Description

Technical Field

[0001] This invention relates to the field of bending machine technology, and in particular to a pressure knife mounting structure, pressure knife assembly, and method of use that are easy to disassemble and assemble. Background Technology

[0002] Currently, the pressure cutters on bending machines need to be combined and adjusted according to actual processing requirements. Existing equipment generally uses a side-sliding-in / sliding-out method for pressure cutter assembly and disassembly. If it is necessary to replace the pressure cutter located in the middle, all the side pressure cutters must be removed before operation can be performed. In addition, when assembling the pressure cutter, the operator needs to lift the pressure cutter and align it with the end of the mounting slide rail before pushing it in from the side. For larger and heavier pressure cutters, this operation is not only laborious but also prone to slippage. Furthermore, the locking method for the pressure cutter is cumbersome. Summary of the Invention The purpose of this invention is to provide a pressure knife mounting structure, pressure knife assembly and usage method that are easy to disassemble and assemble, so as to solve one or more technical problems existing in the prior art, or at least provide a beneficial option or create conditions.

[0003] The technical solution adopted to solve the above-mentioned technical problems is as follows: This invention provides a pressure knife mounting structure that is easy to assemble and disassemble, comprising: The tool holder is provided with a first sliding engagement part and a locking part that extend in the left and right directions; The pressure knife is provided with a second sliding engagement part for engaging with the first sliding engagement part in the front-rear direction and a locking mechanism for locking with the locking part; When the second sliding engagement part and the first sliding engagement part engage with each other in the front-back direction, a lock is formed between them, thereby restricting the relative displacement of the pressure knife and the knife holder in the vertical direction. When the two parts separate in the front-back direction, the restriction between the pressure knife and the knife holder in the vertical direction is released. When the locking mechanism engages with the locking part, the relative position between the pressure knife and the knife holder is locked in the front-back direction and the left-right direction.

[0004] The beneficial effects of the pressure knife mounting structure of the present invention are: When installing the pressure knife, the present invention first aligns the pressure knife with the knife holder in the front-to-back direction, so that the second sliding locking part engages with the first sliding locking part to limit the relative displacement of the pressure knife and the knife holder in the vertical direction. Then, the locking mechanism and the locking part are engaged to lock the relative position of the pressure knife and the knife holder in the front-to-back and horizontal directions. When it is necessary to disassemble the pressure knife, the engagement between the locking mechanism and the locking part is first released, and then the pressure knife is moved off the knife holder in the front-to-back direction, so that the second sliding locking part and the first sliding locking part separate in the front-to-back direction. The present invention allows the pressure knife to be disassembled and assembled separately in the front-to-back direction, which is convenient to operate.

[0005] As a further improvement to the above technical solution, the first sliding engagement portion includes a first sliding engagement strip and a first sliding engagement groove that both extend in the left-right direction. The first sliding engagement strip and the first sliding engagement groove are arranged facing forward. The second sliding engagement portion includes a second sliding engagement groove and a second sliding engagement strip that both are arranged facing backward. The second sliding engagement groove and the first sliding engagement strip engage with each other in the front-back direction. The second sliding engagement strip and the first sliding engagement groove engage with each other in the front-back direction.

[0006] As a further improvement to the above technical solution, the first sliding locking strip protrudes forward on the front side of the tool holder, the first sliding locking groove is open forward on the rear part of the bottom side of the tool holder, the second sliding locking groove is open rearward on the front part of the top side of the pressure knife, and the second sliding locking strip protrudes rearward on the top of the rear side of the pressure knife.

[0007] As a further improvement to the above technical solution, the locking mechanism includes a top pin disposed on the top side of the pressure knife, an adjustment component that drives the top pin to move up and down, and the locking part is a locking groove recessed on the bottom side of the knife holder, wherein the upper end of the top pin is locked and engaged with the locking groove.

[0008] As a further improvement to the above technical solution, the pressure knife is provided with a pin hole extending vertically, and the top pin is slidably disposed in the pin hole.

