Abstract
The invention relates to a process for forming a helical transmission device and a die for processing the same. The process comprises the following steps of: firstly processing a raw material into circular rings one by one; secondly, cutting out a section of each circular ring in the radial direction, and then pressing the cut circular ring into a helical piece on the die; and finally, welding all the helical pieces into an integrated helical transmission device. The die comprises an upper die and a lower die matched with each other, wherein the upper die is cylindrical and is provided with an inner space corresponding to the inner circle of the circular ring, and the lower end face of the upper die is a die pressing face corresponding to the profile curve of the helical piece; the lower die comprises a positioning column corresponding to the inner circle of the circular ring; a forming column lower than the positioning column is sleeved outside the positioning column; and the upper end face of the forming column is a bearing face corresponding to the profile curve of the helical piece. The invention provides the process for forming the helical transmission device and the die for processing the device, of which the quality of the helical transmission device can be effectively improved without rebound.
Description
Technical field
The present invention relates to a kind of helicoidal gear moulding process and process the mould of this device, belong to the Machining Technology field.
Background technology
Being of wide application of helicoidal gear; Present moulding process all is to adopt earlier sheet shearing to be become the annulus state, and a section is welded together then, after having welded; Adopt electric hoist to pull into spiral helicine transport tape with whole section; This kind technology is prone to cause transmission device not on same horizontal line with the out-of-shape that the helicoidal gear of electric hoist pulling shaping rebounds easily and pulls into, and influences transmission accuracy and influences its service life.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of and does not produce bounce-back, effectively improves the helicoidal gear moulding process of helicoidal gear quality and process the mould of this device.
The technical scheme of the present invention's employing is for this reason: the present invention carries out according to the following steps: earlier raw material is processed into circular one by one; Then along annulus radial shear one section; Then it is pressed into flight on mould, at last with each flight helicoidal gear that is welded into a whole.
The present invention includes the upper die and lower die of working in coordination, said patrix: for cylindric, offer the corresponding inner chamber of circle in the annulus, its lower surface is a mold pressing surface corresponding with the flight contour curve; Said counterdie: comprise with annulus in the corresponding reference column of circle, the outer sheathed shaping column that is lower than reference column of reference column, the shaping column upper surface is a pressure-bearing surface corresponding with the flight contour curve.
Advantage of the present invention is: the present invention changes traditional drawing process manufacturing, adopts the mould compacting, makes the helicoidal gear of producing can not produce bounce-back, and it can remain on same horizontal line, the accuracy of manufacture of raising transmission device, raising transmission accuracy; Other utilizes die production efficient of the present invention high, and its production efficiency of more traditional manufacturing process improves greatly, has reduced the manufacturing cost of product.
Description of drawings
Fig. 1 is the structural representation of mould of the present invention.
1 is that inner chamber, 2 is that mold pressing surface, 3 is that reference column, 4 is that shaping column, 5 is pressure-bearing surface among the figure.
The specific embodiment
Moulding process of the present invention is specific as follows: 1) shear: say that earlier steel plate is cut into disk one by one, and the width of conveyer belt as required cuts the circle in the middle of the disk, be cut into as scheming circularly, annulus is cut off, like figure below again; 2) compacting: the patrix of mould is fixed on above the hydraulic press, and counterdie is fixed on the board of hydraulic press, is placed on before the mould shearing good annulus; Earlier hydraulic press is risen; Then the annulus that shears is put into counterdie, put down patrix again and suppress, the flight one-shot forming is good; 3) welding:, form screw transmission strap with a section weld of the flight that suppresses.
Mould concrete structure of the present invention is following: comprise the upper die and lower die of working in coordination, said patrix: for cylindric, offer the corresponding inner chamber 1 of circle in the annulus, its lower surface is a mold pressing surface 2 corresponding with the flight contour curve; Said counterdie: comprise with annulus in the corresponding reference column 3 of circle, the reference column 3 outer sheathed shaping columns 4 that are lower than reference column 3, shaping column 4 upper surfaces are a pressure-bearing surface 5 corresponding with the flight contour curve.
During mold work: earlier annulus is placed on the reference column 4, patrix is descending then, through the cooperation of mold pressing surface 2 and pressure-bearing surface 5, with flight compression moulding.
Claims (2)
1. helicoidal gear moulding process; It is characterized in that, carry out according to the following steps: elder generation is processed into raw material circular one by one, then along annulus radial shear one section; Then it is pressed into flight on mould, at last with each flight helicoidal gear that is welded into a whole.
One kind processing helicoidal gear as claimed in claim 1 mould; It is characterized in that, comprise the upper die and lower die of working in coordination, said patrix: for cylindric; Offer the corresponding inner chamber of circle in the annulus, its lower surface is a mold pressing surface corresponding with the flight contour curve; Said counterdie: comprise with annulus in the corresponding reference column of circle, the outer sheathed shaping column that is lower than reference column of reference column, the shaping column upper surface is a pressure-bearing surface corresponding with the flight contour curve.
