Description

Technical Field

[0001] This application relates to the field of wear-resistant strip cutting, and in particular to tooling and equipment for cutting the length of wear-resistant strips. Background Technology

[0002] Wear-resistant strips are extruded from ultra-high molecular weight plastic materials and are used in products or fields such as conveyor belts, automated equipment, and conveyor guardrails. They have the characteristics of scratch resistance, aging resistance, high and low temperature resistance, and friction resistance. Their structure depends on the application.

[0003] To meet usage requirements, wear-resistant strips need to be cut into specified shapes and lengths before use. However, when cutting wear-resistant strips, the operator typically holds the strip by hand, measures and marks the dimensions with a ruler, and then cuts it with a tool. This entire process poses safety hazards and is also labor-intensive, resulting in poor cut surface quality and low precision. Utility Model Content

[0004] Therefore, it is necessary to provide a tooling device for cutting the length of wear-resistant strips.

[0052] This application discloses a wear-resistant strip length cutting fixture, which includes some or all of the technical features of the following embodiments; that is, the wear-resistant strip length cutting fixture includes some or all of the following structures. In one embodiment of this application, a wear-resistant strip length cutting fixture includes a wear-resistant strip clamping assembly and a wear-resistant strip cutting assembly; the wear-resistant strip clamping assembly includes a wear-resistant strip fixture base plate, a wear-resistant strip limiting structure, and a wear-resistant strip guide rail; the wear-resistant strip guide rail and the wear-resistant strip cutting assembly are disposed on the wear-resistant strip fixture base plate, the wear-resistant strip guide rail is used to load the wear-resistant strip to be processed and guide and adjust the position of the wear-resistant strip; the wear-resistant strip limiting structure is used to limit the wear-resistant strip on the wear-resistant strip guide rail; the wear-resistant strip cutting assembly is located above the wear-resistant strip guide rail and is used to cut the wear-resistant strip that is limited on the wear-resistant strip guide rail. The aforementioned wear-resistant strip length cutting fixture, through the cooperation of the wear-resistant strip clamping component and the wear-resistant strip cutting component, ensures that the wear-resistant strip is pressed by the wear-resistant strip limiting structure during the cutting process to enhance clamping stability. During non-cutting operations, the wear-resistant strip is not subjected to clamping force, allowing operators to easily and conveniently load and unload the wear-resistant strip. Furthermore, the cooperation between the wear-resistant strip guide rail and the wear-resistant strip limiting structure ensures that the wear-resistant strip does not bend or deform when clamped, and the wear-resistant strip can be loaded onto the wear-resistant strip guide rail for position adjustment, thus improving cutting accuracy and efficiency, and guaranteeing cutting results. The following section will further elaborate on this. Figures 1 to 8 The tooling equipment for cutting the length of the wear-resistant strip is described in detail.

[0053] In some embodiments, a wear-resistant strip length cutting fixture 100, such as... Figure 1 and Figure 2As shown, it includes a wear-resistant strip clamping assembly 200 and a wear-resistant strip cutting assembly 300; as an example, combined with Figure 6 and Figure 7 The wear-resistant strip clamping assembly 200 is used to clamp the wear-resistant strip 400 so that the wear-resistant strip 400 is in a clamped state when being cut; the wear-resistant strip cutting assembly 300 is used to cut the wear-resistant strip 400 clamped on the wear-resistant strip clamping assembly 200. Figure 3 and Figure 4 The wear-resistant strip clamping assembly 200 includes a wear-resistant strip fixture base plate 210, a wear-resistant strip limiting structure, and a wear-resistant strip guide rail 270. The wear-resistant strip guide rail 270 and the wear-resistant strip cutting assembly 300 are disposed on the wear-resistant strip fixture base plate 210. The wear-resistant strip guide rail 270 is used to load the wear-resistant strip 400 to be processed and to guide and adjust the position of the wear-resistant strip 400. The wear-resistant strip limiting structure is used to limit the wear-resistant strip 400 on the wear-resistant strip guide rail 270. The wear-resistant strip cutting assembly 300 is located above the wear-resistant strip guide rail 270 and is used to cut the wear-resistant strip 400 that is limited on the wear-resistant strip guide rail 270. This structural design, through the cooperation of the wear-resistant strip clamping assembly 200 and the wear-resistant strip cutting assembly 300, ensures that the wear-resistant strip 400 is pressed by the wear-resistant strip limiting structure during the cutting process to enhance clamping stability. In non-cutting processes, the wear-resistant strip 400 is not subjected to clamping force, allowing operators to easily and conveniently load and unload the wear-resistant strip 400. Furthermore, the cooperation between the wear-resistant strip guide rail 270 and the wear-resistant strip limiting structure ensures that the wear-resistant strip 400 does not bend or deform when clamped, and the wear-resistant strip 400 can be mounted on the wear-resistant strip guide rail 270 to adjust its position. Therefore, it is beneficial to improve cutting accuracy and efficiency, and ensure the cutting effect.

