Description

Technical Field

[0001] This utility model relates to the field of metal cutting technology, and in particular to a cutting device for titanium and titanium alloy plates. Background Technology

[0002] In the field of titanium and titanium alloy cutting, existing technologies mainly include sawing, laser cutting, and milling, each with its own characteristics and application scenarios. For cutting titanium plates and titanium alloy sheets, sawing is the mainstream processing method.

[0003] However, existing titanium plates or titanium alloy plates have some problems in cutting and processing: the cutting process is cumbersome, requiring the titanium alloy plate to be fixed first, and then unfixed and transferred after cutting, resulting in low efficiency and discontinuous processing. Therefore, there is an urgent need for a cutting device for titanium and titanium alloy plates that can simplify the cutting process. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the present invention provides a cutting device for titanium and titanium alloy plates that simplifies the cutting process and improves the cutting efficiency.

[0005] The technical solution of this utility model is: a titanium and titanium alloy plate cutting device, including a frame, and a clamping and feeding assembly and a cutting assembly disposed on the upper end face of the frame. The clamping and feeding assembly includes a material table disposed on the upper end of the frame. A rectangular slot is opened on the top of the material table. A slide rail and a lead screw are disposed at the bottom of the rectangular slot along the length direction of the material table. A slider is disposed on the slide rail. A nut is disposed on the lead screw. A slide platform is disposed on the slider and the nut. The upper end face of the slide platform is not higher than the upper end face of the material table. A support plate is disposed at one end of the slide platform, and a first cylinder is horizontally disposed at the other end. A horizontal clamping plate is disposed at the front end of the movable rod of the first cylinder. The horizontal clamping plate cooperates with the support plate to clamp the plate in the horizontal direction and drives the slide platform to convey the plate forward through the lead screw. A pressure sensor is embedded in the side of the support plate near the clamping plate. A second cylinder is vertically disposed at the upper end of the support plate. The movable rod of the second cylinder faces the slide platform and is disposed with a vertical clamping plate. The vertical clamping plate cooperates with the material table to clamp the plate in the vertical direction.

[0006] Furthermore, it is particularly preferred that a plurality of first transfer rollers are arranged at intervals along the feeding direction on the upper surface of the material platform.

[0007] Furthermore, it is particularly preferred that the cutting assembly includes an arched support spanning the material table, the arched support consisting of a column and a beam, a linear drive mechanism being provided on the beam, a motor and a tool holder being provided at the movable end of the linear drive mechanism, a tool being provided on the tool holder, and the motor being connected to the tool in a transmission.

[0008] Furthermore, it is particularly preferred that the tool also includes an upper half-tool cover disposed on the tool holder and a lower half-tool cover disposed on the upper end of the frame. The lower half-tool cover is close to the starting position of the tool. When the tool is in the starting position, the tool is covered by the upper half-tool cover and the lower half-tool cover in all directions except the tool feed direction.

[0009] Furthermore, it is particularly preferred that a third cylinder is horizontally arranged on the upper end of the frame opposite to the lower half of the blade cover. The movable rod of the third cylinder is provided with an abutment block. The abutment block has a through groove on the side facing the lower half of the blade cover. An infrared sensor is provided in the through groove. The infrared sensor includes a transmitter and a receiver arranged on opposite sides in the through groove. When the blade moves to the designated position, part of the blade will penetrate into the through groove and be blocked between the transmitter and the receiver.

[0010] Furthermore, it is particularly preferred that the discharge end of the frame is provided with a receiving assembly, the receiving assembly including a base frame, the upper end surface of the base frame is provided with second material transfer rollers at intervals along the discharge direction, an inclined platform is provided between the base frame and the frame, and a vertical plate and a movable plate are provided on the side of the base frame away from the inclined platform, and a plurality of springs are provided between the vertical plate and the movable plate.

[0011] Furthermore, it is particularly preferred that a material pushing assembly is provided on one side of the base frame, the material pushing assembly including a fourth cylinder mounted on the base frame, a push plate being mounted on the movable rod of the fourth cylinder, and the lower end of the push plate being slightly higher than the height of the second material transfer roller.

[0012] The beneficial effects are:

[0013] 1. This utility model uses a horizontal clamping plate and a support plate to clamp the sheet metal, which plays a role in stabilizing the sheet metal during the cutting process. In addition, when the lead screw drives the slide table to reciprocate, it can move the sheet metal forward in conjunction with the clamping effect of the horizontal clamping plate and the support plate. Furthermore, by controlling the conveying distance each time, continuous and batch processing can be achieved, which greatly improves the cutting efficiency.

