Description
Technical field
The utility model relates to mobile head dummy or sport stroller type bicker.
More specifically, the utility model relates to mobile head dummy cutting machine or Trolley type cutting machine, described cutting machine have be suitable for slip-on head stroke or go-cart automatically and the correction adjustment device, the cutting die of material is carried out punching press, described material comprises materials similar such as leather, synthetic material.
Background technology
In producing, be well known that, use various tool machinery to be used for obtaining successively basic semi-finished product such as the leather and fur products industry of footwear.Particularly in shoemaking industry, a preparation work is a cutting hides, and the each several part leather of making vamp is formed into required length.The cutting of these parts usually uses so-called bicker to finish, and bicker comprises the vertical element that moves, and works in coordination with cutting die and they are stamped on one's body the bottom bed of below.The operator is placed on cutting die and is considered on the leather on the optimal position, and this position changes at any time.Cutting die is made up of the metal framework with cutting edge, and its shape and size depend on half-finished shape of required acquisition.Known bicker comprises different structure types, and wherein two kinds is so-called mobile head dummy and sport stroller type.For the decompressor of cutting die, first type mainly comprises with respect to the bottom lathe bed vertically along the beam column of stretching; Second type, be used for the punching press effect, comprise the go-cart of moving along described beam column.
In both cases, the bottom lathe bed of these bickers is quite wide.
Consider that the linearity of mould moves, is cut the hardness and the thickness of material, the condition of these variations directly influences cutting, particularly beam column or go-cart and acts on pressure on the mould, so the cutting of mould need suitably be proofreaied and correct the pressure that acts on mould.Mould is that the operator selects to be placed on the leather, and its continuous variation should think over, and the linear little mould mould mobile bigger than linearity that move needs less pressure.Therefore consider to make full use of to be placed on bottom bed leather on one's body, can not avoid little mould and big mould are selected, be understandable that timing could be with the mode cutting material of the best at any time to have only pressure when beam column or go-cart, promptly described leather; Otherwise will produce open defect.In fact, if big linearly moving mould is set a suitable force value, then use less mould to make mould penetrate leather easily in this case and be placed on bottom bed Plastic chopping block on one's body.This causes the quick wearing and tearing of described chopping block or breaks, and need carry out expensive and complicated replacing or reparation subsequently.On the contrary, if set a suitable force value, make leather cut not thoroughly usually when then using big mould subsequently, because the gross pressure deficiency for little mould.Necessary repetitive operation this moment, and can usually produce waste material.Another factor that need consider is that bottom bed mould on one's body is in the location that is cut on the leather.If mould is placed on roughly center with respect to beam column or go-cart, if pressure obtains proofreading and correct, then cutting can correctly be carried out.On the contrary,, and for example be placed on the side of bottom lathe bed if mould does not have centering, then pressure beam column or go-cart slight bending, therefore cutting is uneven along whole length, even will produce waste product in this case, perhaps needs to repair to operate.
In the effort that overcomes these shortcomings, known bicker has manual regulating device, so that increase or reduce pressure according to used mould-type and at bottom bed relative position on one's body.The electric hysteresis that changes pressure is operated and formed to these devices generally with knob.The machine hydraulic system do the time corresponding to the big pressure that acts on the mould than the farm labourer, vice versa.This scheme can not guarantee optimum Cutting under various conditions, because these variations and hysteresis are set at any time by the operator.The operator tends to set higher force value easily, thereby can use big mould and little mould to cut; Use little mould above-mentioned shortcoming then to occur, cause the wearing and tearing of chopping block and break, sometimes little mould is except wearing and tearing and tear and also pierce through chopping block the chopping block.
Although operator's SC, the continuous variation of setting with much at one mode generation pressure also needs the long time, thereby has reduced productivity ratio.
