Description

Technical Field

[0001] The present invention belongs to the technical field of steel skeleton forming and grinding equipment, and discloses a light roof panel steel skeleton forming and grinding equipment and a method thereof. Background Art

[0002] The basic structure of the steel skeleton light wall panel mainly consists of a square steel skeleton, a lightweight core material and a panel. Among them, the square steel skeleton is the main load-bearing structure of the wall, which is made by bending and welding cold-formed thin-walled steel plates, and has excellent seismic performance and load-bearing performance. The lightweight core material is filled inside the steel skeleton, usually made of materials such as lightweight concrete, and has properties such as sound insulation, heat insulation and fire protection; and the square steel skeleton of the light roof panel needs to be polished during the production process to produce high-quality border profiles that meet the design requirements.

[0003] The Chinese utility model patent with the patent application number: CN202223310955.6 discloses a polishing device for metal skeletons, including a processing table. Four electric telescopic rods are fixedly connected to the top of the processing table. An installation return plate is fixedly connected between the four electric telescopic rods. An installation slider is slidably connected inside the installation return plate. A polishing assembly is connected to the bottom of the installation slider. A driving assembly is connected to the front of the installation return plate. Two symmetrically arranged moving grooves are opened on the top of the processing table. A moving slider is slidably connected inside the moving groove.

[0004] The above-mentioned existing grinding and polishing equipment uses a polishing wheel to perform grinding and polishing operations on the formed steel skeleton to ensure that the surface of the steel skeleton is smooth and delicate. The entire equipment is equipped with an automatic control system, which can set parameters according to different specifications to realize grinding and polishing operations on steel skeletons of different specifications.

[0005] However, the use effect of the above-mentioned existing grinding and polishing equipment is relatively poor. During a single clamping process, only one-sided grinding and polishing operations can be performed on the steel skeleton. When multiple sides of the steel skeleton need to be ground and polished, multiple clamping operations need to be performed on the steel skeleton, which reduces the use effect. And the above-mentioned existing grinding and polishing equipment realizes the grinding operation on the steel skeleton by the downward movement and rotation of the polishing wheel. During the clamping and grinding operations, due to the clamping error and the distance error of each downward movement, it is easy to make the polishing effects of each side of the steel skeleton difficult to be consistent, reducing the use effect, and the production accuracy, production quality and production efficiency are low. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a forming and grinding device and method for the steel skeleton of a light roof panel, which is used to solve the problem that the existing grinding device can only grind one side surface at a time during one clamping, and due to clamping errors and grinding errors, it is difficult to ensure the same polishing effect on each side surface of the steel skeleton, and it is impossible to perform high-precision and high-efficiency full grinding and polishing on the steel skeleton, thereby reducing the use effect.

[0012] Further optimization: The rolling type workpiece feeding mechanism includes a roller frame which is arranged in parallel below the lower connecting beam. Steel rollers are rotatably installed on the roller frame. At least one Z-axis automatic telescopic rod is fixedly installed on the upper surface of the lower connecting beam. The telescopic end of the Z-axis automatic telescopic rod is arranged vertically downward and fixedly connected with the roller frame.

[0013] Further optimization: The lifting type upper grinding assembly includes columns fixed at the left and right positions inside the housing frame.

At this time, one end of the square opening steel skeleton needs to pass through the middle of the housing frame and be clamped by the automatic claw of the progressive moving assembly. S102: Start the double-position sand belt grinding assembly, the lower polishing assembly and the lifting type upper grinding assembly to work through the control panel. The double-position sand belt grinding assembly is used to grind and polish one outer wall surface of the square opening steel skeleton. Then adjust the positions of the lifting type upper grinding assembly and the lower polishing assembly to grind and polish the top surface and the bottom surface of the square opening steel skeleton together.

