[0028] Example 1

[0029] Reference Figure 1 to Figure 6 , which is the first embodiment of the utility model, provides a wear-resistant and high-precision mechanical press. The wear-resistant and high-precision mechanical press includes a main body component 100 and a protective component 200. The two can cooperate to separate the drive motor from the punch when the door is opened.

[0030] The main body component 100 includes a punch 101, a pressure plate 102, a punching rod 103, a movable sleeve 104, a rotating plate 105 and a positioning plate 106. The pressure plate 102 is arranged above the punch 101, the punching rod 103 is fixed to the top of the pressure plate 102, the movable sleeve 104 is fixed to one end of the punching rod 103, the rotating plate 105 is inserted into one side of the movable sleeve 104, the rotating plate 105 is movably connected to the movable sleeve 104, the positioning plate 106 is sleeved on the outside of the rotating plate 105, and the positioning plate 106 and the rotating plate 105 are movably connected.

[0031] The punch press 101 is a mechanical equipment used for metal processing, which is mainly used for blanking, punching, forming and other processing operations on metal plates. When it is necessary to punch the workpiece, the workpiece is first placed on the punch press 101, and then the rotating plate 105 is rotated. There are two rotating plates 105, which are respectively arranged on both sides of the movable sleeve 104. The rotating plate 105 can drive the movable sleeve 104 to move up and down by rotating. The movement of the movable sleeve 104 can drive the punch rod 103 to move. At this time, the movement of the punch rod 103 will drive the pressure plate 102 to move. The workpiece can be punched by the up and down reciprocating motion of the pressure plate 102. There are two positioning plates 106, which are fixed in the punch press 101. The positioning plate 106 is used to support the rotating plate 105 to prevent the rotating plate 105 from shifting when rotating.

[0032] The protection assembly 200 is disposed on the punch press 101 and includes a protection member 201 , a limit member 202 and a clutch member 203 . The protection member 201 is disposed on the punch press 101 , the limit member 202 is located on the protection member 201 , and the clutch member 203 is located on one side of the rotating plate 105 .

[0033] When punching the workpiece, the punch press 101 can be closed by closing the protective member 201 to prevent the staff's limbs from entering under the pressure plate 102 and causing injuries to the staff when punching the workpiece. After the protective member 201 is closed or opened, in order to prevent the protective member 201 from moving on its own, the protective member 201 can be limited by the setting of the limit member 202 to prevent the protective member 201 from moving on its own. After the protective member 201 is opened, the staff needs to place the workpiece on the punch press or remove it from the punch press. The drive of the rotating plate 105 can be released by the setting of the clutch member 203, and the rotating plate 105 will not rotate at this time. After the protective member 201 is closed, the clutch member 203 will drive the rotating plate 105 to rotate, thereby punching the workpiece.

[0034] Example 2

[0035] Reference Figure 1 to Figure 6 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0036] Specifically, the protective member 201 includes a protective frame 201a and a protective door 201b. The protective frame 201a is fixed to the top of the punch press 101, and the protective door 201b is disposed on one side of the protective frame 201a.

[0037] The protection frame 201a can be set to protect both sides of the punch press 101 to prevent debris from splashing out when the workpiece is punched. There are two protection doors 201b, both located on one side of the protection frame 201a. When the workpiece is punched, the two protection doors 201b are moved toward each other to close them, thereby preventing the staff's limbs from entering under the pressure plate 102 and causing injuries.

[0038] Specifically, the protective member 201 further includes a moving frame 201c and a support rod 201d. The moving frame 201c is fixed to the bottom of the protective door 201b. The support rod 201d is plugged into one side of the moving frame 201c. The support rod 201d and the moving frame 201c are movably connected.

[0039] There are two movable frames 201c, both fixed at the bottom of the protective door 201b, and the support rod 201d is fixed to one side of the punch press 101. When the protective door 201b moves, the movable frame 201c can be driven to slide on the support rod 201d, thereby supporting the protective door 201b and preventing the protective door 201b from deviating during movement.

[0040] Specifically, the protective member 201 also includes a gear 201e, a rack 201f and a connecting frame 201g. The gear 201e is movably connected to one side of the punch press 101. The rack 201f is arranged on the top of the gear 201e. The rack 201f and the gear 201e are meshed. The connecting frame 201g is fixed to one side of the punch press 101.

[0041] There are two racks 201f, which are fixed at the bottom of two moving frames 201c respectively. When one of the protective doors 201b is moved, the protective door 201b will drive the moving frame 201c to move, and the moving frame 201c will drive the rack 201f to move. The rack 201f will drive the gear 201e to rotate when moving, and the gear 201e will drive the other rack 201f to move by rotating. At this time, the other rack 201f will move the other protective door 201b, so that the two protective doors 201b can move toward each other. To open or close the protective door 201b, only one of the protective doors 201b needs to be moved. The connecting frame 201g is used to protect the gear 201e and the rack 201f to prevent them from being damaged by being hit by external debris.

