[0049] The present invention will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation mode is only used to further illustrate the present invention and cannot be understood as a limitation on the protection scope of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention according to the above application content.

[0050] Embodiment:

[0051] As Figure 1 、 2 shown, the present invention provides a conveying device for metal rod blanks before quenching, including a roller conveyor 2 for conveying the rod 1. A receiving platform 21 is provided at the end of the roller conveyor 2. An inclined platform 3 is provided on one side of the receiving platform 21 in a smoothly connected manner. A carrying frame 4 is provided on the relatively lower side of the inclined platform 3. A quenching machine 6 is provided at the end of the carrying frame 4. A telescopic rod 41 is provided in the carrying frame 4. A calibration plate 22 is provided on one side of the receiving platform 21. After being conveyed by the roller conveyor 2, the rod 1 can abut against the calibration plate 22.

[0052] The device can convey the rod 1 after the previous process is processed to the receiving platform 21 through the roller conveyor 2, and the position of the rod 1 can be limited by the calibration plate 22 during the conveying process, so that one end of the rod 1 abuts against the calibration plate 22, thereby ensuring that the ends of each group of parallel rods 1 are flush during the subsequent conveying process. The rod 1 can roll into the carrying frame 4 after passing through the inclined platform 3, and then control the telescopic rod 41 to extend to push the rod 1 into the quenching machine 6 in sequence for quenching. A set of roller conveyor 2 or other conveying equipment can be added at the outlet end of the quenching machine 6 to support the quenched rod 1.

[0053] As Figures 1 to 3As shown, in this embodiment, a stop portion that can protrude and retract is provided on the inclined table 3. The stop portion can selectively stop the material rod 1. The stop portion includes a first mounting rod 32 rotatably arranged on the bottom surface of the inclined table 3. A plurality of groups of stop rods 34 are arranged at intervals on the first mounting rod 32. A plurality of groups of through grooves 31 are spaced apart on the inclined table 3. The stop rods 34 can extend out of the through grooves 31. A counterweight 33 is provided at the bottom of the stop rods 34.

[0054] When the first mounting rod 32 is not subject to external force, under the action of the counterweight 33, the stop rods 34 extend out of the through grooves 31 to stop the material rod 1 rolling onto the inclined table 3, preventing it from falling into the positive bearing frame 4 and hitting the telescopic rod 41 in the extended state and causing damage to it. By controlling the rotation of the first mounting rod 32 to drive the rotation of the stop rods 34 so that the stop rods 34 are retracted into the through grooves 31, the stop of the material rod 1 can be released, and thus the material rod 1 can enter the bearing frame 4.

[0055] As Figures 2 to 6 shown, in this embodiment, the stop portion and the telescopic rod 41 are connected by a driving mechanism to drive the stop portion to protrude and retract into the inclined table 3 when the telescopic rod 41 expands and contracts. The driving mechanism includes a sliding frame 35 arranged on the first mounting rod 32. A pushing arm 57 is slidably arranged at the bottom of the bearing frame 4. A pushing shaft 59 is arranged at the end of the pushing arm 57. The pushing shaft 59 is slidably clamped in the sliding frame 35. A transmission component connected to the pushing arm 57 is arranged at the telescopic end of the telescopic rod 41. The transmission component drives the pushing arm 57 to slide when the telescopic end of the telescopic rod 41 expands and contracts.

[0056] The transmission component includes a driving frame 5 slidably arranged at the bottom of the bearing frame 4. Limit frames 43 for limiting the driving frame 5 are arranged on both sides of the bearing frame 4. An inclined groove 51 is opened at one end of the driving frame 5. A driving column 58 is arranged at the end of the pushing arm 57. The driving column 58 is slidably clamped in the inclined groove 51. A limit groove 44 is opened on the limit frame 43. The pushing arm 57 is slidably clamped in the limit groove 44. A push plate 42 is also slidably arranged at the bottom of the bearing frame 4. The push plate 42 is connected to the telescopic end of the telescopic rod 41. A return spring 510 is also arranged at the end of the driving frame 5. The end of the return spring 510 abuts against the bottom baffle of the bearing frame 4.

[0057] After one material pushing operation, the telescopic rod 41 is controlled to retract. When the telescopic end of the telescopic rod 41 retracts, it drives the push plate 42 to move. When the push plate 42 contacts the driving frame 5, it can drive the driving frame 5 to move and compress the return spring 510. During the movement of the driving frame 5, the cooperation between the inclined groove 51 and the driving column 58 can drive the pushing arm 57 to slide. During the sliding process of the pushing arm 57, the cooperation between the pushing shaft 59 and the sliding frame 35 can drive the first mounting rod 32 to rotate, so that the stop rod 34 retracts into the through groove 31, and the material rod 1 on the stop rod 34 rolls into the bearing frame 4 for feeding work. Then, the telescopic rod 41 is controlled to extend again for material pushing. The push plate 42 disengages from the driving frame 5, and under the action of the return spring 510, the driving frame 5 is reset, so that the stop rod 34 extends out of the through groove 31 again to support the subsequent material rod 1. And when the telescopic rod 41 extends to the limit position, the other end of the driving frame 5 is pushed by the push plate 42 to fix the position of the driving frame 5, thereby fixing the position of the stop rod 34, avoiding the inertial movement and retraction of the stop rod 34 caused by the impact when the material rod 1 rolls from the inclined table 3 and contacts the stop rod 34, and improving the safety during feeding.

