Description

Technical Field

[0001] This utility model relates to the technical field of tent processing equipment, specifically to a pipe bending machine for tent processing. Background Technology

[0002] During the tent manufacturing process, the tubing supporting the tent needs to be bent to meet the structural installation requirements of different parts of the tent.

[0003] Existing pipe bending equipment has certain limitations in use. On the one hand, it makes the pipes prone to deviation during the bending process, affecting the bending accuracy. On the other hand, it cannot flexibly adjust the bending angle of the pipes according to processing requirements, resulting in a narrow range of applications. Furthermore, it lacks buffer protection during the bending process, which can easily damage the pipes and increase production costs.

[0004] To solve the above problems, this utility model proposes a pipe bending machine for tent processing. Utility Model Content

[0005] This utility model aims to solve the above-mentioned technical problems by providing a pipe bending machine for tent processing.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: A pipe bending machine for tent processing includes a connecting frame, the connecting frame including an upper top plate and a lower bottom plate, connecting columns are installed around the upper top plate and the lower bottom plate, and baffles are installed opposite each other on the lower bottom plate; A feeding mechanism for placing pipes is installed between the two baffles; The upper top plate is equipped with a drive mechanism for bending the pipe. The lower base plate, located directly below the feeding mechanism, is equipped with a limiting device for restricting the bending angle of the pipe.

[0007] As a further embodiment of this utility model: the feeding mechanism includes a fixed column installed between two baffles, a movable plate rotatably connected to the outer side of the fixed column, and an adjusting spring installed between the opposite sides of the two movable plates and the lower base plate.

[0008] As a further improvement of this invention: the opposing surfaces of the two movable plates are rounded, and the adjusting springs are arranged in two sets at an angle. The rounded structure can prevent scratches from occurring when the pipe moves with the movable plates, and the two sets of angled adjusting springs can provide more balanced support for the movable plates, enhancing stability.

[0009] As a further improvement of this invention: Each of the two movable plates has a placement groove at its upper end for use with the pipe, and a through hole in the middle of the two movable plates for use with the fixing post. The placement groove can position the pipe and prevent it from shifting laterally during feeding and bending, while the through hole ensures that the movable plate can rotate flexibly around the fixing post.

[0010] As a further improvement of this invention: the driving mechanism includes a stepping screw threadedly connected to the top plate and a stop frame movably connected to the lower end of the stepping screw. Guide tubes are slidably installed on the outer sides of the four sets of connecting columns, and the guide tubes are connected to the stop frame. A stop rod for bending the pipe is installed on the stop frame. The stepping screw can precisely control the descent distance of the stop frame, and the guide tubes ensure that the stop frame remains stable during descent, preventing the stop rod from shifting and affecting the bending accuracy.

[0011] As a further improvement of this utility model: the limiting device includes a threaded pipe fixedly connected to the lower base plate and a bolt internally threaded to the threaded pipe. A buffer spring is installed on the outer side of the threaded pipe and on the lower base plate, and a buffer block is installed on the buffer spring to abut against the bending point of the pipe. The initial height of the buffer block can be adjusted by rotating the bolt, thereby controlling the maximum bending angle of the pipe. The buffer spring can play a buffering role during the bending process of the pipe, preventing the pipe from being damaged due to excessive force.

[0012] As a further improvement of this invention, the buffer block is located directly below the placement groove. This positioning ensures that the buffer block acts precisely on the bending point of the pipe, guaranteeing accurate control of the bending angle.

[0013] With the above structure, this utility model has the following advantages: The feeding mechanism of this invention, through the cooperation of a movable plate, an adjusting spring, and a placement groove, can position the pipe, effectively preventing the pipe from shifting during processing and improving the stability of the pipe placement.

[0014] The driving mechanism of this invention utilizes a stepping screw and a guide tube to precisely control the downward stroke of the stop rod, ensuring uniform force and accurate positioning during the bending process of the tube, thereby improving bending accuracy.

[0015] The limiting device of this utility model changes the final position of the compression buffer block of the bent pipe by adjusting the height of the bolt, which facilitates flexible adjustment of the bending angle of the pipe and adapts to the processing needs of tent pipes of different specifications, thus enhancing the applicability of the equipment.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] The present invention will now be described in further detail in conjunction with the full text.

[0023] Combined with appendix Figures 1-3In this embodiment of the present invention, a pipe bending machine for tent processing includes a connecting frame 1. The connecting frame 1 is composed of an upper top plate 101, a lower bottom plate 102 and a connecting column 103. The connecting column 103 is installed around the upper top plate 101 and the lower bottom plate 102 for fixing the upper top plate 101 and the lower bottom plate 102. A baffle 104 is installed on the lower bottom plate 102 to provide installation support for the feeding mechanism 2.

