Description

Technical Field

[0001] The invention relates to the technical field of jack manufacturing, in particular to a quick press-fit device for a wire retaining ring. Background Art

[0002] A jack is usually assembled from a base, a sealing steel ball, a steel ball retaining ring, a piston rod, a pump core, a wire retaining ring and an oil plug. After the piston rod is installed into the base, the wire retaining ring needs to be inserted into the preset groove on the inner wall of the base to limit the piston rod inserted into the base to prevent the piston rod from falling off from the base. Currently, the wire retaining ring is manually installed into the base, but due to the overall hardness of the wire retaining ring, it is inconvenient for the staff to manually compress the wire retaining ring, which makes the installation extremely difficult. In addition, since the wire retaining ring is difficult to grip, it may injure the operator or the product if it loses control during installation.

[0003] Therefore, in order to improve the installation efficiency of the jack, existing factories usually use a vibration plate to load the wire retaining ring, and then use a material distribution robot to transport the wire retaining ring to the installation robot for installation, without the need for manual loading and installation of the wire retaining ring. Although this method saves labor, the equipment investment cost and maintenance cost are high. Therefore, a wire retaining ring quick pressing device is also needed to improve the installation efficiency of the wire retaining ring while saving equipment investment.

[0004] After searching, the patent document with Chinese patent application number CN202310030137.0 discloses an installation tool for a piston wire retaining ring and a method of using the same, including a positioning support assembly, a sliding support assembly, a downward pressure drive assembly, a driven assembly, a material storage assembly and a material pushing assembly. However, the above technical solution still requires staff to manually load the wire retaining ring, and manually press the handle to install the wire retaining ring into the corresponding workpiece.

[0019] In a further solution, the inner wall of the material guiding cover is rotatably connected to a plurality of pulleys.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention can automatically load the wire retaining ring body, and at the same time adjust the notch of the wire retaining ring body to align with one side of the mounting plate through the notch calibration mechanism, so that when the wire retaining ring body is pushed downward, the notch on one side of the wire retaining ring body can pass through the mounting plate, thereby avoiding the collision between the wire retaining ring body and the connecting part of the mounting plate and the mounting sleeve when the wire retaining ring body moves. At the same time, only one electric hydraulic push rod is used to drive the pushing and extruding mechanism to move downward and upward back and forth, so as to complete the positioning, pushing and installation of the wire retaining ring body, and the wire retaining ring body can be installed in the jack base continuously, thereby reducing the equipment investment and improving the jack installation efficiency.

[0022] 2. The arc-shaped metal spring sheet of the present invention will stretch to both sides under the extrusion of the support plate, driving the material guide covers connected on both sides of the arc-shaped metal spring sheet to move to both sides, releasing the support of the material guide covers for the wire retaining ring body, and moving the wire retaining ring body to the top of the installation sleeve to complete the positioning and transportation of the wire retaining ring body. As the mounting frame continues to move downward, the pressure block will now rest against the other side of the arc-shaped metal spring sheet. At this time, the mounting frame will squeeze the support plate through the pressure block, and the thrust provided by the electric hydraulic push rod will compress the compression spring at the bottom of the support plate, pushing the extrusion rod and the extrusion sheet at the bottom of the support plate to push the wire retaining ring body moved between the piston rod and the inner wall of the jack base into the limit groove on the inner wall of the jack base, thereby completing the installation of the wire retaining ring body.

[0023] 3. The present invention drives the pushing fan blades to rotate clockwise through a motor, and pushes the wire retaining ring body on the conveying plate to move downward into the material guide cover through the blades of the pushing fan blades. When the notch of the wire retaining ring body is not in a position directly facing the rotating rubber wheel, the outer wall of the wire retaining ring body will be pushed against the side of the rotating rubber wheel by the pushing of the pushing fan blades. At this time, the wire retaining ring body will be driven by the friction between the rubber wheel and the rubber wheel to rotate under the limit of the material guide cover and the pushing fan blades. When the notch of the wire retaining ring body rotates to the side of the rubber wheel, the wire retaining ring body will continue to move forward under the push of the pushing fan blades, and enter the inner wall of the material guide cover as a whole, thereby completing the notch positioning and transportation of the wire retaining ring body.

