Description

Technical Field

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

[0002] The basic structure of steel frame lightweight wall panels mainly consists of three parts: square-mouth steel frame, lightweight core material and panel. Among them, the square-mouth steel frame is the main load-bearing structure of the wall. It is made of cold-bent thin-walled steel plates that are bent and welded. It has excellent seismic resistance and load-bearing performance. The lightweight core material is filled inside the steel frame. It usually uses lightweight concrete and other materials. It has sound insulation, heat insulation, fire resistance and other properties. The square-mouth steel frame of the lightweight roof panel needs to be polished during the production process to produce high-quality frame profiles that meet design requirements.

[0003] The Chinese utility model patent application number is CN202223310955.6, which discloses a polishing device for metal frames, including a processing table, four electric telescopic rods are fixedly connected to the top of the processing table, a mounting plate is fixedly connected between the four electric telescopic rods, a mounting slider is slidably connected inside the mounting plate, a polishing assembly is connected to the bottom of the mounting slider, a drive assembly is connected to the front of the mounting plate, two symmetrical movable grooves are opened on the top of the processing table, and a movable slider is slidably connected inside the movable groove.

[0004] The above-mentioned existing grinding and polishing equipment uses a polishing wheel to grind and polish the formed steel frame to ensure that the surface of the steel frame 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 frames of different specifications.

[0005] However, the use effect of this type of existing grinding and polishing equipment is relatively poor. During one clamping process, it can only perform single-side grinding and polishing operations on the steel frame. When it is necessary to grind and polish multiple sides of the steel frame, the steel frame needs to be clamped multiple times, which reduces the use effect. In addition, this type of existing grinding and polishing equipment uses the downward movement and rotation of the polishing wheel to grind the steel frame. During the clamping and grinding operations, due to clamping errors and errors in the distance of each downward movement, it is easy to make it difficult to ensure consistent polishing effects on each side of the steel frame, which reduces the use effect and reduces the production accuracy, production quality and production efficiency. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a light roof panel steel frame forming and polishing equipment and method, which is used to solve the problem that the existing polishing equipment can only polish one side at a time during clamping, and due to clamping errors and polishing errors, it is difficult to ensure the consistency of the polishing effects of each side of the steel frame, and the steel frame cannot be fully polished with high precision and high efficiency, which reduces the use effect.

Place the square-mouth steel frame on the stepped portion of the outer wall of the embossed worktable to ensure that the square-mouth steel frame is stable and positioned correctly.

At this time, through the cooperation of the double-position sand belt grinding assembly, the lower polishing assembly and the lifting upper grinding assembly, different side walls of the square steel frame can be ground and polished; thereby, it is possible to achieve synchronous grinding and polishing operations on multiple side surfaces of the square steel frame during one clamping and movement of the square steel frame, thereby improving the grinding and polishing effect and production rate, ensuring uniform surface finish, and reducing the inconsistency caused by human operation.

[0025] 2. In the present invention, the lower polishing assembly and the lifting upper grinding assembly respectively perform grinding and polishing operations on the bottom and top surfaces of the square steel frame, ensuring that each side surface can be fully and evenly processed, and multiple surfaces are processed synchronously and continuously, reducing the number of clamping times and adjustment errors, and ensuring the stability and consistency of the polishing effect.

[0026] 3. The clamping and moving method of the progressive moving assembly in the present invention can achieve stable clamping and moving operations on the square steel frame, avoiding displacement or deformation during the polishing process, and ensuring that each side can be polished according to the predetermined angle and position.

The top of the telescopic end of the two Z-axis lifting units 4 is fixedly installed with a lower connecting beam 5, and the back of the lower connecting beam 5 is installed with a rolling-type feeding mechanism 6, a lifting-type upper grinding assembly 7 is provided on the shell frame 1 at the upper position of the lower connecting beam 5, a lower polishing assembly 10 is installed inside the shell frame 1, and a progressive moving assembly 8 for pulling the square-mouth steel frame below the lifting-type upper grinding assembly 7 and moving it along the Y-axis direction is installed on the back of the shell frame 1.

[0040] In this embodiment 1, stepped portions are respectively provided on the outer walls of both sides of the embossed workpiece platform 2, and the two stepped portions are used to place the square-mouth steel frame to be ground and polished.

[0041] In this embodiment 1, the Z-axis lifting unit 4 adopts one of a hydraulic cylinder, a telescopic cylinder, and an electric telescopic rod. The Z-axis lifting unit 4 works to extend or retract its telescopic end to drive the lower connecting beam 5 to move up and down. When the lower connecting beam 5 is upgraded and moved, it drives the rolling-type feeding mechanism 6 to move up and down, which is convenient to use.

