Description

Technical Field

[0001] The utility model relates to the technical field of motor shell processing, in particular to a punching machine for processing the shell of a vibration motor. Background Technique

[0002] At present, when processing the shell and heat dissipation cover of a vibration motor, a punching machine is needed for punching processing to facilitate the forming of workpieces. For example, the patent number CN214235783U discloses a new punching machine for a motor shell, including a base. Above the base, there is a top plate connected by a support rod. A punching device is arranged on the top plate. In the middle of the top surface of the base, there is a mounting seat for fixing a punching die. A placement groove for placing the punching die is arranged on the top surface of the mounting seat. The side of the punching die is connected to the mounting seat by bolts.

[0003] After the applicant's search, it is found that due to the relatively fixed installation of the existing die, the disassembly is very inconvenient. Therefore, in the above solution, the punching die and the mounting seat connected by bolts can be detachably replaced, which can process various types of punching products, improve the application range of the punching machine. The cooperation of the fixing block and the fixing groove can strengthen the structural stability of the die after installation and ensure the stability of the die during punching. The cooperation of the positioning block and the positioning groove can quickly position and install. However, in this solution, it is still necessary to rotate the screws on both sides to strengthen the fixation, and the top is also fixed by bolts. This results in that although it is a detachable design, the disassembly is very laborious and inconvenient. The inconvenient disassembly also makes the hand still located under the punching head during loading and unloading, posing a safety hazard.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a punching machine for processing the shell of a vibration motor is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a punching machine for processing the shell of a vibration motor to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: It includes a stamping table, on the top of the stamping table, a stamping chamber and two U-shaped blocks are installed. On the top of the stamping chamber, a stamping head is installed. On the bottom surface of the cross plate inside the stamping chamber, a first electric push rod is installed. At the bottom of the first electric push rod, a lifting plate is fixed. On the top ends of the two U-shaped blocks, a mold is placed. The lifting plate and the U-shaped blocks are connected with a positioning mechanism. The positioning mechanism includes two first inclined blocks fixed at the bottom of the lifting plate. The inclined surfaces of the first inclined blocks are in contact with the second inclined blocks in the initial state. At the bottom of the second inclined block, a limiting slider is fixed, and the limiting slider slides in the slideway of the U-shaped block. A return spring is connected between the limiting slider and the inner wall of the slideway. On one side of the second inclined block, a positioning block is fixed. The positioning block passes through the U-shaped block and inserts into the side opening of the mold. On the top of the mold, two round mouth grooves are symmetrically fixed, and the cylindrical block at the bottom of the lifting plate inserts into the mouth of the round mouth groove.

[0007] As a further supplement to the above solution, an opening is provided at the center of the lifting plate, and the opening is used for the stamping head to pass through and enter the mold groove during stamping for processing.

[0008] As a further supplement to the above solution, a layer of rubber pads are bonded to the bottom surface of the cylindrical block and the side surface of the positioning block.

[0009] As a further supplement to the above solution, two guide rods are symmetrically fixed on the top of the lifting plate. The guide rods pass through the openings on the cross plate and the top of the stamping chamber and form a sliding connection. A buffer spring sleeved outside the guide rod is connected between the lifting plate and the cross plate.

[0010] As a further supplement to the above solution, two insertion blocks are symmetrically fixed on the bottom surface of the top plate of the mold, and the insertion blocks are inserted into the rod holes on the top of the U-shaped block.

[0011] As a further supplement to the above solution, the bottom of the mold is in contact with the top surface of the support seat. Two second electric push rods are installed at the bottom of the support seat. The second electric push rods pass through the stamping table and are installed on the support frame, and the support frame is fixed to the bottom of the stamping table.

[0012] As a further supplement to the above solution, two square sliders are symmetrically fixed at the bottom of the mold. The square sliders slide in the slideways of the support seat.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. Through the positioning mechanism, the present utility model realizes the fixation of the top and side surfaces of the mold, and the operation is more convenient. It can complete the installation in one step, improve the disassembly and assembly efficiency and save manpower. Moreover, the mold can be taken out for operation during loading and unloading, improving safety.

[0015] 2. In the further optimized design of the placement, removal, loading, and unloading of the mold in the present utility model, during loading, after the workpiece is placed in the mold, the mold is pushed to the innermost end. At this time, the electric push rod two is activated to drive the support base to drive the mold to descend and fit with the top surface of the U-shaped block. At the same time, the insertion block is inserted into the rod hole at the top of the U-shaped block to complete the initial positioning. When taking the material, the support base is raised, and then the mold can be pulled out through the square slide block. In this way, the loading and unloading operations can be carried out conveniently, solving the problem that the loading and unloading manipulator is not safe at the stamping position in the traditional technology, and also avoiding the problem of troublesome handling due to the heavy mold.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0024] Such as Figures 1-6As shown in the figure, it includes a stamping table 1. A stamping chamber 2 and two U-shaped blocks 7 are installed on the top of the stamping table 1. A stamping head 3 is installed on the top of the stamping chamber 2. An electric push rod 5 is installed on the bottom surface of the cross plate 4 inside the stamping chamber 2. A lifting plate 6 is fixed at the bottom of the electric push rod 5. A mold 8 is placed on the top ends of the two U-shaped blocks 7. A positioning mechanism 9 is connected between the lifting plate 6 and the U-shaped blocks 7. The positioning mechanism 9 includes two inclined blocks 91 fixed at the bottom of the lifting plate 6. The inclined surfaces of the inclined blocks 91 are in contact in the initial state. A limit slider 94 is fixed at the bottom, and the limit slider 94 slides in the slideway of the U-shaped block 7. A return spring 95 is connected between the limit slider 94 and the inner wall of the slideway. A positioning block 93 is fixed on one side of the inclined block 93. The positioning block 93 passes through the U-shaped block 7 and inserts into the side opening of the mold 8. Two round mouth grooves 17 are symmetrically fixed on the top of the mold 8, and the cylindrical block 18 at the bottom of the lifting plate 6 is inserted into the notch of the round mouth groove 17.