In the present invention, when the progressive movement assembly works, it can clamp one end of the square-mouth steel skeleton and drive the square-mouth steel skeleton to move reciprocally. At this time, through the cooperation of the double-position sand belt grinding assembly, the lower polishing assembly, and the lifting upper grinding assembly, grinding and polishing operations can be carried out on different side walls of the square-mouth steel skeleton; thus, it can realize synchronous grinding and polishing operations on multiple sides of the square-mouth steel skeleton during one clamping and the movement of the square-mouth steel skeleton, improve the grinding and polishing effect and production rate, ensure uniform surface finish, and reduce the inconsistency caused by manual operation.

[0018] 2. In the present invention, the lower polishing assembly and the lifting upper grinding assembly respectively carry out grinding and polishing operations on the bottom surface and the top surface of the square-mouth steel skeleton to ensure that each side can be fully and evenly processed, with multi-side synchronous and continuous processing, reducing the number of clamping times and adjustment errors, and ensuring the stability and consistency of the polishing effect.

[0019] 3. In the present invention, the clamping and moving methods of the progressive movement assembly can realize stable clamping and moving operations on the square-mouth steel skeleton, avoid displacement or deformation during the polishing process, ensure that each side can be polished at a predetermined angle and position.

Specific embodiments

[0024] Embodiment 1: As Figures 1-8As shown in the figure, a forming and grinding device for the steel skeleton of a light roof panel includes a housing frame 1. A convex-character workpiece table 2 is fixedly installed at the front side position of the housing frame 1. The vertical central reference plane of the convex-character workpiece table 2 coincides with the vertical central reference plane of the housing frame 1. Double-position abrasive belt grinding assemblies 3 are arranged on both sides of the convex-character workpiece table 2 on the housing frame 1. Vertical Z-axis lifting units 4 are installed at the left and right positions inside the housing frame 1. The top ends of the telescopic ends of the two Z-axis lifting units 4 are fixedly installed with a lower connecting beam 5. A rolling feeding mechanism 6 is installed on the back of the lower connecting beam 5. A lifting upper grinding assembly 7 is arranged above the lower connecting beam 5 on the housing frame 1. A lower polishing assembly 10 is installed inside the housing frame 1. A progressive moving assembly 8 for pulling a square-section steel skeleton under the lifting upper grinding assembly 7 and moving it in the Y-axis direction is installed on the back of the housing frame 1.

[0025] In Embodiment 1, stepped portions are respectively arranged on the outer walls on both sides of the convex-character workpiece table 2, and the two stepped portions are used for placing the square-section steel skeleton to be ground and polished.

[0026] In Embodiment 1, the Z-axis lifting unit 4 adopts one of a hydraulic cylinder, a telescopic cylinder, and an electric telescopic rod. When the Z-axis lifting unit 4 works, its telescopic end extends or retracts to drive the lower connecting beam 5 to move up and down. When the lower connecting beam 5 moves up and down, it drives the rolling feeding mechanism 6 to move up and down, which is convenient for use.

[0027] As Figure 5 shown in the figure, the progressive moving assembly 8 includes a U-shaped frame 801 fixed to the back of the housing frame 1. Two symmetrically arranged sliding seats 802 are slidably installed inside the U-shaped frame 801. A support arm 804 is slidably installed on the sliding seat 802. The support arm 804 is arranged in the Y-axis direction. An automatic clamping jaw 806 is installed on one side of the support arm 804 close to the discharge end of the rolling feeding mechanism 6. The other end of the support arm 804 is arranged towards the double-position abrasive belt grinding assembly 3.

[0028] In Embodiment 1, the two sliding seats 802 move towards each other or away from each other to adjust the distance between the two support arms 804, thereby realizing the adjustment of the position of the automatic clamping jaw 806 in the X-axis direction, which is convenient for use; the support arm 804 slides on the sliding seat 802 to adjust the position of the automatic clamping jaw 806 in the Y-axis direction.

