Description

Technical Field

[0001] This invention belongs to the field of shearing machine technology, and in particular relates to a sheet metal shearing machine for use in the production of drum cooling machines. Background Technology

[0002] Shearing machines are commonly used sheet metal cutting equipment in the sheet metal processing industry. They mainly use the linear reciprocating motion of blades to perform cold shearing of metal sheets, completing fixed-length blanking and edge trimming operations. They are widely used in the production and processing of engineering machinery, cooling equipment, sheet metal chassis, steel structures, and other industries. Their working principle involves a power unit driving the upper blade holder and cutting blade downwards, which, in conjunction with the lower blade edge on the worktable, uses the shearing force of the blades to cut the sheet metal.

[0003] Before shearing, the thickness data of the sheet material needs to be collected manually or by relying on detection devices, and then the adjustment mechanism is driven to adjust the cutting gap, which is a cumbersome process. If the gap setting does not match the actual thickness of the sheet material, the sheet material is prone to shifting during shearing, resulting in burrs on the cut surface and misalignment, directly reducing the processing accuracy of the sheet material. Furthermore, the timing of the clamping mechanism and gap adjustment in some equipment is difficult to synchronize, leading to poor adaptability for sheet materials with varying thicknesses in drum coolers, making it difficult to simultaneously meet the dual requirements of sheet material clamping and positioning and adaptive gap adjustment. Therefore, we provide a sheet material shearing machine for drum cooler production to solve the above problems. Summary of the Invention

[0015] The present invention has the following beneficial effects: 1. The present invention achieves adaptive adjustment of the cutting gap by relying on the plate clamping action, and integrates plate clamping and gap adjustment into a mechanism. There is no need to configure additional thickness detection elements and independent adjustment drive components. The plate thickness is directly converted into a displacement signal inside the hydraulic system. While clamping the plate, the cutting gap between the cutting blade and the operating table is automatically adjusted. This can not only reliably clamp the plate during the shearing operation and suppress the plate movement, but also adapt to the plates produced by roller cooling machines of various thicknesses, reduce defects such as burrs and shearing misalignment, improve the plate shearing processing accuracy, and simplify the overall machine control logic and reduce equipment manufacturing costs.

[0016] 2. This invention achieves automatic feeding of sheet metal through a unidirectional meshing structure of ratchet and pawl. The feeding action and positioning components are linked, eliminating the need for additional independent feeding drive components. The mechanism can stably control the sheet metal feeding amount, effectively avoiding the problem of sheet metal slippage and deviation during the feeding stage, improving the continuity of shearing operations, simplifying the overall machine drive structure, reducing the number of parts used, and further controlling the production and manufacturing costs of the equipment.

[0017] 3. This invention uses multiple sets of guiding components to cooperate with each other to complete multi-directional guiding and limiting of the lifting and shearing action of the cutting blade, effectively reducing the vibration generated during the cutting operation and improving the overall stability of the blade operation. The electromagnet structure can magnetically lock the gap adjustment component to fix the adjusted cutting gap and prevent the cutting gap from shifting during the shearing process. The sliding fit structure can compensate for the displacement generated by the operation of the mechanism, ensuring the reliable and stable linkage action of the positioning component, further optimizing the cut quality after the plate is sheared and extending the service life of each component of the equipment.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figure 1-12The present invention provides the following technical solution: a plate shearing machine for producing a drum cooler, comprising an automatic feeding assembly 1; the automatic feeding assembly 1 includes an operating table 101, a cutting assembly 2 is provided on the top of the operating table 101, the cutting assembly 2 includes a cutting blade 201 provided above the operating table 101; a cutting gap adjusting assembly 3 is provided on the top of the operating table 101, the cutting gap adjusting assembly 3 includes a first straight pipe 301 provided above the operating table 101 and a second straight pipe 302 provided perpendicular to it, the first straight pipe 301 and the second straight pipe 302 are connected by a corrugated pipe; a first piston plate 303 is slidably connected to the inner wall of the first straight pipe 301, a first piston rod 304 is fixedly connected to the bottom of the first piston plate 303 through the first straight pipe 301, and a stop plate 30 for abutting the plate is fixedly connected to the bottom end of the first piston rod 304. 5; A second piston plate 306 is slidably connected to the inner wall of the second straight tube 302. A second piston rod 307 is fixedly connected to one side of the second piston plate 306, passing through the second straight tube 302. An iron block 308 is fixedly connected to one end of the second piston rod 307. A first spring sleeved on the second piston rod 307 is fixedly connected between the iron block 308 and the second straight tube 302. A push-pull plate 309 that slides with the cutting blade 201 is fixedly connected to the bottom of the iron block 308. A positioning component 4 is provided on the top of the operating table 101. The positioning component 4 includes two rotating plates 401. A rotating rod 402 is rotatably connected between the two rotating plates 401. A pressure block 403 that can be raised and lowered in the vertical direction is evenly arranged below the rotating rod 402. The pressure block 403 is raised and lowered to drive the push-pull plate 309 to move in the horizontal direction and adjust the cutting gap between the cutting blade 201 and the operating table 101.

