Description

Technical Field

[0001] The utility model relates to the technical field of cutting machine protection, in particular to a cutting machine protection device. Background Art

[0002] The cutting machine is a kind of mechanical equipment widely used in various industrial fields. It is mainly used for cutting, cutting, deburring and other operations on metal materials such as steel bars and round steel. Its working principle is to efficiently process metal materials through cutting tools. It is easy to operate and highly efficient.

[0003] However, in current cutting machine applications, open cutting and fully enclosed cutting are two main working modes, but both have significant disadvantages.

[0004] The main problem with the open cutting method is that it cannot ensure that the spatter will not burn the operator. Especially when cutting hard materials such as metal and plastic, the spatter is often generated at a very fast speed and high temperature. If the operator is too close to the cutting point or the protective measures are not in place, the spatter is likely to cause burns or other injuries to the operator.

[0005] Although the fully enclosed cutting method solves the problem of splashing and injuring people to a certain extent, it also brings new challenges. Since the entire cutting process is enclosed inside the machine, the operator cannot observe the cutting situation in real time. This may make it difficult for the operator to find abnormal conditions during the cutting process, such as incomplete cutting of the material, offset cutting position, etc., thus affecting the cutting quality and efficiency. Utility Model Content

[0006] The main purpose of the utility model is to provide a protective device for a cutting machine, which can effectively solve the problems raised in the background technology.

A debris collection box is connected between the two fixing seats. Plug rods are provided at both ends of the debris collection box, and the debris collection box is installed on the protective cover through the plug rods. The debris collection box is used to collect some cutting splashes.

[0012] In a further preferred solution, a hydraulic cylinder is installed on the support table. A plurality of limit holes are provided at the lower end of the reciprocating workbench. The telescopic end of the hydraulic cylinder is inserted into one of the limit holes to fix the reciprocating workbench.

[0013] In a further preferred solution, the plurality of limit holes are equidistantly distributed. The inner wall of the limit hole is designed to be smooth, the telescopic end of the hydraulic cylinder is designed to be smooth, and the hydraulic cylinder is fixed to the support table by bolts.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0026] like Figure 1 - Figure 5 As shown, this embodiment provides a protective device for a cutting machine, which is intended to improve the safety and cleanliness of the cutting operation. The device mainly includes core components such as a support table 1, an adjustment bracket 3, a servo motor 4, a cutting disc 5 and a positioning fixture 6.

[0027] The support table 1 serves as the basis of the entire device, and an adjustment bracket 3 is installed on its upper side wall for supporting and adjusting the position of a servo motor 4. The servo motor 4 is installed on the adjustment bracket 3 and connected to the cutting disc 5. By controlling the operation of the servo motor 4, the cutting disc 5 can be driven to perform a cutting operation.

[0028] On the support table 1, two parallel slide bars 9 are installed through a bracket, and sliders 10 are installed on the two slide bars 9. A reciprocating workbench 2 is installed on the upper end of the slider 10, and a positioning fixture 6 is provided on the upper end of the workbench for clamping the object to be cut. By pushing the reciprocating workbench 2 to move on the slide bars 9, the object to be cut clamped on the positioning fixture 6 can be driven to move, thereby adjusting its cutting length.

[0029] To improve safety during the operation process, a protective cover 11 is installed on the upper edge of the reciprocating workbench 2. Inside the protective cover 11, a double-layer transparent cover 12 is connected. Through the double-layer transparent cover 12, the operator can clearly observe the cutting process. At the same time, the double-layer transparent cover 12 can also effectively block the flying objects generated during the cutting process, protecting the safety of the operator.

[0030] In addition, two symmetrical fixing seats 14 are installed at the lower part of the inner wall of the protective cover 11. A debris collection box 13 is connected between these two fixing seats 14. The two ends of the debris collection box 13 are provided with insertion rods 15, and these insertion rods 15 can be inserted into the insertion holes of the fixing seats 14, thereby firmly installing the debris collection box 13 on the protective cover 11. During the cutting operation process, the debris collection box 13 can collect some cutting flying objects and keep the working environment clean.

[0031] The cross-section of the protective cover 11 is designed in an inverted '丿' shape. Such a design can not only provide enough protection space but also not obstruct the operator's line of sight. The protective cover 11 is fixed on the reciprocating workbench 2 by bolts, while the double-layer transparent cover 12 is clamped on the protective cover 11 through a card slot or other means, and a colloid is coated at the connection between the two to enhance the sealing performance and stability.

