Description

Technical Field

[0001] This utility model relates to joint processing equipment, and more particularly to an integrated crimping and reinforcement machine. Background Technology

[0002] like Figure 1 The connector 1 shown is a cylindrical tube with several outwardly protruding annular protrusions 11 machined on its outer circumferential wall. These annular protrusions 11 can serve as snap-fit ​​parts during assembly. Machining this type of connector 1 using conventional machining methods, such as lathe turning, is cumbersome, and both clamping and machining can easily lead to deformation of the connector 1 and the annular protrusions 11, resulting in low machining efficiency and unreliable connector quality. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a simple, easy-to-operate, and efficient integrated crimping and anchoring machine. The joints and annular protrusions processed by this equipment are not easily deformed, and the joints have high quality and low processing cost.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: the integrated crimping and piercing machine includes: a base; a mounting frame is fixedly installed on the base, the piercing mold is installed on the mounting frame through a driving structure, a piercing mold cavity is formed inward on the rear end face of the piercing mold, and a mold core is fixedly installed in the piercing mold cavity; a crimping mold is fixedly installed on the mounting frame, the crimping mold is located behind the piercing mold, and a crimping mold cavity is formed inward on the front end face of the crimping mold; the piercing mold can move forward relative to the mounting frame away from the crimping mold through the driving structure, so that the piercing mold cavity and the crimping mold cavity are separated, or the piercing mold can move backward relative to the mounting frame through the driving structure to press tightly against the crimping mold, so that the piercing mold cavity and the crimping mold cavity are closed.

[0005] There are many types of drive structures. Here, based on factors such as the requirements of the pier reinforcement and the installation space, a drive cylinder is selected as the drive structure. The cylinder body of the drive cylinder is fixedly installed on the mounting frame, the piston rod of the drive cylinder points to the rear, and the pier reinforcement mold is fixedly connected to the end of the piston rod of the drive cylinder.

[0006] Furthermore, in the aforementioned integrated crimping and reinforcing bar machine, a guide sleeve is fixedly installed on the mounting frame, and the piston rod of the driving cylinder extends into the guide sleeve; a connecting rod is connected to the end of the piston rod of the driving cylinder, a connecting hole is opened on the bottom surface of the reinforcing bar mold cavity, and a mold core tail embedding groove is opened at the rear end of the connecting hole; the rear end of the connecting rod passes through the connecting through hole and is fixedly connected to the mold core, so that the tail of the mold core is embedded in the mold core tail embedding groove.

[0007] There are several options for the connection method between the rear end of the connecting rod and the mold core. For example, it can be fixed by welding, by using a slotted or clipped structure, or by using screws or pins. In this embodiment, considering the reliability and detachability requirements of the connection, the structure for fixing the rear end of the connecting rod to the mold core is designed as follows: a threaded rod is provided at the rear end of the connecting rod, and a threaded hole matching the threaded rod is opened inward on the front end face of the mold core. The mold core is screwed onto the threaded rod through the threaded hole.

[0008] To ensure that the pier reinforcement mold cavity and the clamping mold cavity can be aligned without misalignment and improve the quality of the pier reinforcement, this solution includes an alignment structure between the clamping mold and the pier reinforcement mold to guide the alignment of the pier reinforcement mold cavity and the clamping mold cavity. The alignment structure consists of several forward-protruding alignment blocks on the front end face of the clamping mold and several inward alignment grooves on the rear end face of the pier reinforcement mold, with each alignment block corresponding to one alignment groove. When the pier reinforcement mold moves backward to be pressed against the clamping mold, each alignment block is embedded in the corresponding alignment groove.

[0009] In addition to the above-mentioned structure, the alignment structure can also be as follows: a forward-protruding annular alignment block is provided on the front end face of the pressing mold, and an annular alignment groove is provided inward on the rear end face of the rib-supporting mold. When the rib-supporting mold moves backward to be pressed against the pressing mold, the annular alignment block is embedded in the corresponding annular alignment groove.

[0010] Furthermore, in the aforementioned integrated crimping and reinforcement machine, a number of first reinforcing ribs are provided on the mounting frame to enhance the overall strength of the mounting frame; the oil pump assembly that provides a hydraulic oil circulation circuit for driving the oil cylinder is fixedly installed on the machine frame via a support frame, and a number of second reinforcing ribs are provided on the support frame to enhance the overall strength of the support frame.