[0029] In the present Embodiment 1, the automatic gripper 806 adopts one of a mechanical automatic gripper or a pneumatic gripper. The automatic gripper 806 has two working states, namely an open working state and a clamping working state. When the automatic gripper 806 is in the open working state, the clamping part of the automatic gripper 806 is separated from the square steel skeleton. At this time, the square steel skeleton can be removed from the automatic gripper 806. When the automatic gripper 806 is in the clamping working state, the clamping part of the automatic gripper 806 is used to clamp the end of the square steel skeleton, which is convenient for use.

[0030] At positions near the upper and lower inner surfaces inside the loop-shaped frame 801, guide columns 807 for guiding the sliding of the sliding seat 802 are fixedly installed. The guide columns 807 are arranged along the moving direction of the sliding seat 802, and the sliding seat 802 is slidably connected to the guide columns 807. The sliding seat 802 can slide on the guide columns 807, improving the stability of the sliding seat 802 during movement.

[0031] X-axis automatic telescopic rods 803 are installed on the left and right outer walls of the loop-shaped frame 801. The telescopic ends of the two X-axis automatic telescopic rods 803 are arranged in a direction approaching each other, and the telescopic ends of the two X-axis automatic telescopic rods 803 penetrate the outer wall of the loop-shaped frame 801 and are fixedly connected to the outer wall of the corresponding sliding seat 802.

[0032] When the X-axis automatic telescopic rod 803 works to extend or retract its telescopic end, the telescopic end of the X-axis automatic telescopic rod 803 can drive the sliding seat 802 to move inside the loop-shaped frame 801, realizing the adjustment of the position of the sliding seat 802 in the X-axis direction.

[0033] In the present Embodiment 1, the X-axis automatic telescopic rod 803 adopts one of a hydraulic cylinder, a telescopic cylinder, or an electric telescopic rod.

[0034] A Y-axis automatic telescopic rod 805 for driving the support arm 804 to move in the Y-axis direction is fixedly installed on the sliding seat 802. The main body part of the Y-axis automatic telescopic rod 805 is arranged towards the direction of the double-position abrasive belt grinding assembly 3, and the telescopic end of the Y-axis automatic telescopic rod 805 is fixedly connected to the support arm 804.

[0035] When the Y-axis automatic telescopic rod 805 works to extend or retract its telescopic end, the telescopic end of the Y-axis automatic telescopic rod 805 can drive the support arm 804 to move on the sliding seat 802, realizing the adjustment of the position of the automatic gripper 806 in the Y-axis direction.

[0036] In the present Embodiment 1, the Y-axis automatic telescopic rod 805 adopts one of a hydraulic cylinder, a telescopic cylinder, or an electric telescopic rod.

[0037] With such a design, the working principle of the progressive movement assembly 8 is as follows: The staff places the square steel frame on the stepped part on the outer wall of the convex workpiece table 2, and then passes the square steel frame through the middle of the housing 1 until the end of the square steel frame is located between the two clamping parts of the automatic gripper 806. Then, the automatic gripper 806 is activated to clamp the end of the square steel frame, so as to achieve the purpose of stabilizing the square steel frame and ensure that there is no deviation or vibration during the processing, which is convenient for use.

[0038] Before the automatic gripper 806 clamps the square steel frame, the staff can push the sliding seat 802 to move in the X-axis direction through the X-axis automatic telescopic rod 803. The movement of the sliding seat 802 drives the automatic gripper 806 to move in the X-axis direction through the support arm 804, realizing the adjustment of the position of the automatic gripper 806, which is convenient for use.

[0039] After the automatic gripper 806 clamps the end of the square steel frame, the Y-axis automatic telescopic rod 805 is activated to push the support arm 804 to drive the automatic gripper 806 to move reciprocally. At this time, the automatic gripper 806 drives the square steel frame to move reciprocally on the lower polishing assembly 10, the lifting upper grinding assembly 7 and the double-position sand belt grinding assembly 3, so that the square steel frame is polished during the continuous movement process. Furthermore, it can avoid the seam defects during traditional continuous processing production, and ensure the consistency of the surface texture direction after polishing through the linear movement track. When three sides of the square steel frame are polished, the profile only needs to be horizontally rotated to process the remaining side without re-calibrating the reference plane.

