Abstract
Description
Technical Field
[0001] This invention relates to the field of machining technology, and in particular to the field of bar cutting technology. Background Technology
[0002] Many shaft parts can be machined directly from rod stock. Using rod stock for machining reduces the amount of external cutting, greatly improving material utilization and production efficiency. Since the purchased rod stock is of standard length, it needs to be cut into appropriately sized segments before machining.
[0003] Existing patent CN210307956U discloses an automatic equal-segment cutting device for rods, including a processing cavity, a clamping structure, a driving structure, and a cutting structure. The clamping structures are symmetrically arranged on both sides of the upper part of the processing cavity. A mounting plate is welded to the left side of the processing cavity. The cutting structure is horizontally movable via a support roller rotatably mounted on the front of the mounting plate. A driving structure is located on the upper part of the mounting plate. The rod slides down at a uniform speed through the clamping structures. The cutting structure includes a rack, a sliding plate, and a blade welded and fixed to the right end of the sliding plate. The right end of the sliding plate movably penetrates the right wall of the processing cavity. The driving structure drives the cutting structure to swing left and right in the horizontal direction through engagement. However, it can only cut one rod at a time, resulting in low cutting efficiency.
[0004] To improve efficiency, existing patent CN116765901A discloses a rod cutting device, including a device body with a motor mounting plate. The motor mounting plate has a motor and multiple circumferentially arranged sliding grooves. Slider blocks are installed within the sliding grooves, and each slider has a through hole for the rod to pass through. The sliders within the multiple sliding grooves can move synchronously along their respective grooves. During operation, the cutting wheel contacts multiple rods simultaneously, resulting in high force on the cutting wheel and making it prone to damage. Summary of the Invention
[0005] The purpose of this invention is to solve the problems in the prior art and propose a high-efficiency rod cutting device that can cut multiple rods in one operation, while the cutting wheel is not easily damaged.
[0006] To achieve the above objectives, this invention proposes a high-efficiency rod cutting device, comprising a frame, a cutting seat, a cutting machine, and a feeding mechanism. The frame is equipped with a cutting seat, which has vertically arranged cutting grooves open at the top and on both sides. The cutting seat has several material passages arranged horizontally and perpendicular to the cutting grooves. The cutting grooves divide the material passages into an infeed channel and an outlet channel. Both the infeed and outlet channels have clamping blocks inside, which are connected to a first lifting device fixed to the cutting seat. The outlet channel has a vertically arranged baffle connected to a second lifting device fixed to the cutting seat. The frame is equipped with a moving device connected to a cutting machine with a cutting blade. The moving device drives the cutting machine to move horizontally, and the cutting blade's trajectory is parallel to and passes through the cutting grooves. The frame is equipped with several feeding mechanisms corresponding one-to-one with the material passages, located on the infeed side of the cutting seat.
[0007] Preferably, the device also includes a control device for controlling the feeding mechanism, the first lifting device, the second lifting device, the moving device, and the cutting machine. The baffle is equipped with a pressure sensing device on the material blocking side, and the pressure sensing device is connected to the control device via a signal.

[0011] Preferably, the bottom wall of the cutting groove is beveled from the center of the bottom wall to both sides.
[0012] Preferably, the lowest point of the cutting disc's movement trajectory is lower than the lowest point of the feed channel.
[0013] Preferably, the feeding mechanism comprises an upper mounting frame, a lower mounting frame, a first roller, a second roller, and a third lifting device. The lower mounting frame is fixed on the machine frame, and a first drive mechanism and several first rollers are mounted on the lower mounting frame. The first drive mechanism drives all the first rollers to rotate synchronously. The upper mounting frame is located above the lower mounting frame and is connected to a third lifting device mounted on the machine frame.

[0014] Preferably, both the first roller and the second roller have arc-shaped grooves on their surfaces.
[0015] Preferably, the frame is equipped with several nozzles for spraying cutting fluid into the cutting groove.
[0016] The beneficial effects of the present invention are as follows: By setting multiple material passages on the cutting seat, and cooperating with the cutting groove and the cutting machine, the present invention enables the device to cut multiple rods in one cutting process, which effectively improves production efficiency; since the cutting channels are arranged horizontally and the cutting machine also moves horizontally, the cutting blade cuts the rods sequentially, and the cutting blade is not subjected to excessive force and is not easily damaged.