[0054] In each embodiment, the wear-resistant strip clamping assembly 200 includes a wear-resistant strip tooling base plate 210, a wear-resistant strip limiting structure, and a wear-resistant strip guide rail 270; the wear-resistant strip guide rail 270 and the wear-resistant strip cutting assembly 300 are disposed on the wear-resistant strip tooling base plate 210. As an example, the wear-resistant strip tooling base plate 210 can be disposed on a machine base, machine frame, or workbench. The wear-resistant strip guide rail 270 is used to load the wear-resistant strip 400 to be processed, that is, to load the wear-resistant strip 400 to be cut onto the wear-resistant strip guide rail 270; and the wear-resistant strip guide rail 270 is also used to guide and adjust the position of the wear-resistant strip 400, so that the wear-resistant strip 400 loaded on the wear-resistant strip guide rail 270 can move, for example, slide along the wear-resistant strip guide rail 270, thereby adjusting the position of the wear-resistant strip 400 relative to the wear-resistant strip guide rail 270, that is, adjusting the position of the wear-resistant strip 400 relative to the wear-resistant strip tooling base plate 210, so as to accurately perform the cutting operation.

[0055] As an example, the wear-resistant strip guide rail 270 is a continuous guide rail. Exemplarily, the shape of the wear-resistant strip guide rail 270 is adapted to the wear-resistant strip 400, that is, the wear-resistant strip guide rail 270 is a contour-following track. In other embodiments, the wear-resistant strip guide rail 270 may also be a discontinuous multi-segment guide rail. In some embodiments, such as Figure 3 and Figure 4 As shown, the wear-resistant strip guide rail 270 includes a first wear-resistant strip guide rail 271, a second wear-resistant strip guide rail 272, a third wear-resistant strip guide rail 273, and a fourth wear-resistant strip guide rail 274 arranged sequentially. The first wear-resistant strip guide rail 271, the second wear-resistant strip guide rail 272, the third wear-resistant strip guide rail 273, and the fourth wear-resistant strip guide rail 274 have the same guiding direction, that is, the first wear-resistant strip guide rail 271, the second wear-resistant strip guide rail 272, the third wear-resistant strip guide rail 273, and the fourth wear-resistant strip guide rail 274 extend in the same direction. They are used to jointly load the wear-resistant strip 400 to be processed and to jointly guide and adjust the position of the wear-resistant strip 400. The wear-resistant strip cutting component 300 is located between the second wear-resistant strip guide rail 272 and the third wear-resistant strip guide rail 273, or the wear-resistant strip cutting component 300 is located above the second wear-resistant strip guide rail 272 or the third wear-resistant strip guide rail 273. As an example, the shapes of the first wear-resistant strip guide rail 271, the second wear-resistant strip guide rail 272, the third wear-resistant strip guide rail 273, and the fourth wear-resistant strip guide rail 274 are adapted to the wear-resistant strip 400, that is, the first wear-resistant strip guide rail 271, the second wear-resistant strip guide rail 272, the third wear-resistant strip guide rail 273, and the fourth wear-resistant strip guide rail 274 are all contour-following rails. Figure 8 As shown, in some embodiments, the wear-resistant strip guide rail 270, or the first wear-resistant strip guide rail 271 and the second wear-resistant strip guide rail 272 of the wear-resistant strip guide rail 270, is provided with a length marking position 290. This structural design facilitates the rapid assembly of the wear-resistant strip 400 to be processed onto the wear-resistant strip guide rail 270 and makes it easy to adjust the position of the wear-resistant strip 400 on the wear-resistant strip guide rail 270. Furthermore, in conjunction with embodiments having length marking positions 290, the length position of the wear-resistant strip 400 to be processed can be conveniently and accurately marked, enabling rapid completion of the cutting operation. Therefore, it helps to improve cutting accuracy and efficiency, and ensures the cutting effect.