[0024] 4. In the present invention, when the electric hydraulic push rod drives the mounting frame to move upward and reset, the arc-shaped metal spring piece will be retracted and reset inward under the action of its own elastic force and the elastic force of the elastic telescopic rod, thereby pulling the sliding frame and the material guide cover on both sides to reset and receive the next wire retaining ring body conveyed by the conveying plate.

[0025] 5. In the present invention, when the guide sleeve moves inwardly driven by the material guide cover, it will push the telescopic end of the cylinder to contract, thereby reducing the speed at which the guide sleeve and the material guide cover are retracted inwardly. After the arc-shaped push plate follows the mounting frame to rise to a height higher than the top of the mounting sleeve, the guide sleeve will move inwardly to the initial position under the support of the cylinder, allowing the arc-shaped push plate to directly rest against one side of the inclined plate again under the elastic force of the elastic push rod, ready to continue to push the next wire retaining ring body.

DETAILED DESCRIPTION

[0039] 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.

[0040] The present invention provides a technical solution:

[0041] Embodiment 1:

[0042] like Figure 1-11 As shown, a wire retaining ring quick pressing device comprises a support platform 1 and a conveyor belt 2, the conveyor belt 2 is arranged on one side of the support platform 1, and a vibration plate loader 9 and a conveying plate 8 are arranged on the top outer wall of the support platform 1, the vibration plate loader 9 loads the wire retaining ring body 12, and sequentially conveys and transfers it through the conveying plate 8, an electric hydraulic push rod 7 is fixed to the top outer wall of the support platform 1 through a bracket, a mounting frame 6 is fixed to the output shaft of the electric hydraulic push rod 7, a support plate 29 is fixed to the outer wall of the mounting frame 6, a guide sleeve 22 is slidably connected to the outer wall of the support plate 29, a material guide cover 25 is fixed to the outer wall of the guide sleeve 22, a sliding frame 28 is fixed to the outer wall of one side of the material guide cover 25, a sliding frame 28 is fixed to the outer wall of the bottom of the sliding frame 28, an elastic push rod 17 is rotatably connected to the outer wall of the bottom of the elastic push rod 17, an arc-shaped push plate 40 is fixed to the outer wall of the bottom of the elastic push rod 17, an outer wall of one side of the elastic push rod 17 is connected to the outer wall of one side of the material guide cover 25 through a tension spring, the inner wall of the sliding frame 28 is rotatably connected to the pushing and extruding mechanism, and a notch calibration mechanism is arranged on the outer wall of one side of the support plate 29;

[0043] The pushing and squeezing mechanism positions, pushes and installs the wire retaining ring body 12 , and the notch calibration mechanism adjusts the notch of the wire retaining ring body 12 .

[0044] A plurality of jack bases 3 are arranged and placed on the conveyor belt 2, a piston rod 5 is inserted into the inner wall of the jack base 3, a limiting slot 39 is opened on the inner wall of the jack base 3, a mounting plate 4 is fixed to the outer wall of the conveyor belt 2, a mounting sleeve 14 is fixed to the outer wall of one side of the mounting plate 4 through a fixing rod, a compression spring 32 is fixed to the inner wall of the mounting sleeve 14, a support plate 20 is fixed to the outer wall of the compression spring 32, a plurality of trapezoidal guide blocks 33 are fixed to the outer wall of the mounting sleeve 14, a group of extrusion rods 34 are fixed to the outer wall of the bottom of the support plate 20, a group of limiting slots 37 are opened on the inner wall of the mounting sleeve 14, the extrusion rod 34 is slidably connected to the inner wall of the limiting slot 37, an extrusion sheet 35 is fixed to the outer wall of the bottom of the extrusion rod 34, and an inclined plate 38 is fixed to the outer wall of the extrusion rod 34 and the support plate 20.

