Definitions
- the invention relates to the technical sector of tooling and in particular impact tools such as in particular the punch pins.
- guards made in the form of a flange or cup having a central opening allowing the engagement of the tool and attaching to it using lips capable of engaging in a circular flange or groove. formed on the tool body. This type of guard has the sole function of ensuring the protection of the user's hand.
- the gripping device adapting to striking tools of the type comprising a plastic sleeve engaging the body of the tool is remarkable in that it comprises a plastic sleeve having flexibility in its structure, and comprising a plurality of ring shapes, of large diameter, interconnected by connecting shapes of smaller section defining a bellows and corrugation structure, and in that, at the place of each ring is provided with a circular internal projection bearing against the body of the tool, and in that the sleeve has at least one internal flange capable of engaging and clipping inside at least one groove circular formed in the tool body.
- Figure 1 is a view of the device before mounting according to the invention adapted on a striking tool called "pin punch”.
- Figure 2 is a view after assembly according to Figure 1 of the device during the striking operations.
- Figure 3 is a sectional view along line A-A of Figure%.
- Figures 4 and 5 are views showing the compression and elongation deformation of the sleeve relative to its state in the event of non-stress.
- the device according to the invention is designed and produced in the form of a sleeve (1) of plastic material having a flexibility in its structure to allow its deformation.
- This sleeve is established over a long length and it comprises along it a plurality of ring shapes (1 .1) of large diameter joined together by connecting shapes (1 .2) of smaller section, the assembly defining a bellows structure with undulations.
- a circular internal projection (1 .3) capable of coming to bear against the body of the tool.
- These circular projections are established of a certain thickness and in particular greater than the depth of the above-mentioned connecting zones (1.2) which are not in contact with the body of the tool.
- At least one inner flange (1 .4) is provided which is capable of engaging and clipping inside at least one circular groove (2.1) formed in the body (2 ) of the tool. This lip-forming flange is clipped into the groove, thus ensuring perfect hold of the device.
- the device according to the invention by its structure and its shapes, allows the bellows effect the absorption of shocks due to the striking forces by causing the deformation of the sleeve either by elongation or by compression, and by sliding on the tool body.
- the sleeve has in its head part a protective shape of the hand of the user, having an appropriate diametral section to ensure such a function.
- said head may have a complementary bonding zone with the front part of the striking tool, opposite its useful zone of contact with the part to be struck.
- the sleeve may have, over all or part of its length, a granite coating obtained by soaking in an appropriate bath.
- the sleeve according to the invention can be applied to any striking tool, such as a pin punch or the like, chisel or other, and be of any section in diameter and length.
