Description

Technical Field

[0001] The invention relates to an integrated machine for squeezing and flattening pipe ends used in the technical field of pipe fitting processing. Background Art

[0002] With the growth of technology, metal pipe fittings are widely used in the fields of air conditioners, refrigerators and refrigeration equipment, auto parts, etc. The corresponding pipe fittings need to go through multiple processes to complete the processing operation during the processing. Usually, the staff will transport the cut pipe fittings to the pipe end processing mechanism, and the pipe end processing mechanism will expand or reduce the pipe mouth according to the needs of the customer, and then the staff will recycle the pipe fittings with the processed pipe mouth to the material frame. Then it will be transported to the subsequent chamfering operation through the material frame. After the chamfering is completed, it will continue to be recycled to the material frame, and then transferred to the subsequent pipe flattening mechanism for the flattening operation of the pipe fitting. This process is cumbersome and requires transfer operations at each station, and each process requires manual assistance, which leads to a large number of workers. This production process wastes manpower, reduces production efficiency, directly increases production costs, and is not conducive to automated production processes. In addition, the mold of the flattening mechanism squeezes the pipe fittings on both sides, and the pipe fittings are pressed into the desired shape by applying extrusion force on both sides. If the pipe is round, the middle will be stressed first when the extrusion force is applied, which will easily lead to the concave core of the pipe during the production process, causing damage to the pipe and a high failure rate, which will increase the cost and be detrimental to the stable production process. At the same time, the concave core condition also limits the operable length of the flattening mechanism on the pipe, narrowing the production application range of the mechanism.

DETAILED DESCRIPTION

[0036] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0037] like Figure 1 As shown, the overall structure of the device includes a feeding mechanism 1, a processing mechanism and a discharging mechanism 7. The processing mechanism is arranged on a workbench 21 of a frame 2. Figure 3 As shown, the frame 2 is constructed by profiles to form a frame, and then a workbench 21 is constructed at the profile position of the corresponding height. The workbench 21 is a metal panel, thereby ensuring the stable setting of the processing mechanism. Figure 2 As shown, the loading mechanism 1 is located on one side of the frame 2, thereby realizing the loading operation of the pipe fittings and making them reach the corresponding processing position. The discharging mechanism 7 is located on the other side of the frame 2, and the connection between the discharging mechanism 7 and the processing position is set to a matching height, thereby ensuring the effective storage operation of the processed pipe fittings.

[0038] like Figure 5As shown, the device is connected by profiles to form a feeding mechanism 1. The feeding mechanism 1 is provided with a material warehouse 11 for placing pipe fittings, and the staff can pour a large number of pipe fittings into the material warehouse 11. At this time, the material warehouse 11 is provided with a material distribution structure 12 on one side parallel to the axis of the pipe fittings. A pipe fitting placement position is provided above the material distribution structure 12, and a feeding drive cylinder 14 for driving the pipe fitting placement position to move up and down is provided below the material distribution structure 12. At this time, the bottom of the material warehouse 11 is set to be inclined toward the material distribution structure 12. When the feeding drive cylinder 14 drives the pipe fitting placement position of the material distribution structure 12 to be equal to or lower than the bottom surface of the material warehouse 11, the pipe fitting rolls down to the pipe fitting placement position under the action of gravity. The width of the pipe fitting placement position is set to allow only one pipe fitting to be placed. When the material distribution structure 12 moves upward under the action of the feeding drive cylinder 14, the excess pipe fittings fall back to the material warehouse 11 due to the lack of stable supporting force, thereby realizing the material distribution operation and taking a pipe fitting. The dividing structure 12 is provided with a plurality of baffles on the side facing the material storage 11. When the dividing structure 12 moves upward under the action of the feeding drive cylinder 14, the pipe placement position is higher than the bottom surface of the material storage 11, and the corresponding baffle is located on the side of the material storage 11 facing the dividing structure 12, thereby restricting the pipes in the material storage 11 and preventing them from falling. While enhancing the stability of the dividing structure 12, the setting of additional baffles is avoided, the production cost is reduced, and the production process is stably implemented. At the same time, the dividing structure 12 is provided with a feeding positioning structure 13 on the opposite side of the material storage 11. In order to ensure the stable storage of the pipes on the dividing structure 12, the pipe placement surface is set to be inclined toward the feeding positioning structure 13. When the pipe placement surface is located below the feeding positioning structure, the side plate of the feeding positioning structure 13 cooperates with the pipe placement surface to form a groove for stable placement of the pipes, thereby ensuring the stable setting of the pipes. The pipe placement surface can be as follows Figure 6The figure shows the installation of the material dividing wedge block 18 at the same angle. When the pipe placement surface of the material dividing structure 12 is located above the material feeding positioning structure 13 under the action of the feeding drive cylinder 14, the pipe rolling to the positioning surface of the material feeding positioning structure 13 under the action of gravity. The positioning surface is provided with a plurality of V-shaped wedge blocks, which are positioning support blocks 16, and the V-shaped wedge blocks are arranged along the axis of the pipe. When the pipe rolls down to the positioning surface, the pipe is located in the V-shaped groove of the V-shaped wedge block, thereby limiting the position of the pipe. The two ends of the pipe are respectively provided with a fixing member 15 and a material feeding positioning cylinder 17, and the fixing member 15 is provided with a fixing rod facing the pipe, and the diameter of the fixing rod is consistent with the diameter of the pipe. At the same time, the material feeding positioning cylinder 17 can reciprocate along the axial direction of the pipe. The positioning surface is provided with a detection device, and the detection device can use a reflective photoelectric sensor. The photoelectric sensor is arranged on one side of the positioning support block 16, and its emission source is arranged upward. When a pipe is located on the positioning support block 16, the outer surface of the pipe is located above the emission source, thereby forming a reflector. The light emitted by the emission source is reflected by the outer surface of the pipe, and the receiver receives the propagation of the light. At this time, the photoelectric signal of the corresponding photoelectric sensor changes, thereby realizing the detection process. When it is detected that a pipe is located on the positioning support block 16, the feeding positioning cylinder 17 moves toward the end of the pipe, thereby fixing the pipe between the feeding positioning cylinder 17 and the fixing member 15.