[0042] like Figure 5 As shown, the progressive moving assembly 8 includes a circular frame 801 fixed on the back of the shell frame 1, and two symmetrically arranged slides 802 are slidably installed inside the circular frame 801. A support arm 804 is slidably installed on the slide 802, and the support arm 804 is arranged along the Y-axis direction. An automatic clamp 806 is installed on the side of the support arm 804 close to the discharge end of the rolling feeding mechanism 6, and the other end of the support arm 804 is arranged toward the direction of the double-position belt grinding assembly 3.

[0043] In this embodiment 1, the two slides 802 move toward or away from each other to adjust the distance between the two support arms 804, thereby adjusting the position of the automatic clamp 806 in the X-axis direction, which is convenient for use; the support arm 804 slides on the slide 802 to adjust the position of the automatic clamp 806 in the Y-axis direction.

[0044] In this embodiment 1, the automatic clamp 806 adopts one of a mechanical automatic clamp or a pneumatic clamp. The automatic clamp 806 has two working states, namely an open working state and a clamping working state. When the automatic clamp 806 is in the open working state, the clamping part of the automatic clamp 806 is separated from the square-mouth steel frame, and the square-mouth steel frame can be removed from the automatic clamp 806; when the automatic clamp 806 is in the clamping working state, the clamping part of the automatic clamp 806 is used to clamp the end of the square-mouth steel frame, which is convenient to use.

[0045] Guide columns 807 for guiding the slide 802 to slide are fixedly installed near the upper and lower inner surfaces inside the circular frame 801. The guide columns 807 are arranged along the moving direction of the slide 802, and the slide 802 and the guide columns 807 are slidably connected. The slide 802 can slide on the guide columns 807, thereby improving the stability of the slide 802 during movement.

[0046] X-axis automatic telescopic rods 803 are installed on the left and right outer walls of the circular frame 801. The telescopic ends of the two X-axis automatic telescopic rods 803 are arranged in a direction close to each other, and the telescopic ends of the two X-axis automatic telescopic rods 803 pass through the outer wall of the circular frame 801 and are fixedly connected to the outer wall of the corresponding slide 802.

[0047] The X-axis automatic telescopic rod 803 works to extend or retract its telescopic end. At this time, the telescopic end of the X-axis automatic telescopic rod 803 can drive the slide 802 to move in the return frame 801, thereby adjusting the position of the slide 802 in the X-axis direction.

[0048] In this embodiment 1, the X-axis automatic telescopic rod 803 adopts one of a hydraulic cylinder, a telescopic cylinder, and an electric telescopic rod.

[0049] A Y-axis automatic telescopic rod 805 is fixedly installed on the slide 802 for driving the support arm 804 to move along the Y-axis direction. The main part of the Y-axis automatic telescopic rod 805 is arranged toward the direction of the double-position belt grinding assembly 3, and the telescopic end of the Y-axis automatic telescopic rod 805 is fixedly connected to the support arm 804.

[0050] The Y-axis automatic telescopic rod 805 works to extend or retract its telescopic end. At this time, the telescopic end of the Y-axis automatic telescopic rod 805 can drive the support arm 804 to move on the slide 802 to adjust the position of the automatic clamp 806 in the Y-axis direction.

[0051] In this embodiment 1, the Y-axis automatic telescopic rod 805 adopts one of a hydraulic cylinder, a telescopic cylinder, and an electric telescopic rod.

[0052] With this design, the working principle of the progressive moving assembly 8 is as follows: the staff places the square-mouth steel frame on the stepped portion on the outer wall of the convex workpiece table 2, and then passes the square-mouth steel frame through the middle of the shell frame 1 until the end of the square-mouth steel frame is located between the two clamping parts of the automatic clamp 806, and then the automatic clamp 806 is started to clamp the end of the square-mouth steel frame, so as to achieve the purpose of stabilizing the square-mouth steel frame, ensuring that no deviation or vibration occurs during the processing, and convenient use.

[0053] Before the automatic clamp 806 clamps the square steel frame, the staff can push the slide 802 to move in the X-axis direction through the X-axis automatic telescopic rod 803. The movement of the slide 802 drives the automatic clamp 806 to move in the X-axis direction through the support arm 804, thereby adjusting the position of the automatic clamp 806 for easy use.

[0054] After the automatic clamp 806 clamps the end of the square-mouth steel frame, the Y-axis automatic telescopic rod 805 is started to push the support arm 804 to drive the automatic clamp 806 to move back and forth. At this time, the automatic clamp 806 drives the square-mouth steel frame to move back and forth 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-mouth steel frame is polished during the continuous movement, thereby avoiding the joint defects in traditional continuous processing production, and ensuring the consistency of the surface texture direction after polishing through the linear motion trajectory. After the three sides of the square-mouth steel frame are polished, the profile only needs to be turned horizontally to process the remaining sides without the need to recalibrate the reference surface.

