Description

Technical Field

[0001] This invention belongs to the field of aerospace profile production in the aluminum processing industry, and particularly relates to a roller measuring and loading / unloading device for a roller straightening machine and its usage method. Background Technology

[0002] Extruded profiles for aerospace applications are mainly made of 2XXX and 7XXX aluminum alloys, both of which are precipitation-strengthened aluminum alloys. They typically undergo solution hardening heat treatment before use. The varying surface tensions generated during the hardening process cause bending and warping of the extruded profiles, requiring subsequent straightening using a straightening machine.

[0003] The straightener roller is a ring-shaped component located on the round roller of the roller straightener. The round roller has a raised structure, and the inner ring of the roller has a groove. During use, it is connected by tenon and mortise. The round roller and the roller rotate synchronously during the profile straightening process.

[0004] Extruded profiles come in a wide variety of cross-sections, such as "J", "T", "L", "Z", and "H", and even the same cross-section can have different dimensions. Therefore, frequent roller replacements are necessary in actual production. Currently, the roller replacement process involves manually removing the roller, measuring and selecting a matching roller, and then manually assembling it. At present, the rollers on roll straightening machines weigh 30kg to 50kg and are installed at a height of 1.5m to 2m. This creates difficulties in roller measurement and replacement, resulting in wasted manpower and resources, as well as waiting time for subsequent processing. It also increases production costs and disrupts production continuity. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this invention designs and manufactures an automatic roller measurement and loading / unloading device. This design fully considers the convenience, safety and versatility of the tooling. It can be used with existing cantilever cranes to realize the measurement and loading / unloading of rollers. The tooling is not only simple to manufacture, but can also be operated by a single person, which greatly reduces the production cost.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides a roller measuring and loading / unloading device for a roller straightening machine, comprising: a support member, a base, a slider, a mounting bracket, a laser measuring instrument, and a telescopic claw. The base is mounted on the bottom of the support member, and the surface of the base is provided with multiple grooves. The slider is installed in the grooves and is used to install the roller. The slider is used to cooperate with the roller. Two symmetrical mounting brackets are provided on both sides of the support member. The two mounting brackets are provided with a laser measuring instrument and a telescopic claw. The laser measuring instrument is used to measure the diameter of the roller, and the telescopic claw is used to cooperate with the base to fix the roller.

[0008] Furthermore, a pull ring parallel to the structure is installed on the upper side of the supporting square tube, which is connected by welding. Its function is to connect the loading and unloading structure with the cantilever crane.

[0009] Furthermore, the supporting component is welded from four U-shaped steel bars to form a rectangular frame platform.

[0010] Furthermore, the slider and telescopic claw are provided with pads.

[0011] Furthermore, the card holder has a U-shaped structure and is fitted onto the vertical beam of the supporting component.

[0012] Furthermore, the telescopic claw is perpendicular to the support platform.

[0013] Secondly, the present invention employs a method for using a measuring and loading / unloading device for a roller straightener as described in the first aspect, comprising the following steps:

[0014] Use a cantilever crane to vertically suspend the support components at the same height as the rollers of the straightener;

[0015] Place the roller on the base of the support component and use a laser measuring instrument to measure the diameter of the roller;

[0016] Adjust the dimensions of the base and telescopic claw according to the diameter value to match the roller size;

[0017] The rollers are fixed by the base of the supporting components and the telescopic claws;

[0018] The rollers are removed from the straightening machine using a cantilever crane.

[0019] The beneficial effects of this invention are:

[0020] 1. This invention has strong versatility. The base can adjust the slider according to the shape of the roller, so that the groove of the base matches the roller. The card seat can be raised and lowered according to the diameter of the roller. The telescopic claw can move back and forth according to the thickness of the roller. The base and card seat work together to be suitable for the transportation and loading and unloading of rollers of different specifications, so as to achieve the purpose of reducing costs and increasing efficiency. At the same time, the ring above the support platform corresponds to the cantilever crane, which effectively shortens the hoisting time and improves the work efficiency.

[0021] 2. The support platform of this invention uses square tube steel material, which reduces the weight of the invention itself, makes it convenient for single-person use, reduces the work done by the cantilever crane, and reduces production costs.

[0022] 3. This invention boasts high safety performance. The entire support platform is integrated using welding, and the steel structure ensures load-bearing strength. The support components and lifting seats define the roller positions. During use, personnel can independently transport and unload the rollers from one side.

[0023] 4. This invention has high utilization rate, simple structure, and is easy to carry. Adults can transport it with one hand. The rectangular structure occupies little space and can be stored upright after use, thus increasing the activity space.

[0024] 5. The present invention is low in cost, simple in structure, and low in manufacturing cost, which greatly saves cost investment.

