一種模具板料活動定位裝置的制作方法

本(ben)實(shi)用新型涉(she)及一種(zhong)模具的板料定位裝置(zhi),尤其是(shi)一種(zhong)模具板料活動(dong)定位裝置(zhi)。



背景技術:

在單工序模具生產(chan)過程中(zhong),板料的定(ding)位(wei)采用外形(xing)固定(ding)式的方式時,經常會遇(yu)到(dao)定(ding)位(wei)太緊或(huo)太松的情況。定(ding)位(wei)太緊產(chan)品(pin)有可能變形(xing),定(ding)位(wei)太松產(chan)品(pin)有可能尺寸(cun)不良。定(ding)位(wei)太松和太緊都(dou)會增加不良品(pin)的數(shu)量。



技術實現要素:

為解(jie)決(jue)上述問(wen)題,本實用新型提供一種能適應(ying)較(jiao)大公差的板料的一種模具板料活動定位裝置,具體技術方(fang)案為:

一(yi)種(zhong)模(mo)具板(ban)(ban)料活動定(ding)(ding)(ding)位(wei)(wei)裝置,包括活動定(ding)(ding)(ding)位(wei)(wei)塊、墊(dian)(dian)板(ban)(ban)、彈簧和(he)固定(ding)(ding)(ding)座;所述(shu)(shu)(shu)活動定(ding)(ding)(ding)位(wei)(wei)塊鉸接在(zai)墊(dian)(dian)板(ban)(ban)的一(yi)端,所述(shu)(shu)(shu)固定(ding)(ding)(ding)座固定(ding)(ding)(ding)在(zai)墊(dian)(dian)板(ban)(ban)的另一(yi)端,所述(shu)(shu)(shu)彈簧一(yi)端固定(ding)(ding)(ding)在(zai)活動定(ding)(ding)(ding)位(wei)(wei)塊上,另一(yi)端固定(ding)(ding)(ding)在(zai)固定(ding)(ding)(ding)座上;所述(shu)(shu)(shu)墊(dian)(dian)板(ban)(ban)固定(ding)(ding)(ding)在(zai)模(mo)座上,且位(wei)(wei)于凹模(mo)的一(yi)端,活動定(ding)(ding)(ding)位(wei)(wei)塊朝向凹模(mo)。

所(suo)(suo)述活(huo)(huo)動定(ding)位(wei)(wei)(wei)塊(kuai)(kuai)朝(chao)向凹(ao)模的(de)端面設(she)(she)有(you)限位(wei)(wei)(wei)凸起,限位(wei)(wei)(wei)凸起位(wei)(wei)(wei)于凹(ao)模的(de)上方;所(suo)(suo)述限位(wei)(wei)(wei)凸起與(yu)活(huo)(huo)動定(ding)位(wei)(wei)(wei)塊(kuai)(kuai)的(de)頂(ding)部(bu)通過導料(liao)斜面連接;所(suo)(suo)述活(huo)(huo)動定(ding)位(wei)(wei)(wei)塊(kuai)(kuai)的(de)底部(bu)設(she)(she)有(you)軸,軸的(de)軸心與(yu)底面的(de)距離(li)不大于軸的(de)半徑;所(suo)(suo)述軸遠離(li)凹(ao)模的(de)一側設(she)(she)有(you)避位(wei)(wei)(wei)斜面。

所述墊板頂部設有(you)與(yu)軸(zhou)相配合的(de)圓柱(zhu)形卡槽,圓柱(zhu)形卡槽的(de)軸(zhou)心(xin)與(yu)頂面的(de)距離不大于圓柱(zhu)形卡槽的(de)半徑。

所(suo)(suo)(suo)述活動定(ding)位塊(kuai)朝(chao)向(xiang)固(gu)定(ding)座的面設(she)有定(ding)位塊(kuai)彈(dan)(dan)簧(huang)(huang)(huang)孔(kong),所(suo)(suo)(suo)述固(gu)定(ding)座朝(chao)向(xiang)活動定(ding)位塊(kuai)的面設(she)有固(gu)定(ding)座彈(dan)(dan)簧(huang)(huang)(huang)孔(kong),所(suo)(suo)(suo)述彈(dan)(dan)簧(huang)(huang)(huang)的兩端分(fen)別固(gu)定(ding)在(zai)定(ding)位塊(kuai)彈(dan)(dan)簧(huang)(huang)(huang)孔(kong)和(he)固(gu)定(ding)座彈(dan)(dan)簧(huang)(huang)(huang)孔(kong)中。

安裝時(shi),將活(huo)動(dong)(dong)定(ding)位(wei)(wei)塊(kuai)朝向(xiang)(xiang)凹模(mo)安裝,活(huo)動(dong)(dong)定(ding)位(wei)(wei)塊(kuai)朝向(xiang)(xiang)凹模(mo)的(de)(de)端面與板(ban)(ban)(ban)料(liao)(liao)重(zhong)合0.5~1.0mm。板(ban)(ban)(ban)料(liao)(liao)由導料(liao)(liao)斜面滑(hua)到限位(wei)(wei)凸(tu)起下方,彈簧將活(huo)動(dong)(dong)定(ding)位(wei)(wei)塊(kuai)壓向(xiang)(xiang)凹模(mo),使(shi)(shi)板(ban)(ban)(ban)料(liao)(liao)壓緊,由于(yu)板(ban)(ban)(ban)料(liao)(liao)與活(huo)動(dong)(dong)定(ding)位(wei)(wei)塊(kuai)有(you)一段重(zhong)合,即使(shi)(shi)板(ban)(ban)(ban)料(liao)(liao)尺寸(cun)偏(pian)小,也(ye)會被(bei)壓緊。由于(yu)活(huo)動(dong)(dong)定(ding)位(wei)(wei)塊(kuai)具有(you)一定(ding)的(de)(de)擺動(dong)(dong)空間,板(ban)(ban)(ban)料(liao)(liao)尺寸(cun)偏(pian)大時(shi),活(huo)動(dong)(dong)定(ding)位(wei)(wei)塊(kuai)向(xiang)(xiang)固定(ding)座方向(xiang)(xiang)傾(qing)斜,使(shi)(shi)板(ban)(ban)(ban)料(liao)(liao)滑(hua)到限位(wei)(wei)凸(tu)起下方。限位(wei)(wei)凸(tu)起可以將板(ban)(ban)(ban)料(liao)(liao)卡(ka)住,防止板(ban)(ban)(ban)料(liao)(liao)脫料(liao)(liao)凹模(mo)。

活動定位塊底部(bu)的(de)軸與墊板的(de)圓(yuan)柱(zhu)形卡槽的(de)接(jie)觸面大于1/2圓(yuan),這樣(yang)活動定位塊不會(hui)從圓(yuan)柱(zhu)形卡槽中滑出。

本(ben)(ben)實(shi)用新(xin)型(xing)提供的(de)一(yi)種模具板料活動定位裝(zhuang)置(zhi)結構簡(jian)單,制(zhi)造成(cheng)本(ben)(ben)低,使用方(fang)便可靠,對板材外(wai)形(xing)尺(chi)寸精度要求低,提高了沖壓(ya)質量(liang),降(jiang)低了成(cheng)本(ben)(ben)。
