Description

Technical Field

[0001] The utility model relates to the technical field of hose clamp assembly equipment, in particular to a full-automatic hose clamp machine. Background Art

[0002] Hose clamps (rubber tube clamps) are widely used in the fields of automobiles, tractors, locomotives, ships, mines, petroleum, chemical industry, pharmaceuticals, agriculture, etc. They can tightly clamp flexible hoses on rigid parts and are used for sealing in the fields of water, oil, steam, dust, etc. They are ideal connecting fasteners. A hose clamp generally consists of a band, a head and a screw. Hose clamps are mainly divided into three types: British, American and German. In addition, there are also other derivative products such as tube bundles and European standard hose clamps.

[0003] A hose clamp machine generally refers to equipment used for assembling and processing hose clamp forming. During the processing, the band is first inserted into the head, and then pressed and connected through a riveting mechanism so that the head is fixed at one end of the band. Subsequently, after the band is curled, a screw is assembled and tightened. At present, the tooling structure of some hose clamp machines is relatively simple. When the head and the band are riveted and joined, the head is generally placed in a simple tooling groove and cooperates with a corresponding riveting punch to complete the riveting combination. In this process, the structure of the tooling groove is fixed. In order to ensure that the head can stably enter and exit the tooling groove before and after riveting, there is a gap between the inner wall of the tooling groove and the head. This gap will cause a certain degree of uncertainty in the deformation of the head after riveting, and it is easy to occur joint offset and dislocation. In addition, the head is easily stuck in the tooling groove due to deformation after riveting, and it is relatively difficult for the subsequent clamping structure to pick it up. Summary of the Utility Model

[0004] The utility model provides a full-automatic hose clamp machine, which is beneficial to solving the problems that the head of the hose clamp is easily misaligned during riveting and difficult to exit the groove caused by the fixed structure of the riveting tooling groove of some existing hose clamp machines.

[0005] The utility model is implemented as follows:

[0006] A fully automatic hose clamp machine includes a frame. On the frame, there are a first turntable and a second turntable arranged front and back. Around the first turntable, there are a hose head feeding mechanism, a hose band feeding mechanism, and a riveting and pressing mechanism. Between the second turntable and the first turntable, there are a curling mechanism and a transfer mechanism. Around the second turntable, there are a screw feeding mechanism, a screw locking mechanism, and a discharging mechanism. On the first turntable, there are several tooling mechanisms arranged centrosymmetrically. On the tooling mechanism, there are a first slider and a second slider arranged collinearly inside and outside along the radial direction of the first turntable. Between the first slider and the second slider, there is a tooling gap adapted to the hose head. On both sides of the tooling gap, there are third sliders that can move horizontally left and right. The riveting and pressing mechanism has a punch that can move up and down. On the punch, there is a riveting head for riveting the hose head and the hose band. Around the riveting head, there are push rods corresponding to the first slider, the second slider, and the third slider respectively. After the punch descends at the riveting station, before the riveting head completes the riveting action, each push rod can cooperate to control the first slider, the second slider, and the third slider to move closer to each other, forming a limiting structure for the tooling gap. The first slider, the second slider, and the third slider are also provided with a mutual separation control structure.

[0007] On the basis of the above technical solution, the tooling mechanism includes a connecting seat for connecting the first turntable. The outer end of the connecting seat is connected with a lifting seat that can move up and down. The outer end of the lifting seat is connected with a tooling table. On the tooling table, there are a first chute and a second chute that are perpendicular and staggered. The first chute is parallel to the radial direction of the first turntable. The first slider and the second slider are linearly slidably arranged in the first chute, and the third slider is linearly slidably arranged in the second chute.

[0008] On the basis of the above technical solution, guide wheels adapted to the push rods are arranged on both the left and right sides of the first slider and the second slider.

[0009] On the basis of the above technical solution, a spring is arranged between the bottom of the lifting seat and the connecting seat.

[0010] On the basis of the above technical solution, tension springs are arranged between the left and right sides of the lifting seat and the connecting seat. The tension springs and the spring can drive the lifting seat to complete the longitudinal reset movement.

[0011] On the basis of the above technical solution, a reset control member is arranged between the outer ends of the third slider in the left and right directions and the tooling table.

[0012] On the basis of the above technical solution, the riveting and pressing mechanism includes a base connected to the frame. On the base, there is a riveting cylinder, and the telescopic rod of the riveting cylinder is vertically downward and connected to the punch.

