Description

Technical Field

[0001] This invention relates to the field of corrugated pipe processing technology, specifically a multi-segment rapid prototyping method for corrugated pipes. Background Technology

[0002] Double-wall corrugated pipe is a new type of lightweight pipe with a ring-shaped outer wall and a smooth inner wall, belonging to the category of flexible pipes. Its main characteristic is the annular corrugated structure of the outer wall, which enhances the pipe's ring stiffness. It is a material with chemical stability, aging resistance, and resistance to environmental stress cracking. Therefore, double-wall corrugated pipe not only possesses excellent physical properties but also good chemical stability.

[0003] During the processing of corrugated pipes, customization can be made according to customer needs to produce shorter lengths of corrugated pipes for short-distance connections or applications with fewer bends, thus meeting the requirements of special occasions.

[0004] A search revealed a Chinese patent (publication number: CN109500855B) that discloses a corrugated pipe cutting device with adjustable spacing. The patent includes a worktable, a cutting protective cover installed on the upper outer surface of the worktable, support frames fixedly installed at the corners of the lower outer surface of the worktable, and pads provided on the lower outer surface of the support frames. A hydraulic cylinder is installed in the middle of the upper outer surface of the cutting protective cover, and a telescopic groove is provided at the bottom of the hydraulic cylinder. A hydraulic rod is movably installed inside the telescopic groove, and a cutting tool is installed in the middle of the lower outer surface of the hydraulic rod. Two sets of bases are fixedly installed on the upper outer surface of the worktable and inside the cutting protective cover, and slide rails are provided on the upper outer surface of the bases.

[0005] After the corrugated pipe is processed, it needs to be stored in a unified manner to facilitate subsequent transportation and reprocessing. Therefore, it is necessary to efficiently and accurately recycle the processed corrugated pipe. Thus, this invention proposes a multi-segment rapid prototyping method for corrugated pipes. Summary of the Invention

[0006] The purpose of this invention is to provide a multi-segment rapid prototyping method for corrugated pipes.

[0007] The technical problem solved by this invention is: how to quickly process corrugated pipes to obtain products of multiple required lengths;

[0008] How to efficiently and accurately recycle processed products.

[0009] This invention can be achieved through the following technical solution: a multi-segment rapid prototyping method for corrugated pipes, which includes the following steps:

[0010] Step 1: Adjust the spacing of each segment component in the processing device based on the length of the product to be processed. At the same time, the positioning frame is activated, and the positioning components adjust each dividing mechanism to the underside of each segment component.

[0011] Step 2: The corrugated pipe to be processed is transported to the processing device, and then each segment component is started to simultaneously process the corrugated pipe into segments to obtain products of the corresponding length.

[0012] Step 3: Each separating mechanism rises between the products, then pushes each product in the same direction, and separates the product from the processing device at the same location in the processing device;

[0013] After the product is separated from the processing device, a set of separation mechanisms on the corresponding side resets.

[0014] Step 4: The positioning frame moves each dividing mechanism back to the underside of the corresponding segment component based on the positioning component, and then repeats steps 2 to 3 to process the bellows again.

[0015] A further technical improvement of the present invention is that the processing device includes a base frame, a sliding frame is mounted on the upper side of the base frame, and a plurality of segmented components are mounted on the upper side of the sliding frame. In use, the plurality of segmented components are adjusted based on the length of the product and fixed on the upper side of the sliding frame.

[0016] One end of the base frame is provided with a feed inlet, and the other end of the base frame is provided with a product outlet, and a pushing component is installed in the product outlet;

[0017] During processing, the corrugated pipe enters through the feed inlet, with one end abutting against the product outlet side. After being segmented by the segmentation assembly, each product moves along the direction from the feed inlet to the product outlet, and pushes the assembly to be discharged from the product outlet in sequence.

[0018] A positioning frame is provided on the lower side of the base frame. A positioning component is installed at the output end of the positioning frame. The positioning component is provided with multiple moving ends, and each moving end is equipped with a separation mechanism.

[0019] After the positioning frame is started, it moves each moving end of the positioning component and drives each separating mechanism to move to the underside of the corresponding segment component.

[0020] A further technical improvement of the present invention is that: the segmented assembly includes a sliding seat connected to the sliding frame, a lifting assembly is mounted on the side of the sliding seat, and a segmenting mechanism is mounted on the output end of the lifting assembly;

[0021] The sliding frame has a groove inside for the movement of the lifting assembly and the segmentation mechanism.

[0022] A further technical improvement of the present invention is that: the pushing component includes a guide frame, which is installed inside the product outlet for supporting the product from the bottom;

[0023] A stroke cylinder is installed on the lower side of the guide frame. A contact roller is installed at the output end of the stroke cylinder, and the output end of the stroke cylinder is inclined towards the product outlet. A moving channel for the contact roller to move is opened inside the guide frame.

[0024] After the stroke cylinder is activated, the contact roller moves along the guide frame's moving channel, contacts the product, and pushes it out of the product outlet.

