Clamping die device

Abstract

The invention discloses a clamping die device. The clamping die device comprises a mounting plate, an air cylinder and a set of clamping dies, wherein each clamping die is provided with an upper die base and a lower die base, and the clamping dies are mounted on the mounting plate. The clamping die device further comprises a connecting rod assembly, and the connecting rod assembly comprises firstswing arms, second swing arms and a first connecting shaft; the first ends of the first swing arms and the first ends of the second swing arms are pivotally connected with the first connecting shaft and can rotate around the first connecting shaft, the second ends of the first swing arms and the second ends of the second swing arms are installed on the mounting plate separately and can rotate, thefirst swing arms and the second swing arms are provided with pressing blocks respectively, and the pressing blocks abut against the upper surfaces of the upper die bases; and a piston rod of the aircylinder is connected with the first connecting shaft and can drive the first connecting shaft to reciprocate up and down, the first swing arms and the second swing arms are driven to swing accordingly, and in the swing stroke of the first swing arms and the second swing arms, the pressing blocks complete the action of releasing or pressing the upper die bases. The clamping die device has the advantages that the acting force range of the air cylinder is large, the application range is wide, the acting effect is good, and the cost is low.

Description

technical field [0001] The invention relates to the field of clamping devices, in particular to a clamping device. Background technique [0002] At present, the structure of the clamping device of the cutting machine is as follows: figure 1 As shown, it specifically includes a support table 900, a cylinder 100, a clamping mold 200, and a connecting plate 300. The first surface of the connecting plate 300 is installed on the piston rod end of the cylinder 100 and is driven to reciprocate by the piston rod. The clamping mold 200 includes an upper The clamping die 201 and the lower clamping die 202 matched with the upper clamping die 201, the upper clamping die 201 is installed on the second surface of the connection plate 300, and the piston rod of the cylinder 100 drives the connection plate 300 to reciprocate up and down, thereby driving the upper clamp The mold 201 reciprocates up and down to open or close the clamping mold 200, so as to realize the loosening and clamping ...

Problems solved by technology

[0003] However, in the mold clamping device of the above-mentioned prior art, the force effect of the cylinder 100 in this design is poor, and the force range is small. For clamping molds that require a larger thrust, a cylinder with a greater thrust is needed, or even a cylinder with a greater thrust is required. Increase the cylinder to achieve

Therefore, this design cylinder in the prior art has a small force range, narrow application range, poor effect and high cost
