DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0037] See also Figure 1-Figure 8 In the embodiment of the present invention, the continuous shaping production equipment for the ports of automobile pipe fittings comprises a base 1, a receiving seat 2, a first shaping piece 21, a second shaping piece 22 and a material ejecting mechanism arranged on the base 1;

[0038] The receiving seat 2 is fixedly arranged on the base 1, and is used to prevent the pipe to be processed, and the base 1 is provided with a fastening mechanism for pressing and fixing the pipe located on the receiving seat 2, and the fastening mechanism can perform pressing and lifting actions;

[0039] The first shaping piece 21 and the second shaping piece 22 are movably arranged on the base 1 and connected to a hydraulic pushing mechanism installed on the base 1. The hydraulic pushing mechanism is used to drive the first shaping piece 21 and the second shaping piece 22 to move toward the pipe port in sequence so that the pipe port is deformed twice. The first shaping piece 21 and the second shaping piece 22 are also connected with a shifting mechanism. The shifting mechanism is triggered after each deformation of the port, and can cause the first shaping piece 21 and the second shaping piece 22 to move along the width direction of the base 1. The lifting mechanism is connected to a pipe transfer mechanism arranged on the base 1. The lifting mechanism and the pipe transfer mechanism are triggered when the fastening mechanism performs a lifting action. The lifting mechanism is used to lift the pipe on the receiving seat 2. The pipe transfer mechanism can be translated to the bottom of the pipe and then perform a swing action to allow the pipe to roll and transfer.

[0040] Among them, it is necessary to supplement that, in order to realize continuous production, in actual operation, the receiving seat 2 is connected to a corresponding automatic pipe feeder, and a conveyor belt is added to the side of the base 1 close to the pipe transfer mechanism, and the conveyor belt is used to transport the processed pipes. After the pipe transfer mechanism is translated to the bottom of the raised pipe, it swings upward, so that the pipe located on the lifting mechanism will be separated from the lifting mechanism, and the pipe will roll along the pipe transfer mechanism which is in an inclined state at this time to the conveyor belt. After the lifting mechanism is reset, the automatic feeding mechanism will replenish the pipes to be processed on the receiving seat 2;

[0041] Secondly, in the actual pipe port shaping process, in order to avoid excessive deformation of the pipe end and affect the processing accuracy, two shaping molds (i.e., the first shaping part 21 and the second shaping part 22) are usually required to process the pipe end successively, that is, the pipe shaping process is carried out in two steps.

[0042] During processing, the fastening mechanism presses down and fixes the pipe on the receiving seat 2. At first, the first shaping piece 21 corresponds to the pipe, and the hydraulic pushing mechanism works to drive the first shaping piece 21 and the second shaping piece 22 to move along the length direction of the base 1. Then, the first shaping piece 21 acts on the end of the pipe, and the pipe completes the first deformation. Subsequently, the hydraulic pushing mechanism drives the first shaping piece 21 and the second shaping piece 22 to return and reset. During this process, after the first shaping piece 21 is separated from the end of the pipe, the transposition mechanism is triggered to drive the first shaping piece 21 and the second shaping piece 22 to move along the width direction of the base 1 until the second shaping piece 22 corresponds to the pipe. Then, the hydraulic pushing mechanism repeats the reciprocating work once more, and the second shaping piece 22 can perform secondary shaping on the end of the pipe, and the pipe completes the second deformation.

[0043] Then, the fastening mechanism is lifted up, so that the fixed state of the processed pipe fittings on the receiving seat 2 is released. In the latter part of the lifting stroke of the fastening mechanism, the lifting mechanism will lift the pipe fittings on the receiving seat 2, and the pipe fittings will be separated from the receiving seat 2. At the same time, the material transfer mechanism moves toward the bottom of the pipe fittings. After the lifting of the pipe fittings is completed, the material transfer mechanism reaches the bottom of the pipe fittings and swings upward, so that the pipe fittings roll down along the material transfer mechanism in an inclined state, realizing the automatic transfer function of the pipe fittings. Finally, the fastening mechanism gradually moves downward again, prompting the lifting mechanism and the material transfer mechanism to reset, so as to add the pipe fittings to be processed to the receiving seat 2.

[0044] In summary, when the device is working, the fastening mechanism is used to fix the pipe fitting, and the hydraulic pushing mechanism is used to drive the first shaping member 21 and the second shaping member 22 to act on the end of the pipe fitting in turn, so that the pipe fitting is deformed twice in turn, and after each deformation of the pipe fitting, the transposition mechanism can drive the first shaping member 21 and the second shaping member 22 to move along the width direction of the base 1 to realize automatic switching of the two shaping sequences. In addition, after the shaping is completed, when the fastening mechanism performs the lifting action, the jacking mechanism can lift the pipe fitting, and the material transfer mechanism is used to transfer the pipe fitting. Therefore, through the mutual cooperation and mechanical interlocking between various mechanisms and components, the degree of automation of the pipe shaping process is greatly improved. In actual production, the use of sensor components can be reduced or the control program can be effectively simplified, so that the operation of the equipment has higher stability and lower failure rate, which is suitable for popularization and use.

