Description

Technical Field

[0001] The present invention relates to the technical field of cutting machines, and in particular to a profile cutting machine capable of cutting arc chamfers. Background Art

[0002] Using profiles to make doors and windows is a relatively common method. During production and assembly, the ends of the profiles are cut into bevels. When the bevels of two profiles are aligned with each other, the two profiles form a 90° included angle state to achieve splicing. Currently, a cutting machine is usually used to cut the profiles. When cutting the profiles, due to poor pressing stability of the profiles during the cutting process, the profiles may move slightly during the cutting process, resulting in low cutting accuracy. Moreover, the cut profiles need to be unloaded from the cutting machine and then loaded into a chamfering machine for chamfering treatment, resulting in low processing efficiency.

Therefore, it should not be construed as a limitation to the present invention. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features, which are used to distinguish and describe features, without order or importance.

[0046] In the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0047] As Figures 1 to 3 shown, a profile cutting machine capable of cutting arc chamfers includes a frame 1, and a cutting mechanism 2, a material pressing mechanism 3, and a chamfering mechanism 4 provided on the frame 1. The top of the frame 1 is symmetrically provided with workbench plates 11 on the left and right. The two workbench plates 11 are spaced apart, and a cutting opening 111 is formed between the two workbench plates 11. A reference seat 112 is provided on the front side of the workbench plate 11. The workbench plate 11 is used for placing the profile 5;

[0048] The cutting mechanism 2 includes a first cutting assembly 21 and a second cutting assembly 22. The first cutting assembly 21 and the second cutting assembly 22 are respectively provided corresponding to one of the workbench plates 11, and the first cutting assembly 21 and the second cutting assembly 22 are symmetrically arranged on the rear of the corresponding workbench plate 11 on the left and right. A cutting angle A is formed between the cutting ends of the first cutting assembly 21 and the second cutting assembly 22. The cutting angle A is greater than 0° and less than 180°. The first cutting assembly 21 and the second cutting assembly 22 are respectively used for cutting the profile 5;

[0049] The material pressing mechanism 3 includes a horizontal material pressing assembly 31. The horizontal material pressing assembly 31 is inclinedly arranged on the upper surface of the workbench plate 11. The material pressing end of the horizontal material pressing assembly 31 is arranged towards the side of the cutting opening 111. The horizontal material pressing assembly 31 is used for pushing the profile 5 until the profile 5 abuts against the reference seat 112;

[0050] The chamfering mechanism 4 is arranged at the front end of the frame 1. The working end of the chamfering mechanism 4 is arranged corresponding to the cutting opening 111. The chamfering mechanism 4 is used for chamfering the cut profile 5.

[0051] Before cutting, place the profile 5 on the two workbench plates 11, and then use the horizontal material pressing component 31 to push the profile 5 until it abuts against the reference seat 112, so as to fix the processing position of the profile 5. Since the material pressing end of the horizontal material pressing component 31 is arranged towards the side of the cutting opening 111, after the horizontal material pressing component 31 pushes the profile 5 until it abuts against the reference seat 112, the pressing point of the horizontal material pressing component 31 on the profile 5 can be closer to the position where the profile 5 needs to be cut, so as to ensure the stability of the pressing of the horizontal material pressing component 31 on the profile 5. After the profile 5 is stably pressed, by setting the cutting mechanism 2, the first cutting component 21 and the second cutting component 22 of the cutting mechanism 2 respectively cut the profile 5 placed on the workbench plate 11 into two halves. Since the profile 5 is stably pressed, the cutting accuracy is effectively guaranteed. After cutting, the chamfering mechanism 4 can be used to chamfer the cut profile 5. The chamfering mechanism 4 can chamfer the two cut profiles 5 respectively, without the need to unload the two cut profiles 5 and then use a chamfering machine for chamfering, and the processing efficiency is high.

[0052] The profile cutting machine capable of cutting circular chamfers can chamfer the cut profile 5, has high processing efficiency, and has high pressing stability for the profile 5 during the cutting process, ensuring the cutting accuracy, and solves the problems that the existing profile cutting machines cannot chamfer the cut profile 5, have low processing efficiency and low cutting accuracy.

[0053] As Figure 4 and Figure 5 shown, further illustrate that the structures of the first cutting component 21 and the second cutting component 22 are the same. The first cutting component 21 includes a cutting seat 211, a first guide rail 212, a first slider 213, a first driving device 214 and a cutting module 215;

[0054] The first guide rail 212 is arranged on the cutting seat 211 in the up and down direction. The first slider 213 is slidably arranged on the first guide rail 212. The cutting module 215 is connected to the first slider 213. The piston rod of the first driving device 214 is fixedly connected to the cutting module 215. The first driving device 214 drives the cutting module 215 to make a reciprocating up and down movement.

