Among the many types of shot blasting equipment, hook-type shot blasting machines, with their unique flexibility and adaptability, demonstrate irreplaceable advantages when handling complex and large workpieces. The Q37 series hook-type shot blasting machine, developed by Qingdao Puhua Heavy Industry Machinery Co., Ltd. based on twenty years of industry experience, is a mature solution in this field.
This equipment adopts a single or double hook design, allowing the workpiece to enter the shot blasting chamber in a suspended state. During the cleaning process, the hook drives the workpiece to rotate and revolve, ensuring that all surfaces, grooves, and cavities of the workpiece are fully exposed to the impact of the high-speed shot stream, achieving a thorough, three-dimensional cleaning without blind spots.
The equipment adopts a ground-mounted installation mode, eliminating the need for complex underground foundation structures. This design not only shortens the installation cycle and reduces civil engineering costs but also greatly facilitates subsequent equipment maintenance and repair, making it particularly suitable for upgrading existing workshop production lines.
The equipment excels in handling irregularly shaped and cavity parts. With lifting capacities ranging from 1,000 kg to 10,000 kg, it is available in various specifications to meet the cleaning needs of various complex structural workpieces, such as automotive engine blocks, engineering machinery supports, and large casting molds.
Multiple high-efficiency shot blasters are scientifically arranged according to common workpiece shapes, and with adjustable blasting parameters, ensure that each batch of workpieces achieves a uniform surface quality. The surface cleanliness of the treated workpiece consistently meets the national standard of Sa2.5.
The equipment is equipped with a programmable control system that can store processing parameters for different workpieces. Operators only need to call the corresponding program, and the equipment can automatically control the entire process, including loading and unloading, shot blasting time, and shot flow rate, effectively reducing reliance on operator experience.
The shot circulation system is equipped with a high-efficiency magnetic separator and vibrating screen, achieving a clean shot recycling rate of over 95%. Combined with a low-energy-consumption fan and an optimized shot blasting unit, the overall energy consumption per ton of workpiece is at an advanced level in the industry.
The Q37 hook shot blasting machine plays a key role in multiple industries:
Foundry Industry: Used for cleaning complex castings such as engine housings, gearboxes, pumps, and valves.
Construction Machinery: Suitable for rust removal and strengthening of components such as excavator bucket teeth, hydraulic valve blocks, and chassis.
Steel Structures: Used to process welded trusses, beams, and columns, removing weld slag and stress.
Automotive Manufacturing Industry: Used for cleaning molds, large fixtures, and prototype parts.
Qingdao Puhua Heavy Industry has invested heavily in equipment durability. The shot blasting chamber features a multi-layered protective design, with the innermost layer being a replaceable high-chromium alloy wear-resistant plate, significantly extending the service life of the main structure. All bearings, seals, and other key components are sourced from well-known domestic and international brands, ensuring long-term stable operation.
The company has established a service system covering the entire lifecycle of the equipment. From initial site planning and basic guidance to operational training during installation and commissioning, and subsequent regular inspections and rapid spare parts supply, we ensure worry-free use for our customers.
Choosing the right shot blasting equipment is crucial for improving product quality and extending workpiece life. The Q37 hook shot blasting machine, with its excellent handling capabilities for complex workpieces, stable and reliable cleaning results, and convenient installation and maintenance, has become a standard configuration for many manufacturing companies.
As the manufacturing industry moves towards refinement and high quality, the importance of surface treatment is increasingly prominent. Qingdao Puhua Heavy Industry will continue to optimize product performance, providing the industry with more efficient and reliable hook shot blasting solutions.
