[0023] Figure 1 A schematic diagram of an automatic bolt collection production line according to an embodiment of the present invention is shown. Figure 1The automatic bolt collection production line is located in the production workshop, and includes: the first to fourth conveying devices, the first to third reversing devices, and the first group of processing equipment, the thread rolling machine 7, the second group of processing equipment, and the transfer area 8 arranged in sequence along the first direction. Among them, the first group of processing equipment includes a cold heading machine 1, a vibration device 2, and an oil removal device 3 arranged in sequence along a second direction perpendicular to the first direction. The cold heading machine 1 is used to cold-head the raw material, the vibration device 2 is used to preliminarily remove the oil stains on the surface of the workpiece after cold-heading by the cold heading machine 1, and the oil removal device 3 is used to clean the workpiece after the surface oil stains are preliminarily removed after the vibration device 2 is processed. The workpiece processed by the cold heading machine 1, the vibration device 2, and the oil removal device 3 is temporarily stored in the transfer area 8 as the first bolt semi-finished product. The thread rolling machine 7 is used to perform thread rolling on the workpiece after cold heading, and the workpiece processed by the thread rolling machine 7 is also temporarily stored in the transfer area 8 as the second bolt semi-finished product. The second group of processing equipment includes a hot thread rolling device 4, a quenching heating furnace 5, and a tempering heating furnace 6 arranged in sequence along a second direction perpendicular to the first direction.

The quenching heating furnace 5 is used to heat the first semi-finished bolt after thread forming to the required temperature for quenching. The quenching heating furnace 5 is also used to heat the second semi-finished bolt taken out from the transfer area 8 to the required temperature for quenching. The tempering heating furnace 6 is used to heat the workpiece processed by the quenching heating furnace 5 to the required temperature for tempering. The first to fourth conveying devices are respectively arranged between the cold heading machine 1 and the vibration device 2, between the hot thread rolling device 4 and the quenching heating furnace 5, between the quenching heating furnace 5 and the tempering heating furnace 6, and between the cold heading machine 1 and the thread rolling machine 7.

[0024] This embodiment only requires that the first direction and the second direction are perpendicular to each other, and does not make any specific limitations on the first direction and the second direction. For example, the first direction is the width direction of the production workshop, and the second direction is the length direction of the production workshop, or the first direction is the length direction of the production workshop, and the second direction is the width direction of the production workshop.

[0025] The bolt automatic collection production line of this embodiment can perform at least two production processes on the bolts. Specifically, the first production process is a hot rolling thread forming process (see Figure 1In the solid line path in the figure), the workpiece is first processed by the cold heading machine 1, the vibration equipment 2, and the oil removal equipment 3 in sequence. The workpiece processed by the oil removal equipment 3 is temporarily stored in the transfer area 8 as the first semi-finished bolt. After the first semi-finished bolt is taken out from the transfer area 8, it is processed by the hot thread rolling equipment 4, the quenching heating furnace 5, and the tempering heating furnace 6 in sequence. The workpiece obtained after processing in the tempering heating furnace 6 is temporarily stored in the transfer area 8 again. At this point, the hot thread rolling thread forming process of the bolt is completed.

[0026] The second production process is the thread rolling screw thread forming process (see Figure 1 In the dotted line path in the figure, the workpiece is first processed by the cold heading machine 1 and the thread rolling machine 7 in sequence, and the workpiece processed by the thread rolling machine 7 is temporarily stored in the transfer area 8 as a second semi-finished bolt. After the second semi-finished bolt is taken out from the transfer area 8, it is processed by the quenching heating furnace 5 and the tempering heating furnace 6 in sequence, and the workpiece obtained after processing in the tempering heating furnace 6 is temporarily stored in the transfer area 8 again, so that the thread rolling thread forming process of the bolt is completed.

[0027] Among them, in order to improve the automation and intelligence level of the automatic bolt collection production line, in the aforementioned hot rolling thread forming process, the first to third conveying devices respectively convey the corresponding workpieces from the cold heading machine 1 to the vibration equipment 2, from the hot rolling equipment 4 to the quenching heating furnace 5, and from the quenching heating furnace 5 to the tempering heating furnace 6, and the first transfer device transfers the workpieces processed by the cold heading machine 1, the vibration equipment 2, and the degreasing equipment 3 in sequence as the first bolt semi-finished product from the degreasing equipment 3 to the transfer area 8, and the second transfer device transfers the first bolt semi-finished product from the transfer area 8 to the hot rolling equipment 4; in the aforementioned thread rolling thread forming process, the fourth conveying device transfers the corresponding workpiece from the cold heading machine 1 to the thread rolling machine 7, and the third transfer device transfers the corresponding workpiece from the thread rolling machine 7 to the transfer area 8.

[0028] Furthermore, the first to fourth conveying devices are all conveyor belts.

[0029] Specifically, the conveyor belt is an anti-collision large-angle conveyor belt, which can prevent the conveyed materials such as various workpieces from being bumped during the conveying process. In addition, various workpieces can be conveyed at large angles, and when conveying at large angles, it can ensure that various workpieces do not fall off the conveyor belt, so that the staff do not need to stack the various workpieces neatly on the conveyor belt, which can reduce the labor intensity of the staff.

[0030] Furthermore, the first to third transfer devices are all automatic guided vehicles (AGV for short).

[0031] Specifically, the automated guided vehicle is a dual-recognition automated guided vehicle, which has a drive device and a navigation device, can be automatically controlled through control software, can automatically transport materials such as various workpieces without manual operation, and can identify the transported materials and the transport direction of the materials, that is, realize dual recognition.

[0032] Furthermore, the cold heading machine 1 is specifically a 550t (ton) cold heading machine.

[0033] Figure 2 A schematic diagram showing a bolt automatic collection production line for thread rolling and screw thread forming process according to an embodiment of the utility model is shown. Figure 2 The cold heading machine 1 is controlled by the first electrical control cabinet 9; the thread rolling machine 7 is controlled by the second electrical control cabinet 10; and the quenching heating furnace 5 is controlled by the third electrical control cabinet 11.
