Description

An adjustable tray receiving mechanism for punching dies

technical field

The invention belongs to auxiliary equipment for die safety production, and in particular relates to an adjustable tray-connecting mechanism for upper and lower dies.

Background technique

At present, most of the punching dies for the upper and lower parts adopt the operation method of two people, single strokes and manual unloading. Not only is the production efficiency low, but the most important thing is that it is unsafe for the operator. The operator puts his hand, arm, head, etc. into the dangerous area to complete the stamping work , prone to safety accidents.

Contents of the invention

In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide an adjustable tray-connecting mechanism for the punching die of the upper ejection, which has the advantages of high production efficiency and high production safety.

In order to achieve the above object, the technical scheme that the present invention takes is:

An adjustable plate receiving mechanism for the punching die, which is symmetrically arranged on both sides of the mold, each side includes an upper connecting rod 3, and one end of the upper connecting rod 3 is movably connected to the upper die base 1 through the first pin 2 One end of the upper and lower connecting rods 5 is connected with the other end of the upper connecting rod 3 through a rectangular groove opened on the upper connecting rod 3, and is fastened by the first nut 4;

One end of the lower swing link 10 is movably connected to the lower mold base 12 through the third pin 11, and one end of the upper swing link 8 is connected with the other end of the lower swing link 10 through a rectangular groove opened in the lower swing link 10, and is tightened by the second nut 9. solid;

The other end of the lower link 5 and the other end of the upper swing link 8 are flexibly connected by the second pin 7 fixed on the upper swing link 8;

The connecting plate 13 is fixed on the upper swing rod 8 , the screw rod 14 is fixed on the connecting plate 13 , the connection plate 6 is sleeved on the screw rod 14 through the groove 16 opened thereon, and is fixed by the third nut 15 .

Working principle of the present invention is:

When the upper mold goes up, the first pin 2 drives the upper link 3 to move upward, and at the same time drives the integrated upper link 3 and lower link 5 to swing into the mold around the first pin 2, and the lower link 5 moves inward. While swinging, the second pin 7 drives the upper swing rod 8 to swing into the mold, and the connecting plate 6 fixed with the upper swing rod 8 swings into the mold at the same time. When the upper die rises to the position of the upper dead point, the connecting plate 6 Swing to the horizontal position, at this time, the feeding mechanism will knock down the workpiece located in the die hole of the die in the upper die, and the receiving plate 6 will catch the workpiece dropped from the die hole of the die;

When the upper mold goes down, the first pin 2 drives the upper connecting rod 3 to move downward, and at the same time drives the connected upper connecting rod 3 and lower connecting rod 5 to swing out of the mold around the first pin 2, and the lower connecting rod 5 moves toward the mold. While swinging outward, the second pin 7 drives the upper swing bar 8 to swing out of the mold, and the connecting plate 6 fixed with the upper swing bar 8 swings out of the mold at the same time, when the upper mold drops to the position of the bottom dead center, and The receiving tray 6 fixed by the upper swing rod 8 swings out of the mold and tilts, and the workpiece in the receiving tray 6 slides into the collector along the inclined surface.

Since the present invention changes manual unloading into mechanical splicing, on the one hand, it not only guarantees the synchronization with the production efficiency of the workpiece structurally, but also completely eliminates the possibility of safety accidents from the structural point of view, which is beneficial to the improvement of operation It has practical significance to improve the labor intensity and environment of the operator, and to improve productivity, so it has the advantages of high production efficiency and high production safety.

FIG. 2 is a schematic diagram of connection between the connecting plate 6 and the lower swing link 8 of the present invention.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings.

Referring to Fig. 1, it is an adjustable connecting plate mechanism for the upper output punching die, which is symmetrically arranged on both sides of the mold, each side includes an upper link 3, and one end of the upper link 3 is movably connected to the upper part through the first pin 2 On the mold base 1, the upper connecting rod 3 can rotate around the first pin 2, and one end of the lower connecting rod 5 is connected with the other end of the upper connecting rod 3 through a rectangular groove opened on the upper connecting rod 3, and is tightened by the first nut 4. solid; changing the position of the lower connecting rod 5 in the upper connecting rod 3 can change the length of the entire connecting rod to adapt to different mold opening heights;

One end of the lower swing link 10 is movably connected on the lower mold base 12 through the third pin 11, the lower swing link 10 can rotate around the third pin 11, and one end of the upper swing link 8 passes through the rectangular groove opened in the lower swing link 10 and the bottom of the lower swing link 10. The other end is connected and fastened by the second nut 9; by changing the position in the groove, the purpose of changing the length of the entire pendulum is achieved to adapt to different mold opening heights;

The other end of the lower link 5 and the other end of the upper swing link 8 are movably connected by the second pin 7 welded on the upper swing link 8, and the lower link 5 can rotate around the second pin 7;

Referring to Fig. 2, the connecting plate 6 and the upper swing rod 8 are connected, the connecting plate 13 is welded on the upper swing rod 8, the screw rod 14 is welded on the connecting plate 13, and the connecting plate 6 is sleeved on the screw rod 14 through the groove 16 opened thereon , and fixed by the third nut 15.

Working principle of the present invention is:

After each stamping operation is completed, the workpiece is extruded into the die hole of the die located in the upper die. At this time, the upper mold goes up, and the upper connecting rod 3 is driven upward by the first pin 2, and at the same time, the upper connecting rod 3 and the lower connecting rod 5 which are connected as one are driven to swing into the mold around the first pin 2, because the lower connecting rod 5 and the lower connecting rod 5 The upper swing link 8 is connected by the pin 7 welded on the upper swing link 8, while the lower link 5 swings into the mold, the second pin 7 drives the upper swing link 8 to swing in the mold, and the upper swing link 8 is fixed on the The joint plate 6 swings into the mold at the same time. When the upper die rises to the position of the upper dead point, the joint plate 6 swings to the horizontal position. Catch the workpiece that falls in the die hole of the die.

When the upper mold goes down, the first pin 2 drives the upper connecting rod 3 to move downward, and at the same time drives the integrated upper connecting rod 3 and lower connecting rod 5 to swing out of the mold around the first pin 2, because the lower connecting rod 5 and the lower connecting rod 5 The upper swing rod 8 is connected by the pin 7 welded on the upper swing rod 8, while the lower connecting rod 5 swings out of the mold, the second pin 7 drives the upper swing rod 8 to swing out of the mold, and the upper swing rod 8 is fixed on the The connecting plate 6 together swings out of the mold at the same time, allowing the space for the upper mold to go down. When the upper mold drops to the position of the bottom dead point, the connecting plate 6 fixed with the upper swing rod 8 swings out of the mold and tilts. The workpiece slides into the collector along the inclined surface, and at the same time, the next blanking work is performed.
