Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, and more specifically to a device for pressing right angles and curved surfaces of workpieces. Background Technology

[0002] Steel is widely used in many industries due to its high strength and numerous advantages. Among them, steel plates have many applications. In the process of using steel plates, they often need to be bent to form steel plates with a certain curvature, which requires the use of a bending machine.

[0003] Currently, when steel bending machines perform bending operations, the shape of the bending die plate is generally fixed, resulting in a fixed shape for the pressed steel plate. However, some products require pressing both right angles and curved surfaces onto the steel plate during processing. Therefore, it is necessary to change the bending machine or the bending die plate of the bending machine. Both of these operations are relatively complex and require multiple people to cooperate, resulting in discontinuous operation. This makes it difficult to achieve continuous pressing of right angles and curved surfaces, increasing labor costs, reducing pressing efficiency, and affecting the stability and accuracy of the pressing process. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems by providing a device for pressing right angles and curved surfaces of workpieces, which can achieve continuous pressing of straight edges and curved surfaces of the clamping plate by relying on a simple mechanism.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a device for pressing right angles and arc-shaped surfaces of workpieces, comprising an operating table panel, a groove on the right side of the upper surface of the operating table panel, a deep groove ball bearing fixedly installed on the inner wall of the groove, a short rotating shaft installed on the inner side of the deep groove ball bearing, a rotating bracket fixedly connected to the top of the short rotating shaft, a rotating joint installed on the outer side of the rotating bracket, a pressing rod installed at the other end of the rotating joint, and an arc-shaped pressing mold and a right angle pressing mold fixedly connected to the upper and lower sides of the outer wall of the pressing rod, respectively; a right angle pressing fixture and an arc-shaped pressing fixture are respectively provided on the left and right sides below the pressing rod, and the bottoms of the right angle pressing fixture and the arc-shaped pressing fixture are fixedly connected to the upper surface of the operating table panel; and multiple supports are fixedly installed on the lower surface of the operating table panel.

[0006] To enable the pressing rod to rotate freely and facilitate continuous pressing operations, as a preferred embodiment of this invention for pressing right-angled and arc-shaped surfaces of workpieces, a retaining shaft is installed through the middle of the upper side of the rotating bracket. A connecting shaft is rotatably fitted onto the outer side of the retaining shaft, and the connecting shaft and the retaining shaft are limited by two through-hole conical pins. A cross-shaped universal coupling is installed at the upper end of the connecting shaft, and the cross-shaped universal coupling and the connecting shaft are limited by one through-hole conical pin. The other end of the cross-shaped universal coupling is fixedly installed to the rod connector by an elastic cylindrical pin, and the rod connector is fixed to the end of the pressing rod near the rotating joint.

[0007] To facilitate stable support of the operating table panel, as a preferred embodiment of this utility model for pressing right angles and arc surfaces of workpieces, the support includes a round tube column fixedly connected to the lower end face of the operating table panel. The lower end of the round tube column is fixedly connected to a base plate. Multiple expansion bolts are connected through the base plate to the ground. Nuts for limiting the position of the base plate are threaded onto the outer side of each of the multiple expansion bolts.

[0008] To increase the connection strength between the round tube column and the operating table panel, as a preferred embodiment of this utility model for pressing right angles and arc surfaces of workpieces, a column tie plate is fixedly connected between the round tube column and the operating table panel.

[0009] In order to enable the mold and fixture to work together to quickly press right-angle shapes, as a preferred device for pressing right angles and arc surfaces of workpieces according to this utility model, the cross-section of the right-angle pressing fixture is "M" shaped and the cross-section of the right-angle pressing mold is conical.

[0010] In order to enable the mold and fixture to work together to quickly press arc shapes, as a preferred embodiment of this utility model for pressing right angles and arc surfaces of workpieces, the inner diameter of the arc pressing mold is larger than the outer diameter of the arc pressing fixture.

