Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of broken bridge aluminum processing, in particular to a broken bridge aluminum toothed bar inserting machine and a bar inserting method. BACKGROUND

[0002] The broken bridge aluminum bar inserting machine is a device specially used for producing broken bridge aluminum alloy door and window profiles. The broken bridge aluminum is an aluminum alloy material with heat insulation performance, and its structure is separated by heat insulation materials (usually nylon strips or PVC strips) between the inner and outer aluminum profiles. The function of the bar inserting machine is to embed the heat insulation strips between the inner and outer layers of the aluminum profile through certain pressure and process, so as to form the broken bridge aluminum profile with heat insulation function.

[0003] In the use process of the existing bar inserting machine, the aluminum profile needs to be placed into the device first, and the heat insulation strip needs to be manually inserted from one end of the aluminum profile. In the bar inserting process, the double servo toothed knives open the teeth of the aluminum profile and push the profile to move, so that the heat insulation strip gradually enters the installation groove of the aluminum profile.

[0004] However, in order to ensure that the double servo toothed knives accurately align with the two heat insulation strip installation grooves of the aluminum profile, the current device operation needs to be adjusted manually for many times:

[0005] 1. Guide roller adjustment: the guide roller needs to be adjusted manually to make the aluminum profile centered on the operation table, so that the aluminum profile can pass through the toothed knives accurately.

[0006] 2. Manual control of double servo toothed knives: the operator adjusts the position of the toothed knives through the hand wheel to ensure that the toothed knives are aligned with the center line of the installation groove of the aluminum profile, and appropriate pressure is applied.

[0007] 3. Fixing of the heat insulation strip: after the aluminum profile passes through the toothed knives, the heat insulation strip is inserted into one end of the aluminum profile manually. Then, the height of the positioning block is adjusted to make the heat insulation strip enter the positioning groove. Then, the clamping cylinder pushes the abutting block in the positioning groove to fix the heat insulation strip.

[0008] In this operation process, especially the adjustment of the double servo toothed knives and the clamping mechanism, the distance of the toothed knives and the height of the positioning block need to be adjusted repeatedly to make the toothed knives aligned with the center line of the installation groove of the aluminum profile and the heat insulation strip fixed. This repeated manual operation has low adjustment efficiency and low control and adjustment accuracy. SUMMARY

[0026] Moreover, since the insertion slot needs to reserve an insertion allowance during automatic adjustment, otherwise the top of the insertion slot is directly flush with the top of the heat insulation strip, which may cause the heat insulation strip to fail to be smoothly inserted into the insertion slot, therefore, the design of the first abutting block matched with the first spring meets the requirement of different insertion allowances of the system, for example, 3 / 4 / 5mm, so as to ensure that the heat insulation strip can be smoothly inserted into the insertion slot.

[0045] 2. The aluminum profile can be quickly ensured to be in the military state, and after the aluminum profile leaves the rotating roller, the rotating roller is automatically reset by the reset spring, without the need for manual reset. At the same time, the design of the oil injection chamber can reduce the shaking of the aluminum profile during the advancing process or the shaking of the rotating roller due to the uneven side of the aluminum profile, so that the aluminum profile can stably perform the threading work, reduce the notching deviation, and thus improve the adjustment efficiency and adjustment precision;

[0046] 3. Since the insertion groove needs to reserve an insertion allowance during automatic adjustment, otherwise the top of the insertion groove is directly flush with the top of the thermal insulation strip, which may cause the thermal insulation strip to fail to be smoothly inserted into the insertion groove, therefore, the design of the first abutting block cooperating with the first spring meets the requirement of different insertion allowances set by the system, so as to ensure that the thermal insulation strip can be smoothly inserted into the insertion groove.
