Description

Technical Field

[0001] The invention relates to the technical field of brass processing equipment, in particular to a brass strip annealing machine. Background Art

[0002] Brass is a metal alloy that combines copper and zinc in different proportions and is widely used in the field of decoration. Its composition can be adjusted to adjust the color tone of brass. As the width of brass strip increases, it will bring a series of adverse effects to rolling, heat treatment, and surface quality control, such as being more prone to warping and deformation, uneven heat treatment, and more prone to defects such as flaws and cracks. For wide brass strips, it is more difficult to achieve uniform heat treatment, and advanced heating equipment and processes are required to ensure that the entire plate is heated evenly during the heat treatment process.

[0003] The heat treatment process includes annealing. Since the brass strips are produced continuously, they need to be annealed continuously. If the brass strips are added to the same annealing mechanism one after another, it is easy to distinguish which one is put in first and which one is put in later. When taking out the brass strips, it is easy to take out the brass strips that have not completed annealing. Summary of the invention

[0004] In view of this, the object of the present invention is to provide a brass strip annealing machine to solve the problem that it is difficult to distinguish the order when annealing the brass strip.

[0005] Based on the above-mentioned purpose, the present invention provides a brass strip annealing machine, comprising an insulation shell, which is arranged on the ground, and has a feed port and a discharge port on both end sides respectively; a partition plate, which is arranged inside the insulation shell, and divides the inside of the insulation shell into a heating chamber and an insulation chamber; a connecting hole is provided on the partition plate, and the heating chamber and the insulation chamber are connected through the connecting hole; a transport module, which passes through the feed port, the connecting hole and the discharge port, and is used to transport the brass strip to be annealed into the insulation shell for annealing; a heating module, which is arranged in the heating chamber, and heats the temperature in the heating chamber.

[0006] As a further improvement of the present application, the heat-insulating shell includes a shell layer arranged on the outside, a heat-insulating layer arranged on the inner surface of the shell layer, and a protective layer arranged on the inner surface of the heat-insulating layer.

[0007] As a further improvement of the present application, the partition board includes an inner layer board and a protective board wrapped around the outside of the inner layer board, and the inner layer board is made of a thermal insulation material.

[0008] As a further improvement of the present application, the heating module includes a plurality of heating tubes, and the plurality of heating tubes are evenly distributed on the inner walls of the upper part and both sides of the heating chamber.

[0009] As a further improvement of the present application, the transport module includes a mounting bracket; a driving shaft, which is arranged on the mounting bracket; a driven shaft, which is arranged on the mounting bracket; a conveyor belt, which is arranged on the driving shaft and the driven shaft and passes through the feed port, the connecting hole and the discharge port; a conveying motor, which is arranged outside the insulation shell, and its output shaft is dynamically connected to one end of the driving shaft.

[0010] As a further improvement of the present application, sprockets are respectively provided on the driving shaft and the driven shaft, and a chain that cooperates with the sprockets for transmission is provided on the conveyor belt.

[0011] As a further improvement of the present application, the conveyor belt is provided with stoppers at intervals, and a brass belt requiring annealing is installed on each of the stoppers.

[0012] As a further improvement of the present application, the limiter includes two U-shaped clips, and the two U-shaped clips are arranged side by side on the same row of the conveyor belts, and the openings of the U-shaped clips are upward.

[0013] The beneficial effects of the present invention are as follows: the brass strips to be annealed are brought into the heating chamber by the transport module for heating to reach the annealing temperature, and then sent to the heat preservation chamber for heat preservation annealing. After the annealing is completed, the strips leave the heat preservation shell from the discharge port, and finally detach from the transport module to complete the annealing process. In this way, the brass strips are successively withdrawn from the brass strip annealing machine according to the order in which they enter, so that the annealing consistency of all the brass strips is maintained well.

[0022] like Figure 1-3 As shown, a brass strip annealing machine comprises a heat-insulating shell 1, which is arranged on the ground, and a feed port and a discharge port are respectively provided on the sides at both ends; a partition plate 2, which is arranged inside the heat-insulating shell 1, and divides the inside of the heat-insulating shell 1 into a heating chamber 21 and a heat-insulating chamber 22; a connecting hole 23 is provided on the partition plate 2, and the heating chamber 21 is connected with the heat-insulating chamber 22 through the connecting hole 23; a transport module, which passes through the feed port, the connecting hole 23 and the discharge port, and is used to transport the brass strip to be annealed into the heat-insulating shell 1 for annealing operation; a heating module, which is arranged in the heating chamber 21, and heats the temperature in the heating chamber 21.

[0023] The brass to be annealed is brought into the heating chamber 21 by the transport module for heating until the temperature reaches the annealing temperature, and then sent to the insulation chamber 22 for insulation annealing. After annealing, it leaves the insulation shell 1 from the discharge port and finally detaches from the transport module to complete the annealing process.

[0024] In order to keep warm and avoid scratches, the heat-insulating shell 1 includes a shell layer 11 arranged on the outside, a heat-insulating layer 12 arranged on the inner surface of the shell layer 11 , and a protective layer 13 arranged on the inner surface of the heat-insulating layer 12 .

[0025] Similarly, the partition plate 2 includes an inner layer plate 24 and a protective plate 25 wrapped around the outer side of the inner layer plate 24, and the inner layer plate 24 is made of a heat-insulating material.

[0026] In order to heat evenly, the heating module includes a plurality of heating tubes, and the plurality of heating tubes are evenly distributed on the inner walls of the upper part and both sides of the heating chamber 21. Dispersed multi-point heating avoids the defect of inconsistent temperature at various locations caused by excessive temperature concentration.

[0027] In order to achieve transportation, the transportation module includes a mounting bracket 31; a driving shaft 32, which is arranged on the mounting bracket 31; a driven shaft 33, which is arranged on the mounting bracket 31; a conveyor belt 34, which is arranged on the driving shaft 32 and the driven shaft 33, and passes through the feed port, the connecting hole 23 and the discharge port; a conveying motor 35, which is arranged outside the insulation shell 1, and its output shaft is dynamically connected to one end of the driving shaft 32.

[0028] In order to rotate synchronously and transmit motion, sprockets 36 are respectively provided on the driving shaft 32 and the driven shaft 33 , and a chain 37 that cooperates with the sprockets 36 for transmission is provided on the conveyor belt 34 .

[0029] In order to limit the movement of the brass strip on the conveyor belt 34, the conveyor belt 34 is provided with stoppers 4 at intervals, and a brass strip that needs to be annealed is installed on each of the stoppers 4.

[0030] The stopper 4 includes two U-shaped clips 41 . The two U-shaped clips 41 are arranged side by side on the same row of the conveyor belts 34 , and the openings of the U-shaped clips 41 face upward.

[0031] In order to facilitate loading, the brass strip annealing machine also includes a loading plate, which is tilted and arranged obliquely above the feed port. The lower end of the loading plate faces the conveyor belt 34, and the brass strip falls from the loading plate and enters the U-shaped clip 41.
