Description

Technical Field

[0001] The invention belongs to the field of rapid adjustment of a centering punch, and in particular relates to a process method, electronic equipment, a server and a storage medium for rapid adjustment of a centering punch. Background Art

[0002] In order to improve production efficiency, the automotive panel mold industry is increasingly using high-precision equipment to ensure processing accuracy, and accordingly, the number of manual factors is decreasing. For example, in the past, the assembly and blanking clearance of the punching punch were mostly manually adjusted by fitters, which was inefficient. Now most mold factories use centering punches and process centering holes through CNC equipment, which greatly improves the production efficiency of punching punch assembly. After continuously optimizing the work process and processing and assembly operation specifications, our company currently has a first adjustment pass rate of more than 93% using centering punches. However, even so, due to various factors, position accuracy still exceeds tolerance from time to time. How to quickly adjust the remaining 7% to meet the requirements is a problem that needs to be solved.

[0003] like Figure 1 For the existing centering punch, the current centering punch processing and assembly process is roughly as follows:

[0004] 1. CNC machine the centering pin hole of the upper die seat and the bottom hole for screw fixing. At this time, the positioning pin hole of the fixed seat is not machined.

[0005] 2. The fitter taps the screw fixing hole, obtains the centering punch and fixing seat assembly, and assembles them by positioning the locating pin.

[0006] 3. After assembly is completed, close the mold and test punch on the press. First, test the press without the parts, check the cutting edge of the punch one by one, and see if there is any biting or blackening. Then test punch with the parts, check the cutting edge of each hole, and judge whether the cutting edge of the male and female dies is uniform.

[0007] 4. If the punch is blackened during the idle stroke or the burr on one side of the workpiece hole is large, it means that the gap between the male and female dies is abnormal and the punch position needs to be adjusted.

[0008] 5. At this time, the positioning pin needs to be removed, but once the pin is removed and reassembled, the reference is lost due to the large through hole of the fixing seat screw. In this case, most mold factories still use the most primitive notch method to solve it.

[0009] Disadvantages of the current original adjustment method:

[0010] After the punching gap is found to be uneven, the punch position needs to be fine-tuned. At this time, the positioning pin must be removed. The detachable pin must first remove the punch fixing block, pull out the pin and then re-fix it, but this will lose the assembly reference. To fine-tune the gap, the most primitive notching method must be used, which is troublesome, time-consuming, labor-intensive and inefficient. Summary of the invention

[0011] In view of this, the present invention aims to provide a process method, electronic equipment, server and storage medium for rapid adjustment of a centering punch, so as to solve at least one problem existing in the above-mentioned prior art.

[0012] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0013] A process method for rapid adjustment of a centering punch is implemented by an automobile panel mold, wherein the automobile panel mold comprises an upper mold, a punch fixing seat, a locating pin, a hexagon socket screw, an internally threaded locating pin, a ball locking punch, a lower mold, a die fixing seat and a ball locking die, wherein the upper mold is located above the lower mold, the punch fixing seat is connected to the bottom of the upper mold by means of a hexagon socket screw and an internally threaded locating pin, a ball locking punch is arranged inside the punch fixing seat, the ball locking punch is connected to the bottom of the upper mold by means of a locating pin, the top of the lower mold is connected to the die fixing seat by means of a die pad, and a ball locking die is arranged on the die fixing seat;

[0014] The process comprises the following steps:

[0015] S1, CNC machining seat positioning pin hole and hexagon socket screw fixing bottom hole, at this time the internal thread positioning pin hole is not processed;

[0016] S2. The fitter taps the screw fixing hole, takes out the ball locking punch and the fixing seat assembly, and assembles them by positioning the positioning pin;

[0017] S3. After the assembly is completed, close the mold and test punch on the press; first test the press without the parts, check the cutting edge of the ball locking punch one by one, and see if there is any biting or blackening. Then test punch with the parts, check the cutting edge of each hole, and judge whether the cutting edge of the punch and the concave die is uniform;

[0018] S4. If the punch is scratched or the burr on one side of the workpiece hole is large during the idle stroke, it means that the gap between the male and female dies is abnormal and the punch position needs to be adjusted.

[0019] S5. At this time, the positioning pin needs to be removed and the clearance needs to be fine-tuned using the optimal solution to complete the assembly.

