Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a chamfering machine. Background Technology

[0002] In the field of metal processing, metal strip is a commonly used processing raw material. The edge quality of the metal strip has an important impact on subsequent processing and product performance. Chamfering the edges of the metal strip can not only remove burrs generated during processing and reduce stress concentration, but also improve the assembly performance and appearance quality of the metal strip.

[0003] Currently, most common methods for chamfering metal strips employ a split structure: a fixed guide wheel at the front end provides rough positioning of the strip, followed by simultaneous cutting of both sides of the edge by a pair of rotary milling cutters with fixed angles. However, during the cutting process of the metal strip edges, the use of rotary milling cutters applies additional tangential force to the metal strip, causing displacement and easily leading to chamfering dimension deviations or excessive cutting, resulting in unstable chamfering quality. Therefore, a chamfering machine is urgently needed to solve the above problems. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a chamfering machine, which solves the technical problem that when existing chamfering equipment processes metal strips, the metal strips are prone to displacement, resulting in large deviations in chamfering dimensions and unstable chamfering quality.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A chamfering machine for chamfering the edges of metal strips, comprising:

[0007] The mounting plate, corresponding to the feeding direction of the metal strip, is provided with the following in sequence:

[0008] A feeding guide mechanism is used to initially guide the metal strip;

[0009] A cutting assembly, comprising: a pair of cutting blades arranged opposite each other in the Y direction, wherein the ends of the cutting blades are provided with grooves, the inclination angle of the groove wall corresponds to the chamfer angle, and the pair of grooves are respectively used to accommodate the two sides of the metal strip;

[0010] A scraper assembly, comprising: a pair of scrapers, the pair of scrapers being used to smooth the cutting surface of a metal strip after it has been cut by a cutting blade, wherein the contact angle between the cutting edge of the scraper and the cutting surface is adjustable;

[0011] Z-direction limiting component, the Z-direction limiting component is used to limit the metal strip in the Z direction.

[0012] Based on the above structure, the principle of the chamfering machine is as follows: First, the metal strip is placed on the feeding guide mechanism, which initially guides the metal strip to enter the chamfering machine along the feeding direction, reducing the deviation of the metal strip and improving the accuracy and stability of the processing. The metal strip enters the cutting assembly, with both sides of the metal strip located within the groove. Since the inclination angle of the groove wall corresponds to the chamfering angle, the groove wall cuts the two sides of the metal strip during feeding, achieving chamfering. The metal strip enters the scraper assembly. By adjusting the contact angle between the scraper blade and the cutting surface, the scraping effect can be optimized according to different cutting conditions and processing requirements, making the cutting surface smoother and flatter, improving processing quality, reducing surface roughness, and avoiding burrs or unevenness. During processing, the Z-direction limiting assembly limits the metal strip in the Z-direction, ensuring that the metal strip does not shift in the Z-direction during processing, guaranteeing processing accuracy and stability.

[0013] Furthermore, in a chamfering machine of this application, the feeding guide mechanism includes: a supporting roller and a pair of guide wheels. The supporting roller is rotatably mounted on the feeding end of the mounting plate. The pair of guide wheels are located on the front side of the supporting roller in the feeding direction. The pair of guide wheels are movable and adjustable in the Y direction. When the metal strip passes through the feeding guide mechanism, the metal strip is located between the pair of guide wheels. The two edges of the metal strip respectively contact and limit the arc-shaped guide surfaces of the pair of guide wheels. The arc-shaped side of the supporting roller is used to support the bottom surface of the metal strip. As a preferred embodiment of this application, a chamfering machine includes a support roller that provides support for the metal strip, maintaining a certain height and level during feeding to prevent the metal strip from sagging or swaying due to its own weight, ensuring that the metal strip can smoothly enter the subsequent processing area. A pair of guide wheels can limit the position of the metal strip in the Y direction, ensuring that the metal strip moves along a predetermined path and preventing the strip from deviating to the left or right during feeding. The pair of guide wheels are movable in the Y direction. This design allows the feeding guide mechanism to adapt to metal strips of different widths. By adjusting the distance between the pair of guide wheels, the feeding guide requirements of metal strips of different widths can be met, improving the versatility and flexibility of the chamfering machine.

