Description

Technical Field

[0001] This invention relates to the field of pipe fitting processing equipment, and in particular to an automatic double-end processing equipment for pipe fittings. Background Technology

[0002] Currently, in the pipe fitting processing process, when processing both ends of the pipe fitting, most existing processing equipment and production lines are integrated for processing steps at only one end of the pipe fitting, which is not very versatile. When both ends of the pipe fitting need to be processed, multiple material transfers are required during the processing, involving a lot of manual intervention, which leads to more uncertainties and affects the final consistency of the product. At the same time, the current products are usually inspected manually for the degree of completion during processing, which is not reliable and wastes manpower. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic double-end processing device for pipe fittings that solves the above-mentioned problems.

[0004] To solve the above-mentioned technical problems, the present invention provides an automatic double-end processing equipment for pipe fittings, including a worktable, an oil removal and detection device disposed on the worktable, and an automatic pipe fitting turning processing device disposed on the worktable. The oil removal and detection device is connected to the automatic pipe fitting turning processing device in operation. The oil removal and detection device includes a chamfering component, an oil removal component, and a detection component arranged in sequence. The oil removal component includes a movable first clamping mold, a first air blowing plate disposed on one side of the first clamping mold, and a first oil suction ventilation pipe connected to one side of the first air blowing plate. The first air blowing plate has a first air blowing inlet on the side near the first clamping mold. When the pipe fitting is clamped at the first clamping mold, the pipe fitting enters the first air blowing plate through the first air blowing inlet.

[0005] Furthermore, the detection component includes a movable second clamping mold and a rotatable detector located on one side of the second clamping mold. The detector is located inside the detection box. When the pipe is clamped at the second clamping mold, the detector rotates along the outer periphery of the pipe for detection.

[0006] Furthermore, the detection component also includes a second air blowing plate disposed on one side of the second clamping mold and a second oil suction ventilation pipe connected to one side of the second air blowing plate. The second air blowing plate has a second air blowing inlet on the side near the second clamping mold. When the pipe is clamped at the second clamping mold, the pipe enters the second air blowing plate through the second air blowing inlet.

[0007] Furthermore, the chamfering component includes a movable third clamping mold and a rotatable chamfering blade located on one side of the third clamping mold. The chamfering blade has a protective cover on its outer periphery, and the protective cover has a chamfering inlet on the side closer to the third clamping mold, while the protective cover has a negative pressure chip suction port on the side away from the third clamping mold.

[0008] Furthermore, the chamfering component, the degreasing component, and the inspection component all include a material support bracket, with the end of the pipe furthest from the processing position placed on the material support bracket.

[0009] Furthermore, the automatic pipe turning processing equipment includes a turning component and a pipe end processing component. The turning component includes a movably set turning seat and a rotatable turning clamping mold set on the turning seat. When the pipe is clamped on the turning clamping mold, the turning clamping mold rotates relative to the turning seat to change the position of the two ends of the pipe.

[0010] Furthermore, a turning positioning plate is provided on one side of the turning clamp. When the two ends of the pipe are switched, the turning seat drives the pipe to move so that one end of the pipe abuts against the turning positioning plate.

[0011] Furthermore, the pipe end processing component includes a pipe end processing clamping mold, a movable punch seat located on one side of the pipe end processing clamping mold, and a plurality of punches located on the punch seat. When the pipe is clamped at the pipe end processing clamping mold, the punch seat moves so that the punches correspond to the processing end of the pipe.

[0012] Furthermore, the punch holder is mounted on the drive seat in a height-adjustable manner, and several punches are distributed at intervals along the height direction of the punch holder.

