Diel is the requisite technological equipment of punching production, is technology-intensive product.The quality of stamping parts, production efficiency and production cost etc., have direct relation with Design of Dies and manufacturing.Its basic parts comprise punch, die and flange fixing installation.

Brake block extension spring connecting bending bar, as a kind of traditional stamping products, is widely used in the automobile production field.Due to the technological deficiency of diel itself, the traditional diamond-making technique of brake block extension spring connecting bending bar is relatively loaded down with trivial details, processing is coarse, and its concrete steps are: first material is heated the pressing and bending moulding; Then the semi-finished product after moulding are heated again, put into the ear tongue on another curved both sides of mould processing.This method easily causes the position height of ear tongue and size to produce larger error, and product quality is very unstable, and the working (machining) efficiency of said method is also lower simultaneously, and the performance of enterprises is poor.

The utility model content

The purpose of this utility model is to provide a kind of production technology simple in order to solve above-mentioned the deficiencies in the prior art, the one-body molded diel of the brake block extension spring connecting bending bar that machining accuracy and production efficiency are high, by the brake block extension spring connecting bending bar of above-mentioned one-body molded Production of Stamping Die, the good stability of its product quality.

to achieve these goals, the one-body molded diel of the brake block extension spring connecting bending bar that the utility model is designed, comprise upper table, lower table, die and upper punch, be fixed with the guiding cylindrical shell below upper table, be fixed with cushion block on the inner bottom surface of guiding cylindrical shell, be provided with flexible member in the guiding cylindrical shell, be connected with the inner surface float plate that work vertically moves back and forth between the opening of cushion block and guiding cylindrical shell that can comply with the cylindrical shell that leads on the outboard end of flexible member, upper punch is fixed on this float plate, also be fixed with wedge below upper table, be fixed with the die that coordinates upper punch and the limited block that is positioned at the die both sides above lower table, be provided with upper table and driven by the wedge below upper table the slide block of doing transverse movement when descending between each sidewall of die and corresponding limited block, and the die of each slide block is equipped with the horizontal drift that can run through die on face.

As preferably, it is external that the utility model provides wedge described in the one-body molded diel of brake block extension spring connecting bending bar to be symmetrically distributed in guide cylinder, and the wedge inclined-plane is towards the outer surface of guiding cylindrical shell, and described slide block is provided with the slide block inclined-plane corresponding with above-mentioned wedge inclined-plane.This preferred version makes the wedge of upper table below can drive slide block and does stably transverse movement.

The one-body molded diel of the brake block extension spring connecting bending bar that the utility model obtains, it has advantages of ear tongue processing on the pressing and bending moulding that can complete brake block extension spring connecting bending bar in same secondary diel and curved, the tradition of comparing needs the brake block extension spring connecting bending bar processing mode of two secondary moulds, by the brake block extension spring connecting bending bar out of one-body molded Production of Stamping Die in the utility model, the error of its ear tongue position height and shape size is little, and constant product quality is high; Simultaneously the production efficiency of enterprise is significantly promoted, energy consumption and cost of human resources decrease.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Embodiment:

As shown in Figure 1, the one-body molded diel of the brake block extension spring connecting bending bar that the present embodiment provides, comprise upper table 1, lower table 2, die 9 and upper punch 8, in actual use, upper table 1 can be in transmission connection with power part, under the effect of power part, upper table 1 can be realized upstream or downstream.be fixed with guiding cylindrical shell 3 below upper table 1, be fixed with cushion block 5 on the inner bottom surface of guiding cylindrical shell 3, cushion block 5 overcoats have spring, be connected with the inner surface float plate 4 that work vertically moves back and forth between the opening of cushion block 5 and guiding cylindrical shell 3 that can comply with the cylindrical shell 3 that leads on the outboard end of spring, upper punch 8 is fixed on this float plate 4, also be fixed with wedge 7 below upper table 1, described wedge 7 is symmetrically distributed in outside guiding cylindrical shell 3, and wedge inclined-plane 7-1 is towards the outer surface of guiding cylindrical shell 3, be fixed with the die 9 that coordinates upper punch 8 and the limited block 10 that is positioned at die 9 both sides above lower table 2, establish slide block 11 is all arranged between each sidewall of die 9 and corresponding limited block 10, be equipped with the slide block inclined-plane 11-1 corresponding with above-mentioned wedge inclined-plane 7-1 on each slide block 11, wedge 7 when upper table 1 is descending below upper table 1 contacts driving slide block 11 and does transverse movement with slide block inclined-plane 11-1 by wedge inclined-plane 7-1, and the die 9 of each slide block 11 is equipped with the horizontal drift 12 that can run through die 9 on face.
