Description

Technical Field

[0001] The invention relates to the field of angle steel processing equipment, and in particular to an angle steel opening and closing angle device. Background Art

[0002] Angle steel is an important raw material for manufacturing iron towers. In order to ensure that the iron tower is easy to install and the connection surface fits, and to increase the overall stiffness of the iron tower and the mechanical deformation capacity of the connecting parts, the installation parts of the iron tower, such as the ground wire, cross arm, and cross diaphragm, need to be opened or closed. Therefore, the angle steel often needs to be opened or closed before assembling the iron tower. In order to be able to open and close the angle of the angle steel, the patent announcement document CN205217803U discloses a mold that can open and close the angle of the angle steel. There are no corresponding guiding and clamping facilities on both sides of the mold for opening and closing the angle steel, so this structure cannot stably transport the angle steel, and the efficiency of the opening and closing operation is relatively low. Summary of the invention

[0003] In view of the above-mentioned problems, the present invention proposes a device for opening and closing the angle of angle steel. The device is provided with a pushing seat and a receiving seat on both sides of the base, and guide clamp assemblies are provided on both sides. Clamps are provided on the pushing seat and the receiving seat, which can clamp the angle steel and then drag it to move on the guide clamp assembly, thereby realizing the continuous operation of angle steel transportation and opening and closing the angle, and the opening and closing operation efficiency of the angle steel is higher.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A device for opening and closing angles of angle steel comprises a base, an extrusion driving member, a base template and a pressing template, wherein the base template is arranged on the base, the extrusion driving member is arranged on the base, and the pressing template is arranged on the extrusion driving member. The device also comprises a pushing platform, a receiving platform and a guide clamp assembly, wherein the pushing platform and the receiving platform are respectively located at two ends of the base, the guide clamp assembly is arranged on one side of the pushing platform, the guide clamp assembly is arranged on one side of the receiving platform, and the guide clamp assemblies are distributed on both sides of the base, a pushing seat is slidably arranged on the pushing platform, a receiving seat is arranged on the receiving platform, and clamps are arranged on both the pushing seat and the receiving seat.

[0006] The specific functions of this opening and closing angle device are as follows. First, the guide clamp assemblies located on both sides of the base can be used to guide and clamp the angle steel. After the clamps on the pushing seat clamp the angle steel, the pushing seat pushes the angle steel to move toward the base. When the position where the angle steel needs to be bent runs between the bottom template and the pressing template, the extrusion drive drives the pressing template to press down. The angle steel completes the opening and closing angle under the clamping and squeezing of the bottom template and the pressing template, and then the extrusion drive drives the pressing template to move upward. At this time, the receiving seat on the receiving platform moves toward the angle steel. After the clamps on the receiving seat clamp the angle steel, it drags the angle steel away from the base, causing the angle steel to slide into the guide clamp assembly on one side of the receiving platform.

[0007] To sum up, in this type of opening and closing angle device, a pushing seat and a receiving seat are respectively arranged on both sides of the base, and a guide clamp assembly is arranged on both sides. Both the pushing seat and the receiving seat are provided with clamps, which can clamp the angle steel and then drag and move it on the guide clamp assembly, thereby realizing the continuous operation of angle steel transportation and opening and closing angles, and the opening and closing angle operation of the angle steel is more efficient.

[0008] Optionally, it further includes a lifting cylinder, which is arranged on both sides of the base, and the guide clamp assembly is arranged on the cylinder rod of the lifting cylinder.

[0009] The functions of the lifting cylinders on both sides of the base are as follows: when the angle steel needs to pass between the bottom template and the pressure template, the cylinder rod of the lifting cylinder extends, so that the guide clamp assembly on the lifting cylinder contacts the angle steel, so that the angle steel does not contact the bottom template, so that the bottom template will not be worn during the dragging and conveying of the angle steel. When the angle steel needs to be opened and closed, the cylinder rod of the lifting cylinder is shortened, the guide clamp assembly on the lifting cylinder moves down, the guide clamp assembly on the lifting cylinder no longer contacts the angle steel, and the bottom template holds the angle steel. When the pressure template moves toward the bottom template, the opening and closing angle of the angle steel can be achieved through the extrusion of the bottom template and the pressure template.

