[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention. The multi-station buffer roller rubber ring press machine of the embodiment of the present invention includes:

[0034] A frame 1, a press plate 2 and a press assembly 3, wherein the press assembly 3 is mounted on the frame 1, and a telescopic end of the press assembly 3 is detachably connected to the press plate 2;

[0035] A guide assembly 4, one end of the roller to be pressed is inserted into the guide assembly 4, and a rubber ring 8 to be pressed is sleeved on the guide assembly 4, and the other end of the roller to be pressed is suitable for extending into the bottom of the frame 1 to fix the roller to be pressed;

[0036] The limiting assembly 5 has one end slidably disposed on the frame 1, and the other end of the limiting assembly 5 is detachably connected to the pressing plate 2, and the limiting assembly 5 moves along the height direction of the frame 1. The multi-station buffer roller rubber ring pressing machine of the embodiment of the present invention facilitates the installation of the roller rubber ring and improves the installation efficiency.

[0037] Specifically, Figures 1 to 9As shown, the frame 1 extends in the up-down direction, the press-fitting assembly 3 is installed at the upper end of the frame 1, and the telescopic end of the press-fitting assembly 3 is arranged in the frame 1 and connected to the press-fitting plate 2, and the press-fitting plate 2 is suitable for press-fitting the rubber ring 8 to be press-fitted onto the roller to be press-fitted. The upper end of the roller to be press-fitted extends into the guide assembly 4, and the lower end of the roller to be press-fitted extends into the frame 1 to fix the roller to be press-fitted. One end of the limit assembly 5 is slidably arranged on the frame 1, and the other end of the limit assembly 5 is detachably connected to the press-fitting plate 2, so as to facilitate the use of different press-fitting plates 2 for different rollers and rubber rings. The limit assembly 5 moves in the up-down direction, and the limit assembly 5 moves in the up-down direction to guide and limit the movement of the press-fitting plate 2 in the up-down direction, so as to prevent the press-fitting assembly 3 from driving the press-fitting plate 2 to move too far in the up-down direction, resulting in the inability to press the roller.

[0038] The guide assembly 4 is provided with the upper end of the roller to be pressed, and the upper end of the roller to be pressed at least partially extends into the guide assembly 4 to connect the guide assembly 4 with the roller to be pressed. When the telescopic end of the pressing assembly 3 moves downward, the pressing plate 2 presses the rubber ring 8 to be pressed and moves on the guide assembly 4 to the roller to be pressed to complete the pressing of the roller.

[0039] The multi-station buffer roller rubber ring press machine of the embodiment of the present invention is convenient for guiding the roller rubber ring when installing the roller rubber ring by setting a guide assembly, so as to better guide the rubber ring onto the roller during press installation. The limit assembly 5 is provided, and the limit assembly 5 is suitable for guiding and limiting the movement of the press plate 2 in the up and down directions, so as to avoid the press plate 2 from deviating when moving up and down for press installation, thereby improving the installation efficiency.

[0040] In some embodiments, the pressing plate 2 includes a plurality of ribs 21 and a pressing connecting plate 22, the pressing connecting plate 22 is provided with a plurality of pressing holes, the plurality of pressing holes are arranged at intervals in the circumferential direction of the pressing connecting plate 22, the plurality of ribs 21 are circumferentially arranged at the upper end of the pressing connecting plate 22, and the pressing connecting plate 22 is provided with a plurality of pressing holes.

[0041] Specifically, Figures 1 to 9 As shown, the size of the press-fitting hole is larger than the size of the guide assembly 4, so that the rubber ring is pressed from the guide assembly 4 to the roller to be pressed by the film pressing connecting plate 22 during press-fitting, and the limit assembly 5 is connected to the film pressing connecting plate 22 to limit the movement of the film pressing connecting plate 22 in the up and down directions. Multiple film pressing holes are arranged at intervals in the circumferential direction of the film pressing connecting plate 22 to press-fit multiple rollers to be pressed below.

