Description

Technical Field

[0001] The utility model relates to the technical field of punching dies, in particular to a punching die. Background Art

[0002] Punching dies are a type of stamping dies. A punching die is a die that places the material in the die and then uses a press to punch the material to form holes on the surface of the material.

[0003] Square steel is usually processed with punching dies. Semi-automatic punching equipment is widely used in actual production. The loading and unloading processes of this type of equipment are all manually operated. Semi-automatic punching equipment is used in square steel processing. When the square steel is loaded into the punching die, it is necessary to position it through the pins set on the upper surface of the inner core to ensure that the punched holes are in the set position. When punching different holes on the same surface of the square steel, it is necessary to frequently pull out and plug in the pins to change the position of the square steel. Frequent plugging and unplugging of the pins is a heavy burden on the staff, and the cumbersome process leads to poor punching efficiency.

[0004] Therefore, a punching die is proposed to solve the above problems. Utility Model Content

[0034] Traditional square steel punching dies, such as Figure 6 As shown, a plug hole 14 is provided on the upper surface of the inner core 7 , and a plug pin 15 is provided inside the plug hole 14 . The plug pin 15 can be inserted into the plug hole 14 at different positions to position the square steel 8 .

[0035] See also Figure 1 and Figure 2 , a punching die, comprising:

[0036] The main body comprises a bottom plate 1, the upper surface of which is provided with a fixing seat 2, a supporting vertical plate 3, a supporting block 4 and a threaded hole 6, an inner core 7 is provided at one end of the fixing seat 2, a cover plate 5 is provided at the top end of the supporting vertical plate 3, and the supporting block 4 is located between the supporting vertical plates 3;

[0037] The above structure is the structure of a traditional square steel punching die, in which the inner core 7 and the support block 4 both support the square steel 8, so that the square steel 8 can only move along the direction of the inner core 7;

[0038] The square steel 8 is arranged inside the main body, and the inner core 7 extends to the inside of the square steel 8 .

[0039] like Figure 2 As shown, a mounting frame 11 is arranged at the top of the main body, and a movable hole 12 is arranged at the top of the mounting frame 11. The mounting frame 11 is arranged at the threaded hole 6 by screws. The mounting frame 11 provides a mounting carrier for the positioning member 9, so that the positioning member 9 can move along the direction of the movable hole 12, and the mounting frame 11 is connected and fixed to the base plate 1 under the action of the screws and the threaded hole 6.

[0040] like Figure 2 , Figure 3 as well as Figure 4 As shown, the positioning member 9 is connected to the mounting frame 11 through a fixing nut 13, the positioning member 9 includes a force block 91, a connecting plate 92 is provided at the top of the force block 91, a movable column 93 is provided at the top of the connecting plate 92, the movable column 93 passes through the movable hole 12, the force block 91 includes a first force surface 94, a second force surface 95 and a third force surface 96, the force block 91 is an inclined surface, the second force surface 95 is located between the first force surface 94 and the third force surface 96, and the third force surface 96 is an arc surface;

[0041] The positioning member 9 plays a role in positioning the square steel 8, wherein the first force-bearing surface 94 interacts with the square steel 8 to remind the staff that the positioning position is about to be reached, while the second force-bearing surface 95 plays a role in fixing the square steel, and the third force-bearing surface 96 reminds the user that the positioning position has been reached;

[0042] The return spring 10 is arranged between the positioning member 9 and the mounting bracket 11. The return spring 10 not only resets the positioning member 9, but also provides resistance to remind the user.

[0043] In actual use of this embodiment, after the movable column 93 is inserted into the movable hole 12, the fixing nut 13 is installed on the outside of the movable column 93. At this time, the fixing nut 13 is located above the mounting frame 11. The mounting frame 11 is fixed to the upper surface of the base plate 1 by screws according to actual needs;

[0044] When the square steel 8 is inserted, the square steel 8 contacts the positioning piece 9, and the contact surface between the square steel 8 and the positioning piece 9 is the first force-bearing surface 94. The force of the square steel 8 is increased by the elastic force of the return spring 10 from the simple friction force. At this time, the square steel 8 can be clearly felt to be subjected to resistance, which serves to remind the user that the first positioning point is about to be reached. When the square steel 8 continues to feed to the second force-bearing surface 95, the square steel 8 is only subjected to vertical pressure. At this time, the square steel 8 will not rebound after the user releases his arm;

[0045] Continuous feeding makes the square steel 8 contact the third force-bearing surface 96. The force condition at this time is as follows: Figure 5 As shown in state A, when the square steel 8 contacts the third force-bearing surface 96, the vertical component of force is small, while the horizontal component of force is large. Therefore, if the feeding is to be continued, the resistance is greater than the resistance provided by the first force-bearing surface 94, thereby reminding the user that the first positioning point has been reached and the punching operation can be performed;

[0046] After the first hole is punched, the square steel is continuously fed. The stress conditions during this process are as follows: Figure 5 As shown, from state A to state C, even completely passing through the positioning block 9, so that the positioning block 9 is located above the square steel 8, repeating the above operation to complete the punching operation of the second hole and then pulling out the square steel;

[0047] Compared with the conventional square steel punching die which frequently pulls out and inserts the latch 15, the punching die is simpler and more convenient, and only requires setting the position of the mounting frame 11 in advance.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
