Abstract
Description
Technical Field
[0001] This utility model relates to the field of tempering technology, specifically to a novel automatic tempering device for railings. Background Technology
[0002] Tempering is a metal heat treatment process that involves reheating a quenched workpiece to a suitable temperature below the lower critical temperature Ac1 (the temperature at which pearlite begins to transform into austenite during heating), holding it at that temperature for a period of time, and then cooling it in air, water, or oil. Alternatively, it involves heating a quenched alloy workpiece to a suitable temperature, holding it at that temperature for a certain period, and then slowly or rapidly cooling it. It is generally used to reduce or eliminate internal stress in quenched steel parts, or to reduce their hardness and strength to improve their ductility or toughness. Currently, most tempering of metals is done manually by holding the metal with clamping tools. Some automated tempering devices use chain conveyors to transport railings. However, because the chain conveyors create spatial barriers during transport, they can affect the heating rate of the railings, posing a problem. Utility Model Content

Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0019] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
[0020] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” may be used herein to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific implementation of this utility model will be described in detail below with reference to specific embodiments: such as Figures 1-5The present invention is achieved through the following technical solution: a novel automatic tempering device for railings, comprising a tempering furnace 4, a transmission device, and an adjusting structure. One end of the tempering furnace 4 is fixedly connected to a feeding rack 17, and the other end is fixedly connected to a discharging rack 3. Several rotating shafts 1 are rotatably connected to the discharging rack 3. Several rotating shafts 1 are rotatably connected inside the tempering furnace 4, and a conveying roller 2 is fixedly connected to each rotating shaft 1. The conveying roller 2 is thinner in the middle and thicker at both ends. The adjusting structure includes a mounting base 18, and mounting bases 1 are fixedly connected to both sides of the feeding rack 17. 8. Two optical shafts 16 are fixedly connected between two mounting bases 18. A first slider 6 and a second slider 21 are slidably connected on the optical shafts 16. A clamping plate 8 is fixedly connected to the first slider 6 and the second slider 21 respectively. A screw 5 is rotatably connected between the two mounting bases 18. The screw 5 is threaded to the first slider 6 and the second slider 21. The threads on the first slider 6 and the second slider 21 are opposite. A servo motor 7 is fixedly connected to the mounting base 18. The rotating shaft of the servo motor 7 is fixedly connected to the screw 5 through a coupling. The adjustment structure is provided with two bases.
[0023] Several sets of transmission devices are installed on the discharge rack 3 and the tempering furnace 4. The transmission devices include a drive sprocket 14, a driven sprocket 11, a chain 12 and a first motor 13. The drive sprocket 14 and the driven sprocket 11 are respectively fixedly connected to two adjacent rotating shafts 1. The drive sprocket 14 and the driven sprocket 11 are connected by the chain 12. The rotating shaft of the first motor 13 is fixedly connected to the rotating shaft 1 with the drive sprocket 14 by a coupling.
[0024] A chain plate 19 is provided on the feeding rack 17. The sprocket of the chain plate 19 is rotatably connected to the feeding rack 17.

The infrared sensor 20 is connected to the controller via a signal line. The controller is connected to the servo motor 7 via a signal line. The controller is set so that when the infrared sensor 20 is blocked, the controller controls the servo motor 7 to rotate forward, causing the two sliders and the clamping plate 8 to move inward. The clamping plate 8 stops when it is aligned with the outer side of the conveying roller 2. When the infrared sensor 20 is not blocked, the controller controls the servo motor 7 to rotate in reverse, causing the two sliders and the clamping plate 8 to move outward. The clamping plate 8 stops when it is aligned with one side of the mounting base 18.

The second motor 15 is started, and the chain plate 19 transports the railing into the tempering furnace 4. When one end of the railing blocks the infrared sensor 20, the two clamping plates 8 move inward to align with the conveying roller 2. At the same time, the position of the railing is adjusted. The two adjustment structures work simultaneously. After adjustment, the railing is aligned with the conveying roller 2 and enters the tempering furnace 4 directly along the conveying roller 2. The first motor 13 is started, and the conveying roller 2 transports the railing to the discharge rack.
