Description

Technical Field

[0001] The present invention relates to the technical field of cutting devices, and specifically to a titanium alloy cutting device and its usage method. Background Art

[0002] Currently, in the process of cutting titanium alloy tubes in the existing technology, generally, both ends of the titanium alloy tube are fixed by chucks, and then the position of the cutting device is adjusted to cut the titanium alloy tube.

[0003] However, in the process of using this method, first, the fixing process of both ends of the titanium alloy tube is relatively cumbersome, and it takes a long time to ensure that the chucks can firmly hold the tube. This not only affects the overall production efficiency, but also, after the cutting operation is completed, the process of removing the titanium alloy tube from the chucks is relatively slow, which further prolongs the production cycle. More importantly, due to its unique physical properties, such as a low elastic modulus, titanium alloy is prone to bending deformation when subjected to external forces. During the cutting process, the titanium alloy tube deforms under the action of the cutting pressure, causing vibration during the cutting process, resulting in a decline in cutting quality, accelerating the wear of the cutting tool, thereby reducing the service life of the cutting tool. At the same time, the deformation directly affects the accuracy of the machined part after cutting, making it difficult for the product to meet the design requirements. In view of this, the present invention proposes a titanium alloy cutting device and its usage method. Summary of the Invention

[0008] In a further embodiment, the middle of the first straight rod or the second straight rod is hinged to a third straight rod. One end of the third straight rod away from the first straight rod or the second straight rod is hingedly installed on the outer wall of the electric cylinder.

[0009] In a further embodiment, the square plate is fixedly connected to a connecting plate through a vertical rod. A plurality of groups of hemispherical protrusions arranged at equal intervals are provided on the outer wall of the connecting plate.

[0010] In a further embodiment, an auxiliary blanking assembly is further provided in the machine body. The auxiliary blanking assembly includes a limiting block. The limiting block is fixed on a mounting frame. A round rod is penetrated and slidably arranged on the limiting block. A convex rod is arranged at one end of the round rod close to the hemispherical protrusion, and the convex rod and the round rod are elastically connected through a torsion spring. A U-shaped member is fixedly connected to the other end of the round rod away from the convex rod. The limiting block and the U-shaped member are elastically connected through a return spring. A sliding rod is fixedly connected to the surface of the U-shaped member. The sliding rod is slidably connected to a knocking rod.

[0011] In a further embodiment, the sliding rod is slidably connected in a straight groove of the knocking rod. The knocking rod is hinged to a support rod. The support rod is fixedly installed on the mounting frame. An elastic ball is fixedly connected to the end of the knocking rod away from the sliding rod.

[0012] In a further embodiment, a filter plate is arranged below the cutting mechanism, and a collection box is arranged below the filter plate; After the U-shaped member moves and resets in the direction of the hemispherical protrusion under the reset acting force of the return spring, at this time, the elastic ball is in contact with the upper surface of the filter plate.

[0013] In a further embodiment, the filter plate is a V-shaped filter plate with high sides and low middle.

[0014] The present invention also proposes a usage method of a titanium alloy cutting device, including the following steps: S1. Place the titanium alloy pipe on the three-jaw chuck for fixation. Start the lead screw motor, which drives the lead screw to rotate. Consequently, the sliding seat moves within the guide seat to adjust the position of the electric cylinder. After the position adjustment is completed, start the electric cylinder. The output end of the electric cylinder contracts, the fixing member drives the articulated rod to move, and the two T-shaped members drive the two cutting discs to move towards each other. At the same time, start the drive motor to complete the cutting of the titanium alloy pipe. S2. Start the main motor. The output shaft of the main motor drives the reducer to work. The output end of the reducer drives the three-jaw chuck to rotate at a reduced speed, and the auxiliary cutting disc cuts the titanium alloy pipe. S3. The output end of the electric cylinder contracts, the fixing member drives the square plate to move. Under the action of the third straight rod, the first straight rod and the second straight rod drive the receiving plate to move below the titanium alloy pipe to realize the receiving of the cut titanium alloy pipe. S4. Start the output end of the electric cylinder to extend, the fixing member drives the square plate to reset, the two T-shaped members drive the two cutting discs to move away from each other, and at the same time the receiving plate moves back to its original position. S5. During the reset movement of the square plate, the connecting plate and the hemispherical protrusion move away from the electric cylinder. The hemispherical protrusion presses the convex rod, and the convex rod drives the round rod and the U-shaped member to move, stretching the reset spring. The sliding rod slides in the straight groove of the knocking rod, and the knocking rod rotates around the hinge point of the support rod. The elastic ball moves away from the upper surface of the filter plate. After the hemispherical protrusion passes through the convex rod, the reset spring resets, and the elastic ball contacts the upper surface of the filter plate again. The filter plate vibrates, and the auxiliary waste chips pass through the filter plate and enter the collection box for collection.

