Description

Technical Field

[0001] The utility model relates to the technical field of elastic clip production, in particular to a rapid prototyping die for elastic clip production. Background Technique

[0002] In railway tracks, many different railway track fasteners are applied to assist in the installation, fixation and connection between tracks. Among them, the elastic clip fastener is a very common fastener. The railway track elastic clip refers to the fastening device part of the rail and the sleeper with an elastic clip.

[0003] When the existing railway track elastic clips are produced, the elastic clips are usually pressed into shape through three processes respectively. However, after each process is completed, the elastic clips need to be manually clamped and moved to the next process. Since the outer surface temperature of the elastic clips is relatively high, it is easy to scald the staff during the moving process, thus causing accidents. At the same time, the traditional three-process processing steps are relatively cumbersome and are not conducive to quickly forming the elastic clips. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rapid prototyping die for elastic clip production, so as to solve the problems that the outer surface temperature of the elastic clip is relatively high, it is easy to scald the staff during the moving process, thus causing accidents, and at the same time, the traditional three-process processing steps are relatively cumbersome and are not conducive to quickly forming the elastic clip as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a rapid prototyping die for elastic clip production, including a workbench, a fixed plate is fixedly connected to the inner side of the workbench, a connecting plate is fixedly connected to the outer surface of the fixed plate, a slider is slidably connected to the inner side of the connecting plate, a cylinder one is fixedly connected to the rear side of the fixed plate, and an output shaft of the cylinder one is fixedly connected to a fixed block.

A second fixing column is fixedly connected to the outer surface of the connecting frame below the first fixing column. A template is fixedly connected to the outer surfaces of the first fixing column and the second fixing column. A second cylinder is fixedly connected to the side surface of the connecting frame. The output shaft of the second cylinder is connected to a connecting shaft. A first push plate is fixedly connected to the outer surface of the connecting shaft.

The output shaft of the third cylinder is connected to a second push plate. A fourth cylinder is fixedly connected to the lower surface of the connecting frame. The output shaft of the fourth cylinder is connected to an adjusting plate. A limiting clamp is fixedly connected to the lower surface of the adjusting plate. A fifth cylinder is fixedly connected to the lower surface of the connecting frame near one side of the fourth cylinder. The output shaft of the fifth cylinder is hingedly connected to a third push plate. A sixth cylinder is fixedly connected to the upper surface of the workbench. The output shaft of the sixth cylinder is connected to a fourth push plate.

[0007] Preferably, both the fixing plate and the connecting plate are in a plate shape. Grooves adapted to the fixing plate and the connecting plate are formed on the upper surface of the workbench. The fixing plate and the connecting plate are fixedly connected to the inner side of the grooves. Rectangular grooves are formed on the inner sides of the fixing plate and the connecting plate. The fixing block is fixedly connected to the sliding block. By starting the first cylinder, the output shaft of the first cylinder extends and retracts, driving the fixing block to move upward at the rear side of the fixing plate, and then driving the sliding block to move upward inside the connecting plate, so as to move the raw material of the elastic strip above the workbench.

[0008] Preferably, both the fixing rod and the adjusting rod are in a cuboid rod shape. The inner side of the fixing rod is hollow. The adjusting rod is slidably connected to the inner side of the fixing rod. The spring is in a spiral shape. The spring is fixedly connected between the inner side of the fixing rod and the adjusting rod. The limiting plate is in a "U" - shaped plate shape. By starting the second cylinder, the output shaft of the connecting shaft extends and retracts, so that while the first push plate processes the raw material of the elastic strip, the limiting plate contacts the template more tightly, restricting the raw material of the elastic strip more tightly and facilitating the processing of the raw material of the elastic strip.

[0009] Preferably, the first push plate, the second push plate, the third push plate and the fourth push plate are all in a semi - cylindrical shape. The third push plate is hingedly connected to the output shaft of the fifth cylinder. By starting the second cylinder, the third cylinder, the fifth cylinder and the sixth cylinder, the first push plate, the second push plate, the third push plate and the fourth push plate process the raw material of the elastic strip, facilitating the rapid shaping of the raw material of the elastic strip.

[0010] Preferably, both the first fixing column and the second fixing column are cylindrical in shape, and both the first fixing column and the second fixing column are in two groups. The template is in an "M" shape, and its function is to facilitate the processing of the elastic strip raw material into an "M" shape through the template.

