Description

Technical Field

[0001] This utility model relates to the field of shaping mold technology, and more specifically to a three-way pipe shaping mold. Background Technology

[0002] A tee is a pipe fitting with three openings: one inlet and two outlets, or two inlets and one outlet. It is used where three identical or different pipes converge and is a type of pipe fitting. Its main function is to change the direction of fluid flow, achieving fluid splitting or merging, and it can also balance pressure in multi-pipe systems, ensuring stable pressure in each section of the pipe.

[0003] For example, a tee shaping device with prior art disclosure number CN207076806U utilizes the powerful and stable pressure of a driving device, namely a hydraulic cylinder, to apply pressure to the tee fitting as a whole through upper and lower molds with pipe grooves, so as to make it plastically deformed to achieve the requirement of correcting the slope of the tee branch pipe.

[0004] However, the existing technology described above still has the following problems in use: after welding, the pipe ends of the upper and lower tee pipes are prone to welding deformation and are not round enough to fit with the exhaust pipe, resulting in air leakage during later use and an increase in defective products. Based on this, this utility model provides a tee pipe shaping mold with high shaping efficiency. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a three-way pipe shaping mold. By adding side-forming wedges to the upper and lower molds, the three ends of the three-way pipe are shaped. The shaped ends can fit evenly with the exhaust pipe, improving the yield rate. Furthermore, by using an electric push rod to drive multiple feeding rods upward, the three-way pipe is automatically separated from the placement groove, thereby increasing the feeding speed and thus improving the shaping efficiency of the three-way pipe, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a three-way pipe shaping mold, including an upper mold and a lower mold, wherein a placement mold base is fixedly provided at the bottom of the upper mold and the top of the lower mold, and a placement groove adapted to the three-way pipe is opened on the side of the two placement mold bases that are close to each other. Side straightening wedges are provided on the rear side and both sides of the placement mold base located at the top of the lower mold, and each side straightening wedge includes a lower wedge block and an upper wedge block. The bottom of the lower wedge block is fixed to the top of the lower mold, and the top of the upper wedge block is fixed to the bottom of the upper mold. A shaping block is slidably provided on the lower wedge block, and multiple return springs are fixedly provided on the side of the shaping block near the placement mold base.

[0007] In a preferred embodiment, the bottom of the placement mold base located at the top of the lower mold is machined with a plurality of circular holes communicating with the placement groove. Each circular hole is provided with a feeding rod, and the top of the feeding rod is flush with the bottom wall of the placement groove. The bottom of the plurality of feeding rods is connected to a drive mechanism.

[0008] In a preferred embodiment, the driving mechanism includes a lifting plate, a receiving groove is provided on the top of the lower mold, the lifting plate is disposed in the receiving groove, and an electric push rod for driving the lifting plate to rise and fall is passed through the bottom of the lower mold. The electric push rod drives the lifting plate and the unloading rod to rise and fall automatically, thereby improving the unloading speed of the T-shaped pipe.

[0009] In a preferred embodiment, a fixing plate is fixedly sleeved on the outer wall of the electric push rod. The fixing plate is detachably fixed to the lower mold by two fastening bolts. The fixing plate improves the stability of the electric push rod, thereby improving the stability of the material feeding rod lifting.

[0010] In a preferred embodiment, guide pillars are fixedly provided at the four corners of the top of the lower mold, and positioning components corresponding to the guide pillars are fixedly provided at the bottom of the upper mold. Each positioning component has a positioning hole at its bottom that matches the guide pillar. The top of the guide pillar is located in the positioning hole. By using the guide pillar and the positioning hole to cooperate, the upper mold can be limited, thereby keeping the upper mold stable in lifting and lowering and avoiding the upper mold from shifting and affecting the shaping accuracy.

