Description

Technical Field

[0001] This utility model relates to the field of end cap processing technology, specifically to an end cap segmentation forming device. Background Technology

[0002] End caps are end caps on pressure vessels, serving a sealing function. There are two main processing methods for end caps: integral forming and segmented forming. Integral forming refers to obtaining the finished end cap in one step according to predetermined technical requirements, suitable for small to medium diameter end caps; integral forming can be further subdivided into stamping, spinning, explosive forming, and gas / hydraulic expansion forming, etc. Segmented forming refers to pressing parts of the end cap into segments, then welding these parts together to form the final product, suitable for large diameter end caps that cannot be or are difficult to form integrally.

[0003] Currently, the weld width between the segments of the end cap is determined by the relative position between the two segments. If the position of the segments deviates, it may lead to a decrease in the weld strength and problems such as welding cracks and brittle fracture. Therefore, the butt joint position between the segments is very important. Hence, an end cap segment forming device is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a head segmentation forming device in response to the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a head segmentation forming device, including a processing table, a fixing mechanism is provided on the processing table, and a melon segment head is placed on the processing table;

[0006] The fixing mechanism includes a first limiting seat and a motor. A bidirectional screw is fixedly connected to the output end of the motor. A first connecting plate is fixedly connected to the bottom of the first limiting seat. The first connecting plate is threaded onto the bidirectional screw. A second connecting plate is threaded onto the bidirectional screw. A second limiting seat is fixedly connected to the second connecting plate. A fixing frame is fixedly connected to the first limiting seat. A cylinder is fixedly connected to the fixing frame. An adjusting plate is fixedly connected to the telescopic end of the cylinder. A pressure plate is provided below the adjusting plate.

[0007] Preferably, the motor is fixedly connected to the processing table, and a guide rod is fixedly connected to the adjustment plate. The guide rod is slidably connected to the fixed frame. The guide rod can limit the position of the adjustment plate, thereby making the adjustment plate more stable.

[0008] Preferably, the processing table has a guide opening, and a limit slider is slidably connected inside the guide opening. The limit slider is fixedly connected to the bottom of the first limit seat. The limit slider and the guide opening can play a limiting and guiding role for the first limit seat.

[0009] Preferably, a protective mechanism is provided between the adjusting plate and the pressure plate. The protective mechanism includes a guide post, which is fixedly connected to the pressure plate. The protective mechanism can protect the melon petal end cap.

[0010] Preferably, the adjusting plate has a guide hole, the guide post passes through the interior of the guide hole, and the upper end of the guide post is fixedly connected to a limit block. The limit block can prevent the guide post from detaching from the adjusting plate.

[0011] Preferably, a spring is fitted on the guide post, with the upper end of the spring abutting against the bottom of the adjusting plate and the lower end of the spring abutting against the pressure plate. The spring can prevent the pressure plate from being too strong.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This end cap segmentation forming equipment places two segmented end caps together on a processing table. Then, the motor is started to drive the bidirectional screw to rotate, causing the first and second limiting seats to approach each other and abut against the two segmented end caps respectively. This ensures that the welding edges of the two segmented end caps are tightly abutted together, preventing large gaps between the two segmented end caps from affecting the welding quality. Then, the cylinder is activated to lower the pressure plate, which presses down on the segmented end caps in conjunction with the limiting seats, thus limiting and fixing the position of the segmented end caps and preventing positional deviation. This further improves the welding strength during end cap welding and avoids welding cracks and brittle fracture.

