Description

Technical Field

[0001] This application relates to the field of mold installation tools, and in particular to a positioning device for quickly installing molds. Background Technology

[0002] During the processing of seamless steel pipes, a corresponding straightening machine is required to straighten the seamless steel pipes.

[0003] Reference Figure 1 The existing steel pipe straightening machine includes a frame, a guide rail 1, an upper die 3, and a lower die 2. The upper die 3 is connected to the frame via an upper base 4, which slides vertically along the frame. The lower die 2 is connected to the guide rail 1 via a lower base 5, which is connected to rollers 51. The rollers 51 roll along the guide rail 1 and move the lower die 2 closer to or away from the upper die 3. The upper die 3 is detachably connected to the upper base 4. Connecting blocks 31 are fixedly installed at both ends of the top of the upper die 3. The upper base 4 has corresponding mounting slots 42 for installation. The connecting block 31 slides along the length of the steel pipe (usually horizontally) and fits against the inner wall of the mounting groove 42. To fix the upper mold 3, a mounting plate 41 is also provided below the mounting groove 42. The mounting plate 41 is detachably fixed to the upper base 4 by bolts. The top of the mounting plate 41 contacts the bottom of the connecting block 31. When the mounting plate 41 is fastened to the upper base 4 by bolts, it presses the connecting block 31 upward, forcing the connecting block 31 to tightly abut against the inner wall of the mounting groove 42, so that the upper mold 3 is stably connected to the upper base 4.

[0004] Regarding the aforementioned technologies, when installing the upper mold, it is usually necessary to first place the upper mold on top of the lower mold, and then adjust the relative positions of the two by the operator to align the upper mold with the lower mold, and ensure that the connecting block of the upper mold can be accurately aligned with the mounting slot of the upper base. This alignment process mainly relies on manual operation. It is difficult for the operator to complete the alignment and installation of the connecting block with the mounting slot in one go by visual inspection, and repeated attempts are required, which affects work efficiency. Utility Model Content

[0005] To improve the ease of upper mold installation and increase work efficiency, this application provides a positioning device for quick mold installation.

[0006] The positioning device for quick mold installation provided in this application adopts the following technical solution:

[0007] A positioning device for quick mold installation includes a support frame and limiting rods. The support frame is used to connect with the lower mold and slides along the length direction of the steel pipe to fit the top of the upper mold. Two limiting rods are provided, and the two limiting rods are spaced apart to form a gap for the upper mold to be placed. The two limiting rods are respectively used to contact the two ends of the upper mold.

[0008] By adopting the above technical solution, when in use, after placing the support frame on top of the lower mold, the upper mold is placed between the two limiting rods, so that the limiting rods contact the upper mold, and the support frame is moved along the horizontal direction and the length of the steel pipe, thereby driving the upper mold to move to the corresponding position, so that the upper mold and the lower mold are aligned, and the upper mold is aligned with the installation groove, which facilitates the installation of the upper mold and improves work efficiency.

[0009] Optionally, the support frame is connected to a reinforcing rod, with both ends of the reinforcing rod connected to the support frame.

[0010] By adopting the above technical solution and adding reinforcing bars, the overall stability of the support frame can be improved.

[0011] Optionally, the support frame is connected with a tie rod.

[0012] By adopting the above technical solution and adding tie rods, it is easier for operators to move and transport the support frame.

[0013] Optionally, a movable groove is provided at the bottom of the support frame. The movable groove is horizontally arranged, and the length direction of the movable groove is perpendicular to the length direction of the steel pipe. The inner walls at both ends of the width direction of the movable groove are in contact with the two ends of the lower mold, respectively.

[0014] By adopting the above technical solution and adding a moving groove, the movement direction of the support frame is limited, so that the support frame can move stably in the predetermined direction.

[0015] Optionally, the support frame is provided with scale lines at both ends. The scale lines are opened horizontally and perpendicular to the length of the steel pipe. The scale lines are used to align the lower mold.

[0016] By adopting the above technical solution and adding scale lines, it is easier for the support frame to align with the lower mold in a horizontal direction and along the length of the steel pipe, further facilitating the alignment of the upper mold with the lower mold and the alignment of the upper mold with the mounting groove, thus facilitating the installation of the upper mold.

