目前, 在国内所有生产铜类产品的厂家, 铜带刷洗工艺、 结构形式效仿相 同, 铜带在刷洗的过程中都存在相同的问题, 主要是刷铜带所用的钢丝刷不可 能制做的十分精确, 钢丝刷在运转时产生径向跳动和偏摆, 对铜带被刷洗表面 的质量产生很大影响, 现在铜带刷洗补助机构形式是处于静止的结构, 铜带托 架滑块曝露在刷洗过程粉尘中, 造成滑块没有滑动性, 推动滑块弹簧损去作用, 随钢丝刷质量因素而变化, 不可能保证铜带表面刷洗质量。 At present, in all domestic manufacturers of copper products, the copper strip brushing process and structural form follow the same pattern. The copper strip has the same problem in the process of brushing, mainly because the wire brush used for brushing the copper strip cannot be made very much. Accurate, the wire brush generates radial runout and yaw during operation, which has a great influence on the quality of the copper belt being brushed surface. Now the copper belt brushing auxiliary mechanism is in a static structure, and the copper belt bracket slider is exposed to the brush. In the process dust, the slider does not have sliding property, and the slider spring is destructed, which varies with the quality factor of the wire brush, and it is impossible to ensure the quality of the surface of the copper strip.
发明内容 Summary of the invention
本发明为了解决上述传统技术中存在的问题, 通过大量的试验和不断的探 索, 提供了一种铜带刷洗自动调整装置, 解决了现有技术中刷洗铜带时, 钢丝 刷在运转时容易产生径向跳动和偏摆的问题; 而且降低了生产成本, 延长了铜 带使用寿命, 提高了刷洗条件, 保证了铜带质量。 In order to solve the problems in the above conventional techniques, the present invention provides a copper belt brushing automatic adjusting device through a large number of tests and continuous exploration, which solves the problem that the wire brush is easy to be generated when the copper wire brush is brushed in the prior art. Radial runout and yaw problem; and reduce production costs, extend the life of the copper strip, improve the brushing conditions, and ensure the quality of the copper strip.
为了实现上述目的, 本发明的技术方案如下: In order to achieve the above object, the technical solution of the present invention is as follows:
滑座的内部设置滑柱, 滑柱的内部安装有弹性件, 滑柱内部的弹性件与滑 座上的调整螺杆相结合; 滑柱的顶端设置托架, 托架的上方设置托板, 托架与 托板之间设置垫块。 A sliding column is arranged inside the sliding seat, and an elastic member is installed inside the sliding column, and an elastic member inside the sliding column is combined with an adjusting screw on the sliding seat; a bracket is arranged at a top end of the sliding column, and a supporting plate is arranged above the bracket, A spacer is placed between the frame and the pallet.
所述的滑柱的外部设置有防尘外套, 防尘外套与滑座形成半封闭状态。
所述的滑柱上设置导槽, 导槽与滑座之间安装限位螺钉。 The outer part of the sliding column is provided with a dustproof outer casing, and the dustproof outer casing and the sliding seat form a semi-closed state. A guide groove is arranged on the sliding column, and a limiting screw is installed between the guide groove and the sliding seat.
所述的垫块为钢球, 设置在同一条中心线上。 The spacers are steel balls and are disposed on the same center line.
所述的弹性件与调整螺杆之间设置弹性托垫。 An elastic support pad is disposed between the elastic member and the adjusting screw.
所述的滑座的下端连接有基座支架。 The bottom end of the sliding seat is connected with a base bracket.
本发明的优点效果如下: The advantages and disadvantages of the present invention are as follows:
1、 本发明滑座内的滑柱通过调整螺杆、 弹簧、 使滑柱产生一定的弹性, 来 消除钢丝刷的径向跳动自动补偿。 1. The sliding column in the sliding seat of the invention automatically adjusts the radial runout of the wire brush by adjusting the screw and the spring to make the sliding column have a certain elasticity.
2、 托架紧固在滑柱中, 托架内在一条中心线的两端分别装有两个钢球, 托 起铜带垫板一定的距离, 消除了钢丝刷的偏摆度。 2. The bracket is fastened in the sliding column. Two steel balls are respectively installed at two ends of a center line in the bracket to support the copper belt backing plate to a certain distance, thereby eliminating the deflection degree of the wire brush.
3、 滑柱上的防尘外套与滑座形成半封闭状态, 防止了在刷洗过程中粉尘进 入滑柱中, 使滑柱能始终保持良好的滑动性。 3. The dustproof jacket on the spool and the sliding seat form a semi-closed state, which prevents the dust from entering the sliding column during the brushing process, so that the sliding column can always maintain good sliding property.
4、 通过滑座上的限位螺钉, 滑柱导槽, 使托限上面在一个方位上, 由于托 架内两个钢球支点和滑柱中弹簧的双层作用, 促使铜带托板托起铜带并与钢丝 刷直面接触。 4. Through the limit screw on the sliding seat and the sliding guide groove, the bracket is placed in one orientation. Due to the double action of the two steel ball fulcrums in the bracket and the spring in the spool, the copper belt support is promoted. The copper strip is brought into direct contact with the wire brush.
5、 铜带在通过本发明装置将钢丝刷转速调整到慢速时, 可明显的观察到, 滑柱钢球上的铜带托板, 随钢丝刷的径向跳动和摆动而变化, 在实施的过程中, 使用本发明, 常期连续刷洗铜带表面以证明了本发明对铜带刷洗过程中的稳定 性, 本发明是针对上述钢丝刷不可避免的质量问题设计的。 通过实践以证明, 铜带刷洗过程中无局部过热现象产生的氧化和刷洗不均的问题, 本发明完全附 合铜带表面刷洗工艺质量要求。 5. When the copper strip is adjusted to a slow speed by the device of the present invention, it can be clearly observed that the copper strip on the steel ball of the strut changes with the radial runout and swing of the wire brush. In the process of using the present invention, the surface of the copper strip is continuously brushed continuously to prove the stability of the present invention in the brushing process of the copper strip. The present invention is designed for the inevitable quality problem of the above-mentioned wire brush. Through practice, it proves that there is no problem of oxidation and brushing unevenness caused by local overheating during the brushing process of the copper strip, and the present invention fully complies with the quality requirements of the surface scrubbing process of the copper strip.
