Description

Technical Field

[0001] This utility model relates to the technical field of processing equipment for elastic clamps for railway turnouts, specifically, to a forming mold for elastic clamps for heavy-duty railway turnouts. Background Technology

[0002] The elastic clamp for track turnouts (also known as elastic clamps, turnout elastic clamps, etc.) is one of the important components used to fix and connect turnout parts. It is usually made of elastic materials, such as spring steel. The elastic clamp plays a role in fixing, connecting, damping and compensating in track turnouts, ensuring the safety, stability and smoothness of the turnout when trains pass.

[0003] One step in the molding process of the elastic clip is to press the elastic clip into shape on a press. However, the current processing molds are usually only suitable for processing elastic clips of a single size. When processing elastic clips of different models, the entire set of molds needs to be changed, which is quite inconvenient. Utility Model Content

[0004] Therefore, this utility model proposes a molding die for elastic clips used in heavy-duty track turnouts, which can be applied to the processing of elastic clips of different models.

[0005] The technical solution of this utility model is as follows:

[0006] A flexible clamp forming mold for heavy-duty railway turnouts, used for mounting on a press, comprising:

[0007] The base is fixed to the lower template of the press.

[0008] The elastic clip placement part includes two mounting blocks fixed on the base. Two support blocks for supporting two side walls of the elastic clip are fixed on the two mounting blocks respectively, and the fixed positions of the two support blocks on the corresponding mounting blocks can be adjusted along the width direction of the base.

[0009] The elastic clip forming part includes two forming blocks disposed on two opposite sides of the elastic clip placement part. Each of the two forming blocks is provided with a push unit. An elastic element is provided between the two forming blocks and the base. The elastic element applies an elastic force to the corresponding forming block to move the forming block away from the elastic clip placement part.

[0010] The upper die of the press is provided with two stamping wedges corresponding to the two supporting units. When the lower die moves down, the two stamping wedges can push the corresponding supporting units to make the forming block slide along the length direction of the base and squeeze the elastic clamp to form the elastic clamp.

[0011] Furthermore, corresponding to each of the molding blocks, two guide holes are respectively opened on the base, and two guide posts are fixed on the molding block, and the two guide posts can slide in the two guide posts in a one-to-one correspondence.

[0012] Furthermore, the elastic element is a spring sleeved on the guide post and connected between the molding block and the base.

[0013] Furthermore, the supporting unit includes a pressure roller shaft fixed on the forming block and a pressure roller rotatably disposed on the pressure roller shaft. When the lower template moves down, the inclined surface of the stamping wedge can abut against the outer peripheral surface of the pressure roller.

[0014] Furthermore, corresponding to the two molding blocks, guide grooves are provided on the base on both opposite sides of the molding blocks, and sliders that can slide in the two guide grooves are provided on the molding blocks respectively.

[0015] Furthermore, corresponding to the two molding blocks, a limiting block is fixedly provided on the base, and a limiting hole extending along the sliding direction of the molding block is provided on the molding block, and the limiting block can be inserted into the limiting hole.

[0016] Furthermore, each of the two support blocks has an elongated hole extending along the width direction of the base, and the mounting block has a threaded hole, through which a bolt can pass and be screwed into the threaded hole.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] The elastic clamp forming mold for heavy-duty track turnouts provided by this utility model allows the fixed positions of the two support blocks on the corresponding mounting blocks to be adjusted along the width direction of the base, thereby making the forming mold more convenient for forming elastic clamps of different models.

Detailed Implementation

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] This embodiment provides a forming mold for a flexible clamp used in heavy-duty railway turnouts, hereinafter referred to as a forming mold, which is used to be mounted on a press. (Reference) Figure 1 and Figure 2 As shown, the molding die includes a base 100, an elastic clip placement part 200, an elastic clip forming part 300, and a stamping wedge 400. The base 100 is fixed to the lower template of the press and serves as the foundation for mounting other components; its structure will not be described in detail here. In this embodiment, the elastic clip placement part 200 includes two mounting blocks 210 fixed to the base 100. Each mounting block 210 has two support blocks 220 fixed to its respective sidewalls for supporting the elastic clip 500. The fixed positions of the two support blocks 220 on their respective mounting blocks 210 are adjustable along the width direction of the base 100.

[0025] The elastic clip forming part 300 of this embodiment includes two forming blocks 310 disposed on two opposite sides of the elastic clip placement part 200. Each of the two forming blocks 310 is provided with a supporting unit 320. An elastic element 330 is provided between the two forming blocks 310 and the base 100. The elastic element 330 applies an elastic force to the corresponding forming block 310, causing the forming block 310 to move away from the elastic clip placement part 200. Corresponding to the two supporting units 320, two stamping wedges 400 are provided on the upper template 600 of the press. When the lower template moves downward, the two stamping wedges 400 can push the corresponding supporting unit 320, causing the forming block 310 to slide along the length direction of the base 100 and compress the elastic clip 500 to form the elastic clip 500.

