Description

A block metal strip cutting machine Technical Field

[0001] This utility model belongs to the field of industrial processing equipment technology, and specifically relates to a block metal strip cutting machine. Background Technology

[0002] In modern industrial production, bulk metal cutting is a crucial metal processing step, undertaking the important task of transforming bulk metal materials into strips of specific sizes and shapes. This process requires careful selection of suitable cutting equipment based on the precise specifications and accuracy standards of the strips. For example, sawing machines, with their mechanical cutting method, are suitable for general precision requirements; laser cutting machines achieve high-precision cutting using high-energy laser beams; and plasma cutting machines achieve efficient cutting of various metals through high-temperature plasma arcs. After selecting the equipment, the bulk metal is firmly fixed onto the processing equipment. The equipment cuts the metal according to a pre-set cutting path, using methods such as tool cutting, laser beam melting, or plasma arc melting. Throughout the cutting process, precise control of cutting speed, feed rate, and various cutting parameters is particularly critical, as this directly affects the dimensional accuracy and surface quality of the strips, thus influencing the performance and quality of subsequent products. Due to its indispensability, bulk metal cutting is widely used in many core fields such as machinery manufacturing, construction, automobiles, and electronics, providing fundamental and crucial strip metal raw materials for the subsequent processing and product manufacturing of these industries.

[0003] With the continuous advancement of technology, various types of block metal slicing machines have emerged. For example, the block metal slicing machine disclosed in Chinese Patent No. CN207770952U has a structure that includes a slicing box, support legs, a worktable, a belt conveyor, a cam, a motor, a guide sleeve, a transmission ball, a transmission rod, a fixing plate, a mounting plate, a slicing blade, a mounting base, and connecting springs. This slicing machine uses support legs to stably support the slicing box. The belt conveyor is set inside the slicing box to transport materials. The worktable carries the motor, and the motor drives the cam to rotate. The transmission principle of the cam is applied, enabling multi-segment cutting with one energy consumption, which improves the slicing efficiency to a certain extent and saves manpower and material resources.

[0004] However, a deeper examination of the device's performance in practical applications reveals its limitations. Firstly, the use of belt conveyors to transport metal materials has inherent shortcomings. Due to the soft texture of the belt and the hard texture of the metal, the belt is prone to deformation during the punching and cutting process due to the heavy pressure and cutting force of the metal. This deformation directly leads to deviations in the cutting position, resulting in a large number of defective products and seriously affecting production efficiency and product quality. Secondly, the fixed spacing between the cutters at the top of the strip cutter lacks a flexible adjustment mechanism. When facing diverse production needs, such as cutting strips of metal of different sizes, the cutter spacing cannot be easily adjusted, greatly limiting the applicability of the equipment and making it difficult to meet the urgent needs of modern industrial production for efficient, precise, and flexible processing. Therefore, it is necessary to develop a new type of block metal strip cutting equipment to overcome the shortcomings of the existing equipment. Summary of the Invention

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a block metal strip cutting machine to solve the problems of the inability to adjust the cutting blade spacing and the poor stability of the bottom cutting support during the application of the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A block metal strip cutting machine includes a base, on which support legs are fixedly installed in a linear arrangement at equal intervals on both sides of the top of the base, a top seat is fixedly installed on the top of the support legs, a strip cutting mechanism is fixedly installed on the rear side of the top of the top seat, and a positioning mechanism is fixedly installed on the front side of the top of the top seat.

[0008] The positioning mechanism includes a first motor, which is fixedly installed at the bottom front end of the top base. The output end of the first motor passes through the top base and is fixedly installed with a rotating platform. Positioning components are fixedly installed at equal intervals on the outer surface of the rotating platform. The bottom of the positioning components is in contact with the top of the top base.

[0009] As a preferred technical solution, the positioning component includes a receiving plate, which is fixedly installed at equal intervals on the outside of the rotary table. A side rail is fixedly installed on the outer end of the receiving plate. A lead screw is rotatably connected inside the side rail. The two ends of the lead screw have opposite thread directions. A slider is threaded to both ends of the lead screw. A clamping frame is fixedly installed on the top of the slider. A second motor is fixedly installed on one end of the side rail. The output end of the second motor is connected to the end of the lead screw.

[0010] As a preferred technical solution, the bottom of the receiving plate is rotatably connected with balls at equal intervals, and the top of the balls is fitted and connected to the top of the top seat.

[0011] As a preferred technical solution, the cutting mechanism includes a frame, which is fixedly installed on the top rear side of the top seat. An electric push rod is fixedly installed on the top of the frame, and an adjustment component is fixedly installed through the output end of the electric push rod through the frame. A punching knife is fixedly connected at equal intervals to the bottom of the adjustment component.

