Abstract
The utility model relates to a bending forming device of a bending pipe of a refrigerator. The bending forming device of the bending pipe of the refrigerator comprises a clamping block, a clamping seat, a handle, a screw rod, a bending spanner, a shaft, a bending wheel group, a base seat, a shaft sleeve, a lower wheel plate and an upper wheel plate, wherein the clamping block and the clamping seat are fixed on the base seat through screws, the screw rod is located in the middle of the top end of the clamping seat, penetrates the clamping seat and is connected with the clamping block, one end of the handle is fixedly connected with the screw rod, and the other end of the handle is a free end. The bending spanner is located at the upper portion of the upper wheel plate, the bending wheel group is located between the upper wheel plate and the lower wheel plate, the bending wheel group, the lower wheel plate and the upper wheel plate are all installed on the shaft sleeve in a sleeve mode, and the shaft penetrates the shaft sleeve and is fixed on the base seat 8 through nut. According to the bending pipe machined through the bending forming device, the outer circle is not concaved and scrapped, the inner circle is not wrinkled, and roundness correction can be carried on a bending part of the bending pipe, so that the roundness requirement of the bending part of a product is guaranteed.
Description
Technical field
The utility model belongs to household appliance technical field, particularly a kind of bend molding apparatus of refrigerator bend pipe.
Background technology
Refrigerator is the household electrical appliances commonly used during people live, on every refrigerator condenser is arranged, condenser nearly all is to adopt very thin aluminum tube bending to form now, because this bend pipe is long, so be easy to that inner ring at crooked position produces wrinkle Zhe and the outer ring cannot not subside roundly during bending machining.
The utility model content
For overcoming defects, the technical problems to be solved in the utility model provides a kind of bend molding apparatus of refrigerator bend pipe, and the bending quality that adopts this device to process is good and can not produce wrinkle Zhe and collapse phenomenon.
A kind of bend molding apparatus of refrigerator bend pipe, this bend molding apparatus comprises: clamp, clamping seats, handle, screw rod, crooked spanner, axle, crooked wheels, base, axle sleeve, lower wheel disc, upper wheel disc; Clamp and clamping seats are fixed by screws on the base; Screw rod is positioned at the top middle portion of clamping seats and passes clamping seats and is connected with clamp; One end and the screw rod of handle are fastenedly connected, and the other end is free end; Crooked spanner is positioned at the top of wheel disc; Crooked wheels are between upper wheel disc and lower wheel disc, and crooked wheels, lower wheel disc and upper wheel disc all are sleeved on the axle sleeve; Axle passes axle sleeve and is fixed on the base 8 by nut.
The bend pipe that adopts reality to process with new device, cylindrical can not produce and subside and scratches, and inner circle can not produce wrinkle Zhe, and can carry out to the crooked position of bend pipe external form school circle, the circularity requirement of assurance product crooked position.
Description of drawings
Fig. 1 is the front view of the utility model bend molding apparatus;
Fig. 2 is the top view of the utility model bend molding apparatus.
The specific embodiment
In the production process of refrigerator bend pipe, the bending machining of bend pipe is the thing of headache.Adding man-hour, if back-up block is crossed pine or mandrel is too small, because aluminum pipe is softer, bending radius is less (only R17) and tube wall again thin (only be 0.75mm), be easy to produce the Zhe that wrinkles at inner ring; If back-up block tension or mandrel are excessive, the rear portion has again very large frictional resistance when crooked, can produce in the outer ring and subside.
Because aluminum pipe hardness is low, material is soft, once tried back-up block and mandrel and adopt the metal materials such as guiding principle, copper to make, but since its hardness greater than aluminum pipe, scratch therefore when producing, can produce on the inside and outside surface of aluminum pipe; Change into than aluminum pipe hardness and hang down the plastic production of a bit, though can not produce scuffing to aluminum pipe, not wear-resisting, only processing 100～200 bend pipes just needs again replacing debugging.
As shown in Figure 1 and Figure 2, the utility model provides a kind of Novel bending shaped device, and this device comprises: clamp 1, clamping seats 2, handle 3, screw rod 4, crooked spanner 5, axle 6, crooked wheels 7, base 8, axle sleeve 9, lower wheel disc 10, upper wheel disc 11.Clamp 1 and clamping seats 2 are fixed by screws on the base 8.Screw rod 4 is positioned at the top middle portion of clamping seats 2 and passes clamping seats 2 and is connected with clamp 1; One end and the screw rod 4 of handle 3 are fastenedly connected, and the other end is free end; Crooked spanner 5 is positioned at the top of wheel disc 11; Crooked wheels 7 all are sleeved on the axle sleeve 9 between upper wheel disc 11 and lower wheel disc 10; Axle 6 passes axle sleeve 9 and is fixed on the base 8 by nut.
When the utility model carries out bending with aluminum pipe, aluminum pipe is passed clamp 1 clamp tubing with 2 one of clamping seats, pull crank handle 5, allow crooked wheels 7 around the moulding of axis of rotation rotoflector.
Adopt the utility model bend molding apparatus, crooked wheels 7 roll along the bending pipes axis, rather than slide, and the pulling force of generation is less, can not cause the crooked position outer ring to subside and produce scuffing; Simultaneously, the circular cross-section between 2 rollers packs tightly tubing, makes its inner ring can not produce wrinkle, and to external form school, bending pipes position circle, guarantees the circularity requirement of product crooked position.