[0020] Further, in step S5, the preferred scheme is method A, which comprises:

[0021] Remove the locating pin and use a reamer to expand the centering pin hole on the punch fixing seat. The original locating pin is φ6H7 / m6, and the single-sided blanking clearance of thin plate punching is 0.03-0.05mm, so the amount of hole expansion should not exceed 0.04 in diameter. After expansion, use the locating pin again for assembly and test punching. If deviation is found, there is no need to disassemble. Since there is a certain gap between the pin and the hole at this time, fine-tuning can be carried out. After qualified adjustment, the pin hole of the fixing seat is matched to complete the assembly.

[0022] Further, in step S5, the preferred solution is method B, which includes:

[0023] A1. Make your own aluminum pins with the same size and specifications as the positioning pins used, and store them in the warehouse for use. The positioning pins originally purchased with the punches are made of steel and have been quenched to have a certain hardness. They cannot be adjusted after assembly.

[0024] A2. After the original positioning pin is used for assembly and test punching, if the ball locking punch is found to have an abnormal clearance, remove the positioning pin and replace it with an aluminum pin for reassembly. First, loosen the fixing screw and tap and adjust the fixing seat according to the clearance deviation. Since there is a pin as a reference and the pin is aluminum and relatively soft, the aluminum pin will produce plastic deformation during fine-tuning of the clearance, which can ensure the adjustability of the clearance. After fine-tuning and test punching, when the clearance is qualified, the fitter tightens the fixing screw and makes the pin hole of the fixing seat, and the assembly is completed.

[0025] Furthermore, the automobile covering part mold also includes a punch pad and a die pad, and the bottom of the upper mold is mounted with a punch fixing seat through the punch pad.

[0026] Furthermore, the automobile cover mold also includes a steel ball, and a steel ball is provided on one side of the ball locking die.

[0027] Furthermore, the automobile cover mold also includes a thread blocking block, and the punch fixing seat is also provided with a thread blocking block, and the thread blocking block cooperates with the internal thread positioning pin.

[0028] An electronic device comprises a processor and a memory which is in communication with the processor and is used to store instructions executable by the processor, wherein the processor is used to execute the process method for rapid adjustment of the centering punch.

[0029] A server includes at least one processor and a memory connected to the processor in communication, wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the processor so that the at least one processor executes the process method for rapid adjustment of the centering punch.

[0030] A computer-readable storage medium stores a computer program, wherein the computer program is executed by a processor to implement the process method for rapid adjustment of a centering punch.

[0031] Compared with the prior art, the process method, electronic equipment, server and storage medium for rapid adjustment of a centering punch described in the present invention have the following advantages:

[0032] The process method, electronic equipment, server and storage medium for rapid adjustment of a centering punch described in the present invention change the material of the locating pin to aluminum, effectively transmit the reference, and improve adjustability. The operation is simple, which facilitates operators to complete the debugging work faster and more effectively. In addition, the process method is not only applicable to punching punches, but also to other components with centering functions, such as flanging punches, assembly-type workpiece locating pins, guide pins, etc. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0041] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0042] like Figure 2 As shown, a process method for rapid adjustment of a centering punch is implemented by an automobile cover mold, and the automobile cover mold includes an upper mold, a punch fixing seat, a punch pad, a locating pin, an inner hexagon screw, an internal thread locating pin, a threaded plugging block, a ball locking punch, a lower mold, a die fixing seat, a ball locking die, a steel ball and a die pad. The upper mold is located above the lower mold, and the bottom of the upper mold is equipped with a punch fixing seat through a punch pad. The punch fixing seat and the bottom of the upper mold are also connected by inner hexagon screws and internal thread locating pins. A threaded plugging block is also provided in the punch fixing seat, and the threaded plugging block cooperates with the internal thread locating pin. A ball locking punch is provided inside the punch fixing seat, and the ball locking punch is connected to the bottom of the upper mold through the locating pin through the punch pad. The top of the lower mold is connected to the die fixing seat through the die pad. A ball locking die is provided on the die fixing seat, and a steel ball is provided on one side of the ball locking die.

[0043] The process comprises the following steps:

[0044] S1, CNC machining seat positioning pin hole and hexagon socket screw fixing bottom hole, at this time the internal thread positioning pin hole is not processed;

[0045] S2. The fitter taps the screw fixing hole, takes the centering punch (ball locking punch) and the fixing seat assembly, and assembles them by positioning the positioning pin;

[0046] S3. After the assembly is completed, the mold is closed and the press is tested. First, test the press without the parts, check the cutting edge of the punch one by one, and see if there is any biting or blackening. Then test the punch with the parts, check the cutting edge of each hole, and judge whether the cutting edge of the male and female dies is uniform.

