Abstract
An eccentric sleeve high-speed rotating type bar and tube precision blanking machine comprises a transmission mechanism, a radial blanking mechanism and a bar fixing device. By adopting the design that a main shaft drives an eccentric die fixing plate to rotate with high speed, the eccentric die fixing plate imposes radial and circumferential loading effect on the bars and tubes. The blanking die and the eccentric die fixing plate can be replaced according to demands of different processes. Precision blanking can be achieved according to different materials and bars and tubes of different diameters. The blanking machine is compact in structure, high in efficiency, low in cost, is practical and convenient and the like.
Description
Technical field
The present invention relates to the blanking machine technical field, be specifically related to a kind of eccentric bushing high-speed rotary bars and tubes material precision blanking machine.
Background technology
The blanking of metal bar material extensively is present in the procedure for preparation of cold extrusion, die forging, metal bracelet pin, rolling bearing roller, pin standard component and axle type part; And in these blanking operations; The blanking enormous amount; For example the annual metal bracelet length of producing in the township of the chain in Jinhua, Zhejiang area can reach more than one hundred million rice, and the needle roller that the Beijing Needle Bearing Factory needs every year reaches up to ten million.But in the baiting methods such as at present traditional shearing, sawing, high energy cutting in various degree have problems such as stock utilization is low, blanking pressure is big, production efficiency is low, energy consumption is high, cross section quality difference, do not meet the requirement of green manufacturing.
Traditional baiting method comprises that lathe cuts off and sawing machine is sawed-off, though these two kinds of baiting methods can obtain smooth section, exists production efficiency low, shortcomings such as waste raw material.For this reason; Extensively adopt punch press or special-purpose bar shears to carry out the method for shearing blanking in the commercial production afterwards; But common shearing blanking method blanking pressure is big, energy consumption big, the bar section that descends presents the tangible shape of a hoof; In order to satisfy next procedure such as cold-stamped requirement, the operation of having to behind common shearing blanking, arrange again one smooth section of turning has so just reduced production efficiency, has wasted material, has increased production cost.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of eccentric bushing high-speed rotary bars and tubes material precision blanking machine, can obtain good cross section quality, and have that the range of work is wide, efficient is high, quality is good, energy-saving advantages.
In order to achieve the above object, the present invention takes following technical solution:
A kind of eccentric bushing high-speed rotary bars and tubes material precision blanking machine comprises transmission mechanism and radial loaded cutting agency and bars and tubes material fixture,
Transmission mechanism comprises main motor 1, on the axle of main motor 1 driving pulley 2 is installed, and the main motor 1 following same horizontal plane in frame 4 upper edges disposes power transmission shaft 7 and main shaft 5; Main shaft 5 is hollow; Power transmission shaft 7 one ends are equipped with driven pulley 6, and the other end is equipped with gear 8, and gear 8 connects main shaft 5; One end of main shaft 5 is fixed on the frame 4, and driving-belt 3 connects driving pulley 2 and driven pulley 6;
The radial loaded cutting agency comprises blanking mould 14, and blanking mould 14 is connected on the eccentric mould fixed disk 9 through bearing 11, and eccentric mould fixed disk 9 is fixedly connected on the other end of main shaft 5 through setting circle pin 10;
The bars and tubes material fixture comprises support 16; Support 16 is fixed on the slide block 17; Slide block 17 is configured on the base plate 20; On support 16, be fixed with bars and tubes material fixed cover 12, bars and tubes material positioning sleeve 13 tightly fits in the bars and tubes material fixed cover 12, disposes drawing-inroller 18 and following drawing-inroller 19 in the outside of support 16.In the blanking process, feed mechanism adopts the mode that goes up drawing-inroller 18 and 19 rollings of following drawing-inroller to give, and bar B one end is placed in the blanking mould 14, and an end is placed on 13 li of bars and tubes material positioning sleeves.
Eccentric bushing high-speed rotary bars and tubes material precision blanking machine of the present invention; When carrying out blanking, the bar centering is static, after motor is opened; Along with the rotation of main shaft and then drive eccentric mould fixed disk and rotate; Will circumferentially load a blanking of every completion, feed mechanism feeding and then accomplish next blanking once more like this to bars and tubes material.Reasonably just reach the stable expansion that layout and structural design are impelled micro-crack, guarantee cross section quality.Have the efficient height, energy consumption is low, compact conformation and advantage such as economical and practical.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed description.
With reference to Fig. 1, Fig. 2, a kind of eccentric bushing high-speed rotary bars and tubes material precision blanking machine comprises transmission mechanism and radial loaded cutting agency and bars and tubes material fixture,
Transmission mechanism comprises main motor 1, on the axle of main motor 1 driving pulley 2 is installed, and main motor 1 drives driving pulley 2 and rotates, and the main motor 1 following same horizontal plane in frame 4 upper edges is being placed power transmission shaft 7 and main shaft 5; Main shaft 5 is hollow, and the bars and tubes material of accomplishing blanking drops out through spindle cavity, and power transmission shaft 7 one ends are equipped with driven pulley 6; The other end is equipped with gear 8, and gear 8 is effects of main shaft 5 being played speed change, and gear 8 connects main shaft 5; One end of main shaft 5 is fixed on the frame 4, and another termination is equipped with eccentric mould fixed disk 9, and eccentric mould fixed disk 9 is an eccentric structure; Can carry out circumferentially loading continuously to bars and tubes material, eccentric amount e can be changed according to the different process needs; This structure can play good loading effect to bars and tubes material, and driving-belt 3 connects driving pulley 2 and driven pulley 6, and driving-belt 3 drives driven pulley 6 and power transmission shaft 7 rotates; And play the raising speed effect, and power transmission shaft 7 driven gears 8 rotate main shaft 5, and 8 pairs of main shafts 5 of gear play the effect of raising speed simultaneously;
The radial loaded cutting agency comprises eccentric mould fixed disk 9, setting circle pin 10, bearing 11 and blanking mould 14; Blanking mould 14 is connected on the eccentric mould fixed disk 9 through bearing 11, and eccentric mould fixed disk 9 is connected on the main shaft 5 through screw 15, setting circle pin 10, and rotates with main shaft 5; Main shaft 5 supports through bearing 11; Since the supporting role of bearing 11, blanking mould 14 transfixions, and then bars and tubes material is not rotated with main shaft 5;
