Description

Technical Field

[0001] The invention belongs to a bladder vulcanizer, in particular to a tire bladder vulcanizer for electric vehicles and motorcycles. Background Art

[0002] At present, most bladder vulcanizers for electric vehicle and motorcycle tires use an upper-mounted oil cylinder or a lower-mounted plunger cylinder. Compared with the present invention, the bladder vulcanizers of the above two structures have major disadvantages. The bladder vulcanizer with an upper-mounted oil cylinder has a long oil cylinder stroke and a high price. Once a problem occurs in the oil cylinder, the upper structure needs to be completely removed for maintenance, which is inconvenient. Since the lower-mounted oil cylinder is located below the equipment, the installation of the equipment requires digging a foundation, and the underground foundation needs to be waterproofed, etc., which increases the cost. The oil cylinder is underground, which is inconvenient to maintain.

[0003] Therefore, it is necessary to design a tire bladder vulcanizer for electric vehicles and motorcycles that shortens the actual effective pressure stroke of the vulcanization process and reduces the use and maintenance costs. Summary of the invention

[0004] In order to overcome the shortcomings of the current tire bladder vulcanizer, such as long stroke of the long cylinder, high price and inconvenient maintenance, the technical problem is to provide a tire bladder vulcanizer for electric vehicles and motorcycles that shortens the actual effective pressure stroke of the vulcanization process and reduces the cost of use and maintenance.

[0005] The technical implementation scheme of the present invention is: a tire bladder vulcanizer for electric vehicles and motorcycles, comprising a frame, a lower support plate is fixedly connected at the lower position of the frame, first moving pairs are fixedly connected to the inner walls on both sides of the frame, each group of the first moving pairs is a structure with two moving parts, an intermediate support plate is fixedly connected between the lower moving parts of the first moving pair, an upper support plate is fixedly connected between the upper moving parts of the first moving pair, and second moving pairs are connected between the upper support plate and both sides of the intermediate support plate;

[0006] The frame is provided with a lifting device and a vulcanizing device;

[0007] Both sides of the frame are provided with lifting devices, and the lifting devices are connected to the upper support plate, and the lifting devices are used to lift the upper support plate so as to close the mold of the tire bladder between the upper support plate, the middle support plate and the lower support plate;

[0008] A vulcanizing device is provided between the upper inner walls of the frame, and a matching relationship is established between the vulcanizing device and the upper supporting plate. The vulcanizing device is used to apply pressure to the upper supporting plate to vulcanize the tire bladder.

[0009] As a preferred technical solution of the present invention, the lifting device includes electric slide rails, which are respectively fixedly connected to the outer walls on both sides of the frame, and mounting frames are fixedly connected between the moving parts of the electric slide rails, and the mounting frames are connected to both sides of the upper support plate.

[0010] As a preferred technical solution of the present invention, the vulcanization device includes a support frame, which is fixedly connected to the upper rear side of the frame, and the inner walls on both sides of the support frame are rotatably connected to a screw pair, and a moving frame is fixedly connected between the moving parts of the screw pair, and a propulsion cylinder is fixedly connected to the lower side of the moving frame.

[0011] As a preferred technical solution of the present invention, it also includes a linkage component, which is arranged between the screw pair and the mounting frame. The linkage component is used to make the screw pair rotate automatically so that the propulsion cylinder is automatically located above the upper support plate. The front side of the screw pair is fixedly connected with a transmission gear, and the mounting frame is fixedly connected with a toothed belt at a side near the transmission gear, and the toothed belt has a matching relationship with the adjacent transmission gears respectively.

[0012] As a preferred technical solution of the present invention, it also includes an adjusting component, which is arranged on the upper side of the upper support plate. The adjusting component is used to adjust the contact timing between the upper support plate and the propulsion cylinder to adjust the downward pressure of the upper support plate. A threaded sleeve is fixedly connected to the upper side of the upper support plate, and a force-bearing screw is screwed on the threaded sleeve, and the force-bearing screw cooperates with the threaded sleeve.

