[0002] As for flattening the car wiper arm, the current common practice in the market is to use a press or special equipment to flatten it in one go. The flattening principle of this type of equipment is mostly to flatten the car wiper arm through a hydraulically driven mechanical mechanism.

[0003] As for controlling the two parameters of output pressure and displacement, most conventional products on the market use servo electric cylinders. The present invention combines two existing mature technologies to solve the problem of flattening the wiper arm of an automobile, while also achieving precise control of the forming dimensions during the flattening process.

[0004] Disadvantages of existing technology:

[0005] (1) Flattening is done by a large-tonnage hydraulic press in one step, and the forming size is uncontrollable and difficult to adjust.

[0006] (2) Hydraulic mechanism is bulky, slow to respond, and prone to oil leakage, causing environmental pollution.

[0007] (3) Equipment maintenance costs are high. Summary of the invention

[0008] In order to solve the technical problems existing in the background technology, the present invention provides a numerically controlled high-speed precision extrusion device, which has a small size, a fast response speed, and a controllable and adjustable molding size.

[0009] The technical solution adopted by the present invention to solve its technical problem is:

[0015] Furthermore, the flattening motion assembly includes:

[0016] A fixed block, fixedly arranged on the load-bearing frame assembly;

[0017] A moving block is slidably arranged on the load-bearing frame assembly;

[0018] A central pressure block is fixedly connected to the telescopic end of the servo electric cylinder assembly;

[0022] Furthermore, a lubrication system component is installed on the flattening and forming motion component.

[0023] Furthermore, an automatic reset component is installed on the flattening and forming motion component. The automatic reset component includes a plurality of springs arranged in parallel, and both ends of the springs are respectively connected and fixed to the fixed block and the movable block.

[0024] Furthermore, the flattening forming mold assembly includes a fixed mold and a sliding mold, the fixed mold is fixedly connected to the load-bearing frame assembly, and the sliding mold is fixedly connected to the moving block.

[0049] The present invention is further described in detail below with reference to the accompanying drawings.

[0050] For the flattening of automobile wiper arms, the equipment is required to be able to control the size of the flattened product, which is very important for the subsequent assembly of the product. At the same time, the equipment is required to be able to quickly adjust the molding size according to different products.

[0051] For equipment docking, you can choose manual docking or automated docking. For automated product docking, the equipment can provide the necessary interfaces.

[0052] The manual loading method is to manually take the car wiper arm and put it into the specified position of the device according to the process requirements. The device is equipped with a positioning mechanism and an in-place detection mechanism. After the device receives the in-place signal, it can start working. After the flattening and forming work is completed, it can automatically reset. The finished product is manually unloaded, and the cycle is repeated.

[0053] The automated docking loading method is: the robot (or other automated device) grabs the car wiper arm, and puts the car wiper arm into the specified position of the device according to the process requirements. The device is equipped with a positioning mechanism and an in-place detection mechanism. After the device receives the in-place signal, it can start working, and after the flattening and forming work is completed, it can automatically reset. The robot (or other automated device) unloads the finished product. During the process, the device's product in-place detection signal and product flattening completion signal can interact with the robot (or other automated device) to jointly complete the arm flattening and forming operation. This reciprocating cycle.

[0054] The present invention discloses a CNC high-speed precision extrusion device, which can flatten the wiper arm of an automobile. Its specific structure includes: a load-bearing frame assembly 1, which serves as the load-bearing basis of the device during the flattening process of the wiper arm of the automobile, and plays a role in supporting the normal operation of the entire mechanism. It is generally made by a welding frame method or a metal integral processing method.

[0055] The load-bearing frame assembly 1 is provided with an openable and closable flattening mold assembly 5. During the operation of the device, the automobile wiper arm is transported to the designated position of the flattening mold assembly 5 by the push of the flattening conveying assembly. The design fully considers the deformation of mechanical parts during the force-bearing process, and adopts an inclined structure to ensure that the automobile wiper arm is formed to a qualified size at the designated flattening position.

[0056] The flattening motion assembly 2 is mounted on the load-bearing frame assembly 1. The specific structure of the flattening motion assembly 2 includes: a fixed block 204 fixedly mounted on the load-bearing frame assembly 1, a moving block 205 slidably mounted on the load-bearing frame assembly 1, and a central pressure block 201 fixedly connected to the telescopic end of the servo electric cylinder assembly 7. The connecting block 203 is hinged between the central pressure block 201 and the fixed block 204 and between the central pressure block 201 and the moving block 205. The connecting block 203 is hinged to the central pressure block 201 through a load-bearing cylinder 202, the connecting block 203 is hinged to the fixed block 204 through a load-bearing cylinder 202, and the connecting block 203 is hinged to the moving block 205 through a load-bearing cylinder 202.

