Detailed description of the invention
For the ease of understanding the purpose of this utility model, technical scheme and effect thereof, now will be elaborated further the utility model in conjunction with the embodiments.
This gives a kind of site operation man-made further destroy steel bar straightening device, as depicted in figs. 1 and 2, comprise two shapes and the substantially similar chopping block 2 of structure, and lead screw 3 arranged in parallel and guide rail pole 1.Guide rail pole 1 can have three, and the diameter of three guide rail poles 1 can be identical with material, is such as ganoid rigidity round bar.Lead screw 3 has one, is distributed between three guide rail poles 1.Adapt with it, as shown in Figure 5, chopping block 2 offers the hole running through chopping block 2, this some holes comprises the screwed hole 2-3 for being socketed lead screw 3, for being socketed the guide rail hole 2-4 of three guide rail poles 1.
Lead screw 3 is rotatable structures in described steel bar straightening device, as shown in Figure 3, the upper and lower of lead screw 3 has the contrary screw thread in direction, two chopping blocks 2 are separately positioned on screw thread place, top and the lower thread place of lead screw 3, lead screw 3 is rotated under the effect of external force, and the rotation of lead screw 3 can drive two pieces of chopping blocks 2 to move in the opposite direction along guide rail pole 1.
According to the screw thread distribution in lead screw 3, lead screw 3 can be divided into successively threaded area, top 3-1, smooth areas, middle part 3-2 and lower thread district 3-3 tri-parts.Wherein, smooth areas, middle part 3-2 does not offer screw thread.The screw thread of threaded area, top 3-1 is contrary with the hand of spiral of lower thread district 3-3.As a preferred embodiment, the screw thread of threaded area, the top 3-1 of lead screw 3 is clockwise thread, and the screw thread of lower thread district 3-3 is anti-clockwise thread.According to the distributing position of two pieces of chopping blocks 2 in lead screw 3, the chopping block 2 being socketed in threaded area, top 3-1 can be called the first chopping block 2-1, the chopping block 2 being socketed in lower thread district 3-3 is the second chopping block 2-2.As mentioned above, the middle part of the first chopping block 2-1 offers the screwed hole 2-3 matched with the screw thread of threaded area, top 3-1, the middle part of the second chopping block 2-2 offers the screwed hole 2-3 matched with the screw thread of lower thread district 3-3, screwed hole 2-3 is in the middle part of three identical guide rail hole 2-4, three identical guide rail hole 2-4 shape arrangements triangular in shape.
The rotation of lead screw 3 needs outer active force, can be workmen's manual rotation lead screw 3, also can be that the equipment such as motor drive rotary screw bar 3.As shown in Figure 3, if rotary screw bar 3 manually, at the end opens two of lead screw 3 for inserting the handle hole 3-4 of handle 6, two handle hole 3-4 vertically offer mutually along the section direction of lead screw 3.At needs straightening reinforcing bar 5, during rotary screw bar 3, handle 6 is inserted one of them handle hole 3-4, manually move handle 6 thus drive lead screw 3 to rotate.In order to save manpower, rotary screw bar 3 can be driven with equipment such as motor.In this case, can connect at the welding edges of lead screw 3 or socket a gear 3-5 that lead screw 3 can be driven to rotate, gear 3-5 the active force that the equipment such as motor replacement handle 6 provides rotary screw bar 3.Certainly, two can also be arranged in the end of lead screw 3 for inserting the handle hole 3-4 of handle 6 simultaneously, and a gear 3-5 that lead screw 3 can be driven to rotate, according to concrete construction environment, carry out different selections.
