Description

Technical Field

[0001] This invention relates to the field of pipe processing technology, and specifically to a process and equipment for processing imitation oil injection pipes. Background Technology

[0002] Pipes are materials used to make pipe fittings. Different scenarios and needs require different processing methods for pipes. Since simple round or square shapes are insufficient for various scenarios, irregularly shaped pipes exist. The processing method for irregularly shaped pipes is oil injection molding, which involves injecting oil into the pipe and pressing it with upper and lower molds to form the shape. However, oil injection molding requires large equipment, and the molds used are large and complex, resulting in a long mold-making cycle. Therefore, the mold-making and sample delivery time can be as long as six months, which is detrimental to market share. Furthermore, small businesses may not have the large equipment, so they may not be able to use this method to process irregularly shaped pipes. Additionally, oil leakage during injection can have an environmental impact. Summary of the Invention

[0003] The purpose of this invention is to provide a processing technology and equipment for imitation oil injection pipes. By using pipe shrinking and stamping in conjunction with a mold core, this invention replaces oil injection molding.

[0055] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0056] like Figure 1 As shown, a process for processing imitation oil injection pipe includes the following steps:

[0057] S1: Place the cut pipe 1 onto the clamping device 2, with one end of the pipe 1 inside the shrinking device 3, and start the shrinking device 3 to shrink the pipe.

[0058] S2: Place the tube 1 after shrinking into the pre-forming mold 5 on the stamping device 4, and put the mold core 6 inside the tube 1. Then start the stamping device 4 to perform pre-forming.

[0059] S3: Remove the mold core 6, place the pre-formed tube into the R-arc forming mold 7 on the stamping device 4, and start the stamping device 4 to perform R-arc processing.

[0060] S4: Polishing.

[0061] Therefore, in actual use, the method of tube shrinking and stamping combined with mold core 6 is used to replace oil injection molding. Compared with oil injection molding, the present invention does not require oil injection equipment, so it will not have an impact on the environment. Moreover, since there is no oil injection equipment, the overall equipment size can be reduced, thereby reducing the size of the mold and shortening the time.

[0062] Meanwhile, the cut pipe 1 is a seamless pipe with a Wechsler hardness of 0-7HW.

[0063] Secondly, the mold core 6 is a separate unit. The specific structure is as follows: First, the mold core 6 includes mold core one 61 and mold core two 62. One end of mold core one 61 is located inside mold core two 62, and the other end of mold core one 61 extends out of the tube and the pre-forming mold 5 in sequence and is exposed. The width or height of the end of mold core one 61 that extends out of the tube is greater than the diameter of the tube.

[0064] Furthermore, the end of mold core 2 62 that is away from mold core 1 61 extends out of the pipe and is exposed, and the width or height of the end of mold core 2 62 that extends out of the pipe is greater than the diameter of the pipe, and the length of mold core 2 62 inside the pipe is equal to the length of the pipe.

[0065] Therefore, in actual use, the installation and removal of mold core 6 are facilitated by the setting of mold core 1 61 and mold core 2 62, that is, the mold core 6 is detachable.

[0066] Furthermore, the connection between mold core 1 61 and mold core 2 62 can be varied, including a structure of groove and protrusion 611, a snap-fit ​​structure, or other structures. The structure of groove and protrusion 611 is as follows: Figure 8 As shown, firstly, a connecting groove 621 is provided at one end of the mold core 2 62 near the mold core 1 61, and a groove rail 1 622 and a groove rail 2 623 are provided on the inner wall of the connecting groove 621. Moreover, one end of the groove rail 1 622 is open, and the other end of the groove rail 1 622 is connected to the groove rail 2 623. Furthermore, the groove rail 1 622 and the groove rail 2 623 are arranged vertically.

[0067] Meanwhile, a protrusion 611 is provided at the bottom of one end of mold core 61 located inside mold core 62. Therefore, in actual use, by inserting the protrusion 611 into the groove 622 through the opening of the groove 622 and moving it along the groove 622, and then rotating mold core 61, the protrusion 611 is moved along the groove 623, thereby connecting mold core 62 and mold core 61.

