Description

Technical Field

[0001] This application belongs to the technical field of shock absorber piston production equipment, and particularly relates to a processing device and method for rubber-coated pressing sheets for automotive shock absorber pistons. Background Technology

[0002] In the suspension system, the elastic elements vibrate due to impact. To improve the smoothness and comfort of the car ride, shock absorbers are installed in parallel with the elastic elements in the suspension. When the frame and axle vibrate and relative movement occurs, the piston in the shock absorber moves up and down. Due to the frequent relative movement between the piston and the shock absorber cylinder, the surface of the piston needs to be coated with a wear-resistant material with low frictional resistance, such as polytetrafluoroethylene, to extend its service life.

[0003] Existing methods for rubber coating pistons mainly include: manually placing the rubber-coated sheet on the piston, using a manual pressing mechanism to fit the sheet onto the piston, and heating the die to achieve the coating effect. However, this method has low production efficiency and produces inconsistent quality finished products.

[0004] Patent CN109080126B discloses a piston overmolding and pressing thermoforming apparatus, including a feeding module mounted on a substrate for transporting pre-overmolded pistons, and a clamping and conveying module for feeding the pre-overmolded pistons to a pressing module. The pressing module includes a press support mounted on the substrate, a forming mold assembly mounted on the press support, and a pressing device for pressing the pre-overmolded pistons into the forming mold assembly. The forming mold assembly includes a cooling mold shell mounted on the press support, with a hollow heating section at the upper end of the cooling mold shell and a hollow cooling section coaxial with the heating section inside the cooling mold shell. A mold shell sleeve is sealed to the outside of the cooling mold shell, forming a cooling chamber between the cooling mold shell and the mold shell sleeve. Multiple fins extending into the cooling chamber are provided on the side of the cooling mold shell.

[0005] The aforementioned patent completes the thermoforming of the rubber-coated piston through the coordinated use of a clamping and conveying module, a booster cylinder, a pressing head, a pressing device, and a cooling mold shell. However, there are still many problems in the processing. The rubber-coated piston of the aforementioned patent is fed into the heating section by a booster cylinder and a pressing device. During the pushing process, it relies solely on guide pillars and linear bearings for pushing stability. The stabilization effect is insufficient, and there is no corresponding buffer function, which can easily lead to pushing errors and cause unnecessary losses. Summary of the Invention

[0006] The purpose of this application is to provide a processing apparatus and method for rubber-coated pressing sheets for automotive shock absorber pistons, which can solve the above-mentioned problems.

[0007] The purpose of this application is to provide a processing apparatus for rubber-coated pressing sheets for automotive shock absorber pistons, including a frame and a pushing device disposed on one side of the frame, comprising:

[0008] A forming device, mounted on a frame, is used for thermoforming overmolded sheets.

[0009] A conveying device, mounted on a frame and located above the forming device, is used to convey the overmolded sheet into the forming device;

[0010] The pushing device pushes the overmolded sheet between the molding device and the conveying device, and the conveying device presses the overmolded sheet into the molding device.

[0011] The aforementioned processing device for rubber-coated sheet for automotive shock absorber pistons incorporates a pushing device consisting of a conveyor belt and grippers. The conveyor belt transports the rubber-coated sheet to the side of the frame, while the grippers pick up the sheet and transport it to the forming device. The conveying device then transports the sheet into the forming device, where it processes the sheet by heating and then cooling it. Furthermore, the conveying device ensures stable transport of the rubber-coated sheet during the process of transporting it to the forming device.

[0012] Furthermore, the molding device includes a heating tube and a cooling tube connected vertically. The outer wall of the heating tube is provided with a heating wire, and the outer wall of the cooling tube is provided with multiple heat dissipation fins. The heating tube and the cooling tube are respectively provided with a first channel and a second channel for the overmolding sheet to pass through.

