Description
Technical Field
The utility model belongs to the technical field of stamping dies, and particularly relates to a floating limiting device for a blank holder.
Background
The drawing and punching process of the spoke comprises the processes of forward extending, inverse drawing, shaping, punching, trimming, punching bolt holes, extruding spherical surface flanging and the like. The purpose of these procedures is to achieve the specified dimensional tolerances and shapes of the spokes and to ensure their surface quality. After the drawing and punching process is finished, a product deviation phenomenon occurs due to deformation, and the product deviation can cause abnormal grabbing of a workpiece by a manipulator, so that the production efficiency is seriously affected.
Disclosure of utility model
The utility model aims to solve the technical problems that: overcomes the defects existing in the prior art and provides a blank holder floating limiting device.
The technical scheme for solving the technical problems is as follows: the blank holder floating limiting device comprises a blank holder, wherein a floating positioning structure is clamped on the periphery of the blank holder, square stock is placed on the top of the floating positioning structure, the floating positioning structure is completely covered by the square stock, and the square stock is stretched and deformed into a molding square stock.
Further, the floating positioning structure comprises a limiting column and a spring, wherein the spring is placed at the bottom of the limiting column, and the limiting column is clamped inside the blank holder.
Further, the square stock covers at blank holder top, and the square stock pushes down the spacing post through gravity this moment, and the spring is in the state of compressing tightly simultaneously.
Further, the forming square stock is sleeved with the blank holder, at the moment, the floating positioning structure is restored to an initial state, and the spring upwards bounces the limit column; and four corners of the formed square stock are clamped between the limiting columns.
Compared with the prior art, the utility model has the beneficial effects that: the floating positioning structure is added on the blank holder of the original drawing and punching die, so that the processing cost is low, the product deviation phenomenon is effectively solved, the limiting effect on the formed square stock is achieved, and the production efficiency is obviously improved.

Detailed Description
The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.
The floating limit device of the blank holder comprises a blank holder 1, wherein a floating locating structure 2 is clamped in the circumferential direction of the blank holder 1, the floating locating structure 2 comprises a limit column 21 and a spring 22, the spring 22 is arranged at the bottom of the limit column 21, and the limit column 21 is clamped inside the blank holder 1. Square stock 3 has been placed at the floating positioning structure 2 top, and floating positioning structure 2 is covered by square stock 3 is complete, and square stock 3 tensile deformation becomes shaping square stock 4.
The square stock 3 covers at blank holder 1 top, and square stock 3 pushes down spacing post 21 through gravity this moment, and spring 22 is in the state of compressing tightly simultaneously. Square stock 3 is placed at the top of blank holder 1, guarantees simultaneously that square stock 3 covers at spacing post 21 top, and square stock 3 pushes down spacing post 21 top surface to flush with blank holder 1 top surface through weight, and spring 22 is the shrink state simultaneously
The forming square stock 4 is sleeved with the blank holder 1, at the moment, the limiting column 21 is sprung upwards by the spring 22, when the square stock 3 is stretched into the forming square stock 4, the size is reduced along with the material flowing in the forming process, the limiting column 21 is not covered any more, and the floating positioning structure 2 is restored to the initial state; four corners of the formed square stock 4 are clamped between the limiting columns 21, so that the limiting columns 21 play a limiting role.
Principle of operation
During operation, square stock 3 is placed on the top of the blank holder 1, meanwhile, the square stock 3 is ensured to cover the top of the limiting column 21, the top surface of the limiting column 21 is pressed down to be flush with the top surface of the blank holder 1 by the square stock 3 through weight, and meanwhile, the spring 22 is in a contracted state; when the square stock 3 is stretched into the formed square stock 4, the size is reduced along with the material flowing in the forming process, the limit posts 21 are not covered any more, the spring 22 upwards bounces the limit posts 21, the floating positioning structure 2 is restored to the initial state, four corners of the formed square stock 4 are clamped between the limit posts 21, and the limit posts 21 play a limit role.
The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the utility model are intended to be included within the scope of the utility model.
