Description

Technical Field

[0001] This utility model relates to the field of metal sheet processing technology, and in particular to an adjustable cross-cutting machine for cold-rolled stainless steel sheets. Background Technology

[0002] Cold-rolled stainless steel sheet is an important basic material in modern industry and is widely used in construction, automobile manufacturing, electronics and precision instruments and other fields. In its processing, the cross-cutting process is the key link to achieve fixed-length cutting of sheet metal, which directly affects production efficiency and material utilization.

[0003] Traditional shearing machines mostly use a fixed blade structure, and the cutting length depends on a preset mold or mechanical limit, making it difficult to dynamically adjust according to actual needs. For example, when cutting different specifications of plates, operators need to manually change the mold or adjust the position of the mechanical baffle, which is not only time-consuming and labor-intensive, but also requires frequent machine stops and restarts, seriously affecting production efficiency. In addition, the adjustment range of the fixed blade is limited, and if the plate exceeds the design specifications, it is often difficult to complete the cutting, resulting in poor equipment applicability and difficulty in meeting the flexible production needs of modern manufacturing industries for multiple varieties and small batches. This limitation is particularly prominent in the processing of stainless steel plates, because the material has high hardness and high cost, and the generation of cutting errors or scrap will directly cause economic losses and waste of resources. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an adjustable cross-cutting machine for cold-rolled stainless steel sheets.

[0005] This utility model is achieved using the following technical solution: an adjustable cross-cutting machine for cold-rolled stainless steel sheets, comprising a processing base, side baffles fixedly connected to both sides of the upper surface of the processing base, a limit groove formed on the surface of the side baffles, an adjustment mechanism fixedly connected to the upper surface of the processing base, an elongated groove formed on the upper surface of the processing base, a side sliding groove formed on the inner wall of the elongated groove, an installation ring slidably connected inside the side sliding groove, a support plate fixedly connected to the inner wall of the processing base, a hydraulic rod fixedly connected to the surface of the support plate, a placement plate fixedly connected to the surface of the hydraulic rod, a negative pressure pump fixedly connected to the surface of the placement plate, and a negative pressure suction cup fixedly connected to the input end of the negative pressure pump;

[0006] The adjustment mechanism includes a motor base, a motor is fixedly connected to the surface of the motor base, a lead screw is fixedly connected to the output end of the motor, a right-angle bracket is threadedly connected to the surface of the lead screw, a mounting bracket is fixedly connected to the surface of the right-angle bracket, a sliding block is fixedly connected to the surface of the mounting bracket, a cylinder is fixedly connected to the upper surface of the mounting bracket, a blade holder plate is fixedly connected to the surface of the cylinder, a shearing blade is fixedly connected to the surface of the blade holder plate, and a guide groove is provided on the inner wall of the mounting bracket.

[0007] The above technical solution allows personnel to easily and flexibly adjust the position of the shearing blade according to actual shearing needs, thereby cutting steel plates of different lengths. The adjustment is simple and quick, without requiring too many steps. The negative pressure suction cup is used to adsorb and fix the steel plate, preventing the steel plate from moving during the shearing process, thus improving the shearing accuracy and stability. After shearing, the steel plate can be easily pushed out of the shearing area for easy collection by personnel, improving work efficiency.

[0008] As a further improvement to the above solution, the sliding block is slidably connected inside the limiting groove.

[0009] The above technical solution ensures the stability and accuracy of the mounting bracket movement, enabling the shearing blade to move accurately to the required position and improving shearing precision.

[0010] As a further improvement to the above solution, the tool holder plate is slidably connected to the inside of the guide groove.

[0011] As a further improvement to the above solution, the negative pressure suction cup is fixedly connected to the inside of the mounting ring.

[0012] The above technical solution enables the negative pressure suction cup to move smoothly in the side groove along with the mounting ring, ensuring the stability of the steel plate during the conveying and pushing process, and avoiding the steel plate position deviation or falling due to the unstable movement of the negative pressure suction cup.

[0013] As a further improvement to the above solution, limit rods extend through both sides of the placement plate.

[0014] As a further improvement to the above solution, one end of the limiting rod is fixedly connected to the inner wall of the processing base, and the other end of the limiting rod is fixedly connected to a shaft seat.

[0015] As a further improvement to the above solution, the bearing seat is fixedly connected to the inner wall of the machining base.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention uses a motor to drive a lead screw, which in turn moves a right-angle frame and a mounting frame. The mounting frame moves laterally along the limiting groove on the side baffle surface via a sliding block, thereby precisely adjusting the position of the shearing blade. Personnel can flexibly adjust the position of the shearing blade according to actual needs, thus cutting steel plates of different lengths. The adjustment is simple and quick, overcoming the limitations of traditional fixed-position shearing methods. It avoids the problem of limited cutting length and difficulty in meeting diverse needs caused by the fixed position of the shearing blade. Through the extension of the hydraulic rod, the placement plate and negative pressure suction cup push the cut steel plate out of the shearing area, making it convenient for operators to pick up and collect.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figure 1-4 An adjustable cross-cutting machine for cold-rolled stainless steel sheets according to this embodiment includes a processing base 1. Side baffles 2 are fixedly connected to both sides of the upper surface of the processing base 1. Limiting grooves 3 are opened on the surface of the side baffles 2. An adjustment mechanism 4 is fixedly connected to the upper surface of the processing base 1. An elongated groove is opened on the upper surface of the processing base 1. A side sliding groove 5 is opened on the inner wall of the elongated groove. An installation ring 6 is slidably connected inside the side sliding groove 5. A support plate 7 is fixedly connected to the inner wall of the processing base 1. A hydraulic rod 8 is fixedly connected to the surface of the support plate 7. A placement plate 9 is fixedly connected to the surface of the hydraulic rod 8. A negative pressure pump 10 is fixedly connected to the surface of the placement plate 9. A negative pressure suction cup 11 is fixedly connected to the input end of the negative pressure pump 10.

