Description

Technical Field

[0001] The present application relates to the technical field of thermal-break aluminum processing, and in particular to a thermal-break aluminum toothed strip threading machine and a strip threading method. Background Art

[0002] The thermal insulation aluminum strip inserting machine is a device specially used for producing thermal insulation aluminum alloy door and window profiles. Thermal insulation aluminum is an aluminum alloy material with heat insulation performance. Its structure consists of inner and outer aluminum profiles separated by heat insulation materials (usually nylon strips or PVC strips). The function of the strip inserting machine is to embed the heat insulation strip between the inner and outer layers of the aluminum profile through a certain pressure and process, thereby forming a thermal insulation aluminum profile with heat insulation function.

[0003] In the process of using the existing strip threading machine, the aluminum profile needs to be placed into the equipment first, and the insulation strip needs to be manually inserted from one end of the aluminum profile. During the strip threading process, the double servo toothed cutter teeth the aluminum profile and pushes the profile to move, so that the insulation strip gradually enters the installation groove of the aluminum profile.

[0004] However, in order to ensure that the dual servo cutter is accurately aligned with the two insulation strip installation slots of the aluminum profile, the current equipment operation requires multiple manual adjustments: 1. Guide roller adjustment: The guide roller needs to be adjusted manually to center the aluminum profile on the operating table so that the aluminum profile can pass through the serrated knife accurately.

[0005] 2. Manually control the dual servo serrated knife: The operator adjusts the position of the serrated knife through the hand wheel to ensure that the serrated knife is aligned with the center line of the installation groove of the aluminum profile and applies appropriate pressure.

[0006] 3. Fixing of thermal insulation strip: After the aluminum profile passes through the serrated cutter, the thermal insulation strip is manually inserted into one end of the aluminum profile. Then, the height of the positioning block is adjusted so that the thermal insulation strip enters the positioning groove. Then, the clamping cylinder pushes the clamping block in the positioning groove to fix the thermal insulation strip.

[0007] During this operation, especially the adjustment of the dual servo slitters and the clamping mechanism, it is necessary to repeatedly adjust the distance of the slitters and the height of the positioning blocks so that the slitters are aligned with the center line of the aluminum profile installation slot and the insulation strip is fixed. This repeated manual operation has low efficiency and low control and adjustment accuracy. Summary of the invention

[0008] In order to improve the adjustment accuracy and efficiency of the thermal break aluminum toothed stripping, thereby improving the production efficiency of the thermal break aluminum, the present application provides a thermal break aluminum toothed stripping machine and a stripping method.

[0009] The present application provides a thermally-broken aluminum toothed strip threading machine that adopts the following technical solution: A thermal-break aluminum toothing strip threading machine, comprising a mounting platform, a positioning roller assembly and two toothed knife assemblies, wherein the positioning roller assembly enables the aluminum profile to be accurately centered in the operating area, the toothed knife assembly is driven by a moving assembly to move along the X-axis and Z-axis directions, the moving assembly is slidably connected to a moving block, the moving block is driven by a first servo drive unit to move along the Z-axis direction, the moving block is provided with a plug-in slot for inserting an end of a heat insulation strip, the plug-in slot is arranged opposite to the toothed end of the toothed knife assembly, the two toothed knife assemblies are arranged opposite to each other, and the moving block is provided with a pressing assembly for pressing the heat insulation strip against the plug-in slot; The apparatus further comprises a first detection block, which is driven by a second servo drive unit to move along the X-axis direction, and a first displacement sensor and a second displacement sensor are arranged on the first detection block, wherein a probe of the first displacement sensor is arranged vertically downward, and a probe of the second displacement sensor is arranged along the X-axis direction; It also includes a second detection block and a third displacement sensor, the second detection block is driven to move along the Z-axis direction by a third servo drive unit, the third displacement sensor is used to detect the distance between the second detection block and the mounting table, the second detection block is provided with a fourth displacement sensor, the probe of the fourth displacement sensor is arranged along the X-axis direction and toward the central axis of the mounting table, and the probe of the fourth displacement sensor is flush with the bottom of the second detection block, and the moving block is provided with a fifth displacement sensor, and the fifth displacement sensor is flush with the top wall of the plug-in slot and points to the mounting table.

