[0030] Embodiment 1:

[0031] See also Figure 1-5 The utility model describes the above technical solution in detail through the following embodiments:

[0032] A hydraulic punching device for an automobile production line, comprising:

[0033] The stamping assembly 1 comprises a hydraulic cylinder 13 , a workbench 14 is arranged directly below the hydraulic cylinder 13 , and a die assembly 2 is arranged between the workbench 14 and the hydraulic cylinder 13 .

[0034] The stamping assembly 1 also includes a base 11, a workbench 14 is fixedly installed on the front side of the top of the base 11 by bolts, a frame 12 is welded and installed on the rear side of the top of the base 11, a hydraulic cylinder 13 is fixedly installed on the front side of the top of the frame 12 by bolts, the hydraulic cylinder 13 is installed vertically, and the piston rod of the hydraulic cylinder 13 is vertically downward.

[0035] A slag discharge port 16 is provided through the middle of the workbench 14 , and the slag discharge port 16 is located directly below the hydraulic cylinder 13 . A guide groove 15 is provided on the top surface of the workbench 14 .

[0036] The slag discharge port 16 extends from the top surface of the base 11 to the middle of the front side surface of the base 11 .

[0037] The mold assembly 2 includes a top mold 21 and a bottom mold 22. The top mold 21 is threadedly mounted on the top of the piston rod of the hydraulic cylinder 13, and the bottom mold 22 is fixedly mounted on the top surface of the workbench 14. The top surface of the bottom mold 22 is used to place materials. The top mold 21 can move downward under the drive of the piston rod of the hydraulic cylinder 13 to punch the materials.

[0038] By controlling the piston rod of the hydraulic cylinder 13 to extend or retract, the top die 21 can be driven down or up. The top die 21 cooperates with the bottom die 22 to punch holes in the material. Different top die 21 and bottom die 22 can be replaced according to the required holes.

[0039] A plurality of guide blocks 24 are welded to the bottom surface of the bottom mold 22 . The guide blocks 24 are engaged with the guide grooves 15 . A forming hole 23 is provided at the center of the bottom mold 22 . The forming hole 23 is located just above the slag discharge port 16 .

[0040] The guide block 24 can slide along the guide groove 15, and the guide groove 15 is used to prevent the guide block 24 from moving upward. The four corners of the top surface of the bottom mold 22 are threadedly connected with fixing bolts 26, and the fixing bolts 26 penetrate the bottom mold 22 and the workbench 14 and are threadedly connected. The fixing bolts 26 are used to prevent the bottom mold 22 from sliding forward and backward.

[0041] The outer diameter of the top die 21 is slightly smaller than the inner diameter of the forming hole 23 . The top die 21 and the forming hole 23 cooperate to apply shear force to the material, thereby punching the material. The waste generated by punching can be discharged from the forming hole 23 , fall to the slag discharge port 16 , and then discharged from the slag discharge port 16 .

[0042] A plurality of second guide grooves 25 are disposed on the top surface of the bottom mold 22 and on both sides of the molding hole 23 .

[0043] The second guide groove 25 is a T-shaped groove, and the second guide groove 25 is transverse, and the second guide groove 25 does not penetrate the bottom mold 22 .

[0044] The positioning component 3 includes two wedge-shaped limiting blocks 32. The wedge-shaped limiting blocks 32 are symmetrically and slidably mounted on the top surface of the bottom die 22 through a pressurizing component. The pressurizing component is used to apply a pressure to the wedge-shaped limiting blocks 32 towards the center of the bottom die 22. The opposite sides of the wedge-shaped limiting blocks 32 are inclined surfaces, which are inclined downward, and the edges of the material abut against the inclined surfaces of the wedge-shaped limiting blocks 32. The pressurizing component is located in the second guiding groove 25.

[0045] The wedge-shaped limiting blocks 32 are in the shape of '丿'. The heads of the two wedge-shaped limiting blocks 32 are parallel to each other, and the tails of the two wedge-shaped limiting blocks 32 are bent outward. The material is inserted into the space between the tails of the two wedge-shaped limiting blocks 32.

