An expansion rod is provided at a position of the bottom of the connection frame corresponding to the connection piece. A convex block is provided at the bottom end of the expansion rod, and a compression spring is sleeved outside the expansion rod.

[0013] Preferably, one end of the compression spring is fixedly connected to the bottom of the connection frame, and the other end of the compression spring is fixedly connected to the outer wall of the convex block.

[0014] Preferably, a convex rod in sliding connection is inserted at a position of the inside of the connection frame corresponding to the end of each connection bar.

Detailed implementation manners

[0029] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0031] Please refer to Figures 1 to 7 , a multi-functional bottom plate of a stamping die provided by an embodiment of the present utility model, the multi-functional bottom plate of the stamping die includes: a bottom plate 1 and a positioning component 2.

[0032] In an embodiment of the present utility model, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a lower die frame 6 is provided on the top center of the bottom plate 1 through a support frame 11. Four groups of positioning components 2 are provided and evenly distributed on the four sides of the inner top of the support frame 11. The positioning component 2 includes a connecting strip 21. The top of the connecting strip 21 is fixedly connected to one side of the inner top of the support frame 11. A positioning piece 22 rotatably connected through a rotating shaft is provided on one side of the connecting strip 21 close to the lower die frame 6. And a connecting piece 221 fixedly connected is provided on the side of the positioning piece 22 away from the lower die frame 6. A return spring 23 is provided between the connecting piece 221 and the connecting strip 21. And both ends of the return spring 23 are fixedly connected to the corresponding connecting piece 221 and the connecting strip 21 respectively. A fixedly connected material guiding hopper 44 is provided below the lower die frame 6 on the inner top of the support frame 11. And a movably connected blanking hopper 4 is provided below the material guiding hopper 44. One end of the blanking hopper 4 is provided with a rotatably connected mounting frame 41. The bottom of the mounting frame 41 is connected to the top of the bottom plate 1. One side of the bottom of the blanking hopper 4 away from the mounting frame 41 is connected to a support rod 43 through a shaking spring 42. The bottom end of the support rod 43 is connected to the top of the bottom plate 1. And the side of the blanking hopper 4 provided with the shaking spring 42 is higher than the side provided with the mounting frame 41.

[0033] It should be noted that: by providing the positioning component 2 on the bottom plate 1, during the later use process, when the staff places the plate to be stamped on the lower die frame 6 and controls the stamping template 54 to move downward for stamping, the connecting piece 221 in the positioning component 2 can be smoothly squeezed by the telescopic rod 33 and the convex block 35 at the bottom of the connecting frame 3, so that the connecting piece 221 drives the corresponding positioning piece 22 to smoothly rotate towards the outer wall of the lower die frame 6 until the outer wall of the positioning piece 22 abuts against the side wall of the lower die frame 6, and the positioning of the plate can be smoothly completed without the staff manually placing and positioning the plate;

[0034] It should also be noted that: through the settings of the material guiding hopper 44 and the blanking hopper 4, during the later use, the material guiding hopper 44 can smoothly guide the stamped parts to fall into the lower blanking hopper 4 below. The impact force when the stamped parts fall into the blanking hopper 4 can smoothly drive the blanking hopper 4 to shake at the part connected to the mounting frame 41, so that the stamped parts can smoothly slide out of the inside of the device, completing the guiding and blanking of the stamped parts, and thus improving the functionality of the bottom plate 1 during the later use process;

[0035] With the arrangement of the reset spring 23, when the stamping of the sheet is completed and the sliding plate 52 slides upward later, when the connection frame 3 and the telescopic rod 33 at its bottom release the extrusion of the connecting piece 221, the reset spring 23 can smoothly extrude the positioning piece 22 through its own acting force, so that the positioning piece 22 can be smoothly reset and unfolded, which is convenient for the staff to load the sheet and take the stamped sheet later.

[0036] In an embodiment of the present invention, please refer to Figure 2 、 Figure 5 and Figure 6 As shown in, a connection frame 3 is movably connected to the bottom of the support frame 11. An expansion and contraction rod 33 is provided at a position opposite to the connecting piece 221 at the bottom of the connection frame 3. A convex block 35 is provided at the bottom end of the expansion and contraction rod 33. An extrusion spring 34 is sleeved outside the expansion and contraction rod 33. One end of the extrusion spring 34 is fixedly connected to the bottom of the connection frame 3, and the other end of the extrusion spring 34 is fixedly connected to the outer wall of the convex block 35.

[0037] It should be noted that: after the positioning of the sheet to be stamped is completed, when the continuously downward moving sliding plate 52 continuously applies a downward driving force to the connection frame 3 through the convex frame 31, when the downward driving force is greater than the elastic acting force of the extrusion spring 34, the expansion and contraction rod 33 can be smoothly contracted, so that the sliding piece can continuously move downward until the upper die frame 55 at its bottom smoothly abuts against the positioned sheet, and then the air cylinder 53 can be controlled to drive the stamping template 54 to move, so that the stamping template 54 can smoothly pass through the sheet between the upper die frame 55 and the lower die frame 6 for stamping.