[0056] In various embodiments, the wear-resistant strip limiting structure is used to limit the wear-resistant strip 400 on the wear-resistant strip guide rail 270; in some embodiments, such as Figure 4 and Figure 6As shown, the wear-resistant strip limiting structure includes a wear-resistant strip limiting block 230 and a limiting side plate 240; the bottom of the wear-resistant strip guide rail 270 is disposed on the wear-resistant strip tooling base plate 210; the limiting side plate 240 is disposed on the wear-resistant strip tooling base plate 210, combined with... Figure 7 The limiting side plate 240 and the wear-resistant strip guide rail 270 have a gap 241, which is used to limit the displacement of the wear-resistant strip 400 from the side of the wear-resistant strip guide rail 270; the wear-resistant strip limiting block 230 is detachably disposed on the wear-resistant strip guide rail 270, which is used to limit the displacement limit position of the wear-resistant strip 400 relative to the wear-resistant strip guide rail 270. This structural design further facilitates the rapid assembly of the wear-resistant strip 400 to be processed onto the wear-resistant strip guide rail 270, and makes it easy to adjust the position of the wear-resistant strip 400 on the wear-resistant strip guide rail 270. During the cutting operation, the wear-resistant strip 400 is pressed by the wear-resistant strip limiting structure to enhance clamping stability. In non-cutting processes, the wear-resistant strip 400 is not subjected to clamping force, and the operator can easily and conveniently complete the loading and unloading of the wear-resistant strip 400.

[0057] In some of these embodiments, such as Figure 4 As shown, the wear-resistant strip clamping assembly 200 also includes a wear-resistant strip length adjustment bracket 250 and a length adjustment screw 260. The wear-resistant strip length adjustment bracket 250 is disposed on the wear-resistant strip fixture base plate 210, and abuts against the wear-resistant strip guide rail 270 via the length adjustment screw 260. When the wear-resistant strip guide rail 270 is loosely connected to the wear-resistant strip fixture base plate 210, the length adjustment screw 260 adjusts the position of the wear-resistant strip guide rail 270 on the wear-resistant strip fixture base plate 210, and then the wear-resistant strip guide rail 270 is fastened to the wear-resistant strip fixture base plate 210. This structural design facilitates fine-tuning of the position of the wear-resistant strip guide rail 270 on the wear-resistant strip fixture base plate 210, allowing for more accurate adjustment of the position of the wear-resistant strip 400 on the wear-resistant strip guide rail 270. This improves cutting accuracy and efficiency, and ensures the best possible cutting effect.

