具体实施方式
为了使本领域的人员更好地理解本发明，下面结合附图和实施例对本发明进一步说明。显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。在不冲突的情况下，本发明中的实施例及实施例中的特征可以相互结合。
参见图1，本发明实施例提供的一种拉伸机，包括轨道1和设置在轨道1上的两个拉伸头2；所述轨道1上且位于两个拉伸头2之间安装有覆盖板材拉伸长度的至少一组横向矫直辊装置3。
所述轨道1包括两个平行设置的钢轨，用于固定在基础上、以对拉伸头2和横向矫直辊装置3进行安装和支撑。所述轨道1上设置有两个拉伸头2；其中一个拉伸头2拉伸板材时固定在轨道1上，为固定拉伸头；另一个拉伸头2拉伸板材时可在轨道1上移动，为移动拉伸头。不拉伸板材时，两个拉伸头2均可在轨道1上往复移动，两个拉伸头2之间的距离就是板材拉伸长度L；通过控制拉伸头2在轨道1上的位置，就可调节板材拉伸长度L。
所述横向矫直辊装置3安装在轨道1上并位于两个拉伸头2之间，用于在板材5的拉伸过程中对板材5的宽度方向进行矫直；所述横向矫直辊装置3可以包括一组、两组或两组以上。例如，当两个拉伸头2之间设置一组横向矫直辊装置3时，这一组横向矫直辊装置3沿板材拉伸方向4的矫直范围可有效覆盖板材拉伸长度L；当两个拉伸头2之间设置两组横向矫直辊装置3时，这两组横向矫直辊装置3拼装在一起，且沿板材拉伸方向4的矫直范围可有效覆盖板材拉伸长度L；当两个拉伸头2之间设置两组以上横向矫直辊装置3时，两组以上的横向矫直辊装置3拼装在一起，且沿板材拉伸方向4的矫直范围可有效覆盖板材拉伸长度L。所述横向矫直辊装置3可以采用如授权公告号为CN207188511U中的拉伸机矫直小车的结构，也可以采用现有的其他结构，在此不做具体的限定。
本发明实施例提供的拉伸机，通过在两个拉伸头2之间设置覆盖板材拉伸长度的横向矫直辊装置3，能够在板材拉伸全长范围内实时对板材5进行横向矫直，与现有技术相比，无需人工目测板材沿宽度方向的变形情况和变形位置，降低了人工劳动强度，解决了现有技术中由于目测误差而导致矫直质量差的问题，提高了板材5的矫直质量。
参见图2、图3、图4，本发明实施例提供的拉伸机，所述横向矫直辊装置3包括安装在轨道1上的底座31，通过顶升机构32设置在底座31上方的矫直架33，沿板材拉伸方向4均 匀间隔设置在矫直架33上方的至少两个矫直辊34；所述矫直辊34垂直于板材拉伸方向4设置，且其两端分别通过辊座35与矫直架33转动连接。
参见图2、图3，所述底座31放置在轨道1的两个钢轨上；所述底座31沿轨道1延伸方向的两端分别通过防翻装置与轨道1的钢轨连接，以防止底座倾翻。其中，所述轨道1的延伸方向与板材拉伸方向4相一致。所述防翻装置包括两个对称布置在钢轨两侧的防翻板311，并在两个防翻板311的下段之间形成用于与钢轨卡接配合的卡槽，所述钢轨卡接配合在卡槽内，两个防翻板311的上段通过螺栓与底座31固定连接。所述矫直架33设置在底座31的上方，并在矫直架33与底座31之间设置有顶升机构32，利用顶升机构32驱动矫直架33上下运动。参见图3、图4，所述矫直架33的上方设置有至少两个矫直辊34；每个矫直辊34水平设置、且其轴向与板材拉伸方向4相垂直；所述矫直辊34的两端分别通过辊座35与矫直架33转动连接，以使矫直辊34可绕自身轴线转动。所述辊座35可以为带座轴承。所有矫直辊34沿板材拉伸方向4均匀间隔布置，且它们的中心线在同一高度，相邻两个矫直辊34的中心线之间的水平距离为a。每个矫直辊34的长度应大于或等于被矫直的板材5的宽度，以保证每个矫直辊34可在板材5的整个宽度范围对板材5进行矫直。
当所述横向矫直辊装置3中具有N个矫直辊34时，可将所述横向矫直辊装置3简称为N辊装置；其中，N为大于或等于2的整数。参见图1，两个拉伸头2之间设置有四组横向矫直辊装置3，分别是一组二辊装置、一组三辊装置、一组四辊装置和一组五辊装置。