[0009] As a further improvement to the above technical solution, the front side of the pressure knife is provided with an adjustment hole, the adjustment hole is connected to the pin hole, the adjustment assembly includes a rotating shaft rotatably installed in the adjustment hole, the rear end of the rotating shaft is eccentrically provided with an adjustment block, the side wall of the top pin is provided with a slot that fits with the adjustment block, and the inner diameter of the slot is larger than the outer diameter of the adjustment block.

[0010] As a further improvement to the above technical solution, the adjusting component also includes an elastic element disposed in the pin hole. The elastic element acts between the top pin and the pin hole, and the elastic element is used to provide an upward elastic force to the top pin.

[0011] As a further improvement to the above technical solution, the front sidewall of the locking groove is inclined from bottom to top and backward. The top of the top pin is provided with a locking slope that matches and abuts against the front sidewall of the locking groove. When the top pin extends upward into the locking groove, the locking slope slides against the front sidewall of the locking groove, causing the pressure knife to shift backward relative to the knife holder, so that the second sliding locking groove is tightly engaged with the first sliding locking strip, and the second sliding locking strip is tightly engaged with the first sliding locking groove.

[0012] The present invention proposes a pressing knife assembly, including the pressing knife mounting structure, wherein multiple pressing knives are provided and the multiple pressing knives are arranged and mounted on the knife holder in a left-right direction.

[0013] The present invention also proposes a method of using the pressing assembly, applicable to the pressing assembly, the method of using the assembly comprising: When installing the pressure knife, first align the pressure knife with the knife holder in the front-back direction, so that the second sliding locking part engages with the first sliding locking part to limit the relative displacement of the pressure knife and the knife holder in the vertical direction. Then, control the locking mechanism to cooperate with the locking part to lock, thereby locking the relative position of the pressure knife and the knife holder in the front-back and left-right directions. When it is necessary to disassemble the pressure knife, first release the locking mechanism from the locking part, and then move the pressure knife out of the knife holder in the front-back direction, so that the second sliding locking part and the first sliding locking part separate from each other in the front-back direction.

[0020] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of the present invention, not all embodiments.

[0021] Reference Figures 1-6 The easy-to-assemble and disassemble pressure knife mounting structure of the present invention is illustrated in the following embodiments: like Figure 1 As shown, the pressure knife mounting structure of the present invention includes: a knife holder 100 and a pressure knife 200.

[0022] The tool holder 100 extends to the left and right, and is provided with a first sliding engagement part and a locking part, both of which extend in the left and right direction.

[0023] like Figure 2 As shown, the pressure knife 200 is provided with a second sliding engagement part and a locking mechanism 300. The second sliding engagement part is used to engage with the first sliding engagement part in the front-back direction. When the second sliding engagement part and the first sliding engagement part engage with each other in the front-back direction, a lock is formed between them, thereby restricting the relative displacement of the pressure knife 200 and the tool holder 100 in the vertical direction. When the two separate in the front-back direction, the restriction between the pressure knife 200 and the tool holder 100 in the vertical direction is released.

[0024] The locking mechanism 300 of the present invention is used to lock with the locking part. When the locking mechanism 300 locks with the locking part, it locks the relative position between the pressure knife 200 and the knife holder 100 in the front-back direction and the left-right direction.

[0025] When installing the pressure knife 200, the present invention first aligns the pressure knife 200 with the knife holder 100 in the front-back direction, so that the second sliding engagement part engages with the first sliding engagement part to limit the relative displacement of the pressure knife 200 and the knife holder 100 in the vertical direction. Then, the locking mechanism 300 is controlled to cooperate with the locking part to lock, thereby locking the relative position of the pressure knife 200 and the knife holder 100 in the front-back and left-right directions, so as to achieve spatial fixation of the pressure knife 200 relative to the knife holder 100.

[0026] When it is necessary to disassemble the pressure knife 200, first release the locking mechanism 300 from the locking part, and then move the pressure knife 200 out of the knife holder 100 in the front-back direction, so that the second sliding locking part and the first sliding locking part separate from each other in the front-back direction.

