Description

Technical Field

[0001] This utility model relates to the technical field of cable tray processing, and in particular to a molded frame for a trough-type cable tray. Background Technology

[0002] Trough-type cable trays are trough-shaped components bent from a single sheet of steel. Trough-type cable trays are generally manufactured using a molding process for the frame. Existing technologies disclose various molding processes for trough-type cable trays. For example, Chinese utility model patent CN219464541U discloses a molding frame for a trough-type cable tray. This molding frame includes a support base, a forming device, a molding device, and a control panel. The support base has an anti-slip support rod on its underside, a rubber resistance-increasing disc on its underside, and a resistance-increasing rubber strip on its underside. A gantry frame is mounted on the support base, and the inner side of the gantry frame has… The forming device has a displacement groove on a gantry frame, and a molding device is installed on the gantry frame. The assembly block of the molding device is fixed to the gantry frame by bolts. The front of the support base has an assembly panel, and the assembly panel of the support base has a control panel. Because the forming device of this utility model is equipped with a displacement cylinder, during the operation, the user can move the device a corresponding distance according to the processing dimensions of the trough cable tray, thereby forming and die-casting the material to be processed. In addition, the molding device of this equipment is equipped with a replaceable pressure plate, and this equipment can process different models of trough cable trays.

[0003] However, the aforementioned molding processing device lacks the structure and function to fold the edges of the cable tray, so it can only mold straight, unfolded trough-type cable trays, resulting in significant limitations. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a molded frame for a straight, flanged trough-type cable tray that can be molded, with fewer limitations.

[0005] This utility model discloses a molding frame for a trough-type cable tray, comprising a frame and a base plate. The base plate is horizontally installed at the lower part of the frame and is used to hold the sheet metal. It also includes a central pressing mechanism, two side plates, two flange blocks, two limiting components, and two push cylinders. The central pressing mechanism is installed in the upper middle of the frame, facing the base plate vertically, and is used to press the middle of the sheet metal. The lower ends of the two side plates are hinged to the left and right sides of the base plate. The two flange blocks are rotatably installed on the upper ends of the two side plates, and slots are provided on the opposite side walls of the two flange blocks to clamp the left and right edges of the sheet metal. The slots of the two flange blocks are horizontally positioned. The two limiting components are installed on the outer sides of the two side plates to keep the two flange blocks horizontal. The outer ends of the two push cylinders are rotatably connected to the left and right outer ends of the base plate, and the inner ends of the two push cylinders are rotatably connected to the two flange blocks. During operation, the two push cylinders... The shrinking mechanism places the two side plates flat on the left and right sides of the base plate. The sheet material is placed on the inner walls of the base plate and the two side plates, and the left and right edges of the sheet material are inserted into the slots of the two flange blocks. The slots of the two flange blocks clamp the edge ends of the sheet material. The middle pressing mechanism descends to press the middle of the sheet material onto the base plate. The two push cylinders extend simultaneously to push the two flange blocks and the two side plates to flip and stand upright. The inner walls of the two side plates press the left and right sides of the sheet material upward onto the left and right side walls of the middle pressing mechanism, completing the molding of the left and right upright plates of the cable tray. At the same time, during the process of flipping and standing up the two side plates, the two flange blocks flip and stand up simultaneously. The two limiting components keep the slots of the two flange blocks in a horizontal state, so that the two flange blocks flip relative to the ends of the two side plates. The slots of the two flange blocks bend the edges of the left and right upright plates of the cable tray outward to form flanges. It can mold and process straight trough-type cable trays with flanges, with few limitations.

[0006] Preferably, it also includes two slides, which are slidably mounted on the left and right sides of the base plate. The lower ends of the two side plates are rotatably mounted on the middle of the two slides, and the outer ends of the two push cylinders are rotatably mounted on the outer ends of the two slides. The two slides slide relative to each other on the base plate, thereby adjusting the distance between the two side plates, realizing the molding process of cable trays of different widths, and improving versatility.

