Description
[technical field]
The utility model relates to a kind of horizontal type tube expanding machine.
[background technology]
The air conditioner production industry is in the process of producing heat exchanger of air condition, it is that numerous copper pipes of heat exchanger are processed that one procedure is arranged: be that the copper pipe diameter is swollen on the one hand, make it fully to contact, increase heat transfer efficiency, simultaneously fin is fixed with aluminium heat sink; In addition, also will swell into the cup-shaped of band bell edge to the copper pipe head, the copper pipe that is beneficial to other butt joints of next procedure inserts.The employed machine of this procedure is referred to as electric tube expander, if processed heat exchanger is relatively grown up, only is beneficial to processing under the state of couching, and employed machine then is called " horizontal type tube expanding machine ".
The domestic existing horizontal type tube expanding machine that appears on the market is a fluid pressure type.Its structure is seen Fig. 1, comprises an expander roll die holder 5 that is driven by oil cylinder 4, and the expander roll die holder is provided with and copper pipe 9 axial corresponding expander rolls 6, and in the stroke of expander roll die holder, expander roll can insert from the port of copper pipe, realizes the expansion to whole copper pipe diameter; Be provided with movable drift die holder on the stroke of expander roll die holder, the drift die holder is provided with the drift that is axially worn by the expander roll work, makes the drift die holder under the promotion of expander roll die holder, and drift can insert copper pipe end, realizes the expansion to copper pipe end.During work, motor 1 drives oil pump 2 and produces pressure oil liquid, drives oil cylinder 4, and piston rod promotes expander roll die holder 5, and the expander roll 6 that is contained on the expander roll die holder is moved.Expander roll enters copper pipe 9 and carries out expander roll, and when the expander roll head advanced near the copper pipe afterbody, expander roll die holder 5 contacted with drift die holder 7.This moment, expander roll die holder 5 was also in the continuation promotion, so promotion drift die holder 7 related drifts 8 are advanced to the copper pipe direction together.When expander roll die holder 5 advanced to the terminal point extreme position, just in time copper pipe 9 head punching out cup-shapeds, expander roll 6 heads were also just in time gone to copper pipe 9 tail ends to drift 8, afterwards, solenoid directional control valve 3 commutations, expander roll 6 and drift 8 are hauled out in the oil cylinder piston counter motion, and operation is finished.
Have following shortcoming: when expander roll swelled the copper pipe diameter, the copper pipe axial direction can produce a certain amount of contraction.This is inevitable.Because more or less there are some differences in copper pipe size, material, the club head diameter dimension that rises, so every copper pipe is all different in the amount of contraction of length direction.So it is uneven to show as copper pipe head height.Charge and attack the cup-shaped of copper mouth piece this moment, and the tube head that exceeds may be shaped too dark, causes oral area to break; Short tube head possibility aplasia needs manual dashing one by one to mend shaping.Certainly will have influence on product quality and production efficiency like this.Have again, when processing the heat exchanger of different size, need to adjust mechanical device position, many places, time-consuming and difficult grasp.
[utility model content]
The utility model purpose be to provide a kind of than existing horizontal type tube expanding machine to the copper mouth piece program control double dynamical horizontal type tube expanding machine more reliable and that be convenient to adjust that is shaped.
The program control double dynamical horizontal type tube expanding machine of the utility model design, but the expander roll die holder that comprises a move left and right on bearing, the expander roll die holder is provided with the expander roll of aiming at copper pipe, but the drift die holder that also comprises a move left and right on bearing, this drift die holder is provided with the drift that is axially worn by the expander roll work, described drift is in the stroke of drift die holder, can insert copper pipe end, realization is to the expansion of copper pipe end, it is characterized in that: described drift die holder is provided with a big wire role parallel with expander roll, and described big wire role is driven by a numerical-control motor and moves axially; Other is provided with by another numerical-control motor and drives and the minor leading screw that rotates, be arranged in parallel with expander roll, and is connected with nut on the expander roll die holder, and described two numerical-control motors are controlled by setting working procedure by microcomputer.
Further improvement as such scheme, it is characterized in that bearing be provided with two parallel with expander roll and can be along the guide pillar of bearing move left and right, and be listed in the both sides up and down of expander roll, the one end connects the drift die holder, the other end then is connected with crossbeam, and described big wire role one end is connected on the crossbeam.
Further improvement as such scheme, it is characterized in that: the expander roll die holder is provided with two perforation that are enclosed within on two guide pillars, make the expander roll die holder along guide pillar move left and right on bearing, the above-mentioned minor leading screw that is driven by numerical-control motor has two, respectively and be listed in the both sides up and down of expander roll, the nut that connects with minor leading screw on the expander roll die holder is corresponding to be provided with two.
Operation principle of the present utility model and advantage are such: the utility model drives expander roll die holder and drift die holder respectively with two numerical control electric machines of microcomputer control, realizes expand tube and the action that charges and attacks tube head respectively.The priority of two secondary moulds (expander roll die holder and drift die holder) operation, speed, stroke all can be set on microcomputer as required separately, can obtain optimum parameter.So the forming quality of tube head is better than existing horizontal type tube expanding machine greatly.Be actually and improved production efficiency and product quality.Owing to be microcomputer control,, only need on the control box of microcomputer, preset parameters to be accessed simultaneously, just can produce immediately, by hand electric tube expander is not done the position adjustment for the heat exchanger of different size (copper pipe length difference).Overall process is convenient, fast, reliable.