[0015] The present invention provides a titanium alloy cutting device, which has the following beneficial effects: (1). By adopting a double cutting disc design, that is, the two T-shaped members drive the two cutting discs to move towards each other and apply cutting forces simultaneously, the titanium alloy cutting device effectively prevents the deformation of the titanium alloy pipe during cutting due to uneven force, thereby improving the cutting quality and part accuracy. At the same time, by driving the lead screw to rotate through the lead screw motor, the sliding seat and the electric cylinder are driven to slide along the guide seat, thus realizing the rapid positioning and adjustment of the cutting disc and improving the cutting efficiency.

[0016] (2). The titanium alloy cutting device can automatically receive the cut titanium alloy pipe through the receiving component. By contracting the output end of the electric cylinder to drive the square plate and the receiving plate to move below the titanium alloy pipe, the automation of receiving is realized, reducing manual operation, improving work efficiency, and facilitating the subsequent operation of the staff to take the material.

[0017] (3) The titanium alloy cutting device uses the cooperation of a return spring and an elastic ball through an auxiliary blanking component. Through the movement generated by the hemispherical protrusion squeezing the convex rod, the vibration of the filter plate is realized, assisting the waste chips to pass through the filter plate, further simplifying the blanking process and reducing the difficulty of waste collection. At the same time, during the cutting process, when the hemispherical protrusion squeezes the convex rod to move, the convex rod rotates relative to the round rod, and the knocking rod does not move, improving the stability during the cutting of the cutting disc.

The three-jaw chuck 2 is connected to the output end of a speed reducer 21, and the speed reducer 21 is connected to the output end of a main motor 22. By rotating the output shaft of the main motor 22, the speed reducer 21 is driven to work, and then the three-jaw chuck 2 is driven to rotate at a reduced speed to assist in the subsequent cutting of the titanium alloy pipe. A cutting mechanism 3, a material receiving assembly 6, and an auxiliary material discharging assembly 7 are arranged inside the machine body 1. A filter plate 4 is arranged below the cutting mechanism 3, and a collection box 5 is slidably connected to the bottom inner wall of the machine body 1.

[0023] In the embodiment of the present invention, in order to ensure the cutting quality of the titanium alloy, the cutting components are further improved. The cutting mechanism 3 includes an electric cylinder 31, a guide rod 35, and a driving motor 37. A fixing member 32 is fixedly connected to the output end of the electric cylinder 31. One side of the fixing member 32 away from the electric cylinder 31 is hinged with a hinge rod 33. One end of the hinge rod 33 away from the fixing member 32 is hinged with a T-shaped member 34. The guide rod 35 is installed on the outer wall of the T-shaped member 34. An installation frame 36 is fixedly connected to the outer wall of the electric cylinder 31. The guide rod 35 penetrates through the installation frame 36 and is slidably connected to the installation frame 36. The driving motor 37 is installed on the outer wall of the T-shaped member 34. The output shaft of the driving motor 37 is fixedly connected to a cutting disc 38. By starting the electric cylinder 31, the output end of the electric cylinder 31 contracts, so that the fixing member 32 drives the hinge rod 33 to move, and then the two T-shaped members 34 drive the two cutting discs 38 to move towards each other. At the same time, the driving motor 37 is started to complete the cutting of the titanium alloy pipe. The two cutting discs 38 apply cutting forces at the same time to prevent the titanium alloy pipe from deforming under the action of the cutting pressure, improve the cutting quality, reduce the wear of the cutting discs 38, and improve the cutting quality and part accuracy.

[0024] Further, in order to be able to adjust the position of the cutting disc 38, specifically, the electric cylinder 31 is installed on the outer wall of the sliding seat 39. The sliding seat 39 is slidably connected in the guiding seat 310. The sliding seat 39 is threadedly connected to the lead screw 311. One end of the lead screw 311 is rotatably connected to the inner wall of the guiding seat 310. The lead screw 311 is on the output shaft of the lead screw motor 312. The output shaft of the lead screw motor 312 drives the lead screw 311 to rotate. Then the sliding seat 39 moves in the guiding seat 310 to adjust the position of the electric cylinder 31, thereby realizing the rapid positioning and adjustment of the cutting disc 38 and improving the cutting efficiency.

