Description

Technical Field

[0001] The present invention relates to the technical field of stock racks, and in particular to a bar stock rack. Background Art

[0002] Long bar materials are widely used in modern society. When processing long bar materials, it is necessary to extract the bar materials from the stock rack stacked with bar materials and then transfer them to the processing machine tool. In the prior art, the feeding action of the bar materials is completed manually. Manual feeding not only has low efficiency, but also has potential safety hazards due to manual fatigue after long-term work, resulting in a decrease in processing efficiency. If a manipulator is selected for material taking and feeding, there will be problems such as high equipment cost, easy malfunction, and unsmooth feeding. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a bar stock rack, which can complete the feeding action of a single bar material, and has the advantages of smooth feeding, simple structure, not easy to malfunction, reducing labor intensity and improving processing efficiency.

[0004] In order to solve the above problems, the present invention adopts the following technical solutions to achieve:

[0005] A bar stock rack of the present invention includes a frame body. A plurality of loading rods for carrying bar materials are arranged side by side on the top of the frame body. A first stopper and a second stopper for blocking the falling of the bar materials are arranged front and back on the loading rod. The first stopper, the second stopper and the top surface of the loading rod enclose a loading and unloading groove. The loading rod is inclined upward from back to front. A flap is arranged between adjacent two loading and unloading grooves. A first guiding surface for lifting the bar body is provided on the top of the flap. The first guiding surface is gradually inclined downward from front to back. The flap is connected to the frame body through a first driving component. The first driving component is used to drive the flap to rotate to lift a single bar material to cross the first stopper and move it into the loading and unloading groove. A buffer component and a roller component are arranged on the frame body. The buffer component is used to buffer the bar material rolling on the first guiding surface. The roller component is used to convey the bar material located in the loading and unloading groove.

[0006] In this solution, the bar stock is stacked on the loading rod. Since the loading rod is inclined upward from back to front and is provided with a first stop block and a second stop block, the bar stock will be blocked in front of the first stop block due to its own weight. When a single bar stock needs to be pumped, the first driving component drives the flap to flip to the vertical state. During the flipping process of the flap, the first guiding surface at the top of the flap contacts the single bar stock and lifts the bar stock so that the bar stock crosses the first stop block and rolls along the first guiding surface. When the bar stock rolls on the first guiding surface, the buffer component can buffer the bar stock to prevent the bar stock from hitting the second stop block due to too fast rolling speed. When the first driving component drives the flap to flip back to the horizontal position, the bar stock is located in the loading and unloading groove. At this time, the roller component can convey the bar stock located in the loading and unloading groove.

[0007] Preferably, the buffer component includes a first driving module and a plurality of buffer modules arranged side by side. The first driving module is arranged on the frame body. The buffer modules correspond to the loading rods one by one. The buffer modules are arranged on one side of the corresponding loading rods. Each buffer module includes a slide rail, a slider and a buffer block. The slide rail is arranged front and back and is connected to one side of the loading rod. One end of the slide rail corresponds to the first stop block, and the other end of the slide rail corresponds to the second stop block. The height of the buffer block is higher than that of the second stop block. The slider can slide on the slide rail. The buffer block is connected to the slider. The first driving module is used to drive the buffer block to drive the slider to slide on the slide rail. When the first driving module drives the buffer block to move backward, the movement of the buffer block drives the slider to slide along the slide rail. When the bar stock rolls along the first guiding surface, the bar stock is always in contact with the buffer block, so that the rolling speed of the bar stock is consistent with the moving speed of the buffer block driven by the first driving module, thereby buffering the bar stock.

[0008] Preferably, the first driving module includes a first rotating shaft, a plurality of first connecting mechanisms arranged side by side and a first driving mechanism. The first rotating shaft is rotatably connected to the frame body. The first connecting mechanisms correspond to the buffer blocks one by one. Each first connecting mechanism includes a swing rod and a connecting rod. The top of the swing rod is hinged to one side of the connecting rod. The bottom of the swing rod is sleeved on the first rotating shaft and is fixedly connected to the first rotating shaft. The other side of the connecting rod is hinged to the corresponding buffer block. The connecting rod is parallel to the slide rail. The first driving mechanism is used to drive the swing rod to swing. When the first driving mechanism drives the swing rod to swing, the bottom of the swing rod drives the first rotating shaft to rotate synchronously, so that the first rotating shaft drives the other swing rods connected to the first rotating shaft to swing. The swing of the swing rod drives the corresponding connecting rod to displace, and the connecting rod drives the corresponding buffer block to move.