[0042] Specifically, the limiting member 202 includes a limiting block 202a and a moving rod 202b. The limiting block 202a is disposed on one side of the protective door 201b, and the moving rod 202b is fixed to the top of the limiting block 202a.

[0043] After the protective door 201b is closed, in order to prevent the protective door 201b from moving on its own, the limit block 202a is moved to one side of the protective door 201b so that the protective door 201b can be limited to prevent the protective door 201b from opening on its own. A limit groove corresponding to the limit block 202a is provided on the top of the protective door 201b. When the protective door 201b needs to be opened, the moving rod 202b is pulled, and the moving rod 202b drives the limit block 202a to move so that the limit block 202a moves to separate from the protective door 201b. At this time, the limit on the protective door 201b can be released, and then the protective door 201b can be opened and the protective door 201b is moved to the limit groove and the limit block 202a contacts. At this time, the limit block 202a will move into the limit groove, and the opened protective door 201b can be limited to prevent the protective door 201b from closing on its own.

[0044] Specifically, the limiting member 202 also includes a first spring 202c, a pressure plate 202d, a support sleeve 202e and a fixed sleeve 202f. The first spring 202c is sleeved on the outside of the moving rod 202b, the pressure plate 202d is fixed to one end of the first spring 202c, the support sleeve 202e is sleeved on the outside of the moving rod 202b, the support sleeve 202e and the moving rod 202b are movably connected, and the fixed sleeve 202f is sleeved on the outside of the support sleeve 202e.

[0045] The pressure plate 202d is sleeved on the outside of the moving rod 202b. When the moving rod 202b is moved, the pressure plate 202d can be driven to move. At this time, the movement of the pressure plate 202d can apply a squeezing force to the first spring 202c. The movement of the moving rod 202b will drive the limit block 202a to separate from one side of the protective door 201b. At this time, the limit on the protective door 201b can be released, and then the protective door 201b can be opened. When the protective door 201b is moved to the limit groove and contacts the limit block 202a, the moving rod 202b is released. At this time, the rebound force of the first spring 202c can make the limit block 202a engage with the limit groove, so that the opened protective door 201b can be limited to prevent the protective door 201b from closing by itself.

[0046] The support sleeve 202e is used to limit the moving rod 202b to prevent the moving rod 202b from deviating. The fixed sleeve 202f is fixed to the top of the protective frame 201a. The setting of the fixed sleeve 202f can support the support sleeve 202e to prevent the support sleeve 202e from deviating.

[0047] Specifically, the clutch component 203 includes a driving disk 203a, a clutch disk 203b, a movable rod 203c, a second spring 203d, a driving rod 203e and a support block 203f. The driving disk 203a is fixed to one side of the rotating plate 105, the clutch disk 203b is arranged on one side of the driving disk 203a, the movable rod 203c is fixed to one side of the clutch disk 203b, the second spring 203d is fixed to one side of the movable rod 203c, the driving rod 203e is fixed to one end of the movable rod 203c, the support block 203f is sleeved on the outside of the driving rod 203e, and the support block 203f and the driving rod 203e are movably connected.

[0048] The driving disk 203a is provided with a slot corresponding to the clutch disk 203b. When the driving disk 203a is engaged with the clutch disk 203b, the clutch disk 203b rotates to drive the driving disk 203a, and the driving disk 203a rotates to drive the rotating plate 105 to rotate to punch the workpiece.

[0049] After the protective door 201b is opened, the opening of the protective door 201b will drive the movable rod 203c to move, and the movable rod 203c will drive the driving rod 203e to move. When the movable rod 203c moves, it will apply a squeezing force to the second spring 203d. The movement of the movable rod 203c will drive the clutch disk 203b to separate from the driving disk 203a. At this time, the rotation of the clutch disk 203b will not drive the rotating plate 105 to rotate, thereby ensuring the safety of the staff. After the protective door 201b is closed, the rebound force of the second spring 203d will drive the clutch disk 203b to engage with the driving disk 203a. At this time, the rotation of the driving rod 203e will cause the driving disk 203a to rotate, so that the workpiece can be stamped.

[0050] The support block 203f is fixed in the punching machine 101. The drive rod 203e can be supported by the support block 203f to prevent the drive rod 203e from deviating.

[0051] Example 3

[0052] Reference Figure 3 to Figure 6 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0053] Specifically, the clutch 203 further includes a motor 203g and a fixing frame 203h. The motor 203g is plugged into one end of the driving rod 203e. The motor 203g and the driving rod 203e are movably connected. The fixing frame 203h is sleeved on the outside of the motor 203g.

