[0001] The utility model relates to the technical field of blanking dies, in particular to a blanking die step fast positioning structure. Background Art

[0002] In the manufacturing process of progressive blanking dies, in order to ensure the accuracy of the part feeding pitch, we usually pre-punch holes in the middle of the first process of the material strip, and then use relevant standard parts as pins to insert into the pre-punched holes in the second process. Finally, the fitter judges the accuracy of the feeding pitch by whether the pre-punched holes in the second process are deformed. Therefore, the demand for an adjustable blanking die pitch sensing positioning structure is growing.

[0003] At present, in order to position the pitch of the sheet, some existing technologies also provide a positioning structure in the blanking die. For example, Chinese patent announcement No. "CN209020977U" discloses an adjustable blanking die pitch sensing positioning structure, which includes a material belt, a transmission seat and a transmission frame. A special-shaped punching hole is opened on one side below the material belt, and an induction positioning block is arranged in the special-shaped punching hole.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 As an embodiment of the utility model, a blanking die step quick positioning structure is specifically disclosed, which is installed above the lower die unit 1, and the specific positioning structure includes a guide component 2 and a detection component 3;

[0023] The guide components 2 are provided with two and are respectively located on both sides of the detection component 3, wherein the guide components 2 are adjusted and fixed on the lower mold unit 1 by the adjustment component 4;

[0024] The detection component 3 includes a telescopic part 31 and a detection part 32 . The detection part 32 is used to detect the movement of the telescopic part 31 to achieve step positioning.

[0025] In some embodiments, the guide assembly 2 in the utility model includes a guide seat 21, and a guide surface 22 is provided on the side of the guide seat 21 facing the lower mold unit 1, and the guide surface 22 is used to guide the sheet. Specifically, the guide surface 22 is an inclined surface, and the guide seat 21 is fixed to the lower mold unit 1 through a locking member. Preferably, the locking member described in this embodiment is set as a bolt.

[0026] On the basis of the above embodiments, the adjustment component 4 in the utility model includes a plurality of limit columns 41 fixed on the lower mold unit 1, the axis lines of the plurality of limit columns 41 are on a plane, and the plane is horizontal with the side surface of the guide seat 21, and a plurality of gaskets 42 are placed between the limit columns 41 and the guide seat 21, wherein a step-shaped I-shaped groove 23 is opened at the upper end of the guide seat 21, and the locking member is arranged in the I-shaped groove 23.

[0027] Specifically, during the initial installation process, the required number of gaskets 42 can be installed according to the required installation position of the guide seat 21. The gaskets 42 are installed between the limit columns 41 and the guide seat 21 to achieve the positioning of the position of the guide seat 21. Thereafter, the guide seat 21 can be fixed by locking the position of the guide seat 21 with a locked locking piece.

[0028] Specifically, the telescopic portion 31 in the present embodiment includes a fixing seat 311 mounted on the lower mold unit 1 , a positioning rod 312 is movably inserted into the fixing seat 311 , and an elastic member 313 is provided between the positioning rod 312 and the fixing seat 311 .

[0029] On the basis of the above-mentioned embodiment, a recessed portion 315 is provided at the upper end of the positioning rod 312 in the utility model, a protrusion 314 located in the recessed portion 315 is fixed to the inner side of the fixing seat 311, and the elastic member 313 is provided between the protrusion 314 and the recessed portion 315, wherein the elastic member 313 described in the utility model is a spring, and the spring is designed to maintain the initial position of the positioning rod 312, so as to achieve the effect of automatic reset after separation from the sheet.

The sensor 322 is configured as a proximity switch. In addition, the proximity switch is used to connect to the control unit to determine the sheet pitch positioning. The sensor 322 is used to detect the positioning rod 312.

[0031] During specific operation, the sheet enters along the upper part of the lower mold unit 1 while keeping the side of the sheet in contact with the side of the guide seat 21. During the movement of the sheet, it will conflict with the retraction of the positioning rod 312. At this time, the sensor 322 detects the sheet entry signal. When the positioning rod 312 is engaged with the pre-punched hole on the sheet, under the action of the elastic member 313, the positioning rod 312 extends out and is engaged in the pre-punched hole. The sensor 322 loses the positioning rod 312 signal, and it is determined that the current sheet pitch positioning is completed.

[0032] In summary, the utility model adopts the cooperation of the telescopic part 31 and the detection part 32 to realize the rapid detection and judgment of the entry step of the sheet, so as to improve the positioning efficiency of the sheet during processing.