[0013] On the basis of the above technical solution, a bearing table is further arranged below the punch of the riveting and pressing mechanism. The bottom end face of the tooling table can abut against the bearing table during riveting.

[0014] On the basis of the above technical solution, a pushing inclined surface is provided at the bottom of the pushing rod.

[0015] Compared with the prior art, the utility model has at least the following advantages:

[0016] In the utility model, a first slider, a second slider and a third slider are provided on the tooling mechanism, and the gap at the inner end of the slider is used as the tooling gap for the riveting operation of the ferrule head and the ferrule band. The pushing rod and the mutually separating control structure are used to make the tooling gap an openable and closable tooling groove structure. In this way, the positions of the ferrule head and the steel band can be accurately and reliably constrained during each riveting, reducing the occurrence of offset, misalignment and deformation of the ferrule head after riveting. In addition, by using the controllable gap size, the feeding and discharging before and after riveting are more convenient and smooth, and there will be no material jamming.

[0028] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Combined with Figures 1-6 , this embodiment discloses a fully automatic hose clamp machine, which includes a frame 100 assembled by aluminum alloy profiles and aluminum alloy panels. The frame 100 mainly plays a role of bearing and supporting, serving as the main structure of the equipment. Inside the frame 100, a driving motor, a pneumatic equipment, an electric control system, etc. are installed.

[0030] On the frame 100, a first turntable a and a second turntable b are arranged front and back.

Those skilled in the art can select and implement from the prior arts according to the actual operation situation.

[0032] Combined with Figure 2 , in this embodiment, a hose clamp band discharging end 310 is provided at the output end of the hose clamp band feeding mechanism 300. The hose clamp band discharging end 310 specifically adopts a linear vibrator, which can output a number of horizontal hose clamp bands in a columnar manner one by one. A first clamping jaw 320 and a second clamping jaw 340 are further arranged at the rear end of the hose clamp band discharging end 310. A relay device 330 fixed on the frame 100 is arranged between the first clamping jaw 320 and the second clamping jaw 340. The relay device 330 has a relay working station groove 331. Both the first clamping jaw 320 and the second clamping jaw 340 are pneumatic clamping jaws, and are configured with a rotary cylinder, a transverse movement cylinder and a transverse movement track.

[0033] Combined with Figure 3 As shown, there are 8 tooling mechanisms c arranged centrally symmetrically on the first turntable a. The tooling mechanism c is used to hold the hoop and the hoop head before and after riveting.

[0034] Specifically, the tooling mechanism c is provided with a first slider 4 and a second slider 5 arranged collinearly inside and outside in the radial direction of the first turntable a. A tooling gap for fitting the hoop head is formed between the first slider 4 and the second slider 5. Third sliders 7 capable of lateral movement are provided on both left and right sides of the tooling gap. The riveting mechanism 400 has a punch 430 capable of vertical movement. A riveting head 431 for riveting the hoop head and the hoop is provided on the punch 430. Pushing rods corresponding to the first slider 4, the second slider 5, and the third slider 7 are provided on the periphery of the riveting head 431. After the punch 430 descends to the riveting station, each pushing rod can cooperate to control the first slider 4, the second slider 5, and the third slider 7 to move closer to each other before the riveting head 431 completes the riveting action, forming a limiting structure for the tooling gap. The first slider 4, the second slider 5, and the third slider 7 are also provided with a mutually separating control structure.

[0035] As Figure 4 shown, the riveting mechanism 400 includes a base 410 connected to the frame 100. A riveting cylinder 420 is provided on the base 410. The telescopic rod of the riveting cylinder 420 is vertically downward and connected to the punch 430. The punch 430 has a riveting head 431 located at the central position. First pushing rods 432 are provided on both inner and outer sides in the horizontal direction of the riveting head 431. The first pushing rods 432 correspond to the first slider 4 and the second slider 5. Second pushing rods 432 are provided on both left and right sides in the horizontal direction of the riveting head 431. The second pushing rods 432 correspond to the third slider 7.

[0036] Furthermore, a carrier 440 is provided below the punch 430 of the riveting mechanism 400. The bottom end face of the tooling table 3 can abut against the carrier 440 during riveting, and the carrier 440 can provide a more stable riveting support.

