Description

Heat pipe forming machine

The utility model relates to a pipe forming machine tool, in particular to a heat pipe sealing forming machine which can save space and increase production speed.

The existing heat pipe forming machine is shown in Figure 1-3: there is a console 11 on the front side of its long body 1, and there is a row of multiple control buttons 12 on it, corresponding to the row of multiple control buttons set in the machine 1. 12, corresponding to a row of multiple branch vacuum manifolds 13 set in the machine 1, each vacuum manifold 13 is connected to a main rod vacuum manifold 14, and the main rod vacuum manifold 14 is connected to a vacuum pump 15, and the vacuum pumps 15 pairs Each manifold generates vacuum suction, and each branch vacuum manifold 13 is arranged neatly, and the lower end is vertically downward, and a pipe clamping assembly 16 is connected to the lower end to socket a heat pipe 4 . The heat pipe is a short thin tube, preferably a copper tube and has a pre-process. In the pre-process stage, the tube is cleaned first, and then a special liquid is put in to guide the flowing components. At this time, the heat pipe is a semi-finished product. Because the heat pipe is in a vacuum The capillary phenomenon can only be produced under the heat pipe, and the heat pipe semi-finished product is vacuum sealed. This mechanism, when the heat pipe 4 semi-finished product is received by the clamping assembly 16 of the branch vacuum manifold 13, the control button 12 is pressed to open a solenoid valve 17 of the branch vacuum manifold 13, and it takes a long time to vacuumize, as shown in the figure It takes about 3-5 minutes to vacuumize at fourteen stations, or at twenty stations. In this way, during this period, the heat pipe semi-finished product to the clamping assembly cannot be automated yet, and manual erection is required, resulting in manpower consumption. In addition, there is a guide rail 18 at the rear of the clamping assembly 16, on which a slide block 181 is connected with a pressing mechanism 19 and a shearing mechanism 191 and a welding mechanism 192 driven by a pneumatic cylinder; , shearing, and welding are all only a single group of structures, which can only move left and right along the guide rail 18. At each station where the air extraction is completed, a pair of briquetting blocks of the pressing mechanism 19 will be used to produce a finished process with a hydraulic structure. To seal the heat pipe, first press it temporarily. If it is not sealed after the time limit, the vacuum degree will be lost. After pressing, the pipe head is cut off, that is, the cutting mechanism 191 of the slider 181 automatically cuts it, and then welds and seals it. finished product. When the operator completes the semi-finished product at the first station and turns back at the last position, he can go to the first station to loosen the clamping assembly and take off the finished heat pipe, so that he can switch between the finished product and the semi-finished product at every other station, but it is limited to the vacuum operation time, only It can extend the interval time and use multiple sets of the same suction device to wait for the vacuum operation time, resulting in a body length of up to four meters. The body is too large, and the operation channel is added, which makes the operator move a long distance, which is very uneconomical and difficult to operate. Inconvenient, in addition, the stability of vacuum operation is poor, and the defective rate of products increases. And the body is huge, so that the production speed is reduced.

The purpose of the utility model is to provide a heat pipe forming machine which saves the space occupied by the equipment and improves the production speed and product quality.

The purpose of this utility model is achieved in this way: heat pipe molding machine, which includes: a machine, a top plate, a vacuum manifold, a welding torch and a turntable; The supporting rod around the top surface of the table is elevated; connected to the vacuum manifold; the vacuum manifold is connected to a vacuum pump, and one end is provided with a clamping mechanism for clamping the heat pipe; the welding torch is located on the top plate and connected to a welding machine, and the turntable is Driven by a motor installed in the machine table, each work station has a support piece on the surface of the turntable on the top surface of the machine table; the top plate of the support piece is provided with a pressing mechanism and a shearing mechanism.

In the above design, the pressing mechanism presses the upper end of the heat pipe, and the shearing mechanism cuts off the end of the heat pipe. When the turntable is vacuumed at a workstation, the pressing and cutting are performed at the workstation, and the turntable moves to the next workstation for welding, so that the vacuum manifold and welding torch are on the top plate. The spaced workstations on the top perform four-stage operations of clamping the upper tube, vacuum extraction, pressing and cutting, spot welding and releasing the clamping, which achieves the effects of less equipment occupation, fast production speed and high product quality.