[0013] The cooling pipe and the heating pipe are interconnected, with the heating pipe located above the cooling pipe. A partition is provided between the two. During use, the heating pipe is heated evenly by an electric heating wire. The rubber-coated sheet enters through the opening of the heating pipe, passes through the first channel, and then enters the second channel. It is heated in the first channel and cooled in the second channel, thus completing the thermoforming of the rubber-coated sheet. During the forming process, the rubber-coated sheet is kept in one end of the first and second channels for a period of time due to the influence of the length of the first and second channels and the driving frequency of the conveying device. This ensures the heating and cooling time and improves the processing quality.

[0014] Furthermore: the conveying device includes:

[0015] Support platform, mounted on the frame;

[0016] A cylinder is mounted on a support platform, and the output shaft of the cylinder passes through the support platform and extends toward the molding device.

[0017] A push head is mounted on the output shaft of the cylinder, and the push head is adapted to the opening of the first channel;

[0018] A guiding device, which guides the pusher head and prevents it from deviating from its intended path;

[0019] The guide device is mounted on the support platform and connected to the cylinder.

[0020] During the conveying of the rubber-coated tablets, the cylinder on the position support platform is activated. The output shaft of the cylinder pushes out, driving the pusher head to push out as well. The output shaft of the cylinder, the pusher head, and the heating tube are all located on the same circumferential axis. Under the action of the cylinder, the pusher head contacts the rubber-coated tablet and gradually presses the rubber-coated tablet into the heating tube, completing the conveying of the rubber-coated tablets. During the conveying process, the movement of the pusher head is affected by the guiding device, which makes the conveying process of the pusher head more stable, avoids the generation of vibration, and reduces the occurrence of conveying accidents.

[0021] Furthermore, the guiding device includes:

[0022] The guide disc is mounted on the output shaft of the cylinder;

[0023] A support circular plate is mounted on the cylinder output shaft, and a support disc is mounted on the bottom of the support circular plate. The push head is mounted on the bottom of the support disc.

[0024] Linear bearings are mounted on a support platform. Multiple linear bearings are arranged in a ring around the cylinder output shaft.

[0025] A guide cylinder, one end of which is connected to the first disc, and the other end of which passes through a linear bearing and is connected to the second disc;

[0026] A buffer mechanism, which is connected to a support circular plate and is used to buffer the movement of the support circular plate;

[0027] Both the guide disc and the support disc are elastic discs, and the guide disc and the support disc are respectively disposed on both sides of the support platform.

[0028] The support platform consists of a platform body and multiple uprights located at the bottom of the platform body. Guide discs and support discs are located on both sides of the platform body, with the guide discs on top and the support discs on the bottom. The arrangement of the two discs, linear bearings, and guide cylinders provides constraints on the movement of the push head, ensuring the accuracy of the push head's movement and preventing deviation. At the same time, the cooperation between the guide cylinder and the linear bearing can reduce friction. However, if the guide cylinder and the linear bearing are subjected to friction during the cooperation process, it will cause changes in the pushing distance. The arrangement of guide discs and support discs can reduce the impact of accidents caused by friction. The axial deformation of the guide discs and support discs allows the output shaft of the cylinder to move a certain distance, thereby compensating for the impact of friction and ensuring that the push head completely presses the rubber-coated pressing plate into the heating tube.

[0029] Furthermore, the buffer mechanism includes:

[0030] The mounting ring is positioned between the support platform and the support circular plate and is mounted on the support platform;

[0031] A guide ring groove is provided on the mounting ring and is adapted to the support circular plate, allowing the support circular plate to slide along the guide ring groove;

[0032] The limiting slide rail is set on the guide ring groove;

[0033] A limiting slider is set on a limiting slide rail and slides along the limiting slide rail; a connecting block connected to the limiting slider is provided on the supporting circular plate.

[0034] A damper is disposed in the guide ring groove, and the telescopic end of the damper is connected to the limiting slider;

[0035] The limiting slide rail is provided in multiple ways, and the multiple limiting sliders are evenly arranged on the guide ring groove.