[0037] Combined with Figure 5As shown, the tooling mechanism c includes a connecting seat 1 with a "T" - shaped structure. The inner end of the connecting seat 1 is used to connect the first turntable a, and the outer end of the connecting seat 1 is connected with a lifting seat 2 that can move up and down. A longitudinal guiding track is provided between the lifting seat 2 and the connecting seat 1. The outer end of the lifting seat 2 is connected with a tooling table 3, and the tooling table 3 is horizontally arranged. On the tooling table 3, there are a first sliding groove t1 and a second sliding groove t2 that vertically intersect transversely. The first sliding groove t1 is parallel to the radial direction of the first turntable a. A first slider 4 and a second slider 5 are linearly slidably arranged in the first sliding groove t1, and a third slider 7 is linearly slidably arranged in the second sliding groove t2. Among them, the first slider 4 and the second slider 5 are configured with guide rods and can stably slide in and out along the first sliding groove t1. And a clamping structure adapted to the profile of the ferrule head and the ferrule belt is provided on the adjacent sides of the first slider 4 and the second slider 5. The second slider 5 has a "U" - shaped structure for the ferrule belt to penetrate when feeding.

[0038] Further, guide wheels 6 adapted to the first push rod 432 are provided on the left and right sides of the first slider 4 and the second slider 5. A reset control member is provided between the outer ends of the third slider 7 in the left - right direction and the tooling table 3, specifically a tension spring structure arranged left and right. After the second push rod 432 disengages from the third slider 7, the third slider 7 can move outward left and right in a "Z" - shape. While the outward movement of the inner and outer sides of the first slider 4 and the second slider 5 needs to rely on a push - top cylinder e on the frame 100 (refer to Figure 3 ). At the feeding end, the transverse push cylinder d is used to make the first slider 4 move outward in the first time, for controlling the single - side positioning effect of the ferrule head feeding, facilitating the smooth completion of the subsequent cooperation action with the push rod.

[0039] Further, as Figure 5 shown, a spring 21 is provided between the bottom of the lifting seat 2 and the connecting seat 1. Pulling springs 22 are provided between the left and right sides of the lifting seat 2 and the connecting seat 1. The pulling springs 22 and the spring 21 can drive the lifting seat 2 to complete the longitudinal reset movement. During actual work, when the tooling table 3 enters the riveting station, the bottom of the tooling table 3 is in a separated state from the bearing table 440. After the punch 430 moves downward, it can drive the tooling table 3 to move downward to compress the spring 21 and stretch the pulling springs 22. At this time, the bottom end face of the tooling table 3 abuts against the bearing table 440 for riveting operation. Subsequently, the punch 430 moves upward, and the tooling table 3 without the downward pressing force resets upward by means of the spring 21 and the pulling springs 22.

[0040] In order to enable the slider to slide smoothly, a pushing inclined surface is provided at the bottom of the pushing rod. After the first pushing rod 432 moves downward, its pushing inclined surface contacts the guide wheel 6. By utilizing the relative movement and the rotation of the guide wheel 6, the downward pressing force is converted into a lateral thrust. After the second pushing rod 432 moves downward, its pushing inclined surface contacts the outer corner at the top of the third slider 7. It should be noted that the outer corner at the top of the third slider 7 has a suitable chamfer structure, which can also convert the downward pressing force into a lateral thrust. Therefore, the gap at the inner end of the slider is used as the tooling gap for the riveting operation of the ferrule head and the ferrule band. In cooperation with the pushing rod and the mutually separating control structure, this tooling gap is an openable and closable tooling groove structure. This method enables the accurate and reliable position constraint of the ferrule head and the steel band during each riveting, reducing the occurrence of offset, dislocation, and deformation of the ferrule head after riveting. Additionally, by utilizing the controllable gap size, the feeding and discharging before and after riveting are more convenient and smooth, and there will be no material jamming situation.

[0041] During actual operation, the ferrule head feeding mechanism 200 transports the ferrule heads to the tooling mechanism c one by one. Subsequently, the ferrule band feeding mechanism 300 transports and inputs the ferrule band into the ferrule head on the tooling mechanism c at the threshold station. Then, the riveting mechanism 400 performs riveting treatment on it. Subsequently, the transfer mechanism 600 transfers the riveted semi-finished product to the curling mechanism 500 for curling. Then, the transfer mechanism 600 transfers the curled ferrule band to the tooling plate on the second turntable b. The screw feeding mechanism 700 inputs screws, and the screw locking mechanism 800 performs screw locking. Finally, the finished product is output through the discharging mechanism 900.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