[0045] During the press-fitting operation, the staff puts the wire retaining ring body 12 to be installed into the vibrating plate feeder 9. At the same time, the jack base 3 on which the piston rod 5 has been installed in the previous process moves to the bottom of the mounting frame 6 under the conveyance of the conveyor belt 2. Then the main controller controls the conveyor belt 2 to stop moving. At this time, the wire retaining ring body 12 inside the vibrating plate feeder 9 enters the conveying plate 8 in turn, and enters between the two material guide covers 25 under the conveyance of the conveying plate 8. Then, the notch of the wire retaining ring body 12 is adjusted to align with the side of the mounting plate 4 under the adjustment of the notch calibration mechanism on one side of the support plate 29, and then the electric hydraulic push rod 7 pushes The movable mounting frame 6 moves downward as a whole. When the mounting frame 6 moves downward, it drives the wire retaining ring body 12 supported by the inner wall of the material guide cover 25 to move downward, and the wire retaining ring body 12 is sleeved on the outside of the compression spring 32 and the extrusion rod 34. As the mounting frame 6 continues to move downward, the support plate 20 located on the top of the compression spring 32 will squeeze the pushing and squeezing mechanism, thereby pushing the material guide covers 25 on both sides to move to both sides respectively, thereby releasing the support of the material guide cover 25 on the wire retaining ring body 12, allowing the wire retaining ring body 12 to fall to the top of the trapezoidal guide block 33 outside the mounting sleeve 14, and sleeved on the outer wall of the inclined plate 38;

[0046] When the mounting frame 6 moves downward, the sliding frame 28 and the elastic push rod 17 connected by the tension spring at the bottom of the material guide cover 25 will be driven to move downward. When the elastic push rod 17 moves downward, it will push the arc push plate 40 to move downward under the guidance and support of the inclined plate 38, so that the arc push plate 40 at the bottom of the elastic push rod 17 pushes the wire retaining ring body 12 that is previously sleeved on the outer wall of the trapezoidal guide block 33 through the above steps to move downward. As the arc push plate 40 continuously pushes the wire retaining ring body 12 to move downward, the wire retaining ring body 12 will open under the guidance of the trapezoidal guide block 33 through its own elastic force. After the body 12 moves to the inclined surface at the bottom of the trapezoidal guide block 33, it will retract by its own elastic force and then fall into the gap between the piston rod 5 and the jack base 3. At this time, the pushing and squeezing mechanism just moves to the top of the support plate 20. As the pushing and squeezing mechanism continues to move downward under the push of the mounting frame 6, the sliding frame 28 will also move to both sides with the elastic pushing rod 17 at the bottom, so that the elastic pushing rod 17 and the arc-shaped pushing plate 40 that push the wire retaining ring body 12 from the outer wall of the mounting sleeve 14 are away from the outer wall of the mounting sleeve 14, so as to avoid the arc-shaped pushing plate 40 that continues to move downward from colliding with the jack base 3 at the bottom;

[0047] As the pushing and squeezing mechanism continues to squeeze the support plate 20, when the pressure given to the support plate 20 by the pushing and squeezing mechanism exceeds the stiffness coefficient of the compression spring 32, the support plate 20 will move downward under the push of the electric hydraulic push rod 7, thereby pushing the squeezing rod 34 to move downward. When the squeezing rod 34 moves downward, it will push the squeezing sheet 35 at the bottom to move the wire retaining ring body 12 that has previously fallen between the piston rod 5 and the inner wall of the jack base 3 through the above steps downward. When the squeezing sheet 35 pushes the wire retaining ring body 12 to one side of the limiting card slot 39, the wire retaining ring body 12 will be elastically stuck on the inner wall of the limiting card slot 39, thereby inserting The piston rod 5 inside the jack base 3 is limited, and the electric hydraulic push rod 7 will also drive the mounting frame 6 to move upward and reset as a whole. At this time, the support plate 20 will also be reset under the push of the compression spring 32. At the same time, the elastic push rod 17 will also be reset under the drive of the tension spring, and follow the pushing and squeezing mechanism to be recovered inward and rest against the outer wall of the inclined plate 38 again. As the mounting frame 6 continues to rise, the pushing and squeezing mechanism will be reset by its own elastic force after no longer being squeezed by the support plate 20, thereby receiving the next wire retaining ring body 12 delivered by the conveying plate 8, and then repeating the above steps to install the next wire retaining ring body 12.

[0048] The present invention can automatically load the wire retaining ring body 12, and at the same time adjust the notch of the wire retaining ring body 12 to align with one side of the mounting plate 4 through the notch calibration mechanism, so that when the wire retaining ring body 12 is pushed downward, the notch on one side of the wire retaining ring body 12 can pass through the mounting plate 4, thereby avoiding the wire retaining ring body 12 from colliding with the connecting portion of the mounting plate 4 and the mounting sleeve 14 when moving. At the same time, only one electric hydraulic push rod 7 is used to drive the pushing and extruding mechanism to move downward and upward back and forth, so as to complete the positioning, pushing and installation of the wire retaining ring body 12, and the wire retaining ring body 12 can be continuously installed in the jack base 3, thereby reducing the equipment investment and improving the jack installation efficiency.

