Description
Technical Field
[0001] This utility model belongs to the field of steel shearing and processing technology, specifically a fixed-length shearing device for steel processing. Background Technology
[0002] A fixed-length shearing device is a mechanical device that can precisely cut materials such as wires, pipes, and plates to a preset length. It is widely used in many industries such as metallurgy, machinery manufacturing, construction, packaging, and plastics processing. Its core function is to ensure that the material length is consistent each time it is cut through automated or semi-automated control, thereby improving production efficiency and material utilization. However, when cutting steel, existing fixed-length shearing devices require workers to manually measure the length between the steel and the cutting groove before cutting. Each cut requires measurement, which affects cutting efficiency and is prone to measurement errors, resulting in significant deviations in the cut length of the steel. Utility Model Content
[0003] To overcome the above-mentioned defects, this utility model provides a fixed-length shearing device for steel processing, which solves the problem that when performing fixed-length shearing on steel, workers need to manually measure the length between the steel and the blade groove before shearing. Each shearing requires measurement, which affects cutting efficiency and is prone to measurement errors, resulting in a large deviation in the sheared length of the steel.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a fixed-length shearing device for steel processing, comprising a processing table, a T-shaped groove symmetrically provided on one side of the top of the processing table, three slots provided between two T-shaped grooves on the top of the processing table, a T-shaped slider slidably connected through the T-shaped groove, a sliding seat fixedly connected to the top of the T-shaped slider, a limiting groove provided on the opposite side of the two sliding seats, a sliding strip slidably connected through the limiting groove, a baffle fixedly connected between the two sliding strips, a locking strip fixedly installed at the bottom of the baffle, the locking strip corresponding to the position of the slot, locking blocks fixedly installed on both sides of the top of the baffle, mounting protrusions fixedly installed on the top of the two sliding seats, a rotating locking plate rotatably connected to the surface of the mounting protrusion, one side of the rotating locking plate corresponding to the position of the locking block.
[0005] As a further embodiment of this utility model: an electric lifting frame is fixedly installed at the center of each side of the processing table, a top seat is fixedly installed between the tops of the two electric lifting frames, a shearing blade is fixedly installed at the bottom of the top seat, and connecting plates are fixedly installed on both sides of the top of the shearing blade.
[0006] As a further embodiment of this utility model: connecting rods are slidably connected through both ends of the connecting plate, and a lower pressure plate is fixedly connected to the bottom of the two connecting rods, with the lower pressure plate being lower than the cutting edge of the shearing blade. A compression spring is provided on the surface of the connecting rod located between the connecting plate and the lower pressure plate.
[0007] As a further embodiment of this utility model: a knife groove is provided at the center of the top of the processing table, and the knife groove corresponds to the position of the shearing knife.
[0008] As a further embodiment of this utility model: a rectangular groove is provided on the side of the top of the processing table away from the baffle, and a motor is fixedly installed on the surface of the processing table located outside the rectangular groove.
[0009] As a further embodiment of this utility model: two rollers are rotatably connected between the inner walls of the rectangular groove via bearings, and one of the rollers is fixedly connected to the output end of the motor. A conveyor belt is sleeved on the surface of the two rollers, and limit blocks are fixedly installed on both sides of the top of the rectangular groove.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This steel processing fixed-length shearing device, by setting a sliding bar and a locking bar, allows for adjustment of the shearing length when the rotating plate is rotated out of the locking block, the baffle is lifted, and the locking bar is disengaged from the locking groove. At this time, the sliding bar slides in the limiting groove, preventing the baffle from disengaging from the sliding seat. Then, the baffle is pulled to move the sliding bar to another locking groove. When it reaches the position of the other locking groove, the baffle is pressed down, allowing the locking bar to be inserted into the locking groove. Finally, the rotating plate is rotated and snapped into the surface of the locking block, fixing the baffle at the top of the locking groove. This completes the adjustment of the shearing length and avoids large deviations in the steel length when cutting steel multiple times.
[0012] 2. The fixed-length shearing device for steel processing, by setting up a clamping spring and a lower pressure plate, when the steel is in the processing area, controls the electric lifting frame to move the top seat to move the shearing blade down to shear the steel. Before the shearing blade contacts the surface of the steel, the lower pressure plate presses and fixes the two sides of the steel. As the shearing blade moves down continuously, the clamping spring is compressed, causing the lower pressure plate to press the two sides of the steel, so that the two sides of the steel will not warp or deform when the steel is sheared by the shearing blade.

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a fixed-length shearing device for steel processing, including a processing table 1. T-slots 16 are symmetrically arranged on one side of the top of the processing table 1. Three slots 14 are arranged on the top of the processing table 1 between two T-slots 16. T-slider 17 is slidably connected through the T-slots 16. A sliding seat 10 is fixedly connected to the top of the T-slider 17. By providing the slots 14, the three slots 14 allow the baffle 12 to be fixed above the slots 14 by the snap-fit strip 15, thereby enabling the baffle 12 to control the shearing length of the steel and achieve precise control of the shearing length.
