Description
Technical field
The utility model relates to the curved instrument of a kind of tubing system.
Background technology
At present, the aluminium-plastic pipe ectonexine on market is Special polyethylene material, clean nontoxic, level and smooth, more than ISUZU company can be used, and middle aluminium lamination can 100% the infiltration of isolated gas, therefore aluminium-plastic pipe has the advantage of metal tube and plastic pipe simultaneously, is widely used in Heating of High-rise Building system.In aluminium-plastic pipe construction technology, the system of tubing is curved is key in whole operation, often adopt manual system curved, this needs operating personnel repeatedly to adjust, not only efficiency of construction is low, and adjustment number of times too much can cause tubing inner core impaired, once inner core is impaired, must change tubing, the loss therefore caused is very big.
On market, finished product pipe bender acquisition price is higher, and is only suitable for bending 90 degree of right angles, when tubing does local wide-angle adjustment, and inapplicable; In addition, during the operation of finished product pipe bender, the tubing of most short end requires to be greater than 40cm, and the minimum length that the tubing of general right-angle bending requires in engineering is 20cm, therefore, tubing also needs to clip 20cm and just can come into operation after bending through finished product pipe bender, this just causes the waste of material, virtually improves cost.
Utility model content
The purpose of this utility model is to provide a kind of 46 ° of aluminium-plastic pipe pipe bendeies, solve traditional pipe bender bad adaptability, application extensively and the high technical problem of cost; And solve the problem improving efficiency of construction, reduce waste of material, reduce construction cost.
For achieving the above object, the utility model adopts following technical scheme:
A kind of 46 ° of aluminium-plastic pipe pipe bendeies, comprise handle and the corner being connected to handle end, described corner is a short steel pipes, handle one end is welded in angle α in the middle part of it, the scope of angle α is 35 ° ~ 55 °, the upper port of corner is flat mouth, lower port is the groove tilted towards handle orientations, and the tube wall of the lower end of corner and handle homonymy is towards the cambered surface of handle orientations smooth curved transition, groove minimum point extended line straight up scope that is crossing with corner axis, both angle β is 35 ° ~ 55 °.
The length of described handle is 30cm ~ 50cm.
The length of described corner is 5cm ~ 9cm.
Described corner is welded still pipe or coating steel pipe.
Described angle α is 46 °, and angle β is 46 °.
Compared with prior art the utility model has following characteristics and beneficial effect:
The utility model overcomes that old of traditional pipe bender is high, the shortcoming of very flexible, waste material, solves the technical problem improving efficiency of construction, increase the scope of application, reduce costs.
The utility model utilizes lever principle making pipe bender, structure simply, easily operates, and workmen only needs operation can realize the curved object of tubing system for three times, improves the curved efficiency of system; In addition, corner one end is bent to form groove and plays the object controlling bending pipes accuracy, also plays the effect of protection tubing flexure plane simultaneously, avoids causing mechanical damage to tubing skin and avoiding bending pipes to occur the situation generation at dead angle; The utility model is that the welded still pipe that generally used by job site or coating steel pipe etc. make as raw material, and cost is low.
The core of pipe bender controls degree of crook exactly, should be formed effective bending, can not damage tubing again, through the angle to corner and handle, the length of corner and the length of handle repeatedly adjust, the scheme finally determined is to realize best bending pipes effect, farthest ensure that the scope of application of the present utility model, no longer be confined to 90 degree of situations about bending, also reduce the length requirement to tubing simultaneously, waste of material can not be caused, reduce further cost: first, the length of pipe bender flat segments is decided to be about 6 cm by the utility model, and the other end is designed to cambered surface to protect tubing not impaired in the curved process of system, secondly, according to technological requirement, the minimum bending radius of aluminium-plastic pipe is 5D, and wherein D is aluminium-plastic pipe external diameter, bending radius is excessive affects result of use, and it is impaired to bend through little tubing inner core, therefore, bevel angle is set in about 46 °, through three bending adjustment, just can reach bending requirement.
It is curved that the utility model can be widely used in plastic-aluminum control.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structure schematic side view of the present utility model.
Fig. 3 is using state schematic diagram of the present utility model.
Reference numeral: 1-handle, 2-corner, 3-aluminium-plastic pipe.
Detailed description of the invention
Embodiment is shown in Figure 1, this 46 ° of aluminium-plastic pipe pipe bendeies, comprise handle 1 and the corner 2 being connected to handle end, and described handle is the long steel pipe of a 40cm length, and corner 2 is short steel pipes of a 6cm length, described long steel pipe and short steel pipes are as welded still pipe or coating steel pipe.
Shown in Figure 2, the middle part of corner 2 is that angle α is welded on handle one end, angle α is 46 °, the upper port of corner is flat mouth, lower port is the groove tilted towards handle orientations, and the tube wall of the lower end of corner and handle homonymy is formed by hot-working, towards the cambered surface of handle orientations smooth curved transition, bevel angle is 46 °, and the angle β that namely groove minimum point extended line is straight up crossing with corner axis is 46 °.
Shown in Figure 3, for using method of the present utility model: during use, aluminium-plastic pipe 3 is passed from corner 2, exert a force downwards operating grip 1 in the direction of the arrow, aluminium-plastic pipe 3 is stressed becomes curved to dashed lines states in the direction of the arrow, cambered surface on corner will cause damage also to avoid aluminium-plastic pipe to be bent into dead angle to aluminium-plastic pipe as force part simultaneously, and this is the advantage that simple straight tube can not possess.
Funds demand of the present utility model:
1, the expense needed for personnel's research process about 30,000 yuan; 2, R&D process material and testing expenses about 1.5 ten thousand yuan; 3, single finished product pipe bender expense: about 200 yuan, comprise coating steel pipe 0.5 meter, groove hot-working cost and welding polishing cost, construction unit construction area 10,000 square metres of needs pipe bendeies 5 are calculated by experience, as needed 250 by 1,000,000 square metres by 50% outfit, required expense 250 × 200=50000 unit, R rates quoted above adds up to 9.5 ten thousand yuan.
Economic benefit of the present utility model:
For high residential building 150 family, each household radiator quantity is 5 groups, and one group of radiator needs the quantity of bend pipe process to be 2, then total bend pipe process quantity=150 × 5 × 2=1500 place.
1, cost of labor calculates:
If do not use the utility model to carry out bend pipe process need 20 minutes, the bend pipe operating time about one times can be shortened after using, per work day calculates by work for 8 hours, then save work day=1500 × 10min=31.25 work day, 250 yuan/work day of actual water power skilled worker wage, add up to 7812.5 yuan/building, namely every house can save cost of labor 8,000 yuan nearly, says that product qualified rate brings up to 100% simultaneously.
2, finished product pipe bender expense calculates:
Each about 500 yuan of market finished product pipe bender, cost of the present utility model about 200 yuan, namely each pipe bender can be cost-saving 300 yuan.
3, Master Cost calculates:
Owing to using the utility model to pipe length not requirement, tubing after bend pipe, without the need to intercepting 20cm again, treats that so each the tubing of bend pipe process can save material 0.2m, then tubing saving=1500 × 0.2m=300m, tubing cost is 11 yuan/m, then one amounts to saving 3300 yuan.
