Description

Technical Field

[0001] The utility model relates to the technical field of punching and cutting dies, in particular to a punching and cutting die knife quick adjustment structure. Background Art

[0002] The rough punching cutter currently used is directly embedded in the upper and lower clamping plates of the die frame, and the punching cutter is pressed by the pressing plate to control the punching. During the punching production process, the punching cutter is easily broken at the clamping plate due to the high-speed punching of the punching cutter, and a new punching cutter needs to be made and replaced after the punching cutter breaks. However, because the punching cutter is directly embedded in the upper and lower clamping plates of the die frame, the rough punching die needs to be removed from the machine to replace the new punching cutter. The rough punching die needs to be removed from the machine for repair and production is stopped, which wastes labor time and affects product delivery.

[0003] Moreover, the punching tool has a long blade because it is embedded in the plywood, and the required size of the punching tool processing material is large, the material cost is high, and resources are wasted; the punching tool blade is pressed on the plywood by a pressing plate and is embedded in the upper and lower plywoods tightly, making it difficult to adjust the size and position of the punching tool front, back, left and right; when assembling the punching tool, the punching tool and the punching hole correspond one to one and the punching tool fits the punching hole, resulting in a long mold matching cycle and wasting time; the matching holes between the punching tool and the upper and lower plywood require high precision, and the processing cycle of rough punching mold accessories is long. Utility Model Content

[0004] In order to solve the above technical problems, the utility model designs a punching die and a punching knife quick adjustment structure.

[0005] The utility model adopts the following technical solutions:

[0006] A punching die and punching knife quick adjustment structure comprises an upper clamping plate and a lower clamping plate, wherein both sides of the lower surface of the upper clamping plate and both sides of the upper surface of the lower clamping plate are respectively provided with a locking knife block which can be detachably installed, and the outer side surfaces of the locking knife block are respectively provided with a locking knife groove, and a punching knife can be detachably installed in the locking knife groove so that the punching knife side is locked on the locking knife block.

[0007] Preferably, a mounting hole is transversely arranged on the knife locking block, a threaded mounting hole is correspondingly arranged on the punching knife, and the punching knife is laterally fixed in a knife locking groove on the outer side of the knife locking block by bolts.

[0008] Preferably, the knife locking groove is a rectangular groove.

[0009] Preferably, the knife locking block is fixedly connected to both sides of the lower surface of the upper clamping plate and both sides of the upper surface of the lower clamping plate through bolt holes and bolts respectively.

[0010] Preferably, two guide columns are correspondingly installed on the bottom of the upper clamping plate.

[0011] The beneficial effects of the utility model are as follows: the utility model changes the rough punching cutter into a side locking structure, and the cutter breaks and wears during the punching process, and the cutter can be replaced without lowering the die, the cutter material is saved and the processing requirements are not high, the cutter processing cycle is short, the mold repair cycle is shortened, and the production efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a stereogram of the utility model;

[0013] Figure 2 It is a front view of the utility model;

[0015] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0016] Example: Figure 1 and Figure 2 As shown, a punching die and punching knife quick adjustment structure comprises an upper clamping plate 1 and a lower clamping plate 2, and knife locking blocks 3 are detachably installed on both sides of the lower surface of the upper clamping plate and both sides of the upper surface of the lower clamping plate, and knife locking grooves 5 are respectively opened on the outer sides of the knife locking blocks, and a punching knife 4 is detachably installed in the locking knife groove so that the punching knife side is locked on the knife locking block.

[0017] The knife lock block is transversely provided with a mounting hole 7, and the punching knife is correspondingly provided with a threaded mounting hole 6, and the punching knife is laterally fixed in the knife lock groove on the outer side of the knife lock block by bolts. The knife lock groove is a rectangular parallelepiped groove.

[0018] The knife lock block is fixedly connected to both sides of the lower surface of the upper clamping plate and both sides of the upper surface of the lower clamping plate through bolt holes and bolts. Two guide columns 8 are correspondingly installed at the bottom of the upper clamping plate.

[0019] The punching knife side of the rough punching die of the utility model is locked on the knife locking block and fixed by screws, so the punching knife is simple to replace, which saves time and trouble, shortens the mold repair cycle, saves time, and reduces labor costs.

[0020] The above-described embodiment is only a preferred solution of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solution described in the claims.