[0049] like Figure 2-3 As shown, the pushing and squeezing mechanism includes a pressing block 26, an elastic telescopic rod 24, a pushing frame 27 and an arc-shaped metal spring 10, the pressing block 26 is fixed on the top inner wall of the mounting frame 6, the elastic telescopic rod 24 is respectively fixed on the outer walls on both sides of the pressing block 26, the pushing frame 27 is fixed on the telescopic end of the elastic telescopic rod 24, the arc-shaped metal spring 10 is fixed on the outer wall of one side of the pushing frame 27, and the pushing frame 27 is rotatably connected to the inner wall of the sliding frame 28; the sum of the stiffness coefficients of the arc-shaped metal spring 10 and the elastic telescopic rod 24 is less than the stiffness coefficient of the compression spring 32;

[0050] When the electric hydraulic push rod 7 pushes the mounting frame 6 to move downward, it will drive the arc-shaped metal spring piece 10 to move downward. When the arc-shaped metal spring piece 10 moves to the top of the support plate 20, it will stretch to both sides under the pressure of the support plate 20, thereby driving the guide cover 25 connected on both sides of the arc-shaped metal spring piece 10 to move to both sides, thereby releasing the support of the guide cover 25 on the wire retaining ring body 12, and moving the wire retaining ring body 12 to the top of the installation sleeve 14, completing the positioning and transportation of the wire retaining ring body 12. As the mounting frame 6 continues to move downward, when the support plate 20 of the arc-shaped metal spring piece 10 is squeezed, the wire retaining ring body 12 is moved to the top of the installation sleeve 14, and the positioning and transportation of the wire retaining ring body 12 are completed. After being pressed down and extended to the maximum length, the pressing block 26 located on the inner wall of the mounting frame 6 will now abut against the other side of the arc-shaped metal spring sheet 10. At this time, the mounting frame 6 that is continuously moving downward will squeeze the support plate 20 through the pressing block 26, thereby pushing the compression spring 32 at the bottom of the support plate 20 to be compressed through the thrust provided by the electric hydraulic push rod 7, thereby pushing the extrusion rod 34 and the extrusion sheet 35 at the bottom of the support plate 20 to push the wire retaining ring body 12 that moves between the piston rod 5 and the inner wall of the jack base 3 into the limit slot 39 on the inner wall of the jack base 3, thereby completing the installation of the wire retaining ring body 12;

[0051] When the electric hydraulic push rod 7 drives the mounting frame 6 to move upward and reset, the arc-shaped metal spring sheet 10 will be retracted and reset inward under the action of its own elastic force and the elastic force of the elastic telescopic rod 24, thereby pulling the sliding frame 28 and the material guide cover 25 on both sides to reset and receive the next wire retaining ring body 12 transported by the conveying plate 8.

[0052] like Figure 2 , Figure 3 and Fig.10As shown, the notch calibration mechanism includes a pusher blade 11, a motor 18, a connecting plate 23 and a rubber wheel 21. The motor 18 is fixed to an outer wall of one side of the conveying plate 8, and the output shaft of the motor 18 passes through an outer wall of one side of the conveying plate 8. The pusher blade 11 is fixed to the output shaft of the motor 18, and the connecting plate 23 is fixed to an outer wall of one side of the support plate 29. The rubber wheel 21 is rotatably connected to the inner wall of the connecting plate 23. The inner wall of the connecting plate 23 is provided with a motor, and the output shaft of the motor is connected to the rubber wheel 21 through a transmission chain; the motor 18 drives the pusher blade 11 to rotate clockwise, thereby pushing the wire retaining ring body 1 on the conveying plate 8 through the blades of the pusher blade 11 2 moves downward into the material guide cover 25. When the notch of the wire retaining ring body 12 is not in the position facing the rotating rubber wheel 21, the outer wall of the wire retaining ring body 12 will be pushed by the material pushing blade 11 to abut against the side of the rotating rubber wheel 21. At this time, the wire retaining ring body 12 will rotate under the limit of the material guide cover 25 and the material pushing blade 11 driven by the friction between the wire retaining ring body 12 and the rubber wheel 21. When the notch of the wire retaining ring body 12 rotates to the side of the rubber wheel 21, the wire retaining ring body 12 will continue to move forward under the push of the material pushing blade 11 and enter the inner wall of the material guide cover 25 as a whole, thereby completing the notch positioning and transportation of the wire retaining ring body 12.

