DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention. It can be understood that some technical means of the various embodiments described herein can be replaced or combined with each other without conflict.

[0030] In the description of the present invention, if there are terms such as "first", "second", etc., they are only used to distinguish the objects described, and do not have any order or technical meaning. Therefore, the objects defined as "first", "second", etc. may explicitly or implicitly include one or more of the objects. In addition, "one" or "a" and similar words do not indicate a quantity limitation, but indicate the existence of at least one, and "multiple" means not less than two.

[0031] In the description of the present specification, reference to "one embodiment" or "some embodiments" etc. means that one or more embodiments of the present invention include a specific feature, structure or characteristic described in conjunction with the embodiment. Therefore, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0032] The invention provides a cutting device for heavy-weight alloy bars, which is used to improve the efficiency, reliability and stability of heavy-weight alloy bar cutting operations.

[0033] Reference Figures 1 to 4 In some embodiments, the cutting device for heavy alloy bars includes a receiving platform 10 and a positioning and conveying mechanism 20 and a cutting mechanism 30 disposed on the receiving platform 10. The positioning and conveying mechanism 20 is used to effectively fix the alloy bars during the cutting operation and automatically convey the alloy bars before and after the cutting operation, and the cutting mechanism 30 is used to effectively and accurately cut the alloy bars.

[0034] Specifically, refer to Figure 1 and Figure 2 A movable groove 11 extending along the conveying direction X is provided on the receiving platform 10, a plurality of extrusion chambers 12 are provided in the movable groove 11, a supporting assembly 13 is provided in the extrusion chamber 12, and the supporting assembly 13 includes a receiving seat 131, an ejection spring 132 and a ball 133. The receiving seat 131 is movably installed in the extrusion chamber 12, the ejection spring 132 is provided below the receiving seat 131, and the ball 133 is rotatably provided on the receiving seat 131.

[0035] Among them, refer to Figure 1 , the conveying direction X can correspond to the length direction and the front-back direction of the receiving platform 10. When the alloy bar is fed into the moving groove 11, the ball 133 moves downward due to the gravity of the alloy bar, driving the receiving seat 131 to move downward in the corresponding extrusion cavity 12, so that the corresponding ejection spring 132 is compressed; when the alloy bar moves out of the moving groove 11, the ejection spring 132 is no longer compressed, and the elastic force of the ejection spring 132 causes the receiving seat 131 and the ball 133 to move upward. It should be noted that in order to reduce the difficulty of conveying the alloy bar, the spring 132 adopts a high-elasticity spring product, so that after the alloy bar enters the moving groove 11, the ball 133 can still protrude from the extrusion cavity 12. In the process of the alloy bar moving along the conveying direction X, the ball 133 can rotate on the receiving seat 131, and there is rolling friction between the ball 133 and the alloy bar, which can reduce the overall movement difficulty of the alloy bar and avoid the inconvenience of the overall sliding of the alloy bar. At the same time, when the ball 133 supports the alloy rod, the ejection spring 132 can play a buffering role, reduce the impact force between the alloy rod and the ball 133, and improve the stability and reliability of the device.

[0036] Reference Figure 1 , Figure 3 and Figure 4The positioning conveying mechanism 20 includes a mounting frame 21, a conveying seat 22 and a conveying assembly 23. The mounting frame 21 is inverted U-shaped and straddles the top of the moving groove 11. The conveying seat 22 is movably arranged on the inner side of the mounting frame 21 in the vertical direction. The conveying assembly 23 is arranged on the bottom side of the conveying seat 22 and corresponds to the moving groove 11. The conveying assembly 23 includes a fixed plate 231, a conveying shaft 232, a conveying belt 233 and a rotating motor. There are two fixed plates 231, and the two fixed plates 231 are symmetrically arranged on the bottom side of the conveying seat 22; there are multiple conveying shafts 232, and the multiple conveying shafts 232 are rotatably arranged between the two fixed plates 231, and the central axis of the conveying shaft 232 is perpendicular to the conveying direction X. The conveying belt 233 is sleeved on the multiple conveying shafts 232; the rotating motor (not shown in the figure) is arranged on the side of one of the fixed plates 231, and the rotating motor is connected to at least one conveying shaft 232. The rotating motor can drive the corresponding conveying shaft 232 to rotate, and the conveying shaft 232 can drive the conveying belt 233 to rotate, and then drive the remaining conveying shafts 232 to rotate. Furthermore, an encoder is installed on the rotating motor, and the encoder can accurately measure the rotation speed and number of revolutions of the rotating motor, so as to feedback the distance that the conveying belt 233 drives the alloy bar to move, thereby improving the positioning accuracy of the alloy bar.

