Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, specifically to a steel plate cutting device and its usage method for the production of iron coils and drums. Background Technology

[0002] Iron coils, also known as steel drums, are packaging containers widely used in industries such as chemical, food, pharmaceutical, and petroleum. Their production quality directly affects the safety and stability of stored materials. Steel plates, as the core raw material for manufacturing iron coils, have a decisive influence on the strength, sealing performance, corrosion resistance, and service life of the final product due to their performance, specifications, and processing technology. In the process of making iron coils from steel plates, the steel plates need to be cut into appropriate sizes, which requires the use of steel plate cutting equipment.

[0003] Existing steel plate cutting equipment typically requires clamping devices to fix the steel plate during industrial production to ensure its stability in subsequent processing stages, prevent displacement or vibration, and guarantee forming quality and processing accuracy. However, steel plates used to make iron coil drums are often industrial materials produced in large batches continuously. Their production process involves multiple steps of picking up and placing, and clamping. While each step is essential, it increases the complexity and operation time of the production process, especially during frequent clamping and releasing. Therefore, under this multi-step, highly repetitive production mode, it is difficult to significantly improve overall production efficiency.

[0004] In view of this, we propose a steel plate cutting device for the production of iron coil drums. Summary of the Invention

[0005] The purpose of this invention is to provide a steel plate cutting device and method for the production of iron coil drums, addressing the problem mentioned in the background art that the steel plates used in the production of iron coil drums are often industrial materials produced in large batches continuously. The production process involves multiple steps of picking up and placing, clamping, and so on. While each step is essential, it increases the complexity and time of the production process, especially during frequent clamping and releasing. Therefore, under this multi-step, highly repetitive production mode, it is difficult to significantly improve overall production efficiency. To achieve the above objective, this invention provides the following technical solution: a steel plate cutting device for the production of iron coil drums, comprising a cutting base, an L-shaped plate fixedly connected to the left side of the top of the cutting base, a cutting machine disposed at the bottom of the L-shaped plate, a C-shaped frame fixedly connected to the right side of the top surface of the cutting base, a fixing mechanism for clamping the steel plate movably inserted into the horizontal plate of the C-shaped frame, and movable grooves provided at the bottom of the left vertical plate and the right side of the right vertical plate of the C-shaped frame, with a moving mechanism for processing the steel plate slidably disposed inside the movable grooves.

[0006] Preferably, the fixing mechanism includes an L-shaped rod, the vertical part of which is movably inserted into the interior of the horizontal plate of the C-shaped frame. An L-shaped groove is formed in the middle of the side of the vertical part of the L-shaped rod. A limit rod is fixedly connected to the right side of the right vertical plate of the C-shaped frame. The side of the limit rod slides in cooperation with the interior of the L-shaped groove. When the telescopic rod of the telescopic cylinder drives the second rack to move, it can drive the L-shaped rod to deflect.

[0007] Preferably, a helical gear is fixedly sleeved on the lower side of the vertical side of the L-shaped rod; a rectangular strip is movably inserted into the bottom end of the vertical rod of the L-shaped rod; the bottom of the rectangular strip is rotatably connected to the top of the cutting seat; a rotating gear is fixedly sleeved on the side of the rectangular strip; a round rod is movably inserted into the rear side of the top of the horizontal bar of the L-shaped rod; a C-shaped extrusion strip is fixedly connected to the bottom end of the round rod; a limit strip is fixedly connected to the top of the round rod; the bottom of the limit strip contacts the top of the horizontal bar of the L-shaped rod; and the round... A compression spring is fixedly sleeved on the side of the rod. The top end of the compression spring is fixedly connected to the bottom of the horizontal bar of the L-shaped rod, and the bottom end of the compression spring is fixedly connected to the top of the vertical bar of the C-shaped extrusion strip. Two arc-shaped anti-slip strips are fixedly connected to the bottom of the horizontal bar of the C-shaped extrusion strip. The top of the vertical bar of the C-shaped extrusion strip is fixedly connected to the side of the limiting strip through a connecting strip. When the L-shaped rod rotates, it can drive the round rod on its side and the C-shaped extrusion strip to deflect, so that the deflected C-shaped extrusion strip clamps the upper side of the steel plate.

[0008] Preferably, the moving mechanism includes two T-shaped blocks. The right T-shaped block is slidably connected inside the right moving groove, and the left T-shaped block is slidably connected inside the left moving groove. A first rack is fixedly connected to the right side of the horizontal block of the left T-shaped block, and the first rack meshes with a rotating gear. A support plate is fixedly connected to the left side of the horizontal block of the left T-shaped block, and the support plate slides with the top of the cutting seat. The two T-shaped blocks enable the first rack and the second rack to move horizontally during movement.