[0011] The beneficial effects of this utility model are: the above-mentioned integrated crimping and reinforcement machine has a simple structure, is easy to operate, has high processing efficiency, and the processed joints and annular protrusions are not easily deformed, resulting in good processing quality, which greatly improves the qualification rate of joint processing and reduces costs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] like Figure 2 , Figure 3 and Figure 4As shown, the integrated crimping and piercing machine described in this embodiment includes: a base 2; a mounting frame 4 is fixedly installed on the base 2; a piercing mold 6 is mounted on the mounting frame 4 via a driving structure; a piercing mold cavity 62 is formed inward on the rear end face of the piercing mold 6; and a mold core 61 is fixedly disposed within the piercing mold cavity 62. A crimping mold 7 is fixedly installed on the mounting frame 3; the crimping mold 7 is located behind the piercing mold 6; and a crimping mold cavity 71 is formed inward on the front end face of the crimping mold 7. The piercing mold 6 can move forward relative to the mounting frame 4 away from the crimping mold 7 via the driving structure, causing the piercing mold cavity 62 to separate from the crimping mold cavity 71; or the piercing mold 6 can move backward relative to the mounting frame 4 via the driving structure to press tightly against the crimping mold 7, causing the piercing mold cavity 62 and the crimping mold cavity 71 to close.

[0022] There are many types of drive structures. Here, based on the requirements of the pier reinforcement and the installation space, the drive structure is selected as the drive cylinder 5. The cylinder body of the drive cylinder 5 is fixedly installed on the mounting frame 4. The piston rod 51 of the drive cylinder 5 points to the rear. The pier reinforcement mold 6 is fixedly connected to the end of the piston rod 51 of the drive cylinder.

[0023] A more preferred embodiment is that a guide sleeve 8 is fixedly installed on the mounting bracket 4, and the piston rod 51 of the driving cylinder extends into the guide sleeve 8. A connecting rod 52 is connected to the end of the piston rod 51 of the driving cylinder. A connecting hole is opened on the bottom surface of the rib-forming mold cavity 62, and a mold core tail embedding groove 65 is opened at the rear end of the connecting hole. The rear end of the connecting rod 52 passes through the connecting through hole and is fixedly connected to the mold core 61, so that the tail of the mold core 61 is embedded in the mold core tail embedding groove 65.

[0024] There are several options for the connection method between the rear end of the connecting rod 52 and the mold core 61. For example, it can be fixed by welding, by using a slot and block structure for snap-fit ​​fixing, or by using screws and pins. In this embodiment, considering the reliability of the connection and the requirement for disassembly, the structure for fixing the rear end of the connecting rod 52 and the mold core 61 is designed as follows: a threaded rod 53 is provided at the rear end of the connecting rod 52, and a threaded hole matching the threaded rod 53 is opened inward on the front end face of the mold core 61. The mold core 61 is screwed onto the threaded rod 53 through the threaded hole.

[0025] To ensure that the pier reinforcement mold cavity 62 and the clamping mold cavity 71 can be aligned without misalignment and improve the quality of the pier reinforcement, this embodiment provides an alignment structure between the clamping mold 7 and the pier reinforcement mold 6 to guide the pier reinforcement mold cavity 62 of the pier reinforcement mold 6 to be aligned with the clamping mold cavity 71 of the clamping mold 7. The alignment structure described in this embodiment is as follows: Figure 5As shown, a number of forward-protruding alignment blocks 73 are provided on the front end face of the pressing mold 7, and a number of alignment grooves 64 are provided inward on the rear end face of the reinforcing bar mold 6. Each alignment block 73 corresponds to one alignment groove 64. When the reinforcing bar mold 6 moves backward to be pressed against the pressing mold 7, each alignment block 73 is embedded in the corresponding alignment groove 64.

[0026] In addition to the structures mentioned above, the positive structure can also have the following structures: such as Figure 4 As shown, a forward-protruding annular alignment block 72 is provided on the front end face of the pressing mold 7, and an annular alignment groove 63 is provided inward on the rear end face of the reinforcing rib mold 6. When the reinforcing rib mold 6 moves backward to be pressed against the pressing mold 7, the annular alignment block 72 is embedded in the corresponding annular alignment groove 63.

[0027] In this embodiment, a plurality of first reinforcing ribs are provided on the mounting frame 4 to enhance the overall strength of the mounting frame 4; the oil pump assembly 3, which provides a hydraulic oil circulation circuit for driving the oil cylinder, is fixedly mounted on the frame 2 via a support frame 31, and a plurality of second reinforcing ribs are provided on the support frame 31 to enhance the overall strength of the support frame 31.

[0028] When processing the joint, first place the round tube into the crimping cavity 71 of the crimping mold 7, start the drive cylinder 5, and extend the piston rod 51 of the drive cylinder 5 backward, pushing the rib-forming mold 6 backward until the rib-forming mold 6 presses against the crimping mold 7. At this time, the round tube undergoes plastic deformation, forming an outwardly protruding annular protrusion 11. Then start the drive cylinder 5, and retract the piston rod 51 of the drive cylinder 5 forward, pulling the rib-forming mold 6 forward. At this time, the rib-forming mold 6 separates from the crimping mold 7, and the processed joint can be taken out before processing the next joint.

[0029] The aforementioned integrated crimping and reinforcement machine has a simple structure, is easy to operate, has high processing efficiency, and produces joints and annular protrusions that are not easily deformed, resulting in good processing quality. This greatly improves the qualification rate of joint processing and reduces costs.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any modifications or equivalent changes made based on the technical essence of the present utility model shall still fall within the scope of protection claimed by the present utility model.
