The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that mutually excludes other embodiments.

[0027] Embodiment 1

[0028] Refer to Figures 1-6, which is the first embodiment of the present utility model. This embodiment provides a protective plate device for a punching machine. The protective plate device of the punching machine includes a protection assembly 200, which includes a protection bottom plate 201a, a first clamping block 201b, a second clamping block 201c, a protection plate 201d, a pressing block 201e, a pushing plate 201f, a connecting plate 201g and a convex block 201h. The first clamping block 201b is fixed on the protection bottom plate 201a, the second clamping block 201c is fixed on the protection bottom plate 201a, the protection plate 201d is located on the protection bottom plate 201a, the protection plate 201d is provided with a first clamping groove 201d-1, the first clamping block 201b can be engaged with the first clamping groove 201d-1, the protection plate 201d is provided with a second clamping groove 201d-2, the second clamping block 201c can be engaged with the second clamping groove 201d-2, a through groove 201d-3 is opened in the protection plate 201d, the pressing block 201e is arranged in the through groove 201d-3, the pushing plate 201f is fixed on the top of the pressing block 201e, the connecting plate 201g is located above the protection plate 201d, the connecting plate 201g is provided with a positioning groove 201g-1, and the convex block 201h is fixed on the inner wall of the positioning groove 201g-1.

[0029] There are multiple first clamping blocks 201b and second clamping blocks 201c, which are evenly distributed on the edge of the protection bottom plate 201a. There are multiple convex blocks 201h, which correspond to the second clamping blocks 201c, and the convex blocks 201h are evenly distributed in the positioning groove 201g-1.

[0030] The protection bottom plate 201a and the protection plate 201d are connected by a mortise and tenon structure. The first clamping block 201b and the second clamping block 201c serve as the tenons in the mortise and tenon structure, the first clamping groove 201d-1 and the second clamping groove 201d-2 serve as the mortises in the mortise and tenon structure, and the pressing block 201e serves as the wedge in the mortise and tenon structure.

[0031] The setting of the pressing block 201e is used to enhance the fastening of the connection between the protection bottom plate 201a and the protection plate 201d, and at the same time adjust the structural accuracy, so as to evenly disperse the force to the entire mortise and tenon structure, reduce the local pressure concentration, and thus extend the service life of the structure. The pushing plate 201f is used to push the pressing block 201e into the second clamping groove 201d-2.

[0032] The protective plate 201d is connected to the protective bottom plate 201a by the cooperation of the first clamping block 201b and the first clamping groove 201d-1, and the second clamping block 201c and the second clamping groove 201d-2. After ensuring that all the protective plates 201d are accurately connected, the connecting plate 201g is placed above the protective plate 201d, and the bottom of the convex block 201h is made to contact the top of the push plate 201f. Then, the connecting plate 201g is slowly squeezed to move downward. The connecting plate 201g drives the convex block 201h to move downward, and the convex block 201h pushes the push plate 201f to move along the through groove 201d-3. The push plate 201f drives the extrusion block 201e to move to the second clamping groove 201d-2. At the same time, the upper end face of the protective plate 201d is engaged with the positioning groove 201g-1, so as to stably connect the protective bottom plate 201a and the protective plate 201d, ensure the protective effect, and guarantee the safety of the operator.

[0033] Embodiment 2

[0034] Referring to Figures 1-6 , this is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0035] Specifically, there are multiple first clamping blocks 201b, and they are triangular in shape. The first clamping groove 201d-1 is in a corresponding shape.

[0036] By setting the first clamping block 201b to be triangular, the engagement between the first clamping block 201b and the first clamping groove 201d-1 is more stable, providing a more stable connection, reducing the possibility of loosening and displacement. At the same time, the triangular shape helps to evenly disperse the applied force in all directions, reducing the risk of local damage.

[0037] Specifically, the second clamping block 201c is rectangular in shape, and the number is the same as that of the first clamping block 201b. An extrusion groove 201c-1 is formed in the second clamping block 201c, and the extrusion block 201e can slide in the extrusion groove 201c-1. The extrusion groove 201c-1 is rectangular.

[0038] The extrusion groove 201c-1 can change the stress distribution. When the second clamping block 201c is subjected to an external force, the extrusion groove 201c-1 reduces stress concentration, thereby reducing the risk of damage to the second clamping block 201c.

[0039] Specifically, the extrusion block 201e is trapezoidal in shape. The length of the lower bottom edge of the extrusion block 201e is equal to the length of the extrusion groove 201c-1, and the length of the lower bottom edge of the extrusion block 201e is shorter than its upper bottom edge.

[0040] Through the trapezoidal setting, after the extrusion block 201e is driven into the extrusion groove 201c-1, due to the existence of the hypotenuse of the extrusion block 201e, a lateral expansion force will be generated, so that the tenon-mortise structure is more tightly combined together, enhancing the fastening effect between the protective bottom plate 201a and the protective plate 201d, and the trapezoidal wedge block is relatively easy to insert into the rectangular groove, facilitating installation.

