Description

Technical Field

[0001] This invention relates to the field of sheet metal trimming technology, and particularly to a two-position coarse and fine trimming mechanism. Background Technology

[0002] Most traditional edge trimming mechanisms on the market consist of roughing and finishing mechanisms. Their basic principle is to use the mutual compression of the sheet metal, edge banding, and template to move the cutting tool, adjusting the position of the edge banding and the cutting tool. A motor then drives the cutting tool to trim the top and bottom edges of the edge banding. Disadvantages: ① Lack of gear adjustment, making it inconvenient to adjust the processing position when dealing with edge banding of different thicknesses, leading to decreased processing accuracy. ② Low adaptability, with separate roughing and finishing mechanisms requiring two separate mechanisms to complete the trimming work, resulting in low integration and excessive size. ③ High debugging and maintenance costs, as the separation of roughing and finishing mechanisms requires debugging two mechanisms, leading to high initial debugging costs and complex troubleshooting later.

[0020] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0021] Reference Figures 1 to 12 The two-position roughing and finishing mechanism of the present invention is implemented in the following embodiments: The two-position coarse and fine trimming mechanism includes a support base 100 and two sets of trimming units 200. The support base 100 has two vertically extending support rods 110. The two sets of trimming units 200 are arranged in opposite directions on the two support rods 110, and are used to trim the upper and lower sides of the board respectively. Each set of trimming units 200 includes a coarse and fine trimming blade assembly 210 and a coarse and fine trimming adjustment assembly 220. The coarse and fine trimming blade assembly 210 includes a coarse and fine trimming blade head 211 and a blade head drive unit 212. The blade head drive unit 212 is used to drive the coarse and fine trimming blade head 211 to rotate, and the blade head drive unit 212 is generally a blade head drive motor.

[0022] To enable the two-position roughing and finishing mechanism to perform both roughing and finishing functions, a roughing and finishing cutter head 211 is designed. The roughing and finishing cutter head 211 has a finishing cutter face 2115 and a finishing cutter face 2115. The roughing and finishing adjustment component 220 is used to drive the roughing and finishing cutter assembly 210 to move along the axial direction of the cutter body 2111. In this embodiment, the movement is horizontal, so that either the roughing cutter face 2114 or the finishing cutter face 2115 is positioned at the machining position. (Refer to...) Figure 11 and Figure 12When the finishing cutter face 2115 is in the machining position, the edge banding is finished; when the roughing cutter face 2114 is in the machining position, the edge banding is roughed. By moving the positions of the roughing and finishing cutter heads 211, the edge banding can be finished on both the upper and lower sides respectively. The same processing device can perform both roughing and finishing functions simultaneously. This device improves the adaptability of the edge trimming mechanism, making it more suitable for various customized needs. At the same time, the mechanism structure is more compact, reducing the cost of later maintenance and debugging.

[0023] Specifically, refer to Figures 8 to 10 The roughing and finishing cutter head 211 includes a cutter body 2111, with a fixing hole 2112 in the middle of the cutter body 2111. The fixing hole 2112 is connected to the output shaft of the cutter head drive unit 212. Six cutter holders 2113 are arranged obliquely at intervals around the outer periphery of the cutter body 2111. The cutter holders 2113 are provided with machining steps. The machining steps have two intersecting first step surfaces and second step surfaces. The first step surface is a roughing cutter surface 2114 that extends coaxially with the fixing hole 2112. The angle between the second step surface and the first step surface is greater than 90 degrees. The transition surface where the first step surface and the second step surface intersect is an arc-shaped curved surface. The arc-shaped curved surface is the finishing cutter surface 2115. The multiple roughing cutter surfaces 2114 are all located on the outline of a concentric circle with the center of the circle where the cutter body 2111 is located. The roughing cutter surfaces 2114 are curved surfaces on this outline. The structure of the roughing and finishing cutter head 211 allows for the horizontal movement of the roughing cutter face 2114 and the finishing cutter face 2115 to change their positions, thereby achieving the function of fine or rough finishing on the upper and lower sides of the edge banding.

