Description

Technical Field

[0001] This utility model relates to the field of pipe end processing technology, specifically a clamping mold structure for a pipe end forming machine. Background Technology

[0002] Pipe end forming machine is a device for processing pipe fittings into various shapes such as flaring, shrinking, tube shrinking, bulging, and rib building. During the forming process, the pipe needs to be placed on the clamping mold, which can clamp and fix the pipe in the forming position of the forming machine. Then, the forming machine achieves precise forming of the pipe end through a series of precise mechanical structures and hydraulic systems.

[0003] Commonly used pipes include straight pipes and right-angle bends. Although most clamping mold structures can clamp and fix straight pipes, they cannot be used to clamp and fix right-angle bends at the same time. This results in a large limitation in the use of traditional clamping mold structures. In addition, the pipe is usually clamped and placed inside the pipe groove of the clamping mold structure. After the pipe end is formed, most clamping mold structures do not make it easy for users to remove the pipe from the pipe groove. Utility Model Content

[0004] The purpose of this invention is to provide a clamping mold structure for a pipe end forming machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A clamping mold structure for a pipe end forming machine, comprising:

[0007] A base, the top surface of which is rotatably connected to a circular plate;

[0008] An L-shaped plate is fixedly connected to a circular plate, and a cylinder is fixedly connected to the top of the L-shaped plate;

[0009] The clamping mold assembly consists of two parts. One clamping mold assembly is fixed to the top surface of the circular plate, and the other clamping mold assembly is fixed to the output end of the cylinder. The clamping mold assembly includes a carrier plate. A positioning mold base is fixedly connected to the top surface of the carrier plate, and a movable mold base is rotatably connected to the top surface of the carrier plate. Rotating the movable mold base can make it perpendicular to the positioning mold base or collinear with it.

[0010] There are two ejection components, which are respectively arranged inside the positioning mold base and the movable mold base at corresponding positions. Each ejection component includes a support column, the bottom of which is fixedly connected to a compression spring, and the top of which is fixedly connected to an arc-shaped plate.

[0011] Furthermore, both the positioning mold base and the movable mold base can be detachably fixed with an arc-shaped block at one end.

[0012] Furthermore, a motor is fixed inside the base, and the output end of the motor is fixedly connected to the circular plate.

[0013] Furthermore, both the positioning mold base and the movable mold base on the circular plate are provided with columnar slots, which are slidably connected to the support column.

[0014] Furthermore, the bottom end of the compression spring is fixedly connected to the bottom surface of the corresponding columnar slot, and the center of both the positioning mold base and the movable mold base on the circular plate is provided with an arc-shaped notch to facilitate the accommodation of the arc-shaped plate.

[0015] Furthermore, the top surface of the carrier plate is provided with a rotating slot, and a support shaft that is rotatably connected to the rotating slot is fixed at one corner of the movable mold base.

[0016] Furthermore, magnets are embedded and fixed on both sides of the movable mold base, and two iron blocks are fixed on the outer side of the carrier plate, with the iron blocks being attracted and fixed to the corresponding magnets.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. A positioning mold base is fixed on the carrier plate. A movable mold base is arranged at one end of the positioning mold base and rotatedly connected to the carrier plate. In the initial state, the movable mold base and the positioning mold base are arranged in the same line. At this time, the straight tube can be placed between the positioning mold base and the movable mold base above the circular plate. The cylinder output end moves another set of movable mold base and positioning mold base downward, so that the multiple mold bases arranged above and below (including the positioning mold base and the movable mold base) can clamp and fix the straight tube, which facilitates the forming processing of the end of the straight tube.

[0019] Rotate the movable mold base by 90 degrees so that it is arranged at a right angle to the positioning mold base. At this time, the right-angle bend can be placed between the positioning mold base and the movable mold base above the circular plate. Similarly, the cylinder output end moves down with another set of right-angled movable and positioning mold bases, so that multiple mold bases arranged vertically can clamp and fix the right-angle bend. This allows the same clamping mold to clamp and fix straight or bent pipes at the same time for pipe end forming, thus expanding the application range of the clamping mold.

[0020] 2. A support column is slidably connected inside the mold base on the circular plate. An arc-shaped plate is fixed to the top of the support column. A compression spring is fixed between the support column and the mold base. When the upper and lower mold bases are combined to clamp and fix the pipe, the compression spring is in a compressed state. The arc-shaped plate is housed inside the arc-shaped notch on the surface of the mold base. After the pipe end forming process is completed, the cylinder output end moves the mold base fixed to it upward, so that the two sets of mold bases arranged above and below no longer clamp and fix the pipe. At this time, under the elastic force of the compression spring, the support column moves upward with the arc-shaped plate, so that the pipe clamped inside the mold base can be automatically ejected from the mold base, making it convenient for the user to take out the pipe in the pipe groove of the mold base.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1, please refer to Figure 1 - Figure 4In this embodiment of the present invention, a clamping mold structure for a pipe end forming machine includes a base 100, a circular plate 110 rotatably connected to the top surface of the base 100, an L-shaped plate 200 fixedly connected to the top surface of the circular plate 110, a cylinder 210 fixedly connected to the top of the L-shaped plate 200, and clamping assemblies 300 provided at the top of the circular plate 110 and the output end of the cylinder 210. The clamping assembly 300 includes a carrier plate 310, and the circular plate 110 and the output end of the cylinder 210 are respectively connected to the... The positioning plate 310 is fixedly connected, and the top surface of the positioning plate 310 is fixedly connected to the positioning mold base 320. One end of the positioning mold base 320 is arranged with a movable mold base 330 that is rotatably connected to the positioning plate 310. Both the positioning mold base 320 and the movable mold base 330 on the circular plate 110 are provided with an ejection assembly 400. The ejection assembly 400 includes a support column 410. The bottom of the support column 410 is fixedly connected to a compression spring 420, and the top of the support column 410 is fixedly connected to an arc plate 430.

