Description

Technical Field

[0001] The invention relates to the technical field of punching devices, and in particular to a spiral pipe seam punching device. Background Art

[0002] In the environmental protection industry, spiral pipes with holes can be used to build rainwater collection and drainage systems. During the production and processing of spiral pipes, a common requirement is to accurately punch holes on their surfaces, especially those with spiral inclined protrusions (forming spiral pipe seams). The design of these spiral pipe seams increases the complexity of the drilling operation, because the traditional single drill bit drilling method is inefficient and time-consuming when facing long pipe seams.

[0003] In order to improve efficiency, drilling equipment with multiple drill bits has appeared on the market. They can punch a row of holes on the spiral tube along the spiral trajectory at one time. The drilling task can be completed by simply rotating the spiral tube for one circle and moving it in the spiral direction. However, due to the large number of drill bits, they will form a significant thrust when acting on the spiral tube at the same time. This thrust may cause the spiral tube to deform if the material of the spiral tube is soft or the structure is not stable enough, thereby affecting the drilling accuracy and the overall quality of the spiral tube, and even causing damage.

[0004] To this end, the present invention provides a spiral pipe seam punching device that can solve the above-mentioned problem. Summary of the invention

[0031] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0032] Embodiment 1

[0033] like Figure 1-Figure 3 As shown, in this embodiment, a spiral tube seam punching device is provided, including a body 1, a pushing channel, a supporting unit and a punching mechanism. The pushing channel is a channel for the movement of the spiral tube, and the spiral tube can move in the pushing channel. Inside the pushing channel, a device dedicated to driving the movement of the pushing spiral tube is integrated. This device has the ability to enable the spiral tube to move flexibly in the channel, not only supports the smooth transmission of the spiral tube in a straight direction, but also can cause the spiral tube to move in a specific direction while rotating when punching holes along the spiral tube seam. This specific direction is consistent with the spiral direction of the spiral tube seam on the spiral tube.

[0034] The support unit is installed inside the pushing channel. The support unit can be inserted into the spiral tube. When the spiral tube enters the pushing channel, it will first be smoothly connected from one end of the support unit and tightly sleeved on the support unit. This support unit is designed inside the spiral tube. Its main function is to provide the necessary support force for the spiral tube and ensure that the spiral tube maintains a stable shape and structure during the pushing process.

[0035] The drilling mechanism includes a plurality of drill bits 8, which can move up and down inside the body 1. The drill bits 8 drill holes in the spiral tube during the downward movement. The drill bits 8 are firmly mounted on the body 1 and have the ability to rotate freely. During the operation, the drill bits 8 gradually move downward until they contact the surface of the spiral tube. Once the contact is successful, the drill bits 8 immediately start to perform the drilling operation and form the required holes on the spiral tube. When the pipe seam is spiral, the spacing between adjacent drill bits 8 is the same as the pitch of the spiral pipe seam.

[0036] The support unit includes a clearance groove and a support shaft. The drill bit 8 can extend to the inside of the clearance groove. After completing the drilling operation on the spiral tube, the drill bit 8 will continue to move downward until it penetrates the spiral tube and enters the pre-designed clearance groove. There are two support shafts, which are respectively arranged on both sides of the clearance groove. During the drilling process, the support shafts are against the inner wall of the spiral tube. The support shafts are symmetrically arranged on both sides. These support shafts are precisely located on both sides of the clearance groove to effectively support the spiral tube. When the drilling operation is in progress, the two symmetrical support shafts can act on the spiral tube together, significantly reducing the risk of deformation of the spiral tube due to the pressure applied by the drill bit 8.

[0037] Embodiment 2

[0038] like Figure 1-Figure 5 As shown, based on the first embodiment, this embodiment provides a structure of a support unit, which is as follows:

[0039] The support unit also includes a support plate 2 and a driving body 3. A clearance groove is provided inside the support plate 2. Two support shafts are rotatably mounted on both sides of the upper end of the support plate 2. In this embodiment, the support plate 2 is designed as a stable component of the support shaft, and the extension direction of both is the same as the moving trajectory of the spiral tube. The clearance groove is provided on the upper surface of the support plate 2. When the drill bit 8 performs the drilling task, it moves from top to bottom. Once the drilling operation is successfully completed, the drill bit 8 will maintain its movement direction and continue to move downward, and accurately embed into the clearance groove to ensure smooth and safe operation.

[0040] There is a gap between the driving body 3 and the support plate 2, and the driving body 3 and the support plate 2 can move relative to each other. The extension direction of the driving body 3 is also the same as the movement direction of the spiral tube. The driving body 3 is arranged at the bottom of the support plate 2 and is parallel to the support plate 2.

