Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to a steel pipe flaring stamping die. Background Technology

[0002] A flaring tool is used to expand the open end of a hollow or tubular component outwards. Currently, most steel pipe flaring is done on a lathe, but the flaring quality is poor, and breakage is common, leading to higher production costs and affecting the efficiency of steel pipe flaring. Utility Model Content

[0003] The purpose of this invention is to address the problem that most steel pipe flaring is done on a lathe, resulting in poor flaring quality, easy breakage, and high production costs, thus affecting the efficiency of steel pipe flaring. Therefore, this invention proposes a steel pipe flaring stamping die.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A steel pipe flaring stamping die includes an upper die base, a lower die base, and a steel pipe body. An upper pad is fixedly connected to the bottom of the upper die base, and an upper clamping plate is fixedly connected to the bottom of the upper pad. Two insert cutters are fixedly inserted into the bottom of the upper clamping plate, and a punch is fixedly connected to the bottom of the upper clamping plate. A lower pad is fixedly connected to the top of the lower die base, and a lower clamping plate is fixedly connected to the top of the lower clamping plate. The lower clamping plate is located below the upper clamping plate. A stop is fixedly connected to the top of the lower die base, and two die sliders are slidably connected to the top of the lower die base. The insert cutters contact the die sliders, and the steel pipe body is clamped between the two die sliders.

[0006] Furthermore, two guide shafts are fixedly connected to the top of the lower mold base.

[0007] Furthermore, the bottom of the upper mold base is fixedly connected to two outer guide sleeves, and the top end of the guide shaft is slidably inserted into the outer guide sleeves.

[0008] Furthermore, both ends of the lower clamping plate are fixedly connected to a protective sleeve, and a connecting shaft is slidably connected inside the protective sleeve. One end of the connecting shaft passes through the lower clamping plate and the stop block and is fixedly inserted into the die slider.

[0009] Furthermore, a spring is sleeved on the outer wall of the connecting shaft, with one end of the spring fixedly connected to the inner wall of the sleeve and the other end of the spring fixedly connected to the lower clamping plate.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. The punch moves downward, causing the punch to move downward, which in turn inserts the punch into the steel pipe body. The punch and the die slide cooperate to press out the product shape, improving the quality of the flaring.

[0012] 2. Driven by the punch press, the upper die holder, upper backing plate, and upper clamping plate move downward, thereby driving the cutting tool to move downward and press the die slider inward, which in turn causes the two die sliders to converge in the middle, thus clamping the steel pipe body for subsequent flaring operation.

[0013] 3. By moving the connecting shaft outward under the action of the spring, the die slider moves outward, thereby releasing the clamping of the steel pipe body so that the steel pipe body can be removed. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3A steel pipe flaring and stamping die includes an upper die base 1, a lower die base 7, and a steel pipe body 10. An upper pad 2 is bolted to the bottom of the upper die base 1, and an upper clamping plate 3 is bolted to the bottom of the upper pad 2. Two insert cutters 13 are fixedly inserted into the bottom of the upper clamping plate 3, and a punch 14 is bolted to the bottom of the upper clamping plate 3. A lower pad 6 is bolted to the top of the lower die base 7, and a lower clamping plate 5 is bolted to the top of the lower pad 6. A lower template 4 is bolted to the top of the lower clamping plate 5, and the lower template 4 is located below the upper clamping plate 3. Two guide shafts 11 are welded to the top of the lower die base 7, and two outer guide sleeves 12 are welded to the bottom of the upper die base 1. The top ends of the guide shafts 11 and the outer guide sleeves 12... The sliding connection guides the movement of the steel pipe flaring stamping die. The top of the lower die base 7 is fixed with a stop block 8 by bolts. The top of the lower die base 7 is slidably connected to two die sliders 9. Driven by the punch, the upper die base 1, upper pad 2 and upper clamping plate 3 move downward, thereby driving the cutter 13 to move downward and squeeze the die sliders 9 inward, so that the two die sliders 9 converge in the middle, thus clamping the steel pipe body 10. The cutter 13 contacts the die sliders 9, and the steel pipe body 10 is clamped between the two die sliders 9. The punch moves downward, driving the punch 14 to move downward, so that the punch 14 inserts into the steel pipe body 10. Thus, the product shape is pressed out by the cooperation of the punch 14 and the die sliders 9.

[0020] Both ends of the lower clamping plate 5 are welded with sheaths 15. A connecting shaft 16 is slidably connected inside the sheaths 15. One end of the connecting shaft 16 passes through the lower clamping plate 5 and the stop block 8 and is fixedly inserted into the die slider 9. A spring 17 is sleeved on the outer wall of the connecting shaft 16. One end of the spring 17 is fixedly connected to the inner wall of the sheath 15, and the other end of the spring 17 is fixedly connected to the lower clamping plate 5. Under the action of the spring 17, the connecting shaft 16 moves outward, thereby driving the die slider 9 to move outward, and thus releasing the clamping of the steel pipe body 10.

[0021] The working principle of this embodiment is as follows: In use, firstly, the steel pipe body 10 is placed vertically on the top of the lower die base 7. Then, the punch provides downward movement power. Driven by the punch, the upper die base 1, the upper pad 2 and the upper clamping plate 3 move downward, thereby driving the insert 13 to move downward and press the die slider 9 inward. This causes the two die sliders 9 to converge in the middle, thus clamping the steel pipe body 10. Then, the punch continues to move downward, thereby driving the punch 14 to move downward, thus causing the punch 14 to insert into the steel pipe body 10. Thus, the product shape is pressed out by the cooperation of the punch 14 and the die slider 9.

[0022] Then, the punch press drives the upper die holder 1, the upper pad 2 and the upper clamping plate 3 to move upward, thereby driving the cutter 13 to move upward and separate from the die slider 9. Then, under the action of the spring 17, the connecting shaft 16 moves outward, thereby driving the die slider 9 to move outward, thus releasing the clamping of the steel pipe body 10. The punch press continues to move upward, moving the punch 14 upward and separating it from the steel pipe body 10. Then the steel pipe body 10 can be taken out.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