[0057] The load-bearing cylinder structure is adopted to convert the horizontal thrust of the electric cylinder along the axial direction into the thrust of the vertical electric cylinder axial direction, which mainly plays the role of transmitting pressure, converting the direction of pressure and promoting the movement of the flattening forming mold assembly. The specific connection structure of the load-bearing cylinder 202 is as follows: the connecting block 203 is provided with an arc groove matching the load-bearing cylinder 202, and the arc of the arc groove is less than 180°. The fixed block 204 and the moving block 205 are also provided with an arc groove matching the load-bearing cylinder 202, and the arc of the arc groove is less than 180°. The load-bearing cylinder 202 is clamped between the arc groove of the fixed block 204 and the arc groove of the connecting block 203, and between the arc groove of the moving block 205 and the arc groove of the connecting block 203. Through the above structure The structure can conveniently separate the connecting block 203 from the fixed block 204 and the movable block 205, and the above structure can also be used between the central pressing block 201 and the connecting block 203, so as to realize the convenient disassembly of the flattening molding motion assembly 2. By replacing different components in the flattening molding motion assembly 2, such as the central pressing block 201, the movable block 205, the fixed block 204 and the movable block 205, etc., different mold closing strokes and closing forces can be achieved, thereby adjusting parameters such as molding size, molding pressure and molding speed.

[0058] The flattening motion component 2 is composed of a purely mechanical structure, so the contact surfaces between the components require reliable lubrication to ensure the smooth operation and life of the mechanism. Therefore, a lubrication system component 3 is installed on the flattening motion component 2. The lubrication system adopts an oil cup to store oil to provide lubricating oil for the lubrication system.

[0059] The flattening motion assembly 2 is also equipped with an automatic reset assembly 8, which plays a role in automatically resetting the flattening motion assembly 2 during the operation of the device. In order to ensure that the device can operate cyclically, the automatic reset assembly 8 includes a plurality of springs arranged in parallel, and the two ends of the springs are respectively connected and fixed to the fixed block 204 and the moving block 205. The flattening motion assembly 2 is automatically reset by the mold spring inside the flattening motion assembly 2 and the tension spring outside.

[0060] The servo electric cylinder assembly 7 drives the flattening mold assembly 5 to open and close through the flattening motion assembly 2. As the driving mechanism of the flattening motion assembly, the servo electric cylinder assembly 7 can realize high-precision processing in a compact space while matching an extremely fast production rhythm. The extruded size can also be adjusted within a certain range by program control of the assembly. In addition, the servo electric cylinder assembly 7 is equipped with a flattening size detection assembly 4. During the operation of the device, the flattening size detection assembly 4 serves to detect the position of the flattening mold assembly 5. The position of the electric cylinder output shaft during the flattening process of the automobile wiper arm is detected by a detection sensor, thereby ensuring that the size of the device is controllable during the flattening operation.

[0061] The flattening mold assembly 5 includes a fixed mold 501 and a sliding mold 502. The fixed mold 501 is fixedly connected to the load-bearing frame assembly 1, and the sliding mold 502 is fixedly connected to the moving block 205. The rear end of the flattening mold assembly 5 is equipped with a positioning mechanism assembly 6. The positioning mechanism assembly plays a role in positioning the automobile wiper arm product during the operation of the device. The specific structure of the positioning mechanism assembly 6 includes: a scale 604 fixedly set at the rear end of the flattening mold assembly 5 and a slider 602 slidably set at the rear end of the flattening mold assembly 5. The slider 602 is fixedly provided with a contact 601 and a pointer 603, and the pointer 603 indicates the scale on the scale 604. The contact 601 adopts an elastic reset mechanism, which plays a role in buffering and precise positioning during the positioning process of the automobile wiper arm product. At the same time, the assembly is equipped with a scale 604 to meet the visual operation of adjusting the position of the assembly during the changeover between different products.

[0062] An extrusion method comprises the following steps:

[0063] a. The automobile wiper arm is fed into the flattening molding die assembly 5 from the front end of the flattening molding die assembly 5;

[0064] b. The wiper arm of the car slides the slider 602 through the top of the contact 601, and the scale 604 indicated by the pointer 603 can show the position of the wiper arm of the car;

[0065] c. The servo electric cylinder assembly 7 drives the center pressing block 201 to move forward, and the center pressing block 201 drives the moving block 205 to slide through the connecting block 203, and the flattening molding mold assembly 5 is closed;

[0066] d. The fixed mold 501 and the sliding mold 502 squeeze and flatten the automobile wiper arm.

[0067] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
