The specific embodiment
Below in conjunction with accompanying drawing the structural principle of pin mould of the present invention and the method for using this mould to prepare the pin cold-heading are described in further detail.
Referring to Fig. 1,2, pin cold upsetting forming die of the present invention comprises that one grasps the manipulator 6 that part is used, be provided with the fixing die case 1 of die 2 and cushion block 3 in a side of manipulator 6, die 2 and cushion block 3 are successively set in the die case 1, die 2 is to be used for the cavity that part obtains shaping, center at die 2 and cushion block 3 offers coaxial through hole respectively, push rod 5 is arranged in the through hole of die 2 and cushion block 3, die 2, cushion block 3 and push rod 5 are encapsulated in the die case 1 by being equipped with jack panel 4, opposite side in the front end robot 6 of die case 1 is provided with a convex mould base 8, in convex mould base 8, be provided with punch 7, push rod 5 can be adjusted its relative position at die 2 through hole die cavitys and cooperate with punch 7 adjustment, reach the purpose of part shaping, also play the discharging effect of part simultaneously, punch 7 can be adjusted its relative position in punching stroke makes the part of drift reach technological requirement, also a positioning rod 9 can be set in the punch 7, in the punch 7 of the rear end of backstay 9, also be provided with a spring 10.
Forming method of the present invention is undertaken by following step:
Referring to Fig. 3, blanking: the pay-off by equipment is sent into raw material to cut off in the mould and by the relative shear of 12 in the cutting knife 11, the cutter tube that cut off mould raw material is processed into the material section that needs, locator 13 restriction material segment length and uniformity;
Referring to Fig. 4, integer: because blanking is to shear to finish, therefore on the front/rear end of material section, leave horseshoe-shaped convex-concave vestige, the system of must after shaping, just upsetting, otherwise both ends of the surface can leave indenture behind the forming parts.This station is delivered to the section of expecting between convex mould base 8 and the die case 1 by manipulator 6, moving handle material section by punch 7 pushes in the die cavity of through hole at die 2 centers and pushes, make material section under the effect of protruding, die, form the 1# part that front end face has the burnishing surface of fillet, by push rod 5 the 1# part is headed in the manipulator 6 again, deliver to next station, the effect of fillet is the head preform preparatory condition for next step, is convenient to be shaped;
Referring to Fig. 5, head preform: little according to part two diameter, big these characteristics of interlude diameter, 1# part after head is shaped in advance, again based on the head of moulding in advance, shaping afterbody and shoulder, just can make forming parts is satisfactory part, therefore selected this station is the head preform, and the head materials of reservation can be done suitable adjustment according to the size of formation of parts.This station is delivered to the 1# part between convex mould base 8 and the die case 1 by manipulator 6, the 1# part of motion by punch 7 after with integer pushes and carries out extrusion molding in the die cavity of through hole at die 2 centers and obtain the 2# part, by push rod 5 the 2# part is headed in the manipulator 6 again, deliver to next station;
Referring to Fig. 6, the afterbody preform: the effect of this station is in order to guarantee the back part concentricity of portion end to end that is shaped, the localization part that in die cavity afterbody is shaped pushes out in advance, because this station part is in the die cavity outside in extrusion process middle part sub-material section, so in adjustment, can not make the 2# part at die cavity place produce distortion, make the tail end face size as far as possible near the formation of parts dimensional requirement.This station will be delivered between convex mould base 8 and the die case 1 after will sending into before this station in manipulator 6 transmittance process Rotate 180 ° through the 2# part behind the head preform, the back part concentricity of portion has end to end guaranteed to be shaped, push in the die cavity of the through hole by behind the location of spring 10 in the punch 7 and backstay 9 the 2# part behind the head preform being sent into die 2 centers and form the 3# part, by push rod 5 the 3# part is headed in the manipulator 6 again, deliver to next station;
Referring to Fig. 7, the waist jumping-up: the effect of this station is that the tail end face size reaches the formation of parts requirement part waist jumping-up, and makes tail end face smooth.Principle is according to the calculating of part deformation amount and experiment, prove part in forming process through a waist jumping-up, help part forming, make that deflection reduces behind the part forming.This station will be delivered between convex mould base 8 and the die case 1 by manipulator 6 through the preformed 3# part of afterbody, push in the die cavity of the through hole by behind the location of spring 10 in the punch 7 and backstay 9 the 3# part behind the head preform being sent into die 2 centers and form the 4# part, make the tail end face size reach the formation of parts requirement, and make tail end face smooth, by push rod 5 the 4# part is headed in the manipulator 6 again, deliver to next station;
Referring to Fig. 8, shaping: the effect of this station is to make the each several part size of part reach technological requirement, and principle is to utilize the location of part end to end of preformation, adjusts head and afterbody and length dimension, guarantees the dimensional tolerance of other part of shaping.Utilize the location of part end to end of preformation, by manipulator 6 the 4# part is delivered between convex mould base 8 and the die case 1, form the 5# part by expecting behind the location of spring 10 in the punch 7 and backstay 9 to push in section die cavity of the through hole of sending into die 2 centers, by adjusting head and afterbody and length dimension, guarantee the dimensional tolerance of formation of parts.
The present invention compared with prior art, it is low to have price, the characteristics that the technological process of production is short, Adopt the integer station to solve the irregular defective of end face of the prior art in the part processing.