Two pieces of chopping blocks 2 respectively arrange a binding groove 4, and the effect of binding groove 4 is the ends connecting or import moment reinforcement 5, and in straightening process, fastening reinforcing bar 5 also prevents the slippage of reinforcing bar 5.Specifically, the binding groove 4 of described first chopping block 2-1 is arranged on the upper surface of the first chopping block 2-1, and the binding groove 4 of the second chopping block 2-2 is arranged on the lower surface of the second chopping block 2-2.As shown in Figure 4 and Figure 5, binding groove 4 is made up of reinforcing bar fastening port 4-1 and four fastening latch 4-2 of truncated cone-shaped.Fastening latch 4-2 is successively set on around reinforcing bar fastening port 4-1 upper surface, and the opening diameter that fastening latch 4-2 upper end surrounds is greater than the opening diameter that fastening latch 4-2 lower end surrounds.The opening being in the reinforcing bar fastening port 4-1 of the first chopping block 2-1 upper surface extends to the lower surface of the first chopping block 2-1, the opening being in the reinforcing bar fastening port 4-1 of the second chopping block 2-2 lower surface extends to the upper surface of the second chopping block 2-2, namely two chopping blocks 2 offers through hole matched with reinforcing bar fastening port 4-1.
It should be noted that, in order to improve the stability of described site operation man-made further destroy steel bar straightening device when straightening moment reinforcement, the second chopping block 2-2 also offering one for inserting the handle hole 3-4 of handle 6.As shown in Figure 4, this handle hole 3-4 can offer along the section of the second chopping block 2-2.
As shown in Figure 1, under usual state, the reinforcing bar 5 that site operation man-made further destroy steel bar straightening device is placed is in case of bending, accordingly, upper handle 6 in lead screw 3 is in non-mobile status, and the fastening force that the binding groove 4 of fastening reinforcing bar provides can only ensure that reinforcing bar 5 does not produce dynamic friction.Under this state, machine straightening device described in the present embodiment can be used.
As shown in Figure 2, when the handle 6 on insertion first chopping block 2-1 moves certain angle α (also may be 360 ° of+α) and the handle 6 ensureing on the second chopping block 2-2 does not move, lead screw 3 is based on the reverse screw structure characteristic of himself, drive upper and lower two chopping blocks 2 respectively to upper, move down, the fastening reinforcing bar 5 of fastening force that the movement of two chopping blocks 2 makes binding groove 4 disposed thereon provide larger, and make reinforcing bar 5 simultaneously stressed along the direction of chopping block 2 upwards downward force, drive reinforcing bar 5 to carry out drawing straightening.
Correspondingly, after reinforcing bar 5 straightening, rotate backward the handle 6 on insertion first chopping block 2-1, and ensure that the handle 6 on the second chopping block 2-2 does not move, lead screw 3 drive upper and lower two chopping blocks 2 respectively under, move upward, binding groove 4 does not reoffer fastening force, fastening latch 4-2 automatic spring, and reinforcing bar 5 to remain unchanged shape based on himself rigidity.
The present embodiment gives a kind of preparation process of site operation man-made further destroy steel bar straightening device, specifically comprises the steps:
Step one, makes the reverse screw in two chopping blocks 2, lead screw 3 respectively by pressure rolling lathe, gets three pieces of thin and thick uniform long-narrow triangular mesh iron plates and is pounded by acute angle portion flat as the fastening latch 4-2 in binding groove 4;
Step 2, getting three RRB400 level diameters is the reinforcing bar of 25, by lathe, light is cutd open as guide rail pole 1 in its surface;
Step 3, is connected respectively in the reserving hole in upper and lower chopping block 2 by lead screw 3 and three guide rail poles 1;
Step 4, is welded to the upper end of lead screw 3 by gear 3-5, ensure welding quality;
Step 5, gets two reinforcing bars and inserts the end of the second chopping block 2-2 and lead screw 3 as handle 6;
Step 6, is positioned over fastening latch 4-2 in the opening of truncated cone-shaped reinforcing bar fastening port 4-1 on chopping block 2 and forms binding groove 4.
The utility model is done above in conjunction with the embodiments and further described, but the utility model is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also make a variety of changes under the prerequisite not departing from the utility model aim.
