Description

Technical Field

[0001] This application relates to the field of bar cutting machines, and more particularly to a feeding device for a bar cutting machine. Background Technology

[0002] Stainless steel bars are made from stainless steel ingots through hot rolling or forging. During the production process, longer bars are first cut into pieces using a cutting machine, and then the bars undergo further processing.

[0003] In related technologies, please refer to Chinese utility model patent with authorization announcement number CN222199062U, which discloses a high-safety bar cutting machine, including a cutting feeder, a cutting motor, a cutting blade, a mounting component, and a limiting component. The cutting motor is mounted on the cutting feeder, and the limiting component includes a limiting disc, a limiting block, and a retaining component. The limiting disc is mounted on the output shaft of the cutting motor, and the limiting block is slidably connected to the cutting feeder along the direction close to or away from the limiting disc. The retaining component is used to keep the limiting block in contact with the limiting disc. The cutting blade is mounted on the output shaft of the cutting motor through the mounting component, which improves the safety of changing blades in the bar cutting machine.

[0004] When the bar stock is cut, it needs to be placed and fed manually. After cutting, the position of the bar stock needs to be adjusted manually and cut again. The feeding operation is inconvenient and the feeding efficiency is low, which is not conducive to continuous operation. Utility Model Content

[0005] To address the inconvenience and low efficiency of manual bar feeding, this application provides a feeding device for a bar cutting machine.

[0006] The feeding device for a bar cutting machine provided in this application adopts the following technical solution:

[0007] A feeding device for a bar cutting machine includes a feeding rack disposed on one side of the cutting kerf of the bar cutting machine. The feeding rack is equipped with rollers for transporting bars toward the side of the bar cutting machine. Several rollers are arranged along the bar transport direction. A feeding assembly is disposed on the feeding rack, comprising a feeding plate slidably mounted on the feeding rack and a clamping member disposed on the feeding plate. The clamping member is used to clamp the bar. A driving member is disposed on the feeding rack for driving the feeding plate to reciprocate along the bar transport direction. A loading rack for storing bars is disposed on one side of the feeding rack, and a feeding mechanism for transporting bars from the loading rack to the rollers is disposed on the loading rack.

[0008] By adopting the above technical solution, the feeding mechanism transports the bar stock from the loading rack to the rollers on the feeding rack. The driving component drives the feeding plate to move to the clamping component to clamp the bar stock. At this time, the driving component drives the feeding plate to move towards the side of the bar cutting machine. The cutting machine then cuts the bar stock. After the cutting is completed, the clamping component releases the bar stock. The driving component drives the feeding plate to move to the clamping component to clamp the subsequent bar stock segments. Then, the driving component drives the bar stock to move for subsequent cutting operations. The continuous feeding operation of the bar stock is convenient.

[0009] Optionally, the driving component includes a motor and a lead screw. The feeding frame is provided with guide rods distributed along the bar transport direction. The feed plate is slidably connected to the guide rods. The motor is mounted on the feeding frame. The lead screw is rotatably mounted on the feeding frame and distributed parallel to the guide rods. The lead screw is connected to the output shaft of the motor. The feeding frame and the lead screw are threadedly connected.

[0010] By adopting the above technical solution, the motor drives the lead screw to rotate, the lead screw drives the feed plate to move along the guide rod, and the guide rod guides the movement of the feed plate. The movement of the feed plate is conveniently controlled by the motor and lead screw, and the feed amount of the bar is easy to control.

[0011] Optionally, the clamping component includes a hydraulic cylinder and a clamping block. The hydraulic cylinder is disposed on the feed plate, and the clamping block is disposed at one end of the piston rod of the hydraulic cylinder and slidably connected to the feed plate. The driving direction of the hydraulic cylinder is perpendicular to the transport direction of the bar. The feed plate is provided with a top plate on the side opposite to the clamping block. The opposite sides of the outer circumference of the bar are respectively attached to one side of the clamping block and one side of the top plate. The feeding rack is provided with a clamping component for fixing one end of the bar.

[0012] By adopting the above technical solution, the hydraulic cylinder drives the clamping block to slide to the clamping block and the top plate to clamp the outer circumferential wall of the bar. At this time, the feed plate moves, driving the bar to move. When cutting, the clamping part limits one end of the bar.

[0013] Optionally, the feeding mechanism includes a feeding cylinder and a rotating plate. The loading rack is inclined, with its lower side facing the feeding rack. A rotating shaft distributed along the bar transport direction is rotatably mounted on the loading rack. The rotating plate is connected to the rotating shaft. The feeding cylinder is mounted on the feeding rack, with one end rotatably connected to the loading rack. A push rod is rotatably connected to one end of the piston rod of the feeding cylinder, and the push rod is connected to the rotating shaft.

[0014] By adopting the above technical solution, the feeding cylinder drives the push rod to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft drives the rotating plate to rotate, and the rotating plate pushes the bar on the feeding rack to move and flip to the feeding rack. At this time, one end of the rotating plate pushes the bar to abut, and the subsequently placed bar moves along the inclined feeding rack to prepare for the next feeding.

