Description

Technical Field

[0001] The present application relates to the field of pneumatic marking machines, and particularly to a steel seal marking machine for steel bars. Background Art

[0002] A steel bar is a material formed by hot rolling or forging a stainless steel ingot. After the production of the steel bar is completed, a marking operation needs to be carried out at one end of the steel bar through a steel seal marking machine. The marking helps in management and traceability during production, sales, and practical use, and also facilitates users to identify different materials and specifications.

[0003] Currently, the Chinese utility model patent with the publication number CN212796366U discloses a steel seal marking machine, which includes a machine frame, a printing head, and a driving device arranged on the machine frame. A positioning device for positioning the workpiece is arranged on the machine frame. The positioning device includes a mounting column, a support seat, and a positioning seat. The mounting column is arranged on the machine frame below the printing head. The support seat is arranged on the mounting column and the workpiece is placed on the support seat. The positioning seat is arranged on the machine frame and is located between the support seat and the printing head and abuts against the vertical side wall of the workpiece to position the workpiece. This utility model has the effect of the same marking position.

[0004] During the marking process of the steel bar, it is still necessary to manually place and adjust the position of the steel bar, resulting in the need for staff to always be beside the equipment during the operation of the steel seal marking machine, which leads to a relatively high working intensity for the staff. Summary of the Invention

[0005] In order to reduce the participation of staff required by the equipment and thus reduce the working intensity of the staff, the present application provides a steel seal marking for steel bars.

[0006] The steel seal marking for steel bars provided by the present application adopts the following technical solutions: A steel seal marking for steel bars includes a machine frame, a storage bin for storing steel bars, a feeding assembly, a transfer assembly, an adjustment assembly, and a marking assembly. The storage bin, the adjustment assembly, and the marking assembly are all arranged on the machine frame. The feeding assembly is used to transport the steel bars in the storage bin to the adjustment assembly. The transfer assembly is used to transport the steel bars on the adjustment assembly to the marking assembly for marking operations. The adjustment assembly includes a receiving table, an adjustment cylinder, and an abutting block. A V-shaped groove for receiving the steel bar is opened on the upper end surface of the receiving table. The length direction of the adjustment cylinder is parallel to the extending direction of the V-shaped groove. The adjustment cylinder and the abutting block are respectively located on both sides of the receiving table. The adjustment cylinder is used to abut one end of the steel bar against the abutting block. The adjusted steel bar can smoothly enter the marking assembly through the transfer assembly.

[0007] By adopting the above technical solution, the steel bars are stored in the storage bin. The feeding component transports the steel bars in the storage bin to the adjusting component. The adjusting component is used to adjust the position of the steel bars. The receiving table is used to receive the steel bars falling from the feeding component. The V-shaped groove is used to define the length direction of the steel bars. The V-shaped groove makes the two ends of the steel bars respectively align with the adjusting cylinder and the abutting block. When the piston rod of the adjusting cylinder extends, one end of the steel bar remains abutted against the abutting block. At this time, the transfer component places the steel bar with the position adjusted on the marking component. The marking component performs a marking operation on the steel bar. By the adjusting component, the steel bars in the same batch are transported to the same position of the marking component. Through the transfer component and the feeding component, the operation of the staff for feeding is reduced. By the adjusting component, the staff's adjustment of the position of the steel bar relative to the marking component is reduced, greatly reducing the staff's participation and thus reducing the working intensity of the staff.

[0008] Optionally, the feeding component includes a feeding frame, a conveyor belt, a stepped lifting plate, a lifting cylinder and a sliding track. The feeding frame is arranged on the storage bin. The conveyor belt is rotatably connected to the feeding frame. The stepped lifting plate is slidably connected in the storage bin along the direction from the inner bottom wall of the storage bin to the conveyor belt. The lifting cylinder is used to drive the stepped lifting plate to move. The sliding track is arranged on the feeding frame. The sliding track is used to guide the steel bars on the conveyor belt to the receiving table.

