Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 to 7, in some embodiments of the present invention, a processing apparatus for a reducing tee joint is disclosed, comprising: the three-way connector comprises a base 1, a placing table 33 for placing the three-way connector 8, a first slide rail 6 and a second slide rail 7 perpendicular to the first slide rail 6.
The placing table 33 is arranged in the middle of the upper end face of the base 1, and the first slide rail 6 and the second slide rail 7 are symmetrically arranged on the upper end face of the base 1 and are positioned on two sides of the placing table 33.
The first sliding rail 6 is connected with a forging mechanism and the first sliding table 2 in a sliding mode, and the first sliding table 2 is connected with a spraying mechanism for spraying the three-way joint 8 in a sliding mode.
And a trimming mechanism for trimming the end part of the three-way joint 8 is connected onto the second slide rail 7 in a sliding manner.
The two sides of the placing table 33 are provided with dies for forging and forming.
In general, various hardware in the present embodiment can be performed in accordance with the following steps. First, it is necessary to place a blank of three-way piping on the placement stage 33 of the base 1, and then place and fix a mold so that the mold clamps and fixes the blank. The forging mechanism is slid so that the forging mechanism is aligned with both ends of the main pipe 801 of the three-way joint 8. Then the three-way joint 8 can be punched or forged, the two ends of the die are in an opening shape or the shape of the end head of the forging mechanism corresponds to the opening shape, so that after the three-way joint 8 is punched or forged, the end part of the three-way joint 8 can be in a flaring shape, and the variable-diameter processing and forming are realized.
At this point, the forging mechanism is moved again so that it slides away from the tee 8. And the sliding table I2 enables the spraying mechanism to be close to the three-way joint 8 and sprays the diameter-variable part of the three-way joint 8. The paint can be molten metal material to relieve the thinning of the pipe wall caused by reducing processing, and on the other hand, the wear resistance, corrosion resistance and other performances of the end part can be enhanced (depending on the characteristics of the paint).
The blank in this embodiment refers to a tee 8 or pipe that has been preliminarily formed, primarily in the form of a tee. The forming step of the preamble may be injection molding.
In some preferred embodiments of the invention, the forging mechanism includes a hydraulic actuator 13 and a punch head 11 driven by the hydraulic actuator 13. The die comprises an upper die 9 and a lower die 10, wherein the outer ends of the upper die 9 and the lower die 10 are respectively provided with a flaring, and the shape of the flaring is matched with the end part of the punch. The upper die 9 is provided with a through hole, one side of the upper die 9 far away from the placing table 33 is provided with a punch head two 12, and the punch head two 12 is in sliding connection with the upper end face of the base 1. One end of the second punch 12 can pass through the through hole to punch the branch pipe 802 of the three-way joint 8.
When the upper die 9 needs to be transferred, the operation can be performed manually, or a traction rope can be connected between the punch head II 12 and the upper die 9. When the punch II 12 and the punch I11 are transferred uniformly, the fixed connection between the upper die 9 and the base 1 or the lower die 10 is released, and the upper die 9 is pulled to transfer by the movement of the punch II 12.
In this embodiment, a specific structure of the forging mechanism and the die is provided, and the forging mechanism and the die are operated by the following method. First, the three-way joint 8 is placed on the placing table 33, and the upper die 9 and the lower die 10 clamp and fix the three-way joint 8 from both sides, respectively. It is noted that the upper die 9 and the lower die 10 fix the end of the three-way joint 8, and the placement table 33 is used for supporting the middle of the three-way joint 8 and is supported on two sides of the branch pipe 802 of the three-way joint 8, so that the die and the placement table 33 do not interfere, but mutually cooperate to fix the three-way joint 8.
During machining, the hydraulic driver 13 is slid so that the first punch 11 approaches the three-way joint 8, and then the first punch 11 is driven to punch two ends of the main pipe 801 of the three-way joint 8. The first punch 11 corresponds to the end parts of the upper die 9 and the lower die 10, and the end part of the three-way joint 8 is outwards expanded by the punching of the first punch 11 and is attached to the shape of the die, so that the reducing processing of the end part of the main pipeline 801 of the three-way joint 8 is completed.
The diameter-changing process of branch pipe 802 may be performed by a through hole on the outer side of upper die 9. Specifically, the second punch 12 is driven to punch the orifice of the branch pipe 802 through the through hole of the upper die 9, thereby expanding the diameter of the branch pipe 802.
In other more specific embodiments, the first punch 11 and the second punch 12 may be moved synchronously. Specifically, a rod 34 may be disposed between the first punch 11 and the second punch 12, one end of the rod 34 is hinged to the first punch 11, and the other end of the rod 34 is hinged to the second punch 12. When the first punch 11 is driven, the second punch 12 can be synchronously driven to move by the rod 34, so that the first punch 11 and the second punch 12 can alternately punch the three-way joint 8.
When the forging mechanism needs to be removed, the hydraulic driver 13, the first punch 11 and the second punch 12 are synchronously moved to be far away from the three-way joint 8 and the upper die 9. The working position is vacated for the spraying mechanism.