[0014] 2. This utility model reduces the friction between the material and the material platform during the material transfer process by setting a first material transfer roller on the material platform, thereby improving the smoothness of material transfer.

[0015] 3. The upper and lower blade covers of this utility model can play a protective role, not only preventing personnel from touching the blade, but also preventing cutting debris from flying during cutting.

[0016] 4. The third cylinder of this utility model drives the abutment block to clamp the plate, which not only plays a clamping role, but also the infrared sensor in the through groove of the abutment block can limit the cutting tool. When the cutting tool triggers the infrared sensor, it indicates that the plate has been cut. At this time, the cutting tool can be driven back to the starting position by the linear drive mechanism.

[0017] 5. The material receiving assembly of this utility model can orderly realize the unloading of the cut plate. Through the buffer cooperation of the movable plate and the spring, the cut material falls smoothly and prevents collision damage. The material pushing assembly can push the cut material away from the base frame. The height of the base plate is low, the unloading is relatively safe, and the probability of damage when the cut material falls is small. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0024] like Figure 1-4 The titanium and titanium alloy sheet cutting device shown includes a frame 1 for supporting the device. A clamping and feeding assembly 2 and a cutting assembly 3 are disposed on the upper surface of the frame 1. The clamping and feeding assembly 2 is used to clamp the titanium alloy sheet and convey it to the cutting end, while the cutting assembly 3 is used for cutting the sheet. For details, refer to [reference needed]. Figure 1The clamping and feeding assembly 2 includes a material platform 21, which is fixed to the upper end of the frame 1 and arranged along the feeding direction of the sheet metal. A rectangular slot 210 is formed at the top of the material platform 21, and a slide 26 reciprocates along the feeding direction within the rectangular slot 210. The slide 26 has components for clamping the sheet metal. A lead screw 23 and a nut 25 for driving the slide 26 are provided within the rectangular slot 210. Specifically, in this embodiment, the lead screw 23 is arranged along the length direction of the material platform 21 (i.e., the feeding direction), and one end of the lead screw 23 is driven by a servo motor. Additionally, slide rails 22 are arranged parallel to each other on both sides of the lead screw 23. The nut 25 is mounted on the lead screw 23, the slider 24 is mounted on the slide rails 22, and the slide 26 is mounted on the slider 24 and rotates in cooperation with the nut 25. It should be noted that the upper surface of the slide 26 is not higher than the upper surface of the material platform 21. Furthermore, refer to... Figure 2 One end of the slide table 26 is provided with a support plate 27, and the other end is horizontally provided with a first cylinder 28. The front end of the movable rod of the first cylinder 28 is provided with a horizontal clamping plate 29. When the first cylinder 28 drives the horizontal clamping plate 29 to approach the support plate 27, it completes the horizontal clamping of the material. Furthermore, a pressure sensor 4 is embedded in the side of the support plate 27 near the clamping plate. The pressure sensor 4 is used to detect the clamping force and provide timely feedback to the control system (PLC control system, not shown in the figure). During the clamping process, when the pressure reaches the preset value, the control system will control the first cylinder 28 to hold. In addition to horizontal clamping, vertical clamping can also be performed. Specifically, a second cylinder 5 is vertically provided at the upper end of the support plate 27. The movable rod of the second cylinder 5 faces the slide table 26 and is provided with a vertical clamping plate 51. The vertical clamping plate 51 cooperates with the material table 21 to achieve vertical clamping of the material.

[0025] During material transfer, the control system controls the servo motor to rotate and drives the slide table 26 to move away from the cutting assembly 3. After reaching a preset distance, the first cylinder 28 is used to clamp the sheet metal, and then the slide table 26 is driven to move towards the cutting assembly 3, simultaneously conveying the sheet metal forward. After reaching the designated position, the second cylinder 5 operates, the movable rod extends and drives the vertical clamping plate 51, achieving vertical clamping of the sheet metal. At this point, material transfer is complete, and cutting can begin. In a preferred embodiment, to maintain smooth and even material transfer, multiple first transfer rollers 8 are spaced apart along the feeding direction on the upper surface of the material table 21. By setting the first transfer rollers 8, the friction between the sheet metal and the material table 21 is reduced, making the resistance to transferring the sheet metal smaller.

[0026] In a preferred embodiment, multiple rectangular slots 210 can be provided. Each rectangular slot 210 is equipped with a corresponding slide table 26, a first cylinder 28, a horizontal clamping plate 29, a second cylinder 5, a vertical clamping plate 51, a support plate 27, a pressure sensor 4, a nut 25, and a slider 24. Thus, when the material is long enough, multiple first cylinders 28 operate synchronously, ensuring the material is held upright during clamping to prevent skewing and affecting clamping and material transfer. By providing multiple such slots, the device can adapt to materials of different lengths.

