Detailed Implementation

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] like Figures 1 to 3 As shown, this utility model proposes a steel bar cutting device for water conservancy and hydropower construction, which includes:

[0036] The operating table 100 has a feeding port 101 on its surface;

[0037] The shearing assembly includes a bracket 110, the lower end of which is fixedly mounted on the table surface of the operating table 100. A telescopic cylinder 111 is mounted on the bracket 110, and a cutting blade 112 is mounted on the shaft end of the telescopic cylinder 111. A matching card seat 102 is mounted on the table surface of the operating table 100, and the cutting blade 112 cooperates with the card seat 102.

[0038] The unloading assembly works in conjunction with the shearing assembly to unload the cut steel bars from the operating table 100. The unloading assembly includes an L-shaped plate 120 rotatably installed in the discharge port 101. The surface of the L-shaped plate 120 slides in contact with the steel bars. Several cylinders 103 are installed at intervals on one side of the discharge port 101 to drive the L-shaped plate 120 to rotate. The shaft end of the cylinder 103 cooperates with the L-shaped plate 120. A discharge port 104 is opened on one side of the operating table 100. The discharge port 104 is located below the discharge port 101. A guide plate 105 is connected between the discharge port 104 and the discharge port 101.

[0039] In this embodiment, the shearing assembly shears the reinforcing bars using a common stamping cutting method. Its principle is the same as that of commonly available hydraulic shears. The telescopic cylinder 111 is a hydraulic cylinder, and the cutting blade 112 and the clamping seat 102 also use existing technology. The clamping seat 102 has a V-shaped groove. After the reinforcing bar 200 passes through the V-shaped groove, it is placed in the V-shaped groove. The V-shaped groove serves to fix and limit the movement, improving the stability of the reinforcing bar during the shearing process.

[0040] Because the stamping and cutting method is used, the mechanical strength requirements of the device as a whole are relatively high. In this embodiment, the operating table 100 and the support 110 are both made of metal. Their structure is similar to that of the machine tool operating table. The operating table 100 and the support 110 are relatively thick and heavy, which helps to ensure the overall stability during the cutting process.

[0041] The L-shaped plate 120 is installed in the discharge port 101. Its cross-section is L-shaped, including a bottom plate and a side plate. The upper surface of the bottom plate is flush with the table surface of the operating table 100. At this time, the cylinder 103 is in the retracted state. The width of the discharge port 101 is greater than the width of the L-shaped plate 120, so as to facilitate the rotation of the L-shaped plate 120 in the discharge port 101 and the unloading of the steel bars.

[0042] A guide plate 105 is connected between the discharge port 104 and the discharge port 101. In this embodiment, the guide plate 105 is inclinedly arranged inside the operating table 100. When the steel bar is unloaded from the L-shaped plate 120, it falls onto the guide plate 105. Under the action of the guide plate 105, it can quickly slide down to the discharge port 104 and collect. It should be noted that in this embodiment, the discharge port 101 is opened on the side of the operating table 100 away from the operator, which is conducive to protecting the personal safety of the operator.

[0043] In the initial state, the cutting blade 112 is above the holder 102, and there is a gap between the cutting blade 112 and the holder 102.

[0044] Please refer to Figure 1 and Figure 2 In use, in the initial state, one end of the steel bar 200 to be cut is passed through the V-shaped groove on the card holder 102. After the steel bar 200 passes through the V-shaped groove of the card holder 102, its surface slides into contact with the upper surface of the bottom plate of the L-shaped plate 120, pushing the steel bar 200 to be cut to continue moving. When the length of the steel bar on the side of the V-shaped groove close to the L-shaped plate 120 reaches the set requirement, the movement of the steel bar 200 to be cut is stopped.

[0045] The telescopic cylinder 111 is extended, and the cutting blade 112 moves down close to the mounting base 102. After the cutting blade 112 contacts the upper surface of the steel bar 200 to be cut, it continues to move down. Under the shearing action of the cutting blade 112, the steel bar 200 to be cut is cut off, thus completing the steel bar cutting work.

[0046] The control cylinder 103 extends, and the cylinder 103 pushes the L-shaped plate 120 to rotate toward the discharge port 101. The bottom plate of the L-shaped plate 120 tilts downward, and the cut steel bars slide from the bottom plate of the L-shaped plate 120 into the discharge port 101. Under the action of the guide plate 105, they slide out through the discharge port 104, completing the collection of steel bars.