[0058] As Figure 4 、 5 shown in FIGS. 6, in this embodiment, an abutting plate 54 is provided on the driving frame 5, a threaded rod 53 is provided on the abutting plate 54, a threaded sleeve 52 is provided on the driving frame 5, the threaded rod 53 is screwed into the threaded sleeve 52, and the push plate 42 is arranged between the abutting plate 54 and the driving frame 5. When the device is in use, the position of the abutting plate 54 can also be adjusted according to the length of the material rod 1. By rotating the threaded rod 53 to slide it in the threaded sleeve 52 to drive the abutting plate 54 to move until the distance between the abutting plate 54 and the push plate 42 after the telescopic rod 41 extends is the same as the length of the material rod 1, so as to ensure that the telescopic rod 41 can push the driving frame 5 to slide after shrinking to the length of the material rod 1, effectively avoiding the impact between the material rod 1 and the telescopic rod 41 when the material rod 1 enters the bearing frame 4. A sliding scale 55 is also provided on the driving frame 5. A connecting frame 56 is provided at the end of the scale 55. The connecting frame 56 can abut against the side of the abutting plate 54, and the adjustment distance of the abutting plate 54 can be accurately known according to the reading of the scale 55.

[0059] As Figure 1 、 2As shown, in this embodiment, a feeding part connected to the stopping part through a linkage mechanism is provided on the receiving table 21. The feeding part is driven by the linkage mechanism to supply the material rod 1 to the inclined table 3 when the stopping part protrudes from the inclined table 3. The feeding part includes a second mounting rod 23 rotatably arranged on the receiving table 21 along its axis. A feeding wheel 24 is arranged on the second mounting rod 23. A plurality of groups of feeding grooves 25 are circumferentially spaced on the feeding wheel 24. The material rod 1 can be conveyed from the roller conveyor 2 into one of the feeding grooves 25. The linkage mechanism includes a driving arm 36 arranged on the first mounting rod 32. The upper end of the driving arm 36 is hinged with a locking rod 37. The middle section of the locking rod 37 is connected to the first mounting rod 32 through a tension spring 38. A driving wheel 26 is arranged at the end of the second mounting rod 23. A plurality of groups of ratchet grooves are circumferentially arranged on the driving wheel 26. The end of the locking rod 37 is clamped in the ratchet groove. The number of ratchet grooves is the same as the number of feeding grooves 25.

[0060] When the first mounting rod 32 rotates to drive the stopping rod 34 to retract into the inclined table 3, the end of the locking rod 37 moves outside the driving wheel 26, so as not to control the rotation of the driving wheel 26, and under the action of the tension spring 38, the end of the locking rod 37 is clamped in the ratchet groove. When the first mounting rod 32 rotates in reverse to drive the stopping rod 34 to protrude from the inclined table 3, the driving wheel 26 is driven to rotate through the cooperation of the locking rod 37 and the ratchet groove. During the rotation of the driving wheel 26, the material rod 1 inside it can be pushed out through the feeding groove 25. When the stopping rod 34 completely protrudes, the material rod 1 rolls to one side of the stopping rod 34 and is blocked. At this time, the roller conveyor 2 can continue to convey the material rod 1 into a new group of feeding grooves 25 for subsequent feeding.

[0061] The specific usage method and beneficial effects of the present invention:

[0062] When the device is in use, the material rod 1 is conveyed to the receiving table 21 through the roller conveyor 2. The material rod 1 on the inclined table 3 is stopped by the stopping part, and the telescopic rod 41 is controlled to extend to push the material rod 1 in the bearing frame 4 into the quenching machine 6 for quenching. After the telescopic rod 41 is retracted, the driving mechanism drives the stopping part to retract into the inclined table 3. The material rod 1 on the inclined table 3 rolls into the bearing frame 4. During the process of the telescopic rod 41 extending for pushing the material, the driving mechanism is used to control the stopping part to protrude from the surface of the inclined table 3 again. During the process of the stopping part protruding, the feeding part is driven by the linkage mechanism to supply the material rod 1 to the inclined table 3. The supplied material rod 1 is stopped by the stopping part again, so that the whole device can continuously supply the quenching machine 6, and the feeding process is stable and synchronous, without the need for staff to operate, avoiding errors in the cooperation between multiple devices resulting in the dropping or accumulation of the material rod 1, effectively improving the safety and reliability in the production process, and at the same time, the material rod 1 can be supplied continuously, improving the quenching efficiency of the material rod 1.

[0063] The foregoing has shown and described the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments. Based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of the present invention claimed.
