Description

Technical Field

[0001] The invention relates to the technical field of brass strip processing, in particular to an anti-oxidation uniform annealing device and application thereof in the preparation of the brass strip. Background Art

[0002] Brass strip has excellent electrical conductivity, thermal conductivity, machinability and corrosion resistance, making it play an indispensable role in electronics, electrical, heat exchange, construction, decoration, automobiles, aviation and musical instrument manufacturing.

[0003] In the production process of brass strip, annealing is an important step. Annealing can eliminate the internal stress of the brass strip. During annealing, both sides of the brass strip need to be heated. In order to prevent the brass strip from oxidizing after heating, anti-oxidation gas needs to be sprayed on the heated brass strip.

[0004] Taking into account that the production specifications of brass strips are different and their widths are also different, the width of the gas delivery port of the anti-oxidation gas injection device in the traditional annealing equipment is constant. When the width of the brass strip is wider, the edge of the brass strip is only treated with anti-oxidation by the diffusion of the anti-oxidation gas impacting the brass strip. However, the direction of the diffusion of the gas is uncertain, which can easily lead to local oxidation at the edge of the brass strip. Summary of the invention

[0015] The traction assembly further comprises two sets of abutment structures which are arranged on the first bracket and matched with the support roller, and the abutment structures can straighten the brass strip when the brass strip is pulled.

[0018] As a further solution of the present invention: the rotation axis of the roller wheel intersects with the projection of the rotation axis of the support roller on the base;

[0019] The ends of the rotating shafts of the two groups of rollers that are away from each other are located on a side of the supporting roller that is away from the winding structure.

[0020] As a further solution of the present invention: the heating assembly includes a second bracket fixedly mounted on the base, the second bracket is symmetrically provided with two slide grooves, a slider is slidably mounted in the slide groove, and the slider is connected to a double-headed electric telescopic rod arranged on the second bracket;

[0021] Two groups of parallel flame spraying devices are installed on the two groups of slide blocks, and the distance between the brass belt and the two groups of flame spraying devices is the same when the brass belt is pulled.

[0022] As a further solution of the present invention: the blocking rod comprises a blocking shaft slidably arranged through the regulating box, one end of the blocking shaft is connected to the abutment plate, and the other end of the blocking shaft is adapted to the gas delivery port, and when the abutment plate moves away from the regulating box, the blocking shaft can make the gas delivery port conductive;

On the one hand, it can prevent the width range that the anti-oxidation gas can act on from being lower than the width of the brass strip, causing oxidation at the edge of the brass strip; on the other hand, it can prevent the width range that the anti-oxidation gas can act on from being higher than the width of the brass strip, causing waste of the anti-oxidation gas.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0045] See also Figures 1 to 10 In an embodiment of the present invention, an anti-oxidation uniform annealing device includes: a base 1, a heating component, an adjustment box 22, a blocking rod and an abutment plate 24, so that when the second electric telescopic rod 17 moves, it can drive the connecting plate 21 to move, and under the action of two adjacent abutment plates 24, the gas delivery ports 2201 are turned on one by one in sequence, thereby increasing the width range that the anti-oxidation gas can act on and matching it with the width of the brass strip. On the one hand, it can prevent the width range that the anti-oxidation gas can act on from being lower than the width of the brass strip, causing oxidation at the edge of the brass strip. On the other hand, it can prevent the width range that the anti-oxidation gas can act on from being higher than the width of the brass strip, causing waste of the anti-oxidation gas. The details are as follows:

[0046] The base 1 is provided with a traction assembly for pulling the brass strip to move, the traction assembly includes a plurality of first brackets 2 arranged on the base 1, support rollers 3 and guide rollers 10 are rotatably mounted on the first brackets 2, a winding structure is provided at one end of the guide roller 10 away from the support roller 3, the winding structure includes a driving motor 12 installed on the base 1, and the output shaft of the driving motor 12 is connected to a winding roller 11;

[0047] The plane formed by the rotating shaft of the support roller 3 and the rotating shaft of the guide roller 10 is parallel to the upper surface of the base 1, and the support roller 3 and the guide roller 10 have the same diameter, so that when the brass strip is pulled, the brass strip can be parallel to the upper surface of the base 1;

[0048] A first electric telescopic rod 4 is fixedly mounted on the first bracket 2, and an action end of the first electric telescopic rod 4 is connected to a connecting shaft 5 that penetrates the first bracket 2 and is slidably arranged, and a guide groove 501 is arranged along the length direction of the connecting shaft 5, and the guide groove 501 cooperates with the first bracket 2 to prevent the connecting shaft 5 from deflecting, thereby ensuring the abutment stability between the roller 8 and the supporting roller 3;

[0049] The traction assembly also includes two sets of abutment structures arranged on the first bracket 2 and adapted to the support roller 3, the abutment structures can make the brass belt straight when the brass belt is pulled, the abutment structure includes a transverse frame 6 connected to the action end of the first electric telescopic rod 4, a slideway 601 is formed on the transverse frame 6, a sliding connection 7 is slidably installed in the slideway 601, a roller 8 is rotatably installed on the sliding connection 7, and a plurality of counterweights 9 are fixed on the side of the sliding connection 7 away from the roller 8. It should be added that the function of the counterweight 9 is to increase the force of the roller 8 acting on the brass belt, so the counterweight 9 can also be replaced by an elastic member such as a spring, and the elastic member is used to make the sliding connection 7 have a downward movement force;

[0050] Specifically, the rotation axis of the roller 8 intersects with the projection of the rotation axis of the support roller 3 on the base 1 ; and the ends of the rotation axes of the two groups of rollers 8 that are away from each other are located on the side of the support roller 3 away from the winding roller 11 .

