Description

Technical Field

[0001] This utility model relates to the field of punching and shearing machine technology, specifically a novel multifunctional punching and shearing mechanism. Background Technology

[0002] A multi-functional punching and shearing machine is a type of equipment that can perform punching and shearing processes on metal sheets and profiles. Its punching part mainly consists of a punch, a die, and a power mechanism. After the equipment is started, the power mechanism generates strong pressure, which causes the punch to move downwards rapidly. When the punch is under pressure, it impacts the sheet or profile at extremely high speed, ultimately forming a round, square, or other specific shaped hole. At the same time, its shearing component generally consists of an upper blade, a lower blade, and a transmission mechanism. The transmission mechanism drives the upper blade to reciprocate, and the material breaks and separates under the influence of shearing force, thus enabling the shearing of sheet or profile. By cleverly designing and combining different dies and cutters, the multi-functional punching and shearing machine can achieve multiple processing functions on one machine, which improves processing efficiency and increases equipment utilization.

[0003] A search revealed a Chinese patent document disclosing a punching and shearing mechanism for a steel mesh punching and shearing machine (publication number: CN220659082U). This mechanism includes a punching and shearing machine body, a worktable at the upper end of the body, rollers on the inner wall of the worktable, limit mechanisms on both sides of the worktable, a pressing mechanism at the upper end of the worktable, and a mounting frame on one side of the worktable. Through the combined action of a servo motor, rotating rod, sliding plate, fixed rod, fixed groove plate, and limit rod, the punching and shearing mechanism can limit the movement of the steel mesh. Through the combined action of a connecting frame, threaded rod, handwheel, moving plate, and pressure roller, the punching and shearing mechanism can press the steel mesh. Through the combined action of a fixed seat, mounting groove, guide rod, spring, insert block, extrusion cone, fixing bolt, and cutter, the punching and shearing mechanism can disassemble the cutter. However, it still has many shortcomings:

[0004] The punching and shearing mechanism has a relatively simple function and a small scope of application. It mainly focuses on specific stages of steel mesh processing. Through limiting mechanisms, pressing mechanisms and detachable cutters, it realizes the limiting, pressing and cutting of steel mesh. However, it can only process steel mesh and cannot meet the punching and shearing needs of various profiles such as square steel, angle steel, H-beams, round steel and flat steel.

[0005] This punching and shearing mechanism uses a traditional drive method, which results in significant energy loss during power transmission and makes it impossible to achieve precise power output. In the stamping stage, it lacks the ability to adjust the pressure according to the material thickness and hardness, which easily leads to energy waste. In the shearing process, it is also difficult to achieve efficient motion conversion, resulting in low overall processing efficiency.

[0006] This type of punching and shearing mechanism has a single function. If a company needs to complete multiple processing tasks, it needs to purchase additional equipment such as punching machines and shearing machines, which not only increases equipment purchase costs but also occupies more production space, increasing site rental and management costs. In contrast, this utility model significantly reduces the overall cost through multi-functional integration. Utility Model Content

[0007] The purpose of this utility model is to provide a new type of multi-functional punching and shearing mechanism to solve the problem that the punching and shearing mechanisms proposed in the background art have relatively simple functions and limited application scope. They mainly focus on specific links in the processing of expanded metal mesh, and realize the limiting, pressing and cutting of expanded metal mesh through limiting mechanisms, pressing mechanisms and detachable cutters. However, they can only process expanded metal mesh and cannot meet the punching and shearing needs of various profiles such as square steel, angle steel, H-beams, round steel and flat steel.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a novel multifunctional punching and shearing mechanism, including a punching and shearing mechanism base, a punching and shearing mechanism body fixedly disposed at the top of the punching and shearing mechanism base, eye bolts fixedly disposed on both sides of the top of the punching and shearing mechanism body, two plate placement openings opened in the middle of the surface of the punching and shearing mechanism body, an active structure disposed on one side of the punching and shearing mechanism body, a shearing structure disposed at one end of the active structure, and a stamping structure disposed on one side of the shearing structure.

