However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0018] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a raw material cutting device for processing oven hoods, including a frame 1. A control system 2 is installed at the front end of the frame 1. A support platform 3 is provided at one end of the frame 1. A first baffle 5 is installed at one end of two protrusions in the frame 1. A second baffle 6 is installed at one end of the support platform 3. A front-back moving mechanism 10 is installed at one end of the first baffle 5. Two sets of fixed plates 11 are provided between the first baffle 5 and the second baffle 6. A guide rod 12 is installed at one end of the movable end of the front-back moving mechanism 10. A movable cylinder 13 is slidably installed on the outer wall of the guide rod 12. A rotating cylinder 131 is rotatably installed on the outer wall of the movable cylinder 13. The two sets of fixed plates 11 are provided. A long screw 14 is rotatably mounted in the middle of the fixed plate 11. A vertical plate 15 is fixedly mounted on the outer wall of the movable cylinder 13. A threaded cylinder 16 is installed through one end of the vertical plate 15. A stepper motor 17 is mounted on one end of one set of fixed plates 11. A cutting blade assembly 18 is mounted on the outer wall of the rotating cylinder 131. A portion of the protrusion in the guide rod 12 is slidably mounted inside the guide groove in the second baffle 6. The lower end of the other set of fixed plates 11 is fixed to the upper end of the protrusion in the guide rod 12. One end of the long screw 14 passes through one end of one set of fixed plates 11 and is fixed to the output end of the stepper motor 17. The stepper motor 17 is connected to the control system 2 via a signal. A telescopic cylinder 19 is movably installed at one end of the vertical plate 15, and a movable head is movably installed at one end of the cutting blade assembly 18. The extended end of the telescopic cylinder 19 is fixed to the upper end of the movable head. A pressing and fixing mechanism 4 is slidably installed on the upper end of the support platform 3. The forward and backward moving mechanism 10 is signal-connected to the control system 2.
[0019] The specific settings and functions of this embodiment are described below. The core load-bearing component of the equipment is the frame 1, which is forged from high-strength aluminum alloy. It has good structural stability and lightweight characteristics, which can effectively reduce vibration interference during equipment operation. The front end of the frame 1 is fixedly installed with a control system 2 by bolts. The control system 2 uses a PLC programmable logic controller as its core and is equipped with a 7-inch touch screen, which makes it easy for operators to set cutting parameters, monitor the equipment operation status, and retrieve historical operation data.
[0020] One end of the frame 1 is integrally formed with a support platform 3. The surface of the support platform 3 is precision ground to provide a high-precision reference surface for the placement and cutting of raw materials. Two protrusions are symmetrically arranged on both sides of the frame 1. One end of the protrusion is fixedly installed with a first baffle 5 by a combination of positioning pins and bolts. The end of the support platform 3 away from the frame 1 is fixedly installed with a second baffle 6 by the same fixing method. The first baffle 5 and the second baffle 6 are arranged parallel to each other to form a longitudinal positioning reference for the raw materials, which can effectively limit the longitudinal displacement of the raw materials during the cutting process.
[0021] Positioning and cutting execution mechanism: The positioning and cutting execution mechanism is the core component for achieving precise cutting. It mainly consists of a forward and backward moving mechanism 10, a guide rod 12, a long screw 14, a threaded cylinder 16, a stepper motor 17, and a cutting blade assembly 18. The specific structure is as follows: Forward and backward moving mechanism 10: This mechanism is fixedly installed on the outer end of the first baffle 5 via a flange. It adopts a transmission form of servo motor and ball screw. The servo motor drives the ball screw nut to move inside the limit frame through the ball screw. The outer end of the ball screw nut will drive the guide rod 12 and the upper fixed plate 11 to move together and reciprocate along the raw material conveying direction, thereby driving the cutting component to achieve precise adjustment of the cutting position. The forward and backward moving mechanism 10 is connected to the control system 2 through an RS485 communication interface and can automatically complete the position adjustment according to the preset parameters.
[0022] Guide rod 12 and movable cylinder 13 assembly: The guide rod 12 is made of chrome-plated alloy steel, and the movable cylinder 13 is slidably sleeved on the outer wall. The inner wall of the movable cylinder 13 is inlaid with a graphite self-lubricating bushing to improve the smoothness of movement and extend the service life of the components. The outer wall of the movable cylinder 13 is rotatably mounted with a rotating cylinder 131 through a deep groove ball bearing. The outer wall of the rotating cylinder 131 is fixedly mounted with a cutting blade assembly 18 through a key connection. The cutting blade assembly 18 adopts a detachable blade holder design, which can quickly replace different types of cutting blades (such as flat blades, toothed blades, etc.) according to cutting needs.
[0023] Long screw 14: A long screw 14 is arranged parallel to each other between the two sets of fixing plates 11. The long screw 14 adopts a trapezoidal thread structure. A vertical plate 15 is welded to the outer wall of the movable cylinder 13. A threaded cylinder 16 is welded to one end of the vertical plate 15. The threaded cylinder 16 and the long screw 14 are threadedly engaged. One end of the long screw 14 passes through the end of one set of fixing plates 11 and is fixedly connected to the output end of the stepper motor 17 through a coupling. The stepper motor 17 is fixedly installed on one set of fixing plates 11 through a motor mount, which can realize the precise lateral movement of the cutting blade assembly 18. The stepper motor 17 is signal-connected to the control system 2, and the rotation angle can be precisely controlled by pulse signals, thereby realizing the precise control of the cutting size.