[0039] The feeding positioning cylinder 17 and the fixing member 15 define the left and right positions of the pipe fittings, and the positioning support block 16 limits the left and right positions of the pipe fittings. The above structures cooperate to realize the positioning operation of the pipe fittings, thereby providing a guarantee for the stable progress of subsequent work. Figure 4 As shown, a top frame 22 is installed on the frame 2 through a profile, and the top frame 22 is parallel to the workbench 21. Two manipulator running tracks 25 are arranged in parallel on the top frame 22, and the manipulator running tracks 25 are perpendicular to the axis of the loading positioning structure 13, that is, perpendicular to the axis of the pipe. The manipulators 24 are arranged in pairs, and during the clamping process, the two opposing manipulators 24 clamp the two ends of the pipe respectively, which effectively ensures the clamping quality and avoids damage to the pipe due to the unbalanced state of transportation. Figure 7 As shown, the setting direction of the processing mechanism is parallel to the direction of the feeding positioning mechanism 13, that is, the axis of the processing mechanism is perpendicular to the robot running track 25. Under the driving action, the robot 24 clamps the two ends of the pipe fitting at the feeding positioning structure 13 respectively, and moves along the robot running track 25 to the top of the pipe mouth processing mechanism. Figure 4As shown, the top frame is provided with an adjustment track 26 perpendicular to the manipulator motion track 25, and the manipulator running track 25 on one side is located on the adjustment track 26. The manipulator running track 25 on this side can move along the adjustment track 26 toward the manipulator running track 25 on the other side, so that the manipulator 24 provides guarantee for the gripping quality of the pipe fittings, thereby expanding the production application scope of the pipe fittings.

[0040] like Figure 8 As shown, the pipe mouth processing mechanism includes two pipe mouth clamping mechanisms 93 for fixing the pipe fittings and a pipe mouth processing mechanism 94 arranged on one side of the pipe mouth clamping mechanism 93. The pipe mouth processing mechanisms 94 are respectively arranged on the far side of the pipe mouth clamping mechanism 93. The manipulator 24 descends to the pipe mouth clamping mechanism 93 under the action of the control cylinder, so that the two ends of the pipe fitting are located in the positioning area of ​​the pipe mouth clamping mechanism 93, and the two ends of the pipe fitting are facing the pipe mouth processing mechanism 94. One pipe mouth processing mechanism 94 is fixed to the workbench 21 by screws, and the other pipe mouth processing mechanism 94 is fixed to the processing moving plate by screws. The workbench 21 is provided with a track parallel to the axis of the pipe fitting at the corresponding position, and the workbench 21 is fixed with a driving screw for driving the processing moving plate to reciprocate along the track. After the pipe fitting is placed on the pipe mouth clamping mechanism 93, the driving screw drives the processing moving plate to move toward the pipe fitting, so that the pipe mouths at both ends are located in the pipe mouth processing unit 94, so that the pipe mouths at both ends can be processed at the same time. In addition, when it is necessary to process the pipe mouth at one end, the workbench 21 installs the pipe mouth processing unit 94 at one end, or drives the pipe mouth processing mechanism 94 at one end during the processing, and the pipe mouth processing unit 94 corresponding to the pipe mouth end that does not need to be processed does not work. The processing moving plate realizes the advance and retreat of the pipe mouth processing unit 94 to facilitate the pipe mouth processing unit 94 to process the pipe mouth of the pipe fitting. At this time, the pipe mouth processing unit 94 can select the corresponding processing mechanism for shrinking or expanding according to customer needs, and set the processing parts of the pipe mouth processing unit 94 according to production needs. As shown in the figure, the pipe mouth processing mechanism is sequentially set as a pipe mouth reduction mechanism 3 and a pipe mouth expansion mechanism 4, and the pipe mouth expansion mechanism 4 is set as two groups, thereby expanding its scope of application and ensuring the use effect. The movement of the corresponding pipe fittings can be achieved accurately through the control operation of the robot 24, effectively ensuring the processing requirements.