[0038] In an embodiment of the present invention, please refer to Figure 2 and Figure 3 As shown in, convex rods 211 that are slidably connected are inserted at positions corresponding to the ends of a plurality of connecting strips 21 inside the connection frame 3. The top end of the convex rod 211 is fixedly connected to the bottom end of the connecting strip 21. A tension spring 32 is sleeved outside the convex rod 211. The top end of the tension spring 32 is fixedly connected to the bottom of the connecting strip 21, and the bottom end of the tension spring 32 is fixedly connected to the top of the connection frame 3.

[0039] It should be noted that: with the arrangement of the convex rod 211, when the connection frame 3 slides downward, the convex rod 211 can smoothly guide the sliding track of the connection frame 3. With the arrangement of the tension spring 32, when the sliding plate 52 releases the extrusion of the connection frame 3 later, the tension spring 32 can smoothly drive the connection frame 3 to reset.

[0040] In an embodiment of the present invention, please refer to Figure 1 、 Figure 5 and Figure 7, vertical rods 5 are provided at the four corners of the top of the bottom plate 1. A sliding plate 52 is sleeved outside the vertical rod 5 and is connected to the vertical rod 5 through a hydraulic cylinder 51 and a support plate at the top of the sliding plate 52. A fixed upper die frame 55 is erected between the bottom of the sliding plate 52 and the corresponding part of the lower die frame 6. A stamping template 54 is inserted inside the upper die frame 55 and is slidably connected, and the stamping template 54 is connected to the bottom of the sliding plate 52 through a cylinder 53. A convex plate 56 is provided on one side wall of the sliding plate 52, and a convex frame 31 is provided below the convex plate 56, and the bottom end of the convex frame 31 is fixedly connected to the top of the connection frame 3.

[0041] It should be noted that: through the setting of the stamping template 54, during later use, the stamping work can be smoothly carried out by driving the stamping template 54 through the cylinder 53. And through the setting of the sliding plate 52, when the hydraulic cylinder 51 works, the components at the bottom can be smoothly driven to move by the sliding plate 52. At the same time, the convex plate 56 on the outer wall can squeeze the convex frame 31 on one side wall of the connection frame 3, and then the connecting piece 221 in the positioning component 2 can be smoothly squeezed through the connecting frame.

[0042] In the embodiment of the present invention, please refer to Figure 1 , a stamping die, including a bottom plate 1, a positioning component 2, a connection frame 3, a lower die frame 6, an upper die frame 55 and a stamping template 54, which are connected in sequence from bottom to top. The bottom plate 1 is the above-mentioned multifunctional bottom plate. Through the setting of the positioning component 2, the stamping plate can be smoothly positioned during use.

[0043] The working principle of the multifunctional bottom plate of the stamping die provided by the present invention is as follows:

[0044] During later use of the device, when the staff installs the positioning component 2 on the bottom plate 1 through the support frame 11, and then places the plate to be stamped on the lower die frame 6, when the hydraulic cylinder 51 is started to drive the sliding plate 52 to move, the sliding plate 52 can smoothly drive the bottom stamping template 54 and the upper die frame 55 to move downward at the same time;

[0045] And during this process, the sliding piece can smoothly squeeze the lower convex frame 31, so that the convex frame 31 can smoothly drive the connection frame 3 to slide downward on the outer wall of the convex rod 211. During the downward sliding of the connection frame 3, the bottom telescopic rod 33 and the convex block 35 can be smoothly driven to move downward. The downward moving convex block 35 can smoothly squeeze the connecting piece 221 in the positioning component 2. At this time, the squeezing piece can drive the connecting part between the corresponding positioning piece 22 and the connecting bar 21 to rotate towards the direction close to the lower die frame 6;

[0046] At this time, the rotating positioning piece 22 can smoothly push the to-be-stamped sheet material protruding outside the lower die frame 6 at the top edge of the lower die frame 6, so that it can smoothly move towards the lower die frame 6 until the outer wall of the positioning piece 22 completely abuts against the outer wall of the lower die frame 6, then the placement and positioning of the to-be-stamped sheet material can be successfully completed without manual positioning of the to-be-stamped sheet material by the staff. Then, the air cylinder 53 can be smoothly controlled to drive the stamping template 54 to stamp the sheet material;

[0047] At this time, the stamped sheet material can smoothly fall into the lower material guiding hopper 44 and then smoothly fall from the material guiding hopper 44 into the lower blanking hopper 4. At this time, the acting force of the stamped sheet material against the blanking hopper 4 can smoothly act on the lower shaking spring 42, so that the shaking spring 42 can smoothly drive the blanking hopper 4 to reciprocally shake at the connection part with the mounting frame 41. Thus, the sheet material located inside the blanking hopper 4 can be smoothly discharged out of the device automatically. Furthermore, when the present base plate 1 is used later, it can position the to-be-stamped sheet material and discharge the stamped sheet material while having a supporting effect. Therefore, the functions of the device in later use can be made more abundant.

[0048] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated here too much.

[0049] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
