Abstract

The utility model relates to a feeding and discharging mechanism outside a pressing machine. The feeding and discharging mechanism comprises a mold, supporting devices and a jacking device, wherein the supporting devices are located below two sides of the mold, a groove is formed between the supporting devices on the two sides, the jacking device is arranged in the groove, an ejector rod penetrating through the mold in an up-and-down mode is arranged in the mold, and the ejector rod can move upward and downward along with the jacking device. According to the feeding and discharging mechanism, when the size of a workpiece is large or an opening stroke of the pressing machine is not sufficient, feeding and pick-up can be achieved outside the pressing machine. When the mold is in a feeding and discharging position, the feeding and pick-up can be achieved conveniently, and production efficiency and product quality are improved.

Description

The outer charging and discharging mechanism of a kind of forcing press
Technical field
The utility model relates to a kind of charging and discharging mechanism, relates in particular to the outer charging and discharging mechanism of a kind of forcing press.
Background technology
Forcing press is a kind of versatility forcing press of delicate structure.Have characteristics such as of many uses, production efficiency height, forcing press can be widely used in technologies such as cut-out, punching, blanking, bending, riveted and shaping.Make metal generation plastic deformation and fracture be processed into part by metal blank being applied powerful pressure.Drive big belt pulley (double as flywheel usually) by motor by V belt during punching machine work, drive slider-crank mechanism, make slide block and punch straight line descending through gear pair and clutch.It is up that punching machine is finished the rear slider journey in forging and pressing work, and clutch is thrown off automatically, and the automation on the crank axle is connected simultaneously, and slide block is stopped near the top dead centre.
Existing pressure processing mould generally all is the Working position material loading in forcing press, also takes out workpiece in this position after the processing.But, the machine opening stroke that perhaps is stressed when restriction, at the Working position material loading with take out very difficulty of workpiece, even may sometimes when workpiece size is very big.
The utility model content
Technical problem to be solved in the utility model provides the outer charging and discharging mechanism of a kind of forcing press, make mould can be forcing press outside material loading and taking-up workpiece.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: the outer charging and discharging mechanism of a kind of forcing press, comprise mould, bracing or strutting arrangement and jacking apparatus, described bracing or strutting arrangement is positioned at the below of mould both sides, between described supported on both sides device, be provided with groove, described jacking apparatus is located in the groove, be provided with the push rod that runs through mould up and down in the described mould, described push rod can move up and down with jacking apparatus.
The beneficial effects of the utility model are: when very big or forcing press opening stroke is not enough when workpiece size, can realize material loading and pickup outside forcing press.When mould is in the loading and unloading position, material loading and pickup easily, improve production efficiency and product quality.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described jacking apparatus is by a plurality of hydraulic cylinders and be connected piston rod on the hydraulic cylinder and arrange and to constitute, and described piston rod part and push rod bottom shape structure match, and can move up and down synchronously.
The beneficial effect that adopts above-mentioned further scheme is that jacking apparatus adopts a plurality of hydraulic cylinders, and hydraulic cylinder quantity and position and ejector pin of die set are complementary.When hydraulic cylinder jack-up piston rod, thereby during the jack-up push rod, can make the workpiece demoulding; When hydraulic cylinder descended, piston rod descended, and push rod is caught the blank realization material loading in the mould that falls back.
Piston rod during the demoulding on the hydraulic cylinder stretches out, and with the push rod jack-up of mould, makes workpiece break away from mould, continues jacking, and the location of workpiece improves, and obtains enough spaces and makes crane gear can take workpiece away.When hydraulic cylinder rose to the extreme higher position with push rod, crane gear placed blank on the push rod, and push rod support blank descends with hydraulic cylinder piston rod, fell in the mould blank and the location, realized material loading.
Description of drawings

Fig. 2 is the utility model jacking apparatus structural representation;
Fig. 3 is the utility model workpiece demoulding schematic diagram;
Fig. 4 is the utility model blank material loading schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
As shown in Figure 1, the outer charging and discharging mechanism of a kind of forcing press, it is characterized in that, comprise mould 1, bracing or strutting arrangement 2 and jacking apparatus 3, described bracing or strutting arrangement 2 is positioned at the below of mould 1 both sides, is provided with groove 4 between described supported on both sides device 2, and described jacking apparatus 3 is located in the groove 4, be provided with the push rod 5 that runs through mould 1 up and down in the described mould 1, described push rod 5 can move up and down with jacking apparatus 3.
When very big or forcing press opening stroke is not enough when workpiece size, can outside forcing press, realize material loading and pickup.When mould 1 is in the loading and unloading position, material loading and pickup easily, improve production efficiency and product quality.
As shown in Figure 2, described jacking apparatus 3 is by a plurality of hydraulic cylinders 6 and be connected piston rod 7 on the hydraulic cylinder 6 and arrange and constitute, and described piston rod 7 tops and push rod 5 bottom shape structures match, and can move up and down synchronously.
Identical circle or rectangle can be adopted with the horizontal cross-section at push rod 5 tops in described piston rod 7 bottoms, and be positioned at same position on the vertical plane, the contacted position in described piston rod 7 bottoms and push rod 5 tops shape and structure matches, can be zigzag engagement or arc and cooperate, it is interrupted to guarantee that like this two moves up and down synchronously.
As shown in Figure 3 and Figure 4, described jacking apparatus 3 adopts a plurality of hydraulic cylinders 6, and the push rod 5 of hydraulic cylinder 6 quantity and position and mould 1 is complementary.When hydraulic cylinder 6 jack-up piston rods 7, thereby during jack-up push rod 5, can make workpiece 8 demouldings; When hydraulic cylinder 6 descended, piston rod 7 descended, and push rod 5 is caught the blank 9 realization material loading in the mould 1 that falls back.
Piston rod 7 during the demoulding on the hydraulic cylinder 6 stretches out, and with push rod 5 jack-up of mould 1, makes workpiece 8 break away from mould 1, continues jacking, and improve workpiece 8 positions, obtains enough spaces and make crane gear can take workpiece 8 away.When hydraulic cylinder 6 rose to the extreme higher position with push rod 5, crane gear placed blank 9 on the push rod 5, and push rod 5 support blanks descend with the piston rod on the hydraulic cylinder 67, fall in the mould 1 blank 9 and the location, realize material loading.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