[0055] By setting the first guide rail 212, the first slider 213 and the first driving device 214, the first driving device 214 drives the cutting module 215 to perform a reciprocating up-and-down movement, realizing the up-and-down movement of the cutting module 215. In the initial state, the cutting module 215 is located above the workbench 11. When the profile 5 needs to be cut, the first driving device 214 drives the cutting module 215 to move downward to cut the profile 5 from top to bottom. After cutting, the first driving device 214 drives the cutting module 215 to move upward and reset. Since the cutting module 215 cuts from top to bottom and has its own gravity during cutting, the cutting force is large, and the cutting surface of the profile 5 can be a vertical surface, with high cutting efficiency and cutting accuracy. Specifically, the first driving device 214 is a cylinder, with a fast driving speed and high driving efficiency.

[0056] Specifically, the cutting module 215 includes a cutting blade 2151, a second driving device 2152, a first sliding seat 2153, a fixed seat 2154 and a fixed column 2155;

[0057] The first sliding seat 2153 is connected to the first slider 213. The first sliding seat 2153 is arranged in front of the cutting seat 211, and the fixed seat 2154 is arranged behind the cutting seat 211. A fixed column 2155 is fixedly connected between the first sliding seat 2153 and the fixed seat 2154;

[0058] The cutting blade 2151 is rotatably arranged on the first sliding seat 2153. The second driving device 2152 is fixedly arranged on the fixed seat 2154. The output end of the second driving device 2152 is in transmission connection with the cutting blade 2151. The second driving device 2152 drives the cutting blade 2151 to rotate, and the piston rod of the first driving device 214 is fixedly connected to the fixed seat 2154.

[0059] By setting the first sliding seat 2153, the fixing of the cutting blade 2151 is realized. By setting the fixing seat 2154, the fixing of the second driving device 2152 is realized. And since the fixing column 2155 is fixedly connected between the first sliding seat 2153 and the fixing seat 2154, the piston rod of the first driving device 214 is fixedly connected to the fixing seat 2154. The first driving device 214 drives the fixing seat 2154 to move up and down. The fixing seat 2154 drives the first sliding seat 2153 to slide up and down, realizing the reciprocating movement of the first driving device 214 driving the cutting module 215 to move up and down, and being able to ensure the driving stability of the second driving device 2152 for the cutting blade 2151. The second driving device 2152 drives the cutting blade 2151 to rotate to realize the cutting of the profile 5 by the cutting blade 2151. Specifically, a plurality of fixing columns 2155 are provided to ensure the connection stability between the first sliding seat 2153 and the fixing seat 2154. The second driving device 2152 is a motor with high driving stability.

[0060] Furthermore, the first driving devices 214 of the first cutting assembly 21 and the first driving devices 214 of the second cutting assembly 22 can operate independently or simultaneously to drive the corresponding cutting blades 2151 to move up and down, with strong processing flexibility.

[0061] Furthermore, the cutting module 215 further includes a rotating shaft 2156, a first pulley 2157, a second pulley 2158 and a belt;

[0062] The rotating shaft 2156 is rotatably arranged at the front end of the first sliding seat 2153. One end of the rotating shaft 2156 is fixedly connected to the cutting blade 2151, and the other end of the rotating shaft 2156 is fixedly connected to the first pulley 2157.

The belt passes through the first through hole 2159, the second through hole 2111 and the third through hole 2150 and is wound around the first pulley 2157 and the second pulley 2158;

[0064] The second driving device 2152 drives the second pulley 2158 to rotate, thereby driving the first pulley 2157 to rotate. The rotation of the first pulley 2157 drives the cutting blade 2151 to rotate.

[0065] By arranging the rotating shaft 2156, the first pulley 2157, the second pulley 2158 and the belt, the transmission connection between the output end of the second driving device 2152 and the cutting blade 2151 is realized. The output end of the second driving device 2152 drives the second pulley 2158 to rotate. Under the action of the belt, the first pulley 2157 is driven to rotate, and the rotation of the first pulley 2157 drives the cutting blade 2151 to rotate, with strong driving stability.

[0066] Specifically, the cutting blade 2151 is inclined, and the cutting blade 2151 is located above the cutting opening 111. The surface of the workbench 11 opposite to the cutting blade 2151 is an inclined surface 113. The cutting opening 111 is located in front of the inclined surface 113. A cutting angle A is formed between the cutting blade 2151 of the cutting module 215 of the first cutting assembly 21 and the cutting blade 2151 of the cutting module 215 of the second cutting assembly 22, and the cutting angle A is 90°.

[0067] By arranging the cutting blade 2151 to be inclined, the surface of the workbench 11 opposite to the cutting blade 2151 is an inclined surface 113. The workbench 11 can avoid and cooperate with the cutting blade 2151. The cutting angle A is 90°. After the cutting blades 2151 of the cutting modules 215 of the first cutting assembly 21 and the second cutting assembly 22 complete the cutting of the profile 5, the profile 5 can be cut into two parts, and the cutting surface is an inclined surface 113 with an inclination angle of 45°. As Figure 6 shown, when the 45° angles of two profiles are aligned with each other, the two profiles are in a state of forming a 90° angle with each other, which is convenient for splicing.

