The films 10 stacked on the pre-swing mechanism 1 are transferred to the lower template 22 of the pressing mechanism 2 through the conveying mechanism, and are pressed and shaped between the upper template 21 and the lower template 22 .

Through the above scheme, an independent placement station for the rubber belt and the metal piece 1b is set. During the processing, the rubber belt and the metal piece 1b are placed in advance. The probability that the track pressure equipment will cause injury to the staff, and at the same time ensure that the pressure equipment can continue to work at a better frequency; and the placement of the rubber belt are adjusted to reduce the placement effect of the metal part 1b and the rubber belt, thereby improving the product qualification rate and improving production efficiency.

In some embodiments, the conveying mechanism is horizontally installed in the pre-swing mechanism 1 and the pressing mechanism 2, and the films 10 stacked on the pre-swing mechanism 1 are automatically conveyed to the lower template 22 Automatically output after pressing and finalizing.

The films 10 stacked on the pre-swing mechanism 1 are automatically conveyed to the lower template 22 by the conveying mechanism passing through the pre-swing mechanism 1 and the pressing mechanism 2, and the upper template 21 and the lower template 22 Pressing and shaping between them makes the film 10 directly sent to the pressing structure after placement, without the need to transfer the film 10, which improves the processing tempo of the production line, thereby improving the production efficiency of the product.

Of course, in other embodiments, a transfer mechanism 5 that transfers the stacked films 10 to the pressing mechanism 2 as a whole may also be used, and this transfer mechanism 5 may be grasped by a robot.

In some embodiments, as shown in FIG. 3 , the pre-swing mechanism 1 and the pressing mechanism 2 are transitionally arranged side by side, one end of the conveying mechanism is installed at the input end of the pre-swing mechanism 1 , and the other One end is installed at the output end of the pressing mechanism 2 .

The transitional pre-swing mechanism 1 and the pressing mechanism 2 improve the continuity of the action of the pre-swinging mechanism 1 and the pressing mechanism 2, and at the same time improve the transportation stability of the film 10 on the conveying mechanism, thereby improving the production quality of the product. While improving production efficiency, reduce the defective rate.

In some embodiments, as shown in FIG. 3 and FIG. 4 , the conveying mechanism includes two sets of conveying elements 31 arranged at intervals and several sets of driving rollers 32 for driving the conveying elements 31 to move.

The conveying member 31 is arranged on the pre-swing mechanism 1 and the lower template 22; in another embodiment, the conveying mechanism on the pre-swing mechanism 1 and the press-fitting mechanism can also be separately and transitionally arranged.

As shown in Figures 5 and 6, the drive roller set 32 includes a first drive roller set 321 installed at both ends of the feed-in and out-feed of the pre-swing mechanism 1 and a second drive roller installed at the output end of the pressing mechanism 2 Group 322.

The positioning templates 12 in the gaps reserved between them cause interference.

In some embodiments, the pre-swing mechanism 1 includes:

Operating machine 11;

The positioning template 12, the positioning template 12 is adapted to be arranged between two groups of the conveying parts 31, and a plurality of positioning grooves 121 adapted to the metal part 1b are arranged in pairs on it, and multiple pairs of the positioning grooves 121 are arranged according to preset spacing linear arrangement settings; and

The driving part 13 is used to drive the positioning template 12 to move so that the metal part 1 b is synchronously disengaged from the positioning groove 121 .

The metal parts 1b are placed at the preset placement distance. In the actual production process, the staff places the metal parts 1b one by one according to the corresponding positioning groove 121, while increasing the placement speed of the metal parts 1b. , reducing the placement error of the metal piece 1b, thereby improving the production quality.

As shown in Fig. 7 and Fig. 8, the driving part 13 can be two interlocking worm gear screw elevators, and of course other lifting structures that can realize the lifting and moving of the positioning template 12 can also be used.

Since the worm gear screw lifter can realize the self-locking function, after the positioning template 12 rises or falls to the designated position, it is not necessary to provide mechanical control to inhibit the movement of the positioning template 12, and the positioning template 12 can be realized through the self-locking function of the worm gear screw lifter. Stay at the corresponding position; thereby reducing energy consumption and improving the use effect of the track metal part 1b positioning tool.

During use, the preformed track to be pressed is placed on the lower template 22, and the power part 23 of the pressing mechanism 2 drives the upper template 21 to move toward the lower template 22 to help the film 10 to be integrally formed; With the assistance of the demoulding mechanism 24, the thimble 241 exerts force on the preformed track that has been pressed and adsorbed on the upper formwork 21, and pushes the preformed track toward the side of the lower formwork 22, so that the preformed track can be detached from the upper formwork faster 21, in order to send the shaped preformed track to the subsequent station of the production line, thereby improving the production efficiency of the preformed track.

In some embodiments, the thimble 241 is detachably connected to the driving end of the corresponding power unit 242 .

The driving end of the power unit 22 is a sleeve structure with threads on the inner wall, and the thimble 241 is threaded on the driving end; of course, other detachable connection methods such as snap-fitting can also be used for the connection method, thereby increasing the versatility of the thimble 241. At the same time, the detachable thimble 241 structure facilitates the maintenance of the thimble 241 .

As shown in Figure 11 , wherein, the demoulding mechanism 24 is positioned at the middle part of the upper formwork 21, so that a plurality of guide holes 222 for passing the ejector pins 241 are close to the middle part of the upper formwork 21. Due to the metal part 1b in the middle of the track, the center of gravity of the track is biased towards the center, so that the weight of the track itself cooperates with the thimble 241 to make it easier to demould the track.

In some embodiments, several of the power units 242 are cylinders.

As shown in FIG. 11 , multiple power units 242 are controlled through the same air pipe, so that multiple power units 242 can work simultaneously, so that the track can be stressed more evenly, and the use effect of the thimble 241 can be improved.

As shown in Fig. 12, a mold is provided on the side of the upper template 21 close to the lower template 22, and a plurality of protrusions 221 are arranged on the mold, to illustrate by way of example, when the pressing mechanism 2 presses the preformed track, the A plurality of protrusions 221 on one side of the mold are respectively aligned with the metal part of the preformed track, and since the gap reserved between the protrusions 221 exerts a smaller force on the preformed track than the metal part, the preformed track is The bonding force at the gap is smaller than that of the metal parts, so that the demoulding mechanism 24 is easier to demould the preformed track, thereby improving the demoulding effect; at the same time, the chamfering setting of the protrusion 221 reduces the impact on the preformed track. The probability of damage caused by the molded track further improves the use effect of the mold.
