Description

Technical Field

[0001] This utility model relates to the technical field of processing equipment for highway guardrail production, specifically a processing equipment for highway guardrail production with precise hole positioning. Background Technology

[0002] The production of highway guardrails requires a large number of drilling operations to facilitate assembly. Perforation machines are commonly used for perforation of highway guardrails. Perforation machines use hydraulic power to generate strong punching force, which, together with dies, performs continuous punching operations on the highway guardrails to achieve the punching process.

[0003] Currently, in existing technologies, highway guardrails are usually long tubular fittings. When drilling holes, manual assistance is required to feed the material to facilitate continuous punching by the punching machine. However, manual feeding results in inaccurate hole positioning in highway guardrails. Therefore, there is a need to propose a processing device for highway guardrail production with precise hole positioning. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the inaccurate hole placement in highway guardrails caused by the use of punching machines with manual feeding, this invention proposes a processing device for highway guardrail production with precise hole positioning.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a processing device for highway guardrail production with accurate hole positioning, including an operating table, a guide platform is provided on the top of the operating table, a punching machine is fixedly connected to one end of the top of the operating table near the guide platform, a punching mold is provided on the top of the guide platform near the punching machine, and an intermittent feeding mechanism is provided at the bottom of the guide platform. The intermittent feeding mechanism includes a first guide rail, which is fixedly connected to the top of the operating table. A slide table is slidably connected to the top of the first guide rail. A first cylinder is provided on one side of the slide table. A second guide rail is fixedly connected to the top of the slide table. Side plates are slidably connected to both sides of the top of the second guide rail. A clamping plate is fixedly connected to the top of the side plate. A second cylinder is provided on the opposite side of the side plate. A connecting rod is provided at the bottom of the side plate. A swing rod is provided at one end of the connecting rod.

[0006] Preferably, a first slider is slidably connected to the top of the first guide rail, and the slide table is fixedly connected to the top of the first slider.

[0008] Preferably, a second slider is slidably connected to the top of the second guide rail, and the side plate is fixedly connected to the top of the second slider.

[0009] Preferably, the middle part of the swing arm is rotatably connected to the top of the operating table, and the end of the swing arm is rotatably connected to the end of the connecting rod.

[0010] Preferably, a support plate is fixedly connected to the bottom of the guide platform, and the support plate is fixedly connected to the top of the operating table.

[0011] Preferably, the top of the guide platform is provided with a guide groove, and the punching die is fixedly connected inside the guide groove.

[0012] The advantages of this utility model are: This invention introduces highway guardrail pipe fittings onto a guide platform and inserts them into a punching die. A punching machine, in conjunction with the punching die, positions the longitudinal holes of the highway guardrail pipe fittings. An intermittent feeding mechanism provides intermittent feeding to position the transverse holes. A second cylinder pushes a side plate to slide inward, causing the side plates to clamp the highway guardrail pipe fittings inward.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a processing device for highway guardrail production with precise hole positioning. (Refer to...) Figures 1-5 A processing device for producing highway guardrails with precise hole positioning includes an operating table 1, a guide platform 2 on the top of the operating table 1, a punching machine 4 fixedly connected to one end of the top of the operating table 1 near the guide platform 2, a punching die 41 on the top of the guide platform 2 near the punching machine 4, and an intermittent feeding mechanism 3 at the bottom of the guide platform 2. By pushing the highway guardrail pipe fittings onto the guide platform 2 and inserting them into the punching die 41, the punching machine 4, in conjunction with the punching die 41, can accurately position the longitudinal holes of the highway guardrail. The intermittent feeding mechanism 3 reciprocates to push the highway guardrail pipe fittings for intermittent feeding, so that the punching machine 4 and the intermittent feeding mechanism 3 work together to continuously punch, thereby accurately positioning the transverse holes of the highway guardrail pipe fittings, thus achieving the purpose of precise hole positioning of the highway guardrail pipe fittings. The intermittent feeding mechanism 3 includes a first guide rail 31, which is fixedly connected to the top of the operating table 1. A slide table 33 is slidably connected to the top of the first guide rail 31. A first cylinder 38 is provided on one side of the slide table 33. A second guide rail 34 is fixedly connected to the top of the slide table 33. Side plates 36 are slidably connected to both sides of the top of the second guide rail 34. A clamping plate 37 is fixedly connected to the top of the side plates 36. A second cylinder 39 is provided on the opposite side of the side plates 36. A connecting rod 310 is provided at the bottom of the side plates 36. A swing rod 311 is provided at one end of the connecting rod 310. The second cylinder 39 pulls the side plates 36 on both sides to slide inward, and the side plates 36 are located on the second guide rail 34. Stable sliding occurs when the side plates 36 on both sides slide relative to each other through the connecting rod 310 and the swing rod 311. This causes the side plates 36 to drive the clamping plates 37 on both sides to clamp the highway guardrail pipe fittings inward. The first cylinder 38 pushes the slide table 33, which slides stably on the first guide rail 31. The slide table 33 drives the clamping plates 37 and the highway guardrail pipe fittings forward for feeding. When feeding is complete, the punching machine 4 punches holes. Then, the second cylinder 39 drives the clamping plates 37 to release the clamping of the highway guardrail pipe fittings, and the first cylinder 38 drives the slide table 33 to return to the initial position. This repetition achieves the purpose of intermittent feeding of the highway guardrail pipe fittings.

