Plate-spring universal powerful peening machine

Abstract

The invention relates to the field of metal workpiece surface treatment, in particular to a plate-spring universal powerful peening machine. The plate-spring universal powerful peening machine comprises a peening room, a collision type spray nozzle, a stress jig, a pill collecting device and a dust-removing mechanism. According to the plate-spring universal powerful peening machine, an upper rail and a lower rail are arranged on the two sides of a machine body of the complete machine, small walking wheels at the two ends of a chain walk between the upper rail and the lower rail for changing the soft property of the chain, the two sides of the chain are additionally provided with stress wall-plate fixing workpieces, a chain scraper board is matched with a hoister to conduct pill collecting, stive, scrap iron pills and sundries are separated by using a separator, and collision pill spraying is conducted by the collision type spray nozzle. The plate-spring universal powerful peening machine has the advantages that the structure is simple and practical, the cost is low, the pill spraying intensity is high, the flow is large, the coverage rate is high, energy is saved, blocking is avoided in the pill conveying, the workpieces are convenient to clamp, dust removing is timely, and the scrap pills can be separated.

Description

technical field [0001] The invention relates to the field of surface treatment of metal workpieces, in particular to a general-purpose powerful shot blasting machine for leaf springs. Background technique [0002] The shot blasting machine uses high-speed projectiles to directly hit the surface of the workpiece, thereby causing strong plastic deformation on the surface of the workpiece. After shot peening, the surface of the workpiece is cleaned, the adhesion of the coating layer and the anti-corrosion ability are improved, and the fatigue stress is eliminated to increase the surface hardness of the metal parts. Extend the service life; the commonly used shot blasting machine models are mainly pneumatic and centrifugal, and the pneumatic type is divided into suction type, gravity type and direct pressure type, all of which are shot blasting machines driven by compressed air to obtain high-speed motion.

[0002] The shot blasting machine uses high-speed projectiles to directly hit the surface of the workpiece, thereby causing strong plastic deformation on the surface of the workpiece. After shot peening, the surface of the workpiece is cleaned, the adhesion of the coating layer and the anti-corrosion ability are improved, and the fatigue stress is eliminated to increase the surface hardness of the metal parts. Extend the service life; the commonly used shot blasting machine models are mainly pneumatic and centrifugal, and the pneumatic type is divided into suction type, gravity type and direct pressure type, all of which are shot blasting machines driven by compressed air to obtain high-speed motion. Since the shot blasting room needs to install multiple nozzles, the required air compression is large, the flow rate is small, the device is complicated, the cost is high, and the shot peening intensity is poor; When the machine is in centrifugal operation, the wind pressure is high, the dust is scattered and flying, and the dust pollution is serious, and the centrifugal movement is frictional, which consumes projectiles and leaf dragons at the same time, and the nozzle is worn out, which has disadvantages such as high manufacturing cost, small flow rate, and poor flexibility.

[0003] The above-mentioned shot blasting machines all need a projectile recovery mechanism, a material conveying mechanism, and a dust removal mechanism, but the projectile recovery mechanism on the market is generally lifted by an auger, and there is a phenomenon that the auger is forced to send the shot to cause blockage; the conveying mechanism is generally a large turntable trolley The clamping force of the trolley-type fixture is from the middle to the top, and the force is concentrated on one point. It is very repulsive to clamp the straight leaf spring, and the trolley-type leaf spring runs out of joint, and there are many empty cars, resulting in waste. The stress mechanism is huge and the device is complicated. , the maintenance cost is high; the dust removal mechanism, the products on the market generally set up a pipe to suck the dust at the feeding place of the hoist. When the dust is sucked away, a lot of steel shots are also sucked away, resulting in waste, and the unqualified ones cannot be separated in time. steel shot
