Abstract
Description
Technical Field
[0001] This utility model relates to the field of weighing device technology, specifically a rapid material removal and weighing device for formed green blanks. Background Technology
[0002] Powder metallurgy is mainly applicable to the production and research of spare parts in the automotive, equipment manufacturing, metal industry, aerospace, military industry, instrumentation, hardware tools, and electronic appliances sectors. Products include bearings, gears, cemented carbide cutting tools, molds, friction products, etc. In military enterprises, heavy weaponry such as armor-piercing projectiles and torpedoes, as well as brake components for aircraft and tanks, all require powder metallurgy technology for production. Powder metallurgy automotive parts have become the largest market in China's powder metallurgy industry in recent years, accounting for approximately 50% of automotive parts. Traditional powder pressing and forming methods mostly involve filling powder with a feeding shoe while simultaneously pushing out the previous product. After being pushed out, the product flows to the receiving point via a chute or conveyor belt. The advantage of this method is that the output cycle perfectly matches the pressing cycle. The disadvantages are that product flipping cannot be achieved, real-time weight monitoring is not possible for products with high precision requirements, and due to the low strength of the formed green blank, it is easily broken and deformed under stress. This method has high requirements for the shape of the produced products and a narrow scope of application. To meet the material handling needs of various product types, automated material handling methods have been developed, including multi-cylinder / rotary cylinder combination material handling solutions and industrial robotic arm material handling solutions. Multi-cylinder combination material handling has a simple structure and low cost, but poor stability, with a maximum cycle time of 15-20 pieces / minute when combined with weighing. Industrial robotic arms offer high reliability, with a maximum cycle time of approximately 25-30 pieces / minute when combined with weighing, but are more expensive and less economical. In recent years, with the development of rapid prototyping machines, the pressing speed of forming presses has significantly improved. Multi-cylinder combination solutions, due to limitations in the response speed of their own cylinders, are gradually becoming unable to match the press speed. Utility Model Content

[0021] Please see Figure 2-4 The mounting mechanism 5 includes a slider 51. A connecting block 52 is fixedly connected to the side of the slider 51 near the Z-axis linear module 1. The connecting block 52 is slidably connected to the mounting base 4. A locking block 53 is fixedly connected to the side of the connecting block 52 near the Z-axis linear module 1. A locking groove 54 is provided inside the Z-axis linear module 1. The locking block 53 contacts the mounting base 4 and is slidably connected to the locking groove 54. Through the design of the locking block 53, the mounting base 4 can be limited.
[0022] Please see Figure 2-4The mounting base 4 has a threaded rod 55 rotatably connected inside. The outer side of the threaded rod 55 is provided with positive and negative threads. The threaded rod 55 is threadedly connected to the slider 51. The design of the threaded rod 55 can drive the two sliders 51 to move simultaneously. A retaining ring 56 is fixedly connected to the outer side of the threaded rod 55. The retaining ring 56 contacts the inner wall of the mounting base 4. The design of the retaining ring 56 can limit the movement of the threaded rod 55. A knob 57 is fixedly connected to the upper end of the threaded rod 55.

[0023] The specific implementation process of this utility model is as follows: In use, by installing the mounting base 4 with the Z-axis linear module 1, the mounting base 4 drives the locking block 53 to slide into the locking groove 54 on the Z-axis linear module 1. Then, rotate the knob 57 to drive the threaded rod 55 to rotate, so that the threaded rod 55 and the slider 51 have a threaded movement, thereby causing the slider 51 to drive the connecting block 52 to move, and the connecting block 52 to drive the locking block 53 to move, so that the locking block 53 is engaged with the Z-axis linear module 1, and the mounting base 4 and the weighing module 42 and other components can be installed on the Z-axis linear module 1.
[0024] - The X-axis linear module 2 moves forward, and the gripper 32 moves to the "waiting position". Waiting
[0025] - When the product is demolded and the upper cylinder is raised to the set position, the X-axis linear module 2 advances. The gripper 32 moves to the "grip position".
[0026] - Linear cylinder 3 extends, Z-axis linear module 1 descends, and gripper 32 can clamp the product. Clamping.
[0027] Linear cylinder 3 retracts, X-axis linear module 2 moves backward, and Z-axis linear module 1 rises. Gripper 32 moves to the "safe position".
[0028] - Gripper 32 rotates 180° (if needed), X-axis linear module 2 continues to retract, and Z-axis linear module 1 descends. Gripper 32 moves to the "discharge position".
[0029] - Gripper 32 releases. The material is then placed on the weighing module 42.
[0030] - The Z-axis linear module 1 is raised, the X-axis linear module 2 moves forward, and the gripper 32 moves to the "waiting position".
[0031] wait
[0032] When the gripper 32 releases the material, it places the product on the weighing module 42, which weighs the product. If the weight is within the set range, the universal arm blowing head 44 blows the product onto the conveyor belt. If the weight exceeds the set range, the throwing flap 43 opens, and the universal arm blowing head 44 blows the product into the NG material channel.
[0033] In actual operation, the "waiting position," "grip position," "safety position," and "discharge position" are determined by two sets of coordinates (X, Z). Different grippers 32 are set by the operator on the control panel during machine setup. Press-related parameters, such as upper punch diameter, height, and die position, can be input into the controller. To ensure safety, when the operator sets the above coordinate positions, the controller automatically calculates whether there is any interference with the press-related positions. If interference occurs, an alarm is triggered, and the setting cannot be changed.
