Detailed Description

The commemorative coin forming die 3 clamping protection device in the figure comprises a clamping mechanism 1 and a protection mechanism 2, wherein the clamping mechanism 1 and the protection mechanism 2 are mutually independent, the clamping mechanism 1 is used for clamping and fixing the forming die 3, the protection mechanism 2 is used for accommodating the forming die 3, and in practical application, other parts can be added, so that the comprehensive performance of the protection device can be improved.

The clamping device 1 in this case simulates the structure of a clamp, and in order to enable the clamping device 1 to clamp the cylindrical forming die 3, the clamping device 1 in this case is provided with a cylindrical clamping end 11 and a handle end 12. Wherein the cylindrical clamping end 11 is designed to be hollow, so that the hollow position is used for freeing space for placing the forming die 3 and sleeving the arc-shaped side surface of the forming die 3 through the screw 4. The handle end 12 is used for hand-held operation, so that the forming die 3 can be carried and the forming die 3 can be positioned to play a role in limiting. The cylindrical holding end 11 is designed into a hollow annular structure to form an annular arm 111, the inner diameter of the annular arm 111 is larger than the inner diameter of the forming die 3, the height of the annular arm 111 is smaller than the height of the forming die 3, and the annular arm 111 adopts a drilling process to uniformly drill four screw holes 4 penetrating through the arm body, so that the screws 4 and the head part with the external thread of the handle end 12 can be installed. Wherein the screw 4 is screwed from outside to inside, the head of the screw 4 is arranged outside the annular arm 111, thus the entering amount of the screw 4 entering the annular arm 111 is movably adjusted, and the forming die 3 with different inner diameters can be adapted. Two or three screws 4 can be adopted, and when two screws are adopted, two screws are also adopted and are symmetrically arranged at the handle ends 12; when there are three screws 4, there is one handle end 12. The handle end 12 is integrally Y-shaped and provided with a V-shaped groove, the innermost end of the V-shaped groove is provided with a positioning hole 121, and one side of the Y-shaped groove is provided with an external thread, so that after the clamping mechanism 1 is placed, the clamping mechanism 1 can be positioned through the positioning hole 121 and the positioning column 52, and the position of the forming die 3 is ensured to be placed correctly. In order to facilitate holding the handle end 12, a rubber sleeve can be sleeved on the handle end 12, so that the holding end can conveniently clamp the forming die 3. In order to guarantee the clamping accuracy, the screws 4 are at the same height on the annular arm 111. In practical application, the number of the screws 4 and the handle ends 12 can be adjusted as required, and meanwhile, the V-shaped groove can be designed into a U-shaped groove, so long as the requirement that the handle ends 12 and the screws 4 are aligned with the center of the clamping end 11, the forming die 3 is clamped and conveniently held by hands is met.

In the present invention, the protection mechanism 2 is optimized from an original structure having the same overall strength into two structures having different strengths, i.e., a fixed mold 21 and a protection mold 22, which are both hollow and annular. Wherein the inner diameter of the protection die 22 is larger than the inner diameter of the fixed die 21 so as to enable the fixed die 21 to be arranged in the protection die 22, the protection die 22 and the fixed die 21 are matched together in a traditional extrusion interference mode, the strength of the protection die 22 is larger than that of the fixed die 21, and the strength of the protection die 22 is designed to be 2 times of that of the fixed die 21 in the scheme, so that the protection die 22 is prevented from being cracked in the extrusion process. The protection die 22 is attached to a press die 51 of a press machine having a positioning post 52, and the positioning post 52 is held in position with a positioning hole 121 in the V-groove. The commemorative coin forming die 3 is fixed on a base 7, meanwhile, the base 7 is fixed on a bottom plate 53, a guide post 54 is arranged between the stamping die 51 and the bottom plate 53, and a spring is sleeved on the guide post 54, so that the stamping die 51 is reset under the action of the spring after stamping work is finished. The top of commemorative coin moulded die 3 has the drop with the top of fixed mould 21 and forms commemorative coin and place chamber 6, is convenient for place commemorative coin blank like this, because mould 55 directly over commemorative coin moulded die 3, should go up mould 55 and fix on a roof 56, this roof 56 and guide post 54 cooperation, go up mould 55 like this and can place the commemorative coin blank 8 in the chamber 6 to being in commemorative coin and carry out the punching press.
