For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] The utility model provides a novel cable tray forming machine unit.

[0030] Embodiment 1:

[0031] like Figure 1-3 As shown, it includes a U-shaped frame 1 and two L-shaped workbenches 2. Slide grooves 13 are provided on both sides of the top of the U-shaped frame 1. The bottom surface above the L-shaped workbench 2 is fixedly connected with a slide bar 24. The slide bar 24 is slidably connected inside the slide groove 13, so that the two L-shaped workbenches 2 are slidably connected to the two sides of the top of the U-shaped frame 1, respectively. The inner walls on both sides of the U-shaped frame 1 are fixedly connected with a first hydraulic cylinder 21. The output end of the first hydraulic cylinder 21 is fixedly connected to the L-shaped workbench 2. By extending and retracting the first hydraulic cylinder 21, the spacing between the two L-shaped workbenches 2 can be adjusted, so that trough-type cable trays of different widths can be pressed out. A second hydraulic cylinder 3 is fixedly connected to the bottom of the frame 1, and a bottom plate 31 is fixedly connected to the output end of the second hydraulic cylinder 3. The second hydraulic cylinder 3 can adjust the height of the bottom plate 31, so that trough-type cable trays of different depths can be pressed out. A plurality of support plates 32 are fixedly connected to both sides of the bottom plate 31. A plurality of tooth grooves 22 are provided at the bottom of the L-shaped workbench 2. The support plates 32 are inserted into the tooth grooves 22. When the distance between the two L-shaped workbench 2 changes, the setting of the support plates 32 can supplement the gap between the bottom plate 31 and the inner wall of the L-shaped workbench 2, thereby ensuring that the bottom surface of the pressed trough-type cable tray is flat;

[0032] One side of the U-shaped frame 1 is fixedly connected to a bracket 11, the top of the bracket 11 is fixedly connected to a third hydraulic cylinder 4, the output end of the third hydraulic cylinder 4 faces downward, the output end of the third hydraulic cylinder 4 is fixedly connected to a pressing plate 41, both sides of the pressing plate 41 are slidably connected to baffles 42, both sides of the pressing plate 41 are provided with positioning holes 411, one side of the baffle 42 is fixedly connected to a positioning rod 421, the positioning rod 421 is slidably inserted in the positioning hole 411, and when the trough-type cable tray is pressed, the baffle 42 can block the two side walls of the trough-type cable tray of the pressing plate 41. The baffle 42 is fixedly connected to the side wall of the baffle 42, and the screw 44 at the output end of the double-axis motor 43 is threadedly connected to the inside of the threaded barrel 45. The double-axis motor 43 drives the screw 44 to rotate inside the threaded barrel 45, thereby driving the two baffles 42 to move closer to or away from each other.

[0033] Furthermore, a support leg 12 is fixedly connected to the bottom of the U-shaped frame 1 for supporting the U-shaped frame 1 .

[0034] Specifically, the support leg 12 includes an adjustment cylinder 121, the internal thread of the adjustment cylinder 121 is connected to a support screw 122, and the bottom end of the support screw 122 is fixedly connected to a base 123. By rotating the support screw 122 in the adjustment cylinder 121, the length of the support leg 12 can be adjusted, thereby ensuring that all the support legs 12 can touch the ground.

[0035] Preferably, Figure 1-2 As shown, a transverse adjusting screw 5 is threadedly connected to the bracket 11, and one end of the adjusting screw 5 is rotatably connected to a limiting plate 51. When the metal plate material of the pressed trough type cable tray is placed on the top surface of the L-shaped workbench 2, the limiting plate 51 can limit one side of the metal plate, thereby facilitating the accurate placement of the metal plate to a suitable position. A plurality of guide rods 52 are fixedly connected to the side of the limiting plate 51 close to the adjusting screw 5, and the guide rods 52 are slidably connected in the bracket 11. A turntable 53 is fixedly connected to the end of the adjusting screw 5 away from the limiting plate 51. By rotating the turntable 53, the adjusting screw 5 rotates in the bracket 11, thereby the position of the limiting plate 51 can be adjusted.

[0036] Embodiment 2:

[0037] like Figure 1 As shown, on the basis of Example 1, the bottom of the tooth groove 22 is rotatably connected to a roller 23, and the roller 23 supports the L-shaped workbench 2. In the process of the first hydraulic cylinder 21 driving the L-shaped workbench 2 to move, the roller 23 rotates, thereby avoiding the problem of noise generated by friction between the L-shaped workbench 2 and the U-shaped frame 1.

[0038] Embodiment three:

[0039] Due to the restriction of the first hydraulic cylinder 21 and the slide bar 24 on the support plate 32, the bottom plate 31 cannot rise to be flush with the top surface of the L-shaped workbench 2, so the pressed trough-type cable tray is easily stuck between the two L-shaped workbenches 2 and is not easy to remove. Therefore, further improvements are made on the basis of the first or second embodiment, such as Figure 4 As shown, the shape of the bottom plate 31 is U-shaped, and the inside of the bottom plate 31 is fixedly connected to a fourth hydraulic cylinder 33, and the output end of the fourth hydraulic cylinder 33 is fixedly connected to a push plate 34. When the pressed trough-type cable tray is stuck between the two L-shaped workbenches 2, the push plate 34 is raised by extending the fourth hydraulic cylinder 33, so that the trough-type cable tray can be pushed out, thereby facilitating the removal.