[0047] S4. If the punch is scratched or the burr on one side of the workpiece hole is large during the idle stroke, it means that the gap between the male and female dies is abnormal and the punch position needs to be adjusted.

[0048] S5. At this time, the positioning pin needs to be removed and the clearance needs to be fine-tuned using the optimal solution to complete the assembly.

[0049] As mentioned above, to fine-tune the gap, the positioning pin on the original punch must be removed, but the assembly reference is lost when the punch is reassembled after removal. How to ensure that the punch position can be adjusted while not losing the assembly reference? Through long-term exploration and practice, the present application has developed the following two solutions to solve the above problems.

[0050] Method A

[0051] Remove the locating pin and use a reamer to expand the centering pin hole on the upper die seat. The original locating pin is φ6H7 / m6. The single-sided blanking clearance of general thin plate blanking is 0.03-0.05mm. Even if there is a deviation when using the centering punch, it generally does not exceed 0.03mm. Therefore, the amount of hole expansion should not exceed 0.04 in diameter. After hole expansion, the locating pin is used again for assembly and test punching. If deviation is found, there is no need to disassemble it. Since there is a certain gap between the pin and the hole at this time, fine-tuning can be performed. After qualified adjustment, the fixed seat pin hole is matched to complete the assembly. Compared with the original solution, this solution has improved efficiency, but the tolerance of the hole expansion must be strictly controlled. Once it exceeds the tolerance, there may be risks such as biting after reassembly. In view of this, I applied to develop another solution.

[0052] Method B

[0053] 1) Make your own aluminum pins with the same size and specifications as the positioning pins used, and store them in the warehouse for use. The positioning pins originally purchased with the punch are generally made of steel, and are quenched and have a certain hardness. They cannot be adjusted after assembly.

[0054] 2) After the original positioning pin is used for assembly and test punching, if a punch with abnormal clearance is found, remove the positioning pin and replace it with an aluminum pin for reassembly. First, loosen the fixing screw and tap and adjust the fixing seat according to the clearance deviation. Since the pin is used as a reference, the original reference is guaranteed to remain unchanged after reassembly. Since the pin is made of aluminum and is relatively soft, the aluminum pin will produce plastic deformation during fine-tuning of the clearance, thus ensuring the adjustability of the clearance. After fine-tuning and test punching, when the clearance is qualified, the fitter tightens the fixing screw and makes the pin hole of the fixing seat, and the assembly is completed. This solution not only ensures that the reference does not deviate, but also has adjustability, and is easy to operate and risk-free. After trial use, this application has determined method B as the preferred solution and promoted its application.

[0055] Advantages of the present invention:

[0056] Changing the material of the locating pin to aluminum, effectively transferring the reference, and being adjustable, the operation is simple, making it convenient for operators to complete the debugging work faster and more effectively. In addition, this process method is not only applicable to punching punches, but also to other parts with centering functions, such as flanging punches, assembly-type part locating pins, guide pins, etc.

[0057] The present invention also proposes an electronic device, comprising a processor and a memory that is communicatively connected to the processor and is used to store executable instructions for the processor, wherein the processor is used to execute the process method for rapid adjustment of the centering punch.

[0058] The present invention also proposes a server, comprising at least one processor and a memory communicatively connected to the processor, wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the processor so that the at least one processor executes the process method for rapid adjustment of the centering punch.

[0059] The present invention also provides a computer-readable storage medium storing a computer program, wherein the computer program is executed by a processor to implement the process method for rapid adjustment of the centering punch.

[0060] Example 1

[0061] like Figure 3-Figure 4 As shown, Figure 3 This is the general assembly drawing of a punching die. Figure 4 This is a diagram of the upper die and punching punch.

[0062] The centering punch of the present application is a purchased standard part with a steel tail pin. The hardness of the steel tail pin is too high and it is not easy to adjust. The tail pin hole on the installation surface of the punch is processed by CNC and the CNC precision is guaranteed. Most of them can be directly installed and used, but a small number of them still have deviations after installation, resulting in uneven blanking gaps. By adopting the process method of the present application, the steel tail pin on the original component is replaced with an aluminum tail pin, so that the blanking gap can be easily adjusted.

[0063] This application is a special project of Hebei Province's Major Science and Technology Support Program, Innovative Application Scenarios, project number 242Q1803Z.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