[0011] Preferably, the adjusting plate is in a plate shape. A groove adapted to the second push plate is provided in the middle of the upper surface of the adjusting plate. The limiting clip is in a semi-circular arc shape. Its function is to limit the elastic strip raw material through the limiting clip, and cooperate with the limiting plate to fixedly connect it to the middle of the template, facilitating the second push plate to process the elastic strip raw material.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By clamping the heated elastic strip raw material above the slider and then starting the first cylinder, the output shaft of the first cylinder extends and retracts, driving the fixed block to move upward at the rear of the fixed plate, thereby driving the slider to move upward inside the connecting plate, moving the elastic strip raw material above the workbench, facilitating subsequent processing of the heated elastic strip raw material, and thus eliminating the need for manual clamping and moving of the heated elastic strip raw material later, preventing burns to the staff.

[0014] 2. The slider moves the heated elastic strip raw material above the workbench. By starting the second cylinder, the output shaft of the connecting shaft extends and retracts, driving the first push plate to move towards the template. At the same time, the limiting plate restricts the elastic strip raw material to the middle part of the template. As the connecting shaft continues to extend and retract, the adjusting rod slides inside the fixed rod. Under the elastic action of the spring, the limiting plate contacts the template more tightly, thus restricting the elastic strip raw material more tightly. At the same time, the first push plate pushes the elastic strip raw material to bend. After bending, by starting the third cylinder and two groups of fourth cylinders, the output shafts of the third cylinder and the two groups of fourth cylinders extend and retract, causing the adjusting plate and the limiting clip to move downward, so that the limiting clip limits the elastic strip raw material and restricts it to the middle of the template. At the same time, the second push plate moves downward, pushing the elastic strip raw material to bend again. By starting the fifth cylinder, the output shaft of the fifth cylinder extends and retracts, driving the third push plate to push the elastic strip raw material to bend again, forming an "M" shape. By starting two groups of sixth cylinders, the output shafts of the two groups of sixth cylinders extend and retract, causing the two groups of fourth push plates to push the elastic strip raw material to bend, so that the elastic strip raw material is finally formed. After the processing is completed, it can be slid out of the template, thus improving the processing efficiency of the elastic strip raw material, eliminating the need for one-time pressing and forming, and saving processing time.

[0030] Working principle: A fixing plate 2 is fixedly connected to the inner side of the workbench 1. A connecting plate 3 is fixedly connected to the outer surface of the fixing plate 2. A slider 4 is slidably connected to the inner side of the connecting plate 3. A first cylinder 6 is fixedly connected to the rear side of the fixing plate 2. The output shaft of the first cylinder 6 is fixedly connected to a fixing block 5. By clamping the heated elastic strip raw material above the slider 4 and then starting the first cylinder 6, the output shaft of the first cylinder 6 is extended and retracted, thereby driving the fixing block 5 to move upward at the rear side of the fixing plate 2, thereby driving the slider 4 to move upward inside the connecting plate 3, thereby moving the elastic strip raw material above the workbench 1, facilitating the subsequent processing of the heated elastic strip raw material. Thus, it is no longer necessary for manual workers to hold and move the heated elastic strip raw material later, preventing burns to the workers.

[0031] The heated elastic bar raw material is moved above the workbench 1 by the slider 4. By starting the second cylinder 10, the output shaft of the connecting shaft 11 extends and retracts, thereby driving the first push plate 12 to move in the direction of the template 9. At the same time, the limiting plate 161 restricts the elastic bar raw material to the middle part of the template 9. As the connecting shaft 11 continues to extend and retract, the adjusting rod 16 slides inside the fixed rod 14. Under the elastic action of the spring 15, the limiting plate 161 contacts the template 9 more tightly, thereby restricting the elastic bar raw material more tightly. At the same time, the first push plate 12 pushes the elastic bar raw material to bend. At this time, by starting the third cylinder 17 and two groups of fourth cylinders 19, the output shafts of the third cylinder 17 and the two groups of fourth cylinders 19 extend and retract, so that the adjusting plate 20 and the limiting clamp 21 move downward, so that the limiting clamp 21 limits the elastic bar raw material and restricts it to the middle of the template 9. At the same time, the second push plate 18 moves downward, pushing the elastic bar raw material to bend again. Then, by starting the fifth cylinder 22, the output shaft of the fifth cylinder 22 extends and retracts, thereby driving the third push plate 23 to push the elastic bar raw material to bend again, forming an "M" shape. Then, by starting two groups of sixth cylinders 24, the output shafts of the two groups of sixth cylinders 24 extend and retract, so that the two groups of fourth push plates 25 push the elastic bar raw material to bend, so that the elastic bar raw material is finally formed. After the processing is completed, the formed elastic bar can be slid out from the template 9, thereby improving the processing efficiency of the elastic bar raw material and no longer requiring one-time pressing and forming, saving processing time.
