Description

Technical Field

[0001] The utility model relates to the production of anchor bolts in a fastener system for high-speed railways, in particular to an automatic feeding mechanism for rod-shaped materials. Background Art

[0002] Anchor bolts are the main fastening components in the fastening system. During use, they work together with iron plates, spring bars, T-bolts and other accessories to provide fastening pressure for sleepers and rails.

[0003] Anchor bolt production requirements are as follows: Bars must be processed from Q235, 45 steel, 20MnTiB, or 30CrMnTi steel, with diameters ranging from Φ29.5 to Φ30.5 mm and lengths from 120 to 350 mm. Reduction accuracy requirements are: ±1 mm for the reduction length, and reduction must be completed in one go. Chamfer accuracy requirements are: 4 to 5 by 45 degrees, with no eccentricity permitted. Chamfer width: 4 to 5 by 45 degrees, diameter: 30 to 170 mm, and minimum diameter after necking: 30 to 170 mm.

[0004] The production process for anchor bolts involves cutting, necking, chamfering, local heating, heading, deflashing, stress relief, thread rolling, and surface rust prevention. Currently, necking is typically performed using a 250-ton punch press, followed by chamfering using a semi-automatic or hydraulic chamfering machine. This results in complex and inefficient processes.

[0005] In particular, the loading process of anchor bolts from the silo to the production line currently mostly uses manual loading, which is labor-intensive and has low production efficiency. Utility Model Content

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] Example 1:

[0034] This embodiment discloses an automatic feeding mechanism for rod-shaped materials, which is primarily used for automatically feeding rod-shaped materials from a silo to a production line in anchor bolt production. The following describes the structure and application of the automatic feeding mechanism for rod-shaped materials in conjunction with an automated production line for feeding, necking, and chamfering anchor bolts.

[0035] like Figures 1 to 10 As shown, the automated production line for loading, necking and chamfering of anchor bolts mainly includes a silo 1, an automatic loading mechanism 2, an automatic conveying mechanism, a double-head necking machine and a double-head chamfering machine. The silo 1 and the automatic loading mechanism 2 meet the storage, material sorting and automatic lifting of the bar materials, and place the round bars in an orderly manner on the equipment material channel; the automatic conveying mechanism feeds the round bars one by one into the double-head necking machine, the necking machine completes single-head or double-head necking, and automatically transfers the bar materials to the double-head chamfering machine; the double-head chamfering machine fixes the bar materials on the material rack, completes the single-head or double-head chamfering of the bar materials through the high-speed rotation of the tool, and sends out the bar materials after necking and chamfering.

[0036] The process flow of this embodiment is as follows: manual feeding into the hopper → automatic loading mechanism loads the material and the material is fed into the double-head reducing machine through the automatic conveying mechanism → the double-head reducing machine automatically reduces the diameter → after the reduction is completed, the material is fed into the double-head chamfering machine through the automatic conveying mechanism → the double-head chamfering machine automatically chamfers → after the chamfering is completed, the material is unloaded through the automatic conveying mechanism and fed into the hopper.

[0037] Specifically:

[0038] The automatic feeding mechanism includes a stepped feeding machine 2 and a feeding machine conveyor belt 8 .

[0039] The stepped loader 2 is used to place the bars onto the loader conveyor belt 8 in an orderly manner; when the bars are placed onto the loader conveyor belt, the length direction of the bars is parallel to the conveying direction of the loader conveyor belt.

[0040] The working principle of the stepped loader 2 is as follows: it consists of two slides: one fixed (fixed slide) and one movable (movable slide). A separate motor drives a reducer via a belt drive. The reducer's output shaft drives a connecting rod that pushes the movable slide. When the automatic loader is operating, the bar material is carried from the lower movable slide to the upper fixed slide, which then moves from the upper movable slide to the upper fixed slide, ultimately sliding the material into the feed rail. Typically, the movable slide at the same level is slightly higher than the fixed slide at its highest point, and slightly lower at its lowest point. Workers place product into the hopper, and an alarm is triggered if the hopper is low.

[0041] The stepped loader is a prior art. Its structure has been described in detail in the applicant's prior application CN210498165U, so it will not be described in detail in this embodiment.