[0009] Preferably, a telescopic cylinder is fixedly connected to the right side of the top surface of the cutting seat, and a second rack is fixedly connected to the rear side of the telescopic rod of the telescopic cylinder. The side of the second rack is fixedly connected to the side of the cross block of the T-shaped block on the right side. The second rack meshes with a helical gear. When the second rack moves, it can drive the second rack to move backward and drive the helical gear L-shaped rod to rotate and move.

[0010] Preferably, a stabilizing block is fixedly connected to the bottom of the support plate, and a straight groove that cooperates with the stabilizing block is opened on the top of the cutting seat. Two reinforcing legs are fixedly connected to the bottom of the cutting seat. The reinforcing legs can increase the stability of the steel plate cutting device during operation, while the straight groove can enable the support plate to move vertically and stably through the stabilizing block when it moves.

[0011] Preferably, the bottom of the horizontal plate of the L-shaped plate is provided with a guide rail, the side of the guide rail cooperates with the slider of the cutting machine, and a cooling pipe is fixedly connected to the side of the cutting machine. The cutting fluid is delivered through the cooling pipe to cool the steel plate when the cutting machine cuts it, and the guide rail enables the cutting machine to cut the steel plate stably along a straight line.

[0012] Preferably, the method for cutting steel plates for iron coil production includes the following steps:

[0013] S1. First, place the steel plate to be cut on top of the support plate. Then, the telescopic rod of the telescopic cylinder drives the second rack to move backward and contact the side of the helical gear, causing the helical gear to drive the L-shaped rod to rotate counterclockwise. At the same time, the limiting rod limits the L-shaped groove, causing the L-shaped rod to drive the rotating gear on its side to rotate. The rotating gear drives the first rack, T-shaped block and the support plate on its side to move backward, thus quickly moving the steel plate to be cut to the position where it needs to be cut.

[0014] S2. When the L-shaped rod rotates, it drives the round rod to deflect, and through the round rod, it drives the limiting strip and C-shaped extrusion strip on its side to rotate. When the L-shaped rod drives the L-shaped groove inside to rotate, the limiting rod moves through the horizontal groove of the L-shaped groove to the bottom of the vertical groove of the L-shaped groove. Then, through the rotation of the L-shaped rod and the limiting of the L-shaped groove, the L-shaped rod moves downward to the rectangular strip. At the same time, it drives the round rod, the limiting strip, and the C-shaped extrusion strip to move downward as a whole. At this time, the C-shaped extrusion strip can quickly clamp the steel plate to be cut above.

[0015] S3. After the steel plate is cut, the telescopic cylinder's telescopic rod drives the second rack forward, causing the second rack to drive the helical gear and L-shaped rod to rotate clockwise. This causes the L-shaped rod to drive the C-shaped extrusion strip upward while simultaneously deflecting backward. At the same time, the rotation of the L-shaped rod drives the rotating gear to rotate, causing the support plate and the cut steel plate on its upper side to move backward. This facilitates the workers to quickly remove the cut steel plate, reducing the possibility of injury to the workers caused by the cutting device.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] In this invention, the telescopic cylinder drives the second rack to move backward and contact the side of the helical gear, causing the helical gear to drive the L-shaped rod to rotate counterclockwise. At the same time, the limiting rod limits the L-shaped groove, causing the L-shaped rod to drive the rotating gear on its side to rotate. The rotating gear drives the first rack, T-shaped block and support plate to move backward, thus moving the steel plate to be cut above the support plate to the position where it needs to be cut. This reduces the complexity of the production process, reduces the operation time, and increases the efficiency of steel plate cutting.

[0018] In this invention, when the L-shaped rod drives the round rod to deflect, and the round rod drives the limiting strip and the C-shaped extrusion strip to rotate, when the L-shaped rod drives the L-shaped groove inside to rotate, the limiting rod moves through the horizontal groove of the L-shaped groove to the bottom of the vertical groove of the L-shaped groove. Then, through the rotation of the L-shaped rod and the limiting of the L-shaped groove, the L-shaped rod moves downward towards the rectangular strip, while simultaneously driving the round rod, the limiting strip, and the C-shaped extrusion strip to move downward as a whole. At this time, the C-shaped extrusion strip can quickly clamp the steel plate to be cut above it.