[0025] Through the above structural design, during installation, the mold 8 containing the workpiece is fitted to the top surfaces of the two U-shaped blocks 7. Then, before stamping, the electric push rod 5 is started to drive the lifting plate 6 to descend. Through the cooperation of the inclined surfaces of the inclined block 91 and the inclined block 93, the two inclined blocks 93 are displaced by the sliding of the limit slider 94. Finally, the positioning block 93 passes through the U-shaped block 7 and inserts into the corresponding notch on the side of the mold 8 to clamp the side of the mold 8. At this time, the cylindrical block 18 also inserts into the notch of the round mouth groove 17 to press the mold 8 to complete the fixation of the top surface of the mold 8. During disassembly, the lifting plate 6 is reset, and the return spring 95 drives the inclined block 93 to reset. In this way, compared with the comparative literature, while achieving the fixation of the top and side surfaces of the mold 8, the operation is more convenient, the installation can be completed in one step, the disassembly and assembly efficiency is improved, manpower is saved, and the mold 8 can be taken out for operation during loading and unloading, improving safety.

[0026] An opening is provided at the center of the lifting plate 6, and the opening is used for the stamping head 3 to pass through and enter the groove of the mold 8 for processing during stamping.

[0027] Through the above structural design, after the installation is completed, the stamping head 3 can be started to descend to stamp the workpiece inside the mold 8. At this time, the opening at the center of the lifting plate 6 facilitates the passage of the stamping head 3, which is very practical.

[0028] A layer of rubber pad is bonded to the bottom surface of the cylindrical block 18 and the side surface of the positioning block 93.

[0029] Through the above structural design, the rubber pad can avoid the problem of wear caused by excessive extrusion force between the cylindrical block 18 and the positioning block 93 and the mold 8, playing a certain protective role.

[0030] Two guide rods 10 are symmetrically fixed on the top of the lifting plate 6. The guide rods 10 pass through the openings at the top of the cross plate 4 and the stamping chamber 2 and form a sliding connection. A buffer spring 11 sleeved on the outside of the guide rods 10 is connected between the lifting plate 6 and the cross plate 4.

[0031] With the above structural design, the guide rod 10 slides in the openings of the cross plate 4 and the stamping chamber 2 to play a guiding role, making the lifting of the lifting plate 6 more stable, while the buffer spring 11 plays a buffering role to avoid damaging the mold 8 due to too fast descent.

[0032] Two inserts 16 are symmetrically fixed to the bottom surface of the top plate of the mold 8, and the inserts 16 are inserted into the rod holes at the top of the U-shaped block 7. The bottom of the mold 8 is in contact with the top surface of the support base 13. Two electric push rods II 14 are installed at the bottom of the support base 13. The electric push rods II 14 pass through the stamping table 1 and are installed on the support frame 15, and the support frame 15 is fixed to the bottom of the stamping table 1. Two square sliders 12 are symmetrically fixed to the bottom of the mold 8, and the square sliders 12 slide in the slideways of the support base 13.

[0033] With the above structural design, in the further optimized design of the placement, removal and loading and unloading of the mold 8, since the mold is heavy, during loading, the mold 8 is initially located on the support base 13, and the square sliders 12 are located in the slideways of the support base 13. After placing the workpiece in the mold 8, the mold 8 is pushed to the innermost end. At this time, the electric push rod II 14 is started to drive the support base 13 to drive the mold 8 to descend and fit with the top surface of the U-shaped block 7. At the same time, the insert 16 is inserted into the rod hole at the top of the U-shaped block 7 to complete the initial positioning. Then, the fixing operation of the mold 8 can be carried out. When taking the material, the support base 13 is raised, and the mold 8 can be pulled out through the square sliders 12. In this way, the loading and unloading operations can be carried out conveniently, solving the problem that the loading and unloading hand is not safe at the stamping position in the traditional technology, and also avoiding the problem of troublesome handling due to the heavy mold.

[0034] Working principle: When working, after placing the workpiece in the mold 8, the mold 8 is pushed to the innermost end. At this time, the electric push rod II 14 is started to drive the support base 13 to drive the mold 8 to descend and fit with the top surface of the U-shaped block 7. At the same time, the insert 16 is inserted into the rod hole at the top of the U-shaped block 7 to complete the initial positioning. Then, before stamping, the electric push rod I 5 is started to drive the lifting plate 6 to descend. Through the cooperation of the inclined surfaces of the inclined surface block I 91 and the inclined surface block II 93, the two inclined surface blocks II 93 are displaced by the sliding of the limit slider 94. Finally, the positioning block 93 passes through the U-shaped block 7 and is inserted into the corresponding notch on the side of the mold 8 to clamp the side of the mold 8. And at this time, the cylindrical block 18 is also inserted into the notch of the round mouth groove 17 to press the mold 8 to complete the fixation of the top surface of the mold 8. Then, the stamping head 3 is started to descend to stamp the workpiece inside the mold 8. At this time, the central opening of the lifting plate 6 is convenient for the stamping head 3 to pass through. After stamping is completed, the lifting plate 6 is reset, and the reset spring 95 drives the inclined surface block II 93 to reset. When taking the material, the support base 13 is raised, and the mold 8 can be pulled out through the square sliders 12. In this way, one stamping operation is completed. The utility model has good practicability, is simple and convenient to use, and is worthy of popularization and use.
