Description

Technical Field

[0001] This utility model relates to the field of automatic heating of bar stock, specifically to an automatic heating device for the end of round bars of different diameters. Background Technology

[0002] Currently, heating one end of unequal diameter bar stock requires manual intervention. Since the two ends of the unequal diameter bar stock have different diameters, it is impossible to distinguish between the large and small ends during the actual conveying process. Therefore, after the bar stock is fed in an orderly manner by the stepped feeder, it is necessary to manually adjust the bar stock with inconsistent large and small ends. The adjustment process is labor-intensive and the working environment is harsh.

[0003] Secondly, the current method of heating the end of the bar stock is slower than the bar stock feeding speed, so the bar stock feeding area must wait, which inevitably reduces production efficiency. Moreover, the heated bar stock needs to be inspected and screened later, and the waiting time for inspection and screening after feeding will further affect production efficiency.

[0004] To address the aforementioned problems, this utility model designs and manufactures an automatic heating device for the ends of round bars of varying diameters, thereby overcoming the aforementioned deficiencies. Summary of the Invention

[0027] 1. This utility model uses a bar diameter detection sensor to detect the diameter of one end of the bar stock, and then the bar stock is transferred in an orderly manner to the multi-position V-groove of the automatic feeding device by a first robotic arm. During the process, the bars stock with different orientations at the large and small ends are adjusted by the rotary cylinder of the first robotic arm to ensure that the end of the bar stock to be heated faces the induction heating device. Because multiple positioning V-grooves are set, the first robotic arm can continuously grab bars stock from the chain conveyor. During the transfer of bars stock, the bars stock that are grabbed onto the positioning V-grooves first are heated by the induction heating device, and the first robotic arm repeats this cycle. This not only saves the time consumed by induction heating and ensures continuous production, but also automates the entire process and reduces labor intensity.

[0028] 2. The chain conveyor of this utility model ensures the stability of bar material conveying on the conveying chain segment by setting a conveying chain segment and setting baffles on the conveying chain segment. The pushing section uses two upper positioning plates to convey bar material at intervals, which on the one hand ensures stable conveying of bar material, and on the other hand, the elimination of baffles makes it easier for the first robotic arm to grasp the bar material.

[0039] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0040] like Figures 1 to 9 As shown, an automatic heating device for the end of round bars of different diameters includes an automatic turning machine 1. The bars are first fed into the automatic turning machine 1. A stepped feeder 2 is provided on one side of the automatic turning machine 1. The automatic turning machine 1 can transfer the bars inside it to the stepped feeder 2. The stepped feeder 2 can complete the automatic and orderly discharge of the bars. During discharge, all bars are discharged horizontally.

[0041] The stepped feeder 2 is equipped with a chain conveyor 3 at its upper end. The stepped feeder 2 can transfer the transverse bars to the chain conveyor 3. The chain conveyor 3 then transports the bars one by one to the end of the chain conveyor 3. The end of the chain conveyor 3 is equipped with a positioning baffle 36 to restrict the movement of the bars. A bar diameter detection sensor 37 is provided on one side of the end of the chain conveyor 3. The bar diameter detection sensor 37 can detect the diameter of one end of the bar. All bars need to be detected at the positioning baffle 36 and wait for the next process equipment to operate.

[0042] An automatic feeding device 4 is provided on one side of the chain conveyor 3. The automatic feeding device 4 includes multiple positioning V-grooves. Each positioning V-groove has a feeding mechanism at one end and an induction heating device 6 at the other end. After the bar is transferred to the positioning V-groove, the feeding mechanism pushes the bar so that the end of the bar enters the induction heating device 6 for heating.

[0043] The automatic feeding device 4 of this utility model is provided with a first robotic arm 5 above it. The first robotic arm 5 includes a first crossbeam support 51, a first horizontal moving robotic arm 52 is provided on the first crossbeam support 51, a first vertical moving robotic arm 53 slides on the first horizontal moving robotic arm 52, a rotary cylinder 54 is provided at the lower end of the first vertical moving robotic arm 53, and a first bar gripper 55 is provided at the bottom of the rotary cylinder 54.

[0044] This invention uses a bar diameter detection sensor 37 to detect the diameter of one end of the bar, and then the first robotic arm 5 sequentially transfers the bar to the multiple positioning V-grooves of the automatic feeding device 4. During the process, the bars with different diameters are adjusted by the rotary cylinder 54 of the first robotic arm 5 to ensure that the end of the bar to be heated faces the induction heating device 6. Because multiple positioning V-grooves are set, the first robotic arm 5 can continuously grab bars from the chain conveyor 3. During the transfer of bars, the bars that are first grabbed onto the positioning V-grooves are heated by the induction heating device 6, and the first robotic arm 5 cycles in this way. This not only saves the time consumed by induction heating and ensures continuous production, but also automates the entire process and reduces labor intensity.