[0023] The operation process of this embodiment is as follows: By controlling the pressure block 403 to move downward to press the plate, the pressure block 403 simultaneously drives the abutment plate 305 to move downward via the connecting plate, so that the abutment plate 305 presses against the plate. The reaction force of the plate drives the first piston plate 303 connected to the abutment plate 305 to move upward, squeezing the hydraulic oil between the first straight pipe 301 and the second straight pipe 302. The hydraulic oil pressure drives the second piston plate 306 to slide horizontally. The second piston plate 306 sequentially drives the second piston rod 307, the iron block 308 and the push-pull plate 309 to move. The push-pull plate 309 further drives the cutting blade 201 to complete the position adjustment. The equipment relies on the abutment plate 305 to move. 05 The displacement of the first piston plate 303 triggered by pressure can automatically adjust the cutting gap between the cutting blade 201 and the operating table 101 according to the actual thickness of the plate. This linkage mechanism integrates the plate clamping action and gap adjustment into one, without the need for additional detection elements and independent adjustment drives. The plate thickness is directly converted into a displacement signal of the hydraulic system, realizing adaptive adjustment of the cutting gap. This ensures that the plate is reliably clamped during the shearing operation, suppressing plate movement, and can be matched with roller coolers of different thicknesses to produce plates, avoiding burrs on the cut and shearing misalignment, improving the processing accuracy of the shearing, simplifying the control logic of the whole machine, and reducing the manufacturing cost of the equipment.

[0024] Example 2, please refer to Figure 1-12 This second embodiment is an improvement on the first embodiment as follows: the automatic feeding assembly 1 further includes a machine cover 102 fixedly connected to the top of the operating table 101. A control panel is installed on one outer side of the machine cover 102. A first sliding groove adapted to the sliding of the cutting assembly 2 is opened through the top of the machine cover 102. A second sliding groove is opened on both opposite sides of the first sliding groove. A movable plate 103 is symmetrically slidably connected to the top of the operating table 101. A plurality of ratchet teeth 104 are evenly fixedly connected to the top of the movable plate 103. A pusher plate 105 is fixedly connected between the two movable plates 103. A first guide groove that slides with the movable plate 103 is symmetrically opened on the top of the operating table 101. A second guide groove located outside the first guide groove is symmetrically opened on the top of the operating table 101. An L-shaped plate 106 is slidably connected to the inner wall of the second guide groove. A pawl 107 adapted to the ratchet teeth 104 is installed on one inner side of the L-shaped plate 106. A support plate 108 is hinged to an adjacent side of the L-shaped plate 106.

[0025] The operation process of this embodiment is as follows: When the equipment is running, the sheet material is placed on the table of the operating table 101. During the operation of the positioning component 4, the support plate 108 will swing. The support plate 108 pulls the L-shaped plate 106 to slide along the inside of the second guide groove. The pawl 107 mounted on the L-shaped plate 106 engages with the ratchet 104 on the top of the moving plate 103, thereby driving the moving plate 103 to slide forward along the first guide groove. The two moving plates 103 simultaneously drive the pusher plate 105 to push the sheet material forward. Automatic feeding of sheet metal is achieved; the machine cover 102 protects the internal cutting component 2, and the first and second sliding grooves on the machine cover 102 allow the cutting component 2 to slide and move. The control panel on the outside is used for setting the parameters and controlling the operation of the whole machine; when the support plate 108 swings back and drives the L-shaped plate 106 to move backward, the pawl 107 slides along the tooth surface of the ratchet 104, and the moving plate 103 and the pusher plate 105 remain in place, completing unidirectional gap feeding; relying on the unidirectional gap feeding of the ratchet 104 and the pawl 107... Automatic feeding of sheet metal is achieved through meshing. The feeding action and positioning component 4 are linked. The pawl 107 has a limiting function, which allows the pawl 107 to drive the moving plate 103 to move in one direction only. After the moving plate 103 drives the pusher plate 105 to move close to the cutting blade 211, the sheet metal is cut. Then, the limiting function of the pawl 107 is manually released, causing the pawl 107 to rotate out of the position of the ratchet 104, so that the pawl 107 does not interfere with the movement of the ratchet 104. Then, the pusher plate 105 is manually pushed away from the cutting blade 211, thereby completing the reset of the pusher plate 105. Finally, the pawl 107 is reset to the initial state to prepare for subsequent sheet metal feeding. No additional independent feeding drive component is required. The machine cover 102 can also prevent shearing debris from splashing outwards, which simplifies the equipment drive structure, reduces the cost of parts, and can stably control the sheet metal feeding amount, prevent the sheet metal from slipping and deviating during the feeding process, and improve the continuity of shearing operations and operational safety.

