Description

Technical Field

[0001] The invention belongs to the technical field of trimming machines and relates to a hot punching online trimming mechanism. Background Art

[0002] "Red punching" is a new term, and it is difficult to find its origin in the dictionary. Because the red punching process is an advanced professional process that has just been developed on the basis of modern precision forging and hot extrusion. With the advancement of society and the development of science and technology, the machinery industry has put forward new mechanical strength requirements for mechanical parts. There are generally two methods to improve mechanical strength. One is to change the material of the parts, and the other is to change its processing method. The red punching process is one of the effective methods to improve the mechanical properties of parts by changing the processing method. Therefore, like its forging process, it has strong vitality and good development prospects. The red punching process heats the metal blank and places it in the mold for forming like the precision forging process, but red punching is generally formed in one time except for large red punching parts, while precision forging is generally formed by several pressures.

[0003] Products formed by hot stamping generally form flash. In the prior art, removing the flash of the product requires two steps. First, the hot stamping product needs to be taken out of the hot stamping machine and then manually sent to the trimming machine for trimming. The degree of automation is low and it is time-consuming and labor-intensive.

[0004] In order to overcome the shortcomings of the prior art, people have proposed various solutions through continuous exploration. For example, a Chinese patent discloses an automatic punching and scrapping equipment with a protective structure for the production of eyeglass packaging boxes [application number: 202021912454.3], which includes a support seat and a punching base, a conveyor belt is arranged on the top of the support seat, a punching piece is arranged at the middle end of the top of the punching die seat, and a punching groove is opened on the inner side of the top of the punching die seat, the punching base is placed on the top of the fixed plate, and a lower infrared grating is arranged on the top of the outer side of the punching base, an upper infrared grating is connected to the bottom side of the punching top plate, and a punching knife is connected to the middle end of the bottom of the punching seat, but the above-mentioned problems also exist.

[0042] The transverse driving assembly on the discharge hand slide pedestal 26 can drive the transverse slide rail 8 to move back and forth in the horizontal direction, thereby driving the trimming mold to switch back and forth between the red punch in the forming area and the lower side of the trimming top mold. The transverse sliding block 11 can limit the transverse slide rail 8.

[0043] Specifically, the transverse driving assembly 207 includes a rack 10 fixed on the transverse slide rail 8, and a driving gear 9 is provided on the rack 10, and the driving gear 9 is connected to the driving motor 6. The driving motor 6 can drive the driving gear to rotate, and the rotation of the driving gear can drive the rack to move, and the movement of the rack can drive the transverse slide rail to reciprocate in the horizontal direction.

[0047] The lifting driver 27 can drive the lifting screw to rotate, and the rotation of the lifting screw can drive the lifting slider to lift in the vertical direction. The lifting of the lifting slider in the vertical direction can drive the two limit sliders to lift in the vertical direction. The lifting of the limit slider can drive the slide connecting plate 24 to lift in the vertical direction. The vertical slide rail can limit the limit slider to prevent the slide connecting plate 24 from deviating during movement.

[0048] The working principle of the present invention is as follows: the hot punching machine punches the product at the trimming die in the forming area and can shape the product to be trimmed at the trimming forming groove 18.

The four trimming forming slots are arranged in a rectangular array to prevent the flash of the products from affecting each other. The length of the trimming ejector 19 is greater than the depth of the trimming forming slot 18 to ensure that the products can be ejected from the trimming forming slot.

[0051] The chip guard 22 can prevent the flying edges cut from the product from splashing and causing injuries to the operator or affecting environmental hygiene. The secondary guide assembly 204 can further limit the trimming top die to prevent the trimming top die from being offset in the travel position after being subjected to the recoil force when being pressed down.

The two through holes on the trimming mechanism seat correspond to two trimming forming through grooves respectively. The products ejected from the trimming forming through grooves can fall from the through holes and be uniformly guided to the product output mechanism or product collection device through the discharge hopper.

[0052] The transverse driving assembly on the discharge hand slide pedestal 26 can drive the transverse slide rail 8 to reciprocate in the horizontal direction, thereby driving the trimming die to switch back and forth between the red punch in the forming area and the lower side of the trimming top die. The transverse sliding block 11 can limit the transverse slide rail 8.