[0053] like Figure 7 As shown, the inner wall of the material guide cover 25 is rotatably connected with a plurality of pulleys 36 ; the pulleys 36 can support the wire retaining ring body 12 inside the material guide cover 25 while improving the stability of the wire retaining ring body 12 as a whole when rotating inside the material guide cover 25 .

[0054] like Figure 2 , Figure 6 , Figure 7 and Fig. 9As shown, the outer wall of the support plate 29 is fixed with a limiting sleeve 31, the inner wall of the limiting sleeve 31 is slidably connected with a guide rod 16, the outer wall of the top of the guide rod 16 is fixed with a limiting ring 30, the guide rod 16 passes through the outer wall of one side of the mounting plate 4, and the outer wall of one side of the guide rod 16 is fixed with a guide cover 19; when the electric hydraulic push rod 7 pushes the mounting frame 6 to move downward, it will drive the guide rod 16 slidably connected to the inner wall of the limiting sleeve 31 to move downward, so that the guide cover 19 at the bottom of the guide rod 16 can move to the top of the jack base 3, and when the guide cover 19 moves to the top of the jack base 3, the mounting frame 6 will still be It moves downward under the push of the electric hydraulic push rod 7. At this time, the guide rod 16 will slide on the inner wall of the limit sleeve 31 under the support of the guide cover 19. At this time, the wire retaining ring body 12 pushed down from the mounting sleeve 14 by the arc-shaped push plate 40 will first fall into the guide cover 19, and then fall into the jack base 3 under the guidance of the guide cover 19. The guide cover 19 can limit and guide the wire retaining ring body 12 that falls from the outer wall of the mounting sleeve 14, so that the fallen wire retaining ring body 12 can slide smoothly to the gap between the jack base 3 and the piston rod 5 under the guidance of the guide cover 19.

[0055] like Figure 8 , Fig. 9 As shown, the outer wall of the arc-shaped push plate 40 is fixed with an inclined piece 15, and the outer wall of the guide cover 19 is rotatably connected with a group of guide wheels 13; when the mounting frame 6 drives the elastic push rod 17 to continuously move downward, and at the same time the material guide cover 25 drives the elastic push rod 17 to continuously move to both sides, the inclined piece 15 located on one side of the arc-shaped push plate 40 will collide with the guide wheels 13 on both sides of the guide cover 19, so that under the push of the guide wheels 13, the arc-shaped push plate 40 can quickly move away from one side of the guide cover 19, avoiding the arc-shaped push plate 40 from colliding with the top of the guide cover 19 when moving downward.

[0056] When the present embodiment is in use, the staff puts the wire retaining ring body 12 to be installed into the vibrating plate feeder 9, and at the same time, the jack base 3 on which the piston rod 5 has been installed in the previous process moves to the bottom of the mounting frame 6 under the conveyance of the conveyor belt 2, and then the main controller controls the conveyor belt 2 to stop moving. At this time, the wire retaining ring body 12 inside the vibrating plate feeder 9 enters the guide cover 25 under the conveyance of the conveyor plate 8, and then the notch of the wire retaining ring body 12 is adjusted to align with one side of the mounting plate 4 under the adjustment of the notch calibration mechanism on one side of the support plate 29, and then the electric hydraulic push rod 7 pushes the installation The frame 6 moves downward as a whole. When the mounting frame 6 moves downward, it will drive the wire retaining ring body 12 supported by the inner wall of the material guide cover 25 to move downward, and the wire retaining ring body 12 will be sleeved on the outside of the compression spring 32 and the extrusion rod 34. As the mounting frame 6 continues to move downward, the support plate 20 located on the top of the compression spring 32 will squeeze the pushing and squeezing mechanism, pushing the material guide covers 25 on both sides to move to both sides respectively, releasing the support of the material guide cover 25 on the wire retaining ring body 12, allowing the wire retaining ring body 12 to fall to the top of the trapezoidal guide block 33 outside the mounting sleeve 14, and sleeved on the outer wall of the inclined plate 38;