[0025] In the embodiment of the present invention, in order to be able to receive the cut titanium alloy tube, specifically, the receiving component 6 includes a square plate 61. The square plate 61 is connected to the fixing member 32 through a connecting rod. A first straight rod 62 and a second straight rod 63 are hinged on the outer wall of the square plate 61. The ends of the first straight rod 62 and the second straight rod 63 far from the square plate 61 are both hinged to the receiving plate 64. A vertical rod 66 is fixedly connected to the bottom of the square plate 61. A connecting plate 67 is fixedly connected to the bottom of the vertical rod 66. A plurality of hemispherical protrusions 68 are provided on the outer wall of the connecting plate 67. There are a plurality of groups of the hemispherical protrusions 68, and the plurality of groups of hemispherical protrusions 68 are arranged in an equidistant array. The middle of the first straight rod 62 or the second straight rod 63 is hinged to a third straight rod 65. The end of the third straight rod 65 far from the first straight rod 62 or the second straight rod 63 is hinged and installed on the outer wall of the electric cylinder 31. The first straight rod 62 and the second straight rod 63 are parallel to each other. By the contraction of the output end of the electric cylinder 31, the fixing member 32 drives the square plate 61 to move. Under the action of the third straight rod 65, the first straight rod 62 and the second straight rod 63 drive the receiving plate 64 to move below the titanium alloy tube, realizing the receiving of the cut titanium alloy tube, thereby realizing the automation of receiving, reducing manual operation, improving work efficiency, and facilitating the subsequent operation of the staff to take the material.

[0026] Further, in order to speed up the collection of waste materials, specifically, the auxiliary blanking assembly 7 includes a limit block 71 fixedly connected to the outer wall of the mounting frame 36. The limit block 71 is penetrated by a round rod 72 and slidably connected to the round rod 72. One end of the round rod 72 close to the hemispherical protrusion 68 is provided with a convex rod 73, and the convex rod 73 is elastically connected to the round rod 72 through a torsion spring. The end of the round rod 72 away from the convex rod 73 is fixedly connected with a U-shaped member 74.

One end of the knocking rod 76 away from the slide rod 75 is fixedly connected with an elastic ball 78. After the U-shaped member 74 moves and resets in the direction of the hemispherical protrusion 68 under the reset force of the return spring, the elastic ball 78 contacts the upper surface of the filter plate 4. Through the reset of the square plate 61, the connecting plate 67 and the hemispherical protrusion 68 move away from the electric cylinder 31. The hemispherical protrusion 68 presses the convex rod 73, and the convex rod 73 drives the round rod 72 and the U-shaped member 74 to move, stretching the return spring. The slide rod 75 slides in the straight slot of the knocking rod 76, and the knocking rod 76 rotates around the hinge point of the support rod 77, and the elastic ball 78 moves away from the upper surface of the filter plate 4. Among them, the filter plate 4 is a V-shaped filter plate with high sides and low middle, which further facilitates the collection of waste chips. After the hemispherical protrusion 68 passes through the convex rod 73, the return spring resets, and the elastic ball 78 contacts the upper surface of the filter plate 4 again, realizing the vibration of the filter plate 4 and assisting the waste chips to pass through the filter plate 4, further simplifying the blanking process and reducing the difficulty of waste material collection. At the same time, during the cutting process, when the hemispherical protrusion 68 presses the convex rod 73 to move, the convex rod 73 rotates relative to the round rod 72, and the knocking rod 76 does not move, improving the stability of the cutting disc 38 during cutting.

After the position adjustment is completed, start the electric cylinder 31. The output end of the electric cylinder 31 contracts, and the fixing member 32 drives the hinged rod 33 to move. The two T-shaped members 34 drive the two cutting discs 38 to move towards each other. At the same time, start the drive motor 37 to complete the cutting of the titanium alloy pipe; S2. Start the main motor 22. The output shaft of the main motor 22 drives the reducer 21 to work. The output end of the reducer 21 drives the three-jaw chuck 2 to rotate at a reduced speed to assist the cutting disc 38 in cutting the titanium alloy pipe; S3. The output end of the electric cylinder 31 contracts, and the fixing member 32 drives the square plate 61 to move. Under the action of the third straight rod 65, the first straight rod 62 and the second straight rod 63 drive the material receiving plate 64 to move below the titanium alloy pipe, realizing the material receiving of the cut titanium alloy pipe.

At the same time, the material receiving plate 64 moves back to its original position. S5. During the reset movement of the square plate 61, the connecting plate 67 and the hemispherical protrusion 68 move away from the electric cylinder 31. The hemispherical protrusion 68 squeezes the convex rod 73, and the convex rod 73 drives the round rod 72 and the U-shaped member 74 to move, stretching the reset spring. The sliding rod 75 slides in the straight groove of the knocking rod 76, and the knocking rod 76 rotates around the hinge point of the support rod 77. The elastic ball 78 moves away from the upper surface of the filter plate 4. After the hemispherical protrusion 68 passes through the convex rod 73, the reset spring resets, and the elastic ball 78 contacts the upper surface of the filter plate 4 again, causing the filter plate 4 to vibrate, assisting the waste chips to pass through the filter plate 4 and enter the collection box 5 for collection.
