Description

Technical Field

[0001] This utility model belongs to the field of pipe bending processing mold technology, specifically a pipe bending processing mold that facilitates unloading. Background Technology

[0002] Pipe bending is a common metal forming process widely used in piping systems, automobile manufacturing, aerospace and other fields. It usually involves bending straight pipes into specific angles and curvatures using mechanical force or heat. Common methods include cold bending and hot bending, with the latter being suitable for thick-walled pipes or high-hardness materials. Dies are special tools used for bending and forming metal pipes to ensure that the pipes maintain shape accuracy and reduce deformation during processing.

[0003] After processing, traditional pipe bending molds often cause the pipe to adhere tightly to the mold due to strong mechanical force, making unloading difficult. In this case, manual pushing, knocking, or prying with auxiliary tools is required, which affects efficiency and can easily damage the surface of the pipe. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a pipe bending processing mold that facilitates unloading, which solves the problem that the pipe is often tightly attached to the mold due to strong mechanical force, which leads to difficulty in unloading, requiring manual pushing, knocking or prying with auxiliary tools, affecting efficiency and easily damaging the surface of the pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe bending processing mold for easy unloading, comprising an upper mold and a lower mold, a fixed plate connected to the lower mold, side plates connected to both sides of the lower mold, a sliding groove formed at the lower part of the lower mold, guide grooves formed on the side plates, guide posts connected to the upper part of the side plates, and a main wedge block slidably disposed between the two side plates, a guide wheel rotatably mounted on the main wedge block, and sliders connected to both sides of the main wedge block;

[0006] The slide groove has two movable plates that are slidably connected inside. One end of each movable plate is connected to a secondary wedge block, and the other side of each movable plate is designed with a U-shaped groove. An inclined groove is opened on the wall of the U-shaped groove on one side of the movable plate. A hydraulic push rod is fixedly installed on the fixed plate. The movable end of the hydraulic push rod passes through the lower mold and is connected to a connecting plate. Push blocks are connected to both sides of the connecting plate.

[0007] As a further embodiment of this utility model: the connecting plate is slidably disposed in the U-shaped groove of the two movable plates, and the inclined grooves on the two movable plates together form a V-shaped structure, and the push block slides in the inclined groove.

[0008] As a further embodiment of this utility model: the main wedge block and the secondary wedge block are both designed with inclined surfaces on opposite sides and fit together at the inclined surfaces. The secondary wedge block and the movable plate are both located between the two side plates, and the movable plate is in close contact with the groove wall.

[0009] As a further embodiment of this utility model: guide sleeves are connected to both sides of the upper mold, and the guide sleeves are slidably connected to the guide posts and the guide posts penetrate the guide sleeves.

[0010] As a further embodiment of this utility model: the slider is T-shaped and slides in the guide groove, and a spring is connected to the slider, with one end of the spring connected to the wall of the guide groove.

[0011] As a further embodiment of this utility model: four fixing strip holes are provided on the fixing plate in a rectangular array, and an annular groove is provided in the middle of the guide wheel.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This easy-to-unload pipe bending die is equipped with a hydraulic push rod, connecting plate, push block, inclined groove, movable plate, main wedge block and secondary wedge block. After the pipe is bent, the operator activates the hydraulic push rod, which pulls the connecting plate so that the push block can slide in the inclined groove. The inclined groove wall then pushes the movable plate to slide, causing the movable plate to push the secondary wedge block to move. The moving secondary wedge block can then push the main wedge block upward through the inclined surface, which in turn causes the guide wheel on the main wedge block to push the pipe away from the lower die. This makes it easy for the operator to unload the pipe without manual pushing, knocking or prying with auxiliary tools, thus avoiding damage to the pipe surface.

[0014] 2. This easy-to-unload pipe bending die, by setting guide grooves, sliders, springs and guide wheels, allows the slider to slide synchronously in the guide groove when the secondary wedge block pushes the main wedge block upward, thereby guiding the movement of the main wedge block through the guide groove and preventing skewing during movement. The moving slider will compress the spring, and the spring's rebound will assist the main wedge block in resetting, thus achieving continuous unloading. The guide wheel can limit the pipe material through the annular groove in the middle position. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a pipe bending processing mold that facilitates unloading, including an upper mold 1 and a lower mold 2. A fixing plate 3 is connected to the lower mold 2. The fixing plate 3 has four fixing slots 18 in a rectangular array. An annular groove is provided in the middle of the guide wheel 9. The guide wheel 9 rotating on the main wedge block 8 can assist the worker in pushing the pipe, so that the bending area of ​​the pipe can be moved to the lower mold 2. The annular groove on the guide wheel 9 can limit the pipe and prevent it from tilting when pushing.

