Technical Field

[0001] This utility model relates to the technical field of bending equipment, and in particular to a bending pressure knife locking mechanism and a knife-jointing device. Background Technology

[0002] Bending centers can bend metal sheets at various angles using simple molds, resulting in complex shapes. During processing, the sheet is typically pressed down by a pressure cutter, and then bent by a rear bending device. Furthermore, the pressure cutter needs to be adjusted according to the specific bending requirements to accommodate different bending ranges. Currently, manual adjustment methods use bolt-locked pressure plates to lock and unlock the pressure cutter, which is cumbersome, prone to stripping threads, reduces equipment reliability, and affects adjustment efficiency.

The first direction is set at an angle to the cutting direction. The actuator has an actuating part that is inclined along a second direction. The second direction is set at an angle to the first direction. The two ends of the actuating part along the second direction are spaced apart in the first direction. The actuating part is used to slide and abut against one end of the locking pin. The locking drive assembly is used to drive the actuator to move relative to the pressing body along the second direction, so that the other end of the locking pin presses against or releases the cutting tool holder.

[0005] The beneficial effects of the bending and pressing knife locking mechanism of this utility model are: During the knife-jointing process, the locking drive assembly moves the actuator to one end in the second direction, controlling the locking pin to loosen the knife holder, allowing the pressing body to be adjusted along the knife-jointing direction. Once adjusted to the set position, the locking drive assembly moves the actuator to the other end in the second direction, causing the actuating part to push the locking pin to move along the first direction, pressing the locking pin against the knife holder and locking the pressing body onto the knife holder. This invention uses the locking drive assembly to move the actuator, and the inclined actuating part to transmit force to the locking pin, thereby achieving the loosening and locking of the pressing body. It is easy to operate and improves the adjustment efficiency of knife-jointing.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0022] Reference Figures 1-5 The present invention provides a knife-jointing device in the following embodiment: like Figure 1 and Figure 2 As shown, the blade assembly device in this embodiment includes the bending and pressing blade locking mechanism, wherein the bending and pressing blade locking mechanism includes a blade holder 100, a pressing blade body 200, and a locking structure 300.

[0023] The tool holder 100 extends in a left-right direction, and multiple pressure bodies 200 are provided. These multiple pressure bodies 200 are arranged sequentially on the tool holder 100 along the blade assembly direction. In this embodiment, the blade assembly direction is defined as left-right. The pressure bodies 200 are slidably connected to the tool holder 100 in the left-right direction. Figure 3 As shown, each pressure body 200 is provided with a locking structure 300, which is used to lock and release the sliding of the pressure body 200.

[0024] like Figure 4 and Figure 5As shown, the locking structure 300 of this embodiment includes a locking pin 310, an actuating element 320, and a locking drive assembly 330. The locking pin 310 extends along a first direction and is slidably mounted on the pressing body 200. In this embodiment, the first direction is defined as the front-rear direction. In some other embodiments, the first direction can be other directions, as long as the first direction forms an angle with the cutting direction. Therefore, in this embodiment, the locking pin 310 extends along the front-rear direction and is slidably mounted on the pressing body 200 along the front-rear direction.

[0025] In this embodiment, the actuator 320 is provided with an actuating part 321 that is inclined along a second direction. In this embodiment, the second direction is defined as the up-down direction. In some other embodiments, the second direction can be other directions, as long as the second direction and the first direction are at an angle. Therefore, in this embodiment, the actuating part 321 is inclined along the up-down direction, and the upper and lower ends of the actuating part 321 are spaced apart in the front-back direction. In this embodiment, the actuating part 321 is used to slide and abut against one end of the locking pin 310. In this embodiment, the front end of the locking pin 310 slides and abuts against the actuating part 321.

[0026] The locking drive assembly 330 is used to move the actuator 320 relative to the pressure body 200 in the vertical direction, so that the rear end of the locking pin 310 presses against the tool holder 100 or releases the tool holder 100.

[0027] During the blade assembly process, the locking drive assembly 330 drives the actuator 320 to move one end in the up-down direction, thereby controlling the locking pin 310 to release the blade holder 100. This allows the pressure body 200 to slide and adjust in the left-right direction. Once adjusted to the set position, the locking drive assembly 330 drives the actuator 320 to move the other end in the up-down direction, causing the actuator 321 to push the locking pin 310 backward. This pushes the locking pin 310 to press against the blade holder 100, locking the pressure body 200 onto the blade holder 100.

