Description

Technical Field

[0001] The utility model relates to the technical field of automobile cable processing equipment, in particular to a deburring device for automobile cable joints. Background Art

[0002] Automobile cables are generally composed of a steel wire rope, a hose, cable joints at both ends of the steel wire rope, pipe sleeves at both ends of the hose, and a sponge sleeve at the installation section. Among them, the processing or manufacturing process of the cable joint requires processes such as cutting, punching, casting, deburring, and length detection. In recent years, some technicians have designed an all-in-one machine, such as a processing equipment designed by the applicant's technicians, which arranges multiple processing devices for straightening, cutting, punching, length detection, casting, and deburring in parallel, and moves the cable for processing the cable joint laterally through a cable parallel transmission device, such as clamping, horizontally shifting, and loosening the front end of the steel wire rope, while clamping, horizontally shifting, and loosening the sponge sleeve and hose at the middle and rear ends. In addition, the cable joint displacement structure in the cable parallel transmission device that moves the steel wire rope from the casting device position to the deburring device position also has the function of horizontally moving the burr blocks left on the top surface of the lower fixed mold to the burr block collection area. This processing equipment greatly improves production efficiency and reduces labor costs.

[0003] The cable joint deburring device in the processing equipment includes a stamping cylinder electrically connected to the controller, an upper punch and a lower fixed die with a stamping through hole. The cable joint after stamping falls together with the cable, and the burr blocks punched out remain on the top surface of the lower fixed die. At this time, the falling cable is horizontally moved to the cable collection area by the cable parallel transmission device of the processing equipment. At the same time, the burr blocks remaining on the top surface of the lower fixed die are horizontally picked up by the cable joint displacement structure to the burr block collection area.

[0004] However, in production practice, the above and other prior art deburring devices still have the following shortcomings: the punching cylinder drives the upper punch to punch once, which sometimes damages the cable joint, such as cutting the upper or lower corners of the two end faces of the hammer-shaped cable joint, resulting in some cable joints being of unqualified quality after deburring. Utility Model Content

[0005] The utility model aims to solve the technical problem of providing a deburring device for an automobile cable joint, which can enable a punch and a lower fixed die to accurately remove burrs and prevent the cable joint itself from being damaged.

[0006] The technical solution of the utility model is to provide a deburring device for an automobile cable joint, comprising a stamping cylinder electrically connected to a controller, an upper punch connected to the free end of the piston rod of the stamping cylinder, and a lower fixed die with a stamping through hole; further comprising a pressing cylinder with a lower end connected to the upper end of the stamping cylinder, the pressing cylinder being electrically connected to the controller; further comprising a sensor which sends an electrical signal to the controller when the bottom end of the upper punch abuts against the cable joint, so that the controller controls the stamping of the stamping cylinder.

[0007] After adopting the above structure, the deburring device of the automobile cable joint of the utility model has the following advantages: since the stamping cylinder adopts the pressing cylinder and the stamping cylinder which press first and then punch, during stamping, the bottom end face of the punch first presses the top surface of the cable joint, so that the cable joint and the punching through hole are pressed vertically, and then the stamping accurately cuts off the burrs or flash, thereby preventing damage to the cable joint body and ensuring that the quality of the cable joint after deburring is qualified.

[0008] Furthermore, the deburring device for the automobile cable joint of the present invention also includes an air nozzle for blowing air for cooling the cable joint placed on the stamping through hole and the upper punch during stamping; the stamping through hole is a T-shaped through hole that matches the shape of the T-shaped cable joint; a horizontal wall and two vertical walls of the T-shaped stamping through hole of the lower fixed die both protrude upward and extend toward the top surface to form a boss for pre-tightening burrs. After adopting the boss structure, with the cooperation of the air nozzle, since the boss is higher than the rest of the top surface of the lower fixed mold and has a relatively small area, after each cable joint is stamped, the nozzle will blow away the small burrs that may be left on the boss surface, ensuring that the cable joint and the top surface of the stamped through hole are well fitted before stamping. Since the boss area is small, the heat dissipation of this part is relatively small, and the cable joint coming from the casting process and the punch at the boss and stamping can all be cooled in the first time, so that the punch can always maintain good stamping and cutting ability, further ensuring the technical effect of accurately cutting off burrs, preventing damage to the cable joint body, and ensuring the quality of the cable joint after deburring is qualified.

[0009] Furthermore, the height of the punching cylinder is three times the height of the pressing cylinder. With the above structure, the instantaneous punching force of the punching cylinder is stronger and the deburring effect is better.

