Description

Technical Field

[0001] The utility model belongs to the technical field of piece-taking devices, in particular to a surface-damage-free piece-taking device for processing metal forgings. Background Art

[0002] Metal forgings are workpieces or blanks obtained through a forging process, a process that involves applying pressure to a metal blank to cause it to plastically deform, resulting in a forging with specific mechanical properties, shape, and dimensions. Forging is a machining method that is one of the two main components of forging (forging and stamping). Through forging, defects such as as-cast porosity produced during the metal smelting process can be eliminated, the microstructure can be optimized, and because the metal flow lines are preserved, the mechanical properties of forgings are generally superior to those of castings of the same material. This machining method is widely used to manufacture critical parts subjected to high loads and harsh working conditions. Except for parts with simpler shapes, forgings are used in most cases. The metal forging process requires the use of machinery to remove the parts.

[0003] For example, the Chinese utility model patent with publication number CN219151465U discloses a surface-damage-free removal device for metal forging processing, comprising a base, a mounting frame fixedly mounted on the upper end face of the base, a load plate fixedly connected to the mounting frame, a U-shaped frame fixedly mounted on the load plate, a cylinder fixedly mounted on both sides of the top wall of the U-shaped frame, a lifting frame fixedly mounted on the piston end of the cylinder, a mounting slot provided in the lifting frame, and a clamping device provided in the mounting slot. In the present utility model, a plurality of limit plates provided on the conveyor belt can fix the metal forging between two adjacent limit plates, preventing the clamping plates from touching the surrounding metal forgings during transportation and causing damage to the product surface. The removal action is completed cyclically by the provided cylinder, electric slide rail and clamping plate. The clamp for metal forging processing has a simple structure, is easy to operate and has a low cost.

[0004] However, the above-mentioned new method still has certain defects. On the one hand, the rigid support design used for removing parts can easily damage the surface of metal forgings. On the other hand, the clamping range does not have a wide range of adjustment capabilities and cannot meet the clamping and removal operations of metal forgings of different sizes. Utility Model Content

[0005] In order to solve the technical problems that the rigid clamping design used in the reference documents in the above background art is easy to damage the surface of the metal forging, and on the other hand, its clamping stroke is short and cannot meet the requirements of clamping and removing metal forgings of different sizes, the present utility model provides the following technical solutions:

[0006] The utility model relates to a surface non-destructive pick-up device for metal forging processing, comprising a mechanical arm, an adjustment seat and an electric clamp, wherein the adjustment seat is mounted on the pick-up end of the mechanical arm, a driving screw is rotatably mounted in the adjustment seat, two guide slides are fixedly mounted in the adjustment seat, a screw mounting seat is slidably mounted on the two guide slides, the electric clamp is fixedly mounted on the bottom of the adjustment seat, a plurality of clamping claws are arranged in an equidistant circular array on the electric clamp, a first slide rail is integrally formed on the end of the clamping claw away from the electric clamp, and further comprising:

[0007] A clamping assembly is installed on the clamping jaw for clamping forgings, and the clamping assembly includes a second slide rail, a first slider and a negative pressure plate. The first slider is slidably installed on the first slide rail, and the second slider is fixedly installed on the back of the negative pressure plate. The second slider is slidably installed in the second slide rail, and a plurality of clamping heads are movably inserted on the negative pressure plate.

[0008] As a preferred technical solution of the present invention, the screw mounting seat is engaged with the driving screw, and a motor for driving the driving screw to rotate is fixedly mounted on the side end of the adjustment seat.

[0009] As a preferred technical solution of the present invention, a plurality of first positioning holes are provided on the first slide rail, and a first positioning bolt threadedly adapted to the first positioning holes is inserted into the first sliding block.

[0010] As an optimal technical solution of the present invention, a plug connector is fixedly welded on the top of the second slide rail, and a plug socket that is plugged into and adapted for the plug connector is integrally formed at the bottom of the first slider. The plug connector and the plug socket are provided with a second positioning hole that passes through the front and back, and a second positioning bolt that is threaded and adapted is provided in the second positioning hole.

[0011] As a preferred technical solution of the present invention, a plurality of third positioning holes are provided on the second slide rail, and two third positioning bolts threadedly matched with the third positioning holes are inserted into the second slide block.

[0012] As a preferred technical solution of the present invention, a spring holder is provided at one end of the clamping head located inside the negative pressure plate, and a return spring is fixedly installed between the spring holder and the negative pressure plate.

[0013] As a preferred technical solution of the present invention, the clamping head is located in a section inside the negative pressure plate and is provided with a plurality of negative pressure air holes.

[0014] As a preferred technical solution of the present invention, the clamping head is made of hard rubber and an air suction hole is provided cocentrically with one end of the clamping head away from the negative pressure plate.

[0015] The beneficial effects achieved by the utility model are:

[0016] When the negative pressure plate clamps the metal forging, the clamping head retracts to fit the metal forgings of different shapes, making the clamping more stable. The negative pressure plate is connected to an external negative pressure air pump. The negative pressure air pump draws air through the negative pressure air holes on the clamping head and sucks the metal forging through the suction holes. The negative pressure adsorption clamping method will not damage the surface of the metal forging.

[0017] When a clamping assembly is set up, the three clamping assemblies face each other and the electric clamp drives the clamping claws to grab and release to achieve the purpose of clamping small-diameter metal forgings, and the motor drives the mounting base to move on the guide slide rod to adjust the horizontal position of the clamping assembly.

[0018] When two clamping assemblies are set in mirror image, and the threads on both sides of the driving screw have opposite directions and the same pitch, the direction of the clamping assembly is adjusted by the rotation of the plug connector and the socket. When the two negative pressure plates close to each other on the two clamping assemblies face each other, the motor drives the two screw mounting seats to move in opposite directions at the same speed on the guide slide, thereby achieving the purpose of clamping larger metal forgings.
