Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a side punching die for automotive sheet metal. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). In the production of automotive parts, due to the irregular shape of automotive parts, it is necessary to perform side punching on the automotive parts.

[0003] A search revealed a Chinese patent (application number "202222176066.9") that discloses "a side punching mold for automotive parts." This side punching mold includes a base with a limiting frame fixedly installed on its top. A U-shaped plate is also fixedly installed on the top of the base. A side punching mechanism and a fixing mechanism are installed on the inner side of the U-shaped plate. The side punching mechanism is connected to the fixing mechanism. The side punching mechanism includes two symmetrically located sliding plates on the top of the base. A punch rod is fixedly installed on the side of each sliding plate that is close to the other, and a cutting tool is fixedly installed on the side of each punch rod that is close to the other. Channels are provided on both sides of the sliding plates. However, this side punching mold does not secure the parts during punching, requiring workers to hold the parts while punching. This increases the risk of hand contact with the sliding plates, resulting in low safety. Utility Model Content

[0004] This utility model provides a side punching mold for automotive sheet metal, which solves the problem of low safety in the side punching mold proposed in the prior art, where workers need to hold the parts to punch the parts, and their hands are likely to come into contact with the slide plate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A side punching die for an automotive sheet metal part includes a mounting plate, a storage mechanism, and an extrusion base. The mounting plate has two extrusion mechanisms on its top. Each extrusion mechanism includes a mounting frame with an opening on its top outer wall, two fixing rods bolted to the top outer wall of the mounting plate, right-angled trapezoidal extrusion blocks slidably mounted on the outer walls of the two fixing rods, and two first return springs respectively sleeved on the outer walls of the two fixing rods. The mounting plate also has two transmission mechanisms on its top. Each transmission mechanism includes a mounting base bolted to the top outer wall of the mounting plate, two connecting rods bolted to one side outer wall of the mounting base, and an outer wall... The device includes a fixed base with a channel, a right-angled trapezoidal transmission block slidably mounted on the outer wall of two connecting rods, and two second return springs respectively sleeved on the outer wall of the two connecting rods. Each of the two transmission blocks has a punching assembly on one side. The punching assembly includes a connecting seat bolted to the outer wall of one side of the transmission block, several punching rods bolted to the outer wall of one side of the connecting seat, two third return springs respectively sleeved on the outer wall of two of the punching rods, and a fixed plate slidably mounted on the outer wall of the several punching rods. A fixing mechanism is provided at the top center of the mounting plate. The fixing mechanism includes a fixing frame with magnets embedded on both outer walls.

[0007] Preferably, the storage mechanism includes a base plate, several support plates respectively bolted to the top outer wall of the base plate, a first side plate bolted to the top outer wall of the base plate, two second side plates respectively bolted to the top outer wall of the base plate, and a collection drawer slidably sleeved between two of the support plates. The support plates, the first side plates, and the two second side plates are respectively bolted to the bottom outer wall of the mounting plate, and the top of the collection drawer abuts against the bottom outer wall of the mounting plate.

[0008] Preferably, the mounting frame is bolted to the top outer wall of the mounting plate, and two fixing rods pass through and are bolted to the outer wall of the mounting frame.

[0009] The above solution uses multiple support plates, a first side plate, and two second side plates to support the mounting plate. Waste generated during punching falls into the collection drawer, which can be pulled out using the handle to dispose of the waste.

[0010] Preferably, the mounting plate has two fixing grooves on its top outer wall, and two fixing seats are respectively connected to the two fixing grooves by bolts. The fixing seats have two fixing holes on one side outer wall, and one end of each of the two connecting rods is respectively connected to the two fixing holes by bolts.

[0011] Preferably, one end of the connecting seat is slidably sleeved in the channel, and the two ends of the third reset springs are respectively welded to the outer wall of the connecting seat and the fixing plate on opposite sides, and the fixing plate is slidably sleeved in the channel.

[0012] Preferably, the mounting plate has a mounting groove on the top outer wall and a discharge port on the bottom inner wall of the mounting groove. The fixing frame has several through holes on both sides of the outer wall. The fixing frame is connected to the mounting groove by bolts, and several reinforcing plates are welded to the inner wall of the fixing frame.

[0013] Preferably, the extrusion seat is slidably sleeved on the upper outer wall of the four fixed rods, and the bottom of the extrusion seat abuts against the top outer wall of the two extrusion blocks.

[0014] The above scheme uses magnets on both sides of the fixed frame to attract and fix the parts. The press drives the extrusion seat to descend, and the extrusion seat extrudes two extrusion blocks. At the same time, the two extrusion blocks extrude two transmission blocks, causing the transmission blocks to move along two connecting rods. This, in turn, moves the connecting seat, several punching rods, and the fixing plate. The fixing plate contacts the parts, and then the punching rods move to punch holes in the parts. Simultaneously, the fixing plate extrudes two third return springs. Under the tension of the third return springs, the fixing plate extrudes and fixes the parts.

[0015] The beneficial effects of this utility model are as follows:

[0016] Magnets on both sides of the fixed frame attract and fix the parts. The press drives the extrusion seat to descend, which causes the connecting seat, several punching rods, and the fixed plate to move. The fixed plate contacts the parts, and then the punching rods move to punch the parts. At the same time, the fixed plate presses the two third return springs. Under the tension of the third return springs, the fixed plate presses and fixes the parts. This allows the parts to be attracted and fixed during punching, preventing the hands from coming into contact with the mold and improving safety. Attached Figure Description