[0058] In some of these embodiments, such as Figure 8 As shown, the wear-resistant strip clamping assembly 200 also includes a positioning and fitting assembly 280, and the wear-resistant strip limiting block 230 is detachably mounted on the wear-resistant strip guide rail 270 through the positioning and fitting assembly 280. Figure 8In the illustrated embodiment, the wear-resistant strip limiting block 230 is a pin-hole mating structure. This structural design can quickly and effectively limit the wear-resistant strip 400 to be processed to enhance clamping stability. The effect is even better when combined with the embodiment with the length marking position 290, which can accurately achieve the positioning and clamping of the wear-resistant strip 400, and ensure that the wear-resistant strip 400 does not bend or deform when clamped. Therefore, it is further beneficial to improve cutting accuracy and cutting efficiency, and ensure the cutting effect as much as possible.

[0059] In various embodiments, the wear-resistant strip cutting assembly 300 is located above the wear-resistant strip guide rail 270 and is used to cut the wear-resistant strip 400 that is confined on the wear-resistant strip guide rail 270. In some embodiments, such as Figure 3 and Figure 4 As shown, the wear-resistant strip clamping assembly 200 also includes a polyurethane pressure block 220. The polyurethane pressure block 220 is disposed on the second wear-resistant strip guide rail 272 of the wear-resistant strip guide rail 270. The polyurethane pressure block 220 is used to abut against the wear-resistant strip cutting assembly 300 when the wear-resistant strip cutting die 360 ​​is cutting the wear-resistant strip 400, so as to limit the deepest cutting position of the wear-resistant strip cutting die 360. Or in combination Figure 5 The polyurethane pressure block 220 is used to abut against the die fixing frame 350 of the wear-resistant strip cutting assembly 300 when the wear-resistant strip cutting die 360 ​​is cutting the wear-resistant strip 400, thereby limiting the deepest cutting position of the wear-resistant strip cutting die 360. With this structural design, when the wear-resistant strip cutting die 360 ​​of the wear-resistant strip cutting assembly 300 is cutting the wear-resistant strip 400, the polyurethane pressure block 220 of appropriate height, in conjunction with the wear-resistant strip clamping block 380 of the wear-resistant strip cutting assembly 300, can limit the deepest cutting position of the wear-resistant strip cutting die 360. That is, in the moving direction of the wear-resistant strip cutting die 360, the maximum moving distance of the wear-resistant strip cutting die 360 ​​is limited, avoiding over-cutting that would cause the wear-resistant strip cutting die 360 ​​to cut onto the wear-resistant strip tooling base plate 210, thereby protecting both the wear-resistant strip cutting die 360 ​​and the wear-resistant strip tooling base plate 210.

[0060] In some of these embodiments, such as Figure 5As shown, the wear-resistant strip cutting assembly 300 includes a linear track 303, a reset assembly, a tool holder mounting platform 310, an operating assembly, a die holder fixing frame 350, and a wear-resistant strip cutting die 360. The tool holder mounting platform 310 is disposed on the wear-resistant strip tooling base plate 210. The linear track 303 and the operating assembly are disposed on the tool holder mounting platform 310. The die holder fixing frame 350 is slidably disposed on the linear track 303 and is connected to the tool holder mounting platform 310 through the reset assembly. The operating assembly is connected to the die holder fixing frame 350 and is used to move the die holder fixing frame 350 along the track under stress. The linear track 303 slides downwards, causing the die holder 350 to move towards the wear-resistant strip 400 that is limited on the wear-resistant strip guide rail 270, i.e., causing the die holder 350 to approach the wear-resistant strip 400 that is limited on the wear-resistant strip guide rail 270; the reset component is used to allow the die holder 350 to slide upwards on the linear track 303 when the operating component is in a non-forced state; the wear-resistant strip cutting die 360 ​​is disposed below the die holder 350 and above the wear-resistant strip guide rail 270, and is used to cut the wear-resistant strip 400 under the action of the operating component. Figure 3 and Figure 5 The wear-resistant strip cutting assembly 300 has a slot 351 under the die holder 350 to allow the wear-resistant strip 400 to pass through the slot 351, so that the wear-resistant strip cutting die 360 ​​can cut the wear-resistant strip 400 from above. This structural design allows the die holder 350 to be quickly and effectively controlled to slide along the linear track 303 via the operating components. It is suitable for both manual operation by operators and automatic operation by robots or robotic arms. With the reset component, after the cutting operation is completed and the external force disappears, the die holder 350 drives the wear-resistant strip cutting die 360 ​​to slide along the linear track 303 to reset, facilitating the next cutting operation.

