设备介绍：

履带式抛丸清理机主要用户是机床厂、汽车厂、弹簧厂、热处理车间、铸造车间和冲压车间。履带式抛丸机利用高速 回转的叶轮，将弹丸抛向滚筒内连续翻转的工件上，达到清理的目的。它适合对各行业中的小小型铸件、锻件、冲压件等 进行抛丸除锈、去除氧化皮和表面强化，特别适用于不怕碰撞的零件的表面清理及强化。铸件经过拋丸清理，加工面便于 下道机械加工工序，不但可节省加工时间，而且可保护机床和刀具不受损坏；非加工面涂漆后，经久不脱，提高产品使用 寿命和外观质量。

The main users of crawler shot blasting machine are machine tool factory, automobile factory, spring factory, heat treatment workshop, casting workshop and stamping workshop. The crawler-type shot blasting machine uses the impeller rotating at high speed to throw the shot onto the continuously turned workpiece in the drum to achieve the purpose of cleaning. It is suitable for blasting rust removal, scale removal and surface strengthening of small castings, forgings and stamping parts in various industries, especially for surface cleaning and strengthening of parts that are not afraid of collision. After the casting is shot-blasted, the machined surface is convenient for the next machining process, which not only saves the machining time, but also protects the machine tool and cutter from being damaged; After the non-processed surface is painted, it will not take off for a long time, thus improving the service life and appearance quality of the product.

工作原理

在清理室中加入规定数量的工件，机器启动后，滚筒开始旋转，被清理的工件由橡胶履带带动在滚筒内作连续均匀的 翻转，同时拋丸器高效抛出弹丸形成扇形弹束，均匀的打在工件表面上，从而达到清理和强化的目的。抛出的弹丸及砂 粒，经橡胶履带均匀排布的小孔流入清理室底部的钢板筛上，钢板筛将较大颗粒筛出钢丸及细砂落至筛下的螺旋输送器， 被送入提升机内，由提升机提至丸砂分离器中进行分离，粉尘由风机吸送至滤筒式除尘器内经滤筒过滤，清洁空气排放大 气，滤筒上的灰尘有脉冲反吹落入除尘器下部集尘箱内，定期除尘。旧砂经流砂管流入废砂桶内(用户自备)。由分离器 中钢板筛筛下的较大颗粒与未能分离完成的丸砂混合物，经流丸管流入清理室。重新参加分离，分离后干净的弹丸，经流 丸管再次流入抛丸器内重新开始抛丸工作。

A specified number of workpieces are added into the cleaning room. After the machine is started, the drum starts to rotate, and the cleaned workpieces are driven by the rubber crawler to continuously and uniformly turn over in the drum. At the same time, the shot blasting device efficiently throws out the shot to form a fan-shaped bullet beam, which evenly hits the surface of the workpiece, thus achieving the purpose of cleaning and strengthening. The thrown pellets and sand particles flow into the steel plate screen at the bottom of the cleaning room through the evenly distributed holes of the rubber crawler. The steel plate screen screens out the steel pellets and fine sand from the larger particles, drops them into the screw conveyor under the screen, and sends them into the elevator, where they are taken to the pellet separator for separation. Dust is sucked to the filter cartridge dust collector by the fan and filtered by the filter cartridge. The clean air emits big air, and the dust on the filter cartridge falls into the dust box at the lower part of the dust collector by pulse back blowing, so that it is cleaned regularly. The old sand flows into the waste sand bucket through the sand flow pipe (provided by the user). The mixture of the larger particles screened by the steel plate in the separator and the unfinished shot sand flows into the cleaning room through the shot pipe. After re-separation, the separated clean shot flows into the shot blasting device again through the shot-flowing pipe to start the shot blasting again.