[0025] A further technical improvement of the present invention is that: the positioning frame includes an assembly box, and a plurality of sliding rods are installed inside the assembly box, each sliding rod being parallel to the direction of movement of the corrugated pipe on the base frame;

[0026] Each sliding rod has a locking seat slidably connected to its outer side. After each locking seat is slid to the required position, it is fixed to the outer side of the corresponding sliding rod by a locking component.

[0027] Each of the locking seats is equipped with a first positioning plate on its upper side. The first positioning plates are distributed in a stepped manner along the moving direction perpendicular to the bellows, and the first positioning plates are not located on the same axial direction.

[0028] Inside the assembly box, a horizontal drive mechanism is installed on one side of each sliding rod, and a drive seat is installed at the output end of the horizontal drive mechanism.

[0029] A further technical improvement of the present invention is that the positioning component includes a storage tube and multiple sliding tubes;

[0030] The storage tube is connected to the end of the assembly box that faces away from the base frame feed inlet;

[0031] The sliding tubes are connected in sequence to form the structure of an expansion joint;

[0032] Each sliding tube has an extension plate installed on its lower side, and each extension plate has a second positioning plate installed on its lower side.

[0033] The length of each extension plate increases as the corresponding sliding tubes decrease toward the base frame inlet, meaning the extension plate on the lower side of the set of sliding tubes closest to the base frame inlet is the longest.

[0034] A second positioning plate is installed on the underside of each extension plate;

[0035] The second positioning plate on the lower side of the sliding tube closest to the base frame feed inlet is on the same axial extension line as the drive seat, and the distribution positions of the second positioning plates on the lower side of the other sliding tubes match the corresponding first positioning plates;

[0036] After the horizontal drive mechanism is started, it drives the drive seat to contact the second positioning plate on the lower side of the sliding tube closest to the base frame feed port, thereby driving the sliding tube to move. The other sliding tubes slide synchronously through the friction between them and the adjacent sliding tubes.

[0037] After each sliding tube slides, the second positioning plate on its lower side will come into contact with the matching first positioning plate. After contact, the sliding tube group will stop moving.

[0038] A further technical improvement of the present invention is that: each sliding tube is equipped with an elastic element between itself and the adjacent receiving tube or sliding tube, which is used to assist each sliding tube in unfolding, and after the drive seat disconnects from the corresponding second positioning plate, the elastic element does not pull the corresponding sliding tube to avoid pushing the product.

[0039] A further technical improvement of the present invention is that the separating mechanism includes a lifting cylinder, the output end of which faces upward and is mounted on a plate.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] This invention allows for the simultaneous segmentation of corrugated pipes during processing. After segmentation, a separating mechanism separates each segment, and subsequently, each segment is discharged sequentially from the product outlet of the processing device, facilitating the collection of the segmented products by workers.

[0042] Furthermore, the segmented components and separation mechanism in the processing device of the present invention can be adjusted based on the required product length, thereby increasing the applicability and scope of use of the device. At the same time, by setting the separation mechanism, the contact surface between adjacent products can be increased when each segment of the product moves, thereby fixing the movement path of the product and preventing each segment of the product from separating from the base frame.

Detailed Implementation

[0051] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0052] Please see Figure 1-6 As shown, a multi-segment rapid prototyping method for corrugated pipes includes the following steps:

[0053] Step 1: Adjust the processing device, which includes a base frame 1, a sliding frame 2 installed on the upper side of the base frame 1, and multiple segmented components 3 installed on the upper side of the sliding frame 2. In use, the multiple segmented components 3 are adjusted based on the length of the product and fixed on the upper side of the sliding frame 2.

[0054] The segmented assembly 3 includes a sliding seat 31 connected to the sliding frame 2, a lifting assembly 32 mounted on the side of the sliding seat 31, and a segmented mechanism 33 mounted on the output end of the lifting assembly 32.

[0055] The sliding frame 2 has a groove inside for the movement of the lifting assembly 32 and the segmentation mechanism 33;

[0056] One end of the base frame 1 is provided with a feed inlet, and the other end of the base frame 1 is provided with a product outlet, and a push assembly 7 is installed in the product outlet;

[0057] During processing, the corrugated pipe enters from the feed inlet, with one end abutting against the side of the product outlet. After the segmentation component 3 segments it, each product moves along the direction from the feed inlet to the product outlet, and pushes the component 7 to be discharged from the product outlet in sequence.

[0058] A positioning frame 4 is provided on the lower side of the base frame 1. A positioning component 6 is installed at the output end of the positioning frame 4. The positioning component 6 is provided with multiple moving ends, and each moving end is equipped with a separation mechanism 5.

[0059] The separation mechanism 5 includes a lifting cylinder 51, the output end of which faces upward and is fitted with a plate 52.

[0060] After the positioning frame 4 is started, it moves each moving end of the positioning component 6 and drives each separating mechanism 5 to move to the lower side of the corresponding segment component 3.

[0061] Please see Figure 2 As shown, the push assembly 7 includes a guide frame 71, which is installed inside the product outlet to support the product from the bottom;

[0062] A stroke cylinder 72 is installed on the lower side of the guide frame 71. A contact roller 73 is installed at the output end of the stroke cylinder 72. The output end of the stroke cylinder 72 is inclined towards the product outlet. A moving channel for the contact roller 73 to move is opened inside the guide frame 71.

