Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 As shown, a drawing die structure with adjustable blank-holding force in this embodiment includes a stamping die set on a single-action press, the stamping die includes an upper die base 10 and a lower die base 20, and a drawing die 210 is set On the lower die base 20 , the drawing punch 120 is set on the upper die base 10 , and the upper edge of the upper die base 10 is set above the drawing die 210 .

[0021] Between the upper edge of the upper die base 10 and the drawing die 210, there is also a blank holder 310 arranged sequentially on the upper surface of the product to be processed. A rubber 320 is provided on the blank holder 310, and a rubber 320 is provided above the rubber. The rubber pressing plate 330.

[0022] In this embodiment, during the test, two or more ejector pins 40 for testing are provid...

Abstract

The invention provides a pressure-pad-force adjustable drawing die structure and a usage method thereof. The pressure-pad-force adjustable drawing die structure comprises a punching die arranged on a single-action press. The punching die comprises a drawing female die and a drawing male die which are used for achieving product drawing forming. Clamping devices used for providing product pressure-pad force are arranged on the sides of the drawing female die and the drawing male die. Each clamping device comprises a pressure-pad ring arranged on the upper portion of the edge of a product, wherein a clamping plate is arranged on the pressure-pad ring, a screw fixed to the single-action press penetrates through the middle of the clamping plate, locknuts matched with threads of the screw are arranged at the upper end and the lower end of the clamping plate, the clamping plate is fixed to a transverse translation mechanism capable of driving the clamping plate to move transversely, and the middle of the clamping plate is provided with a slotted hole for giving-way of the screw. The pressure-pad-force adjustable drawing die structure is simple in structure, the product can be tested and perfected conveniently in the drawing procedure, and under the circumstance that a test die meets the standard, the effects that the pressure-pad-force is unchanged and meets product production requirements in the drawing process in product quantity production are ensured.

Description

technical field [0001] The invention relates to a structure of a drawing die with adjustable blank-holding force and a method for using the same. Background technique [0002] In sheet metal deep drawing production, the blank holder force cannot be adjusted when drawing products on a single-action press, and the blank holder force cannot be guaranteed due to parameter changes in mass production after the mold trial, resulting in a large number of drawing waste products, resulting in Huge waste of money. Contents of the invention [0003] The present invention improves the above problems, that is, the technical problem to be solved by the present invention is to design a blank-holding force adjustable deep drawing die structure that meets the requirements of testing and production. [0004] A specific embodiment of the present invention is: the adjustable blank-holding force drawing die structure, including a stamping die arranged on a single-action press, and the stamping...