[0017] Optionally, the support frame is connected to a magnetic block, and when the support frame is placed on the lower mold, the magnetic block and the lower mold attract each other.

[0018] By adopting the above technical solution and adding magnetic blocks, the support frame is stably connected to the lower mold during use, minimizing the possibility of the support frame shifting due to external forces.

[0019] Optionally, the support frame is connected to positioning rods, and there are two positioning rods. The two positioning rods are respectively located at both ends of the support frame. The two positioning rods are respectively used to contact the lower mold at both ends that are horizontal and perpendicular to the length direction of the steel pipe. The positioning rods are slidably fitted to the support frame. The support frame is connected to an adjusting component, which is used to drive the positioning rods to move and move the positioning rods closer to or away from the lower mold.

[0020] By adopting the above technical solution, when in use, the support frame is placed on top of the lower mold, and the lower mold is located between the two positioning rods. After the support frame is moved to the corresponding position, the positioning rod is moved by the adjusting component so that the positioning rod is close to the lower mold and pressed against the lower mold, so that the support frame is stably connected to the lower mold. When disassembling the support frame, the adjusting component moves the positioning rod away from the lower mold, so that the support frame can be easily removed from the lower mold.

[0021] Optionally, limit holes are provided at both ends of the support frame, and one end of each positioning rod is slidably fitted into the inner wall of the limit hole. The adjusting component includes a threaded rod and a handle. The threaded rod is rotatably connected to the support frame. The threaded rod includes a positive thread section and a negative thread section. One positioning rod is threaded onto the positive thread section, and the other positioning rod is threaded onto the negative thread section. The handle is threaded to one end of the threaded rod.

[0022] By adopting the above technical solution, when in use, the support frame is placed on top of the lower mold. By turning the threaded rod with the handle, the two positioning rods are moved and brought closer to each other, so that the positioning rods are pressed against the lower mold. When disassembling the support frame, the handle is turned to rotate the threaded rod, so that the two positioning rods are moved away from each other, which facilitates the simultaneous movement of the two positioning rods and facilitates the installation and disassembly of the support frame.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When in use, place the support frame on top of the lower mold, place the upper mold between the two limiting rods, and make the limiting rods contact the upper mold. Move the support frame horizontally and perpendicular to the length of the steel pipe to move the upper mold to the corresponding position, so that the upper mold and the lower mold are aligned, and the upper mold is aligned with the mounting groove, which facilitates the installation of the upper mold and improves work efficiency.

[0025] 2. Add a moving groove to limit the movement direction of the support frame, so that the support frame can move stably in the predetermined direction;

[0026] 3. Adding scale lines makes it easier for the support frame to align with the lower mold horizontally and along the length of the steel pipe, further facilitating the alignment of the upper mold with the lower mold and the upper mold with the mounting groove, thus facilitating the installation of the upper mold.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 2-4 This application will be described in further detail.

[0033] This application discloses a positioning device for quickly installing a mold. Example 1: Refer to... Figure 2 A positioning device for quick mold installation includes a support frame 100 and limiting rods 200. The support frame 100 is used to connect to the lower mold 2, and is horizontally arranged with its length direction perpendicular to the length direction of the steel pipe. Two limiting rods 200 are connected to the top of the support frame 100, and are spaced apart to form a gap for the upper mold 3 to pass through. The two limiting rods 200 are respectively used to contact both ends of the upper mold 3. Placing the support frame 100 on top of the lower mold 2 and positioning the upper mold 3 through it facilitates alignment of the upper mold 3 with the mounting groove, improves the ease of installation of the upper mold 3, reduces the time required for installation, and increases work efficiency.

[0034] Reference Figure 2 The support frame 100 includes mounting rods 110 and support plates 120. The mounting rods 110 are horizontally positioned, with their length direction perpendicular to the length direction of the steel pipe. Two mounting rods 110 are provided, spaced apart along the length direction of the steel pipe, and are used to contact the top of the lower mold 2. Two support plates 120 are provided, with their length direction aligned with the length direction of the mounting rods 110. Each support plate 120 is connected to the bottom of its respective mounting rod 110. The two support plates 120 form a sliding groove 130 that slides and engages with the lower mold 2. The length direction of the sliding groove 130 is aligned with the length direction of the mounting rods 110, and the two support plates 120 are used to contact both ends of the lower mold 2.

