Description

Technical Field

[0001] This invention relates to the field of tire manufacturing technology, and more specifically, to a forming drum housing and a forming machine. Background Technology

[0002] There are two types of forming drums for sleeve-type air spring forming machines: tile expansion and contraction forming drums and blow-suction forming drums. The tile expansion and contraction forming drum works by expanding when the airbag is attached and contracting when the drum is unloaded. The blow-suction forming drum has evenly distributed air holes around its circumference. Its working principle is vacuum adsorption when the airbag is attached and air is blown through the air holes when the drum is unloaded.

[0003] Currently, the diameter of the forming drum for sleeve-type air springs is generally 60-150mm. However, due to structural limitations, the tile-type forming drum cannot be adapted to small sizes, i.e., the diameter must not be less than 85mm. Therefore, to produce small-sized air springs, it is necessary to switch to a blow-and-suction forming drum, while large-sized air springs generally use tile-type forming drums. Since the two types of forming drums work on different principles, they require different power units for driving, resulting in higher operating costs. Furthermore, equipment needs to be changed in the production of air springs of different sizes, which wastes time. Summary of the Invention

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To address the problems of large size and low efficiency in existing molding machines, this invention provides a molding drum housing and a molding machine.

[0024] Please refer to Figures 1 to 3The forming drum housing provided by this invention can be used with different types of forming drums and can also achieve multi-functionality. Compared with current housings, it has wider versatility and higher efficiency. Specifically, the forming drum housing includes: a frame 10, a drive mechanism 20, a first positioning shaft assembly 11, and a second positioning shaft assembly 12. The drive mechanism 20 is mounted on the frame 10. The drive mechanism 20 is driven to rotate the first positioning shaft assembly 11, wherein the first positioning shaft assembly 11 is used to connect with the first forming drum 30. The drive mechanism 20 is also driven to rotate the second positioning shaft assembly 12, wherein the second positioning shaft assembly 12 is used to connect with the second forming drum 40. The drive mechanism 20 of this invention can drive the first positioning shaft assembly 11 and the second positioning shaft assembly 12 to rotate separately, or it can drive the first positioning shaft assembly 11 and the second positioning shaft assembly 12 to rotate simultaneously.

[0025] In addition, the first positioning shaft assembly 11 and the second positioning shaft assembly 12 can be integrated, which is equivalent to the same shaft extending out of both sides of the frame 10.

[0026] The second forming drum 40 of the present invention is a blow-suction forming drum. Therefore, the forming drum housing also includes a ventilation assembly 50, which is connected to the second forming drum 40 to expand and contract the second forming drum 40 by inflating and deflating it. The ventilation assembly 50 also includes an air pump, a vacuum pump, and a venting pipe. The air pump is used to inflate the venting pipe, and the vacuum pump is used to draw air in. When the tire carcass is attached, the vacuum pump draws air in to make the tire carcass adhere tightly to the second forming drum 40. When the tire is removed, the air pump blows air into the venting pipe.

[0027] The first forming drum 30 of the present invention is an expansion and contraction forming drum. For this purpose, the forming drum housing is also provided with a pushing assembly 60, which is drivenly connected to the first forming drum 30 to drive the first forming drum 30 to expand and contract. The pushing assembly 60 includes: a plurality of pushing cylinders 61 and a pushing plate 62. The plurality of pushing cylinders 61 are arranged opposite to each other on the side of the frame 10 near the first forming drum 30. The pushing plate 62 is slidably sleeved on the first positioning shaft assembly 11 and connected to the expansion and contraction mechanism 32 of the first forming drum 30. The plurality of pushing cylinders 61 are respectively drivenly connected to the pushing plate 62 to simultaneously drive the pushing plate 62 to move along the axial direction of the first positioning shaft assembly 11.

[0028] like Figure 1 As shown, the pushing component 60 of the present invention includes two opposing pushing cylinders 61, which are respectively connected to the upper and lower ends of the pushing plate 62. The pushing plate 62 is a disc. The two pushing cylinders 61 extend and retract simultaneously to push the pushing plate 62 to move, thereby driving the expansion and contraction mechanism 32 to expand and contract.

[0029] The forming drum machine housing also includes multiple optical shafts 63, which are spaced apart on the side of the push plate 62 away from the push cylinder 61, and are used to connect to the expansion and contraction mechanism 32 respectively.

[0030] The drive mechanism 20 includes a drive motor, which is detachably connected to the first positioning shaft assembly 11 and / or the second positioning shaft assembly 12 to drive the first positioning shaft assembly 11 or the second positioning shaft assembly 12 to rotate.

[0031] The drive mechanism 20 of the present invention can be implemented in the following three ways: Method 1: The drive motor is connected to the two positioning shaft assemblies respectively through a clutch, so as to selectively drive the first positioning shaft assembly 11 and the second positioning shaft assembly 12; Method 2: The drive motor is connected to the first positioning shaft assembly 11 and the second positioning shaft assembly 12 simultaneously to drive the first positioning shaft assembly 11 and the second positioning shaft assembly to rotate synchronously; Method 3: The present invention provides two drive motors, which are respectively driven to drive the first positioning shaft assembly 11 and the second positioning shaft assembly 12. The drive motors are connected to the first positioning shaft assembly 11 through a transmission belt and a gear set on the first positioning shaft assembly 11 to drive the first positioning shaft assembly 11 to rotate. The drive form of the second positioning shaft assembly 12 is the same as that of the first positioning shaft assembly 11.

