Abstract
The utility model relates to a local molding cold heading mould for a bolt, belongs to the field of bolt molding devices and in particular relates to a mould for molding a local part of a bolt. The mould is characterized by comprising a stamping tool shell, an ejector rob (2) and a hard alloy layer (6), wherein the hard alloy layer (6) is arranged in one end of the stamping tool shell in an embedding way; the stamping tool shell is internally provided with a cavity coincided with the bottom of the bolt; the hard alloy layer (6) is internally provided with a ladder through hole communicated with an inner cavity; and the ladder through hole is internally provided with the ejector rob (2). The local molding cold heading mould for the bolt has the advantages of being simple in structure, saving material, reducing cost, shortening the production cycle, lightening the labor intensity and the like.
Description
Technical field
The locally-shaped cold-heading mould of a kind of bolt belongs to bolt former field, is specifically related to the locally-shaped mould of a kind of bolt.
Background technology
At present, the technology of processing high-strength bolt need adopt the major diameter material mostly, and diameter is that the material of φ 15.7 passes through cut then; Being molded into diameter is φ 14.8 and φ 13.3, and in this process, the 2.4mm material of having an appointment is cut; Cause a large amount of wastes and the lower utilization rate of material of material, and per tour class produces and to have only about 350, the process-cycle is longer; Labour intensity is bigger, can not satisfy requirement of mass production.
Summary of the invention
The technical problem that the utility model will solve is: overcome the deficiency of prior art, a kind of economical with materials, stock utilization height, the short locally-shaped cold-heading mould of bolt of process-cycle are provided.
The utility model solves the technical scheme that its technical problem adopted: the locally-shaped cold-heading mould of this a kind of bolt; It is characterized in that: comprise towards tool shell, push rod and hard alloy layer; Hard alloy layer is embedded to be installed in towards tool shell one end inside; Be provided with the cavity that matches with the bolt bottom towards the tool enclosure, hard alloy layer inside is provided with the ladder hole with intracavity inter-connection, and push rod is installed in the ladder hole.
Described towards the tool shell comprise preparatory rammer towards tool shell and moulding towards the tool shell, be steel, upsetting in advance is provided with flange towards tool shell one end, other end lumen port is provided with circular arc.
Described bolt bottom is 5 °～8 ° with upsetting towards the preparatory rammer angle a of tool shell inner cavity in advance, and the length L of upsetting in advance is 9～11mm.
Described bolt bottom and moulding are 25 °～35 ° towards the moulding angle B of tool shell inner cavity.
Described push rod is the setting of T font, and an end withstands on the bolt bottom.
Compared with prior art, the beneficial effect that the utility model had is:
1, chooses the best preparatory rammer angle and the length of upsetting in advance; 2 stations through cooperating cold headers and frock (in advance, mould) are rationally controlled jumping-up, the bar deflection that contracts, to reach progressively distortion, control deformation; Thereby reach the purpose of gathering stock moulding; Reduce staff's labour intensity, shortened the process-cycle, improved efficiency;
2, save material, stock utilization height: through the experiment proof; But the economical with materials consumption has been practiced thrift the lot of materials consumption accordingly up to 18%, has reduced manufacturing cost; And; On this basis, can also guarantee the high-quality and the high quantity of product, satisfy systematization in enormous quantities, needs of scale production, practicality is stronger.
Description of drawings
Fig. 1 is that the utility model installation in preparatory rammer processing step concerns the cutaway view sketch map.
Fig. 2 is that the utility model is installed in the moulding process step and concerned the cutaway view sketch map.
Wherein: 1, upset in advance and mould 5, workpiece 6, hard alloy layer towards tool shell 2, push rod 3, moulding towards tool shell 4.
Fig. 1～2nd, the most preferred embodiment of the utility model further specifies below in conjunction with 1～2 pair of the utility model of accompanying drawing:
The specific embodiment
With reference to accompanying drawing 1:
The locally-shaped cold-heading mould of this bolt; Comprise towards tool shell, push rod 2 and mould 4 and hard alloy layer 6; Hard alloy layer 6 embedded being installed in towards tool shell one end inside; Be provided with the cavity that matches with the bolt bottom towards the tool enclosure, hard alloy layer 6 inside are provided with the ladder hole with intracavity inter-connection, and push rod 2 is installed in the ladder hole.
Towards the tool shell is to upset towards tool shell 1 in advance, is steel, and upsetting in advance is provided with flange towards tool shell 1 one ends; Other end lumen port is provided with circular arc, and the bottom of workpiece 5 bolts is 5 °～8 ° with upsetting towards the preparatory rammer angle a of tool shell 1 inner chamber in advance, and best angle is 6 °; The rammer length L is 9～11mm in advance; Optimum length is 10mm, and push rod 2 is the setting of T font, and an end withstands on workpiece 5 bottoms.
With reference to accompanying drawing 2:
Towards the tool shell be moulding towards tool shell 3, be steel, the bottom of workpiece 5 bolts and moulding are 25 °～35 ° towards the moulding angle B of tool shell 3 inner chambers, push rod 2 is the setting of T font, an end withstands on workpiece 5 bottoms.
The course of work is following:
The utility model cooperates one 2 station cold headers to use in use, and 2 stations through cold headers and frock (in advance, mould) are rationally controlled jumping-up, the bar deflection that contracts, reaching progressively distortion, and control deformation, thus reach the purpose of gathering stock moulding.
At first just upset, through manipulator workpiece 5 is delivered to assigned address, through being fixedly clamped with the middle part of mould 4 with workpiece 5 bolts; Drift moves ahead, and upsets in advance and moves to workpiece 5 towards tool shell 1, and the bottom of workpiece 5 gets in the inner chamber of hard alloy layer 6; Push rod 2 retreats into the dead point of push rod 2, rammer moulding just, and just the rammer shape is similar towards the tool inner chamber with rammer just; Upset force 40000Kgs presses and makes frequency 40 times/minute.
After the rammer moulding just, the drift slide block is up, and the bottom of workpiece 5 gets into moulding in tool shell 3; Moulding continues to move ahead towards tool then; Until with the mould machine, towards the tool dead point, workpiece 5 is whole rammer moulding in moulding rammer drift, whole rammer shape with upset eventually similar towards the tool inner chamber; Upset force 40000Kgs presses and makes frequency 40 times/minute; Workpiece 5 ends can the gathering stock moulding, and clamp body begins to retreat, and push rod 2 begins workpiece 5 is ejected, to be processed 5 ejected fully after and mould 4 open, workpiece 5 free fallings machine.
The above; It only is the preferred embodiment of the utility model; Be not to be the restriction of the utility model being made other form, any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But every the utility model technical scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of the utility model technical scheme according to the technical spirit of the utility model.
