Description

Technical Field

[0001] This invention relates to the field of steel plate processing technology, specifically to a steel plate processing and cutting device for architectural hardware. Background Technology

[0002] Currently, in the processing of architectural hardware, it is often necessary to cut materials in order to carry out related processing. When cutting materials, mechanical cutting methods are usually used.

[0003] A steel plate cutting device with publication number CN222725573U includes a support leg, a base plate fixedly mounted above the support leg, a bracket mounted on the top surface of the base plate, a clamping part mounted above the bracket, a cutting part mounted on the left side of the clamping part, and a stacking part mounted on the left side of the cutting part. The clamping part includes a mounting plate, a first extension plate mounted on the outer side of the mounting plate, the inner side of the first extension plate being fixedly connected to the outer side of the mounting plate, and a first sliding rod mounted on the top surface of the first extension plate, the bottom surface of the first sliding rod being fixedly connected to the top surface of the first extension plate. By continuously pushing the steel plate on the mounting plate, the cut steel plate is pushed onto a lifting plate. A third motor is activated to control the rotation of a second threaded rod, pushing the lifting plate to slide on the surface of the third sliding rod, causing the lifting plate to move downward to receive the cut steel plate. This configuration allows for the placement of the steel plate.

[0004] In existing technologies, when cutting steel plates by rotating a disc cutter, the relative motion trajectory of the upper and lower blades on the shearing surface must ensure perpendicular cutting, that is, the blade plane should be perpendicular to the steel plate surface. However, uneven deformation / wear of the blade itself, insufficient rigidity of the equipment leading to force sway, or improper gap adjustment can cause the blade plane to be non-perpendicular to the steel plate surface, resulting in a tilted cut surface, increased burrs, or incomplete cutting, affecting the cutting quality. Furthermore, the accumulation of iron filings on the blade increases frictional resistance and local stress, accelerates blade wear or causes chipping, and reduces cutting stability.

[0005] Therefore, a steel plate processing and cutting device for architectural hardware is proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a steel plate processing and cutting device for building hardware, so as to solve the problem that when the blade plane is not perpendicular to the steel plate surface, it will cause the cutting section to be tilted, the burrs to increase or the cutting to be incomplete, which will affect the cutting quality.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a building hardware steel plate processing and cutting device, comprising a base plate and columns fixedly connected to the top of the base plate around the perimeter, wherein the top ends of the four columns are fixedly connected to the same top plate; Also includes: A cylinder is fixedly installed inside the top plate, and an installation frame is fixedly connected to the telescopic end of the cylinder. A cutting component is provided at the bottom of the installation frame, and a positioning component is provided at the top of the bottom plate.

A cutting blade is rotatably installed inside the movable seat, and an adjusting rod is slidably installed inside the movable seat. Four arc-shaped grooves are symmetrically opened at the bottom of the movable seat. The adjusting rods can slide inside the arc-shaped grooves, so that the lower ends of the multiple adjusting rods slide outward along the arc-shaped grooves. During the outward expansion of the lower ends, the adjusting rods contact the surface of the steel plate, forming lateral support for the movable seat to counteract the lateral force during cutting and keep the movable seat in a vertical state. The auxiliary unit includes two scrapers slidably mounted on the outside of the cutting blade, which are used to scrape and clean the iron filings on the outside of the cutting blade. The movable seat is equipped with a screw and nut mechanism that drives the adjusting rod to slide along the arc groove, and the adjusting rod is connected to the screw and nut mechanism through a spring telescopic rod, so that the adjusting rod can adaptively tighten and maintain support.

[0008] Preferably, two linear guide rails are fixedly installed horizontally and parallel inside the mounting frame. The output end of the linear guide rail is fixedly connected to a moving block. The bottom of the two moving blocks is fixedly connected to two moving seats respectively. Side strips are symmetrically fixedly connected to the outside of the moving seats. Two vertical rods are vertically slidably connected inside the side strips.

[0010] Preferably, the output end of the servo motor is fixedly connected to a rotating shaft, the cutting blade is fixedly connected to the outside of the rotating shaft, a bottom groove is provided in the middle of the bottom of the moving base, the cutting blade is located inside the bottom groove, a vertical plate is fixedly connected to the top of the mounting plate, a screw is rotatably connected inside the vertical plate, and a scraper is rotatably connected to the side of the screw near the cutting blade.

[0011] Preferably, a guide rod is slidably connected inside the vertical plate, the guide rod is fixedly connected to the scraper, a rotating rod is longitudinally rotatably installed on the inner top surface of the movable seat, and upper screws are fixedly connected to both ends of the rotating rod. A drive motor is fixedly installed on one side of the outer side of the movable seat, and the upper screw on one side passes through the movable seat and is fixedly connected to the output end of the drive motor. A sliding sleeve is threadedly connected to the outer side of the upper screw.