[0011] The beneficial effects of this utility model are as follows: By setting a rotating bracket on the operating panel, the rotating bracket can be rotated to any required angle, thereby allowing the pressing rod to rotate horizontally at will through the rotating bracket, so that the mold can quickly fit with the corresponding jig; by welding arc-shaped pressing molds and right-angle pressing molds at corresponding positions above and below the pressing rod, right-angle molds and arc molds are integrated into the same equipment, and a cross-shaft universal coupling is set in the rotating joint, which allows the pressing rod to rotate 360°, so that the operator can quickly flip the other side of the pressing rod after pressing the right angle of the steel to press the arc surface, thereby realizing continuous pressing of right angles and arcs, and improving the working efficiency of pressing the right angle and arc surface of the same steel at the same time.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Please see Figure 1-6This utility model provides the following technical solution: a device for pressing right angles and arc surfaces of workpieces, including an operating table panel 6. A groove is provided on the right side of the upper end face of the operating table panel 6. A deep groove ball bearing 21 is fixedly installed on the inner wall of the groove. A rotating short shaft 19 is installed on the inner side of the deep groove ball bearing 21. A rotating bracket 17 is fixedly connected to the top of the rotating short shaft 19. A rotating joint is installed on the outer side of the rotating bracket 17. A pressing rod 7 is installed at the other end of the rotating joint. An arc-shaped pressing mold 15 and a right angle pressing mold 16 are fixedly connected to the upper and lower sides of the outer wall of the pressing rod 7, respectively. A right angle pressing fixture 18 and an arc-shaped pressing fixture 20 are respectively provided on the left and right sides below the pressing rod 7. Multiple supports are fixedly installed on the lower end face of the operating table panel 6.

[0022] In this embodiment: multiple supports are used to stably support the operating table panel 6. The operating table panel 6 is used to install the pressing mechanism and place the profile to be pressed. The rotating bracket 17 enables the pressing rod 7 to rotate horizontally. The rotating joint between the rotating bracket 17 and the pressing rod 7 enables the pressing rod 7 to rotate freely 360°. The pressing rod 7 drives the mold to fit with the corresponding die up and down to complete one pressing operation. By rotating the pressing rod 7 horizontally to position it above another die, and then rotating the pressing rod 7 itself to make the corresponding mold rotate to the downward direction, a second pressing operation is completed, thereby achieving the effect of continuously pressing straight edges or arcs.

[0023] As a technical optimization of this utility model, a retaining shaft 14 is installed through the middle of the upper side of the rotating bracket 17, and a connecting shaft 12 is rotatably fitted on the outer side of the retaining shaft 14. The connecting shaft 12 and the retaining shaft 14 are limited by a tapered pin 13. A cross-shaped universal coupling 10 is installed at the upper end of the connecting shaft 12. The cross-shaped universal coupling 10 and the connecting shaft 12 are limited by a tapered pin 11. The other end of the cross-shaped universal coupling 10 is fixedly installed to the rod connector 8 by an elastic cylindrical pin 9. The rod connector 8 is fixed to the end of the pressing rod 7 near the rotating joint.

[0024] In this embodiment, the connection structure of the retaining shaft 14, the cross-shaped universal coupling 10, the connecting shaft 12, and the rod connector 8 allows the pressing rod 7 to rotate 360°. The tapered pin 11, tapered pin 2 13, and elastic cylindrical pin 9 are used to connect the above-mentioned connecting shafts or joints.

[0025] As a technical optimization of this utility model, the support includes a round tube column 4 fixedly connected to the lower end face of the operating panel 6. The lower end of the round tube column 4 is fixedly connected to a base plate 2. Multiple expansion bolts 1 are connected through the base plate 2 and the ground. Nuts 3 for limiting the base plate 2 are threaded to the outer side of the multiple expansion bolts 1. A column tie plate 5 is fixedly connected between the round tube column 4 and the operating panel 6.

[0026] In this embodiment: the bottom of the support is fixedly installed to the bottom surface of the operating area, and the upper end of the support is fixedly installed to the operating table panel 6, thereby stably fixing and supporting the overall pressing equipment.

[0027] As a technical optimization of this utility model, the cross-section of the right-angle pressing die 18 is "M" shaped, and the cross-section of the right-angle pressing mold 16 is conical; the inner diameter of the arc-shaped pressing mold 15 is larger than the outer diameter of the arc-shaped pressing die 20.

[0028] In this embodiment, the "V" shaped groove at the center of the "M"-shaped right-angle pressing jig 18 is adapted to the conical right-angle pressing mold 16, and the inclined plates on both sides of the "V" shaped groove can provide support to prevent the "V" shaped groove from deforming during the pressing process; the arc-shaped pressing mold 15 is adapted to the arc-shaped pressing jig 20, and the arc-shaped pressing mold 15 can completely cover the arc-shaped pressing jig 20, thereby achieving the effect of pressing arc-shaped profiles.