[0013] Furthermore, a track is laid at the bottom of the drive seat, allowing the drive seat to move relative to the track so that the drive seat can move the punch closer to or away from the pipe fitting.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. When the chamfering component is used to chamfer the end of the pipe fitting, it works in conjunction with the protective cover and the negative pressure chip suction port to collect and remove the waste chips generated during the chamfering process, thereby improving the waste chip cleaning effect;

[0016] 2. The air blowing plate and oil suction ventilation pipe in the degreasing and detection components work together to remove residual oil stains on the pipes, increasing the accuracy of detection and the cleanliness of the final product;

[0017] 3. Rotation detection detectors can effectively detect the completion degree of products, improving the reliability of product production;

[0018] 4. The turning component allows the equipment to process both ends of the pipe fitting without having to transfer the material after processing one end, thus greatly reducing processing time and reducing the equipment's footprint.

[0019] 5. The lifting and lowering movement of the punch seat is coordinated with the movement of the drive seat, which allows for the rapid stamping and processing of various required pipe end forms without moving the pipe during pipe end processing. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0029] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0030] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0031] like Figure 1-7 The present invention provides an automatic double-end processing equipment for pipe fittings, including a workbench 1, an oil removal and testing device 2 disposed on the workbench, and an automatic pipe fitting turning processing device 3 disposed on the workbench 1. The oil removal and testing device 2 and the automatic pipe fitting turning processing device 3 are connected in operation. The oil removal and testing device 2 includes a chamfering component, an oil removal component, and a testing component arranged in sequence. The oil removal component includes a movable first clamping mold 21, a first air blowing plate 22 disposed on one side of the first clamping mold 21, and a first oil suction ventilation pipe 23 connected to one side of the first air blowing plate 22. The first air blowing plate 22 has a first air blowing inlet 24 on the side near the first clamping mold 21. When the pipe fitting 4 is clamped at the first clamping mold 21, the pipe fitting 4 enters the first air blowing plate 22 through the first air blowing inlet 24.

[0032] Specifically, after the pipe fitting is fed into the equipment, one end of the pipe fitting is processed first. After the processing of this end is completed, the pipe fitting moves sequentially to the chamfering component, the degreasing component, and the inspection component. When the pipe fitting moves to the degreasing component, it is clamped and fixed by the first clamping mold. While keeping the pipe fitting fixed, the first clamping mold moves to drive the pipe fitting from the first air inlet into the first air blowing plate. At this time, the first air blowing plate is connected to an external jetting device to blow air onto the pipe fitting inside the first air blowing plate. At the same time, the first oil suction ventilation pipe is connected to an external suction device, so that the first oil suction ventilation pipe simultaneously suctions the pipe fitting. This disperses the residual oil on the pipe fitting under the action of air blowing, and then it is sucked away by the first oil suction ventilation pipe to complete the degreasing process of the pipe fitting.

[0033] It is worth mentioning that this solution can use either automatic mechanical feeding or manual feeding when loading pipe fittings. When using automatic mechanical feeding, the solution can utilize, for example, the patent titled "Pipe Fitting Feeder and Its Usage Method" (application number "CN202211622863.3") for automatic pipe loading. The processing of the pipe fittings before they move to the chamfering component can be performed using, for example, the patent titled "An Adjustable Grooving Chuck" (application number "CN202221564269.9"). Furthermore, when processing the pipe ends, this solution also requires a flange riveting step on one end of the pipe fitting. In this case, the patent titled "A Simple Automatic Flange Riveting Structure" (application number "202221721672.8") can be used to perform the flange riveting operation on the pipe end of the pipe fitting.

[0034] In one embodiment of this solution, adjacent workstations of the chamfering component, degreasing component, inspection component, and subsequent turning component and pipe end processing component are all equipped with robotic arms for transfer operations. For example, after the pipe is chamfered by the chamfering component, the pipe is transferred to the degreasing component by the robotic arm, so that the transfer of the pipe is more convenient and no manual operation is required.

[0035] Preferably, the detection component includes a movable second clamping mold 25 and a rotatable detector disposed on one side of the second clamping mold 25. The detector is disposed in the detection box 26. When the pipe 4 is clamped at the second clamping mold 25, the detector rotates and detects along the outer periphery of the pipe 4.

