Abstract
The utility model provides a blank shearing device which comprises a fixed mold and a shearing mold, wherein the end faces of fixed mold and the shearing mode are arranged in an attached mode. Through cavities which are communicated are arranged in the fixed mold and the shearing mold, the size of the through cavities are identical with that of the section of a blank, and the shearing mold can move in a plane vertical to the through cavities relative to the fixed mold. According to the blank shearing device, the shearing mold moves in the plane vertical to the through cavities relative to the fixed mold and exerts shearing force on the blank, and the blank is sheared under stress of a vertical direction. The blank shearing device overcomes the defects that a cutting machine is particularly used for shearing the blank in the prior art, efficiency is low, and cost is high and has the advantage of being capable of reducing cost.
Description
Technical field
The utility model relates to mechanical field, in particular to a kind of blank shear.
Background technology
In the prior art, the production and processing technology of small material fin generally all adopts Profile cut-off machine to come the sawing blank to process, and in order to raise the efficiency, guarantees machining accuracy, and the cutting losses part probably accounts for 1/10 of overall spillage of material.Like this, in this road processing technology, be not only and drop into the relatively more expensive cost of cutting machine, and the loss of material also is very surprising.
The utility model content
The utility model purport technical problem to be solved is to provide a kind of blank shear, has solved in the prior art spillage of material many, the problem that production cost is high.
Provide a kind of blank shear at the utility model, comprise fixed die and shearing die, the end face of described fixed die and described shearing die is close to setting, offer the cavity of perforation at described fixed die and described shearing die, described cavity and blank section measure-alike, described shearing die can move in the plane of vertical cavity with respect to fixed die.
Further, described shearing die moves along a straight line.
Further, described fixed die is provided with the clamping part of protrusion, and described shearing die is between described clamping part.
Further, described shearing die is provided with rotating shaft, and described shearing die rotates around the axis.
Further, described fixed die is provided with the stopper section of protrusion, and described shearing die rotates between described stopper section.
Because the blank shear that adopts the utility model to provide, shearing die moves in the plane of vertical blank with respect to fixed die, give blank and apply shearing force, be sheared under the effect of blank stress in vertical direction, utilize blank shear of the present utility model, having overcome needs to use cutting machine to shear specially blank in the prior art, the deficiency that efficient is low and cost is higher, and then reached the technique effect of raising the efficiency the reduction cost.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, consists of the application's a part, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 has schematically shown the blank shear that the utility model embodiment 1 provides;
Fig. 2 has schematically shown the blank shear that the utility model embodiment 2 provides;
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Embodiment 1
A kind of blank shear referring to Fig. 1, comprise fixed die 1 and shearing die 2, fixed die 1 and shearing die 2 surfaces all have the cavity with blank 3 section same sizes, two cavities are installed on the same axis, be that cavity connects fixed die 1 and shearing die 2, make processed blank 3 can smooth and easyly pass into above-mentioned two cavities.The surface of fixed die 1 is protruded and is provided with clamping part 5, shearing die 2 is between clamping part 5, shearing die 2 is under external force with respect to fixed die 1 moving linearly in the direction that clamping part 5 is determined, the installed surface of the direction of motion of shearing die 2 and blank 3 has a certain degree, and can be the angle at 45 ° shown in Fig. 1 direction of arrow.
When shearing die 2 with respect to fixed die 1 moving linearly, the installed surface of the direction of motion and blank 3 has a certain degree, every motion is once reciprocal, a cutting parts is finished.When blank 3 was finished again feeding at previous cutting parts, the part that cuts off was previously released automatically.The length of blank 3 feedings is the design length size of part.
Embodiment 2
A kind of blank shear referring to Fig. 2, comprise fixed die 1 and shearing die 2, fixed die 1 and shearing die 2 surfaces all have the cavity with blank 3 section same sizes, two cavities are installed on the same axis, be that cavity connects fixed die 1 and shearing die 2, make processed blank 3 can smooth and easyly pass into above-mentioned two cavities.The surface of fixed die 1 is protruded and is provided with stopper section 6, shearing die 2 is positioned at the scope that stopper section 6 is determined, shearing die 2 rotates with respect to fixed die 1 by rotating shaft 4 under external force, between the angle that the scope that is rotated in is determined in stopper section 6, the motion direction of rotation of shearing die 2 is shown in Fig. 2 arrow.
When shearing die 2 rotates with respect to fixed die 1, every rotation is once reciprocal, and a part is cut off and finished.When blank 3 was finished again feeding at previous cutting parts, the part that cuts off was previously released automatically.The length of blank 3 feedings is the design length size of part.
As can be seen from the above description, a kind of blank shear that the utility model provides is processed blank 3, not only can remove the Profile cut-off machine equipment cost from, can also reduce the loss of material, saves production cost, enhances productivity.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
