Description

Mobile head dummy or sport stroller type bicker

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.

Mould is placed on above the leather, in the embodiment shown in Fig. 1 and 2 by beam column 18 direct punching presses, perhaps by the go-cart 20 direct punching presses of Fig. 3 embodiment, the operator uses known device to move described go-cart along described beam column, and go-cart and mould and the oscillating plate 30 that is brought to the bottom cooperate.Use known device to obtain moving both vertically of beam column 18 and/or go-cart 20 with hydraulic way.

According to the utility model, bicker 10,10 ' has the device that is suitable for from dynamic(al) correction or compensation cutting pressure, and cutting pressure is acted on the mould by beam column 18 or go-cart 20.Described automatic calibration or compensation arrangement are made up of at least one pair of device 32, represent this device 32 in Figure 4 and 5 in detail, and the upper end extension of one side is fixed on the bar 26, and opposite side is fixed on the front or the back of beam column 18.What have superiority is, each device 32 comprises the electric contact 34 that is supported on the plate 36, and this electric contact for example is made up of micro switch, and the part of plate 36 usefulness screws 36 ' and so on is fixed on the beam column 18; Between described plate 36 and rod 38, have and contact 34 interactional collar nuts 40.Rod 38 through holes 42 that pass in the beam column 18 have other guiding and centring element near relative upper end, and described guiding and centring element preferably are made up of aperture framework 44, and are fixed on the bar 26 with known device.

On small frame 44, the collar 46 that is connected with knob or handwheel 48 is enclosed within on the rod 38.Utilize the latter, the differing heights position of rod 38 can be fixed and be positioned to the collar 46.

In the latter's upper end, flexible member is housed, for example helical spring 50, and its underpart cooperates with the collar 46, and top is by spring arch clasp (seeger ring) 52 clampings, and ring 52 is in abutting connection with the top of described rod.

Be fixed on shell 54 on the described small frame 44 and cover and protect the upper end of identical rod, have the spring 50 and the collar 46 in the upper end of rod, limit described small frame at least in part.

Autocompensation installation 32 preferably is applied on the bicker 10,10 ', as shown in figs. 1 and 3 in pairs.Because the relative width of the bottom lathe bed 38 of beam column 18 and its below, so mould can be placed on the same lathe bed, thereby and away from the center near shoulder 22 and 24.Therefore even when beam column 18 and/or go-cart 20 were subjected to bending, described device also can guarantee the die-cut of the best.When using the beam column 18 of non-constant width, can consider to use three or more device 32, the suitable distance of each interval.In all cases, be two or more even install 32, they are electric parallel connections, thus cutting pressure can not interrupt, and reaches the respective destinations of stroke up to all said apparatus, and this will be described with reference to its operation below.

Be placed on above the lathe bed 28 of bottom before the material on the chopping block die-cut, according to following pattern and with reference to the height manual adjustments machine 10 or 10 ' of fixed mould.

The operator is placed on a mould on the chopping block, preferably is placed on the center of bottom lathe bed, and in this case, the leather that is cut or other material are not placed on the above-mentioned chopping block.

In order manually to move up and down beam column 18, machine 10,10 ' has known device, and described device is generally driven by handwheel (not shown).The operator reduces beam column by this handwheel, up to beam column, i.e. the oscillating plate 30 of go-cart 20, contact mould and not punching press it.The operator will discharge the handwheel 48 of the rod 38 of retention device 32 earlier.

When beam column 18 or oscillating plate 30 contacts with mould and rod when cooperating with small frame 44, the operator tightens above-mentioned handwheel 48, is fixed on tightly on its position that reaches described excellent 38.Like this, when reducing beam column 18 or go-cart 20 in order accurately to carry out die-cut, the kind of the material that no matter is cut and hardness, the possibility of the linear movement of mould and beam column 18 is crooked, will obtain the precise height scope that beam column 18 or go-cart 20 must reach.

During die-cut, beam column 18 and/or go-cart 20 descend to bottom lathe bed 28, place by the overlapping leather of cutting die on the bottom lathe bed 28.Be a rod 38 after this descends because the reduction of its weight under the gravity effect, or because known thrust device cause excellent reduction.The collar 46 descends, up to arriving the oscillation point that small frame 44 constitutes.Under this condition, the oscillating plate 30 of beam column 18 or go-cart 20 be placed on the mould that will be cut on the leather and cooperate, and collar nut 40 continuous actions are on electric contact 34, the circuit that keep-ups pressure is connected the engine pump of machine opening.With after mould cooperates, beam column 18 or oscillating plate 30 arrive the end of strokes, and carry out another downward constrained motion.Whole motion is corresponding to leather or be cut the thickness of material.This operating period needs the pressure of corrective action on mould, and promptly pressure is all cut described material to wear, and pressure can be excessive be not placed on bottom bed chopping block on one's body and damaged by identical mould to making.Therefore, although there is linear movement in the different moulds that above-mentioned selection is used, still need automatically to proofread and correct this pressure.In this operating period, the beam column 18 that need may not occur when the center mould and/or the bending of go-cart 20 compensate.In order to reach this purpose, because its weight or because the effect of a rod 38 descends and when electric contact 34 is closed, collar nut 40 circuit that stably keep-up pressure in operation are connected on the pump-engine of machine when machine.When beam column 18 or oscillating plate 30 overcame the resistance of cutting material, promptly the lower limb of mould arrived the terminal of stroke and when contact with bottom bed chopping block on one's body, and the small frame 36 of support electric contact 34 is pushed away open loop shape nut 40.Therefore open described contact, and interrupt the pressure of power supply supply or machine circuit.It is because the small frame 36 that supports is fastened on the beam column 18 that described collar nut 40 pushes away electric contact 34, and collar nut 40 is the parts that are fastened on the device 32 of bar 26.Therefore, when the lower limb of mould arrives the terminal of stroke behind cutting material fully and contact on one's body chopping block of bottom bed, electric contact 34 is pushed away collar nut 40, and the opening pressure circuit.This is owing to the rod 38 that supports collar nut 40 when cover 46 contacts small frames 44 can not reduce again.

With thickness, hardness and the beam column 18 of material and/or may crookedly haveing nothing to do of go-cart 20, described circuit keeps connected state substantially, all cuts material until mould.

Can clearly be seen that advantage of the present utility model from top description.

In slip-on head embodiment 10 and sport stroller embodiment 20, because the existence of device 32, it is die-cut that bicker of the present utility model can be carried out accurately and proofread and correct, and do not need operator manual adjustment or setting pressure continuously, in any case and such manual adjustment all is coarse.Cutting can be carried out thoroughly, and needn't worry to cut chopping block, and the possibility of the linear movement of this point and mould, the hardness of material and beam column 18 and/or go-cart 20 is crooked irrelevant.

Although described the utility model with reference to some embodiment, it is not restrictive example that embodiment only is used for explanation, and is noted that one of ordinary skill in the art can make modifications and variations according to foregoing description.Therefore, the utility model comprises spirit and interior variation and the modification of protection domain that all drop on claim.