[0040] Specifically, the inner walls on both sides of the bottom plate 31 are fixedly connected with support bars 35. When the push plate 34 descends into the U-shaped bottom plate 31, the support bars 35 support the bottom of the push plate 34. Therefore, during the stamping process, the pressure plate 41 presses down the metal sheet, and the fourth hydraulic cylinder 33 will not be subjected to the pressure of the pressure plate 41, thereby achieving the purpose of protecting the fourth hydraulic cylinder 33.

[0041] According to the working principle of the hydraulic cylinder, the first hydraulic cylinder 21, the second hydraulic cylinder 3, the third hydraulic cylinder 4 and the fourth hydraulic cylinder 33 in the above embodiments are equipped with oil tanks, oil pump hydraulic valves, actuators and other components for controlling the extension and retraction of the hydraulic cylinders. These components are all well-known technologies, so the components equipped with the hydraulic cylinders will not be described in detail in this application, and the components equipped with the hydraulic cylinders will not be reflected in the accompanying drawings.

[0042] The working principle of the utility model is as follows: when in use, according to the specifications of the trough-type cable tray to be pressed, the height of the bottom plate 31 is adjusted by telescoping the second hydraulic cylinder 3, so that the distance between the bottom plate 31 and the top surface of the L-shaped workbench 2 is adjusted to achieve the purpose of adjusting the depth of the pressed trough-type cable tray;

[0043] By extending and retracting the first hydraulic cylinder 21, the L-shaped workbench 2 is driven to slide on the U-shaped frame 1, so that the distance between the two L-shaped workbench 2 can be adjusted, thereby achieving the purpose of adjusting the width of the pressed trough type cable tray;

[0044] When the distance between the two L-shaped workbenches 2 needs to be adjusted, the dual-axis motor 43 needs to be started to adjust the distance between the two baffles 42 accordingly to ensure that the pressing plate 41 and the baffle 42 can cooperate with the L-shaped workbench 2 to press out a trough-type cable tray of corresponding width;

[0045] When the width and depth are adjusted, the metal sheet used to process the trough-type cable tray is placed above the two L-shaped workbenches 2. By extending the third hydraulic cylinder 4, the pressure plate 41 and the baffle 42 are lowered, so that the metal sheet is pressed between the two L-shaped workbenches 2, thereby pressing and forming the trough-type cable tray. After the pressing is completed, the pressure plate 41 is raised, and then the second hydraulic cylinder 3 and the fourth hydraulic cylinder 33 are extended to push the pressed trough-type cable tray upward.

[0046] Compared with the prior art, the present invention has the following beneficial effects:

[0047] 1. The second hydraulic cylinder 3 can adjust the height of the bottom plate 31, so that trough-type cable trays of different depths can be pressed out. By extending the first hydraulic cylinder 21, the distance between the two L-shaped workbenches 2 can be adjusted, so that trough-type cable trays of different widths can be pressed out. The dual-axis motor 43 drives the screw 44 to rotate inside the threaded barrel 45, so that the two baffles 42 can be driven to move closer to or away from each other, so as to achieve the purpose of adjusting the width of the pressing mold. The support plate 32 fills the gap between the bottom plate 31 and the L-shaped workbench 2 to ensure the flatness of the bottom surface of the pressed trough-type cable tray, so as to achieve the purpose of pressing trough-type cable trays of different widths and depths, and there is no need to change the mold, which is simple to operate and saves time and effort.

[0048] 2. By arranging baffles 42 on both sides of the pressing plate 41, when pressing the trough type cable tray, the baffles 42 can block the two side walls of the trough type cable tray of the pressing plate 41 to prevent the two side walls of the trough type cable tray from bending upwards of the pressing plate 41, thereby ensuring that the two side walls of the trough type cable tray are perpendicular to the bottom surface, and avoiding the problem of the trough type cable tray being stuck on the pressing plate 41, thereby improving practicality.

[0049] 3. By arranging a roller 23 below the tooth groove 22, the roller 23 supports the L-shaped workbench 2, and when the first hydraulic cylinder 21 drives the L-shaped workbench 2 to move, the roller 23 rotates, thereby avoiding the problem of noise generated by friction between the L-shaped workbench 2 and the U-shaped frame 1.

[0050] 4. By setting the bottom plate 31 into a U shape and arranging a fourth hydraulic cylinder 33 and a push plate 34 inside, after the metal sheet is pressed into a trough-type cable tray, the push plate 34 can be used to push the trough-type cable tray out from between the two L-shaped workbenches 2 when the fourth hydraulic cylinder 33 is extended, thereby facilitating the removal of the trough-type cable tray.

[0051] 5. By providing the support bar 35 , the support bar 35 supports the push plate 34 , so that during the stamping process, the pressing plate 41 presses down the metal plate, and the fourth hydraulic cylinder 33 will not be subjected to the pressure of the pressing plate 41 , thereby achieving the purpose of protecting the fourth hydraulic cylinder 33 .