[0019] Each of the two sliding seats 10 has a limiting groove 11 on one side opposite to the other. A sliding strip 13 is slidably connected through the limiting groove 11. A baffle 12 is fixedly connected between the two sliding strips 13. A snap-fit strip 15 is fixedly installed at the bottom of the baffle 12, and the snap-fit strip 15 corresponds to the position of the snap-fit groove 14. By providing the limiting groove 11, the baffle 12 drives the sliding strip 13 to slide in the limiting groove 11, so that the baffle 12 will not detach from the sliding seat 10 when it drives the snap-fit strip 15 to move out of the snap-fit groove 14.
[0020] The baffle 12 is fixedly installed with snap-fit blocks 20 on both sides of the top. The two sliding seats 10 are fixedly installed with mounting protrusions 18. The mounting protrusions 18 are rotatably connected to the surface of the mounting plate 19, and one side of the rotating plate 19 corresponds to the position of the snap-fit block 20. By providing the rotating plate 19, when the baffle 12 is pressed down to insert the snap-fit strip 15 into the slot 14, the rotating plate 19 is rotated to fasten the snap-fit block 20, thereby fixing the baffle 12.
[0021] Electric lifting frames 2 are fixedly installed at the center of both sides of the processing table 1. A top seat 3 is fixedly installed between the tops of the two electric lifting frames 2. A shearing blade 4 is fixedly installed at the bottom of the top seat 3. Connecting plates 5 are fixedly installed on both sides of the top of the shearing blade 4. By using electric lifting frames 2, the electric lifting frames 2 are controlled to extend and retract according to the thickness of the steel on the top of the processing table 1, thereby driving the shearing blade 4 to move on the top of the processing table 1, thus completing the shearing process of the steel.
[0022] Connecting rods 6 are slidably connected through both ends of the connecting plate 5. The bottom of the two connecting rods 6 is fixedly connected to a lower pressure plate 8, which is lower than the cutting edge of the shearing blade 4. A compression spring 7 is provided on the surface of the connecting rod 6 between the connecting plate 5 and the lower pressure plate 8. A blade groove 9 is provided at the center of the top of the processing table 1, and the blade groove 9 corresponds to the position of the shearing blade 4. With the compression spring 7, after the lower pressure plate 8 contacts the surface of the steel, as the shearing blade 4 continues to descend, the compression spring 7 is compressed, applying pressure to the lower pressure plate 8 to press the steel, thereby preventing the steel from being pushed up and deformed when the shearing blade 4 is performing shearing.
[0023] A rectangular groove 25 is provided on the top side of the processing table 1 away from the baffle 12. A motor 21 is fixedly installed on the surface of the processing table 1 located outside the rectangular groove 25. By providing the motor 21, the motor 21 drives the roller 22 to rotate, thereby making the conveyor belt 23 run, thus realizing the conveyor belt 23 to transport steel.
[0024] Two rollers 22 are rotatably connected between the inner walls of the rectangular groove 25 via bearings, and one of the rollers 22 is fixedly connected to the output end of the motor 21. A conveyor belt 23 is sleeved between the surfaces of the two rollers 22. Limiting blocks 24 are fixedly installed on both sides of the top of the rectangular groove 25. With the limiting blocks 24, when the steel is transported on the conveyor belt 23, the limiting blocks 24 block the steel, so that the steel will not be pushed out of the processing table 1 by the conveyor belt 23.
[0025] The working principle of this utility model is as follows:
[0026] When steel of different lengths needs to be cut, the position of the baffle 12 is modified. The rotating clamping plate 19 is rotated off the surface of the clamping block 20, and the baffle 12 is pulled out, causing the clamping strip 15 to leave the clamping slot 14. Then, the baffle 12 is pulled to allow the sliding strip 13 to drive the sliding seat 10 to slide on the T-slot 16 until the baffle 12 moves above the appropriate clamping slot 14. The baffle 12 is then pushed down to allow the clamping strip 15 to insert into the clamping slot 14. Finally, the rotating clamping plate 19 is rotated to fasten onto the surface of the clamping block 20, thus fixing the baffle 12 in place. This completes the conversion of the cutting length. The steel is placed on the conveyor belt 23, and the motor 21 is started to make the roller 22 drive the conveyor belt 23 to run, so that the steel is transported to the processing table 1 until it is close to the baffle 12. The electric lifting frame 2 is controlled to make the top seat 3 descend, which drives the shearing blade 4 and the connecting plate 5 to approach the steel. The lower pressure plate 8 contacts the steel. As the top seat 3 continues to descend, the pressure spring 7 is compressed and applies pressure to the lower pressure plate 8 to press it against the two sides of the steel. When the shearing blade 4 finishes cutting the steel, the two sides of the steel will not bulge or deform.
