Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a structure for quickly adjusting a material relaxation angle outside a die. Background Art

[0002] Stamping dies are special process equipment used to process materials into parts during cold stamping. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts.

[0003] In the stamping production process, the mold adjustment process has an important impact on production efficiency and product quality. The traditional mold adjustment method often requires the mold and the feeder to be adjusted at the same time, which makes the adjustment process cumbersome and inefficient, and it is not easy to achieve precise control. Therefore, a structure for quickly adjusting the material relaxation angle outside the mold is proposed. Utility Model Content

[0006] The lower die base and the lower die are both provided with a slide groove, a guide pin is fixedly inserted into the upper die, and the inner side of the slide groove is slidably connected to a limit column;

[0007] A fixed column is fixed on the outer side of the lower die on one side of the top of the lower die base, and a supporting column is fixed on the outer side of the upper die on one side of the bottom of the upper die base. The fixed column and the supporting column are used to adjust the relaxation angle when the main body of the material is fed.

[0008] Preferably, the inner wall of the slide groove is threadedly connected to a limit block, and a spring is connected between the top of the limit block and the limit column.

[0009] Preferably, a second limiting groove is provided on one side of the top of the limiting column, and a first limiting groove is provided on one side of the material body.

[0013] Preferably, the inner side of the support ring is sleeved on the outer side of the fixing column, and the main body of the material is located between the upper die and the lower die.

[0014] Compared with the prior art, the utility model adopts the above technical solution and has the following technical effects:

[0015] 1. The utility model pulls out the pin to one side and slides the support ring upward so that the support ring is located on the top of the pin, and places the material body at the discharge end of the feeder between the upper die and the lower die.

At this time, the slider of the punch press is manually calibrated, and a support column 3 is fixed on the outer side of the upper die 9 on the bottom side of the upper die seat 2. The fixed column 6 and the support column 3 are used to adjust the relaxation angle when the material body 5 is fed.

[0036] In order to locate and correct errors in time and ensure feeding accuracy, a limit block 12 is threadedly connected to the inner wall of the slide groove 11, and a spring 13 is connected between the top of the limit block 12 and the limit column 14. A second limit groove 17 is opened on one side of the top of the limit column 14, and a first limit groove 15 is opened on one side of the material body 5. The material body 5 at the discharge end of the feeder is placed between the upper mold 9 and the lower mold 10. At this time, the limit column 14 lifts the material body 5 so that the guide pin 16 is inserted into the inner side of the first limit groove 15. At this time, the feeder does not need to clamp the material body 5, and the feeder has met the time requirement for mold relaxation. The outer sides of the guide pins 16 are respectively inserted into the inner sides of the first limit groove 15 and the second limit groove 17.

[0037] In order to improve the efficiency of the mold frame, a pin 4 is inserted into one side of the fixed column 6, a support ring 7 is arranged on the outside of the fixed column 6, a third limiting groove 18 is opened on the outside of the support ring 7, and a clamping ring 8 is clamped on the inside of the third limiting groove 18. The pin 4 is pulled out to make the support ring 7 slide down along the outside of the fixed column 6, and then the pin 4 is inserted into one side of the fixed column 6. At this time, the guide pin 16 is inserted into the inside of the first limiting groove 15 and the second limiting groove 17. At this time, the support column 3 is located at the top of the fixed column 6, and the support column 3 does not contact the end face of the fixed column 6. The inner side of the support ring 7 is sleeved on the outside of the fixed column 6, and the material body 5 is located between the upper mold 9 and the lower mold 10. The feeder can adjust the material thickness of the conveyed material body 5, and the feeder can be adjusted in combination with the mold release time.

[0038] Working principle: when the relaxation angle of the material body 5 needs to be adjusted, the lower die base 1 and the upper die base 2 are respectively installed together with the operating table and hydraulic cylinder of the punching machine, and the punching machine is controlled to separate the upper die 9 and the lower die 10, and then the pin 4 is pulled out to one side, and the support ring 7 is slid upward so that the support ring 7 is located on the top of the pin 4. At this time, the slider of the punching machine is manually adjusted, and then the pin 4 is inserted into one side of the fixed column 6. The punching machine is controlled to make the upper die 9 and the lower die 10 close to each other. At this time, the material body 5 at the discharge end of the feeder is placed between the upper die 9 and the lower die 10. At this time, the limiting column 14 lifts the material body 5, so that the guide pin 16 is inserted into the inner side of the first limiting groove 15. At this time, the feeder does not need to clamp the material body 5, and the feeder has met the time requirement for mold relaxation;

[0039] In the stamping process, the feeder is responsible for accurately feeding the material body 5 into the mold, and the relaxation step is to ensure that the material body 5 will not be stretched or twisted unnecessarily during the feeding process, so as to maintain the flatness and accuracy of the material. When the guide pin is reliably inserted into the guide hole, the relaxation device will separate the upper roller and the lower roller of the feeder, so that the material body 5 is in a relaxed state, and the guide pin can be positioned in time and correct the error to ensure the feeding accuracy;

[0040] Then pull out the pin 4, so that the support ring 7 slides down along the outside of the fixed column 6, and then insert the pin 4 into one side of the fixed column 6. At this time, the guide pin 16 is inserted into the inner side of the first limit groove 15 and the second limit groove 17. At this time, the support column 3 is located at the top of the fixed column 6, and the support column 3 does not contact the end surface of the fixed column 6. Under the pressure of the upper mold 9 and the guide pin 16, the limit column 14 slides inside the slide groove 11, and the limit column 14 compresses the spring 13. At this time, the feeder can adjust the material thickness of the conveying material body 5, and the feeder can be adjusted in combination with the mold release time. By adding support columns 3, pins 4, fixed columns 6, support rings 7, limit columns 14 and guide pins 16 structures to the mold, the mold can be quickly adjusted in conjunction with the feeder during machine adjustment, reducing the time spent on mold adjustment and improving the efficiency of mold mounting. When the mold is relaxed, the feeder does not need to continue clamping the material, allowing the mold to make necessary adjustments or relaxations to ensure the accuracy and stability of the next stamping. The feeder has completed the relaxation operation according to the preset time or conditions. At this time, the mold is already in a suitable relaxed state and is ready for the next stamping.

[0041] In summary, by adding structures such as support columns 3, pins 4, fixed columns 6, support rings 7, limit columns 14 and guide pins 16, the mold can be adjusted more quickly in coordination with the feeder during machine adjustment, greatly reducing the time spent on mold adjustment, thereby improving the efficiency of mold mounting, shortening the production preparation cycle, and allowing the production line to operate more efficiently.
