Description

Technical Field

[0001] This invention relates to cable end production equipment, and more particularly to a multi-station cable end production equipment. Background Technology

[0002] Cables are widely used in control cable systems in industries such as automobiles, motorcycles, electric bicycles, and bicycles. The application of cable products in home decoration industries such as lighting fixtures, electric curtains, and fitness equipment is also developing rapidly. The ends of cables are generally made by die casting of zinc alloy.

[0003] Currently, most production methods involve manually or with robotic assistance placing single or multiple cables into a die-casting mold for die casting. The cables are then manually removed and placed onto a suitable press for deburring and trimming. This production method is inefficient and unsafe. While automatic deburring machines have emerged, their poor stability, low efficiency, and high cost have hindered widespread adoption. To meet market demands, a new integrated die-casting and deburring machine is becoming increasingly necessary. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-station cable end production equipment. This invention automatically grips the cable for die casting, and simultaneously automatically grips the cable end for deburring and removing burrs, thus balancing production efficiency and product quality while improving production safety.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-station cable end production equipment includes:

[0007] The machine base and mold base are provided. The mold base is fixedly mounted on the machine base. A mold locking and force amplification mechanism is installed on the upper part of the mold base. The bottom of the telescopic rod of the mold locking and force amplification mechanism is connected to an upper mold mounting slider assembly. The slide rail of the upper mold mounting slider assembly is fixedly mounted on the mold base. A die-casting upper mold is mounted at the bottom of the upper mold mounting slider assembly. A die-casting lower mold is fixedly mounted on the mold base directly below the die-casting upper mold. An end ejection cylinder is mounted on the mold base below the die-casting lower mold. A left support and a right support are respectively mounted on the left and right ends of the front of the mold base. A hinged rotating shaft is mounted on the right support. The cable end processing mechanism allows the cable end processing mechanism to rotate around the hinge shaft. Opening the cable end processing mechanism facilitates the loading and unloading of the die-casting mold and the maintenance and repair of related internal parts. The left support is equipped with positioning screw holes and a fixed adjusting screw assembly. A cable guide plate is fixedly mounted on the mold base on the top right side of the die-casting lower mold. A punching device is mounted on the right side of the cable guide plate on the mold base. The upper mold and lower mold are also equipped with upper mold adhesion alarm devices and lower mold adhesion alarm devices respectively on the mold base and the lower top plate.

[0008] Preferably, the cable end processing mechanism is equipped with a guide rail mounting plate, which is connected to the right support via a hinged pivot. Adjusting the screw of the fixing screw assembly ensures that when the guide rail mounting plate is closed, the top of the screw fits against the plate, guaranteeing precise vertical positioning. The guide rail mounting plate also has positioning holes corresponding to the positioning screw holes, allowing the cable end processing mechanism to be fixed to the left support using the screws. A linear guide rail is mounted on the outer side of the guide rail mounting plate, and a cylinder mounting plate is mounted on the top of the guide rail mounting plate. The cylinder mounting plate is equipped with left and right movement mechanisms via a cylinder bracket. The cylinder rod of the left and right moving cylinder is equipped with an L-shaped cylinder connecting rod at its front end. The other end of the L-shaped cylinder connecting rod is fixed to the connecting plate. A linear guide slider is installed on the inner side of the connecting plate. The linear guide slider is installed in conjunction with the linear guide. A casting clamping device and a punching clamping device are installed on the lower part of the connecting plate. A left limit device is installed on the outer side of the cylinder mounting plate, and a right limit device is installed on the right side of the guide rail mounting plate. A stroke block is installed on the connecting plate between the left limit device and the right limit device to limit the stroke range of the connecting plate, the casting clamping device, and the punching clamping device.

[0009] Preferably, the casting clamping device is equipped with upper and lower casting clamp cylinders fixedly mounted on a connecting plate. The cylinder rods of the upper and lower casting clamp cylinders are connected to the upper and lower casting clamp cylinder mounting plates. The bottom of the upper and lower casting clamp cylinder mounting plates is equipped with a casting clamp cylinder mounting plate. The casting clamp cylinder is connected to a casting clamp front body and a casting clamp rear body. Casting clamp positioning plates are installed on the outer sides of both the casting clamp front body and the casting clamp rear body. The bottom of the casting clamp front body and the casting clamp rear body are provided with casting clamping parts. The corresponding casting clamping parts in the casting clamp rear body are provided with dovetail grooves. Rubber blocks are embedded in the dovetail grooves. The casting clamping cylinders control the left and right movement of the casting clamp front body and the casting clamp rear body to open and close the casting clamping parts at the bottom of the casting clamp front body and the casting clamp rear body, thereby achieving the gripping of the cable. The rubber blocks are elastic to ensure that the corresponding cables have clamping force.

