Description

Technical Field

[0001] The present invention relates to the technical field of metal cutting instruments, and particularly to a multi-segment metal cutting tool assembly. Background Art

[0002] Currently, in the multi-segment cutting process of metal sheets, a cutting device with a multi-blade arrangement is often used to achieve simultaneous cutting. In a traditional metal cutting tool assembly, multiple cutting tools are generally installed on a bracket at a fixed spacing, and synchronous cutting is achieved through a unified driving mechanism during the cutting process. However, such a structure has great limitations: On the one hand, the cutting tool spacing in the traditional structure is usually a fixed and non-adjustable structure, making it difficult to flexibly adjust the tool layout according to plates with different widths or different cutting paths. When the processing task changes, it is often necessary to replace the whole or re-arrange the position of the cutting tool holder, resulting in a long debugging cycle and low operation efficiency, seriously affecting the flexible processing ability of the industrial site.

[0003] On the other hand, the existing metal cutting tool system usually adopts a rigid fixed vertical downward pressing method, only supporting a vertical cutting path, and unable to achieve fine adjustment of the cutting tool angle or inclined cutting operation. When facing special-shaped plates or the need for an inclined cutting process, the existing device often cannot meet the accurate cutting path positioning requirements, restricting its adaptability in diverse processing scenarios.

[0004] In addition, due to the lack of a tool angle locking and adjusting mechanism in the traditional structure, the vibration or stress fluctuation during the cutting process is likely to cause the deviation of the cutting tool angle, further affecting the cutting accuracy and stability. Therefore, how to design a multi-segment metal cutting tool assembly with adjustable cutting tool spacing, controllable angle and stable operation has become a problem that the industry urgently needs to break through. In view of this, research and improvement are carried out on the existing problems, and a multi-segment metal cutting tool assembly is provided to solve the existing problems, aiming to achieve the purpose of solving problems and improving practical value through this technology.

[0023] Below in conjunction with the attached Figures 1-7 Describe a multi-segment metal cutting tool assembly provided by some embodiments of the present invention. Embodiment 1:

[0025] Vertical rods 110 are provided at both ends of the top surface of the cutting table 100. A sliding sleeve table 120 is slidably sleeved on the surface of the vertical rods 110. A rack-shaped tooth rod 121 is connected between the two sliding sleeve tables 120. The tooth rod 121 serves as the sliding track and driving reference for multiple adjustment slider groups 200.

[0026] A plurality of adjusting slide groups 200 can be independently slidably sleeved on the surface of the truss tooth rod 121. The adjusting slide group 200 includes a slide table 210 and an adjusting drive motor 220 fixed on the surface of the slide table 210. The output end of the adjusting drive motor 220 is connected with a worm gear shaft 221. A slide seat 211 is arranged on the surface of the slide table 210, and a traveling wheel 222 meshingly driven with the worm gear shaft 221 is rotatably installed. The main body of the slide seat 211 is slidably connected with the truss tooth rod 121, and the traveling wheel 222 meshes with the rack-structured truss tooth rod 121, realizing the precise movement of the adjusting slide group 200 on its surface, and is used for adjusting the horizontal position and the slitting distance between each group of rudder platforms and the cutting assembly.

[0027] The rudder platform group 300 is installed on the upper surface of the slide table 210, and mainly includes a shaft disc seat 310, a transmission key shaft 320 and a drive motor 330 arranged on the top surface of the slide table 210. The transmission key shaft 320 is rotatably installed in the shaft disc seat 310, and the output end of the drive motor 330 is meshingly driven with the transmission key shaft 320 to realize the drive thereof. The structure of the rudder platform group 300 allows the cutting assembly to perform angle adjustment around the vertical direction, and the shaft disc seat 310 is provided with a rotation damping mechanism and manual adjustment control through structural design to prevent angle drift.

[0028] The cutting assembly 400 is installed on the surface of the lower bearing frame 311 of the rudder platform group 300. The cutting assembly includes a cutter disc 410 and a tooth disc seat 420. The cutter disc 410 is rotatably installed on the bearing frame 311 and meshes with the output end of the transmission key shaft 320; the tooth disc seat 420 is structurally matched with the cutter disc 410, and a plurality of convex teeth are arranged on its surface, and a socket groove meshing with the convex teeth is opened on the inner wall of the cutter disc 410, which is used for realizing quick positioning and disassembly and is convenient for replacing tools or maintenance.