[0009] Preferably, a receiving groove is provided at the front end of the first guiding surface. A guiding block is arranged in the receiving groove. The upper part of the guiding block extends out of the receiving groove. The guiding block is rotationally connected to the receiving groove through a second rotating shaft. A torsion spring is sleeved on the second rotating shaft. The torsion spring is used to drive the guiding block to maintain a vertical state. After the guiding block rotates forward by a certain angle, the front side of the guiding block can abut against the inner wall of the front side of the receiving groove. When the flap flips up the rod material, the guiding block contacts the rod material and separates two adjacent rod materials, so that the flap can only lift a single rod material. After the guiding block contacts the rod material, it rotates forward to enable the rod material to move to the first guiding surface through the guiding block. When the front end of the flap is directly below the center line of the rod material, the rod material may roll out of the flap. However, the guiding block can be pressed down by the rod material and rotate forward after the front end of the flap contacts the rod material, preventing the problem that the rod material rolls out of the flap.

[0010] Preferably, a curved surface is provided at the rear end of the top of the guiding block for contacting the rod material.

[0011] Preferably, the first driving assembly includes a connecting cylinder, a connecting shaft, a telescopic cylinder, a plurality of first connecting plates and a second connecting plate. The connecting shaft is fixedly connected to the top of the frame body. The connecting cylinder is sleeved on the connecting shaft and is rotationally connected to the connecting shaft. The bottom of the flap is sleeved on the connecting shaft and can rotate on the connecting shaft. The first connecting plates correspond to the connecting shafts one by one. The top of the first connecting plate is rotationally connected to the corresponding connecting shaft. The first connecting plate is connected to the flap through a connecting member. The bottom of the first connecting plate is hinged to the second connecting plate. The bottom of the telescopic cylinder is hinged to the frame body. The telescopic end of the telescopic cylinder is hinged to the second connecting plate. The slope of the first guiding surface is the same as that of the loading rod. When it is necessary to flip the rod material, the telescopic end of the telescopic cylinder extends out, so that the second connecting plate is pushed to one side. When the second connecting plate moves, it drives the first connecting plate to rotate around the corresponding connecting shaft. The rotation of the first connecting plate drives the corresponding flap to rotate around the corresponding connecting shaft through the connecting member. The same slope of the first guiding surface and the loading rod enables the rod material to be lifted stably, avoiding the shaking of the rod material during lifting.

[0012] Preferably, two flap adjustment grooves are provided on the flap. The flap adjustment grooves are arranged along the front-back direction. An extended connecting column that can slide in the flap adjustment groove is arranged in the flap adjustment groove. An upper limit nut is threadedly connected to the top of the extended connecting column. An upper gasket is arranged between the upper limit nut and the flap. The bottom of the extended connecting column is connected to the connecting member. The connecting cylinder includes a first cylinder body and a second cylinder body. The first cylinder body and the second cylinder body are sleeved on the connecting shaft at intervals. The first cylinder body and the second cylinder body are both fixedly connected to the extended block. The first cylinder body and the second cylinder body can slide along the connecting shaft. A second driving assembly is further arranged on the frame body, and the second driving assembly can adjust the position of the connecting cylinder on the connecting shaft.

[0013] When the size or quantity of the bar stock that needs to be lifted during processing changes, and thus the front and rear positions of the flap need to be adjusted, the upper limit nut at the top of the extension connecting column can be loosened to unlock the flap. At this time, the position of the extension connecting column in the flap adjustment groove can be adjusted. After unlocking, the flap can be adjusted in position on the connecting shaft through the second drive assembly to change the distance that the flap extends. After the adjustment is completed, tighten the upper limit nut to lock the flap. Since the front and rear positions of the flap are adjusted manually, the adjustment position may be inaccurate. When the flap is in the critical position, the bar stock at the front end of the flap will roll forward out of the flap when the flap flips. There are guide blocks and torsion springs at the front end of the flap. After the bar stock contacts the guide blocks at the front end of the flap, it can press down the guide blocks and the torsion springs, causing the guide blocks to rotate forward to lift the bar stock and prevent the bar stock from rolling forward out of the flap.