[0013] As a preferred technical solution of the present invention, it also includes a force-bearing component, which is arranged between the movable frame and the upper side of the frame. The force-bearing component is used to improve the stability and reliability of the propulsion cylinder when it is working, and to avoid insufficient vulcanization pressure caused by deformation of components due to the reaction force of the propulsion cylinder when it is working. A force-bearing beam is fixedly connected to the inner wall of the upper side of the frame, and an intermediate beam is fixedly connected to the upper side of the mounting frame.

[0016] The beneficial effects of the present invention are:

[0017] 1. The present invention replaces the traditional cylinder lifting method with an electric slide rail, so that the upper support plate, the middle support plate and the lower support plate do not need to use the traditional oil cylinder lifting method when closing the mold, which can shorten the stroke of the traditional oil cylinder lifting. At the same time, because the working stroke between the upper support plate, the middle support plate and the lower support plate is long, the use of the electric slide rail can reduce the processing, laying and maintenance costs. Compared with the traditional oil cylinder lifting method, the electric slide rail has the advantages of long maintenance cycle and low maintenance cost.

[0018] 2. The present invention uses a propulsion cylinder to apply pressure to the upper pallet. Compared with the traditional oil cylinder lifting method, it can shorten the vulcanization stroke of the upper pallet, the middle pallet and the lower pallet. There is no need to use the traditional oil cylinder lifting method to directly drive the upper pallet, the middle pallet and the lower pallet to lift and lower, thereby reducing costs. The propulsion cylinder only acts on the pressure generated between the upper pallet, the middle pallet and the lower pallet, which can further reduce costs compared to traditional long-stroke oil cylinders. The short-stroke propulsion cylinder has the advantages of low assembly cost and low maintenance cost.

[0019] 3. The present invention uses a mounting frame to make the toothed belt contact and drive the transmission gear during the up and down movement, so that the propulsion cylinder can be automatically positioned and withdrawn, which can improve the degree of automation of the propulsion cylinder and accurately position it, avoiding the uneven force on the tire bladder vulcanization caused by the applied pressure not being in a straight line with the center of the upper support plate.

DETAILED DESCRIPTION

[0028] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Example

[0030] like Figure 1-4 As shown, a tire bladder vulcanizer for electric vehicles and motorcycles includes a frame 1, a lower support plate 2, a first moving pair 3, an intermediate support plate 4, an upper support plate 5, a second moving pair 6, a lifting device 7 and a vulcanizing device 8. The lower side of the frame 1 is fixedly connected to the lower side of the frame 1, and the inner walls on both sides of the frame 1 are fixedly connected to the first moving pair 3. Each group of the first moving pair 3 is a structure with two moving parts. The lower side moving parts of the first moving pair 3 are fixedly connected to the intermediate support plate 4, and the upper side moving parts of the first moving pair 3 are fixedly connected to the upper support plate 5. A second moving pair 6 is connected between the upper support plate 5 and both sides of the middle support plate 4. A lifting device 7 is provided on both sides of the frame 1. The lifting device 7 is connected to the upper support plate 5. The lifting device 7 is used to lift the upper support plate 5 so that the tire bladder can be molded between the upper support plate 5, the middle support plate 4 and the lower support plate 2. A vulcanizing device 8 is provided between the inner walls of the upper side of the frame 1. The vulcanizing device 8 has a matching relationship with the upper support plate 5. The vulcanizing device 8 is used to apply pressure to the upper support plate 5 to vulcanize the tire bladder.

