Description

A stamping and forming equipment for automobile wiring terminals

Technical Field

The invention relates to the technical field of punching and forming connection terminals, in particular to a punching and forming device for automobile connection terminals.

Background Art

The terminal block is an accessory product used to achieve electrical connection and is a type of connector. When using existing technology to prepare the terminal block, it is usually necessary to punch copper, aluminum, copper alloy, or copper-aluminum alloy into conductive sheets of the required shape and size. It is also necessary to punch the connection position with the wire into a ring shape to facilitate the connection between the terminal block and the wire.

In the process of stamping the conductive sheet into a terminal, it is necessary to position and clamp it to improve the stamping accuracy. The existing positioning method is to use a downward pressure plate to press on the upper part of the conductive sheet to position it. Since the friction between the conductive sheet and the pressure plate is not stable, the conductive sheet will be offset during the stamping process, resulting in inaccurate stamping position and reduced stamping accuracy. In addition, for the stamping process of E-shaped terminals, it is necessary to replace the matching support plate according to the conductive sheets of different spacing specifications. It cannot be quickly adjusted according to the E-shaped conductive sheets of different specifications, which reduces the applicability of the device.

Summary of the invention

DETAILED DESCRIPTION

In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

Please refer to Figure 1. The present invention provides a technical solution: a stamping and forming device for automobile wiring terminals, comprising a workbench 1 and an inverted U-shaped frame 2 fixedly connected to the upper part of the workbench 1, the upper end surface of the workbench 1 is fixedly connected to a load-bearing plate 3 through a pillar, a plurality of support plates 5 are equidistantly installed on the front of the load-bearing plate 3 through a distance adjusting member 4, a plurality of stamping mechanisms 6 corresponding to the support plates 5 are installed on the upper end surface of the workbench 1, a lower end surface of the transverse section of the inverted U-shaped frame 2 is fixedly connected to a pressing plate 8 through an electric telescopic rod 7, and arc-shaped sheets are fixedly connected to the left and right sides of the longitudinal section of the pressing plate 8.

Please refer to Figures 3 and 4. In this embodiment, the distance adjusting member 4 includes a strip-shaped through groove 41 opened on the front end surface of the bearing plate 3, a slider 42 slidably connected to the inside of the strip-shaped through groove 41, a sliding column 43 slidably connected to the front part of the slider 42, an elastic ring 10 is fixedly connected to the outside of the sliding column 43, an annular groove 11 is opened inside the slider 42 where the sliding column 43 penetrates, a support plate 5 is fixedly connected to the front end of the sliding column 43, a serrated strip plate 44 is fixedly connected to the upper and lower opposite side groove walls of the strip-shaped through groove 41, and two serrated strip blocks 45 for cooperating with the serrated strip plates 44 are symmetrically fixedly connected to the outside of the sliding column 43, and the cross-sections of the front part of the serrated strip plate 44 and the rear part of the serrated strip block 45 are both in the shape of a pointed cone.

Before punching the conductive sheet, the spacing of the support plates 5 is adjusted by the spacing adjusting member 4, so that the spacing of the support plates 5 matches the spacing of the branch segments in the E-shaped conductive sheet to be processed, and the support plate 5 is pulled forward to drive the slide post 43 to move forward, and the slide post 43 then drives the elastic ring 10 to disengage from the annular groove 11, and at the same time, the serrated strip 45 also moves forward with the slide post 43 to separate from the serrated strip plate 44, and then the support plate 5 can be slid in the strip through groove 41 to adjust the position between the support plates 5, so as to be suitable for placing E-shaped conductive sheets of different specifications and sizes, and then the support plate 5 is pushed backward to drive the slide The column 43 moves backward, and the sliding column 43 then drives the serrated strip 45 to move backward and snap into the serrated strip plate 44, thereby limiting and locking the support plate 5 after the position is adjusted. Since the cross-sections of the front part of the serrated strip plate 44 and the rear part of the serrated strip 45 are both in the shape of a pointed cone, the pointed cone sides of the serrated strip 45 can play a guiding role during the backward movement, thereby facilitating the snapping of the serrated strip 45 and the serrated strip plate 44. At the same time, the backward movement of the sliding column 43 will also drive the elastic ring 10 to snap into the annular groove 11, so that the sliding column 43 is stuck in the slider 42, thereby locking the position of the sliding column 43 after the movement.