[0014] Preferably, the connecting member includes a flap connecting plate, the flap connecting plate is connected to the first connecting plate through a third connecting plate, the flap connecting plate is horizontally arranged below the flap and connected to the flap, the flap connecting plate is provided with an extension groove penetrating up and down, the extension groove is arranged in the left-right direction, both of the two extension connecting columns are located in the extension groove and can slide in the extension groove, a lower limit nut is threadedly connected to the bottom of the extension connecting column, a lower gasket is arranged between the lower limit nut and the bottom of the connecting member, the flap and the connecting cylinder are connected through an extension assembly, the extension assembly includes an extension block and an extension sleeve, the extension block is fixedly connected to the connecting cylinder through an extension connecting member, the extension sleeve is sleeved on the extension block and can slide along the extension block, and the extension sleeve is fixedly connected to the flap.

[0015] After changing the front and rear positions of the flap, the positional relationship between the first guide surface for flipping and lifting the bar body on the flap and the loading rod will also change accordingly. The first guide surface may not contact the bottom surfaces of all the bar stocks to be flipped. In order to enable the first guide surface to smoothly flip and lift all the bar stocks to be flipped, the lower limit nut at the bottom of the extension connecting column can be loosened to unlock the flap, and then the flap can be stretched to drive the extension sleeve to slide on the extension block. At this time, the flap drives the extension connecting column to slide in the extension groove, changing the position of the extension connecting column. When the height of the flap is adjusted to the appropriate height, tighten the lower limit nut to lock the flap tightly. At this time, the first guide surface contacts the bottom surfaces of all the bar stocks to be lifted, enabling the bar stocks to be smoothly flipped and lifted.

[0016] Preferably, the second driving assembly includes an adjustment module and a driving module. The adjustment module includes an adjustment plate disposed on the frame. The adjustment plate is slidable back and forth along the frame. A plurality of adjustment protrusions are provided on the top of the adjustment plate. The adjustment protrusions correspond to the flap plates one by one. The adjustment protrusions are located directly below the intervals between the first cylinder and the second cylinder at the corresponding flap plates. The adjustment protrusions extend into the intervals between the corresponding first cylinder and the second cylinder, and the adjustment protrusions are in contact with the corresponding first cylinder and the second cylinder. The driving module is used to change the position of the adjustment plate on the frame. The driving module can change the position of the adjustment plate on the frame. When the position of the adjustment plate changes, the adjustment protrusions on the adjustment plate are synchronously displaced, causing the positions of the corresponding first cylinder and the second cylinder to change, thereby changing the extending distance of the corresponding flap plate.

[0017] Preferably, the driving module includes a first fixing block and a second fixing block. The first fixing block is disposed on the tail of the frame, and the second fixing block is disposed at the bottom of the adjustment plate. A lead screw passing through the first fixing block is threadedly connected to the first fixing block. The rear end of the lead screw is fixedly connected to a turntable. The front end of the lead screw is rotatably connected to the second fixing block. A limiting block is provided between the first fixing block and the turntable. The lead screw passes through the limiting block and is threadedly connected to the limiting block. An adjusting rod is provided on the outer wall of the limiting block. A plurality of limiting plates are arranged side by side on the frame. The limiting plates are provided with limiting adjustment grooves passing through the limiting plates. The limiting adjustment grooves are arranged in the front-rear direction. A limiting post is provided in the limiting adjustment groove. The limiting post is slidable along the limiting adjustment groove. The top of the limiting post is connected to the bottom of the adjustment plate. The bottom of the limiting post is threadedly connected to a limiting nut. A pressing gasket is provided between the limiting nut and the bottom of the limiting plate. By rotating the turntable, the turntable drives the lead screw to rotate. The rotation of the lead screw changes the position of the lead screw in the first fixing block, causing the second fixing block at the front end of the lead screw to drive the adjustment plate to perform synchronous displacement, changing the position of the adjustment plate. The limiting post is connected to the adjustment plate, and the limiting post only slides in the limiting adjustment groove, so that the adjustment plate can only move back and forth, avoiding the adjustment plate moving in other directions to damage the connection between the connecting cylinder and the connecting shaft and avoiding collision between the connecting cylinder and the connecting shaft. Tightening the limiting nut at the bottom of the limiting post can lock the adjustment plate and prevent the adjustment plate from moving.