[0027] The present invention allows the pressure knife 200 to be disassembled and assembled separately from the front and rear directions, without the need to disassemble and assemble from the left and right ends, making it convenient to operate.

[0028] Among them, such as Figures 1 to 3As shown, the first sliding engagement portion of this embodiment includes a first sliding engagement strip 110 and a first sliding engagement groove 120. Both the first sliding engagement strip 110 and the first sliding engagement groove 120 extend in the left-right direction and are both facing forward. The second sliding engagement portion of this embodiment includes a second sliding engagement groove 210 and a second sliding engagement strip 220. Both the second sliding engagement groove 210 and the second sliding engagement strip 220 are facing backward. The second sliding engagement groove 210 and the first sliding engagement strip 110 engage with each other in the front-back direction. The locking strip 220 and the first sliding locking groove 120 engage with each other in the front-to-back direction. It can be understood that when the pressure knife 200 is installed on the tool holder 100, the second sliding locking groove 210 and the second sliding locking strip 220 are respectively positioned opposite the first sliding locking strip 110 and the first sliding locking groove 120 in the front-to-back direction. Then, the pressure knife 200 is moved backward, so that the second sliding locking groove 210 and the first sliding locking strip 110, and the second sliding locking strip 220 and the first sliding locking groove 120 engage with each other, thereby improving the firmness of the connection between the pressure knife 200 and the tool holder 100.

[0029] Furthermore, such as Figure 2 As shown, in this embodiment, the first sliding locking strip 110 protrudes forward on the front side of the tool holder 100, and the first sliding locking groove 120 is open forward and located at the rear of the bottom side of the tool holder 100. The first sliding locking strip 110 and the first sliding locking groove 120 are spaced apart in the front-back direction and also spaced apart in the up-down direction. The second sliding locking groove 210 is open rearward and located at the front of the top side of the pressure knife 200, and the second sliding locking strip 220 protrudes rearward on the top of the rear side of the pressure knife 200, so as to form two supporting positions between the pressure knife 200 and the tool holder 100.

[0030] And, as Figure 2 As shown, in this embodiment, the top surface of the pressure knife 200 abuts against the bottom surface of the knife holder 100. When the pressure knife 200 presses the plate, the bottom surface of the knife holder 100 provides a downward force to the pressure knife 200, thereby increasing the pressing force.

[0031] like Figure 4As shown, the locking mechanism 300 of this embodiment includes a top pin 310 disposed on the top side of the pressure knife 200 and an adjustment component that drives the top pin 310 to move up and down. The locking part is a locking groove 130 recessed on the bottom side of the knife holder 100. The upper end of the top pin 310 is locked and engaged with the locking groove 130. When the second sliding engagement groove 210 is engaged with the first sliding engagement strip 110 and the second sliding engagement strip 220 is engaged with the first sliding engagement groove 120, the locking groove 130 and the top pin 310 are arranged vertically opposite each other. At this time, the adjustment component drives the top pin 310 to move upward and extend into the locking groove 130 to lock the pressure knife 200 and the knife holder 100 in the front-back direction.

[0032] Specifically, such as Figure 3 and Figure 4 As shown, the pressing knife 200 in this embodiment has a vertically extending pin hole 230, and a top pin 310 is slidably disposed in the pin hole 230. An adjusting hole 240 is provided on the front side of the pressing knife 200, extending forward and backward, and communicating with the pin hole 230. The adjusting assembly includes a rotating shaft 320 rotatably mounted in the adjusting hole 240. Figure 4 and Figure 5 As shown, an adjusting block 321 is eccentrically provided at the rear end of the rotating shaft 320, as... Figure 4 and Figure 6 As shown, the side wall of the top pin 310 is provided with a slot 311 that fits with the adjusting block 321. The inner diameter of the slot 311 is larger than the outer diameter of the adjusting block 321. It can be understood that the present invention drives the adjusting block 321 to make eccentric movements by rotating the rotating shaft 320. At this time, the adjusting block 321 drives the top pin 310 to move up and down. By operating the front end of the rotating shaft 320 to drive the rotating shaft 320 to rotate, the unlocking control of the top pin 310 can be realized.

