Description

Technical Field

[0001] The utility model relates to the technical field of crawler production, in particular to a simple small crawler integral preforming machine. Background Art

[0002] Rubber tracks are made of rubber and skeleton materials and are widely used in engineering machinery and agricultural machinery. The track preforming machine is a device used to manufacture tracks. It is mainly used to process the pre-treated winding steel belt, pre-formed belt body and filled rubber block raw materials through the mold closing and vulcanization process to finally complete the production of semi-finished tracks.

[0003] In the existing technology, most track integral preforming machines are unable to tension the placed track blanks when in use, resulting in insufficient tension of the track blanks, making the track blanks easy to relax during the vulcanization process, and then causing the size of the vulcanized track to be unstable, affecting its use effect. In addition, if the track is too loose, it will lead to uneven vulcanization, affecting the physical properties and durability of the track, and the practicality is insufficient. Therefore, it is necessary to redesign a simple and small track integral preforming machine to address the above problems. Utility Model Content

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Preferably, the lifting mechanism includes a lifting cylinder fixedly mounted on the upper end surface of the frame, and the telescopic end of the lifting cylinder is fixedly connected to the upper end surface of the press.

[0008] Preferably, the first sliding mechanism includes two first sliding rails fixedly mounted on the inner wall of the first support frame, a first slider is slidably mounted inside the two first sliding rails, and ends of the two first sliders are fixedly connected to the outer wall of the first installation frame.

[0009] Preferably, the lifting mechanism includes a lifting motor fixedly installed inside the first support frame, and the telescopic end of the lifting motor is fixedly connected to the bottom wall of the upper lifting block.

[0010] Preferably, the second sliding mechanism includes two second slide rails fixedly mounted on the upper end surface of the second support frame, a second slider is slidably mounted inside the two second slide rails, and ends of the two second sliders are fixedly connected to the bottom wall of the mounting frame.

[0011] Preferably, a patterned rubber guiding device is fixedly installed on the outer wall of the frame, and a steel wire lifting device is fixedly installed on the outer wall of the frame through a lifting cylinder.

[0012] Beneficial effects of the utility model:

[0013] 1. By setting up components such as a screw rod, a rotating motor and a mounting frame, the rotating motor can drive the screw rod to rotate. When the screw rod rotates, the mounting frame can be driven to move through the moving block. At this time, the mounting frame can slide in the second slide rail through the second slider, thereby driving the second tensioning roller to move through the second mounting frame. At this time, the second tensioning roller can pull and tension the rubber track blank.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-6 A simple small crawler integral preforming machine includes a frame 1, a hydraulic system 2 is fixedly installed on the upper end surface of the frame 1, the upper end surface of the frame 1 is fixedly connected to a press 4 through a lifting mechanism, the lifting mechanism includes a lifting cylinder 3 fixedly installed on the upper end surface of the frame 1, the telescopic end of the lifting cylinder 3 is fixedly connected to the upper end surface of the press 4, the telescopic end of the press 4 is fixedly connected to an upper beam pressing plate 5, a pattern glue guide device 6 is fixedly installed on the outer wall of the frame 1, and a steel wire lifting device 7 is fixedly installed on the outer wall of the frame 1 through a lifting cylinder.

[0024] The side wall of the frame 1 is fixedly mounted with a lower machine base 8, and the outer wall of the lower machine base 8 is fixedly mounted with a wheel side glue guide device 9. A first support frame 10 is fixedly mounted on the outer wall of one side of the lower machine base 8, and a second support frame 11 is fixedly mounted on the outer wall of the other side of the lower machine base 8. The outer wall of the first support frame 10 is slidably mounted with a first mounting frame through a first sliding mechanism. The first sliding mechanism includes two first slide rails 12 fixedly mounted on the inner wall of the first support frame 10, and the first sliders are slidably mounted inside the two first slide rails 12. The ends of the two first sliders are fixedly connected to the outer wall of the first mounting frame. A first tensioning roller 13 is fixedly mounted inside the first mounting frame, and an upper top block 15 is fixedly mounted inside the first support frame 10 through an upper top mechanism. The upper top mechanism includes a lifting motor 14 fixedly mounted inside the first support frame 10, and the telescopic end of the lifting motor 14 is fixedly connected to the bottom wall of the upper top block 15.

[0025] The upper end surface of the second support frame 11 is slidably installed with a mounting frame 17 through a second sliding mechanism. The second sliding mechanism includes two second slide rails 16 fixedly installed on the upper end surface of the second support frame 11. Second sliders are slidably installed inside the two second slide rails 16. The ends of the two second sliders are fixedly connected to the bottom wall of the mounting frame 17. A second tensioning roller 18 is fixedly installed on the outer wall of the mounting frame 17 through a second mounting frame. A screw rod 19 is rotatably installed inside the second support frame 11. A rotating motor 20 connected to the screw rod 19 is fixedly installed on the outer wall of the second support frame 11. A moving block is threadedly installed on the outer wall of the screw rod 19, and the end of the moving block is fixedly connected to the bottom wall of the mounting frame 17.

[0026] When the present invention is used, the workpiece is placed on the upper end surface of the lower machine base 8.

[0027] At the same time, the lifting motor 14 can drive the upper top block 15 to move upward and squeeze the first mounting frame. At this time, the first mounting frame is subjected to force to drive the first slider to move upward inside the first slide rail 12, so that the height of the first tensioning roller 13 can be conveniently adjusted, and in the process of steel wire extrusion, the lifting cylinder can drive the steel wire lifting device 7 to lift the steel wire, thereby ensuring that the steel cord remains neatly arranged during the extrusion process, avoiding bending, overlapping or breaking, thereby ensuring the strength and durability of the track, and avoiding breakage or damage during use. Before vulcanizing the rubber track blank, the pattern rubber guide device 6 and the wheel side rubber guide device 9 can separate the pattern rubber and the wheel side rubber, thereby avoiding cracks in the pattern rubber and the wheel side rubber during the vulcanization process.