In some preferred embodiments of the invention, the spraying mechanism comprises a motor 4, an arcuate plate 19 and a sprayer disposed on the inner wall of the arcuate plate 19. The inner wall of the arc-shaped plate 19 is matched with the outer wall of the three-way joint 8. The outer wall of the arc-shaped plate 19 is fixedly connected with a connecting rod 18, and the other end of the connecting rod 18 is fixedly connected with a belt pulley I21. One side of the first slide rail 6 is provided with a screw rod 14 parallel to the first slide rail 6, and the screw rod 14 penetrates through the first slide table 2 and is in threaded connection with the first slide table 2. The two ends of the screw 14 are rotatably connected with the base 1. One end of the screw 14 is coaxially and fixedly connected with a worm 15, a worm wheel 16 is meshed below the worm 15, a belt wheel II 22 is coaxially and fixedly connected with the worm wheel 16, and a belt wheel I21 is in transmission connection with the belt wheel II 22 through a transmission belt 20. The motor I4 is in sliding connection with the sliding table I2, a tensioning head 17 is fixedly arranged on an output shaft of the motor I4, and the tensioning head 17 can be inserted into and pressed on the end part of the three-way joint 8 along with the motor I4 in a sliding manner.
The connecting rod 18, the fixer and the arc plate 19 are accommodated below the base 1, and the base 1 is provided with a through groove for the connecting rod 18, the fixer and the arc plate 19 to rotate.
The embodiment relates to a specific spraying mechanism and a specific structure thereof. In the initial state, the spraying mechanism is not aligned with the three-way joint 8, after the forging mechanism finishes working, the forging mechanism is moved, and then the screw 14 is rotated to drive the sliding table I2 to translate, so that the motor I4 is close to the three-way joint 8. Then, the position of the motor I4 is adjusted so that the tensioning head 17 of the motor I4 is pressed in the holes at the two ends of the three-way joint 8.
Simultaneously with the rotation of the screw 14, the worm 15 is synchronously driven to rotate, and the worm 15 drives the worm wheel 16 to rotate. The worm wheel 16 synchronously drives the first belt wheel 21 and the second belt wheel 22 to rotate, so as to drive the connecting rod 18 to rotate, so that the arc plate 19 rotates upwards from the inside of the base 1, and when the screw 14 rotates to enable the first sliding table 2 to be in place, the arc plate 19 is exactly covered on the side wall of the three-way joint 8. Thus, when the first sliding table 2 is adjusted to be in place, the arc-shaped plate 19 can be automatically adjusted to the expected position.
It should be noted that in this embodiment, the upper die 9 is removed before the spraying operation, and the curved plate 19 turned in place is engaged with the lower die 10, and the placement table 33 is added to limit the position of the three-way joint 8.
In summary, after each component is adjusted in place, the motor one 4 starts to rotate, and the tensioning heads 17 pressed at two ends of the three-way joint 8 drive the three-way joint 8 to rotate. The first motor 4 is started, and the sprayer on the arc plate 19 begins to spray the material for strengthening to the outer wall of the rotating three-way joint 8, which can be a metal material or a nonmetallic material.
In some preferred embodiments of the present invention, the trimming mechanism includes a second slipway 3, a mounting frame 23, a second motor 5 and a first cutter 27.
The second sliding table 3 is in sliding connection with the second sliding rail 7, and the second motor 5 is in sliding connection with the second sliding table 3.
The mounting frame 23 is arranged on the outer wall of the second motor 5, and the mounting frame 23 is rotatably connected with a sun gear 24. An inner gear 26 is arranged on the outer side of the sun gear 24, a plurality of planetary gears 25 are arranged between the inner gear 26 and the sun gear 24, and the planetary gears 25 are meshed with the inner gear 26 and the sun gear 24 respectively. The first cutter 27 is fixedly mounted on the planetary gear 25. The ring gear 26 is fixedly mounted on the mounting frame 23. The sun gear 24 is fixedly connected with the output shaft of the second motor 5.
In the preliminary stamping or forging process, defects such as unexpected deformation or burrs may be generated, and particularly when the inner wall of the pipeline is not round, the technical problem of difficult assembly is easily caused. In the present embodiment, a specific trimming mechanism is provided to overcome the above technical problems.
Specifically, after the stamping of the three-way joint 8 and the spraying of the outer wall are completed, the first slide table 2 is moved to vacate the machining position, and the second slide table 3 is slid so that the mounting frame 23 and the first cutter 27 thereon are brought close to both ends of the main pipe 801 of the three-way joint 8.
In the working process, the second motor 5 is started to drive the central gear 24 on the driving shaft of the second motor 5 to rotate, and the planetary gear 25 rotates around the central gear 24 and simultaneously the planetary gear rotates due to the fact that the internal gear 26 is fixed. Therefore, the cutter also rotates along the inner wall of the main pipe 801 and rotates together with the planetary gears 25. Finally, the rotary polishing and finishing of the inner wall of the main pipeline 801 of the three-way joint 8 are completed under the drive of the motor II 5.