[0007] Preferably, the limiting component includes a lower crossbar, an upper crossbar, and multiple connecting rods. The lower crossbar is horizontally mounted on the slide table, and the upper crossbar is horizontally mounted on the flange block. The lower ends of the multiple connecting rods are rotatably connected to the lower crossbar, and the upper ends of the multiple connecting rods are rotatably connected to the upper crossbar. The multiple connecting rods are arranged in parallel. The lower crossbar, upper crossbar, and multiple connecting rods form a parallelogram. Because the lower crossbar and upper crossbar are arranged horizontally, they horizontally limit the flange block, ensuring that the groove of the flange block remains horizontal when the side plate and the flange block are flipped and rotated, thus improving practicality.

[0008] Preferably, it also includes two rollers, each with a slot that communicates with a slot. The two rollers are rotatably mounted on the two flanged blocks via brackets, and the surfaces of the two rollers rub against the flanges of the cable tray. When loading and placing the sheet material, the left and right edges of the sheet material are inserted into the slots of the two flanged blocks, and the two rollers rotate and rub against the sheet material to transport it backward, improving the feeding efficiency. After the sheet material is formed by pressing, the two rollers reverse and rub against the sheet material to transport it forward, achieving automatic unloading and good practicality.

[0009] Preferably, it also includes multiple limiting bosses, with multiple limiting bosses installed on both slides, which limit and block the inner walls of the two side plates; by setting multiple limiting bosses to limit and block the two side plates that are flipped upright, the two side plates are prevented from flipping excessively, thereby improving the stability of the two side plates.

[0010] Preferably, the central pressing mechanism includes a second push cylinder, a mounting base, multiple support rods, two angular pressure blocks, and a third push cylinder. The fixed end of the second push cylinder is installed in the upper middle of the frame. The mounting base is installed at the lower end of the piston rod of the second push cylinder. The inner ends of the multiple support rods are rotatably mounted on the end face of the mounting base, and the outer ends of the multiple support rods are rotatably connected to the two angular pressure blocks. The two angular pressure blocks are arranged opposite each other on the left and right sides of the mounting base. The two ends of the third push cylinder are connected to the two angular pressure blocks respectively. The third push cylinder extends and retracts to adjust the distance between the two angular pressure blocks, thereby cooperating with the two side plates to achieve the molding processing of cable trays of different widths. When the third push cylinder extends and retracts, the multiple support rods open or close adaptively. The piston rod of the second push cylinder extends downward, pushing the mounting base down, so that the mounting base drives the two angular pressure blocks down through the multiple support rods, so that the two angular pressure blocks press the middle of the plate onto the base plate. The outer walls of the two angular pressure blocks cooperate with the two side plates to mold the left and right upright plates of the cable tray, which has good practicality.

[0011] Preferably, it also includes multiple gears, which are respectively installed on the inner ends of multiple support rods, with two gears on the left and right sides meshing; by setting multiple gears, the two support rods arranged on the left and right sides can rotate synchronously, thereby improving the synchronization of the two angular pressure blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, the two push cylinders retract to flatten the two side plates on the left and right sides of the base plate. The plate is placed on the inner walls of the base plate and the two side plates, and the left and right edges of the plate are inserted into the slots of the two flange blocks. The slots of the two flange blocks clamp the edge ends of the plate. The middle pressing mechanism descends to press the middle of the plate onto the base plate. The two push cylinders extend simultaneously to push the two flange blocks and the two side plates to flip upwards and stand upright. The inner walls of the two side plates press the left edge of the plate upwards and stand upright. The two right sides are pressed upwards and folded onto the left and right side walls of the central pressing mechanism to complete the molding of the left and right upright plates of the cable tray. At the same time, during the process of the two side plates flipping and standing up, the two flange blocks flip and stand up synchronously. The two limiting components keep the slots of the two flange blocks in a horizontal state, so that the two flange blocks flip relative to the ends of the two side plates. This causes the slots of the two flange blocks to bend the edges of the left and right upright plates of the cable tray outwards to form flanges. This process can mold straight trough-type cable trays with flanges, with few limitations. Attached Figure Description