[0061] In some of these embodiments, such as Figure 5As shown, the wear-resistant strip cutting assembly 300 also includes a spring guide shaft 370 and a wear-resistant strip clamping block 380. The wear-resistant strip clamping block 380 is disposed under the die holder 350 via the spring guide shaft 370, and is used to elastically press the wear-resistant strip 400 under the action of the operating assembly for cutting by the wear-resistant strip cutting die 360. This structural design is beneficial in two ways: firstly, it helps to press the wear-resistant strip 400 tightly when the wear-resistant strip cutting die 360 ​​is cutting the wear-resistant strip 400, so as to avoid the wear-resistant strip 400 from moving and affecting the cutting effect, or even causing poor cutting. Secondly, it is beneficial to cooperate with the embodiment with the polyurethane pressure block 220 to limit the maximum cutting position of the wear-resistant strip cutting die 360, so as to protect the wear-resistant strip cutting die 360 ​​and the wear-resistant strip guide rail 270.

[0062] In some of these embodiments, such as Figure 5 As shown, the reset assembly includes a lower reset hook 304, a reset tension spring 305, and an upper reset hook 306. The lower reset hook 304 is connected to the die holder 350, and the upper reset hook 306 is connected to the die holder mounting platform 310. The upper reset hook 306 is connected to the lower reset hook 304 via the reset tension spring 305. This structural design, through the cooperation of the lower reset hook 304, the reset tension spring 305, and the upper reset hook 306, ensures that after the cutting operation is completed and the external force disappears, the reset tension spring 305 drives the die holder 350 to reset via the lower reset hook 304. The die holder 350 then drives the wear-resistant cutting die 360 ​​to slide along the linear track 303 to achieve reset, facilitating accurate cutting operations in the next operation.

[0063] As an example, the operating component includes a tension-type operating structure, a rotation-type operating structure, a sliding operating structure, and a pressure-type operating structure. In some embodiments, such as Figure 5As shown, the operating components include a first hinge pin 301, a second hinge pin 302, a hinge support 320, a pressure rod 330, and a connecting rod 340. The pressure rod 330 is connected to the hinge support 320 via the first hinge pin 301. The hinge support 320 is mounted on the tool holder mounting platform 310. The pressure rod 330 is also connected to the connecting rod 340 via the second hinge pin 302. The connecting rod 340 is connected to the die holder 350 and is used to allow the die holder 350 to slide downward along the linear track 303 when the pressure rod 330 is under pressure. This structural design, through the cooperation of the first hinge pin 301, the second hinge pin 302, the hinge support 320, the pressure rod 330, and the connecting rod 340, realizes the downward pressure operation control. Only manual or automated equipment needs to apply downward pressure to the pressure rod 330, which will drive the die holder 350 to move downward in the direction shown in the figure through the connecting rod 340. The die holder 350 drives the wear-resistant strip cutting die 360 ​​to slide along the linear track 303 to realize the cutting operation.

[0064] The following will continue to combine Figures 1 to 8 The wear-resistant strip length cutting fixture 100 is illustrated in some embodiments. In some embodiments, the wear-resistant strip length cutting fixture 100 can be applied to the field of fully automated sample processing systems to cut ultra-high molecular weight polyethylene wear-resistant strips with specific structures. In other embodiments, the wear-resistant strip length cutting fixture 100 can also cut wear-resistant strips made of other materials such as PC or PMMA.