[0051] In the initial state, the brass strip to be annealed is wound onto the winding roller 11 via the support roller 3 and the guide roller 10, that is, when the drive motor 12 is working, it can drive the winding roller 11 to rotate. It should be noted that, considering that the thickness of the brass strip on the winding roller 11 gradually increases as the winding proceeds, the linear speed of the brass strip wound on the outside of the winding roller 11 gradually increases when rotating, which will cause the speed of the winding roller 11 to increase when pulling the brass strip, and cause the temperature of the brass strip to be insufficient when heated. Therefore, the above-mentioned drive motor 12 adopts a variable speed motor, and its rotation speed is inversely proportional to the thickness of the brass strip wound on the winding roller 11, so that the brass strip can be pulled at a uniform speed, so that the brass strip can be heated evenly when heated, thereby improving the overall annealing effect.

[0052] When the brass strip is pulled, the end of the brass strip away from the winding roller 11 is in a state of being clamped by the roller 8 and the support roller 3, and the ends of the rotating shafts of the two groups of rollers 8 that are away from each other are located on the side of the support roller 3 away from the winding roller 11, so that the brass strip can slide relative to the roller 8 when being pulled. At this time, the friction force between the two has two components, and the directions of the two components are respectively away from the direction in which the brass strip is pulled and toward the side in the length direction of the brass strip. Among them, the component away from the direction in which the brass strip is pulled can make the brass strip straightened along the length direction, and the component toward the side in the length direction of the brass strip can make the brass strip straightened along the width direction. The cooperation of the two forces can ensure that the brass strip is in a stretched state, so that it can be located between the heating components, so that both sides can be heated evenly, thereby improving the heating effect and annealing effect of the brass strip.

[0053] Through the above arrangement, when the brass strip is pulled, it can slide relative to the roller 8 and generate two components of force in the vertical direction. Under the action of the two components of force, the brass strip can maintain a straight state when being pulled, so that both sides of the brass strip can be evenly heated, thereby improving the annealing effect.

[0054] See also Figure 1-2 , Figure 6 The heating component is arranged on the base 1, and the heating component can isothermally heat both sides of the brass strip, and the distance between the heating component and the brass strip is adjustable. The heating component includes a second bracket 13 fixedly mounted on the base 1, and two slide grooves 1301 are symmetrically arranged on the second bracket 13. A slider 15 is slidably installed in the slide groove 1301, and the slider 15 is connected to a double-headed electric telescopic rod 14 arranged on the second bracket 13; two groups of parallel flame spraying devices 16 are installed on the two groups of sliders 15, and the distance between the brass strip and the two groups of flame spraying devices 16 is the same when the brass strip is pulled.

[0055] Since the brass strip can be stretched straight during traction, the brass strip can be located between the two groups of flame spraying devices 16 in the initial state. At this time, when the flame spraying device 16 sprays flames, the distance between the flame and both sides of the brass strip can be made consistent, so that both sides of the brass strip are heated to the same degree, thereby improving the annealing effect.

[0056] However, the thickness specifications of brass strips often deviate according to customer needs. Specifically, the thickness range of brass strips is between 0.01mm and 2.0mm. Different heating degrees are required for different thicknesses. If the heating degrees are the same, the thinner brass strips may be overheated and melted.

[0057] In this embodiment, according to the thickness of the brass strip to be heated, the double-headed electric telescopic rod 14 is controlled to move, so that the two groups of flame spray devices 16 can move toward or away from the brass strip at equal distances and speeds. On the one hand, the distance between the flame and the brass strip can be changed to achieve different heating degrees. On the other hand, when the position of the flame spray device 16 is changed, its distance from the two sides of the brass strip is consistent, thereby ensuring that the two sides of the brass strip are heated uniformly, further improving the annealing effect.

[0058] Through the above arrangement, when brass strips of different thicknesses are annealed, the two groups of flame spray devices 16 can be moved toward or away from the brass strip at equal distances and speeds through the double-headed electric telescopic rod 14, so that on the one hand, the distance between the flame and the brass strip can be changed to achieve different heating degrees. On the other hand, when the position of the flame spray device 16 is changed, its distance from the two sides of the brass strip is consistent, thereby ensuring that the two sides of the brass strip are heated uniformly, further improving the annealing effect.