[0027] This device can automatically clamp the sheet blank and automatically feed it forward, which not only saves the time spent clamping the sheet but also allows for rapid feeding, thereby greatly improving cutting efficiency.

[0028] like Figure 3 As shown, in one specific embodiment, the cutting assembly 3 includes an arched support 31, a motor 33, a tool holder 34, and a cutting tool 35. Specifically, the arched support 31 spans the material table 21 and is composed of a column 310 and a crossbeam 311. The column 310 is fixed to the upper end of the frame 1, and the crossbeam 311 is located at the upper end of the column 310. A linear drive mechanism 32 is provided on the crossbeam 311 to drive the cutting tool 35 to move. The motor 33 and the tool holder 34 are located at the movable end of the linear drive mechanism 32, and the cutting tool 35 is located on the tool holder 34. The motor 33 is connected to the cutting tool 35 for transmission. In this embodiment, the linear drive mechanism 32 can be a linear slide, a linear motor module, or anything else that can achieve linear reciprocating motion. In this embodiment, the cutting tool 35 is a circular saw, and the cutting tool 35 is transmitted to the motor 33 via a belt or sprocket.

[0029] Furthermore, it also includes an upper half-blade cover 61 and a lower half-blade cover 62 for protection. The upper half-blade cover 61 is mounted on the blade holder 34 and moves synchronously with the blade holder. The lower half-blade cover 62 is mounted on the upper end of the frame 1 and is relatively fixed. The position of the lower half-blade cover 62 is at the starting position of the blade 35, that is, the initial position of the blade 35 before the machine is started. When the blade 35 is in the starting position, except for the feed direction of the blade 35, the other directions of the blade 35 are covered by the upper and lower half-blade covers 62. That is, except for the side close to the cutting, the other positions of the blade 35 are covered by the upper half-blade cover 61 and the lower half-blade cover 62 to prevent personnel from contacting the blade tip. On the other hand, since the blade 35 moves in the cutting direction, the waste generated by cutting will splash as the cutting is carried out. The upper half-blade cover 61 and the lower half-blade cover 62 also have the function of preventing waste from splashing.

[0030] like Figure 3 and Figure 4As shown, a third cylinder 7 is horizontally arranged on the upper end of the frame 1, opposite to the lower half-blade cover 62. A stop block 71 is provided on the movable rod of the third cylinder 7. A through groove 72 is opened on the side of the stop block 71 facing the lower half-blade cover 62. An infrared sensor 73 is provided in the through groove 72. The infrared sensor 73 includes a transmitter and a receiver, which are located on opposite side walls in the through groove 72. When the receiver can continuously receive the signal from the transmitter, the cutting assembly 3 continues to operate. When the plate is cut, a part of the blade 35 will extend into the through groove 72 and block the transmitter and receiver. At this time, the receiver does not receive a signal, which means that the plate is cut. At this time, a signal can be sent to the control system, which will control the cutting assembly 3 to return to the initial position and perform material transfer.

[0031] refer to Figure 1 In a preferred embodiment, the device further includes a receiving assembly disposed at the discharge end of the frame 1. The receiving assembly includes a base frame 91, with multiple second transfer rollers 92 spaced apart along the discharge direction on the upper surface of the base frame 91. A ramp 93 is provided between the base frame 91 and the frame 1. The cut sheet metal slides down the ramp 93 onto the base frame 91 and is pushed away by the pushing assembly 10. To reduce impact damage during the slide, a vertical plate 94 and a movable plate 95 are provided on the side of the base frame 91 away from the ramp 93, and multiple springs 96 for cushioning are provided between the vertical plate 94 and the movable plate 95. The sheet metal sliding down onto the base frame 91 is smoothly stopped on the upper surface of the base frame 91 by the cushioning effect of the movable plate 95 and the springs 96. The second transfer rollers 92 reduce wear. The material pushing assembly 10 is located on one side of the base frame 91. It includes a fourth cylinder 110 and a push plate 120. The fourth cylinder 110 is located on a support frame on one side of the base frame 91, and the push plate 120 is located on the movable rod of the fourth cylinder 110. It should also be noted that the lower end of the push plate 120 is slightly higher than the height of the second material conveying roller 92 to ensure that there is no interference during the material pushing process.

[0032] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the inventive concept, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