[0019] In this invention, after the steel plate is cut, the telescopic cylinder drives the second rack to move forward, causing the second rack to drive the helical gear and the L-shaped rod to rotate clockwise. This causes the L-shaped rod to drive the C-shaped extrusion strip to move upward and deflect backward. At the same time, the rotation of the L-shaped rod drives the rotating gear to rotate, causing the support plate and the cut steel plate to move backward. This makes it easier for workers to quickly remove the cut steel plate and reduces the possibility of injury to workers caused by the cutting device. Attached Figure Description

[0037] The method of use and advantages of the present invention: The working process of this steel plate cutting device for the production of iron coil drums is as follows:

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown,

[0039] S1. First, place the steel plate to be cut above the support plate 603. Then, the telescopic rod of the telescopic cylinder 101 drives the second rack 102 to move backward and contact the side of the helical gear 4011, causing the helical gear 4011 to drive the L-shaped rod 401 to rotate counterclockwise. At the same time, the limiting rod 403 limits the L-shaped groove 402, causing the L-shaped rod 401 to drive the rotating gear 404 on its side to rotate. The rotating gear 404 drives the first rack 602, the T-shaped block 601 and the support plate 603 on its side to move backward, which can quickly move the steel plate to be cut to the position where it needs to be cut, thereby reducing the complexity of the production process, reducing the operation time and increasing the efficiency of steel plate cutting.

[0040] S2. When the L-shaped rod 401 rotates, it drives the round rod 405 to deflect, and the round rod 405 drives the limiting strip 407 and the C-shaped extrusion strip 406 on its side to rotate. When the L-shaped rod 401 drives the L-shaped groove 402 inside to rotate, the limiting rod 403 moves through the horizontal groove of the L-shaped groove 402 to the bottom of the vertical groove of the L-shaped groove 402. Then, through the rotation of the L-shaped rod 401 and the limiting of the L-shaped groove 402, the L-shaped rod 401 moves downward to the rectangular strip 4012. At the same time, it drives the round rod 405, the limiting strip 407, and the C-shaped extrusion strip 406 to move downward as a whole. At this time, the C-shaped extrusion strip 406 can quickly clamp the steel plate to be cut above.

[0041] S3. After the steel plate is cut, the telescopic rod of the telescopic cylinder 101 drives the second rack 102 to move forward, causing the second rack 102 to drive the helical gear 4011 and the L-shaped rod 401 to rotate clockwise. This causes the L-shaped rod 401 to drive the C-shaped extrusion strip 406 to move upward and deflect backward. At the same time, the rotation of the L-shaped rod 401 drives the rotating gear 404 to rotate, causing the support plate 603 and the cut steel plate on its upper side to move backward. This facilitates the workers to quickly remove the cut steel plate and reduces the possibility of injury to the workers caused by the cutting device.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.

A method for cutting steel plates for the production of iron coil drums, using a steel plate cutting apparatus for the production of iron coil drums as described in any one of claims 1-7, characterized in that, Includes the following steps: S1. First, place the steel plate to be cut on the support plate (603). Then, the telescopic rod of the telescopic cylinder (101) drives the second rack (102) to move backward and contact the side of the helical gear (4011), so that the helical gear (4011) drives the L-shaped rod (401) to rotate counterclockwise. At the same time, the limiting rod (403) limits the L-shaped groove (402), so that the L-shaped rod (401) drives the rotating gear (404) on its side to rotate. The rotating gear (404) drives the first rack (602), the T-shaped block (601) and the support plate (603) on its side to move backward, so that the steel plate to be cut can be quickly moved to the position where it needs to be cut. S2. When the L-shaped rod (401) rotates, it drives the round rod (405) to deflect. The round rod (405) drives the limiting strip (407) and the C-shaped extrusion strip (406) on its side to rotate. When the L-shaped rod (401) drives the L-shaped groove (402) inside to rotate, the limiting rod (403) moves through the horizontal groove of the L-shaped groove (402) to the bottom of the vertical groove of the L-shaped groove (402). Through the rotation of the L-shaped rod (401) and the limiting of the L-shaped groove (402), the L-shaped rod (401) moves downward to the rectangular strip (4012). At the same time, it drives the round rod (405), the limiting strip (407), and the C-shaped extrusion strip (406) to move downward as a whole. At this time, the C-shaped extrusion strip (406) can quickly clamp the steel plate to be cut above. S3. After the steel plate is cut, the telescopic rod of the telescopic cylinder (101) drives the second rack (102) to move forward, so that the second rack (102) drives the helical gear (4011) and the L-shaped rod (401) to rotate clockwise. This causes the L-shaped rod (401) to drive the C-shaped extrusion strip (406) to move upward and deflect backward. At the same time, the rotation of the L-shaped rod (401) drives the rotating gear (404) to rotate, which drives the support plate (603) and the steel plate cut on its upper side to move backward. This makes it easier for the workers to quickly remove the cut steel plate and reduces the possibility of injury to the workers caused by the cutting device.
