Description
Technical Field
The invention relates to the field of aluminum profiles, in particular to an aluminum profile machining system.
Background
In the processing after the aluminum profile is extruded, two cooling media which are often used are compressed air and atomized cooling water, and the two spray heads are often required to be simultaneously equipped according to different cooling requirements for switching use. In the low temperature environment in the north, because the heat preservation environment of some factory buildings is not good, at the minor-diameter spray hole of the cooling water spray head, even if the spray head is vertically arranged, part of water still cannot be smoothly discharged when the operation is stopped, accumulated water of the spray hole is easy to freeze and block, and the condition that the cooling water cannot be normally sprayed after the spray hole is restarted is caused.
The aluminum profile extrusion refers to a technique of forcibly extruding an irregular aluminum ingot through an extrusion channel having a specific shape by using an extrusion plate, and then cutting the extruded aluminum profile from an outlet of the extrusion channel by using a cutter, thereby obtaining an aluminum profile having the same cross-sectional shape as that of the extrusion channel.
After accomplishing an extrusion operation, often need clear up the remaining aluminum product in the extrusion passageway out, just can carry out next extrusion operation, the remaining aluminium alloy can directly be extruded and fall into one process next in the extrusion passageway when otherwise extruding next time, but this partial aluminium alloy length can not satisfy the requirement, can't the direct use. The residual aluminum profile in the existing extrusion channel is cleaned basically by manual operation, so that time and labor are wasted, and the influence on automatic upgrading is large.
Simultaneously, the inventor researches and discovers that because the extruded aluminum profile is higher in temperature and has certain viscidity between the blade, the blade often happens to cut off the condition that the aluminum profile can not fall into the bearing plate fast, and the viscidity of the aluminum profile of different sizes and temperatures to the blade is different, therefore, when researching and developing the automatic extrusion channel back-pushing cleaning structure, the mode of the back-pushing cleaning structure can not be started after the fixed time length that the blade is cut off, otherwise, the back-pushing cleaning structure is easily caused to miss the aluminum profile, the aluminum profile is damaged, a new mode is needed to accurately judge the time that the blade falls into the bearing plate, and the back-pushing cleaning structure can be started.
In extreme cases, the aluminum profile may be completely adhered to the blade surface and cannot fall into the receiving plate, in which case, the aluminum profile must be interfered by external force to slide smoothly.

The working principle is as follows: firstly, placing a hot aluminum ingot B into a shell 1, driving a first hydraulic cylinder 3 to enable an extrusion plate 4 to extrude the aluminum ingot B rightwards, and extruding the aluminum ingot B through an extrusion channel 2 to obtain a cylindrical aluminum profile A; the pneumatic cylinder 11 is driven to rapidly cut the blade 5 downwards to cut the aluminum profile A out, after cutting, if the aluminum profile A smoothly slides down the bearing disc 6, the temperature detected by the outer temperature sensor 17 is far less than the temperature detected by the inner temperature sensor 16, the temperature difference between the two is more than a set value K, and the gravity sensor 26 detects that the weight is obviously increased, the mechanical arm 25 is controlled to move away the bearing disc 6 to carry the aluminum profile A to the next process, then the motor 20 is started to rotate the rotating block 59 outwards for 180 degrees to the position shown in figure 8, the knife groove 18 is opened (the width of the knife groove 18 is not less than the diameter of the extrusion channel 2 and is preferably slightly more than the diameter of the extrusion channel 2), the second hydraulic cylinder 29 is driven to move downwards to the position where the cleaning push plate 7 is aligned with the extrusion channel 2, the cleaning pneumatic cylinder 31 is driven to push the cleaning push plate 7 into the extrusion channel 2, the aluminum profile remained in the extrusion channel 2, then, the shutter door 13 is opened, and the residual aluminum ingots in the housing 1 fall into the recycling bin 10 to be recycled.
