Description

Technical Field

[0001] This utility model relates to the field of aluminum bending limiting technology, and more specifically, to an aluminum bending limiting device. Background Technology

[0002] Aluminum bending is an important step in aluminum processing. It uses external force to plastically deform the aluminum along a specific axis, thereby changing its shape. During the bending process, the outer fibers of the aluminum are stretched, the inner fibers are compressed, while the length of the neutral layer remains basically unchanged. This process is mainly achieved by the pressure applied by the bending equipment.

[0003] When using existing equipment, the aluminum material is usually clamped at one end by a jig. However, this clamping method is unreliable. If the clamping force on both sides is uneven, the stress distribution of the aluminum material will be unbalanced during the bending process, causing one end of the aluminum material to curl up and the bending to fail.

[0005] This utility model is implemented as follows:

[0006] This utility model provides an aluminum bending limiting device, including legs and a support table. A limiting mechanism is provided on the top of the support table. The limiting mechanism includes...

[0007] A bending table is slidably mounted on top of a support table. A groove is provided on the top of the bending table, and two sliders are slidably installed inside the groove.

[0008] A bidirectional lead screw is rotatably mounted inside a slide groove, and two sliders are both sleeved on the surface of the bidirectional lead screw and threadedly connected to it.

[0009] The first motor is fixedly installed on the right side of the bending table, and the output end of the first motor is fixedly connected to the right side of the bidirectional lead screw.

[0010] The rotating cavity is located on one side opposite to the two sliders. A rotating shaft is fixedly installed inside the rotating cavity. A rotating rod is rotatably sleeved on the surface of the rotating shaft. A pressing block and a bearing block are integrally formed on the left side of the rotating rod.

[0011] In a preferred embodiment, movable cavities are provided on both the front and rear sides of the rotating cavity, and movable blocks are slidably installed inside the movable cavities. Movable slots that extend through the front and rear are provided on the movable blocks. Movable rods are fixedly installed on both the front and rear sides of the rotating rod, and the movable rods are slidably sleeved inside the movable slots.

[0012] In a preferred embodiment, a first spring is fixedly installed on the side of the inner wall of the movable cavity away from the movable block, and the other end of the first spring is fixedly connected to the movable block.

[0013] In a preferred embodiment, the top of the support table is provided with a sliding groove, and the bottom of the bending table is fixedly installed with a sliding block. The sliding block is slidably fitted inside the sliding groove. The top of the support table is fixedly installed with a first limiting block and a second limiting block. The first limiting block, the second limiting block and the bending table are arranged in a straight line.

[0014] In a preferred embodiment, a turntable is rotatably mounted inside the support table, the top of the turntable is fixedly connected to the bottom of the sliding block, and a second motor is fixedly mounted on the bottom of the support table, with the output end of the second motor fixedly connected to the bottom of the turntable.

[0018] The aluminum bending limiting device provided by this utility model has the following advantages:

[0019] 1. By setting a limiting mechanism, when the pressure block contacts the aluminum material, the pressure force causes the pressure block to drive the rotating rod to rotate around the pivot, so that the pressing block contacts the top of the aluminum material and presses it. This gives the aluminum material a pressing force when it is bent, preventing it from warping. Compared with the existing technology, this improves the limiting effect on the aluminum material and increases the success rate and processing quality of aluminum bending.

[0020] 2. By setting up a measuring mechanism, after the worker places the aluminum material on the bending table, the worker moves the aluminum material backward, thereby squeezing the abutment block. This causes the abutment block to move the measuring rod backward. The worker can judge the distance between the end of the aluminum material and the bending point of the aluminum material by the scale lines on the measuring rod. This eliminates the need for the worker to measure with measuring equipment, thus improving the degree of automation. After processing is completed, the aluminum material is no longer squeezed, and the abutment block returns to its original position by the rebound force of the second spring.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Reference Figure 1-5 This utility model provides a technical solution: an aluminum bending limiting device, including a support leg 1 and a support table 2. A limiting mechanism is provided on the top of the support table 2. The limiting mechanism includes a bending table 301, a bidirectional lead screw 304, a first motor 305, and a rotating cavity 306. The bending table 301 is slidably disposed on the top of the support table 2. A groove 302 is provided on the top of the bending table 301. Two sliders 303 are slidably installed inside the groove 302. The bidirectional lead screw 304 is rotatably installed inside the groove 302. Both sliders 303 are sleeved on the surface of the bidirectional lead screw 304 and threadedly connected to it. The first motor 305 is fixedly installed on the right side of the bending table 301. The output end of the first motor 305 is fixedly connected to the right side of the bidirectional lead screw 304. The rotating cavity 306 is located on the opposite side of the two sliders 303. A rotating shaft 307 is fixedly installed inside the rotating cavity 306. A rotating shaft 307 is rotatably sleeved on the surface of the rotating shaft 307. The rotating rod 308 has a pressing block 309 and a bearing block 310 integrally formed on its left side. By setting a limiting mechanism, the end of the aluminum material to be bent is placed on the bending table 301 and positioned between two sliders 303. The first motor 305 is started, which drives the bidirectional lead screw 304 to rotate. Since the two sliders 303 are respectively sleeved on the two ends of the bidirectional lead screw 304 with opposite thread directions, the two sliders 303 move simultaneously in opposite directions through the threaded connection with the bidirectional lead screw 304. When the bearing block 310 contacts the aluminum material, the pressing force causes the bearing block 310 to drive the rotating rod 308 to rotate around the rotating shaft 307, so that the pressing block 309 contacts the top of the aluminum material and presses it. This gives the aluminum material a pressing force when bending, preventing it from warping. Compared with the prior art, this improves the limiting effect on the aluminum material and increases the success rate and processing quality of aluminum material bending.