[0010] Optionally, a guide rail is provided on the pushing support platform, and the pushing seat is slidably engaged with the guide rail on the pushing support platform, a rack is provided on the pushing support platform, and a pushing motor is provided on the pushing seat, and the shaft of the pushing motor is engaged with the rack on the pushing support platform through a gear, a guide rail is provided on the receiving support platform, and the receiving seat is slidably engaged with the guide rail on the receiving support platform, a rack is provided on the receiving support platform, and a receiving motor is provided on the receiving seat, and the shaft of the receiving motor is engaged with the rack on the receiving support platform through a gear.

[0011] The function of the guide rail and the rack is to ensure that the drag seat and the receiving seat can move stably.

[0012] Optionally, it also includes a clamping seat, a sliding rail is provided on the receiving seat, a slider is provided on the clamping seat, the slider is slidably matched with the sliding rail, a clamping clamp and a clamping cylinder are provided on the receiving seat, the clamping cylinder is matched with the clamping clamp, a floating guide rod is provided on the clamping seat, and the floating guide rod passes through the gap of the clamping clamp; the clamp is rotatably installed in the groove of the clamping seat through the center axis, and a damping buffer rod is provided between the clamp and the groove arm of the groove.

[0013] The specific clamping clamp can not only play the role of clamping the floating guide rod, but also play the role of guiding the floating guide rod. When the clamping clamp clamps the floating guide rod, the clamping seat cannot move up and down relative to the receiving seat (that is, float up and down), and when the clamping clamp no longer clamps the floating guide rod, the clamping seat is in a state where it can move up and down relative to the receiving seat. The function of the slide rail and the slider is to guide the up and down movement of the clamping seat, thereby avoiding stagnation of the clamping seat during the up and down movement.

[0014] Specifically in this device, the slide rail is perpendicular to the guide rail on the receiving platform, the up and down movement direction of the clamping seat is perpendicular to the sliding direction of the receiving seat, and the movement direction of the receiving seat is the direction of the dragging angle steel.

[0015] In this device, the clamp is installed in the groove of the clamping seat by rotating the central axis. The clamp can swing back and forth around the central axis in the groove. At the same time, since a damping buffer rod is arranged between the clamp and the groove wall of the groove, damping buffer rods are distributed on both sides of the clamp. The damping buffer rod can play a buffering role on the clamp. The existence of the damping buffer rod can ensure that the clamp will not touch the groove wall of the guide groove. The specific direction of the back and forth swinging of the clamp is perpendicular to the direction of the up and down lifting of the clamping seat.

[0016] The above-mentioned use of the clamping seat to elastically buffer the installation of the clamp has the following effects: first, after the angle steel is processed by the opening and closing angles, the angle steel is no longer in a straight line, but has a certain degree of bending or warping. Therefore, if the clamp on the receiving seat is dragged in a straight line after clamping the angle steel, the angle steel may get stuck on the guide clamp assembly. Therefore, in this device, the clamping seat can move up and down relative to the receiving seat, and the clamp on the clamping seat can swing back and forth relative to the clamping seat. In this way, when the clamp on the clamping seat clamps the angle steel and drags it, the clamp can swing back and forth at a certain angle, thereby ensuring that the angle steel will not be stuck on the guide clamp assembly, and ensuring that the angle steel can be stably transported on the guide clamp assembly.

[0017] Optionally, it also includes a supporting column and a flip cylinder, wherein the supporting column is arranged on one side of the receiving platform, one end of the guide clamp assembly is rotatably mounted on the supporting column through a circular axis, the flip cylinder is arranged on the supporting column, and the cylinder rod of the flip cylinder is hingedly matched with the guide clamp assembly.

[0018] The specific function of the support column is to install the guide clamp assembly, which is used to receive the angle steel after the opening and closing operation. When the guide clamp assembly on the support column completes the reception of an angle steel and needs to receive a new angle steel, the flip cylinder on the support column starts to operate, causing the guide clamp assembly on the support column to flip. After the angle steel in the guide clamp assembly flips out, the flip cylinder runs in the reverse direction, and the guide clamp assembly rotates back to the position before the flipping, and the guide clamp assembly begins to prepare to receive the next angle steel.