Please refer to Figures 1 and 2. In this embodiment, a positioning mechanism 9 is provided on the lower end surface of the pressure plate 8. The positioning mechanism 9 includes a push rod 92 slidably arranged at the lower part of the pressure plate 8 through a sliding assembly 91, a push spring 93 fixedly connected to the lower part of the sliding assembly 91 and the outer wall of the push rod 92 through a fixing block and simultaneously sleeved on the outside of the push rod 92, a plurality of connecting rods 94 hinged to the lower part of the outer wall of the push rod 92 at equal intervals in the circumferential direction through lugs, and a positioning block 95 hinged at the lower end of the connecting rod 94. The sliding assembly 91 includes a strip groove 911 opened on the lower end surface of the pressure plate 8, a slide plate 912 slidably connected to the inside of the strip groove 911, the push rod 92 penetrates and is slidably connected to the inside of the slide plate 912, and the front and rear sides of the slide plate 912 are provided with installation grooves, and the inside of the installation groove is fixedly connected with a resistance block fitted on the groove wall of the strip groove 911 through a spring telescopic column.

The position of the push rod 92 is adjusted by using the sliding assembly 91 according to the position of the through hole on the conductive sheet, so that the push rod 92 is located just above the corresponding through hole, and the sliding slide 912 drives the push rod 92 to move until the push rod 92 slides to just above the through hole, and the spring telescopic column is used to push the abutment block to fit tightly against the groove wall of the strip groove 911 to increase the friction between the slide plate 912 and the strip groove 911 to prevent the slide plate 912 from sliding randomly after moving, and then the conductive sheet is placed on the carrier plate 3 and the support plate 5, and then the electric telescopic rod 7 is controlled to extend to drive the pressing plate 8 to descend, and the pressing plate 8 descends and The push rod 92 is pushed down by the push spring 93, and then the positioning block 95 is pushed by the connecting rod 94 to abut against the supporting plate 3. Since the connecting rod 94 gradually tilts away from the axis of the push rod 92 from top to bottom, the push rod 92 will press the connecting rod 94 to expand outward during its downward movement. The connecting rod 94 then pushes the positioning block 95 to move outward until the positioning block 95 abuts against the side wall of the through hole. Each positioning block 95 corresponding to the through hole abuts against the side wall of the through hole, which firmly limits the conductive sheet and avoids the displacement of the conductive sheet during the stamping process. Finally, the pressure plate 8 completely abuts against the upper part of the conductive sheet.

Please refer to Figure 1. In this embodiment, the stamping mechanism 6 includes a bracket 61 slidably connected to the upper part of the workbench 1, a U-shaped plate 63 fixedly connected to the upper part of the bracket 61 by an electric telescopic push rod 62, and a U-shaped fork 65 fixedly connected to the left and right opposite sides of the U-shaped plate 63 by an electric telescopic column 64. After the conductive sheet is positioned, the bracket 61 is slidably adjusted according to the position of the longitudinal section of the E-shaped conductive sheet, so that the bracket 61 is located directly below the longitudinal section of the conductive sheet, and then the electric telescopic push rod 62 is extended to drive the U-shaped plate 63, and the U-shaped plate 63 then drives the U-shaped fork 65 to rise, and the U-shaped fork 65 is moved until the conductive sheet gradually deforms and bends to fit the lower part of the arc-shaped sheet, and then the electric telescopic push rod 62 stops extending, and the electric telescopic column 64 is controlled to extend to drive the U-shaped fork 65 to move horizontally, and the U-shaped fork 65 then moves the conductive sheet to be bent and sleeved outside the pressing plate 8, thereby completing the stamping and forming of the terminal.

During operation, firstly, the spacing of the support plate 5 is adjusted by the spacing adjusting member 4 according to the spacing of the longitudinal segments in the E-shaped conductive sheet, so that the position of the support plate 5 matches the branches of the E-shaped conductive sheet, which is suitable for placing conductive sheets of different specifications and sizes. Then, the position of the push rod 92 in the positioning mechanism 9 is adjusted by the sliding assembly 91 according to the position of the through hole in the conductive sheet, so that the push rod 92 is located directly above the through hole corresponding to it. Then, the pressing plate 8 is driven to descend by the electric telescopic rod 7. During the descent of the pressing plate 8, the positioning mechanism 9 operates, and the connecting rod 94 expands outward to push the positioning block 95 against the inner wall of the through hole in the conductive sheet. Then the pressing plate 8 is against the upper part of the conductive sheet, thereby completing the positioning and clamping of the conductive sheet. Finally, the stamping mechanism 6 is controlled to operate to stamp the conductive sheet into a terminal.