[0042] The loader conveyor belt 8 extends in the left and right directions and is used to transport the rods in an orderly manner; the loader conveyor belt 8 has a feed port and a discharge port, the feed port corresponds to the stepped loader 2, and a discharge control device and a pushing device are provided at the discharge port.

[0043] The discharge control device includes a conveyor belt pushing cylinder 3 and a conveyor belt blocking cylinder 4, as well as a discharge port sensor 1 5 and a discharge port sensor 2 7.

[0044] The discharge port's downstream end is the end of the conveying direction, while its upstream end is the beginning. A terminal baffle is located at the end of the discharge port. The conveyor belt stopper cylinder 4 is located in the middle of the discharge port, and an edge baffle is located opposite the conveyor belt pusher cylinder 4. The first bar stock station is formed between the conveyor belt stopper cylinder 4 and the terminal baffle. The pusher cylinder 3 is located at the beginning of the discharge port, and the second bar stock station is formed between the pusher cylinder 3 and the conveyor belt stopper cylinder 4.

[0045] The second discharge port sensor 7 is located at the end of the discharge port, and the first discharge port sensor 5 is located at the beginning of the discharge port.

[0046] The pushing device includes a rod push plate 61 located next to the rod station 1, and a rod push plate 91 located next to the rod station 2. The rod push plate 61 and the rod push plate 62 are both fixed on the pushing bracket, and the pushing bracket is connected to the conveyor belt pushing cylinder 6.

[0047] Equipment channels 22 and 23 are located corresponding to the first and second bar material stations, respectively, and lead to the automatic conveying mechanism. The inlet end of the equipment channel is open, and the outlet end of the equipment channel is closed. The equipment channel is tilted, with the inlet end at the top and the outlet end at the bottom.

[0048] The pushing device can push the bars from the bar-one station and the bar-two station into the equipment material channels 22 and 23 at the same time, and place them in order on the equipment material channels, waiting for the automatic conveying mechanism to pick up the bars.

[0049] The working logic of the automatic loading mechanism is as follows: click the start button, the conveyor belt blocking cylinder 4 extends, the stepped loader 2 moves up and down, and transmits the workpiece upward. Each time it moves up and down, the lower position sensor is connected once, and the stepped loader 2 discharges the material once. After the workpiece is transmitted to the loader conveyor belt 8, the loader conveyor belt 8 transmits the workpiece to the discharge port. After the discharge port sensor 5 senses it, the conveyor belt pushing cylinder 3 is activated to support the second rod (there is an edge baffle on the opposite side of the conveyor belt pushing cylinder 3), the conveyor belt blocking cylinder 4 retracts, releases the first rod, and transmits it to the discharge port second sensor 7, the conveyor belt blocking cylinder 4 extends, the conveyor belt pushing cylinder 3 is released, and the second rod is transmitted to the discharge port sensor 5. There are rods at the rod station 1 and the rod station 2 of the discharge port, then the conveyor belt pushing cylinder pushes the two rods into the equipment material channel. After the full material sensor in the equipment material channel is connected, the loading is stopped, and the loading is continued after the full material sensor in the equipment material channel is disconnected.

[0050] After the feeding system is activated, if the sensor detects that the feed channel is full of bars, the motor stops, and the automatic feeder stops operating. If the feed channel runs out of bars, the sensor sends another signal, causing the motor to start rotating, and the automatic feeder resumes operation. If the bar-out signal persists within a set time (e.g., 2 minutes) after the automatic conveyor mechanism issues it, it indicates an abnormality in the automatic feeder, and the motor stops operating.

[0051] In this embodiment, the double-head necking machine and the double-head chamfering machine are installed on the same equipment frame, with the double-head necking machine and the double-head chamfering machine located at the front and rear of the equipment frame, respectively. The double-head necking machine has two necking sections, one located on the left and right sides of the equipment frame. The double-head chamfering machine has two chamfering sections, one located on the left and right sides of the equipment frame, respectively.

[0052] There are also two sets of automatic conveying mechanisms, located at the front and rear of the equipment frame, namely the first automatic conveying mechanism and the second automatic conveying mechanism. The first automatic conveying mechanism is used for loading and unloading the double-head necking machine; the second automatic conveying mechanism is used for loading and unloading the double-head chamfering machine.

