Description

本发明涉及机械电器技术,更具体地涉及手持式多用途电动液压机及其专用模夹具。 The present invention relates to electrical machinery technology, and more particularly, to a hand-held multipurpose hydraulic motor unit and the dedicated jig die.

一般的手持式液压机都是手动,在操作时占用两手,因而限制了它的使用范围。 General hydraulic machine is a handheld manual hands occupied during operation, which limits its range of use. 在结构上为了保证初级活塞(即液压柱塞泵活塞)有一定的加压能力,液压柱塞泵的手动杠杆必须保持一定的长度。 In order to ensure that the primary piston structure (i.e., hydraulic ram piston) have a certain ability to pressurized hydraulic manual lever piston pump must maintain a certain length. 因而不可能有效地减轻重量和缩小体积。 It is impossible to effectively reduce the size and weight reduction.

本发明的任务在于提供一种可以单手操作,用电动机驱动的手持式液压机。 Object of the invention is to provide a one-hand operation, the hand-held motor-driven hydraulic machine. 它配以不同的模夹具,可以方便地完成机电工程中多种如冲、拉、压、拔、剪切、挤压、压缩、扩胀、弯曲等加工工艺,并能减轻施工人员的劳动强度,提高工艺质量。 It is accompanied by a different tool holder can be conveniently accomplished in a variety of electrical and mechanical engineering, such as red, pulling, pressing, pulling, shearing, extrusion, compression, bulged, bending and other processing, and can reduce labor intensity of construction workers and improve process quality.

本发明的任务是应用电动机,经减速后直接驱动液压机的柱塞泵柱塞,将工作液压进工作活塞液缸,推动工作活塞作功来实现的。 Object of the invention is the use of a motor, after decelerated direct drive piston hydraulic piston machine, the working piston into the working hydraulic cylinder, pushing a working piston for power to achieve. 根据帕斯卡定律:加在密闭液体上的压强,能够大小不变地被液体向各个方向传递。 Applied to the seal of the liquid pressure can be transmitted to the same size in each direction of the liquid: in accordance with Pascal's law. 因此在液压机上要使工作活塞发出的力大,就要尽可能地加大工作活塞的横截面积,即为F=pS(F:活塞发出的力或受到的力,S:活塞的横截面积,p:液体的压强)。 For the large work force of the piston therefore emitted on the hydraulic machine, it is necessary to increase the cross-sectional area of ​​the working piston as far as possible, that is, F = pS (F: force or by the force of the piston emitted, S: cross section of the piston area, p: the pressure of the liquid). 由于液体是不可压缩的,因而工作活塞的行程等于柱塞泵活塞泵进工作活塞液缸的液体体积除以工作活塞的截面积。 Since the liquid is incompressible, and thus equal to the working stroke of the piston of the piston pump piston into the working volume of the piston cylinder fluid divided by the cross-sectional area of ​​the working piston. 为了保证工作液体能构足够快地泵入工作活塞液缸,柱塞泵活塞的截面积就不能够太小。 In order to ensure that the working fluid pump can be configured fast enough into the working cylinder of the piston, the cross-sectional area of ​​the piston of the piston can be not too small. 但也不能大,如果泵活塞过大,驱动泵活塞的力就要求增大。 But not large, if the piston pump is too large, the driving force of the pump piston requires increased. 在人力一定的情况下就意味着须要加长杠杆,也即意味着要增大液压机的体积和重量。 Means need to lengthen the lever in certain circumstances human, i.e., means increasing the volume and weight of the hydraulic machine. 若泵活塞太小,泵入工作液的时间就要加长,或是泵活塞的工作频率必须加快,这对于人力来说是比较困难的。 If the piston pump is too small, the working fluid is pumped into the time will lengthen, or operating frequency of the pump piston must be accelerated, which for manpower is difficult. 人在连续以80次/分钟的频率摇动手动液压机杠杆,一分钟就有疲劳的感觉。 People continuously at a frequency of 80 times / minute of shaking lever manual hydraulic press, one minute there is a feeling of fatigue. 当然这种疲劳感可以很快消失。 Of course, this fatigue may soon disappear. 人如果以160次/分钟的频率连续摇动杠杆一分钟,所产生的疲劳则必须几倍的时间才能恢复。 If the lever people with continuous shaking for one minute to a frequency 160 times / min, fatigue must be generated several times to recover. 如果人以240次/分钟的频率摇动杠杆,人的注意力已离开了工作目标,而一分钟的疲劳要十几分钟才能完全恢复。 If people shaking lever at a frequency of 240 beats / minute, people's attention has left the objectives, but a minute to fatigue ten minutes to fully recover. 当然用这样的工具是不便工作的。 Of course, the use of such tools is inconvenient work. 本发明根据以上分析,将以手动杠杆驱动的手持式液压机改以电动机驱动。 The present invention is based on the above analysis, the manual lever will be driven to change the hand-held hydraulic motor drive. 由于取消了手摇杠杆,液压机的重量并不须要增加,体积反而可以减少。 With the removal of the hand lever, by weight of the hydraulic machine does not need to increase, but the volume can be reduced. 使用电动机驱动,即使柱塞泵活塞的工作频率再高,对人的工作注意力也不会有影响。 Using a motor-driven, even if the ram piston operating frequency higher, attention to people's work will not be affected. 由于使用电动机驱动,手持式液压机就可以单手操作,这对施工人员来讲是操作的方便,而对完成机电工程加工工艺来讲就是意味着质量的保证。 Due to the use of motor-driven, hand-held hydraulic machine can one-hand operation, which is easy to operate for the staff in terms of construction, electrical and mechanical engineering and processing technology to complete the terms that means quality assurance.

