Abstract

The utility model discloses a bevel wheel heading die. The bevel wheel heading die is composed of an upper die and a lower die, and is characterized in that the upper die comprises an upper die sleeve and a puncher pin, wherein the puncher pin is arranged in an inner hole of the upper die sleeve in a manner of moving up and down; the lower die comprises a lower die sleeve and a rotary die body; the rotary die body is rotatably arranged in an inner cavity of the lower die sleeve by upper and lower plane bearings; an inner hole is formed in the middle of the rotary die body and is used for fixing an alloy die core; the alloy die core is provided with a bevel wheel heading die cavity; the upper section of the die cavity is provided with a straight hole; the lower section of the die cavity is provided with a bevel wheel cavity of which the shape is the same as that of a headed bevel wheel; the bottom of the die cavity is communicated with a rear through ejection rod guide hole; the rear through ejection rod guide hole is internally and movably provided with a rear through ejection rod; when the bevel wheel is coldly headed and molded, the bottom face of the upper die sleeve is clung to the top face of the alloy die core; the head of the puncher pin stretches into the die cavity of the alloy die core. According to the bevel wheel heading die, cold heading and contour machining of the bevel wheel on cold heading equipment can be realized, so that the machining efficiency of the bevel wheel is improved greatly, the machining period of the bevel wheel is shortened and the production cost of the bevel wheel is reduced.

Description

Helical gear upsetting molding jig
Technical field
The utility model relates to a kind of cold upsetting die of car, is specifically related to a kind of helical gear upsetting molding jig.
Background technology
In at present a lot of industry, particularly automobile industries, be applied to the helical gear of small dimension much more especially, current helical gear preparation method is nothing more than machined or die cast processing, at the bottom of helical gear working (machining) efficiency, the helical gear process-cycle is long, and helical gear manufacturing cost is high.
Summary of the invention
The deficiency existing for prior art, the purpose of this utility model is intended to provide a kind of can realize the helical gear upsetting molding jig that helical gear carries out cold-heading molding processing on cold-heading equipment.
The utility model is implemented by the following technical programs:
Helical gear upsetting molding jig, is comprised of upper die and lower die, it is characterized in that: described patrix comprises Upper Die-sleeve and drift, and drift is in the up and down setting of endoporus of Upper Die-sleeve; Described counterdie comprises lower die-sleeve and rotation die body, rotation die body rotatably arranges at lower die-sleeve inner chamber by upper and lower plane bearing, rotation is provided with endoporus in the middle of die body for fixing alloy core rod, alloy core rod is provided with helical gear upsetting molding chamber, die cavity epimere is straight hole, die cavity hypomere has the helical teeth chamber identical with institute upsetting helical gear profile processed, and die cavity bottom communicates with rear logical push rod guide hole, in rear logical push rod guide hole, is movably equipped with rear logical push rod; During helical gear cold-heading molding, the end face of the bottom surface of Upper Die-sleeve and alloy core rod is adjacent to, and the head of drift extend in the die cavity of alloy core rod.
The helical gear upsetting molding jig of technique scheme, can realize helical gear and on cold-heading equipment, directly carry out cold-heading molding processing, operation principle is: first the metal wire rod of cutting into chunks is sent to the die cavity epimere of alloy core rod, then patrix moves down the bottom surface of Upper Die-sleeve and the end face of alloy core rod is adjacent to, then the head of drift extend into the interior pushing downwards of the die cavity metal wire rod of alloy core rod, metal wire rod is pressed against die cavity hypomere subsequently, because die cavity hypomere is helical teeth chamber, so promoting metal wire rod at drift clamp-ons in the process in helical teeth chamber, rotating mould is known from experience the corresponding rotation of generation, until metal wire rod is fully shaped to helical gear, then, drift and Upper Die-sleeve return, the die cavity that rear logical push rod stretches into alloy core rod up ejects workpiece, now rotates die body and also can rotate accordingly, and workpiece is successfully exited from helical teeth chamber, finally completes helical gear cold-heading molding and makes.Because the utility model has been realized the cold-heading molding processing of helical gear on cold-heading equipment, so greatly improved helical gear working (machining) efficiency, shortened the helical gear process-cycle, reduced helical gear manufacturing cost, compared with prior art, there is substantive distinguishing features and progress.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the helical gear outline drawing of the utility model upsetting system.
The specific embodiment
As shown in Figure 1, helical gear upsetting molding jig of the present utility model, is comprised of upper die and lower die, and described patrix comprises Upper Die-sleeve 2 and drift 3, and drift 3 is in the up and down setting of endoporus of Upper Die-sleeve 2, and the top of drift 3 is provided with compression bar 1, described counterdie comprises lower die-sleeve and rotation die body 7, lower die-sleeve is spun and is formed by upper bush 6 and lower sleeve 10 screw threads, rotation die body 7 rotatably arranges at lower die-sleeve inner chamber by upper plane bearing 5 and lower plane bearing 8, prop up on the interior hole end surface of upper bush 6 upper surface of upper plane bearing 5, prop up on pad mould 9 lower surface of lower plane bearing 8, pad mould 9 carries out when screw thread screws being fixed in Upper Die-sleeve at upper and lower sleeve, in the middle of described rotation die body 7, be provided with endoporus for fixing alloy core rod 4, alloy core rod 4 is provided with helical gear upsetting molding chamber, die cavity epimere is straight hole 11, die cavity hypomere has the helical teeth chamber 12 identical with institute upsetting helical gear profile processed, die cavity bottom communicates with rear logical push rod guide hole, in rear logical push rod guide hole, be movably equipped with rear logical push rod 13, during helical gear cold-heading molding, the end face of the bottom surface of Upper Die-sleeve 2 and alloy core rod 4 is adjacent to, and the head of drift 3 extend in the die cavity of alloy core rod 4.
Figure 2 shows that the helical gear outline drawing by the utility model cold-heading molding.The utility model is to realize like this cold-heading molding of helical gear on cold-heading equipment: first the metal wire rod of cutting into chunks is sent to the die cavity epimere of alloy core rod 4, then patrix moves down the bottom surface of Upper Die-sleeve 2 and the end face of alloy core rod 4 is adjacent to, then the head of drift 3 extend into the interior pushing downwards of the die cavity metal wire rod of alloy core rod 4, metal wire rod is pressed against die cavity hypomere subsequently, because die cavity hypomere is helical teeth chamber, so promoting metal wire rod at drift clamp-ons in the process in helical teeth chamber, rotation die body 7 can produce corresponding rotation, until metal wire rod is fully shaped to helical gear, then, drift 3 and Upper Die-sleeve 2 returns, the die cavity that rear logical push rod 13 stretches into alloy core rod 4 up ejects workpiece, now rotates die body 7 and also can rotate accordingly, and workpiece is successfully exited from helical teeth chamber, finally completes helical gear cold-heading molding and makes.