[0014] 2. This end cap segmenting forming equipment, by setting guide columns and springs, can prevent the pressure plate from applying too much pressure to the segmented end cap, which would cause the segmented end cap to be deformed due to pressure. This plays a protective role for the segmented end cap and further improves the practicality of the forming equipment. Attached Figure Description

[0026] The fixing mechanism 2 includes a first limiting seat 201 and a motor 211. A bidirectional screw 209 is fixedly connected to the output end of the motor 211. A first connecting plate 202 is fixedly connected to the bottom of the first limiting seat 201. The first connecting plate 202 is threadedly connected to the bidirectional screw 209. A second connecting plate 210 is threadedly connected to the bidirectional screw 209. A second limiting seat 212 is fixedly connected to the second connecting plate 210. A fixing frame 203 is fixedly connected to the first limiting seat 201. A cylinder 204 is fixedly connected to the fixing frame 203. An adjusting plate 206 is fixedly connected to the telescopic end of the cylinder 204. A pressure plate 207 is provided below the adjusting plate 206. By adjusting the two... The two melon-shaped end caps 4 are placed together on the processing table 1. Then, the motor 211 is started to drive the bidirectional screw 209 to rotate, so that the first limiting seat 201 and the second limiting seat 212 move closer to each other and abut against the two melon-shaped end caps 4 respectively. This ensures that the welding edges of the two melon-shaped end caps 4 are tightly abutted together, avoiding large gaps between the two melon-shaped end caps 4 that would affect the welding quality. Then, the cylinder 204 is started to lower the pressure plate 207, which presses down on the melon-shaped end caps 4 and works with the limiting seats to limit and fix the position of the melon-shaped end caps 4, avoiding positional deviation. This further improves the welding strength during end cap welding and avoids welding cracks and brittle fracture.

[0027] The motor 211 is fixedly connected to the processing table 1. A guide rod 205 is fixedly connected to the adjusting plate 206. The guide rod 205 is slidably connected to the fixed frame 203. The guide rod 205 can limit the adjustment plate 206, thereby making the adjustment plate 206 more stable.

[0028] The processing table 1 has a guide opening 213. A limit slider 208 is slidably connected inside the guide opening 213. The limit slider 208 is fixedly connected to the bottom of the first limit seat 201. The limit slider 208 and the guide opening 213 can play a limiting and guiding role for the first limit seat 201.

[0029] Working principle: Two melon-shaped end caps 4 are placed together on the processing table 1. Then, the motor 211 is started to drive the bidirectional screw 209 to rotate, so that the first limiting seat 201 and the second limiting seat 212 approach each other and abut against the two melon-shaped end caps 4 respectively. This ensures that the welding edges of the two melon-shaped end caps 4 are tightly abutted together, avoiding large gaps between the two melon-shaped end caps 4 that would affect the welding quality. Then, the cylinder 204 is started to lower the pressure plate 207, which presses down on the melon-shaped end caps 4 and works with the limiting seats to limit and fix the position of the melon-shaped end caps 4, avoiding positional deviation. This further improves the welding strength during end cap welding and avoids welding cracks and brittle fracture.

[0030] Please see Figure 1-5 Based on the above embodiments, in another embodiment of the present invention, a protective mechanism 3 is provided between the adjusting plate 206 and the pressure plate 207. The protective mechanism 3 includes a guide post 301, which is fixedly connected to the pressure plate 207. The protective mechanism 3 can protect the melon petal end cap 4.

[0031] The adjusting plate 206 has a guide hole 303, and the guide post 301 passes through the interior of the guide hole 303. The upper end of the guide post 301 is fixedly connected to a limit block 304. The limit block 304 can prevent the guide post 301 from detaching from the adjusting plate 206.

[0032] A spring 302 is fitted on the guide post 301. The upper end of the spring 302 abuts against the bottom of the adjusting plate 206, and the lower end of the spring 302 abuts against the pressure plate 207. The spring 302 can prevent the pressure plate 207 from being too strong.

[0033] Working principle: By setting guide post 301 and spring 302, the buffering effect of spring 302 can avoid excessive pressure of pressure plate 207 on melon-shaped end cap 4, which would cause melon-shaped end cap 4 to be deformed due to pressure. This plays a protective role for melon-shaped end cap 4 and further improves the practicality of the molding equipment.

[0034] This utility model provides a head segmentation forming device. There are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