[0042] The rib plate 21 plays a role in enhancing the overall rigidity and stability. The rib plate 21 can effectively disperse and withstand the force generated during the press-fitting process to prevent the press-fitting plate 2 from being deformed or damaged. The die-casting connecting plate 22 is the core part of the press-fitting plate 2, and multiple key elements are set on the die-casting connecting plate 22. The die-casting connecting plate 22 is the main interface for contact and pressure application during the press-fitting process. The die-casting connecting plate 22 is also a platform for connecting the limit assembly 5 to improve the accuracy during press-fitting.

[0043] In some embodiments, the press-fitting plate 2 further includes a press-fitting ring pad 23 , which is disposed at the lower end of the die-forming connecting plate 22 , and a plurality of press-fitting holes are disposed concentrically with the press-fitting ring pad 23 .

[0044] Specifically, Figures 1 to 9 As shown, the press-fitting ring gasket 23 contacts the rubber ring 8 to be pressed during press-fitting, so that the rubber ring 8 to be pressed is moved down and pressed onto the roller to be pressed. The press-fitting hole is concentrically arranged with the press-fitting ring gasket 23 to facilitate passing through the guide component 4 during press-fitting.

[0045] The press-fitting ring pad 23 is arranged at the lower end of the press-fitting film connecting plate 22, and directly contacts the rubber ring 8 to be press-fitted. During the press-fitting process, the pressure applied by the press-fitting plate 2 is evenly transmitted to the rubber ring through the press-fitting ring pad 23, avoiding the problem of poor press-fitting caused by uneven pressure distribution. Since the press-fitting ring pad 23 is concentrically arranged with the press-fitting hole, it actually acts as a locator, ensuring that the center position of the rubber ring during the press-fitting process is consistent with the preset position. This design helps to achieve high-precision press-fitting operations.

[0046] In some embodiments, the press-fit ring gasket 23 includes a first ring 231 and a second ring 232. The first ring 231 is sleeved on the second ring 232, and the inner wall surface of the first ring 231 is connected to the outer wall surface of the second ring 232.

[0047] The second ring 232 is made of metal, and the first ring 231 is made of polymer material.

[0048] The second ring 232 is also in contact with the rubber ring 8 to be pressed. Metal material is selected as the main component of the second ring 232 because metal has high strength and hardness and can withstand greater pressure and impact.

[0049] The material of the first ring 231 is a polymer material, for example, the material of the first ring 231 is rubber, and the press-fitting ring pad 23 also has a certain buffering effect, which can reduce the vibration and noise caused by the impact during the press-fitting process, and protect the rubber ring and the roller to be pressed from damage. The polymer material is used as the main component of the first ring 231, mainly because it has good elasticity, wear resistance and corrosion resistance. These characteristics enable the first ring 231 to better contact with the rubber ring during the press-fitting process, provide uniform pressure distribution, and reduce friction and wear between the rubber ring and the rubber ring. The elastic properties of the polymer material ring enable it to better adapt to the shape and size changes of the rubber ring, thereby providing a more uniform pressure distribution during the press-fitting process. This helps to reduce the problem of poor press-fitting caused by uneven pressure. The design of the double-layer structure enables the press-fitting ring pad 23 to adapt to the press-fitting requirements of rubber rings of different types and specifications. By adjusting the parameters such as the size, shape and material ratio of the first ring 231 and the second ring 232, the optimal matching of different press-fitting scenarios can be achieved.

[0050] Since the press-fitting ring gasket 23 adopts a double-layer structure design that is easy to replace and repair, when it is worn or damaged, only the damaged part can be replaced without replacing the entire press-fitting ring gasket 23, which reduces maintenance costs and improves production efficiency.

[0051] In some embodiments, the guide assembly 4 includes a guide sleeve 41, the guide sleeve 41 has a first hole 411 penetrating the guide sleeve 41, the first hole 411 includes a first section 4111 and a second section 4112, the radial dimension of the first section 4111 is greater than the radial dimension of the second section 4112, and the roller to be pressed at least partially extends into the second section 4112.

