Description

Technical Field

[0001] This utility model relates to the field of square tube processing technology, specifically a square tube processing sawing device. Background Technology

[0002] Square tube processing sawing equipment is a special equipment used to cut and bevele square tubes (such as square steel tubes, aluminum alloy square tubes, etc.), and is widely used in industries such as steel structure, machinery manufacturing, furniture and building materials.

[0003] For example, a square tube processing sawing device with authorization announcement number "CN222221314U" can perform fixed-length processing on the sawing position of the square tube. This not only improves the safety and convenience of operation, but also allows for the addition of an auxiliary cleaning mechanism to scrape the residual waste after sawing to the outside for auxiliary cleaning, thereby improving the practicality of the device. Traditional square tube processing sawing devices directly saw the square tube with a saw blade. During the sawing process, when the saw blade rotates at high speed and cuts into the square tube, the saw teeth collide periodically with the material, generating high-frequency impact force. As a hollow cross-section component, the square tube has low bending stiffness and will generate lateral vibration under impact, resulting in rough cuts and dimensional deviations. Utility Model Content

[0004] The purpose of this invention is to solve the problems of rough cuts and dimensional deviations caused by vibration of square tubes, and to propose a square tube processing sawing device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A square tube processing sawing device is designed, including a base and a first vertical plate. The first vertical plate is fixedly connected to the upper rear side of the base. A first electric telescopic rod is fixedly connected to the outer wall of the first vertical plate. The output end of the first electric telescopic rod is provided with a square tube fixing structure. A material feeding structure is provided on the upper right side of the base. A first horizontal plate and a second horizontal plate are fixedly connected from left to right in the middle of the upper part of the base.

[0007] The first electric telescopic pole in this configuration has a self-locking feature.

[0008] Preferably, the feeding structure includes a support, the end of the base is fixedly connected to the support, the upper end of the support is fixedly connected to the inclined plate, both ends of the inclined plate are fixedly connected to baffles, and the left end of the inclined plate is fixedly connected to the second horizontal plate.

[0009] The ramp in this setting is higher on the left and lower on the right, allowing the sawn square tubes to slide into the collection box.

[0010] Preferably, a second vertical plate is fixedly connected to the upper front side of the base, and a second electric telescopic rod is fixedly connected to the outer wall of the second vertical plate.

[0011] The second electric telescopic rod in this configuration has a self-locking feature.

[0012] Preferably, the output end of the second electric telescopic rod is fixedly connected to a sliding plate, the inner walls on both sides of the sliding plate are slidably connected to the sliding rod, a servo motor is installed at the end of the sliding plate, and a saw blade is fixedly connected to the output shaft of the servo motor (12).

[0013] The slider in this setting limits the movement of the slide plate and enables it to move linearly. The servo motor has a self-locking function.

[0014] Preferably, the two ends of the slide bar are fixedly connected to the second vertical plate, the first horizontal plate, and the second horizontal plate, respectively.

[0015] The second vertical plate, first horizontal plate, and second horizontal plate in this configuration provide fixed support for the sliding rod.

[0016] Preferably, the square tube fixing structure includes a square plate, a second limiting block, and a limiting plate. The output end of the first electric telescopic rod is fixedly connected to the square plate, the end of the square plate is fixedly connected to the first limiting block, the inner ends of the first and second horizontal plates are both fixedly connected to the second limiting block, and the left end of the first horizontal plate is fixedly connected to the limiting plate.

[0017] This setting has a gap between the two first limit blocks and the two second limit blocks, which provides space for the saw blade to move during sawing.

[0018] Preferably, a round rod is fixedly connected to the rear end of the square plate, the outer wall of the round rod is slidably connected to the cylinder, and the end of the cylinder is fixedly connected to the first vertical plate.

[0019] The cylindrical part of this feature serves to limit the movement of the rod and allows it to move linearly.

[0020] The square tube processing sawing device proposed in this utility model has the following advantages: through the cooperation of the square tube fixing structure and the first electric telescopic rod, the output end of the first electric telescopic rod moves to drive the first limiting block to move towards the square tube until the end of the first limiting block abuts against the square tube. At this time, both sides of the square tube abut against the first limiting block and the second limiting block respectively. There is a gap between the two first limiting blocks and the two second limiting blocks. This gap provides movement space for the saw blade to cut. In addition, the traditional method of fixing from both sides of the square tube will still cause vibration at the fixed position when the square tube is cut because the cutting point is far from the fixed position. This method of fixing at the cutting point reduces vibration, achieves the purpose of fixing the square tube, and reduces the phenomenon of rough cut and dimensional deviation caused by the vibration of the square tube.

