Description

Technical Field

[0001] The present invention relates to a steel plate processing equipment, and more specifically, to a steel plate cutting and forming mechanism and a control method thereof. Background Art

[0002] Steel plate is a flat steel material that is poured with molten steel and pressed after cooling. Steel plate cutting refers to the process of cutting and processing steel structures according to needs in industrial production. Common cutting techniques include blade cutting, flame cutting, water cutting and plasma cutting. At present, blade cutting and flame cutting are the most widely used. The processed steel plates are divided into thin steel plates, medium and thick steel plates, and extra thick steel plates according to thickness. Steel plates are divided into hot rolling and cold rolling according to rolling. Thin plates are divided into ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron thin plates according to steel types. They are divided into oil drum plates, enamel plates, bulletproof plates, etc. according to professional uses. They are divided into galvanized thin plates, tinned thin plates, lead-plated thin plates, plastic composite steel plates, etc. according to surface coatings. The steel types of thick steel plates are generally the same as those of thin steel plates.

[0003] At present, when the existing steel plate cutting device is working, the fixing of the steel plate is rather cumbersome and complicated, and the disassembly and assembly process is time-consuming. At the same time, when the steel plate is cut at different widths, the steel plate needs to be frequently and repeatedly fixed, and it is difficult to move and adjust the steel plate left and right and front and back, resulting in low work efficiency. At the same time, the movement, positioning and cutting of the steel plate are usually adjusted manually, and the adjustment accuracy is poor, which easily leads to overlapping cutting positions and large cutting residues, resulting in waste of resources. In addition, manual adjustment is time-consuming and labor-intensive, and has certain safety hazards. At the same time, the waste volume and size after cutting are different, which makes sorting difficult, and waste treatment and recycling are inconvenient.

[0004] At the same time, when a blade is used to cut a steel plate, due to positioning problems and problems with the cutter, the overall flatness of the cut surface after cutting is poor and the cutting quality is low. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a steel plate cutting and forming mechanism and a control method thereof which are simple to operate, highly automated, convenient to cut, have high resource utilization, and are convenient for waste disposal after cutting.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a steel plate cutting and forming mechanism, comprising a base, on which a material organization mechanism, a cutting mechanism and a discharging mechanism are arranged, one side of the material organization mechanism is also provided with a material transport rack, and a feeding plate is also provided on the side of the material organization mechanism close to the material transport rack, the feeding plate is used to guide the steel plate at the material transport rack, and a material guide clamp is also provided on the other side of the material organization mechanism, the cutting mechanism comprises a cutting frame and a cutting base arranged on the base, the cutting frame is provided with a lifting cylinder and a cutting assembly arranged at the bottom of the lifting cylinder, the lifting cylinder is configured to move back and forth along the vertical direction of the cutting frame, the position of the cutting assembly matches the position of the cutting base, and the discharging mechanism is used to cut and collect the waste materials after processing.

[0007] The present invention is further configured as follows: a feeding roller is provided in the material-forming mechanism, and the feeding roller is used to clamp and guide the steel plate to move along the length direction of the base.

[0008] Preferably, a plurality of limit rods are further provided in the material-forming mechanism, a rotating shaft is provided in the limit rods, the limit rods are arranged along the width direction of the base, and the distance between adjacent limit rods matches the width of the steel plate.

[0009] The present invention is further configured as follows: the cutting assembly includes a clamping member and a cutter arranged in the clamping member, and a compression spring is further provided between the clamping member and the lifting cylinder. When the compression spring is compressed, the cutter is exposed outside the clamping member.

[0010] Preferably, a stripping rod is provided at one end of the cutting frame, and the stripping rod is arranged on the lifting cylinder. A positioning head is also provided at the other end of the cutting frame, and a positioning rod is provided on the cutting base, and the position of the positioning rod matches the position of the positioning head.

[0011] Preferably, the cutting mechanism is further provided with a material chute, which is arranged along the width direction of the base and at least spans the stripping rod.

[0012] The present invention is further configured as follows: the discharging mechanism includes a cutting knife arranged on a base and a waste collection rack arranged on one side of the cutting knife, the cutting knife includes a waste trough and a knife holder arranged on the waste trough, a return spring is also provided between the knife holder and the waste trough, a pressure plate is extended on the lifting cylinder, and the pressure plate is used to press the knife holder and cut the waste when the lifting cylinder moves downward.