在操作时扳动手持式多用途电动液压机手柄上的电源开关4a,电动机3a立即驱动减速齿轮组3b,使偏心轮3c驱动液压柱塞泵活塞2e在柱塞泵活塞液缸2d里往复运动,柱塞泵活塞2e将从工作液储液囊2k里抽吸到的工作液通过单向液体阀门2h压进工作活塞液缸体2a里,工作活塞液缸里的液体体积增大就迫使工作活塞2b从工作活塞液缸里向外凸出,工作活塞的凸出就使得联接固定在工作活塞液缸上的夹具上的刃具与刃具之间或模具与模具之间产生位移,从而完成工艺任务。 Flipping the power switch on the hand-held multipurpose hydraulic motor operation handle 4a, 3a immediately drive the motor reduction gear set 3B, 3c so that an eccentric drive hydraulic ram piston cylinder 2d 2e ram piston reciprocates inside, 2e ram piston from the working fluid in a reservoir sac 2k drawn into the liquid working fluid through the check valve piston 2h is pressed into the working fluid in the cylinder 2a, the liquid volume of the working fluid tank is increased piston forces the working piston 2b projecting from the working fluid tank piston outwardly convex such that the working piston is coupled to a fixed displacement between the working and the cutting tool on the cutting jig on the piston cylinder and the die or mold, the process to complete the task. 在完成工艺任务后,扳动消压阀扳手4b,由于工作活塞复位弹簧2c的压力,工作液被迫经消压力阀门2i和消压力回油孔2j流回工作液储液囊2k里,工作活塞2b又恢复到原来的位置,以便进行下一次工作。 After the completion of the task process, eliminating pressure valve pulling lever 4b, since the working piston return spring 2c pressure, the working fluid forced through pressure valves 2i and eliminate destructive pressure hydraulic fluid flows back to the oil return hole 2j 2k reservoir bag, the Working 2b piston has returned to its original position, in order to conduct a work under.

在操着时有时会因人的注意力分散等原因,在完成工艺任务后而忘记了关掉电源开关4a,这时工作液体会被继续泵入工作活塞液缸2a,工作活塞2b继续向外凸出,凸出到一定位置,专用模夹具上的定位杆顶动消压力阀门顶开连杆4c,消压力阀门2i被顶开,被泵入的工作液不再推动工作活塞,而由工作活塞液缸经消压力阀门2i和消压力回油孔2j流回工作液储液囊2k。 When speaking person may distraction due to other reasons, the process after the completion of the task and forget to turn off the power supply switch 4a, the working fluid at this time will continue to be pumped into the working cylinder of the piston 2a, 2b continue working piston outwardly projection, projected to a predetermined position, positioning the movable mast eliminate pressure on the tool holder dedicated link 4C valve open top, eliminating the top pressure valve 2i is opened, the working fluid is pumped no longer pushes the working piston, and a work elimination of the piston pressure cylinder via the valve back pressure dissipation hole 2i and 2j balloon back into the working fluid reservoir 2k. 这时电动机3a虽然在驱动液压柱塞泵,而液压机已经停止作功。 Although in this case the electric motor driving the hydraulic piston 3a, the hydraulic machine has been stopped for power. 这不仅保护了模夹具与刃具,而且保护液压机体不会因驱动过量而受到损坏。 This not only protects the tool holder and cutting tool, and will not protect the hydraulic body from being damaged by excessive drive. 为了保护液压机体,还有两项措施可以选择使用。 In order to protect the hydraulic body, there are two measures can choose to use. 一是在工作活塞液缸2a体的一定位置(即工作活塞的最大行程位置),加工一个定位回油孔,与消压力回油孔2j相通,当工作活塞2b到这个位置时,工作液就直接由定位回油孔经消压力回油孔2j流回工作液储液囊2k里,工作活塞2b自然就停止了移动。 First, in a position of the working piston cylinder member 2a (i.e., the maximum working stroke position of the piston), a positioning processing oil return hole, and eliminate back pressure communicating hole 2j, 2b when the operating piston to this position, to the working fluid directly back by the positioning hole with arc into the working line pressure of the oil return hole 2j 2k sac fluid reservoir, the working piston 2b naturally stopped moving. 另一种办法是定量装油法,即工作液储液囊2k里所储的工作液只够将工作活塞2b推到一定位置就没有了,由于液压柱塞泵活塞2e从工作液储液囊2k里抽吸不工作液,液压柱塞泵液缸2d处于真空状态。 Another approach is quantitative oil loading method, i.e., the reservoir fluid in the bladder fluid reservoir 2k only enough working piston 2b is pushed to the predetermined position, there is no, since the hydraulic ram piston 2e from the working fluid reservoir sac 2k where suction is not working fluids, hydraulic piston cylinder 2d in a vacuum state. 液压柱塞泵活塞2e虽有柱塞复位弹簧2g支撑,但由于大气压力的压迫,液压柱塞泵活塞2e不能复位,柱塞泵实际上已与驱动部分脱离接触。 Although a hydraulic ram piston plunger return spring 2g 2e support, but since the atmospheric pressure compression, the hydraulic ram piston 2e can not be reset, and the piston driving section actually out of contact. 整个驱动部分,包括电动机3a,减速传动齿轮组3b和偏心轮3c尽管在继续运转,而液压机一点也不会受到影响或损坏。 Whole drive section includes a motor 3a, 3b and underdrive gearset at the eccentric continues to operate despite 3c, the hydraulic machine would not be affected or damaged.