[0053] On the equipment frame, corresponding to the double-head necking machine, a necking support 201 is provided. Two sets of necking support 201 are provided, one for each of the two bar stock. On the equipment frame, corresponding to the chamfering machine, a chamfering support 202 is provided. Two sets of chamfering support 202 are provided, one for each of the two bar stock.

[0054] During operation, the first automatic conveying mechanism moves the rod material from the equipment material channel to the necking material support 201 to complete loading; after loading, the double-head necking machine performs the necking operation; after the necking operation is completed, the first automatic conveying mechanism moves the rod material from the necking material support to the second automatic conveying mechanism to complete unloading.

[0055] The second automatic conveyor mechanism moves the bar stock from the equipment's feed channel to the chamfering support 202 for loading. After loading, the double-head chamfering machine performs the chamfering operation. After chamfering is complete, the second automatic conveyor mechanism removes the bar stock from the chamfering support 202 and drops it into the hopper via the discharge chute 29, completing unloading. The first and second automatic conveyor mechanisms fulfill the material feeding requirements of the chamfering machine and the reducing machine within a confined space.

[0056] The structures of the first automatic conveying mechanism and the second automatic conveying mechanism are basically the same, and the shapes of the loading movable supporting plates of the two are different to adapt to the internal space layout of the equipment rack.

[0057] The specific structure of the first automatic conveying mechanism is as follows:

[0058] The first automatic conveying mechanism includes an upper fixing plate 47 , a middle fixing plate 40 and a lower fixing plate 44 .

[0059] The upper fixed plate 47 is provided with a first and second bar lifting station, each equipped with a bar lifting device. The bar lifting device comprises two parallel movable loading plates 49, which are fixedly connected to the upper fixed plate 47. The loading plates 49 are provided with lifting grooves that mate with the bar. The loading plates 49 are L-shaped, and the lifting grooves are V-shaped.

[0060] In this embodiment, a fixed guide rail 48 extending in the left and right directions is fixed on the upper fixed plate 47, and a slide is fixed at the lower end of the loading movable support plate 49. The slide is installed on the fixed guide rail 48 and locked by screws, which is convenient for adjustment according to different rod lengths.

[0061] The upper fixed plate 47 and the middle fixed plate 40 are connected via an up-and-down moving device, and the up-and-down moving device enables the upper loading movable support plate 49 of the upper fixed plate 47 to move up and down relative to the middle fixed plate 40 .

[0062] In this embodiment, the up and down moving device includes an upper and lower feeding cylinder 41 and two upper and lower guide light shafts 45 arranged parallel to the upper and lower feeding cylinders. The upper ends of the upper and lower guide light shafts 45 are fixedly connected to the upper fixed plate 47, and the lower ends of the upper and lower guide light shafts 45 pass through the middle fixed plate 40 and are slidingly connected to it; the pistons of the upper and lower feeding cylinders 41 are fixedly connected to the upper fixed plate 47, and the cylinder barrels of the upper and lower feeding cylinders 41 are fixedly connected to the middle fixed plate 40.

[0063] The middle fixing plate 40 is connected to the lower fixing plate 44 by a forward and backward moving device, and the forward and backward moving device is used to realize the forward and backward movement of the middle fixing plate 40 relative to the lower fixing plate 44. The lower fixing plate 44 is installed on the equipment frame through a fixing seat 43.

[0064] In this embodiment, the forward and backward movement device includes a forward and backward loading cylinder 42 and a forward and backward guide rail 46 arranged parallel thereto. The forward and backward guide rail 46 is fixed to the lower fixed plate 44, and the middle fixed plate 40 is slidably connected to the forward and backward guide rail 46. The lower fixed plate 44 has movable grooves extending in the forward and backward direction in the portions corresponding to the cylinder barrels of the upper and lower loading cylinders 41 and the upper and lower guide optical axes 45. The cylinder barrels of the upper and lower loading cylinders 41 and the lower half of the upper and lower guide optical axes 45 are located in the movable grooves.

