A back press machine with automatic feeding and unloading

Abstract

This utility model relates to the field of back pressing equipment technology, specifically an automatic feeding and unloading back pressing machine. It includes a mounting platform, a feeding mechanism, a discharging mechanism, and a base plate. It further includes: the feeding mechanism is located on top of the mounting platform; the discharging mechanism is located on top of the mounting platform and on the side of the feeding mechanism; and the base plate is slidably mounted on top of the mounting platform. Through the feeding and discharging mechanisms, this utility model uses a second cylinder, under computer control, to gradually extend the pushing length, thereby moving the material feeding box to sequentially place the cutting tools between the fixed clamp and the moving clamp for feeding.

After the third cylinder drives the pressure roller to process the cutter, it drives the rotating plate to return. The rotating plate drives the base plate to move through the linkage, thereby disengaging from the fixture, and then the cutter falls out of the mounting table to complete the unloading. When the base plate moves to the trapezoidal platform, it returns to its original position under the action of the trapezoidal platform and the mounting block to carry out the next back pressing work. In this way, the processes of picking up, back pressing, and unloading can be completed quickly, and the production efficiency is increased several times compared with manual labor. It avoids downtime caused by manual shift changes and eliminates speed fluctuations caused by human operation, ensuring the efficient operation of the production line, avoiding workpiece positioning deviation due to fatigue or negligence, realizing stable workpiece gripping and placement, and significantly reducing the defect rate.

[0027] Example 1

[0028] like Figures 1-3 As shown, the present invention proposes an automatic feeding and unloading back pressing machine, including a mounting platform 1, a feeding mechanism, an unloading mechanism, and a base plate 419; it also includes:

[0029] The feeding mechanism is located on the top of the mounting platform 1 and is used to place the cutting tools one by one into the processing position via computer control;

[0030] The unloading mechanism is located on the top of the mounting platform 1 and on the side of the loading mechanism. It is used to automatically drop the tool downwards for unloading after the tool has finished processing.

[0031] The base plate 419 is slidably mounted on the top of the mounting platform 1. A linkage 420 is provided at the end of the base plate 419. The base plate 419 is used to provide support for the cutting tool and fix the position of the cutting tool when the cutting tool is performing the back pressing operation. When the unloading mechanism moves back, it drives the base plate 419 to move, thereby blocking the cutting tool from the base plate 419 and causing the cutting tool to fall out of the mounting platform 1 for unloading.

[0032] The clamping assembly includes a cylinder 201, a push rod 202, a movable clamp 203, a support frame 206, and a fixed clamp 205. The cylinder 201 is located on the top of the mounting platform 1. The push rod 202 is located at the output end of the cylinder 201. The movable clamp 203 is located at the end of the push rod 202 away from the cylinder 201. The support frame 206 is located on the top of the mounting platform 1 and on the side of the movable clamp 203. The fixed clamp 205 is located at the end of the support frame 206 away from the mounting platform 1. The side of the movable clamp 203 is... There are two limit plates 204 symmetrically arranged about the movable clamp 203. The end of the limit plate 204 away from the movable clamp 203 is in contact with the side of the fixed clamp 205. When the cylinder 201 is activated, the cylinder 201 drives the movable clamp 203 to move through the push rod 202. When the movable clamp 203 is close to the fixed clamp 205, it clamps the tool. The limit plate 204 limits the two ends of the tool to prevent the position from shifting. When the movable clamp 203 is away from the fixed clamp 205, it releases the tool to facilitate unloading.

[0033] The feeding mechanism includes a fixed frame 301, a second cylinder 302, a second push rod 303, and a feeding box 304. The fixed frame 301 is located on the top of the mounting platform 1, the second cylinder 302 is located on the top of the fixed frame 301, the second push rod 303 is located at the output end of the second cylinder 302, and the feeding box 304 is located at the end of the second push rod 303 away from the second cylinder 302. A partition plate 305 is provided on the inner side of the feeding box 304, and a fixed plate 306 is slidably provided on the bottom of the feeding box 304. A support column 307 is provided on the bottom of the fixed plate 306 to support... The bottom of column 307 is connected to the top of mounting platform 1. The partition divides the feeding box 304 into multiple small boxes. The cutting tools are placed in each small box in sequence. The second cylinder 302 is activated. The second cylinder 302 drives the feeding box 304 to slide on the fixed plate 306 through the push rod 303. When the cutting tool in the feeding box 304 moves to the fixed clamp 205, the cutting tool slides out of the feeding box 304. The second cylinder 302 is controlled by the computer. The distance of each movement increases slightly, so that the cutting tools in the feeding box 304 are sequentially put into the clamping assembly.

[0034] Example 2

[0035] like Figures 4-5 As shown, this utility model proposes an automatic feeding and unloading press machine. Compared with Embodiment 1, this embodiment details the structure of the unloading mechanism.