[0068] As Figure 7 shown, further illustrate that the chamfering mechanism 4 includes a third driving device 41, a second sliding seat 42, a fourth driving device 43, a third sliding seat 44, a fifth driving device 45, a fourth sliding seat 46 and a chamfering module 47;

[0069] The third driving device 41 is fixedly arranged on the front end face of the frame 1. The second sliding seat 42 is slidably arranged up and down on the front end face of the frame 1.

[0070] The fourth driving device 43 is fixedly arranged on the front end face of the frame 1. The third sliding seat 44 is slidably arranged back and forth on the upper surface of the second sliding seat 42. The piston rod of the fourth driving device 43 is fixedly connected to the third sliding seat 44. The fourth driving device 43 drives the third sliding seat 44 to perform a reciprocating motion of sliding back and forth.

[0071] The fifth driving device 45 is fixedly arranged on the third sliding seat 44. The fourth sliding seat 46 is slidably arranged left and right on the upper surface of the third sliding seat 44. The piston rod of the fifth driving device 45 is fixedly connected to the fourth sliding seat 46. The fifth driving device 45 drives the fourth sliding seat 46 to perform a reciprocating motion of sliding left and right.

[0072] The chamfering module 47 is arranged on the upper surface of the fourth sliding seat 46, and the working end of the chamfering module 47 is arranged corresponding to the cutting opening 111.

[0073] By arranging the third driving device 41, the second sliding seat 42, the fourth driving device 43, the third sliding seat 44, the fifth driving device 45 and the fourth sliding seat 46, the chamfering module 47 can be driven to move in three directions of up and down, back and forth, and left and right, so that the chamfering module 47 can respectively chamfer the two profiles 5 obtained by cutting. For example, the chamfering module 47 can first chamfer the profile 5 that has been cut on the left side, and then move to the right to chamfer the profile 5 that has been cut on the right side. When chamfering, the chamfering of the sharp corners of the cut profiles 5 can be realized through movements in different directions, and the chamfer can be a circular arc chamfer or a straight chamfer. As Figure 8 shown, after chamfering, Figure 8 (a) is a circular arc chamfer, Figure 8 (b) is a straight chamfer. Different chamfering treatments can be carried out according to the needs of the product. It only needs to control the movement of the chamfering module 47 in three directions through the third driving device 41, the fourth driving device 43 and the fifth driving device 45. The processing flexibility is high, and the chamfering of the two profiles 5 obtained by cutting can be completed simultaneously in one processing, and the processing efficiency is high.

[0074] Specifically, the third driving device 41, the fourth driving device 43 and the fifth driving device 45 are all cylinders, with fast driving speed and high driving efficiency.

[0075] Furthermore, the chamfering mechanism 4 further includes a second guide rail 481, a second slider, a third guide rail 482, a third slider 483, a fourth guide rail 484 and a fourth slider 485. The second guide rail 481 is arranged along the up and down direction on the front end face of the frame 1. The second slider is slidably arranged on the second guide rail 481, and the second sliding seat 42 is connected to the second slider;

[0076] The third guide rail 482 is arranged on the upper surface of the second sliding seat 42 in the front-back direction. The third slider 483 is slidably arranged on the third guide rail 482, and the third sliding seat 44 is connected to the third slider 483.

[0078] The second sliding seat 42, the third sliding seat 44, and the fourth sliding seat 46 respectively achieve the up-and-down sliding of the second sliding seat 42, the front-back sliding of the third sliding seat 44, and the left-right sliding of the fourth sliding seat 46 through the cooperation of the guide rail and the slider. The sliding stability is strong, thereby ensuring the movement stability of the chamfering module 47 and improving the chamfering accuracy.

[0079] Further explanation, the chamfering module 47 includes a chamfering tool 471 and a sixth driving device 472. The sixth driving device 472 is arranged on the fourth sliding seat 46. The output end of the sixth driving device 472 is fixedly connected to the chamfering tool 471. The sixth driving device 472 drives the chamfering tool 471 to rotate, and the chamfering tool 471 is arranged corresponding to the cutting opening 111.

[0080] By setting the sixth driving device 472, the sixth driving device 472 drives the chamfering tool 471 to rotate. While the chamfering tool 471 is rotating, the third driving device 41, the fourth driving device 43, and the fifth driving device 45 control the chamfering module 47 to move in three directions, thereby driving the chamfering tool 471 to enter the cutting opening 111 and chamfer the two cut profiles 5.

Specifically, the eighth driving device 322 can be a cylinder. In addition, the vertical material pressing assembly 32 is arranged close to the cutting opening 111, which can make the pressing point of the vertical material pressing assembly 32 on the profile 5 closer to the position where the profile 5 needs to be cut, and cooperate with the horizontal material pressing assembly 31 to further ensure the stability of pressing the profile 5.

[0088] Preferably, the horizontal material pressing assembly 31 and the vertical material pressing assembly 32 are symmetrically arranged on the two workbench plates 11 respectively;

[0089] The included angle B between the vertical plane where the material pressing rod 311 is located and the vertical plane where the reference seat 112 is located is 45°.

[0090] Specifically, one horizontal material pressing assembly 31 and one vertical material pressing assembly 32 are respectively arranged on the surfaces of the two workbench plates 11.
