Description

Technical Field

[0001] This utility model belongs to the technical field of feeding mechanism, and in particular relates to an automatic feeding mechanism for forging alloy drill bit blanks. Background Technology

[0002] Forging the blank is a crucial process in the production of alloy drill bits, involving multiple stages such as material selection, heating, forging, cooling, and post-processing. First, a suitable alloy blank is selected based on the drill bit size. Commonly used materials include high-speed steel (such as M2 and M35) or cemented carbide (such as tungsten-cobalt alloys). The blank is uniformly heated to an appropriate temperature in a furnace (1000-1200℃ for high-speed steel and 800-1000℃ for cemented carbide), and then forged using an air hammer, hydraulic press, or forging press.

[0003] The billet is heated by a spiral heater during the feeding process. Since the feeding mechanism cannot directly transfer the heated billet to the forging die, manual or automated robotic operation is required. Manual operation is dangerous and prone to fatigue. Although robotic operation can achieve automation, it is expensive and not suitable for small-batch production manufacturers.

[0004] To address the aforementioned issues, this application proposes an automatic feeding mechanism for forging alloy drill bit blanks. Utility Model Content

[0005] The purpose of this invention is to provide an automatic feeding mechanism for forging alloy drill bit blanks, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an automatic feeding mechanism for forging alloy drill bit blanks, comprising a mounting base and a feeding pipe inclinedly disposed on the mounting base, and further comprising...

[0008] A sensing element, used to sense the blank and hinged to the mounting base, has its front end located directly in front of the material feeding tube in the material feeding direction.

[0009] A rotating plate is hinged on a mounting base, and a rotary cylinder that drives the rotating plate to rotate is provided at the lower end of the mounting base.

[0010] The clamping mechanism is mounted on the rotating plate and can clamp the billet at the bottom of the feed tube.

[0011] Furthermore, the rotating plate includes a clamping plate hinged to the mounting base and a clearance plate fixed to the clamping plate. A support plate is also fixed to the other end of the clearance plate. The bottom of the clearance plate is hinged to the output end of the rotary cylinder on the side near the clearance plate. The base of the rotary cylinder is hinged to the extension frame at the bottom of the mounting base.

[0012] Furthermore, the clamping mechanism includes a stop seat fixed to the upper end of the clamping plate and a clamping plate sliding on the clamping plate. A transition rod arranged along the side of the clearance plate and the support plate is fixed on the clamping plate. A dual-axis cylinder with its output end fixed to the other end of the transition rod is fixed on the outer side of the support plate.

[0013] Furthermore, a guide rod is fixed on the clamping plate, and a guide sleeve that slides with the guide rod is fixed on the clamping plate.

[0014] Furthermore, the stop seat is arc-shaped, and the clamping plate facing the stop seat is V-shaped.

[0015] Furthermore, the upper end of the mounting base is fixed with a bracket to support the feed tube, and the upper end of the feed tube near the rotating plate has an opening.

[0016] Furthermore, the mounting base is provided with a rotating seat that is hinged to the sensing plate. The rear end of the sensing plate on the rotating seat is heavier than the front end. A sensor is also mounted on the mounting base via an adjustment plate. Under normal conditions, the rear end of the sensing plate is in contact with the sensing head of the sensor.

[0017] This utility model has the following beneficial effects:

[0018] This utility model uses an inclined feeding tube and a rotating plate to cooperate. When the plate is tilted, it corresponds to the feeding tube and can catch the blank. Then, it is clamped by a clamping mechanism. The rotating plate is driven to flip by a rotary cylinder, which can make the blank parallel to the forging die. Then, the blank is clamped into the die by a multi-axis gripper, realizing automated feeding, ensuring work efficiency, and the cost is lower than that of a robotic arm.

[0019] This invention mounts a dual-axis cylinder on a support plate, and then uses the connection between the clearance plate and the adapter rod to achieve clearance. After the multi-axis gripper picks up the material, it continues to flip the blank at the bottom of the feeding tube. At this time, the multi-axis gripper sends the blank into the mold. The two work together synchronously to ensure feeding efficiency.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Please see Figure 1 - Figure 4 As shown, this utility model is an automatic feeding mechanism for forging alloy drill bit blanks, including a mounting base 1 and a feeding pipe 2 inclinedly arranged on the mounting base 1. The upper end of the feeding pipe 2 is connected to the discharge end of the bar feeder, which guides the bar blank. It also includes...

[0032] The sensing plate 3 is used to sense the blank and is hinged to the mounting base 1. The front end of the sensing plate 3 is located directly in front of the feeding direction of the feeding pipe 2. The sensing plate 3 is used to determine whether there is blank at the bottom of the feeding pipe 2. Then, after sensing by the sensor 7, it cooperates with the controller to start the dual-axis cylinder 54 and the rotary cylinder 6.

[0033] The rotating plate 4 is hinged to the mounting base 1. The lower end of the mounting base 1 is equipped with a rotary cylinder 6 that drives the rotating plate 4 to rotate. When the rotary cylinder 6 extends, it drives the clamping plate 41 in the rotating plate 4 to be perpendicular to the unloading pipe 2 for contacting the billet. When it retracts, it drives the clamping plate 41 to be parallel to the horizontal plane. At this time, the billet is in a vertical state, which is convenient for the multi-axis gripper to grip. The multi-axis gripper can move along the X, Y, and Z axes to remove the billet from the rotating plate 4 and put it into the forging die.