[0047] The unloading process does not require manual handling of steel bars, which makes the processing safer and also effectively reduces the workload of workers, resulting in high work efficiency.

[0048] like Figures 1 to 6 As shown in one embodiment of the steel bar cutting device for water conservancy and hydropower construction according to this utility model,

[0049] A first eccentric wheel 106 and a second eccentric wheel 107 are rotatably connected on the surface of the operating table 100. The first eccentric wheel 106 and the second eccentric wheel 107 are respectively set on both sides of the bracket 110. A clamping block 108 is fixedly connected on the surface of the operating table 100. The clamping block 108 cooperates with the first eccentric wheel 106, and the second eccentric wheel 107 cooperates with the L-shaped plate 120.

[0050] There is a gap between the clamping block 108 and the first eccentric wheel 106, and there is a gap between the second eccentric wheel 107 and the L-shaped plate 120. The reinforcing bar passes through the gap between the clamping block 108 and the first eccentric wheel 106 and the gap between the second eccentric wheel 107 and the L-shaped plate 120 in sequence. The surfaces of the clamping block 108, the first eccentric wheel 106, the second eccentric wheel 107, and the L-shaped plate 120 all abut against the surface of the reinforcing bar.

[0051] In this embodiment, both the first eccentric wheel 106 and the second eccentric wheel 107 are fixedly connected to a rotating handle, which makes it convenient for workers to rotate the first eccentric wheel 106 and the second eccentric wheel 107.

[0052] The cooperation between the clamping block 108 and the first eccentric wheel 106, and between the second eccentric wheel 107 and the side plate of the L-shaped plate 120, serves to fix the steel bar 200 to be cut, which helps to ensure the stability of the steel bar when shearing it.

[0053] Please refer to Figure 1 and Figure 2 In use, the steel bar 200 to be cut is passed sequentially through the gap between the clamping block 108 and the first eccentric wheel 106, the clamping seat 102, and the gap between the second eccentric wheel 107 and the L-shaped plate 120. The first eccentric wheel 106 and the second eccentric wheel 107 are rotated so that the side walls of the first eccentric wheel 106 and the second eccentric wheel 107 contact and squeeze the steel bar 200 to be cut, thereby quickly clamping and fixing the steel bar 200 to be cut, making the cutting process safer. After the steel bar 200 to be cut is cut, the first eccentric wheel 106 and the second eccentric wheel 107 are rotated in the opposite direction to quickly release the steel bar from the clamp. It is very convenient to use.

[0054] It should be noted that the cooperation between the clamping block 108 and the first eccentric wheel 106, and between the second eccentric wheel 107 and the side plate of the L-shaped plate 120, only serves to fix the steel bar 200 to be cut. The force is not too great. The use of eccentric wheels can quickly achieve clamping and release, which is very convenient to use.

[0055] In addition, when the first eccentric wheel 106 and the second eccentric wheel 107 come into contact with and rotate the steel bar 200 to be cut, the steel bar 200 to be cut may move slightly. This error is acceptable for construction. Of course, some redundancy can be reserved in advance to ensure the accuracy of the length of the steel bar to be cut.

[0056] Connecting blocks 121 are symmetrically fixed to the side of the L-shaped plate 120 near the cylinder 103. The shaft end of the cylinder 103 passes between the two connecting blocks 121. Sliding grooves 122 are provided on both connecting blocks 121. A sliding shaft 123 is installed on the shaft end of the cylinder 103. The sliding shaft 123 extends outward from the sliding groove 122 and slides in contact with the inner wall of the sliding groove 122.

[0057] L-shaped plate 120 is fixedly connected to a limit block 124 on the side near cylinder 103, and the limit block 124 abuts against the surface of operating table 100.

[0058] The limiting block 124 serves as a support and limiter. When the second eccentric wheel 107 squeezes the steel bar 200 to be cut, the limiting block 124 abuts against the table surface of the operating table 100, thereby providing a firm support for the L-shaped plate 120 and ensuring the effect of clamping and fixing the steel bar.

