Description

Technical Field

[0001] The present invention relates to a method for producing, transporting and surface-treating rectangular workpieces. Background Art

[0002] The internal partition plate of a steel structure box column is an important component of the box column, which has an important impact on the mechanical properties of the steel structure column. The quality of the internal partition plate often affects the mechanical properties of the column itself and thus affects the safety of the entire building.

[0003] Before assembly, the electroslag strip needs to be polished to remove the surface cutting slag. The electroslag strip is in the shape of a slender rectangular strip. Workers need to polish the edges of the electroslag strip smoothly, and the consumption is extremely large. The use of manual methods is economically poor, and it is extremely easy for workers to hold the polishing tools to cause danger, which cannot meet the requirements of the automated production line of electroslag strips. Summary of the Invention

[0004] The purpose of the present invention is to provide a technical solution for a method for producing, transporting and surface-treating rectangular workpieces in view of the deficiencies of the prior art. The steps of the transporting and surface-treating method are simple. It can not only realize the automated transportation and processing of electroslag strips, but also effectively remove the slag hanging on the surface of the electroslag strips, strengthen the surface strength of the electroslag strips, and meet the requirements of production line processing.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A method for producing, transporting and surface-treating rectangular workpieces, characterized by including the following steps:

[0007] S1. First, cut the two side edges of the finished steel plate to remove the oxide layer and ensure that the cut steel plate does not deform;

[0008] S2. Then transfer the cut steel plate to the laser cutting mechanism, perform laser cutting on the steel plate to form electroslag strips, and then sort the electroslag strips through the electroslag strip sorting mechanism, and intermittently turn and convey them to the electroslag strip transporting mechanism;

[0009] S3. The electroslag strips are intermittently moved to the surface treatment mechanism through the electroslag strip transporting mechanism. A transporting trolley is movably connected to the surface treatment mechanism. The transporting trolley receives the electroslag strips, and the transporting trolley carries the electroslag strips and horizontally moves along the track on the first frame. When moving to the position of the particle spraying device, metal particles are sprayed onto the surface of the electroslag strips through the particle spraying device to remove the cutting slag on the surface of the electroslag strips and perform strengthening treatment on the electroslag strips;

[0010] S4. Then the transporting trolley drives the treated electroslag strips to move along the track to the lifting transfer mechanism, and the electroslag strips are transferred to the stepping mechanism through the lifting transfer mechanism;

[0011] S5. Finally, the electro-slag bars are arranged and lifted in sequence by the stepping mechanism, and move forward in turn and are finally picked up by the robot, realizing the automated processing and transfer of the electro-slag bars.

[0012] This transfer and surface treatment method has simple steps. It can not only realize the automated transfer and processing of electro-slag bars, but also effectively remove the slag adhering to the surface of the electro-slag bars, strengthen the surface strength of the electro-slag bars, and meet the requirements of assembly line processing.

[0013] Furthermore, the laser blanking mechanism includes a laser blanking table and a laser head. The laser head is located above the laser blanking table, and the laser head is connected to a laser cutting machine.

The vibrator and the flipping mechanism are arranged on the discharging side of the electro-slag bar sorting and arranging table. The flipping mechanism is controlled by a stepping motor to achieve a 90° flip. During the waiting period, the flipping brackets close to the electro-slag bar sliding ramp are flush with the electro-slag bar sliding ramp to ensure that the electro-slag bars slide into the flipping brackets correctly. The electro-slag bars are sorted and slide down through the electro-slag bar sliding ramp on the electro-slag bar sorting and arranging table, and the electro-slag bars can be transferred to the electro-slag bar transfer mechanism through the flipping mechanism.

The third motor controls the rotation action of the rotary clamping head. A pair of rotary clamping heads clamp the electroslag bar. When passing through the particle spraying device, the third motor starts to drive the electroslag bar to rotate, so that the surface of the electroslag bar can be impacted by the particles, thereby achieving the technical effects of removing the surface cutting slag and strengthening the surface. The protective cover can play a protective role.

