Description

冲压装置和多通道罐盖冲压系统 技术领域
本申请涉及一种易拉罐盖制造设备，特别是涉及一种冲压装置和多通道罐盖冲压系统。
背景技术
目前市场上基础盖系统最快产能已经达到9000盖/分钟左右(四通道)，而组合冲速度最快只有3000盖/分钟，效率难以满足市场需求。
而为了进一步提高效率，设备的紧凑度、冲压精度以及稳定性是难以克服的问题。
另外，结合图1a和图1b所示，在传统手段中，卷边完成的盖体501在通过上模502和下模503冲压加工时，需要借助于活动结构的定位杯504，通过定位杯可以提前对盖子进行矫正位置，从而起到定位效果。但是因为模具排布的原因，空间紧凑，使用定位杯结构对拆装模具增加难度。
发明内容
本申请的目的在于提供一种冲压装置和多通道罐盖冲压系统，以克服现有技术中的不足。
为实现上述目的，本申请提供如下技术方案：
本申请实施例公开一种冲压装置，用于多个产品盖的同时冲压，包括阵列设置的多个冲压模组，

具体实施方式
下面将结合附图对本申请的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在本申请的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
结合图1c所示，本申请的实施例提供一种多通道罐盖冲压系统，包括输送组件1、下盖组件2和冲压组件3。
本实施例中以6通道冲压结构进行举例说明，需要说明的是，本案冲压系统同样适用于6通道以上的系统，由于结构原理类似，本案不再重复赘述。
输送组件1设置于下盖组件2的下方，用以将来自下盖组件2放置的盖体传送至冲压组件3的加工工位。
输送组件1包括并列设置的两条同步带11，同步带11的两端分别通过皮带轮12进行传动。
每条同步带11上分别开设有3列盖体定位孔111。每个定位孔111分别用以对应一个盖体，同步带在水平方向移动过程中，可以带动盖体同步移动至加工工位。
进一步地，为了使得定位孔111更加紧凑，降低同步带的宽度，每条同步带上，相邻列的定位孔111沿输送方向交错设置。
易于想到的是，输送组件1也可以仅仅设置一条较宽的同步带，同步带上直接设置6列定位孔，但是该实施例会带来成本增加等问题，并非本案优选方式。
结合图2至图4所示，下盖组件2包括一支撑板201以及固定于该支撑板201上表面的6个分盖器202。
支撑板201水平支撑于两条同步带11的正上方，每个分盖器202分别对应于同步带上的一个盖体定位孔111。
六通道的输送盖同步带，因为排布紧凑以后，孔与孔(盖体定位孔)间距变小，强度变弱，同步带涨紧后孔变形量会加大。
为了确保在同步带发生孔变形的情况下，分盖器仍然可以和盖体定位孔对准，结合图2所示，本实施例中的每个分盖器202在水平面内位移独立可调。
结合图3所示，每个分盖器202分别包括基座2021、落盖筒2022和2个分盖轮2023，落盖筒2022和分盖轮2023设置于基座2021上，2个分盖轮2023对称设置于落盖筒2022的两侧。
进一步地，位于支撑板201上的所有分盖轮2023(12个分盖轮)通过同一条皮带2023传动连接。
定义水平面的XY坐标系，每个分盖器202分别在X方向和Y方向位移独立可调。
进一步地，X方向垂直于盖体定位孔111成列的方向。
结合图4所示，基座2021的侧方设置有调节装置2024，通过调节装置2024可以实现基座2021在X方向或Y方向的移动。
调节装置2024包括多个分布于基座2021四周的调节螺杆，支撑板201上配合调节螺杆安装有定位块2025。当需要调节基座特定方向的位移时，转动基座位于该方向两侧的调节螺杆，使得调节螺杆顶住定位块2025实现基座2021的X方向或Y方向的移动。
该技术方案中，通过独立可调的分盖器结构，每组分盖器的基座前后、左右方向均可调节。这样方便每一组分盖器对准同步带定位孔调节。
结合图5和图6所示，冲压组件3包括阵列设置的多个冲压模组31，每个冲压模组31分别包括上模311和下模312。
结合图8所示，在优选的实施例中，冲压组件3包括2个模具a，每个模具a集成有3列下模312，使得每个模具a形成3个通道结构b，每个通道b上对应阵列分布多个下模312，该多个下模312线性排列，每个下模312分别与同步带上的一个定位孔对应。
上模311和下模312分别形成于同步带11的上下方，上模311和下模312接近可对同步带11上的产品盖4进行冲压。
产品盖4的形成过程，一般是先将金属料材经基本盖冲床冲压形成一个个基本盖，再经卷边机卷边、注胶机注胶后，由烘干机烘干，获得的具有卷边的产品盖4通过冲压模组31进一步加工。
冲压模组31在对具有卷边41的产品盖4进行冲压时，需要对卷边进行定位。由于本实施中冲压模组31并列设置有6个通道，为了保持其紧凑，冲压模组31在并列安装后应尽量避免拆卸。
为解决该问题，本实施例中，上模311一体成型，且上模311的外径大于下模的外径，上模311的底端边缘构成了卷边41的定位部。
结合图6所示，上模311和下模312均具有圆柱形的主体部，上模311和下模312同轴设置，在上模311和下模312接近并形成挤压后，上模311的边缘凸伸于下模312的顶端四周，且上模311的下边缘R角与卷边41的顶 面相抵持，并构成环形接触定位。
在优选的实施例中，上模311的下边缘具有弧形的倒角。
该实施例中，取消了可活动的定位杯结构，可以避免因六通道结构紧凑、无法拆装模具的难度，同时采用直接增加上模直径的方式，不仅避免了定位杯的拆卸，还能实现产品盖定位的效果。
结合图7所示，上模311和下模312在长期使用过程中，其预设的间隔容易发生变化，为了对该间隔进行可控调节，本实施例中下模312的上表面高度可调。
进一步地，下模312支撑于一可调组件313上，可调组件313包括可热胀冷缩的加热器组件3131。
加热器组件3131可以采用具有稳定的线膨胀系数的金属材料。
该技术方案中，加热器组件3131连接有热电偶3132，通过热电偶控制温度，使加热器组件上下膨胀、收缩来控制模具整体的高度，达到精确、迅速控制产品的参数目的。
在优选实施例中，加热器组件3131形状与下模312匹配，均采用圆柱形，在热胀冷缩过程中，形变的发生主要体现在高度方向。
为了避免加热器组件3131的热量向下传递，加热器组件3131的下表面贴合有一隔热垫片3133。
在优选的实施例中，隔热垫片3133采用隔热陶瓷垫片。
在其他实施例中，只要能满足隔热、低热膨胀系数即可。
在一实施例中，加热器组件3131和下模312之间还可以设置有上垫片3134。
进一步地，上垫片3134为金属垫片。优选为钢制垫片。
该技术方案中，上垫片3134也可以为陶瓷垫片，但是陶瓷材料成本高，而且加热器组件3131上面陶瓷垫片在拆装模具过程中容易损坏。
经过试验测试，本实施例用钢质材料取代了陶瓷垫片，同样能够达到使用效果，而且避免了零件经常性损坏。
本实施例中的6通道冲压系统，相对于4通道系统，可以将组合冲的速度提高到4500盖/分钟，同时将产能提高了50％。
综上所述，本申请技术方案适用于6通道以及6通道以上的冲压系统， 为了保证其紧凑性，本案通过三方面的改进以实现其综合性能的提高：一方面对基座进行改进以使得每个基座位移独立可调；另一方面，取消了上模上的定位杯结构；再一方面，在下模上设置了可热胀冷缩的高度调节结构。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
