Description

Technical Field

[0001] This utility model relates to the field of guardrail processing technology, specifically a cutting device for guardrail production and processing. Background Technology

[0002] Cutting devices for guardrail production and processing refer to mechanical equipment specifically used in the guardrail manufacturing process to cut various raw materials required for guardrail production. They are mainly used to divide guardrail raw materials to obtain components of specific specifications required for subsequent processing and assembly into finished guardrail products.

[0003] A search revealed Chinese patent application CN202223531113.3, which discloses a cutting device for guardrail production and processing. Belonging to the field of guardrail production equipment, it includes an adjusting mechanism mounted on the upper end of a workbench for controlling the required cutting length of the raw material. The adjusting mechanism includes a positioning plate and a slider. This invention solves the problem that cutting devices lack the ability to position the required cutting length of the raw material, necessitating users to pre-determine the length using a measuring tape and marker, thus increasing the user's workload and reducing cutting efficiency. In this invention, the user moves the gears and chain by a handle, which in turn moves the slider and guide block. During movement, the required cutting length of the raw material can be controlled through the interaction between the indicator and the scale, eliminating the need for the user to pre-mark the cutting length of each piece of material.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In the existing technologies, the guardrail raw materials are fixed on the workbench and then cut by contact between the blade and the material. However, during the actual cutting process, the friction between the metals generates metal sparks, which can easily cause injury to nearby personnel. Furthermore, the sparks turn into metal fragments after cooling, and their irregular scattering makes subsequent cleaning very inconvenient and labor-intensive. Therefore, it is necessary to design a cutting device for guardrail production and processing that is highly practical and has the ability to limit, clean, and collect fragments.

[0023] 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 protection scope of the present utility model.

[0024] Please see Figure 1-4 The present invention provides a technical solution: a cutting device for the production and processing of guardrails, including a processing table 1, a support block 2 fixedly connected to the upper side of the processing table 1, a first electric push cylinder 3 fixedly connected to the support block 2, a protective cover 5 fixedly connected to the output end of the first electric push cylinder 3, an observation port 6 opened on the front side of the protective cover 5, a protective glass 7 fixedly connected to the inner wall of the observation port 6, a protective film that can be attached to the outer side of the protective glass 7 to reduce the glare of the fire light, a cutting component 8 provided on the upper side of the inner wall of the protective cover 5, and hidden grooves 9 opened on both sides of the protective cover 5, and a shrinking mechanism 10 provided on the inner wall of the hidden grooves 9.

[0025] The upper side of the processing table 1 has two sliding grooves 11, and the inner walls of the two sliding grooves 11 are slidably fitted with sliders 12. The adjacent sides of the two sliders 12 are fixedly connected with scrapers 13 that are in contact with the processing table 1. A linkage mechanism 14 is provided between the protective cover 5 and the two sliders 12. A storage mechanism 15 is provided on the lower side of the processing table 1. A feeding port 16 is provided on the upper side of the processing table 1. Fixing mechanisms 17 are provided on both sides of the protective cover 5.

[0026] Please see Figure 3The cutting assembly 8 includes a second electric push cylinder 801 fixedly connected to the upper side of the inner wall of the protective cover 5, an assembly plate 802 fixedly connected to the output end of the second electric push cylinder 801, a drive motor 803 fixedly connected to one side of the inner wall of the assembly plate 802, and a cutting disc 804 fixedly connected to the output end of the drive motor 803. The second electric push cylinder 801 pushes the assembly plate 802 to move, so that the drive motor 803 and the cutting disc 804 move synchronously, thereby processing the workpiece inside the protective cover 5 and limiting the sparks generated by the workpiece.

[0027] Please see Figure 3 The shrinkage mechanism 10 includes a shrinkage groove 101 formed on the upper side of the inner wall of the hidden groove 9, a spring 102 fixedly connected to the inner wall of the two shrinkage grooves 101, and two hidden plates 103 fixedly connected to the lower end of the spring 102 and slidingly engaged with the two shrinkage grooves 101. When the workpiece is placed, the hidden plates 103 contact the upper side of the workpiece, so that the compression spring 102 moves in the shrinkage groove 101. On the one hand, it can achieve temporary fixation, and on the other hand, it will not restrict the processing of the workpiece.