A servo motor 12 is installed at the end of the slide plate 10. The servo motor 12 has a self-locking function. A saw blade 13 is fixedly connected to the output shaft of the servo motor 12. The two ends of the slide rod 11 are fixedly connected to the second vertical plate 8, the first horizontal plate 6, and the second horizontal plate 7, respectively. A round rod 14 is fixedly connected to the rear end of the square plate 501. The outer wall of the round rod 14 is slidably connected to the cylinder 15. The round rod 14 slides inside the cylinder 15. The cylinder 15 limits the round rod 14 and makes the round rod 14 move linearly. The end of the cylinder 15 is fixedly connected to the first vertical plate 3.

[0030] See attached document Figure 1-3 The feeding structure 2 includes a support 201. The support 201 is fixedly connected to the end of the base 1. An inclined plate 202 is fixedly connected to the upper end of the support 201. Both ends of the inclined plate 202 are fixedly connected to baffles 203. The left end of the inclined plate 202 is fixedly connected to the second horizontal plate 7.

[0031] See attached document Figure 1 , Figure 2 , Figure 4 and Figure 5 The square tube fixing structure 5 includes a square plate 501, a second limiting block 503 and a limiting plate 504. The output end of the first electric telescopic rod 4 is fixedly connected to the square plate 501. The end of the square plate 501 is fixedly connected to the first limiting block 502. The inner ends of the first horizontal plate 6 and the second horizontal plate 7 are both fixedly connected to the second limiting block 503. The left end of the first horizontal plate 6 is fixedly connected to the limiting plate 504.

[0032] Working principle:

[0033] When using a square tube processing sawing device:

[0034] Place the square tube to be cut on the first horizontal plate 6 and the second horizontal plate 7. Push the square tube to the right. The distance from the right end of the square tube to the saw blade 13 is the length of the square tube to be cut. Move the square tube to the appropriate position. At this time, activate the first electric telescopic rod 4. The output end of the first electric telescopic rod 4 moves, driving the square plate 501 to move. The movement of the square plate 501 causes the round rod 14 to slide inside the cylinder 15. The cylinder 15 limits the movement of the round rod 14 and makes the round rod 14 move linearly. The movement of the square plate 501 drives the first limiting block 502 to move towards the square tube until the end of the first limiting block 502 is pressed against the square tube. Then close the first electric telescopic rod 4. At this time, the two sides of the square tube are respectively against the first limiting block 502 and the second limiting block. Blocks 503 abut together to fix the square tube, reducing the roughness of the cut and dimensional deviation caused by the vibration of the square tube. Furthermore, there is a gap between the two first limiting blocks 502 and the two second limiting blocks 503. This gap provides movement space for the saw blade to cut. In addition, the traditional method of fixing from both sides of the square tube will still cause vibration at the fixed position when the square tube is cut because the cutting point is far from the fixed position. This method of fixing at the cutting point reduces vibration. Furthermore, the limiting plate 504 plays a limiting role in the movement of the square tube and provides a reference point when the square tube reaches the position to be cut, so that the square tube is tightly against the limiting plate, which facilitates subsequent sawing.

[0035] When the external power supply to the servo motor 12 is connected and the servo motor 12 is started, the output shaft of the servo motor 12 rotates, driving the saw blade 13 to rotate. This starts the second electric telescopic rod 9, and the output end of the second electric telescopic rod 9 moves, causing the slide plate 10 to slide on the slide rod 11. The slide rod 11 limits the slide plate 10 and causes it to move linearly. The movement of the slide plate 10 drives the servo motor 12 to move, and the movement of the servo motor 12 drives the saw blade 13 to move towards the square tube until the saw blade 13 contacts the square tube. The continued movement of the output end of the second electric telescopic rod 9 causes the saw blade 13 to cut into the square tube. This achieves the purpose of sawing. After sawing, the saw blade 13 is reset by the second electric telescopic rod 9, the servo motor 12 is turned off, and the first limit block 502 is moved away from the square tube by the first electric telescopic rod 4. The tube falls onto the inclined plate 202. The square tube will slide into the collection box on the right side due to the left-high and right-low setting of the inclined plate. To further explain, the baffle 203 is set to prevent the sawn square tube from falling to the outside. Repeat the above operation until the sawing of the square tube is completed. Turn off all power and take out the sawn square tube, thus completing the workflow of the square tube processing sawing device.
