Abstract

The utility model discloses a cutting die of U-type channel steel, comprising an upper die part, a lower die part, a bottom plate, a cushion plate and a positioning part, wherein the upper die part comprises a die handle and a pressing plate below the die handle; the lower die part comprises a movable concave die which can move along the vertical direction and a fixed concave die which is fixedly connected with the cushion plate; the movable concave die and the fixed concave die are adjacent and are provided with channel steel cavities which are positioned at the same height and penetrated by a U-type channel steel working piece; the lower part of the movable concave die is provided with an elastic part; the pressing plate of the upper die part is contacted with the upper surface of the movable concave die when falling off; and the positioning part is positioned at the front of the running of the U-type channel steel working piece. The cutting die of the U-type channel steel adopting the structure can greatly improve the working efficiency of blanking of the U-type channel steel; and the end surface of the working piece for blanking is smooth and does not need post processing, thus reducing working load of workers and manufacturing cost.

Description

A kind of U type channel-section steel knife edge die

Technical field

The utility model relates to cold punching die, relates in particular to a kind of U type channel-section steel knife edge die.

Background technology

Usually cutting machine or sawing machine are adopted in the cut-out of U type channel-section steel, the sawing machine baiting method needs the sawing machine equipment of a special use when producing in batches, not only the time of blanking cost more, and sawing can produce iron filings, the waste raw material, U type channel-section steel end face produces more burr under the saw blade effect; Cutting machine baiting method U type channel-section steel end face also can produce iron filings under the saw blade effect, the burr of generation is bigger, needs subsequent treatment, and workman's workload is bigger, and existing cutting machine or sawing machine baiting method all can cause the consume of cutting blade, have strengthened cost of manufacture.

The utility model content

Technical problem to be solved in the utility model is: a kind of U type channel-section steel knife edge die is provided, and the use of this kind U type channel-section steel knife edge die has not only reduced the cost of manufacture of U type channel-section steel blanking, and has reduced workman's workload.

Solve this technical problem, the technical solution of the utility model is: a kind of U type channel-section steel knife edge die, it comprises upper mold portion, lower mold portion, base plate, backing plate and keeper, upper mold portion comprises the pressing plate of die shank and die shank below, lower mold portion comprises adjacent movable matrix that can vertically move and the fixedly die affixed with backing plate, described movable matrix, fixedly die has the channel-section steel die cavity that the U type channel-section steel workpiece that is positioned at sustained height passes under normal conditions, the bottom of described movable matrix has elastomeric element, contact with the upper surface of movable matrix when the pressing plate of described upper mold portion falls, described keeper is positioned at the place ahead of U type channel-section steel workpiece operation.

Described elastomeric element comprises return spring and the caging bolt that contacts with the movable matrix lower surface.

Described movable matrix the and fixedly side of die is other is respectively arranged with first guide plate and second guide plate, described first guide plate and second guide plate have the channel-section steel die cavity that U type channel-section steel workpiece passes.

Described first guide plate, movable matrix, fixedly the opening direction of the channel-section steel die cavity of die, second guide plate is downward-sloping miter angle.

A kind of U type of the utility model channel-section steel knife edge die adopts such structure, the operating efficiency of U type channel-section steel blanking is increased substantially, the workpiece end face of blanking is smooth, do not need subsequent treatment, reduced workman's workload, adopted the blanking of U type channel-section steel knife edge die, die-cut no waste material and need not cooling fluid, avoid cutting machine or sawing machine blanking to the consume of cutting blade, reduced cost of manufacture.