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a molding frame for a trough-type cable tray includes a frame 1 and a base plate 2. The base plate 2 is horizontally installed at the lower part of the frame 1 and is used to hold the sheet metal. It also includes a central pressing mechanism 3, two side plates 4, two flanged blocks 5, two limiting components 6, and two push cylinders 7. The central pressing mechanism 3 is installed in the upper middle part of the frame 1, and is vertically opposite to the base plate 2. The central pressing mechanism 3 is used to press the middle of the sheet metal. The lower ends of the two side plates 4 are hinged to the left and right sides of the base plate 2. The two flanged blocks 5 are rotatably installed on the upper ends of the two side plates 4, and slots are provided on the opposite side walls of the two flanged blocks 5. Two slots are used to clamp the left and right edges of the plate. The slots of the two flange blocks 5 are horizontally set. Two limiting components 6 are respectively installed on the outer side of the two side plates 4. The two limiting components 6 keep the two flange blocks 5 in a horizontal state. The outer ends of the two push cylinders 7 are respectively rotatably connected to the left and right outer ends of the base plate 2, and the inner ends of the two push cylinders 7 are respectively rotatably connected to the two flange blocks 5. It also includes two rollers 19. The two flange blocks 5 are provided with slots. The slots are connected to the slots. The two rollers 19 are respectively rotatably installed on the two flange blocks 5 through brackets. The wheel surfaces of the two rollers 19 are in frictional contact with the flange of the cable tray.

[0023] During operation, the two push cylinders 7 retract, flattening the two side plates 4 on the left and right sides of the base plate 2. The sheet material is placed on the inner walls of the base plate 2 and the two side plates 4, with the left and right edges of the sheet material inserted into the slots of the two flange blocks 5. The two rollers 19 rotate and rub against the sheet material, conveying it backward to achieve sheet material loading. The middle pressing mechanism 3 descends, pressing the middle of the sheet material onto the base plate 2. The two push cylinders 7 extend synchronously, pushing the two flange blocks 5 and the two side plates 4 upward to flip and stand upright. The inner walls of the two side plates 4 press the left and right sides of the sheet material upward to the middle pressing mechanism. On the left and right side walls of the clamping mechanism 3, the left and right upright plates of the cable tray are molded. At the same time, during the process of the two side plates 4 flipping and standing up, the two flange blocks 5 flip and stand up synchronously. The two limiting components 6 keep the slots of the two flange blocks 5 in a horizontal state, so that the two flange blocks 5 flip relative to the ends of the two side plates 4, so that the slots of the two flange blocks 5 bend the edges of the left and right upright plates of the cable tray outward to form flanges. It can mold and process straight trough-type cable trays with flanges with little limitation. After the plate is molded and formed, the two rollers 19 reverse and rub the plate to transport the plate forward, realizing automatic unloading.

[0024] Example 2

[0025] like Figures 1 to 4 As shown, based on Embodiment 1, it also includes two slides 8, which are slidably mounted on the left and right sides of the base plate 2. The lower ends of the two side plates 4 are rotatably mounted on the middle of the two slides 8, and the outer ends of the two push cylinders 7 are rotatably mounted on the outer ends of the two slides 8. The limiting assembly 6 includes a lower crossbar 9, an upper crossbar 10, and multiple connecting rods 11. The lower crossbar 9 is horizontally mounted on the slides 8, and the upper crossbar 10 is horizontally mounted on the flange block 5. The lower ends of the multiple connecting rods 11 are rotatably connected to the lower crossbar 9, and the upper ends of the multiple connecting rods 11 are rotatably connected to the upper crossbar 10. The multiple connecting rods 11 are arranged in parallel. It also includes multiple limiting bosses 12. Multiple limiting bosses 12 are installed on both slides 8, and the multiple limiting bosses 12 limit and block the inner walls of the two side plates 4.

