Description

Bolt heat pier multistation mould

Technical field

The utility model relates to bolt processing, specifically a kind of bolt heat pier multistation mould.

Background technology

Six square toes portions of bolt are stamped to form by heating, produce bolt technique at present and are: forcing press by the first blanking-chamfering punching-heating pier of mould slightly-portion-machined of punching press six square toes.Pier has slightly been become two procedures with punching press six square head portion by such technique, and cause twice heating, efficiency comparison is low, and electric energy loss is also larger.

Utility model content

The purpose of this utility model is for overcoming the deficiencies in the prior art, and provides a kind of bolt heat pier multistation mould, and this mould structure is simple, and practicality is high.

The technical scheme realizing the utility model object is:

A kind of bolt heat pier multistation mould, by forcing press, is arranged on cope match-plate pattern on forcing press and lower bolster forms, unlike the prior art: be also provided with the thick patrix of pier, the thick counterdie of pier, shaping upper, shaping counterdie, wherein:

The thick patrix of pier, shaping upper are connected with the upper bolster be arranged on cope match-plate pattern, cope match-plate pattern is fixed on the slide block of forcing press, and drive it to move with the motion of slide block, cope match-plate pattern is also provided with the first upper ejector pin, the second upper ejector pin, die shank and knockout rod, second upper ejector pin is movably arranged in upper bolster, and is flexibly connected with the thick patrix of pier, shaping upper; Shaping upper lower end is connected with drift, and the first upper ejector pin is connected with die shank, and knockout rod is horizontally installed between die shank and the second upper ejector pin;

The thick counterdie of pier, shaping counterdie are arranged on the die shoe of lower bolster, and thick patrix, shaping upper are oppositely arranged with pier respectively, in die shoe, be movably equipped with lower push rod, and counterdie thick with pier, shaping counterdie are flexibly connected respectively, are respectively equipped with spring bottom die shoe; Be connected by guide pillar between cope match-plate pattern with lower bolster.

The thick counterdie of described pier and shaping counterdie are respectively equipped with counterdie adapter sleeve.

Described upper bolster and die shoe can respectively by the length in plus/minus cushion block adjusting bolt head and bar portion.

The utility model has the advantages that: pier, thick and punching press six square toes portion carries out the utility model mould simultaneously, namely press ram runs once, can pier, thick and six sides be shaping is disposablely up to, original two procedures is become a procedure, and efficiency significantly improves, and saves power consumption, relatively simple for structure, practicality is higher, and the head of bolt and bar minister degree can at upper bolster and die shoe plus-minus cushion blocks, free adjustment.

Detailed description of the invention

With reference to Fig. 1, the utility model bolt heat pier multistation mould, is made up of die shank 1, first cope match-plate pattern 2, knockout rod 3, second cope match-plate pattern 4, second upper ejector pin 5, upper bolster 6, the thick patrix of pier 7, guide pin bushing 8, guide pillar 9, shaping counterdie 10, counterdie adapter sleeve 11, die shoe 12, lower bolster 13, lower push rod 14, first upper ejector pin 15, the thick counterdie 16 of pier, shaping upper 17, drift 18.The thick patrix 7 of pier, shaping upper 17 be arranged on upper bolster 6, upper bolster 6 is arranged on the second cope match-plate pattern 4, first cope match-plate pattern 2 is fixed on the slide block of forcing press, and drive it to move with the motion of slide block, first upper ejector pin 15 is connected with die shank 1, and being arranged on the first cope match-plate pattern 2, the second upper ejector pin 5 is movably arranged in upper bolster 6, and is flexibly connected with the thick patrix 7 of pier, shaping upper 17; Shaping upper 17 lower end is connected with drift 18, and knockout rod 3 is horizontally installed between die shank 1 and the second cope match-plate pattern 4; And be flexibly connected with the second upper ejector pin 5.

The thick counterdie of pier 16, shaping counterdie 10 are arranged on die shoe 12, and thick patrix 7, shaping upper 17 are oppositely arranged with pier respectively, die shoe 12 is arranged on lower bolster 13, spring is respectively equipped with bottom it, in die shoe 12, be movably equipped with lower push rod 14, counterdie 16 thick with pier, shaping counterdie 10 are flexibly connected respectively; Second cope match-plate pattern 4 is connected by guide pillar 9 with between lower bolster 13, and guide pillar 9 outer wall is provided with guide pin bushing 8.

Counterdie adapter sleeve 11 is respectively equipped with at the thick counterdie of pier 16 and shaping counterdie 10.

Upper bolster 6 and die shoe 12 can respectively by the length in plus/minus cushion block adjusting bolt head and bar portion.

The technical process of the utility model mould is: blanking-chamfering punching-pier slightly shaping-machined.Specifically:

First the bar heated is placed on inside the thick counterdie 16 of pier, press ram moves downward, complete pier unskilled workman sequence, blank after again pier is thick is placed in shaping counterdie 10, the bar just heated is placed in the thick counterdie 16 of pier simultaneously, forcing press moves downward, and can complete the thick and punch forming six square toes portion of pier simultaneously.Cope match-plate pattern is fixed on press ram, the motion of slide block can be moved together with cope match-plate pattern, slide block moves downward, patrix 7 and 17 and then downward extruded bar stock simultaneously makes it distortion, lower push rod 14 is squeezed and moves downward until contact with die shoe 12, complete on punching press rear slider and move, bolt upsprings under spring force below, be ejected and counterdie 16 and 10. slide block moves to a certain degree, the knockout plate that forcing press carries can be beaten push rod 15 downwards, push rod 15 passes to knockout rod 3 this power, two upper ejector pins 5 are below passed to again by knockout rod 3, pass to two drifts 18 below more respectively, bolt head can be got patrix.