[0009] Preferably, the active structure includes a motor base, the bottom end of which is fixedly mounted on one side of the bottom end of the punching and shearing mechanism body. A servo motor is mounted on one side of the motor base. A small pulley is fixedly connected to the output end of the servo motor. A transmission belt is driven to one side of the small pulley. A large pulley is driven to the end of the transmission belt away from the small pulley. A central rotating rod is fixedly mounted in the middle of the large pulley. One end of the central rotating rod extends through the surface of the punching and shearing mechanism body into the interior of the punching and shearing mechanism body. A transmission wheel is fixedly connected to one end of the large pulley. The servo motor can precisely adjust its output parameters according to different processing requirements, ensuring that the transmission wheel operates stably at the set speed and direction. The subsequent shearing and stamping operations provide precise power rhythm. The belt drive structure can achieve stable power transmission with high efficiency. The combination of small and large pulleys forms the transmission ratio, which can be amplified or reduced according to actual needs to meet the power requirements under different working conditions. At the same time, during the belt drive process, the friction between the transmission belt and the pulley can effectively buffer the impact and vibration during power transmission, avoiding damage to equipment parts due to excessive instantaneous impact force, thereby extending the overall service life of the equipment. The overall layout is reasonable and occupies little space. Within the limited space of the main body of the punching and shearing mechanism, the power transmission system can be efficiently integrated, making the entire punching and shearing mechanism compact and easy to install and maintain.

[0010] Preferably, the stamping structure includes a hydraulic cylinder, one end of which is fixedly connected to one side of a transmission wheel. A reciprocating slider is located at the end of the hydraulic cylinder furthest from the transmission wheel. The surface of the reciprocating slider is provided with several evenly distributed guide wheels. A connecting plate is fixedly connected to the bottom end of the reciprocating slider, and a shearing cutter is fixedly mounted at the bottom end of the connecting plate. Both ends of the shearing cutter have sheet metal shearing openings. The hydraulic cylinder can provide stable and large driving force, enabling the shearing cutter to perform shearing operations on various metal sheets with sufficient force when driving the reciprocating slider, whether it is thin flat steel or thick square steel or H-shaped steel. Hydraulic cylinders ensure that the shearing blade smoothly cuts into the sheet metal, completing the shearing task and greatly improving the processing capacity and applicability of the equipment. Guide wheels effectively reduce the frictional resistance of the slider during movement and limit its direction of movement, ensuring that it can only reciprocate linearly along a predetermined trajectory. This not only guarantees the positional accuracy of the shearing blade during the shearing process and avoids shearing deviations caused by slider wobbling, but also improves the flatness and smoothness of the shearing, thus enhancing the processing quality. The shearing cutters at both ends of the shearing blade can process two parts of the sheet metal simultaneously, which greatly improves shearing efficiency and production efficiency compared to single-cut blades.

[0011] Preferably, the positions of the two shearing openings of the sheet metal correspond to the positions of the two placement openings of the sheet metal, and the shearing blade is made of high-speed steel. With the shearing openings corresponding to the placement openings, operators do not need to perform complex positioning adjustments when placing the sheet metal; they only need to accurately place the sheet metal into the placement opening to ensure that the sheet metal is in the optimal shearing position. This simplifies the operation process and improves operational convenience. High-speed steel has high hardness, good wear resistance, and a certain degree of toughness, which can effectively resist the wear of the blade on the sheet metal during the shearing of various metal sheets, maintain the sharpness and shape stability of the blade, and extend the service life of the blade.

[0012] Preferably, the stamping structure includes a hydraulic station, with two oil pipes fixedly installed at the output end of the hydraulic station. A cylinder is installed at the end of each oil pipe furthest from the hydraulic station. A cylinder mounting base is fixedly connected to the top of each cylinder. Both ends of the cylinder mounting base are fixedly connected to the two sides inside the main body of the stamping and shearing mechanism. A stamping head is fixedly installed at the bottom of the cylinder, and a punching seat is installed at the bottom of the stamping head. The punching seat is fixedly installed inside the main body of the stamping and shearing mechanism. The combination of the hydraulic station and the cylinder generates a powerful thrust, driving the stamping head downwards to perform stamping operations on the sheet metal. When stamping round holes in the steel plate… The powerful thrust ensures that the stamping head can quickly and accurately penetrate the steel plate to form a round hole that meets the requirements. Even with thicker steel plates or high-strength steel, this stamping structure can ensure smooth stamping and meet the stamping needs of plates of different thicknesses and materials. Furthermore, the hydraulic station can flexibly adjust the output pressure according to different stamping requirements. For plates of different thicknesses and materials, as well as stamping dies of different specifications, operators can adjust the pressure parameters of the hydraulic station to allow the stamping head to perform stamping operations at appropriate pressures. This enables the equipment to adapt to diverse stamping tasks, improving its versatility and processing adaptability.

