Description

Aluminum profile rolling die

Technical Field

The utility model relates to the technical field of calendering equipment, in particular to an aluminum profile calendering die.

Background Art

Calendering is one of the important basic processes in polymer material processing, and is also one of the important processing methods for some semi-finished and finished products. Aluminum profile calendering is the process of passing aluminum profile raw materials through a series of horizontal rollers rotating in opposite directions, so that the materials are subjected to extrusion and extension to become thin sheet products with a certain thickness, width and smooth surface.

When using the existing aluminum profile rolling dies, in order to process aluminum profiles of different thicknesses, it is often necessary to change the size of the rollers, thereby changing the distance between the rollers. However, since the rollers of the rolling dies are located at a high position and have a large mass, it is difficult to lift the rollers when replacing them, and manual replacement is time-consuming and labor-intensive. Therefore, in recent years, a mold that can automatically adjust the distance between the rollers has gradually appeared on the market. It is driven by a chain and a sprocket. When automatically adjusting the distance between the two rollers, an external tensioning mechanism is used to tighten the chain and the sprocket to ensure normal transmission.

However, although this equipment solves the problem of adjusting the distance between the pressing rollers, when processing aluminum profiles in batches, the same set of molds is used for a long time, which can easily cause excessive use and wear of the molds, thereby reducing the service life of the molds. Therefore, although it is troublesome to replace the pressing rollers, for long-term production, timely replacement of the calendering mold is more of a protection for the mold itself. Therefore, we designed and proposed an aluminum profile calendering mold.

The two storage bins 2 are both provided with bin doors on the outside. Spare pressure rollers 3 are arranged inside the storage bins 2 to facilitate storage and flexible use according to processing requirements, and to replace the spare pressure rollers 3 corresponding to the aluminum profile to be processed.

A positioning plate 4 is fixedly connected to one end of the top of the base 1, a gear box 5 is fixedly connected to the outer side of the positioning plate 4, a first motor 6 is fixedly connected to the outer side of the gear box 5, a driving shaft of the first motor 6 passes through the gear box 5 and is fixedly connected to a first gear 7, a second gear 8 is arranged at the bottom of the first gear 7, a mounting plate 9 is fixedly connected to the center of the side of the first gear 7 and the second gear 8 away from the first motor 6, and a mounting shaft 10 is fixedly connected to the center of the side of the mounting plate 9 away from the positioning plate 4.

Among them, the first gear 7 and the second gear 8 are meshingly connected, the first gear 7 and the second gear 8 are of the same size and have the same number of teeth, the mounting disk 9 and the positioning plate 4 are connected by bearings, and through the transmission between the first gear 7 and the second gear 8, it is convenient to drive the two mounting disks 9 to rotate synchronously at the same time, and drive the corresponding mounting shaft 10 to rotate.

A linear motor 11 is arranged at one end of the top of the base 1, and an axis changing mechanism 12 is arranged at the top of the linear motor 11. The axis changing mechanism 12 includes a slide 13 fixedly connected to the top of the driving end of the linear motor 11, and a second motor 14 is fixedly connected to one side of the outer wall of the slide 13. The driving shaft of the second motor 14 passes through the slide 13 and is fixedly connected to a support arm 15.

A pressure roller sleeve 16 is provided on the side of the support arm 15 away from the second motor 14. The end bearing of the pressure roller sleeve 16 is connected to a turntable 19. The pressure roller sleeve 16 can rotate on one side of the turntable 19. A positioning bolt 20 is provided on the outer wall of the support arm 15. The positioning bolt 20 passes through the support arm 15 and is threadedly connected to the center of the turntable 19 to facilitate fixing the pressure roller sleeve 16 on the support arm 15.

Among them, a number of annular positioning protrusions 17 are fixedly connected to the edge of the mounting plate 9, and a groove 18 corresponding to the positioning protrusion 17 is opened at one end of the pressure roller sleeve 16 close to the positioning protrusion 17, which is convenient for sleeve-mounting the pressure roller sleeve 16 on the mounting shaft 10 and docking with the mounting plate 9 so that it can rotate synchronously.

In this embodiment, two support arms 15 are provided, and one end of the two support arms 15 is fixedly connected. The two support arms 15 are vertically arranged. When the pressure roller sleeve 16 on one of the support arms 15 is correspondingly sleeved with the installation shaft 10, the other support arm 15 is horizontally arranged, which is convenient for the staff to assemble it at a lower position without lifting the pressure roller for installation, which is more convenient and labor-saving.

When in use, first connect the first motor 6, the second motor 14 and the linear motor 11 to an external power supply. According to the rolled size of the aluminum profile to be processed, install the corresponding roller sleeve 16 on the support arm 15 (there are multiple groups of roller sleeves 16, and the outer diameters of different roller sleeves 16 are different. When two roller sleeves 16 are sleeved on the mounting shaft 10, the distance between the two roller sleeves 16 is the output size of the aluminum profile after rolling, and these roller sleeves 16 with different outer diameters are placed in the storage bin 2 as spare rollers 3).

Then, the linear motor 11 is started to drive the shaft changing mechanism 12 to move on the top of the base 1, so that the pressure roller sleeve 16 is sleeved on the outside of the installation shaft 10 and continues to move forward. During this period, the first motor 6 can drive the installation disk 9 to rotate at a low speed to adjust the position of the positioning protrusion 17 until the positioning protrusion 17 and the groove 18 are correspondingly fitted and plugged in, or through external PLC programming, the installation disk 9 is accurately controlled to stop, so that the positioning protrusion 17 can just be plugged in with the groove 18.

At this time, the first motor 6 is started to drive the first gear 7 to rotate, the second gear 8 to rotate, the two mounting plates 9 to rotate, and then the two mounting shafts 10 and the roller sleeves 16 outside thereof to rotate toward each other, so that the aluminum profile passing between the two can be rolled. This device can be used in conjunction with an external conveying mechanism when working. Here, a conveyor belt is used as an example. The aluminum profile is conveyed between the two rollers through the conveyor belt, and the aluminum profile is rolled and formed under the rolling action of the roller molds.

During the calendering operation, the staff can open the storage bin 2, take out the spare roller 3, and install it on another support arm 15 in the above-mentioned installation method. At this time, the support arm 15 is horizontally arranged and its position is only slightly higher than the top of the base 1, which is convenient for the staff to perform assembly operations.

When it is necessary to replace a calendering mold of a different size, it is only necessary to start the linear motor 11 to detach the original pressure roller sleeve 16 from the mounting shaft 10, and then start the second motor 14 to drive the support arm 15 to rotate ninety degrees, and the pressure roller sleeve 16 to be replaced can be sleeved on the outside of the mounting shaft 10. During this period, there is no need for manual replacement by the staff, which saves processing time and has high replacement efficiency.

When the device is in use, roller sleeves 16 of the same size can be installed on the two support arms 15. During processing, the molds can be switched and used alternately to avoid long-term use of the same set of roller sleeves 16 and excessive wear, thereby extending the service life of related components.

Compared with the existing pressure roller, the device adopts an outer sleeve type pressure roller sleeve 16. When the pressure roller is damaged, only the sleeve needs to be replaced, and the internal mounting shaft 10 can continue to be used, and the consumable cost is relatively low.

The coordinated work among the first motor 6, the second motor 14 and the linear motor 11 in the present device can be realized by external PLC programming, which is the prior art and will not be described in detail here.

Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources.
