[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. Stamping and forging belong to plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. 60-70% of the steel in the world is sheet material, most of which is stamped into finished products. The body, chassis, fuel tank, radiator fins of a car, the steam drum of a boiler, the shell of a container, the iron core silicon steel sheets of motors and electrical appliances are all stamped. There are also a large number of stamped parts in products such as instruments and meters, household appliances, bicycles, office machinery, and daily utensils.

The leaking products can easily cause customer complaints. Therefore, an in-die detection mechanism is proposed. Utility Model Content

[0022] Example

[0023] In the prior art, if the punch of the continuous stamping die breaks during the process of stamping parts, it is easy to cause leaking holes on the product, resulting in the product not meeting the processing requirements of the drawing. The outflow of the leaking products is likely to cause customer complaints.

[0024] See also Figure 1-5 , the utility model provides a technical solution: an in-mold detection mechanism comprises a lower mold 2, an upper mold 1 is arranged on the lower mold 2, and a detection component 3 is arranged on the upper mold 1;

[0025] By setting up the detection component 3, it is possible to avoid customer complaints caused by the leakage of punched products; the detection component 3 includes a first insulator 31 and a second insulator 32, the first insulator 31 is installed on the top of the upper mold 1, the second insulator 32 is installed on the top of the first insulator 31, a plurality of deep holes 33 are opened on the top of the first insulator 31, the bottoms of the plurality of deep holes 33 are all provided with first through holes 34, the inside of the first through hole 34 is movably connected with a conductive pin 35, the outer side of the conductive pin 35 is provided with a limit ring 37, the outer side of the conductive pin 35 is movably sleeved with a telescopic spring 36, the top of the second insulator 32 is provided with a plurality of deep holes 33, and the bottom of the plurality of deep holes 33 is provided with a first through hole 34, the inside of the first through hole 34 is movably connected with a conductive pin 35, the outer side of the conductive pin 35 is provided with a limit ring 37, the outer side of the conductive pin 35 is movably sleeved with a telescopic spring 36, and the top of the second insulator 32 is provided with a plurality of deep holes 33, and the bottom of the plurality of deep holes 33 is provided with a first through hole 34, and the inside of the first through hole 34 is movably connected with a conductive pin 35. A plurality of second through holes 38 are provided on the upper part, one end of the conductive pin needle 35 is inserted into the second through hole 38, a conductive plate 39 is provided at the bottom of the first insulator 31, a material strip 4 is provided on the lower mold 2, and a plurality of punching holes 5 are punched on the material strip 4; the equipment performs punching processing on the material strip 4 through the cooperation of the upper mold 1 and the lower mold 2. In this process, the material strip 4 is connected to the positive electrode of the power supply, and the conductive plate 39 is connected to the negative electrode of the power supply. When the product produced by the punching processing of the material strip 4 meets the processing requirements, one end of the conductive pin needle 35 passes through the punching hole 5, the positive and negative electrodes will not be conductive, and the mold operates normally and processes the material strip 4;

[0026] In order to detect the processed products; a plurality of first fixing bolts 6 are installed at the bottom of the conductive plate 39, and the plurality of first fixing bolts 6 pass through the bottom of the conductive plate 39 and are connected to the bottom of the second insulator 32 by threads; when the material strip 4 produces a product that does not meet the processing requirements during the stamping process, one end of the conductive pin needle 35 abuts against the bottom of the material strip 4, and the conductive pin needle 35 moves inside the second through hole 38, the deep hole 33 and the first through hole 34. At this time, the other end of the conductive pin needle 35 abuts against the bottom of the conductive plate 39. Since the conductive plate 39 has a negative pole, the circuit is turned on, and then an alarm is sounded through an external device, causing the equipment to shut down.

[0027] In order to drive the conductive pin 35 to reset; the telescopic spring 36 is located inside the deep hole 33, and the telescopic spring 36 is located below the limit ring 37. The top end of the telescopic spring 36 abuts against the bottom of the limit ring 37, and the bottom end of the telescopic spring 36 abuts against the bottom of the deep hole 33. When a product with missing punching is detected, the conductive pin 35 is squeezed into the second through hole 38, the deep hole 33 and the first through hole 34 and moves. At this time, the telescopic spring 36 is in a compressed state. When the product with missing punching is removed, the conductive pin 35 will be reset under the action of the telescopic spring 36, so that it is convenient to detect the product next time.

[0028] One end of the conductive pin needle 35 extends to the outside of the second through hole 38, and one end of the conductive pin needle 35 passes through the punching hole 5 to complete the product inspection. The top of the second insulator 32 is penetrated by a second fixing bolt 7, and the second fixing bolt 7 is connected to the top of the first insulator 31 through a thread.

[0029] Working principle or structural principle, during the product production process, the equipment cooperates with the upper mold 1 and the lower mold 2 to punch the material strip 4. In this process, by connecting the material strip 4 to the positive pole of the power supply and then connecting the conductive plate 39 to the negative pole of the power supply, when the product produced by the stamping of the material strip 4 meets the processing requirements, one end of the conductive pin needle 35 passes through the punching hole 5, the positive and negative electrodes will not be conductive, the mold operates normally and processes the material strip 4; when the material strip 4 does not meet the processing requirements during the stamping process, one end of the conductive pin needle 35 contacts the bottom of the material strip 4, and the conductive pin needle 35 moves inside the second through hole 38, the deep hole 33 and the first through hole 34. At this time, the other end of the conductive pin needle 35 contacts the bottom of the conductive plate 39. Since the conductive plate 39 has a negative pole, a loop can be formed at this time, and then an alarm is sounded through an external device to stop the equipment, thereby avoiding the leakage of punched products and causing customer complaints.