[0032] To avoid interference between the movement of the first forming drum 30 and the second forming drum 40, the first positioning shaft assembly 11 and the second positioning shaft assembly 12 of the present invention are arranged on opposite sides of the frame 10 and are at the same horizontal height.

[0033] The present invention also provides a molding machine, including a first molding drum 30, a second molding drum 40 and the above-mentioned molding drum housing, wherein the molding drum housing is drivenly connected to the first molding drum 30 and the second molding drum 40 respectively.

[0034] The first forming drum 30 of the forming machine of the present invention is an expansion and contraction forming drum, and the second forming drum 40 is a blow-suction forming drum. The forming drum machine box can drive the first forming drum 30 to work and can also drive the second forming drum 40 to work.

[0035] Specifically, the first forming drum 30 includes a first spindle assembly 31 and an expansion and contraction mechanism 32. The first spindle assembly 31 is connected to the first positioning shaft assembly 11. The expansion and contraction mechanism 32 is drivenly connected to the push assembly 60 of the forming drum housing. The expansion and contraction mechanism 32 includes multiple tile assemblies arranged around the first spindle assembly 31. The push assembly 60 is drivenly connected to the expansion and contraction mechanism 32 to simultaneously drive the multiple tile assemblies to move radially along the first spindle assembly 31. The tile assembly includes a first tile and a second tile, which are of different sizes.

[0036] The outer surface of the second forming drum 40 is provided with multiple vent holes. The venting component 50 on the forming drum machine box is connected to the multiple vent holes respectively. The venting component 50 is provided with a solenoid valve for controlling the inflation or deflation of the venting component 50.

[0037] like Figure 1 As shown, the novel sleeve-type air spring forming machine housing provided by the present invention has a first forming drum 30 located on the left side of the frame 10. The first positioning shaft assembly 11 is connected to the tile expansion and contraction type first forming drum 30 through three optical shafts 63. The push cylinder 61 is connected to the tile expansion and contraction mechanism 32. The push cylinder 61 extends and returns to push the tile expansion and contraction mechanism 32 to move, thereby driving the tile expansion and contraction type forming drum to expand and contract.

[0038] The ventilation component 50 is located on the right side of the chassis and is directly connected to the second positioning shaft assembly 12 of the chassis. The ventilation component 50 leads out an air pipe and is connected to the second forming drum 40 of the blowing and suction type, thereby realizing adsorption and blowing during bonding.

[0039] When producing large-sized sleeve-type air spring airbags, a first forming drum 30 with tile expansion and contraction is used. The main process steps of the novel sleeve-type air spring forming machine housing of the present invention are as follows:

[0040] 1) Connect the first spindle assembly 31 of the forming drum to the first positioning shaft assembly 11 of the chassis with screws;

[0041] 2) Connect the forming drum pusher plate 62 to the pusher plate 62 of the tile expansion and contraction mechanism 32 through three optical shafts 63;

[0042] 3) Push the cylinder 61 to extend, push the tile expansion and contraction mechanism 32 to move to the left, and the forming drum push plate 62 moves to the left accordingly;

[0043] 4) The first forming drum 30 tiles of the tile expansion and contraction type move outward, and the diameter increases, thereby completing the expansion of the forming drum;

[0044] 5) After bonding is completed, push cylinder 61 back, drive tile expansion and contraction mechanism 32 to move to the right, and molding drum push plate 62 moves to the right accordingly;

[0045] 6) The tile-shaped drum expands and contracts as the tiles move inward, reducing their diameter, thus completing the shrinkage of the drum.

[0046] 7) Remove the airbag to complete the airbag forming process.

[0047] When producing small-sized sleeve-type air spring airbags, a blow-and-suction type second forming drum 40 is used. The main process steps of the novel sleeve-type air spring forming machine housing described in this invention are as follows:

[0048] 1) Connect the second spindle assembly of the forming drum to the second positioning shaft assembly 12 of the machine housing with screws;

[0049] 2) Connect the air pipe leading out from the ventilation assembly 50 to the quick-connect fitting of the second molding drum 40;

[0050] 3) Adjust the solenoid valve to the suction state for bonding;

[0051] 4) After bonding is complete, adjust the control solenoid valve to the air blowing state;

[0052] 5) Disconnect the sleeve-type air spring airbag from the second molding drum 40;

[0053] 6) Remove the airbag to complete the airbag formation process.

[0054] like Figure 2 , Figure 3 As shown, the new sleeve-type air spring forming machine is equipped with a tile expansion and contraction type first forming drum 30 and a blow-suction type second forming drum 40.

[0055] The chassis of this invention is compatible with both expansion and contraction type and blow-suction type molding drums, thus solving the problem that the two types of molding drums require two different chassis structures. It is also simple and convenient to disassemble, enabling quick replacement of the two types of drums, greatly saving equipment space, reducing production costs, and avoiding wasted time.