[0009] By adopting the above technical solution, when the storage bin needs to send the materials to the adjusting component, the piston rod of the lifting cylinder extends, and the steel bars on the stepped lifting plate are lifted until the steel bars are transported to the conveyor belt. The conveyor belt transports the steel bars to the sliding track, and the steel bars move along the sliding track to the receiving table for subsequent adjustment of the position relationship between the adjusting cylinder and the abutting block with respect to the marking component.

[0010] Optionally, the feeding component further includes a blocking plate and a control member. The blocking plate is inserted through and slidably connected to the sliding track. The control member is used to control the blocking plate to block the steel bars on the sliding track.

[0011] By adopting the above technical solution, the lifting cylinder cannot control the number of steel bars transported by the stepped lifting plate to the conveyor belt, and the conveyor belt is only used to transport the steel bars into the sliding track. By driving the blocking plate to slide through the control member, the blocking plate can be used to control the number of steel bars entering the receiving table, improving the stability of the equipment operation.

[0012] Optionally, the control member includes a control cylinder, a first rack, a second rack, and a mating gear. The length direction of the control cylinder is parallel to the direction from the sliding track to the adjustment cylinder. The control cylinder is disposed on the frame. The receiving table is disposed on the piston rod of the control cylinder. The length direction of the first rack is parallel to the telescopic direction of the piston rod of the control cylinder. The first rack is disposed on the piston rod of the control cylinder. The length direction of the second rack is parallel to the sliding direction of the blocking plate. The second rack is disposed on the blocking plate. The mating gear is rotatably connected to the frame. The first rack and the second rack are both engaged with the mating gear.

[0013] By adopting the above technical solution, when there is a steel bar moving towards the receiving table on the sliding track, the piston rod of the control cylinder contracts, and the control cylinder drives the receiving table to approach the sliding track. At this time, the upper end surface of the blocking plate is flush with the sliding track, and the steel bar can smoothly fall into the V-shaped groove. At this time, the piston rod of the control cylinder extends, and the steel bar is driven by the receiving table to move between the adjustment cylinder and the abutting block. At this time, the piston rod of the control cylinder drives the first rack to move, the first rack drives the mating gear to rotate, the mating gear drives the second rack to move, and the second rack drives the blocking plate to expose the sliding track, restricting subsequent steel bars from sliding out of the sliding track. The control member has a simple structure and is easy to operate.

[0014] Optionally, the adjustment assembly is further provided with an avoidance member for reducing the collision with the steel bar during the movement of the receiving table. The avoidance member includes an avoidance plate and a mating block. The avoidance plate is disposed on the receiving table. The mating block is slidably connected to the frame along the length direction of the adjustment cylinder. The abutting block is disposed on the mating block. A sliding groove for guiding the mating block to move towards the adjustment cylinder is formed on the avoidance plate. The mating block is slidably connected in the sliding groove.

[0015] By adopting the above technical solution, there are various specifications of steel bars. When the steel bar enters the receiving table from the sliding track, during the movement of the steel bar towards the abutting block, the abutting block is likely to come into contact with the steel bar, resulting in the steel bar falling out of the V-shaped groove. This problem can be solved by the avoidance member. When the V-shaped groove on the receiving table is used to receive the steel bar, the mating block is located at a position away from the adjustment cylinder. When the piston rod of the control cylinder extends and drives the receiving table to approach the adjustment cylinder, the avoidance plate moves with the table. The sliding groove on the avoidance plate causes the mating block to gradually approach the adjustment cylinder, reducing the collision between the steel bar and the mating block during the movement, thereby reducing the situation of the steel bar falling from the receiving table.

[0016] Optionally, a buffer member is provided on the piston rod of the adjustment cylinder. The buffer member includes a buffer plate and a buffer spring. The buffer plate is slidably connected to the piston rod of the adjustment cylinder along the length of the piston rod of the adjustment cylinder. The buffer spring is used to keep the buffer plate away from the adjustment cylinder.