[0012] Preferably, a base rod is fixedly connected laterally inside the sliding sleeve, and two movable sleeves are slidably connected to the outside of the base rod. A second spring is sleeved on the outside of the base rod, and the two ends of the second spring are fixedly connected to the ends of the movable sleeves and the base rod, respectively. The bottom end of the movable sleeve is fixedly connected to the top end of the adjusting rod. The number of adjusting rods is the same as that of the movable sleeves, and a ball is fixedly installed at the bottom end of the adjusting rod through a spring telescopic rod.

[0013] Preferably, the positioning component includes a bent plate fixedly connected to both sides of the outer side of the base plate, a hydraulic rod fixedly installed on the top of the bent plate, a clamping plate fixedly connected to the telescopic end of the hydraulic rod, two horizontal bars fixedly connected to the top of the base plate, the clamping plate slidably connected to the horizontal bars, and a vertical groove vertically formed on the side of the clamping plate away from the hydraulic rod.

[0014] Preferably, a lower screw is vertically rotatably connected inside the abutment plate, and an inner block is threadedly connected to the outer side of the lower screw. The inner block is slidably connected to the vertical groove and fits against the inner wall of the vertical groove. A pressure plate is fixedly connected to the side of the inner block away from the abutment plate.

[0015] Preferably, a cutting groove is provided in the middle of the top of the base plate, and the cutting groove is horizontally opened.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up a cutting assembly and utilizing the cooperation of rollers and adjusting rods in the anti-sway support unit, after the steel plate is fixed, the moving seat will drive the cutting blade to move and cut the steel plate. The two opposing cutting blades will move linearly to cut, maintaining stable and sufficient cutting. At the same time as the moving seat moves, it will also synchronously drive the four adjusting rods on the outside of the moving seat to move. The adjusting rods move outward in an arc shape, which can help maintain the vertical state of the moving seat during the cutting process, thereby making the blade plane perpendicular to the surface of the steel plate, improving the cutting quality. At the same time, it can also assist in clamping and positioning the steel plate during cutting, reducing the cutting deviation of the steel plate. Furthermore, during cutting, the scraper in the auxiliary unit can simultaneously assist in cleaning the iron filings accumulated on the outside of the cutting blade, thereby reducing the obstruction to subsequent cutting and ensuring smooth cutting. The specific details are as follows: 1. By setting up the cutting assembly, after the steel plate is placed on top of the base plate and fixed, the cylinder is activated to extend. The cylinder drives the mounting frame and moving seat to descend. The linear guide rail drives the moving block and moving seat to move. The descent of the moving seat will drive the side strips and rollers to descend. The moving seat will also drive the adjusting rod to descend. The rollers first contact the top surface of the steel plate. Then, as the moving seat continues to descend, the vertical rod will slide inside the side strips. The top strip stretches the spring until the ball contacts the steel plate. The two moving seats move relative to each other. The servo motor drives the rotating shaft and the cutting blade to rotate. After the cutting blade on one side moves to cut, the cutting blade on the other side moves to cut again, maintaining the cutting... The system is stable and sufficient, and the drive motor starts working at the same time as cutting. The drive motor drives the upper lead screw and the rotating rod to rotate. The rotation of the rotating rod will drive the sliding sleeve to move. The two sliding sleeves move away from each other. The sliding sleeve drives the bottom rod to move. The bottom rod drives the moving sleeve and the adjusting rod to move. The adjusting rod slides inside the arc groove. The moving sleeve slides relative to the bottom rod and compresses the second spring to adapt to the movement of the adjusting rod along the arc groove. This can help maintain the vertical state of the moving seat at all times during the cutting process, so that the cutting plane is perpendicular to the surface of the steel plate, improving the cutting quality. At the same time, it can also assist in clamping and positioning the steel plate during cutting, reducing the cutting deviation of the steel plate. 2. By setting the cutting assembly, rotating the screw, the guide rod limits the position of the scraper. Rotating the screw will adjust the position of the scraper, so that the scraper is close to the cutting blade. The scraper and the outer side of the cutting blade maintain a gap of 0.5-1mm. Non-contact scraping and cleaning is adopted, which can remove iron filings on the outer side of the cutting blade without hindering the normal cutting use of the cutting blade, thus improving the cutting quality. 3. By setting up a positioning component, after the steel plate is placed on top of the base plate, the hydraulic rods on both sides are activated. The hydraulic rods extend and drive the clamping plates to move. The two clamping plates clamp and fix the steel plate on both sides. Then, the lower screw is rotated, which drives the inner block to descend. The inner block drives the pressure plate to descend, and the pressure plate presses and fixes the top surface of the steel plate, thereby keeping the steel plate stable and fixed during cutting, reducing cutting deviation and improving cutting quality.