[0014] Furthermore, in a chamfering machine of this application, the cutting assembly further includes: a first base plate and a pair of first mounting seats. The first base plate is mounted on a mounting plate, and the pair of first mounting seats are spaced apart on the first base plate in the Y direction. The first mounting seats are movable and adjustable in the Y direction. A pair of cutting blades are detachably mounted on the pair of first mounting seats. Corresponding to the feeding direction of the metal strip, the first mounting seat is provided with a first guide roller. The first guide roller is located at the front end of the cutting blade. When the metal strip is located between the pair of first guide rollers, the two edges of the metal strip respectively contact and limit the arcuate surfaces of the pair of first guide rollers. As a preferred embodiment of this application, a chamfering machine of this application has a pair of cutting blades mounted at intervals in the Y direction on a first base plate, and these blades can be moved and adjusted in the Y direction. This design allows the distance between the pair of cutting blades to be flexibly adjusted according to the width of the metal strip, thereby adapting to metal strips of different specifications, improving the versatility and flexibility of the cutting components. Furthermore, the cutting blades are detachably mounted on the first mounting base, facilitating the replacement and maintenance of the cutting blades. When the cutting blades are worn or damaged, they can be replaced in a timely manner to ensure processing quality. A pair of first guide rollers guide the metal strip, ensuring that the metal strip is in a preset position before entering the cutting blades for chamfering, preventing the strip from shifting or shaking during the feeding process, thereby improving the accuracy and consistency of the chamfering process.

[0015] Furthermore, in one chamfering machine of this application, a cooling assembly is provided on the first base plate, the cooling assembly being used to spray coolant onto the cutting tool. As a preferred embodiment of this application, in the process of cutting metal strip, heat is generated between the cutting tool and the strip. The cooling assembly sprays coolant to reduce the temperature of the cutting tool, thereby reducing thermal deformation and wear of the cutting tool and improving its cutting performance and durability.

[0016] Furthermore, in a chamfering machine of this application, the cooling assembly includes: a base, a liquid inlet on the base, and a universal bamboo-joint tube, the liquid inlet being connected to the universal bamboo-joint tube, and a nozzle being provided at the end of the universal bamboo-joint tube away from the base. As a preferred embodiment of this application, the universal bamboo-joint tube in the chamfering machine of this application has the characteristic of being flexible and adjustable, allowing the nozzle to be adjusted according to the position and angle of the cutting tool, ensuring that the coolant is accurately sprayed onto the part requiring cooling, thereby improving the adaptability and flexibility of the cooling system.

[0017] Furthermore, in a chamfering machine of this application, the scraper assembly further includes: a second base plate, the second base plate being mounted on a mounting plate, the second base plate having a pair of second mounting seats that are movably adjustable in the Y direction, a pair of scrapers being disposed between the pair of second mounting seats, the pair of scrapers being detachably mounted on the pair of second mounting seats respectively, and a pair of second guide rollers being disposed between the pair of second mounting seats, the pair of second guide rollers being respectively mounted on the pair of second mounting seats, the second guide rollers being located at the rear end of the scrapers corresponding to the feeding direction of the metal strip. As a preferred embodiment of this application, a chamfering machine includes a pair of scrapers that are movable and adjustable in the Y direction. This allows the distance between the scrapers to be flexibly adjusted according to the width of the metal strip and processing requirements, adapting to the scraping of metal strips of different specifications and improving the versatility of the scraper assembly. The detachable installation method facilitates the replacement and maintenance of the scrapers. When the scrapers are worn or damaged, they can be replaced in a timely manner to ensure the scraping effect and processing quality. When the metal strip passes through the scraper assembly, the second guide roller further guides and limits the metal strip, ensuring that the metal strip continues to move along the predetermined path after being scraped by the scrapers. This prevents the metal strip from deviating or shaking during the scraping process, ensuring the accuracy of the scraping process. It also provides support for the scraped strip, keeping it in a stable position for subsequent processing or conveying.

