Detailed Description

The following describes a jig for a punch press according to the present utility model by way of examples with reference to the accompanying drawings.

Referring to fig. 1 to 4, the utility model provides a clamp for a punch press, which comprises a holding rod 1, a pressing rod 2 movably arranged on the holding rod 1, a torsion spring 3 arranged on the holding rod 1 and elastically connected with the pressing rod 2, and a fast-assembling magnetic attraction structure 4 arranged on the pressing rod 2, wherein the fast-assembling magnetic attraction structure 4 comprises a connecting column 41 arranged on the pressing rod 2, a magnetic block 42 arranged on the connecting column 41, and a fast-assembling structure arranged on the connecting column 41 and fast-assembling with the pressing rod 2, and a through hole 21 is arranged on the pressing rod 2; the fixture can replace two hands to place the workpiece on the punch press, and can also take the workpiece out of the punch press, so that the direct contact between the two hands and the punch press is avoided, and the safety of an operator in using the punch press is improved; through the setting of fast-assembling structure, when the magnetism of magnetic path 42 disappears and need change, only need pass new spliced pole 41 through-hole 21, utilize the joint mode to fix spliced pole 41 on pressing pole 2 can, easy operation is convenient.

The holding rod 1 is provided with a sleeve 11 which is in the same plane with the end face of the magnetic block 42, the connecting column 41 is provided with a spacer sleeve 43 matched with the magnetic block 42, the quick assembly structure comprises an extrusion slot 411 arranged on the connecting column 41, an elastic clamping strip 412 which is arranged on the extrusion slot 411 and is in limit locking with the pressing rod 2, the elastic clamping strip 412 is provided with a clamping block 413 matched with the end face of the pressing rod 2, and the clamping block 413 is provided with a guide inclined plane 414; by the arrangement of the guide inclined plane 414, when the connecting column 41 is assembled, the elastic clamping strip 412 is better inserted into the through hole 21 under the action of the guide inclined plane 414, so that the installation is convenient; through the arrangement of the sleeve 11, the end surfaces of the sleeve 11 and the magnetic block 42 are positioned on the same plane, the workpiece can be quickly separated from the magnetic block 42 through the isolation sleeve 11 when the pressing rod 2 is pressed while the adsorption of the magnetic block 42 to the workpiece is not influenced, and the operation is simple and convenient; through the setting of spacer 43, wrap up the outer lane of magnetic path 42, prevent that magnetic path 42 from taking place magnetism with pressing rod 2 or holding rod 1 and inhale and unable normal use in the use, promote the usability of anchor clamps.

In the use of the utility model, the fixture is moved to the upper part of the workpiece, the end face of the magnetic block 42 is contacted with the workpiece, so that the workpiece is adsorbed on the fixture by the magnetic block 42, then the fixture is moved to a die of a punch press, at the moment, the pressing rod 2 is pressed to enable the pressing rod 2 to squeeze the torsion spring 3, the magnetic block 42 is driven by the pressing rod 2 to lift upwards from the sleeve 11, the workpiece is limited by the sleeve 11 and separated from the magnetic block 42, so that the workpiece is placed on the die, the punch press is started to punch the workpiece, and after the punching is finished, the workpiece is taken out by adopting the same method.

When the magnetism of the magnetic block disappears and needs to be replaced, the guide inclined plane 414 is squeezed by fingers, the guide inclined plane 414 is squeezed to drive the clamping block 413 to incline towards the inner side of the squeezing slot 411, and simultaneously the elastic clamping strip 412 is driven to incline inwards, and at the moment, the connecting column 41 is pushed out of the through hole 21, so that the connecting column 41 is quickly separated from the pressing rod 2; when the new connecting column 41 is inserted into the sleeve 11 and passes through the through hole 21, and the guide inclined plane 414 contacts the through hole 21, the guide inclined plane 414 is extruded by the through hole 21, the clamping block 413 is driven to incline inwards by the guide inclined plane 414, and meanwhile the elastic clamping strip 412 is driven to incline inwards, so that the clamping block 413 rapidly passes through the through hole 21, the guide inclined plane 414 is not extruded after the clamping block 413 passes through the through hole 21, the elastic clamping strip 412 clamps the clamping block 413 on the end face of the through hole 21 by means of resilience force, and the connecting column 41 is mounted on the pressing rod 2, so that rapid replacement is realized.

The above embodiments are illustrative of the present utility model, and not limiting, and any simple modifications of the present utility model fall within the scope of the present utility model.