[0013] Preferably, the waste collection rack comprises a placement panel and a guide cylinder arranged at the bottom of the placement panel, and the guide cylinder is used to drive the placement panel to tilt.

[0014] The present application also provides a control method for a steel plate cutting and forming mechanism, which also includes a displacement detection device and a counting device, wherein the displacement detection device is used to detect the specific distance that the feeding roller drives the steel plate to move, and the counting device is used to record the number of reciprocating movements of the lifting cylinder. The control method includes the following steps: S1, installing and inserting the steel plate into the cutting and forming mechanism, and fixing it through the material arrangement mechanism and the material discharging mechanism;

[0015] S2, start the device, the feeding roller drives the steel plate to move on the base, and the moving distance is set to D;

[0016] S3, the displacement detection device detects the moving distance D1 of the current steel plate, and detects D1 at the same time. If D1 < D, it is judged that the moving distance of the current steel plate is too short, and the feeding roller continues to drive the steel plate. Otherwise, it is judged that the movement of the current steel plate is completed, and jumps to S4 to continue detection;

[0017] S4, after the steel plate is moved, the lifting cylinder moves downward, driving the cutting assembly to fit with the cutting base, completing the cutting of the steel plate, and the moving distance of the lifting cylinder is L1, and at the same time, the value N of the counting device is technically changed to N+1;

[0018] S5, the whole mechanism detects the value N of the counting device. If N≠4, it is judged that the waste on the current discharging mechanism does not meet the discharging requirements, and the device jumps back to S3 for another detection. On the contrary, if N=4, it is judged that the waste on the current discharging mechanism meets the discharging requirements, and the lifting cylinder moves downward to drive the cutting assembly to fit with the cutting base to complete the cutting of the steel plate. The moving distance of the lifting cylinder is 1.5L1. While cutting the steel plate, the pressure plate on the lifting cylinder presses the cutting knife to cut off the waste steel plate on the discharging mechanism. The waste steel plate falls off and falls on the placement panel. At the same time, the count of the value N in the counting device is reset to N=0, and it jumps back to S4 to continue detection;

[0019] S6. The guide cylinder at the bottom of the placement panel contracts and drives the placement panel to tilt, and the waste steel plates on the placement panel are separated from the placement panel and manually sorted, stacked and stored.

[0020] Preferably, the step S3 further includes a material transport detection of the steel plate, including the following steps: S31, setting the driving time to T1 during the process of the feeding roller driving the steel plate;

[0021] S32. After the T1 time period, the displacement detection device detects the moving distance D2 of the current steel plate. If D2≤2D, it is determined that the current steel plate cannot move and the staff is notified to detect. Otherwise, it is determined that the current steel plate moves normally and the mechanism continues to operate.

[0022] By adopting the above technical scheme, the beneficial effects are as follows: 1. The steel plate moves on the base and is cut into corresponding shapes on the steel plate through the cutting mechanism. The cut steel plate is separated from the base and stacked through the material chute next to the cutting mechanism, completing the cutting of the steel plate and the collection of the finished products. The processed waste steel plate can be cut and sorted and stored by the cutting knife on the discharging mechanism, and the waste steel plate can be cut and cut off after moving the same distance, so that the length of the waste material coming out of the discharging mechanism is fixed, which is convenient for the subsequent storage and processing of the waste material.

[0023] 2. Furthermore, a clamping piece is provided in the cutting assembly, and a compression spring is provided between the clamping piece and the lifting cylinder. After the lifting cylinder is pressed down, the clamping piece can cooperate with the cutting base to complete the clamping of the steel plate. At the same time, since the clamping piece and the cutting base are in conflict with each other, the compression spring contracts, and the cutter is exposed to the outside of the clamping piece, thereby completing the fixing and cutting of the steel plate in the cutting assembly. The cutting efficiency is high, and the cutting is performed in a closed chamber formed by the clamping of the clamping piece and the steel plate, which can prevent the splashing of debris during the cutting process, thereby increasing safety and improving the effect of the finished product after cutting. A stripping rod is provided at one end of the cutting frame, and the stripping rod can move synchronously with the lifting cylinder, and the position of the stripping rod is set at the position of the subsequent cutting position of the current cutting position. Generally speaking, after the cutting of the steel plate is completed and separated from the cutting base, the finished product and the steel plate are cut off, and the finished product is separated from the steel plate and collected through the material chute. At the same time, due to the friction between the finished product and the steel plate, the finished product is still in the steel plate after the cutting position is separated from the cutting base. In order to prevent the finished product from being cut by the subsequent discharging mechanism, the finished product in the steel plate is squeezed by the stripping rod, so that the finished product falls off and is collected through the material chute.