[0068] The snap-fit ​​structure is as follows: Figure 9 As shown, firstly, a connecting groove 621 is provided at one end of the mold core 2 62 near the mold core 1 61, and at least two connecting plates 612 are provided at one end of the mold core 1 61 located inside the mold core 2 62. Furthermore, a buckle 613 is provided on the outer side of the connecting plate 612 near the mold core 2 62, and a slot 624 is provided on the inner wall of the connecting groove 621 corresponding to the buckle 613.

[0069] Therefore, in actual use, since the connecting plate 612 is only connected at one end, the connecting plate 612 has a certain elasticity. So when the connecting plate 612 just enters the connecting groove 621, the two connecting plates 612 are squeezed by the inner wall of the connecting groove 621 and move closer to each other. When it moves to the slot 624, it expands outward and allows the buckle 613 to enter the slot 624.

[0070] Conversely, when separating, simply pull it outwards.

[0071] At the same time, when mold core 1 61 is connected to mold core 2 62, mold core 2 62 may move or rotate under force. Therefore, in order to prevent mold core 2 62 from moving, a limiting structure is set. That is, the preforming mold 5 includes a lower mold base 1 51 and an upper mold base 1 52, and the end of mold core 2 62 that extends out of the tube is a holding part 625. Moreover, a locking block is provided on the side of the holding part 625 near the lower mold base 1 51, and the lower mold base 1 51 is provided with a locking hole 511 corresponding to the locking block.

[0072] Therefore, in actual use, the card hole 511 and the card block are matched to limit the second mold core 62, thereby preventing the second mold core 62 from rotating or moving when connected with the first mold core 61.

[0073] At the same time, the matching of the card slot 511 and the card block also serves to indicate that the movement has been completed.

[0074] like Figures 2-4 As shown, the processing equipment corresponding to a simulated oil injection pipe processing technology can have the following structure: a processing equipment for processing pipes and including a work platform 10, wherein the work platform 10 is provided with a clamping device 2, a pipe shrinking device 3 and a stamping device 4, and the stamping device 4 includes a pre-forming mold 5 and an R-arc forming mold 7.

[0075] Meanwhile, the clamping device 2 is located between the tube shrinking device 3 and the stamping device 4 and includes a mounting base 21 and a clamping head 22. The clamping head 22 is rotatably mounted on the mounting base 21, and the mounting base 21 is movably mounted on the work platform 10.

[0076] Furthermore, the stamping device 4 includes a movable punch 41, and the preforming mold 5 includes a lower mold base 51 and an upper mold base 52, and the R-arc forming mold 7 includes a lower mold base 71 and an upper mold base 72. The back of the upper mold base 52 is connected to the back of the upper mold base 72 to form a combined mold base and is rotatably mounted on the punch 41. The lower mold base 71 is located inside the lower mold base 51. The lower mold base 51 includes a front mold base 512 and a rear mold base 513. Both the front mold base 512 and the rear mold base 513 are movably mounted on the working platform 10 and move outward or inward synchronously, thereby exposing or covering the lower mold base 71.

[0077] Therefore, in actual use, this processing equipment can realize the processing technology of imitation oil injection pipe. Moreover, by setting up a combination mold base, and by having the front mold base 512 and the rear mold base 513 move outward or inward simultaneously to expose or cover the lower mold base 71, the pre-forming mold 5 can be transformed into an R-arc processing mold 7. This eliminates the need to replace the mold by disassembly and installation, making it more convenient.

[0078] The tube shrinking device 3 is a conventional structure, and the present invention does not modify its structure, so it is not described in detail.

[0079] Secondly, the gripping head 22 is a pneumatic finger, which is an actuator that uses compressed air as power to grip or grasp workpieces. A rotary cylinder 23 is provided between the gripping head 22 and the mounting base 21, and the rotary cylinder 23 is used to drive the gripping head 22 to rotate.

[0080] Furthermore, the movable structure of the mounting base 21 is provided with a sliding groove on the working platform 10, and the mounting base 21 has grooves on both sides that are adapted to the sliding groove to achieve movement.

[0081] Then the rotation structure between the combined mold base and the punch 41 is as follows: First, side plates 43 are provided on both sides of the punch 41, and the combined mold base is set between the two side plates 43 through a rotating shaft. The rotating shaft is connected to a motor 44, and the rotating shaft is driven by the motor 44 to drive the combined mold base to rotate.

[0082] Furthermore, to prevent wear during rotation, the outer contour can be rounded.