[0036] Specifically, after the pipe fitting is degreased, it is moved to the detection unit. At this time, the pipe fitting is clamped and fixed by the second clamping mold. Then the second clamping mold moves and drives the pipe fitting to the detector. At the same time, the detector rotates synchronously, so that the pipe fitting is moved while being detected by the detector in the circumferential rotation of the pipe fitting, thereby improving the detection effect.

[0037] In one embodiment of this solution, the detector uses a Keyence™-5000 two-dimensional high-speed projection dimension measuring instrument to perform CCD inspection on the forming section of the pipe fitting. Since the Keyence™-5000 can intelligently detect dimensions online and quickly and accurately acquire detection data, it ensures the detection effect of the detection station on the forming section of the pipe fitting in this solution.

[0038] It is worth mentioning that the detector is connected to the servo motor module, which drives the detector to rotate.

[0039] Preferably, the detection component further includes a second air-blowing plate 27 disposed on one side of the second clamping mold 25 and a second oil-absorbing ventilation pipe 28 connected to one side of the second air-blowing plate 27. The second air-blowing plate 27 has a second air-blowing inlet 29 on the side near the second clamping mold 25. When the pipe 4 is clamped at the second clamping mold 25, the pipe 4 enters the second air-blowing plate 27 through the second air-blowing inlet 29.

[0040] Specifically, after the pipe is moved to the detection component and clamped and fixed by the second clamping mold, the second clamping mold drives the pipe to move towards the second air blowing plate. The second air blowing plate and the second oil suction ventilation pipe are used in the same way as in the oil removal component, thereby enabling the pipe to undergo secondary oil removal to ensure the accuracy of the detector in detecting the pipe.

[0041] Preferably, the chamfering component includes a movably disposed third clamping mold 210 and a rotatable chamfering blade 211 disposed on one side of the third clamping mold 210. The chamfering blade 211 has a protective cover 212 on its outer periphery, and the protective cover 212 has a chamfering inlet 213 on the side close to the third clamping mold 210, and a negative pressure chip suction port 214 connected to the side of the protective cover 212 away from the third clamping mold 210.

[0042] Specifically, before the pipe fittings are degreased, they also need to be chamfered. At this time, the pipe fittings are fixed by the third clamping mold and moved to the position of the chamfering knife. After the pipe fittings are moved to the designated position, the chamfering knife rotates and chamfers the part of the pipe fittings to be processed. At this time, the protective cover can effectively block the waste generated by chamfering, and the waste is sucked up by the negative pressure suction port so that the waste can be easily cleaned up.

[0043] It is worth mentioning that the first, second, and third clamping molds have similar structures, each with two grippers. The grippers are controlled by a cylinder to hold or separate. The bottom of the first, second, and third clamping molds is laid with a track so that they can move relative to the track. Furthermore, a servo motor is connected to one side of the first, second, and third clamping molds, which controls their movement along the track.

[0044] In one embodiment of this solution, the negative pressure suction port is connected to an external negative pressure suction device to suction the waste.

[0045] Preferably, the chamfering component, the degreasing component, and the inspection component all include a material support bracket 215, with the end of the pipe 4 furthest from the processing position placed on the material support bracket 215.

[0046] Specifically, for some longer pipe fittings, in order to prevent the end of the pipe fitting from drooping downwards due to excessive length, this solution uses a material support bracket to place the end of the pipe fitting that is far from the processing position on the material support bracket, ensuring that the pipe fitting will not droop downwards during processing.

[0047] In one embodiment of this solution, the material support bracket is arranged in a "Y" shape.

[0048] Preferably, the automatic pipe turning processing equipment 3 includes a turning component and a pipe end processing component. The turning component includes a movably set turning seat 31 and a rotatable turning clamping mold 32 set on the turning seat 31. When the pipe 4 is clamped on the turning clamping mold 32, the turning clamping mold 32 rotates relative to the turning seat 31 so that the two ends of the pipe 4 are interchanged.

[0049] Specifically, after one end of the pipe fitting is processed, the pipe fitting is moved to the turning component. At this time, the pipe fitting is clamped by the turning clamping mold. Then, as the turning clamping mold rotates relative to the turning base, the pipe fitting rotates with the turning clamping mold, thereby changing the position of the two ends of the pipe fitting so that the other end of the pipe fitting can be processed later.