[0046] Several second guiding blocks 33 are welded to the bottom surface of the wedge-shaped limiting blocks 32. The second guiding blocks 33 are slidably connected and clamped with the second guiding groove 25, and the pressurizing component is located outside the second guiding blocks 33.

[0047] The second guiding groove 25 can prevent the second guiding blocks 33 from moving upward, thereby preventing the wedge-shaped limiting blocks 32 from moving upward.

[0048] The pressurizing component includes a guiding column fixing block 35. The guiding column fixing block 35 is fixedly mounted at the end of the second guiding groove 25 through bolts. A guiding column 34 is welded to the center of the side of the guiding column fixing block 35 facing the second guiding blocks 33, and the guiding column 34 penetrates through the second guiding blocks 33.

[0049] The guiding column 34 is clamped with the bottom die 22 after passing through the second guiding blocks 33, and the second guiding blocks 33 can slide along the guiding column 34. The guiding column fixing block 35 is used to limit the sliding distance of the second guiding blocks 33.

[0050] An adjusting spring 36 is sleeved on the guiding column 34, and both ends of the adjusting spring 36 abut against the second guiding blocks 33 and the guiding column fixing block 35 respectively.

[0051] The elastic force of the adjusting spring 36 can drive the two opposite second guiding blocks 33 to approach each other, thereby driving the wedge-shaped limiting blocks 32 to approach each other.

[0052] After the material is inserted into the space between the tails of the two wedge-shaped limiting blocks 32, the top edge of the material abuts against the inclined surfaces of the wedge-shaped limiting blocks 32. Since the distance between the tails and the heads of the wedge-shaped limiting blocks 32 shortens, the material pushes the wedge-shaped limiting blocks 32 to both sides, thereby compressing the adjusting spring 36, and the elastic force of the adjusting spring 36 keeps the wedge-shaped limiting blocks 32 in contact with the material.

[0053] Since the inner side of the wedge-shaped stopper 32 is an inclined surface, the pressure of the wedge-shaped stopper 32 on the material can be decomposed into a horizontal thrust and a vertical downward pressure, the former ensuring that the material is located in the middle of the bottom mold 22, and the latter ensuring that the material fits the top surface of the bottom mold 22. Thus, it can adapt to materials of different thicknesses and sizes.

[0054] The positioning assembly 3 also includes a first limiting plate 31 , which is fixedly mounted on the top surface of the bottom mold 22 close to the frame 12 by screws, and the first limiting plate 31 is perpendicular to the head of the wedge-shaped limiting block 32 .

[0055] The first limiting plate 31 is used to limit the insertion depth of the material.

[0056] When using the device, the operator of this embodiment inserts the material from the space between the tails of the two wedge-shaped limiting blocks 32 until the front side of the material abuts against the first limiting plate 31 .

[0057] The top edge of the material abuts against the inclined surface of the wedge-shaped stopper 32. As the distance from the tail to the head of the wedge-shaped stopper 32 is shortened, the material pushes the wedge-shaped stopper 32 to both sides, thereby compressing the adjustment spring 36, and the elastic force of the adjustment spring 36 keeps the wedge-shaped stopper 32 in contact with the material.

[0058] Since the inner side of the wedge-shaped stopper 32 is an inclined surface, the pressure of the wedge-shaped stopper 32 on the material can be decomposed into a horizontal thrust and a vertical downward pressure, the former ensuring that the material is located in the middle of the bottom mold 22, and the latter ensuring that the material fits the top surface of the bottom mold 22. Thus, it can adapt to materials of different thicknesses and sizes.

[0059] By controlling the extension of the piston rod of the hydraulic cylinder 13, the top die 21 can be driven down, the top die 21 contacts the material and continues to apply pressure, and the top die 21 cooperates with the forming hole 23 to apply shear force to the material, thereby punching the material.

[0060] The waste generated by punching is discharged from the forming hole 23, falls to the slag discharge port 16, and then discharged from the slag discharge port 16.

[0061] After the punching is completed, the piston rod of the hydraulic cylinder 13 is controlled to shorten, driving the top die 21 to rise, so that the top die 21 is separated from the material, and then the material is drawn out from between the two wedge-shaped limit blocks 32 and replaced with new material.

[0062] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
