Description

TECHNICAL FIELD

[0001] The present application belongs to the field of vulcanized rubber, and relates to the technical field of automatic demolding, in particular to a track pin vulcanization and rubber-hanging demolding device and a demolding method. BACKGROUND

[0002] The track is mainly responsible for providing a continuous track for the weight wheel, improving its passing ability on complex ground, and ensuring the normal driving of the armored vehicle. The track mainly consists of track plates and track pins. With the continuous development of asphalt pavement and tank technology, all-metal tracks have gradually withdrawn from the stage of history, and rubber-hanging tracks have gradually become mainstream. It is worth mentioning that as long as any part of the track has rubber hanging, it can be called a rubber-hanging track.

[0003] The pin ear rubber-hanging technology refers to filling rubber in the pin ear part, which can improve the engagement quality of the track and the driving wheel, increase the service life of the track, and reduce noise. The general manufacturing method of the pin ear rubber-hanging technology is to bond a rubber ring on the track pin, and the rubber ring and the track pin are pressed into the pin ear together, and the tightness requirement is that the rubber ring cannot rotate in the pin ear even if there is enough friction. The assembled hinge, the rubber can fill the entire space of the pin ear. The most common double-pin track in the current tank basically adopts this technology, so the manufacturing of rubber-hanging track pins has become a top priority.

[0004] Because the rubber-hanging pin ear is easily subjected to great traction and pressure during driving, it is a consumable part, so it needs to be regularly inspected and replaced during daily training. However, the current market processing flow of the rubber-hanging pin ear is generally to pre-form the rubber material, then fill it into the track pin for mold pressing and vulcanization production, and then manually polish and process, each link is manually operated, the automation level is low, there are many human factors in each link, and the product quality risk is large.

[0005] Retrieved patent: An automatic demolding rubber vulcanization device (Chinese patent application number: 201310135416.X, application date: April 18, 2013), the device sets guide rails and baffles on the lower heating plate, so that the lower mold plate is fixed in position after being pushed into the lower heating plate of the vulcanizing machine, and at the same time the upper mold plate is fixed in the upper heating plate, so that the upper and lower heating plates of the vulcanizing machine realize the demolding and closing of the mold during opening and closing, replacing the original manual operation to separate the upper and lower molds to take out.

[0006] Patent: A demolding robot and method for a rubber pipe production line (Chinese patent application number: 201910717837.0, application date: January 12, 2019), the first clamping assembly is mainly used to press the rubber pipe that needs to be demolded during the demolding process. During the pressing process, the clamping plate is driven by the clamping cylinder to press the rubber pipe on the carrying table, ensuring the normal demolding process.

[0007] The above device can assist the vulcanized rubber to be smoothly removed from the mold, but when mass production is required, it is time-consuming and laborious to take out the demolded rubber from the mold. At the same time, since the demolded object is inconsistent with the structure of the glued pin ear, it cannot meet the demolding requirements of the glued pin ear. Therefore, in the field of glued pin ear, vulcanization and demolding integration still needs to be greatly improved to reduce the labor intensity of workers, avoid damage to the mold, and quickly improve production efficiency.

The demolding device is designed according to the characteristics of the track pin, and the whole process is operated mechanically without manual taking of the glued track pin, further ensuring the safety of workers during operation and avoiding damage to the mold caused by falling track pins.

[0055] Example 1

[0056] Combination Figure 1 The track pin vulcanization and demolding device in this embodiment includes a frame, on which a vulcanization section 1, a demolding section 2, and a release section 3 are mounted. The frame comprises several interconnected frame components, connected by bolts, welding, and plug-in methods. The vulcanization section 1 is used to vulcanize and coat the track pin 43 with rubber. The track pin 43 includes a pin hole 41, such as... Figure 5 As shown, most track pins on the market include pin holes, and this device can be adapted to various track pin models; the vulcanizing section 1 includes several heating plates 11, and a set of rubber-coated track pin mold is set between two heating plates 11. The number of heating plates 11 is not limited here, but depends on the production scale; the rubber-coated track pin mold includes an upper mold 12 and a lower mold 13, and the mold size is matched with the track pin.