[0065] The first wear-resistant strip guide rail 271, the second wear-resistant strip guide rail 272, the third wear-resistant strip guide rail 273, and the fourth wear-resistant strip guide rail 274 in the wear-resistant strip clamping assembly 200 are all designed to conform to the shape and structure of the cut wear-resistant strip 400. During clamping, the wear-resistant strip 400 is moved along the track direction while being pressed against the conforming mating surface. During the process, the limiting side plate 240 corrects the straightness of the wear-resistant strip 400 to prevent length deviation caused by bending of the wear-resistant strip 400. Figure 7 As shown. Once the wear-resistant strip is blocked by the wear-resistant strip limiting block 230, the length limitation is completed, as shown. Figure 6 As shown. If different lengths of limiting are required, simply align the wear-resistant strip limiting block 230 with the pins next to the corresponding length markings on the third wear-resistant strip guide rail 273 and the fourth wear-resistant strip guide rail 274, and place them accordingly. Figure 8 As shown.

[0066] The wear-resistant strip cutting assembly 300 is primarily responsible for completing the cutting action of the wear-resistant strip. The hinged support 320, pressure rod 330, connecting rod 340, and die holder 350 are hinged together by a first hinge pin 301 and a second hinge pin 302. The die holder 350 is connected to the die holder mounting platform 310 via a linear track 303, and the hinged support 320 is fixed to the die holder mounting platform 310. For example, when the operator presses the pressure rod 330, the force on the pressure rod 330 is transmitted to the die holder 350 via the connecting rod 340, causing a downward cutting motion. Before the wear-resistant strip cutting die 360 ​​cuts into the wear-resistant strip 400, the wear-resistant strip clamping block 380 contacts and clamps the wear-resistant strip 400 to prevent it from shifting. The clamping force is provided by a spring passing through the spring guide shaft 370. When the wear-resistant strip 400 is cut, due to the lever arm relationship formed by the connecting rod 340 hinged on the pressure rod 330 and the position of the hand pressing, the arm force of the person will be amplified several times and then transmitted to the wear-resistant strip cutting die 360 ​​for cutting. In this way, the operator can easily complete the cutting with one hand. After the cutting is completed and the hand is released, the reset tension spring 305 pulls the cutting-related motion components back to the initial position through the reset hook 304 to facilitate the removal of the wear-resistant strip 400 and the clamping of the next strip.

[0067] If the length of the cut wear-resistant strip deviates from the expected value, the length adjusting screw 260 on the wear-resistant strip length adjusting bracket 250 can be adjusted after loosening the fixing screws at the waist-shaped holes on the third wear-resistant strip guide rail 273 and the fourth wear-resistant strip guide rail 274 to achieve fine adjustment of the limit length, thereby ensuring processing accuracy. If the structure of the wear-resistant strip changes, the contouring structure of the first wear-resistant strip guide rail 271, the second wear-resistant strip guide rail 272, the third wear-resistant strip guide rail 273, and the wear-resistant strip guide rail 4 should be modified accordingly to ensure that the wear-resistant strip can be placed and clamped stably; if the angle of the cutting surface needs to be adjusted, the bending angle of the wear-resistant strip cutting die 360 ​​and the angle of the limiting surface on the wear-resistant strip limiting block 230 can be changed, such as Figure 7 and Figure 8 As shown.

[0068] This structural design, combined with the contour track and clamping design, ensures stable clamping of the wear-resistant strip 400 while guaranteeing convenient loading and unloading, preventing the wear-resistant strip 400 from shifting during cutting. The quickly movable wear-resistant strip limiting block 230 supports various cutting lengths. The hinged support 320, pressure rod 330, and connecting rod 340 work together to form a labor-saving cutting mechanism that allows operators to complete the cutting action with one hand, while ensuring accuracy and the flatness of the cut surface.

[0069] It should be noted that other embodiments of this application also include wear-resistant strip length cutting fixtures formed by combining the technical features of the above embodiments.

[0070] The technical features of the above embodiments can be combined in any way.

[0071] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
