[0001 ]本发明专利申请是申请号:2013100424343,名称:一种免保持式数控转塔冲床的上模,申请日:2013-02-04的分案申请。 [0001] The present invention patent application is application number: 2013100424343, entitled: a no-holding mode CNC turret punch press, filing date: 2013-02-04 a divisional application.

技术领域 FIELD

[0002]本发明涉及数控冲床领域,尤其涉及冲头上模结构的改进。 [0002] The present invention relates to a CNC punch press, and more particularly relates to an improved structure of the die head punch.

背景技术 Background technique

[0003]目前,在冲床,尤其是大型冲床的使用中,上模芯(冲头)的刃口需时常进行打磨以保证加工的精度及效果,这样,就会导致冲头长度的改变;因此,在打磨后,通常需要对其安装高度进行调整;然而,如何简单、有效的对其安装高度进行调整曾一直困扰着本领域技术人员,针对此类问题,国家局于2011年9月28日公布了一份名为“数控冲床模具上模”,申请号为“201120082714.3”的文件,该文件中披露了一种冲头的上模,此类上模中可通过按压锁钩中的钩销与锁芯上的12个等分沟槽相互配合,对锁芯起到锁紧的作用,并在按下按压锁钩时,使得锁芯恢复转动的能力。 [0003] Currently, in the press, especially with large punch, the upper mandrel (punch) is often required for grinding the cutting edge to ensure the accuracy and effect processing, so that it will cause a change in the length of the punch; therefore , after grinding, usually you need to adjust its mounting height; however, how simple and effective for its mounting height adjustment has been plagued skilled in the art, for such problems, the national Council on September 28, 2011 published a report entitled "CNC punch die at the die", application number "201120082714.3" document, this document discloses one kind of the punch die, is pressed by the locking hooks of the hook pin such upper die aliquots cooperate with grooves 12 on the lock cylinder, the key cylinder lock role play, and pressing the locking hook is pressed, so that rotation of the key cylinder capacity recovery.

[0004]然而,上述装置中,仍然存在以下几点问题:一、人们在进行冲头调节时,需将冲头朝上、斜置上模装置于工作台上,并需人工紧紧地压住按压锁钩(如图15所示),其操作难度较大、且危险性较高,特别费力,经常由于手指按压麻木导致上模整体倒下,砸到人的手;二、利用钩销来止转,其可靠性较差;钩销仅靠顶部与按压锁钩连接,却由底部来承受旋转载荷,使得钩销极易发生磨损或断裂,大幅降低了设备的可靠性;三、按压锁钩的装入十分不便,一旦钩销弯曲或断裂,其更换步骤十分繁琐,大幅提升了加工难度在大型设备中;四、12个等分沟槽的间距较大,无法准确的对其安装高度进行控制、调节,大幅降低了其加工精度。 [0004] However, the above-described apparatus, the following problems still exist: a people carrying the ram adjustment, the need to punch head-on, oblique upper mold means on the table, and the need to manually pressed tightly live pressing locking hooks (FIG. 15), the operation difficult, and high risk, particularly laborious, often cause numbness due finger pressing down on the entire mold, hit a person's hand; Second, the use of the hook pin to stop rotation, its reliability is poor; hook lock pin pressing alone and hooking the top, but from the bottom to bear the load of rotation, such that the hook pin prone to breakage or wear, significantly reduce the reliability of the apparatus; three pressing loaded latch hook is very inconvenient, bend or break once the hook pin, which is very complicated replacement procedure that dramatically improves processing difficulty in large plants; four grooves 12 aliquots larger spacing can not be accurately mounted on their height control, regulation, greatly reducing the machining accuracy.

[0021]本发明相对于现有技术改进了锁定装置的结构,改变了现有技术中,在调节上模芯伸出量时,需始终保持人手紧压状态。 [0021] The present invention is improved relative to the prior art structure of the locking device, changes the prior art, when adjusting the projecting amount of the cores, the manpower required to remain pressed state. 启动本发明的免保持式锁定装置后,锁紧轴即被释放,操作人员能够解放其中的一只手,使得两只手均能在模具的上部进行上模芯伸出高度的调节。 After starting the free-retaining locking means according to the present invention, the locking shaft is being released, wherein the operator can liberate one hand, two hands so that the cores can be extended in a height adjustment of the upper mold.