[0017] By adopting the above technical solution, when the piston rod of the adjustment cylinder extends, the buffer plate will first contact the steel bar, and press one end of the steel bar against the abutting block. Since there are various specifications of steel bars, when the length of the steel bar is relatively long, the buffer plate contacting the steel bar will drive the buffer spring to compress, reducing the direct support force of the abutting block on the steel bar received by the adjustment cylinder and extending the service life of the adjustment cylinder.

[0018] Optionally, the marking assembly includes a marking seat, a marking cylinder, an abutting block, and a first limiting member. The marking seat is arranged on the frame. The length direction of the marking cylinder is parallel to the extending direction of the V-shaped groove of the receiving table. The abutting block is arranged on the marking cylinder. The first limiting member is used to keep the steel bar in a coaxial state with the marking cylinder.

[0019] By adopting the above technical solution, after the adjustment assembly completes the position adjustment of the steel bar, the transfer assembly clamps the steel bar on the adjustment assembly station to the marking assembly. Due to the position adjustment of the steel bar, one end of the steel bar directly fits against the abutting block. Through the first limiting member, the steel bar, the abutting block, and the marking cylinder are located on a straight line. At this time, the piston rod of the marking cylinder extends, and the marking cylinder performs a marking process on one end of the steel bar. Since the end of the steel bar away from the marking keeps fitting against the abutting block, the steel bar will not displace during the marking process, and the quality of the steel bar marking is relatively high.

[0020] Optionally, the first limiting member includes two first limiting blocks, two connecting rods, a first connecting block, and a first limiting cylinder. The two first limiting blocks are respectively located on both sides of the steel bar. The first limiting block is slidably connected to the marking seat along the direction of approaching or departing from the steel bar. The first connecting block is slidably connected to the marking seat along the length direction of the steel bar. The two connecting rods correspond to the two first limiting blocks. One end of the connecting rod is rotatably connected to the first limiting block, and the other end of the connecting rod is rotatably connected to the first connecting block. The first limiting cylinder is used to drive the first connecting block to move.

[0021] By adopting the above technical solution, when the transfer assembly moves the steel bar to the position of the marking assembly, the piston rod of the first limiting cylinder drives the first connecting block to move. The first connecting block drives the two connecting rods to rotate. The two connecting rods drive the two first limiting blocks to approach each other until they abut against the surface of the steel bar, making the steel bar, the marking cylinder, and the abutting block in the same straight line, facilitating the marking process of one end of the steel bar. The structure of the first limiting member is simple and easy to operate.

[0022] Optionally, a chamfering assembly is further provided on the frame. The chamfering assembly is located on the side of the marking assembly away from the adjustment assembly. The chamfering assembly includes a chamfering seat, a second limiting member, two chamfering machine bodies, and two driving cylinders. The chamfering seat is arranged on the frame. The two chamfering machine bodies are distributed along the length direction of the steel bar. The chamfering machine bodies are slidably connected to the chamfering seat along the length direction of the steel bar. The two driving cylinders correspond to the two chamfering machine bodies respectively. The driving cylinders are used to drive the chamfering machine bodies to move. The second limiting member is used to align the two ends of the steel bar with the two chamfering machine bodies respectively.

[0023] By adopting the above technical solution, after the steel bar is marked, the steel bar is moved to the chamfering assembly to chamfer the two ends of the steel bar, thereby reducing the burrs of the steel bar. The second limiting member is used to align the steel bar and the two chamfering machine bodies in a straight line. Then the two driving cylinders drive the two chamfering machine bodies to approach the steel bar, so that the two ends of the steel bar are chamfered. The chamfering assembly reduces the burrs on the surface of the steel bar and improves the quality of the steel bar.