[0026] Example 3, please refer to Figure 1-12This third embodiment improves upon the first embodiment as follows: the cutting assembly 2 further includes a rectangular frame 202 that slides with the second slide groove. A hydraulic cylinder 203 is fixedly connected to the inner wall of the rectangular frame 202. A load-bearing plate 204 is fixedly connected to the output end of the hydraulic cylinder 203. Extension rods 205 are symmetrically fixedly connected to the bottom of the load-bearing plate 204. The two sets of extension rods 205 are fixedly connected to the cutting blade 201. A guide plate 206 that slides with the push-pull plate 309 is fixedly connected to one side of the cutting blade 201. First, the first limiting groove on the guide plate 206 has slots on both inner sides. The push-pull plate 309 has blocks that slide with the slots on both sides. This ensures that the cutting blade 211 will not interfere with the cutting gap adjustment assembly 3 during its up-and-down movement. At the same time, the cooperation between the slots and the blocks prevents the push-pull plate 309 from falling out of the first limiting groove during its movement in the direction perpendicular to the guide plate 206. A guide plate 206 has a slot on one side that slides with the push-pull plate 309. The first limiting groove of the moving fit, the cutting assembly 2 also includes two sets of guide rods 207 fixedly connected to the top of the machine cover 102. The outer wall of the guide rods 207 is slidably connected to an L-shaped slide plate 208. The top of the L-shaped slide plate 208 has a through notch 209. The notch 209 has a second limiting groove on both sides. The two second limiting grooves are slidably connected to a slider 210 fixedly sleeved on the extension rod 205. The two L-shaped slide plates 208 are fixedly connected to a baffle 211. The cutting gap adjustment assembly 3 is partially set in the middle of the cutting assembly 2, but the distance between the cutting blade 201 and the load-bearing plate 204 is much greater than the distance between the load-bearing plate 204 and the second straight tube 302 and the cutting blade 201 and the second straight tube 302. Therefore, it does not affect the normal cutting of the plate by the cutting blade 201. The cutting blade 201 is located below the cutting gap adjustment assembly 3, and the load-bearing plate 204 only serves a load-bearing function and does not directly affect the safety of the actual operation of the cutting blade 201.

[0027] The cutting gap adjustment assembly 3 also includes a first fixing plate 310 fixedly connected to the top of the machine cover 102. An electromagnet 311 that attracts the iron block 308 is fixedly connected to the bottom of the first fixing plate 310. Hydraulic oil is filled between the first straight tube 301 and the second straight tube 302. A connecting plate is fixedly connected to the outer wall of the first straight tube 301. A second fixing plate is fixedly connected between the second straight tube 302 and the machine cover 102. The positioning assembly 4 also includes a rotating shaft 404 rotatably connected inside the machine cover 102. The rotating shaft 404 is fixedly connected to the two rotating plates 401. A keyway 405 is provided through one side of the rotating plate 401. The keyway 405 is slidably connected to the rotating rod 402.

[0028] The operation process of this embodiment is as follows: During the cutting operation, the rectangular frame 202 slides along the second slide groove of the machine cover 102 to complete the overall position sliding. The hydraulic cylinder 203 drives the load-bearing plate 204 to move downward. The load-bearing plate 204 drives the cutting blade 201 to move downward through the extension rod 205 to perform cutting. The slider 210 on the extension rod 205 can slide in the second limiting groove of the L-shaped slide plate 208. The L-shaped slide plate 208 slides along the guide rod 207. The notch 209 provides movement avoidance space for the slider 210. The baffle 211 plays a role in limiting the feeding length of the plate, thereby ensuring that the size of each plate cut off is consistent. The guide plate 206 on the side of the cutting blade 201 The sliding cooperation between the first limiting groove and the push-pull plate 309 ensures smooth relative movement between the cutting blade 201 and the push-pull plate 309. When the cutting gap adjustment component 3 is working, the electromagnet 311 on the first fixed plate 310 can magnetically attract the iron block 308, which can lock the position of the iron block 308. The hydraulic oil filled inside the first straight tube 301 and the second straight tube 302 realizes pressure transmission. The connecting plate realizes the linkage of components. The second fixed plate completes the installation and fixation of the second straight tube 302. In the positioning component 4, the rotating shaft 404 drives the two rotating plates 401 to rotate. The rotating rod 402 can slide along the keyway 405 of the rotating plate 401 to adapt to the travel requirements of the mechanism.

