Abstract
The utility model discloses a large-diameter circular steel cold bending device which does not need to be heated up. The large-diameter circular steel cold bending device is realized by the following technical scheme: the device consists of a mould bracket, a plurality of upper mould wheels and a plurality of lower mould wheels, wherein the mould bracket consists of a lower base board, a support board and an upper pull board; the lower mould wheels are movably connected with two ends of the supporting board trough pin shafts; the upper mould wheels are arranged among the lower mould wheels, the peripheral surfaces of the upper mould wheels are provided with grooves, and the upper parts of the upper mould wheels are provided with slots. The large-diameter circular steel cold bending device mainly solves the problem of the bending of the large-diameter circular steel, improves the original technique that the bending can be performed only by heating, is good in molding, and improves the labor productivity.
Description
Technical field
The utility model relates to a kind of major diameter round steel bending apparatus, more particularly, relates to a kind of clod wash device that round steel is bent to given shape.
Background technology
When round steel was crooked, it is crooked that the major diameter round steel need heat the back, along with steel development in the past, to the production duration, technological requirement, the requirement of ferrous materials character is more and more higher, especially stainless steel is processed into circle or S type, and work in-process does not allow heating, and is simultaneously also uneconomical, produce following some deficiency here: one, heating back bending, material behavior changes, and moulding is bad, need sometimes bending part is knocked finishing, be easy to occur pounding very much trace; Its two, during the bending of major diameter round steel, the common thermal flexure that adds is difficult to meet the demands, even common bender is not accomplished yet; Its three, after the heating bending, the docking port place is inconsistent, produces buckling deformation; At last, when producing in batches, it is many to consume manpower and man-hour, and production efficiency is extremely low.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of major diameter round steel clod wash device of heating of not needing is provided.
The utility model major diameter round steel clod wash device, be achieved by following technical scheme: described device is made up of clamping fixture support, last tire wheel and following tire wheel, described clamping fixture support is made up of lower shoe, support plate and last arm-tie, the described wheel of tire down is movably connected in the support plate two ends by bearing pin, the described tire wheel of going up is arranged at down between the tire wheel, last tire wheel side face is provided with groove, and last tire top is provided with fluting.
The utility model has mainly solved major diameter round steel buckling problem, has improved that need to heat could crooked technology in the past, forming, and labor productivity has improved, and working strength of workers has reduced, and crooked radius such as can regulate at advantage.Use the forming of the utility model bending part, outward appearance does not have impression; Can accomplish the bending work that heating bending and common bender can't be finished to the bending of major diameter round steel; The docking port place can be consistent after the moulding; When producing in enormous quantities, both saved human resources, increased substantially production efficiency again.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, device is made up of clamping fixture support, last tire wheel 1 and following tire wheel 2, described clamping fixture support is made up of lower shoe 4, support plate 3 and last arm-tie 5, the described wheel of tire down is movably connected in the support plate two ends by bearing pin 6, the described tire wheel of going up is arranged at down between the tire wheel, last tire wheel side face is provided with groove, and last tire top is provided with fluting 7.
Last tire wheel fluting place connects pressure apparatus, is connected on the pressure apparatus by bearing pin, does not rotate when work, according to producing needs, when rolling over the round steel of other diameters, looks radius bend and uses the corresponding tire wheel of going up.
Clamping fixture support is looked the diameter and the radius after the bending of bending part and is selected suitable support plate, arm-tie, base plate according to producing needs.
Following tire wheel roller cooperates copper sheathing to use (closely cooperate, and wear-resistant), and when work, 2 following tires wheels rotate, and are consistent with last tire wheel, bending part.
With the folding diameter is that the round steel of 32mm is an example, further describe use: mix up length ratio, frame is on following tire wheel 2, and 2 following tires wheels can rotate, last tire is taken turns 1 fluting place and is connect pressure apparatus, go up tire wheel 1 during work and do not rotate, the application of force vertically downward then is stuck in bending part in the groove that tire takes turns, the general groove diameter of tire wheel that goes up is greater than bending round steel 1mm ~ 3mm, guarantee when bending, bending part to be fixed, be pressed into the circular arc state that needs at last.
Claims (2)
1. major diameter round steel clod wash device, it is characterized in that, described device is made up of clamping fixture support, last tire wheel and following tire wheel, described clamping fixture support is made up of lower shoe, support plate and last arm-tie, the described wheel of tire down is movably connected in the support plate two ends by bearing pin, the described tire wheel of going up is arranged at down between the tire wheel, and last tire wheel side face is provided with groove, and last tire top is provided with fluting.
2. major diameter round steel clod wash device according to claim 1 is characterized in that, the described tire wheel side face groove diameter that goes up is greater than round steel diameter 1mm～3mm.
