Description

Technical Field

[0001] The utility model belongs to the technical field of pre-cutting products by punching dies, and in particular relates to a device for pre-cutting products by punching dies. Background Art

[0002] When the hardware is die-cast in the mold, the hardware is pre-cut to facilitate the removal of the formed product from the hardware. Specifically, a pre-cut shape is profiled and ground on a hexahedral high-speed steel block, and the part is loaded into the die. When the stamping die is loaded into the punch press and the upper and lower dies are closed, the pre-cut profile parts of the upper and lower dies will punch out the pre-cut shape on the product strip.

[0003] However, the pre-cut parts of the imitation are very easy to wear, and because the imitation part is small, the parts are easy to break. In addition, the manufacturing cost of the pre-cut parts is high and the manufacturing cycle is long, which causes the problem that the conventional pre-cut parts need to be replaced as a whole after the vulnerable parts break.

[0004] Therefore, we propose a device for pre-cutting the product by the stamping die to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that the conventional pre-cut parts need to be replaced as a whole after the vulnerable parts are broken, and proposes a device for pre-cutting products by a punching die.

When the insert is damaged, the damaged insert is pushed out and then replaced with a new insert, and the replacement of vulnerable parts is achieved through a simple structure, avoiding the need for overall re-manufacturing, facilitating replacement and reducing waste, thereby improving practicality.

[0008] Preferably, the clamping mechanism comprises a receiving slot provided on the pre-breaking seat, the receiving slot is connected to the groove, a telescopic rod is fixedly connected to the bottom of the receiving slot, and a protrusion is fixedly connected to one end of the telescopic rod away from the bottom of the receiving slot. The clamping mechanism can be provided so that the telescopic rod can be contracted by pressing the protrusion, and then can be removed from the pressing plate, so that the pressing plate releases the insert, which is convenient for locking or unlocking the insert.

[0009] Preferably, an elastic spring is sleeved on the outer wall of the telescopic rod, and the two ends of the elastic spring are respectively fixedly connected to the outer wall of the protrusion and the outer wall of one end of the telescopic rod close to the receiving groove. The elastic spring ensures that the pressing plate can stably fix the insert without external force.

[0010] Preferably, the fixing plate and the pressing plate are provided with a first limiting hole and a second limiting hole respectively, the first limiting hole and the second limiting hole are respectively adapted to the protrusion, and the protrusion is clamped in the first limiting hole and the second limiting hole.

[0024] The technical solutions in the utility model embodiments will be described clearly and completely below in conjunction with the drawings in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, rather than all of the embodiments.

[0025] See also Figures 1 to 6 A device for pre-cutting a product by a stamping die comprises an insert 1 and a pre-cutting seat 2. The pre-cutting seat 2 is provided with an insert groove 4, in which the insert 1 is inserted, wherein the insert 1 is adapted to the insert groove 4, and the insert 1 can protrude to the outside of the pre-cutting seat 2. When the insert 1 is damaged, the damaged insert 1 is pushed out and then replaced with a new insert 1. The replacement of vulnerable parts can be achieved through a simple structure, and overall re-manufacturing can be avoided, which is convenient for replacement and reduces waste, thereby improving practicality.

[0026] A groove 3 is provided on the pre-breaking seat 2, and a fixing plate 5 is fixedly connected to the inner wall of the groove 3. By arranging the pressing plate 6 between the fixing plate 5 and the bottom of the groove 3, the pressing plate 6 can be limited, so that the pressing plate 6 can only slide along the direction of the groove 3. When the telescopic rod 10 and the protrusion 11 limit the pressing plate 6 through the first limiting hole 7 and the second limiting hole 8, the pressing plate 6 cannot move, thereby achieving the fixing of the insert 1 by the pressing block on the pressing plate 6.

[0027] The pre-breaking seat 2 and the fixed plate 5 are connected with a compression piece 6 through a clamping mechanism. The compression piece 6 includes a sheet body and a compression block. The end face of the compression block fits with the end face of the insert block 1. The end face of the compression block is inclined. The compression block and the sheet body are fixedly connected as a whole. The integral molding of the sheet body and the compression block improves the stability of the compression piece 6 and avoids the phenomenon that the compression piece 6 is easily broken.

[0028] The compression plate 6 is inserted between the bottom of the groove 3 and the fixing plate 5. The fixing plate 5 and the pre-breaking seat 2 are integrally formed. The integral forming of the fixing plate 5 and the pre-breaking seat 2 improves the overall firmness of the device. The fixing plate 5 and the compression plate 6 are respectively provided with a first limiting hole 7 and a second limiting hole 8. The centers of the first limiting hole 7, the second limiting hole 8 and the receiving groove 9 are located on the same straight line. The three are correspondingly arranged. By having the three located on the same straight line, the compression plate 6 can be pulled out of the groove 3 when the protrusion 11 is pressed.

[0029] The first limiting hole 7 and the second limiting hole 8 are respectively matched with the protrusion 11, and the protrusion 11 is clamped in the first limiting hole 7 and the second limiting hole 8. The clamping mechanism includes a receiving groove 9 opened on the pre-breaking seat 2, and the receiving groove 9 is connected to the groove 3. A telescopic rod 10 is fixedly connected to the bottom of the receiving groove 9, and the end of the telescopic rod 10 away from the bottom of the receiving groove 9 is fixedly connected to the protrusion 11. The outer wall of the telescopic rod 10 is sleeved with an elastic spring 12, and the two ends of the elastic spring 12 are respectively fixedly connected to the outer wall of the protrusion 11 and the outer wall of the end of the telescopic rod 10 close to the receiving groove 9. By providing the elastic spring 12, the elastic spring 12 can stably control the protrusion 11 in the first limiting hole 7 and the second limiting hole 8 without the action of external force, thereby realizing the restriction of the position of the compression plate 6, making the compression plate 6 unable to move, and then the compression plate 6 fixes the end face of the insert 1, thereby improving the stability of the device.

[0030] Working principle: when the insert 1 is damaged, the protrusion 11 is pressed, and the protrusion 11 drives the telescopic rod 10 to contract under the action of external force, so that the protrusion 11 enters the storage groove 9. At the same time, the compression piece 6 is drawn outward. After the compression piece 6 moves outward, the insert 1 loses its restriction, and the damaged insert 1 can be pushed out, and then a new insert 1 is replaced. After the new insert 1 is replaced, the compression piece 6 is restored to its original position and the new insert 1 can be fixed again. The replacement of vulnerable parts can be achieved through a simple structure, avoiding overall re-manufacturing, facilitating replacement and reducing waste.

[0031] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited to it. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the utility model according to the technical scheme and utility model concept of the utility model, which should be covered by the protection scope of the utility model.

[0032] The description briefly mentions the application direction of the utility model for the prior art that is known to those skilled in the art and has not been changed, and combines it with the utility model to form a complete technology; the description avoids over-popularizing the technology familiar to those skilled in the art, and is used to assist those skilled in the art to quickly understand the main content of the utility model.