[0018] Furthermore, the particle spraying device includes a housing, a feed pipe, a first motor, and a rotary projection assembly.

The second rotating seat passes through the positioning blocks through a connecting shaft and is limited in the waist-shaped hole and moves along the waist-shaped hole; the cylinder drives the support table surface to reciprocate along the second slide rail through the piston rod, and then pushes the connecting rod to move along the waist-shaped hole. The descending height of the stepping table surface is the vertical projection of the moving distance of the connecting rod along the waist-shaped hole. The horizontal moving distance of the stepping table surface is the horizontal projection of the moving distance of the connecting rod along the waist-shaped hole, that is, each step is the distance of an adjacent groove.

A transfer trolley 8 is movably connected to the surface treatment mechanism 4. The transfer trolley 8 receives the electroslag bar and carries the electroslag bar to move horizontally along the track 402 on the first frame 401. When it moves to the position of the particle spraying device 5, metal particles are sprayed by the particle spraying device 5 onto the surface of the electroslag bar to remove the cutting slag on the surface of the electroslag bar and perform strengthening treatment on the electroslag bar.

[0068] A fourth motor 403 and a first driven wheel 405 are provided on the track 402. The output shaft of the fourth motor 403 is connected with a first driving wheel 404. The first driving wheel 404 is connected with the first driven wheel 405 through a first belt 406. The transfer trolley 8 is connected to the first belt 406. By driving the first driving wheel 404 to rotate through the fourth motor 403, the first driven wheel 405 can be driven to rotate through the first belt 406, so that the first belt 406 drives the transfer trolley 8 to move along the track 402, realizing the transportation of the electroslag bar.

The particles flow out from the first through groove 508 between the connecting blocks 507 and enter the housing 501 through the second through groove 511 of the outer retaining ring 509, and are sprayed out under the action of the fan blades 510.

[0072] The top of the particle spraying device 5 is connected to a cross beam 9 through a mounting plate 10.

[0073] S4. Then, the transfer cart 8 drives the processed electroslag bar to move along the track 402 to the lifting and transfer mechanism 6, and the electroslag bar is transferred to the stepping mechanism 7 through the lifting and transfer mechanism 6;

[0074] The lifting and transfer mechanism 6 includes a cantilever 61, a sliding seat 62, and a bracket 63. A fifth motor 6301 and a second driven wheel 6303 are provided on the bracket 63. A second driving wheel 6302 is connected to the output shaft of the fifth motor 6301. The second driving wheel 6302 is connected to the second driven wheel 6303 through a second belt 6304. A second guide rod 6305 and a buffer seat 6306 are provided on the bracket 63.

[0075] The sliding seat 62 is connected to the second guide rod 6305 and the second belt 6304. The sliding seat 62 includes side plates 6201, limit blocks 6203, sliding wheels 6204, and boosting blocks 6205. The two side plates 6201 are fixedly connected by a connecting column 6202. The limit blocks 6203 are arranged on the inner side surfaces of the side plates 6201. The limit blocks 6203 are slidably connected to the second guide rod 6305. The sliding wheels 6204 are connected to the two side plates 6201. The sliding wheels 6204 abut against the second guide rod 6305.

[0076] The fixed block 6207 is connected to the cantilever 61 through a connecting component 6208. There are two wall panels 6101 on the cantilever 61. A cavity 6102 is formed by the cooperation between the wall panels 6101 and the cantilever 61. Slots 6103 are symmetrically arranged at the bottoms of the wall panels 6101. A spoon-shaped component 6104 is rotatably connected in the slots 6103. The spoon-shaped component 6104 is provided with a tip 6106 and an inclined surface 6107. A swing rod 6105 is arranged on the outer side surface of the spoon-shaped component 6104. A pendant 6108 is rotatably connected to the swing rod 6105. A fixed shaft is arranged in the slot 6103. The fixed shaft is connected to the spoon-shaped component 6104 through an elastic element; Through the lifting and transfer mechanism 6, the electroslag strip can be transferred from the surface treatment to the stepping mechanism 7, so that the processes are effectively connected, and a fully automated electroslag strip grinding production process is realized.

