Description
Technical field
The present invention relates to a kind of cold extruding and forming device of blank of universal joint sleeve.
Background technology
The cold indirect-extrusion mould of the general employing of existing cold extruding and forming device of blank of universal joint sleeve, as Fig. 4, when making axle sleeve by this extrusion die, the interior external diameter axiality of axle sleeve is difficult to control, and interior external diameter also needs Vehicle Processing, and consumptive material is many, and following process is time-consuming.And the mould adjustment is frequent, the quality instability, and production efficiency is low, and operative employee's labour intensity is big.Existing cold extruding and forming device of blank of universal joint sleeve adopts feeding manually simultaneously, poor safety performance, and efficient is low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cold extruding and forming device of blank of universal joint sleeve, and by the axle sleeve axiality height that this device is made, this device security performance is good simultaneously, the efficient height.
For solving above-mentioned prior art problems, the present invention adopts following scheme: a kind of cold extruding and forming device of blank of universal joint sleeve, comprise lathe, be located at the upper die and lower die on the lathe, described patrix is provided with upper bolster, be provided with die in the described upper bolster, be provided with punch in the described die, described counterdie is provided with die shoe, and described die shoe is provided with the lower punch corresponding with last punch that can insert in the die.
As preferably, the described punch of going up is provided with ejector beam, and the below of described patrix is provided with cylinder.By ejector beam workpiece is ejected, utilize cylinder, workpiece is moved on in the packaging case, do not influence repetitive operation subsequently, form production line the workpiece effect.
As preferably, the stock hoisting mechanism that described lathe is provided with automatic feeding, is connected with automatic feeding.Self-feeding, the efficient height, security performance is good.
As preferably, described pay-off comprises the support plate that is located on the lathe, be located at slideway on the support plate, be located at the support plate rear end vertical propulsion plant, be located at the horizontal propulsion plant of support plate front end.
As preferably, described vertical propulsion plant comprises tooth bar and the tooth bar that connects by travelling gear.
As preferably, described horizontal propulsion plant comprises tooth bar and the tooth bar that connects by travelling gear.
Beneficial effect:
The present invention adopts technique scheme that a kind of cold extruding and forming device of blank of universal joint sleeve is provided, axle sleeve axiality height by this device manufacturing, the axiality of the axle sleeve of existing mold extrusion modling is generally at 0.1～0.15mm, and the axiality of the axle sleeve by this device extrusion modling is generally at 0.05～0.08mm; Adopt automatic feeding, security performance is good; Adopt this unit efficiency height, existing extrusion forming device adopts the manual feeding of operative employee, and class produced about 6000 in average 8 hours, adopts this average 8 hours class in device back to produce and reaches about 13000.

The specific embodiment
As Fig. 1 to Fig. 3, and Fig. 5, a kind of cold extruding and forming device of blank of universal joint sleeve, comprise lathe 1, be located at patrix 2 and counterdie 3 on the lathe 1, described patrix 2 is provided with upper bolster 21, is provided with die 22 in the described upper bolster 21, is provided with punch 23 in the described die 22, described counterdie 3 is provided with die shoe 31, and described die shoe 31 is provided with the lower punch 33 corresponding with last punch 23 that can insert in the die 22.The described punch 23 of going up is provided with ejector beam 24, and the below of described patrix 2 is provided with cylinder 25.The stock hoisting mechanism 5 that described lathe 1 is provided with automatic feeding 4, is connected with automatic feeding 4.Described pay-off 4 comprises the support plate 41 that is located on the lathe 1, be located at slideway 42 on the support plate 41, be located at support plate 41 rear ends vertical propulsion plant 43, be located at the horizontal propulsion plant 44 of support plate 41 front ends.Described vertical propulsion plant 43 comprises tooth bar A and the tooth bar B that connects by travelling gear AB.Described horizontal propulsion plant 44 comprises tooth bar C and the tooth bar D that connects by travelling gear CD.Automatic feeding 4 employing rack and pinion drive mechanisms, its each action is all transmitted by the press ram knee-action, does not promptly need power consumption, consumption gas and synchronous with the forcing press action without any need for electrical equipment control.During practical operation, as Fig. 6 to Fig. 9, before workpiece blank slips into tooth bar D from slideway 42, when press ram moves downward, with tooth bar A to pressing down, driving tooth bar B by travelling gear AB retreats, press ram continues to press down, before promoting tooth bar C and shifting workpiece blank onto tooth bar B by travelling gear CD driving-belt carry-over bar D, tooth bar A is connected with press ram, when slide block moves upward, tooth bar A moves up, drive tooth bar B and move forward, workpiece blank is sent into mould, when when the press ram connection presses down once more, repeating said process, the last workpiece blank of mould that is admitted to is at in-mold molding, press ram drives patrix 2 and moves downward upper bolster 21 during moulding, punch 23, die 22 is together with component shaping behind die shoe 31 and the lower punch 33 cooperation extrusion billets, to after bottom dead center, patrix 2 integral body move upward, during to top dead-centre, the workpiece after the moulding is pushed up down by ejector beam 24, and is moved on in the packaging case by cylinder 25 effects.Forcing press moves back and forth, and pay-off also moves back and forth.
