Abstract
The utility model provides a changeable-counterweight unloader comprising a slide bar, a weight, a connecting bar, a fixing shaft, and a base. One end of the connecting bar is fixed to the middle of the slide bar. The weight is fixed to one end of the slide bar. The weight and the connecting bar are arranged on the same side of the slide bar. The other end of the connecting bar is connected with the fixing shaft in an articulated manner. A limit block arranged between the connecting bar and the fixing shaft enables the connecting bar inclines to the weight at a certain angle and then stop rotating. The bottom of the fixing shaft is fixed on the base. The weight is fixed to the slide bar through screws and is optionally changeable. The changeable-counterweight unloader has the advantages that the changeable-counterweight unloader is applicable to dies having many trimmed edges and little space, the problem of requiring regulation of various gas circuits is mainly solved, subsequent die regulation time is shorter, the changeable-counterweight unloader is simple and compact in structure and lower in production cost.
Description
Technical field
The invention belong to Auto body panel die design manufacture part field, particularly a kind of changeable counter weight type discharger.
Background technology
In Auto body panel die design manufacture process, when the knife back appears in the layout of counterdie waste knife in deburring technique, face in the situation of the knife back, waste material can be held by the knife back on both sides, cannot rely on deadweight to discharge smoothly mould.Design is in the past that the material supporting rack of air cylinder driven is installed in the middle of the knife back, relies on the Z-direction motion of cylinder that waste material is pressed down.Mainly there are two kinds of defects in design and production method in the past: one, use cylinder, and need to adjust inlet period according to different lathe sources of the gas, very trouble; Its two, cylinder adds material supporting rack, structure is more loaded down with trivial details and uneconomical.
Summary of the invention
This practicality provides a kind of changeable counter weight type discharger for overcoming the above problems, and comprises slide bar, balancing weight, connecting rod, fixed axis, pedestal, and described connecting rod one end is fixed on slide bar middle part; Described balancing weight is fixed on one end of slide bar; Balancing weight and connecting rod are positioned at slide bar homonymy, and the other end and the fixed axis of described connecting rod are hinged and connected, and between connecting rod and fixed axis, exist and prevent that angularity of connecting rod from spending large position limiting structure, and the bottom of fixed axis is fixed on pedestal.
Further described fixed axis is ears ring or monaural ring, and described monaural ring or ears ring comprise ring ear and ring seat, and bolt makes both form articulated structure and can make connecting rod rotate at vertical section through connecting rod and ring ear.
Further described limited block is positioned at fixed axis bottom and after connecting rod, limited block can block connecting rod and prevent its rotation.
Further described limited block is positioned at fixed axis bottom and before connecting rod, limited block can block connecting rod and prevent its rotation.
Further described balancing weight is fixed by screws on slide bar.
Between further described bolt and fixed axis, there is spacer for bolt.
Further described slide bar surface is smooth surface.
Further described pedestal have can with workbench stationary device.
Advantage and good effect that the invention has are: owing to adopting technique scheme, can be more for deburring, the mould of insufficient space, most importantly solve and need not debug various gas circuits, saved follow-up mode transfer time, the invention is not only simple and compact for structure, and has reduced production cost.

The specific embodiment
As shown in Figure 1, the changeable counter weight type discharger of the invention comprises slide bar, balancing weight, connecting rod, fixed axis, pedestal, and described connecting rod one end is fixed on slide bar middle part; Described balancing weight is fixed on one end of slide bar; Balancing weight and connecting rod are positioned at slide bar homonymy, and the other end and the fixed axis of described connecting rod are hinged and connected, and exist limited block that connecting rod is stopped operating after balancing weight direction inclination certain angle between connecting rod and fixed axis, and the bottom of fixed axis is fixed on pedestal.
Further described fixed axis is ears ring or ears ring, and described monaural ring or ears ring comprise ring ear and ring seat, and bolt makes both form articulated structure and can make connecting rod rotate at vertical section through connecting rod and ring ear.
Further described limited block is positioned at fixed axis bottom and after connecting rod, limited block can block connecting rod and prevent its rotation.
Further described limited block is positioned at fixed axis bottom and before connecting rod, limited block can block connecting rod and prevent its rotation.
Further described balancing weight is fixed by screws on slide bar, can freely change.
Between further described bolt and fixed axis, there is spacer for bolt.
Further described slide bar surface is smooth surface.Waste material is more easily slided.
Further described pedestal have can with workbench stationary device.
The course of work of preferred example:
This mechanism has connected balancing weight with screw on slide bar, and slide bar and connecting rod weld together.Because the amount of stressing of balancing weight is large, free state connects under a side direction of balancing weight under the impact of gravity, and opposite side upwards.Due to limited location relation between connecting rod and fixed axis, so mechanism can stop at current state, can because angle is excessive, not cause product to put into.When preorder product is placed on this order mould, because preorder part weight is much larger than balancing weight, one end that slide bar levers up can be depressed.After deburring completes, waste material departs from product, and balancing weight weight is greater than the weight of waste material.Under lever principle, waste material can prolong slide bar swing and drop.Because most main frame producer requires waste material catercorner length to be not more than 600mm, and be generally not more than 4mm after material.Therefore waste material weight is generally not more than 4kg.For the fertilizer of Different Weight, need to change different balancing weights.