[0032] The fixing seat 14 and the protective cover 11 are integrally designed, improving the overall structural strength and stability. The fixing seat 14 is provided with insertion holes adapted to the insertion rods 15, and the insertion rods 15 and the debris collection box 13 are fixedly connected by welding or other means to ensure the stability of the debris collection box 13 during use. Embodiment

[0033] This embodiment is further improved on the basis of Embodiment 1 to improve the practicability and convenience of the device.

[0034] As Figure 1 - Figure 3 shown, the same as Embodiment 1, the protective device for the cutting machine in this embodiment also includes core components such as a support table 1, an adjustment bracket 3, a servo motor 4, a cutting disc 5, and a positioning fixture 6. The structures and functions of these components are the same as those described in Embodiment 1, so they will not be elaborated here.

[0035] On the support table 1, two parallel slide rods 9 are also installed through brackets. The slider 10 moves on the slide rods 9, driving the reciprocating workbench 2 and the positioning fixture 6 thereon to perform reciprocating motion. Such a design enables the operator to adjust the cutting length of the item to be cut as needed.

[0036] In order to improve the working efficiency and convenience, the present embodiment installs a hydraulic cylinder 7 on the support table 1. The telescopic end of the hydraulic cylinder 7 can be inserted into the limit hole 8 at the lower end of the reciprocating worktable 2, thereby fixing the position of the reciprocating worktable 2. This design allows the operator to conveniently fix the reciprocating worktable 2 when adjusting the cutting length or performing other operations, thereby avoiding the inconvenience caused by its movement.

[0037] A plurality of limiting holes 8 are evenly distributed at the lower end of the reciprocating worktable 2, and the telescopic end of the hydraulic cylinder 7 can be inserted into different limiting holes 8 as needed to achieve fixation at different positions. The hole wall of the limiting hole 8 and the telescopic end of the hydraulic cylinder 7 are both designed to be smooth surfaces to reduce friction and wear and increase service life.

[0038] In addition, the hydraulic cylinder 7 is fixed to the support table 1 by bolts to ensure its stability and reliability. This design makes it difficult for the hydraulic cylinder 7 to loosen or shift during use, thereby ensuring the stability and safety of the entire device.

[0039] Through the improved design of this embodiment, the protective device for the cutting machine further improves the practicality and convenience while maintaining the original function, so that the operator can complete the cutting operation more conveniently and efficiently during use.

[0040] Working process: The operator controls the extension and retraction of the hydraulic cylinder 7 according to the needs of the object to be cut, so that the extension end of the hydraulic cylinder 7 is inserted into a certain limiting hole 8 at the lower end of the reciprocating worktable 2. Since the limiting holes 8 are equidistantly distributed at the lower end of the reciprocating worktable 2, the operator can select different limiting holes 8 for insertion according to actual needs, thereby fixing the reciprocating worktable 2 on the support table 1.

[0041] When the telescopic end of the hydraulic cylinder 7 is inserted into the limiting hole 8, the position of the reciprocating table 2 will be firmly fixed due to the stability and reliability of the hydraulic cylinder 7 and will not move due to external factors. This fixing method is simple and efficient, and improves the stability and safety of the cutting operation.

[0042] Next, the operator can start the servo motor 4 to drive the cutting disc 5 to perform the cutting operation. Since the reciprocating workbench 2 has been fixed, the object to be cut held by the positioning fixture 6 will remain in a stable position, which is convenient for the cutting disc 5 to perform accurate cutting.

[0043] During the cutting operation, if the cutting length of the object to be cut needs to be adjusted, the operator can first stop the operation of the servo motor 4, and then control the extension and retraction of the hydraulic cylinder 7 to pull the extension end out of the current limiting hole 8 and insert it into another limiting hole 8, thereby changing the position of the reciprocating workbench 2 on the support table 1. This adjustment process is fast and convenient, and improves the working efficiency.

[0044] Finally, when the cutting operation is completed, the operator can control the telescopic end of the hydraulic cylinder 7 to fully retract and release the fixation of the reciprocating workbench 2. Then, the operator can push the reciprocating workbench 2 to move on the slide bar 9, take out the cut objects, and prepare for the next round of cutting operation.

[0045] During the working process of the reciprocating table 2 supported by the hydraulic cylinder 7, the operator can conveniently fix and adjust the position of the reciprocating table 2, thereby achieving accurate and efficient cutting operations. At the same time, the stability and reliability of the hydraulic cylinder 7 also ensure the safety and stability of the entire operation process.

[0046] The present invention is not limited to the above-mentioned embodiments. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
