Abstract
The invention discloses a technology method for bending a conical heat exchange tube. The method sequentially comprises the following steps that firstly, an original grinding tool R wheel of a universal tube bending machine is heightened by 10 mm, a tube clamping grinding tool is increased by a certain height (10 mm), and a push rod oil seal is decreased to a certain height (5 mm); secondly, a straight tube is placed in the grinding tool, the straight tube is clamped according to the process, and an angle is set. The one-time bending forming processing method for the conical heat exchange tube is provided, one-time forming can be achieved, the efficiency is improved, the machining cost is lowered, and the quality is guaranteed.
Description
Technical field
The present invention relates to oil, chemical machinery, the field of heat exchangers such as medical, a kind of taper heat exchanger tube that relates in particular to heat exchanger once bends the device of moulding.
Background technology
The universal bending machine that bends that at present oil, chemical machinery, the heat exchanger tube such as medical change only can be as bending rectangle, square and single U-shaped pipe, and the general original process method that taper (Pagoda-shaped) pipe bends be bend after the single U-shaped pipe of N section assembly welding tapered (Pagoda-shaped) can not one-shot forming, so, not only increase assembly welding operation (workload) and cost, quality is difficult to again guarantee, and efficiency is lower simultaneously.
Summary of the invention
The object of the invention is exactly can not bend in order to solve universal bending machine the defect that taper heat exchanger tube bends technology, provides taper heat exchanger tube once to bend moulding technique, and it can one-shot forming, has improved efficiency, has reduced processing cost, has guaranteed quality.
The present invention is achieved by the following technical solutions:
The process that taper heat exchanger tube bends, carry out according to the following steps successively:
First, the former grinding tool R wheel of universal bending machine is increased to 10mm height, tube grip grinding tool improves certain altitude 10mm, and push rod oil sealing reduces height 5mm;
Secondly, institute's straight tube is put into grinding tool, by flow process, clamp and arrange angle;
Then, release the button that it is U-shaped curved to start to bend, first measurement size A, clamps back elbow, finds out R center after completing, and size up B, clamp back elbow, after completing, find out R center, and size up C, clamp back elbow, after completing, find out R center, and size up D, and bend down according to this.
The present invention, by by the universal bending machine grinding tool frock of transformation, cancels the operations such as the assembly welding of existing technique and detection, adopts once to bend moulding technical matters taper (Pagoda-shaped) heat exchanger tube is bent to one-shot forming.
Advantage of the present invention is:
1, save cost: as a long pipe of about 78mm is bent into 22 U-shaped curved tapers (Pagoda-shaped) heat exchanger tube, the technique through new, can once bend moulding, can save 22 solder joints and material consumption, 1 welder, 1 underworker.
2, improved production efficiency: as a long pipe of about 78mm is bent into 22 U-shaped curved tapers (Pagoda-shaped) heat exchanger tube, the cancellation of 22 assembly welding point operations, not only saved material cost, and saved that blanking, groove are made, group is to, welding, carrying out flaw detection and pressure testing the test procedure, therefore every product has been saved the time of about at least 5 days.
3, saving equipment: use this technique, needn't increase special equipment, both saved equipment funds input, saved again place and personnel.
Accompanying drawing explanation
Fig. 1 is the size schematic diagram that bends of the present invention.
Fig. 2 is the crooked schematic diagram of one-shot forming of the present invention.
The specific embodiment
Referring to accompanying drawing, the process that a kind of taper heat exchanger tube bends, carry out according to the following steps successively:
First, the former grinding tool R wheel of universal bending machine is increased to 10mm height, tube grip grinding tool improves certain altitude 10mm, and push rod oil sealing reduces height 5mm; Secondly, institute's straight tube is put into grinding tool, by flow process, clamp and arrange angle;
Then, release the button that it is U-shaped curved to start to bend, first measurement size A, clamps back elbow, finds out R center after completing, and size up B, clamp back elbow, after completing, find out R center, and size up C, clamp back elbow, after completing, find out R center, and size up D, and bend down according to this.
