Description

Technical Field

[0001] This utility model relates to the field of hoop processing technology, and more specifically, to a bending device for hoop processing. Background Technology

[0002] Clamp bending is a common processing method in the fields of machinery manufacturing and metal processing. It is mainly used for connecting and fixing metal materials such as pipes and bars. Clamps have high connection strength and stability and are widely used in industries such as construction, bridges, automobiles, ships, and chemicals.

[0003] A search revealed that Chinese patent application number 201821547128.X discloses a C-shaped clamp processing device, comprising a base plate, a rotating device, and a bending device. The base plate has the rotating device and the bending device positioned opposite each other. A sheet material is clamped on the rotating device and bent into a C-shaped clamp under the pressure of the bending device. The rotating device includes a base fixed to the base plate, a turntable on top of the base, and a bending device on the turntable. A pressure plate is provided on the side wall of the bending device. The bending device includes a column, a screw, a handle, and a pressure roller. The column is fixed to the base, the screw passes through the column and is perpendicular to the rotating device, a pressure roller frame is provided at the end of the screw facing the rotating device, and a pressure roller is provided on the pressure roller frame. A handle is provided at the end of the screw away from the rotating device. However, this device still has the following drawbacks:

[0004] (1) In the above patent documents, a bending device is used as the basic mold for bending the clamp. However, since the diameter of the bending device is fixed, it is necessary to replace the bending device with a different diameter when bending clamps of different sizes, which increases the cost of using the device and the labor intensity of the user.

[0005] (2) In the above patent documents, a pressure plate is used to clamp and fix the clamp. After the clamp is processed, the user needs to manually disassemble the pressure plate and replace the clamp to be processed, which increases the complexity of the operation and reduces the processing efficiency of the clamp.

[0006] Therefore, we have made improvements to this by proposing a bending device for clamp processing. Utility Model Content

[0007] The purpose of this utility model is to address the current practice of using a bending device as the basic mold for bending clamps. However, because the diameter of the bending device is fixed, it is necessary to change to a bending device of different diameters when bending clamps of different sizes, which increases the cost of using the device and the labor intensity of the user. Using a pressure plate to clamp and fix the clamp requires the user to manually disassemble the pressure plate and replace the clamp to be processed after the clamp is processed, which increases the complexity of the operation and reduces the processing efficiency of the clamp.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A bending device for clamp processing includes a base, a positioning groove formed on the top wall of the base, and a bracket fixedly connected to the bottom wall of the base, and further includes:

[0010] The drive assembly is fixedly connected to the inner wall of the base and is used to output power for positioning and clamping the clamping component. The drive assembly includes a positioning motor fixedly connected to the inner wall of the base, a screw fixedly connected to the output end of the positioning motor, and a threaded sleeve threadedly connected to the outer wall of the screw.

[0011] The positioning component is slidably connected to the inner wall of the positioning groove and is used for positioning the clamp component.

[0012] The lifting assembly is fixedly connected to the inner wall of the base to accommodate clamp components of different widths;

[0013] The rotating component is rotatably connected to the top of the lifting component and is used to bend and shape the clamp component.

[0014] The bending assembly is rotatably connected to the top of the rotating assembly and is used to adjust the inner ring diameter of the clamp bending.

[0015] As a preferred technical solution of this utility model, the positioning component includes a positioning slide block slidably connected to the inner wall of the positioning groove, a positioning roller rotatably connected to the top wall of the positioning slide block, and a transmission rod rotatably connected to the bottom wall of the positioning slide block. The threaded sleeve drives the positioning slide block to move along the inner wall of the positioning groove through the transmission rod.

[0016] As a preferred technical solution of this utility model, the lifting assembly includes a limiting frame fixedly connected to the inner wall of the base, a lifting frame slidably connected to the outer wall of the limiting frame, a mounting seat fixedly connected to the top wall of the lifting frame, and a lifting hydraulic cylinder rotatably connected to the inner wall of the base. The lifting frame extends upward through the outer wall of the base, and the lifting hydraulic cylinder drives the lifting frame to move up and down along the outer wall of the limiting frame. The limiting frame, the lifting frame, and the lifting hydraulic cylinder are symmetrically distributed about the central axis of the base.

