Description

Technical Field

[0001] The utility model relates to the field of stamping equipment, in particular to an adsorption type stamping die. Background Art

[0002] Stamping is a forming processing method that relies on a press and a die to apply external force to plates, strips, tubes and profiles to cause plastic deformation or separation, thereby obtaining stamped parts of the desired shape and size. Before stamping, the parts to be stamped need to be placed in the die. When placed manually, if the switch is touched by mistake, the worker's hand will be directly squeezed, causing a safety accident, so other methods of placing and taking materials are used.

[0003] For example, the adsorption plate of the prior art places the stamping parts on the stamping die by magnetic attraction or air attraction. However, when adsorbing, the position of the stamping parts moves, and the placement position after adsorption will also change, causing the placement position of the stamping parts to be offset, thereby affecting the quality of the product or even scrapping it. Utility Model Content

[0004] In order to overcome the disadvantage that the adsorption placement position is based on the position where the stamping parts are stacked, which is prone to placement deviation and causes workpiece quality problems, the utility model provides an adsorption stamping die with a fixed placement position.

[0005] A suction-type stamping die comprises a machine base, a bracket, a punch, an upper die, a lower die, an suction rotating frame, a adsorber, a mounting seat, a telescopic frame, an elastic member and a limit block. The bracket is fixedly connected to the top of the machine base, the punch is mounted on the bracket, the upper die is arranged at the bottom of the punch, the lower die is arranged on the top of the machine base, a rotatable suction rotating frame is arranged on the machine base, a telescopic adsorber is arranged at the outer end of the suction rotating frame, a mounting seat is arranged on the machine base and is located around the lower die, a telescopic frame is slidably connected to the mounting seat, a limit block is arranged in the direction of the telescopic frame toward the lower die, and an elastic member is arranged on the telescopic frame and is located between the mounting seat and the telescopic frame.

[0006] Further description, the adsorption rotating frame is provided with rocker arms which are perpendicular to each other, and a rotating motor is arranged at a right angle, and the rocker arms of the adsorption rotating frame can be extended and retracted.

[0007] It is further explained that the vertical cross-section of the limit block is approximately a right-angled trapezoid, with the oblique line pointing toward the lower mold in the middle.

[0008] Further description, it also includes a guide rod and a screw rod, the guide rod is slidably connected to the telescopic frame, the limit block is fixedly connected to the guide rod, the limit block is fixedly connected to the screw rod, and the screw rod is threadedly connected to the telescopic frame.

[0009] Further description, it also includes a wedge block and a push rod, the wedge block is fixedly connected to the two ends of the telescopic frame, and the push rod is fixedly connected to the periphery of the upper mold.

[0010] Further description, it also includes a scale, which is fixed on the telescopic frame.

[0011] The beneficial effects of the utility model are:

[0012] 1. The utility model fixes the workpiece to be stamped from all sides by means of limit blocks, so that when the workpiece to be stamped is placed, it can be ensured that the workpiece to be stamped is located in the middle of the die, thereby ensuring the quality of the workpiece after stamping. The wedge block and the push rod cooperate to make the limit block leave the workpiece to be stamped before stamping, which is suitable for stamping with different dies and improves applicability.

[0013] 2. The utility model adjusts the distance of the limit block by means of a screw rod, so that the same fixing effect can be achieved for parts to be stamped of different sizes, thereby not affecting the adsorption process. The displacement distance of the screw rod can also be accurately adjusted by means of a scale, thereby improving the accuracy of the adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0019] Embodiment: An adsorption stamping die, such as Figure 1-Figure 3As shown, it includes a machine base 1, a bracket 2, a punch 3, an upper mold 31, a lower mold 32, an adsorption rotating frame 4, an adsorbent 41, a mounting base 5, a telescopic frame 6, an elastic member 7 and a limit block 8. The bracket 2 is welded to the top of the machine base 1, the punch 3 is mounted on the bracket 2, the upper mold 31 is connected to the bottom of the punch 3 by bolts, the lower mold 32 is connected to the middle of the top of the machine base 1, and a rotatable adsorption rotating frame 4 is installed on the machine base 1. The adsorption rotating frame 4 is provided with rocker arms perpendicular to each other, and a rotating motor is provided at a right angle. , and the rocker arm of the adsorption rotating frame 4 can be retracted, and a retractable adsorber 41 is installed at the outer end of the rocker arm of the adsorption rotating frame 4, and four mounting seats 5 are arranged on the machine base 1, which are located around the lower mold 32, and the mounting seats 5 are slidably connected with a telescopic frame 6, and a limiting block 8 is arranged in the direction of the telescopic frame 6 toward the lower mold 32. The vertical cross-section of the limiting block 8 is approximately a right-angled trapezoid, and the oblique line faces the middle lower mold 32. The elastic member 7 is sleeved on the telescopic frame 6, one end of which is welded to the telescopic frame 6, and the other end is welded to the mounting seat 5.