[0065] The cylinder barrel of the front and rear feeding cylinder 42 is fixed on the lower fixed plate 44, and the piston of the front and rear feeding cylinder 42 is connected to the middle fixed plate 40. Two sensors, front and rear in place, are provided in conjunction with the front and rear feeding cylinders 42 to provide automatic process control signals and alarm information judgments.

[0066] When the first automatic conveying mechanism is in operation, the loading movable supporting plate 49 is driven to move by the action of the loading front and rear cylinders 42 and the loading upper and lower cylinders 41 to achieve loading and unloading.

[0067] The specific structure of the second automatic conveying mechanism is as follows:

[0068] The second automatic conveying mechanism includes an upper fixing plate 31 , a middle fixing plate 34 and a lower fixing plate 37 .

[0069] The upper fixed plate 31 is provided with a first and second bar lifting station, each equipped with a bar lifting device. The bar lifting device comprises two parallel movable loading plates 33, which are fixedly connected to the upper fixed plate 31. The loading plates 33 are straight and extend forward and backward. They are equipped with multiple sets of V-shaped lifting grooves arranged along the front-to-back direction to cooperate with the bar.

[0070] In this embodiment, a fixed guide rail 32 extending in the left and right directions is fixed on the upper fixed plate 31, and a slide is fixed at the lower end of the loading movable support plate 33. The slide is installed on the fixed guide rail 32 and locked by screws, which is convenient for adjustment according to different rod lengths.

[0071] The upper fixed plate 31 and the middle fixed plate 34 are connected via an up-and-down moving device, and the up-and-down moving device enables the loading movable support plate 33 on the upper fixed plate 31 to move up and down relative to the middle fixed plate 34 .

[0072] In this embodiment, the up and down moving device includes an upper and lower feeding cylinder 35 and two upper and lower guide light shafts 36 arranged parallel to the upper and lower feeding cylinders. The upper ends of the upper and lower guide light shafts 36 are fixedly connected to the upper fixed plate 47, and the lower ends of the upper and lower guide light shafts 36 pass through the middle fixed plate 34 and are slidingly connected to it; the pistons of the upper and lower feeding cylinders 35 are fixedly connected to the upper fixed plate 31, and the cylinder barrels of the upper and lower feeding cylinders 35 are fixedly connected to the middle fixed plate 34.

[0073] The middle fixing plate 34 is connected to the lower fixing plate 37 by a front-and-rear moving device, and the front-and-rear moving device enables the middle fixing plate 34 to move forward and backward relative to the lower fixing plate 37. The lower fixing plate 37 is mounted on the equipment rack.

[0074] In this embodiment, the forward and backward movement device includes a front and rear loading cylinder 34 and parallel front and rear guide rails 38. The front and rear guide rails 38 are fixed to a lower fixed plate 37, and the middle fixed plate 34 is slidably connected to the front and rear guide rails 38. The lower fixed plate 37 has movable grooves extending in the forward and backward direction in the portions corresponding to the cylinder barrels of the upper and lower loading cylinders 35 and the upper and lower guide optical axes 36. The cylinder barrels of the upper and lower loading cylinders 35 and the lower half of the upper and lower guide optical axes 36 are located in the movable grooves.

[0075] The cylinder barrel of the front and rear feeding cylinders 34 is fixed on the lower fixed plate 37, and the piston of the front and rear feeding cylinders 34 is connected to the cylinder barrel of the upper and lower feeding cylinders 35. Two sensors, front and rear in-position, are provided in conjunction with the front and rear feeding cylinders 34 to provide automatic process control signals and alarm information judgments.

[0076] A fixed loading pallet 51 is also installed on one side of the second automatic conveyor mechanism. Two fixed loading pallets 51 are arranged in groups, each located at the corresponding bar lifting device. These fixed loading pallets 51 are arranged parallel to the movable loading pallet 33 and are fixed to the equipment frame. Multiple groups of lifting slots are arranged on the fixed loading pallets 51 along the front-to-back direction.

[0077] The fixed loading pallet 51 serves as an intermediate buffer area. Since the operating frequencies of the double-head necking machine and the double-head chamfering machine are not completely consistent, the bar material after necking can be placed on the fixed loading pallet 51 first, and then gradually moved forward with the movable loading pallet 33 to realize the step-by-step conveying of the bar workpiece.

