Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of machining tooling, and particularly relates to a bending tooling for a tray valve sheet. Background Art
[0002] The floating valve tray is the most commonly used tray. It has many square or circular holes on the tray, and each hole is equipped with a valve sheet. The gas pushes the valve sheet upward through the valve hole and shoots out horizontally. When passing through the liquid layer, the gas and liquid are in a foam state for heat transfer and mass transfer processes. Since the opening of the valve sheet can vary with the gas velocity, the valve sheet can automatically close under the action of gravity at low gas velocities, reducing leakage. Therefore, it has the advantages of high efficiency and large elasticity; moreover, it has a simple structure, low cost, and high processing capacity.
[0003] The tray valve sheet in the prior art is as Figure 1 shown. The tray valve sheet is provided with a bending portion, so that after the tray valve sheet is inserted into the hole position on the tray, the position of the tray valve sheet can be limited by bending the bending portion of the tray valve sheet. However, after the tray valve sheet is inserted into the tray, the bending portion of the tray valve sheet is interfered by the tray, making it difficult to perform the bending operation. At the same time, since the bending portion in the tray valve sheet is small, it is difficult for the staff to complete the bending operation. Summary of the Utility Model
[0004] In order to make up for the deficiencies of the prior art, the utility model provides a bending tooling for a tray valve sheet to solve the technical problem of difficult processing after the tray valve sheet is loaded.
[0005] To achieve the above object, the specific technical solution of the utility model is as follows:
[0006] A bending tooling for a tray valve sheet includes a tooling base, a slider, and a driving component. A limiting groove adapted to the shape of the tray valve sheet is formed on the top surface of the tooling base. A sliding groove communicating with the limiting groove is formed inside the tooling base. The slider is slidably connected in the sliding groove.
[0007] The slider is divided into a driving section and a bending section. A first inclined surface cooperating with the driving component is provided on the driving section of the slider, and it can move outward under the push of the driving component. An elastic member is provided outside the driving section of the slider for driving the slider to reset when the driving component releases the thrust.
[0008] Further, the driving component includes a pneumatic element and a push block. The push block is fixed on the telescopic shaft of the pneumatic element and can move along the vertical direction under the drive of the pneumatic element. A second inclined surface cooperating with the first inclined surface on the slider is provided at the end of the push block.
[0009] Further, the elastic member adopts a return spring.
[0010] Furthermore, a stopper is fixed in the slide groove of the tooling base. A mounting hole is provided at the center of the stopper. The reset spring is embedded in the mounting hole, and the outer end thereof abuts against the outer side surface of the driving section of the slider.
[0011] Furthermore, the limiting groove is divided into a limiting section and a release section. An arc chamfer is provided at the connection between the limiting section and the release section.
[0012] Furthermore, the cross section of the bending section of the slider is rectangular.
[0013] Compared with the prior art, the utility model has the following advantages:
[0014] 1. The utility model cooperates with the slider and the driving assembly so that the slider can be slidably connected and move in the slide groove, and the tower plate valve sheet is bent during the sliding process, which facilitates the workers' bending operation of the tower plate valve sheet and improves the processing efficiency.
[0015] 2. The utility model sets the pneumatic element vertically so that it can make way for the end of the tower plate valve sheet away from the end that needs to be bent, thereby avoiding interference between the pneumatic element and the tower plate valve sheet when the slider is pushed to slide.

[0022] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "central", "end part", "length", "outer end", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0023] The present utility model will be further described below with reference to the drawings.
[0024] As Figure 2 and 3 shown, a bending tooling for a tray valve plate 8 includes a tooling base 1, a slider 2 and a driving component. Among them, a limiting groove 4 adapted to the shape of the tray valve plate 8 is provided on the top surface of the tooling base 1. The bending part 8-1 of the tray valve plate 8 to be bent is inserted into the limiting groove 4, and the bending operation can be completed under the action of the slider 2. A chute communicating with the limiting groove 4 is provided inside the tooling base 1. The slider 2 is slidably connected in the chute and can move in the chute under the push of the driving component to complete the bending of the tray valve plate 8.
[0025] As Figure 4 and 5 shown, the slider 2 is divided into a driving section 2-1 and a bending section 2-2. Among them, the inner side of the driving section 2-1 is a first inclined surface adapted to the driving component. When the driving component pushes the slider 2 along the length direction perpendicular to the chute, the slider 2 can move along the length direction of the chute under the cooperation and limitation of the first inclined surface and the chute.
[0026] The cross section of the bending section 2-2 is rectangular. When the slider 2 moves along the length direction of the chute under the drive of the driving component, the bending section 2-2 in the slider 2 bends the bending part 8-1 of the tray valve plate 8 inserted in the limiting groove 4, so that the bent tray valve plate 8 can be limited on the tray.
[0027] Furthermore, a stop block 5 is fixed in the chute of the tooling base 1 to limit the extreme position of the outward movement of the slider 2. An installation hole is provided at the center of the stop block 5. A return spring 7 is embedded in the installation hole. The outer end of the return spring 7 abuts against the other side of the driving section 2-1 of the slider 2. When the driving component releases the thrust applied to the first inclined surface, the return spring 7 will push the slider 2 to reset, so that the bending section 2-2 in the slider 2 is away from the limiting groove 4, so that the tray valve plate 8 undergoing the bending process can smoothly disengage from the limiting groove 4, preparing for the subsequent processing of the tray valve plate 8.
[0028] In this embodiment, as Figure 2 shown, the limit groove 4 is divided into a limiting section 4-1 and a tripping section 4-2. Among them, the tripping section 4-2 is provided to cooperate with the tray valve sheet 8 bent by the slider 2 so that it can be smoothly disengaged. Further, an arc chamfer is provided at the connection between the limiting section 4-1 and the tripping section 4-2.
[0029] As Figure 4 shown, the driving assembly includes a pneumatic element 6 and a push block 3. Among them, the push block 3 is fixed on the telescopic shaft of the pneumatic element 6 and can move along the vertical direction under the drive of the pneumatic element 6. A second inclined surface matching the first inclined surface on the slider 2 is provided at the end of the push block 3. When the second inclined surface contacts the first inclined surface, the push block 3 continues to move under the push of the pneumatic element 6, and the slider 2 moves along the horizontal direction under the limitation of the chute, thereby completing the bending operation of the tray valve sheet 8.
[0030] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
