Description

Technical Field

[0001] The utility model relates to the technical field of wrench processing, in particular to a punching machine with a protective device for processing wrench blanks. Background Art

[0002] A wrench is a commonly used installation and disassembly tool, usually made of carbon structural steel or alloy structural steel, and is specially used for tightening or disassembling round nuts on machine tools, vehicles, and mechanical equipment. It is widely used in our daily life. When the wrench is processed, it is generally fine-processed by a punch. In the process of punching the wrench, a lot of debris will be generated. The stamping pressure will cause the debris to splash, which will easily cause personal injury. In addition, the existing protective device generally has a complex installation structure, which is not convenient for disassembly and installation. In addition, if the wrench is not fixed during the processing, the position of the wrench will be offset, which is not conducive to the processing process of the wrench and reduces the processing efficiency.

[0003] Announcement No. CN213134826U proposes a protective device for a punch press for processing wrench blanks. The device uses a protective plate to block the splash of debris generated by the wrench body during processing. The installation of the protective plate is also more stable through the positioning shaft, and it is not easy to cause tipping when the debris collides with the protective plate, thereby protecting the safety of personnel; however, the device cannot effectively block the front placement area of ​​the punch press. During the processing, there is still a probability that debris will splash from the front to the outside, and the protective effect needs to be further improved. At the same time, the fixing process of the wrench is not convenient enough. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and then propose a punching machine with a protective device for processing wrench blanks.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A punch press with a protective device for processing wrench blanks comprises a punch press body, on which an electric push rod, symmetrically distributed first protective shells and a processing table located between two first protective shells are arranged, a placement groove for limiting the position of wrenches of the same specification is opened on the processing table, an electromagnet for adsorbing the wrench is embedded in the placement groove, the electric push rod is connected to a second protective shell in contact with the outer side surface of the first protective shell, and the first protective shell, the second protective shell and the punch press body surround the processing table to further reduce the amount of debris splashing outward.

[0007] The device can effectively block the processing table from all sides to further improve the chip splash prevention effect during the processing of the wrench body, the protective effect is further improved, the operating safety of the staff is improved, and the fixing process of the wrench is faster and firmer.

[0008] Furthermore, the first protective shell and the second protective shell are both transparent protective shells.

[0009] Furthermore, the punch body is symmetrically provided with fixing plates outside the first protective shell, one fixing plate is provided with an infrared transmitter, and the other fixing plate is provided with an infrared receiver, and both the infrared transmitter and the infrared receiver are electrically connected to the controller.

[0010] In the above scheme, in the initial state, the light emitted by the infrared transmitter can pass through the first protective shell and be received by the infrared receiver. At this time, the punch press can operate normally. However, when the wrench is manually taken and placed from the processing table, the infrared signal is blocked, and then the infrared receiver will feedback the signal to the controller, and then the controller will control the punch press body to stop working. This can further improve the safety of the wrench taking and placing process, further improve the protection effect, and minimize the occurrence of personal injury.

[0011] Furthermore, the second protective shell is symmetrically provided with rubber pads, and the first protective shell is provided with a movement groove allowing the rubber pads to be raised and lowered.

[0012] The above solution can avoid hard scratches between the first protective shell and the second protective shell on the one hand, and can ensure effective sealing around the processing table on the other hand.

[0013] Furthermore, a button is provided on the punch body, and the button and the electric push rod are electrically connected to the controller.

[0014] The above scheme can control the second protective shell to rise or fall through a button to facilitate the replacement of the wrench, and can further improve the debris splash prevention effect during the wrench processing process.