[0015] Optionally, the feeding rack is provided with a placement rack, a limiting plate is provided on one side of the placement rack that abuts against one side of the feeding rack, a baffle is provided on the side of the placement rack away from the feeding rack, and a limiting wheel is provided on the placement rack, with the bar placed between the baffle and the limiting wheel.

[0016] By adopting the above technical solution, when the transfer plate pushes the bar to move, the bar flips along the limiting plate on one side onto the placement frame and is located between the baffle and the limiting wheel, thus limiting the position of the bar.

[0017] Optionally, the limiting plate and the baffle are connected by a connecting plate. A slider is provided on one side of the connecting plate. The slider slides in the direction toward and away from the feeding rack. The placement rack is provided with a groove for the slider to slide in. A rotating screw is rotatably installed on the placement rack at the groove. The slider and the rotating screw are threadedly connected.

[0018] By adopting the above technical solution, the rotating screw drives the slider to slide, the slider drives the connecting plate to move, the connecting plate drives the limit plates and baffles on both sides to move, and the position of the baffles can be adjusted, which is suitable for limiting different bars.

[0019] Optionally, the feeding rack is provided with a position sensor for detecting the bar on the side facing the bar cutting machine.

[0020] By adopting the above technical solution, the position sensor detects the position of the bar. When the bar is finished being fed on the feeding rack, the position sensor can no longer detect the bar. At this time, the feeding cylinder on one side of the feeding rack drives the bar to be released, which facilitates continuous operation of bar cutting.

[0021] Optionally, the clamping component includes a clamping cylinder and an abutting roller. The abutting roller is rotatably mounted on the feeding frame. The outer circumferential wall of the abutting roller abuts against the outer circumferential wall of the bar. The clamping cylinder is located on the side of the bar away from the abutting roller. A clamping block is provided at one end of the piston rod of the clamping cylinder. The clamping block moves toward or away from the abutting roller.

[0022] By adopting the above technical solution, when cutting, the clamping cylinder drives the clamping block to move to one side of the bar, and the clamping block and the abutment roller clamp the bar, thereby improving the stability of the bar during cutting.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] The feeding mechanism transports the bar stock from the loading rack to the rollers on the feeding rack. The drive unit moves the feed plate to the clamping unit to clamp the bar stock. At this time, the drive unit drives the feed plate to move towards the side of the bar cutting machine. The cutting machine then cuts the bar stock. After the cutting is completed, the clamping unit releases the bar stock. The drive unit moves the feed plate to the clamping unit to clamp the subsequent bar stock segments. Then, the drive unit moves the bar stock to perform subsequent cutting operations. The continuous feeding operation of the bar stock is convenient.

[0025] Adjusting the rotating screw drives the slider to slide, the slider moves the connecting plate, and the connecting plate moves the limit plates and baffles on both sides. Adjusting the position of the baffles is suitable for limiting different bars.

[0026] The clamping cylinder drives the clamping block to move to one side of the bar, and the clamping block and the abutment roller clamp the bar, improving the stability of the bar during cutting. Attached Figure Description

The feeding plate 22 is slidably mounted on the side of the feeding rack 2 facing the bar cutting machine 1 along the length direction of the feeding rack 2. The clamping member 23 includes a hydraulic cylinder 231 and a clamping block 232. The hydraulic cylinder 231 is mounted on the feeding plate 22, and the clamping block 232 is mounted at one end of the piston rod of the hydraulic cylinder 231 and is slidably connected to the feeding plate 22.

A top plate 233 is provided on the side opposite to the clamping block 232. Limiting blocks 2331 are provided on the opposite side of the top plate 233 and the clamping block 232. The limiting blocks 2331 on both sides are relatively distributed. The opposite sides of the outer circumference wall of the bar are respectively attached to the limiting blocks 2331 of the clamping block 232 and the top plate 233. The hydraulic cylinder 231 drives the clamping block 232 to slide to the clamping block 232 and the top plate 233 to clamp the outer circumference wall of the bar. At this time, the feed plate 22 moves, driving the bar to move.

[0037] Reference Figure 1 and Figure 2The feeding frame 2 is equipped with a driving component 24, which includes a motor 241 and a lead screw 242. Guide rods 25 are distributed along the length of the feeding frame 2. The feed plate 22 is slidably connected to the guide rods 25. The motor 241 is mounted on the feeding frame 2, and the lead screw 242 is rotatably mounted on the feeding frame 2 and distributed parallel to the guide rods 25.

