Description

Technical Field

[0001] This utility model relates to the field of perforated guide plate technology, and in particular to a spliced ​​composite perforated guide plate that is easy to disassemble. Background Technology

[0002] High-temperature alloy hot piercing requires the use of piercing guide plates. Traditional piercing guide plates are made of high carbon and high chromium materials, and they are a prominent wear part in piercing machines.

[0003] For example, Chinese patent document CN222643038U discloses a guide plate cooling structure, which relates to the field of perforated guide plate technology. It describes that "it includes a perforated guide plate, and the perforated guide plate is provided with a contact wall that contacts and guides the high-temperature tube blank. The contact wall is an arc-shaped curved wall, and a cooling channel that penetrates the perforated guide plate is opened along the direction of the high-temperature tube blank's advance."

[0004] However, the following defects or problems still exist when combining existing technologies: traditional perforated guide plates are made of a single piece of wear-resistant material, and after wear, the whole plate needs to be replaced, which is very costly. Therefore, we designed a spliced ​​composite perforated guide plate that is easy to disassemble. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a conveniently disassembled, spliced ​​composite perforated guide plate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A modular composite perforated guide plate that is easy to disassemble includes a base, wherein a mounting groove is provided in the middle of the base, and a wear-resistant block is sleeved on the base at the mounting groove.

[0008] A limiting protrusion is fixedly connected to one side of the base, the limiting protrusion is located in the mounting groove, and a lower groove is opened on the outer side of the other side of the base, and a threaded hole is opened at the lower groove of the base;

[0009] The wear-resistant block has a second limiting groove on one side, which matches the limiting protrusion. The wear-resistant block has an upper groove on the outer wall of the other side, which corresponds to the lower groove.

[0010] The base is fitted with a fixing plate in the lower groove. The outer wall of the fixing plate is fitted with a screw. One end of the screw is threaded to the base through a threaded hole. The upper surface of the fixing plate extends into the upper groove of the wear-resistant block.

[0011] Preferably, the upper surface of the base is provided with a first working surface, which is an arc-shaped curved wall, and the upper surface of the wear-resistant block is provided with a second working surface, which is also an arc-shaped curved wall, and the horizontal height of the second working surface is higher than that of the first working surface.

[0012] Preferably, the base has first limiting slots on both sides of the mounting groove, and limiting protrusions are fixedly connected to both outer walls of the wear-resistant block. The limiting protrusions match the first limiting slots, and the limiting protrusions are engaged into the base through the first limiting slots.

[0013] Preferably, the limiting protrusion is integrally formed with the base, and the limiting protrusion is integrally formed with the wear-resistant block.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, a splicing method is used on the basis of traditional perforated guide plates to reduce the wear-resistant material at both ends. A wear-resistant block that can be easily disassembled and replaced is used in the middle to maintain the wear resistance of the middle. The wear-resistant block in the middle can be disassembled and replaced after it is worn, while the base can be used for a long time without frequent replacement. This perforated guide plate greatly reduces the cost compared to traditional perforated guide plates. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] As attached Figure 1 To be continued Figure 4 As shown:

[0023] A modular composite perforated guide plate that is easy to disassemble includes a base 1, a mounting groove 101 is provided in the middle of the base 1, and a wear-resistant block 2 is sleeved on the base 1 at the mounting groove 101.

[0024] A limiting protrusion 102 is fixedly connected to one side of the base 1. The limiting protrusion 102 is located at the mounting groove 101. A lower groove 104 is opened on the outside of the other side of the base 1. A threaded hole 105 is opened at the lower groove 104 of the base 1.

[0025] A second limiting groove 201 is provided on one side of the wear-resistant block 2, which matches the limiting protrusion 102. An upper groove 203 is provided on the outer wall of the other side of the wear-resistant block 2, which corresponds to the lower groove 104.

