Description

Technical Field

[0001] The present invention relates to the technical field of automotive part processing, and more specifically, to a precision and high-efficiency hybrid die and processing method for automotive parts. Background Art

[0002] When precisely processing some automotive parts, a common situation is that in the processing technological process of the parts, the latter part of the process requires ensuring processing precision, while the former part of the process has no great precision requirements. For this kind of processing situation with precision requirements, currently, a set of transfer dies are mostly directly used for fine processing. This results in waste of resources and low efficiency during the processing of the former part of the process. To solve this problem, a precision processing progressive die and transfer die hybrid die and method for automotive parts are needed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a precision and high-efficiency hybrid die and processing method for automotive parts in view of the above-mentioned defects of the prior art.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0005] Construct a precision and high-efficiency hybrid die for automotive parts, which includes a continuous processing die, a transition mechanism, a transfer processing die, and a control host; the transition mechanism includes a material sensor for sensing the workpiece after continuous processing by the continuous processing die, a cutting die for cutting and separating the workpiece after processing, and a manipulator for feeding the cut and separated workpiece into the transfer processing die; both the continuous processing die and the transfer processing die are controlled by the control host, and the control host is further used to control the cutting die to perform cutting and separating operations on the workpiece according to the die closing rhythm of the continuous processing die, and control the manipulator to feed the cut and separated workpiece into the transfer processing die according to the transfer rhythm of the transfer processing die.

[0006] In the precision and high-efficiency hybrid die for automotive parts of the present invention, the transition mechanism further includes a temporary storage station; a workpiece sensor is provided at the frontmost processing position of the transfer processing die. When the workpiece sensor senses the presence of material during the control of the manipulator to feed the frontmost processing position of the transfer processing die, the control host controls the manipulator to store the workpiece in the temporary storage station. Of course, when the workpiece sensor senses the absence of material, the control host controls the manipulator to feed the workpiece into the frontmost processing position of the transfer processing die.

[0007] The hybrid mold for precise and efficient processing of automobile parts described in the present invention is characterized in that a workpiece counter and a material transfer carrier are provided on the temporary material storage station; the workpiece counter counts the stored workpieces, and when the number reaches a set value, the material transfer carrier transfers the workpiece to a spare transfer processing mold for processing.

[0008] The hybrid mold for precise and efficient processing of automobile parts described in the present invention comprises an upper mold and a lower mold; the lower mold is provided with a positioning fixture for positioning the workpiece and a concave mold for cutting the workpiece; the upper mold is provided with a floating pressure block facing the positioning fixture and a cutter cooperating with the concave mold; the opening and closing movement of the upper mold is controlled by the control host.

[0009] The hybrid mold for precise and efficient processing of automobile parts of the present invention comprises: the workpiece partially protrudes from the lower mold when located on the positioning fixture; the material sensor comprises a sensing bracket, on which a longitudinally distributed infrared transmitter and infrared receiver are arranged.

[0010] A method for processing a hybrid mold for precise and efficient processing of automobile parts is applied to the hybrid mold for precise and efficient processing of automobile parts as described above, and the implementation method is as follows:

[0011] The continuous processing mold processes the entire hardware plate, and the finished workpiece is sent into the cutting mold to trigger the material sensor;

[0012] After receiving the signal from the material sensor, the control host obtains the latest mold closing state time of the continuous processing mold, controls the cutting mold to run when the continuous processing mold is in the latest mold closing state, and cuts and separates the workpiece processed by the continuous processing mold from the whole hardware plate;

[0013] The control host obtains the most recent mold opening state time at the frontmost station of the transfer processing mold, and controls the manipulator to operate when the transfer processing mold is in the most recent mold opening state to feed the cut and separated workpiece into the transfer processing mold;

[0014] The transfer processing mold continues to transfer the fed workpiece and unload the finished product.

[0015] The hybrid mold processing method for precise and efficient processing of automobile parts of the present invention further includes the following method:

[0016] When the control host controls the manipulator to operate and feed at the machining position at the forefront of the transfer machining die, if the workpiece sensor senses the presence of a workpiece, the control host controls the manipulator to store the workpiece in the temporary storage station. Of course, when the workpiece sensor senses the absence of a workpiece, the control host controls the manipulator to send the workpiece to the machining position at the forefront of the transfer machining die; when the number of workpieces stored in the temporary storage station reaches the set value, the material transfer carrier transfers the workpieces to the spare transfer machining die for machining.

[0017] The beneficial effects of the present invention are as follows: The continuous machining die processes the whole metal plate, and the machined workpiece triggers the material sensor after being sent into the cutting die; after the control host receives the signal from the material sensor, it obtains the time of the last mold closing state of the continuous machining die, and controls the cutting die to operate when the continuous machining die is in the last mold closing state to cut and separate the workpiece machined by the continuous machining die from the whole metal plate; the control host obtains the time of the last mold opening state at the forefront station of the transfer machining die, and controls the manipulator to operate when the transfer machining die is in the last mold opening state to send the cut and separated workpiece into the transfer machining die; the transfer machining die continues to transfer and machine the fed workpiece and discharges the finished product; by applying the method of the present application, the forming part with relatively low precision requirements in the conventional process can be quickly machined by the continuous machining die, and the subsequent processes requiring precision machining are realized by the transfer machining die, and the transition mechanism plays a connecting role in the middle. Moreover, by using the special transition mechanism of the present application, it is not necessary for the continuous machining die and the transfer machining die to operate synchronously, and they can be processed separately and asynchronously. In this way, the restrictions on the continuous machining die and the transfer machining die that can be spliced together are greatly reduced, making the combined machining extremely flexible.