[0059] A bidirectional screw electric module 302 is fixedly installed on the inner bottom surface of the auxiliary frame 301. The two moving ends of the bidirectional screw electric module 302 are fixedly connected to the corresponding frames 303 respectively. The bidirectional screw electric module 302 is used to drive the two frames 303 to move towards or away from the embossed workpiece table 2 respectively.

[0060] The bidirectional screw electric module 302 includes a bidirectional screw, which is provided with two symmetrically arranged threaded segments. The thread rotation directions of the two threaded segments are opposite. The two threaded segments are respectively threadedly connected with thread blocks, and the two thread blocks are respectively fixedly connected to the corresponding frames 303.

At this time, the frame 303 can drive the belt grinder 304 to move closer to or away from the step part of the embossed workpiece table 2 until the belt grinder 304 contacts the outer wall of one side of the square-mouth steel frame. The belt grinder 304 is used to remove defects, burrs and oxide layers on the outer surface of the square-mouth steel frame to improve the surface quality.

[0062] The rolling transport mechanism 6 includes a roller frame 602 , which is arranged parallel to the lower connecting beam 5 , and a steel roller 603 is rotatably mounted on the roller frame 602 , which is arranged horizontally along the X-axis direction.

The Z-axis automatic telescopic rod 601 is used to drive the roller frame 602 to drive the steel roller 603 to move up and down, which is convenient to use.

[0064] In this embodiment 1, there are two Z-axis automatic telescopic rods 601 , and the two Z-axis automatic telescopic rods 601 are parallel and spaced apart, and the telescopic ends of the two Z-axis automatic telescopic rods 601 are respectively fixedly connected to the roller frame 602 .

[0066] In this design, the staff starts the Z-axis lifting unit 4 to drive the lower connecting beam 5 and the rolling conveying mechanism 6 to move upward until the distance between the steel roller 603 and the lower polishing assembly 10 is sufficient for the square-mouth steel frame to pass through, and then starts the Z-axis automatic telescopic rod 601 to push the roller frame 602 and the steel roller 603 to move downward, so that the steel roller 603 is pressed on the upper surface of the square-mouth steel frame to reduce the grinding and jumping of the square-mouth steel frame in the Z-axis direction and improve the grinding and polishing effect.

[0067] In this embodiment 1, the Z-axis automatic telescopic rod 601 adopts one of a hydraulic cylinder, a telescopic cylinder, and an electric telescopic rod.

[0085] The present invention also provides a method for forming and polishing a light roof panel steel frame, based on the above-mentioned light roof panel steel frame forming and polishing equipment, comprising the following steps:

[0086] S101: Take out the square-mouth steel frame to be ground and 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 frame on the stepped portion of the outer wall of the embossed workpiece table 2 to ensure that the square-mouth steel frame is stable and in the correct position. At this time, one end of the square-mouth steel frame needs to pass through the middle of the shell frame 1 and be clamped by the automatic clamp 806 of the progressive moving assembly 8 to ensure that it will not be displaced or loosened during the entire polishing process.

[0087] S102: Turn on the double-position sanding belt grinding assembly 3, the lower polishing assembly 10, and the lifting upper grinding assembly 7 through the control panel 9 to start working. The double-position sanding belt grinding assembly 3 is used to grind and polish the outer wall surface of one side of the square mouth steel frame. Then adjust the positions of the lifting upper grinding assembly 7 and the lower polishing assembly 10 to grind and polish the top and bottom surfaces of the square mouth steel frame together. The progressive moving assembly 8 pulls the square mouth steel frame during the polishing process, so that the double-position sanding belt grinding assembly 3, the lifting upper grinding assembly 7, and the lower polishing assembly 10 work together to repeatedly grind and polish the outer surface of the square mouth steel frame.

[0088] In the step S102, the working principle of the double-position belt grinder assembly 3 is: first, the control panel 9 controls the bidirectional screw electric module 302 to drive the two frames 303 to move toward or away from each other. At this time, the frame 303 can drive the belt grinder 304 to move toward or away from the step portion of the embossed workpiece table 2, thereby adjusting the position of the belt grinder 304 in the X-axis direction. At this time, by adjusting the position of the belt grinder 304 in the X-axis direction, the contact force between the belt grinder 304 and the square-mouth steel frame can be adjusted; then the control panel 9 controls the belt grinder 304 to perform grinding and polishing operations on the corresponding outer side surfaces of the square-mouth steel frame.

[0089] In the step S102, the working principle of the lower polishing assembly 10 is: the control panel 9 controls the belt drive component 1002 to start, the belt drive component 1002 is used to drive the lower grinding roller 1001 to rotate, and the lower grinding roller 1001 rotates to perform grinding and polishing operations on the lower surface of the square steel frame.

