

[0008] A limiting frame, which is respectively located on the front and rear sides of the inner wall of the concave frame. The bottom end of the limiting frame is fixedly connected to the top of the workbench. The opposite ends of the limiting frame are provided with sliding grooves. The opposite sides of the limiting frame are provided with a pressing groove table for cooperating with the bending press block to realize plate bending. The pressing groove table is connected with the limiting frame through a clamping component.

[0009] Further, the elastic component includes plugs fixedly connected to the left and right sides of the top of the bending press block. The upper inner wall of the opposite ends of the plugs is slidably connected with clamping blocks. The opposite ends of the clamping blocks are fixedly connected with springs, and one end of the springs is fixedly connected to the inner wall of the plugs.

[0010] Further, the distance between the opposite sides of the plugs is smaller than the distance between the opposite sides of the hydraulic rods, and the distance from the bottom end of the clamping block to the top of the bending press block is the same as the thickness of the plug.

[0011] Furthermore, slots are provided on the left and right sides of the inner wall of the connecting plate, and the shape of the top of the insertion block fits the shape of the inner wall of the slot.

[0012] Furthermore, the clamping component includes a number of limiting bolts fixedly connected to the left and right ends of the pressing groove platform and a transfer block rotatably connected to the left and right ends of the limiting frame. The limiting bolts are sequentially located on one side of the transfer block. A notch is provided at the top of the limiting bolt, and the shape of the outer wall on one side of the transfer block fits the shape of the inner wall of the notch.

[0013] Furthermore, insertion strips are fixedly connected to the front and rear ends of the pressing groove platform, and the outer wall of the insertion strip is embedded in the inner wall of the sliding groove.

[0014] Furthermore, a first baffle is fixedly connected to the opposite sides of the top of the limiting frame, and second baffles are fixedly connected to the left and right sides of the top of the limiting frame.

[0015] The utility model has the following beneficial effects:

[0016] 1. In the utility model, by pressing the two side clamping blocks, when the clamping blocks are completely retracted into the insertion blocks, the limit on the connecting plate is released. The insertion blocks are pulled out downward from the slots, so that the bending pressing block is separated from the connecting plate for separate treatment, thereby making the disassembly of the bending pressing block faster and improving work efficiency.

[0017] 2. In the utility model, by reversing the transfer block, the bottom of one end is disengaged from the notch, thereby releasing the limit on the pressing groove platform. Then the pressing groove platform is pulled out from between the limiting frames, which can facilitate the maintenance of the pressing groove platform and improve its service life.

[0028] Further explanation, first baffles 10 are fixedly connected to the opposite sides of the top of the limiting frame 7, second baffles 11 are fixedly connected to the left and right sides of the top of the limiting frame 7, the distance between the opposite sides of the insertion block 6 is smaller than the distance between the opposite sides of the hydraulic rod 3, refer to Figure 5 , the distance from the bottom end of the clamping block 16 to the top of the bending press block 5 is the same as the thickness of the insertion block 6, slots 17 are opened on the left and right sides of the inner wall of the connecting plate 4, and the shape of the top of the insertion block 6 fits the shape of the inner wall of the slot 17.

[0029] Specifically, the sheet is buckled between the first baffle 10 and the second baffle 11 for limiting. Then, the hydraulic rod 3 is activated to push the bending press block 5 downward, pressing the sheet into the inner wall of the pressing groove table 8 to bend the sheet into an arc-shaped plate.

[0030] When the bending press block 5 is damaged or needs maintenance, by pressing the two side blocks 16, the blocks 16 slide into the insertion block 6 and compress the spring 18. When the blocks 16 are completely retracted into the insertion block 6, the limit on the connecting plate 4 is released.