[0041] The pipe fitting after the pipe mouth processing is moved to the chamfering clamping mechanism 51 of the chamfering processing mechanism 5 under the action of the manipulator 24. The chamfering clamping mechanism 51 is provided with a pipe mouth limiting area, thereby realizing the limitation of the position of the pipe fitting. Chamfering processing units 52 are respectively provided at both ends of the chamfering clamping mechanism 51. The two chamfering processing units 52 are respectively connected to the workbench 21 and the chamfering unit moving plate by screws. The workbench 21 is provided with a chamfering processing track along the axis of the pipe fitting, and the chamfering unit moving plate can realize the reciprocating motion of the chamfering processing unit 52 under the action of the driving mechanism. The chamfering processing unit 52 is provided with a chamfering knife for chamfering the pipe fitting and a chamfering knife driving device. Under the driving action, the chamfering processing unit 52 moves to the corresponding processing position, and the chamfering clamping structure clamps the pipe fitting, effectively ensuring the stability of the chamfering operation. At the same time, the chamfering mechanisms at both ends of the chamfering clamping structure perform chamfering operations on the two ends of the pipe fitting respectively. The frame 2 may be provided with a chamfering end travel switch for controlling the advance and retreat process of the chamfering cutter, thereby making the chamfering process more precise and improving the processing accuracy.

[0042] As shown in FIG. 7 , the moving parts of the pipe mouth processing mechanism and the chamfering processing mechanism 5 are both arranged on the same moving plate 9, and at this time, the moving plate 9 is connected to the nut of the moving plate driving screw 91, and the screw of the moving plate driving screw 91 is fixedly arranged on the workbench 21. When the driving motor drives the screw to rotate, the nut drives the moving plate 9 to realize the synchronous movement of the pipe mouth processing mechanism and the chamfering processing mechanism 5. Since the length specifications of the pipe fittings in the processing process are the same, the processing length is also certain, so the fixed setting of the pipe mouth processing mechanism and the chamfering processing mechanism 5 can meet the processing operation of the pipe fittings. This setting method effectively improves the processing efficiency of the pipe fittings and reduces the production cost. At the same time, it is conducive to the synchronous and steady progress of the pipe mouth structure and chamfering processing, and at the same time expands the scope of application of the equipment, ensuring the production quality of pipe fittings of different lengths. A moving plate motion track 92 is provided on the workbench 21, thereby limiting the moving direction of the moving plate 9, effectively improving the production accuracy and ensuring the production quality.

