Description

Porous clamping of small-size mold insert of stamping die

Technical Field

The utility model relates to the technical field of tool clamps, in particular to a porous clamping device for a small insert of a stamping die.

Background

At present, the design of the insert structure of the automobile stamping die is limited by space to a large extent, and the designed shapes, structures, hole pitches and other types are different. The single insert processing has the characteristics of independence, variability and the like, so the single insert is not easy to clamp during processing, and a plurality of tools with different types and sizes are required to lock the insert. The traditional clamping modes generally comprise two modes, namely vice clamping and backing plate locking clamping. Both clamping modes have disadvantages.

1. In the machining process of the insert clamped by the vice, lateral force generated by the cutter and the insert easily causes dislocation of the insert, and the bottom surface moves or tilts, so that the machining precision is affected.

2. The insert which is locked on the backing plate for processing is relatively high in stability in the processing process, but the selected backing plate is various in variety and easy to interfere with a processing cutter, and a process plate is required to be corrected after clamping each time, so that the clamping efficiency is low.

Disclosure of Invention

The utility model provides a porous clamping device for a small insert of a stamping die, which aims to overcome the defects of the prior art.

In order to achieve the above purpose, the multi-hole clamping of the small insert of the stamping die is designed, comprising a process plate, and the multi-hole clamping is characterized in that: the process plate on be equipped with a plurality of screw holes, process plate one side is equipped with T type groove, the distance in screw hole and T type groove centre bore increases gradually, is equipped with square nut in the T type groove.

One side of the screw hole is carved with a hole pitch value.

One side of the process plate, which is close to the screw hole, is provided with a cutter avoiding surface.

Lifting holes are formed in two ends of the process plate.

The T-shaped groove is provided with bolt holes on two sides of the end far away from the screw holes.

One side of the bolt hole is connected with an anti-falling bolt.

Compared with the prior art, the utility model utilizes the characteristic that the porous process plate can flexibly adjust the position, realizes the rapid clamping and locking of the inserts of different types on the same process plate, solves the problem that the small insert of the automobile stamping die is difficult to independently process and fix, effectively solves the problem that the processing is dry and involves the stress relief of the insert by utilizing the characteristic that the small insert can be flexibly adjusted, and improves the processing efficiency and accuracy.

Referring to fig. 1 to 4, wherein 1 is a process plate, 2 is a screw hole, 3 is a pitch value, 4 is a T-shaped groove, 5 is a bolt hole, 6 is an anti-falling bolt, 7 is a lifting hole, 8 is a tool avoidance surface, 9 is a square nut, 10 is an insert, 11 is an insert fixing locking screw hole, 12 is an insert fixing locking square nut hole, and 13 is a side trimming edge.

Detailed Description

The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1 to 4, the process plate 1 is provided with a plurality of screw holes 2, one side of the process plate 1 is provided with a T-shaped groove 4, the distance between the screw holes 2 and the central hole of the T-shaped groove 4 increases gradually, a square nut 9 is arranged in the T-shaped groove 4, the square nut 9 is placed in the T-shaped groove 4, an insert 10 to be processed is placed, and an insert fixing locking screw hole 11 and an insert fixing locking square nut hole 12 on the insert 10 are used for respectively locking the square nuts 9 in the upper screw hole 2 and the T-shaped groove 4 of the process plate 1 by bolts for quick clamping.

One side of the screw hole 2 is carved with a hole pitch value 3, and an operator can quickly find the screw hole 2 to be locked according to the hole pitch of the insert 10 to be processed by utilizing the hole pitch value 3 carved on the process plate 1, so that quick clamping is realized.

The side of the process plate 1, which is close to the screw hole 2, is provided with a cutter avoiding surface 8, and when a cutter edge 13 is repaired at the machining side, a cutter can be avoided by machining with a machine tool 3+2 side head, so that machining interference is avoided.

Lifting holes 7 are formed in the two ends of the process plate 1, and a lifting function can be achieved.

The T-shaped groove 4 is provided with bolt holes 5 on two sides of the end far away from the screw holes 2 for locking the anti-falling bolts 6.

One side of the bolt hole 5 is connected with an anti-falling bolt 6, and two sides of the end head of the T-shaped groove 4 are locked by the anti-falling bolt 6, so that the square nut 9 is prevented from falling off in the using process.
