Description

Technical Field

[0001] The utility model belongs to the field of punching machine protection devices, and more specifically relates to a punching processing outer protection cover. Background Art

[0002] At present, the stamping machine we call in daily life is a common name, which is what we often call a punching machine. The scientific name should be a press, which drives the flywheel through an electric motor, and drives the crank-connecting rod mechanism through a clutch and a transmission gear to make the slider move up and down, driving the stretching die to form the steel plate. The so-called double-action means that the press has two sliders, divided into an inner slider and an outer slider. The inner slider drives the punch or die of the die, and the outer slider drives the blank holder on the die. When stretching, the blank holder first moves to press the edge of the steel plate, and then the inner slider moves to stretch.

[0003] During the stamping operation, stamping debris will splash, and in severe cases, workpieces will splash, posing a certain threat to the personal safety of the operator. Some stamping machines are equipped with protective covers to prevent accidents. However, most of the existing protective covers are sealed, and the internal working conditions cannot be observed. If the machine is stuck or the workpiece is deformed, it is unknown, which affects production efficiency. In addition, the completely sealed shell affects the entry and exit of the workpiece, greatly reducing work efficiency. Therefore, it is necessary to design a removable stamping processing outer protective cover that is convenient for the entry and exit of the workpiece. Utility Model Content

[0004] During the stamping operation, the utility model can place the workpiece into the feeding channel through the feed shielding sheet. After the workpiece is placed in, the feed shielding sheet automatically falls down to protect the safety of the operator. The feeding channel facilitates the taking in and out of the workpiece. It can effectively prevent the operator's fingers from being crushed during the stamping process and prevent personal safety accidents during the stamping process. The stamping operation can be observed at any time through the visual window, and the transparent protective cover can prevent the splashing of stamping debris to protect the safety of the operator. It can be easily disassembled. When the machine is stuck or the workpiece is deformed, the machine can be stopped in time and the protective cover can be disassembled for maintenance and inspection, which improves the operation stability of the stamping process.

[0005] A stamping processing outer protective cover comprises a protective cover body for setting the punching head and the punching operation table of the punching machine inside, the protective cover body is in a side concave shape, a feeding channel is provided on the protective cover body, the feeding channel is located in the plane of the punching head and the punching operation table, a feed shielding piece is rotatably installed at the feed port of the feed channel, a visual window is provided on the front of the protective cover body, and a transparent protective cover with the visual window cover inside is rotatably installed on the protective cover body.

[0006] Furthermore, an upper mounting port and a lower mounting port are provided on the side of the protective cover body.

[0013] In order to facilitate the understanding of the utility model, the utility model will be described more comprehensively with reference to the relevant drawings below. Typical embodiments of the utility model are given in the drawings. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0015] like Figure 1As shown, a stamping processing outer protective cover includes a protective cover body 1 for arranging the punching head and the punching operating table of the punching machine inside, and the protective cover body 1 is in a side concave shape. The installation of the protective cover can effectively avoid the splashing of stamping debris while ensuring the normal operation of the stamping operation, and can even prevent the operator from being injured due to the splashing of the workpiece in serious cases, thereby protecting the operator's personal safety.

[0016] The protective cover body 1 is provided with a feeding channel 2, and the feeding channel 2 is located at the working plane of the punching head and the punching operation table to ensure the normal progress of the punching operation.

[0017] A feed shielding piece 3 is rotatably installed at the feed port of the feed channel 2. When the operator performs stamping operations, the workpiece is fed into the feed channel 2 through the feed shielding piece 3. When the workpiece is put inward, the feed shielding piece 3 rotates inward due to the entry of the workpiece. After the workpiece is put in, the feed shielding piece 3 automatically falls back. It is ensured that when the operator is working, the splashing debris generated by the stamping work will not splash out through the feed channel 2 and accidentally injure the operator. During operation, the operator can hold the workpiece to be stamped on both sides outside the feed channel 2, and observe the working conditions in the visual window 4 through the transparent protective cover 5. After the work is completed, the finished workpiece can be taken out through the side of the feed channel 2.

[0018] The front of the protective cover body 1 is provided with a visual window 4, which is convenient for the operator to observe the working condition of the workpiece. A transparent protective cover 5 is rotatably mounted on the protective cover body 1, which covers the visual window 4, to ensure that when the operator is working, the splashing debris generated by the stamping work will not splash out and accidentally injure the operator.

[0019] The side of the protective cover body 1 is provided with an upper mounting port 6 and a lower mounting port 7. The upper mounting port 6 is used to thread the protective cover body 1 with the mounting bracket on the casing, so that the protective cover body 1 can be firmly mounted on the casing. When disassembly is required, the nut can be rotated. The lower mounting port 7 is provided with a magnet, which is magnetically connected to the mounting bracket on the casing, which can reduce the time consumed during disassembly, improve work efficiency, and enable shutdown inspection as soon as possible. When the machine is stuck or the workpiece is deformed and the protective cover body 1 needs to be disassembled for shutdown inspection, it is only necessary to disassemble the upper mounting port 6 and use force to magnetically separate the lower mounting port 7.

[0020] Protective cover installation process and stamping operation process:

[0021] When installing the protective cover body 1, the protective cover body 1 is threadedly connected to the mounting bracket on the housing through the upper mounting port 6. After the fixing is completed, the magnet on the lower mounting port 7 is magnetically matched with the mounting bracket on the housing. During installation, make sure that the feeding channel 2 is in the same plane as the punch head and the punching operation table.

[0022] When the machine is stuck or the workpiece is deformed and the protective cover body 1 needs to be disassembled for shutdown inspection, it is only necessary to disassemble the upper mounting opening 6 and forcefully separate the lower mounting opening 7 by magnetic attraction to remove it.

[0023] When the operator performs the stamping operation, the workpiece is fed into the feeding channel 2 through the feed shielding sheet 3. When the workpiece is put inward, the feed shielding sheet 3 rotates inward due to the entry of the workpiece. After the workpiece is put in, the feed shielding sheet 3 automatically falls back. During operation, the operator can hold the workpiece to be stamped on both sides outside the feeding channel 2 and observe the working conditions in the visual window 4 through the transparent protective cover 5. After the work is completed, the completed workpiece can be taken out through the side of the feeding channel 2.

[0024] The embodiments of the utility model are described above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the utility model, ordinary technicians in this field can also make many forms without departing from the scope of protection of the utility model and the claims, which all fall within the protection of the utility model.
