Description

Technical Field

[0001] The utility model relates to the technical field of metal structural part manufacturing process, and further relates to a shelf frame processing and positioning device for a material rack. Background Art

[0002] During heat treatment of aluminum alloy extruded profiles, in order to save energy and increase furnace loading, multiple layers of profiles need to be placed on the rack. In order to heat the profiles evenly during heat treatment to ensure stable performance, each layer needs to be separated by shelves for uniform heating.

[0003] Combination Figure 1 and Figure 2 As shown, a plurality of shelf racks 02 are respectively arranged on the left and right sides of the rack base 01, and the left and right shelf racks 02 jointly support the shelf 03, and a layer of shelves 03 at the same height jointly support the aluminum alloy extruded profile 04. Multiple layers of shelves 03 can be placed on the shelf rack 02, thereby meeting the placement requirements of multiple layers of aluminum alloy extruded profiles 04. With the improvement of automation in the main plant of aluminum alloy extruded profiles, when the extruder extrude the profile, the shelf 03 is automatically placed at the set shelf rack 02 position synchronously, and then the profile is hoisted into the rack, and the operation is repeated for each layer until the rack is full.

[0004] Since the entire rack is heated in the furnace together with the profile, the wall thickness of the shelf rack 02 is required to be thicker to withstand the heating and load requirements. The thick wall thickness causes the geometric accuracy of the shelf rack 02 to be poor after the flat sleeve is cut and bent. Therefore, the current production process is to bend first, then cut, and then drill holes, but the material utilization rate is low, and the bending angle is difficult to ensure consistency. When the size deviation of the shelf rack is large, the shelf rack often gets stuck and falls, requiring manual intervention and affecting production efficiency. Therefore, the size consistency requirements of the shelf rack are high.

[0005] Combination Figure 3 As shown, the left and right shelf frames 02 are formed by cutting a steel groove to be cut, which solves the problem of inconsistent bending angles and improves material utilization. The traditional cutting positioning method relies on manual marking. In practical applications, there are the following problems: the error of marking and drilling is large, the consistency of cutting size is difficult to ensure, resulting in installation difficulties and inconsistent shelf position heights.

[0006] For those skilled in the art, how to improve the processing accuracy of the shelf is a technical problem that needs to be solved at present. Utility Model Content

[0039] The core of the utility model is to provide a shelf frame processing and positioning device for a material rack, wherein a drilling positioning tool and a cutting positioning tool are used to position the workpiece respectively, thereby improving the processing accuracy of the shelf frame.

[0040] In order to enable those skilled in the art to better understand the technical solution of the present invention, the shelf rack processing and positioning device for the material rack of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] The utility model provides a shelf frame processing positioning device for a material rack, comprising a drilling positioning tool 1 and a slitting positioning tool 2. The drilling positioning tool 1 is used for positioning during drilling, and the slitting positioning tool 2 is used for positioning during slitting.

[0042] Combination Figure 4 , Figure 5 , Figure 6As shown, the drilling positioning tool 1 includes a drilling base 11 and a rotating support frame 12. The drilling base 11 is used to locate the position of the entire drilling positioning tool 1. The two ends of the rotating support frame 12 are respectively rotatably installed on the drilling base 11. The rotating support frame 12 can rotate relative to the drilling base 11, and the rotating axis of the rotating support frame 12 is horizontal and along the X-axis direction.

[0043] The drilling base 11 is used to be fixed on the radial drilling machine to provide support, and the rotating support frame 12 is used to support the groove steel to be cut (the groove steel to be cut is as follows Figure 4 As shown in A). The rotating support frame 12 is provided with an end positioning member 13, a lateral positioning member 14 and a locking member 15. The end positioning member 13 is used to position at least one end of the grooved steel to be cut. The end positioning member 13 is used as the end positioning structure of the grooved steel to be cut and is the reference for end positioning. The lateral positioning member 14 is used to position the wing plate on one side of the grooved steel to be cut, and to press and fix the grooved steel to be cut. The position of the grooved steel to be cut is positioned by the end and the side. The locking member 15 is used to lock the grooved steel to be cut to prevent the grooved steel to be cut from being separated from the rotating support frame 12.

