Description

Technical Field

[0001] This application relates to the field of tempering furnace technology, and more specifically, to a tempering device for improving the toughness of pneumatic nails. Background Technology

[0002] In the prior art, for example, a tempering furnace for saw blade substrates disclosed in CN209685867U includes a furnace body and a furnace door that is sealed to the opening of the furnace body. The furnace door and the furnace body form a sealed cavity, and a heating device is provided in the sealed cavity. The key technical points are: multiple clamping devices are provided in the sealed cavity, wherein the clamping device includes a platform set at the bottom of the furnace body, a positioning shaft is fixedly provided at the center of the platform, the positioning shaft passes through multiple partitions, and multiple saw blade substrates are stacked between two adjacent partitions; multiple first heat conduction holes are opened circumferentially along its diameter direction on the platform, the positioning shaft is hollow inside and connected to the first heat conduction holes, and multiple through holes are evenly spaced on the outer wall of the positioning shaft.

[0003] This method allows the saw blade substrate to be heated more evenly in the tempering furnace, enabling the internal residual stress to be eliminated more thoroughly, thereby improving the strength and toughness of the saw blade.

[0004] However, it can only be used for tempering sheet-shaped or ring-shaped objects, and cannot be used for tempering long strip-shaped (pneumatic nail) objects as described in this application. Therefore, the applicability of this solution is relatively limited. Utility Model Content

[0005] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a tempering device to improve the toughness of pneumatic nails, aiming to overcome the problem that an existing tempering furnace for saw blade substrates is unsuitable for tempering long, strip-shaped objects.

[0006] This application proposes a tempering device for improving the toughness of pneumatic nails, comprising a furnace body, a furnace cover sealed at the top of the furnace body, a central power shaft coaxially disposed within the furnace body, one end of the central power shaft extending out of the furnace body and externally connected to a drive device for rotation; a plurality of loading components are axially and uniformly disposed within the furnace body, a plurality of bearing plates are axially and uniformly distributed on the loading components, and a plurality of through holes are uniformly disposed on the bearing plates; the loading components and the central power shaft are connected by a drive.

[0007] According to an embodiment of this application, a tempering device for improving the toughness of pneumatic nails has the following advantages: by using a blower to guide airflow through a guide element, the airflow in the entire furnace body is circulated, thereby allowing the heat concentrated in the direction of the furnace cover to be evenly distributed in the furnace body. The rotation of the central power shaft drives the rotation of multiple loading components on the periphery, which in turn allows the pneumatic nails on multiple bearing plates to be heated as evenly as possible.

[0008] In addition, a tempering device for improving the toughness of pneumatic nails according to an embodiment of this application also has the following additional technical features: In some specific embodiments of this application, the flow guide is coaxially fixed to the inner wall of the furnace body and is arranged in a spiral shape, and the air outlet of the blower is inclined along the upper end surface of the flow guide.

[0009] In some specific embodiments of this application, a bottom drive assembly is provided at the bottom of the furnace body. The bottom drive assembly includes a bottom gear ring fixed to the furnace body, an end face limiting ring fixed to the upper end face of the bottom gear ring, and an end face limiting plate provided on the inner side of the end face limiting ring.

[0010] In some specific embodiments of this application, the inner diameter of the bottom gear ring is larger than the inner diameter of the end face limiting ring, and a gap is left between the end face limiting ring and the end face limiting plate.

[0011] In some specific embodiments of this application, the central power shaft includes a rotating shaft and a connecting shaft coaxially fixedly connected. The rotating shaft passes through the end face limiting plate and is coaxially fixedly connected to a drive gear. The connecting shaft extends out of the furnace cover and is externally connected to a drive device.

[0012] In some specific embodiments of this application, the loading assembly includes a loading shaft for carrying a plurality of the carrier discs. The loading shaft passes through the gap between the end face limiting ring and the end face limiting plate and is coaxially fixed to a driven gear, which meshes with the driving gear.

[0013] In some specific embodiments of this application, the passive gear and the bottom gear ring mesh.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] like Figures 1-4 As shown, a tempering device for improving the toughness of pneumatic nails according to an embodiment of this application includes a furnace body 1, and a furnace cover 11 is sealed at the top of the furnace body 1. It should be noted that, in a specific embodiment of this application, a heating device is provided inside the furnace body 1 to make the internal temperature of the furnace body 1 reach the temperature for tempering pneumatic nails.