[0029] This structure, through the cooperation of guide rod 207, L-shaped slide plate 208, and slider 210, provides multi-directional guidance and limit for the lifting and shearing action of the cutting blade 201, improving the operational stability of the cutting blade 201 and reducing shearing vibration. Electromagnet 311 can lock the position of iron block 308, fixing the adjusted cutting gap and preventing the gap from shifting during shearing. The sliding cooperation between keyway 405 and rotating rod 402 can compensate for the movement displacement of the mechanism, ensuring the reliable linkage action of positioning component 4, and improving the cutting quality of the sheet metal and the operational stability of the equipment.

[0030] Example 4, please refer to Figure 1-12This fourth embodiment improves upon the first embodiment as follows: the positioning component 4 further includes a mounting plate 406 fixedly connected inside the housing 102. A plurality of lifting rods 407 are evenly and slidably connected through the top of the mounting plate 406. A rectangular block 408, sleeved on the rotating rod 402, is fixedly connected to the top of each lifting rod 407. The lifting rod 407 slides in cooperation with the pressure block 403. A second spring, sleeved on the lifting rod 407, is fixedly connected between the mounting plate 406 and the pressure block 403. A cylindrical groove 409 is formed inside the pressure block 403, and a spring slidably connected to the inner wall of the cylindrical groove 409 is used for lifting rods. A circular plate 410 is fixedly connected to the rod 407, and a third spring is fixedly connected between the circular plate 410 and the cylindrical groove 409; a rectangular block 408 is fixedly connected to the connecting plate, and the rotating plate 401 is hinged to the support plate 108. The positioning assembly 4 also includes a power unit for driving the pressure block 403 to rise and fall. The power unit includes a motor 411 fixedly connected to the top of the machine cover 102. A first pulley 412 is fixedly connected to the output end of the motor 411, and a second pulley 413 is fixedly connected to the outer wall of the rotating shaft 404. A belt is connected between the first pulley 412 and the second pulley 413 for transmission.

[0031] The operation process of this embodiment is as follows: During operation, the motor 411 of the power unit drives the first pulley 412 to rotate, which drives the second pulley 413 and the rotating shaft 404 to rotate via belt transmission. The rotating shaft 404 drives the rotating plate 401 to swing. On the one hand, the rotating plate 401 drives the automatic feeding component 1 to complete the feeding action through the hinged support plate 108. On the other hand, the rotating plate 401 drives the rotating rod 402 to press down. The rotating rod 402 pushes the rectangular block 408 and the lifting rod 407 to move downward. The lifting rod 407 drives the circular plate 410 to slide in the cylindrical groove 409 of the pressure block 403, compressing the third spring and pushing the pressure block 403 to press the plate down. The second spring is compressed synchronously. At the same time, one of the rectangular blocks 408 drives the connecting plate to move, thereby driving the cutting gap adjustment component 3 to complete the adaptive adjustment of the cutting gap. When the motor 411 drives the rotating shaft 404 to rotate in the opposite direction, the rotating rod 402 is lifted, the second spring and the third spring release their elastic force, and push the pressure block 403 to reset and lift up, releasing the pressure on the plate.

[0032] The combination of the circular plate 410, the cylindrical groove 409, and the third spring can form a buffer to avoid damage to the workpiece and mechanism parts caused by hard squeezing when there are local deviations in the thickness of the plate. The entire mechanism can realize the plate clamping, cutting gap adjustment, and feeding linkage action simultaneously with a single motor 411, without the need for multiple independent power sources, simplifying the power configuration of the whole machine. The second and third springs realize the flexible clamping of the pressure block 403, which can not only ensure the plate clamping and positioning effect, but also play a buffering protection role for plates with uneven thickness. The timing of each action is matched with each other, improving the automation level of the equipment and reducing the energy consumption and manufacturing cost of the equipment.