[0031] When this embodiment is working: when it is necessary to vulcanize the tire bladder, the tire bladder vulcanizer for electric vehicles and motorcycles can be used; the tire bladder can be placed on the lower support plate 2 and the middle support plate 4 respectively, and then the lifting device 7 is started to operate, so that the lifting device 7 drives the upper support plate 5 to move downward through the first moving pair 3, and the tire bladder between the upper support plate 5, the middle support plate 4 and the lower support plate 2 is molded through the second moving pair 6, and then the vulcanizing device 8 is controlled to move to the front side so that the vulcanizing device 8 is located above the upper support plate 5, and then the vulcanizing device 8 can be started to work so that the vulcanizing device 8 applies pressure to the upper support plate 5, and the upper support plate 5 applies pressure to the lower support plate 2 through the middle support plate 4, so that the tire bladder between the upper support plate 5, the middle support plate 4 and the lower support plate is vulcanized and formed; in this way, the vulcanization process of a pair of tire bladders is completed; then, the vulcanizing device 8 can be controlled to reset, and the upper support plate 5 is driven to reset through the lifting device 7, so that the middle support plate 4 is reset; and so on.

[0032] like Figure 4-5 As shown, the lifting device 7 includes an electric slide rail 71 and a mounting frame 72. The electric slide rail 71 is fixedly connected to the outer walls on both sides of the frame 1, and the mounting frame 72 is fixedly connected between the moving parts of the electric slide rail 71. The mounting frame 72 is connected to both sides of the upper support plate 5.

[0033] When this embodiment is working: the electric slide rail 71 can be started and its lifting can be controlled, and the moving part of the electric slide rail 71 will drive the mounting frame 72 to move up and down, thereby driving the upper support plate 5 to be lifted and lowered; the use of the electric slide rail 71 is different from the traditional cylinder lifting method, and the upper support plate 5, the middle support plate 4 and the lower support plate 2 do not need to use the traditional cylinder lifting method when closing the mold, which can shorten the stroke of the traditional cylinder lifting. At the same time, because the working stroke between the upper support plate 5, the middle support plate 4 and the lower support plate 2 is long, the use of the electric slide rail 71 can reduce the processing, laying and maintenance costs. Compared with the traditional cylinder lifting method, the electric slide rail 71 has the advantages of long maintenance cycle and low maintenance cost.

[0034] like Figure 6-7 As shown, the vulcanization device 8 includes a support frame 80, a screw pair 81, a movable frame 82 and a propulsion cylinder 83. The support frame 80 is fixedly connected to the upper rear side of the frame 1. The inner walls on both sides of the support frame 80 are rotatably connected to the screw pair 81. The movable frame 82 is fixedly connected between the movable parts of the screw pair 81, and the lower side of the movable frame 82 is fixedly connected to the propulsion cylinder 83.

[0035] When the embodiment is working, when the upper support plate 5, the middle support plate 4 and the lower support plate 2 are in the mold closing state, the screw pair 81 is rotated so that the moving part of the screw pair 81 drives the moving frame 82 to move forward, thereby driving the propulsion cylinder 83 to move forward, so that the telescopic end of the propulsion cylinder 83 is located just above the center of the upper support plate 5. At this time, the propulsion cylinder 83 is started, and the propulsion cylinder 83 drives the tire bladder between the upper support plate 5, the middle support plate 4 and the lower support plate 2 to be vulcanized. After the vulcanization is completed, the propulsion cylinder 83 can be controlled to be re-vulcanized. position, and reverse the screw pair 81 to reset it; in this way, compared with the traditional cylinder lifting method, the vulcanization stroke of the upper support plate 5, the middle support plate 4 and the lower support plate 2 can be shortened, and there is no need to adopt the traditional cylinder lifting method to directly drive the upper support plate 5, the middle support plate 4 and the lower support plate 2 to lift, which reduces the cost, and the thrust cylinder 83 only acts on the pressure between the upper support plate 5, the middle support plate 4 and the lower support plate 2. Compared with the traditional long-stroke cylinder, the cost can be further reduced, and the short-stroke thrust cylinder 83 has the advantages of low assembly cost and low maintenance cost.

[0036] like Figure 5-7 As shown, it also includes a linkage component 9, which includes a transmission gear 91 and a toothed belt 92. The linkage component 9 is arranged between the screw pair 81 and the mounting frame 72. The linkage component 9 is used to make the screw pair 81 rotate automatically so that the propulsion cylinder 83 is automatically located above the upper support plate 5. The front side of the screw pair 81 is fixedly connected with the transmission gear 91, and the mounting frame 72 is fixedly connected with the toothed belt 92 at a position near the side of the transmission gear 91. The toothed belt 92 has a matching relationship with the adjacent transmission gears 91 respectively.