[0013] Preferably, the position of the middle part of the bottom end of the punch head corresponds to the position of the middle part of the surface of the punching seat, and the punch head is made of carbon tool steel. The precise correspondence between the bottom end of the punch head and the middle part of the surface of the punching seat ensures that the punch head can accurately act on the predetermined position on the punching seat during the punching process, avoiding the generation of defective products due to positional deviation, improving the product qualification rate and processing quality. Carbon tool steel has a certain hardness and wear resistance, which can meet the requirements of general stamping work. At the same time, the processing technology of carbon tool steel is relatively simple, which facilitates the manufacturing and maintenance of the punch head, further reducing production and maintenance costs.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This multi-functional punching and shearing mechanism uses a hydraulic cylinder for punching and a motor reducer and crank-slider mechanism for shearing. Compared with the traditional fully hydraulic drive, it has significant energy-saving advantages. During the shearing process, the rotational motion of the motor can be efficiently converted into linear reciprocating motion with low energy loss. During the punching process, the hydraulic cylinder can accurately provide the required pressure according to actual needs, avoiding energy waste. At the same time, this power system can achieve high processing efficiency. The periodic reciprocating motion design makes the punching and shearing work proceed in an orderly manner, reducing the idle time of the equipment and increasing the processing output per unit time.

[0016] This multi-functional punching and shearing mechanism differs from most punching and shearing machines on the market, possessing wide adaptability and flexibility. Its shearing module and punching module are completely independent and can operate independently. Users can flexibly choose to use the shearing module or the punching module according to actual working conditions and processing needs, reducing unnecessary energy consumption and equipment wear, or use the two modules simultaneously to work together to improve production efficiency. This flexible working mode enables the equipment to adapt to different production tasks and processing scenarios. Whether it is the diversified order production of small processing enterprises or the assembly line operation of large factories, it can handle it with ease, greatly enhancing the versatility and adaptability of the equipment and expanding its application scope.

[0017] This multi-functional punching and shearing mechanism integrates shearing and punching functions, and can process various profiles such as square steel, angle steel, H-beams, round steel and flat steel, which can meet a variety of processing tasks and needs. It not only reduces equipment purchase costs, but also saves production space. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-4This utility model provides a novel multifunctional punching and shearing mechanism, including a punching and shearing mechanism base 1, a punching and shearing mechanism body 2 fixedly installed at the top of the punching and shearing mechanism base 1, and lifting eye screws 3 fixedly installed on both sides of the top of the punching and shearing mechanism body 2. Two plate placement openings 4 are opened in the middle of the surface of the punching and shearing mechanism body 2. An active structure is provided on one side of the punching and shearing mechanism body 2, a shearing structure is provided at one end of the active structure, and a stamping structure is provided on one side of the shearing structure.

[0025] Furthermore, the active structure includes a motor base 5, the bottom of which is fixedly mounted on one side of the bottom of the punching and shearing mechanism body 2. A servo motor 6 is provided on one side of the motor base 5. A small pulley 7 is fixedly connected to the output end of the servo motor 6. A transmission belt 8 is connected to one side of the small pulley 7. A large pulley 9 is connected to the end of the transmission belt 8 away from the small pulley 7. A central rotating rod 10 is fixedly mounted in the middle of the large pulley 9. One end of the central rotating rod 10 passes through the surface of the punching and shearing mechanism body 2 and extends into the interior of the punching and shearing mechanism body 2. A transmission wheel 11 is fixedly connected to one end of the large pulley 9.

[0026] When in use, the servo motor 6 is started to run the equipment, which drives the small pulley 7 connected to its output end to rotate. The small pulley 7 transmits power to the large pulley 9 through the transmission belt 8. The central rotating rod 10 in the middle of the large pulley 9 also rotates, driving the transmission wheel 11 fixed at one end of the large pulley 9 to rotate, providing a stable power input for the subsequent shearing and stamping structures.

