Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a needle-punched preform cutting device. Background Technology

[0002] Needle-punched preforms, as an important component of composite material reinforcements, are widely used in high-end industrial fields such as aerospace, automobile manufacturing, and rail transportation. They have excellent properties such as high strength, high temperature resistance, and corrosion resistance. They are usually formed by stacking and reinforcing fiber materials through a needle-punching process to create a preform with a specific structure and size. During the production and processing of needle-punched preforms, they need to be cut into finished products of specific specifications according to actual application requirements.

[0003] As provided in the prior art, a needle-punched preform cutting device has a bracket installed on one side of the top of the base. The bracket is equipped with a coordinate adjustment mechanism, and the drive end of the coordinate adjustment mechanism is equipped with a cutting tool. By placing the product on two limit seats and then activating the horizontal drive device, the support rod is inserted into the product through the opening. At this time, the cylindrical needle-punched preform is supported by the two support rods. Then, the cutting device is adjusted to the corresponding position to cut the product. After the cutting is completed, by moving the support rod back, the cut product can be separated from the support rod by the baffle, allowing the product to fall into the discharge chute and complete the discharge. Compared with the prior art, this device is not only easy to install, requiring only simple placement, but also allows the product to be directly detached after cutting, with a fast discharge speed.

[0004] However, when the cutting device feeds the needle-punched preform, the staff still needs to manually move it to the cutting position, which increases the physical exertion of the staff. After the cutting is completed, the product falls directly into the discharge chute, which can easily cause damage to the product due to the impact force generated when it falls.

[0005] Therefore, it is necessary to provide a needle-punched preform cutting device to solve the above-mentioned technical problems. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] First Embodiment

[0028] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of the needle-punched preform cutting device provided by this utility model; Figure 2 for Figure 1 The diagram shows another perspective of the structure; Figure 3 for Figure 2The enlarged schematic diagram of part A is shown. A needle-punched preform cutting device includes: a support frame 1, wherein grooves 11 are provided on both sides of the back of the support frame 1;

[0029] Mounting frame 5 is fixedly mounted on the back of support frame 1. A second drive motor 51 is fixedly mounted on the top of mounting frame 5. A lead screw 52 is fixedly mounted on the output end of the second drive motor 51. A lifting frame 53 is threadedly connected to the outer side of the lead screw 52. The lifting frame 53 is slidably connected to the inner side of the slide groove 11.

[0030] Two first electric telescopic rods 31 are respectively disposed on both sides of the support frame 1. A first drive motor 32 is fixedly installed at one end of each of the two first electric telescopic rods 31, and a clamping plate 33 is fixedly installed at the output end of each of the two first drive motors 31.

[0031] A cutting blade 44 is disposed on the top of the support frame 1;

[0032] Two positioning slots 2 are respectively opened at both ends of the top of the support frame 1.

[0033] The needle-punched preform has a support mold inside, and both ends of the support mold are equipped with rotating shafts for connection.

[0034] The bottoms of both positioning grooves 2 are arc-shaped. When cutting the needle-punched preform, the rotating shaft can be locked on the inner side of the positioning groove 2, allowing the rotating shaft to rotate on the inner side of the positioning groove 2.

[0035] The extension and retraction of the first electric telescopic rod 31 can synchronously drive the first drive motor 32 and the clamping plate 33 to move, thereby clamping and releasing the needle-punched preform.

[0036] Support frames 3 are fixedly installed on the outer sides of the two first electric telescopic rods 31, and the two support frames 3 are respectively fixedly installed on both sides of the support frame 1.

[0037] By setting up the support frame 3, the first electric telescopic rod 31 can be stably installed on the side of the support frame 1.

[0038] A mounting bracket 4 is fixedly installed on the top of the support frame 1. A second electric telescopic rod 41 is fixedly installed on the top of the mounting bracket 4. A lateral moving component 42 is fixedly installed on the moving end of the second electric telescopic rod 41. A moving block 43 is fixedly installed on the moving end of the lateral moving component 42. The moving block 43 is fixedly installed on the back of the cutting blade 44.