[0012] As a preferred technical solution, the adjustment component includes a base plate, which is fixedly installed at the bottom output end of the electric push rod. Mounting rails are fixedly installed on both sides of the base plate. Sliding blocks are slidably connected at equal intervals inside the mounting rails. A fixing plate is fixedly installed at the bottom of the sliding blocks. The punching knife is fixedly installed at the bottom of the fixing plate. A fixing arm is fixedly installed on the top outer side of the fixing plate. A mounting screw is threaded to the upper end of the fixing arm, and the end of the mounting screw passes through the fixing arm.

[0013] As a preferred technical solution, the mounting screw is configured as a hand-tightening screw, and the mounting rail has limit holes arranged linearly at equal intervals on the side near the mounting screw, and the end of the mounting screw is inserted into the limit hole.

[0014] As a preferred technical solution, the cross-sectional shape of the internal cavity of the mounting rail and the internal cavity of the side rail are both set to a convex shape, and the side shape of the sliding block and the slider is also set to a convex shape.

[0015] In summary, the present invention has the following main advantages:

[0016] First, this device, by setting up a positioning mechanism, can effectively improve the stability and efficiency of block metal strip processing during use. In use, the operator places the metal block to be processed on the top of the receiving plate, starts the second motor, and the motor drives the lead screw to rotate. Because the threads at both ends of the lead screw rotate in opposite directions, they drive the two sliders connected to it to slide relative to each other or in opposite directions, thereby causing the clamping frame to move synchronously and accurately clamp and fix the metal block. It can flexibly adapt to metal blocks of different sizes. During strip processing, the electric push rod is started to push the punching knife down to cut. The receiving plate provides stable support. At the same time, the first motor is started to drive the rotary table to rotate, so that the metal block reciprocates and rotates. With the electric push rod punching, automated cyclic cutting is realized, improving processing efficiency and stability.

[0017] Secondly, by incorporating a cutting mechanism, this device can further enhance its adaptability during use. After the metal block is fixed by the positioning mechanism, the electric push rod can be activated, causing the punching blade to move downwards and punch the metal block. Multiple sets of equally spaced punching blades can cut multiple metal strips at once, improving processing efficiency. If the size of the cut metal strips needs to be adjusted, the sliding block inside the mounting rail can be adjusted to change the spacing of the punching blades on the base plate, meeting different cutting requirements. After adjustment, the hand-tightening screw on the mounting rail is twisted to insert into the limiting hole, fixing the sliding block and the punching blade. When the size of the metal block does not match the existing punching blade, a suitable punching blade can be removed and replaced, facilitating flexible adjustment and improving the ease of use of the device.

[0024] Example

[0025] Referring to Figures 1 to 5, a block metal strip cutting machine of this embodiment includes a base 1, support legs 2 are fixedly installed on both sides of the top of the base 1 in a linear arrangement at equal intervals, a top seat 4 is fixedly installed on the top of the support legs 2, a strip cutting mechanism 3 is fixedly installed on the rear side of the top of the top seat 4, and a positioning mechanism 5 is fixedly installed on the front side of the top of the top of the top seat 4.

[0026] The positioning mechanism 5 includes a first motor 51, which is fixedly installed at the bottom front end of the top seat 4. A rotating table 52 is fixedly installed through the top seat 4 at the output end of the first motor 51. Positioning components 53 are fixedly installed at equal intervals on the outer surface of the rotating table 52. The bottom of the positioning components 53 is fitted and connected to the top of the top seat 4. In this block metal strip cutting machine, the base 1 provides stable support for the overall structure, and the linearly arranged support legs 2 on both sides of its top further stabilize the structure, lifting the top seat 4 to a suitable height. The positioning mechanism 5 plays a crucial role in the cutting machine's workflow. During operation, the first motor 51, installed at the bottom front end of the top seat 4, starts, and the motor output rotates... The rotary table 52 connected to it operates synchronously. The positioning components 53, which are fixed at equal intervals on the rotary table 52, move to the working position in sequence as the rotary table 52 rotates. When it is necessary to process block metal, the metal block is placed on the positioning component 53. The bottom of the positioning component 53 is in close contact with the top of the top seat 4 to ensure stable positioning. According to its own structural design, the positioning component 53 can accurately position and clamp metal blocks of different sizes, laying the foundation for the subsequent processing operation of the cutting mechanism 3. During the cutting process, the rotation of the rotary table 52 can drive the positioned metal block to move along the preset path, and cooperate with the cutting mechanism 3 to complete the efficient block metal cutting processing task.

