Detailed Embodiment

[0020] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following will further describe the present utility model in detail with reference to the drawings. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] The following will be combined with Figures 1 to 5A detailed description is given to a bending device for a water heater reinforcement plate according to an embodiment of the present utility model.

[0022] As Figures 1 - 5 shown, a bending device for a water heater reinforcement plate includes an upper loading plate 1, a bearing box 2, and an upper die head 4 fixed to the bottom of the upper loading plate 1. Specifically, two sliding grooves 22 are provided on both sides of the bearing box 2, and two groups of lower die components 5 are provided between the two sliding grooves 22.

[0023] As Figure 3 shown, the lower die component 5 includes a shaft member 51, a right-angle groove 53 is formed on the shaft member 51, limiting plates 52 are fixed on both sides of the shaft member 51, and the outer sides of the limiting plates 52 are rotatably mounted on inner plates 54. The inner plates 54 are respectively connected to outer plates 56 through sliders 55. Threaded holes are provided on the outer plates 56, and locking screws 57 are installed in the threaded holes. The two sliders 55 are respectively slidably arranged in the sliding grooves 22.

[0024] The working principle of the above mechanism is: before use, the upper loading plate 1 is fixed to the output shaft of the press. As Figure 4 shown, the reinforcement plate 6 to be bent is placed above the two shaft members 51. The press is started, and the upper loading plate 1 drives the upper die head 4 to press down on the reinforcement plate 6. Under the action of pressure, the two shaft members 51 rotate 90 degrees along the Figure 4 arrow direction in Figure 5 shown position, and the bending is completed. During the bending process, the rotation of the shaft member 51 can reduce its relative displacement with the reinforcement plate 6, that is, reduce the friction between the two, and play a protective role for the reinforcement plate 6. The limiting plates 52 are used for limiting the two sides of the reinforcement plate 6 to be bent, so that the reinforcement plate 6 to be bent is located directly above the shaft member 51.

[0025] Among them, since a right-angle groove 53 is formed on the shaft member 51, its center of gravity moves downward. After being bent, under the action of gravity, the right-angle groove 53 automatically faces upward, realizing the automatic demoulding of the reinforcement plate 6.

[0026] On the basis of the above structure, in order to prevent relative displacement between the upper loading plate 1 and the bearing box during the bending process, resulting in unqualified bending parts, the following structure is adopted. Specifically, a guiding component 3 is provided between the upper loading plate 1 and the bearing box 2. The guiding component 3 includes a sleeve fixedly connected to the bearing box 2 and a guiding shaft fixedly connected to the upper loading plate 1. More specifically, a spring is provided in the sleeve, and the bottom of the guiding shaft is fixedly connected to the spring (not shown in the figure).

[0027] Based on the above structure, in this embodiment, the upper die head 4 has a cube structure. Two groups of lower die assemblies 5 are symmetrically arranged on both sides of the upper die head 4, and the axial distance between the two shaft members 51 is greater than the side length of the upper die head 4, that is, the upper die head 4 is located between the axes of the two shaft members 51, which can prevent the shaft members 51 from not being able to rotate 90 degrees when pressed down, causing interference between the upper die head 4 and the shaft members 51 and resulting in damage.

[0028] More specifically, the bearing box 2 includes a box body 21. The sliding grooves 22 are symmetrically arranged on both sides of the box body, and a scale 23 is provided above the sliding grooves 22. The scale 23 is used to measure the distance between the two groups of lower die assemblies 5, facilitating the accurate positioning of the two groups of lower die assemblies 5.

[0029] The working principle of the bending device for the water heater reinforcing plate of the present utility model is as follows:

[0030] Before use, according to the side length of the upper die head 4 and referring to the scale 23, move the two groups of lower die assemblies 5 to the set positions, and then fix the two groups of lower die assemblies 5 to the bearing box 2 through the locking screws 57. Then, fix the upper loading plate 1 to the output shaft of the press.

[0031] As Figure 4 shown, place the reinforcing plate 6 to be bent above the two shaft members 51, start the press, the upper loading plate 1 drives the upper die head 4 to press down on the reinforcing plate 6. Under the action of pressure, the two shaft members 51 rotate 90 degrees along the Figure 4 arrow direction in Figure 5 shown position, and the bending is completed. During the bending process, the rotation of the shaft members 51 can reduce their relative displacement with the reinforcing plate 6, that is, reduce the friction between the two, playing a protective role for the reinforcing plate 6.

[0032] After the bending is completed, the shaft members 51 reset under the action of gravity, realizing the automatic demolding of the reinforcing plate 6.

[0033] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present utility model without departing from the spirit and scope of the embodiments of the present utility model. Thus, if these modifications and variations of the embodiments of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these changes and modifications.
