Background

The stamping process is a process commonly used in the machine manufacturing industry, which drives a stamping die mainly by a stamping apparatus to stamp a workpiece. The stamping part is separated from the die through a demoulding structure arranged in the die after being stamped and formed. However, the cavity of a portion of the die is deeper and the stamping is still within the cavity even though the stamping is disengaged from the die. At this time, the stamping part needs to be manually taken out, and the traditional mode is to use the clamping jaw to clamp out, but if the separation amplitude of the stamping part and the die is smaller, the gap between the edge of the stamping part and the cavity wall of the die is smaller, and the clamping jaw is difficult to extend into the rear of the stamping part to clamp the stamping part, so that the stamping part needs to be manually taken out at this time, and the stamping part is very inconvenient and dangerous.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

A safe pick-up device for stamping parts as shown in fig. 1-3 comprises a handle 100 for easy gripping and an elongated support bar 200 having one end fixedly connected to the handle. An oblong guide slot 110 is provided in the handle, in which a trigger 900 is mounted. It should be noted that the trigger is also oblong and shorter than the guide slot so as to slide in the guide slot. Meanwhile, an air duct 400 is fixedly installed on the support bar, the air duct is made of hard material, a suction cup 600 is installed at one end of the air duct far away from the handle, which is communicated with the air duct, and a flexible and elastic hose 200 is connected to the other end of the air duct 400, and one end of the hose is connected to a rear negative pressure device (not shown) after passing through the guide groove 110. In addition, an air hole 910 is formed on the portion of the hose connected to the wrench 900, and when a finger of a worker extends into the wrench and pulls the wrench, the finger covers the air hole to prevent external air from entering the pipeline through the air hole 210.

In addition, as shown in FIG. 1, a jaw assembly 500 capable of being flipped over after being pulled is also resiliently hinged to the end of the support bar remote from the handle 100. Specifically, the jaw assembly is connected to one end of a pull string 800, and the other end of the pull string is connected to the trigger 900. When a worker pulls the pulling buckle through fingers, the pulling buckle pulls the traction rope to enable the clamping jaw assembly to overturn, and the overturned clamping jaw assembly clamps the stamping part between the sucker and the clamping jaw assembly.

It should be noted that, as shown in fig. 3, the clamping jaw assembly 500 specifically includes a U-shaped roll-over stand 510 with a U-shaped structure, and two arms of the U-shaped roll-over stand are respectively connected with two rotating shafts 560 symmetrically disposed at ends of the support rod, so that the U-shaped roll-over stand has a capability of rotating relative to the support rod. Meanwhile, a torsion spring 550 is sleeved on the rotating shaft, one end of the torsion spring is connected with the supporting rod, and the other end of the torsion spring is connected with two arms of the U-shaped roll-over stand, so that the U-shaped roll-over stand can reset after being turned over. In addition, two arms of the U-shaped roll-over stand are respectively connected with a crank 530 in an extending way, the crank is C-shaped, the free end of the crank does not exceed the sucker when the U-shaped roll-over stand does not receive traction, and when the U-shaped roll-over stand rotates, the free end of the crank 530 abuts against the other surface of the stamping part sucked by the sucker so as to form a clamping state clamped on two sides with the sucker. Specifically, one end of the traction rope 800 is connected with the bottom of the U-shaped roll-over stand, the other end is connected with the spanner 900, and the spanner is pulled to move in the guide groove to realize the roll-over of the U-shaped roll-over stand.

It should be noted that, as a further improvement of the above embodiment, in order to increase the friction force between the crank 530 and the stamping when clamping the stamping, a rubber head 540 is sleeved on the free end of the crank.

In addition, in order to better adapt to stamping parts with various thicknesses, when the crank clamps the stamping parts, two contact points of the crank and the stamping parts and the contact points of the sucking discs and the stamping parts are positioned on the same horizontal line, and a telescopic rod 520 is further arranged between the crank 530 and two arms of the U-shaped roll-over stand 510.

It should be noted that, in the above embodiment, the support rod 300 has a C-shaped structure, which is advantageous in that the suction cup and the clamping jaw assembly on the support rod can be more conveniently inserted into the cavity of the mold.

Finally, in order to ensure that the traction rope 800 can be attached to the supporting rod, so as to prevent entanglement between the traction rope and the die, a plurality of wire buckles 700 are uniformly distributed on the supporting rod 300, and the traction rope 800 passes through the wire buckles.

Working principle: when the clearance between the demolding rear edge of the stamping part in the mold and the mold is small and the clamping jaw is inconvenient to extend, a worker holds the handle 100 to enable the sucker to press the surface of the stamping part, then fingers extend into the spanner and cover the air holes 210, at the moment, the sucker generates negative pressure due to the action of the negative pressure device, and the sucker is firmly adsorbed on the surface of the stamping part. The staff then pulls the stamping part up through the handle so that the gap between the edge of the stamping part and the die is increased. When the above steps are completed, the worker pulls the trigger 900 to pull the clamping jaw assembly, the clamping jaw assembly 500 is turned over, and the free end of the crank is pressed against the other surface of the stamping part, which is not adsorbed with the sucker 600. At this moment, this scheme forms to adsorb to the stamping workpiece, presss from both sides and gets two actions, and the stamping workpiece can be taken out from the mould by stable. When the stamping part is taken out, the staff releases the spanner button, the crank resets under the action of the torsion spring, and simultaneously, because the finger releases the air hole, the negative pressure on the sucker disappears, the stamping part can fall into the access frame of the stamping part immediately, and the safe taking of the stamping part is finished.
