Abstract
The utility model relates to a hand-operated shape steel cutter which is different from the existing hand-operated machines such as lever shears, gear cutters, etc. The multiple force driving device of the hand-operated shape steel cutter is tightly composed of levers, gears, cam wheels and end teeth. The hand-operated shape steel cutter whose cutting-off diameter (by round steel) is from phi 10 mm to phi 25 mm is small in size, light in weight which is only 12 kg, small applying force and large multiple force. The cutter can be changed to cut off angle steel, etc., according to the shapes of shape steels needed to be cut off. The cutter of the utility model is fixed by press platens with convenient assembly and disassembly. Since the cutter body has no connecting holes, the utility model, therefore, has good intensity, less dehiscence when quenching, a plurality of times of refacing, and long service life.
Description
The utility model name is called type hand steel cutting machine.
The utility model belongs to cold working metal section bar cutting machine.
In hand off machinery background technology, there is lever to cut and the lever and gear wheel cutting machine usually.
The purpose of this utility model is to propose a kind of compact conformation, the application of force is little, the reinforcement multiple is big manual shaped steel cutting machine, cuts off 10 millimeters of diameter phi to 25 millimeters of φ and change blade according to the beam steel shape of required cut-out and can cut off angle steel etc.
Fig. 1, Fig. 2, Fig. 3 are three-view diagrams of the present utility model.
Feature of the present utility model forms three grades of energizing driver structures by body 13, operating lever 1, pinion 2, sector gear 3, unidirectional end tooth clutch 4, unidirectional end tooth clutch 5, cam 6, moving knife seat lever 7, moving knife 8 usefulness pressing plates 12 are fixing, and stationary knife 10 usefulness press 11 to fix. Stationary knife 10 is swallow-tail forms, and pressing plate 11 is single swallow-tail forms.
By Fig. 1, Fig. 2, Fig. 3 as can be known operating lever 1 form first order lever boosting mechanism of the present utility model with the pinion 2 of one end.Pinion 2 and sector gear 3 engagements, by with sector gear 3 one and and unidirectional end tooth clutch 4 power transmissions of sector gear 3 no relative motions to the unidirectional end tooth clutch 5 of cam 6 one.Cam 6 and unidirectional end tooth clutch 5 do not have relative motion yet, and be mechanism's duty this moment.Be sector gear 3 by unidirectional end tooth clutch 4 and 5 and cam 6 connect rotation, when the sector gear backhaul, two end tooth clutches are owing to be that unidirectional meeting is thrown off automatically.
By sector gear 3 unidirectional end tooth clutches 4 and 5 and cam 6 form the second level of the present utility model lever boosting mechanism, link on the sector gear 3 in its energizing driver structure have unidirectional end tooth from 4 two be one move simultaneously and the energizing driver structure in cam 6 on link that 5 two of unidirectional end tooth clutches are arranged is that one is moved simultaneously.
The arm contact of the wheel rim of cam 6 and moving knife seat lever 7, the moving knife 8 that the other end of moving knife seat lever 7 is pressed with pressing plate 12 contacts with the shaped steel of being cut 9.This is a third level lever boosting mechanism of the present utility model.
The utility model with at present preferably the lever and gear wheel cutting machine relatively have maximum only 18 millimeters of the φ of diameter that cut off of volume little (weight only for 12kg), the application of force is little, the reinforcement multiple is big advantage, lever and gear wheel cutting machine, and the cut-out diameter of the utility model maximum is 25 millimeters of φ, and the utility model type cutter is fixed with pressing plate.Mounting or dismounting are convenient, thus because cutter hub is useless good with the hole intensity that connects, not easy to crack during the scold fire, reface often, the life-span is long.
The utility model embodiment is still with description of drawings, in Fig. 1, Fig. 2, Fig. 3, three-view diagram operating lever 1 and pinion 2 make two promptly with steel pipe socket on pinion 2 handles, the time spent can not pull down, and is convenient to preserve.
The ratio of the sector gear 3 and pinion 2 numbers of teeth is 5:1.
The reinforcement multiple of present embodiment is got n
1=40:1, n
2=15:1, n
3=4:1.
The curve of cam 6 can adopt off-centre operation, involute, logatithmic spiral, Archimedes spiral all can, present embodiment adopts Archimedes spiral.