[0041] Specifically, a spring 201i is fixed to the bottom end of the push plate 201f, and the other end of the spring 201i is fixed to the inner wall of the through groove 201d-3.

[0042] The spring 201i is used to apply a continuous upward thrust to the push plate 201f to ensure that the push plate 201f will not push the extrusion block 201e into the second card slot 201d-2 due to its own gravity in the absence of other external forces, avoiding hindering the engagement of the second card block 201c with the second card slot 201d-2.

[0043] Specifically, a baffle 201l is fixed to the edge of the protective bottom plate 201a.

[0044] There are two baffles 201l, which are respectively located on one side of the first card block 201b and the second card block 201c. When the protective bottom plate 201a is connected to the protective plate 201d, the baffle 201l will limit the front-back movement of the protective plate 201d, thereby preventing the protective plate 201d from tilting during use and resulting in a decrease in the protection effect.

[0045] Embodiment 3

[0046] Refer to Figures 1-6 , which is the third embodiment of the present utility model, and this embodiment is based on the first two embodiments.

[0047] Specifically, a locking plate 201m is provided on one side of the baffle 201l and the connecting plate 201g, and a threaded groove is opened in the locking plate 201m.

[0048] There are two locking plates 201m, which are respectively rotatably connected to the baffle 201l and the connecting plate 201g, and the directions of the threaded grooves in the two locking plates 201m are opposite, and there are three groups of locking plates 201m in total.

[0049] In the initial state, the locking plate 201m is in a horizontal state. After the protective plate 201d is installed, the locking plate 201m is rotated to a vertical state so that the locking plate 201m on the baffle 201l and the locking plate 201m on the connecting plate 201g are coaxial, and a bolt is used to connect with the threaded groove, thereby ensuring that the connecting plate 201g will not move under the push of the spring 201i, avoiding the movement of the protective plate 201d and resulting in a decrease in the protection effect, and further threatening the safety of the operator.

[0050] Specifically, the width of the protection plate 201d is equal to that of the positioning groove 201g-1, and the protection plate 201d can be engaged with the positioning groove 201g-1.

[0051] By engaging the top of the protection plate 201d with the positioning groove 201g-1, the installation stability of the protection plate 201d is enhanced, and the protection performance is prevented from being reduced due to the movement of the protection plate 201d.

[0052] Specifically, the through groove 201d-3 is communicated with the second card slot 201d-2.

[0053] When the push plate 201f pushes the extrusion block 201e to move downward, the extrusion block 201e will move from the through groove 201d-3 to the second card slot 201d-2, and then enter the extrusion groove 201c-1 to complete the engagement.

[0054] Specifically, it further includes a punching press assembly 100, which is arranged on one side of the protection bottom plate 201a.

[0055] The punching press assembly 100 is a pressure processing device that applies pressure to a mold to instantaneously cause plastic deformation of metal, plastic and other plates or profiles, so as to obtain workpieces with the required shape and size. This is the prior art, and this solution will not be elaborated much, and those skilled in the art can clearly understand the working principle.

[0056] During use, align the first card block 201b with the first card slot 201d-1, align the second card block 201c with the second card slot 201d-2, and then slowly move the protection plate 201d closer to the protection bottom plate 201a until the protection plate 201d is attached to the protection bottom plate 201a, and connect multiple protection plates 201d to the protection bottom plate 201a in sequence.

[0057] When it is determined that all the protection plates 201d are accurately connected, place the connecting plate 201g above the protection plate 201d, and make the bottom of the convex block 201h contact the top of the push plate 201f. Then slowly squeeze the connecting plate 201g to move downward. The connecting plate 201g drives the convex block 201h to move downward, the convex block 201h pushes the push plate 201f to move along the through groove 201d-3, the push plate 201f drives the extrusion block 201e to move to the second card slot 201d-2 and enter the extrusion groove 201c-1. The inclined surface of the extrusion block 201e will extrude the extrusion groove 201c-1, making the second card block 201c more tightly engaged with the second card slot 201d-2, enhancing the fastening effect between the protection bottom plate 201a and the protection plate 201d. At the same time, the top of the protection plate 201d is engaged with the positioning groove 201g-1, enhancing the installation stability of the protection plate 201d and preventing the protection performance from being reduced due to the movement of the protection plate 201d.

[0058] After the protective plate 201d is installed, rotate the locking plate 201m to a vertical state so that the locking plate 201m on the baffle 201l is coaxial with the locking plate 201m on the connecting plate 201g, and connect it with the threaded groove 201m-1 using bolts, so as to ensure that the connecting plate 201g will not move under the push of the spring 201i, avoid the movement of the protective plate 201d resulting in a decline in the protective effect, and thus threaten the safety of the operator.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
