Abstract

The invention belongs to the technical field of stainless steel machining and cutting, and particularly relates to a cutting device for stainless steel product machining. A stainless steel workpiece is placed at the upper end of the workbench, and the screw rod is controlled to rotate through rotation of the crank, so that the jacking plate continuously moves until the stainless steel workpiece is clamped between the jacking plate and the supporting block. The motor controls the second synchronous wheel to drive the first synchronous wheel and the cutting blade under connection of the synchronous belt. When the cutting blade rotates at a high speed, an operator controls the cutting blade to press a stainless steel workpiece downwards for cutting by holding the handle, in the process, the reset spring in the stirring connecting frame is pulled, and the cutting blade is immediately driven to move upwards and reset after the operator loosens the hand. After a set of stainless steel workpieces are cut, an operator rotates the cutting blade by 90 degrees to the other side by shifting the baffle, and in the process, the connecting frame is shifted to drive the middle shaft and the special-shaped wheel to rotate.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stainless steel processing cutting, in particular to a cutting device for stainless steel product processing. BACKGROUND

[0002] The mechanical cutting device used in stainless steel product processing mainly drives the cutting gear to rotate at high speed through the motor-driven synchronous belt transmission system. When the workpiece is accurately positioned by the clamp mechanism, the operator presses down the tool holder assembly provided with the high-speed rotating cutting gear to complete the cutting operation. The device uses a special-shaped wheel and a spring-loaded positioning mechanism to realize 90° indexing adjustment of the cutting angle. The whole system relies on precise mechanical linkage (including thread transmission, elastic return, phase locking mechanism, etc.) to ensure that the cutting accuracy is stable within ±0.5mm.

[0003] The prior art has the following disadvantages: Modern stainless steel cutting machines generally use high-speed rotating alloy blades as cutting tools, which are driven by mechanical power to cut stainless steel materials at a speed of thousands of revolutions per minute. In order to ensure cutting accuracy and prevent material displacement, the workpiece needs to be fixed by a clamping mechanism during operation. Common clamping methods include mechanical vices or pneumatic clamps. These devices form a three-sided enclosed structure with the cutting blade, thereby stabilizing the workpiece position. However, this design brings inconvenience to operation after cutting is completed: when the blade completes cutting and retracts slightly, the remaining vertical space is insufficient to accommodate the direct removal of larger workpieces. Therefore, the operator often needs to pull the workpiece out from the side horizontally, which not only increases the operation steps, but also has safety hazards due to the blade still being in the working area. In addition, since the blade does not completely exit the machining area, the equipment cannot immediately proceed to the next cutting operation, resulting in limited production efficiency. This design defect is particularly prominent in batch processing scenarios and needs to be improved through optimized mechanical structure or automation solutions. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a cutting device for stainless steel product processing, which solves the problem of the difficulty in quickly removing large stainless steel workpieces after cutting, which affects cutting efficiency.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: a cutting device for stainless steel product processing, comprising a workbench, a cutting blade, and a baffle for providing protection, the workbench is provided with a fixed base at the upper end, a middle shaft is rotatably arranged inside the fixed base, and the middle shaft serves as a support structure for the cutting blade when it works, so that the middle shaft can be rotated.

[0006] An irregular-shaped wheel is arranged outside the middle shaft.

[0007] Four sets of clamping blocks are arranged on the top of the fixed base.

[0008] In some embodiments, a first synchronous pulley is arranged on the side end of the cutting blade. A synchronous belt is sleeved outside the first synchronous pulley, and a second synchronous pulley is further arranged at the other end of the synchronous belt;

[0009] A motor for providing driving force is arranged on the side end of the second synchronous pulley, and the output end of the motor is connected to the second synchronous pulley.

[0010] In some embodiments, a dust-proof cover for preventing dust from falling into the transmission structure is sleeved outside the first synchronous pulley and the second synchronous pulley.

[0011] In some embodiments, a拨动连接架 (it should be a specific component name, please check and correct if there is an error in the original) is rotatably arranged at the bottom of the motor, and a reset spring for automatically moving the cutting blade for downward cutting upward to reset after losing the downward pressure is inserted at the connection;

[0012] The outside of the motor is connected to the side end of the baffle by bolts.

[0013] In some embodiments, a handle for facilitating an operator to press the cutting blade is inserted at the side end of the dust-proof cover. The handle is in a "匚" shape and extends to the other side after bypassing the side end of the baffle.

[0014] In some embodiments, the clamping blocks have the same shape, and a through groove with the same shape as the special-shaped wheel is formed in the middle after the clamping blocks are combined.

[0015] In some embodiments, the special-shaped wheel has a cross-symmetric structure, and there are four arc-shaped protruding parts on the outside.

