Description

Technical Field

[0001] The present invention relates to the technical field of profile production equipment, and particularly relates to a multi-profile production line with one extrusion head. Background Art

[0002] With the increasingly wide application of aluminum alloy materials, the requirements for their quality and performance are also getting higher and higher. The extrusion molding of industrial aluminum profiles has relatively high production efficiency and stable profile quality, so it is widely used. When the aluminum profile is extruded by an extruder, its temperature is relatively high and it is relatively soft. A tractor is needed to pull the profile to prevent the aluminum profile from being deformed due to self-weight accumulation. The extruded profile is cut into material segments by a sawing device. The profile material segments are cooled and shaped while being tightened at both ends by a straightening machine to prevent deformation or other surface defects. With the maturity of the multi-profile extrusion technology, the extrusion efficiency of simultaneously extruding multiple profiles by an extruder has been greatly improved compared with the extrusion of a single profile. However, the existing aluminum profile extrusion production lines can only meet the extrusion production of single profiles. Multiple profiles are prone to misalignment and overlap during the production process, which has an adverse impact on the forming quality of the profiles. Especially during straightening and forming, the waste rate is relatively high when the profiles overlap. In the existing production lines, manual material sorting and feeding operations are required between various devices to avoid the overlap of multiple profiles, which is time-consuming and laborious. Moreover, even if the production personnel timely discover the overlap of multiple profiles, it is very difficult to correct, which has a great impact on the production efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a multi-profile production line with one extrusion head to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0004] The technical solution adopted to solve the above technical problems:

[0005] A multi-profile production line with one extrusion head includes: an extrusion and conveying line, a traction saw, a straightening machine, a tractor, and two material handling devices;

[0006] The extrusion and conveying line extends in the front-rear direction. The traction saw is arranged on the left side of the front section of the extrusion and conveying line. The straightening machine is arranged on the left side of the rear section of the extrusion and conveying line. The tractor includes two traction devices, and both of the two traction devices are arranged on the right side of the extrusion and conveying line. The material handling device is arranged above the extrusion and conveying line;

[0007] The traction saw, the traction device, and the material handling device are all provided with multi-station fixtures. The multi-station fixture includes an upper clamping part and a lower clamping part. The upper clamping part and the lower clamping part are arranged up and down. The upper clamping part and / or the lower clamping part are provided with a plurality of clamping ends arranged in the left-right direction. The upper clamping part and the lower clamping part can approach or move away from each other;

[0008] The multi-station fixture provided on the traction saw is a sawing fixture, the multi-station fixture provided on the traction device is a traction fixture, and the multi-station fixture provided on the material handling device is a material handling fixture;

[0009] The traction device is provided with a traction drive component for driving the traction clamp to move in the front and rear directions; the traction saw is provided with a sawing translation drive component for driving the traction saw to move forward and backward; the straightening machine includes a front straightening clamp and a rear straightening clamp arranged in front and back, and the two material handling devices are both arranged between the front straightening clamp and the rear straightening clamp, and the material handling device is provided with a material handling drive component, and the material handling drive component is used to drive the material handling clamp to move between the upper side of the extrusion conveyor line and the straightening machine.

[0010] The production line for producing multiple profiles provided by the present invention has at least the following beneficial effects: a plurality of clamping ends arranged left and right can form a plurality of clamping stations between the upper clamping portion and the lower clamping portion, and respectively clamp the multiple profiles produced, thereby avoiding overlapping of the multiple profiles. When the traction saw cuts the profile, the traction clamp and the sawing clamp provided on the front side can clamp the profiles on both sides of the front and back of the sawing position. The traction clamp and the sawing clamp can clamp the two ends of the profile segment, and the two material handling clamps can clamp the two ends of the profile segment and transfer them from the extrusion conveyor line to the straightening machine, so that the front straightening clamp and the rear straightening clamp clamp the front and back ends of the multiple formed segments, thereby achieving straightening and cooling. In the production line for producing multiple profiles of the present invention, the sawing clamp cooperates with the two traction clamps to clamp the respective ends of the multiple profiles of different segments, so that the multiple profiles can always be clamped and pulled, avoiding overlapping during the traction process. The profile section uses two handling devices to synchronously grip and handle multiple profiles, allowing them to be transferred to the straightening machine in a horizontally aligned manner. From extrusion to straightening and cooling, multiple extruded profiles remain aligned and prevent overlap, significantly improving production efficiency.

