Abstract

The utility model relates to a pair of hand riveting pliers, comprising a handle 1, a handle 2, a riveting knife socket, and a die socket. In the utility model, four connecting rod mechanisms are arranged between the handle 1, the handle 2, the riveting knife socket, and the die socket; a connecting rod 1 is connected with the handle 1 and the handle 2 so as to form a rotating central point A for the handle 1 and the handle 2; a connecting rod 2 is connected with the handles and the riveting knife socket; a connecting rod 3 is connected with the handles and the die socket; a connecting rod 4 is connected with the riveting knife socket and the die socket; the front end of the riveting knife socket is provided with a riveting knife which is the flaky knife; both sides of a knife edge are respectively a curve arc; a matching point between the upper part of the die socket and the riveting knife is provided with a concave hole groove which is formed by two parallel plates; the concave hole groove forms a star shape. Practice proves that the utility model has the advantages of convenient operation, simple structure, and low manufacture cost.

Description

The manual rivet pincers

The utility model relates to a kind of manual rivet pincers, is used for sheet metal, the riveted joint between the thin plate.

The problem that needs riveted joint between the sheet metal is often arranged in the practicality, use rivet and often feel inconvenience, some convenient, practical manual rivet pincers of industrial normal need.

Task of the present utility model is that the manual rivet that proposes no rivet between a kind of sheet metal of practicality clamps.

The technical solution of the utility model is: a kind of manual rivet pincers, handle 1 is arranged, handle 2, the riveted joint tool rest, die socket, handle 1, handle 2, the riveted joint tool rest, die socket, quadric chain is arranged between four, connecting rod 1 links handle 1, handle 2 constitutes the fulcrum A of the two, and connecting rod 2 links handle and riveted joint tool rest, and connecting rod 3 links handle and die socket, connecting rod 4 links riveted joint tool rest and die socket, riveted joint tool rest front end has the riveted joint cutter, and the riveted joint cutter is the sheet cutter, and the blade both sides are curve arcs, die socket top is the spill hole slot that two parallel-plates form with the cooperation place of riveted joint cutter, and it is shaped as

Because the quadric chain that is provided with when closed, makes hard riveted joint cutter incision sheet metal, form and curl, thereby riveted and fixed is finished the invention task.

Fig. 1 is embodiment of the present utility model.

Fig. 2 is riveted joint cutter embodiment.

Fig. 3 is that the K of Fig. 1 is to the termination view.

Be described in detail the utility model below in conjunction with accompanying drawing.

A kind of manual rivet pincers, handle (1) is arranged, handle (2), riveted joint tool rest (3), die socket (4), handle (1), handle (2), riveted joint tool rest (3), die socket (4), quadric chain is arranged between four, connecting rod (12) links handle (1), handle (2) constitutes the fulcrum A of the two, and connecting rod (23) links handle (2) and riveted joint tool rest (3), and connecting rod (14) links handle (1) and die socket (4), connecting rod (34) links riveted joint tool rest (3) and die socket (4), riveted joint tool rest (3) front end has riveted joint cutter (5), and riveted joint cutter (5) is the sheet cutter, and the blade both sides are curve arc (52), die socket (4) top is the spill hole slot (41) that two parallel-plates form with the cooperation place of riveted joint cutter (5), and it is shaped as

Riveted joint cutter (5) is fixed on the front end of riveted joint tool rest (3), and its structure is a sheet riveted joint cutter binding securing member (51), is fastened on the upper end of riveted joint tool rest.The blade hardness of riveted joint cutter (5) is between HRC50～60.

Handle (2) upper end linking part is two laminated plank shapes, and handle (1) and the lower end clamping of riveted joint tool rest (3) are linked by connecting rod (12), (23).

Handle fulcrum A to the normal direction of riveting the cutter center line apart from a and to the air line distance L of handle bottom, relational expression a: L=1 is arranged: 2～3.And the clamping of punch holder lower end links by connecting rod (12), (23), handle (1), handle fulcrum A to the normal direction of drift center line apart from a and to the air line distance L of handle, relational expression a: L=1 is arranged: 2～3, bigger lever ratio is arranged.

During use,, place between riveted joint tool rest (3) and the dimple 40 two thin plates of need riveted joint, holding handle (1), (2) are because the curve arc of riveted joint cutter blade two sides makes thin plate cut the back and rolls up to two springs, thereby crimping tightens together two thin plates, forms no rivet.

Facts have proved that the utility model is easy to use, simple in structure, low cost of manufacture has high practicality and economy.