[0025] Advantages of additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0035] Example 1

[0036] like Figures 1-2 As shown, this invention provides a roller measuring and loading / unloading device for a roller straightening machine, including a support component 1, a base 2, a slider 3, a mounting bracket 4, a laser measuring instrument 5, and a telescopic claw 6. The support component 1 is welded from four U-shaped steel bars to form a rectangular frame platform. The base 2 is installed at the bottom of the support component 1. The surface of the base 2 has multiple evenly distributed grooves, and the slider 3 is installed in the grooves. The slider 3 is used to install the roller and can be inserted into the groove. The slider 3 can be adjusted to fit various grooves to match rollers of different sizes and shapes. Two symmetrical mounting brackets 4 are set on both sides of the support component 1. The laser measuring instrument 5 and the telescopic claw 6 are installed on the two mounting brackets 4. The laser measuring instrument 5 is used to measure the diameter of the roller, and the telescopic claw 6 is used to fix the roller with the base 2 to ensure that the roller remains stationary during transportation. The mounting brackets 4 can move up and down on both sides of the support component and can be adjusted according to the size of the roller. A pull ring 7 parallel to the structure is set on the upper side of the square tube of the support component 1 and connected by welding. Its function is to connect the loading / unloading structure to the cantilever crane.

[0037] The slider 3 and the telescopic claw 6 are equipped with pads, which can increase the friction force between the device and the roller, keep the roller stable, and protect the roller from scratches.

[0038] The card holder 4 is a lifting card holder 4, which is connected to the support member 1 by a collar. The card holder 4 has a U-shaped structure and fits onto the vertical beam of the support member 1, allowing it to move up and down on both sides of the support member 1. The card holder 4 and the base 2 cooperate with each other to transport and load / unload rollers of different diameters.

[0039] The base 2 is fixed to the crossbeam below the support member 1 by welding. The base 2 has evenly distributed sliders 3. The support member provides load-bearing capacity to meet the transportation and loading / unloading of the rollers. The sliders 3 are equipped with gaskets and are easy to install to prevent the rollers from being scratched. The sliders 3 also provide a certain amount of friction to prevent the rollers from slipping.

[0040] The telescopic claw 6 is perpendicular to the support platform and can move back and forth on the card holder 4. The telescopic claw 6 can grab the roller and has a fixing function. In this way, through the cooperation of the lifting card holder 4, the telescopic claw 6 and the base 2, all rollers of the roller straightener can be transported and unloaded.

[0041] The pull ring 7 is welded to the support member 1. The pull ring 7 has a strong load-bearing capacity, improving safety during use. The pull ring 7 can be used in conjunction with a cantilever crane for the transportation and loading / unloading of rollers.

[0042] The base 2 can adjust the slider 3 according to the shape of the roller, so that the groove of the base 2 matches the roller. The clamp 4 can be raised and lowered according to the diameter of the roller. The telescopic claw 6 can move back and forth according to the thickness of the roller. The base 2 and the clamp 4 work together to transport and unload rollers of different specifications, achieving the purpose of reducing costs and increasing efficiency. At the same time, the pull ring 7 above the support platform corresponds to the cantilever crane, effectively shortening the hoisting time and improving the work efficiency.

[0043] The support platform uses square tubular steel, reducing the weight of the invention, facilitating single-person use, reducing the workload of the cantilever crane, and lowering production costs. The entire support platform is integrated using welding, and the steel structure ensures load-bearing strength. The base 2 and lifting seat 4 define the roller positions. During use, personnel can independently transport and unload the rollers while standing on one side.

[0044] Example 2

[0045] This embodiment provides a method for using the measuring and loading / unloading device of a roller straightening machine, including the following steps:

[0046] Use a cantilever crane to vertically suspend the support component 1 at the same height as the straightener rollers;

[0047] The roller is placed on the base 2 of the support member 1, and the diameter of the roller is measured using a laser measuring instrument 5.

[0048] Adjust the dimensions of the base 2 and telescopic claw 6 according to the diameter value to match the roller size;

[0049] The roller is fixed by the base 2 and telescopic claw 6 of the support component 1;

[0050] The rollers are removed from the straightening machine using a cantilever crane.

[0051] Specifically:

[0052] 1. Remove the roller from the straightener; install support component 1, and use a cantilever crane to vertically suspend support component 1 at the same height as the straightener roller, for example, at a height of 1.5m. Move support component 1 to place the roller on the base 2 of support component 1. Move the clamp 4; the laser measuring instrument 5 on the clamp 4 can accurately measure the diameter of the roller. Based on the measured value, move the clamp 4 up and down, and simultaneously adjust the telescopic claw 6 to hold the straightener roller. Remove the roller from the straightener using the cantilever crane.

[0053] 2. Select matching rollers according to the profile to be straightened; select rollers of appropriate diameter by laser measurement on support member 1. As one implementation method, three rollers of Φ290mmx30mm, Φ380mmx20mm and Φ290mmx30mm can be selected.

[0054] 3. Install the rollers, suspending the support member 1 at the same height as the roller storage. Move the support member 1 to place the rollers on the base 2 of the support member 1. According to the measured values, move the clamp 4 up and down, while adjusting the telescopic claw 6 to hold the straightener rollers. Use a cantilever crane to lift the rollers, and use the cantilever crane to move the support member 1 to install the rollers on the straightener.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
