托辊装配

Roller assembly

目前托辊装配主要采用专用托辊液压压床来完成。存在的问题是：

The roller assembly mainly adopts roller hydraulic press. The problem is:

1）1个行程，当设备调整好后，只有单独1个行程，压完两端的轴承后，需要把托辊搬运到第二个压床，再压装密封。造成功效低，用人多，产量低。也有把轴承和密封同时一起压装的，这是不合乎工艺要求的，往往产生过压，把密封和轴承过度接触，造成无法转动，不在我们的探讨范围。

1) a trip, after the equipment adjust good, only a trip alone, after pressure at the ends of the bearing, need to turn the roller to the second press, seal installation again. Lead to the low efficiency, more of choose and employ persons, lower productivity. Also have a bearing and seal pressed together at the same time, this is not accord with technical requirements, tend to produce overpressure, the excessive contact seal and bearing, unable to turn, not in the scope of our discussion.

2）调整行程复杂费时。先做大行程粗条，需要松开紧固螺栓，推动机头，然后再调整油缸细扣螺母，用板尺反复测量等等，费工费时，一般的操作工还难以胜任。

2) adjust stroke complicated time consuming. Do big trip cord, first need to loosen the fastening bolts, push the nose, and then adjust the cylinder retaining nut, repeated measurements, etc., with plate ruler takes work, general operator is difficult to do.

3）精度低。往往由于过压装，造成托辊卡转。

3) the low accuracy. Often caused by being connected, roller turn card.

4）液压站处于连续工作状态，消耗能量。

4) hydraulic station is in a state of continuous work, energy consumption.

1.4 托辊喷涂

1.4 roller coating

目前国内国际没有托辊全自动数控喷涂线，虽有个别的半自动喷涂线，往往解决不了托辊的自动吊挂问题，吊挂完全靠人力来完成，1条500支/8小时的喷涂线，需要4-6人完成吊挂；大部分中小企业全手工喷涂。在人力资源紧张、人工费较高的情况下，为了降低制造成本，增强产品的竞争力，实现托辊全自动数控喷涂线成立当务之急。

At present domestic and international not roller automatic nc spraying line, although there are individual semi-automatic painting line, often cannot solve the problem of automatic hanging roller, hanging completely rely on manpower to complete, 1 500/8 hours of painting line, need 4 to 6 people complete hanging; Most of the small and medium-sized enterprises (smes) all hand spraying. Under the condition of the human resources nervous, artificial cost is higher, in order to reduce the manufacturing cost, enhance the competitiveness of the products, realize the roller automatic nc spraying line set up the top priority.