[0036] Driven by the cylinder, the support plate slides up and down within the mounting ring along the guide ring groove. During the movement of the support plate, multiple connecting blocks on the support plate drive the limiting slider to move on the limiting slide rail. When the push head moves towards the heating tube, the limiting slider slides down along the limiting slide rail. At this time, the extension end of the damper is stretched, buffering the movement of the push head and ensuring its stability. When the push head moves away from the heating tube, the limiting slider moves up along the limiting slide rail. At this time, the extension end of the damper retracts, buffering the movement of the push head and ensuring the stability of the cylinder retraction, thereby ensuring the stability of the next processing. At the same time, by setting multiple limiting slide rails, the force on the support plate can be more stable, thus making the conveying operation of the push head more stable.

[0037] Furthermore, the buffer mechanism also includes:

[0038] An extension groove is provided on the guide ring groove and communicates with the limiting slide rail. The end of the extension groove connected to the limiting slide rail is provided with a turning radius.

[0039] The steering block is mounted on the limit slide rail and hinged to the limit slider.

[0040] The auxiliary slide rail includes a first section and a second section respectively disposed on the side wall of the limiting slide rail and the extension groove. The first section and the second section are interconnected, and auxiliary components adapted to the auxiliary slide rail are disposed on both sides of the steering block.

[0041] The second segment is arc-shaped.

[0042] By setting an extension groove, located at the end of the limiting slide rail near the heating tube, and by setting a turning radius on the extension groove, the turning block can easily enter the extension groove. When the limiting slider moves to its limit position, it will not enter the extension groove. However, since the turning block is hinged to the limiting slider, the turning block will enter the extension groove, thereby restricting the movement of the limiting slider and preventing it from moving further. At this time, the push head delivers the rubber-coated pressing sheet into the heating tube. Meanwhile, the moving block is constantly affected by the damper during its movement to the extension groove, ensuring the stability of the movement.

[0043] Furthermore, by setting the first segment and the arc-shaped second segment, and by setting auxiliary parts on the steering block, the movement of the steering block can be restricted, so that the steering block can only enter the extended groove. The auxiliary parts can be any components that assist the movement of the steering block. Ball bearings are recommended because they have the advantages of small contact area and low friction.

[0044] Furthermore, it also includes a buffer spring. The limiting slide rail is provided with an inner groove for placing the buffer spring. One end of the buffer spring is connected to the inner groove, and the other end is connected to the steering block.

[0045] The buffer spring can buffer the movement of the limit slider and the steering block, thereby buffering the movement of the support plate and the push head. The buffer spring, together with the damper, can further improve the buffering effect. At the same time, when the steering block moves into the extension groove, the direction of movement of the steering block changes, from axial movement to horizontal movement. With the help of the buffer spring, the axial force can be dispersed to the horizontal direction, thereby improving the buffering effect and making the movement of the push head more stable.

[0046] Furthermore, the present invention also discloses a method for processing rubber-coated pressing sheets for automotive shock absorber pistons, comprising the following steps:

[0047] S1. The overmolded sheet is conveyed to the space between the forming device and the conveying device by the pushing device, and the overmolded sheet is placed at the opening of the heating tube;

[0048] S2. Drive the cylinder to operate, so that the cylinder output axis is output in the direction of the heating tube, and the push head contacts the rubber-coated pressing plate and presses the rubber-coated pressing plate into the cooling tube.

[0049] S3, the drive cylinder operates repeatedly, continuously pressing the rubber-coated sheet into the heating tube.

[0050] The beneficial effects of this application are:

[0051] 1. By setting up a pushing device, which consists of a conveyor belt and grippers, the conveyor belt transports the overmolded sheet to the side of the machine frame, the grippers pick up the overmolded sheet and transport it to the molding device, the conveying device transports the sheet into the molding device, the molding device processes the overmolded sheet by heating and then cooling it. At the same time, the setting of the conveying device can also make the conveying process more stable during the process of conveying the sheet to the molding device, ensuring the conveying stability of the overmolded sheet;

[0052] 2. The arrangement of two discs, linear bearings, and guide cylinders provides constraints on the movement of the push head, ensuring the accuracy of the push head's movement and preventing deviation. At the same time, the cooperation between the guide cylinder and the linear bearing reduces friction, and the arrangement of guide discs and support discs reduces the impact of accidents caused by friction. The axial deformation of the guide discs and support discs allows the output shaft of the cylinder to move a certain distance, thereby compensating for the impact of friction and ensuring that the push head completely presses the rubber-coated pressing plate into the heating tube.

