Hook Shot Blasting Machine

The hook shot blasting cleaning machine is suitable for surface cleaning of small and medium-sized steel structural parts, profiles, castings, forgings and other workpieces. The equipment has the characteristics of high working efficiency, good automation, powerful protection functions, simple maintenance and repair, and convenient maintenance.

This machine has the functions of fixed-point feeding, unloading, and rotary shot blasting of workpieces. Through shot blasting cleaning, rust, scale, dirt, etc. on the surface of the part can be removed, so that the surface of the workpiece will show the metallic primary color. At the same time, it can reduce the stress in the workpiece, improve the corrosion resistance of the product and the fatigue resistance of the product, and extend its service life; optimize the surface process status of the metal material.

The use of shot blasting cleaning technology to achieve the purpose of rust removal and strengthening has also laid a good foundation for the subsequent inspection, flaw detection, coating and other processes.

※ Digested and absorbed shot blasting design technology of foreign companies, so that this machine has the characteristics of advanced design, reasonable structure, reliable operation and high production efficiency.

※ The projection schematic, chamber structure and general drawing are used to draw the interior of the chamber body with computer-aided design (CAD) to prepare special wear-resistant alloy protection, which can effectively improve the service life of the chamber body and make full use of the rebound force of the projectile to form secondary cleaning.

※ The shot blasting device adopts the Q034 shot blasting device with the advantages of fast shot blasting speed, high efficiency, large projection area, low noise, stable operation, uniform output cleaning, and convenient maintenance. It can significantly improve the cleaning efficiency of 25%, shorten the time, improve the production efficiency of the operator, and obtain satisfactory cleaning quality;

※ The pneumatic double doors ensure no splash of steel balls, reduce feeding space and reduce costs.

※ The labyrinth hook seals the passage to ensure that there is a small amount of projectile dust escapes.

※ The electric hoist conveys workpieces, which are stable in operation, easy to load and unload.

※ The screw conveying adopts advanced three-level sealing protection method, and the sealing effect is good.

※ Electrical components have the advantages of high reliability and easy maintenance. The main circuit is short-circuit, phase loss and overload protection for each motor by a small circuit breaker and thermal relay. It also has an emergency stop switch to facilitate emergency shutdown and prevent accidents from accelerating;

※ The dust collector uses a cyclone + bag dust collector, and the dust removal effect is more significant. The air suction ports of the shot blasting cleaning room suck out the indoor dust through the suction duct, sorted by the separator, and then filtered through the dust collector, and the dust particles with a density greater than the gas. The density less than the gas finally enters pulsed environmentally friendly dust removal for secondary dust removal, and finally discharges the exhaust gas, and the dust concentration in the discharged exhaust gas is less than 50 mg/m3; the dust removal fan outlet is equipped with a silencer device to reduce equipment noise and protect the occupational health of the staff.

※ The assembly structure of the whole machine has a beautiful and novel appearance and is easy to install and repair.

Hook shot blasting cleaning machines are specially designed for meeting users' specific process requirements. With the purpose of removing sand, dirt, rust, and oxide scale on the surface of complex workpieces, the surface of the workpiece is smooth and metallic. At the same time, it can improve the surface fracture resistance, reduce the internal stress of the workpiece, and clean and strengthen the surface of the workpiece, thereby providing good conditions for the subsequent inspection, flaw detection, coating and other processes.

1. When the preparation work is completed, start the dust collector, separator, hoist, and screw conveyor in order;

2. Open the door, hoist the workpiece on the homemade workpiece, use an electric hoist to lift the workpiece to the predefined height upper limit position, and transport it to the shot blasting room;

3. The door of the shot blasting room is closed, and the proximity switch automatically detects whether the door is completely closed; after the shot blasting device is opened for 8S (if the door is not completely closed, the shot blasting device will not start), the ballast supply valve is opened, the rotation device is operated, and the workpiece can be rotated. According to the cleaning situation, the cleaning time can be set at any time on the control cabinet (the cleaning time must be set before the shot blasting work is opened). While rotating, the workpiece is subject to the impact and scraping of the powerful projectile flow beam from two shot blasting devices on one side, 360 degrees fully inclusive;

4. After the cleaning work is completed, close the supply valve and delay the 30S (to the blasting pipe and the steel balls in the shot blasting device are completely thrown out), close the shot blasting device until the shot blasting device is completely stopped (the air blades of the shot blasting motor can be judged. It is strictly forbidden to open the door before the shot blasting device is completely stopped to prevent the bullets from flying out and injuring people). Open the door. The cleaned workpiece is driven by the electric hoist and is transported to the shot blasting room to unload and load the material; the other group of lifted workpieces is waiting to enter the shot blasting room for cleaning, and the cycle is carried out.

5. After the cleaning work is completed, close the hook rotation device, screw conveyor, hoist, separator, dust collector, and close the door in turn. Press the pulse backblowing button on the electrical control cabinet panel, pulse backblowing the dust collector for about 15 minutes and then cut off the main power supply.
