Abstract

The utility model relates to a rolling machine, comprising a frame and two rolling shafts matched with each other. Two pairs of rolling dies matched with each other are distributed on the rolling shaft; the phases of the rolling dies are different; a plurality of cams matched with the rolling dies are also distributed on the rolling shaft; the phase of the cams is 180 degrees different from the phase of a platform and the rolling dies; the height H1 of the cams outstanding the shaft plane of the rolling shaft, the height H3 of the rolling dies outstanding the shaft plane of the rolling shaft and the free clearance H2 between the shaft plane of the rolling shaft and the platform have the relationship that H1 1is greater than H2 and H2 is greater than H3. The rolling machine can complete two rolling processes of different technological requirements with one machine; equipment investment is saved by 50% compared with the prior art, and occupied area is reduced by 50%.

Description

A kind of roller press

The utility model relates to a kind of roller press.

Roller press is a kind of machinery that thick metal derby is processed into thin metal derby by the mode of roll extrusion.In the daily life, many hardware ﹠ tools all are processed into by multiple tracks roll extrusion program, as cutter, hoe tool etc.The multiple tracks roll extrusion program of processing hardware ﹠ tools has different technological requirements sometimes, needs this moment many roller presses to finish the roll extrusion program of multiple tracks different process requirement.Every roller press all was equipped with power set respectively in the past, and in order to reduce fixed investment, general way was that two roller presses are share a power afterwards, as the small-sized Hardware Tools Factory under the applicant, there are two roller presses in this factory, and one for rolling long roller press, and another is for rolling wide roller press.The master of two roller presses, it is that driving shaft is given driven pulley with transmission of power and share cover power set by gear that driven shaft cooperates by gear, prior art was compared with former technology, two roller presses share cover power set, saved a cover power-equipment, reduced the floor space of one-time investment and machine so to a certain extent, but still there is following shortcoming in this method of having improved: two frames of two roller press needs and two supports, 1.5t frame need 12000-13000 yuan of investments by every of current market price, two frames are then invested 24000-26000 yuan altogether, add two supports and then need 30000-32000 yuan of accumulative investments, not only equipment investment is big, and floor space is wide.

The purpose of this utility model is to provide a kind of roller press, and this roller press one function is finished the roll extrusion program of twice different process requirement, has compared with prior art reduced the fixed investment and the floor space of equipment.

In order to achieve the above object, the technical solution of the utility model is design like this:

Its structure of described roller press is to improve on the basis of existing technology and come, its structure comprises the rolling shaft that frame and two matches, rolling shaft is fixed on the frame, rolling shaft one end is connected with power set, it is characterized in that: be distributed with two pairs of rolling forging dies that match respectively on the described rolling shaft, the phase place of two pairs of rolling forging dies is inequality.Wherein be distributed with cam on a rolling shaft and the corresponding position of a rolling forging die, cam is with 180 ° of corresponding rolling forging die phase phasic differences, and the cam platform matches with cam, the height H of the outstanding axial plane of cam ₁, the outstanding axial plane of corresponding rolling forging die height H ₃, the free clearance H between axial plane and the platform ₂The pass be H ₁＞H ₂＞H ₃

A kind of roller press described in the utility model, two pairs of rolling forging dies have been installed on a pair of rolling shaft, two pairs of rolling forging dies can be distinguished independent acting, and the working clearance of two pairs of rolling forging dies can regulate respectively to a certain extent, can a machine finish the roll extrusion program of twice different process requirement, the function that is actually two roller presses is incorporated on the roller press, compares with prior art, both save equipment investment, reduced floor space again.A kind of roller press described in the utility model, 1.5t frame need 12000-13000 yuan of investments by every of current market price, add each support and then need 15000-16000 yuan of accumulative investments, compare with the roller press of this same production capacity of factory, saved equipment investment 50%, and having reduced by a desktop machine base, floor space has reduced 50%.

Describe the utility model in detail below in conjunction with drawings and Examples.

Fig. 1 is the main cutaway view of embodiment,

Fig. 2 is the left view of Fig. 1,

Embodiment:

According to Fig. 1, Fig. 2, the described a kind of roller press of present embodiment, its structure comprises frame 7, active rolling shaft 4 and passive rolling shaft 10.Two rolling shafts 4,10 are fixed on the frame 7 by bearing shell 5 and axle bed 6 activities, and an end of two rolling shafts 4,10 is connected with gear-box 9.Rolling shaft 4,10 is equipped with a pair of rolling forging die 8,11,180 ° of the phase differences of rolling forging die 8,11 on the axial plane between the frame 7.The axial plane that rolling shaft 4,10 is positioned at frame 7 one sides is equipped with another to rolling forging die 3,12,180 ° of same rolling forging die 3,12 phase phasic differences.Also be equipped with the cam 2 that matches with rolling forging die 12 on the passive rolling shaft 10,180 ° of the phasic differences mutually of cam 2 and rolling forging die 12.The table surface height of platform 1 can be regulated within the specific limits, and cam 2 matches with platform 1.The height H of cam 2 outstanding rolling shaft 10 axial planes ₁, outstanding rolling shaft 10 axial planes of rolling forging die 12 height H ₃, rolling shaft 10 axial planes and platform 1 table top gap H ₂The pass be H ₁＞H ₂＞H ₃

Claims (1)

1. A kind of roller press, one end and power set are connected, its structure comprises frame (7) and two rolling shafts that match (4,10), it is characterized in that: be distributed with two pairs of rolling forging dies that match respectively (8,11) and rolling forging die (3,12) on the rolling shaft (4,10), the phase place of rolling forging die (8,11) and rolling forging die (3,12) is inequality, rolling shaft (10) also is distributed with the cam (2) that matches with rolling forging die (12), cam (2) and platform (1), 180 ° of the phasic differences mutually of cam (2) and rolling forging die (12), the height H of outstanding rolling shaft (10) axial plane of cam (2) ₁, outstanding rolling shaft (10) axial plane of rolling forging die (12) height H ₃, the free clearance H between rolling shaft (10) axial plane and the platform (1) ₂The pass be: H ₁＞H ₂＞H ₃
