Description

Collector flat hole stamping device

[technical field]

The invention relates to a flat hole stamping device for a collecting pipe.

[Background technique]

At present, the automation of header processing equipment on the market is low, mainly including flat hole punching machine, spacer inserting machine, flat tube straightening and cutting machine and other machines. The existing flat hole punching machine includes a pipe fitting fixture fixed on the machine tool workbench and a punch for punching flat holes on the processed pipe fittings. Since the processed pipe fittings are fixed, in order to meet the processing accuracy requirements, the existing collecting pipe stamping flat holes adopts a one-time forming method, that is, the corresponding punch dies are set according to the required number of flat holes and the distance between each flat hole. All the flat holes on the pipe fittings are stamped at one time. Since the shape and size of the header and the flat hole on it have different requirements depending on the actual situation, and only rely on the existing punching machine to punch holes, various types of punch dies must be prepared, and the price of each set of dies is very high. , maintenance is also inconvenient, making the production cost of the existing header high. For this reason, it is necessary to improve the existing collecting tube flat hole stamping equipment.

As mentioned above, the flat hole stamping device of the collector is characterized in that the punch assembly includes a slider that can move up and down along the Y-axis direction and a servo motor for driving the slider to move, the slider is equipped with a punching knife, and the servo There is a crank connecting rod transmission mechanism between the motor output shaft and the slider;

As mentioned above, the flat hole stamping device for the collecting pipe is characterized in that there is one pipe clamp, the pipe clamp is fixedly arranged on the sliding seat, and the punch assembly is correspondingly provided with a punching knife, and the punching knife is located above the pipe clamp;

As mentioned above, the collecting tube flat hole stamping device is characterized in that there are multiple pipe fitting clamps, and each pipe fitting fixture is arranged on the sliding seat, and there are correspondingly a plurality of punching knives on the punch head assembly, and each punching knife is arranged side by side and located on the pipe fitting above the fixture;

As mentioned above, the flat hole stamping device for the header is characterized in that the servo drive device is a linear motor.

The beneficial effects of the present invention are:

1. Fix the pipe fittings on the fixture, and then the linear motor drives the sliding seat to slide left and right along the x-axis to position the punching knife on the punch head assembly relative to the punching position of the processed pipe fittings, punching holes in an orderly cycle, and realizing the punching position of the pipe fittings Accurate positioning can realize the automatic processing of different specifications of header pipe diameter, wall thickness and hole distance on the same machine tool. tube, all need to change the trouble of mold and tooling;

2. The present invention realizes the accurate positioning of the punching position of the pipe fittings, and punches holes in an orderly manner, so that the present invention can also cooperate with the spacer inserting machine to complete the process of inserting the spacer during the processing process, that is, when the punch assembly is on the processing tube, see When punching to the preset number of holes, the present invention suspends the punching process, and the spacer inserting machine starts to insert the spacer into the pipe, thereby avoiding the inconvenience of inserting the spacer after the processing is completed, and also overcomes the one-time punching process in the prior art. After the hole can only be opened again to put in the spacer and welded to seal the trouble.

[Detailed ways]

As shown in Figures 1-3, the flat hole stamping device for the header includes a pipe fixture 21 and a punch assembly 22 installed on the machine tool workbench 101, and the workbench 101 is also equipped with a driving pipe fixture 21 and a punch assembly 22 Relative translational translation mechanism 23, the translation mechanism 23 includes a sliding seat 231 that can translate left and right along the X-axis direction and a servo drive device 232 that drives the translational movement of the sliding seat 231, and one of the pipe fixture 21 and the punch assembly 22 is set On the sliding seat 231, the other is arranged on the frame 1, driven by the servo drive device 232, the punch assembly 22 and the pipe fixture 21 can move relatively, so that the punch assembly 22 can accurately and orderly punch holes on the processed pipe processing. In the present invention, one side of the workbench 101 is provided with a horizontal slide rail 106 along the X-axis direction, and the slide seat 231 is installed on the horizontal slide rail 106 . The servo drive device 232 is a linear motor.

The punch assembly 22 includes a slide rail 221 arranged along the Y-axis direction. A slide block 222 capable of sliding along it and a servo motor 224 for driving the slide block 222 to move are mounted on the slide rail 221. The slide block 222 is equipped with a punch. The hole cutter 223, the output shaft of the servo motor 224 and the slide block 222 are provided with a crank connecting rod transmission mechanism. In the present invention, the crank-link transmission mechanism includes an eccentric wheel 225 and a connecting rod 226. The eccentric wheel 225 is connected to the servo motor 224 through a belt.

As shown in FIGS. 1-3 , there is one pipe fixture 21 , and the pipe fixture 21 is fixedly arranged on the sliding seat 231 . The punch assembly 22 is correspondingly provided with a punching knife 223 , and the punching knife 223 is located above the pipe fixture 21 . In addition to the above-described embodiment, there may be multiple pipe fixtures 21 (not shown in the figure), each pipe fixture 21 is arranged side by side on the slide seat 231, and the punch assembly 22 is correspondingly provided with a plurality of punching knives 223 (in the figure). not shown), the punching knives 223 are arranged side by side and above the pipe fixture 21, so that simultaneous processing of multiple pipes can be realized, thereby improving processing efficiency.

The working process of the present invention is as follows:

The first step of loading: fixing the pipe fittings on the pipe fitting fixture 21 at the initial position of the slide seat 231 . Then the linear motor 232 drives the pipe clamp 21 to the right to translate to the designated position;

The second step of punching: the servo motor 224 starts to make the slide block 222 move downward from the top dead center. The motion trajectory of the slider 222 is divided into three positions: the upper dead point, the middle position, and the lower dead point. The sliding block 222 passes from the upper dead point downwards to the lower dead point, and then returns to the upper dead point as a cycle. The slider 222 goes from the top dead center down to the bottom dead point, that is, the punching is completed in 1/2 cycle, and two flangings are formed in the pipe, and then the linear motor 232 drives the pipe fitting fixture 21 to translate along the X-axis direction to the next designated position to prepare for punching again. Press in this way.

The third step blanking: stamping to the required number of holes, the servo motor 224 drives the slider 222 to stop at the top dead center, and the linear motor 232 drives the pipe clamp 21 to move leftwards and return to the initial position. When all have been finished, unclamp pipe fitting fixture 21, take material manually, and workpiece processing is finished.

Since the present invention can realize automatic and orderly control in the punching process, the present invention can cooperate with the spacer inserting machine to complete the operation of inserting the spacer during the processing, that is, when the punch assembly 22 is punched to the preset position on the processing tube, When the number of holes is fixed, the present invention suspends the punching process, and the spacer inserting machine is started to insert the spacer into the pipe fitting, thereby avoiding the inconvenience of inserting the spacer after the processing is completed, and also overcoming the problem of only one time punching in the prior art. The hassle of opening again to put in the spacer and welding to seal it.
