Technical Field

[0001] The utility model relates to the technical field of mechanical transmission, in particular to a punch press clutch with a brake emergency stop device. Background Art

[0002] The punch clutch with a brake emergency stop device is a key component in the punch equipment. It can achieve smooth power transmission during normal operation, connect the motor and the transmission mechanism of the punch, and make the punch slider perform the punching action. When an emergency occurs and braking is required, the brake component will produce friction contact with the rotating component. Through the action of friction, the kinetic energy of the rotating component is consumed, causing it to gradually slow down until it stops. In the existing technology, when the rotating component is in contact with friction, usually only one side is in contact with friction. The friction force that can be generated is relatively small, which will result in insufficient braking force during braking, and the high-speed rotating components cannot be stopped quickly, which prolongs the braking time and increases the safety risk.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figures 2 to 6 , which is the first embodiment of the utility model, provides a punch clutch with a brake emergency stop device. The punch clutch with a brake emergency stop device includes a brake assembly 200, a closing assembly 300 and a punch assembly 100. The three can cooperate to brake the rotating part by friction on both sides, which makes it possible to stop the rotating part more quickly in an emergency.

[0030] The brake assembly 200 includes a movable plate 201a, a friction plate 201b, a brake plate 201c and an extrusion plate 201d. The friction plate 201b is fixed to one side of the movable plate 201a, the brake plate 201c is located on one side of the friction plate 201b, and the extrusion plate 201d is arranged on one side of the brake plate 201c.

[0031] A spring is fixed on one side of the movable plate 201a, and the spring is fixed to the inner wall of the punch frame 101. By moving the movable plate 201a, the movable plate 201a can apply an extrusion force to the spring when it moves. The movable plate 201a drives the friction plate 201b to separate from the brake plate 201c, and the rotating shaft 202f can be rotated at this time. When the rotating shaft 202f needs to be braked, the friction plate 201b and the brake plate 201c are driven to engage with each other by the rebound force of the spring, so that the rotating shaft 202f can be braked.

[0032] When the brake plate 201c is squeezed, the other side of the brake plate 201c will contact the squeezing plate 201d, so that both sides of the brake plate 201c can be squeezed, which makes it possible to stop the rotation of the shaft 202f more quickly in an emergency, greatly shortening the braking time.

[0033] The enclosing assembly 300 is arranged on one side of the movable plate 201a, and includes a protective frame 301a, a closed door 301b and a telescopic rod 301c. The protective frame 301a is located on one side of the movable plate 201a, and one end of the telescopic rod 301c is hinged to the inner wall of the protective frame 301a, and the other end is hinged to the bottom of the closed door 301b.

[0034] The flywheel 202a can be protected by the setting of the protective frame 301a. When the flywheel 202a needs to be maintained, the closed door 301b can be opened to facilitate maintenance of the flywheel 202a. The telescopic rod 301c can be retracted. When the closed door 301b is opened, the telescopic rod 301c can be driven to move, thereby supporting the closed door 301b and preventing the closed door 301b from deflecting.

[0035] Example 2

[0036] Reference Figures 2 to 6 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0037] Specifically, an air inlet X is opened on one side of the movable plate 201a.

[0038] The movable plate 201a can be moved by inflating the air inlet X. When the inflation is stopped, the movable plate 201a can be driven back to its original position by the rebound force of the spring. Inflating the air inlet X is a prior art and will not be elaborated in detail.

[0039] Specifically, a flywheel 202a is sleeved on the outer side of the moving plate 201a.

[0040] The rotation of the flywheel 202a drives the movable plate 201a to rotate. When the movable plate 201a rotates, the rotating shaft 202f rotates. When the movable plate 201a presses the brake plate 201c, the rotating shaft 202f stops rotating. At this time, the flywheel 202a will idle.

[0041] Specifically, a friction pad 202b is fixed to one side of the friction plate 201b, a bolt 202c is inserted into one side of the brake plate 201c, and the brake plate 201c and the bolt 202c are threadedly connected.

[0042] When the friction plate 201b moves, the friction pad 202b will contact the brake plate 201c, thereby increasing the friction force. The bolt 202c is inserted into one side of the punch frame 101, and the bolt 202c is threadedly connected to the punch frame 101. The brake plate 201c can be fixed to one side of the punch frame 101 through the setting of the bolt 202c.

[0043] Specifically, a squeezing pad 202d is fixed to one side of the squeezing plate 201d, a tightening sleeve 202e is provided in the squeezing plate 201d, and a rotating shaft 202f is inserted into the tightening sleeve 202e.

[0044] When the other side of the brake plate 201c contacts the friction pad 202b, the braking friction can be increased. Greater friction means that the kinetic energy of the rotating shaft 202f can be consumed faster, so that the rotating shaft 202f can stop more quickly in an emergency. The extrusion plate 201d can be connected to the rotating shaft 202f through the setting of the expansion sleeve 202e.

[0045] Specifically, a worm gear 302a is fixed to one end of the closed door 301b, a worm 302b is provided on one side of the worm gear 302a, and the worm gear 302a and the worm 302b are meshed.

[0046] The worm gear 302a can be driven to rotate by rotating the worm 302b, and the worm gear 302a can drive the closed door 301b to move and open by rotating, so that the closed door 301b can be opened to any position.

[0047] Specifically, a protective cover 302c is provided on the outer side of the worm 302b, and the protective cover 302c and the worm 302b are rotatably connected via a rotating shaft.

[0048] The protective cover 302c is fixed to one side of the protective frame 301a, and the worm 302b can be protected by the setting of the protective cover 302c.

[0049] Example 3

[0050] Reference Figures 1 to 6, which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0051] Specifically, a crank 302d is fixed to the bottom of the worm 302b, and a leakage groove Y is opened on one side of the protective cover 302c.

[0052] The setting of the crank 302d makes it convenient for the user to rotate the worm 302b, and the setting of the leakage groove Y can provide sufficient rotation space for the worm 302b.

[0053] Specifically, it also includes a punch assembly 100, which is arranged on the rotating shaft 202f, including a punch frame 101, and the punch frame 101 is sleeved on the outer side of the rotating shaft 202f.

[0054] The punch press frame 101 serves as the main structural frame of the punch press and bears the weight of each component of the punch press.

[0055] Specifically, a fastening plate 102 is fixed to one side of the protection frame 301 a.

[0056] There are two fastening plates 102 , both of which are fixed to one side of the punch frame 101 . The fastening plates 102 can support the protection frame 301 a and prevent the protection frame 301 a from deflecting.

[0057] During use, the movable plate 201a can be moved by inflating the air inlet X. When the movable plate 201a moves, it can apply a squeezing force to the spring, and the movable plate 201a drives the friction plate 201b to separate from the brake plate 201c. At this time, the rotating shaft 202f can be rotated. When the rotating shaft 202f needs to be braked, the inflation is stopped and the spring rebound force can drive the movable plate 201a to return to its original position. The spring rebound force drives the friction plate 201b to engage with the brake plate 201c, thereby braking the rotating shaft 202f.

[0058] The user rotates the crank 302d, which drives the worm 302b to rotate. The rotation of the worm 302b drives the worm wheel 302a to rotate, and the rotation of the worm wheel 302a drives the closed door 301b to move. The flywheel 202a can be maintained by moving and opening the closed door 301b. When opening the closed door 301b, it can be opened to any angle. The closed door 301b can be opened to the most appropriate angle according to the spatial layout and surrounding environment in the actual use scenario.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
