Description

Technical Field

[0001] This utility model relates to the field of heat treatment processing technology for screws, and in particular to a synchronous conveying device for heat treatment tickets. Background Technology

[0002] Heat treatment is a metal thermal processing technique that involves heating, holding, and cooling materials in a solid state to obtain the desired microstructure and properties. Typical heat treatment equipment includes a quenching furnace and a tempering furnace. For example, Chinese patent CN202010335913.4 discloses a process for processing hexagonal socket head cap screws. The heat treatment equipment includes a base, with a quenching furnace and a tempering furnace fixedly mounted on the top of the base. Two guide rails are fixedly mounted on the top of the base, passing through the quenching furnace and tempering furnace. A feeding rack is slidably connected to the top of the guide rails, and multiple material carrier nets are detachably connected to the feeding rack. The material carrier nets are horizontally arranged inside the feeding rack and are used to carry hexagonal socket head cap screws. An auxiliary feeding device and a pushing device are set at the end of the base top, away from the quenching furnace and tempering furnace. The auxiliary feeding device and the pushing device are located on both sides of the guide rails. This device can push the screws evenly so that they can be heated evenly. However, since the internal conditions of the quenching furnace and tempering furnace cannot be known from the outside, when producing screws of different batches continuously, it is easy to mix up the slips or invoices with the screw batch numbers, resulting in the use of the wrong screws during production, which affects the quality and performance of the assembled products. Utility Model Content

[0003] In view of this, the present invention provides a heat treatment ticket synchronous transmission device to solve the above problems.

[0004] A heat treatment ticket synchronous conveying device is used to ensure that screw blanks of the same batch can still correspond to an external ticket after heat treatment. The heat treatment ticket synchronous conveying device includes a control cabinet, a drive motor located at the output end of the control cabinet, a gear set located at the output end of the drive motor, and a chain belt mounted on the gear set. Several hanging plates are spaced apart on the side of the chain belt away from the heat treatment device, with each hanging plate corresponding to a link on the chain belt. Each hanging plate has a hanging hole, and the ticket is hung on the hanging plate via a hook.

[0005] Furthermore, the control cabinet contains a frequency converter.

[0006] Furthermore, the gear set includes a driving gear disposed at the output end of the drive motor, and a plurality of driven gears disposed on one side of the driving gear.

[0007] Furthermore, the driven wheels are divided into pairs, with the two driven wheels in the same group arranged vertically at intervals, the interval being the diameter of the driving wheel.

[0008] Furthermore, the heat treatment apparatus includes a conveyor belt that runs through the quenching furnace and the tempering furnace, and the conveying speed of the chain belt is matched with the conveying speed of the conveyor belt.

[0009] Furthermore, the feed section of the conveyor belt is angled, and several baffles are provided at intervals on the conveyor belt.

[0010] Compared with existing technologies, the heat treatment ticket synchronous conveying device provided by this utility model hangs the ticket in the hanging plate on the chain belt and controls the speed of the drive motor through the control cabinet, so that the conveying speed of the chain belt matches the conveying speed of the conveyor belt. This ensures that the ticket moves together with the screw blanks in the heat treatment device, thus ensuring that screw blanks of the same batch can still correspond to the ticket after heat treatment. At the same time, the position of the ticket can also be used to determine the position of the screw blanks in the heat treatment system at any time, so as to adjust and repair the machine when it stops working due to malfunction. Furthermore, the baffles on the conveyor belt can separate several screw blanks, so that the screws on the conveyor belt are evenly spread out, thereby ensuring that the screw blanks are heated evenly, thereby improving the hardness of the screws and reducing their internal stress.