[0026] Two sliding tables 8 slide relative to each other on the base plate 2, thereby adjusting the distance between the two side plates 4 to achieve molding processing of cable trays of different widths and improve versatility. The lower crossbar 9, the upper crossbar 10 and multiple connecting rods 11 form a parallelogram. Since the lower crossbar 9 and the upper crossbar 10 are arranged horizontally, the flange block 5 is horizontally limited, so that when the side plate 4 and the flange block 5 are flipped and rotated, the slot of the flange block 5 always remains horizontal. By setting multiple limiting bosses 12, the two side plates 4 that are flipped and erected are limited and blocked, so as to avoid the two side plates 4 from over-flipping and improve the stability of the two side plates 4.

[0027] Example 3

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, based on Embodiment 1, the central pressing mechanism 3 includes a second push cylinder 13, a mounting base 14, multiple support rods 15, two angular pressure blocks 16, and a third push cylinder 17. The fixed end of the second push cylinder 13 is installed in the upper middle of the frame 1. The mounting base 14 is installed at the lower end of the piston rod of the second push cylinder 13. The inner ends of the multiple support rods 15 are respectively rotatably installed on the end face of the mounting base 14. The outer ends of the multiple support rods 15 are respectively rotatably connected to the two angular pressure blocks 16. The two angular pressure blocks 16 are arranged opposite each other on the left and right sides of the mounting base 14. The two ends of the third push cylinder 17 are respectively connected to the two angular pressure blocks 16. It also includes multiple gears 18, which are respectively installed on the inner ends of the multiple support rods 15. The two gears 18 on the left and right sides mesh with each other.

[0029] The extension and retraction of the third push cylinder 17 adjusts the distance between the two angular pressure blocks 16, thereby cooperating with the two side plates 4 to achieve the molding process of cable trays of different widths. When the third push cylinder 17 extends and retracts, multiple support rods 15 open or close adaptively. By setting multiple gears 18, the two support rods 15 arranged on the left and right sides rotate synchronously, improving the synchronization of the two angular pressure blocks 16. The piston rod of the second push cylinder 13 extends downward, pushing the mounting base 14 down, so that the mounting base 14 drives the two angular pressure blocks 16 down through multiple support rods 15, so that the two angular pressure blocks 16 press the middle of the plate onto the base plate 2. The outer walls of the two angular pressure blocks 16 cooperate with the two side plates 4 to mold the left and right upright plates of the cable tray.

[0030] like Figures 1 to 6As shown, the present invention relates to a molded frame for a trough-type cable tray. During operation, firstly, two push cylinders 7 retract, flattening two side plates 4 on the left and right sides of the base plate 2.

Two rollers 19 rotate, rubbing against the sheet material to transport it backward, completing the loading process. The slots of the two flange blocks 5 clamp the edges of the sheet material. Then, the central pressing mechanism 3 descends, pressing the center of the sheet material onto the base plate 2. Next, the two push cylinders 7 simultaneously extend, pushing the two flange blocks 5 and the two side plates 4 upward, causing them to flip and stand upright. The inner wall of plate 4 presses the left and right sides of the plate upwards onto the left and right side walls of the central pressing mechanism 3, completing the molding of the left and right upright plates of the cable tray. At the same time, during the process of the two side plates 4 flipping and standing up, the two flange blocks 5 flip and stand up simultaneously. The two limiting components 6 keep the slots of the two flange blocks 5 in a horizontal state, so that the two flange blocks 5 flip relative to the ends of the two side plates 4, so that the slots of the two flange blocks 5 bend the edges of the left and right upright plates of the cable tray outwards to form flanges. Finally, the molding is completed, the central pressing mechanism 3 rises and disengages from the cable tray, and the two rollers 19 reverse and rub the plate to convey the plate forward for feeding.