[0026] Based on the overall structure described above, the working process of the molding die in this embodiment is as follows: The elastic clip 500 to be molded is placed on the mounting block 210 of the elastic clip placement part 200, and two support blocks 220 are located between the two side walls of the elastic clip 500. When the upper platen 600 of the press moves downward, the stamping wedge 400, after contacting the corresponding pushing unit 320, will push the molding block 310 to move along the length direction of the base 100 until the molding block 310 contacts the elastic clip 500 and molds the elastic clip 500, thus completing the processing of the elastic clip 500. After the elastic clip 500 is formed and the stamping wedge 400 moves upward with the upper platen 600, the two molding blocks 310 can be driven back to their original position by the elastic element 330. By adjusting the fixed position of the two mounting blocks 210 on the mounting block 210 along the width direction of the base 100, the molding die can be used to mold different models of elastic clips 500.

[0027] In this embodiment, reference Figure 1 As shown, for each molding block 310, two guide holes are respectively opened on the base 100, and two guide posts 311 are fixed on the molding block 310. The two guide posts 311 can slide in the two guide posts 311 one by one. A limiting plate 312 is fixed on the end of the guide post 311 away from the molding block 310.

[0028] refer to Figure 1 As shown, the elastic element 330 is a spring sleeved on the guide post 311 and abutting between the base 100 and the limiting plate 312. Based on this structure, when the forming block 310 is pushed close to the elastic clamp 500 by the stamping wedge 400, the limiting plate 312 compresses the spring and stores energy; when the stamping wedge 400 disengages from the forming block 310, the limiting plate 312 and the forming block 310 will reset under the push of the spring. In some embodiments, the elastic element 330 may also be other elastic components. In this embodiment, the guide post 311 is provided with an external thread, and the limiting plate 312 is provided with a threaded hole that is screwed into the external thread to facilitate the installation of the forming block 310 on the base 100.

[0029] This embodiment also provides a structurally superior support unit 320, see reference. Figure 1As shown, the pusher unit 320 in this embodiment includes a pressure roller shaft 321 fixed on the forming block 310 and a pressure roller 322 rotatably mounted on the pressure roller shaft 321. When the lower template moves downward, the inclined surface of the stamping wedge 400 can abut against the outer peripheral surface of the pressure roller 322. In this embodiment, by setting the pusher unit 320, when the inclined surface of the stamping wedge 400 contacts the outer peripheral surface of the pressure roller 322, the friction between the two is rolling friction, which can reduce the wear between the stamping wedge 400 and the pressure roller 322. In some embodiments, the pressure roller 322 can also be fixedly sleeved on the pressure roller shaft 321, and the pressure roller shaft 321 can be rotatably mounted on the forming block 310. In some embodiments, the pusher unit 320 can also be a wedge block fixed on the forming block 310, but when it contacts the stamping wedge 400, the friction between the two is sliding friction, which is more prone to wear.

[0030] In this embodiment, corresponding to the two molding blocks 310, guide grooves are provided on the base 100 on two opposite sides of the molding blocks 310, and sliders that can slide within the two guide grooves are provided on the molding blocks 310. By providing these guide grooves and sliders, the sliding of the molding blocks 310 on the base 100 can be guided. In some embodiments, two guide rails can also be laid on the base 100 for each molding block 310, and sliders that are adapted to the two guide rails can be provided on the molding blocks 310 to guide the sliding of the molding blocks 310.

[0031] refer to Figure 1 As shown, corresponding to the two molding blocks 310, limiting blocks are respectively fixed on the base 100, and limiting holes extending along the sliding direction of the molding block 310 are formed on the molding block 310, allowing the limiting blocks to be inserted into the limiting holes. In this embodiment, by setting the aforementioned limiting holes and limiting blocks, when the molding block 310 slides to the point where the two sidewalls of the limiting holes abut against the limiting blocks, the limiting blocks can prevent the molding block 310 from continuing to move. That is, the limiting blocks constitute a bidirectional limiting of the movement of the molding block 310.

[0032] In this embodiment, reference Figure 1 As shown, elongated holes 201 extending along the width direction of the base 100 are respectively provided on the two support blocks 220, and threaded holes are provided on the mounting block 210, allowing bolts to pass through the elongated holes 201 and be screwed into the threaded holes. The position of the support blocks 220 can be adjusted along the width direction of the base 100 by having the bolts pass through different positions of the elongated holes 201. It should be noted that the structure of the two support blocks 220 used to support the two side walls of the elastic clamp 500 and form the elastic clamp 500 can refer to existing technology, and will not be described in detail here.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