[0024] To further improve the edge-removing effect, a first chip-removing groove 2116 is provided between the outer peripheral wall of the tool body 2111 and the tool holder 2113, and a second chip-removing groove 2117 is provided on the tool holder 2113. The first chip-removing groove 2116 and the second chip-removing groove 2117 are spaced apart. The first chip-removing groove 2116 and the second chip-removing groove 2117 provide physical space and guiding surfaces, allowing chips to be thrown out or carried out of the cutting area along the direction of the groove. This avoids machining interruptions, tool jamming, or even equipment damage caused by chip clogging.

[0025] Further improvements, refer to Figure 5 and Figure 7 It is also equipped with a first elastic reset member 223 to provide elastic force to ensure that the template can move backward while having enough pressure to stick to the plate and the edge banding, ensuring the correct relative position of the rough and fine trimming cutter head 211 and the plate. Then, the rough and fine trimming cutter head 211 is used to cut the edge banding to achieve the function of fine or rough trimming of the upper and lower sides of the edge banding.

[0026] The trimming unit 200 also includes a vertical slide 230, which slides up and down on two support rods 110. The coarse and fine trimming adjustment assembly 220 includes a horizontal slide 221, a first adjustment drive unit 222, and a first elastic reset member 223. The coarse and fine trimming blade assembly 210 is disposed on the horizontal slide 221, which has two guide shafts extending horizontally. The vertical slide 230 has mounting holes that slide with the guide shafts. The horizontal slide 221 is horizontally slidably disposed on the vertical slide 230 via the guide shafts. In some other embodiments, the horizontal slide 221 can be horizontally slidably disposed on the vertical slide 230 via guide rails.

[0027] Specifically, the horizontal slide table 221 is provided with a vertical plate 2212, and the vertical slide table 230 is provided with a baffle 231. The vertical plate 2212 and the baffle 231 are spaced apart. The first adjustment drive unit 222 is provided on the vertical plate 2212. The output end of the first adjustment drive unit 222 abuts against the baffle 231. The first elastic reset member 223 includes a reset screw 2231 provided on the baffle 231 and a reset spring 2232 sleeved on the reset screw 2231. The reset screw 2231 slides through the vertical plate 2212, and the reset spring 2232 abuts against the end step of the adjustment screw and the vertical plate 2212 respectively. The first adjustment drive unit 222 is equipped with a piston rod that can push the baffle 231 to move. When in the roughing position, the piston rod of the first adjustment drive unit 222 extends, causing the horizontal slide 221 to move horizontally to the right until the roughing cutter face 2114 is in the processing position, at which time the roughing cutter face 2114 contacts the edge banding tape. When in the finishing position, the piston rod of the first adjustment drive unit 222 retracts, and the first elastic reset member 223 provides a first elastic force to push the horizontal slide 221 to reset and move, so that the finishing cutter face 2115 is in the processing position, at which time the finishing cutter face 2115 contacts the edge banding tape. The first adjustment drive unit 222 can be a cylinder, and the first elastic reset member 223 is a first elastic reset spring 2232.

[0028] This embodiment uses a cylinder, a first adjustment drive unit 222, and a first elastic return spring 2232 to drive the position movement of the coarse and fine trimming head 211, completing two-position adjustment. In some other embodiments, the first adjustment drive unit 222 can also be used for driving. In this embodiment, the first adjustment drive unit 222 only needs to perform unidirectional action. The reset is completely handled by the first elastic return element 223 driving the position movement of the coarse and fine trimming head 211 to complete the two-position adjustment. The combination scheme in this embodiment saves one control direction, simplifies the air and electrical circuits, and reduces costs. Moreover, the first elastic return spring 2232 provides 100% reliable mechanical automatic reset. Regardless of whether it is powered or pneumatic, as soon as the cylinder is unloaded, the mechanism will definitely return to the preset initial position under the action of the spring. In addition, during high-speed trimming, the sheet metal may have slight vibrations. The flexibility of the first elastic return spring 2232 allows the template wheel to follow slightly and rebound quickly, maintaining contact. If it is a pure cylinder rigid connection, either the response will be slow and contact will be lost, or vibration will be caused by rigid impact.