[0083] Secondly, to prevent left and right swaying after rotation, a pressing block 42 can be set to limit the combination mold base. The specific structure is as follows: First, the punch 41 is provided with a movable pressing block 42 above the combination mold base, and the pressing block 42 abuts against the combination mold base to limit the combination of the combination mold base, and the pressing block 42 moves up and down as the combination mold base rotates.

[0084] Meanwhile, there is a spring between the punch 41 and the pressing block 42, which has a buffering effect to prevent the pressing block 42 from colliding with the inner wall of the punch 41 and causing wear.

[0085] like Figures 2-4 As shown, the relevant structure of the mold core 6 is as follows: First, a movable seat 9 is movably set on the working platform 10, and the mold core 6 is set on the movable seat 9. The mold core 6 includes a first mold core 61 and a second mold core 62, and the movable seat 9 is provided with a first movable seat 91 and a second movable seat 92 corresponding to the first mold core 61 and the second mold core 62.

[0086] Simultaneously, movable base 1 91 and movable base 2 92 move back and forth synchronously on the working platform 10, with mold core 1 61 moved and set on movable base 1 91, and mold core 2 62 moved and set on movable base 2 92.

[0087] Therefore, in actual use, the front and rear positions of the mold core 6 are confirmed by the synchronous movement of the first movable seat 91 and the second movable seat 92, and the left and right positions are determined by the movement of the first mold core 61 and the second mold core 62 themselves, so that one end of the two is placed in the tube 1 and connected inside the tube 1.

[0088] Furthermore, when mold core 1 61 and mold core 2 62 are automated rather than manual, the connection between them can be a snap-fit ​​structure. At the same time, the moving structure of moving seat 1 91 and moving seat 2 92 can refer to the mounting seat 21, that is, the working platform 10 is provided with a sliding groove, and the two sides of moving seat 1 91 and moving seat 2 92 are provided with grooves that are adapted to the sliding groove to achieve movement.

[0089] Furthermore, the structures of mold core 61 being movably mounted on movable seat 91 and mold core 62 being movably mounted on movable seat 92 are similar, namely, they adopt the form of a track and a cylinder. Specifically, a cylinder 3 94 connected to mold core 61 is provided on one side of movable seat 91, and a track is provided on the top of movable seat 91. Mold core 61 is driven to move along the track by cylinder 3 94.

[0090] Meanwhile, a cylinder 4 95 connected to the mold core 2 62 is provided on one side of the movable seat 2 92, and a track is provided on the top of the movable seat 2 92, so that the mold core 2 62 can be driven to move along the track by the cylinder 4 95.

[0091] like Figures 2-6As shown, the various devices have a linkage structure, which is as follows: First, a synchronization component 8 is provided at the bottom of the working platform 10, and the synchronization component 8 includes a pulley group 1 81, a pulley group 2 82 and a rack group 83. The pulley group 2 82 is connected to the cylinder 2 84. The pulley group 1 81 is connected to the mounting base 21 and is used to drive the mounting base 21 to move. The pulley group 2 82 is connected to the movable base 2 92 and is used to drive the movable base 2 92 to move. The rack group 83 is connected to the rear mold base 513 and is used to drive the rear mold base 513 to move.

[0092] Meanwhile, pulley group 1 81 includes pulley 1 811, pulley group 2 82 includes pulley 2 821, and rack group 83 includes gear 1 831. Moreover, pulley 1 811, pulley 2 821 and gear 1 831 are located on the same axis, and pulley 2 821 is located between pulley 1 811 and gear 1 831.

[0093] Furthermore, a connecting rod 85 is provided between pulley 811 and gear 831, and a cylinder 86 is provided between gear 831 and the working platform 10. Therefore, in actual use, when cylinder 86 drives gear 831 downward and pulley 811 moves downward, pulley 821 and gear 831 are connected and rotate synchronously; when cylinder 86 drives gear 831 upward and pulley 811 moves upward, pulley 821 and pulley 811 are connected and rotate synchronously.

[0094] Therefore, by setting the synchronization component 8, the pulley 2 821 and gear 1 831 can rotate synchronously or the pulley 2 821 and pulley 1 811 can rotate synchronously, that is, the clamping device 2 and the mold core 6 can move synchronously or the lower mold base 1 52 and the mold core 6 can move synchronously, thereby avoiding interference between the various components and reducing the processing time.