[0057] When the mounting frame 6 moves downward, the sliding frame 28 and the elastic push rod 17 connected by the tension spring at the bottom of the guide cover 25 will be driven to move downward. When the elastic push rod 17 moves downward, it will push the arc push plate 40 to move downward under the guidance and support of the inclined plate 38. The arc push plate 40 at the bottom of the elastic push rod 17 pushes the wire retaining ring body 12 that is previously sleeved on the outer wall of the trapezoidal guide block 33 through the above steps to move downward. As the arc push plate 40 continuously pushes the wire retaining ring body 12 to move downward, the wire retaining ring body 12 will be moved on the trapezoidal guide block by its own elastic force. 33, when the wire retaining ring body 12 moves to the inclined surface at the bottom of the trapezoidal guide block 33, it will retract by its own elastic force and then fall into the gap between the piston rod 5 and the jack base 3. At this time, the pushing and squeezing mechanism just moves to the top of the support plate 20. As the pushing and squeezing mechanism continues to move downward under the push of the mounting frame 6, the sliding frame 28 will also move to both sides with the elastic pushing rod 17 at the bottom, so that the elastic pushing rod 17 and the arc-shaped pushing plate 40 that push the wire retaining ring body 12 down from the outer wall of the mounting sleeve 14 are away from the outer wall of the mounting sleeve 14.

[0058] As the pushing and squeezing mechanism continues to squeeze the support plate 20, when the pressure given to the support plate 20 by the pushing and squeezing mechanism exceeds the stiffness coefficient of the compression spring 32, the support plate 20 will move downward under the push of the electric hydraulic push rod 7, pushing the squeezing rod 34 to move downward. When the squeezing rod 34 moves downward, it will push the squeezing sheet 35 at the bottom to move the wire retaining ring body 12 that has previously fallen between the piston rod 5 and the inner wall of the jack base 3 through the above steps downward. When the squeezing sheet 35 pushes the wire retaining ring body 12 to one side of the limiting groove 39, the wire retaining ring body 12 will be elastically stuck on the inner wall of the limiting groove 39 to limit the piston rod 5 inserted into the jack base 3. At this time, the electric hydraulic push rod 7 will also drive the mounting frame 6 to move upward as a whole and reset. Then repeat the above steps to install the next wire retaining ring body 12.

[0059] Embodiment 2:

[0060] A quick press-fit device for a wire retaining ring, such as Fig.10 As shown, the present embodiment makes the following improvements on the basis of the embodiment 1: a group of cylinders 41 are fixed to the outer wall of the support plate 29, and the telescopic end of the cylinder 41 is fixed to the outer wall of one side of the guide sleeve 22; when the electric hydraulic push rod 7 drives the mounting frame 6 to move upward and reset, the guide cover 25 will move back quickly under the elastic force of the arc-shaped metal spring sheet 10 and the elastic telescopic rod 24, in order to prevent the guide cover 25 from driving the elastic push rod 17 and the arc-shaped push plate 40 to move to the outer wall of the mounting sleeve 14 too quickly, resulting in the arc-shaped push plate 40 following the elastic push rod 17 to move upward and the wire retaining ring body 1 just placed on the top of the mounting sleeve 14. 2, a cylinder 41 is arranged between the support plate 29 and the guide sleeve 22. When the guide sleeve 22 moves inwardly driven by the guide cover 25, the telescopic end of the cylinder 41 is pushed to contract, thereby reducing the speed of the guide sleeve 22 and the guide cover 25 when they are retracted inwardly. After the arc-shaped push plate 40 follows the mounting frame 6 to rise to a height higher than the top of the mounting sleeve 14, the guide sleeve 22 will move inwardly to the initial position under the support of the cylinder 41, so that the arc-shaped push plate 40 can directly press against the side of the inclined plate 38 again under the elastic force of the elastic push rod 17, and prepare to continue to push the next wire retaining ring body 12.

[0061] When this embodiment is in use, when the guide sleeve 22 moves inwardly driven by the material guide cover 25, it will push the telescopic end of the cylinder 41 to contract, thereby reducing the speed at which the guide sleeve 22 and the material guide cover 25 are retracted inwardly. After the arc-shaped push plate 40 follows the mounting frame 6 to rise to a height higher than the top of the mounting sleeve 14, the guide sleeve 22 will move inwardly to the initial position under the support of the cylinder 41.