[0045] Please refer again Figure 1 and Figure 2 A vertical plate 3 is installed on the base 1, and the fastening mechanism includes an assembly plate 6 slidably arranged on the vertical plate 3, a fastener 7 fixed to the assembly plate 6 and located above the receiving seat 2, and a first hydraulic cylinder 4 installed on the base 1, the movable end of the first hydraulic cylinder 4 is fixed to the assembly plate 6, and a driving wheel 8 is installed on the side of the assembly plate 6 away from the fastener 7, and the driving wheel 8 cooperates with the material transfer mechanism.

[0046] During operation, the first hydraulic cylinder 4 drives the assembly plate 6 to slide downward on the vertical plate 3. In the first stroke of this process, the lifting mechanism in the lifted state moves down and resets to ensure the flatness of the receiving seat 2 during subsequent loading, and the material transfer mechanism can also move away from the receiving seat 2 and reset to ensure the smooth progress of subsequent loading. Subsequently, the pipe fittings to be processed can be transported to the receiving seat 2, and the fasteners 7 press the pipe fittings on the receiving seat 2.

[0047] Please refer again Figure 6 and Figure 7 The material transfer mechanism includes a follower structure provided on the base 1 and a movable arm group connected to the follower structure, and the follower structure cooperates with the driving wheel 8 and is also connected to the ejecting mechanism. The follower structure includes a connecting plate 9 slidably provided on the base 1, the connecting plate 9 is connected to an elastic component provided at the bottom of the base 1, and one end of the connecting plate 9 is formed with a protrusion abutting against the driving wheel 8, and the other end is slidably sleeved with a driven plate 13, the driven plate 13 is connected to the movable arm group, and the protrusion is provided with an inclined surface 901. A first boss 1301 is provided on both sides of the driven plate 13, and two first limit plates 14 are provided on the base 1, which are respectively located on both sides of the driven plate 13, and the first limit plate 14 is provided with a first straight groove 1401 and a first inclined groove 1402 connected and adapted to the first boss 1301, and the first boss 1301 passes through the first straight groove 1401 and is slidably connected to the first limit plate 14.

[0048] Furthermore, the elastic component includes a protruding block 17 installed at the bottom of the base 1 and slidably connected to the connecting plate 9, a plurality of cross bars 18 fixed on the connecting plate 9, and a plurality of cylindrical springs 19 respectively sleeved on the outer peripheries of the plurality of cross bars 18, and the cross bars 18 pass through the protruding block 17 and are slidably connected thereto, one end of the cylindrical spring 19 is connected to the connecting plate 9, and the other end is connected to the protruding block 17.

[0049] The movable arm group includes a rotating shaft 10 rotatably installed on the side of the base 1, two guide arms 11 fixed on the rotating shaft 10, and two telescopic arms 12 slidably mounted on the two guide arms 11 respectively. The end of the driven plate 13 away from the base 1 is rotatably connected to the two telescopic arms 12.

[0050] It should be emphasized that when the telescopic arm 12 is in a horizontal state, its height is higher than the receiving seat 2. After the pipe is shaped twice, the first hydraulic cylinder 4 drives the fastener 7 to lift up through the assembly plate 6. In the latter part of the lifting stroke of the fastener 7, the driving wheel 8 acts on the inclined surface 901, thereby causing the connecting plate 9 to give way, and the cross bar 18 slides on the protruding block 17. The column spring 19 is compressed. During this process, the connecting plate 9 will cause the lifting mechanism to move, and the lifting mechanism will lift the pipe on the receiving seat 2 to a specific height (higher than the telescopic arm 12). The connecting plate 9 drives the telescopic arm 12 to slide on the guide arm 11 away from the rotating shaft 10 through the driven plate 13. After the first boss 1301 enters the first inclined groove 1402, the telescopic arm 12 reaches between the pipe fitting and the receiving seat 2, and the driven plate 13 moves upward on the connecting plate 9. Then, the driven plate 13 prompts the guide arm 11 and the telescopic arm 12 to swing upward, so that the pipe fitting is separated from the lifting mechanism, and rolls down to the side of the base 1 along the telescopic arm 12 and the guide arm 11 which are in an inclined state at this time, and finally rolls onto the conveyor belt arranged on the side of the base 1.

[0051] The lifting mechanism includes a lifting plate 15 which is slidably connected to the base 1 and the receiving seat 2, and a second convex column 1501 is respectively provided on both sides of the lifting plate 15, and a second limiting plate 16 is respectively installed on both sides of the connecting plate 9, and the second limiting plate 16 is provided with a connected second inclined groove 1601 and a second straight groove 1602, and the second convex column 1501 passes through the second inclined groove 1601 and is slidably connected to the second limiting plate 16.