[0045] A discharge sorting device is provided behind the induction heating device 6. The discharge sorting device includes multiple discharge sorting chutes 9. The number and position of the discharge sorting chutes 9 correspond to the positioning V-shaped grooves. The heated bar stock is pushed onto the discharge sorting chutes 9 by the pushing mechanism. A temperature sensor 7 is provided above the discharge sorting chutes 9. The temperature sensor 7 detects the heating status of the bar stock end and distinguishes between qualified and unqualified products.

[0046] A second robotic arm 8 is provided above the discharge sorting chute 9 and below the temperature sensor 7. The second robotic arm 8 includes a second crossbeam support, a second horizontal moving robotic arm is provided on the second crossbeam support, a second vertical moving robotic arm slides on the second horizontal moving robotic arm, and a second bar gripper is connected to the lower end of the second vertical moving robotic arm.

[0047] It also includes a qualified product discharge chute and a non-qualified product discharge chute. The second robotic arm 8 can transfer the bar stock to the qualified product discharge chute and the non-qualified product discharge chute based on the temperature detected by the temperature sensor 7.

[0048] The automatic feeding device 4 of this utility model has at least three positioning V-shaped grooves. The specific number can be adjusted according to the heating time of each bar by the induction heating device 6. The first robotic arm 5 orderly transfers the bar at the end of the chain conveyor 3 to the positioning V-shaped groove.

[0049] The feeding mechanism includes a linear feed drive and a feed rod disposed at one end of the linear feed drive. The linear feed drive is preferably a cylinder. It should be noted that the cylinder rod of the cylinder should be kept away from entering the induction heating device 6 as much as possible. Moreover, heat insulation material is preferably provided at the connection position between the feed rod and the cylinder rod.

[0050] The chain conveyor 3 of this utility model includes a conveying chain segment 31 and a pushing segment 32. The pushing segment 32 is located at the end of the conveying chain segment 31, and baffles 33 are provided on both sides of the conveying chain segment 31.

[0051] The pushing section 32 specifically includes a support plate, the height of which is the same as the height of the conveying chain section 31. The support plate is provided with two upper positioning plates 35. When the two upper positioning plates 35 are installed side by side on the support plate, the interval between the two upper positioning plates 35 is consistent with the conveying direction of the chain conveyor 3. The bar material on the conveying chain section 31 is continuously conveyed, and the bar material in front is pushed to the interval between the two upper positioning plates 35.

[0052] The chain conveyor 3 of this utility model ensures the stability of bar material conveying on the conveying chain segment 31 by setting a conveying chain segment 31 and setting a baffle 33 on the conveying chain segment 31. The pushing section 32 uses two upper positioning plates 35 to convey bar material at intervals, which on the one hand ensures stable conveying of bar material, and on the other hand, the elimination of the baffle 33 makes it easier for the first robot arm 5 to grab the bar material.

[0053] A pressing frame 34 is preferably provided on the pushing section 32 near the conveyor chain section 31. The pressing frame 34 includes a horizontal bar set above the pushing section 32, a vertical bar at one end of the horizontal bar, and the lower end of the vertical bar is connected to the support plate. This structure can prevent the bar from tilting up through the horizontal bar.

[0054] The lower end of the vertical rod is provided with a vertical long slot, through which the distance between the horizontal rod and the pushing section 32 can be adjusted, which can be used for bars of different diameters; the interval between the two upper positioning plates 35 is adjustable, which can ensure that the bar slides stably in the interval.

[0055] The positioning baffle 36 of this invention is disposed at the end of the gap between two upper positioning plates 35 and is mounted on a support plate. The positioning baffle 36 has a through hole, the position of which corresponds to the conveying position of the chain conveyor 3. A bar material sensor 38 is installed at the through hole position, which can determine whether the bar material has reached the position of the positioning baffle 36. The bar diameter detection sensor 37 is preferably installed on one side of the positioning baffle 36 and faces the bar material at the position of the positioning baffle 36.

[0056] It also includes the corresponding controller, which is connected to the stepped feeder 2, chain conveyor 3, bar material sensor 38, bar diameter detection sensor 37, first robot arm 5, automatic pusher 4, induction heating device 6, temperature sensor 7, and second robot arm 8, thereby ensuring the stable operation of the entire device.
