Description

Technical Field

[0001] This utility model relates to the field of tempering furnace technology, and in particular to an automatic feeding machine. Background Technology

[0002] A tempering furnace is a key piece of equipment used for heat treatment of metallic materials. By precisely controlling temperature and time, it improves the internal structure and mechanical properties of metals, reduces the internal stress caused by quenching, prevents cracking and deformation, and enhances toughness, plasticity, and impact resistance while maintaining a certain strength and hardness. It is widely used in industrial manufacturing fields, such as steel materials (tool steel, mold steel, spring steel, etc.), including mechanical parts, electronic components, molds, and measuring tools.

[0003] After heat treatment in the tempering furnace, the workpieces are unloaded by a conveying device. However, the workpieces still have a certain surface temperature when they are conveyed out of the tempering furnace. The workpieces with residual heat cannot directly enter the next process (such as sandblasting or machining). A buffer area needs to be reserved for the workpieces to wait for them to cool down. The heat radiation from the residual heat workpieces will also seriously reduce the cooling rate, resulting in a reduction in single-line production capacity. Therefore, an automatic unloading machine is proposed. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the present invention solves the problems mentioned in the background art through the following technical solution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic feeding machine, comprising:

[0008] The material feeding conveyor body has side plates fixedly connected to both sides of the top of the material feeding conveyor body, and three ear plates are fixedly connected to the top of the two side plates on opposite sides. The top of the ear plates is fixedly connected to a column.

[0009] A cooling component is provided between the two opposing columns, and a horizontal cooling pipe is fixedly connected between the three cooling components.

[0011] In a preferred embodiment of the automatic feeding machine provided by this utility model, the cooling component includes a longitudinal cooling pipe located between two opposing columns. Sliding sleeves are slidably connected to the surface of the columns, and both ends of the longitudinal cooling pipe are fixedly connected to the corresponding sliding sleeves.

[0012] In a preferred embodiment of the automatic feeding machine provided by this utility model, the horizontal cooling pipe is fixedly connected horizontally between the three vertical cooling pipes and communicates with the inner cavity of the three vertical cooling pipes.

[0013] In a preferred embodiment of the automatic feeding machine provided by this utility model, the bottom of both the longitudinal cooling pipe and the bottom of the transverse cooling pipe are provided with a number of air outlets.

[0014] In a preferred embodiment of the automatic feeding machine provided by this utility model, the slot is opened on both sides of the two middle sliding sleeve surfaces, and the inner cavity of the slot is arc-shaped.

[0015] In a preferred embodiment of the automatic feeding machine provided by this utility model, the positioning component includes a clamp that is movably connected to the inner cavities of two slots on the surface of the sliding sleeve.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model provides an automatic feeding machine. The feeding conveyor conveys the workpieces after tempering furnace treatment. At the same time as feeding, the surface of the workpieces is air-cooled by several longitudinal and transverse cooling pipes. The longitudinal / transverse combination forms a three-dimensional air field, which improves the heat transfer coefficient of the workpiece surface and greatly shortens the cooling time of the workpieces. In addition, the height of the longitudinal and transverse cooling pipes can be adjusted to suit different cooling needs.

[0021] This utility model provides an automatic feeding machine that, while performing air cooling, transports the workpiece on the surface of the feeding conveyor body. After passing through the surface of multiple buffer plates, it is buffered by spring sheets. On the one hand, it can prevent the workpiece from being damaged by excessive impact when it is fed from a high place to a low place on the surface of the feeding conveyor body. On the other hand, it forces the workpiece to move along an S-shaped path, extending the transportation distance and ensuring that the workpiece is continuously and efficiently cooled in the extended path.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 An automatic feeding machine includes: a feeding conveyor body 1, with side plates 3 fixedly connected to both sides of the top of the feeding conveyor body 1, and three ear plates 4 fixedly connected to the top of the opposite side of the two side plates 3, with columns 5 fixedly connected to the top of the ear plates 4; a cooling component 6 is provided between the two opposing columns 5, and a horizontal cooling pipe 7 is fixedly connected between the three cooling components 6; multiple insertion holes 8 are opened on the surface of the two middle columns 5, and notches 9 and slots 10 are opened on the surface of the two middle sliding sleeves 62. The notches 9 facilitate the user to determine the specific position of the insertion holes 8, and positioning components 11 are provided on their surface; and delay components 12 are provided on the opposite side of the two side plates 3.

