    Máquina de granallado de gancho giratorio 1200×1600 para limpieza de piezas de forja

Máquina de chorreado de arena tipo doble gancho colgante

La máquina de granallado de gancho es el modelo estándar para procesos de granallado. Cuenta con un cilindro de trabajo de diámetro entre 900 y 1300 mm y altura comprendida entre 1300 y 3500 mm. Esta máquina polivalente está equipada con 2‑7 turbinas de granallado y soporta una carga máxima de 10 000 kg. Ofrece alta eficiencia productiva y gran flexibilidad, por lo que resulta una opción ideal para aplicaciones de limpieza y refuerzo superficial. Su manejo es sencillo: basta con cargar la pieza de trabajo, pulsar el botón de arranque y, en poco tiempo (normalmente 5‑7 minutos), finaliza todo el proceso de limpieza eliminando todo el polvo y los restos de granalla.

La máquina de granallado de gancho es adecuada para el tratamiento superficial de diversas piezas medianas y grandes de fundición, forja, soldadura y piezas tratadas térmicamente, incluso piezas frágiles y de forma irregular. Es especialmente indicada para la limpieza y el refuerzo superficial de piezas delgadas y de pared fina. Al realizar un granallado potente sobre la superficie del acero, elimina eficazmente manchas de óxido, escoria de soldadura e incrustaciones de óxido, obteniendo una superficie metálica lisa y de brillo uniforme. Además, ayuda a aliviar las tensiones internas, mejora la calidad del recubrimiento superficial y aumenta la resistencia a la corrosión del acero.

Aplicación

Este tipo de máquina de limpieza es apta para la limpieza superficial o el tratamiento de refuerzo de piezas de fundición y forja de tamaño pequeño y mediano en sectores como fundición, construcción, industria química, material eléctrico, máquinas‑herramienta y otros. Es especialmente adecuada para la limpieza superficial y el granallado de piezas de fundición, forjados y elementos estructurales de acero de múltiples variedades y lotes reducidos, con el fin de eliminar pequeñas cantidades de arena, núcleos de arena e incrustaciones de óxido de la superficie de la pieza de trabajo. También sirve para la limpieza y el refuerzo superficial de piezas tratadas térmicamente. Resulta idónea para la limpieza de piezas alargadas y de pared fina que no soportan impactos.

Principio de funcionamiento

Durante el funcionamiento del equipo, una vez finalizadas las tareas de preparación (sistema de desempolvado, elevador, transportador de tornillo sin fin, etc.), la máquina entra en operación normal. En primer lugar, el gancho desciende para elevar la pieza de trabajo, asciende hasta una posición determinada y entra en la cámara de granallado por la vía. Al llegar a la posición predefinida, se detiene y empieza a girar. A continuación, se cierra la compuerta de la cámara de granallado, se activan los dispositivos de granallado y se abre la compuerta de proyección para iniciar el granallado sobre la pieza. Se repite este ciclo hasta finalizar la tarea y se realiza el apagado secuencial del equipo.

Q: Is the forklift industry ushering in a "super cycle"?

A: The industry data just released is too explosive! In October 2025, forklift sales 114,300 units, domestic and foreign sales soared by double digits (domestic sales + 16.2%, export sales + 15.4%), and the cumulative sales from January to October exceeded 1.22 million units, surging 14.2% year-on-year! On the one hand, JD.com spent 100 billion to purchase 3 million logistics robots, and on the other hand, hydrogen forklifts single order surged 108 units. The forklift industry is experiencing a "green + intelligent" dual revolution. These changes!

Q: How does a smart forklift work?

A: Have you seen how a smart forklift works? Recently, CCTV news came to Hefei and walked into the intelligent workshop of Anhui Forklift Group. Let's follow the camera. This 67-year-old enterprise is on a path of transforming and upgrading traditional industries and developing new quality productivity. Now I have come to the debugging and testing area of the mobile robot. More than a dozen cars behind me are conducting sensor calibration and basic function testing here. I am now standing on its forward path. In the eyes of the robot, I am an obstacle, and it will automatically stop.

Q: Smart Forklift "Create a new model of safety supervision?

A: According to the staff of Xinhe Food, the system integrates a number of intelligent management functions, and builds a comprehensive protection system through comprehensive digital control of personnel, vehicles and behaviors. The personnel management module realizes the digitization of the driver's account and real-time early warning; the vehicle positioning function ensures the safe operation of the forklift in the electronic fence; the operation early warning actively reminds to fasten the seat belt; the identification mechanism strictly restricts only the filing personnel to operate the vehicle, fundamentally eliminating unlicensed driving. At the same time, the system also has data analytics capabilities to provide reliable data support for vehicle scheduling and performance mangement.