[0035] Reference Figure 2The support frame 100 is connected to two reinforcing rods 140. The length of the reinforcing rods 140 is aligned with the width of the support frame 100. The two reinforcing rods 140 are positioned between two limiting rods 200, and their ends are connected to two mounting rods 110, respectively. The support frame 100 is also connected to two tie rods 150. Two tie rods 150 are provided, each positioned at one end of the length of the support frame 100. The length of the tie rods 150 is aligned with the width of the support frame 100, and their ends are connected to the tops of the two mounting rods 110, respectively.

[0036] Reference Figure 2 and Figure 3 The mounting rod 110 has graduation lines 111 at both ends of its length, with the graduation lines 111 extending along the length of the mounting rod 110. Magnetic blocks 112 are embedded at the bottom of both ends of the mounting rod 110. When the mounting rod 110 contacts the top of the lower mold 2, the magnetic blocks 112 and the lower mold 2 attract each other. In use, the support frame 100 is placed on top of the lower mold 2, and the support frame 100 is moved to the corresponding position using the graduation lines 111. This facilitates alignment between the upper mold 3 and the lower mold 2 when the upper mold 3 is placed between the two limiting rods 200.

[0037] The implementation principle of this embodiment is as follows: In use, the support frame 100 is placed on top of the lower mold 2, so that the lower mold 2 is located in the moving groove 130, and the two ends of the lower mold 2 are respectively in contact with the inner walls of the opposite sides of the moving groove 130. The upper mold 3 is placed on top of the support frame 100, and the support frame 100 is moved along the length direction of the support frame 100. The scale line 111 is aligned with the two ends of the lower mold 2, so as to facilitate the movement of the support frame 100 to the corresponding position and drive the upper mold 3 to align with the lower mold 2. This facilitates the alignment of the upper mold 3 with the mounting groove, thereby facilitating the installation of the upper mold 3 and improving work efficiency.

[0038] Example 2:

[0039] The difference between this embodiment and Embodiment 1 is as follows:

[0040] Reference Figure 4 The support frame 100 is connected to two positioning rods 300. The length direction of the positioning rods 300 is consistent with the length direction of the steel pipe. The two positioning rods 300 are located at both ends of the moving groove 130 along its length direction, and the positioning rods 300 are located on the side of the limiting rod 200 away from the upper mold 3. Two limiting holes 160 are opened on the inner walls of both ends of the moving groove 130 along its width direction. The length direction of the limiting holes 160 is consistent with the length direction of the moving groove 130. The two limiting holes 160 opened on the inner wall of one end of the moving groove 130 are respectively located at both ends of the moving groove 130 along its length direction.

[0041] Reference Figure 4The positioning rod 300 passes through two opposing limiting holes 160 at both ends along its length, and slides along the length of the limiting holes 160 to be connected within them. An adjusting component 400 is connected to the support plate 120. The adjusting component 400 includes a threaded rod 410 and a handle 420. The length of the threaded rod 410 is consistent with the length of the support plate 120, and both ends of the threaded rod 410 are rotatably connected to the support plate 120. The threaded rod 410 includes a positive thread section 411 and a negative thread section 412. One positioning rod 300 is threaded onto the positive thread section 411, and the other positioning rod 300 is threaded onto the negative thread section 412. The handle 420 is connected to one end of the threaded rod 410.

[0042] The implementation principle of this embodiment is as follows: In use, the support frame 100 is placed on top of the lower mold 2, and the upper mold 3 is placed above the support frame 100, with the upper mold 3 positioned between the two limiting rods 200. After moving the support frame 100 to the corresponding position, the handle 420 is rotated, thereby driving the threaded rod 410 to rotate, causing the two positioning rods 300 to move along the length direction of the support frame 100 and move closer to each other, so that the two positioning rods 300 respectively abut against both ends of the lower mold 2, thereby making the support frame 100 stably connected to the lower mold 2. After the upper mold 3 is installed, the upper mold 3 is moved away from the lower mold 2, and the threaded rod 410 is rotated, causing the two positioning rods 300 to move away from each other, thereby facilitating the operator to remove the support frame 100 from the lower mold 2.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