[0033] In this embodiment, lifting brackets 2 are fixedly installed at the four corners of the bottom of the feeding conveyor body 1 for independent height adjustment of both sides of the feeding conveyor body 1. The cooling component 6 includes a longitudinal cooling pipe 61 located between two opposing columns 5. A sliding sleeve 62 is slidably connected to the surface of the column 5. The longitudinal cooling pipe 61 is slidably connected to the column 5 through the sliding sleeve 62 to achieve longitudinal height adjustment. The front and rear ends of the longitudinal cooling pipe 61 are fixedly connected to the corresponding sliding sleeve 62. A transverse cooling pipe 7 is horizontally fixedly connected between the three longitudinal cooling pipes 61 and communicates with the inner cavity of the three longitudinal cooling pipes 61. The transverse cooling pipe 7 balances the air pressure of each longitudinal cooling pipe 61 to ensure uniform airflow. The bottom of the longitudinal cooling pipe 61 is connected to the vertical cooling pipe 61. Several air outlets are provided at the bottom of the horizontal cooling pipe 7. The air outlets at the bottom directly impact the surface of the workpiece, improving the heat exchange efficiency. The slots 10 are located on both sides of the surface of the two middle sliding sleeves 62, and the inner cavity of the slots 10 is arc-shaped. The slots 10 play a positioning role for the clamps 111, improving the stability of the connection between the clamps 111 and the sliding sleeves 62. The positioning component 11 includes clamps 111 that are movably connected to the inner cavity of the two slots 10 on the surface of the sliding sleeves 62. The shape of the clamps 111 is adapted to the inner cavity of the slots 10. A locking post 112 is fixedly inserted through the surface of the clamps 111. One end of the locking post 112 is inserted into the corresponding insertion hole 8, and the other end of the locking post 112 is fixedly connected to a pull block 113.

[0034] In the embodiments of this application, the delay component 12 includes several buffer plates 121 rotatably connected to the opposite side of the two side plates 3 via a rotating shaft, forming a multi-level buffer structure. When the workpiece impacts the buffer plate 121, the rotating shaft absorbs energy and reduces the impact force. The multiple buffer plates 121 force the workpiece to be transported along an S-shaped path, extending the cooling path. Several balls 122 are installed on the outer side of the buffer plate 121 to form a sliding contact surface, preventing the workpiece from getting stuck and improving the transport efficiency. The several buffer plates 121 located on the front side and the several buffer plates 121 located on the rear side are symmetrically and staggeredly distributed. A spring sheet 123 is fixedly installed on the inner side of the buffer plate 121. One side of the spring sheet 123 is fixedly connected to the side plate 3. The spring sheet 123 provides the buffer plate 121 with a rebound force. By replacing the spring sheets 123 with different stiffness, it can be adapted to workpieces of different weights.

[0035] The automatic feeding machine provided by this utility model is used as follows: Before air cooling, the horizontal cooling pipe 7 is connected to the external air supply pipe. The workpiece after tempering furnace treatment is fed from high to low through the feeding conveyor body 1. During the conveying process, multiple buffer plates 121 force the workpiece to move along an S-shaped path, extending the transport distance and the contact time with air cooling. The air outlets at the bottom of the horizontal cooling pipe 7 and the bottom of the vertical cooling pipe 61 air cool the passing workpiece, thereby cooling the surface of the workpiece. The height of the vertical cooling pipe 61 and the horizontal cooling pipe 7 can also be adjusted according to the cooling requirements of the workpiece. The locking pin 112 is pulled out from the inner cavity of the insertion hole 8, and at the same time the clamp 111 is disengaged from the slot 10, so that the horizontal cooling pipe 7, the vertical cooling pipe 61 and the sliding sleeve 62 can be pushed to slide on the surface of the column 5, and the height is changed. Finally, by inserting the locking pin 112 into the insertion hole 8 of the corresponding height and the clamp 111 is locked in the inner cavity of the slot 10, the height can be locked and the adjustment is completed.