[0078] The first automatic conveying mechanism moves the bar material from the equipment material channel to the necking material support 201, and then the double-head necking machine automatically positions and shrinks the bar material. The shrinking must be completed in one go, and eccentricity is not allowed to ensure stable shrinking quality. The double-head necking machine includes but is not limited to the following parts:

[0079] Neck pressing cylinder 14: provides power for workpiece positioning;

[0080] Neck tightening sensor 15: There are two sensors for tightening, one for tightening in place and the other for tightening out, which respectively control the upper limit and lower limit of the tightening action;

[0081] Neck reduction cylinder 16: provides power for neck reduction;

[0082] Neck reduction oil cylinder 2 17: provides power for neck reduction;

[0083] Neck sensor 18: controls the return of the necking cylinder to its original position;

[0084] Neck sensor 2 19: controls the position where the necking cylinder is completed;

[0085] Neck support 201: used to place bar materials;

[0086] The necking presses down the die seat 24 .

[0087] The double-head necking machine boasts excellent stability and a solid, reliable structure, ensuring no deformation or rebound during necking. A displacement sensor is used to ensure accurate positioning of the necking length. The hydraulic ejection mechanism is robust and reliable. The necking die must meet the following requirements or possess the following features: It can be removed and replaced according to product specifications, with ample space for replacement, easy disassembly, installation, and adjustment, and securely fastened. The necking length must be adjustable, easy to adjust, and securely fastened.

[0088] The double-head necking machine uses hydraulic technology to send the part of round steel to be reduced in diameter into a special mold for cold shrinkage and forming. The density of the steel in the reduced part can be greatly increased, thereby improving the compressive strength of the material, while the plasticity and impact toughness are not reduced, making the strength of the threaded part and the rod part consistent, solving the problem of reduced compressive strength and impact toughness due to lathe peeling.

[0089] The necking principle of the double-head necking machine is within the conventional technical capabilities of those skilled in the art and will not be described in detail in this embodiment.

[0090] The double-head chamfering machine is mainly used for automatic chamfering of double ends or single end of bar workpieces. The chamfering can be as large as 4~5*45 degrees without eccentricity. The double-head chamfering machine includes but is not limited to the following parts:

[0091] Servo feed structure 25: The chamfering position is debugged through the touch screen, and the automatic operation can control the chamfering feed position, which includes chamfering retraction position, chamfering speed change position, and chamfering feed position;

[0092] Power head 26: completes chamfering by tool rotation;

[0093] Pressing cylinder 27: the power source for pressing the workpiece;

[0094] Cutter head device 28: The location where the chamfering blade is installed. After the alloy blade is installed and debugged, the cutter head rotates to perform chamfering.

[0095] Unloading chute 29: After the workpiece is chamfered, it slides down the unloading chute to the unloading frame;

[0096] Upper and lower pressing tools 30: press the workpiece tightly to prevent it from loosening during chamfering;

[0097] Neck support 202: used to place bar stock.

[0098] The process steps are: feeding → automatic positioning and clamping → automatic chamfering of either or both ends → chamfering completed and tool retracted → material removal. Material removal and feeding are performed simultaneously, completing the entire process cycle. The double-head chamfering machine ensures consistent chamfer widths on finished workpieces, preventing eccentric chamfering and ensuring consistent chamfer quality.

[0099] The chamfering principle of the double-head chamfering machine is within the conventional technical capabilities of those skilled in the art and will not be described in detail in this embodiment.

[0100] This embodiment also includes a hydraulic station and a hydraulic control system, which provide a power source for the entire device, and a system control cabinet, which is the electrical control part of the entire device.

[0101] This embodiment shortens the workload of multiple workstations to one workstation and realizes automation of the entire processing process, which greatly reduces the process links, reduces the labor intensity, improves the labor safety environment of process operators, and improves production efficiency.

[0102] Example 2:

[0103] In the first embodiment, there is a bar material station 1 and a bar material station 2, and the two stations cooperate with two bar materials to produce simultaneously. In this embodiment, a single station can be operated; or the two stations can be combined into a longer station to adapt to the processing of a single bar material with a longer length.