[0029] Further, a lead screw assembly 111 is provided at the top end of the vertical rod 110. The lead screw assembly 111 can drive the sliding sleeve table 120 to perform lifting movement on the surface of the vertical rod 110, so as to integrally adjust the height of the truss tooth rod 121 to adapt to different thickness plates or multiple working conditions.

[0030] Preferably, the number of the adjusting slide groups 200, the rudder platform groups 300 and the cutting assemblies 400 is several groups, and they are distributed on the truss tooth rod 121 in a one-to-one correspondence manner; each adjusting slide group 200 can move independently, and the overall system supports the distributed adjustment and synchronous control of multiple cutting units.

[0031] Further, to realize the intelligent adjustment function, a control system is further included in the components. The control system includes: Signal acquisition module: It includes a photoelectric sensor installed on the sliding seat 211 for detecting the current position of the adjustment sliding group 200 on the truss tooth rod 121; a rotary encoder installed on the rudder platform group 300 for detecting the rotation angle of the transmission key shaft 320; and a current sensor installed on the cutting assembly 400 for monitoring the operating state of the cutter head.

[0032] Central processing unit: Receives the signals from the above various sensors and judges the status of each module in real time.

[0033] Execution feedback module: According to the instructions of the central processing unit, controls the adjustment drive motor 220, the drive motor 330, and the cutter head drive device to achieve coordinated linkage and intelligent cutting between multiple cutter units. Embodiment 2:

[0034] Based on Embodiment 1, this embodiment further optimizes the cutting pressure adjustment structure.

[0035] A metal thickness recognition component is added to the feeding end of the cutting table 100. This component uses a laser ranging sensor to obtain the thickness information of the metal sheet entering the cutting area in real time. After this thickness signal is transmitted to the central processing unit, the control system will automatically generate a cutting pressure adjustment instruction.

[0036] The adjustment instruction controls the linear push rod device installed on the rudder platform group 300. The output end of the push rod is connected to the support base of the cutter head 410, and its pressing depth can be controlled to adjust the cutting pressure and position of the blade on metal plates of different thicknesses, realizing adaptive pressure matching cutting.

[0037] This structure not only improves the cutting accuracy, avoids the phenomena of "over-cutting" or "incomplete cutting", but also significantly enhances the adaptability of the equipment to metal materials of different thicknesses. It is a high-end metal cutting equipment with feedback perception and intelligent control capabilities.

[0038] Those skilled in the art should understand that the present invention can not only be used for cutting metal sheets, but also can be adapted to different material scenarios such as plastic sheets and composite sheets according to actual needs.

[0039] The working principle and usage process of the present invention: Before use, the operator drives the adjustment sliding group 200 to move horizontally to a specified position on the truss tooth rod 121 through the control system according to the width and tangent position requirements of the target cutting sheet, realizing the reasonable arrangement between each cutting assembly. Subsequently, adjust the drive motor 330 of the rudder platform group 300, and drive the cutter head 410 to set the inclination angle through the transmission key shaft 320 to meet the requirements of straight or oblique cutting.

[0040] The control system uniformly coordinates the operating states of each group of adjusting slider groups 200, rudder platform groups 300 and cutting assemblies 400. The driving motor 330 drives the transmission key shaft 320, and drives the cutter head 410 to rotate at a high speed through the engagement of its lower end with the gear disc seat 420, completing the rotary cutting process of the metal plate. The current sensor during the cutting process is used to monitor the state of the cutter head to ensure smooth cutting.

[0041] After the operation is completed, the operator can quickly remove the cutter head through the quick-release engagement structure provided between the gear disc seat 420 and the cutter head 410, realizing tool replacement or cleaning and maintenance. The overall process has the characteristics of flexible adjustment, accurate angle, variable pressure and stable operation, and is particularly suitable for efficient metal cutting tasks with multiple segments, multiple paths and multiple materials.