[0028] Please see Figure 1 The linkage mechanism 14 includes an inclined L-block 141 fixedly connected to two sliders 12, a guide opening 142 opened on one side of the inclined L-block 141, an extension plate 143 fixedly connected to both sides of the protective cover 5, and a guide rod 144 set on the opposite side of the extension plate 143 and cooperating with the guide opening 142. When the protective cover 5 moves upward, the guide rod 144 moves accordingly and moves within the guide opening 142. The lower side of the guide opening 142 is straight and the upper side is inclined. When moving in a straight line, the protective cover 5 will not affect the scraper 13. When it retracts upward to the inclined position, it will push the inclined L-block 141 to move, thereby driving the sliders 12 and the scraper 13 to move accordingly, and removing the debris on the upper side of the processing table 1.

[0029] Please see Figure 1 and Figure 4 The storage mechanism 15 includes two sliding blocks 151 fixedly connected to the lower side of the processing table 1, a sliding plate 152 slidably engaged with the two sliding blocks 151 on the same side, and a collection drawer 153 fixedly connected to the two sliding plates 152 on the same side. The collection drawer 153 is fixed by inserting the fixed collection drawer 153 and the sliding plate 152 into the sliding blocks 151. The collection drawer 153 is located below the discharge port 16 and is used for temporary storage of debris for subsequent unified processing.

[0030] Please see Figure 2The fixing mechanism 17 includes an extension plate 171 fixedly connected to both sides of the protective cover 5, a third electric push cylinder 172 fixedly connected to the lower side of the two extension plates 171, a fixing plate 173 fixedly connected to the output end of the third electric push cylinder 172, and an anti-slip pad 174 fixedly connected to the lower side of the fixing plate 173. After the protective cover 5 is fixed, the third electric push cylinder 172 is activated to press the fixing plate 173 and the anti-slip pad 174 downwards, thereby tightening and fixing the guardrail material on the upper side of the processing table 1.

[0031] Please see Figure 1 The lower side of the processing table 1 is fixedly connected with multiple support legs 18, and the upper side of the protective cover 5 is fixedly connected with a limiting rod 19 that slides with the support block 2. The processing table 1 is supported by the support legs 18. When the protective cover 5 moves up and down, the limiting rod 19 slides on the support block 2 accordingly, improving the stability of the movement.

[0032] The implementation principle of this application is as follows: In use, the guardrail material is first placed on the upper side of the processing table 1. Then, the first electric push cylinder 3 is activated to press down the protective cover 5. When the protective cover 5 is pressed down, its hidden plate 103 will be squeezed against the guardrail material. Under the action of the spring 102, the hidden plate 103 is squeezed in the shrinkage groove 101 and moves upward inside the shrinkage groove 101. Then, the third electric push cylinder 172 on the expansion plate 171 pushes the fixing plate 173 and the anti-slip pad 174 to move downward, respectively pressing down and fixing the guardrail material.

[0033] Then, by starting the drive motor 803, the cutting disc 804 is driven to rotate at high speed. The assembly plate 802 is gradually moved downward by the second electric push cylinder 801, so that the cutting disc 804 comes into contact with the raw material to achieve cutting. During the cutting process, the protective cover 5 can protect against sparks generated, and the protective glass 7 inside the observation port 6 can be used to reduce the light, protect eyesight, and prevent debris from flying and injuring people during the cutting process, thereby improving the safety of processing.

[0034] After processing is completed, the first electric push cylinder 3 is reset upwards, and personnel remove the cut guardrail material for further processing. Then, the first electric push cylinder 3 drives the protective cover 5 to move upwards. During the upward movement of the protective cover 5, the extension plate 143 and the guide rod 144 will move accordingly. When the guide rod 144 moves to the inclined position inside the guide port 142, the guide rod 144 will guide the guide port 142, thereby synchronously pushing the slider 12 and the scraper 13 to move. Since the scraper 13 is in contact with the upper side of the processing table 1, the scraper 13 can push the residual debris on the upper side of the processing table 1 to fall into the collection drawer 153 from the discharge port 16 for subsequent collection. This achieves unified collection of debris and reduces the manpower required for subsequent cleaning.