[0011] As a further improvement of the above technical solution, the traction machine includes two traction rails arranged one above the other, and the traction rails extend in the front-to-back direction;

Under the drive of the lifting drive member and the translation drive member, the traction fixture can retract from the extrusion conveyor line to avoid the position of the profile; the two traction fixtures can also be staggered up and down relative to each other, so as to realize the front and back staggered movement of the two traction devices and achieve alternating traction. The extruded multiple profiles can always be clamped by at least one traction fixture, avoiding the reset waiting of the traction device and also avoiding the overlapping phenomenon of the profiles.

[0016] As a further improvement of the above technical solution, the traction fixture includes a traction upper clamp, a traction lower clamp and a traction clamp drive member.

For profiles with uneven upper side end faces, multiple juxtaposed upper clamp pliers can respectively clamp multiple positions on the upper side of the profile, so that the traction fixture can adapt to the clamping and traction of special-shaped profiles; the multiple upper clamp pliers can also avoid the mutual influence of the clamping of multiple profiles and are suitable for the extrusion traction in the form of one-out-multiple.

The first upper clamping end is eccentrically arranged with respect to the rotating end, and the first upper clamping end extends in an arc shape and is provided with raised anti-slip teeth along the edge.

[0062] The number of the upper clamping pliers 425 is plural. The rotating ends of the plural upper clamping pliers 425 are rotationally connected coaxially.

[0063] When using the traction fixture 420 of this embodiment: The lower side of the extruded profile is closely attached to the first lower clamping end. The traction clamp driving member 423 drives the traction upper clamp 421 to move downward to be close to the upper side of the profile, and the traction clamping driving member drives the clamping shaft rod 426 to rotate, releasing the jacking portions of the plural upper clamping pliers 425. The first upper clamping ends of the plural upper clamping pliers 425 swing downward under the action of gravity and abut against the upper side end face of the profile.

[0064] It should be noted that the first upper clamping end is provided on one side of the rotating end in the traction direction. When the first upper clamping end provided on one side of the traction direction turns downward and abuts against the profile, a self-locking structure can be formed with the profile. Taking the backward traction of this embodiment as an example: The first upper clamping end is provided on the rear side of the rotating end. When the first upper clamping end turns downward and abuts against the profile, the traction force of the first upper clamping end acting on the profile is set backward. The first upper clamping end receives a forward reaction force from the profile. A part of the component force of this reaction force acts on the clamping plier 425 along the connection line between the first upper clamping end and the rotating end, and the other part of the component force can promote the first upper clamping end to turn downward and press the profile, so that the clamping is kept stable.

The plural material supporting and conveying units are arranged at intervals in the front and rear directions. In this embodiment, the material supporting and conveying unit adopts a conveyor belt assembly, and the profile is conveyed by a heat-resistant conveyor belt arranged in a ring shape.

[0067] The material support conveyor device 330 is located on the left side of the extrusion conveyor line 100.

When clamping the profile through the upper material handling clamping portion and the lower material handling clamping portion, the material handling base plate 521 will not obstruct the profile.

[0079] The material handling clamping driving member 524 is used to drive the material handling upper clamp 522 and the material handling lower clamp 523 to move closer or farther away from each other in the up and down direction.

[0080] In this embodiment, the material handling clamping driving member 524 includes a lower clamp driving member and an upper clamp driving member.

[0087] When using the multi-profile production line of the present invention to produce profiles:

[0088] The extruder extrudes multiple profiles backward from the extrusion outlet. For the convenience of description, the two traction devices are respectively a first traction device and a second traction device. The traction fixture 420 of the first traction device simultaneously clamps the rear ends of the multiple profiles, and is driven by the traction drive member 440 to be pulled backward in coordination with the extrusion speed.

[0089] As the extrusion and traction proceed, when the extrusion length of the profile reaches the requirement, the second traction device simultaneously clamps the multiple profiles in front of the first traction device. The sawing fixture 240 is on the front side of the second traction device and simultaneously clamps the multiple profiles. At this time, the sawing fixture 240 and the two traction fixtures 420 move backward and are pulled at the same speed.

