Description

Technical Field

[0001] This application relates to the field of steel section transfer and processing technology, and in particular to a fully automatic positioning and drilling device for long steel sections. Background Technology

[0002] Section steel is a type of steel profile with specific dimensions and mechanical properties, produced by pressure processing of steel. The forming and processing of steel often employs pressure processing techniques, causing plastic deformation of the blank. A wide variety of section steel is used in the construction industry. Steel structural components are often connected and fixed using bolts and nuts; therefore, it is necessary to pre-drill suitable bolt holes in the section steel using a drilling machine.

[0003] Currently, the overall automation level of steel section punching operations is low. Manual unstacking and feeding of steel sections into the punching machine is usually required, which not only results in low work efficiency and high labor costs, but also has problems such as insufficient docking positioning accuracy and easy to cause punching deviation. If the existing automatic feeding devices are arranged at the front and rear ends of the punching machine, the equipment occupies a large space. If a parallel layout is adopted, it is easy to cause motion interference between the longitudinal and transverse conveying mechanisms during clamping and transfer. In addition, for steel sections of different specifications and models, a compatible fully automatic feeding and conveying system is required to meet the needs of multi-variety production. Summary of the Invention

[0004] This device provides a fully automatic positioning and drilling device for long strip steel, and the specific implementation method is as follows: A fully automatic positioning and drilling device for long strip steel, comprising: A punching machine and steel profile conveyor lines located at both ends of the punching machine; The two steel conveying lines are respectively equipped with an inlet translation component and an outlet translation component, and both the inlet translation component and the outlet translation component are equipped with clamping components for positioning the ends of the long steel sections. Several hoisting supports are equidistantly arranged along the length of the steel conveying line. The hoisting supports are equipped with clamping components for clamping the periphery of long steel sections via hoisting and transfer components. Several groups of guide wheel assemblies are equidistantly arranged along the length of the steel conveyor line. Within the same group, the guide wheel assemblies are arranged in opposite directions on both sides of the steel conveyor line. The output end of the guide wheel assembly is positioned to abut against the steel conveyor line through the guide wheel.

[0005] Based on the above technical solution, by setting steel conveying lines at both ends of the punching machine, and by setting inlet and outlet translation components with clamping assemblies on the steel conveying lines, the end positioning automatic conveying of long steel sections is realized, which improves punching efficiency and punching accuracy.

[0006] Preferably, the clamping assembly includes an L-shaped mounting plate and a flipping plate that are hinged to each other, with their rear ends connected by a first cylinder, and their front ends respectively provided with a lower plug and an upper plug that are vertically positioned on the top surface of the end of the steel conveyor line.

[0007] Preferably, the steel conveying line includes an upward-opening U-shaped base, and the U-shaped base is provided with a third rack along its length; the inlet translation component and the outlet translation component have the same structure. Taking the inlet translation component as an example, the inlet translation component is slidably connected to the U-shaped base through a translation base plate, and the translation base plate is engaged with the third rack through a fourth servo motor and gears.

[0008] Preferably, the U-shaped base is provided with several connecting plates for mounting the guide wheel assembly at equal intervals along its length, and the spacing between adjacent connecting plates is less than the length of the long strip steel.

[0009] Preferably, the guide wheel assembly further includes a second cylinder, the arm of which is connected to a push plate for mounting the guide wheel, and the top height of the guide wheel is lower than the bottom height of the translation base plate.

[0010] Preferably, the hoisting and transfer assembly includes a translation seat and a lifting seat. The translation seat is slidably connected to the horizontal section of the hoisting bracket, and a first gear and rack structure and a first servo motor for driving the first gear and rack structure are provided between the two. The lifting seat is vertically slidably connected to the translation seat, and a second gear and rack structure and a second servo motor for driving the second gear and rack structure are provided between the two.

[0011] Preferably, the lifting platform and the clamping assembly are arranged vertically coaxially, and a laser probe and a proximity switch are respectively provided on both sides of the lifting platform.

[0012] Based on the above technical solution, by setting limit switches and laser probes in parallel on the clamping assembly, during the process of the clamping assembly falling and positioning the long steel strip, the laser probe is used to achieve rapid displacement in the first half of the falling process of the clamping assembly, and the limit switch completes the clamping trigger in the second half of the falling process. Under the condition of ensuring stable clamping of long steel strips, the transfer efficiency in drilling operations is further improved.