[0023] The anti-sway support unit is a device that maintains the vertical state of the movable seat 43, consisting of an adjusting rod 425, an arc groove 426, and a related drive mechanism.

[0024] Inside the mounting frame 7, two linear guide rails 41 are fixedly installed horizontally in parallel. The output end of the linear guide rail 41 is fixedly connected to a moving block 42. The bottom of the two moving blocks 42 is fixedly connected to two moving seats 43 respectively. Side strips 44 are symmetrically fixedly connected to the outside of the moving seats 43. Two vertical rods 45 are vertically slidably connected inside the side strips 44.

[0025] The top of the two vertical rods 45 is fixedly connected to the same top bar 46. A spring 47 is sleeved on the outside of the vertical rod 45. The two ends of the spring 47 are fixedly connected to the side bar 44 and the top bar 46 respectively. Damping blocks are provided at both ends of the spring 47 to reduce its reciprocating vibration and maintain stable telescopic use. A roller 48 is fixedly installed at the bottom of the vertical rod 45. Two mounting plates 49 are fixedly connected to the middle of the inner bottom surface of the moving base 43. A servo motor 410 is fixedly installed on the inner side of the mounting plate 49.

[0026] The auxiliary unit includes two scrapers 416 that are slidably mounted on the outside of the cutting blade 412. The scrapers 416 are used to scrape and clean the iron filings on the outside of the cutting blade 412. The position of the scrapers 416 can be flexibly adjusted, which improves the convenience of cleaning.

[0027] The output end of the servo motor 410 is fixedly connected to the rotating shaft 411, and the cutting blade 412 is fixedly connected to the outside of the rotating shaft 411. The bottom of the moving base 43 has a bottom groove 413 in the middle, and the cutting blade 412 is located inside the bottom groove 413 to maintain the stable cutting of the cutting blade 412. The top of the mounting plate 49 is fixedly connected to the vertical plate 414, and the inside of the vertical plate 414 is rotatably connected to the screw 415. The side of the screw 415 near the cutting blade 412 is rotatably connected to the scraper 416.

[0028] Inside the vertical plate 414, a guide rod 417 is slidably connected. The guide rod 417 is fixedly connected to the scraper 416. A rotating rod 418 is longitudinally rotatably installed on the inner top surface of the movable seat 43. Both ends of the rotating rod 418 are fixedly connected to upper screw rods 419. A drive motor 420 is fixedly installed on one side of the outer side of the movable seat 43. One side of the upper screw rod 419 passes through the movable seat 43 and is fixedly connected to the output end of the drive motor 420. A sliding sleeve 421 is threadedly connected to the outer side of the upper screw rod 419.

[0029] The sliding sleeve 421 is laterally fixedly connected to a base rod 422. Two movable sleeves 423 are slidably connected to the outside of the base rod 422. A second spring 424 is sleeved on the outside of the base rod 422. The two ends of the second spring 424 are fixedly connected to the ends of the movable sleeves 423 and the base rod 422, respectively. Damping blocks are provided at both ends of the second spring 424 to reduce its reciprocating vibration and maintain stable telescopic use. The bottom end of the movable sleeve 423 is fixedly connected to the top end of the adjusting rod 425. The number of adjusting rods 425 is the same as that of the movable sleeves 423. A ball 427 is fixedly installed at the bottom end of the adjusting rod 425 through a spring telescopic rod.

[0030] Example 1: As Figure 3 - Figure 10 As shown, by extending the cylinder 6, the cylinder 6 drives the mounting frame 7 and the movable seat 43 to descend. The linear guide rail 41 drives the movable block 42 and the movable seat 43 to move. The descent of the movable seat 43 will drive the side bar 44 and the roller 48 to descend. The movable seat 43 will also drive the adjusting rod 425 to descend. The roller 48 first contacts the top surface of the steel plate. Then, as the movable seat 43 continues to descend, the vertical rod 45 will slide inside the side bar 44. The top bar 46 stretches the spring 47 until the ball 427 contacts the steel plate, and the two movable seats 43 move relative to each other.