[0018] The beneficial effects of the present invention are as follows: The flap can lift the rod material over the first stopper and move it into the loading and unloading groove; the guide block can ensure that the rod material at the end of the flap does not roll out of the flap; the buffer assembly can buffer the rod material to prevent the rod material from hitting the second stopper due to too fast rolling; the roller assembly can convey the rod material in the loading and unloading groove to the outside; the first driving module can make the rolling speed of the rod material consistent with the moving speed of the buffer block to buffer the rod material; the second driving assembly can drive the flap to flip; the flap can adjust the corresponding extended distance and the height during flipping for rod materials of different sizes, so as to achieve the smooth flipping and lifting of the rod material and smoothly flip and lift rod materials of different sizes and quantities; the driving module can change the position of the adjusting plate on the frame body, thereby changing the extended distance of the flap; the limit post is connected to the adjusting plate, and the limit post only slides in the limit adjustment groove so that the adjusting plate can only move back and forth, preventing the adjusting plate from moving in other directions to damage the connection between the connecting cylinder and the connecting shaft and avoiding collision between the connecting cylinder and the connecting shaft. The limit nut at the bottom of the limit post can lock the adjusting plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solution of the present invention will be further specifically described below through embodiments in conjunction with the accompanying drawings.

[0031] Embodiment 1: A bar material supporting frame in this embodiment is as Figures 1 to 6 shown. The frame body 1 is provided with five loading rods 2 for supporting bar materials side by side at the top of the frame body 1. A first stop block 21 and a second stop block 22 for blocking the falling of the bar materials are arranged front and back on the loading rod 2. The first stop block 21, the second stop block 22 and the top surface of the loading rod 2 enclose a loading and unloading groove 23. The loading rod 2 is arranged obliquely upward from back to front. A flap 31 is arranged between adjacent two loading and unloading grooves 23. The top of the flap 31 is provided with a first guiding surface 311 for lifting the bar body. The first guiding surface 311 is gradually inclined downward from front to back. The flap 31 is connected to the frame body 1 through a first driving assembly 4. A buffer assembly 9 and a roller assembly 24 are arranged on the frame body 1. The rear end of the top surface of the first stop block 21 is provided with a second guiding surface, and the second guiding surface is gradually inclined downward from front to back.

[0032] The buffer assembly 9 includes a first driving module 91 and five buffer modules 92 arranged side by side. The first driving module 91 is arranged on the frame 1. The buffer modules 92 correspond to the loading rods 2 one by one. The buffer modules 92 are arranged on one side of the corresponding loading rods 2. The buffer module 92 includes a slide rail 921, a slider 922 and a buffer block 923. The slide rail 922 is arranged front and back. The slide rail 922 is connected to one side of the loading rod 2. One end of the slide rail 921 corresponds to the first stop block 21, and the other end of the slide rail 921 corresponds to the second stop block 22. The height of the buffer block 923 is higher than that of the second stop block 22. The slider 922 can slide on the slide rail 921. The buffer block 923 is connected to the slider 922.

[0033] The first driving module 91 includes a first rotating shaft 911, five first connecting mechanisms 93 arranged side by side and a first driving mechanism 94. The first rotating shaft 911 is rotatably connected to the frame 1. The first connecting mechanisms 93 correspond to the buffer blocks 923 one by one. The first connecting mechanism 93 includes a swing rod 931 and a connecting rod 932. The top of the swing rod 931 is hinged to one side of the connecting rod 932. The bottom of the swing rod 931 is sleeved on the first rotating shaft 911 and fixedly connected to the first rotating shaft 911. The other side of the connecting rod 932 is hinged to the corresponding buffer block 923. The connecting rod 932 is parallel to the slide rail 921.

[0034] The first driving assembly 4 includes a connecting cylinder 322, a connecting shaft 321, a telescopic cylinder 41, four first connecting plates 411 and a second connecting plate 412. The connecting shaft 321 is fixedly connected to the top of the frame 1. The connecting cylinder 322 is sleeved on the connecting shaft 321 and rotatably connected to the connecting shaft 321. The bottom of the flap 31 is sleeved on the connecting shaft 321 and can rotate on the connecting shaft 321. The first connecting plates 411 correspond to the connecting shaft 321 one by one. The top of the first connecting plate 411 is rotatably connected to the corresponding connecting shaft 321. The first connecting plate 411 is connected to the flap 31 through a connecting member 413. The bottom of the first connecting plate 411 is hinged to the second connecting plate 412. The bottom of the telescopic cylinder 41 is hinged to the frame 1. The telescopic end of the telescopic cylinder 41 is hinged to the second connecting plate 412. The slope of the first guiding surface 311 is the same as that of the loading rod 2.