[0053] 3. By setting a buffer spring, the movement of the slider and the steering block can be limited and buffered, thereby buffering the movement of the support plate and the push head. The buffer spring, together with the damper, can further improve the buffering effect. At the same time, when the steering block moves into the extension groove, the direction of movement of the steering block changes, from axial movement to horizontal movement. With the cooperation of the buffer spring, the axial force can be dispersed to the horizontal direction, thereby improving the buffering effect and making the movement of the push head more stable.

[0064] The processing apparatus and method for rubber-coated pressing sheets for automotive shock absorber pistons provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0065] Example 1:

[0066] like Figure 1 , Figure 2 and Figure 5 As shown, this application embodiment provides a processing apparatus for rubber-coated pressing sheets for automotive shock absorber pistons, including a frame 100 and a pushing device 110 disposed on one side of the frame 100, comprising:

[0067] The forming device 200 is mounted on the frame 100 and is used for thermoforming the overmolded sheet.

[0068] The conveying device 300 is mounted on the frame 100 and located above the molding device 200. The conveying device 300 is used to convey the overmolded sheet into the molding device 200.

[0069] The pushing device 110 pushes the rubber-coated sheet between the forming device 200 and the conveying device 300, and the conveying device 300 presses the rubber-coated sheet into the forming device 200.

[0070] In some embodiments of this application, such as Figure 1 As shown, the above-mentioned processing device for rubber-coated sheet for automotive shock absorber pistons includes a pushing device 110, which consists of a conveyor belt and grippers. The conveyor belt transports the rubber-coated sheet to the side of the frame 100, and the grippers pick up the rubber-coated sheet and transport it to the forming device 200. The conveying device 300 then transports the sheet into the forming device 200. The forming device 200 processes the rubber-coated sheet by heating and then cooling it. Furthermore, the conveying device 300 ensures a more stable conveying process during the transport of the sheet to the forming device 200, guaranteeing the stability of the rubber-coated sheet transport.

[0071] Example 2:

[0072] This application provides a processing apparatus for rubber-coated pressing sheets for automotive shock absorber pistons. In addition to the above-mentioned technical features, the processing apparatus for rubber-coated pressing sheets for automotive shock absorber pistons in this application also includes the following technical features.

[0073] like Figure 1 , Figure 5 and Figure 5As shown, the molding device 200 includes a heating tube 210 and a cooling tube 220 connected vertically. The outer wall of the heating tube 210 is provided with a heating wire, and the outer wall of the cooling tube 220 is provided with a plurality of heat sinks. The heating tube 210 and the cooling tube 220 are respectively provided with a first channel 230 and a second channel 240 for the overmolding sheet to pass through.

[0074] In this embodiment, the cooling pipe 220 and the heating pipe 210 are interconnected, with the heating pipe 210 located above the cooling pipe 220. A partition is provided between them to insulate against temperature. During use, the heating pipe 210 is uniformly heated by a heating wire. The overmolded sheet enters through the opening of the heating pipe 210, passes through the first channel 230, and then enters the second channel 240. It is heated in the first channel 230 and cooled in the second channel 240, thereby completing the thermoforming of the overmolded sheet. During the forming process, the overmolded sheet is kept in one end of both the first channel 230 and the second channel 240 for a period of time due to the length of the first channel 230 and the second channel 240 and the driving frequency of the conveying device 300, thus ensuring the heating and cooling time and improving the processing quality.

[0075] Example 3:

[0076] This application provides a processing apparatus for rubber-coated pressing sheets for automotive shock absorber pistons. In addition to the above-mentioned technical features, the processing apparatus for rubber-coated pressing sheets for automotive shock absorber pistons in this application also includes the following technical features.

[0077] like Figure 1 , Figure 2 and Figure 5 As shown, the conveying device 300 includes:

[0078] Support platform 310 is mounted on frame 100;

[0079] Cylinder 320 is mounted on support platform 310, and the output shaft of cylinder 320 passes through support platform 310 and extends toward molding device 200;

[0080] The push head 330 is mounted on the output shaft of the cylinder 320, and the push head 330 is adapted to the opening of the first channel 230;

[0081] The guide device 400 is used to guide the push head 330 and prevent push deviation.