The feeding rack 3 is distributed along the length of the feeding rack 2, and the lower side of the feeding rack 3 is located on one side of the feeding rack 2. A feeding mechanism 4 is provided on the feeding rack 3. The feeding mechanism 4 includes a feeding cylinder 41 and a rotating plate 42. The feeding rack 3 is inclined, and the lower side of the feeding rack 3 is distributed towards the feeding rack 2. A rotating shaft 31 is rotatably installed on the feeding rack 3 on the side facing the feeding rack 2. The rotating shaft 31 is distributed along the length of the feeding rack 3. The rotating plate 42 is connected to the rotating shaft 31 and is distributed perpendicular to the rotating shaft 31. One side of the rotating plate 42 abuts against one side of the bar. The feeding cylinder 41 is arranged on the feeding rack 2. The bottom of the feeding cylinder 41 is rotatably connected to the feeding rack 3. One end of the piston rod of the feeding cylinder 41 is arranged upward and rotatably connected to a push rod 43. The end of the push rod 43 away from the feeding cylinder 41 is connected to the rotating shaft 31. The feeding cylinder 41 drives the push rod 43 to rotate, which in turn drives the rotating shaft 31 to rotate. The rotating shaft 31 drives the rotating plate 42 to rotate. The rotating plate 42 pushes the bar on the feeding rack 3 to move and flip to the feeding rack 2. At this time, one end of the rotating plate 42 pushes the bar to abut. The subsequently placed bar moves along the inclined feeding rack 3, ready for the next feeding.

[0039] Reference Figure 1 and Figure 4The feeding rack 2 is equipped with a support member 5, which includes a support screw 51 and a threaded sleeve 52. The threaded sleeve 52 is fixedly installed on the feeding rack 2, and the support screw 51 is threaded onto the threaded sleeve 52 of the feeding rack 2.

Rotating the handwheel 53 adjusts the length of the support screw 51, thereby adjusting the support for different numbers of bars. A position sensor 26 for detecting the bar is provided on the side of the feeding rack 2 facing the bar cutting machine 1. The position sensor 26 detects the position of the bar. When the bar is finished being fed on the feeding rack 2, the position sensor 26 can no longer detect the bar. At this time, the feeding cylinder 41 on one side of the feeding rack 2 drives the bar to be released, which facilitates continuous bar cutting operations.

[0040] Reference Figure 4 The feeding frame 2 is equipped with a clamping component 6, which includes a clamping cylinder 61 and an abutment roller 62. The abutment roller 62 is rotatably mounted on the feeding frame 2, and its outer circumferential wall abuts against the outer circumferential wall of the bar. The clamping cylinder 61 is located on the side of the bar away from the abutment roller 62, and a clamping block 63 is provided at one end of the piston rod of the clamping cylinder 61. The clamping block 63 moves toward or away from the abutment roller 62. When cutting, the clamping cylinder 61 drives the clamping block 63 to move to one side of the bar, and the clamping block 63 and the abutment roller 62 clamp the bar, improving the stability of the bar during cutting.

[0041] Reference Figure 3 and Figure 5 The feeding rack 2 is equipped with a placement rack 7. A limit plate 71 is vertically mounted on the side of the placement rack 7 facing the feeding rack 3. Two limit plates 71 are provided on either side of the placement rack 7, staggered. The height of the limit plate 71 facing the feeding rack 3 is greater than the height of the other limit plate 71. The limit plates 71 have chamfered edges with the same angle. A baffle 72 is provided on the side of the placement rack 7 away from the feeding rack 3. A limit wheel 73 is also provided on the placement rack 7. The bar is placed between the baffle 72 and the limit wheel 73. When the transfer plate 42 pushes the bar to move, the bar sequentially flips along the two limit plates 71 onto the placement rack 7, positioned between the baffle 72 and the limit wheel 73.

[0042] Reference Figure 3 and Figure 5One side limiting plate 71 and baffle 72 are connected by a connecting plate 74. A slider 75 is provided on one side of the connecting plate 74. The slider 75 slides in the direction towards and away from the loading rack 3. The placement rack 7 is provided with a groove 76 for the slider 75 to slide. A rotating screw 77 is rotatably installed on the placement rack 7 at the groove 76. The slider 75 is threadedly connected to the rotating screw 77. Adjusting the rotating screw 77 drives the slider 75 to slide. The slider 75 drives the connecting plate 74 to move. The connecting plate 74 drives the limiting plates 71 and baffle 72 on both sides to move. Adjusting the position of the baffle 72 is suitable for limiting different bars.

[0043] The implementation principle of the feeding device of the bar cutting machine 1 in this embodiment is as follows: the feeding cylinder 41 drives the push rod 43 to rotate, which in turn drives the rotating shaft 31 to rotate. The rotating shaft 31 drives the rotating plate 42 to rotate. The rotating plate 42 pushes the bar on the feeding rack 3 to move and flip to the roller 21 of the feeding rack 2. The motor 241 drives the lead screw 242 to rotate, which in turn drives the feeding plate 22 to move. The hydraulic cylinder 231 drives the clamping block 232 to clamp the bar. At this time, the feeding plate 22 is driven to move towards the side of the bar cutting machine 1. The moving and clamping cylinder 61 drives the clamping block 63 to clamp the bar. The cutting machine cuts the bar. After cutting, the clamping block 232 releases the bar. The lead screw 242 rotates to drive the feed plate 22 to move to the clamping block 232 to clamp the subsequent bar segments. Then, the bar is moved to carry out the subsequent cutting operation. When the bar is finished being fed on the feeding rack 2, the position sensor 26 cannot detect the bar. At this time, the feeding cylinder 41 on one side of the feeding rack 2 drives the bar to be released to continue the next cutting operation.