[0018] Furthermore, in a chamfering machine of this application, guide mechanisms are provided between the feeding guide mechanism and the cutting assembly, between the cutting assembly and the scraper assembly, and between the scraper assembly and the Z-direction limiting assembly. The guide mechanism includes: a third base plate, which is mounted on a mounting plate. The third base plate is provided with a pair of third mounting seats that are movable and adjustable in the Y direction. Each pair of third mounting seats is provided with a set of third guide rollers. The set of third guide rollers is spaced apart along the feeding direction of the metal strip. When the metal strip is located on the guide mechanism, the two edges of the metal strip respectively contact and limit the arcuate surfaces of the two sets of third guide rollers. As a preferred embodiment of this application, a chamfering machine of this application, when the metal strip is located on the guiding mechanism, has its two edges respectively contacting and limiting the arc-shaped surfaces of a corresponding set of guide rollers. This allows for accurate guidance of the metal strip from both sides during the feeding process, ensuring that the metal strip always moves along a predetermined path and preventing it from shifting to the left or right. This guarantees the positional accuracy of the metal strip during transmission between the feeding guiding mechanism, the cutting assembly, the scraper assembly, and the Z-axis limiting assembly, thereby improving the accuracy and consistency of the entire processing process.

[0019] Furthermore, in a chamfering machine of this application, the Z-direction limiting component includes: a fourth base plate and a set of Z-direction pressure heads. The fourth base plate is mounted on a mounting plate, and the set of Z-direction pressure heads are spaced apart along the Y direction. The Z-direction pressure heads are positioned directly opposite the fourth base plate and are movable and adjustable in the Z direction. As a preferred embodiment of this application, in a chamfering machine, the distance between the set of Z-direction pressure heads and the fourth base plate can be flexibly adjusted according to the thickness of the metal strip and processing requirements, thereby limiting metal strips of different thicknesses in the Z direction and ensuring that the metal strip does not jump up and down or shift in the Z direction during processing, thus guaranteeing processing accuracy and stability.

[0020] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0021] The purpose of this invention is to provide a chamfering machine that, by incorporating an adjustable feeding guide mechanism, a cutting assembly, a scraper assembly, and a Z-axis limiting assembly, can adapt to metal strips of varying widths and thicknesses, ensuring the stability and accuracy of the metal strips during processing. Precise chamfering is achieved through a groove at the end of the cutting blade corresponding to the chamfering angle, and an adjustable-angle scraper smooths the cutting surface, improving the surface quality. Simultaneously, a cooling assembly cools the cutting blade, reducing tool wear, thereby improving the chamfering machine's processing accuracy, quality, and service life, and enhancing the equipment's versatility and flexibility.

Detailed Implementation

[0028] like Figure 1 , 3 As shown in Figure 4, a chamfering machine is used to chamfer the edges of metal strips, comprising:

[0029] Mounting plate 1, corresponding to the feeding direction of the metal strip, is provided with the following in sequence:

[0030] The feeding guide mechanism 2 is used to initially guide the metal strip.

[0031] The cutting assembly 3 includes: a pair of cutting blades 31 arranged opposite each other in the Y direction, the ends of the cutting blades 31 being provided with receiving grooves 310, the inclination angle of the groove wall of the receiving groove 310 corresponding to the chamfer angle, and the pair of receiving grooves 310 being used to accommodate the two sides of the metal strip respectively.