[0082] The guide device 400 is mounted on the support platform 310 and connected to the cylinder 320.

[0083] In this embodiment, during the conveying of the coated sheet, the cylinder 320 on the position support platform 310 is activated. The output shaft of the cylinder 320 pushes out and drives the pusher head 330 to push out as well. The output shaft of the cylinder 320, the pusher head 330, and the heating tube 210 are all located on the same circumferential axis. Under the action of the cylinder 320, the pusher head 330 contacts the coated sheet and gradually presses the coated sheet into the heating tube 210, completing the conveying of the coated sheet. During the conveying process, the movement of the pusher head 330 is affected by the guide device 400, which makes the conveying process of the pusher head 330 more stable, avoids the generation of vibration, and reduces the occurrence of conveying accidents.

[0084] Example 4:

[0085] This application provides a processing apparatus for rubber-coated pressing sheets for automotive shock absorber pistons. In addition to the above-mentioned technical features, the processing apparatus for rubber-coated pressing sheets for automotive shock absorber pistons in this application also includes the following technical features.

[0086] like Figure 1 , Figure 2 , Figure 3 As shown, the guide device 400 includes:

[0087] Guide disc 410 is mounted on the output shaft of cylinder 320;

[0088] A support plate 420 is mounted on the output shaft of the cylinder 320. A support disc 421 is mounted on the bottom of the support plate 420, and a push head 330 is mounted on the bottom of the support disc 421.

[0089] Linear bearings 430 are mounted on the support platform 310. Multiple linear bearings 430 are provided and are arranged in a ring around the output shaft of the cylinder 320.

[0090] Guide cylinder 440, one end of guide cylinder 440 is connected to the first disc, and the other end passes through linear bearing 430 and is connected to the second disc;

[0091] A buffer mechanism 500 is connected to the support circular plate 420 and is used to buffer the movement of the support circular plate 420.

[0092] Both the guide disc 410 and the support disc 421 are elastic discs, and the guide disc 410 and the support disc 421 are respectively disposed on both sides of the support platform 310.

[0093] In this embodiment, the support platform 310 consists of a platform body and multiple uprights disposed at the bottom of the platform body. Guide discs 410 and support discs 421 are located on opposite sides of the platform body, with guide disc 410 positioned above the platform body and support disc 421 positioned below. The arrangement of the two discs, linear bearing 430, and guide cylinder 440 provides constraints on the movement of the push head 330, ensuring the accuracy of the push head 330's movement and preventing offset. Simultaneously, the cooperation between the guide cylinder 440 and the linear bearing 430... To reduce friction, however, once the guide cylinder 440 and the linear bearing 430 are subjected to friction during the engagement process, the pushing distance will change. The setting of the guide disc 410 and the support disc 421 can reduce the impact of accidents caused by friction. The axial deformation of the guide disc 410 and the support disc 421 allows the output shaft of the cylinder 320 to be displaced by a certain distance, thereby compensating for the impact of friction and ensuring that the pushing head 330 completely presses the rubber-coated pressing sheet into the heating tube 210.

[0094] Example 5:

[0095] This application provides a processing apparatus for rubber-coated pressing sheets for automotive shock absorber pistons. In addition to the above-mentioned technical features, the processing apparatus for rubber-coated pressing sheets for automotive shock absorber pistons in this application also includes the following technical features.

[0096] like Figure 2 , Figure 3 , Figures 4 to 7 As shown, the buffer mechanism 500 includes:

[0097] The mounting ring 510 is disposed between the support platform 310 and the support circular plate 420 and is mounted on the support platform 310;

[0098] A guide ring groove 520 is provided on the mounting ring 510 and is adapted to the support circular plate 420, and the support circular plate 420 can slide along the guide ring groove 520;

[0099] The limiting slide rail 530 is set on the guide ring groove 520;

[0100] The limiting slider 540 is set on the limiting slide rail 530 and slides along the limiting slide rail 530. The supporting circular plate 420 is provided with a connecting block 541 that is connected to the limiting slider 540.

