Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

The invention will be further described with reference to the accompanying drawings.

Fig. 1 and 2 are schematic views illustrating an embodiment of the present invention in which the punch of the quick release mechanism is in an operating state (punching) in a closed state.

As shown in the figure, the upper die part at least comprises an upper supporting plate 1, an upper die leg 2, an upper die base 3, an upper backing plate 4, a punch fixing plate 5, a stripper backing plate 6 and a stripper plate 7; the lower die part at least comprises a concave die plate 8, a lower backing plate 9, a lower die base 10, a lower die foot 11 and a lower supporting plate 12.

In an alternative embodiment, the upper supporting plate 1, the upper mold leg 2 and the upper mold base 3 are fixedly connected by a plurality of bolts (see bolts 22 in fig. 3). The upper backing plate 4 and the punch fixing plate 5 are accurately positioned by positioning pins (see positioning pins 27 in fig. 3) and then fixed on the upper die holder 3 by bolts (see bolts 29 in fig. 3). In an alternative embodiment, the intermeshing plates 16 are embedded in the upper shim plate 4, and the intermeshing plates 16 may optionally be heat treated hard stock, thereby reducing wear between themselves and the intermeshing plates 15 during the die tooling. In an alternative embodiment, the engaging plate 15 is embedded in the upper die base 3 and connected with the engaging plate connecting plate 20 through bolts (see bolts 34 in fig. 3), and the engaging plate 15 can be selected to be a heat-treated hard material, so that the abrasion between the engaging plate 16 and the engaging plate 15 during the die machining process is reduced. The punch 17 is fixed below the engaging plate 16 in a manner that the punch 17 is embedded in the punch fixing plate 5 and then pressed by the engaging plate 16, so that the punch 17 can prevent the punch 17 from moving upwards when the punch 17 punches downwards, thereby achieving the purpose of punching.

In an alternative embodiment, the supporting base 18 is connected to the upper die base 3 by bolts (see fig. 3, bolt 37), and the stripper plate 6 and the stripper plate 7 are fixedly connected by bolts (see fig. 3, bolt 30) and connected to the punch fixing plate 5 by the contour sleeve assembly 23. In an alternative embodiment, the cavity plate 8, the lower backing plate 9 and the lower die holder 10 are fixed by bolts (see bolts 31 in fig. 3) and accurately positioned by positioning pins (see positioning pins 36 in fig. 3). The lower die base 10 is fixedly connected with the lower die leg 11 through a bolt (see a bolt 32 in fig. 3), and the lower die leg 11 is fixedly connected with the lower supporting plate 12 through a bolt (see a bolt 33 in fig. 3).

Fig. 3 and 4 are schematic views illustrating an embodiment of the present invention in which the mold is closed and the punch of the quick release mechanism is not in operation (not punching).

As shown in the figure, the upper die part and the lower die part are precisely guided and positioned by the inner guide post 24, the inner guide sleeve 25, the inner guide sleeve 35 and the outer guide post 26.

When any one of the stamping dies for the product common mode quick-change mechanism works, the upper die part of the stamping die is fixed on the upper table surface of the punch press, and the lower die part of the stamping die is fixed on the lower table surface of the punch press.

Specifically, when it is desired to produce a product hole with a quick release mechanism control, i.e., during the process of changing a punch in the quick release mechanism from an inactive state to an active state (as shown in fig. 1 or 2), it is only necessary to rotate the transmission rod clockwise (see the transmission rod 19 in fig. 1). At this time, the transmission rod 19 drives the engaging plate connecting plate (see the engaging plate connecting plate 20 in fig. 1) to move in a direction away from the supporting base (see the supporting base 18 in fig. 1), and since the engaging plate (see the engaging plate 15 in fig. 1) is connected with the engaging plate connecting plate 20, the engaging plate 15 moves in the same direction as the engaging plate connecting plate 20. When the engaging plate connecting plate 20 is moved to be flush with the die holder side surface, the convex surfaces of the engaging plate 15 and the engaging plate 16 are brought into contact with each other. A punch 17 engaging the underside of the plate 16 in the closed condition of the die will punch the desired hole through the strip of material.