[0095] Here, the cylinder 86 drives only a small range of movement, which can be achieved simply by separating. Moreover, the closed structure also has a corresponding structure, which is as follows: First, the bottom of the working platform 10 is provided with a mounting shaft 87, and the gear 831 passes through the shaft 831, and the shaft 831 is movably mounted on the mounting shaft 87.

[0096] Furthermore, pulley 811 is fitted with shaft 812, and pulley 821 is fitted with shaft 822. Both ends of shaft 822 are connected to and separated from shaft 812 and shaft 831, respectively. When connected, a plug-in connection is used to ensure the alignment of the shafts.

[0097] like Figure 5As shown, the synchronization structure between movable seat 1 91 and movable seat 2 92 is as follows: First, a synchronization rod 93 is provided between movable seat 1 91 and movable seat 2 92, and the synchronization rod 93 is used to drive movable seat 1 91 and movable seat 2 92 to move synchronously. Furthermore, a cylinder 2 84 is provided on one side of both movable seat 1 91 and movable seat 2 92, and the cylinder 2 84 is used to drive movable seat 1 91 and movable seat 2 92 to move.

[0098] Therefore, in actual use, cylinder 84 is provided on both sides of moving seat 1 91 and moving seat 2 92. The purpose of setting two cylinders 84 is to ensure a larger thrust, thereby better driving the subsequent movement. Since only the rods are synchronously connected, the two cylinders 84 can ensure the stability of synchronous movement.

[0099] like Figure 5 As shown, the synchronization structure between the front mold base 512 and the rear mold base 513 is as follows: First, a gear 20 is provided at the bottom of the working platform 10, and the bottom of the front mold base 512 passes through the working platform 10 and a rack 514 is provided on the gear 20. The bottom of the rear mold base 513 passes through the working platform 10 and a rack 515 is provided on the gear 20. The rack 514 and the rack 515 mesh with the two sides of the gear 20 respectively.

[0100] Therefore, in actual use, the front mold base 512 and the rear mold base 513 can be moved synchronously by rotating gear 20. Moreover, the moving structure of the front mold base 512 and the rear mold base 513 can refer to the mounting base 21, that is, the working platform 10 is provided with a sliding groove, and the front mold base 512 and the rear mold base 513 are provided with grooves on both sides to match the sliding groove so as to realize the movement.

[0101] Finally, corresponding to the processing equipment mentioned above, the processing technology can be specifically described as follows:

[0102] S1: Place the cut pipe 1 into the clamping device 2, with one end of the pipe 1 inside the shrinking device 3, and start the shrinking device 3 to shrink the pipe.

[0103] S2: The tube 1 after shrinking is placed into the pre-forming mold 5 on the stamping device 4. That is, the clamping head 22 on the clamping device 2 rotates and the mounting base 21 moves, thereby driving the tube 1 to move onto the lower mold base 51 of the pre-forming mold 5.

[0104] Furthermore, at this time, pulley 811 and pulley 821 are connected, meaning that when clamping device 2 moves, mold core 6 moves synchronously, thus avoiding interference. Also, upper mold base 52 is positioned downwards.

[0105] Secondly, after the tube 1 is placed, a mold core 6 needs to be placed inside the tube 1. At this time, the clamping device 2 will move away and reset, and the mold core 6 will move synchronously until it reaches both sides of the lower mold base 51. Then, the mold core 61 and the mold core 62 will move towards the lower mold base 51, so that one end of the mold core 61 and the mold core 62 is located inside the tube 1 and connected to the inside of the tube 1. Then, the stamping device 4 will be started to perform pre-forming.

[0106] S3: Remove the mold core 6, that is, move the mold core 1 61 and the mold core 2 62 away from the lower mold base 51, thereby separating the mold core 1 61 and the mold core 2 62 from the tube 1.

[0107] Then, cylinder 86 drives and connects gear 831 and pulley 821. At this time, the mold core 6 and lower mold base 51 move, thus exposing the lower mold base 71, and the tube 1 falls to the lower mold base 71 of the R-arc forming mold 7 under the action of gravity.

[0108] Furthermore, the combined mold base rotates so that the upper mold base 2 72 faces downwards, and the stamping device 4 is activated to perform R-arc processing.

[0109] S4: Polishing.

[0110] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. However, the present invention is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of the present invention, and all such changes and modifications fall within the scope of the claimed invention.