[0024] Cutting angle adjustment structure: A telescopic cylinder 19 is movably mounted on one end of the vertical plate 15 via a hinge, and a movable head is movably mounted on one end of the cutting blade assembly 18 via a pin. The extended end of the telescopic cylinder 19 is fixedly connected to the upper end of the movable head via a pin. The telescopic cylinder 19 is a small pneumatic telescopic cylinder, and its telescopic stroke can be adjusted by the control system 2. The telescopic cylinder 19 can drive the cutting blade assembly 18 to rotate around the axis of the rotating cylinder 131 through its telescopic movement, so as to realize the continuous adjustment of the cutting angle from 0 to 45° and meet the needs of different cutting bevels. The pressing and fixing mechanism 4 includes a frame, two sets of bolts, and two sets of vertical rods. The frame of the pressing and fixing mechanism 4 slides on the support platform 3. The frame can be fixed to the support platform 3 by bolts. At the same time, through the cooperation of another set of bolts with the pressure plate and the two sets of vertical rods, the other set of bolts moves threaded on the frame. Under the limit of the cooperation between the two sets of vertical rods and the frame, the pressure plate can be driven to move downward, which can fix another part of the raw material.
[0025] Two sets of fixing plates 11 are arranged parallel to each other between the first baffle 5 and the second baffle 6. The fixing plates 11 are made of welded steel plates and are fixedly connected to the first baffle 5 and the second baffle 6 respectively by bolts to form a stable frame structure. The guide rod 12 has a protrusion at one end near the second baffle 6. The protrusion is slidably installed in the guide groove in the second baffle 6. The guide groove is precision milled to further improve the stability of the movement of the guide rod 12. The lower end of the other set of fixing plates 11 is fixedly connected to the upper end of the protrusion in the guide rod 12 by bolts to form a double support for the guide rod 12, which effectively prevents the guide rod 12 from bending and deforming during high-speed movement.
[0026] Example 2: Figure 1 and Figure 4 As shown, cylinders 7 and vertical guide rails 8 are installed on the side walls of the two protrusions in the frame 1. A lower pressure block 9 is set above the support platform 3. Two sets of L-shaped plates 20 are installed on the upper end of the lower pressure block 9. Slide seats 21 are slidably installed on the outer walls of the two sets of vertical guide rails 8. A part of the support platform 3 is set inside the frame 1. The extended ends of the two sets of cylinders 7 are fixed to the upper ends of the two sets of L-shaped plates 20 respectively. One end of each pair of slide seats 21 is fixed to one end of a set of L-shaped plates 20.
[0027] The overall effect achieved by this embodiment is as follows: The pressing mechanism is equipped with a high-precision pressing mechanism to prevent warping and displacement of raw materials during the cutting process. The specific structure is as follows: Cylinders 7 and vertical guide rails 8 are bolted to the side walls of the two protrusions in the frame 1. Cylinders 7 are double-acting cylinders with stable pressure output. Vertical guide rails 8 adopt a linear guide rail structure. A pressing block 9 is installed above the support platform 3. A rubber anti-slip pad is pasted on the lower end of the pressing block 9 to prevent surface scratches when fixing raw materials. Two sets of L-shaped plates 20 are bolted to the upper end of the pressing block 9. Slide seats 21 are slidably installed on the outer walls of both sets of vertical guide rails 8. The slide seats 21 and vertical guide rails 8 are connected by a ball-bearing slider, resulting in low sliding resistance and precise guidance. The extended ends of the two sets of cylinders 7 are fixedly connected to the upper ends of the two sets of L-shaped plates 20 via floating joints. One end of each pair of slide seats 21 is welded to one end of a set of L-shaped plates 20. When the equipment receives the cutting signal, the cylinder 7 first acts, pushing the L-shaped plate 20 to move downward along the vertical guide rail 8, which in turn drives the lower pressure block 9 to press the raw material tightly onto the surface of the support table 3. After the fixing is completed, the cutting mechanism then performs the cutting action to ensure cutting accuracy.
[0028] How to use and how to work with this device: Parameter setting: The operator inputs parameters such as cutting size, cutting angle, and cutting speed through the touch screen of the control system 2, and the system automatically generates the work program; Raw material placement: Place the raw material to be cut on the support platform 3 and perform initial positioning using the first baffle 5 and the second baffle 6; Fixing and clamping: After the equipment is started, the control system 2 first controls the cylinder 7 to move, pushing the lower pressure block 9 to move down along the vertical guide rail 8, pressing the end of the raw material to be cut onto the support table 3. At the same time, the operator operates the lower pressure fixing mechanism 4 to press the other end of the raw material under the oven cover onto the support table. Cutting and positioning: The control system 2 controls the forward and backward moving mechanism 10 and the stepper motor 17 to move the cutting blade assembly 18 along the longitudinal and transverse directions to the preset cutting position, respectively. At the same time, it controls the telescopic cylinder 19 to adjust the cutting angle according to the parameters. Cutting execution: The cutting components move along a preset trajectory to complete the cutting of the raw materials. During the cutting process, the control system 2 monitors the operating status of each component in real time. Reset and material handling: After cutting is completed, the cutting blade assembly 18 is reset, the lower pressure block 9 moves upward to release the raw material, and the operator takes out the cut workpiece to complete one cutting cycle.
[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