[0014] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0015] like Figure 1The diagram shown is a structural schematic of the heat treatment ticket synchronous conveying device provided by this utility model. The heat treatment ticket synchronous conveying device includes a control cabinet 10, a drive motor 20 disposed at the output end of the control cabinet 10, a gear set 30 disposed at the output end of the drive motor 20, and a chain belt 40 mounted on the gear set 30. It is conceivable that the heat treatment ticket synchronous conveying device also includes other functional modules, such as a power supply module, a screw module, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0016] Please refer to the following: Figure 2 and Figure 3 It should be noted that the heat treatment ticket synchronous conveying device is used to distinguish screw blanks of different batches in the heat treatment system. Screw blanks of the same batch can still correspond to an external ticket 50 after heat treatment, thereby avoiding the situation where the batch number of the screw blank and the ticket 50 are mixed up. This heat treatment device includes a quenching furnace 60 and a tempering furnace 70. The heat treatment device itself is prior art, and its internal structure and working principle will not be described in detail here.

[0017] The control cabinet 10 has a frequency converter inside, which can adjust the output frequency to control the speed of the drive motor 20, so that the speed of the drive motor 20 can match the conveying speed in the heat treatment, so that the conveying speed of the ticket 50 is consistent with the conveying speed of its corresponding screw blank.

[0018] The gear set 30 includes a driving gear 31 disposed at the output end of the drive motor 20, and a plurality of driven gears 32 disposed on one side of the driving gear 31.

[0019] The drive wheel 31 is driven by the drive motor 20 to complete its rotation. One end of the chain belt 40 is sleeved on the drive wheel 31, so that the drive wheel 31 rotates to drive the chain belt 40 for conveying.

[0020] The driven wheel 32 is disposed on one side of the heat treatment device and corresponds to the conveying route in the heat treatment system. Several driven wheels 32 are divided into pairs, with two driven wheels 32 in the same pair arranged vertically at intervals, the interval being the diameter of the driving wheel 31. Thus, the upper and lower driven wheels 32 respectively support the upper and lower chains of the chain belt 40, so that the length and shape of the chain 40 correspond to the conveying route in the heat treatment system.

[0021] On the side of the chain belt 40 away from the heat treatment device, several hanging plates 41 are spaced apart, each hanging plate 41 corresponding to a link on the chain belt 40. Each hanging plate 41 has a hanging hole, and the slip 50 is hung on the hanging plate 41 via a hook 51. Driven by the drive wheel 31, the upper and lower chains of the chain belt 40 move forward and backward respectively. By hanging the slip 50 on the forward chain of the chain belt 40, the slip 50 moves with the screw blanks in the heat treatment device, ensuring that screw blanks of the same batch can still correspond to the slip 50 after heat treatment. Simultaneously, the position of the slip 50 allows for real-time determination of the screw blank position in the heat treatment system, facilitating machine adjustment and repair when a malfunction occurs.

[0022] In the heat treatment apparatus, a conveyor belt 80 runs through the quenching furnace 60 and the tempering furnace 70 to transport screw blanks. The feed section of the conveyor belt 80 is angled, and several baffles 81 are spaced out on the conveyor belt 80. When the screw blanks are poured onto the feed section of the conveyor belt 80, they fall downwards due to gravity. The baffles 81 block a small portion of the screw blanks from falling, thus accumulating the screw blanks layer by layer. This separates several screw blanks, ensuring that the screws on the conveyor belt 80 are evenly spread out. This guarantees the consistency of the number of screw blanks in the interval area, ensuring that the screw blanks are heated evenly during the quenching process, improving the hardness of the screws and reducing their internal stress.

[0023] Compared with the prior art, the heat treatment ticket synchronous conveying device provided by this utility model hangs the ticket in the hanging plate 41 on the chain belt 40, and controls the speed of the drive motor 20 through the control cabinet 10, so that the conveying speed of the chain belt 40 matches the conveying speed of the conveyor belt 80. This ensures that the ticket 50 moves together with the screw blanks in the heat treatment device, thereby ensuring that screw blanks of the same batch can still correspond to the ticket 50 after heat treatment. At the same time, the position of the ticket 50 can also be used to determine the position of the screw blanks in the heat treatment system at any time, so as to adjust and repair the machine when it stops working due to malfunction. In addition, the baffle 81 on the conveyor belt 80 can separate several screw blanks, so that the screws on the conveyor belt 80 are evenly spread out, thereby ensuring that the screw blanks are heated evenly, thereby improving the hardness of the screws and reducing their internal stress.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