When it is not necessary to produce a product hole with a quick release mechanism control, i.e. when the punch is switched from the working state to the non-working state (as shown in fig. 3 or 4), it is only necessary to rotate the transmission rod counterclockwise (see the transmission rod 19 in fig. 1). The support seat (see the support seat 18 in fig. 1) now functions both to support the movement of the transmission rod 19 and to prevent the overtravel movement of the engagement plate (see the engagement plate 15 in fig. 1). That is, the support 18 is fixed relative to the upper die bed 3 and moves when the support link 19 rotates, and because the support link 19 is connected to the gusset plate 20, the gusset plate 20 follows the movement as well, and because the gusset plate 20 is fixed to the gusset plate 15, the gusset plate 15 follows the movement as well. Since the support base 18 is outside the engaging plate 15 and covers the engaging plate 15, the moving stroke of the engaging plate 15 is limited, thereby serving to prevent the over-travel of the engaging plate 15. When the engaging plate 15 is in contact with the support seat 18, it means that the recessed surfaces of the engaging plate 15 and the engaging plate 16 have come into contact. (during the movement of the engaging plate 15, as the engaging plate 16 is stopped by the equal height screws 21, they will move upwards under the action of the spring 14. thus, the engaging plate 16 contacts the groove surface of the engaging plate 15.) at this time, the engaging plate 16 and the punch controlled by the engaging plate 16 have a certain movement space, and the lower punch 17 can not pass through the material belt under the condition that the die is closed, thereby achieving the purpose of no punching.

From the operation mechanism of the invention, the meshing plate connecting plate 20 can be driven by rotating the transmission rod 19 so as to drive the meshing plate 16 to rotate up and down, and due to the limiting effect of the equal-height screw 21 and the equal-height assembly 23, the meshing plate connecting plate 20 and the meshing plate 15 can move in the same direction, so that the punch 17 controlled by the meshing plate 16 is driven to realize the separation from the material belt or punching through the material belt (without punching or punching). This allows for non-punching (or replacement with punching of other shapes) of products for which punching is not desired. The invention provides a method for quickly replacing the punch, and the movable space of the punch is adjusted to be far away from the material belt or punch through the material belt. For products requiring a plurality of punches, centralized distribution of the punches of the products can be realized by sharing one transmission mechanism, and distributed distribution of the punches can be realized by using a plurality of transmission mechanisms. The purpose of the paired arrangement of the engaging plate 15 and the engaging plate 16 is to control the punch not to punch and punch by using the closed and open and closed states of the engaging teeth, respectively. The height of the space occupied by the engaging plate 15 and the engaging plate 16 in the engaging state is different from that occupied by the non-engaging state, the punch is fixed and loosened by utilizing the height difference of the space, the height of the space occupied by the engaging plate 15 and the engaging plate 16 is small when the engaging plate is engaged, the punch can move upwards when receiving blanking force so as not to punch, the height of the space occupied by the engaging plate 15 and the engaging plate 16 is large when the non-engaging plate is not engaged, the punch can be firmly pressed below the engaging plate 16, and the punch can not move upwards even if the punch receives the blanking force, so that the purpose of punching is achieved. When the punch is broken, the die needs to be disassembled for replacement, and when the punch is not used, the punch does not need to be taken out. The spring 28 is used for providing a pressing force for the stripper plate 7 before punching, so that the stripper plate 7 presses the material in advance for punching, and further, the force generated by the spring 28 is used for providing a discharging force after punching, so that the stripper plate 7 separates the punch 17 from the product, and an operator can take the product out of the die conveniently.

The connection of the parts shown in fig. 5 and 6 is identical to that shown in fig. 3 and 4, except that the mold is in an open state, in which the stripper plate (see fig. 1, stripper plate 6) and the punch retaining plate (see fig. 1, punch retaining plate 5) are changed from the contact state of fig. 3 to the non-contact state by the elastic force of the spring (see fig. 3, spring 28).

The utility model has the advantages of the time that the mould needs frequent dismouting to consume when reducing product transform production, the smooth completion product production change under the condition of punch press is not pulled down to the mould, its simple structure, low cost, stamping efficiency is high, the error rate is low. Furthermore, automatic production is realized, and the production cost is reduced.