[0057] Combination Figure 2 The demolding part 2 is fixedly connected to the vulcanizing part 1. The demolding part 2 includes a through rod 23. The diameter of the through rod 23 is slightly smaller than the diameter of the pin hole 41. It is used to fix the rubber-coated track pin 4 when the vulcanizing part 1 is opened. The number of through rods 23 depends on the maximum number of rubber-coated track pin molds that the vulcanizing part 1 can hold. The through rods 23 are fixedly set on the connecting plate 24. The through rods 23 are perpendicular to the connecting plate and are evenly arranged. The fixing method is welding or threaded connection. All through rods 23 can reciprocate synchronously between the pin hole 41 and the demolding part 2.

[0058] Preferably, each rubber-coated track pin mold is provided with a demolding part 2, and all rubber-coated track pins 4 after vulcanization can be demolded in batches and simultaneously to achieve mass production of rubber-coated track pins.

[0059] The mold release section 3 includes a guard plate 34, which reciprocates within the frame and is used to hold the adhesive track pin 4 after demolding by the through rod 23. At this time, the height of the guard plate 34 is lower than that of the through rod 23. In different devices, the direction of movement of the heating plate 11 when the mold is opened is different. Since the through rod 23 is fixed on the heating plate 11, the through rod 23 will move with the heating plate 11. As a result, the relative position of the guard plate 34 and the through rod 23 will also change. Therefore, this embodiment does not limit the initial relative position of the guard plate 34 and the through rod 23. Each rubber-coated track pin mold is equipped with a protective plate 34, which can be a rectangular flat plate. In this embodiment, the protective plate 34 is preferably composed of multiple strips to ensure the device is lightweight. Optionally, a surrounding plate is provided at the edge of the protective plate 34 to further prevent the rubber-coated track 4 from rolling off. The protective plate 34 is used to receive the rubber-coated track pin after it is demolded by the through rod after the mold is opened. There is no need for manual handling of the rubber-coated track pin, which further ensures the safety of workers during operation and prevents the track pin from falling and damaging the mold.

[0060] Since both the through rod 23 and the guard plate 34 in this embodiment are linear motions, their specific driving methods are not limited. The rotational motion can be converted into linear motion through transmission elements such as gear racks, lead screws and nuts, or it can be driven by a linear drive motor, or it can be directly generated by the piston of a cylinder or hydraulic cylinder. Alternatively, a pull rod can be used to manually pull the through rod 23 and the guard plate 34.

[0061] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.

[0062] Example 2

[0063] Combination Figure 3 The track pin vulcanization and rubber coating demolding device of this embodiment is a further optimization of embodiment 1. The demolding part 2 includes a baffle 21 with several round holes through which the through rod 23 can pass. The center of the round holes and the center of the pin hole 41 are on the same horizontal plane. The baffle 21 can further restrict the rubber-coated track pin 4 from moving laterally with the through rod 23. Otherwise, during the demolding process, the rubber-coated track pin 4 may be pulled out of the vulcanization part 1 by the through rod 23. The round holes on the baffle 21 can guide the direction of the through rod and prevent malfunctions due to misalignment of the through rod during the demolding process, thus ensuring the stability of the machine operation.

[0064] like Figure 3As shown, the baffle 21 is equipped with a demolding cylinder 22, which drives the through rod 23 to reciprocate. The cylinder drive structure is simple, lightweight, and easy to maintain. The piston of the demolding cylinder 22, at its end away from the baffle 21, is bolted to the connecting plate 24 via an extension plate 25. The length of the extension plate 25 is not less than the single movement length of the through rod 23. Solid steel through rods 23, smaller than the pin holes 41 of the track pins, are evenly fixed to the connecting plate 24. The baffle 21 is equipped with a through rod track 26, which has a track groove. The through rod track 26 is movably connected to the connecting plate 24. The connecting plate 24 can translate relative to the through rod track 26. Figure 4 A rod guide 27 is provided between the rod guide rail 26 and the connecting plate 24. A roller 28 is provided at the end of the rod guide 27 away from the connecting plate 24. The roller 28 can roll in the track groove in the rod guide rail 26.

[0065] Combination Figure 5 In this embodiment, the guard plate 34 is fixedly connected to the guard plate slide rod 35, and the guard plate slide rod 35 is movably connected to the guard plate track 31. The guard plate slide rod 35 is provided with rollers 28, which can roll in the guard plate track 31. The guard plate 34 is driven to reciprocate by the guard plate cylinder 37.

[0066] In summary, in this embodiment, both the threading rod 23 and the protective plate 34 are driven by cylinders, and fully automated and efficient demolding is achieved through the linkage between the PLC and the vulcanizing machine. The steps, measures, and schemes in the various operations, methods, processes, and procedures discussed in this embodiment can be alternated, modified, combined, or deleted.

