Abstract
Description
Technical Field
[0001] The utility model relates to a device for pressing a casing pit. Background Art
[0002] The tube bundle assembly structure has a gap between the middle sleeve and the inner tube. A recess in the middle sleeve prevents the two components from supporting each other properly. Conventional production methods use pliers to create bosses at three points around a circle, and the operator uses manual force to press the middle sleeve into the recess. This method doesn't guarantee sufficient force to create the recess. Utility Model Content
[0003] The purpose of the utility model is to solve the above-mentioned problems and provide a device for pressing casing pits.
[0004] The above purpose is achieved through the following technical solutions:
[0005] A device for pressing a casing pit comprises an upper pressing block and a lower pressing block, wherein the upper pressing block and the lower pressing block are connected by bolts, the upper pressing block is provided with a punch hole, a punch is placed in the punch hole, and the lower pressing block is provided with two top holes, each of which has a top placed in it, and a steel plate is welded to the top hole.
[0006] The device for pressing the casing pit has the top holes on both sides positioned at 120 degrees. Beneficial effects
[0007] 1. The utility model designs a punch and a top, and by striking the upper punch, pits are processed on both sides through the extrusion top, thereby realizing one-time forming of three pits on the circumference of the middle sleeve, ensuring the production cycle and ensuring a safe working environment.
[0008] 2. The utility model provides an upper pressing block and a lower pressing block structure, which are fixed by bolts, making it convenient to assemble and disassemble the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Attachment Figure 2 It is a side view of the utility model;
[0011] In the figure: 1. Punch; 2. Upper pressure block; 3. Punch hole; 4. Bolt; 5. Center hole; 6. Center; 7. Steel plate; 8. Lower pressure block; 9. Middle casing. DETAILED DESCRIPTION
[0012] Reference Figure 1-Figure 2A device for pressing a casing pit, which consists of an upper pressing block 2 and a lower pressing block 8. The upper pressing block and the lower pressing block are connected by a bolt 4. A punch hole 3 is provided on the upper pressing block, and a punch 1 is placed in the punch hole. Two top holes 5 are provided on the lower pressing block, and a top 6 is placed in each of the top holes. A steel plate 7 is welded to the top hole.
[0013] The device for pressing the casing pit has the top holes on both sides positioned at 120 degrees.
[0014] Since there are three pit structures on a circumference, and the middle sleeve is more than 8000mm long, there is one pit structure every 500mm, which means there are 16 such structures on a single pipe. In order to process three pits at a time, a punch and a tip are designed at the corresponding positions. By hitting the upper punch, the punch punches out the pits on the middle sleeve 9. During the impact, the tips are squeezed on both sides to process the pits. Since the positions of the tips on both sides are 120 degrees, in order to facilitate the processing and installation of the tips, a tip hole is designed and then a steel plate is welded to the end of the tip hole to block it. Due to the large number of pits, the device is designed with an upper and lower pressure block connected by bolts to facilitate assembly and disassembly. This utility model mainly realizes the one-time molding of the three pits on the circumference of the middle sleeve, ensures the production cycle, ensures a safe working environment, solves the problem of the pit structure on the middle sleeve being difficult to form, and ensures smooth production progress. Therefore, this device for pressing the pits in the middle sleeve will reduce labor costs.