[0019] Optionally, it also includes a material receiving platform, the supporting column is arranged on one side of the supporting column, and the two sides of the supporting column are respectively a receiving platform and a material receiving platform.

[0020] The specific function of the material receiving table is to receive the angle steel that falls from the flipping assembly after the guide clamp assembly is flipped.

[0021] Optionally, a temporary storage buffer station is also included, and the temporary storage buffer station is arranged on one side of the pushing platform.

[0022] The purpose of the temporary storage buffer table is to place the angle steel materials that need to be opened and closed.

[0023] Optionally, it also includes a rotating support and a rotating shaft, the rotating shaft is rotatably mounted on the rotating support, a bearing arm is provided on the rotating shaft, an angle bracket is rotatably mounted on the bearing arm via the mounting shaft, a chain disk is provided on the mounting shaft, a chain disk is provided on the rotating shaft, and the chain disk on the mounting shaft and the chain disk on the rotating shaft are matched together through a chain.

[0024] Specifically in this device, the angle bracket has a V-shaped opening, and the angle bracket lifts the angle steel through its own V-shaped opening.

[0025] The function of the above-mentioned rotating support and rotating shaft is to transfer the angle steel raw materials from the temporary storage buffer table to the guide clamp assembly of the pushing platform. The chain plate on the mounting shaft and the chain plate on the rotating shaft are linked by a chain. The rotation of the mounting shaft drives the angle bracket to rotate, thereby ensuring that the opening of the angle bracket is always facing upwards.

[0026] The specific process of transferring the angle steel by the rotating shaft is as follows: first, the angle steel is located on the temporary storage buffer table. In the initial state, the angle bracket is located at the temporary storage buffer table. The angle steel on the temporary storage buffer table is moved into the angle bracket. Then the rotating shaft starts to rotate. The rotation of the rotating shaft drives the angle bracket to rotate together. When the angle bracket is transferred to one side of the pushing platform by the rotating shaft (the opening of the angle steel is always in an upward state during this process), the angle steel is supported by the guide clamp assembly on the pushing platform, and the angle bracket no longer supports the angle steel.

[0027] Optionally, a guide column is provided on the base platform, the extrusion drive member is installed on the guide column, a slide plate is slidably provided on the guide column, the pressing plate is provided on the slide plate, and the extrusion drive member is slidably matched with the slide plate.

[0028] The specific extrusion drive includes but is not limited to an electric cylinder, a gas cylinder or an oil cylinder. The extrusion drive is installed at one end of the guide post through a corresponding connection structure, and the slide plate is slidably installed on the guide post. The slide plate can slide along the guide post to ensure the stability of the slide plate when sliding, and ensure that the pressing plate can stably move up and down.

[0029] Optionally, the guide clamp assembly includes a base plate and a supporting roller, and the supporting roller is rotatably mounted on the base plate.

[0030] The specific bottom plate is an isosceles trapezoidal bottom plate. There are two rows of support rollers on the bottom plate, and the angle between the two rows of support rollers is 90 degrees, so that the angle steel can be guided quickly and stably.

[0031] Specifically in this device, the bottom plate on one side of the pushing platform is directly installed at the edge of the pushing platform, while the guide clamp assembly on one side of the receiving platform is rotatably installed on the supporting column through its own bottom plate.

[0032] The beneficial effects of the present invention are as follows: a pushing seat and a receiving seat are respectively arranged on both sides of the base, and a guide clamp assembly is arranged on both sides, and clamps are arranged on the pushing seat and the receiving seat, which can clamp the angle steel and then drag it to move on the guide clamp assembly, thereby realizing the continuous operation of angle steel transportation and opening and closing angles, and the angle steel opening and closing operation efficiency is higher.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0045] In the description of the present application, it should be noted that the terms used here are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0046] As attached Figures 1 to 8As shown, a device for opening and closing angles of angle steel 4 includes a base 2, an extrusion driving member 29, a base template 25 and a pressing template 26, wherein the base template 25 is arranged on the base 2, the extrusion driving member 29 is arranged on the base 2, and the pressing template 26 is arranged on the extrusion driving member 29. It also includes a pushing platform 1, a receiving platform 3 and a guide clamp assembly, wherein the pushing platform 1 and the receiving platform 3 are respectively located at the two ends of the base 2, a guide clamp assembly is arranged on one side of the pushing platform 1, a guide clamp assembly is arranged on one side of the receiving platform 3, and guide clamp assemblies are distributed on both sides of the base 2, a pushing seat 13 is slidably arranged on the pushing platform 1, a receiving seat 19 is arranged on the receiving platform 3, and clamps 9 are arranged on both the pushing seat 13 and the receiving seat 19.