[0010] Preferably, the punch clamping device includes upper and lower punch clamp cylinders fixedly mounted on a connecting plate. The cylinder rods of the upper and lower punch clamp cylinders are connected to a punch clamp cylinder mounting plate. A punch clamp moving cylinder and a punch clamp slider are mounted at the bottom of the mounting plate. A matching punch clamp guide rail is mounted on the punch clamp slider. A guide rail mounting plate is mounted at the bottom of the guide rail. One side of the guide rail mounting plate is connected to the telescopic rod of the punch clamp moving cylinder. A punch clamp cylinder mounting plate is mounted at the bottom of the guide rail mounting plate. A punch clamp cylinder is mounted on the mounting plate. The punch clamp cylinder is connected to a punch clamp front body and a punch clamp rear body. Punch clamp positioning plates are mounted on the outer sides of both the front and rear punch clamp bodies. A brush connecting rod is also mounted on the right side of the punch clamp cylinder mounting plate, with a brush mounted at the other end. Punch clamping portions are located at the bottom of both the front and rear punch clamp bodies. A dovetail groove is provided in the corresponding punch clamping portion of the rear punch clamp body. The dovetail groove is embedded within... Equipped with rubber blocks, the front and rear bodies of the punch clamp are moved left and right by the punch clamp cylinder, realizing the opening and closing of the punch clamping parts at the bottom of the front and rear bodies, thereby gripping the cable and performing synchronously with the casting clamping device. The brush can clean the waste generated by the punching and repair device and apply lubricating oil to the die. The rubber blocks can clamp the corresponding cables tightly, and when the punch clamp moving cylinder works to drive the punch clamping part to pull the cable against the positioning surface, it will apply tension to the cable. It can also make the punch clamping part slide with the cable to avoid scratching the cable surface.

[0011] In this invention, the pre-casting clamp body and the pre-punching clamp body have the same structure, and the post-casting clamp body and the post-punching clamp body have the same structure.

[0012] Preferably, the punching device includes a left punching plate and a right punching plate mounted on the die holder. The left and right punching plates are connected and fixed by a top punching plate and an inner punching back plate. A punching guide rail is fixedly mounted on the back plate. A die mounting plate is mounted in the middle of the left and right punching plates, and a die is mounted on the top of the die mounting plate. The die has a die platform, and a die baffle is provided at the front end of the die platform. A die hole is formed at the intersection of the die platform and the inner side of the die baffle. The die hole has an angled end guide surface at the die platform. The die hole and the end guide surface are adjusted according to the shape and size of the end. The die hole extends upwards onto the die baffle to form a positioning surface. A cable groove connecting to the die hole is centrally formed on the positioning surface. Cable guide surfaces are formed on both sides of the cable groove at the top of the die baffle. The cable guide surfaces are inverted triangles or arcs to facilitate the smooth entry of the cable. The die has a groove and a pusher handle through hole on the side. A die hydraulic cylinder is mounted on the die repair top plate. The cylinder rod of the die hydraulic cylinder passes through the die repair top plate. A die cylinder mounting plate is mounted on one side of the die repair right side plate. A die cylinder is mounted on the die cylinder mounting plate. A die cylinder connecting block is connected to the cylinder rod of the die cylinder. The other end of the die cylinder connecting block is fixedly connected to the die movable block. A die repair slider matching the die repair guide rail is fixedly mounted on the back of the die movable block. The top of the die movable block is adjacent to the cylinder rod of the die hydraulic cylinder. A punch rod mounting block is fixedly mounted on the bottom. A punch rod matching the die hole groove is mounted on the bottom of the punch rod mounting block. A pusher cylinder mounting plate is also mounted on one side of the die repair right side plate. A pusher cylinder is mounted on the pusher cylinder mounting plate. A pusher push rod is connected to the top of the pusher cylinder. The pusher push rod extends from the pusher handle through hole to the other end. A die limit sensor switch is mounted on the die cylinder housing.

