Abstract
The invention discloses the process that a kind of taper heat exchanger tube bends, sequentially include the following steps: first successively, former for universal bending machine grinding tool R wheel is increased 10mm height, and tube grip grinding tool improves certain altitude (10mm), and certain altitude (5mm) is down to by push rod oil sealing；Secondly, institute's straight tube is put into grinding tool, clamps by flow process and angle is set；There is provided taper heat exchanger tube once bend moulding technique, it can one-shot forming, improve efficiency, reduce processing cost, it is ensured that quality.
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 particularly relating to heat exchanger once bends the device of molding.
Background technology
The universal bending machine that bends that at present oil, chemical machinery, the heat exchanger tube such as medical change only can serve as bending rectangle, square and single U-tube, and the general original process method that taper (Pagoda-shaped) pipe bends be bend after the single U-tube 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 ensure, the most inefficient.
Summary of the invention
The object of the invention is contemplated to solve universal bending machine and can not bend taper heat exchanger tube and bend the defect of technology, it is provided that taper heat exchanger tube once bends moulding technique, it can one-shot forming, improve efficiency, reduce processing cost, it is ensured that quality.
The present invention is achieved by the following technical solutions:
The process that a kind of taper heat exchanger tube bends, sequentially includes the following steps: successively
First, former for universal bending machine grinding tool R wheel being increased 10mm height, tube grip grinding tool improves certain altitude 10mm, and push rod oil sealing reduces height 5mm；
Secondly, straight tube is put into grinding tool, clamps by flow process and angle is set；
Then, releasing the button, 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, clamping back elbow, finds out R center, and size up D, and bends down according to this after completing.
The present invention, by by transforming universal bending machine grinding tool frock, cancels the operation such as assembly welding and detection of existing technique, uses and once bends molding technical matters taper (Pagoda-shaped) heat exchanger tube is bent one-shot forming.
The invention have the advantage that
1, cost-effective: as the pipe of an about 78mm length is bent into 22 U-shaped curved taper (Pagoda-shaped) heat exchanger tubes, through new technique, can once to bend molding, it is possible to save 22 solder joints and material consumption, 1 welder, 1 underworker.
2, improve production efficiency: as the pipe of an about 78mm length is bent into 22 U-shaped curved taper (Pagoda-shaped) heat exchanger tubes, the cancellation of 22 assembly welding point operations, not only save material cost, and saved blanking, groove makes, group to, welding, carrying out flaw detection and pressure testing the test procedure, therefore every product has saved the time of about at least 5 days.
3, equipment is saved: use this technique, it is not necessary to increase special equipment, both saved equipment funds input, and saved again place and personnel.
Accompanying drawing explanation
Fig. 1 be the present invention bend scale diagrams.
Fig. 2 is the one-shot forming bending schematic diagram of the present invention.
Detailed description of the invention
See accompanying drawing, the process that a kind of taper heat exchanger tube bends, sequentially include the following steps: successively
First, former for universal bending machine grinding tool R wheel being increased 10mm height, tube grip grinding tool improves certain altitude 10mm, and push rod oil sealing reduces height 5mm；Secondly, straight tube is put into grinding tool, clamps by flow process and angle is set；
Then, releasing the button, 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, clamping back elbow, finds out R center, and size up D, and bends down according to this after completing.