[0026] A fixing plate 3 is fitted onto the base 1 at the lower groove 104. A screw 4 is fitted onto the outer wall of the fixing plate 3. One end of the screw 4 is threaded to the base 1 through the threaded hole 105. The upper surface of the fixing plate 3 extends into the upper groove 203 at the wear-resistant block 2.

[0027] In the above technical solution, when the second working surface 204 on the wear-resistant block 2 is worn to a certain extent, we can replace the wear-resistant block 2 by loosening the screw 4, removing the fixing plate 3 at the lower groove 104, and then sliding the old wear-resistant block 2 outward through the side close to the lower groove 104.

[0028] Then, the new wear-resistant block 2 can be inserted into the mounting groove 101 through the side near the lower groove 104. The limiting protrusion 102 and the second limiting groove 201 can restrict one side of the wear-resistant block 2. Then, the fixing plate 3 is placed in the upper groove 203 and the lower groove 104. The screw 4 passes through the fixing plate 3 and is screwed into the threaded hole 105. Tighten the screw 4 to fix the fixing plate 3. The fixing plate 3 can restrict the other side of the wear-resistant block 2.

[0029] As attached Figure 1 To be continued Figure 3 As shown, the upper surface of the base 1 has a first working surface 106, which is an arc-shaped curved wall. The upper surface of the wear-resistant block 2 has a second working surface 204, which is also an arc-shaped curved wall. The horizontal height of the second working surface 204 is higher than that of the first working surface 106.

[0030] In the above technical solution, since the horizontal height of the second working surface 204 is higher than that of the first working surface 106, the second working surface 204 is the main contact surface of the pipe. When the second working surface 204 is worn, and the pipe and the first working surface 106 become the main contact surface, the wear-resistant block 2 needs to be replaced.

[0031] As attached Figure 1 To be continued Figure 3 As shown, the base 1 has a first limiting slot 103 on both sides of the mounting groove 101. The outer walls of both sides of the wear-resistant block 2 are fixedly connected to limiting protrusions 202. The limiting protrusions 202 match the first limiting slots 103 and are inserted into the base 1 through the first limiting slots 103.

[0032] In the above technical solution, the vertical direction of the wear-resistant block 2 can be limited by the cooperation between the limiting protrusion 202 and the first limiting slot 103, which can effectively prevent the wear-resistant block 2 from falling off.

[0033] As attached Figure 2 To be continued Figure 3 As shown, the limiting protrusion 102 is integrally formed with the base 1, and the limiting protrusion 202 is integrally formed with the wear-resistant block 2.

[0034] The specific usage and function of this embodiment are as follows:

[0035] When the second working surface 204 on the wear-resistant block 2 is worn to a certain extent, we can replace the wear-resistant block 2. Loosen the screw 4, remove the fixing plate 3 at the lower groove 104, and then slide the old wear-resistant block 2 outward through the side close to the lower groove 104.

[0036] Then, the new wear-resistant block 2 can be inserted into the mounting groove 101 through the side near the lower groove 104. The limiting protrusion 102 and the second limiting groove 201 can restrict one side of the wear-resistant block 2. Then, the fixing plate 3 is placed in the upper groove 203 and the lower groove 104. The screw 4 passes through the fixing plate 3 and is screwed into the threaded hole 105. Tighten the screw 4 to fix the fixing plate 3. The fixing plate 3 can restrict the other side of the wear-resistant block 2. At the same time, the limiting protrusion 202 and the first limiting groove 103 can limit the vertical direction of the wear-resistant block 2, which can effectively prevent the wear-resistant block 2 from falling off.

[0037] The perforated guide plate uses a splicing method based on the traditional perforated guide plate, reducing the wear-resistant material at both ends while maintaining the wear-resistant function in the middle. The wear-resistant block 2 in the middle can be disassembled and replaced after wear, while the base 1 can be used for a long time without frequent replacement. This perforated guide plate greatly reduces the cost compared to the traditional perforated guide plate.
