Small steel shot feeding circulator and numerical control metal surface treating machine using the same

Abstract

The invention relates to a small steel shot feeding circulator, which comprises a feeding motor, a dual-layer sprocket, double chains and a plurality of feeding funnels, and is characterized in that a box body is arranged, an impeller head installation space is arranged in the box body, and a steel shot window and a seal guard are arranged on the front wall of the box body; and the feeding motor, the dual-layer sprocket, the double chains and the feeding funnels are arranged in the box body around the impeller head, a feed hopper and a return hopper are arranged, and steel shots are delivered to the feed hopper through the feeding funnels. The invention additionally relates to a numerical control metal surface treating machine, which comprises a traveling base, an operating room, a control cabinet, a hydraulic station, a dust catcher, the impeller head, a movable supporting arm and a steel shot feeding circulating system, and is characterized in that the steel shot feeding circulating system is the small steel shot feeding circulator, the two-dimensional movable supporting arm is adopted, and a plus or minus 180-degree rotating platform is arranged on the traveling base. The invention has the advantages that the volume is small and the weight is light, the structure is simplified, the moving range of the impeller head is widened, the operation flexibility of the entire machine is improved, the safety stability is improved, the cost is reduced and the application scope is widened.

Description

technical field [0001] The invention relates to equipment for metal surface treatment using a shot blaster, in particular to a small steel shot feeding circulator and a numerically controlled metal surface treatment machine using the device Background technique [0002] In the equipment manufacturing industry, some large-scale cylindrical structures such as: wind power generation towers, transport tankers and large oil storage tanks in the petrochemical industry require surface treatment. Generally, the surface of the workpiece is impacted by shot blasting to remove rust and other attachments and form requirements. surface roughness and then surface coating. For a long time, with the development of surface treatment technology for large cylinders, shot peening technology has entered the stage of open treatment with spray guns, shot blasting rooms and manual operation from the traditional high energy consumption, high noise, and serious environmental pollution. Through the t...

Problems solved by technology

But this equipment has the following defects: (1) The three-dimensional operation of the shot blasting head needs to be completed through the control of three sets of mechanisms, that is: the hydraulic cylinder lifting mechanism directly pushes to complete the up and down operation, and the machine driven by the motor to push and pull the lead screw moves. The table completes the forward and backward movement facing the barrel, and the left and right movement along the axis of the barrel along with the entire walkable machine base. The structure and control are complex, especially the forward and backward movement is driven by the screw rod with small stroke, high friction, slow speed, and flexibility is not easy to guarantee.

(2) The steel shot circulation system consists of a feeding box that runs through the cylinder of the feeding cylinder, a steel shot lifting mechanism, a return box and a telescopic tube. The steel shot process is too long, the structure space is large, the system structure is complicated, the production cost is high, and the overall The control and movement of the machine is not flexible, and the safety and stability are poor. This structure also limits the expansion of the range of the shot blasting machine. At present, the up and down movement range of the shot blasting machine is only about 1 meter, which is only suitable for the surface treatment of large cylinders. For It is not applicable to the surface treatment of equipment manufacturing, ships, large petrochemical containers, large box bridges and other larger bodies including large plane structures

(3) The existing equipment is too large, the center of gravity is unstable, it cannot be rotated, and it is difficult to change the working position, so it is not suitable for production line operations, and can only handle workpieces on one side

(4) It is heavy and cannot be transported as a whole machine, especially inconvenient to assemble and disassemble, which increases the shipping cost