[0090] The sawing feed drive member drives the sawing device 250 to saw the profile between the second traction device and the sawing fixture 240 and then retracts. The sawing device 250 is arranged on the rear side of the sawing fixture 240, so that the profile is disconnected between the traction fixture 420 of the second traction device and the sawing fixture 240. After the profile sawing is completed, the sawing fixture 240 of the traction saw 200 holds the end of the extruded profile and continues to be pulled backward. The first traction device and the second traction device respectively hold the front and rear ends of the multiple profile segments and move backward until the two ends of the profile segments are respectively aligned left and right with the front straightening clamp 310 and the rear straightening clamp 320.

[0091] At this time, the material handling drive members 530 of the two material handling devices 500 drive the two material handling fixtures 520 to move to the right. The upper material handling clamping parts and the lower material handling clamping parts of the two material handling fixtures 520 are respectively arranged on the upper and lower sides of the profile segment. The lower clamping drive member and the upper clamping drive member respectively drive the material handling upper clamp 522 and the material handling lower clamp 523 to move, so that the upper material handling clamping part and the lower material handling clamping part are clamped towards each other. The multiple clamping blocks 526 respectively correspond to the multiple profiles one by one.

[0092] After the front and rear parts of multiple profile material segments are clamped by the two material handling clamps 520 respectively, the first traction device and the second traction device release the front and rear ends of the profile material segments respectively. The two traction clamps 420 also retract to the right under the drive of the traction translation drive member 470, and then move forward to clamp and traction the next profile. After the first traction device reclamps the end of the next profile, the sawing clamp 240 releases the profile. After the sawing clamp 240 releases the profile, the sawing clamp translation drive member drives the sawing clamp 240 to move to the left, avoiding the space above the extrusion conveying line 100 and waiting for the traction saw 200 of the next profile to cut.

[0093] After the first traction device and the second traction device release the front and rear ends of the profile material segment respectively, the lifting drive member 460 drives the lifting frame to move upward, causing the multiple translation conveying units to rise. The translation conveying surface rises from below the traction conveying surface, lifting the profile between the two material handling clamps 520 from the extrusion conveying line 100. Then, the material handling drive member 530 drives the material handling clamp 520 to move to the left. At the same time, the multiple translation conveying units act to convey the profile to the left, enabling the profile body to move to the left together with the two ends.

[0094] When the profile moves between the front straightening clamp 310 and the rear straightening clamp 320, the jaws of the front straightening clamp 310 and the rear straightening clamp 320 can just clamp the front and rear ends of the profile. After that, the two material handling clamps 520 release the profile, and the lifting drive member 460 also drives the lifting frame to retract downward. While the front and rear ends of the profile are clamped by the front straightening clamp 310 and the rear straightening clamp 320, the profile body is placed on the material supporting conveying device 330.

[0095] When the profile is on the translation conveying device 540 and the material supporting conveying device 330, the cold air blower can blow upward air flow to take away the heat of the profile, accelerating the cooling process of the profile. After the straightening and forming are completed by the front straightening clamp 310 and the rear straightening clamp 320, the material supporting conveying device 330 can convey multiple profiles to the left for discharging simultaneously, entering the subsequent length determination and material receiving processes.

[0096] In the one-to-multiple profile production line of this embodiment, three different multi-station clamp structures of the traction clamp 420, the sawing clamp 240 and the material handling clamp 520 are provided. In some embodiments, the clamp structures in the traction device, the traction saw 200 and the material handling device 500 can adopt any one of the above three clamp structures.

[0097] In some embodiments, the sawing fixture 240 is provided at the rear side of the sawing device 250. The two traction fixtures 420 need to perform clamping alternately. One of the traction fixtures 420 traction the extruded profile, and the other traction fixture 420 and the sawing fixture 240 clamp and convey the profile segment. After the material handling device 500 moves the profile segment, while loosening the traction fixture 420 of the profile and retracting it to the right, the lifting drive member 460 is used to drive the other traction fixture 420 to be staggered up and down, so as to move forward to the front of another traction device to prepare for the traction of the next profile segment.

[0098] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