下面结合图1至图4对横向矫直辊装置3的工作原理进行说明。首先，根据板材拉伸长度L，选择四组横向矫直辊装置3安装在两个拉伸头2之间的轨道1上，板材5设置在两个拉伸头2之间；然后通过顶升机构32将矫直辊34顶升至预设高度，使所有横向矫直辊装置3中的矫直辊34的最顶部位于同一高度以形成一个矫直滚动平面，该矫直滚动平面托起的板材5的中心正好与拉伸机的中心重合；当通过两个拉伸头2拉伸板材5时，板材5通过矫直辊34进行支撑，就由原来的悬空拉伸变成在一个滚动平面上拉伸。板材5在拉伸过程中，当板材5沿宽度方向变形时，板材5向下压矫直滚动平面，由于矫直滚动平面不会下降，从而克服了板材5沿宽度方向的变形，达到矫直目的；同时由于矫直滚动平面沿板材拉伸方向4覆盖板材的有效拉伸长度，因而能在板材拉伸全长范围内实时矫直；并且板材5拉伸时，会带动矫直辊34旋转，防止板材5与矫直滚动平面相互滑动，避免板材5表面损伤。
参见图2至图4，本发明实施例提供的拉伸机，所述矫直架33沿板材拉伸方向4的两端分别固定有竖向设置的定位板36；所述定位板36的外表面与最近的矫直辊34中心线之间的距离等于相邻两个矫直辊34中心线之间距离的一半。
所述矫直架33沿板材拉伸方向4的两端分别设置有两个定位板36，两个定位板36沿矫 直辊34的轴向间隔布置。每个定位板36竖向设置，且其背离矫直架33的那个表面为外表面；所述定位板36的外表面与最近的矫直辊34中心线之间的距离为b。所述横向矫直辊装置3中相邻矫直辊34的中心线之间的距离为a。其中，a＝2b。
本发明实施例提供的拉伸机，通过在矫直架33上设置定位板36，当两个拉伸头2之间的所述横向矫直辊装置3包括至少两组时，只需将相邻横向矫直辊装置3中的定位板36的外表面贴靠在一起，就使得相邻两个横向矫直辊装置3中相邻矫直辊34之间的间距c＝2b；这样就可保证任意两个相邻矫直辊34中心线之间的距离相一致。
参见图2至图4，本发明实施例提供的拉伸机，所述矫直架33上安装有位于矫直辊34的下方、并用于对每个矫直辊34支撑的至少一组支撑辊装置37。
所述支撑辊装置37用于对矫直辊34进行支撑；可以采用一组支撑辊装置37对矫直辊34进行支撑，也可以采用两组支撑辊装置37共同对矫直辊34进行支撑，还可以采用两组以上支撑辊装置37共同对矫直辊34进行支撑。本实施例中，每个矫直辊34通过五个支撑辊装置37对其进行支撑，五个支撑辊装置37沿矫直辊34的轴向均匀布置。
参见图4，所述支撑辊装置37包括安装在矫直架33上的支撑架371，安装在支撑架371上并对称布置在矫直辊34两侧的两个支撑辊372。所述支撑辊372通过销轴转动安装在支撑架371上，以使支撑辊372可绕自身轴线转动。所述矫直辊34外周面的下部与支撑辊372的外周面抵接，进而使矫直辊34支撑在支撑辊372上。
参见图5，本发明实施例提供的拉伸机，所述辊座35包括带座轴承351、导向套352、导向块353、拉杆354、压缩弹簧355和挡块356；所述带座轴承351安装在矫直辊34上；所述导向套352设置在带座轴承351的下方并与矫直架33固定连接；所述导向套352内具有竖向设置、且上端开口的导向腔357；所述导向块353滑动配合在导向腔357内、并与带座轴承351固定连接；所述拉杆354设置在导向腔357内，其上端与导向块353固定连接，其下端穿过导向腔357的底壁并与设置在导向套352下方的挡块356固定连接；所述压缩弹簧355设置在导向腔357内并套设在拉杆354上；当所述挡块356在压缩弹簧355的作用下与导向套352的底部抵接时，所述矫直辊34与支撑辊装置37分离。