[0067] Example 3

[0068] Based on the above embodiments, the track pin vulcanization rubber coating and demolding device of this embodiment, combined with Figure 6 After vulcanization, the rubber-coated track pin 4 has a vulcanized rubber ring 42. The unvulcanized rubber material is a viscous fluid under high temperature and pressure. When it reaches the molding vulcanization stage, the rubber material quickly fills the mold cavity. The excess part (in order to prevent insufficient rubber, the rubber material filling the mold cavity must maintain a certain excess) overflows the vulcanization overflow, forming flash.

[0069] Specifically, in this embodiment, a gap is provided at the mating point of the upper mold 12 and lower mold 13 of the rubber-coated track pin mold. The thickness of the flash on the end face of the rubber ring 42 vulcanized by the rubber-coated track pin mold is 0.1-0.3 mm. If the flash thickness is less than 0.1 mm, the rubber-coated track pin mold and the track pin are prone to collision, damaging the mold. If the flash thickness is greater than 0.3 mm, due to the high strength properties of the rubber material, it becomes very difficult to manually tear the edge, resulting in a significant reduction in work efficiency. The axial flash thickness of the rubber ring 42 is preferably 0.05-0.1 mm. The axial flash occurs at the parting position of the rubber-coated track pin mold. Since the parting surface of the rubber-coated track pin mold will not contact the track pin at this time, the flash thickness can be limited to less than 0.1 mm. A flash thickness of more than 0.05 mm reduces the risk of insufficient rubber.

[0070] Furthermore, the thickness of the flash on the end face of the rubber ring 42 is preferably 0.15-0.25mm, and the width is 3mm. The outer dimension of the flash on the end face is not restricted, and a height difference is formed with the thickness of the flash on the end face. This height difference can be used for quick tearing of the edge later, thereby improving the tearing efficiency.

[0071] This embodiment optimizes the vulcanization dimensions of the rubber-coated track pin mold, facilitating manual trimming after automatic demolding. It eliminates the need for tool cutting and grinding, allowing for direct manual tearing of the edges, thus comprehensively improving the production efficiency of rubber-coated track pins.

[0072] Example 4

[0073] Based on the above embodiments, the heating plate 11 of the track pin vulcanization rubber coating demolding device in this embodiment has three layers, which are, from top to bottom, a first heating plate, a second heating plate, and a third heating plate. For example... Figure 2 As shown, between the first and second heating plates, and between the second and third heating plates, each is equipped with a set of rubber-coated track pin molds; the second heating plate can simultaneously vulcanize two sets of track pins. This structure is convenient and reasonable, with all three heating plates working simultaneously for batch vulcanization of track pins. Figure 1 As shown, a demolding part 2 is fixed on the first heating plate, and a demolding part 2 is also fixed on the second heating plate. The demolding parts work simultaneously to demold the vulcanized track pins; combined with Figure 1 and Figure 5 In this embodiment, there are two guard plates: a first guard plate 32 and a second guard plate 33. The two guard plates are fixedly connected by a support rod 36 and are driven by a guard plate cylinder 37 to reciprocate within the frame. The guard plates can be linked simultaneously by a simple support rod 36, without the need to set separate drive cylinders. The structure is simple and the manufacturing cost is greatly reduced.

[0074] The specific arrangement of the track pin vulcanization rubber coating demolding device described above is only a partial embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.

[0075] Example 5

[0076] This embodiment relates to a method for demolding vulcanized rubber-coated track pins, including the following steps:

[0077] S1: Vulcanizing section 1 is opened. Track pin 43 and rubber material are placed in the upper mold 12 and lower mold 13 of the rubber-coated track pin mold. Through rod 23 and guard plate 34 are located outside vulcanizing section 1. The track pin in this step is a common track pin with pin holes on the market.

[0078] S2: The mold for the rubber-coated track pin is closed; the heating plate 11 pressurizes and vulcanizes the rubber material, while the through rod 23 and the guard plate 34 remain stationary. A gap is provided at the mating point of the mold 12 and the lower mold 13 to facilitate subsequent manual edge tearing.