[0010] By adopting the above technical solution, during the adjustment process, the aluminum profile is passed through the positioning roller assembly, so that the aluminum profile is centered on the mounting table and passes under the serrated knife assembly. Then, by controlling the movement of the first detection block, the data measured by the first displacement sensor and the second sensor are recorded, and the distance between the center line of the mounting groove of the aluminum profile and the center line of the aluminum profile and the depth of the mounting groove of the aluminum profile are automatically calculated by the system. The moving assembly drives the serrated knife assembly to move according to the above calculated data, so that the toothed end of the serrated knife assembly is aligned with the center line of the mounting groove of the aluminum profile, and appropriate pressure is applied. Then, the heat insulation strip is manually inserted into the end of the aluminum profile extending through the discharge end of the serrated knife, and then the second detection block is controlled to move, and the distance between the second detection block and the mounting table is measured when the fourth displacement sensor is aligned with the top of the heat insulation strip, and then the moving block is controlled to perform distance detection while the fifth displacement sensor is simultaneously controlled until the plug-in slot is aligned with the heat insulation strip, and then the heat insulation strip is manually pushed into the plug-in slot, and the pressing assembly is controlled to press against the heat insulation strip, and the serrated knife can be started to perform toothing and strip insertion. This precise adjustment avoids the errors caused by frequent manual adjustment in traditional equipment, improves operating accuracy, reduces the frequency and time of human intervention, improves adjustment efficiency, and thus improves production efficiency.

[0011] Optionally, the positioning roller assembly includes two sliding seats arranged opposite to each other, the sliding seats are slidably connected to the mounting platform, a rotating roller is rotatably connected to the sliding seat, two fixed seats are arranged opposite to each other in the mounting platform, the two sliding seats are located between the two fixed seats, the sliding seat is connected to a movable plate, the movable plate is slidably arranged in the fixed seat, the movable plate separates the interior of the fixed seat into an adjustment chamber and an oil injection chamber, a return spring is installed in the adjustment chamber, and the two sliding seats are commonly connected with a linkage for controlling the synchronous relative movement of the two.

[0012] By adopting the above technical solution, it is only necessary to manually push the aluminum profile from between the two rotating rollers. The two rotating rollers will move away from each other synchronously under the action of the linkage. At this time, the reset spring is in a compressed state, and then hydraulic oil is injected into the oil filling chamber to complete the centering adjustment of the aluminum profile.

[0013] This design does not require manual movement and locking of the rotating roller, and can quickly ensure that the aluminum profile is in a centered state. After the aluminum profile leaves the rotating roller, the reset spring drives the rotating roller to automatically reset, and no manual reset is required. At the same time, the design of the oil filling chamber can reduce the shaking of the aluminum profile during the advancement process or the shaking of the rotating roller due to the unevenness of its side, so that the aluminum profile can be stably threaded and the tooth opening deviation is reduced, thereby improving the adjustment efficiency and adjustment accuracy.

[0014] Optionally, the linkage includes two racks and a gear, the two racks are respectively connected to the two sliding seats, the gear is rotatably arranged on the mounting platform, and the two racks are arranged opposite to each other and are both meshed with the gear.

[0015] By adopting the above technical solution, when one rack drives the gear to rotate, the gear pushes the other rack to move, thereby realizing synchronous relative movement of the two rotating rollers, ensuring that the two rotating rollers are always symmetrically arranged about the center line of the mounting platform.

