Description

Technical Field

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

[0002] Forging is a processing method that uses a forging machine to apply pressure to a metal blank, extrude and hammer the metal material in a plastic state, so that the physical properties, size and shape of the metal material are gradually formed as required, causing it to undergo plastic deformation to obtain a forging with certain mechanical properties, shape and size.

[0003] Some existing special forgings are used in special equipment such as chemical industry, nuclear power, wind power, aviation, etc. When processing these metal forgings, most of them need to be punched and bent. However, the punching and bending of existing metal forgings are often carried out separately. First, the knife die on the die is cut through the metal material in the die by metal processing pressure on the punching die to form the required holes, and then the punched forging is transferred to the bending die for bending. This processing method not only increases labor costs, but also easily leads to defects in forging products, resulting in a decrease in the yield rate, which greatly limits the production efficiency of the enterprise.

[0025] In the above-described scheme, the die 5 is driven downward by the upper die seat 3. When the die 5 contacts the punch 4, the fixed seats 27 arranged at both ends of the die 5 drive the clamping head 28 to insert downward into the clamping groove 26 opened at the upper end of the swing rod 24. At the same time, the clamping head 28 will push the upper end of the swing rod 24 to move downward, so that the lower end of the swing rod 24 drives the second slider 21 to move outward from the second limiting slide groove 20, so that the upper end of the second slider 21 is separated from the lower end of the first slider 19, so that the support component 22 drives the first slider 19 to move downward along the first limiting slide groove 18; as the die 5 continues to move downward, the outer side of the die 5 will press the floating pad 6 downward, so that the upper end of the punch 4 is inserted upward into the sinking groove 11 and pushes the template 13 to shrink upward, and the forging 17 is punched along the shape of the template 13 through the cooperation of the punch 4 and the template 13. 1 penetrates the template 13 and is inserted downward into the punching hole 10 provided on the punch 4, so that it punches the forging 17, and the pressing punch plates 14 arranged at both ends of the template 13 extend downward and cooperate with the short side of the punch 4 to complete the bending of the forging 17; when the stamping is completed, the upper die seat 3 drives the die 5 to move upward, wherein the clamping head 28 drives the upper end of the swing rod 24 to move upward and disengage from the clamping groove 26, while the upper end of the swing rod 24 moves upward, the lower end of the swing rod 24 will push the second slide block 21 to slide into the second limiting slide groove 20, so that the front end of the second slide block 21 is inserted under the first slide block 19, so that the second slide block 21 pushes the first slide block 19 to move upward, and then the forging 17 processed by the stamping is lifted from the punch 4, so that it is separated from the punch 4, and the demoulding is completed, and the bending edge of the forging 17 will not be deformed during the demoulding process, thereby improving the qualified rate of the finished product.

[0026] See also Figure 3As an embodiment of the utility model, the support assembly 22 includes a support plate 2201, which is fixedly connected to the workbench 1; a push rod 2202 is provided on the support plate 2201, and the lower end of the push rod 2202 passes through the support plate 2201 and is screwed and connected to a limiting nut 2203, wherein the upper end of the push rod 2202 passes through the lower die base 2 and extends upward and is fixedly connected to the bottom of the first slider 19; a support spring 2204 is sleeved on the outer wall of the push rod 2202, and the upper end of the support spring 2204 is fixedly connected to the bottom of the lower die base 2, wherein the lower end of the support spring 2204 is fixedly connected to the support plate 2201.

[0027] In the above scheme, the fixed clamping seat 27 is pushed by the upper die seat 3 to drive the clamping head 28 to move downward and insert it into the clamping groove 26 opened at the upper end of the swing rod 24. At the same time, the clamping head 28 will push the upper end of the swing rod 24 to move downward. Because the middle of the swing rod 24 is movably hinged with the hinge seat 23 through the pin shaft 25, when the upper end of the swing rod 24 moves downward, the lower end of the swing rod 24 drives the second slider 21 to move outward from the second limiting slot 20, so that the upper end of the second slider 21 is separated from the lower end of the first slider 19. At this time, the first slider 19 loses the support of the second slider 21, and the push rod 2202 arranged at the lower end of the first slider 19 will drive the first slider 19 to move downward along the first limiting slot 18 under the elastic force of the support spring 2204, and then the two ends of the punch 4 are connected with the pressing punch. A groove is formed at the corresponding position of the plate 14, which is convenient for the punch plate 14 to extend downward and cooperate with the short side of the punch 4 to complete the bending of the forging 17; when the stamping is completed, the upper die seat 3 drives the die 5 to move upward, wherein the clamping head 28 drives the upper end of the rocker rod 24 to move upward and disengage from the clamping groove 26. While the upper end of the rocker rod 24 moves upward, the lower end of the rocker rod 24 will push the second slider 21 to slide into the second limiting slide groove 20, so that the front end of the second slider 21 is inserted under the first slider 19 and pushes the first slider 19 to move upward, so that the first slider 19 lifts the stamped forging 17 from the punch 4, separates it from the punch 4, and completes the demolding of the forging 17. In addition, the bent edge of the forging 17 will not be deformed during the demolding process, which greatly improves the yield rate of the forging 17.

[0028] Please refer to Figure 3 , Figure 5 As an embodiment of the utility model, a limiting hole 29 is provided on the upper die seat 3, wherein a guide rod 30 is provided in the limiting hole 29; the upper end of the guide rod 30 can move up and down in the limiting hole 29, wherein the end of the guide rod 30 passes through the die 5 downward and is fixedly connected to the template 13; a back pressure spring 31 is provided on the outer wall of the guide rod 30, wherein one end of the back pressure spring 31 is fixedly connected to the bottom of the sinking groove 11, and the other end of the back pressure spring 31 is fixedly connected to the template 13.

[0029] In the above-described scheme, the die 5 is driven to move downward by the upper die seat 3, so that the punch 12 installed in the sinking groove 11 cooperates with the template 13 to punch and cut the forging 17. When the die 5 abuts against the punch 4 and continues to move downward, the back pressure spring 31 sleeved on the outer wall of the guide rod 30 shrinks, and at the same time, the top end of the guide rod 30 moves upward in the limiting hole 29, and drives the template 13 to shrink upward into the sinking groove 11.
