Description

Automatic laterally centering perforating die

Technical field

This utility model is related to Stamping Die Technology field, more particularly to a kind of automatically horizontal centering perforating die.

Background technology

Leaf spring is the main flexible member of automobile suspension system, and domestic and international all types of goods vehicles are used at present Suspension system is still based on Leaf Spring Suspension, and leaf spring is generally needed in leaf spring in process per a piece of The centre bore of end all cross machines of middle part and part piece, in order to the assembling of leaf spring and alligator clamp, leaf spring is horizontal Generally there are punching and drilling to the processing mode of centre bore, punching is generally directed to relatively thin plate spring sheet and is generally less than 16mm, at present Mainly with side position punch, during punching, employee needs to promote plate spring sheet to make plate always with handss the punch pattern of domestic leaf spring Reed side is positioned against die side, shakes larger during punching, and employee's operation comfort is poor；Using punching gland discharging, when will When different width leaf springs are processed in punching, the gland of correspondence width need to be changed, and die change is cumbersome；Because leaf spring reed is former The width tolerance of material is larger to be usually B ± 0.8mm (B be reed width) and punching technology requires that the horizontal tolerance in hole is ± 0.8, This causes to want Jing often to measure the tolerance of plate spring sheet raw material to adjust punch press side position location in the course of processing, causes drilling precision The high labor intensive and inefficiency of not high, workman, increased many defects such as production cost.

Utility model content

For the problem that prior art is present, this utility model provides a kind of automatically horizontal centering perforating die, to solve In the leaf spring course of processing, during punching, employee's operation comfort is poor, not high, workman work is strong to adjust mould time length, precision Degree is big and inefficiency, the problems such as production cost is excessive, improves punching production efficiency, improve the processing essence of the horizontal tolerance of punching Degree, further improve product quality.

The technical scheme in the invention for solving the technical problem is：Automatic laterally centering perforating die, including it is upper Template, lower template, horizontal positioning device, lateral positioning device, longitudinal positioning device, elastic tripper, drift, guide pillar and bottom Mould, horizontal positioning device include two locating wheels, and lateral positioning device includes clamp locating piece and clamp bolt, and longitudinal direction is fixed Position device includes that than chi and locating piece guide pillar includes lower guide pillar and guide column sleeve, and bed die is located at the central authorities of lower template, locating wheel and folder Hoop locating piece is located at cloth in lower template, and, around bed die, longitudinal positioning device is located at the left-side center of lower template, and guide pillar is located at down Connect upper die plate on rear side of template, upper die plate central authorities are provided with elastic tripper, and drift is located at the middle position of elastic tripper； Automatically laterally centering perforating die is respectively to arrange a locating wheel in plate spring sheet two ends appropriately distance, when rushing the plate spring sheet of different in width Change the locating wheel of correspondence diameter；Lateral positioning device is used when transverse center pitch-row is close to plate spring sheet termination, mould is fixed Position mode changes easy to adjust；During punching, employee is firmly buttressed in plate spring sheet side, plate spring sheet i.e. laterally centering automatically；Discharging side Formula is changed to the elastic tripper discharging positioned at upper die plate, and during punching, elastic tripper first pushes down plate spring sheet, leaf spring of having decayed Vibrations during punching, improve the comfortableness of employee's operation.

This utility model beneficial effect is that the mould for changing original plate spring sheet punching processing is adjusted and discharge way, significantly The adjustment mould time is shortened, relaxing for employee's operation is improve while production efficiency and punching lateral attitude precision is improve Adaptive, further improve production efficiency.