[0090] In the step S102, the working principle of the lifting type upper grinding assembly 7 is: the control panel 9 controls the start-up of the bidirectional automatic telescopic rod 703, and the bidirectional automatic telescopic rod 703 is used to drive the steel plate 704 to drive the rectangular grinding piece 705 to move up and down, so that the rectangular grinding piece 705 contacts the upper surface of the square steel frame; at this time, controlling the downward position of the rectangular grinding piece 705 can be used to control the downward pressure.

[0091] In the step S102, the working principle of the progressive movement assembly 8 is: the control panel 9 controls the X-axis automatic telescopic rod 803, the Y-axis automatic telescopic rod 805 and the automatic clamp 806 to work independently, the X-axis automatic telescopic rod 803 is used to drive the slide 802 to slide in the return frame 801, so as to adjust the position of the automatic clamp 806 in the X-axis direction; the position of the automatic clamp 806 corresponds to the position of the square-mouth steel frame to be clamped, and the automatic clamp 806 is used to perform a clamping operation on the square-mouth steel frame; the Y-axis automatic telescopic rod 805 is used to drive the support arm 804 to move on the slide 802, and the support arm 804 drives the automatic clamp 806 and the clamped square-mouth steel frame to move back and forth; so that the square-mouth steel frame is repeatedly ground and polished.

[0092] S103: After polishing one side of the square-mouth steel frame, the staff needs to manually rotate the square-mouth steel frame to the other side and reposition it on the embossing workpiece table 2 to ensure that the unprocessed side can be polished subsequently. The staff also uses the same method to process the remaining unpolished sides to ensure that all sides achieve a consistent polishing effect.

[0093] S104: After completing the grinding and polishing operations on all sides, turn off the equipment, remove the square-mouth steel frame, and perform a surface inspection; confirm whether the surface of the square-mouth steel frame is smooth, without scratches, defects or unpolished areas, and perform local trimming if necessary, and clean the equipment surface and work area to remove residual sand and polishing debris.

[0094] Example 2: Figure 9 As shown, based on the above embodiment 1, in this embodiment 2, the progressive movement assembly 8 can also be used Figure 9 In the structure shown, the progressive moving assembly 8 includes a circular frame 801 fixedly mounted on the back of the shell frame 1, and two symmetrically arranged slides 802 are slidably mounted inside the circular frame 801. A support arm 804 is slidably mounted on the slide 802, and the support arm 804 is arranged along the Y-axis direction. An automatic clamp 806 is installed on the 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 toward the direction of the double-position belt grinding assembly 3.

[0095] A guide post 807 and a driving screw 808 are respectively provided at positions near the upper and lower inner surfaces of the return frame 801 . The guide post 807 and the driving screw 808 are arranged in parallel and at intervals.

[0096] The two ends of the guide column 807 are fixedly connected to the inner side of the circular frame 801 respectively. Two sliding seats 814 are slidably connected to the guide column 807. The two sliding seats 814 are fixedly connected to the corresponding slides 802 respectively. The slide 802 is slidably installed in the circular frame 801 through the cooperation of the guide column 807 and the sliding seat 814, which is convenient for assembly and installation.

[0097] The two ends of the driving screw 808 are rotatably connected to the return frame 801 through bearings. Two threaded sections are symmetrically arranged on the driving screw 808. The threads on the two threaded sections have opposite rotation directions, and the two threaded sections are respectively threadedly connected to driving thread blocks 809. The two driving thread blocks 809 are fixedly connected to the corresponding slide seats 802.

[0098] An X-axis motor 810 is fixedly mounted on the outer surface of the return frame 801 , and a power output end of the X-axis motor 810 is transmission-connected to one end of the driving screw 808 .

[0099] The X-axis motor 810 is started to drive the driving screw 808 to rotate forward and reverse. The rotation of the driving screw 808 drives the two slides 802 to move closer to or away from each other through the cooperation of the thread and the two driving thread blocks 809, thereby adjusting the position of the support arm 804 and the automatic clamp 806 in the X-axis direction.

[0100] A driving gear 812 is rotatably installed in the slide 802 below the support arm 804, and 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 of the slide 802, and the power output end of the Y-axis motor 813 is transmission-connected to the driving gear 812.

[0101] With this design, the Y-axis motor 813 is started to drive the driving gear 812 to rotate forward and reverse. The driving gear 812 is engaged with the moving rack 811. The rotation of the driving gear 812 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 clamp 806 to move back and forth in the Y-axis direction, which is convenient to use.

[0102] In this embodiment 2, the X-axis motor 810 and the Y-axis motor 813 are both existing technologies and can adopt drive motors normally sold in the market. The specific models can be selected according to the actual load force and will not be described in detail here.
