Description
Technical Field
The utility model relates to a mould, in particular to pendulum block adjustment structure.
Background
As a press die, there is a bending die for bending a workpiece at a round angle. When utilizing the mould to bend sheet metal, because the resilience force of material, when the mould of product predetermines the angle and be certain angle, the angle of the product that often obtains after the processing is accomplished will be greater than this and predetermine the angle, has influenced the precision of product processing. Particularly, when a product has a plurality of bends, the precision difference of the product is very large due to tolerance accumulation, and even the assembly of the product is seriously influenced. In the traditional method, in order to solve the problem, the angle of a bending die is designed to be smaller than the preset angle of a product when the die is designed, so that the angle change caused by resilience force is expected to be offset, but the precision and data of the method cannot be calculated, the result is difficult to control, the quality of the product is uneven easily, and the consistency of batch processing of the product is not facilitated. And also requires redesign of the part or mold, which is costly.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a pendulum block adjustment structure.
In order to realize the purpose, the utility model adopts the technical scheme that: the utility model provides a pendulum block adjustment structure, is including fixing the last mould part at punch press top shoe and fixing the lower mould part at mesa under the punch press, it is equipped with adjusting part and swing piece to go up mould part department, the adjusting part has upper and lower reciprocating motion route, swing piece movable assembly forms the revolute pair, the adjusting part is through linking with swing piece butt, be equipped with the elastic component that elasticity resets between swing piece and the last mould part, the portion of bending of swing piece below for cooperating the mould use, it still is equipped with to take off the material and goes into the son to go up the mould part, swing piece is located and is taken off material and goes into son department.
The adjusting piece comprises an adjusting rod and an adjusting punch which are fixedly assembled.
The swing piece comprises a center shaft and a swing block which are movably assembled, and the connecting point of the center shaft and the swing block is positioned between the two ends of the swing block.
At least one end of the swinging block close to the adjusting piece is provided with an abutting inclined surface.
And the abutting inclined plane is provided with an arc-shaped bulge.
The elastic part is a spring, and mounting grooves for assembling the spring are formed in the side wall of the stripping insert and the side wall of the swinging block.
The utility model has the advantages that: the utility model provides a pendulum block adjustment structure is installed in a die, an upper die part is fixed on an upper slide block of a punching machine, a lower die part is fixed on a lower table surface of the punching machine, and when the punching machine moves downwards, an adjustment punch pushes a pendulum block to drive a central shaft to rotate, so that adjustment action is realized; when the punch moves upwards, the adjusting punch moves upwards to separate from the swinging block, and the swinging block resets under the action of the spring force to complete the demoulding action. Simple structure, design practicality reduce product material resilience force through adjustment and buffering, improve the product precision.

Detailed Description
As shown in fig. 1-2, an adjusting structure of a swing block 6 comprises an upper die portion 1 fixed on an upper slide block of a punch press and a lower die portion 2 fixed on a lower table of the punch press, wherein an adjusting piece and a swing piece are arranged at the upper die portion 1, the adjusting piece is provided with an up-and-down reciprocating movement path, and the adjusting piece comprises an adjusting rod 3 and an adjusting punch 4 which are fixedly assembled. In this embodiment, the adjusting rod 3 and the adjusting punch 4 in the adjusting member are in a relatively fixed state, and there is still a space for the adjusting member to move in the upper mold portion 1, so that when the upper mold portion 1 is downward, the adjusting member has a space distance to move relative to the upper mold portion 1 or the swinging member. The relative movement of the adjusting element can be implemented in a wide variety of ways, without being limited to this.
The swinging piece is movably assembled to form a rotating pair, and the adjusting piece is in butt joint linkage with the swinging piece. The swinging piece is a rotatable movable part and comprises a central shaft 5 and a swinging block 6 which are movably assembled, and the connecting point of the central shaft 5 and the swinging block 6 is positioned between the two ends of the swinging block 6. A bending part 7 matched with the die for use is arranged below the swinging piece, the upper die part 1 is also provided with a stripping insert 8, and the swinging piece is arranged at the stripping insert 8. The upper end and the lower end of the swing block 6 which are opposite are two contact ends respectively, and contact different parts.
When the upper die part 1 moves downwards, the adjusting piece moves relative to the upper die part 1 and the swinging block 6, so that the adjusting punch 4 is abutted against the swinging block 6, and the swinging block 6 rotates under the stress. The swinging block 6 and the upper die part 1 clamp the workpiece in a rotating way, and the functions of adjustment and buffering are achieved.
An elastic part 9 for elastic reset is arranged between the swinging part and the upper die part 1, the elastic part 9 is a spring, and mounting grooves 10 for assembling the spring are arranged on the side wall of the stripping insert 8 and the side wall of the swinging block 6. The elastic piece 9 enables the swinging block 6 to gradually return when demoulding, and the clamping force is gradually reduced.
At least one end of the swinging block 6 close to the adjusting piece is provided with an abutting inclined surface 11. The design of the abutting inclined plane 11 is beneficial to smooth contact and abutting in the initial process, and the swinging block 6 is driven to rotate powerfully and efficiently, so that the action sensitivity is improved.
The arc-shaped protrusions 12 are arranged on the abutting inclined plane 11, so that the local structural strength is enhanced, and the service life is prolonged.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, and are only for convenience of description, and are not intended to indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific orientation, and therefore, are not to be considered as limitations of the present invention, and the fundamental principles, main features, and advantages of the present invention have been shown and described above, as would be understood by those skilled in the art.