[0010] Furthermore, the sensor is an electromagnetic induction switch that conducts when aligned horizontally with the magnetic ring on the piston of the compression cylinder or the piston of the punching cylinder. This structure allows the use of the existing piston magnetic ring, simplifying sensor installation and providing sensitive, accurate, and rapid sensing.

[0011] Furthermore, the upper punch is a T-shaped punch that matches the shape of the T-shaped cable connector. The bottom surface of the horizontal plate of the T-shaped punch has a first arc-shaped groove that matches the arc surface of the horizontal head of the cable connector, and the bottom surface of the vertical plate of the T-shaped punch has a second arc-shaped groove that matches the arc surface of the wire rope of the cable connector. With the above structure, the punching holes of the punch and the lower fixed die match the shape of the product. In particular, the bottom ends of the horizontal plate and the vertical plate of the T-shaped punch are both arc-shaped grooves, changing the surface contact cutting to line contact cutting, achieving a better deburring effect, further ensuring the technical effect of accurately cutting off burrs, preventing damage to the cable connector body, and ensuring that the quality of the cable connector after deburring is qualified.

[0020] The following further describes the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these specific embodiments are intended to facilitate understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various specific embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0021] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown.

[0022] The conventional automotive cable 1 comprises a cable connector 11 comprising a generally cylindrical transverse head 111 formed by cutting to length, punching, casting, and deburring, and one end 112 of a steel wire rope fixed at a 90-degree angle thereto, a hose 12 fitted over the wire rope, a sleeve 13 fitted over one end of the hose 12, and a sponge cover 14 fitted over the automotive component mounting portion of the hose 12. The cable connector 11 is generally hammer-shaped, or T-shaped, when viewed from above.

[0023] The deburring device for automobile cable joints of the preferred embodiment is applied to a cable processing equipment 3 designed by the present applicant, wherein multiple processing devices for straightening, cutting, i.e., cutting the wire rope to expose the length, beating, length detection, casting and deburring of the automobile cable 1 are arranged in parallel, and the automobile cable 1 to be processed with the cable joint 11 is moved laterally via the cable parallel transmission device, wherein the cable joint shifting structure 31 in the cable parallel transmission device, which moves one end 112 of the wire rope from the casting device 34 position to the deburring device 2 position, also has the function of horizontally scraping the burr blocks left on the top surface 213 of the lower fixed mold 21 to the burr block collection area.

[0024] The deburring device for automobile cable joints of this preferred embodiment includes a stamping cylinder 25 electrically connected to a controller 32, an upper punch 22 connected to the free end of the piston rod of the stamping cylinder, and a lower fixed die 21 with a stamping through-hole 211. The deburring device 2 also includes a base 23, which is fixed to the work table 331 of the frame 33 of the cable processing equipment 3 described above. The lower fixed die 21 is fixed to the base 23. Below the lower fixed die 21 is a drop point 231 for the punched cable joint 11. A notch 232 or opening is left on the side of the drop point 231 away from the casting device 34 of the cable processing equipment 3 described above for the cable joint 11 to move horizontally to the collection point.

[0025] The above is the prior art. The invention of the deburring device for automobile cable connector of the utility model is as follows.

[0026] The deburring device for an automotive cable connector of the present invention further includes a pressing cylinder 24 whose lower end is connected to the upper end of a pressing cylinder 25. The pressing cylinder 24 is electrically connected to a controller 32. The deburring device for an automotive cable connector of the present invention further includes a sensor that sends an electrical signal to the controller 32 when the bottom end of the upper punch 22 abuts the cable connector 11, thereby causing the controller 32 to control the pressing cylinder 25 to press. It is readily understood that the pressing cylinder 24 first drives the pressing cylinder 25 downward until the bottom end of the upper punch 22 abuts the cable connector 11. At this point, the sensor sends an electrical signal to the controller 32, which then controls the pressing cylinder 25 to press.

[0027] The sensor can be an electromagnetic induction switch 26 that is electrically connected to the magnetic ring on the piston of the compression cylinder 24 or the magnetic ring on the piston of the punching cylinder 25 when they are at the same horizontal position. It is not difficult to connect, and the electromagnetic induction switch 26 is electrically connected to the controller 32.