[0033] In this embodiment, the rotating shaft 320 has an inner corner hole at its front end to facilitate the rotation of the rotating shaft 320. Furthermore, the rotating shaft 320 has an annular limiting groove 322 on its outer periphery, and the adjusting hole 240 has a limiting block extending into the annular limiting groove 322 to limit the axial direction of the rotating shaft 320 without interfering with its rotation.

[0034] Furthermore, such as Figure 2 and Figure 4 As shown, the adjustment component of this embodiment also includes an elastic element 330 disposed in the pin hole 230. The elastic element 330 acts between the top pin 310 and the pin hole 230. The elastic element 330 is used to provide an upward elastic force to the top pin 310. In the natural state, the elastic element 330 always provides an upward elastic force to the top pin 310. When rotating the rotating shaft 320, the elastic force pushes the top pin 310 upward, thereby avoiding the phenomenon of the top pin 310 getting stuck.

[0035] In this embodiment, the elastic element 330 is a spring.

[0036] To improve the stability of the lock, such as Figure 4 As shown, the front sidewall of the locking groove 130 in this embodiment is inclined from bottom to top and rear. The top of the top pin 310 is provided with a locking slope 312 that matches and abuts against the front sidewall of the locking groove 130. When the top pin 310 extends upward into the locking groove 130, under the sliding contact between the locking slope 312 and the front sidewall of the locking groove 130, the pressure knife 200 is driven to shift backward relative to the knife holder 100, so that the second sliding snap groove 210 is tightly engaged with the first sliding snap strip 110 and the second sliding snap strip 220 is tightly engaged with the first sliding snap groove 120, so as to achieve a certain pre-tightening effect.

[0037] The present invention proposes a pressing knife assembly, including the pressing knife mounting structure described above, wherein multiple pressing knives 200 are provided, and the multiple pressing knives 200 are arranged and mounted on the knife holder 100 in the left-right direction.

[0038] This invention also proposes a method for using the pressure-gripping assembly, applicable to the aforementioned pressure-gripping assembly, such as... Figure 7 As shown, the method of using the present invention includes: Step S100: When installing the pressure knife 200, first align the pressure knife 200 with the tool holder 100 in the front-back direction, so that the second sliding locking part and the first sliding locking part engage with each other to limit the relative displacement of the pressure knife 200 and the tool holder 100 in the vertical direction. Then, control the locking mechanism 300 to cooperate with the locking part to lock, thereby locking the relative position of the pressure knife 200 and the tool holder 100 in the front-back direction and the left-right direction. Step S200: When it is necessary to disassemble the pressure knife 200, first release the locking mechanism 300 from the locking part, and then move the pressure knife 200 out of the knife holder 100 in the front-back direction, so that the second sliding locking part and the first sliding locking part are separated from each other in the front-back direction.

[0039] In step S100, the second sliding engagement groove 210 and the second sliding engagement strip 220 are respectively positioned opposite to the first sliding engagement strip 110 and the first sliding engagement groove 120 in the front-back direction. Then, the pressure knife 200 is driven to move backward, so that the second sliding engagement groove 210 and the first sliding engagement strip 110, and the second sliding engagement strip 220 and the first sliding engagement groove 120 are engaged with each other. At this time, the locking groove 130 and the top pin 310 are positioned opposite each other vertically.

[0040] Then, the rotating shaft 320 is rotated, and under the elastic force of the elastic member 330, the top pin 310 is pushed upward. When the top pin 310 extends upward into the locking groove 130, the locking inclined surface 312 slides against the front side wall of the locking groove 130, causing the pressure knife 200 to shift backward relative to the knife holder 100, so that the second sliding locking groove 210 is tightly engaged with the first sliding locking strip 110, and the second sliding locking strip 220 is tightly engaged with the first sliding locking groove 120.

[0041] In step S200, the rotating shaft 320 is rotated to drive the adjusting block 321 to make eccentric movements. The adjusting block 321 drives the top pin 310 to move downward, controlling the top pin 310 to separate from the locking groove 130, and then the pressure knife 200 is pulled forward.