[0037] When this embodiment is working: when the mounting frame 72 is in the process of descending, the mounting frame 72 will drive the toothed belt 92 to move, and when the toothed belt 92 moves downward to cooperate with the transmission gear 91, the toothed belt 92 will drive the transmission gear 91 to rotate, thereby driving the screw pair 81 to rotate, so that the propulsion cylinder 83 automatically moves to the front side and is directly above the center of the upper support plate 5; in this way, the propulsion cylinder 83 can be automatically propelled without manual operation, thereby improving the degree of automation; when the mounting frame 72 moves upward and the toothed belt 92 cooperates with the transmission gear 91, the toothed belt 92 will drive the transmission gear 91 to reverse, thereby moving the propulsion cylinder 83 to the rear side for automatic reset.

[0038] like Figure 5As shown, it also includes an adjustment component 10, which includes a threaded sleeve 101 and a force screw 102. The adjustment component 10 is arranged on the upper side of the upper support plate 5. The adjustment component 10 is used to adjust the contact timing between the upper support plate 5 and the propulsion cylinder 83 to adjust the downward pressure of the upper support plate 5. The upper side of the upper support plate 5 is fixedly connected with a threaded sleeve 101, and a force screw 102 is screwed on the threaded sleeve 101, and the force screw 102 cooperates with the threaded sleeve 101.

[0039] When this embodiment is working: the force-bearing screw 102 can be rotated in the threaded sleeve 101 to adjust the height of the force-bearing screw 102. In this way, when the thrust cylinder 83 contacts the force-bearing screw 102, the movement amount between the upper support plate 5, the middle support plate 4 and the lower support plate 2 can be changed to be suitable for different types of tire bladders, thereby improving the applicability of the tire bladder vulcanizer for electric vehicles and motorcycles.

[0040] like Figure 6-7 As shown, it also includes a force-bearing component 11, which includes a force-bearing beam 111 and a middle beam 112. The force-bearing component 11 is arranged between the moving frame 82 and the upper side of the frame 1. The force-bearing component 11 is used to improve the stability and reliability of the propulsion cylinder 83 when it is working, and to avoid the reaction force of the propulsion cylinder 83 when it is working, which causes insufficient vulcanization pressure due to deformation of the components. The force-bearing beam 111 is fixedly connected to the inner wall of the upper side of the frame 1, and the middle beam 112 is fixedly connected to the upper side of the mounting frame 72. The force-bearing beam 111 and the middle beam 112 have a matching relationship.

[0041] When this embodiment is working: when the mounting frame 72 moves to the front side, the mounting frame 72 will drive the middle beam 112 to move to the front side, so that the middle beam 112 contacts the force beam 111, so that when the propulsion cylinder 83 is working, the reaction force generated can be directly transmitted to the frame 1 through the middle beam 112 and the force beam 111, avoiding the deformation of the components at the vulcanization device 8 due to the reaction force, resulting in insufficient vulcanization pressure, and improving the stability and reliability of the propulsion cylinder 83 when working.

[0042] like Figure 6 As shown, a pressure sensor 12 is also included, and the pressure sensor 12 is fixedly connected to the lower side of the telescopic end of the propulsion cylinder 83.

[0043] When this embodiment is working: the pressure sensor 12 can monitor in real time the downward pressure when the propulsion cylinder 83 applies pressure to the upper support plate 5, so as to make the control of the propulsion cylinder 83 more precise and reduce the scrap rate of the tire vulcanization.

[0044] like Figure 6 As shown, a pulling angle code 13 is also included, and the pulling angle code 13 is fixedly connected between the frame 1 and the support frame 80.

[0045] When this embodiment is working: the pulling angle code 13 can improve the static stability and working stability of the support frame 80, and avoid the skewing and self-deformation caused by the long-term static load of the vulcanization device 8 on the support frame 80.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