[0052] Specifically, Figures 1 to 9 As shown, the guide sleeve 41 has a first hole 411, and the first hole 411 passes through the guide sleeve 41 in the up-down direction, the radial dimension of the first section 4111 is larger than the radial dimension of the second section 4112, and the roller to be pressed at least partially extends into the second section 4112, thereby connecting the guide sleeve 41 at least partially with the roller to be pressed, and the roller to be pressed extends into the second section 4112 of the guide sleeve 41, providing stable support for the press-fitting process. This support effect helps to reduce vibration and deviation during the press-fitting process and improves the success rate of press-fitting. The radial dimension of the first section 4111 is larger than the radial dimension of the second section 4112 to reduce the cost and weight of the guide sleeve 41. That is, the interior of the upper half of the guide sleeve 41 is emptied, leaving a cylindrical wall thickness of sufficient strength, and reducing the weight overall.

[0053] Furthermore, the guide sleeve 41 includes a first part 412, a second part 413 and a third part 414 connected in sequence, the radial dimension of the first part 412 gradually increases in the direction away from the press plate 2, and the radial dimension of the third part 414 gradually increases in the direction away from the press plate 2. The guide sleeve 41 is a cylindrical component made of round steel, with an embedded hole for fitting with the shaft of the roller at the bottom, a guide buffer zone at the bottom outer circle, and the interior of the upper half is emptied to leave a cylindrical wall thickness of sufficient strength, thereby reducing the overall weight, and a transition chamfer is provided at the outer circle of the upper end, and the guide sleeve 41 of corresponding specifications and sizes can be manufactured according to rollers of different specifications and sizes.

[0054] The lower end of the first part 412 is connected to the upper end of the second part 413, and the lower end of the second part 413 is connected to the upper end of the third part 414. The radial dimensions of the first part 412 and the third part 414 gradually increase from top to bottom. The guide sleeve 41 is processed into a cylindrical component, and an embedded hole for fitting with the shaft of the roller is provided at the bottom to facilitate connection with the roller. A guide buffer, namely the third part 414, is also provided on the outer circle of the bottom to reduce impact and vibration during the press-fitting process.

[0055] The outer circle of the upper end of the guide sleeve 41 is provided with a transition chamfer, namely the first portion 412 , which helps to reduce the friction and resistance of the press-fitting plate 2 or the press-fitting ring gasket 23 when entering the guide sleeve 41 , thereby improving the press-fitting efficiency.

[0056] In some embodiments, the frame 1 includes a base plate 11, a plurality of columns 12 arranged at intervals circumferentially on the base plate 11, and a top plate 13, one end of the column 12 is connected to the base plate 11, and the other end of the column 12 is connected to the top plate 13, there are multiple limit assemblies 5, one end of the limit assemblies 5 is slidably set on the column 12, and the multiple columns 12 correspond one-to-one to the multiple limit assemblies 5.

[0057] Specifically, Figures 1 to 9 As shown, the rack 1 is the supporting structure of the entire equipment, and is composed of three major parts: a bottom plate 11, columns 12, and a top plate 13, which together form a stable frame for supporting and fixing other parts of the equipment. The bottom plate 11 is the base of the rack 1, and the bottom plate 11 provides a stable support surface to ensure the stability and balance of the entire rack 1. The bottom plate 11 is usually made of a solid material, such as a steel plate or cast iron, to withstand various loads when the equipment is running.

[0058] The columns 12 are vertical components connecting the bottom plate 11 and the top plate 13. They are evenly distributed around the bottom plate 11, that is, arranged at intervals around the edge of the bottom plate 11. The number and layout of the columns 12 are determined according to the design requirements of the rack 1 and the size of the equipment to ensure the rigidity and stability of the rack 1. One end of the column 12 is firmly connected to the bottom plate 11, and the other end is connected to the top plate 13 to form a stable frame structure.

[0059] The top plate 13 is located at the top of the rack 1 and is connected to the top of the column 12. The function of the top plate 13 is to provide support and fixing points for the components on the top of the equipment, and also to help increase the overall rigidity and stability of the rack 1.

[0060] There are multiple limiter assemblies 5, which correspond to the number of columns 12. This means that each column 12 is equipped with a limiter assembly 5 to achieve limiter control in different directions. This layout ensures the stability and safety of the rack 1 in all directions.