[0063] After the stroke cylinder 72 is activated, the contact roller 73 moves along the moving channel of the guide frame 71, and after contacting the product, it pushes the product out from the product outlet;

[0064] Please see Figure 3-4 As shown, the positioning frame 4 includes an assembly box 41, and multiple sliding rods 42 are installed inside the assembly box 41. Each sliding rod 42 is parallel to the direction of movement of the corrugated pipe on the base frame 1.

[0065] Each sliding rod 42 is slidably connected to a locking seat 43 on its outer side. After each locking seat 43 is slid to the required position, it is fixed to the outer side of the corresponding sliding rod 42 by a locking member.

[0066] Each locking seat 43 is equipped with a first positioning plate 44 on its upper side. Each first positioning plate 44 is distributed in a stepped manner along the moving direction perpendicular to the bellows, and each first positioning plate 44 is not located on the same axial direction.

[0067] Inside the assembly box 41, a horizontal drive mechanism 45 is installed on one side of each sliding rod 42, and a drive seat 46 is installed at the output end of the horizontal drive mechanism 45.

[0068] Please see Figure 5-6 As shown, the positioning component 6 includes a storage tube 61 and multiple sliding tubes 62;

[0069] The storage tube 61 is connected to one end of the assembly box 41 that faces away from the feed port of the base frame 1;

[0070] Each sliding tube 62 is slidably connected in sequence to form an expansion joint structure;

[0071] Each sliding tube 62 has an extension plate 63 installed on its lower side, and each extension plate 63 has a second positioning plate 64 installed on its lower side.

[0072] The length of each extension plate 63 increases as the corresponding sliding tube 62 decreases toward the feed inlet of the base frame 1, that is, the extension plate 63 on the lower side of the set of sliding tubes 62 closest to the feed inlet of the base frame 1 is the longest.

[0073] A second positioning plate 64 is installed on the lower side of each extension plate 63;

[0074] The second positioning plate 64, which is closest to the bottom of the sliding tube 62 at the feed inlet of the base frame 1, is on the same axial extension line as the drive seat 46. The second positioning plates 64 on the bottom of the remaining sliding tubes 62 are matched with the positions of the first positioning plates 44 in a stepped distribution in order of moving away from the feed inlet.

[0075] An elastic element 65 is installed between the group of sliding tubes 62 closest to the storage tube 61 and the storage tube 61. Elastic elements 65 are installed between the remaining sliding tubes 62 and the adjacent sliding tubes 62 to assist each sliding tube 62 in unfolding. After the drive seat 46 disconnects from the corresponding second positioning plate 64, each elastic element 65 does not pull the sliding tube 62 to avoid pushing the product.

[0076] In this embodiment, the extension plate 63 on the lower side of the sliding tube 62 that is closer to the receiving tube 61 is shorter, and the locking seat 43 and the first positioning plate 44 corresponding to the lower extension plate 63 are closer to the product outlet.

[0077] When in use, first adjust the spacing of each segment component 3 in the processing device according to the length of the product to be processed. At the same time, the horizontal drive mechanism 45 in the positioning frame 4 is started. After the horizontal drive mechanism 45 is started, it drives the drive seat 46 to contact the second positioning plate 64 on the lower side of the sliding tube 62 closest to the feed port of the base frame 1, thereby driving the sliding tube 62 to move. The other sliding tubes 62 slide synchronously through the friction between them and the adjacent sliding tubes 62.

[0078] After each sliding tube 62 slides, the second positioning plate 64 on its lower side will contact the matching first positioning plate 44. After contact, the sliding tube 62 will stop moving. When each sliding tube 62 moves, each separating mechanism 5 will be adjusted to the lower side of each segment component 3. Then the horizontal drive mechanism 45 will reset the drive seat 46 and wait for restart.

[0079] Step 2: The corrugated pipe to be processed is transported to the processing device, and then each segment component 3 is started to simultaneously process the corrugated pipe into segments to obtain products of the corresponding length.

[0080] Step 3: The lifting cylinder 51 in each of the separation mechanisms 5 is activated, raising the plate 52 between the corresponding two groups of products, and pushing the stroke cylinder 72 in the component 7 to activate, pushing the product located on the upper side of the guide frame 71 away from the processing device along the product outlet;

[0081] The remaining products are then pushed toward the product outlet. As each product moves, the contact area with adjacent products is increased by the plate 52, which facilitates the movement of each product along the same axis.

[0082] After the pusher component 7 moves the corresponding product to the product outlet, it pushes the product outlet away sequentially.

[0083] After the product is separated from the processing device, a set of separation mechanisms 5 on the corresponding side resets, and the plate 52 is lowered to the lower side of the product's movement path.

[0084] Step 4: The positioning frame 4 moves each dividing mechanism 5 back to the underside of each corresponding segment component 3 based on the positioning component 6, and then repeats steps 2 to 3 to process the bellows again.

[0085] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