[0034] The rotating plate 4 includes a clamping plate 41 hinged to the mounting base 1 and a clearance plate 42 fixed to the clamping plate 41. A support plate 43 is also fixed to the other end of the clearance plate 42. The bottom of the clearance plate 42 is hinged to the output end of the rotary cylinder 6 near the clearance plate 42. The base of the rotary cylinder 6 is hinged to the extension frame 14 at the bottom of the mounting base 1. In this embodiment, a clearance space is formed between the clearance plate 42 and the support plate 43 to cooperate with the multi-axis gripper, while not affecting the flipping of the rotating plate 4 and the clamping of the clamping mechanism 5.

[0035] The clamping mechanism 5 is mounted on the rotating plate 4 and can clamp the billet at the bottom of the feeding tube 2. The clamping mechanism 5 includes a baffle seat 51 fixed on the upper end of the clamping plate 41 and a clamping plate 52 sliding on the clamping plate 41. A transition rod 53 is fixed on the clamping plate 52 and arranged along the side of the clearance plate 42 and the support plate 43. A double-axis cylinder 54 with its output end fixed to the other end of the transition rod 53 is fixed on the outside of the support plate 43. In this embodiment, a reinforcing rod to prevent deformation is provided at the included angle of the transition rod 53. When the double-axis cylinder 54 extends, the clamping plate 52 and the baffle seat 51 are released, and when it retracts, the billet is clamped.

[0036] In this embodiment, a guide rod 55 is fixed on the clamping plate 52, and a guide sleeve 56 that slides with the guide rod 55 is fixed on the clamping plate 41. The guide rod 55 and the guide sleeve 56 enhance the structural stability of the clamping plate 52 and the adapter rod 53.

[0037] The material stop 51 is arc-shaped, and the clamping plate 52 is V-shaped opposite the material stop 51. In this embodiment, the arc-shaped material stop 51 and the V-shape on the clamping plate 52 can stably clamp the billet under the push of the dual-axis cylinder 54.

[0038] The mounting base 1 has a bracket 11 fixed at the upper end to support the feeding pipe 2. The upper end of the feeding pipe 2 near the rotating plate 4 has an opening. In this embodiment, the opening at the upper end of the feeding pipe 2 serves to avoid the billet from turning over.

[0039] The mounting base 1 is equipped with a rotating base 12 that is hinged to the sensing plate 3. The rear end of the sensing plate 3 on the rotating base 12 is heavier than the front end. The mounting base 1 is also equipped with a sensor 7 via an adjusting plate 13. Under normal conditions, the rear end of the sensing plate 3 is in contact with the sensing head of the sensor 7. When the billet falls to the bottom of the feeding pipe 2 and is supported on the clamping plate 41, it will press down the front end of the sensing plate 3. At this time, the rear end of the sensing plate 3 is separated from the sensor 7. The sensor 7, together with the controller, first clamps the billet through the clamping mechanism 5, and then flips the billet through the cooperation of the rotating plate 4 and the rotating cylinder 6, which facilitates the clamping of the multi-axis gripper.

[0040] Understandably, by using an inclined feed tube and a rotating plate, the plate catches the billet when it is tilted. After the clamping mechanism clamps the billet, a rotary cylinder drives the plate to flip, making the billet parallel to the forging die. The multi-axis gripper then feeds the billet into the die, achieving automated feeding, improving efficiency and reducing costs compared to a robotic arm. In addition, a dual-axis cylinder is mounted on a support plate and is connected by a clearance plate and an adapter rod to achieve clearance. After the multi-axis gripper picks up the billet, the billet at the bottom of the feed tube continues to flip through the plate and clamping mechanism. At the same time, the multi-axis gripper feeds the billet into the die. The two work synchronously to ensure feeding efficiency.

[0041] A specific application of this embodiment is as follows: The round bar feeder pushes the billet into the spiral heater for heating. When pushing it again, the heated billet slides down from the inside of the feed pipe 2 and is caught by the baffle seat 51 and the clamping plate 41. During the falling process, the front end of the induction plate 3 is pressed down, and the induction plate 3 rotates along the rotating seat 12 and the rear end disengages from the adjusting plate 13. At this time, the sensor 7 transmits a signal to the controller, and the controller sequentially starts the dual-axis cylinder 54 and the rotary cylinder 6. The dual-axis cylinder 54 drives the clamping plate 52 to clamp the billet in the baffle seat 51 through the adapter rod 53. The rotary cylinder 6 retracts and drives the rotating plate 4, the clamping mechanism 5, and the clamped billet to rotate to a vertical state on the mounting base 1. At this time, the multi-axis gripper clamps the billet and moves it into the forging die. During the movement of the billet, the rotating plate 4 and the clamping mechanism 5 reset, clamp the billet again, and flip it. The specific timing diagram is as follows. Figure 5 As shown in the figure, after the blank falls, the sensor 7 is triggered and the clamping mechanism 5 clamps it. In the figure, b is the state where the rotating plate 4 flips and the multi-axis gripper clamps the blank and takes it out from the vertical direction. In the figure, c is the state where the multi-axis gripper moves horizontally and the rotating plate 4 and the clamping mechanism 5 take out the blank again. In the figure, d is the state where the multi-axis gripper moves the blank horizontally to the top of the mold and moves it down to insert the blank into the mold.