[0028] One embodiment of the pressing cylinder 24 and the punching cylinder 25 is to use a commercially available integrated cylinder, such as the SDA cylinder sold by Airtac. The upper end is the pressing cylinder 24, and the lower end is the punching cylinder 25. The height of the punching cylinder 25 can be three times the height of the pressing cylinder 24. The sensor can be a commercially available electromagnetic induction switch 26, that is, the sensor can be an electromagnetic induction switch 26 that is turned on when it is at the same horizontal position as the magnetic ring on the piston of the punching cylinder 25. Figure 3 An electromagnetic induction switch 26 is fixed to the outside of the lower portion of the punch cylinder 25. The horizontal position of the electromagnetic induction switch 26 is at the same level as the magnetic ring of the punch cylinder 25's piston when the bottom end of the upper punch 22 abuts the cable connector 11. It is easy to understand that the punch cylinder 25 has an aluminum alloy shell, and the piston's magnetic ring can pass through the aluminum alloy shell and magnetically connect with the electromagnetic induction switch 26, i.e., magnetic induction. Of course, the electromagnetic induction switch 26 can also be fixed to the clamping cylinder 24 and at the same horizontal position as the piston's magnetic ring. The aluminum alloy shell of the clamping cylinder 24 can also magnetically connect the piston's magnetic ring and the electromagnetic induction switch 26. The controller 32 controls the piston of the top compression cylinder 24 to press down first. At this point, the punching cylinder 25 itself is not inflated, but the piston of the compression cylinder 24 drives the piston of the punching cylinder 25 downward. When the bottom end of the upper punch 22 reaches the cable connector 11, the electromagnetic induction switch 26 sends an electrical signal to the controller 32, which then controls the pistons of the punching cylinder 25 to move rapidly simultaneously, thereby punching. When returning to its original position, the controller 32 activates the piston of the punching cylinder 25 to return, pushing the piston of the compression cylinder 24 back to its original position.

[0029] The deburring device for automotive cable connectors in this preferred embodiment also includes an air nozzle for blowing cooling air toward the cable connector 11 resting on the punch hole 211 and the upper punch 22 during punching. It will be appreciated that the air nozzle is connected to an air source, such as the air pump of the cable processing equipment 3 described above, and is switched on and off by a solenoid valve electrically connected to the controller 32. The punch hole 211 is a T-shaped through-hole that matches the shape of the cable connector 11. The lower fixed die 21 has one horizontal wall and two vertical walls that protrude upward and extend toward the top surface, forming a boss 212 for pre-compressing burrs.

[0030] The upper punch 22 is a T-shaped punch that matches the shape of the T-shaped cable joint 11. The bottom surface of the horizontal plate of the T-shaped punch has a first arc-shaped groove 221 that matches the top arc surface of the horizontal head 111 of the cable joint 11, and the bottom surface of the longitudinal plate of the T-shaped punch has a second arc-shaped groove 222 that matches the top arc surface of one end 12 of the steel wire rope of the cable joint 11.

[0031] Deburring is also called deflashing. The controller 32 can be a PLC controller. The upper punch 22 is also called the upper movable die, and the lower fixed die 21 with the punched through hole 211 is also called the female die. The air nozzle is not shown in the figure. The wires and air pipes are not shown in the figure. The aforementioned fixing can be achieved by, for example, multiple screws, multiple bolts and nuts, or welding.

[0032] The working process of the deburring device for automobile cable joints of this preferred embodiment is roughly as follows:

[0033] The cable parallel conveying device of the cable processing equipment 3 mentioned above moves the cable joint 11 on the casting device 34 together with other parts of the cable horizontally to the top of the punching hole 211 of the lower fixed mold 21 of the deburring device 2. The controller 32 controls the pressing cylinder 24 at the top to move downward and pushes the punching cylinder 25 downward until the bottom end face of the upper punch 22 contacts the top surface of the cable joint 11. The electromagnetic induction switch 26 sends an electrical signal to the controller 32, and the controller 32 controls the punching cylinder 25 to punch downward. The punched cable joint 1 The cable 1 falls from the punching hole 211 of the lower fixed die 21 to the falling area 231 of the cable joint 11 below the lower fixed die 21. At this time, the cable parallel conveying device of the cable processing equipment 3 moves the cable joint 11 and the automobile cable 1 at the falling area 231 to the cable collection area. At the same time, the burrs remaining on the top surface 213 on one side of the boss 212 of the lower fixed die 21 are horizontally picked up by the cable joint shifting structure 31 of the cable parallel conveying device of the cable processing equipment 3 to the burr collection area.

[0034] Another embodiment of the pressing and punching cylinders can be employed: the pressing cylinder is a first lifting cylinder mounted on the frame, a second lifting cylinder being secured to the free end of the first piston rod of the first lifting cylinder, the free end of the piston rod of the second lifting cylinder being secured to the top of the upper punch, and the first and second lifting cylinders being electrically connected to a controller. A height position sensor can be employed, mounted at the free end of the piston rod or at the top of the upper punch (so as not to interfere with punching), and the height position sensor is also electrically connected to the controller.

If there is any inconsistency between the drawings and the text description or between the drawings, the text description shall prevail.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