[0047] The specific functions of this opening and closing angle device are as follows. First, the guide clamping assemblies located on both sides of the base 2 can be used to guide and clamp the angle steel 4. After the clamps 9 on the pushing seat 13 clamp the angle steel 4, the pushing seat 13 pushes the angle steel 4 to move toward the base 2. When the position where the angle steel 4 needs to be bent runs between the bottom template 25 and the pressing template 26, the extrusion driving member 29 drives the pressing template 26 to press down. The angle steel 4 completes the opening and closing angle under the clamping and extrusion of the bottom template 25 and the pressing template 26, and then the extrusion driving member 29 drives the pressing template 26 to move upward. At this time, the receiving seat 19 located on the receiving platform 3 moves toward the angle steel 4. After the clamps 9 on the receiving seat 19 clamp the angle steel 4, they drag the angle steel 4 away from the base 2, so that the angle steel 4 slides into the guide clamping assembly on one side of the receiving platform 3.

[0048] In summary, in this type of opening and closing angle device, a pushing seat 13 and a receiving seat 19 are respectively arranged on both sides of the base 2, and a guide clamp assembly is arranged on both sides. A clamp 9 is arranged on the pushing seat 13 and the receiving seat 19, which can clamp the angle steel 4 and then drag it to move on the guide clamp assembly, thereby realizing the continuous operation of conveying and opening and closing the angle of the angle steel 4, and the opening and closing angle operation efficiency of the angle steel 4 is higher.

[0049] Specifically, a placement groove 10 is further provided on one side of the pushing platform 1 .

[0050] As attached Figure 4 and 5 As shown, it also includes a lifting cylinder 24, which is arranged on both sides of the base 2, and a guide clamp assembly is arranged on the cylinder rod of the lifting cylinder 24.

[0051] Specifically, the lifting cylinders 24 located on both sides of the base 2 have the following functions: when the angle steel 4 needs to pass between the bottom template 25 and the pressing template 26, the cylinder rod of the lifting cylinder 24 extends, so that the guide clamp assembly on the lifting cylinder 24 contacts the angle steel 4, so that the angle steel 4 does not contact the bottom template 25, so that the bottom template 25 will not be worn during the process of dragging and conveying the angle steel 4. When the angle steel 4 needs to be opened and closed, the cylinder rod of the lifting cylinder 24 shortens, the guide clamp assembly on the lifting cylinder 24 moves down, the guide clamp assembly on the lifting cylinder 24 no longer contacts the angle steel 4, and the bottom template 25 holds the angle steel 4. When the pressing template 26 moves toward the bottom template 25, the opening and closing angle of the angle steel 4 can be achieved by squeezing the bottom template 25 and the pressing template 26.

[0052] As attached Figure 1 and 2 As shown, a guide rail 11 is provided on the pushing platform 1, and a pushing seat 13 is slidably matched with the guide rail 11 on the pushing platform 1, a rack 12 is provided on the pushing platform 1, and a pushing motor is provided on the pushing seat 13, and the shaft of the pushing motor is matched with the rack 12 on the pushing platform 1 through a gear, a guide rail 11 is provided on the receiving platform 3, and a receiving seat 19 is slidably matched with the guide rail 11 on the receiving platform 3, a rack 12 is provided on the receiving platform 3, and a receiving motor is provided on the receiving seat 19, and the shaft of the receiving motor is matched with the rack 12 on the receiving platform 3 through a gear.

[0053] The guide rail 11 and the rack 12 are used to ensure that the traction seat and the receiving seat 19 can move stably.