[0024] 3. At the same time, in order to move and drive the steel plate during the cutting process and increase the utilization rate of steel plate resources, a feeding roller for driving the steel plate is provided in the material-forming mechanism. The feeding roller is used to clamp the steel plate and drive the steel plate to move away from the transmission roller through the friction between the steel plate and the steel plate. At the same time, a limiting rod is provided in the material-forming mechanism. The limiting rod is arranged along the width direction of the base. At the same time, the distance between the limiting rods arranged on the same horizontal line matches the distance of the steel plates to be cut. Specifically, in the process of cutting the steel plates, in order to maximize the utilization of the steel plates and prevent the waste of resources caused by excessive residual area of ​​waste after cutting, a limiting rod is provided on the steel plates. During the cutting process, the distance between adjacent cutting points and the distance between the cutting point and the two ends of the steel plate usually only leaves a small residual amount, which ensures the integrity of the finished product after cutting is completed, while achieving the maximum utilization rate of the raw steel plate. In addition, since the distance between the cutting point and the two ends of the steel plate is only set with a small cutting margin, it is necessary to always keep the cutter within the range of the steel plate raw material during the cutting process and complete the cutting of the steel plate. The position of the steel plate on the base is limited by the limit rod, so that while the steel plate moves along the length direction of the base, the lateral jumping of the steel plate along the width direction of the base is prevented, thereby preventing the steel plate from offsetting in the cutting mechanism and affecting the effect of cutting the finished product.

[0025] 4. In order to facilitate the processing and collection of waste materials, the discharging mechanism includes a cutting knife arranged on a base and a waste collecting rack arranged on one side of the cutting knife. The cutting knife includes a waste trough and a knife holder arranged on the waste trough. A return spring is also arranged between the knife holder and the waste trough. A pressing plate is extended on the lifting cylinder, so that after the pressing plate presses the knife holder, the knife holder can cut off the steel plate waste in the waste trough, and is reset by the return spring after the lifting cylinder moves up. At the same time, a counting device is provided, and the counting device can count while the lifting cylinder moves. When the count reaches a set value, the lifting cylinder is controlled to output a larger displacement and clear the count. Specifically, in the process of moving the lifting cylinder, a first movement amount and a second movement amount are provided. The first movement amount is set as the lifting cylinder moving downward at a distance of L1, allowing the cutting component to cut the steel plate while the pressure plate on the lifting cylinder does not contact the tool holder of the discharging mechanism, that is, when the lifting cylinder moves downward at the first movement amount, the steel plate can be cut and formed without affecting the cut-off of the waste material, and the second movement amount is set as the lifting cylinder moving downward at a distance of 1.5L1, while the cutting component cuts the steel plate, the pressure plate on the lifting cylinder squeezes the tool holder of the discharging mechanism, that is, when the lifting cylinder moves downward at the second movement amount, the steel plate can be cut and formed while the discharging mechanism cuts off the steel plate waste, and at the same time, after the steel plate waste is cut off, the cut waste falls onto the placement panel, and the placement panel is tilted by the guiding cylinder to facilitate the waste material to slide out and complete storage.

The discharging mechanism 4 is used to cut and collect the waste materials after processing.

[0036] A feeding roller 24 is provided in the material-forming mechanism 2 , and the feeding roller 24 is used to clamp and guide the steel plate to move along the length direction of the base 1 .

[0037] Preferably, a plurality of limit rods 5 are further provided in the material-forming mechanism 2. A rotating shaft 51 is provided in the limit rods 5. The limit rods 5 are arranged along the width direction of the base 1, and the distance between adjacent limit rods 5 matches the width of the steel plate.

A positioning head 7 is also provided at the other end of the cutting frame 31, and a positioning rod 8 is provided on the cutting base 32, and the position of the positioning rod 8 matches the position of the positioning head 7.

[0040] Preferably, the cutting mechanism 3 is further provided with a material chute 9 , which is arranged along the width direction of the base 1 and at least spans the stripping rod 6 .