[0028] Specifically, by designing the clamping mold as a positioning mold base 320 and a movable mold base 330, the positioning mold base 320 and the movable mold base 330 are initially arranged collinearly, facilitating the clamping and fixing of straight pipes. Rotating the movable mold base 330 by 90 degrees brings the positioning mold base 320 and the movable mold base 330 into a right-angle arrangement, facilitating the clamping and fixing of right-angle bent pipes. This allows the clamping mold to clamp and fix pipes of different shapes for processing by the forming machine, expanding the applicable pipe range of the clamping mold. A support column 410 is slidably connected inside the positioning mold base 320 and the movable mold base 330. After the pipe is formed, the compression spring 420 pushes the support column 410 upwards. The support column 410, through the arc plate 430, carries the pipe away from the pipe grooves of the positioning mold base 320 and the movable mold base 330, making it convenient for the user to remove the processed pipe.

[0029] like Figure 3 As shown in this embodiment, both the positioning mold base 320 and the movable mold base 330 have tube grooves on their top surfaces. The tube grooves can adapt to the shape of the tube so that the tube can be tightly placed on the mold base. A fixing rubber pad can be sleeved inside the tube groove of the mold base, which helps to improve the firmness and strength of the upper and lower mold bases in clamping and fixing the tube.

[0030] like Figure 2 and Figure 3 As shown, in this embodiment, one end of both the positioning mold base 320 and the movable mold base 330 is detachably fixed with an arc-shaped block 350 by screws. During the processing of the pipe end by the forming machine, the arc-shaped block 350 can contact the processing mold head of the forming machine, and play the role of buffering the impact of the processing mold head of the forming machine on the clamping mold. The specific structure of the arc-shaped block 350 is a component of the prior art, and the specific working principle will not be described in detail.

[0031] like Figure 2 As shown, in this embodiment, a motor is fixed inside the base 100, and the output end of the motor is fixedly connected to the circular plate 110. A positioning ring 120 fixedly connected to the base 100 is rotatably sleeved on the outer side of the circular plate 110. The positioning ring 120 enables the motor output end to rotate stably on the base 100 with the circular plate 110.

[0032] In this embodiment, after one end of the pipe is formed, the motor output can rotate the circular plate 110, thereby causing the clamping mold to rotate with the pipe, so that both ends of the pipe can automatically rotate and be cut to the processing position of the forming machine, making it convenient for the forming machine to automatically form both ends of the pipe.

[0033] like Figure 4 As shown, in this embodiment, both the positioning mold base 320 and the movable mold base 330 on the circular plate 110 are provided with columnar slots. The columnar slots are slidably connected to the support column 410. The bottom end of the compression spring 420 is fixedly connected to the bottom surface of the corresponding columnar slot. Both the positioning mold base 320 and the movable mold base 330 on the circular plate 110 are provided with arc-shaped notches in the middle to facilitate the accommodation of the arc plate 430.

[0034] In this embodiment, when the two mold bases arranged vertically (including the positioning mold base 320 and the movable mold base 330) clamp the tube together, the arc plate 430 is stored in the arc notch, and the support column 410 moves down to compress the compression spring 420. When the tube forming process is completed and the two mold bases separate, the elastic force of the compression spring 420 will drive the support column 410 to move the arc plate 430 upward. The upward-moving arc plate 430 can push the tube out of the mold base, making it convenient for the user to take the tube out of the mold base.

[0035] like Figure 3 and Figure 4 As shown, in this embodiment, the top surface of the carrier plate 310 is provided with a rotating slot 311, and a support shaft 332 that is rotatably connected to the rotating slot 311 is fixed at one corner of the movable mold base 330, so that the movable mold base 330 can rotate at one end of the positioning mold base 320 to arrange the two mold bases in a straight line or in a perpendicular arrangement.

[0036] Example 2, based on Example 1, in order to ensure that the movable mold base 330 can be stably fixed in the adjusted position after rotation adjustment.

[0037] like Figure 3As shown, in this embodiment, magnets 331 are embedded and fixed on both sides of one end of the movable mold base 330, and two iron blocks 340 are fixed on the outer side of the carrier plate 310. The iron blocks 340 are attracted and fixed to the corresponding magnets 331. When the movable mold base 330 is rotated to be arranged perpendicularly or collinearly with the positioning mold base 320, the magnets 331 can be attracted and fixed to the corresponding iron blocks 340, which helps to maintain the position of the movable mold base 330 after rotation adjustment.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