[0037] The cutting mechanism 30 includes a fixed frame 31, a cutting frame 32, a cutting wheel 33 and a driving member 34. The fixed frame 31 is in an inverted U shape. The cutting frame 32 can be movably arranged on the inner side of the fixed frame 31 in the vertical direction. The cutting wheel 33 can be rotatably arranged on the cutting frame 32. A dust suction chamber 14 is arranged on the receiving platform 10 corresponding to the cutting wheel 33. The driving member 34 is arranged on the fixed frame 31, and the driving member 34 is connected to the cutting frame 32. The driving member 34 is used to drive the cutting frame 32 to move in the vertical direction. Among them, the driving member 34 can adopt products such as screw guide rails, cylinders, and electric push rods in the prior art. During the cutting operation, the alloy rod moves to a specified position below the cutting wheel 33, and the driving member 34 can drive the cutting frame 32 and the cutting wheel 33 to move downward. The cutting wheel 33 rotates at high speed to cut the alloy rod, which can maintain extremely high cutting accuracy and stability, ensure a smooth cutting surface, and reduce material waste.

[0038] During application, the alloy rod is placed in the movable groove 11, and when the conveying seat 22 descends to the point where the conveyor belt 233 fits the top of the alloy rod, the ball 133 can still rotate and the alloy rod can move. At this time, the rotating motor is started, and the rotating motor drives the corresponding conveying shaft 232 to rotate, and the conveying shaft 232 drives the conveyor belt 233 to rotate, thereby driving the alloy rod to move along the conveying direction X to the set position; when the alloy rod moves to the set position, the conveying seat 22 continues to descend, so that the conveying assembly 23 presses the alloy rod, and the alloy rod presses the ball 133 and retracts the ball 133 into the corresponding extrusion cavity 12. At this time, the alloy rod is in a fixed state, thereby ensuring that the alloy rod will not move or slip during the cutting state.

[0039] In the cutting device for heavy alloy bars of the present invention, the supporting assembly 13 and the positioning and conveying mechanism 20 cooperate to realize the automatic feeding function, reduce the difficulty of work, improve work efficiency, and solve the problem that the overall weight and volume of the alloy bars are large and it is not convenient to move the whole before and after cutting; during the cutting operation, the conveying assembly 23 can effectively press the alloy bars to ensure that the alloy bars will not move when cutting, etc., and improve the positioning accuracy and cutting quality. The positioning and conveying mechanism 20 can realize the functions of pressing the bars and conveying the bars, and achieve the effect of "one machine for two uses", thereby effectively improving work efficiency and reducing the cost of use.

[0040] In some embodiments, the ball 133 is made of tungsten carbide, or the surface of the ball 133 is covered with a tungsten carbide coating, so that the ball 133 has high hardness and wear resistance, and reduces the friction coefficient of the ball 133, reducing the friction resistance between the alloy rod and the ball 133, thereby reducing energy consumption during automatic feeding.

[0041] In some preferred embodiments, an adjusting assembly 24 is disposed on the mounting frame 21 , and a sliding block 221 is disposed on the conveying seat 22 . The sliding block 221 cooperates with the adjusting assembly 24 to realize the movement of the conveying seat 22 in the vertical direction.

[0042] Specifically, the adjustment assembly 24 includes a screw rod 241, and the inner sides of both sides of the mounting frame 21 are respectively provided with limit grooves 211 extending in the vertical direction. There are two screw rods 241, and the two screw rods 241 are rotatably arranged in the limit grooves 211 on both sides. Slide blocks 221 are respectively arranged on both sides of the conveying seat 22, and the slide blocks 221 are sleeved on the corresponding screw rods 241. The slide blocks 221 are threadedly matched with the screw rods 241. When the screw rod 241 rotates, the slide blocks 221 can move up and down along the screw rod 241, thereby driving the conveying seat 22 to move up and down, and then adjusting the height of the conveying assembly 23.

[0043] Furthermore, the adjustment component 24 also includes a groove wheel 242, a transmission belt 243 and a servo motor (not shown in the figure). There are two groove wheels 242, and the two groove wheels 242 are coaxially connected to the screw rods 241 on both sides respectively. The transmission belt 243 is sleeved on the two groove wheels 242, and the servo motor drives and connects one of the groove wheels 242.