[0042] Preferably, the waste collection rack 42 includes a placement panel 10 and a guide cylinder 11 disposed at the bottom of the placement panel 10 , and the guide cylinder 11 is used to drive the placement panel 10 to tilt.

[0043] The steel plate moves on the base 1 and is cut into a corresponding shape by the cutting mechanism 3. The cut steel plate is separated from the base 1 and stacked through the material chute 9 next to the cutting mechanism 3, completing the cutting of the steel plate and the collection of the finished product. The processed waste steel plate can be cut and sorted and stored by the cutting knife 41 on the discharging mechanism 4, and the waste steel plate can be cut and cut off after moving the same distance, so that the length of the waste material coming out of the discharging mechanism 4 is fixed, which is convenient for the subsequent storage and processing of the waste material.

[0044] Furthermore, by providing a clamping piece 341 in the cutting assembly 34, a compression spring 343 is provided between the clamping piece 341 and the lifting cylinder 33, and the clamping piece 341 can cooperate with the cutting base 32 to complete the compression of the steel plate after the lifting cylinder 33 is pressed down. At the same time, since the clamping piece 341 and the cutting base 32 conflict with each other, the compression spring 343 shrinks, and the cutter 342 is exposed to the outside of the clamping piece 341, so as to complete the fixing and cutting of the steel plate in the cutting assembly 34, and the cutting efficiency is high. At the same time, the cutting is carried out in a closed chamber formed by the clamping of the clamping piece 341 and the steel plate, which can prevent the splashing of debris during the cutting process, increase the safety, and improve the cutting efficiency. The stripping rod 6 is arranged at one end of the cutting frame, and the stripping rod 6 can move synchronously with the lifting cylinder 33, and the position of the stripping rod 6 is arranged at the position of the subsequent cutting position of the current cutting position. Generally speaking, after the steel plate is cut and separated from the cutting base 32, the finished product and the steel plate are cut off, and the finished product is separated from the steel plate and collected through the material chute 9. At the same time, due to the friction between the finished product and the steel plate, the finished product is still in the steel plate after the cutting position is separated from the cutting base 32. In order to prevent the finished product from being cut by the subsequent discharging mechanism 4, the finished product in the steel plate is squeezed by the stripping rod 6, so that the finished product falls off and is collected through the material chute 9.

[0045] At the same time, in order to move and drive the steel plate during the cutting process and increase the utilization rate of steel plate resources, the material-forming mechanism 2 is provided with a feeding roller 24 for driving the steel plate. The feeding roller 24 is used to clamp the steel plate and drive the steel plate to move away from the transmission roller through the friction between the steel plate and the steel plate. At the same time, the material-forming mechanism 2 is also provided with a limiting rod 5. The limiting rod 5 is arranged along the width direction of the base 1. At the same time, the distance between the limiting rods 5 arranged on the same horizontal line matches the distance of the steel plates to be cut. Specifically, in the process of cutting the steel plates, in order to maximize the utilization of the steel plates and prevent the waste of resources caused by excessive residual area of ​​waste after cutting, the steel plates are During the cutting process, the distance between adjacent cutting points and the distance between the cutting point and the two ends of the steel plate usually only leaves a small residual amount, which ensures the integrity of the finished product after cutting is completed, while achieving the maximum utilization rate of the raw steel plate. In addition, since only a small cutting margin is set between the cutting point and the two ends of the steel plate, it is necessary to always keep the cutter 342 within the range of the steel plate raw material during the cutting process and complete the cutting of the steel plate. The position of the steel plate on the base 1 is limited by the limit rod 5, so that while the steel plate moves along the length direction of the base 1, the lateral jumping of the steel plate along the width direction of the base 1 is prevented, thereby preventing the steel plate from being offset in the cutting mechanism 3 and affecting the effect of cutting the finished product.

The moving distance of the lifting cylinder is 1.5L1. While cutting the steel plate, the pressure plate on the lifting cylinder presses the cutting knife to cut off the waste steel plate on the discharging mechanism. The waste steel plate falls off and falls on the placement panel. At the same time, the count of the value N in the counting device is reset to N=0, and it jumps back to S4 to continue detection;

[0051] S6. The guide cylinder at the bottom of the placement panel contracts and drives the placement panel to tilt, and the waste steel plates on the placement panel are separated from the placement panel and manually sorted, stacked and stored.