[0035] There are two flap adjusting grooves 33 on the flap 31. The flap adjusting grooves 33 are arranged in the front-back direction. An extending connecting column 331 that can slide in the flap adjusting groove 33 is arranged in the flap adjusting groove 33. The top of the extending connecting column 331 is threadedly connected with an upper limit nut. An upper gasket is arranged between the upper limit nut and the flap 31. The connecting cylinder 322 includes a first cylinder body 34 and a second cylinder body 341. The first cylinder body 34 and the second cylinder body 341 are sleeved on the connecting shaft 322 at intervals. The first cylinder body 34 and the second cylinder body 341 are both fixedly connected to the extending block 351. The first cylinder body 34 and the second cylinder body 341 can slide along the connecting shaft 322. A second driving assembly 5 is also arranged on the frame 1.

[0036] The second driving assembly 5 includes an adjustment module 6 and a driving module 7. The adjustment module 6 includes an adjustment plate 61 which is arranged on the frame body 1. The adjustment plate 61 can slide back and forth along the frame body 1. Four adjustment protrusions 611 are arranged on the top of the adjustment plate 61. The adjustment protrusions 611 correspond to the flap 31 one by one. The adjustment protrusions 611 are located directly below the interval between the first cylinder body 34 and the second cylinder body 341 at the corresponding flap 31. The adjustment protrusions 611 extend into the interval between the corresponding first cylinder body 34 and the second cylinder body 341, and the adjustment protrusions 611 are in contact with the corresponding first cylinder body 34 and the second cylinder body 341.

[0037] The driving module 7 includes a first fixing block and a second fixing block 71. The first fixing block is arranged on the tail of the frame body 1, and the second fixing block 71 is arranged on the bottom of the adjustment plate 61. A lead screw 72 passing through the first fixing block is threadedly connected to the first fixing block. The rear end of the lead screw 72 is fixedly connected with a turntable 73. The front end of the lead screw 72 is rotatably connected to the second fixing block 71. A limiting block is arranged between the first fixing block and the turntable 73. The lead screw 72 passes through the limiting block and is threadedly connected to the limiting block. An adjusting rod is arranged on the outer wall of the limiting block. Three limiting plates 8 are arranged side by side on the frame body 1. A limiting adjustment groove 81 passing through the limiting plate 8 is arranged on the limiting plate 8. The limiting adjustment groove 81 is arranged in the front-back direction. A limiting post is arranged in the limiting adjustment groove 81, and the limiting post can slide along the limiting adjustment groove 81. The top of the limiting post is connected to the bottom of the adjustment plate 61. A limiting nut is threadedly connected to the bottom of the limiting post, and a pressing gasket is arranged between the limiting nut and the bottom of the limiting plate 8.

[0038] In this solution, the bar stock is stacked on the loading rod on the stock support. Since the loading rod is inclined upward, the bar stock can be pressed down by its own weight to the front of the first stop block on the loading rod. When a single bar stock needs to be processed, the telescopic end of the telescopic cylinder extends to the left, driving the second connecting plate to move to the left. The leftward movement of the second connecting plate drives the first connecting plate to rotate clockwise around the corresponding connecting shaft. At this time, since the bottom and the telescopic end of the telescopic cylinder are hinged, the second connecting plate can perform a clockwise circular arc motion. The first connecting plate drives the flap to rotate clockwise around the connecting shaft through the third connecting plate, causing the first guiding surface of the flap to start contacting the bottom of the bar stock. The first guiding surface slopes downward gradually from front to back. The height of the second stop block is higher than the height of the lowest point of the first guiding surface, preventing the bar stock from falling outside over the second stop block when the bar stock moves to the loading and unloading groove through the first guiding surface. And when the flap is in the vertical state, the lowest point of the first guiding surface is still higher than the top surface of the first stop block. Therefore, when the flap is in the vertical state, the bar stock moves through the first guiding surface. When the flap continues to rotate to the horizontal state, the bar stock has moved to the loading and unloading groove through the first guiding surface. When the bar stock rolls along the first guiding surface, the telescopic end of the first telescopic cylinder drives the swing rod on the rightmost side of the frame body to swing. The swing of the rightmost swing rod drives the first rotating shaft to rotate. The rotation of the first rotating shaft drives the other swing rods fixedly connected to the first rotating shaft to swing synchronously. When the swing rod swings, it drives the corresponding connecting rod to displace. The displacement of the connecting rod drives the corresponding buffer block to move, causing the slider corresponding to the buffer block to slide on the slide rail. The speed at which the bar stock rolls on the first guiding surface is consistent with the speed at which the first telescopic cylinder drives the buffer block to move, reducing the impact force when the bar stock rolls and buffering the rolling of the bar stock.