[0041] Among them, when the support unit is inserted into the spiral tube, the support plate 2 and the driving body 3 are respectively against the upper and lower sides of the spiral tube, the support plate 2 and the driving body 3 support the spiral tube, and when they are against the inner wall of the spiral tube, when the driving body 3 rotates, it will drive the spiral tube to rotate. A push plate 6 is provided in the gap between the support plate 2 and the driving body 3. The push plate 6 can push the spiral tube to move. When the spiral tube needs to move, the push plate 6 will push the spiral tube to move on the support unit.

[0042] The push plate 6 is slidably mounted on the bottom of the support plate 2. The moving direction of the push plate 6 is along the moving direction of the spiral tube, and a positioning surface for positioning the end of the spiral tube is provided on the push plate 6. During the installation of the spiral tube, the end of the spiral tube will accurately abut against the surface of the push plate 6. This contact realizes the effective positioning function of the end of the spiral tube. In order to realize the flexible movement of the push plate 6, an electric push rod or a cylinder can be used as a power source. The output rod of these driving devices is directly connected to the push plate 6. Through the extension and shortening of the output rod, the push plate 6 can be driven to move along a preset trajectory, thereby meeting the positioning requirements during the installation of the spiral tube.

[0043] Embodiment 3

[0044] like Figure 1-Figure 5 As shown, based on the first and second embodiments, this embodiment provides a method for installing the support plate and the driving body, which is as follows:

[0045] The body 1 includes a base frame 101, a top frame 103 and a connecting frame 102 connected between the base frame 101 and the top frame 103, the support plate 2 and the driving body 3 are both installed on the connecting frame 102, one end of the support plate 2 is fixed on the connecting frame 102, one end of the driving body 3 is rotatably installed on the connecting frame 102, and a motor that can drive the driving body 3 to rotate is fixed inside the connecting frame 102.

[0046] A support plate 7 is rotatably mounted on the top frame 103, and the support plate 7 is clamped with one end of the support plate 2 away from the connecting frame 102. A side plate 4 is fixed to the end of the support plate 2 away from the support plate 7. The side plate 4 is connected to a driving body 3 located at the bottom, and the driving body 3 is rotatably connected to the side plate 4. The support plate 7 is clamped with the side plate 4, and the clamping method is to connect the clamping block 5 with the clamping groove. The clamping block 5 is fixed on the side plate 4, and a clamping groove is provided on the support plate 7, and the clamping groove is clamped on the clamping block 5.

[0047] The pushing channel is opened on the surface of the base frame 101. The surface of the base frame 101 is an inclined surface with the bottom approaching inward. A conveyor belt 11 for conveying the spiral tube is installed on the inclined surface, which can effectively ensure that the spiral tube is in contact with the conveyor belt 11 and drive the spiral tube to move through the conveyor belt 11.

[0048] The support plate 2 is slidably mounted on the connecting frame 102, and a cylinder is fixed inside the connecting frame 102 for driving the support plate 2 to slide. The cylinder drives the support plate 2 to move on the connecting frame 102 to change the distance between the support plate 2 and the driving body 3, so that the support plate 2 and the driving body 3 support the spiral tube.

[0049] The support plate 2 and the base frame 101 are both provided with storage troughs 9, which are used to store waste generated by punching. The waste generated by punching on the support plate 2 falls into the two storage troughs 9. Since the bottom of the pushing channel is in an inverted cone shape, the waste will flow downward into the storage troughs 9.

[0050] A discharging screw 10 is rotatably installed in the material storage trough 9 inside the support plate 2 and the bottom frame 101 , and the discharging screw 10 can collectively discharge the waste materials dropped into the material storage trough 9 to the outside of the machine body 1 .

[0051] Working principle:

[0052] During the installation of the spiral tube, the support plate 7 is first rotated to create a space for the spiral tube to be inserted smoothly. Once the spiral tube is in place, the support plate 7 is immediately reset to firmly support the support plate 2 and the driving body 3, and the spiral tube is precisely positioned on a specific surface of the push plate 6. After the positioning is completed, the support plate 2 and the driving body 3 work together to expand outward to firmly clamp the spiral tube.

[0053] Then, the punching mechanism slowly descends under control, and uses the multiple drill bits 8 on it to accurately punch a row of holes on the surface of the spiral tube. After the punching operation is completed, the driver 3 is activated to rotate, driving the spiral tube to rotate to a preset angle. Then, the push plate 6 pushes the spiral tube to move a certain distance in a certain direction to prepare a new position for the next round of punching operation.

[0054] This process of "rotating-moving-punching" will be repeated until a series of holes distributed in a spiral are formed on the spiral tube. After the whole process is completed, the support plate 7 can be opened to easily replace the processed spiral tube and prepare for the processing of the next spiral tube.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
