Description

Punch press with fold down formula shifting die arm

Technical Field

The utility model belongs to quick retooling field relates to a punch press with downward folding formula shifting formwork arm.

Background

In machining, it is often necessary to place an extremely heavy mold at the machining station of the press. The mold is typically lifted and placed on a table using a crane and then pushed into the correct position by a worker. The mode has the defects of time and labor waste, inaccurate positioning and potential safety hazard. Therefore, a press with a pattern transfer arm is often used.

The punch press with the shifting die arm can enable the die to be moved and positioned more conveniently and accurately, and the shifting die arm is still fixed on the processing table when the shifting die arm is not needed, so that the space of the processing table is occupied. The detachable shifting formwork arm is time-consuming to disassemble and assemble, and the detachable shifting formwork arm is not convenient enough to carry and store after being disassembled. In view of the above, the present inventors have conducted intensive studies on the above problems, and have made the present invention as to how to construct a punch press with a space-saving and more convenient transfer arm.

The rotating shaft mounting hole is internally provided with a screw which penetrates through the connecting seat and is screwed to hinge the connecting seat and the transfer arm, and the transfer arm can rotate around the rotating shaft mounting hole. And a bolt is inserted into the mounting hole of the control shaft, so that the horizontally placed transfer arm can be fixed. The connecting surface of the connecting seat and the shifting formwork arm is provided with a bulge, the bulge is matched with a concave surface on the shifting formwork arm, and the upper side and the lower side of the concave surface of the shifting formwork arm are clamped with the bulge on the connecting seat. The design of the convex and concave surfaces enables the connection between the connecting seat and the transfer arm to be tighter.

The mould moving arm comprises two metal plates connected by more than two connecting shafts, rolling shafts penetrate through the two metal plates, and idler wheels are sleeved on the rolling shafts. The sliding friction during the design of gyro wheel will move the mould changes rolling friction into, can reduce thrust, and it is more convenient to use. The wear-resistant material on the periphery of the roller can prolong the service life of the transfer arm. The upper surface of the mould shifting arm is flush with the upper surface of the connecting seat. One side of the transfer arm, which is far away from the connecting seat, is provided with a stop block, and the stop block is higher than the upper surface of the transfer arm. The dog can prevent that the mould from dropping, improves production environment's security.

The utility model has the advantages as follows:

the utility model discloses a structure can be by the wide application in production environment such as machining, can improve the security and the convenience of punch press when realizing practicing thrift the space of processing platform.

Detailed Description

The punch press with the downward-folding type shifting die arm shown in fig. 1-4 comprises a punch press body 1 and a shifting die arm 2 connected with the punch press body, wherein a downward-folding mechanism is arranged between the shifting die arm 2 and the punch press body 1, so that the use space of the punch press is convenient to shrink.

The mechanism of rolling over under preferably includes connecting seat 3 as the structure, and connecting seat 3 is the rectangle structure of middle fretwork, and both sides are connected with punch press body 1 and transfer mould arm 2 respectively around connecting seat 3. As an embodiment, the connecting seat 3 is fixedly connected with the workbench 7 on the punch press body 1 through the screw rod in the connecting hole 12, and the upper surface of the connecting seat 3 is flush with the surface of the workbench 7, so that a workpiece can be conveniently pushed into the workbench 7.

The left side and the right side of the connecting seat 3 are provided with oval mounting grooves 4, and a rotating shaft mounting hole 5 connected with the transfer arm 2 and a control shaft mounting hole 6 connected with the transfer arm 2 are formed in the mounting grooves 4. The rotating shaft in the rotating shaft mounting hole 5 transversely penetrates through the transfer arm 2, and the control shaft in the control shaft mounting hole 6 is connected with the transfer arm 2 in a pulling and inserting mode. This kind of structure is taken out and is inserted through the control shaft and connect transfer arm 2, and whether control transfer arm 2 can be rotatory around the rotation axis, also is whether control transfer arm 2 is in operating condition promptly.

For further technical structure be equipped with arch 15 on connecting seat 3 and the shifting formwork arm 2 junction surface, arch 15 cooperation shifting formwork arm on the concave surface 14, the both sides block arch 15 on connecting seat 3 about the concave surface 14 of shifting formwork arm, improve connecting seat 3 and the shifting formwork arm 2 firmness of being connected through the cooperation of arch 15 and concave surface 14, increase the bearing capacity of shifting formwork arm.

The structure of the mould shifting arm 2 is preferably that the mould shifting arm comprises two metal plates 16 connected by more than two connecting shafts 8, a roller 9 penetrates through the two metal plates 16, and a roller 10 is sleeved on the roller 9. One side of the transfer arm 2, which is far away from the connecting seat 3, is provided with a stop block 11, and the stop block 11 is higher than the upper surface of the transfer arm 2. A buffer spring can be arranged on the stop block 11, so that mechanical damage caused by direct collision with the stop block 11 when the die slides is prevented.

Because some dies have larger mass and the high manganese steel material has higher compressive strength, the high manganese steel material can be selected as the wear-resistant material at the periphery of the roller 10.

When the transfer arm needs to be used, the transfer arm 2 hung in front of the punch body 1 rotates around the rotating shaft mounting hole 5 until being flush with the plane of a processing table 7 of the punch body 1, the bulge on the connecting seat 3 is clamped with the concave surface on the transfer arm 2, and the control shaft mounting hole 6 on the connecting seat 3 and the transfer arm 2 are aligned. The insert pin rear mold-moving arm 2 is fixed in a horizontal state. The worker uses a traveling crane to place the mold on the transfer arm 2 and push it along the transfer arm 2 to a suitable position of the press working table 7. And after the processing is finished, the die is taken down, and if the die shifting arm is not needed to be used any more, the plug pin passing through the control shaft mounting hole 6 can be pulled out. At this time, the transfer arm 2 is folded down and hung in front of the punch body 1 according to the action of gravity.
