Description

Technical Field

[0001] This utility model belongs to the field of CNC sawing technology, specifically relating to a CNC sawing feeding device. Background Technology

[0002] Existing equipment may use simple planar clamps or clamping methods with low friction. For round, square, and other profiles, rolling or sliding can easily occur during feeding, leading to inaccurate positioning and directly affecting the accuracy of the cutting length. Traditional equipment only clamps at a single position, resulting in insufficient clamping force. At the moment of cutting, the downward pressure and torque of the saw blade may cause the rear end of the workpiece to lift or move as a whole, resulting in a non-perpendicular cut surface, chipping, or even damage to the saw blade. At the same time, it relies on manual measurement and feeding. After each cut, the clamps must be loosened, the material manually fed, repositioned, and clamped again. The process is cumbersome, inefficient, and prone to human error. Summary of the Invention

[0003] The present invention aims to solve the technical problems existing in the prior art and provide a feeding device for a CNC sawing machine.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a CNC sawing machine feeding device, a feeding base plate, the feeding base plate including a V-shaped seat and pressure plates on both sides, the front end of the feeding base plate is provided with two sinking grooves, each of the two sinking grooves is provided with a bottom support shaft, the bottom support shafts are rotatably connected to the sinking grooves, each of the two sinking grooves is provided with a gantry frame, a first clamping oil cylinder is installed on the front gantry frame, the protruding end of the first clamping oil cylinder extends into the gantry frame and is connected to a pressure plate at the end, a second clamping oil cylinder is installed on the rear gantry frame, the protruding end of the second clamping oil cylinder extends into the gantry frame and is connected to a lower pressing mounting frame at the end, a power roller is connected in the lower pressing mounting frame, and a drive motor for driving the rotation of the power roller is provided on the side of the lower pressing mounting frame.

[0005] Preferably, a guide shaft is symmetrically provided on the lower pressure mounting brackets on both the front and rear sides of the second clamping cylinder, and the upper ends of the two guide shafts are slidably connected to the gantry frame.

[0006] Preferably, a clearance hole is provided on the gantry corresponding to the drive motor, and the tail of the drive motor is placed in the clearance hole.

[0007] Preferably, a V-groove is provided at the middle position of the V-shaped seat.

[0008] The beneficial effects of this utility model are as follows: The feeding device uses a V-shaped seat and V-shaped groove to naturally position the profile, fundamentally preventing rolling and deviation during feeding and cutting. On this basis, two independent clamping stations are set up. The front station uses a first clamping cylinder and a pressure plate to directly clamp near the cutting point to prevent cutting vibration. The rear station uses a second clamping cylinder and a power roller for clamping and driving. This solves the problems of workpiece lifting and movement caused by inaccurate positioning and single-point clamping in traditional methods, ensuring absolute stability of the cutting process and improving the quality of the cutting surface and tool life.

[0009] By integrating the power roller, drive motor, and clamping cylinder into the rear gantry, a feeding unit integrating "clamping, driving, and guiding" is created, realizing an automated cycle of "clamping-feeding-releasing-clamping". This replaces the inefficient and error-prone manual feeding mode, greatly improving production efficiency and feeding accuracy. Attached Figure Description

[0013] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0014] Example: A feeding device for a CNC sawing machine, such as Figures 1-2 As shown, the feeding base plate includes a V-shaped seat and pressure plates on both sides. The front end of the feeding base plate has two sinking grooves, each containing a bottom support shaft rotatably connected to the sinking groove. Each feeding base plate corresponding to one of the sinking grooves is equipped with a gantry frame. A first clamping cylinder is mounted on the front gantry frame, with its extended end extending into the gantry frame and connected to a pressure plate at its end. A second clamping cylinder is mounted on the rear gantry frame, with its extended end extending into the gantry frame and connected to a downward pressing mounting frame at its end. A power roller is connected to the downward pressing mounting frame, and a drive motor for driving the power roller to rotate is located on the side of the downward pressing mounting frame.

[0015] The second pressing cylinder has a guide shaft symmetrically provided on the pressing mounting brackets on both the front and rear sides, and the upper ends of the two guide shafts are slidably connected to the gantry frame.

[0016] A clearance hole is provided on the gantry corresponding to the drive motor, and the tail of the drive motor is placed in the clearance hole.

[0017] A V-shaped groove is provided in the middle of the V-shaped seat.

[0018] The principle of this utility model: Both the power component and the feeding component are mounted on the frame via the base and the feeding bottom plate;

[0019] Step 1: Loading and initial clamping

[0020] The operator places the long profile into the V-groove of the feeding device. The first and second clamping cylinders operate simultaneously, firmly pressing the profile into the V-groove via the pressure plate and the power roller, respectively.

[0021] Step 2: Fixed-length feeding

[0022] The drive motor below the second clamping cylinder starts, driving the power roller to rotate. Since the profile has been clamped by the power roller, the friction will drive the profile to move forward precisely by the set length (the feeding length is controlled by the number of rotations of the motor). At this time, the first clamping cylinder can be slightly loosened to avoid friction.

[0023] Step 3: Cyclic Preparation

[0024] The first clamping cylinder releases, the second clamping cylinder continues to clamp and drives the power roller to rotate, starting the next feeding cycle, and so on.

[0025] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