[0016] Optionally, the moving assembly includes a mounting column, the mounting column is arranged on the mounting platform, the mounting column is slidably provided with a Z-axis moving seat, the Z-axis moving seat is driven by a fourth servo drive unit, an X-axis moving seat is installed on the Z-axis moving seat, the X-axis moving seat is driven by a fifth servo drive unit, the serrated knife assembly and the first servo drive unit are both installed on the X-axis moving seat, and the moving block is slidably connected to the X-axis moving seat.

[0017] Optionally, the serrated cutter assembly includes a drive motor and a serrated cutter disc, the drive motor is connected to a reducer, the drive motor and the reducer are installed on the moving assembly, the drive motor is connected to the serrated cutter disc, and the two serrated cutter discs are arranged opposite to each other.

[0018] Optionally, the abutting and tightening assembly comprises a first abutting block and a second abutting block, and a first sliding groove and a second sliding groove are provided in the moving block; The first abutment block is connected to a first slide plate, the first slide plate is slidably disposed in the first slide slot, the first slide plate divides the first slide slot into a first pressurizing area and a first adjustment area, the first adjustment area is provided with a first spring, the first spring is connected to the first slide plate, and the first abutment block extends from an inner top wall of the insertion slot; The second abutment block is connected to a second slide plate, which is slidably arranged in the second slide groove. The second slide plate divides the second slide groove into a second pressurized area and a second adjustment area. The second adjustment area is installed with a second spring, which is connected to the second slide plate. The second abutment block extends from the inner side wall of the plug-in groove.

[0019] By adopting the above technical solution, when the thermal insulation strip is inserted into the plug-in slot, the first abutment block abuts against the top of the thermal insulation strip and extends into the first adjustment area, the second abutment block abuts against one side of the thermal insulation strip and extends into the second adjustment area, and then hydraulic oil is injected into the first pressurizing area and the second pressurizing area, so that the first abutment block, the second abutment block and the side wall of the plug-in slot facing the second abutment block abut against the thermal insulation strip together, thereby fixing the thermal insulation strip.

[0020] Moreover, since the plug-in slot needs to reserve a plug-in margin when it is automatically adjusted, otherwise the top of the plug-in slot will be directly flush with the top of the thermal insulation strip, which may cause the thermal insulation strip to be unable to be smoothly inserted into the plug-in slot. Therefore, the design of the first abutment block cooperates with the first spring to meet the system's requirements for different plug-in margins, such as 3 / 4 / 5mm, thereby ensuring that the thermal insulation strip can smoothly enter the plug-in slot.

[0021] Optionally, the surfaces of the first abutting block and the second abutting block that abut against the thermal insulation strip are both configured as guiding arc surfaces.

[0022] Optionally, a first support roller, a second support roller and a third support roller are installed on the mounting platform, the positioning roller assembly is located between the first support roller and the second support roller, and the first support roller and the second support roller are each rotatably arranged at one end of the mounting platform.

[0023] By adopting the above technical solution, multi-point support for the aluminum profile is achieved, so that the aluminum profile can be smoothly advanced, while reducing the cross-sectional area of ​​the aluminum profile during the advancement process and reducing the wear on the bottom of the aluminum profile.

[0024] A method for cutting off the tooth of aluminum strips, which is applied to the above-mentioned machine for cutting off the tooth of aluminum strips, comprises the following steps: S1. Pass the aluminum profile under the serrated cutter and center the aluminum profile; S2, controlling the first detection block to move, and the first displacement sensor and the second displacement sensor cooperate to measure: the distance between the center line of the installation groove of the aluminum profile and the center line of the aluminum profile is X1, and the data when the first displacement sensor points to the bottom wall of the installation groove of the aluminum profile is Z1; S3, control the initial position of the serrated cutter so that the bottom end of the serrated cutter is flush with the probe of the first displacement sensor, control the two serrated cutters to move away from each other by an amount X1 along the X-axis direction, and then control the two serrated cutters to move downward by a distance of Z1+1 / 2 / 3mm; S4. Insert a heat insulation strip into the end of the aluminum profile that extends beyond the discharge end of the toothed cutter; S5, control the second detection block to move until the fourth displacement sensor probe is flush with the top of the thermal insulation strip, the third displacement sensor measures that the distance between the second detection block and the mounting platform is X2, and control the moving block to move until the distance between the top wall of its plug-in slot and the mounting platform is X2+3 / 4 / 5mm; S6. Insert the heat insulation strip into the insertion slot, control the clamping assembly to clamp the heat insulation strip, and start the toothing knife to perform toothing and strip insertion.

