Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, and particularly relates to a bending machine with a protection structure. Background Art

[0002] A bending machine is a device widely used in the metal processing industry, mainly used for bending metal sheets into various required shapes. When operating a bending machine, safety is the primary consideration. A bending machine with a protection structure is mainly designed to improve operation safety and protect operators from injury. These protection structures can effectively prevent dangerous situations such as steel plates breaking and flying out during the bending process, thereby reducing the occurrence of work-related injuries.

[0003] In the utility model patent named "A Bending Machine with a Protection Structure" (application number 202323545885.7), it is proposed that "The utility model discloses a bending machine with a protection structure, which relates to the technical field of bending machines and includes a machine body and a positioning plate. The bottom of the machine body is fixedly connected with a base, and first springs are arranged at the left top and right top of the base. The inner wall of the top of the machine body is provided with a first telescopic rod, and an installation sleeve is fixed to the outer wall of the bottom of the second telescopic rod. In this bending machine with a protection structure, workpiece fragments splashing during the processing will be blocked by the protective cover to avoid injuring the operator, thereby improving the safety performance of the device. Pull up the connecting plate and the positioning pin. When the outer wall of the left side of the installation sleeve is unobstructed, slide the bending upper pressing tool into the left end of the installation sleeve, and then release the connecting plate and the positioning pin, so as to facilitate the installation and disassembly of the bending upper pressing tool, and the positioning pin limits the left end of the bending upper pressing tool to prevent the bending upper pressing tool from shifting during the bending process and affecting the processing effect of the bending machine." However, this utility model patent has the following problems:

[0004] 1. In this application, the problem that the equipped installation sleeve is inconvenient for installing the bending upper pressing tool is not considered, and the limiting effect achieved by relying on the positioning pin for positioning and limiting is also not good. Such a treatment method is not good because the installation and disassembly efficiency is low in this way and the best treatment effect cannot be achieved. Utility Model Content

Specific implementation mode

[0021] In order to enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below in conjunction with the drawings and embodiments.

[0022] As Figures 1 to 3 shown, a bending machine with a protection structure includes a support table, a bending lower template, a protective cover, an electric telescopic rod 1, an installation sleeve 2, and a bending upper pressing knife 3. A support seat 4 is installed on the bending upper pressing knife 3, and a guide block 5 matching the support seat 4 is installed on the installation sleeve 2. A rebound groove 6 is provided on the installation sleeve 2, a rebound spring 7 is installed in the rebound groove 6, and a rebound block 8 matching the support seat 4 is installed on the rebound spring 7;

A first spring 11 is installed in the first chute 9, a limit block 12 is installed on the first spring 11, a limit groove 13 matching the limit block 12 is provided on the support seat 4. A second spring 14 is installed in the second chute 10, a slide block 15 matching the second chute 10 is installed on the second spring 14, an operating rod 16 and a slide rod 17 are installed on the slide block 15, and an interaction block 18 matching the slide rod 17 is installed on the limit block 12.

[0024] Working principle description:

[0025] The basic function of this device is the same as that of the utility model patent named a bending machine with a protective structure (application number 202323545885.7). The device drives the bending upper pressing knife 3 and the bending lower template to work together through the electric telescopic rod 1 to bend the workpiece; it is worth noting that when the bending upper pressing knife 3 needs to be replaced, first press the operating rod 16 to make the slider 15 compress the second spring 14. The movement of the slider 15 drives the movement of the sliding rod 17 to contact the interactive block 18, and the interactive block 18 drives the movement of the limiting block 12 to compress the first spring 11. During this process, the limiting block 12 disengages from the limiting groove 13 and releases the limiting effect, and the return spring 6 rebounds to make the return block 8 eject the support seat 4 along the guiding block 5; when the bending upper pressing knife 3 needs to be installed, the support seat 4 is matched with the installation sleeve 2 and the guiding block 5. The support seat 4 drives the return block 8 to compress the return spring 7. At the same time, the support seat 4 makes the limiting block 12 retract into the first chute 9 and compress the first spring 11. When the limiting block 12 is matched with the limiting groove 13, the first spring 11 ejects the limiting block 12 and inserts it into the limiting groove 13 for fixed limiting.

[0026] Preferably, the guiding block 5 is installed with a rubber cushion layer. With such a structural design, the frictional damage suffered by the guiding block 5 is reduced, and the service life of the device is prolonged.

[0027] Preferably, the return block 8 is installed with a rubber cushion layer. With such a structural design, the frictional damage suffered by the return block 8 is reduced, and the service life of the device is prolonged.

[0028] Preferably, the operating rod 16 is provided with anti-slip lines. With such a structural design, the operation of the operating rod 16 is more convenient.

[0029] Preferably, the interactive block 18 is installed with a rubber cushion layer. With such a structural design, the frictional damage suffered by the interactive block 18 is reduced, and the service life of the device is prolonged.

[0030] The above embodiments only exemplarily illustrate the principles and effects of the present utility model, rather than being used to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