[0015] Furthermore, a processing table is movably provided on the punch body to adapt wrenches of different specifications for limiting and fixing.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The device can effectively block the processing table from all sides to further improve the chip splash prevention effect during the processing of the wrench body. Compared with the problem that the prior art cannot block the front placement area of ​​the punch body, the protection effect of the device is better, thereby improving the operating safety of the staff, and the fixing process of the wrench is faster and more secure.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0023] like Figure 1 and Figure 2 As shown, a punch press with a protective device for processing a wrench blank comprises a punch press body 1, which belongs to the prior art and its principle is not described. The punch press body 1 is provided with an electric push rod 13, a symmetrically distributed first protective shell 15 and a processing table 11 between two first protective shells 15, and a placement groove 12 for limiting the position of wrenches of the same specification is opened on the processing table 11, and an electromagnet 31 for adsorbing the wrench is embedded in the placement groove 12, and the electric push rod 13 is connected to a second protective shell 14 in contact with the outer side of the first protective shell 15, and the first protective shell 15, the second protective shell 14 and the punch press body 1 surround the processing table 11 to further reduce the amount of debris splashing outward.

[0024] Specifically, a processing table 11 is movably provided on the punch body 1 to adapt wrenches of different specifications for limiting and fixing.

[0025] For further optimization, a button 19 is provided on the punch body 1; the button 19 can be used to control the second protective shell 14 to rise or fall to facilitate the replacement of the wrench, and at the same time can further improve the debris splash prevention effect during the wrench processing.

[0026] It should be noted that the punch body 1, the electric push rod 13, the electromagnet 31 and the button 19 are all electrically connected to the controller, which is not shown in the figure.

After the wrench is placed in the placement slot 12, its handle body will be tightly fitted with the slot wall of the placement slot 12 and higher than the placement slot 12. Then the controller controls the electromagnet 31 to be energized to realize the adsorption and fixation of the wrench. Then, during the processing of the wrench body, the wrench will not be shifted in position. The fixing process of the wrench is more convenient and stable. After the wrench is placed, the staff triggers the button 19, and the button 19 feeds back the signal to the controller. Then the controller controls the electric push rod 13 to work to drive the second protective shell 14 to descend. The second protective shell 14 will contact the outer wall of the first protective shell 15 during the descent. The second protective shell 14 is in contact with the punch press body 1 to achieve the blocking of the placement area in front of the punch press body 1. When the second protective shell 14 is lowered, the controller controls the punch press body 1 to work to realize the processing of the wrench body. After the processing is completed, the staff triggers the button 19 again, and the electric push rod 13 drives the second protective shell 14 to move up to remove the obstruction of the placement area in front of the punch press body 1. At this time, the controller first controls the electromagnet 31 to cut off the power, and then the processed wrench can be taken out through the notches at both ends of the wrench and the placement slot 12 can be cleaned, and then another wrench of the same specification can be re-placed. When it is necessary to process wrenches of other specifications, the processing table 11 suitable for placing wrenches of other specifications can be replaced at this time; compared with the prior art, the present device can effectively block the processing table 11 from all sides to further improve the debris anti-splashing effect during the processing of the wrench body, the protection effect is further improved, the operating safety of the staff is improved, and the fixing process of the wrench is faster and firmer.

[0029] In some embodiments, Figure 1As shown, the first protective shell 15 and the second protective shell 14 are both transparent protective shells, and the punch body 1 is symmetrically provided with a fixing plate 16 on the outside of the first protective shell 15, an infrared transmitter 17 is provided on one fixing plate 16, and an infrared receiver 18 is provided on the other fixing plate 16, and the infrared transmitter 17 and the infrared receiver 18 are both electrically connected to the controller; in the initial state, the light emitted by the infrared transmitter 17 can pass through the first protective shell 15 and be received by the infrared receiver 18, and the punch body 1 can operate normally at this time, but when the manual wrench is taken from the processing table 11, the infrared signal is blocked, and then the infrared receiver 18 will feedback the signal to the controller, and then the controller controls the punch body 1 to stop working, which can further improve the safety of the wrench taking and placing process, further improve the protection effect, and minimize the occurrence of personal injury.

[0030] In other embodiments, Figure 1 As shown, the second protective shell 14 is symmetrically provided with rubber pads 21, and the first protective shell 15 is provided with a movement groove 22 that allows the rubber pad 21 to be raised and lowered. This embodiment can avoid hard scratches between the first protective shell 15 and the second protective shell 14 by raising and lowering the rubber pad 21 along the movement groove 22, while ensuring effective sealing around the processing table 11.