[0024] Optionally, the transfer assembly includes a transfer cylinder, a transfer plate, and three clamping members. The transfer plate is slidably connected to the frame along the direction from the feeding assembly to the marking assembly. The transfer cylinder is used to drive the transfer plate to move. The three clamping members are arranged on the transfer plate along the length direction of the transfer plate. The clamping member includes a vertical cylinder, a double-headed cylinder, and two clamping plates. The vertical cylinder is arranged on the transfer plate. The cylinder body of the double-headed cylinder is arranged on the piston rod of the double-headed cylinder. The two clamping plates are respectively arranged on the two piston rods of the double-headed cylinder.

[0025] By adopting the above technical solution, the three clamping members correspond to the adjustment assembly, the marking assembly, and the chamfering assembly respectively. When the steel bar completes the work at the current station, the double-headed cylinder clamps the steel bar through the clamping plate. The piston rod of the vertical cylinder contracts, so that the steel bar moves above the current station. Then the transfer cylinder drives the rotating plate to move, and the transfer plate drives the clamping member to move above the next station. At this time, the piston rod of the vertical cylinder extends, and then the two clamping plates are loosened, so that the steel bar can be operated by the subsequent station components. The transfer assembly has a simple structure and is easy to operate.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: The operation of the steel bar and the position adjustment of marking are realized through the adjustment assembly and the transfer assembly, reducing the participation of staff and the working intensity of staff; The number of steel bars entering the receiving table is controlled through the control member, and through the linkage with the avoiding member, the situation that the steel bar contacts the abutting block is reduced.

[0027] The chamfering component is used to perform chamfering treatment on the steel bars that have been marked, reduce the burrs on the surface of the steel bars, and improve the quality of the steel bars. Description of the Drawings

[0046] The implementation principle of an embossing machine for steel bars in an embodiment of the present application is as follows: The storage box 2 is used to place steel bars. The lifting cylinder 34 drives the stepped lifting plate 33 to move. The stepped lifting plate 33 moves the steel bar onto the conveyor belt 32. The steel bar moves on the conveyor belt 32 until it is blocked by the limiting plate 39. The pushing cylinder 381 drives the pushing plate 382 to move. The pushing plate 382 pushes the steel bar onto the sliding track 35. The steel bar enters the V-shaped groove 511 of the receiving table 51 through the sliding track 35. The receiving table 51 moves between the adjusting cylinder 52 and the abutting block 53 driven by the control cylinder 371. At this time, the piston rod of the control cylinder 371 extends. The control cylinder 371 drives the first rack 372 to move. The first rack 372 drives the mating gear 374 to rotate. The mating gear 374 drives the second rack 373 to move. The second rack 373 drives the blocking plate 36 to block the subsequent steel bars. The avoidance plate 541 moves along with the receiving table 51. The sliding groove 55 on the avoidance plate 541 makes the mating block 542 approach the adjusting cylinder 52, reducing the contact between the abutting block 53 and the steel bar during the movement of the steel bar.

[0047] When the steel bar on the receiving table 51 is between the adjusting cylinder 52 and the abutting block 53, the piston rod of the adjusting cylinder 52 extends, so that the buffer plate 81 overcomes the elastic force of the buffer spring 82 to abut the steel bar against the abutting block 53, so that the position where the steel bar abuts against the abutting block 53 is kept consistent.

[0048] The steel bar whose position adjustment is completed is transported to the marking component 6 through the transfer component 4. One end of the steel bar after the position adjustment is kept in contact with the opposing block 63. The first limiting member 64 is used to make the opposing block 63, the steel bar, and the marking cylinder 62 in a straight line state, reducing the deviation of the marking position. After marking, the steel bar is moved into the chamfering component 7 through the transfer component 4 again. The second limiting member 72 is used to make the two chamfering machine bodies 73 and the steel bar in a straight line state. The two chamfering machines drive the cylinder 74 to chamfer the steel bar. Finally, the steel bar is moved to the discharge track 44 through the transfer component 4 to complete the discharging.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