[0027] The adjusting mechanism 4 includes a motor base 401, a motor 402 fixedly connected to the surface of the motor base 401, a lead screw 403 fixedly connected to the output end of the motor 402, a right-angle bracket 404 threadedly connected to the surface of the lead screw 403, a mounting bracket 405 fixedly connected to the surface of the right-angle bracket 404, a sliding block 406 fixedly connected to the surface of the mounting bracket 405, a cylinder 407 fixedly connected to the upper surface of the mounting bracket 405, a tool holder plate 408 fixedly connected to the surface of the cylinder 407, and a tool holder plate 408 fixedly connected to the surface of the tool holder plate 408. A shearing blade 409 is fixedly connected. A guide groove 410 is provided on the inner wall of the mounting frame 405. When the adjustment mechanism is working, motor 402 drives the lead screw 403 to rotate. The lead screw 403 is threadedly connected to the right-angle frame 404, causing the right-angle frame 404 to move the mounting frame 405. The mounting frame 405 moves laterally along the limiting groove 3 on the surface of the side baffle 2 via a sliding block 406, thereby adjusting the position of the shearing blade 409. When the negative pressure pump 10 is working, it uses a negative pressure suction cup 11 to adhere and fix the steel plate to be sheared. The hydraulic rod 8 extends, driving the placement plate 9 and its surface, as well as the negative pressure pump 10 and negative pressure suction cup 11, to move. The negative pressure suction cup 11 is installed inside the mounting ring 6, which slides within the side sliding groove 5, conveying the steel plate to below the shearing blade 409. When the shearing blade 409 descends to shear, the negative pressure suction cup 11, being inside the mounting ring 6, will not cause damage to its surface. After shearing is completed, the hydraulic rod 8 continues to extend, pushing the adsorbed steel plate out of the shearing area.

[0028] The sliding block 406 is slidably connected to the inside of the limiting groove 3. The sliding block 406 slides inside the limiting groove 3, which plays a guiding and limiting role, so that the mounting bracket 405 can move laterally smoothly and accurately along the direction of the limiting groove 3, thereby realizing the precise adjustment of the position of the shearing blade 409.

[0029] The blade holder plate 408 is slidably connected to the inside of the guide groove 410. The guide groove 410 guides the movement of the blade holder plate 408, enabling the blade holder plate 408 to move smoothly in a predetermined direction, thereby ensuring that the shearing blade 409 can accurately reach the shearing position during the lifting and lowering process and complete the shearing action.

[0030] The negative pressure suction cup 11 is fixedly connected to the inside of the mounting ring 6. When the hydraulic rod 8 drives the negative pressure suction cup 11 to move, the mounting ring 6 slides in the side groove 5 to achieve the smooth movement of the negative pressure suction cup 11, thereby accurately conveying the adsorbed steel plate to the underside of the shearing blade 409 or pushing it out of the shearing area.

[0031] Limiting rods 12 pass through both sides of the placement plate 9.

[0032] One end of the limiting rod 12 is fixedly connected to the inner wall of the processing base 1, and the other end of the limiting rod 12 is fixedly connected to the bearing seat 13.

[0033] The bearing seat 13 is fixedly connected to the inner wall of the machining base 1.

[0034] The implementation principle of the adjustable cross-cutting machine for cold-rolled stainless steel sheet in this embodiment is as follows: The operator places the cold-rolled stainless steel sheet to be cut on the placement plate 9, starts the negative pressure pump 10, and firmly adsorbs and fixes the steel sheet through the negative pressure suction cup 11 to ensure that the steel sheet will not move during the cutting process, thereby ensuring the cutting accuracy. According to the required cutting length, the operator starts the motor 402, which drives the lead screw 403 to rotate. The lead screw 403 is threadedly connected to the right angle frame 404, which drives the right angle frame 404 to move. This causes the mounting frame 405 to move laterally along the limiting groove 3 on the surface of the side baffle 2 through the sliding block 406, precisely adjusting the position of the cutting blade 409 to reach the predetermined cutting start position. After adjusting the position of the cutting blade 409, the operator controls the hydraulic rod 8 to extend. The hydraulic rod 8 drives the placement plate 9 and its surface negative pressure pump 10 and negative pressure suction cup 11 to move smoothly along the direction of the limiting rod 12. The mounting ring 6 is installed inside the mounting ring 6, which slides within the side groove 5, thus accurately conveying the adsorbed steel plate directly below the shearing blade 409. Once the steel plate is accurately conveyed below the shearing blade 409, the operator activates the cylinder 407. The cylinder 407 pushes the blade holder plate 408 to descend smoothly along the guide groove 410 on the inner wall of the mounting frame 405. The shearing blade 409 descends accordingly to shear the steel plate. Since the negative pressure suction cup 11 is installed inside the mounting ring 6, the shearing blade 409 will not cause damage to its surface during the descent and shearing process, ensuring the normal operation and service life of the equipment. After shearing is completed, the operator controls the cylinder 407 to retract, causing the shearing blade 409 to rise and reset. Then, the operator continues to control the hydraulic rod 8 to extend, which drives the placement plate 9 and the negative pressure suction cup 11 to continue moving, pushing the sheared steel plate out of the shearing area for easy collection by the operator. At this time, the operator can turn off the negative pressure pump 10 to release the adsorption and fixation of the steel plate.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