[0034] Based on the above structure, the principle of the chamfering machine is as follows: First, the metal strip is placed on the feeding guide mechanism 2, which initially guides the metal strip to enter the chamfering machine along the feeding direction, reducing the deviation of the metal strip and improving the accuracy and stability of the processing. The metal strip enters the cutting assembly 3, with both sides of the metal strip located in the groove 310. Since the inclination angle of the groove wall of the groove 310 corresponds to the chamfering angle, the groove wall of the groove 310 cuts the two sides of the metal strip during the feeding process, achieving chamfering. The metal strip enters the scraper assembly 4. By adjusting the contact angle between the cutting edge of the scraper 41 and the cutting surface, the scraping effect can be optimized according to different cutting conditions and processing requirements, making the cutting surface smoother and flatter, improving processing quality, reducing surface roughness, and avoiding burrs or unevenness. During the processing, the Z-direction limiting assembly 5 limits the metal strip in the Z-direction, ensuring that the metal strip will not shift in the Z-direction during processing, thus guaranteeing the accuracy and stability of the processing.

[0035] In this embodiment, the feeding guide mechanism 2 includes: a support roller 21 and a pair of guide wheels 22. The support roller 21 is rotatably mounted on the feeding end of the mounting plate 1. The pair of guide wheels 22 are located on the front side of the support roller 21 in the feeding direction. The pair of guide wheels 22 are movable and adjustable in the Y direction. When the metal strip passes through the feeding guide mechanism 2, the metal strip is located between the pair of guide wheels 22. The two edges of the metal strip are respectively contacted and limited by the arc-shaped guide surfaces of the pair of guide wheels 22. The arc-shaped side of the support roller 21 is used to support the bottom surface of the metal strip. The support roller 21 provides support for the metal strip, maintaining its height and level during feeding and preventing it from sagging or swaying due to its own weight. This ensures the metal strip enters the subsequent processing area smoothly. A pair of guide wheels 22 restrict the position of the metal strip in the Y direction, ensuring it moves along a predetermined path and preventing lateral deviation during feeding. The guide wheels 22 are movable in the Y direction, allowing the feeding guide mechanism 2 to adapt to metal strips of different widths. By adjusting the distance between the guide wheels 22, the feeding guide requirements for metal strips of different widths can be met, improving the versatility and flexibility of the chamfering machine. The support roller 21 is rotatably mounted on the feeding end of the mounting plate 1 via bearings (not shown). Its axis is perpendicular to the feeding direction of the metal strip and rotates synchronously with the movement of the metal strip.

The pair of cutting blades 31 are detachably mounted on the pair of first mounting seats 33. Corresponding to the feeding direction of the metal strip, the first mounting seat 33 is provided with a first guide roller 34. The first guide roller 34 is located at the front end of the cutting blade 31. When the metal strip is located between the pair of first guide rollers 34, the two edges of the metal strip are respectively contacted and limited by the arcuate surfaces of the pair of first guide rollers 34. A pair of cutting blades 31 are mounted at intervals on the first base plate 32 in the Y direction and can be adjusted in the Y direction. This design allows the distance between the pair of cutting blades 31 to be flexibly adjusted according to the width of the metal strip, thereby adapting to metal strips of different specifications and improving the versatility and flexibility of the cutting assembly 3. Furthermore, the cutting blades 31 are detachably mounted on the first mounting base 33, facilitating the replacement and maintenance of the cutting blades 31. When the cutting blades 31 are worn or damaged, they can be replaced promptly to ensure processing quality. A pair of first guide rollers 34 guide the metal strip, ensuring that the metal strip is in a preset position before entering the cutting blades 31 for chamfering, preventing the strip from shifting or shaking during feeding, thereby improving the accuracy and consistency of the chamfering process. The first mounting base 33 is adjustable in the Y direction via a screw and nut transmission adjustment mechanism (not shown); the cutting blades 31 are detachably mounted on the first mounting base 33 via screws (not shown).

When the metal strip passes through the scraper assembly 4, the second guide roller 44 further guides and limits the metal strip, ensuring that it continues to move along the predetermined path after being scraped by the scrapers 41. This prevents the metal strip from deviating or shaking during scraping, ensuring the accuracy of the scraping process. It also provides support for the scraped strip, keeping it stable for subsequent processing or conveying.