[0020] A central power shaft 3 is coaxially arranged inside the furnace body 1. One end of the central power shaft 3 extends out of the furnace body 1 and is connected to an external drive device to rotate. Multiple loading components 4 are evenly arranged axially inside the furnace body 1. Multiple bearing plates 43 are evenly distributed axially on the loading components 4. Multiple through holes are evenly arranged on the bearing plates 43. The loading components 4 and the central power shaft 3 are connected by a drive.

[0021] Specifically, in some specific embodiments of this application, the guide member 12 is coaxially fixed to the inner wall of the furnace body 1 and is arranged in a spiral shape, and the air outlet end of the blower is inclined along the upper end surface of the guide member 12.

[0022] It is understandable that when the blower blows air to the top of the guide 12, most of the airflow will flow along the spiral path of the guide 12, thus forming a certain range of spiral downward airflow inside the entire furnace body 1. It is further understandable that this airflow will carry heat and rush it downwards from the furnace body 1 to prevent the heat from rising and causing uneven heat distribution inside the furnace body 1.

[0023] In some specific embodiments of this application, a bottom drive assembly 2 is provided at the bottom of the furnace body 1. The bottom drive assembly 2 includes a bottom gear ring 21 fixed to the furnace body 1. An end face limiting ring 22 is fixed to the upper end face of the bottom gear ring 21. An end face limiting plate 23 is provided on the inner side of the end face limiting ring 22.

[0024] Furthermore, the inner diameter of the bottom gear ring 21 is larger than the inner diameter of the end face limiting ring 22, and there is a gap between the end face limiting ring 22 and the end face limiting plate 23.

[0025] The central power shaft 3 includes a rotating shaft 31 and a connecting shaft 32 that are coaxially fixed together. The rotating shaft 31 passes through the end face limiting plate 23 and is coaxially fixed with a drive gear 311. The connecting shaft 32 extends out of the furnace cover 11 and is externally connected to a drive device.

[0026] Therefore, it can be seen that when the external drive device drives the connecting shaft 32 to rotate, it will synchronously drive the rotating shaft 31 and the drive gear 311 to rotate.

[0027] like Figure 1 and Figure 3 As shown, in some specific embodiments of this application, the loading assembly 4 includes a loading shaft 41 for carrying a plurality of carrier discs 43. The loading shaft 41 passes through the gap between the end face limiting ring 22 and the end face limiting plate 23 and is coaxially fixed to a driven gear 42. The driven gear 42 meshes with the driving gear 311 and the bottom gear ring 21.

[0028] It should be noted that the connection between the loading shaft 41 and the driven gear 42 can be detachable to facilitate the installation and removal of multiple bearing plates 43 and the placement or removal of pneumatic nails.

[0029] Therefore, when the driving gear 311 rotates, it will drive the multiple passive gears 42 on the periphery to rotate. Under the action of the bottom gear ring 21 on the periphery, the multiple passive gears 42 will rotate on their own axis and revolve around the wheel between the bottom gear ring 21 and the driving gear 311. It can be understood that in this case, multiple sets of loading components 4 will rotate on their own axis and revolve around the wheel synchronously. In this way, the pneumatic nails placed on the multiple bearing plates 43 can be heated more evenly.

[0030] It should be noted that in the specific embodiments of this application, the support plate 43 is provided with multiple axial holes so that heat can pass through the holes axially. At the same time, the pneumatic nail can be vertically inserted into the holes or horizontally placed on the support plate 43 so that the pneumatic nail can be better heated.

[0031] In some specific embodiments of this application, an axial limiting cylinder 44 is provided between multiple bearing plates 43, the axial limiting cylinder 44 is damped and slidably sleeved on the loading shaft 41, and the axial limiting cylinder 44 has axial extension and retraction capability.

[0032] Understandably, the telescopic capability of the axial limiting cylinder 44 allows the spacing between multiple bearing discs 43 on the same loading shaft 41 to be adjusted to suit different pneumatic nails or different products.

[0033] Of course, during the actual tempering process, external equipment or other equipment can be used to expel the oxygen inside the furnace body 1 and fill it with inert gas to prevent the pneumatic nails from oxidizing during the tempering process. After the tempering operation is completed, it can be cooled naturally. Then, the furnace cover 11 can be opened and the support plate 43 can be taken out. The specific operation method will not be described in detail here.

[0034] It should be noted that the specific model specifications of the bottom gear ring 21, the driving gear 311, and the driven gear 42 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0035] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