[0044] When drilling the grooved steel to be cut, keep the rotating support frame 12 in a horizontal state, place the grooved steel to be cut on the upper surface of the rotating support frame 12, and the lower part of the grooved steel to be cut contacts the upper surface of the rotating support frame 12. One end of the grooved steel to be cut is pressed against the end positioning member 13, and the lateral positioning member 14 presses the wing plate of the grooved steel to be cut from the side, and finally presses to the upper part of the grooved steel to be cut through the locking member 15, so that the grooved steel to be cut is three-dimensionally positioned and tightened. Then rotate the rotating support frame 12 about 90 degrees, so that one side wing plate of the grooved steel to be cut faces upward, and the other side wing plate faces downward (such as Figure 4-Figure 6 The position and size of the holes on the wing plates on both sides of the steel to be cut can be the same or different. Then, the rotating support frame 12 is rotated in the opposite direction by about 180 degrees to switch the orientation of the wing plates, so that the wing plates originally facing downward are facing upward and the wing plates originally facing upward are facing downward, and the wing plates facing upward in this state are drilled. The drilling operation on the wing plates on both sides of the steel to be cut is now completed. The steel to be cut is driven to rotate by the rotating support frame 12, so that the wing plates on both sides are respectively facing the drill bit above to achieve drilling.

[0045] In the above-mentioned drilling process, the drilling process of the wing plates on both sides only requires rotating the groove steel to be cut, which can ensure that the drilling positions of the wing plates on both sides are accurately aligned to avoid deviation.

[0046] Combination Figures 7 to 11As shown, the slitting and positioning tool 2 includes a slitting base 21, a support block 22, an end stopper 23 and a lateral clamping member 24. The slitting base 21 is used to be fixed on the CNC flame cutting machine to position and fix the entire slitting and positioning tool 2; at least two support blocks 22 are arranged on the slitting base 21, and the support blocks 22 protrude from the slitting base 21. The two support blocks 22 are used to support the grooved steel to be cut that has been drilled.

[0047] The end stopper 23 is used to position one end of the groove steel to be cut. Before cutting, one end of the groove steel to be cut is pressed against the end stopper 23, and one end of the groove steel to be cut is tightened and positioned by the end stopper 23. The lateral tightening member 24 is used to press the groove steel to be cut, so that the groove steel to be cut is positioned laterally, and the groove steel to be cut is tightened and fixed.

[0048] After the slot steel to be cut is fixed in place, the cutting positioning tool 2 is used to position the slot steel to be cut to achieve cutting, and the shelf frame is formed after the slot steel is cut. Figures 7 to 11 As shown in B, the cutting gun is shown in C in the figure. The cutting gun moves relative to the groove steel to be cut according to a certain trajectory, so that the groove steel to be cut is divided into two shelves.

[0049] The utility model cooperates with each other to position the drilling positioning tool 1 and the slitting positioning tool 2. The groove steel to be cut is first fixed by the drilling positioning tool 1 to accurately drill holes on the groove steel to be cut, and then the groove steel to be cut is transferred to the slitting positioning tool 2, and is positioned by the slitting positioning tool 2 so that the cutting gun can accurately cut out the shelf frame. The drilling positioning tool 1 and the slitting positioning tool 2 can both provide accurate positioning for the groove steel to be cut, so as to improve the accuracy of drilling and slitting, and improve the processing accuracy of the shelf frame.

[0050] On the basis of the above scheme, the center of gravity of the rotating support frame 12 in the utility model is lowered, so as to keep the web of the steel to be cut facing upward. That is, in the absence of other external forces, the rotating support frame 12 automatically maintains a horizontal state, so that the steel to be cut can be placed with the web facing upward, thereby facilitating the placement of the steel to be cut.

[0051] Combination Figure 4 As shown, the rotating support frame 12 includes a bottom plate 121 and side plates 122 . Two side plates 122 are arranged on one bottom plate 121 . The bottom plate 121 is used to support the grooved steel to be cut, and the grooved steel to be cut is located between the two side plates 122 .

[0052] Drill sleeves 1221 for locating the drilling position are respectively arranged on the two side plates 122. The drill sleeves 1221 are used to assist in locating the drilling position of the drill bit. When drilling, the drill bit passes through the drill sleeves 1221 to drill holes on the two side wing plates of the grooved steel to be cut. A drill sleeve 1221 is correspondingly arranged for each drilling position.

[0053] A bearing seat 17 is provided on the drilling base 11 or the end positioning member 13, and the bearing seat 17 is hinged to the drilling base 11 so that the drilling base 11 and the end positioning member 13 can smoothly rotate relative to the drilling base 11. The inner ring of the bearing provided inside the bearing seat 17 is connected to the support shaft provided on the drilling base 11.