[0013] Preferably, the upper mold adhesion alarm device is located on both sides of the die-casting upper mold, with an upper insulating block fixedly mounted on the mold base. The two upper insulating blocks are connected by an upper conductive block, one end of which is connected to an upper wire. When the end of the upper insulating block adheres to the die-casting upper mold, the die-casting upper mold will rise with the end when it returns to its original position, causing the cable to obliquely touch the upper conductive block. At this time, the machine will sound an alarm and stop working. If the cable is covered with an insulating layer, the upper conductive block can be replaced with a micro switch with a long contact rod.

[0014] Another design uses an insulating plate as the mounting plate for the upper and lower cylinders of the casting clamp, with the upper wire connected to the mounting plate. This insulates the upper and lower cylinders of the casting clamp from the front and rear bodies of the casting clamp. When the end sticks to the die-casting mold, the die-casting mold will lift the end when it returns to its original position. The cable will then obliquely touch the front or rear body of the casting clamp, at which point the machine will sound an alarm and stop working.

[0015] Preferably, the lower mold adhesion alarm device has a lower top plate slidingly fitted onto four top plate guide pillars. The top plate guide pillars are fixedly installed under the die-casting lower mold. Several end ejection rods are installed on the lower top plate above the cylinder rod of the end ejection cylinder. The upper ends of the end ejection rods are located inside the die-casting lower mold. The lower top plate is located outside the die-casting lower mold and is sequentially equipped with a lower connecting block and a lower auxiliary guide plate. A lower insulating block is installed on the lower connecting block, and a lower conductive block is installed on the lower insulating block. The top of the lower auxiliary guide plate is higher than the top of the lower conductive block. When the end ejection rod ejects the end, if any ejection rod is bent, broken, or if the end shape is special and ejection rods cannot be installed, the end will adhere to the die-casting lower mold. When the cylinder rod of the ejection cylinder pushes the lower top plate upward, the lower auxiliary guide plate and the lower conductive block will rise synchronously, causing the cable to touch the lower conductive block. At this time, the machine will sound an alarm and stop working.

[0016] If the cable has an insulating layer, replace the lower conductive block 99 with a micro switch with a long contact rod.

[0017] The present invention has the following beneficial effects:

[0018] 1. Compared with the prior art, the present invention improves production efficiency and quality by automatically performing punching repair on the cable ends, and effectively reduces labor costs and improves production safety.

[0019] 2. Compared with the prior art, the casting clamping device and punching clamping device of the cable end of the present invention can swing open and close, which facilitates the loading and unloading of die-casting molds and the maintenance and repair of related components. In addition, the casting clamping device and the punching clamping device are linked, which shortens the cycle time, improves production efficiency, simplifies the movement path, reduces related components, and reduces the overall size of the machine; a lower mold adhesion alarm device and an upper mold adhesion alarm device are provided to ensure that related parts are not damaged during cyclic operation, thereby improving the reliability of the machine.

[0020] 3. Compared with the prior art, the present invention can facilitate the manufacture and installation of the punching die, while ensuring the precise positioning of the cable end and the punching hole, and has an alarm function for the punching product not in place, so as to avoid damage to the punching die and punch rod during the punching of the cable end to the deburring shank and burrs.

[0041] The casting clamping device 4 is equipped with a casting clamping upper and lower cylinder 41 fixedly mounted on a connecting plate 38.

[0042] The punch clamping device 5 includes a punch clamping upper and lower cylinder 51 fixedly mounted on a connecting plate 38. The cylinder rod of the punch clamping upper and lower cylinder 51 is connected to a punch clamping upper and lower cylinder mounting plate 52.

The device is equipped with a dovetail groove 49, in which a rubber block is embedded. The left and right movement of the front body 59 and the rear body 60 of the punch clamp is controlled by the punch clamp cylinder 58, so as to realize the opening and closing of the punch clamp part 67 at the bottom of the front body 59 and the rear body 60, thereby realizing the gripping of the cable. This is synchronized with the casting clamp device 4. The brush 63 can clean the waste generated by the punching and repair device 7 and apply lubricating oil to the die. The rubber block can clamp the corresponding cables. When the punch clamp moving cylinder 53 works and drives the punch clamp part to pull the cable against the positioning surface 87, it will apply tension to the cable and also make the punch clamp part slide with the cable to avoid scratching the cable surface.

[0043] In this invention, the casting clamp front body 45 and the punching clamp front body 59 have the same structure, and the casting clamp rear body 46 and the punching clamp rear body 60 have the same structure.