[0079] S3: Vulcanization of vulcanization section 1 is completed. The upper mold 12 and the lower mold 13 are still in the mold-closed state. The through rod 23 is inserted into the pin hole 41 of the rubber-coated track pin 4 to fix the rubber-coated track pin 4. The guard plate 34 remains stationary. The through rod 23 is driven by the demolding cylinder 22. It first passes through the hole on the baffle 21 and is guided by the hole to pass into the pin hole 41 of the rubber-coated track pin 4.

[0080] S4: The upper mold 12 separates from the lower mold 13, the guard plate 34 moves to below the through rod 23, and the through rod 23 returns to its original position, which is the position of the through rod 23 in step 1; during the movement of the through rod 23, the horizontal movement of the rubber-coated track pin 43 is restricted by the baffle 21, the through rod 23 retracts from the hole on the baffle 21 to the initial position, the through rod 23 and the pin hole 41 separate, the rubber-coated track pin 43 falls after losing the support of the through rod 23, and the guard plate 34 catches the rubber-coated track pin 4.

[0081] S5: The protective plate 34 returns to its original position, which is the position of the protective plate 34 in step 1. The worker removes the rubber-coated track pin 4, manually tears off the edge, and then repeats steps S1-S4. In this step, the protective plate 34 is positioned away from the heating plate 11 in the vulcanization section 1, effectively avoiding the risk of burns to the workers.

[0082] Example 6

[0083] As a specific optimization of Example 5, this example involves a method for demolding vulcanized rubber-coated track pins, including the following steps:

[0084] S1: Select the appropriate rubber-coating track pin mold according to the type of track pin that needs to be vulcanized; the rubber-coating track pin mold is installed between the two heating plates 11 of the vulcanization section 1.

[0085] S2: The technician opens the vulcanizing section 1 using the operating device, and places the track pin 43 and rubber material into the upper mold 12 and lower mold 13 of the rubber-coated track pin mold. The through rod 23 and the guard plate 34 are located outside the vulcanizing section 1. The track pin in this step is a common track pin with pin holes on the market.

[0086] S3: The mold for the rubber-coated track pin is closed; the heating plate 11 pressurizes and vulcanizes the rubber material, while the through rod 23 and the guard plate 34 remain stationary. A gap is provided at the mating point of the mold 12 and the lower mold 13 to facilitate subsequent manual edge tearing.

[0087] S4: Vulcanization of vulcanization section 1 is completed. The upper mold 12 and lower mold 13 are still in the mold-closed state. The PLC (sequence controller) sends a drive command to the demolding cylinder 22. The demolding cylinder 22 retracts and pulls the connecting plate 24 through the extension plate 25. The through rod 23 moves synchronously with the connecting plate 24. The through rod 23 first passes through the hole on the baffle 21, and then is guided by the hole to pass into the pin hole 41 of the rubber-coated track pin 4. During this process, the center of the hole on the baffle 21, the through rod 23 and the pin hole 41 are on the same horizontal plane.

[0088] To improve the efficiency of the rod 23, a rod track 26 is connected to the baffle 21. The rod track 26 has a track groove. A rod slide 27 is provided between the rod track 26 and the connecting plate 24. A roller 28 is provided at the end of the rod slide 27 away from the connecting plate 24. When the rod 23 moves in translation, the roller 28 rolls in the track groove of the rod track 26, reducing the resistance generated by the rod 23 during the movement.

[0089] S5: The upper mold 12 separates from the lower mold 13. The PLC-linked guard plate cylinder 37 rolls in the guard plate track 31 via rollers and moves to directly below the through rod 23. The through rod 23 returns to its original position, which is the position of the through rod 23 in step 1. During the movement of the through rod 23, the rubber-coated track pin 43 is restricted from horizontal movement by the baffle 21. The through rod 23 retracts from the hole on the baffle 21 to the initial position. The through rod 23 and the pin hole 41 separate. The rubber-coated track pin 43 falls after losing the support of the through rod 23. The guard plate 34 catches the rubber-coated track pin 4.

[0090] This step solves the problem of manually removing each rubber-coated track pin from the mold using a pry bar after vulcanization, preventing the rubber-coated track pins from falling and damaging the mold. It also improves work efficiency and helps in the mass production of rubber-coated track pins.

[0091] S6: The protective plate 34 returns to its original position, which is the position of the protective plate 34 in step 1. The worker removes the rubber-coated track pin 4, manually tears off the edges, and then repeats steps S1-S4. In this step, the protective plate 34 is positioned away from the heating plate 11 in the vulcanization section 1, effectively avoiding the risk of burns to the workers.
