Description

Technical Field

[0001] The utility model belongs to the technical field of stamping equipment, and in particular relates to an automatic resistor sheet stamping equipment. Background Art

[0002] The resistor is a passive component, and its main function is to reduce voltage and limit current. The known resistor uses an alumina crystal substrate, printed with a metal thick film conductor, and coated with a glass uranium protection chip on the outer layer. Its shape is as disclosed in the publication (announcement) number CN216793405U, a new type of metal resistor and its resistor.

[0003] When processing this type of resistor, it is necessary to use a processing machine to punch out isolation grooves that are spaced apart on it. However, existing processing machines generally use multiple sets of blades on a mold to punch the resistor at one time. In this processing method, after the punch punches the resistor, the resistor may be stuck in the mold below, or the resistor may be mounted on the punch. When the punch rises, it will drive the product up, making demolding difficult and affecting production efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide an automated resistor sheet stamping device to solve the problems mentioned in the background technology.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] An automated resistor sheet stamping device comprises a base, wherein a high-efficiency stamping table and an anti-stuck punch are installed on the upper side of the base;

[0007] The high-efficiency stamping table includes a circular turntable, which is rotatably mounted on the upper side of the base, a lower template is provided on the upper side of the circular turntable, the number of the lower templates is several and distributed circumferentially, a plurality of push rods distributed linearly are vertically slidably mounted in the middle of the lower template, a roller is rotatably mounted on the lower side of the push rod, a push rod top platform which is low in front and high in the back is installed on the lower side of the circular turntable, the roller abuts against the push rod top platform, and an arc-shaped waste opening is provided on the front side of the push rod top platform;

[0008] The anti-stuck punch is located on the upper front side of the high-efficiency stamping table, and the anti-stuck punch includes an upper pressure plate, and a lower push plate is vertically slidably installed on the lower side of the upper pressure plate. The upper pressure plate and the lower push plate match each other and match the lower template together.

[0014] An annular baffle is also installed on the upper side of the push rod top platform.

[0015] The cooperation between the upper pressing plate and the lower pushing plate can prevent the resistor from being set on the punch and rising when processing the resistor.

The design of the semicircular cross-section of the push rod prevents the push rod from rotating during work and changing the working angle of the roller. The annular baffle separates the arc-shaped waste opening from the push rod to prevent the waste generated by stamping from entering the running track of the roller and affecting the push rod.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1-9 As shown, an automated resistor sheet stamping device comprises a base 1, on the upper side of which a high-efficiency stamping table and an anti-stuck punch are installed;

[0029] The high-efficiency stamping table includes a circular turntable 2, which is rotatably mounted on the upper side of the base 1, a lower template 3 is opened on the upper side of the circular turntable 2, the number of the lower templates 3 is several and distributed circumferentially, a plurality of push rods 4 distributed linearly are vertically slidably mounted in the middle of the lower template 3, a roller 5 is rotatably mounted on the lower side of the push rod 4, a push rod top platform 6 which is lower in front and higher in the back is installed on the lower side of the circular turntable 2, the roller 5 abuts against the push rod top platform 6, and an arc-shaped waste opening 7 is opened on the front side of the push rod top platform 6;

[0030] The anti-stuck punch is located on the upper front side of the high-efficiency stamping table. The anti-stuck punch includes an upper pressure plate 8, and a lower push plate 9 is vertically slidably installed on the lower side of the upper pressure plate 8. The upper pressure plate 8 and the lower push plate 9 match each other and match the lower template 3 together. A number of matching ears 10 are provided on the sides of the upper pressure plate 8 and the lower push plate 9. A limiting slide bar 11 is installed between the ears 10. A spring 12 is sleeved on the outer side of the limiting slide bar 11, and a straight groove matching the ear 10 is opened on the side of the lower template 3.

[0031] When in use, the unprocessed resistor is placed in the lower template 3 on the right side of the anti-stuck punch, and the circular turntable 2 rotates clockwise to rotate the unprocessed resistor to just below the anti-stuck punch. The protruding mold parts in the anti-stuck punch are mainly concentrated on the lower side of the upper pressure plate 8, and the surface of the lower push plate 9 is relatively flat. During punching, the upper pressure plate 8 of the anti-stuck punch drives the lower push plate 9 to punch downward together, and the punched waste is discharged from the arc-shaped waste port 7. After the unprocessed resistor is punched into the designed shape, the anti-stuck punch is retracted upward, and under the action of the spring 12, the lower push plate 9 presses the resistor, and the upper pressure plate 8 is pulled away from the upper side of the resistor, and then pushed down and lifted together with the upper pressure plate 8. The straight groove and the lifting ear 10 cooperate to ensure that the anti-stuck punch is normally engaged with the lower template 3, and the limit slide bar 11 is used to limit the position of the lower push plate 9 sliding up and down to prevent lateral displacement.

[0032] When a resistor sheet is processed, the circular turntable 2 rotates clockwise again, and the above stamping steps are repeated. At the same time, during the rotation of the circular turntable 2, the push rod 4 on the upper side of the roller 5 is lifted up by the roller 5 according to the shape of the push rod top platform 6, and the resistor sheet processed in the lower template 3 is ejected.

[0033] The cooperation between the upper pressure plate 8 and the lower push plate 9 can prevent the resistor from being mounted on the punch and rising when processing the resistor. The cooperation between the push rod 4 and the lower template 3 can avoid the difficulty in demolding the resistor and the lower template 3, and can also make the resistor automatically demolded after the stamping is completed. At the same time, the design of the circular turntable 2 enables the stamping equipment to load and unload materials at the same time during operation, thereby improving production efficiency.

[0034] A hydraulic press 14 is installed on the upper side of the anti-stuck punch, a hydraulic rod is vertically installed in the middle of the hydraulic press 14, the output end of the hydraulic rod is transmission-connected to the upper pressure plate 8, guide rods 16 are installed on both sides of the upper pressure plate 8, and the guide rods 16 are slidably connected to the hydraulic press 14.

[0035] The hydraulic rod provides power for the anti-stuck punch, and the guide rod 16 is used to prevent the hydraulic rod from deviating due to uneven force during punching, thereby avoiding damage to the anti-stuck punch, the lower template 3 and the hydraulic rod.

[0036] A motor 17 is installed at the lower side of the circular turntable 2 , and the output shaft of the motor 17 is drivingly connected to the circular turntable 2 .

[0037] The motor 17 is used to control the rotation of the circular turntable 2, so that the lower template 3 can be more accurately aligned with the anti-stuck punch while reducing the labor intensity of the staff.

[0038] The opening of the lower template 3 is provided with a chamfer; the chamfer design enables the unprocessed resistor sheet to be placed in the lower template 3 more conveniently.

[0039] One end of the axis of the roller 5 coincides with the center of the circular turntable 2 .

[0040] The design that the axis of the roller 5 coincides with the center of the circular turntable 2 can reduce the wear of the roller 5 by the push rod top platform 6 when the circular turntable 2 rotates, thereby extending the service life of the roller 5.

[0041] The cross section of the push rod 4 is semicircular.

[0042] The design of the semicircular cross section of the push rod 4 prevents the push rod 4 from rotating during operation and changing the working angle of the roller 5 .

[0043] An annular baffle 18 is also installed on the upper side of the push rod top platform 6.

[0044] The annular baffle 18 separates the arc-shaped waste opening 7 from the push rod 4 to prevent the waste generated by stamping from entering the running track of the roller 5 and affecting the push rod 4.

[0045] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