[0043] The chamfered pipe is moved to the pipe placement groove 611 of the flattening mechanism 6 by the robot 24. Fig. 9As shown, two relatively parallel extrusion plates 612 in the oil cylinder mold 61 form a pipe placement groove 611, and four extrusion cylinders 613 are evenly arranged at one end of the extrusion plate 612 away from the pipe placement groove 611. The fixed cylinder body of the extrusion cylinder 613 is fixedly connected to the workbench 21 by bolts, and the movable end is connected to the extrusion plate 612. At this time, when the pipe is placed in the pipe placement groove 611 along the axis, the extrusion cylinder 613 pushes the extrusion plate 612 to move relatively, and the pipe is flattened under the action of the extrusion force. The uniform arrangement of the extrusion cylinder 613 effectively ensures the overall extrusion effect of the pipe and the extrusion quality. The pipe placement groove 611 is provided with openings on both sides opposite to the extrusion plate 612, and the openings are respectively provided with core pulling mechanisms 62 along the axis. The core pulling mechanism 62 is provided with a core moving track 623 along the axis direction of the pipe placement groove 611. The core moving track 623 is fixedly mounted with a core driving cylinder 622 at the end away from the cylinder mold 61, and the moving end of the core driving cylinder 622 faces the pipe placement groove 611. Fig.11 As shown, the moving end of the core driving cylinder 622 is connected to a core fixing block 624, and the core fixing block 624 is connected to a long strip of core 621 facing the pipe placement slot 611. The setting of the core fixing block 624 improves the controllability of the core 621 and ensures the pushing effect. A matching groove matching the core moving track 623 is set below the core fixing block 624, and the core fixing block 624 reciprocates along the core moving track 623 under the driving action of the core driving cylinder 622. Fig.10As shown, at this time, the core moving track 623 is installed with a core positioning block 625 at the end near the pipe placement groove 611. The core positioning block 625 is provided with a core limiting groove, which prevents the end of the core 621 from sagging under the action of gravity and ensures the moving direction of the core 621. When the core 621 is moving, its end is always located in the core limiting groove of the core positioning block 625. After the manipulator 24 places the pipe in the pipe placement groove 611, the core driving cylinder 622 uses the moving end to push the core fixing block 624 with the core 621 to move. Under the pushing action, the core 621 moves to the inside of the through hole of the pipe. At this time, the core 621 of the core pulling mechanism 62 at both ends moves relatively synchronously until the core 621 at both ends moves to contact. At this time, the extrusion cylinder 613 drives the oil cylinder mold 61 to realize the pipe flattening operation. The sleeve of the core 621 on the pipe avoids the occurrence of a concave center condition of the pipe during the flattening operation, thereby ensuring the production quality. At the same time, the size of the core 621 can be set to the inner hole size required for the flattening operation, thereby ensuring the consistency and effectiveness of the production size and improving the production quality. The two ends of the core pulling mechanism 62 are set to improve the work efficiency of the core pulling operation, while ensuring the normal service life of the core 621 and the driving effectiveness of the core 621. At the same time, the setting of the core 621 increases the length of the processable pipe and ensures the flattening operation quality of pipes of various lengths. When performing a flattening operation on a shorter pipe, the single-sided drive installation setting of the core 621 can be used.

[0044] After the flattening operation is completed, the core 621 moves away from the pipe placement slot 611 under the action of the core driving cylinder 622, so that the core 621 moves out of the pipe. The squeezing cylinder 613 drives the squeezing plate 612 to move in the opposite direction of the pipe placement slot 611, so that the pipe is ready for picking up. At this time, the robot 24 clamps the flattened pipe to the discharging mechanism 7, as shown in FIG. Fig.12 As shown, the discharging mechanism 7 is formed by connecting a discharging inclined plate 71 and a discharging baffle 72. One end of the discharging inclined plate 71 is connected to the end of the workbench 21, and the other end of the discharging inclined plate 71 is tilted downward and faces the discharging receiving groove 73 located below. The finished pipe fittings move along the discharging inclined plate 71 to the discharging receiving groove 73. The discharging receiving groove 73 is set to have openings at both ends. When a certain number of pipe fittings are stored, the staff can push them into the transportation device. At the same time, the end of the discharging inclined plate 71 can be connected to a conveying device, and the conveying device is used to directly convey the pipe fittings that fall on it to the corresponding position. In order to ensure the transportation state of the pipe fittings on the discharging inclined plate 71, discharging baffles 72 are respectively installed at both ends of the discharging inclined plate 71, thereby limiting the conveying direction of the pipe fittings, avoiding the deviation of the trajectory during the movement of the pipe fittings, and ensuring the collection effect of the pipe fittings.

[0045] At the same time, the rack 2 is respectively provided with two control boxes 8 with the same functions, and the control boxes 8 are respectively arranged at different positions, so that the staff can control and operate the equipment at different positions. When the staff uses one of the control boxes 8 to control and operate the equipment, the other control box 8 cannot produce a control effect, which effectively guarantees the control effect, avoids the damage to the equipment control system caused by the synchronous issuance of multiple control signals, and guarantees the control effect. The setting of multiple control boxes 8 realizes multi-directional control and guarantees the control efficiency. At this time, the staff can select the control boxes 8 close to each other according to the control device, so that the staff can monitor the control device conveniently during the control process, and ensure the control quality. At the same time, the control boxes 8 can be set to four, three, etc. according to the needs. The control box 8 in the equipment controls the working state of each device in the equipment through the servo system, and the servo system can accurately follow or reproduce the feedback control system of a process. The servo system makes the state of the system reach or approach a predetermined value, and can compare the required state with the actual state, and adjust the automatic control system of the control component according to their difference, which effectively guarantees the stability of the system control and guarantees the control processing effect. At the same time, the servo system is small in size, which reduces the space occupancy rate of the device. At the same time, the system consumes less energy when not working, effectively ensuring the rational use of resources, reducing energy consumption, and avoiding the generation of idle consumption. In addition, the oil temperature changes less during the production process, reducing damage to the device, ensuring the normal use effect of the life, and reducing the generation of noise during the working process, preventing noise pollution to the external environment. Maintenance ladders 23 are set on both sides of the frame 2. When the processing mechanism is damaged, the staff can reach the required maintenance place through the maintenance ladder 23, which improves the maintenance efficiency.