[0013] Preferably, it also includes a stacking rack arranged in parallel with the steel section conveying line, which includes a first base plate and limiting tubes distributed in a matrix, with a single long steel section being accommodated between two adjacent limiting tubes in the width direction.

[0014] Preferably, the clamping assembly includes a bidirectional cylinder and a second base plate, with side clamps slidably provided on both sides of the second base plate, and the arms of the bidirectional cylinder respectively connected to the side clamps.

[0015] Preferably, the inner side of the side clamp is provided with a rubber block that abuts against the side of the long strip steel, and the bottom of the side clamp is provided with a guide slope.

[0016] Based on the above technical solutions, the clamping component acts on the end of the long steel strip, realizing the longitudinal pushing of the long steel strip into the drilling machine after it is laterally hoisted in, as well as the subsequent longitudinal pushing out of the drilling machine and lateral hoisting out, making the entire drilling and conveying operation more efficient.

[0017] In summary, this application includes the following beneficial technical effects: 1. This invention achieves automatic end-positioning conveying of long steel sections of different lengths by setting steel section conveying lines at both ends of a punching machine, and by setting inlet and outlet translation components with clamping assemblies on the steel section conveying lines respectively, thereby improving punching efficiency and punching accuracy. 2. This invention, by arranging a limit switch and a laser probe side by side on the clamping assembly, allows the clamping assembly to quickly move during the first half of its descent to position the long steel strip, while the limit switch triggers the clamping action during the second half of the descent. This further improves the transfer efficiency in the drilling operation while ensuring stable clamping of the long steel strip. 3. The present invention has a simple structure. The clamping assembly uses a bidirectional cylinder to synchronously and in reverse control the two side clamping plates, which can adapt to the side clamping and transportation of long strip steel with different cross-sectional dimensions. 4. In this invention, the clamping component acts on the end of the long steel strip, realizing the longitudinal pushing of the long steel strip into the drilling machine after it is laterally hoisted in, as well as the subsequent longitudinal pushing out of the drilling machine and lateral hoisting out, making the entire drilling and conveying operation more efficient.

[0022] The following is in conjunction with the appendix Figure 1-19 This application will be described in further detail.

[0023] This application discloses a fully automatic positioning and drilling device for long strip steel. Example 1

The front ends of the L-shaped mounting plate 801 and the flipping plate 802 are respectively provided with a lower plug 805 and an upper plug 804 that are vertically positioned on the top surface of the end of the steel conveying line 1. In this structure, the extension and retraction of the arm of the first cylinder 803 causes the distance between the lower plug 805 and the upper plug 804 to decrease, and the inner sides of the lower plug 805 and the upper plug 804 are both set as inclined surfaces.

[0026] Combination Figure 4 The steel section conveying line 1 includes an upward-opening U-shaped base 101. The U-shaped base 101 is provided with a third rack 103 along its length direction. Both sides of the top of the U-shaped base 101 are provided with a third guide rail 102 along its length direction. The structure of the inlet translation component 7 and the outlet translation component 12 is the same, except that the installation positions of the clamping components 8 are opposite. Both clamping components 8 face the long steel section 11 after it is introduced.

[0027] Combination Figures 4 to 12 Taking the import translation component 7 as an example, the import translation component 7 is slidably connected to the third guide rail 10 through the translation base plate 701. The translation base plate 701 is meshed with the third rack 103 through the fourth servo motor 703 and the gear 702.

Example 2

[0029] Reference Figures 16 to 19Based on Embodiment 1, this embodiment discloses a fully automatic positioning and drilling device for long strip steel. It also includes several hoisting brackets 2 equidistantly arranged along the length of the steel conveying line 1 and a stacking rack 3 arranged parallel to the steel conveying line 1. The hoisting brackets 2 are equipped with clamping components 6 for clamping the periphery of the long strip steel 11 via hoisting and transfer components 5. In this structure, the lifting seat 502 and the clamping components 6 are arranged vertically and coaxially. Laser probes 13 and proximity switches 10 are respectively provided on both sides of the lifting seat 502. The proximity switch 10 is installed on the lifting seat 502 via a mounting bracket 1001, and the mounting bracket 1001 is vertically provided with a waist-shaped groove. The mounting bracket 1001 and the lifting seat 502 are connected by bolts. The installation position of the proximity switch 10 can be manually adjusted according to the model and height of the long strip steel 11.