[0017] As a preferred technical solution of this utility model, the rotating assembly includes a rotating seat rotatably connected to the inner wall of the mounting base, a gear ring fixedly connected to the top wall of the rotating seat, a rotating motor fixedly connected to the inner wall of the mounting base, and a gear fixedly connected to the output end of the rotating motor. The rotating motor is symmetrically distributed about the central axis of the mounting base, and the gear meshes with the gear ring.

[0018] As a preferred technical solution of this utility model, the bending assembly includes a shaping groove formed on the top wall of the rotating seat, a shaping slide block slidably connected to the inner wall of the shaping groove, a support frame fixedly connected to the bottom wall of the shaping slide block, a shaping roller rotatably connected to the inner wall of the support frame, and a shaping hydraulic cylinder rotatably connected to the top wall of the rotating seat. The shaping hydraulic cylinders are symmetrically distributed about the central axis of the rotating seat, and the shaping hydraulic cylinders drive the shaping slide block to move along the inner wall of the shaping groove.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In the solution of this utility model:

[0021] 1. The positioning motor drives the screw to rotate, and the screw pushes the positioning slide to move a set distance along the inner wall of the positioning groove through the threaded sleeve and transmission rod. The spacing between the positioning rollers is adjusted. Then, the lifting hydraulic cylinder is controlled to make the shaping roller and the positioning roller at the same horizontal position. The shaping hydraulic cylinder is controlled to push the shaping slide and the shaping roller to bend the clamp, realizing the bending process of clamps with different inner diameters. This solves the problem that in the existing technology, a bending device is used as the basic mold for bending clamps. However, because the diameter of the bending device is fixed, it is necessary to change the bending device with different diameters when bending clamps of different sizes, which increases the cost of using the device and the labor intensity of the user.

[0022] 2. The positioning motor drives the screw to rotate, and the screw pushes the positioning slide to move and reset through the threaded sleeve and transmission rod. The lifting hydraulic cylinder is controlled to push the mounting seat and the shaping roller to move upward and reset. Then the processed clamp can be directly taken out. This device realizes automatic positioning, clamping and releasing of the clamp before and after bending. It solves the problem of the existing technology that uses a pressure plate to clamp and fix the clamp. After the clamp is processed, the user needs to manually remove the pressure plate and replace the clamp to be processed, which increases the cumbersome operation and reduces the processing efficiency of the clamp.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1 and Figure 4 As shown, this embodiment proposes a bending device for clamp processing, including a base 1, a positioning groove 12 formed on the top wall of the base 1, and a bracket 11 fixedly connected to the bottom wall of the base 1, and further including:

[0031] The drive assembly is fixedly connected to the inner wall of the base 1 and is used to output power for positioning and clamping the clamping component. The drive assembly includes a positioning motor 2 fixedly connected to the inner wall of the base 1, a screw 21 fixedly connected to the output end of the positioning motor 2, and a threaded sleeve 22 threadedly connected to the outer wall of the screw 21.

[0032] The positioning component is slidably connected to the inner wall of the positioning groove 12 and is used for positioning the clamp component.

[0033] The lifting assembly is fixedly connected to the inner wall of the base 1 to accommodate clamp components of different widths;

[0034] The rotating component is rotatably connected to the top of the lifting component and is used to bend and shape the clamp component.

[0035] The bending assembly is rotatably connected to the top of the rotating assembly and is used to adjust the inner ring diameter of the clamp bending.

[0036] The positioning motor 2 drives the screw 21 to rotate, and the screw 21 pushes the positioning slide 31 to move along the inner wall of the positioning slide groove 12 through the threaded sleeve 22 and the transmission rod 3.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the positioning component further includes a positioning slide 31 slidably connected to the inner wall of the positioning groove 12, a positioning roller 32 rotatably connected to the top wall of the positioning slide 31, and a transmission rod 3 rotatably connected to the bottom wall of the positioning slide 31. The threaded sleeve 22 drives the positioning slide 31 to move along the inner wall of the positioning groove 12 through the transmission rod 3. When the positioning slide 31 moves to a set distance, the distance between the positioning rollers 32 is adjusted to complete the adjustment of the inner diameter of the clamp to be bent.