[0031] Servo motor 410 drives rotating shaft 411 and cutting blade 412 to rotate. After one side of cutting blade 412 moves to cut, the other side of cutting blade 412 moves to cut again, maintaining stable and sufficient cutting. At the same time as cutting, drive motor 420 is started to work. Drive motor 420 drives upper lead screw 419 and rotating rod 418 to rotate. The rotation of rotating rod 418 will drive sliding sleeve 421 to move. The two sliding sleeves 421 move away from each other. Sliding sleeve 421 drives bottom rod 422 to move. Bottom rod 422 drives moving sleeve 423 and adjusting rod 425 to move. Adjusting rod 425 slides inside arc groove 426. Moving sleeve 423 slides relative to bottom rod 422 and compresses spring 424 to adapt to the movement of adjusting rod 425 along arc groove 426.

[0032] It can help maintain the vertical position of the moving seat 43 during the cutting process, so that the blade plane is perpendicular to the steel plate surface, thus improving the cutting quality. At the same time, it can also assist in clamping and positioning the steel plate during cutting, reducing the cutting deviation of the steel plate.

[0033] By rotating the screw 415, the guide rod 417 limits the position of the scraper 416. Rotating the screw 415 will adjust the position of the scraper 416, so that the scraper 416 is close to the cutting blade 412. The scraper 416 and the outer side of the cutting blade 412 maintain a gap of 0.5-1mm. Non-contact scraping and cleaning is adopted, which can remove iron filings on the outer side of the cutting blade 412 without hindering the normal cutting use of the cutting blade 412, thus improving the cutting quality.

[0034] like Figure 1 and Figure 11 - Figure 12 As shown, a positioning component 5 is provided on the top of the base plate 1. The positioning component 5 includes a bent plate 51 fixedly connected to both sides of the outside of the base plate 1. A hydraulic rod 52 is fixedly installed on the top of the bent plate 51. A clamping plate 54 is fixedly connected to the telescopic end of the hydraulic rod 52. There are at least two hydraulic rods 52. The clamping plate 54 on the same side is fixedly connected to the output end of the hydraulic rod 52.

[0035] Two horizontal bars 53 are fixedly connected to the top of the base plate 1. The abutment plate 54 is slidably connected to the horizontal bars 53. A vertical groove 55 is vertically opened on the side of the abutment plate 54 away from the hydraulic rod 52.

[0036] The inner side of the clamping plate 54 is vertically rotatably connected to a lower screw 56. The outer side of the lower screw 56 is threadedly connected to an inner block 57. The inner block 57 is slidably connected to the vertical groove 55 and fits against the inner wall of the vertical groove 55. A pressure plate 58 is fixedly connected to the side of the inner block 57 away from the clamping plate 54.

[0037] A cutting groove 8 is also provided in the middle of the top of the base plate 1. The cutting groove 8 is horizontally opened.

[0038] Example 2: Figure 11 - Figure 12 As shown, after the steel plate is placed on top of the base plate 1, the hydraulic rods 52 on both sides are activated. The hydraulic rods 52 extend and drive the clamping plates 54 to move. The two clamping plates 54 clamp and fix the two sides of the steel plate. Then, the lower screw 56 is rotated, and the lower screw 56 drives the inner block 57 to descend. The inner block 57 drives the pressure plate 58 to descend. The pressure plate 58 presses and fixes the top surface of the steel plate, thereby maintaining the stability and fixation of the steel plate during cutting, reducing cutting deviation, and improving cutting quality.

[0039] Working principle: When using this device, firstly, as... Figure 1 - Figure 12 As shown, after the steel plate is placed on top of the base plate 1 and fixed, the cylinder 6 is extended. The cylinder 6 drives the mounting frame 7 and the moving seat 43 to descend. The linear guide rail 41 drives the moving block 42 and the moving seat 43 to move. The rotating rod 418 first contacts the top surface of the steel plate, and the vertical rod 45 slides inside the side bar 44 until the ball 427 contacts the steel plate. The two moving seats 43 move relative to each other. The servo motor 410 drives the rotating shaft 411 and the cutting blade 412 to rotate. After the cutting blade 412 on one side moves to cut, the cutting blade 412 on the other side moves to cut again, maintaining stable and sufficient cutting. At the same time as cutting, the drive motor 420 is started to work. The drive motor 420 drives the upper lead screw 419 and the rotating rod 418 to rotate. The rotation of the rotating rod 418 will drive the sliding sleeve 421 to move. The two sliding sleeves 421 move away from each other. The sliding sleeve 421 drives the bottom rod 422 to move. The bottom rod 422 drives the moving sleeve 423 and the adjusting rod 425 to move. The adjusting rod 425 slides inside the arc groove 426. The adjusting rod 425 drives the moving sleeve 423 to move on the bottom rod 422. The moving sleeve 423 will also compress the second spring 424, thereby synchronously driving the four adjusting rods 425 to move. The adjusting rods 425 move outward in an arc shape, so that the cutting edge plane is perpendicular to the steel plate surface, improving the cutting quality.
