[0001] This invention relates to the field of shipbuilding technology, and in particular to an angle steel pressing tool. Background Technology

[0002] In shipbuilding, structural profiles serve as the weight-bearing skeleton of the ship, and their importance is self-evident. Angle steel, as a common and widely used structural profile in shipbuilding, requires consideration of the angle steel pressing process when joining angle steel of different specifications. Traditional angle steel pressing processes require the use of small machine tools, which is time-consuming, labor-intensive, and requires consideration of factors such as space availability, resulting in high processing costs. Summary of the Invention

[0003] In view of this, the present invention provides an angle steel pressing head tool to solve the problem that the existing technology requires the use of a specific machine tool for angle steel pressing head operation, which is time-consuming, labor-intensive and has high processing costs.

[0004] An angle steel pressing tool includes a main structure with a web receiving groove for placing the web of the angle steel. A push-fixing member is threadedly connected to one side wall of the web receiving groove, which is used to push and fix the web against the groove side wall on the other side. The main structure also includes a pressure plate located at the upper end of the web receiving groove and spaced apart from the web receiving groove. A pressure block structure is threadedly connected to the pressure plate for moving towards the web receiving groove, and the pressure block structure is used to press the face of the angle steel.

[0005] Furthermore, the main structure includes a web plate main body and a panel main body that are separately arranged, wherein the pressure plate is disposed on the panel main body, the web plate receiving groove is disposed on the web plate main body, and the web plate main body and the panel main body are detachably and fixedly connected together.

[0006] Furthermore, the panel body has an L-shaped cross-section. The L-shaped panel body includes a vertically arranged pressure plate and an insertion edge. The web body is provided with a fixing groove for accommodating the insertion edge. The fixing groove is arranged parallel to and spaced apart from the web accommodating groove.

[0007] Furthermore, the insertion edge is provided with a plurality of first through holes arranged at intervals, and the side of the fixing groove away from the web receiving groove is provided with a plurality of second through holes corresponding to the first through holes. The distance between the pressure plate and the web body is changed by inserting pins into the first through holes and second through holes at different positions.

[0008] Furthermore, the pressure block structure includes an integrally connected pressure head and pressure rod, the pressure rod is provided with a first threaded section for threaded connection with the pressure plate, and a first handle is also fixedly provided on the pressure rod.

[0009] Furthermore, the abutment fixing member includes an abutment head and an abutment rod. The abutment rod is provided with a second threaded section for threaded connection with the web body member, and a second handle is also fixedly provided on the abutment rod.

[0010] Furthermore, a rubber block is provided on the outer peripheral surface of the abutment head, and the rubber block is used to directly contact the web plate.

[0011] Furthermore, the angle steel pressing tool also includes a pressure equalization structure for setting at the junction of the web and face plate notches.

[0012] The beneficial effects of the angle steel pressing tool in this invention are as follows: The angle steel pressing tool in this invention facilitates the accommodating of the web of the angle steel by setting a web receiving groove on the main structure, and also limits the angle steel's position; by setting a stop fixing component, which is threadedly connected to the main structure, it facilitates the stop of the web, thereby limiting and fixing the angle steel; by setting a pressure plate and a pressure block structure threadedly connected to the pressure plate, it facilitates the application of pressure to the panel, thus facilitating the pressing process. Since both the pressure block structure and the stop fixing component are threadedly connected to the main structure, operation is convenient. The thread and pressure block structure can amplify the lever arm, thus eliminating the need for additional machine tools. This solves the problem in the prior art that angle steel pressing operations require specific machine tools, which is time-consuming, labor-intensive, and have high processing costs.

[0022] To better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.

[0023] In Embodiment 1 of the angle steel pressure head tool of this invention: like Figure 1 and Figure 2 As shown, the angle steel 6 pressing head 41 tool in this embodiment includes a main structure, which is divided into two parts: a web plate main body 2 for placing the web plate of the angle steel 6 and a panel main body 1. The web plate main body 2 is provided with a web plate receiving groove 21 for placing the web plate, and also with a fixing groove for installing the panel main body 1. The web plate receiving groove 21 and the fixing groove are arranged parallel and spaced apart. Furthermore, to fix the angle steel 6, the web plate main body 2 is also provided with a backing fixing member 3 that connects to the web plate receiving groove 21 for easy clamping of the web plate, and a pressing block structure 4 for pressing down the panel.

[0024] Specifically, such as Figure 3 and Figure 4As shown, the web plate main body 2 is U-shaped, with two vertically arranged sides and a bottom edge. The sides and bottom edge define a web plate receiving groove 21. The width of the web plate receiving groove 21 is greater than the thickness of the web plate in the angle steel 6, facilitating movement of the web plate within the groove. A second threaded hole 22, connecting to the web plate receiving groove 21, is provided on one side of the web plate main body 2. This second threaded hole 22 is used to install a backing fastener 3. On the other side of the web plate main body 2, a fixing groove for fixing the panel main body 1 is also provided along its length. The fixing groove and the web plate receiving groove 21 are arranged parallel and spaced apart. On the side of the fixing groove away from the web plate receiving groove 21, a second through hole for inserting a pin is also provided. Two rows of the second through holes are arranged at intervals along the height direction. In this embodiment, there are six second through holes, arranged in two rows with three different heights. Of course, in other embodiments, other numbers can be used.