[0044] A bidirectional lead screw electric module 302 is fixedly installed on the inner bottom surface of the auxiliary frame 301. Two moving ends of the bidirectional lead screw electric module 302 are respectively fixedly connected to the corresponding frames 303. The bidirectional lead screw electric module 302 operates to drive the two frames 303 to move respectively in the direction of approaching or departing from the convex-character workpiece table 2.

[0045] The bidirectional lead screw electric module 302 includes a bidirectional lead screw. Two symmetrically arranged thread segments are provided on the bidirectional lead screw, and the thread directions of the two thread segments are opposite. Thread blocks are respectively threadedly connected to the two thread segments, and the two thread blocks are respectively fixedly connected to the corresponding frames 303. One end of the bidirectional lead screw is drivingly connected to a displacement driving motor, and the displacement driving motor is fixedly installed on the auxiliary frame 301.

[0046] With such a design, the working process of the double-position belt sanding assembly 3 is as follows: First, start the bidirectional lead screw electric module 302 to operate. The bidirectional lead screw electric module 302 can drive the two frames 303 to move in the X-axis direction towards each other or away from each other through the two moving ends. At this time, the frame 303 can drive the belt sander 304 to move in the direction of approaching or departing from the stepped portion of the convex-character workpiece table 2 until the belt sander 304 contacts the outer wall surface of one side of the square steel skeleton. The belt sander 304 operates to remove defects, burrs and oxide layers on the outer surface of the square steel skeleton and improve the surface quality.

[0047] The rolling type workpiece feeding mechanism 6 includes a roller frame 602. The roller frame 602 is arranged in parallel below the lower connecting beam 5.

[0048] At least one Z-axis automatic telescopic rod 601 is fixedly installed on the upper surface of the lower connecting beam 5. The telescopic end of the Z-axis automatic telescopic rod 601 is vertically downward and fixedly connected to the roller frame 602. The Z-axis automatic telescopic rod 601 operates to drive the roller frame 602 to drive the steel rollers 603 to move up and down, which is convenient for use.

[0049] In the present Embodiment 1, the number of the Z-axis automatic telescopic rods 601 is two, and the two Z-axis automatic telescopic rods 601 are arranged in parallel and at intervals.

The control panel 9 outputs a control signal to independently control the operation of the Z-axis automatic telescopic rod 601. The Z-axis automatic telescopic rod 601 operates to drive the roller frame 602 to drive the steel roller 603 to move up and down, so as to adjust the position of the steel roller 603.

[0067] The control output end of the control panel 9 is electrically connected to the control input end of the two-way automatic telescopic rod 703 of the lifting type upper grinding assembly 7. The control panel 9 outputs a control signal to independently control the operation of the two-way automatic telescopic rod 703. The two-way automatic telescopic rod 703 operates to drive the steel plate 704 to drive the rectangular grinding sheet 705 to move up and down, so as to adjust the position of the rectangular grinding sheet 705.

[0068] The control output end of the control panel 9 is respectively electrically connected to the control input ends of the X-axis automatic telescopic rod 803, the Y-axis automatic telescopic rod 805 and the automatic gripper 806 of the progressive movement assembly 8. The control panel 9 outputs a control signal to independently control the operation of the X-axis automatic telescopic rod 803, the Y-axis automatic telescopic rod 805 and the automatic gripper 806.

The control panel 9 outputs a control signal to independently control the operation of the belt drive assembly 1002. The belt drive assembly 1002 operates to drive the lower grinding roller 1001 to rotate and perform a grinding and polishing operation.