[0018] Reference Figure 2 , Figure 3 and Figure 5 A first slider 32 is slidably connected to the top of the first guide rail 31, a slide table 33 is fixedly connected to the top of the first slider 32, a first cylinder 38 is fixedly connected to the top of the operating table 1, and the end of the telescopic shaft of the first cylinder 38 is fixedly connected to one side of the slide table 33. A second slider 35 is slidably connected to the top of the second guide rail 34, a side plate 36 is fixedly connected to the top of the second slider 35, and a swing rod 311 is rotatably connected to the top of the operating table 1 at its middle section. The end of the swing rod 311 is rotatably connected to the end of the connecting rod 310. The second cylinder 39 pushes the side plate 36, which slides stably in conjunction with the second guide rail 34 and the second slider 35. The sliding of the side plate 36 drives the connecting rod 310 to rotate. The connecting rods 310 at both ends rotate synchronously with the swing rod 311, so that the side plate 36 can drive the clamping plate 37 to slide synchronously and stably clamp the highway guardrail pipe. The first cylinder 38 pushes the slide table 33, which slides stably in conjunction with the first slider 32 and the first guide rail 31, so that the slide table 33 can drive the clamping plate 37 to slide back and forth.

[0019] Reference Figure 1 and Figure 4A support plate 22 is fixedly connected to the bottom of the guide platform 2. The support plate 22 is fixedly connected to the top of the operating table 1. A guide groove 21 is opened on the top of the guide platform 2. The punching die 41 is fixedly connected inside the guide groove 21. By supporting the guide platform 2 stably with the support plate 22, the guide platform 2 can be suspended on the operating table 1. The highway guardrail pipe is pushed into the guide groove 21 on the guide platform 2, and one end of the highway guardrail pipe is inserted into the punching die 41. The highway guardrail pipe can be stably fed into the punching die 41 along the guide groove 21.

[0020] Working principle: During use, the highway guardrail pipe fitting is pushed onto the guide platform 2. The support plate 22 supports the guide platform 2 in mid-air. The highway guardrail pipe fitting slides along the guide groove 21 and is inserted into the punching die 41. The punching machine 4 on the operating table 1, in conjunction with the punching die 41, can accurately position the longitudinal hole of the highway guardrail pipe fitting. The intermittent feeding mechanism 3, in conjunction with the punching machine 4, continuously punches holes. The second cylinder 39 pushes the side plate 36 to slide. The side plate 36, in conjunction with the second guide rail 34 and the second slider 35, slides stably. The side plates 36 on both sides slide synchronously in conjunction with the connecting rod 310 and the swing rod 311, so that... The side plate 36 can drive the clamping plate 37 to clamp the highway guardrail pipe inward. The first cylinder 38 drives the slide table 33 to move. The slide table 33, in conjunction with the first guide rail 31 and the first slider 32, slides stably and drives the clamping plate 37 and the highway guardrail pipe forward for feeding. When the feeding is completed, the punching machine 4 punches a hole once. Then the second cylinder 39 pushes the clamping plate 37 to release the clamping of the highway guardrail pipe. The first cylinder 38 drives the slide table 33 to return to the initial position. This process is repeated to achieve the purpose of intermittent feeding of the guardrail pipe, so that the punching machine 4 can accurately position the lateral hole of the highway guardrail pipe.