Detailed Implementation
[0020] Example 1: See Figure 1 , Figure 2 and Figure 3 The present invention provides a high-efficiency rod cutting device, comprising a frame 1, a cutting seat 2, a cutting machine 3, and a feeding mechanism.
[0021] The frame 1 is equipped with a cutting seat 2. The cutting seat 2 is provided with a cutting groove 20 that is open at the top and on both sides and is vertically arranged. The cutting seat 2 is provided with a number of material passages that are perpendicular to the cutting grooves 20 and arranged horizontally. The cutting grooves 20 divide the material passages into a feeding channel 21 and a discharging channel 22.
[0022] Both the feeding channel 21 and the discharging channel 22 are equipped with clamping blocks 24. The clamping blocks 24 are connected to the first lifting device 23 fixed on the cutting seat 2. The discharging channel 22 is equipped with a vertically arranged baffle 27, which is connected to the second lifting device 26 fixed on the cutting seat 2.
[0023] The frame 1 is provided with a moving device 30, which is connected to a cutting machine 3 with a cutting blade 31. The moving device 30 drives the cutting machine 3 to move horizontally. The moving trajectory of the cutting blade 31 is parallel to and passes through the cutting groove 20. The lowest point of the moving trajectory of the cutting blade 31 is lower than the lowest point of the feed channel 21.
[0024] To cool the rod and the cutting disc 31, the frame 1 is equipped with several nozzles that spray cutting fluid into the cutting groove 20.
[0025] The frame 1 is equipped with several feeding mechanisms that correspond one-to-one with the material passage. The feeding mechanisms are located on the feeding side of the cutting seat 2 and are used to feed the rod into the material passage.
[0026] It also includes a control device, which is used to control the feeding mechanism, the first lifting device 23, the second lifting device 26, the moving device 30 and the cutting machine 3. The baffle 27 is equipped with a pressure sensing device on the material blocking side, and the pressure sensing device is connected to the control device via a signal.
[0027] Example 2: In order to make the rod material stuck when it enters the feeding channel 21 and the discharging channel 22, the feeding end of the feeding channel 21 and the feeding end of the discharging channel 22 are both provided with a flared mouth 29.
[0028] In order to ensure that the rod is firmly fixed when it is cut and to prevent the rod from rotating during the cutting process, the bottom wall of the feed channel 21 and the bottom wall of the discharge channel 22 are both downwardly concave arc surfaces, and the bottom of the clamping block 24 is provided with a V-shaped clamping port 25.
[0029] In order to allow the cut rod to leave the discharge channel 22 smoothly, the bottom wall of the discharge channel 22 is composed of a first bottom wall and a second bottom wall. The first bottom wall is horizontally set, the second bottom wall is inclined downward, the clamping block 24 is located above the first bottom wall, and the baffle 27 is located above the second bottom wall.
[0030] In order to allow the debris generated during cutting to be discharged smoothly from the cutting groove 20, the bottom wall of the cutting groove 20 is cut at an angle from the center of the bottom wall to both sides.
[0031] Example 3: To ensure that the rod material can smoothly enter the material feeding channel, the feeding mechanism consists of an upper mounting frame 41, a lower mounting frame 42, a first roller 43, a second roller 44, and a third lifting device 45. The lower mounting frame 42 is fixed on the frame 1. A first drive mechanism and several first rollers 43 are mounted on the lower mounting frame 42. The first drive mechanism drives all the first rollers 43 to rotate synchronously. The upper mounting frame 41 is located above the lower mounting frame 42. The upper mounting frame 41 is connected to a third lifting device 45 mounted on the frame 1. A second drive mechanism and several second rollers 44 are mounted on the upper mounting frame 41. The second drive mechanism drives all the second rollers 44 to rotate synchronously. The first rollers 43 and the second rollers 44 rotate synchronously, but in opposite directions.
[0032] The first roller 43 can rotate in both directions under the drive of the first drive mechanism, and the second roller 44 can rotate in both directions under the drive of the second drive mechanism.
[0033] Both the first roller 43 and the second roller 44 have arc-shaped grooves on their surfaces.
[0034] The working process of this invention: In the operation of the high-efficiency rod cutting device of the present invention, the rod material used is straightened rod material. The feeding mechanism puts the rod material into the material passage. When the end of the rod material touches the baffle 27, the pressure sensing device on the baffle 27 transmits the pressure signal to the control device. The feeding mechanism controlled by the control device stops feeding. The first lifting device 23 drives the clamping block 24 to move downward until the rod material is clamped. At this time, the rod material enters the waiting-to-cut state. When all the rod material buckets in the material passage enter the waiting-to-cut state, the control device controls the moving device 30 and the cutting machine 3 to start. The moving device 30 drives the cutting machine 3 to move horizontally. The cutting blade 31 of the cutting machine passes through the cutting groove 20 with the movement of the cutting machine 3, and cuts the rod material in the process of passing through the cutting groove 20.
[0035] The control device can determine whether a rod is completely cut based on the stroke of the moving device 30. When the rod is completely cut, the baffle 27 moves upward under the drive of the second lifting device 26, and then the two clamping blocks 24 move upward under the drive of the first lifting device 23 to release the rod. The first roller 43 and the second roller 44 of the feeding mechanism reverse, and the feeding mechanism moves the rod back a short distance. At this time, the two rod segments produced after the rod is cut will not cause great obstruction to the cutting blade 31, the cutting blade 31 will not be subjected to excessive force, and the cutting blade 31 is not easily damaged.
[0036] After all the rods are cut, the moving device 30 drives the cutting machine 3 to reset. The feeding mechanism moves the rods toward the baffle 27. During the movement, the cut rods are also pushed along. When the center of gravity of the cut rods is above the inclined second bottom wall, the rods will tilt under the action of gravity and slide down the second bottom wall to the outside of the cutting seat 2. Then the baffle 27 is reset under the action of the second lifting device 26. The feeding mechanism continues to move the rods toward the baffle 27. When the end of the rod touches the baffle 27, the pressure sensing device on the baffle 27 transmits the pressure signal to the control device. The feeding mechanism controlled by the control device stops feeding. The first lifting device 23 drives the clamping block 24 to move downward until the rod is clamped. At this time, the rods re-enter the waiting-to-cut state.
[0037] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