[0025] By adopting the above technical solution, in step S3, the two serration cutters are controlled to move relatively away from X1 along the X axis by the measured X1 and Z1, and the serration cutters are controlled to move downward along the Z axis. This step ensures the adjustment accuracy of the serration cutters, and by moving the serration cutters downward by Z1+1 / 2 / 3mm, excessive or insufficient serration of the aluminum profile is avoided, thereby optimizing the serration effect; In steps S4 and S5, the second detection block and the fourth displacement sensor are used to accurately measure the height of the thermal insulation strip, and the X2+3 / 4 / 5mm margin design is used to ensure that the thermal insulation strip can be smoothly inserted into the plug-in slot, and to avoid the situation where the plug-in slot and the thermal insulation strip are in direct contact and cannot be inserted. This margin design allows a certain adjustment space to ensure that the thermal insulation strip can be smoothly inserted into the aluminum profile. The entire tooth-cutting and strip-threading process is automatically and precisely controlled with less human intervention, which improves the adjustment accuracy and efficiency of the tooth-cutting and strip-threading of the thermally-broken aluminum, thereby improving the production efficiency of the thermally-broken aluminum.

[0026] Optionally, in step S2, the first detection block is controlled to move, and the initial data of the first displacement sensor is recorded as z1, the first data change of the first displacement sensor is recorded as z2, the second data change of the first displacement sensor is recorded as z3, the third data change of the first displacement sensor is recorded as z4, and the fourth data change of the first displacement sensor is recorded as z5; When recording z2, the second displacement sensor simultaneously records data x1; when recording z3, the second displacement sensor simultaneously records data x2; when recording z4, the second displacement sensor simultaneously records data x3; when recording z5, the second displacement sensor simultaneously records data x4; The distance between the center line of the installation groove of the aluminum profile and the center line of the aluminum profile is X1=(x1-x4) / 2-[(x2-x3) / 2+(x1-x2)]; When the first displacement sensor points to the bottom wall of the aluminum profile installation groove, the data is Z1=z3.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. Record multiple data changes of multiple displacement sensors, and the equipment automatically adjusts the position of the toothed knife assembly and the plug slot. This precise adjustment avoids the error of frequent manual adjustment in traditional equipment, improves operation accuracy, reduces the frequency and time of human intervention, improves adjustment efficiency, and thus improves production efficiency; 2. It can quickly ensure that the aluminum profile is in the military state, and after the aluminum profile leaves the rotating roller, the reset spring drives the rotating roller to automatically reset, and no manual reset is required. At the same time, the design of the oil injection chamber can reduce the shaking of the aluminum profile during the advancement process or the shaking of the rotating roller due to the unevenness of its side, so that the aluminum profile can be stably threaded and the tooth opening deviation is reduced, thereby improving the adjustment efficiency and adjustment accuracy; 3. Since the plug-in slot needs to reserve a plug-in margin when it is automatically adjusted, otherwise the top of the plug-in slot will be directly flush with the top of the thermal insulation strip, which may cause the thermal insulation strip to be unable to be smoothly inserted into the plug-in slot. Therefore, the design of the first abutment block cooperates with the first spring to meet the requirements of the system setting different plug-in margins, thereby ensuring that the thermal insulation strip can smoothly enter the plug-in slot.