[0101] The damper 550 is disposed in the guide ring groove 520, and the telescopic end of the damper 550 is connected to the limit slider 540.

[0102] The limiting slide rail 530 is provided with multiple limiting slides 540, which are evenly arranged on the guide ring groove 520.

[0103] In this embodiment, driven by the cylinder 320, the support plate 420 slides up and down within the mounting ring 510 along the guide ring groove 520. During the movement of the support plate 420, multiple connecting blocks 541 located on the support plate 420 drive the limiting slider 540 to move on the limiting slide rail 530. When the push head 330 moves towards the heating tube 210, the limiting slider 540 slides down along the limiting slider 540. At this time, the telescopic end of the damper 550 is stretched, which affects the movement of the push head 330. The movement of the push head 330 is buffered to ensure stable movement. When the push head 330 moves away from the heating tube 210, the limit slider 540 moves upward along the limit slide rail 530. At this time, the extension end of the damper 550 retracts to buffer the movement of the push head 330, ensuring the stability of the cylinder 320 retraction, and thus ensuring the stability of the next processing. At the same time, by setting multiple limit slide rails 530, the force on the support plate 420 can be made more stable, thus making the conveying operation of the push head 330 more stable.

[0104] Furthermore, the buffer mechanism 500 also includes:

[0105] An extension groove 560 is provided on the guide ring groove 520 and communicates with the limiting slide rail 530. The end of the extension groove 560 connected to the limiting slide rail 530 is provided with a turning radius 561.

[0106] The steering block 570 is mounted on the limiting slide rail 530 and hinged to the limiting slider 540;

[0107] The auxiliary slide rail includes a first section 580 and a second section 581 respectively disposed on the sidewalls of the limiting slide rail 530 and the extension groove 560. The first section 580 and the second section 581 are interconnected, and auxiliary parts 582 adapted to the auxiliary slide rail are disposed on both sides of the steering block 570.

[0108] The second segment, 581, is arc-shaped.

[0109] In some embodiments of this application, by providing an extension groove 560, which is located at one end of the limiting slide rail 530 near the heating tube 210, and by providing a turning radius 561 on the extension groove 560, the turning block 570 can easily enter the extension groove 560. When the limiting slider 540 moves to its limit position, it will not enter the extension groove 560. However, since the turning block 570 is hinged to the limiting slider 540, the turning block 570 will enter the extension groove 560, thereby restricting the movement of the limiting slider 540 and preventing the limiting slider 540 from continuing to move. At this time, the push head 330 delivers the rubber-coated pressing sheet into the heating tube 210. Meanwhile, during the movement of the turning block 570 to the extension groove 560, it will always be affected by the damper 550 to ensure the stability of the movement.

[0110] Furthermore, by setting the first segment 580 and the arc-shaped second segment 581, and by setting the auxiliary component 582 on the steering block 570, the movement of the steering block 570 can be restricted, so that the steering block 570 can only enter the extension groove 560. The auxiliary component 582 can be any component that assists the movement of the steering block 570. It is recommended to use a ball bearing, which has the advantages of small contact area and low friction.

[0111] In this embodiment of the application, a buffer spring 590 is also included. The limiting slide rail 530 is provided with an inner groove 591 for placing the buffer spring 590. One end of the buffer spring 590 is connected to the inner groove 591, and the other end is connected to the steering block 570.

[0112] Furthermore, the buffer spring 590 can limit the movement of the slider 540 and the steering block 570 to buffer the movement of the support plate 420, and then buffer the movement of the push head 330. The buffer spring 590 works in conjunction with the damper 550 to further improve the buffering effect. At the same time, when the steering block 570 moves into the extension groove 560, the direction of movement of the steering block 570 changes, and the steering block 570 changes from axial movement to horizontal movement. With the cooperation of the buffer spring 590, the axial force can be dispersed to the horizontal direction, thereby improving the buffering effect and making the movement of the push head 330 more stable.