[0039] The bar stock has various sizes. To ensure that the flap only lifts a single bar stock each time it flips, the extension length of the flap needs to be controlled. First, loosen the nut on the flap so that the upper plate no longer clings to the flap, unlocking the flap. Then, rotate the turntable to make the lead screw rotate. The lead screw changes its own position through the first fixing block, thereby driving the second fixing block and the adjusting plate to change their positions. When the adjusting plate moves, it is limited by the limit adjusting groove and the limit post in the limit plate and can only move back and forth. During the movement of the adjusting plate, the adjusting protrusion at the top of the adjusting plate extends into the interval between the corresponding first cylinder body and the second cylinder body, driving the corresponding connecting cylinder to move on the corresponding connecting shaft, thereby changing the extended distance of the flap.

[0040] After adjusting the extension distance of the flap, it needs to be locked. At this time, rotate the limit nut at the bottom of the limit post so that the limit nut squeezes the pressing gasket, making the limit post no longer able to slide in the limit adjusting groove, locking the limit post. After the limit post is locked, the adjusting plate can no longer move, and the flap is locked. It is also possible to rotate the adjusting rod so that the limit block clings to the first fixing block, locking the lead screw.

[0041] Example 2: A bar stock carrier in this example has a structure basically the same as that in Example 1. The difference between Example 2 and Example 1 is as follows: As Figure 7 , Figure 8 , Figure 9 and Figure 10 shown, at the front end of the first guiding surface 311 on the flap 31, there is a receiving groove 312. Inside the receiving groove 312, there is a guiding block 313. The upper part of the guiding block 313 extends out of the receiving groove 312. The guiding block 313 is rotationally connected to the receiving groove 312 through a second rotating shaft. A torsion spring is sleeved on the second rotating shaft. The torsion spring is used to drive the guiding block 313 to maintain a vertical state. At the rear end of the top of the guiding block 313, there is a curved surface 314 for contacting the bar stock.

[0042] The connecting member 413 includes a flap connecting plate 42. The flap connecting plate 42 is connected to the first connecting plate 411 through a third connecting plate 421. The flap connecting plate 42 is horizontally arranged below the flap 31 and is connected to the flap 31. The flap connecting plate 42 is provided with an extending groove 422 that runs through up and down. The extending groove 422 is arranged in the left - right direction. Inside the extending groove 422, there are two extending connecting columns 331 that can slide in the extending groove 422. The tops of the two extending connecting columns 331 are connected to the flap 31. The bottom of the extending connecting column 331 is threadedly connected with a lower limit nut. A lower gasket is arranged between the lower limit nut and the bottom of the connecting member 413. The flap 31 and the connecting cylinder 322 are connected through an extending assembly 35. The extending assembly 35 includes an extending block 351 and an extending sleeve 352. The extending block 351 is fixedly connected to the connecting cylinder 322 through an extending connecting piece 353. The extending sleeve 352 is sleeved on the extending block 351 and can slide along the extending block 351. The extending sleeve 352 is fixedly connected to the flap 31. A locking mechanism is also arranged on the extending block 351 to lock the extending block and the extending sleeve after the flap is stretched.

[0043] After changing the front - rear position of the flap, the positional relationship between the first guiding surface on the flap for lifting the bar body and the loading rod will also change accordingly. Although the slopes of the first guiding surface and the loading rod are the same, due to the front - rear change in the position of the flap, the first guiding surface cannot contact the bottom surfaces of all the bar stocks to be flipped and lifted. To ensure the smooth flipping and lifting of the bar stocks, the flap can be unlocked by loosening the lower limit nut at the bottom of the extending connecting column, and then the flap is stretched to drive the extending sleeve to slide on the extending block. At this time, the flap drives the extending connecting column to slide in the extending groove, changing the position of the extending connecting column. When the height of the flap is adjusted to the appropriate height, the lower limit nut is tightened to lock the flap, so that the first guiding surface always contacts the bottom surfaces of all the bar stocks to be flipped and lifted, enabling the bar stocks to be flipped and lifted smoothly.

[0044] When the flap is in the critical position, the bar stock located at the front end of the flap will roll forward out of the flap when the flap flips. There are guide blocks and torsion springs provided at the front end of the flap. After the bar stock contacts the guide blocks at the front end of the flap, it can press down the guide blocks and the torsion springs, causing the guide blocks to rotate forward to lift the bar stock and prevent the bar stock from rolling forward out of the flap.
