DETAILED DESCRIPTION

[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the present invention.

[0021] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, as follows:

[0022] A device for processing multiple concave point molds at the same time comprises a base 1, a core rod connecting seat 2 is provided above the base 1, a core rod connecting plate 3 is connected to one side of the core rod connecting seat 2, and a concave point punch shaft sleeve 4 is connected to the other side, a plurality of groups of dotting punches 5 are penetrated around the outer circumference of the concave point punch shaft sleeve 4, a dotting core rod 6 is penetrated in the middle, one end of the dotting core rod 6 is detachably connected to the core rod connecting seat 2, grooves 7 are respectively provided on the outer wall of the dotting core rod 6 corresponding to one end of the dotting punch 5, a rotating shaft sleeve 8 is sleeved on the outer side of the concave point punch shaft sleeve 4, and an inner wall of the rotating shaft sleeve 8 is respectively provided with extension grooves 9 with an arc-shaped structure corresponding to the dotting punch 5, a rotating rod 10 is extended at one end of the outer wall, an adjusting limit seat 11 is penetrated by the rotating rod 10, a reset spring 12 is provided inside the adjusting limit seat 11 corresponding to the lower part of the rotating rod 10, and a pressing punch 13 is movably provided above the rotating rod 10.

[0023] Furthermore, the central axes of the dotting core rod 6 and the concave punch sleeve 4 are located on the same straight line, and the outer wall of the dotting core rod 6 and the inner wall of the concave punch sleeve 4 are arranged relative to each other in a non-contact manner.

[0024] Furthermore, one end of the dot punch 5 passes through the inner wall of the concave punch sleeve 4, and a compression spring 14 is provided between the dot punch 5 and the concave punch sleeve 4 for limiting position.

[0025] Furthermore, a safety shield 15 is provided on the upper cover of the base 1 , and the safety shield 15 has openings 16 corresponding to the pressing punch 13 , one end of the concave punch sleeve 4 and the core rod connecting seat 2 , and the core rod connecting seat 2 is embedded in one side of the safety shield 15 .

[0026] Furthermore, one end of the dot punch 5 corresponding to the extension groove 9 is in a semi-spherical structure.

[0027] Furthermore, the adjustment limit seat 11 is a square ring structure.

[0028] Furthermore, an adjusting screw 17 is provided on the top end of the adjusting limit seat 11 corresponding to the rotating rod 10 .

[0029] Furthermore, the bottom end of the adjustment limit seat 11 is fixedly connected to the base 1 .

[0030] Furthermore, four groups of dot punches 5 are provided, which are in a cross structure and surround and penetrate the concave dot punch sleeve 4.

[0031] like Figure 2 As shown, combined with the product processing requirements, the action analysis is carried out. When the force Q1 is pressed down, it drives the rotating sleeve 8 to rotate Q2. Under the action of Q2, Q3 prompts multiple dotting punches 5 in the mold to move forward in a coordinated manner, thereby completing multiple concave point processing at one time.

[0032] The working principle of the present invention is as follows: when the pressing punch 13 moves downward, it pushes the rotating sleeve 8 and drives the dotting punch 5 to punch a concave shape toward the dotting core rod 6. At this time, the reset spring 12 and the compression spring 14 are compressed by external force at the same time. When the pressing punch 13 completes the downward movement and resets upward, the external force of the reset spring 12 and the compression spring 14 disappears, the spring rebounds, and at the same time pushes the rotating sleeve 8 and the dotting punch 5 to reset, thereby realizing the simultaneous dotting processing of multiple concave points.

[0033] According to product requirements, in order to ensure the consistency of the depth of multiple concave points processed, the dotting punch 5 needs to be designed to have the same total length, and the rotating sleeve that drives the dotting punch 5 to work is an integrated spinning rotating sleeve with multiple spinning ports; since the rotating sleeve 8 is not connected to the pressing punch 13, after the Q1 force is pressed down to reset the processing, the rotating sleeve 8 and the dotting punch 5 have no power, and a compression spring 14 needs to be used for power reset; in order not to be limited by the processing length and product length, the device needs to be designed as a horizontal processing structure.

[0034] The present invention utilizes the principle of mechanical linkage. When the machine tool equipment presses down the punch 13, it links with the rotating shaft sleeve 8 to drive multiple dotting punches 5, so that the processing of multiple concave points can be completed in one pressing action, thereby meeting the product quality requirements while improving production efficiency, shortening the production cycle, and improving the cost advantage of the enterprise; the present invention has a compact structure, is easy to disassemble, and is convenient and quick to clamp, and has a relatively low manufacturing cost; the products processed by the present invention ensure the consistency of the concave point length and the circumferential uniformity, and avoid the problems of poor concave point length and poor appearance.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