[0029] The working principle and usage process of this utility model are as follows: When pressing the profile, the steel profile is first placed on the right-angle pressing jig 18. The pressing rod 7 drives the right-angle pressing mold 16 to move down. The conical head of the mold cooperates with the "V" shaped groove of the jig, thereby pressing the profile into a right-angle shape. When it is necessary to press an arc shape, due to the setting of the rotating bracket 17, the end of the pressing rod 7 that fixes the mold can be rotated forward horizontally. When the end of the pressing rod 7 rotates to the arc pressing jig 20 and stops moving, the pressing rod 7 itself rotates, thereby making the arc pressing mold 15 face downward. The pressing rod 7 drives the arc pressing mold 15 to cooperate with the arc pressing jig 20, thereby pressing the profile into an arc shape, thus achieving rapid and continuous pressing of right-angle and arc structures on the same profile.

[0030] The manufacturing process of this utility model is as follows:

[0031] 1) First, determine the location of the pressing site. Select two round pipes as round pipe columns. Weld one end of the column to two 140mm x 140mm, 10mm thick anchor steel plates. Fix them to the selected operating site with 8 M12mm expansion bolts, nuts and spring washers. Weld the other end of the column to a 650mm x 400mm, 30mm thick steel plate as the operating table panel. Weld the table panel to the columns on both sides of the two columns with 10mm thick column tie plates to make the table panel fixed and stable, and the height of the table panel is suitable for the operator's pressing operation.

[0032] 2) Select two equilateral triangles (∠40x40x3mm, 100mm in length) and semicircular tubes (φ100x6mm, 120mm in length). Weld them to appropriate positions on one end of the operating table panel according to the requirements of the top and left views of the pressing device, ensuring the accuracy of the right-angled sides and the arc surface of the pressed U-shaped plate. Machin a hole of a certain depth at an appropriate position on the other end of the operating table panel. Install a 6206-2Z deep groove ball bearing with dust covers on both sides inside the hole. Install a 30mm long rotating short shaft inside the bearing, allowing the short shaft to rotate within the bearing.

[0033] 3) Use a steel plate with dimensions of 100x300mm and a thickness of 10mm as the base plate of the rotating bracket. Make a hole in the center of the base plate and insert the other end of the rotating short shaft. Weld two 60x80x10mm vertical plates at both ends of the upper surface of the base plate. Insert a long shaft with a diameter of φ30mm and a length of 300mm into the center hole of the two vertical plates. Weld the long shaft between the two vertical plates. In this way, the bracket can be connected to the bearing by rotating the short shaft, so that the bracket can be rotated arbitrarily through the bearing.

[0034] 4) Drill a hole 8mm deep at the center of the long shaft of the rotating bracket, insert a φ20mm round steel bar with a length of 30mm as a retaining shaft, and connect it to the connecting shaft with a φ6 tapered pin. The connecting shaft is then connected to the WS4 universal joint with a tapered pin.

[0035] 5) Use a φ38x3mm round tube with a length of 850mm as a pressing rod. One end of the pressing rod is connected to the cross-shaft universal coupling WS4 with a connecting rod joint. The other end of the pressing rod is welded with the right-angle pressing die and the arc pressing die at the positions corresponding to the right-angle pressing die and the arc pressing die. In this way, the pressing rod can rotate left and right as well as rotate in a circle, so that the pressing work can be carried out continuously and the pressing time of the operator is greatly reduced.

[0036] In summary, traditional pressing plates, due to the pressing fixtures being operated in different locations, require operators to press right angles before moving on to the pressing areas for curved surfaces, wasting pressing time, increasing operator workload, and resulting in inconsistent finished product dimensions and a lower pass rate. Furthermore, pressing in different locations also reduces work efficiency. However, the pressing device of this invention allows operators to press both right angles and curved surfaces on the same worktable. Through a rotating bracket and a cross-shaft universal coupling WS4, the pressing rod can move horizontally and rotate freely, enabling continuous pressing of right angles and curved surfaces. This streamlined process significantly reduces worker workload, greatly improves work efficiency, and increases the pass rate.

[0037] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