[0027] Referring to Figures 1-3 and 5, the positioning component 53 includes a receiving plate 531, which is fixedly installed at equal intervals on the outside of the rotary table 52. A side rail 532 is fixedly installed at the outer end of the receiving plate 531. A lead screw 533 is rotatably connected inside the side rail 532. The two ends of the lead screw 533 have opposite thread directions, and both ends of the lead screw 533 are threadedly connected to sliders 534. A clamping frame 535 is fixedly installed on the top of the slider 534. A second motor 536 is fixedly installed at one end of the side rail 532. The output end of the second motor 536 is connected to the end of the lead screw 533. Ball bearings 537 are rotatably connected at equal intervals at the bottom of the receiving plate 531. The tops of the ball bearings 537 are in contact with the top of the top seat 4. When the positioning component 53 of this block metal cutting machine is working, the receiving plate 531 serves as the base component for placing the metal block to be processed, and is installed at equal intervals on the outside of the rotary table 52. When it is necessary to adjust the positioning component 53, the positioning component 531 can be adjusted accordingly. When the metal block is positioned, the second motor 536 at one end of the side rail 532 is started. Its output end drives the lead screw 533 connected to it to rotate. Since the threads at both ends of the lead screw 533 turn in opposite directions, the rotation of the lead screw 533 will cause the slider 534 connected by the threads at both ends to slide in opposite directions within the side rail 532. The clamping frame 535 fixed on the top of the slider 534 moves accordingly. When the two clamping frames 535 move towards each other, the metal block placed on the receiving plate 531 can be clamped and fixed. At the same time, the ball bearings 537 rotatably connected at equal intervals at the bottom of the receiving plate 531 are in contact with the top of the top seat 4. When the rotating table 52 drives the receiving plate 531 to rotate, the ball bearings 537 can reduce the friction between the receiving plate 531 and the top seat 4, making the positioning component 53 rotate more smoothly and ensuring that the positioning component 53 can stably and flexibly position the metal block for subsequent strip cutting operations.

[0028] Referring to Figures 1-4, the cutting mechanism 3 includes a frame 31, which is fixedly installed on the top rear side of the top seat 4. An electric push rod 32 is fixedly installed on the top of the frame 31. An adjusting assembly 33 is fixedly installed through the frame 31 at the output end of the electric push rod 32. A punching knife 34 is fixedly connected at equal intervals to the bottom of the adjusting assembly 33. The adjusting assembly 33 includes a base plate 331, which is fixedly installed on the bottom output end of the electric push rod 32. Mounting rails 33 are fixedly installed on both sides of the base plate 331. 2. Sliding blocks 333 are slidably connected at equal intervals inside the mounting rail 332. A fixing plate 334 is fixedly installed at the bottom of the sliding block 333. The punching blade 34 is fixedly installed at the bottom of the fixing plate 334. A fixing arm 335 is fixedly installed on the outer top of the fixing plate 334. A mounting screw 336 is threadedly connected to the upper end of the fixing arm 335. The end of the mounting screw 336 passes through the fixing arm 335. In this block metal cutting machine, the cutting mechanism 3 is responsible for cutting the positioned block metal into strips. During operation, the positioning mechanism 5 precisely positions the metal block in the appropriate position. Then, the electric push rod 32 at the top of the frame 31 is activated, and its output end extends downward, driving the connected adjustment component 33 to move down. The punching blade 34 at the bottom of the adjustment component 33 then approaches the metal block. When the electric push rod 32 continues to push, the punching blade 34 can punch the metal block and cut it into strips. To adjust the width of the cut metal strips, it can be achieved through the adjustment component 33. The sliding block 333 in the mounting rail 332 can slide within it. Since the punching blade 34 is connected to the sliding block 333 through the fixing plate 334, the sliding block 333 can drive the punching blade 34 to move when it slides, thereby changing the distance between adjacent punching blades 34. After the distance is adjusted, the mounting screw 336 on the fixing arm 335 is twisted so that its end is inserted into the corresponding limiting hole 337, which can fix the position of the sliding block 333 and the punching blade 34, ensuring the stability of the cutting process. In this way, the strip cutting mechanism 3 can flexibly adapt to different strip cutting needs.