[0022] The lower mold 2 is connected to side plates 4 on both sides. A sliding groove 5 is provided below the lower mold 2. A guide groove 6 is provided on the side plate 4. A guide post 7 is connected above the side plate 4. A main wedge block 8 is slidably arranged between the two side plates 4. The upper mold 1 is connected to guide sleeves 101 on both sides. The guide sleeves 101 are slidably connected to the guide posts 7 and the guide posts 7 pass through the guide sleeves 101. When the upper mold 1 moves down to perform the bending operation, the guide sleeves 101 will slide on the guide posts 7, thereby restricting the movement of the upper mold 1 and preventing deviation.

[0023] Both the main wedge block 8 and the secondary wedge block 12 have an inclined surface design on their opposite sides, and the inclined surfaces fit together. The secondary wedge block 12 and the movable plate 11 are located between the two side plates 4, and the movable plate 11 is in close contact with the groove wall of the slide 5. Through the contact between the movable plate 11 and the groove wall of the slide 5, the slide 5 can restrict the movable plate 11, so that the movable plate 11 can slide smoothly in the slide 5 and prevent the movable plate 11 from deviating when moving.

[0024] A guide wheel 9 is rotatably mounted on the main wedge block 8. Sliders 10 are connected to both sides of the main wedge block 8. The sliders 10 are T-shaped and slide within the guide groove 6. A spring 17 is connected to the sliders 10. One end of the spring 17 is connected to the wall of the guide groove 6. The sliding of the sliders 10 within the guide groove 6 guides the main wedge block 8, allowing it to move smoothly upwards and push out the pipe, thus facilitating unloading by the workers.

[0025] The chute 5 has two sliding plates 11 connected inside. One end of the sliding plate 11 is connected to a secondary wedge block 12, and the other side of the sliding plate 11 is designed with a U-shaped groove. An inclined groove 13 is opened on the wall of the U-shaped groove on one side of the sliding plate 11. A hydraulic push rod 14 is fixedly installed on the fixed plate 3. The movable end of the hydraulic push rod 14 passes through the lower mold 2 and is connected to a connecting plate 15. Push blocks 16 are connected to both sides of the connecting plate 15. The connecting plate 15 is slidably set in the U-shaped groove of the two sliding plates 11, and the inclined grooves 13 on the two sliding plates 11 together form a V-shaped structure. The push block 16 slides in the inclined groove 13. The hydraulic push rod 14 pulls the connecting plate 15, causing the push block 16 to move along the inclined groove 13 on the sliding plate 11, forcing the two sliding plates 11 to slide outward synchronously, driving the secondary wedge block 12 to move laterally. The secondary wedge block 12 cooperates with the inclined surface of the main wedge block 8 to convert the lateral movement into a vertical lifting force, thereby smoothly ejecting the bent pipe, realizing fast automatic unloading, and reducing manual intervention.

[0026] The working principle of this utility model is as follows:

[0027] After the pipe is bent, the hydraulic push rod 14 is activated, which pulls the connecting plate 15 to move, causing the push block 16 to slide in the inclined groove 13. The push block 16 then pushes the movable plate 11 to slide through the groove wall of the inclined groove 13, thereby causing the secondary wedge block 12 to move laterally. As the secondary wedge block 12 moves, it engages with the inclined surface of the main wedge block 8, allowing the secondary wedge block 12 to lift the main wedge block 8. This allows the guide wheel 9 on the main wedge block 8 to push the pipe away from the lower mold 2. When the main wedge block 8 moves upward, the slider 10 slides synchronously in the guide groove 6, guiding the movement of the main wedge block 8 and preventing it from tilting during movement. The spring 17 is compressed by the slider 10, so when the movable plate 11 and the secondary wedge block 12 move back, the spring 17 pushes the main wedge block 8 to reset, thus achieving continuous unloading.