[0054] The motor 203g is plugged into one side of the punch press 101, and the motor 203g is movably connected to the punch press 101. A block is provided at one end of the motor 203g, and a slot is provided at one end of the driving rod 203e. The block is engaged with the slot. When the motor 203g rotates, the block is driven to rotate, and the rotation of the block will drive the slot to rotate. The rotation of the slot will drive the driving rod 203e to rotate, and the rotation of the driving rod 203e will drive the driving disk 203a to rotate.

[0055] When the clutch disk 203b needs to be separated from the driving disk 203a, the movement of the movable rod 203c will drive the driving rod 203e to move. When the driving rod 203e moves, the card slot will slide on the card block, so that the moving movable rod 203c can be supported to prevent the movable rod 203c from shifting. The fixed frame 203h is fixed to one side of the punch press 101. The setting of the fixed frame 203h can support the motor 203g to prevent the motor 203g from shifting.

[0056] Specifically, the clutch 203 further includes a moving bar 203i, a movable frame 203j and a connecting rod 203k, wherein the moving bar 203i is arranged at one side of the movable rod 203c, the movable frame 203j is fixed at the top of the moving bar 203i, and the connecting rod 203k is fixed at one side of the movable frame 203j.

[0057] There are two moving bars 203i, which are respectively arranged on both sides of the movable rod 203c. A sliding groove is opened on the movable rod 203c. The moving bar 203i slides in the sliding groove. When the clutch disk 203b needs to be separated from the driving disk 203a, the connecting rod 203k is moved, and the connecting rod 203k drives the movable frame 203j to move, and the movable frame 203j drives the moving bar 203i to move. At this time, the movement of the moving bar 203i will drive the movable rod 203c to move, and the movement of the movable rod 203c can separate the clutch disk 203b from the driving disk 203a.

[0058] Specifically, the clutch member 203 further includes a slide frame 2031 and a slider 203m. The slide frame 2031 is fixed to one side of the punch press 101, and the slider 203m is fixed to one side of the connecting rod 203k.

[0059] A slide groove is provided in the slide frame 203l, and the slider 203m slides in the slide groove. A push block is fixed on the top of the protective door 201b. After the protective door 201b is opened, it will drive the push block to move. When the push block is moved to contact one side of the connecting rod 203k, the push block will squeeze the connecting rod 203k to move the connecting rod 203k. When the connecting rod 203k moves, it will drive the slider 203m to slide in the slide frame 203l, so as to ensure the stability of the connecting rod 203k when moving. The movement of the connecting rod 203k drives the movable frame 203j to move. At this time, the movement of the movable frame 203j can separate the clutch disk 203b from the driving disk 203a. At this time, the staff can take or replace the workpiece. At this time, if the motor 203g is accidentally turned on, the pressure plate 102 will not move, thereby ensuring the safety of the workers.

[0060] During use, when the protective door 201b needs to be opened, the limit on the protective door 201b is first released by moving the movable rod 202b. When the movable rod 202b is moved, the pressure plate 202d can be driven to move. At this time, the movement of the pressure plate 202d can apply a squeezing force to the first spring 202c. The movement of the movable rod 202b will drive the limit block 202a to separate from one side of the protective door 201b. At this time, the limit on the protective door 201b can be released.

[0061] Then the protective door 201b is opened, and the protective door 201b will drive the moving frame 201c to move, and the moving frame 201c will drive the rack 201f to move. When the rack 201f moves, it will drive the gear 201e to rotate. The gear 201e will drive another rack 201f to move by rotating. At this time, the other rack 201f will move the other protective door 201b, so that the two protective doors 201b can move toward each other, so that the protective door 201b can be opened. When the protective door 201b is moved to the limit groove and contacts the limit block 202a, the moving rod 202b is released. At this time, the limit block 202a can be engaged with the limit groove through the rebound force of the first spring 202c, so that the opened protective door 201b can be limited to prevent the protective door 201b from closing by itself.

[0062] After the protective door 201b is opened, it will drive the push block to move. When the push block is moved to contact one side of the connecting rod 203k, the push block will squeeze the connecting rod 203k to move the connecting rod 203k. When the connecting rod 203k moves, it will drive the slider 203m to slide in the slide frame 203l, so as to ensure the stability of the connecting rod 203k when moving. The movement of the connecting rod 203k drives the movable frame 203j to move. At this time, the movement of the movable frame 203j can drive the movable bar 203 i moves, and the movement of the movable bar 203i will drive the movable rod 203c to move. The movement of the movable rod 203c will drive the driving rod 203e to move. When the movable rod 203c moves, an extrusion force is applied to the second spring 203d. The movement of the movable rod 203c will drive the clutch disk 203b to separate from the driving disk 203a, and the staff can take or replace the workpiece. At this time, if the motor 203g is accidentally turned on, the pressure plate 102 will not move, thereby ensuring the safety of the workers.