[0044] The punching and repair device 7 includes a left punching and repair plate 71 and a right punching and repair plate 74 mounted on the mold base 2. The left punching and repair plate 71 and the right punching and repair plate 74 are connected and fixed via a top punching and repair top plate 75 and an inner punching and repair back plate 64. A punching and repair guide rail 66 is fixedly mounted on the back plate 64. A die mounting plate 72 is mounted in the middle of the left punching and repair plate 71 and the right punching and repair plate 74. A die 73 is mounted on the top of the die mounting plate 72. The die 73 has a die platform 68, and a die baffle 69 is located at the front end of the die platform 68. The die platform 68 and... A die hole 88 is formed at the intersection of the inner sides of the die baffle 69. The die hole 88 is located on the die platform 68 and has an angled end guide surface 100. The die hole 88 and the end guide surface 100 are adjusted according to the shape and size of the end. The die hole 88 extends upwards onto the die baffle 69 to form a positioning surface 87. A cable groove 89 connecting to the die hole 88 is formed in the center of the positioning surface 87. Cable guide surfaces 90 are formed on both sides of the cable groove 89 at the top of the die baffle 69. The cable guide surfaces 90 are inverted triangles or arcs to facilitate cable pulling. Successfully entering the cable groove 89, the die 73 also has a pusher handle through hole on its side.

The cylinder rod of the die cylinder 78 is connected to a die cylinder connecting block 79, and the other end of the die cylinder connecting block 79 is fixedly connected to a die movable block 80. The back of the die movable block 80 is fixedly equipped with a part that matches the die repair guide rail 66.

[0045] The upper mold adhesion alarm device 9 is located on both sides of the die-casting upper mold 23, with an upper insulating block 91 fixedly installed on the mold base 2. The two upper insulating blocks 91 are connected by an upper conductive block 92. One end of the upper conductive block 92 is connected to an upper wire 93. When the end of the upper insulating block 91 adheres to the die-casting upper mold 23, the die-casting upper mold 23 will rise with the end when it returns to its original position. The cable will then obliquely touch the upper conductive block 92, at which point the machine will sound an alarm and stop working. If the cable is covered with an insulating layer, the upper conductive block 92 can be replaced with a micro switch with a long contact rod.

[0046] Another design is that the upper and lower cylinder mounting plates 42 of the casting clamp are insulated plates, and the upper wire 93 is connected to the cylinder mounting plate 43 of the casting clamp, so that the upper and lower cylinders 41 of the casting clamp are insulated from the front body 45 and the rear body 46 of the casting clamp. When the end sticks to the die-casting upper mold 23, the die-casting upper mold 23 will rise with the end when it returns to its original position. The cable will then obliquely touch the front body 45 or the rear body 46 of the casting clamp. At this time, the machine will sound an alarm and stop working.

[0047] The lower mold adhesion alarm device 10 includes a lower top plate 94 that is slidably fitted onto four top plate guide pillars 120. The top plate guide pillars 120 are fixedly installed below the die-casting lower mold 24. Several end ejection rods 95 are mounted on the lower top plate 94 above the cylinder rod of the end ejection cylinder 11. The upper ends of the end ejection rods 95 are located inside the die-casting lower mold 24. A lower connecting block 96 and a lower auxiliary guide plate 97 are sequentially mounted on the lower top plate 94 outside the die-casting lower mold 24. A lower insulating block 98 is mounted on the lower connecting block 96. The lower conductive block 99 is mounted on block 98. The top of the lower auxiliary guide plate 97 is higher than the top of the lower conductive block 99. When the end ejector rod 95 ejects the end, if the ejector rod is bent or broken, or if the end cannot be set due to its special shape, the end will stick to the die-casting lower mold 24. When the cylinder rod of the ejector cylinder 11 pushes the lower top plate 94 to rise, the lower auxiliary guide plate 97 and the lower conductive block 99 will rise synchronously, causing the cable to touch the lower conductive block 99. At this time, the machine will sound an alarm and stop working.

[0048] If the cable has an insulating layer, replace the lower conductive block 99 with a micro switch with a long contact rod.