[0036] The feeding mechanism includes a back-pressing assembly and a feeding assembly. The back-pressing assembly is located on the top of the mounting platform 1 and is used to reciprocate to thicken the back of the blade. The feeding assembly is located on the back-pressing assembly and is used to pull the base plate 419 to move after the back-pressing is completed, so that the blade back is removed from the mounting platform 1. The back-pressing assembly includes a mounting plate 401, a connecting frame 402, a cylinder 403, a push rod 404, and a mounting frame 414. The mounting plate 401 is located on the top of the mounting platform 1, the connecting frame 402 is located on the side of the mounting plate 401, the cylinder 403 is located inside the connecting frame 402, the push rod 404 is located at the output end of the cylinder 403, the mounting frame 414 is located at the end of the push rod 404 away from the cylinder 403, an extruder 416 is provided on the mounting frame 414, and a pressure roller 415 is rotatably provided at the end of the mounting frame 414 away from the push rod 404. The mounting frame 414 is divided into two... The device consists of two parts: one set vertically and the other set horizontally, with a sliding connection between them. The top of the horizontal part is connected to the extruder 416. When cylinder 3 403 is activated, it drives the mounting bracket 414 to move via push rod 3 404. The mounting bracket 414 drives the pressure roller 415 to move. As the pressure roller 415 moves forward, it rolls along the back of the blade. The extruder 416 presses the pressure roller 415 downward in its natural state. When the pressure roller 415 moves along the shape of the back of the blade, it will move on the mounting bracket 414. At this time, the extruder 416 continuously provides downward extrusion force to the pressure roller 415 to press the back of the blade.The feeding assembly includes a connecting block 405, a first telescopic rod 406, a first spring 407, a trapezoidal platform, and a second telescopic rod 417. The connecting block 405 is located outside the third push rod 404, and the distance from the connecting block 405 to the center of the pressure roller 415 exceeds the length of the base plate 419. The first telescopic rod 406 is located at the bottom of the connecting block 405, the first spring 407 is located outside the first telescopic rod 406, and a mounting block 408 is located at the bottom of the first telescopic rod 406. A baffle 409 is located on the side of the mounting block 408, and the bottom of the mounting block 408 is rotatably mounted. A rotating plate is provided, and a second spring is provided on the side of the rotating plate. A connecting plate is provided at the end of the second spring away from the rotating plate. The top of the connecting plate is connected to the side of the mounting block 408 away from the baffle 409. A trapezoidal platform is provided on the side of the mounting plate 401 away from the connecting frame 402. A second telescopic rod 417 is provided on the side of the mounting plate 401 and located below the trapezoidal platform. Two telescopic rods 417 are symmetrically arranged about the mounting plate 401. A third spring 418 is provided on the outer side of the second telescopic rod 417. The end of the second telescopic rod 417 away from the mounting plate 401 and the bottom The end of plate 419 is connected. Push rod 3 404 drives pressure roller 415 to the farthest end of the cutter, while simultaneously driving connecting block 405 to the side of linkage 420. Push rod 3 404 continues to move, causing rotating plate to contact linkage 420. Under the obstruction of linkage 420, rotating plate rotates. When rotating plate is completely disengaged from linkage 420, it abuts against baffle 409 under the action of spring 2. Baffle 409 restricts the position of rotating plate to keep it vertical. Then push rod 3 404 moves back, and during the return stroke, it passes through linkage 409. 420 drives the base plate 419 to move towards the mounting plate 401. At this time, the spring 3 418 and the telescopic rod 2 417 are compressed, thereby separating the mounting plate 401 from the cutter and completing the unloading. When the mounting block 408 moves to the trapezoidal platform, because wedge blocks are provided on both sides of the mounting block 408, the wedge blocks drive the telescopic rod 1 406 and the spring 1 407 to compress under the action of the trapezoidal platform, thereby driving the rotating plate to move upward until it disengages from the linkage 420. The linkage 420 returns to its original position under the action of the spring 3 418 and the telescopic rod 2 417.

[0037] In summary, when using this utility model, the cutting tools are arranged sequentially in the feeding box 304. Then, cylinders 201 and 302 are activated. Cylinder 302 drives the feeding box 304 to slide on the fixed plate 306 via push rod 303. When the cutting tool in the feeding box 304 moves to the fixed clamp 205, the cutting tool slides out of the feeding box 304 and into the space between the fixed clamp 205 and the movable clamp 203. Cylinder 201 drives the movable clamp 203 to move via push rod 202. When the movable clamp 203 approaches the fixed clamp 205, it clamps the cutting tool. Then, cylinder 403 is activated. Cylinder 403 drives the mounting frame 414 to move via push rod 404. The mounting frame 414 drives the pressure roller 415 to move. As the pressure roller 415 moves forward, it rolls along the back of the cutting tool to perform back pressing. As push rod 404 drives the pressure roller 415 to move to the farthest end of the cutting tool,... The connecting block 405 is moved to the side of the linkage 420. The push rod 404 continues to move, causing the rotating plate to contact the linkage 420. Under the obstruction of the linkage 420, the rotating plate rotates. When the rotating plate is completely separated from the linkage 420, it abuts against the baffle 409 under the action of the spring 2. Then the push rod 404 moves back. During the return stroke, the rotating plate moves the bottom plate 419 towards the mounting plate 401 through the linkage 420, thereby separating the mounting plate 401 from the cutter and completing the unloading. When the mounting block 408 moves to the trapezoidal platform, because there are wedge blocks on both sides of the mounting block 408, the wedge blocks drive the telescopic rod 406 and the spring 407 to compress under the action of the trapezoidal platform, thereby driving the rotating plate to move upward until it is separated from the linkage 420. The linkage 420 drives the bottom plate 419 to return to its original position under the action of the spring 418 and the telescopic rod 417.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