[0029] To ensure better machining results, the stroke of the roughing and finishing cutter head 211 is adjustable. For details, please refer to... Figure 5 The vertical plate 2212 is adjustable with a first adjusting screw 225 and a second adjusting screw 226, both extending laterally. The first adjusting screw 225 passes through a baffle 231, and its end has a first stop block that abuts against the left side of the baffle 231. The end of the second adjusting screw 226 is located on the right side of the baffle 231, with the baffle 231 positioned between the ends of the first stop block and the second adjusting screw 226. By adjusting the interval between the ends of the first stop block and the second adjusting screw 226, the stroke of the roughing and finishing cutter head 211 can be adjusted, specifically according to actual needs.

[0030] Further improvements include an arc-shaped groove 2211 on the horizontal slide 221, and a roughing and finishing tool assembly 210 including a mounting base 224. The mounting base 224 is adjustablely fixed to the horizontal slide 221 along the arc-shaped groove 2211 by fixing screws. The tool head drive unit 212 is fixed to the horizontal slide 221. The angle of the tool finishing assembly can be adjusted.

[0031] In a further improvement, the mounting base 224 is provided with a first template assembly 240 and a second template assembly 250. The first template assembly 240 includes a first template 241, and the second template assembly 250 includes a second template 251. The first template 241 is located on the end face of the roughing and finishing cutter head 211 away from the horizontal slide table 221, and the second template 251 is located on the inclined side of the roughing and finishing cutter head 211. The first template 241 and the second template 251 form a clamping gap. The first template assembly 240 is provided with a height adjustment member for adjusting the height position of the first template 241.

[0032] In a further improvement, the second template assembly 250 also includes a template base 252 and a second adjustment drive unit 253. The second template 251 is disposed on the template base 252, and the template base 252 is slidably disposed on the mounting base 224 in the horizontal direction. The second adjustment drive unit 253 is used to drive the template base 252 to move in order to adjust the position of the second template 251. Specifically, the mounting base 224 is provided with a first limiting plate 2241 and a second limiting plate 2242 spaced apart to the left and right. The template base 252 is provided with a connecting plate 2521 that moves between the first limiting plate 2241 and the second limiting plate 2242. The second adjustment drive unit 253 is located on the second limiting plate 2242 and is connected to the connecting plate 2521. The connecting plate 2521 is adjustable with a third adjusting screw 2522, which abuts against the first limiting plate 2241. The second limiting plate 2242 is provided with a fourth adjusting screw 2523, which abuts against the connecting plate 2521. By rotating the fourth adjusting screw 2523 and the third adjusting screw 2522, the stroke of the connecting plate 2521 is limited. That is, by adjusting the stroke of the template base 252, it can accommodate edge banding tapes of different thicknesses. This arrangement, combined with stroke adjustment and the drive arrangement of the second adjustment drive unit 253, has a compact technical effect. The second adjustment drive unit 253 uses a cylinder.

[0033] Further improvements include a fifth adjusting screw 233 slidably mounted on the upper side of the upper vertical slide 230, and a first adjusting spring 235 mounted on the lower side of the lower vertical slide 230. An mounting sleeve is provided between the fifth adjusting screw 233 and the sliding hole of the vertical slide 230. Limiting steps are provided at both ends of the fifth adjusting screw 233. Two second adjusting springs 236 are mounted on the fifth adjusting screw 233, with both ends of the second adjusting springs abutting against the mounting sleeve and the limiting steps. A sixth adjusting screw 234 is connected to the first adjusting spring 235. The sixth adjusting screw 234 is adjustable vertically to the support base 100. The fifth adjusting screw 233, the sixth adjusting screw 234, the first adjusting spring 235, and the second adjusting spring 236 together provide a vertical preload to the vertical slide 230, enabling the two-position roughing and finishing mechanism to apply stable extrusion pressure to the sheet metal and edge banding. Furthermore, the relative position and extrusion pressure of the two trimming units 200 can be adjusted by adjusting the elastic force of the sixth adjusting screw 234 and the second adjusting spring 236. This application also provides a control method for a two-position roughing and finishing mechanism, the control method including the following steps: The first adjustment drive unit 222 extends the piston rod, and the roughing and finishing cutter head 211 moves along the axial direction of the cutter body 2111 so that the roughing cutter face 2114 is in the machining position for roughing. The first adjustment drive unit 222 is driven to retract the piston rod, and the roughing and finishing cutter head 211 moves along the axial direction of the cutter body 2111 so that the finishing cutter face 2115 is in the machining position for fine machining.

[0034] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