[0029] Referring to Figure 4, the mounting screw 336 is a hand-tightening screw. Limiting holes 337 are linearly arranged at equal intervals on the side of the mounting rail 332 near the mounting screw 336. The end of the mounting screw 336 is inserted into the limiting hole 337. The internal cavity of the mounting rail 332 and the internal cavity of the side rail 532 are both convex in cross-sectional shape. The side shapes of the sliding block 333 and the slider 534 are also convex in shape. In the strip cutting mechanism 3 of this strip cutting machine, the limiting holes 337 linearly arranged on the side of the mounting rail 332 near the mounting screw 336 cooperate with the hand-tightening mounting screw 336, playing a crucial role in adjustment and fixation. When it is necessary to adjust the spacing of the punching blades 34 to meet different metal strip cutting size requirements, because the internal cavity of the mounting rail 332 is convex in shape, the matching convex-shaped sliding block 333 can slide smoothly within the mounting rail 332. The sliding block 333 drives the bottom fixing plate 334 and the punching blades 34 fixed thereon to move, completing the spacing adjustment. After adjustment, the operator manually tightens the installation screw 336. Being hand-tight, this is convenient. The end of the screw is inserted into the corresponding limiting hole 337 to fix the sliding block 333, thereby stabilizing the position of the cutting blade 34 and ensuring that the spacing between the cutting blades 34 remains constant during cutting. Similarly, the internal cavity of the side rail 532 and the side of the slider 534 have a convex design, ensuring stable sliding of the slider 534 within the side rail 532. In the positioning assembly 53, the slider 534 drives the clamping frame 535 to move precisely, achieving stable clamping of metal blocks of different sizes and providing a reliable positioning basis for strip cutting.

[0030] Operating principle and advantages: The positioning mechanism 5 equipped in this device greatly enhances the stability and efficiency in the process of cutting block metal strips. During the operation of the device, the operator places the metal block to be processed on the top of the receiving plate 531 and then starts the second motor 536. The motor drives the lead screw 533 to rotate. The threads at both ends of the lead screw 533 turn in opposite directions. Its rotation causes the two sliders 534 connected to it to slide back and forth relative to each other or in opposite directions. The sliding of the sliders 534 drives the clamping frame 535 connected to them to move synchronously. When the two clamping frames 535 move inward, they can accurately clamp and fix the metal block. This design of the positioning component 53 can flexibly clamp metal blocks of different sizes and specifications in the center, effectively ensuring the stability of the metal block during the processing.

[0031] During the strip cutting stage, the electric push rod 32 is activated. The operation of the electric push rod 32 pushes the punching knife 34 downward to realize the strip cutting operation of the metal block. At the same time, the receiving plate 531 provides stable and reliable support for the metal block during the cutting process, ensuring the smooth progress of the cutting process. To further improve the processing efficiency, the first motor 51 can be activated to drive the rotary table 52 to rotate. The rotation of the rotary table 52 can realize the reciprocating rotational displacement of each metal block. Combined with the extension and retraction of the electric push rod 32, the punching operation is carried out, realizing a stable punching process with limited positioning. The entire positioning mechanism 5 and the strip cutting process work together to realize an automated reciprocating cyclic cutting processing mode, which significantly improves the stability and processing efficiency of the overall strip cutting of this device and greatly facilitates the actual use of the device.

[0032] The strip cutting mechanism 3 provides the device with high flexibility and adaptability in the strip cutting process. After the metal block is positioned by the positioning component 53 of the positioning mechanism 5, the electric push rod 32 is activated. The electric push rod 32 pushes the punching knife 34 downward to perform punching operation on the metal block. The punching knife 34 in this device adopts a multi-group design with equal spacing, which can cut the metal block into multiple metal strips at one time, greatly improving the overall punching efficiency of the device.

[0033] When the size of the cut metal strips needs to be adjusted according to actual production requirements, this can be achieved by adjusting the spacing of the punching blades 34. Specifically, the sliding block 333 inside the mounting rail 332 is slidable. The movement of the sliding block 333 changes the position of each punching blade 34 at the bottom of the base plate 331, thus allowing for flexible adjustment of the spacing between the punching blades 34. Operators can precisely adjust the spacing of the punching blades 34 according to specific cutting requirements to adapt to cutting metal blocks into metal strips of different sizes. After adjustment, simply twist the mounting screw 336 to insert it into the limiting hole 337 to fix the sliding block 333 inside the mounting rail 332, thereby completing the fixing operation of the punching blades 34. The mounting screw 336 in this device is designed as a hand-tight screw, ensuring convenience during adjustment while effectively guaranteeing the stability of subsequent cutting processes.

[0034] Furthermore, if the size of the metal block is incompatible with the existing punching blade 34 during the cutting process, the operator can pull out the mounting screw 336 from the limiting hole 337, thereby removing the sliding block 333 and its base plate 331 from the bottom of the mounting rail 332. Then, the matching punching blade 34 is taken out, the sliding block 333 on the punching blade 34 is inserted into the mounting rail 332, and the mounting screw 336 is twisted to limit and fix it. This design allows the device to be flexibly adapted and adjusted during the overall use, further improving the overall ease of use of the device.