[0030] Combination Figure 6 and Figure 19 The clamping assembly 6 includes a bidirectional cylinder 601 and a second base plate 602. Side clamping plates 603 are slidably provided on both sides of the second base plate 602. The arms of the bidirectional cylinder 601 are respectively connected to the side clamping plates 603. In this structure, a fourth guide rail 606 is provided at the bottom of the second base plate 602. Both side clamping plates 603 are slidably connected to the fourth guide rail 606. The inner side of the side clamping plate 603 is provided with rubber blocks 604 that abut against the side of the long strip steel 11. The bottom of the side clamping plate 603 is provided with a guide slope 605. When the two side clamping plates 603 act horizontally inward on the long strip steel 11, the guide slope 605 is used to lift the long strip steel 11, so that the rubber blocks 604 on both sides abut against the sides of the long strip steel 11. The guide slope 605 also has the effect of supporting the long strip steel 11.

[0031] Combination Figure 3 The hoisting and transfer assembly 5 includes a translation seat 501 and a lifting seat 502. The translation seat 501 is slidably connected to the horizontal section of the hoisting bracket 2. The horizontal section of the hoisting bracket 2 is provided with a first guide rail 201, a first rack 202 and a second guide rail 203 arranged side by side along its length. The first guide rail 201 and the second guide rail 203 are arranged in opposite directions. The translation seat 501 is slidably connected to the first guide rail 201 and the second guide rail 203. A first servo motor 503 is installed on the translation seat 501. The output end of the first servo motor 503 is meshed with the first rack 202 through a gear. A second rack 5021 is provided on the lifting seat 502. The translation seat 501 and the lifting seat 502 are vertically slidably connected. A second servo motor 504 is horizontally installed on the translation seat 501. The output end of the second servo motor 504 is meshed with the second rack 5021 through a gear.

[0032] Combination Figure 15The stacking rack 3 includes a first base plate 301 and a matrix of limiting tubes 302. A single long steel strip 11 is placed between two adjacent limiting tubes 302 in the width direction. In this structure, the long steel strips 11 adjacent in the horizontal direction are separated by the limiting tubes 302, and the long steel strips 11 are stacked together in the vertical direction. The limiting tubes 302 and the clamping assembly 6 are staggered.

[0033] The specific implementation process is as follows: Long strip steel 11 is stacked on the palletizing rack 3, and the hoisting and transfer component 5 controls the clamping component 6 to move on the hoisting bracket 2; the laser probe 13 detects the long strip steel 11 on the palletizing rack 3, the second servo motor 504 starts to control the lifting seat 502 to fall at high speed, and suspends the clamping component 6 directly above the top long strip steel 11, with the distance between the two being a preset value; then the proximity switch 10 is connected, the second servo motor 504 starts to control the lifting seat 502 to fall at low speed, and the proximity switch 10 abuts against the long strip steel 11 and triggers the clamping component 6 to clamp; During the clamping process, the bidirectional cylinder 601 retracts its arm, and the side clamps 603 on both sides move inward synchronously. The guide slope 605 abuts against the long steel strip 11 and raises it. Then, the rubber blocks 604 on both sides abut against the sides of the long steel strip 11. The second servo motor 504 reverses at high speed, and each clamping assembly 6 controls the long steel strip 11 to be lifted and transported away from the stacking frame 3. The first servo motor 503 controls the lifting seat 502, the clamping assembly 6 and the long steel strip 11 to move horizontally along the length of the lifting bracket 2. Once the long steel section 11 is fed into the upper part of the steel section conveyor line 1, the second servo motor 504 controls the lifting seat 502, the clamping assembly 6 and the long steel section 11 to fall; the second cylinder 901 arms of each guide wheel assembly 9 extend, and each guide wheel 903 abuts and is positioned on both sides of the long steel section 11. The import translation component 7 moves along the direction of the steel section conveyor line 1, the clamping component 8 clamps the end of the long steel section 11, and the hoisting and transfer component 5 and the clamping component 6 are reset. The import translation component 7 pushes one end of the long steel section 11 with the help of the clamping component 8 and sends it into the punching machine 4. The export translation component 12 on the other side clamps the other end of the long steel section 11 through the clamping component 8, realizing the automatic conveying of the long steel section 11 together. After the punching is completed, the export translation component 12 transports the long steel section 11 into the steel section conveyor line 1 on the other side through the clamping component 8. The hoisting and transfer component and the clamping component on the other side put the punched long steel section 11 into a new stacking rack 3 for stacking, thus completing the fully automatic conveying and punching operation of a single long steel section 11.