[0077] During the process of the lifting and transfer mechanism 6 swallowing the electroslag strip, the electroslag strip is clamped by the transfer trolley 8 at this time. The lifting and transfer mechanism 6 moves downward. When the tip 6106 of the spoon-shaped component 6104 abuts against the electroslag strip, it rotates around the rotation axis. The tip 6106 of the spoon-shaped component 6104 withdraws from the cavity 6102. When the electroslag strip passes through, the rotation axis is pulled back, and the tip 6106 of the spoon-shaped component 6104 returns to the cavity 6102 again and plays a blocking effect on the electroslag strip.

[0078] When the lifting and transfer mechanism 6 continues to descend, when the pendant 6108 contacts the lower stepping mechanism 7, the pendant 6108 contacts the protrusions on both sides, drives the spoon-shaped component 6104 to rotate, the tip 6106 retracts, and the electroslag strip falls into the groove 706.

[0079] The stepping mechanism 7 includes a second frame body 701, a second base 708, a fixed tabletop 704, a support tabletop 707, and a stepping tabletop 705. The second base 708 is provided at the bottom of the second frame body 701, and the fixed tabletop 704 is provided at the top of the second frame body 701. A cylinder 709 and a second slide rail 711 are provided on the second base 708. The cylinder 709 is connected to the support tabletop 707 through a piston rod 710. The support tabletop 707 is connected to the second slide rail 711 through a second slider 712. A first rotating seat 713 is provided on the support tabletop 707. The first rotating seat 713 is connected to a second rotating seat 715 through a connecting rod 714. Positioning blocks 716 are symmetrically provided on both sides of the second rotating seat 715. The positioning blocks 716 are connected to the stepping tabletop 705 through support members 717. The stepping tabletop 705 is located between two fixed tabletops 704. Grooves 706 are evenly provided on the stepping tabletop 705 and the fixed tabletops 704. A waist-shaped hole 702 is provided on the side surface of the second frame body 701. The second rotating seat 715 passes through the positioning blocks 716 through a connecting shaft 703 and is limited in the waist-shaped hole 702 and moves along the waist-shaped hole 702. The support tabletop 707 is driven by the cylinder 709 through the piston rod 710 to make a reciprocating movement along the second slide rail 711, and then the connecting rod 714 is pushed to move along the waist-shaped hole 702. The descending height of the stepping tabletop 705 is the vertical projection of the moving distance of the connecting rod 714 along the waist-shaped hole 702, and the horizontal moving distance of the stepping tabletop 705 is the horizontal projection of the moving distance of the connecting rod 714 along the waist-shaped hole 702, that is, each step is the distance of an adjacent groove 706. The first rotating seat 713, the second rotating seat 715, the positioning blocks 716, and the support members 717 improve the stability and reliability of the stepping tabletop 705 during movement. The grooves 706 facilitate the stepping transportation of the processed electroslag bars.

[0080] There are grooves 706 on the stepping tabletop 705. When the rotating shaft moves from point C to point D, its horizontal component is the horizontal distance from point C to point D of the groove 706, and its vertical component is the vertical distance from point C to point D. Those skilled in the art can design the stepping mechanism 7 at different angles according to their own situations.

[0081] The grooves 706 on the stepping tabletop 705 are arranged in sequence to lift the electroslag bars forward in turn and are finally picked up by the robot, realizing the automatic processing and transfer of the electroslag bars.

[0082] S5. Finally, the stepping mechanism 7 arranges and lifts the electroslag bars in sequence, moves forward in turn and is finally picked up by the robot, realizing the automatic processing and transfer of the electroslag bars.

[0083] The steps of the transfer and surface treatment method are simple. It can not only realize the automatic transfer and processing of the electroslag bars, but also effectively remove the slag hanging on the surface of the electroslag bars, strengthen the surface strength of the electroslag bars, and meet the requirements of pipeline processing.

[0084] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to achieve substantially the same technical effects are all covered by the protection scope of the present invention.