[0059] In addition, a stop device for controlling the length of the reinforcing bar is installed on the L-shaped plate 120. The stop device cooperates with the cutting blade 112. The L-shaped plate 120 is provided with a number of fixing holes 125 spaced apart along the length direction. The stop device is threadedly connected to one of the fixing holes 125.

[0060] In this embodiment, the blocking device includes a support block 130. The support block 130 has a through hole 131 along the length of the L-shaped plate 120. An adjusting rod 132 is inserted into and slidably connected to the through hole 131. The two ends of the adjusting rod 132 extend freely after passing through the through hole 131. The end of the adjusting rod 132 near the cutting blade 112 passes through the through hole 131 and is fixedly connected to a stop plate 133. The side wall of the stop plate 133 near the cutting blade 112 abuts against the end of the reinforcing bar 200 to be cut.

[0061] In this embodiment, the shape of the stop plate 133 includes a square plate, and the lower surface of the stop plate 133 slides in contact with the surface of the L-shaped plate 120.

[0062] In addition, the support block 130 is provided with a threaded hole 134, which is connected to the through hole 131. A wing bolt 135 is threadedly connected to the threaded hole 134. One end of the wing bolt 135 near the through hole 131 passes through the threaded hole 134 and abuts against the adjusting rod 132. In this embodiment, the wing bolt 135 serves to fix the adjusting rod 132.

[0063] In this embodiment, the support block 130 is provided with a connecting hole 136, a connecting bolt 137 is inserted into the connecting hole 136, and a matching thread is provided in the fixing hole 125. The connecting bolt 137 is threadedly connected to the fixing hole 125, which serves to fix the support block 130.

[0064] By installing the support block 130 on different fixing holes 125, the distance between the support block 130 and the cutting blade 112 can be adjusted in a wide range and quickly, thereby adjusting the length of the cut steel bar. Loosening the wing bolt 135 releases the fixation of the adjusting rod 132, and sliding the adjusting rod 132 adjusts the position of the stop plate 133, which can precisely adjust the length of the cut steel bar. With the cooperation of the fixing hole 125 and the stop device, steel bars of different lengths can be cut to meet the needs of construction and have strong adaptability.

[0065] A push-button switch 109 is fixedly installed on the control panel 100. The push-button switch 109 is electrically connected to the telescopic cylinder 111 and the air cylinder 103 respectively. The operator can control the telescopic cylinder 111 and the air cylinder 103 by pressing the button on the push-button switch 109, which is very convenient to use.

[0066] Before use, select the appropriate fixing hole 125 according to the cutting length requirement, fix the support block 130 with the connecting bolt 137, loosen the wing bolt 135 to release the fixing of the adjusting rod 132, slide the adjusting rod 132 to adjust the position of the stop plate 133 so that the distance between the stop plate 133 and the cutting blade 112 is the cutting length.

[0067] In use, in the initial state, one end of the steel bar 200 to be cut is passed through the V-groove on the clamping seat 102 and the end is made to abut against the stop plate 133. The first eccentric wheel 106 and the second eccentric wheel 107 are rotated so that the side walls of the first eccentric wheel 106 and the second eccentric wheel 107 respectively come into contact with and squeeze the steel bar 200 to be cut, thereby quickly clamping and fixing the steel bar 200 to be cut.

[0068] The telescopic cylinder 111 extends by controlling the button switch 109, and the cutting blade 112 moves down. Under the shearing action of the cutting blade 112, the steel bar 200 to be cut is cut off, thus completing the cutting work of the steel bar 200 to be cut.

[0069] The first eccentric wheel 106 and the second eccentric wheel 107 are rotated in the opposite direction to release the fixing of the steel bar. The cylinder 103 is extended by the button switch 109. Under the action of the cylinder 103, the sliding shaft 123 slides relative to the sliding groove 122. The L-shaped plate 120 rotates, causing the steel bar to slide off the L-shaped plate 120 to the guide plate 105. Under the action of the slope of the guide plate 105, it slides down to the discharge port 104 to collect. The unloading is convenient, fast and safe, does not consume the physical strength of workers and has high work efficiency.

[0070] After unloading is completed, the telescopic cylinder 111 and cylinder 103 are reset by the button switch 109, the cutting blade 112 moves upward and resets, and the L-shaped plate 120 rotates in the opposite direction and resets, in preparation for the next cutting.

[0071] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