[0020] The staff places the workpiece to be stamped on the machine base 1 or one side, then opens and adjusts the telescopic distance of the adsorption turret 4 during material discharge, so that the workpiece to be stamped can be adsorbed. Then the punch 3 and the adsorbent 41 are opened, and the adsorbent 41 puts down the suction cup, adsorbs the workpiece to be stamped and then retracts. The adsorption turret 4 is rotated 90 degrees counterclockwise to move the workpiece to be stamped to the top of the lower die 32, and then the workpiece to be stamped is pressed downward. At this time, the extrusion limit block 8 moves outward and pushes the telescopic frame 6 to move, thereby displacing the mounting seat 5, thereby compressing the elastic member 7. After being pressed to the bottom, the adsorption of the workpiece to be stamped is released, and the adsorption turret 4 is rotated 45 degrees clockwise. At this time, The limit blocks 8 on all sides and the connected elastic parts 7 can adjust the compression distance of the elastic parts 7 with each other, so that the parts to be stamped can be in the center position of the lower mold 32, and then the upper mold 31 is pressed down by the punch 3. After the stamping is completed, the upper mold 31 is reset upward, and the adsorption turntable 4 is rotated 45 degrees clockwise. While one adsorber 41 adsorbs the stamped workpiece, the other adsorber 41 completes the adsorption of the parts to be stamped. After rotating 90 degrees counterclockwise, while completing the material removal, the next piece of parts to be stamped is also discharged. This cycle is repeated to complete the processing of all parts to be stamped, and then all equipment is closed.

[0021] like Figure 2 and Figure 3 As shown, it also includes a guide rod 9 and a screw rod 10. The guide rod 9 is slidably connected to the telescopic frame 6. The limit block 8 is welded to the guide rod 9. The screw rod 10 is welded to the limit block 8. The screw rod 10 is threadedly connected to the telescopic frame 6.

[0022] like Figure 1 and Figure 2As shown, it also includes a wedge block 11 and a push rod 12. The wedge block 11 is welded to both ends of the telescopic frame 6, and the push rod 12 is welded around the upper mold 31.

[0023] like Figure 2 and Figure 3 As shown, a scale 13 is also included, and the scale 13 is fixed to the telescopic frame 6 by bolts.

[0024] When replacing the mold, some molds will squeeze the side of the lower mold 32, so that through the push rod 12 on the side of the upper mold 31, when moving downward, it can squeeze the wedge block 11, thereby driving the telescopic frame 6 to move outward. At this time, the part to be stamped is already located at the center of the lower mold 32, and the limit blocks 8 around it follow the telescopic frame 6 and leave the part to be stamped at the same time, so the part to be stamped will not be displaced, thereby meeting the mold requirements. For parts to be stamped of different sizes, the distance between the limit block 8 and the center of the lower mold 32 can also be adjusted by the screw 10 to achieve the same fixing effect, and the adsorption process of the adsorber 41 will not be affected by the extrusion force being too large. In addition, through the scale 13 on the telescopic frame 6, the distance of the limit block 8 can be accurately adjusted when the screw 10 is rotated according to the size change of the part to be stamped, thereby optimizing the fixing effect of the part to be stamped.

[0025] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
