[0004] Chinese patent CN102527820 adopts the method of elastic pressing, and adopts more elastic mechanisms, mainly springs. The elastic properties of these springs gradually decrease during regular use, and the product quality of the entire equipment cannot be guaranteed.
[0005] However, if the spring is not used, the tool and the surface of the profile are in rigid contact, it is difficult to ensure the smoothness of the contact surface of the profile, and it is easy to produce wrinkles on the cutting surface, the so-called burrs
[0006] The prior art has not yet provided a tension trimming die that realizes burr-free cutting without the need for an elastic mechanism

Abstract
The invention discloses a farm tool production appliance, in particular to a tensioning trimming die mould. The tensioning trimming die mould comprises an upper pressing plate and a lower bearing table. The lower end of an abutting plate extends out of the upper pressing plate by a distance, and the distance is between one third and one second of the height of the lower bearing table. The inner side surface of the abutting plate is provided with a long strip protuberance in the horizontal direction. The abutting plate is provided with a cutting blade, and the cutting blade is arranged on the connected portion of the against pressing plate and the lower surface of the upper pressing plate. The abutting plate is arranged over an interval between the lower bearing table and an enclosed table of the lower bearing table. The horizontal distance between the inner side surface of the abutting plate and the outer side surface of the lower bearing table is 0.8 times of the thickness of a profile. The height of the protuberance is one third of the thickness of the profile. By the application of the tensioning edge cutting module frame, the defect of unstable product quality caused by decreasing of spring performance in the prior art is overcome, and burr-free cutting on the condition of a spring arranged is achieved.
Description
technical field [0001] 本发明涉及一种农具生产器械,具体涉及一种张紧切边模。 Background technique [0002] 育苗盘作为种植业工厂化育苗重要的载体,在种子育苗过程中对种子的保水、保肥、保温起着关键的作用。在育苗盘的加工过程中需要通过发泡工艺对原材料进行成型加工,然而一开始的成型加工仅是粗步加工,需要对加角作切边处理,才能够算作真正的加工完成。 [0003] 而现有的切边操作,如中国专利CN102527820公开了一种切口光滑的铝合金压铸件切边模,包括上模、下模、设于上、下模之间的导向结构、设于下模的产品定位结构以及设于上模的切边刀口,在下模固定板的下面设有空腔,空腔内设有可上下移动的支撑板,所述支撑板上设有回程杆以及若干用于支撑进料柄的支撑杆,回程杆和支撑杆的上端伸出下模上表面并与下模滑动连接,上模在对应回程杆位置设有压杆,在支撑板和下模的下压板之间设有弹性复位元件。本发明冲切时进料柄始终保持水平状态,使冲切后产品的切口光滑整齐;冲切的同时产品被同步顶出,方便产品取出,可避免产品表面损伤;导柱导套拆装便利,且导柱不易折断。 [0004] 中国专利CN102527820采用弹性压制的方法,采用较多的弹性机构,主要是弹簧,这些弹簧的弹性性能在常期的使用过程中逐渐降低,整个设备的产品品质得不到保证。 [0005] 可是如果不采用弹簧,所述的刀具与型材表在刚性接触,难以保证型材接触面的平整,易在切割面上产生皱褶,即所谓的毛边。 [0006] 现有技术中尚未提供一种在不需要弹性机构的前提下,实现无毛边切割的张紧切边模。 Contents of the invention [0007] 本发明所要解决的技术问题是在不设置弹簧的前提下,实现无毛边切割的张紧切边模。 [0008] In order to solve the above technical problems, the present invention provides the following technical solutions: [0009] 张紧切边模,包括上压板、下承台,其特征在于,所述下承台外围设有一环形的围台,所述围台与下承台的上表面平齐,所述上压板外围设有抵压板,所述抵压板固定在上压板...