A detection plate 19 is also installed at one end of the first frame 14. The first detection block 15 is located above the first support roller 11. A first displacement sensor 16 is installed at the bottom of the first detection block 15. A second displacement sensor 17 is installed on one side of the first detection block 15. The probe of the first displacement sensor 16 is vertically downwardly arranged and points to the first support roller 11, and the probe of the second displacement sensor 17 is arranged along the X-axis direction and points to the detection plate 19.

[0042] like Figure 4 Two sprocket knife assemblies 3 are also installed on the mounting platform 1. The two sprocket knife assemblies 3 are symmetrically arranged about the center line of the length direction of the mounting platform 1. The toothed ends of the two sprocket knife assemblies 3 are located above the second supporting roller 12. The mounting platform 1 is provided with a moving assembly 4 for driving the sprocket knife assembly 3 to move along the X-axis and Z-axis directions.

[0043] like Figure 2 , Figure 5 and Figure 6 A moving block 5 is slidably provided on the side of the moving component 4 away from the toothed knife component 3, and the moving block 5 is provided with a plug-in slot 51.

A first servo drive unit 41 for driving the moving block 5 to move along the Z-axis direction is installed on the moving component 4, and the toothed end of the toothed knife component 3 is arranged opposite to the plug-in slot 51. The moving component 4 can drive the toothed knife component 3 and the moving block 5 to move synchronously, and the moving block 5 can move along the Z-axis direction on the moving component 4 alone.

[0045] During the adjustment process, the aluminum profile passes through the positioning roller assembly 2 so that the aluminum profile is centered on the mounting table 1 and passes under the slit knife assembly 3. Then, the first detection block 15 is controlled to move, and the data measured by the first displacement sensor 16 and the second displacement sensor 17 are recorded. The system automatically calculates the distance between the center line of the mounting groove of the aluminum profile and the center line of the aluminum profile and the depth of the mounting groove of the aluminum profile. The moving assembly 4 drives the slit knife assembly 3 to move according to the above calculated data, so that the toothed end of the slit knife assembly 3 is aligned with the center line of the mounting groove of the aluminum profile, and appropriate pressure is applied.

This precise adjustment avoids the error of frequent manual adjustment in traditional equipment, improves the operating accuracy, reduces the frequency and time of human intervention, improves the adjustment efficiency, and thus improves the production efficiency.

[0046] like Figure 7 The positioning roller assembly 2 includes two sliding seats 21 arranged opposite to each other. The sliding seats 21 are slidably connected to the mounting platform 1.

[0047] It is only necessary to manually push the aluminum profile through the two rotating rollers 22. The two rotating rollers 22 will move away from each other synchronously under the action of the connecting member 26. At this time, the return spring 25 is in a compressed state, and then hydraulic oil is injected into the oil filling chamber 232 to complete the centering adjustment of the aluminum profile.

[0048] This design does not require manual movement and locking of the rotating roller 22, and can quickly ensure that the aluminum profile is in a centered state. After the aluminum profile leaves the rotating roller 22, the reset spring 25 drives the rotating roller 22 to automatically reset, and no manual reset is required. At the same time, the design of the oil filling chamber 232 can reduce the shaking of the aluminum profile during the advancement process or the shaking of the rotating roller 22 due to the unevenness of its side, so that the aluminum profile can stably perform the strip threading work and reduce the occurrence of tooth opening deviation, thereby improving the adjustment efficiency and adjustment accuracy.

When the fifth servo drive unit 46 is started, the toothed cutter disc 32 and the moving block 5 can be synchronously moved along the X-axis direction.

[0051] like Figure 8 The abutting and tightening assembly 6 includes a first abutting block 61 and a second abutting block 62. A first slide groove 52 and a second slide groove 53 are provided in the moving block 5. The first slide groove 52 penetrates the inner top wall of the plug-in slot 51, and the second slide groove 53 penetrates the inner side wall of the plug-in slot 51. The second slide groove 53 is arranged on the side of the plug-in slot 51 away from the center line of the length direction of the mounting platform 1; The first abutting block 61 is connected with a first slide plate 63, which is slidably disposed in the first slide groove 52.