[0054] As attached Figure 3 , 6 As shown in 7, it also includes a clamping seat 20, a slide rail 30 is arranged on the receiving seat 19, a slider 31 is arranged on the clamping seat 20, the slider 31 and the slide rail 30 are slidably matched together, a clamping clamp 34 and a clamping cylinder are arranged on the receiving seat 19, the clamping cylinder and the clamping clamp 34 are matched together, a floating guide rod 35 is arranged on the clamping seat 20, and the floating guide rod 35 passes through the gap of the clamping clamp 34; the clamp 9 is rotatably installed in the groove 2001 of the clamping seat 20 through the central axis 32, and a damping buffer rod is arranged between the clamp 9 and the groove arm of the groove 2001.

[0055] Specifically, the clamping clamp 34 can play the role of clamping the floating guide rod 35, and can also play the role of guiding the floating guide rod 35. When the clamping clamp 34 clamps the floating guide rod 35, the clamping seat 20 cannot move up and down relative to the receiving seat 19 (i.e. float up and down), and when the clamping clamp 34 no longer clamps the floating guide rod 35, the clamping seat 20 is in a state of being able to move up and down relative to the receiving seat 19, and the role of the slide rail 30 and the slider 31 is to guide the up and down movement of the clamping seat 20, so as to avoid the clamping seat 20 from being sluggish during the up and down movement. In order to ensure that the clamping seat 20 does not exceed the limit position during the up and down sliding process, baffles can be set at the upper and lower ends of the push seat 13, and the baffles are used to block the slider 31, so that the slider 31 slides between the upper and lower baffles.

[0056] Specifically in this device, the slide rail 30 is perpendicular to the guide rail 11 on the receiving platform 3, the up and down movement direction of the clamping seat 20 is perpendicular to the sliding direction of the receiving seat 19, and the moving direction of the receiving seat 19 is the direction of the dragging angle steel 4.

[0057] In the present device, the clamp 9 is rotatably installed in the groove 2001 of the clamping seat 20 through the central axis 32, and the clamp 9 can swing back and forth in the groove 2001 around the central axis 32. At the same time, since a damping buffer rod is arranged between the clamp 9 and the groove wall of the groove 2001 (one end of the damping buffer rod is fixed in the groove wall of the groove 2001, and the other end of the damping buffer rod is not fixed by the clamp 9), damping buffer rods are distributed on both sides of the clamp 9. The damping buffer rods can play a buffering role for the clamp 9. The existence of the damping buffer rod can ensure that the clamp 9 will not touch the groove wall of the guide groove 2001. The specific swinging direction of the clamp 9 is perpendicular to the up and down lifting direction of the clamping seat 20.

[0058] The role of the above-mentioned use of the clamp seat 20 to elastically buffer the installation of the clamp 9 is as follows. First, after the angle steel 4 is processed by the opening and closing angle, the angle steel 4 is no longer in a straight line, but has a certain degree of bending or warping. Therefore, if the clamp 9 on the receiving seat 19 is dragged in a straight line after clamping the angle steel 4, the angle steel 4 may be stuck on the guide clamp assembly. Therefore, in this device, the clamp seat 20 can move up and down relative to the receiving seat 19, and the clamp 9 on the clamp seat 20 can swing back and forth relative to the clamp seat 20. In this way, when the clamp 9 on the clamp seat 20 clamps the angle steel 4 and drags it, the clamp 9 can swing back and forth at a certain angle up and down, left and right, so as to ensure that the angle steel 4 will not be stuck on the guide clamp assembly, and ensure that the angle steel 4 can be stably transported on the guide clamp assembly.

[0059] As attached Figure 3 and 8As shown, it also includes a supporting column 18 and a flip cylinder 17. The supporting column 18 is arranged on one side of the receiving platform 3. One end of the guide clamp assembly is rotatably mounted on the supporting column 18 through a circular shaft 36. The flip cylinder 17 is arranged on the supporting column 18, and the cylinder rod of the flip cylinder 17 is hingedly matched with the guide clamp assembly.