[0030] Reference Figure 1-5The rotating cavity 306 has movable cavities 311 on both the front and rear sides. A movable block 312 is slidably installed inside the movable cavity 311. A movable groove 313 that runs through the front and rear is opened on the movable block 312. Movable rods 314 are fixedly installed on both the front and rear sides of the rotating rod 308. The movable rods 314 are slidably sleeved inside the movable groove 313. A first spring 315 is fixedly installed on the side of the inner wall of the movable cavity 311 away from the movable block 312. The other end of the first spring 315 is fixedly connected to the movable block 312. By setting the movable block 312, when the rotating rod 308 rotates, it drives the movable rod 314 to squeeze the inner wall of the movable groove 313, causing the movable block 312 to move and squeeze the spring. When the aluminum material is released after processing, the rebound force of the first spring 315 can make the rotating rod 308 return to its original position for the next use.

[0031] Reference Figure 1-5 The top of the support table 2 is provided with a sliding groove 316. A sliding block 317 is fixedly installed at the bottom of the bending table 301. The sliding block 317 is slidably fitted inside the sliding groove 316. A first limiting block 318 and a second limiting block 319 are fixedly installed on the top of the support table 2. The first limiting block 318, the second limiting block 319 and the bending table 301 are arranged in a straight line. A turntable 320 is rotatably installed inside the support table 2. The top of the turntable 320 is fixedly connected to the bottom of the sliding block 317. A second electric... The output end of the second motor 321 is fixedly connected to the bottom of the turntable 320. By setting the turntable 320, the operator places the aluminum material into the interior of the first limiting block 318, the second limiting block 319, and between the two sliders 303. The aluminum material is limited by the first limiting block 318 and the second limiting block 319. The second motor 321 is started to drive the turntable 320 to rotate. The turntable 320 drives the bending table 301 to rotate around the central axis of the support table 2 through the sliding block 317, thereby bending the aluminum material.

[0032] Reference Figure 1-5The bending table 301 has a measuring mechanism inside, which includes a cavity 401. The cavity 401 is formed inside the bending table 301. A circular block 402 is slidably fitted inside the cavity 401. A measuring rod 403 is fixedly installed on the rear side of the circular block 402. The rear side of the measuring rod 403 extends to the rear side of the bending table 301. A stop block 404 is fixedly installed on the rear side of the measuring rod 403. A second spring 405 is fixedly installed on the rear side of the inner wall of the cavity 401. The other end of the second spring 405 is fixedly connected to the rear side of the circular block 402. The second spring 405 is fitted inside the cavity 401. The surface of the measuring rod 403 is equipped with a measuring mechanism. After the worker places the aluminum material on the bending table 301, the worker moves the aluminum material backward, thereby pressing the abutment block 404. This causes the abutment block 404 to move the measuring rod 403 backward. The worker can determine the distance between the end of the aluminum material and the bending point of the aluminum material by means of the scale lines on the measuring rod 403. This eliminates the need for the worker to use measuring equipment, improving the degree of automation. After processing is completed, the pressing of the aluminum material is removed, and the rebound force of the second spring 405 causes the abutment block 404 to return to its original position.

[0033] Specifically, the working process or principle of this aluminum bending limiting device is as follows: During use, the operator places the aluminum material inside the first limiting block 318, the second limiting block 319, and between the two sliders 303. The aluminum material is then moved backward, thus pressing against the abutment block 404. This causes the abutment block 404 to move the measuring rod 403 backward. The operator can determine the distance between the end of the aluminum material and the bending point of the aluminum material through the scale lines on the measuring rod 403. The first motor 305 is then started, driving the bidirectional lead screw 304 to rotate. Since the two sliders 303 are respectively fitted... Two sliders 303 are connected to the two ends of the double-acting lead screw 304 with opposite thread directions, so that the two sliders 303 move in opposite directions at the same time. When the pressure block 310 contacts the aluminum material, the pressure block 310 drives the rotating rod 308 to rotate around the rotating shaft 307, so that the pressing block 309 contacts the top of the aluminum material and presses it. The second motor 321 is started, which drives the turntable 320 to rotate. The turntable 320 drives the bending table 301 to rotate around the central axis of the support table 2 through the sliding block 317, thereby bending the aluminum material.