[0039] The lateral movement assembly 42 includes a frame, a stepper motor, a rotating lead screw, and a slider. In use, the stepper motor drives the rotating lead screw to make a threaded connection inside the slider, thereby enabling the slider to move left and right inside the frame. This, in turn, drives the cutting blade 44 to move back and forth via the moving block 43, so as to adjust the position of the cutting blade 44.

[0040] The outer side of the lifting frame 53 is attached to the inner side of the mounting frame 5.

[0041] The working principle of the needle-punched preform cutting device provided by this utility model is as follows:

[0042] When feeding and cutting the needled preform, the needled preform is moved to the front of the support frame 1, and the rotating shafts at both ends of the inner mold of the needled preform are positioned at the top of the lifting frame 53. Then, the second drive motor 51 is started, causing the lead screw 52 to rotate, thereby making the lead screw 52 threadedly connected inside the lifting frame 53. This allows the lifting frame 53 to move the needled preform upwards. When the top of the lifting frame 53 is slightly higher than the top of the support frame 1, the second drive motor 51 is turned off. The needled preform is then pushed until both ends of the rotating shaft are at the top of the positioning groove 2. Then, the second drive motor 51 is started again, causing the lifting frame 53 to rotate upwards. 3. The needle preform is moved downwards, causing the rotating shaft to engage with the inner side of the positioning groove 2. Then, the first electric telescopic rod 31 is activated to extend it, causing the first drive motor 32 and the clamping plate 33 to move towards one end of the rotating shaft, thereby clamping the rotating shaft. Then, the lateral movement component 42 is activated to adjust the position of the cutting blade 44. Then, the second electric telescopic rod 41 is activated to move the cutting blade 44 downwards, causing the bottom of the cutting blade 44 to press against the top of the needle preform. Then, the first drive motor 32 rotates, causing the needle preform to rotate, thereby causing the cutting blade 44 to cut the needle preform.

[0043] After the cutting is completed, the lifting frame 53 moves upward again, thereby moving the rotating shaft out from the inner side of the positioning groove 2, and then pushing the needled preform until the rotating shaft moves away from the top of the support frame 1. Then the lifting frame 53 moves downward, thereby unloading the needled preform.

[0044] Compared with related technologies, the needle-punched preform cutting device provided by this utility model has the following beneficial effects:

[0045] The mounting frame 5, the second drive motor 51, the lead screw 52, ​​and the lifting frame 53 work together to feed the needled preform. When feeding the needled preform, the top of the lifting frame 53 pushes the needled preform upward, allowing it to move to the top of the support frame 1, thus completing the feeding of the needled preform without the need for manual handling by the workers, thereby reducing the physical exertion of the workers. When unloading the needled preform later, the lifting frame 53 can also move the cut needled preform downward to prevent it from falling directly and causing damage.

The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0048] Specifically, the difference in the needle-punched preform cutting device provided in the second embodiment of this application is that the support frame 1 is fixedly equipped with casters 6 on all four sides of its bottom.

[0049] Both ends of the support frame 1 are fixedly installed with side plates 7, and the side plates 7 are internally threaded with threaded rods 71.

[0050] A rotating plate 72 is fixedly installed on the top of the threaded rod 71, and a pad 73 is fixedly installed on the bottom of the threaded rod 71.

[0051] The working principle of the needle-punched preform cutting device provided by this utility model is as follows:

[0052] When in use, the position of the device can be adjusted by rolling the casters 6 on the ground. After adjusting to the appropriate position, the rotating plate 72 is rotated, which drives the threaded rod 71 to make a threaded connection inside the side plate 7. This causes the threaded rod 71 to move the pad 73 downward, thus supporting and limiting the support frame 1.

[0053] Compared with related technologies, the needle-punched preform cutting device provided by this utility model has the following beneficial effects:

[0054] The universal wheels 6, side plates 7, threaded rods 71, rotating plates 72, and pads 73 work together to move the device during use. The universal wheels 6 roll on the ground, which can move the device and increase its mobility. After moving to a suitable position, the pads 73 can also contact the ground to limit and support the device, thereby increasing its stability.