[0016] In some embodiments, four sets of wing plates for providing lateral support are arranged on the side wall of the fixed base. A plug rod is arranged at the side end of the clamping block, and a spring is sleeved outside the plug rod. The spring is clamped between the wing plate and the outside of the clamping block;

[0017] A slide rail is arranged at the upper end of the fixed base. The slide rail is embedded at the bottom of the clamping block and is used to limit the moving stroke of the clamping block.

[0018] In some embodiments, a support block and a positioning block are further arranged at the upper end of the workbench. A screw rod is inserted through the middle of the positioning block, and a pressing plate is arranged at the end of the screw rod. The screw rod is used to adjust the position of the pressing plate;

[0019] A crank is sleeved at the other end of the screw rod to facilitate rotating the screw rod.

[0020] Compared with the prior art, the present invention provides a cutting device for stainless steel product processing, having the following beneficial effects:

[0021] A cutting device for processing stainless steel products involves placing the stainless steel workpiece on the upper part of a worktable and rotating a screw via a crank handle, causing a clamping plate to move continuously until the stainless steel workpiece is clamped between the clamping plate and a support block. A motor-controlled synchronous pulley 2, connected by a synchronous belt, drives synchronous pulley 1 and the cutting blade. While the cutting blade rotates at high speed, the operator holds the handle to control the blade to press down on the stainless steel workpiece for cutting. During this process, a return spring inside the connecting frame is pulled, and immediately after the operator releases their hand, the cutting blade moves upward to its original position. After a set of stainless steel workpieces is cut, the operator rotates the cutting blade 90° to the other side by moving a baffle plate. During this process, the connecting frame rotates, causing the central shaft and the shaped wheel to rotate. As the shaped wheel rotates inside the clamping block, it pushes against the clamping block, compressing the spring. After the shaped wheel completes its 90° rotation, the spring 18 rebounds, causing the clamping block to return to its original position, thus ensuring that the rotation angle of the cutting blade is fixed at 90°.

[0022] Through the aforementioned setup and process, this structure, compared to existing stainless steel product processing and cutting devices, effectively solves the space limitations of traditional stainless steel cutting devices by introducing a rotatable cutting module. Its core design lies in this: after the cutting process is completed, the drive mechanism controls the entire cutting structure (including the blade and supporting components) to rotate 90°-180° axially, causing the blade, originally perpendicular to the workpiece, to quickly deflect to a lateral or reverse position. This mechanical movement instantly frees up the operating space directly above the workpiece, allowing operators to directly and vertically remove the workpiece, completely avoiding the cumbersome process of horizontally removing the workpiece in traditional methods. More importantly, the rotated cutting structure is positioned in the standby area on the other side of the equipment, its spatial location completely offset from the new workpiece processing area. Therefore, the equipment can immediately start the next round of cutting operations, achieving true continuous production. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] Please see Figures 1-7In this embodiment: a cutting device for processing stainless steel products includes a worktable 1, a cutting blade 2, and a baffle 3 for providing protection. A fixed base 11 is provided on the upper end of the worktable 1, and a central shaft 14 is rotatably arranged inside the fixed base 11. When the central shaft 14 serves as a support structure for the cutting blade 2, it can rotate through the central shaft 14, thereby enabling the cutting blade 2 to be quickly moved away from the working area, clearing the area above the stainless steel workpiece, and achieving the purpose of quickly removing the workpiece.

[0035] To ensure stable cutting operation of the cutting blade 2, a timing pulley 4 is installed on the side of the cutting blade 2, and a timing belt 5 is fitted around the outside of the timing pulley 4. A timing pulley 6 is also installed at the other end of the timing belt 5. A motor 9, providing driving force, is installed on the side of the timing pulley 6, and the output of the motor 9 is connected to the timing pulley 6 (e.g., ...). Figure 3 As shown in the figure, the motor 9 can drive the cutting blade 2 to rotate through the synchronous pulley 6 and the synchronous pulley 4, and make it reach the cutting speed.

[0036] A dust cover 7 is fitted on the outside of synchronous pulley 4 and synchronous pulley 6 to prevent dust from falling into the transmission structure (e.g., ...). Figure 2 (As shown).

[0037] To enable the cutting blade 2 to complete the cutting action (a downward nodding cut), a toggle connecting bracket 10 is rotatably installed at the bottom of the motor 9. A return spring is also inserted at the connection point. The return spring is used to automatically move the cutting blade 2 back to its original position after the downward cutting pressure is released. The outer side of the motor 9 is bolted to the side of the baffle 3. A handle 8 is inserted into the side of the dust cover 7 to facilitate the operator pressing the cutting blade 2. The handle 8 is shaped like a "U" and extends to the other side after passing around the side of the baffle 3 (e.g., ...). Figure 3 (As shown). With the above settings, the cutting blade 2 only needs to apply pressure to the handle 8 to complete the downward cutting action and automatically reset.