[0050] It is worth mentioning that the bottom of the turning seat is laid with a track, and the turning seat is connected to a servo motor. The servo motor controls the turning seat to move along the track. At the same time, a rotary cylinder is connected between the turning clamp and the turning seat, and the rotary cylinder controls the rotation of the turning seat.

[0051] In addition, the clamping method of the turning clamping mold on the pipe fitting is the same as that of the first clamping mold on the pipe fitting.

[0052] Preferably, a turning positioning plate 33 is provided on one side of the turning clamping mold 32. When the two ends of the pipe 4 are switched, the turning seat 31 drives the pipe 4 to move so that one end of the pipe 4 abuts against the turning positioning plate 33.

[0053] Specifically, after the turning clamping mold changes the positions of the two ends of the pipe fitting, the turning seat moves along the track so that one end of the pipe fitting abuts against the turning positioning plate, thereby controlling the position of the pipe end and ensuring that the pipe end position will not be too close or too far during subsequent processing.

[0054] In one embodiment of this solution, a distance sensor, a pressure sensor, etc., can be installed on the turning positioning plate to detect whether the pipe is in contact with the turning positioning plate.

[0055] Preferably, the pipe end processing component includes a pipe end processing clamping mold 34, a movable punch seat 35 disposed on one side of the pipe end processing clamping mold 34, and a plurality of punches 36 disposed on the punch seat 35. When the pipe 4 is clamped at the pipe end processing clamping mold 34, the punch seat 35 moves so that the punches 36 correspond to the processing end of the pipe 4.

[0056] Specifically, after the pipe fitting is turned around and moved to the position of the pipe end processing component, the pipe fitting is clamped and fixed by the pipe end processing mold. The punch seat moves and drives the designated punch to the corresponding position at the end of the pipe fitting, so that each punch can perform targeted pressurization processing on the end of the pipe fitting.

[0057] It is worth mentioning that the clamping method of the pipe end processing clamping mold for the pipe fitting is the same as that of the first clamping mold for the pipe fitting.

[0058] Preferably, the punch holder 35 is vertically and flexibly mounted on the drive seat 37, and a plurality of punches 36 are spaced apart along the height direction of the punch holder 35.

[0059] Specifically, when adjusting the position of each punch corresponding to the tube end, the punch holder moves up and down relative to the drive seat to adjust the position of each punch that is spaced apart along the height direction of the punch holder, so as to ensure that the punch can be accurately moved to the corresponding processing position.

[0060] In one embodiment of this solution, a cylinder is provided on the drive seat, and the cylinder controls the lifting and lowering movement of the punch seat relative to the drive seat, thereby controlling the die changing of the punch.

[0061] Preferably, a track 38 is laid at the bottom of the drive seat 37, and the drive seat 37 can move relative to the track 38 so that the drive seat 37 drives the punch 36 to move closer to or away from the pipe fitting 4.

[0062] Specifically, after the punch moves to the corresponding processing position, the drive seat moves along the track, thereby driving the punch to approach the pipe and perform stamping processing on the pipe end.

[0063] In one embodiment of this solution, a hydraulic cylinder is provided on one side of the drive seat, and the hydraulic cylinder controls the stamping movement of the drive seat and the punch seat.

[0064] It is worth mentioning that after the pipe fittings are finally processed, the 6-axis robot will place qualified products into the material frame for stacking and defective products into the waste box. When the material frame is full, an alarm will be automatically triggered (which can be detected by a height sensor). The material frame will then be manually placed into the cleaning tank for cleaning.

[0065] In one embodiment of this solution, safety light curtains and safety railings are arranged around the material frame and around the 6-axis robot.

[0066] In particular, the automatic double-end processing equipment for pipe fittings in this solution is also equipped with an electronic production status dashboard and an industrial control computer to facilitate on-site management and product traceability for operators.

[0067] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