[0044] In application, the servo motor drives the corresponding groove wheel 242 to rotate, and the groove wheel 242 then drives another groove wheel 242 to rotate through the transmission belt 243. The two groove wheels 242 can respectively drive the screw rods 241 on both sides to rotate, and then drive the sliders 221 on both sides to move up and down to adjust the height of the conveying assembly 23.

[0045] In some embodiments, at least two groups of positioning and conveying mechanisms 20 are provided, and at least two groups of positioning and conveying mechanisms 20 are spaced apart in front of the cutting mechanism 30. At least two groups of positioning and conveying mechanisms 20 can effectively position and convey at least two locations of the alloy bar, thereby improving work efficiency.

[0046] Reference Figure 5 In some embodiments, the conveyor belt 233 is a three-layer composite structure, and the conveyor belt 233 includes a base layer 2331, an intermediate reinforcement layer 2332 and a surface layer 2333 arranged in sequence. The layers are compounded by a hot pressing bonding process, and the bonding temperature is 155-165°C, the pressure is 0.7-0.9MPa, and the time is 13-18min. Among them, the base layer 2331 is made of polyurethane and aramid composite materials, which can ensure high-strength flexible support, effectively withstand dynamic impact loads, and can effectively absorb vibration energy during transportation and reduce equipment noise. The tensile strength of the base layer 2331 is ≥45MPa, and the elongation at break is 380-420%. The intermediate reinforcement layer 2332 is made of silicon carbide whisker material, which can provide ultra-high modulus support, enhance the fracture toughness of the conveyor belt 233, and optimize the dynamic bearing capacity. The surface layer 2333 is used for contacting with the alloy rods. The surface layer 2333 is made of methyl vinyl silicone rubber composite material, which has wide temperature threshold stability, high wear resistance, high gripping ability, and low maintenance cost. It can increase the friction between the alloy rods and avoid slipping of the rods, thereby realizing efficient transportation of the rods.

The position sensors 15 may be proximity position sensors and other products in the prior art, and the plurality of position sensors 15 may be arranged along the conveying direction X.

Furthermore, there are four pressure sensors 235, which are respectively disposed at the four corners of the mounting platform 234. In application, when the alloy bar is compressed, each pressure sensor 235 can accurately and in real time monitor the pressure value data of each supporting point. At the same time, the four corners are arranged to form a symmetrical support system, which can evenly transfer the load to the mounting platform 234, effectively reduce the risk of local stress concentration, and improve the overall structural stability of the equipment.

[0049] In some embodiments, the substrate of the cutting wheel 33 is made of cemented carbide and the surface is provided with a diamond coating, thereby significantly improving the service life of the cutting wheel 33 and making it more suitable for cutting operations of heavy alloy rods.

[0050] Reference Figure 2 In some preferred embodiments, a filter screen 16 is provided in the dust suction chamber 14. Furthermore, a suction pipe 17 is provided on the side of the dust suction chamber 14, and the suction pipe 17 is connected to the dust suction chamber 14. The filter screen 16 can assist in receiving large-sized impurities, and in subsequent work, the suction pipe 17 can be connected to a negative pressure dust suction pump, thereby assisting in adsorbing the air with impurities generated by cutting to improve cleanliness.

[0053] The control method of the above-mentioned cutting device for heavy-weight alloy bars is as follows: the alloy bars are fed into the moving groove 11, and the servo motor drives the corresponding groove wheel 242 to rotate, and the groove wheel 242 then drives another groove wheel 242 to rotate through the transmission belt 243, and the two groove wheels 242 can respectively drive the screw rods 241 on both sides to rotate, and then drive the sliders 221 on both sides to move downward, so that the conveying assembly 23 fits the top of the alloy bar; start the rotating motor, and the rotating motor drives the corresponding conveying shaft 232 to rotate, and the conveying shaft 232 drives the conveying belt 233 to rotate, and then drives the alloy bar to move along the conveying direction X to the set position; thereafter, the rotating motor stops, and the conveying seat 22 continues to descend, so that the conveying assembly 23 presses the alloy bar, and at this time, the driving member 34 drives the cutting frame 32 and the cutting wheel 33 to move downward, and the cutting wheel 33 rotates at high speed to cut the alloy bar. After the cutting is completed, the servo motor drives the conveying seat 22 to move upward, so that the conveying assembly 23 fits the alloy bar but does not press the alloy bar, and the rotary motor drives the corresponding conveying shaft 232 to rotate, and the conveying shaft 232 drives the conveying belt 233 to rotate, thereby driving the alloy bar to move to the set position along the conveying direction X, and so on, to achieve automatic feeding and cutting operations.