[0049] The functional principle of this invention can be explained through the following operation: First, a cable placement detection device is installed on the left side of the mold base 2. The machine is started and the automatic working state is selected. On the placement plate, cables of the corresponding specifications and quantities are manually placed. The cable detection button is pressed, and the corresponding cables automatically enter the cable end pattern position detection and cable end pattern detection. If there is an abnormality, the machine alarms. If the detection is passed, the left and right moving cylinder 34 controls the connecting plate 38 to move to the left, driving the casting clamp front body 45 and casting clamp rear body 46 of the casting clamp device 4 to come above the cable placement detection device. At the same time, the brush 63 on the brush connecting rod 62 in the punch clamp device 5 is driven to clean and lubricate the punch hole 88 and positioning surface 87 in the punch die 73. Then the punch clamp front body 59 and punch clamp rear body 60 come above the die casting lower mold. At this time, the casting clamping part 48 under the casting clamping front body 45 and casting clamping rear body 46 is in the open state. Then, the casting clamping upper and lower cylinders 41 control the downward movement, and the casting clamping cylinder 44 controls the closing. The casting clamping part 48 clamps the corresponding cable. Then, the casting clamping upper and lower cylinders 41 control the upward movement of the cable. At the same time, the punching device 5 on the die-casting lower mold also completes the corresponding action. However, when the punching upper and lower cylinders 51 control the upward movement of the cable with the stalk end (the first mold does not have a cable with the stalk end), the oil is ejected. Simultaneously, the telescopic rod of cylinder 11 pushes the ejector rod 95 at the middle end of the lower top plate 94 upward. Then, the left-right moving cylinder 34 controls the connecting plate 38 to move to the right, bringing the cable in the casting clamping device 4 above the die-casting lower mold 24. Then, the casting clamping upper and lower cylinder 41 controls the downward movement, placing the cable in the casting clamping device 4 into the corresponding position in the cavity of the die-casting lower mold 24. Then, the die-casting upper mold 23 moves downward and merges with the die-casting lower mold 24 to perform injection die-casting. After a delay, the die-casting upper mold 23 moves upward. After mold opening is completed, the clamping device 5, holding the cable with the stalk end (the first mold does not have a cable with the stalk end), is brought along the cable guide plate 29 to the top of the die 73. Then, the clamping cylinder 51 moves downward, pulling the cable with the stalk end held in the clamping device 5 through the cable guide surface 90 in the die 73 into the cable groove 89, so that the cable with the stalk end is placed near the positioning surface 87. At this time, the clamping moving cylinder 53 drives the clamping cylinder 58 to move outward, so that the cable with the stalk end... Under the clamping force of the punch clamp, the cable pulls the side of the material handle end of the cable against the positioning surface 87 in the punch die 73. At this time, the telescopic rod of the punch die cylinder 78 in the punch repair device 7 moves downward. The magnitude of the downward movement force is adjusted by the working air pressure of the punch die cylinder 78, and the downward position is adjusted by the position of the punch die limit sensor switch 86 on the outer shell of the punch die cylinder 78, ensuring that the material handle end of the cable enters the end guide surface 100 above the punch repair hole 88 along the positioning surface 87 in the punch die 73. The punch die cylinder 78 only participates in positioning and does not participate in punch repair, so the downward force and position adjustment must be appropriate. If an abnormality occurs and the sensor switch does not reach the set position, a delayed alarm will be triggered to protect the punch die 73 and the punch rod 82 from damage.

[0050] When the die limit sensor switch 86 on the outer shell of the die cylinder 78 sends a signal, the die clamping cylinder 58 in the die clamping device 5 controls the die clamping part 67 to release, and the die clamping up and down cylinder 55 moves upward. At the same time, the die clamping cylinder 44 in the die clamping device 4 controls the die clamping part 48 to release, and the die clamping up and down cylinder 41 moves upward. At this time, if the cable detection button is pressed, as long as the conditions for entering the next cycle are met, the left and right moving cylinder 34 in the cable end processing mechanism 31 controls the connecting plate 38 to move from right to left, and the machine enters the next cycle.

[0051] Simultaneously, when the clamping cylinder 58 in the clamping device 5 controls the clamping part 67 to release, the telescopic rod of the hydraulic cylinder 76 in the repair device 7 moves downward. At this time, the telescopic rod of the die cylinder 78 continues to move downward. When the cable end passes through the die hole 88 of the die 73 that matches the cable end through the punch rod 82, the telescopic rods of the die hydraulic cylinder 76 and the die cylinder 78 in the repair device 7 return simultaneously, and the cable end and the material handle enter the corresponding collection devices respectively.

[0052] The machine's operating instructions are implemented by a programmable logic controller (PLC) for program control.

[0053] This equipment can process eight cable end products at a time. The specific number depends on the shape and size of the end products. The corresponding molds are processed, and production only requires changing the molds and corresponding accessories.

[0054] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