[0027] Furthermore, the stamping structure includes a hydraulic cylinder 12, one end of which is fixedly connected to one side of the transmission wheel 11. The end of the hydraulic cylinder 12 away from the transmission wheel 11 is provided with a reciprocating slider 13. The surface of the reciprocating slider 13 is provided with a number of evenly distributed guide wheels 14. The bottom end of the reciprocating slider 13 is fixedly connected to a connecting plate 15. The bottom end of the connecting plate 15 is fixedly provided with a shearing cutter 16. Both ends of the shearing cutter 16 are provided with sheet metal shearing openings 17.

[0028] When in use, the transmission wheel 11 rotates, driving the hydraulic cylinder 12 fixedly connected to one side of it to move. The hydraulic cylinder 12 pushes the reciprocating slider 13 away from the transmission wheel 11. Under the action of the guide wheels 14 evenly distributed on the surface of the reciprocating slider 13, the reciprocating slider 13 moves in a straight line along a fixed trajectory. The connecting plate 15 at the bottom of the reciprocating slider 13 drives the shearing blade 16 fixed at its bottom to move synchronously. When the shearing blade 16 moves to the plate placement opening 4, the plate shearing openings 17 at both ends are used to shear the plate placed in the plate placement opening 4.

[0029] Furthermore, the positions of the two plate shearing openings 17 correspond to the positions of the two plate placement openings 4, and the shearing blade 16 is made of high-speed steel.

[0030] During use, the operator places the sheet material to be processed into the two sheet material placement ports 4. When the shearing blade 16 moves over under the drive of the reciprocating slider 13, the high-speed steel shearing blade 16, with its high hardness and wear resistance, quickly and stably shears the sheet material, ensuring that the shearing process is efficient and precise, while reducing blade wear and extending the tool life.

[0031] Furthermore, the stamping structure includes a hydraulic station 18, with two oil pipes 19 fixedly installed at the output end of the hydraulic station 18. A cylinder 20 is provided at the end of the two oil pipes 19 away from the hydraulic station 18. A cylinder mounting seat 21 is fixedly connected to the top of the cylinder 20. The two ends of the cylinder mounting seat 21 are fixedly connected to the two sides inside the main body 2 of the punching and shearing mechanism, respectively. A punching head 22 is fixedly installed at the bottom of the cylinder 20. A punching seat 23 is provided at the bottom of the punching head 22. The punching seat 23 is fixedly installed inside the main body 2 of the punching and shearing mechanism.

[0032] When in use, the hydraulic station 18 is started, and hydraulic oil is supplied to the cylinder 20 through two oil pipes 19. Under pressure, the piston rod of the cylinder 20 extends downward, driving the punch head 22 to move downward. The punch head 22 moves toward the punching seat 23 below. When the punch head 22 contacts the plate placed on the punching seat 23, it performs punching and punching operations on the plate.

[0033] Furthermore, the position of the middle part of the bottom end of the punch head 22 corresponds to the position of the middle part of the surface of the punch seat 23, and the punch head 22 is made of carbon tool steel.

[0034] When in use, the sheet material to be punched and drilled is placed on the punching base 23 in advance to ensure that the punching head 22 accurately punches the predetermined position of the sheet material. The punching head 22, made of carbon tool steel, applies sufficient impact force to the sheet material under the pressure provided by the hydraulic station 18 to complete the punching work.

[0035] In this embodiment, the punching and shearing mechanism is first placed stably on the work site. It is then hoisted and positioned using eye bolts 3 to ensure stability. Based on the type, size, and processing requirements of the sheet metal to be processed, a suitable stamping die is selected and installed on the punching base 23. Simultaneously, the shearing blade 16 is confirmed to be in good condition. Sheets such as square steel, angle steel, H-beams, round steel, or flat steel are placed into the equipment through their corresponding plate placement openings 4. The servo motor 6 is started, and the active structure begins to operate, driving the transmission wheel 11 to rotate. If shearing is required, the transmission wheel 11 drives the hydraulic cylinder 12 to move the reciprocating slider 13, and the shearing blade 16 shears the sheet metal. If stamping is required, the hydraulic station 18 is started, and hydraulic oil drives the cylinder 20 through the oil pipe 19, causing the punching head 22 to move downwards to punch and punch holes in the sheet metal. Depending on the specific working conditions, the shearing and stamping functions can be used individually, or both functions can be activated simultaneously to achieve multi-functional processing of the sheet metal.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