所述带座轴承351是将滚动轴承和轴承座结合在一起的轴承单元。当将带座轴承351安装在矫直辊34的端部后，使得矫直辊34可相对于带座轴承351绕自身的轴线转动。所述导向块353与所述导向套352的导向腔357为相适配的圆柱形结构；通过将导向块353设置在导向套352的导向腔357内，当导向块353在导向套352的导向腔357内上下移动时，可带动带座轴承351沿竖直方向上下移动，避免带座轴承351发生歪斜。所述导向套352的导向腔357的底壁上设置有供拉杆354穿过的通孔，所述拉杆354的下端从该通孔中穿过并与挡 块356固定连接。优选的，所述挡块356为螺母，该螺母螺纹连接在拉杆354上；这样不仅可使螺母起到止挡的作用，而且还可调节螺母安装在拉杆354上的位置。所述压缩弹簧355设置在导向腔357内并套设在拉杆354上，其两端分别与导向腔357的底壁和导向块353抵接，用于提供的弹簧力。
本实施例中，板材5在拉伸矫直时，两个拉伸头2对板材5施加方向相反的拉力，在该拉力的作用下，板材5向下压矫直辊34，当压力超过压缩弹簧355的弹簧力后，矫直辊34就与支撑辊装置37的支撑辊372接触，并由支撑辊372对其支撑，此时所有矫直辊34的最顶部位于同一高度以形成一个矫直滚动平面，该矫直滚动平面托起的板材5的中心正好与拉伸机的中心重合；这样就通过横向矫直辊装置3对板材5的宽度变形进行矫直。当板材5拉伸矫直后，固定拉伸头2松开板材5，移动拉伸头2带动板材5在矫直辊34上移动，此时板材5对矫直辊34的作用力小于压缩弹簧355的弹簧力，在压缩弹簧355的作用下，矫直辊34与支撑辊装置37的支撑辊372处于分离状态，这样可降低矫直辊34转动时的摩擦力，使得板材5在移动过程中仍然可带动矫直辊34转动，防止板材5与矫直辊34相互滑动，避免板材5表面损伤。
参见图2、图3，本发明实施例提供的拉伸机，所述矫直架33与底座31之间设置有导向装置38；所述导向装置38包括竖向设置的导向轴381，套设在导向轴381上并与其滑动配合的滑套382；所述导向轴381和滑套382分别与矫直架33和底座31中之一固定连接。
本发明实施例提供的拉伸机，通过设置导向装置38，用于对矫直架33在升降过程中进行导向，保证矫直架33沿竖直方向进行运动。本实施例中，所述导向轴381与矫直架33固定连接，所述滑套382与底座31固定连接。在其他实施例中，所述导向轴381与底座31固定连接，所述滑套382与矫直架33固定连接。
参见图2、图3，本发明实施例提供的拉伸机，所述矫直架33与底座31之间设置有两组同步装置39；两组同步装置39沿板材拉伸方向4间隔布置；所述同步装置39包括水平设置并与底座31转动连接的同步轴391，固定在同步轴391两端的齿轮392，固定在矫直架33上并与每个齿轮392相啮合的齿条393。所述同步轴391平行于矫直辊34设置，所述同步轴391通过两个轴承与底座31连接，以使同步轴391可绕自身轴线转动。
本发明实施例提供的拉伸机，当顶升机构32驱动矫直架33上下运动时，矫直架33带动同步轴391上下运动，同步轴391带动齿轮392在与其相啮合的齿条393上滚动，这样就在两套同步装置39的作用下，保证矫直架33的各个位置同步上下运动，避免矫直架33在上下运动过程中出现歪斜的情况，提高了整个装置的可靠性。
参见图2、图3，本发明实施例提供的拉伸机，所述顶升机构32包括至少一个竖向设置 的液压缸；所述液压缸的缸体与底座31连接，液压缸的活塞杆与矫直架33连接。当然，在其他实施例中，所述顶升机构32还可以为气缸或其他直线驱动机构。
所述顶升机构32可以为一个液压缸，也可以为两个或两个以上液压缸。本实施例中，当所述横向矫直辊装置3为二辊装置时，所述顶升机构32包括两个液压缸；当横向矫直辊装置3为三辊装置、四辊装置或五辊装置时，所述顶升机构32包括四个液压缸。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