If the aluminum profile A cannot smoothly slide down, the temperature difference between the inner temperature sensor 16 and the outer temperature sensor 17 is smaller than a set value K, and the weight value of the gravity sensor 26 is unchanged, and after the situation continuously exceeds a set time t, the electric telescopic rod 52 is driven to extend the trigger push plate 8 into the slide way 37 to push the air guide block 35 and the air closing block 33 to move right until the infrared generator 46 aligns with the first infrared sensor 47 (namely the position of the middle diagram in FIG. 13) and sends an infrared signal to the first infrared sensor, so that the air closing block 33 originally blocking the air outlet 50 is pushed away, each air guide hole 36 of the air guide block 35 is communicated with the air outlet 50, after the controller 58 receives the infrared signal of the first infrared sensor 47, the electromagnetic valve 54 is opened, the compressed air heated by the recovery box 10 is sequentially conveyed to the air injection hole 51 from the air inlet pipe 49, the air outlet 50 and the air guide hole 36, and after the air injection is carried out to, if the aluminum profile A slides down under the pressure of compressed air (namely the temperature difference and the value of the gravity sensor meet the sliding judgment condition), the trigger push plate 8 is retracted leftwards, the air guide block 35 and the air closing block 33 return under the action of the first spring 38 in the process, and then the operations of removing the bearing disc 6, opening the cutter groove 18 and pushing back for cleaning are continuously executed according to a set program; if the temperature difference and the gravity sensor value still do not meet the slip judgment condition after the fixed air injection time, the trigger push plate 8 is continuously pushed leftwards until the infrared generator 46 is aligned with the second infrared sensor 48 (i.e. the position of the lowest figure in fig. 13), in the process, the inclined press plate 45 can extrude the inclined plane 44 to enable the cylinder 43 and the descending plate 9 to move downwards against the pulling force of the second spring 41 and knock down the aluminum profile a, after knocking down, the trigger push plate 8 is withdrawn, and the air-lock block 33 and the descending plate 9 are reset under the action of the first spring 38 and the second spring 41 respectively (the restoring force of the first spring 38 is stronger than that of the second spring 41, so that the air-lock block 33 is prevented from being clamped).
Has the advantages that: 1. the ice breaking device has the advantages that the ice breaking operation can be carried out by utilizing compressed air when the cooling water atomizing nozzle is blocked, the operation is convenient, the structure is simple, and independent external ice breaking power is not needed.
2. The extrusion channel back-pushing cleaning mechanism is researched and developed, automatic cleaning of residual aluminum profiles in the extrusion channel can be effectively achieved, and the trouble of manual cleaning is avoided.
3. The invention discloses a three-layer type blade integrated rotating block, which is characterized in that a two-stage series judgment structure of a temperature difference and gravity sensor is designed by utilizing the separation of a heat insulation ceramic plate, and compared with the design of fixed time length, the judgment mode can effectively overcome the problem that an extrusion channel back-pushing cleaning mechanism moves down too early under the condition of sticking a cutter, so that an aluminum profile is damaged.
4. The blade anti-sticking trigger structure of the single-line three-position type is developed, switching of three different positions of air closing, compressed air injection and falling of a falling plate is achieved through a trigger push plate in linear motion, switching action is simple and reliable, a blowing-off mode of non-rigid contact force can be preferentially provided for an adhered aluminum profile, and then a forced falling mode of rigid contact force is provided, so that the aluminum profile can reliably slide off at last, and the possibility that the aluminum profile is not damaged is guaranteed to the maximum extent.
5. Through the waste heat that utilizes the collection box, heat for compressed air, can reduce the difference in temperature between spun compressed air and the aluminium alloy, prevent that the aluminium alloy from being cooled down excessively, lead to extrusion passageway return to push away clearance mechanism mistake, the judgement setting value K that has also avoided the difference in temperature need be set for a great numerical value and just can prevent extrusion passageway return to push away clearance mechanism mistake (K is big more, then outer temperature sensor need descend to lower numerical value and just can trigger extrusion passageway return to push away clearance mechanism, then the aluminium alloy is after normally slipping, need longer time just can trigger extrusion passageway return to push away clearance mechanism, be unfavorable for shortening work flow, therefore K should not be too big). Regarding the specific values of the temperature difference determination setting value K, the compressed air blowing time length, the determination setting time length t, and the like, considering that the conditions of aluminum profiles with different sizes and temperatures are different, the specific values are not provided any more in this embodiment, and the specific values are selected by a person in the art according to the specific conditions.