[0038] Because cutting stainless steel workpieces requires high precision, it is essential to ensure that the cutting line of the cutting blade 2 remains aligned with the axis. Therefore, after the cutting blade 2 rotates, to ensure that the cutting line does not deviate beyond its range, a shaped wheel 15 (such as...) is fitted around the outer side of the central shaft 14. Figure 6 As shown), four sets of clamping blocks 16 are provided on the top of the fixed base 11. The clamping blocks 16 are identical in shape, and after the clamping blocks 16 are combined, a through groove with the same shape as the irregular wheel 15 is formed in the middle (as shown). Figure 6 As shown, since the top of the central shaft 14 is connected to the actuating connecting frame 10, the inner through groove of the clamp block 16 can limit the stroke of the actuating connecting frame 10 and the motor 9 above it by embedding the irregular wheel 15.

[0039] The irregularly shaped wheel 15 has a cross-shaped symmetrical structure, with four arc-shaped protrusions on the outer side (such as...). Figure 6 As shown), through its connection with the through groove in the middle of the clamping block 16, its specific structural changes during rotation are as follows:

[0040] When the irregular wheel 15 rotates, the four sets of protrusions on the outer side will abut against the inner side of the clamping block 16. At this time, the positions of the irregular wheel 15 and the central shaft 14 are not stable. Continue to rotate the central shaft 14 until the rotation angle reaches 90°. When the outer protrusion of the irregular wheel 15 is embedded into the other end of the inner through groove of the clamping block 16, the overall structure remains stable.

[0041] Since the outer protrusion of the irregular wheel 15 will abut against the clamping block 16, in order for the clamping block 16 to move within a small range while providing an outer limit for the irregular wheel 15, it needs to have a certain range of offset travel. Therefore:

[0042] Four sets of wing plates 13 are provided on the side wall of the fixed base 11 to provide lateral support. Insert rods 17 are provided on the side ends of the clamping block 16, and springs 18 are sleeved on the outside of the insert rods 17. The springs 18 are clamped between the wing plates 13 and the outside of the clamping block 16 (e.g., ...). Figure 6 As shown in the figure, this arrangement allows the clamping block 16 to push outwards and compress the spring 18 when it is squeezed by the rotating shaped wheel 15. After the shaped wheel 15 completes a 90° rotation, the spring 18 rebounds and causes the clamping block 16 to return to its original position, so that the clamping block 16 provides external clamping to the shaped wheel 15 in real time.

[0043] A slide rail 19 is provided on the upper end of the fixed base 11. The slide rail 19 is embedded in the bottom of the clamping block 16 and is used to limit the movement stroke of the clamping block 16.

[0044] To achieve stable stainless steel cutting, a cutting groove 21 is provided at the upper end of the worktable 1. The cutting groove 21 can accommodate the embedding of the cutting blade 2 and prevent blade collision. A support block 20 and a positioning block 25 are also provided at the upper end of the worktable 1. A screw 22 is inserted through the middle of the positioning block 25, and a clamping plate 23 is provided at the end of the screw 22. This allows the stainless steel workpiece to be clamped by the support block 20 and the clamping plate 23 for stable cutting, while the screw 22 is used to adjust the position of the clamping plate 23. A crank handle 24 is fitted on the other end of the screw 22 to facilitate the rotation of the screw 22.

[0045] After the stainless steel workpiece is placed on the upper part of the worktable 1, the operator drives the screw 22 to rotate by rotating the crank handle 24, causing the clamping plate 23 to move along the thread axis until the workpiece is stably clamped in the clamping area formed by the clamping plate 23 and the support block 20. When the motor 9 starts, it drives the synchronous belt 5 through the synchronous pulley 2 6, so that the synchronous pulley 1 4 drives the cutting blade 2 to the working speed. The operator holds the handle 8 and presses down on the cutting blade 2 to perform the cutting operation. At this time, the return spring inside the connecting frame 10 is stretched and stores elastic potential energy. After releasing the handle, the spring rebounds and drives the cutting blade 2 to quickly return to the initial height. After completing a single set of cuts, the baffle 3 is moved to rotate the cutting blade 2 by 90°. This action drives the irregular wheel 15 to rotate synchronously through the central shaft 14. The asymmetrical contour of the irregular wheel 15 presses the clamping block 16 to compress the spring 18. When it rotates to the 90° position, the spring 18 pushes the clamping block 16 to engage with the positioning groove of the irregular wheel 15, ensuring that the cutting blade 2 is accurately locked at the new working angle. Throughout the entire process, all moving parts follow a preset mechanical linkage relationship. The thread lead of screw 22, the transmission ratio of synchronous belt 5, the elastic coefficient of return spring, and the phase angle of shaped wheel 15 are all precisely calculated to ensure that the system's repeatability is within ±0.5mm.

[0046] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