[0054] Combination Figure 4 As shown, the locking member 15 includes a hinge pin 151, a pressure plate 152 and a locking screw 153. One end of the pressure plate 152 is hinged to the side plate 122 through the hinge pin 151, and the hinge pin 151 serves as the rotation axis of the pressure plate 152. The other end of the pressure plate 152 is locked to another side plate 122 through the locking screw 153, so that the pressure plate 152 is pressed on the web of the steel to be cut. The height of the side plate 122 is slightly lower than the wing plate of the steel to be cut, so that the web of the steel to be cut is slightly higher than the side plate 122, thereby ensuring that the pressure plate 152 is pressed on the web of the steel to be cut.

[0055] Combination Figure 4 As shown, the lateral positioning member 14 is a lateral pressure screw arranged on the side plate 122, which can be pressed against the wing plate of the steel to be cut. A threaded hole is arranged on the side plate 122, and the lateral pressure screw is threadedly connected to the threaded hole. The lateral pressure screw passes through the threaded hole and is pressed against one wing plate of the steel to be cut, so that the other wing plate of the steel to be cut is pressed onto the other side plate 122, thereby realizing the lateral positioning and pressing of the steel to be cut.

[0056] On the basis of any of the above technical solutions and their combination, a positioning handle 16 is provided at one end of the rotating support frame 12, and the positioning handle 16 is fixed to the rotating support frame 12 and can rotate synchronously with the rotating support frame 12. Two angle determination blocks 111 and locking nuts 112 are correspondingly provided on the drilling base 11. When the rotating support frame 12 rotates 90 degrees forward or 90 degrees reverse, the positioning handle 16 contacts one of the angles for positioning the drilling angle of the rotating support frame 12; the two angle determination blocks 111 contact the positioning handle 16 to position the drilling angle of the rotating support frame 12.

[0057] The locking nut 112 is used to lock the positioning handle 16 to the angle determining block 111. The locking nut 112 is installed on the angle determining block 111. Each angle determining block 111 is provided with a locking nut 112. When the positioning handle 16 contacts the rotating support frame 12, the locking nut 112 locks the positioning handle 16 to keep it in the drilling position.

[0058] Combination Figure 4As shown, a balancing block 18 is provided at the other end of the rotating support frame 12, and the balancing block 18 and the positioning handle 16 are respectively provided at the two ends of the rotating support frame 12. Two balancing limiting blocks 113 are correspondingly provided on the drilling base 11, and the two balancing limiting blocks 113 respectively contact the balancing block 18 to locate the drilling angle of the rotating support frame 12 and provide support. When the rotating support frame 12 rotates forward or reversely so that the positioning handle 16 contacts one of the rotating support frames 12, the balancing block 18 contacts one of the balancing limiting blocks 113 at the same time, ensuring that the two ends of the rotating support frame 12 are stably supported to avoid vibration during drilling that affects the accuracy.

[0059] Combination Figure 7 , Fig. 9 As shown, the support block 22 is used to support the inner side of the web, and the position of the support block 22 avoids the cutting path of the cutting gun. The lateral pressing member 24 is used to press the outer side of the wing plate of the groove steel to be cut, so that the inner side of the wing plate contacts the support block 22, thereby forming a positioning for the groove steel to be cut.

[0060] Combination Figure 7 As shown, the lateral tightening member 24 includes a tightening pin 241 and a tightening nut 242 . The tightening nut 242 is fixedly disposed on the slitting base 21 . The tightening pin 241 is provided with an external thread and can be threadedly connected to the tightening nut 242 .

[0061] Combination Fig.10 As shown, a stepped pin is provided at the end of the clamping pin 241 to be inserted into the hole drilled on the wing plate of the steel groove to be cut. The outer diameter of the stepped pin is smaller and can be inserted into the hole drilled on the wing plate of the steel groove to be cut. The hole positions on the wing plates on both sides of the steel groove to be cut are different. The stepped pin is provided at the end of the step of the clamping pin 241 to prevent mistakes and determine that the direction of the channel steel wing plate is placed correctly. If it cannot enter this hole, it means that the hole of the channel steel wing plate is placed incorrectly and the direction needs to be changed to prevent waste.

[0062] Specifically, the support block 22 is detachably arranged on the cutting base 21, and the position of the support block 22 can be adjusted accordingly according to the specific specifications of the channel steel to be cut.