[0060] The specific function of the support column 18 is to install the guide clamp assembly, which is used to receive the angle steel 4 after the opening and closing operation. When the guide clamp assembly on the support column 18 completes the reception of an angle steel 4 and needs to receive a new angle steel 4, the flip cylinder 17 on the support column 18 starts to operate, so that the guide clamp assembly on the support column 18 starts to flip, and after the angle steel 4 in the guide clamp assembly flips out, the flip cylinder 17 runs in the reverse direction, and the guide clamp assembly rotates back to the position before the flipping, and the guide clamp assembly starts to prepare to receive the next angle steel 4.

[0061] As attached Figure 1 As shown, it also includes a material receiving platform 23, the support column 18 is arranged on one side of the support column 18, and the two sides of the support column 18 are the receiving platform 3 and the material receiving platform 23 respectively.

[0062] The specific function of the receiving platform 23 is to receive the angle steel 4 that falls out of the turning assembly after the guide clamp assembly is turned over.

[0063] As attached Figure 1 and 2 As shown, it also includes a temporary storage buffer table 14, which is arranged on one side of the pushing support platform 1.

[0064] The temporary storage buffer table 14 is used to place the angle steel 4 raw materials that need to be opened and closed.

[0065] As attached Figure 1 and 2 As shown, it also includes a rotating support 8 and a rotating shaft 7. The rotating shaft 7 is rotatably installed on the rotating support 8. A load-bearing arm 6 is provided on the rotating shaft 7. An angle bracket 16 is rotatably installed on the load-bearing arm 6 via a mounting shaft 15. A chain plate 5 is provided on the mounting shaft 15. The rotating shaft 7 is provided with a chain plate 5. The chain plate 5 on the mounting shaft 15 and the chain plate 5 on the rotating shaft 7 are matched together through a chain.

[0066] Specifically in this device, the angle bracket 16 has a V-shaped opening, and the angle bracket 16 supports the angle steel 4 through its own V-shaped opening.

[0067] The function of the above-mentioned rotating support 8 and rotating shaft 7 is to transfer the angle steel 4 raw material from the temporary storage buffer table 14 to the guide clamp assembly of the pushing support platform 1. The chain plate 5 on the mounting shaft 15 and the chain plate 5 on the rotating shaft 7 are linked by a chain. The rotation of the mounting shaft 15 drives the angle bracket 16 to rotate, thereby ensuring that the opening of the angle bracket 16 is always facing upwards.

[0068] The specific process of transporting the angle steel 4 by the rotating shaft 7 is as follows: first, the angle steel 4 is located on the temporary storage buffer table 14; in the initial state, the angle bracket 16 is located at the temporary storage buffer table 14; the angle steel 4 on the temporary storage buffer table 14 is moved into the angle bracket 16; and then the rotating shaft 7 starts to rotate; the rotation of the rotating shaft 7 drives the angle bracket 16 to rotate together; when the angle bracket 16 is transported to one side of the pushing platform 1 by the rotating shaft 7 (the front opening of the angle steel 4 is always in an upward state during this process), the angle steel 4 is supported by the guide clamp assembly on the pushing platform 1, and the angle bracket 16 no longer supports the angle steel 4.

[0069] As attached Figure 1 , 4 As shown in Figure 5, a guide column 28 is provided on the base 2, an extrusion drive member 29 is installed on the guide column 28, a slide plate 27 is slidably provided on the guide column 28, a pressing plate 26 is provided on the slide plate 27, and the extrusion drive member 29 and the slide plate 27 are slidably matched together.

[0070] The specific extrusion drive member 29 includes but is not limited to an electric cylinder, a cylinder or an oil cylinder. The extrusion drive member 29 is installed at one end of the guide post through a corresponding connection structure, and the slide plate 27 is slidably installed on the guide post 28. The slide plate 27 can slide along the guide post 28 to ensure the stability of the slide plate 27 when sliding, and ensure that the pressing plate 26 can stably move up and down.

[0071] As attached Figure 8 As shown, the guide clamp assembly includes a base plate 22 and a supporting roller 21 , and the supporting roller 21 is rotatably mounted on the base plate 22 .

[0072] Specifically, the bottom plate 22 is an isosceles trapezoidal bottom plate 22 , and there are two rows of support rollers 21 on the bottom plate 22 , and the angle between the two rows of support rollers 21 is 90 degrees, so that the angle steel 4 can be guided quickly and stably.