[0070] The present invention also provides a method for forming and grinding a steel skeleton of a light roof panel. Based on the above-mentioned equipment for forming and grinding a steel skeleton of a light roof panel, it includes the following steps: S101: Take out the square-mouth steel skeleton to be polished, check whether there are obvious defects, scratches or deformations on its surface. If necessary, perform preliminary cleaning to remove surface impurities or oil stains to ensure the polishing effect. Then place the square-mouth steel skeleton on the stepped part of the outer wall of the convex-character workpiece table 2, ensuring that the square-mouth steel skeleton is stable and in the correct position. At this time, one end of the square-mouth steel skeleton needs to pass through the middle of the frame 1 and be clamped by the automatic claw 806 of the progressive movement assembly 8 to ensure that there is no displacement or loosening during the entire polishing process.

[0071] S102: Turn on the double-position sand belt grinding assembly 3, the lower polishing assembly 10, and the lifting upper grinding assembly 7 to work through the control panel 9. The double-position sand belt grinding assembly 3 is used to polish one side outer wall surface of the square-mouth steel skeleton. Then adjust the positions of the lifting upper grinding assembly 7 and the lower polishing assembly 10 to polish the top and bottom surfaces of the square-mouth steel skeleton together. The progressive movement assembly 8 pulls the square-mouth steel skeleton during the polishing process, so that the double-position sand belt grinding assembly 3, the lifting upper grinding assembly 7, and the lower polishing assembly 10 cooperate to perform repeated polishing operations on the outer surface of the square-mouth steel skeleton.

[0072] In the step S102, the working principle of the double-position sand belt grinding assembly 3 is as follows: First, the control panel 9 controls the bidirectional lead screw electric module 302 to work to drive the two frames 303 to move in the direction of approaching or separating from each other. At this time, the frame 303 can drive the sand belt grinding machine 304 to move in the direction of approaching or departing from the stepped part of the convex-character workpiece table 2, realizing the adjustment of the position of the sand belt grinding machine 304 in the X-axis direction. At this time, by adjusting the position of the sand belt grinding machine 304 in the X-axis direction, the contact force between the sand belt grinding machine 304 and the square-mouth steel skeleton can be adjusted; then the control panel 9 controls the sand belt grinding machine 304 to work to polish the corresponding outer side surface of the square-mouth steel skeleton.

[0073] In the step S102, the working principle of the lower polishing assembly 10 is as follows: The control panel 9 controls the belt drive assembly 1002 to start. The belt drive assembly 1002 is used to drive the lower grinding roller 1001 to rotate, and the rotation of the lower grinding roller 1001 is used to polish the lower surface of the square-mouth steel skeleton.

[0074] In the step S102, the working principle of the lifting upper grinding assembly 7 is as follows: The control panel 9 controls the bidirectional automatic telescopic rod 703 to start. The bidirectional automatic telescopic rod 703 is used to drive the steel plate 704 to drive the rectangular grinding sheet 705 to move up and down, so that the rectangular grinding sheet 705 contacts the upper surface of the square-mouth steel skeleton; at this time, controlling the downward movement position of the rectangular grinding sheet 705 can be used to control the downward pressure.

[0075] In the step S102, the working principle of the progressive movement assembly 8 is as follows: The control panel 9 controls the X-axis automatic telescopic rod 803, the Y-axis automatic telescopic rod 805, and the automatic gripper 806 to work independently. The X-axis automatic telescopic rod 803 works to drive the slide 802 to slide within the rectangular frame 801, so as to adjust the position of the automatic gripper 806 in the X-axis direction; make the position of the automatic gripper 806 correspond to the position of the square steel skeleton to be clamped. The automatic gripper 806 works to perform a clamping operation on the square steel skeleton; the Y-axis automatic telescopic rod 805 works to drive the support arm 804 to move on the slide 802, and the support arm 804 drives the automatic gripper 806 and the clamped square steel skeleton to move back and forth; make the square steel skeleton perform repeated grinding and polishing operations.