[0022]具体地说:本发明的第一种实施方式,通过弹性球头柱塞和免保持锁定装置中的固定杆可有效夹持锁紧轴,并有效阻止锁紧轴旋转,进而使得冲头在工作时安装高度不会发生变化。 [0022] More specifically: a first embodiment of the present invention, by fixing the locking lever shaft gripping means effective elastic ball plunger and Free remain locked, and effectively prevent the rotation of said mandrel, and further so that the ram head mounted on the working height will not change. 在调整冲头高度时,可向外旋出杆帽,使得固定杆的杆头缩回至小孔一中并与锁紧轴分离,使得锁紧轴可自由旋转;在高度调整完成后,可旋入杆帽,使得固定杆顶住锁紧轴并与弹性球头柱塞同时作用对锁紧轴进行锁紧。 When adjusting the height of the punch, a lever cap can be screwed outward, so that the head is fixed to the rod is retracted and separated from the apertures in a mandrel, the mandrel is free to rotate such that; when height adjustment is completed, a cap screwed rod, so that the fixing rod against the mandrel while the locking effect of the resilient shaft locking ball plunger. 这样,在调整冲头安装高度时,只需通过工具对杆帽进行旋入或旋出,无需持续按住免保持锁定装置,实现了免保持,使其操作十分简单、方便,同时也大幅减少了在调整冲头安装高度时的安全隐患;另一方面,通过固定杆和弹性球头柱塞夹持锁紧的方式,大幅提升了设备的可靠性和安全性。 Thus, when the punch mounting height adjustment, simply by means of the rod cap screwed into or out without having to hold down the free remains locked, allows a free hold, its operation is very simple, convenient, while also significantly reduced adjusting a safety hazard when the punch mounting height; on the other hand, by fixing the ball plunger rod and the elastic clamping locking manner, dramatically improves the reliability and safety of the apparatus.

[0023]本发明的第二种实施方式,通过弹性球头柱塞和免保持锁定装置中的定位杆可有效夹持锁紧轴,并有效阻止锁紧轴旋转,进而使得冲头在工作时安装高度不会发生变化。 [0023] A second embodiment of the present invention, by positioning the mandrel rod holding means effective elastic ball plunger and Free remain locked, and effectively prevent the rotation of said mandrel, thereby making punch in operation installation height does not change. 在调整冲头高度时,可向外拉出拔块并旋转,使得凸脊与长条形凹槽相交错,从而使得定位杆缩回至小孔二中并与锁紧轴分离,使得锁紧轴可自由旋转;在高度调整完成后,可旋转拔块,使得凸脊嵌入长条形凹槽中,从而使得定位杆顶住锁紧轴并与弹性球头柱塞同时作用对锁紧轴进行锁紧。 When adjusting the height of the punch may be pulled outwardly and rotate to pull the block, so that the elongated ridges and grooves are staggered, so that the positioning lever is retracted to the two apertures and separated from the mandrel, so that the locking shaft rotatably; after height adjustment of the rotatable pull block embedded in the ridges such that the elongated recess, so that the positioning rod against the mandrel and simultaneously act on the resilient shaft locking ball plunger locking. 这样,在调整冲头安装高度时,无需持续按住免保持锁定装置,操作十分简单、方便,同时也大幅减少了在调整冲头安装高度时的安全隐患;另一方面,通过定位杆和弹性球头柱塞夹持锁紧的方式,大幅提升了设备的可靠性和安全性。 Thus, when mounting the punch height adjustment, without holding the locking means hold down Free, operation is very simple, convenient, and also significantly reduces security risks when adjusting the mounting height of the punch; on the other hand, by positioning the rod and the elastic ball plungers clamp locking way that dramatically improves the reliability and safety of the device.

[0024]此外,在调整冲头安装高度时,弹性球头柱塞每次从一个凹槽进入下一个凹槽时均会发出一次“嘀嗒”的声响,这样,可根据“嘀嗒”声响的次数来确定锁紧轴的旋转圈数,即上模座和冲头的旋转圈数,结合其旋转圈数和上模座外表面上外螺纹的螺距,即可推算出冲头位移的距离,从而大幅提升了冲头安装时的位置精度。 Will issue a "tick" sound when the [0024] Further, when adjusting the height of the punch mounting, each resilient ball plunger into the recess from one groove to the next, so that, according to the number of available "tick" sound of determining the number of rotations of the mandrel, i.e., the number of the upper die and the punch of rotations, the number of turns in connection with the upper die and the outer surface of the outer thread pitch, to calculate the distance of displacement of the punch, whereby dramatically improves the position accuracy of the punch installation.
