Description

Technical Field

[0001] The invention belongs to the technical field of die cutting, and in particular relates to a QDC module with movable fine adjustment of guide pins and a die cutting device. Background Art

[0002] QDC mold is a combination of hardware mold and etching mold or engraving mold. This type of mold can realize the process of removing small hole waste and product shape in one die-cutting when processing die-cut products. The mold is stable during production and processing, and the mold life is relatively long. It can process some products with thick materials and high hardness. The mold has high dimensional accuracy and performs particularly well in saving labor. The waste removal effect is 100%. It is generally used in the first process of die-cutting processing to punch waste parts and sleeve holes and inner hole waste.

[0003] QDC die base is a new type of die developed in recent years and used in die-cutting process. This type of die is mainly used with metal die, etching die or engraving die. It can realize the waste removal of completely closed holes inside the product and die-cutting of the shape. The waste removal effect is 100%. This type of die is stable during production and processing, the die life is long, the die can be repeatedly repaired, and the die-cutting effect of small hole sets is good.

[0004] Ordinary QDC die bases are only designed for locating hole punching and waste material, without synchronously designing positioning guide pins, and cannot realize punching and guiding at the same time. They are only suitable for making sheet materials. For coil materials, a single die base with guide pins needs to be designed.

[0005] The jump distance is fixed between the positioning holes and cannot be adjusted, so it is not universal.

[0006] Please refer to the QDC mold base of the existing technology Figure 3 and Figure 4 As shown, a punch 200 is arranged on the upper die set and a punch hole 100 is arranged on the lower die set. When the punch hole 100 punches out the hole of the material, the punch 200 on the upper die set pushes the waste into the lower die set. Summary of the invention

[0007] The purpose of the present invention is to overcome the defects of the prior art and provide a QDC module and a die-cutting device with movable fine-adjustable guide pins.

[0008] The purpose of the present invention can be achieved by the following technical solutions:

[0009] The present invention provides a QDC module with a movable fine-adjustable guide post, which is used for punching a workpiece. The QDC module comprises:

[0010] An upper die set, comprising an upper die set body, a plurality of punches disposed on the upper die set body, and a plurality of guide pillars disposed on the upper die set body;

[0011] A lower die set, comprising a lower die set body, a plurality of punch sleeve holes arranged on the lower die set body and opposite to the punch, and a sleeve groove located at one end of the punch sleeve hole and matching with the guide column;

[0012] Wherein, the guide pillar is detachably connected to the upper mold assembly body;

[0013] During die cutting, the upper die set cuts downward, the punch and the punch sleeve punch out the material positioning hole, the material jumps, and the guide pin is pushed into the material positioning hole and the sleeve groove in sequence to realize the positioning of the material.

[0014] Furthermore, the punch sleeve hole is in the shape of a hollow cylinder, the lower die set also includes a waste cavity arranged inside the lower die set body, and the punch sleeve hole is connected to the waste cavity.

[0015] Furthermore, the punch is cylindrical, and the maximum diameter of the circular hole of the punch sleeve is at least larger than the maximum diameter of the punch.

[0016] Furthermore, the sleeve groove is a rectangular groove, and the four corners of the rectangular groove are arranged to be rounded.

[0017] Furthermore, the guide pillars are arranged in two rows and in parallel on the upper die set body, two sleeve slots are provided and arranged in parallel, and the punch sleeve holes are arranged in two rows and in parallel on the upper die set body.

[0018] Furthermore, the guide post is cylindrical and the maximum diameter of the guide post is at least smaller than the width of the sleeve groove.

[0019] Furthermore, the length of the sleeve groove is at least longer than the length of some of the punch sleeve holes.

[0020] Furthermore, the upper mold assembly also includes a guide post installation groove provided on the upper mold assembly body, a plurality of threaded holes are arranged in the guide post installation groove, and the guide posts are threadedly connected to the threaded holes.

[0021] Furthermore, the lower die set also includes a plurality of mounting blocks arranged on the lower die set body, and the punch sleeve hole and the sleeve groove are arranged on the mounting blocks.

[0022] The present invention also provides a die-cutting device, comprising:

[0023] A feeding assembly, comprising a material feeding roller and a material feeding roller driving motor drivingly connected to the material feeding roller;

[0024] A die-cutting assembly, comprising a punching machine connected to the material feed roller, and a QDC module with a movable fine-adjustable guide post as described above is installed on the punching machine; and

[0025] The finished product winding assembly comprises a finished product winding roller connected to the punching machine and a finished product winding driving motor connected to the finished product winding transmission.

[0026] The working principle of the present invention is as follows:

[0027] Two rows of guide posts are arranged on the upper die body, and two rows of top wastes are arranged beside the two rows of guide posts. A guide post installation groove is fixed on the upper die body, and a thread is arranged inside the groove, and the guide post is installed in the guide post installation groove. Two rows of mounting blocks are arranged on the lower die body, and punch sleeve holes and sleeve slots located beside the punch sleeve holes are installed on the mounting blocks.

[0028] The guide pin is parallel to the sleeve groove, and the punch sleeve hole corresponds to the punch one by one.

[0029] When die-cutting, select the punch hole, the number and position of the guide pins, and select the number and position of the punches corresponding to the punch hole for die-cutting.

[0030] The material passes through the lower die set, and the punch on the upper die set and the punch sleeve on the lower die set punch out the material hole. At this time, the punch of the upper die set pushes the material waste into the waste cavity at the same time. It should be noted that a waste discharge hole is opened on one side of the lower die set body. After the waste cavity is full, the material waste can be removed by connecting a vacuum cleaner to the waste discharge hole. After the punch sleeve punches out the material hole, the material jumps, and the guide column pushes into the material hole punched out by the punch sleeve and extends into the sleeve slot. It should be noted that since the length of the sleeve slot is greater than the sum of the lengths of all punch sleeves, the guide columns installed according to the different punch sleeves can all extend into the sleeve slot.

[0031] It should be noted that, since the punch needs to push the waste material punched out by the punch sleeve hole into the waste material cavity, the diameter of the punch is smaller than the diameter of the circular hole of the punch sleeve hole.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] (1) The present application solves the defect that ordinary mold bases can only punch holes but cannot simultaneously punch and set holes, thereby improving the process yield and saving process and mold costs.

[0034] (2) The present application solves the problem of the universality of the die base by setting a detachable punch hole and a detachable guide pin. Under different jump distance settings, the positioning hole function of the die set can be achieved by setting different guide pins, thereby improving the usability of the die base and saving the cost of the QDC die base.