[0024] In specific implementation of this utility model, such as Figure 1 and Figure 2 As shown, a feeding mechanism 2 is installed between the two baffles 104. The feeding mechanism 2 includes a fixed column 201, a movable plate 202, and an adjusting spring 203. The fixed column 201 is installed opposite to the two baffles 104. The movable plate 202 is rotatably connected to the outside of the fixed column 201. The adjusting spring 203 is installed between the back of the movable plate 202 and the lower base plate 102. In use, the pipe is placed in the placement groove 204 at the upper end of the two movable plates 202. The driving mechanism 3 bends the pipe downward, thereby pushing the movable plate 202 to rotate on the fixed column 201. This causes the two movable plates 202 to rotate, and the adjusting spring 203 is stretched under force. The two movable plates 202 can protect the pipe during bending and achieve stable feeding of the pipe.

[0025] In specific implementation of this utility model, such as Figure 1 and Figure 2 As shown, a drive mechanism 3 is installed on the upper top plate 101. The drive mechanism 3 includes a stepping screw 301, a stop frame 302, a guide tube 303, and a stop rod 304. The stepping screw 301 is threadedly connected to the upper top plate 101. A threaded cap can be provided on the upper top plate 101. The stepping screw 301 is threaded through the upper top plate 101 through the threaded cap. The stop frame 302 is movably connected to the lower end of the stepping screw 301. The lower end of the stepping screw 301 can be connected to the stop frame 302 through a bearing, so that the rotation drives the stop frame 302 to move. Alternatively, the stepping screw 301 and the stop frame 302 can be movably connected. The stepping screw 301 can directly abut against the stop frame 302, thereby driving the stop rod 304, which abuts against the lower end of the stop frame 302, to descend and push the pipe, thereby achieving pipe bending. The guide tube 303 is slidably installed on the outside of the connecting column 103 and connected to the stop frame 302. The stop rod 304 is installed on the stop frame 302. When the drive mechanism 3 is started, the stepping screw 301 is rotated, which drives the support frame 302 to descend along the guide tube 303. The support rod 304 then descends and pushes the pipe to achieve pipe bending.

[0026] In specific implementation of this utility model, such as Figure 1 and Figure 2As shown, a limiting device 4 is installed on the lower base plate 102 and directly below the feeding mechanism 2. The limiting device 4 includes a threaded pipe 401, a bolt 402, a buffer spring 403, and a buffer block 404. The threaded pipe 401 is fixedly connected to the lower base plate 102, and the bolt 402 is threadedly connected to the threaded pipe 401. The buffer spring 403 is installed on the outside of the threaded pipe 401 and on the lower base plate 102, and the buffer block 404 is installed on the buffer spring 403. According to the required bending angle, the bolt 402 is rotated to adjust the abutment height of the buffer block 404 after being subjected to force. During the pipe bending process, the buffer block 404 will abut against the bending point of the pipe, limiting the maximum bending angle of the pipe. The stiffness coefficient of the buffer spring 403 is 50-100 N / mm, and the buffer spring 403 plays a buffering and protective role. The buffer block 404 is made of polyurethane with a Shore hardness of 60-70D. It has a certain supporting strength (can withstand 500-1000N of pressure without deformation) and can make flexible contact with the pipe, further reducing the risk of pipe damage.

[0027] During the pipe bending process, the buffer block 404 is pressed against, and the buffer spring 403 is compressed, thus continuing the bending until it presses against the rotating bolt 402, thereby achieving the required bending angle. Specifically, the height of the rotating bolt 402 on the threaded pipe 401 is used to adjust the bending angle. Suitable parameters can be obtained through a large number of tests. Specific parameters can be further verified through a large number of experiments, which will not be elaborated again. Furthermore, the height of the rotating bolt 402 can be measured with an external ruler while rotating the bolt to ensure that the height of the rotating bolt 402 is within acceptable limits.

[0028] In addition, the opposite surfaces of the two movable plates 202 are rounded to prevent scratching the pipe; the adjusting springs 203 are set in two tilted positions to provide a more balanced stabilizing force; the buffer block 404 is located directly below the placement groove 204 to ensure precise application to the pipe bending point.

[0029] The working principle of this utility model: First, adjust the abutment height of the buffer block 404 after being stressed by rotating bolt 402 according to the required bending angle. Place the pipe in the placement slot 204 at the upper end of the two movable plates 202. The rotating stepping screw 301 of the drive mechanism 3 drives the abutment 302 to descend along the guide tube 303. The abutment rod 304 descends accordingly and pushes the pipe. The pipe is bent downwards, which pushes the movable plate 202 to rotate on the fixed column 201. This causes the two movable plates 202 to rotate, and the adjusting spring 203 is stretched. The two movable plates 202 can protect the pipe during bending and achieve stable feeding of the pipe. During the bending process, the pipe is pressed against the buffer block 404, which compresses the buffer spring 403, thus continuing to bend until it presses against the rotating bolt 402, thereby achieving the required bending angle.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