[0076] S103: After one side of the square steel skeleton is polished, the operator needs to manually rotate the square steel skeleton to the other side and reposition it on the convex character workpiece table 2 to ensure that the unprocessed side can be polished subsequently, and use the same method to process the remaining unpolished sides to ensure that all sides achieve a consistent polishing effect; S104: After all sides are ground and polished, turn off the equipment, take out the square steel skeleton, and conduct a surface inspection; confirm whether the surface of the square steel skeleton is smooth, without scratches, defects or unpolished areas. If necessary, perform local trimming, and clean the surface of the equipment and the working area to remove residual sand chips and polishing debris.

[0077] Embodiment 2: As Figure 9 shown, based on the above Embodiment 1, in this Embodiment 2, the progressive movement assembly 8 can also adopt Figure 9 the structure shown. The progressive movement assembly 8 includes a rectangular frame 801 fixedly installed on the back of the housing frame 1. Two symmetrically arranged slides 802 are slidably installed inside the rectangular frame 801. A support arm 804 is slidably installed on the slide 802. The support arm 804 is arranged along the Y-axis direction. An automatic gripper 806 is installed on one side of the support arm 804 close to the discharge end of the rolling type feeding mechanism 6, and the other end of the support arm 804 is arranged towards the direction of the double-position sand belt grinding assembly 3.

[0078] At the positions close to the inner surfaces of the upper side and the lower side inside the rectangular frame 801, a guide post 807 and a driving lead screw 808 are respectively arranged. The guide post 807 and the driving lead screw 808 are parallel and arranged at intervals.

[0079] Both ends of the guide post 807 are fixedly connected to the inner side surface of the rectangular frame 801. Two sliding seats 814 are slidably connected to the guide post 807. The two sliding seats 814 are respectively fixedly connected to the corresponding slides 802. Through the cooperation of the guide post 807 and the sliding seats 814, the slides 802 are slidably installed inside the rectangular frame 801, which is convenient for assembly and installation.

[0080] Both ends of the driving lead screw 808 are rotatably connected to the U-shaped frame 801 through bearings. Two threaded sections are symmetrically arranged on the driving lead screw 808. The thread directions of the two threaded sections are opposite, and driving threaded blocks 809 are respectively threadedly connected to the two threaded sections. The two driving threaded blocks 809 are fixedly connected to the corresponding sliding seats 802.

[0081] An X-axis motor 810 is fixedly installed on the outer side surface of the U-shaped frame 801. The power output end of the X-axis motor 810 is drivingly connected to one end of the driving lead screw 808.

[0082] When the X-axis motor 810 is started, it is used to drive the driving lead screw 808 to rotate forward and backward. The rotation of the driving lead screw 808 drives the two sliding seats 802 to move towards or away from each other through the cooperation of the threads and the two driving threaded blocks 809, so as to adjust the positions of the support arm 804 and the automatic gripper 806 in the X-axis direction.

[0083] A driving gear 812 is rotatably installed below the support arm 804 inside the sliding seat 802. A moving rack 811 is fixedly installed on the lower surface of the support arm 804. The driving gear 812 is meshed with the moving rack 811. A Y-axis motor 813 is fixedly installed on the side surface of the sliding seat 802. The power output end of the Y-axis motor 813 is drivingly connected to the driving gear 812.

[0084] With such a design, when the Y-axis motor 813 is started, it is used to drive the driving gear 812 to rotate forward and backward. The driving gear 812 is meshed with the moving rack 811. When the driving gear 812 rotates, it can drive the support arm 804 to move through the cooperation of the moving rack 811. At this time, the support arm 804 drives the automatic gripper 806 to reciprocate in the Y-axis direction, which is convenient for use.

[0085] In the second embodiment, the X-axis motor 810 and the Y-axis motor 813 are both prior arts. A driving motor that is normally sold on the market can be adopted, and its specific model can be selected according to the actual load force. Details are not described herein.

[0086] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
