The invention discloses a kind of bending push rod moulding process.Including blanking：It is circular rod-like structure that workpiece, which is punched into both ends, obtains push rod；Solid solution：Push rod is put into heating room and is heated to 800 DEG C, discharges stress；Bending；Push rod is placed in the lower die fixed block for being bent into pattern, by the right piece of support of holding pad and molding lower die below push rod, forming punching head pushes, forming punching head protruding portion pushes push rod, it drives holding pad to press at lower bolster to stop, the pusher section of gap forms push rod bending part between left piece and right piece of lower die of molding, and holding pad provides support force for push rod bending part, and push rod bending punching press is completed；Surface chamfer：Chamfering is carried out to push rod bending part both ends；Punching：Push rod both ends circle position is punched out；Hole chamfering：Device to hole carries out Hole chamfering, obtains bending push rod after the completion.The present invention accurately controls the depth of bending part so that push rod compact dimensions are relatively stable, improve product quality.
Description
Technical field：
The invention belongs to turbocharger push rod production technical field, more particularly to a kind of bending push rod moulding process.
Background technology：
Existing push rod is when carrying out pressing and bending, since bending part can cause workpiece bending without support force below workpiece
Depth is unable to control so that punch forming is unstable, affects the quality of push rod.In addition, the stress in workpiece, also be easy to cause
Workpiece bending depth is unable to control after punching press.
Being disclosed in the information of the background technology part, it is only intended to increase understanding of the overall background of the invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or imply that the information is constituted in any form.
Invention content：
The purpose of the present invention is to provide a kind of bending push rod moulding process, above-mentioned in the prior art scarce to overcome
It falls into.
To achieve the above object, the present invention provides a kind of bending push rod moulding process, step is：
(1) blanking：It is circular rod-like structure that workpiece, which is punched into both ends, obtains push rod；
(2) it is dissolved：Push rod is put into heating room and is heated to 800 DEG C, discharges stress；
(3) bending；Push rod is placed in the lower die fixed block for being bent into pattern, by holding pad and molding lower die below push rod
Right piece of support, forming punching head push, and forming punching head protruding portion pushes push rod, drive holding pad to press at lower bolster and stop,
The pusher section of gap forms push rod bending part between left piece and right piece of lower die of molding, and holding pad provides support for push rod bending part
Power, push rod bending punching press are completed；
(4) surface chamfer：Chamfering is carried out to push rod bending part both ends in step (3)；
(5) punching：Push rod both ends circle position is punched out；
(6) Hole chamfering：Hole chamfering is carried out to the hole in step (5), obtains bending push rod after the completion.
Compared with prior art, the present invention has the advantages that：
Bending push rod moulding process can provide support force in push rod punching press for bending part, by solid solution release push rod
Stress, more accurately control the depth of bending part so that push rod compact dimensions are relatively stable, improve product quality.
Description of the drawings：
Fig. 1 is bending push rod moulding process flow process figure of the present invention；
Fig. 2 is bending push rod moulding process bent mold structure schematic diagram of the present invention；
Reference numeral is：1- upper die holders, 2- upper padding plates, 3- forming punching heads, 4- lower pallets, 5- bottom seat pads, 6- lower die holders, 7-
Lower bolster, 8- moldings lower die, 9- holding pads, 10- locating pieces, 11- push rods.
Specific implementation mode：
The specific implementation mode of the present invention is described in detail below, it is to be understood that protection scope of the present invention is not
It is restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other component parts.
As shown in Figs. 1-2, a kind of bending push rod moulding process, step are：
(1) blanking：It is circular rod-like structure that workpiece, which is punched into both ends, obtains push rod；
(2) it is dissolved：Push rod is put into heating room and is heated to 800 DEG C, discharges stress；
(3) bending；Push rod is placed in the lower die fixed block for being bent into pattern, by holding pad and molding lower die below push rod
Right piece of support, forming punching head push, and forming punching head protruding portion pushes push rod, drive holding pad to press at lower bolster and stop,
The pusher section of gap forms push rod bending part between left piece and right piece of lower die of molding, and holding pad provides support for push rod bending part
Power, push rod bending punching press are completed；
(4) surface chamfer：To in step (3) push rod bending part both ends carry out chamfering, both ends chamfer radius be respectively 58mm,
10mm；
(5) punching：Push rod both ends circle position is punched out, bore dia 8mm；
(6) Hole chamfering：Hole chamfering is carried out to the hole in step (5), a diameter of 14mm of chamfering obtains bending and pushes away after the completion
Bar.
As shown in Fig. 2, being bent into pattern and including：Upper die holder 1, upper padding plate 2, forming punching head 3, lower pallet 4, bottom seat pad 5, under
Die holder 6, lower bolster 7, molding lower die 8, holding pad 9, locating piece 10；The upper padding plate 2 is arranged on upper die holder 1, the molding
Punch 3 is arranged on upper padding plate 2, and the forming punching head 3 is fixed on by bolt or screw on upper padding plate 2,6 bottom of the lower die holder
Portion is provided with bottom seat pad 5, and the setting of the bottom seat pad 5 is provided with lower bolster 5, the underlay on lower pallet 4, the lower die holder 6