[0052] The driving wheel 8 moves upward and acts on the inclined surface 901, causing the connecting plate 9 to give way. First, synchronously, the first convex column 1301 moves in the first straight groove 1401, and the second convex column 1501 moves in the second inclined groove 1601. As a result, the guide arm 11 and the telescopic arm 12 do not deflect, and under the action of the second inclined groove 1601, the ejection plate 15 moves upward to lift the pipe upward. After the second convex column 1501 is flush with the second straight groove 1602, the ejection plate 15 maintains the current height and the pipe remains stationary on the ejection plate 15. Then, the first convex column 1301 moves into the first inclined groove 1402, causing the guide arm 11 and the telescopic arm 12 to deflect upward, so that the pipe on the ejection plate 15 rolls along the telescopic arm 12 and the guide arm 11 to the side of the base 1 onto the conveyor belt.

[0053] Please refer again Figure 1 , Figure 5 as well as Figure 8 The hydraulic pushing mechanism includes two second hydraulic cylinders 5 mounted on the base 1 and a transverse plate 20 fixedly mounted on the movable ends of the two second hydraulic cylinders 5. The transverse plate 20 is provided with a guide groove, and a movable block 23 is slidably engaged in the guide groove. The movable block 23 is connected to the shifting mechanism. The first plastic member 21 and the second plastic member 22 are mounted on the side of the movable block 23 facing the receiving seat 2. A mounting frame 27 is provided on the transverse plate 20. The shifting mechanism includes a vertical shaft 24 rotatably mounted on the mounting frame 27 and two groups of elastic telescopic rods 25 fixed to the vertical shaft 24. One end of the two groups of elastic telescopic rods 25 is rotatably connected to the movable block 23, and the other end is fixedly connected to a transmission plate 26. The transmission plate 26 cooperates with a trigger structure provided on the mounting frame 27.

[0054] The trigger structure includes a sliding seat 28 slidably mounted on the mounting frame 27 and two driving rollers 29 rotatably mounted at the bottom of the sliding seat 28. A cam 31 is also rotatably mounted on the mounting frame 27, and a third convex column 3101 is arranged on the cam 31. A strip plate 30 is arranged on the upper part of the sliding seat 28, and a groove matching the third convex column 3101 is arranged on the strip plate 30. The third convex column 3101 extends into the groove and is slidably connected to the strip plate 30. A ratchet 32 ​​is also arranged on the rotating shaft of the cam 31, and the ratchet 32 ​​cooperates with a ratchet plate 33 mounted on the base 1.

[0055] Whenever the second hydraulic cylinder 5 drives the transverse plate 20 to drive the movable block 23 and the two shaping parts to move toward the pipe fitting, before the shaping part and the pipe fitting are about to contact, the ratchet 32 ​​is disengaged from the pawl on the ratchet plate 33. During this process, the ratchet 32 ​​does not rotate. When the second hydraulic cylinder 5 drives the transverse plate 20 to retract and reset, after the shaping part and the pipe fitting are disengaged, the ratchet 32 ​​will contact the pawl on the ratchet plate 33 again and rotate. Then, when the transverse plate 20 is reset, the ratchet 32 ​​and the cam 31 have completed a half-circle rotation. Accordingly, the third boss 3101 is slidably matched with the strip plate 30. , so that the sliding seat 28 drives the two driving rollers 29 to move. At this time, one of the driving rollers 29 causes the elastic telescopic rod 25 to deflect through the transmission plate 26, and the elastic telescopic rod 25 drives the movable block 23 to slide in the guide groove of the transverse plate 20. During the deflection of the elastic telescopic rod 25 in the first half, the compression amount of the spring inside it gradually increases. After entering the second half of the deflection, the spring inside it will rebound, so that the movable block 23 automatically completes the sliding of the second half, and under the action of the internal spring, the movable block 23 is tightly against the inner wall of the guide groove to ensure the accurate position replacement of the first plastic member 21 and the second plastic member 22.

[0056] As another embodiment of the present invention, a port shaping method for automobile pipe fittings is also proposed, using the above-mentioned shaping production equipment, comprising the following steps:

[0057] Step 1: transport the pipe to the receiving seat 2, and press the fastening mechanism downward to fix the pipe;

[0058] Step 2: The hydraulic pushing mechanism performs a first reciprocating motion, so that the first shaping member 21 acts on the end of the pipe fitting to complete a shaping operation, and the transposition mechanism drives the first shaping member 21 and the second shaping member 22 to move and transpose;

[0059] Step 3: The hydraulic pushing mechanism performs a second reciprocating motion, so that the second shaping member 22 acts on the end of the pipe fitting to complete the secondary shaping, and the transposition mechanism drives the first shaping member 21 and the second shaping member 22 to move and reset;

[0060] Step 4: the fastening mechanism is lifted up, prompting the lifting mechanism to lift the pipe on the receiving seat 2, and the pipe transfer mechanism is translated to the bottom of the pipe and then performs a swinging action to transfer the pipe in a rolling manner.

[0061] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