[0025] The panel body 1 is used for insertion and fixation in the fixing groove. The panel body 1 is generally L-shaped, with a long side and a short side. The short side forms a pressure plate 11, and the long side forms an insertion edge 12 for insertion and fixation in the fixing groove. The pressure plate 11 is provided with a first threaded hole 13, and a pressure block structure 4 for pressing the panel of the angle steel 6 is installed in the first threaded hole 13. The pressure plate 11 is also arranged at intervals with the web receiving groove 21 for the angle steel 6 to enter and exit. The insertion edge 12 is provided with a first through hole that corresponds one-to-one with the second through hole. In this embodiment, there are also six first through holes, and the positions of the six first through holes can be arranged one-to-one with the second through holes. In order to achieve a fixed connection between the panel body 1 and the web body 2, the angle steel 6 pressing head 41 tool also includes a pin for simultaneously inserting into the first through hole and the second through hole. It is worth noting that during use, it is not necessary to strictly align all the first and second through holes. For example, aligning the four first through holes at the bottom of the panel body 1 with the four second through holes at the top of the web body 2 can also achieve the connection between the two. In this case, the height of the panel body 1 will be increased relative to the height of the web body 2, which facilitates the processing of angle steel 6 with larger web dimensions. The two rows and three columns of through holes allow for three overlap heights between the panel body 1 and the web body 2. The two-column configuration ensures that the panel body 1 can be effectively fixed even when it is at the top, preventing rotation.

[0026] like Figure 7As shown, the abutment fixing component 3 includes an abutment head 34 and an abutment rod 32. The abutment head 34 is a block-shaped structure integrally formed at the end of the abutment rod 32, and its size is larger than that of the abutment rod 32 to increase the contact area. To avoid damage to the web of the angle steel 6, a rubber block for direct contact with the web of the angle steel 6 is wrapped around the outer circumferential surface of the abutment head 34. Of course, in other embodiments, the rubber block may only be bonded to the side of the abutment head 34 for contact with the web. To facilitate the abutment fixing of the web, a second threaded section 33 for threaded assembly with the second threaded hole 22 is also provided on the abutment rod 32. A second handle 31 with its axial direction perpendicular to the axial direction of the abutment rod 32 is also provided on the abutment rod 32. The second handle 31 is used to drive the abutment rod 32 to rotate, thereby causing the abutment head 34 to move forward or backward under the action of the second threaded section 33 and the second threaded hole 22, thus enabling the abutment to tighten and loosen against the web of the angle steel 6.

[0027] like Figure 5 and Figure 6 As shown, the pressure block structure 4 includes an integrally connected pressure head 41 and pressure rod 42. The size of the pressure block is larger than that of the pressure rod 42 to increase the force-bearing area. The pressure block needs to act on the panel of the angle steel 6. To protect the panel, a first rubber block 45 is also wrapped around the pressure block. Of course, in other embodiments, only one rubber pad can be provided. To facilitate the pressing of the panel of the angle steel 6, a first threaded section 43 for matching the first threaded hole 13 is provided on the pressure rod 42. A first handle 44 is also provided on the pressure rod 42. The axial direction of the first handle 44 is perpendicular to the axial direction of the pressure rod 42. When the first handle 44 drives the pressure rod 42 to rotate, the pressure head 41 can be raised or lowered by the action of the first threaded section 43 and the first threaded hole 13.

[0028] like Figure 8 As shown, during the pressing head 41 process of angle steel 6, there is a gap 61 between the face plate and the web plate. If the face plate is directly pressed, a lever support point will be formed at the junction of the gap 61 between the face plate and the web plate, resulting in excessive local stress and easy deformation. In this embodiment, the pressing head 41 tool for angle steel 6 also includes a pressure equalization structure 5 for setting at the junction of the gap 61 between the web plate and the face plate. The pressure equalization structure 5 includes a pressure equalization body 51, a third threaded section is provided on the pressure equalization body 51, a washer 54 and a wing nut 53 are provided on the third threaded section, and a limiting plate 52 is also provided at the end of the pressure equalization body 51 away from the third threaded section. The limiting plate 52 and the wing nut 53 can make the pressure equalization structure 5 clamp on both sides of the web plate of angle steel 6, so that the pressure equalization structure 5 can play a certain supporting role for the face plate, increase the contact area, and thus avoid excessive local stress in the structure at this point.

[0029] Specifically, in use, first, keep the panel body 1 and the web body 2 independent of each other. Install the abutment fixing member 3 onto the web body 2, and install the pressure block structure 4 onto the panel body 1. Then, place the angle steel 6 onto the web body 2, keeping the web fixed by the abutment fixing member 3. Next, fix the panel body 1 onto the web body 2. During the fixing process, adjust the position according to the specific dimensions of the angle steel 6 so that the pressure block structure 4 is as close to the panel as possible after installation, thereby reducing the amount of movement of the pressure block structure 4 and completing the connection between the panel body 1 and the web body 2. At the same time, the pressure equalizing structure 5 should also be installed at the notch 61 position of the angle steel 6. The installation of the pressure equalizing structure 5 can be done before pressing the panel, or it can be done before placing the angle steel 6 onto the tool. Finally, press the panel by rotating the first handle 44, causing the pressure head 41 to press the panel to move.

[0030] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