[0059] See also Figure 1 , Figure 7 to Figure 10 The regulating box 22 is detachably arranged on the base 1, and a plurality of gas delivery ports 2201 are equidistantly arranged at the bottom of the regulating box 22 along the length direction;

[0060] The blocking rods are provided in multiple groups and connected to the regulating box 22, and the blocking rods can change the conduction state of the gas delivery port 2201;

[0061] The abutment plate 24 is connected to the blocking rod, and the height of the abutment plate 24 gradually changes. When the abutment plate 24 located in the middle moves upward, it can cooperate with the abutment plate 24 adjacent thereto to drive the blocking rod to move in sequence, and can make the gas delivery port 2201 located at the side open in sequence. The blocking rod includes a blocking shaft 23 that is slidably arranged to penetrate the adjustment box 22, one end of the blocking shaft 23 is connected to the abutment plate 24, and the other end of the blocking shaft 23 is adapted to the gas delivery port 2201. When the abutment plate 24 moves away from the adjustment box 22, the blocking shaft 23 can make the gas delivery port 2201 open. Specifically, with the middle of the adjustment box 22 as the reference point and the side thereof as the forward direction, the height of the abutment plate 24 gradually increases in the forward direction.

[0062] The blocking shaft 23 is connected to the regulating box 22 via an elastic structure, and the elastic structure includes a first limiting ring 2301 and a second limiting ring 2302 arranged on the blocking shaft 23. A cylindrical spring 25 is also sleeved on the blocking shaft 23, and one end of the cylindrical spring 25 is connected to the second limiting ring 2302, and the other end of the cylindrical spring 25 is connected to the inner wall of the regulating box 22. When the first limiting ring 2301 abuts against the upper surface of the regulating box 22, the blocking shaft 23 can block the corresponding gas delivery port 2201.

[0063] The second bracket 13 is also provided with a second electric telescopic rod 17, and a transverse member 19 is connected to the action end of the second electric telescopic rod 17, and the transverse member 19 can slide in a guide member 18 provided on the side of the adjustment box 22. It is worth noting that the first electric telescopic rod 4 and the second electric telescopic rod 17 can move synchronously;

[0064] A connecting plate 21 is connected between the two groups of blocking shafts 23 located in the middle, and a support rod 20 is rotatably mounted on the connecting plate 21 . One end of the support rod 20 away from the connecting plate 21 is rotatably connected to the transverse member 19 .

[0065] When the width of the brass strip is narrow, the two groups of transverse frames 6 are in a state of being close to each other, and at the same time, the sealing shaft 23 can seal the gas delivery port 2201 that matches it. At this time, only the gas delivery port 2201 located in the middle of the adjustment box 22 is in a conductive state. At this time, the anti-oxidation gas entering the adjustment box 22 can be evenly sprayed onto the heated brass strip, thereby preventing the brass strip from oxidizing after being heated. At the same time, since the spray width of the anti-oxidation gas is quite large, the waste of the anti-oxidation gas is reduced.

[0066] When the brass strip with a wider width is annealed, the first electric telescopic rod 4 and the second electric telescopic rod 17 will move synchronously. At this time, the two rollers 8 will move away from each other so that the rollers 8 can be at the edge of the brass strip. At the same time, the cross piece 19 can move under the drive of the second electric telescopic rod 17, and the supporting rod 20 is used to move the connecting plate 21 upward. At this time, the two blocking shafts 23 connected to the connecting plate 21 can move upward, so that the gas delivery ports 2201 on both sides of the originally connected gas delivery ports 2201 are connected again. At this time, the width range of the anti-oxidation gas ejected from the connected gas delivery ports 2201 will be increased and matched with the width of the brass strip.

[0067] Furthermore, when the cross-piece 19 continues to move, the connecting plate 21 can continue to move upward. At this time, the abutment plate 24 on the blocking shaft 23 connected to the connecting plate 21 will continue to move upward, and when abutting against the abutment plate 24 on the adjacent blocking shaft 23, it can drive the adjacent abutment plate 24 to move upward, so that one of the gas delivery ports 2201 on both sides of the originally connected gas delivery port 2201 is connected again, further increasing the width range of the anti-oxidation gas ejected from the connected gas delivery port 2201.

[0068] When the link plate 21 is reset, the blocking shaft 23 can be reset under the driving of the columnar spring 25 .

[0069] Through the above arrangement, when the second electric telescopic rod 17 is in motion, it can drive the connecting plate 21 to move, and under the action of the two adjacent abutment plates 24, the gas delivery ports 2201 are connected one by one in sequence, thereby increasing the width range that the anti-oxidation gas can act on and matching it with the width of the brass strip. On the one hand, it can prevent the width range that the anti-oxidation gas can act on from being lower than the width of the brass strip, causing oxidation at the edge of the brass strip; on the other hand, it can prevent the width range that the anti-oxidation gas can act on from being higher than the width of the brass strip, causing waste of the anti-oxidation gas.
