[0002] The anti-theft door leaf is usually made of metal plate, which is bent into the required shape by a folding machine and then welded to form the door leaf. The existing door leaf processing method first bends the two long sides and then the two short sides; and when bending the short sides, the pressure plate of the folding machine presses and bends the steel plate downward, and the steel plate of the door leaf bends upward. At this time, it is necessary to manually lift the other end of the steel plate upward with the help of the machine. Since the steel plate has a certain width, two workers are required to lift it up at the same time. This processing method is easy to cause the steel plate to deform due to different forces on both sides during the bending process of the machine, which affects the aesthetics at the least and cannot be installed at the worst.

[0025] Reference Figure 1-4 As shown, a new type of bending machine for door leaf processing includes a lower mold 1, a movable mold 2, a reset mold 3 and a bending machine (not shown), wherein the lower mold 1 is arranged on the workbench of the bending machine, and the movable mold 2 is connected to the downward pressing slide of the bending machine; the lower mold 1 is an "L"-shaped block, and the "L"-shaped block is provided with a mounting groove 11, and the mounting groove 11 is provided with a reset spring 12 at intervals, the reset module 3 is a "T"-shaped block, and the "T"-shaped block is inserted into the mounting groove 11, and the reset spring 12 is arranged between the lower mold 1 and the reset module 3; the movable mold 2 is a rectangular block, and the right-angle side of the "L"-shaped block of the rectangular block is provided with an avoidance groove 21.

[0026] Through the lower mold 1 of the horizontally set "L"-shaped block, the forming plate 4 is horizontally placed on the platform formed by the reset mold 3 and the lower mold 1, and the movable mold 2 is pressed down, and the right angle of the "L"-shaped block of the lower mold 1 works together to press the forming plate 4 down to form a 90° bend, and the forming plate 4 and the "T"-shaped block of the reset mold 3 are horizontally lowered together. During the forming process, no manual assistance is required to lift, which reduces the labor intensity of the staff. The entire bending process is completed by the equipment itself without manual intervention, avoiding the problem of door leaf deformation caused by uneven force on both sides, and improving the yield rate and product quality of the door leaf.

[0027] Furthermore, a waste trough 13 is provided at a right angle of the "L"-shaped block.

[0028] During the bending process, extrusion occurs between the movable mold 2 and the forming plate 4, the forming plate 4 and the lower mold 1, and the reset mold 3 and the lower mold 1, which easily forms debris, which is collected through the waste trough 13 to avoid accumulation at right angles, affecting the pressing down of the reset mold 3, causing the forming plate 4 to not be bent into place, and affecting product quality.

[0029] Furthermore, the avoidance groove 21 is trapezoidal.

[0030] The setting of the avoidance groove 21 allows the forming plate 4 to be bent twice at right angles to form a U-shaped bending groove, which is then bent to form two door leaf plates that are spliced ​​to each other. The door leaf plates are spliced ​​to each other to form a door leaf.

[0031] Furthermore, two ends of the resetting module 3 are provided with limit blocks 31 , and the limit blocks 31 are arranged opposite to the right-angled sides of the “L”-shaped block.

[0032] When the thickness of the forming plate 4 is large, the movable mold 2 will form a force away from the right angle side of the lower mold 1 during the downward pressing process, causing the bending angle to be greater than 90°; or multiple bendings are required to achieve the effect of right angle bending, which reduces work efficiency and easily causes damage to the bending machine equipment. By setting a limit block 31 on the right angle opposite side of the "L"-shaped block, the movable mold 2 is limited to deviate outward to form a right angle bend.

[0033] Furthermore, an inclined surface 32 is provided on the inner side of the limiting block 31 .

[0034] The inclined surface 32 is provided to form a slowly inward squeezing force during the pressing process. A preferably inclined surface 32 has a small vertical surface at its lower end; a waste groove 13 is also provided at the junction of the inclined surface 32 and the reset module 3 or at the junction of the vertical surface and the reset module 3, or an avoidance guide angle is provided at the right angle of the movable module 2 corresponding to the junction. The inclined surface 32 can be set to 70°-85°.

[0035] Furthermore, guide holes 14 are provided at intervals in the installation groove 11 , and guide rods 15 are provided in the reset module 3 corresponding to the guide holes 14 .

[0036] It plays a guiding role in the up and down movement of the reset module 3.

[0037] Furthermore, the return spring 12 is sleeved on the guide rod 15 .

[0038] The return spring 12 is sleeved on the guide rod 15, which can effectively avoid deformation of the spring.

[0039] Furthermore, both ends of the lower mold 1 are provided with adjustment mechanisms (not shown), and the adjustment mechanisms are arranged on the working table of the bending machine.

[0040] The adjusting mechanism is used to adjust the position of the lower mold 1, so as to set the distance between the lower mold 1 and the movable mold 2 according to the plate thickness.

[0041] Furthermore, the adjustment mechanism is provided with an adjustment plate and an adjustment screw, the adjustment plates are respectively fixed on the front and rear working tables at both ends of the lower mold 1, the adjustment screws are respectively threadedly connected with the adjustment plates, and the front ends of the adjustment screws are respectively in contact with the lower mold 1.

[0042] By rotating the adjusting screw, the front and rear position of the lower module 1 is adjusted and a positioning function is achieved.

[0043] When in use, the position of the lower mold 1 is adjusted through the adjustment mechanism according to the thickness of the plate to be bent, and then the forming plate 4 to be bent is placed on the lower mold 1 and the reset mold 3 between the limit blocks 31, the bending machine is started, and the movable mold 2 descends to achieve the right-angle bending of the forming plate 4. When bending the door leaf, the traditional method is to first fold the two sides of the forming plate 4 and then fold it up and down, and when folding it up and down, two people must push it up at the same time. If they do not push it up, the door panel will be deformed. The mold bending of the present application needs to fold the top and bottom of the forming plate 4 first and then fold the two sides. If the two sides are folded first, when folding up and down, the mold will get stuck in the door panels bent on both sides and cause deformation. The improved bending does not need to push the forming plate 4 up when folding up and down, and can also ensure that the plate is not deformed, which reduces the work intensity of the staff and improves the bending quality and yield rate of the door leaf.

[0044] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