[0061] The press-fitting assembly 3 includes a hydraulic electric pump 31 and a cylinder assembly 32. The cylinder assembly 32 is mounted on the top plate 13. The hydraulic electric pump 31 is connected to the cylinder assembly 32 to provide power to the cylinder assembly 32. The cylinder assembly 32 includes a cylinder 321 and a flange 322. The cylinder 321 is an outsourced part. A piston-type cylinder 321 is selected. A flange 322 matched with the frame 1 is welded at the cylinder mouth of the cylinder 321. A die connection plate for assembling a three-station die is welded at the rod head of the piston rod of the cylinder 321. A rib plate 21 is welded at the die connection plate 22 and the rod head of the piston rod of the cylinder 321 to increase the compressive strength of the die connection plate. The die connection plate is also connected to the limit assembly 5 so as to limit and guide the die connection plate 22 when it moves up and down.

[0062] Furthermore, the overall structure of the frame 1 is an open regular triangle frame 1, which is welded by the top plate 13, the annular flange 322, the column 12, the reinforcing rib plate 21, the bottom plate 11, the foot, and the reinforcing rib plate 21, and one column 12 is inserted into the anti-deviation device. The center of the annular flange 322 must be concentric with the center point of the bottom plate 11, and the three columns 12 are evenly distributed vertically on the same circumference, forming a regular triangle distribution. The upper and lower ends of the columns 12 are respectively connected and welded to the annular flange 322 and the bottom plate 11.

[0063] A top plate 13 is arranged on the annular flange 322 , a foot and a reinforcing rib plate 21 are arranged below the bottom plate 11 , and three triangular reinforcing rib plates 21 are arranged outside the three columns 12 connected to the bottom plate 11 .

[0064] In some embodiments, the limiting assembly 5 includes a collar 51 and a limiting connecting plate 52 . The collar 51 is sleeved on the column 12 . One end of the limiting connecting plate 52 is connected to the collar 51 , and the other end of the limiting connecting plate 52 is detachably connected to the press plate 2 .

[0065] Specifically, Figures 1 to 9As shown, the collar 51 moves in the up-down direction on the frame 1, and the collar 51 moves along the up-down defense line on the column 12. The collar 51 is an annular component, which is sleeved on the column 12 and can move freely in the up-down direction on the column 12. The inner diameter of the collar 51 is slightly larger than the outer diameter of the column 12 to ensure that the collar 51 can slide smoothly without getting stuck. The material of the collar 51 is usually selected to be wear-resistant, corrosion-resistant and has a certain strength to withstand the vibration and impact during the operation of the equipment. One end of the limiting connecting plate 52 is connected to the collar 51, and this connection can be a bolt connection or other forms of fixed connection to ensure that the connection is firm and reliable. The other end of the limiting connecting plate 52 is detachably connected to the pressing plate 2. This design allows the position of the pressing plate 2 to be replaced or adjusted when necessary. The main function of the limiting connecting plate 52 is to transmit the position information of the collar 51 on the column 12 to the pressing plate 2, thereby limiting the range of motion of the pressing plate 2.

[0066] The detachable connection design between the limit connecting plate 52 and the pressing plate 2 increases the flexibility and maintainability of the device. This connection mode allows the pressing plate 2 to be replaced or adjusted separately without replacing the entire limit assembly 5. At the same time, it is also convenient to replace or adjust the pressing plate 2 when the device is maintained or upgraded.

[0067] In some embodiments, the multi-station buffer roller rubber ring press also includes a flange jig 6, which has a plurality of second holes arranged circumferentially at intervals, and the roller to be pressed at least partially extends into the second hole to fix the roller to be pressed, and the flange jig 6 is detachably mounted on the base plate 11. The flange jig 6 is provided with a plurality of second holes arranged circumferentially at intervals, and these holes are designed to accommodate and fix the rollers to be pressed. At least part of the roller (usually the shaft part) will extend into these second holes, and the roller will be firmly fixed to the flange jig 6 by bolts. The flange jig 6 is used to fix the roller to be pressed to prevent the roller from moving or rotating during the pressing process, thereby ensuring the accuracy and stability of the pressing. Through the second holes arranged circumferentially at intervals, the flange jig 6 can fix multiple rollers at the same time, realize simultaneous pressing at multiple stations, and improve production efficiency.

[0068] In some embodiments, the outer peripheral surface of the guide sleeve 41 is smooth so as to reduce the wear and resistance of the rubber ring 8 to be pressed during press-fitting, thereby improving the smoothness and stability of press-fitting.