[0028] This invention uses a locking drive assembly 330 to move an actuator 320, and transmits force to a locking pin 310 through an inclined actuating part 321, thereby releasing and locking the pressure knife body 200. This makes operation convenient and improves the adjustment efficiency of the knife assembly.

[0029] like Figure 3 , Figure 4 and Figure 5As shown, the locking drive assembly 330 of this utility model includes a gear 331, a rotating handle 332 for driving the gear 331 to rotate, and an actuator 320 is provided with a toothed portion 322 extending in the vertical direction. The gear 331 meshes with the toothed portion 322. In this embodiment, the gear 331 is driven to rotate by rotating the rotating handle 332. Under the meshing of the gear 331 and the toothed portion 322, the actuator 320 is driven to move back and forth in the vertical direction. Compared with the traditional locking method, the operator can simply rotate the rotating handle 332, which is simple to operate and does not require tightening the bolt.

[0030] Furthermore, such as Figure 3 and Figure 4 As shown, the locking drive assembly 330 of this embodiment also includes a mounting base 333 that is detachably mounted on the pressure body 200. The gear 331 is rotatably mounted on the mounting base 333, and the actuator 320 is slidably mounted on the mounting base 333 in the up-down direction. It can be understood that the locking drive assembly 330 of this embodiment is modularly mounted and can be manufactured independently of the pressure body 200 for easy assembly.

[0031] like Figure 3 and Figure 4 As shown, in this embodiment, the gear 331 is coaxially fixedly connected to the connecting shaft 334. Rotary bearings 335 are respectively installed at both ends of the connecting shaft 334. The rotary bearings 335 are fixedly installed on the mounting base 333. The rotating handle 332 is connected to both ends of the connecting shaft 334. In this embodiment, the rotating handle 332 has a "U" shaped structure.

[0032] In this embodiment, the gear 331 is arranged axially perpendicular to the vertical direction. Specifically, in this embodiment, the connecting shaft 334 extends in the horizontal direction. When the handle 332 is rotated downwards, the actuating part 321 pushes the locking pin 310 to abut against the tool holder 100. Figure 3 and 5 As shown, when the handle 332 swings downward, it drives the gear 331 to rotate counterclockwise, driving the actuator 320 to move upward. In this embodiment, the actuator 321 is tilted backward from top to bottom. At this time, the actuator 321 pushes the locking pin 310 to move backward, so that the locking pin 310 presses against the tool holder 100. In this way, under the gravity of the handle 332, it remains at the lower limit of the swing, which has a self-locking effect on the gear 331, preventing the gear 331 from rotating and causing the locking pin 310 to loosen. When the handle 332 swings upward, it drives the gear 331 to rotate clockwise, driving the actuator 320 to move downward. At this time, the actuator 321 separates from the locking pin 310, so that the locking pin 310 can move freely forward to loosen from the tool holder 100.

[0033] like Figure 5As shown, the pressure body 200 of this embodiment is provided with a guide hole 210 extending through in the front-back direction, and the locking pin 310 is slidably disposed in the guide hole 210.

[0034] like Figure 5 As shown, the front end of the locking pin 310 is provided with a limiting shoulder 311. The limiting shoulder 311 is used to abut against the end face of the guide hole 210 to limit the backward movement of the locking pin 310. The backward movement of the locking pin 310 is limited by the actuator 320.

[0035] like Figure 5 As shown, the bottom of the knife holder 100 in this embodiment is provided with a dovetail slide rail 110 extending in the left and right direction. The side of the dovetail slide rail 110 is provided with a downwardly inclined dovetail slope 111. The rear end of the locking pin 310 is provided with an inclined abutment end face 312. The abutment end face 312 matches and abuts with the dovetail slope 111, which can achieve the effect of pre-tightening and pressing to improve the stability of locking.

[0036] like Figure 5 As shown, the actuating part 321 in this embodiment has an inclined structure. The actuating part 321 slides and abuts against the front end of the locking pin 310. When the locking pin 310 locks the pressing body 200, the actuating part 321 abuts against the front end of the locking pin 310. When the locking pin 310 releases the pressing body 200, the actuating part 321 separates from the front end of the locking pin 310. At this time, the locking pin 310 can move freely in the front-back direction to release the pressing body 200.

[0037] In some other embodiments, the actuating part 321 may be an inclined guide rail structure, which locks the front end of the locking pin 310 in a sliding fit, and can drive the locking pin 310 to move forward and backward.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