[0038] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the lifting assembly further includes a limiting frame 4 fixedly connected to the inner wall of the base 1, a lifting frame 41 slidably connected to the outer wall of the limiting frame 4, a mounting seat 43 fixedly connected to the top wall of the lifting frame 41, and a lifting hydraulic cylinder 42 rotatably connected to the inner wall of the base 1. The lifting frame 41 extends upward through the outer wall of the base 1, and the lifting hydraulic cylinder 42 drives the lifting frame 41 to move up and down along the outer wall of the limiting frame 4. The limiting frame 4, the lifting frame 41, and the lifting hydraulic cylinder 42 are symmetrically distributed about the central axis of the base 1. The lifting hydraulic cylinder 42 is controlled to push the lifting frame 41 to move up and down along the outer wall of the limiting frame 4, so that the lifting frame 41 drives the mounting seat 43 to move downward. The mounting seat 43 drives the shaping roller 63 and the positioning roller 32 to be at the same horizontal position, thus completing the positioning of the clamp to be bent.

[0039] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the rotating assembly further includes a rotating seat 5 rotatably connected to the inner wall of the mounting base 43, a gear ring 51 fixedly connected to the top wall of the rotating seat 5, a rotating motor 52 fixedly connected to the inner wall of the mounting base 43, and a gear 53 fixedly connected to the output end of the rotating motor 52. The rotating motor 52 is symmetrically distributed about the central axis of the mounting base 43. The gear 53 meshes with the gear ring 51 to control the rotation of the rotating motor 52. The transmission motor drives the rotating seat 5 to rotate through the gear 53 and the gear ring 51. The rotating seat 5 drives the support frame 62 and the shaping roller 63 to rotate. Since the shaping roller 63 squeezes the clamp and the positioning roller 32 tightly, the shaping roller 63 and the positioning roller 32 cooperate to complete the bending work of the clamp with a specified inner diameter.

[0040] like Figure 2 , Figure 3 and Figure 4As shown, in a preferred embodiment, based on the above method, the bending assembly further includes a shaping groove 6 formed on the top wall of the rotating seat 5, a shaping slide 61 slidably connected to the inner wall of the shaping groove 6, a support frame 62 fixedly connected to the bottom wall of the shaping slide 61, a shaping roller 63 rotatably connected to the inner wall of the support frame 62, and a shaping hydraulic cylinder 64 rotatably connected to the top wall of the rotating seat 5. The shaping hydraulic cylinder 64 is symmetrically distributed about the central axis of the rotating seat 5. The shaping hydraulic cylinder 64 drives the shaping slide 61 to move along the inner wall of the shaping groove 6. The shaping hydraulic cylinder 64 pushes the shaping slide 61 to move along the inner wall of the shaping groove 6. The shaping slide 61 drives the support frame 62 and the shaping roller 63 to squeeze in the direction of the clamp. When the shaping roller 63 squeezes the clamp until it is tightly attached to the positioning roller 32.

[0041] Specifically, in use, the positioning motor 2 drives the screw 21 to rotate. The screw 21 pushes the positioning slide 31 along the inner wall of the positioning groove 12 through the threaded sleeve 22 and the transmission rod 3. When the positioning slide 31 moves to the set distance, the spacing between the positioning rollers 32 is adjusted to complete the adjustment of the inner diameter of the clamp to be bent. The clamp to be bent is placed between the set positioning rollers 32 to complete the preparation work before bending the clamp. The lifting hydraulic cylinder 42 is controlled to push the lifting frame 41 to move up and down along the outer wall of the limit frame 4, so that the lifting frame 41 drives the mounting base 43 to move downward. The mounting base 43 drives the shaping roller 63 to be at the same horizontal position as the positioning roller 32, completing the positioning of the clamp to be bent. The shaping hydraulic cylinder 64 is started to push the shaping slide 61. Moving along the inner wall of the shaping slide 6, the shaping slide 61 drives the support frame 62 and the shaping roller 63 to press towards the clamp. When the shaping roller 63 presses the clamp until it is tightly fitted with the positioning roller 32, the control motor 52 is turned. The transmission motor drives the rotating seat 5 to rotate through the gear 53 and the gear ring 51. The rotating seat 5 drives the support frame 62 and the shaping roller 63 to rotate. Because the shaping roller 63 presses the clamp tightly against the positioning roller 32, the shaping roller 63 and the positioning roller 32 cooperate to complete the bending work of the clamp with the specified inner diameter. After the clamp bending process is completed, the control motor 2 and the shaping hydraulic cylinder 64 are simultaneously controlled to reset the positioning roller 32 and the shaping roller 63. Then the processed clamp is directly taken out, and then the next round of processing is carried out.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