[0011] In a preferred embodiment, the top of the upper mold has multiple evenly distributed fixing holes, which facilitates the subsequent connection of the upper mold to the driving device. The driving device enables the upper mold to open and close automatically, thereby further improving the shaping efficiency of the T-shaped pipe.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This invention shapes the three ends of a tee pipe by adding side-aligning wedges to the upper and lower molds. The shaped ends can fit evenly with the exhaust pipe, improving the yield rate. Furthermore, by using an electric push rod to move multiple feeding rods upward, the feeding rods separate the tee pipe from the placement groove, thereby increasing the feeding speed and thus improving the shaping efficiency of the tee pipe.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0023] Refer to the instruction manual appendix Figures 1-5 This utility model provides a three-way pipe shaping mold. The bottom of the upper mold 1 and the top of the lower mold 2 are both fixedly provided with a placement mold base 3. The two placement mold bases 3 are provided with a placement groove 4 adapted to the three-way pipe on the side close to each other. The placement mold base 3 at the top of the lower mold 2 is provided with a side straightening wedge 5 on the rear side and both sides. Each side straightening wedge 5 includes a lower wedge block 51 and an upper wedge block 52. The bottom of the lower wedge block 51 is fixed to the top of the lower mold 2, and the top of the upper wedge block 52 is fixed to the bottom of the upper mold 1. A shaping block 53 is slidably provided on the lower wedge block 51. Multiple return springs 54 are fixedly provided on the side of the shaping block 53 near the placement mold base 3.

[0024] To improve the positioning accuracy of the upper mold 1, guide pillars 9 are fixedly provided at the four corners of the top of the lower mold 2. Positioning components 10 corresponding to the guide pillars 9 are fixedly provided at the bottom of the upper mold 1. Each positioning component 10 has a positioning hole 11 adapted to the guide pillar 9 at its bottom. The top of the guide pillar 9 is located in the positioning hole 11. By using the cooperation between the guide pillar 9 and the positioning hole 11, the upper mold 1 can be limited, thereby keeping the upper mold 1 stable in lifting and lowering and avoiding the upper mold 1 from shifting and affecting the shaping accuracy.

[0025] The upper mold 1 has multiple evenly distributed fixing holes 12 on its top. The design of multiple fixing holes 12 facilitates the subsequent connection of the upper mold 1 to a driving device such as a hydraulic cylinder. With the help of the driving device, the upper mold 1 can be automatically opened and closed, thereby further improving the shaping efficiency of the T-shaped pipe.

[0026] In actual use, first open the upper mold 1, then place the welded tee pipe into the placement groove 4 at the top of the placement mold base 3 on the lower mold 2, then move the upper mold 1 down and move the multiple upper inclined wedges 52 at its bottom down together. The downward movement of the upper inclined wedges 52 pushes the shaping blocks 53 on the lower inclined wedges 51 to move towards the placement mold base 3. The placement groove 4 on the placement mold base 3 at the bottom of the upper mold 1 contacts the top of the tee pipe, and the multiple shaping blocks 53 are gradually inserted into the three pipe openings of the tee pipe for shaping. At this time, the multiple return springs 54 on the shaping blocks 53 are squeezed and contracted. Afterwards, when the upper mold 1 moves up and opens again, the shaping blocks 53 automatically return to their original position under the elastic force of the return springs 54. Then, use the unloading assembly to push the tee pipe out of the placement groove 4, which facilitates quick unloading and greatly improves the shaping efficiency of the tee pipe.

[0027] Refer to the instruction manual appendix Figures 1-5 The bottom of the placement mold base 3 located at the top of the lower mold 2 is machined with multiple round holes 6 that communicate with the placement groove 4. Each round hole 6 is provided with a feeding rod 7, and the top of the feeding rod 7 is flush with the bottom wall of the placement groove 4. The bottom of the multiple feeding rods 7 is connected to a drive mechanism 8. Specifically, the drive mechanism 8 includes a lifting plate 81. The top of the lower mold 2 is provided with a storage groove 82, and the lifting plate 81 is located in the storage groove 82. An electric push rod 83 for driving the lifting plate 81 to rise and fall is passed through the bottom of the lower mold 2.

[0028] When the T-tube is shaped and needs to be unloaded, the electric push rod 83 extends to drive the lifting plate 81 to move upward in the storage slot 82, and at the same time, it drives multiple unloading rods 7 to move upward together. The multiple unloading rods 7 extend from multiple round holes 6 to separate the T-tube from the placement slot 4, avoiding damage or injury caused by manually pulling the T-tube. This can improve the unloading speed and thus improve the shaping efficiency of the T-tube.

[0029] Furthermore, a fixing plate 84 is fixedly sleeved on the outer wall of the electric push rod 83. The fixing plate 84 is detachably fixed to the lower mold 2 by two fastening bolts 85. The fixing plate 84 improves the stability of the electric push rod 83, thereby improving the stability of the lifting of the unloading rod 7.

[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
