Description

Technical Field

[0001] This utility model relates to the field of stamping dies, specifically a cooling device for a continuous stamping die. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces (stamped parts) of the required shape and size. Stamping and forging both belong to plastic processing (or pressure processing), collectively known as forging and pressing. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. Progressive dies refer to cold stamping dies in which the press uses strip-shaped stamping raw materials to complete multiple stamping processes simultaneously at several different stations on a single die in one stamping stroke. After each stamping stroke, the strip moves a fixed distance once until the product is completed.

[0003] However, the cooling of stamping dies usually relies on the cooling fluid flowing in the internal liquid channels to absorb heat. Traditional cooling requires an external power source to supply the liquid, which results in a large energy consumption for the entire cooling mechanism. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cooling device for continuous stamping dies, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a cooling device for a continuous stamping die, comprising an upper stamping die and a lower stamping die, wherein an upper mold is provided below the upper stamping die, and a lower mold is provided above the lower stamping die; pressure plates are installed on both sides of the upper and lower stamping dies, and a cooling mechanism is provided between the two pressure plates; the cooling mechanism includes: a coolant collecting sleeve, an upper connecting pipe, and a lower connecting pipe; a piston is provided inside the coolant collecting sleeve, and an upper one-way valve is installed inside the piston; a pull-out connecting rod is installed above the support rod, and a lower one-way valve is installed below the coolant collecting sleeve.

[0006] As a further embodiment of this utility model: a support rod is connected between the lower surface of the coolant receiving sleeve and the pressure plate, and joints for connecting the upper and lower connecting pipes are provided on the outer sides of both the upper and lower molds.

[0007] As a further embodiment of this utility model: a return spring is connected between the upper mold and the lower mold, and a guide rod is connected between the upper stamping die and the lower mold.

[0008] As a further improvement of this utility model: both the upper connecting pipe and the lower connecting pipe are connected to the coolant receiving sleeve, and the coolant receiving sleeve is filled with coolant.

[0009] As a further improvement of this utility model, coolant flow pipes are provided inside both the upper mold and the lower mold.

[0010] As a further improvement of this utility model: the coolant collection sleeve is fixedly connected to the pressure plate via the support rod.

[0011] As a further improvement of this utility model: a feeding guide plate is installed on one side of the lower mold, and rollers are arrayed on the upper surface of the feeding guide plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] During the reciprocating motion of the upper mold to the upper position above the lower mold, the connecting rod is pressed to drive the piston to move downwards towards the coolant collection sleeve. This opens the upper one-way valve, allowing the coolant inside the coolant collection sleeve to flow upwards. When the upper stamping die moves upwards, the upper one-way valve closes and the lower one-way valve opens. Therefore, the reciprocating motion does not require an external power source to control the cooling flow for cooling. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4 As shown, this embodiment provides a cooling device for a continuous stamping die, including an upper stamping die 1 and a lower stamping die 2. An upper mold 3 is disposed below the upper stamping die 1, and a lower mold 4 is disposed above the lower stamping die 2. Coolant flow pipes are provided inside both the upper mold 3 and the lower mold 4. Pressure plates 10 are installed on both sides of the upper stamping die 1 and the lower stamping die 2. A cooling mechanism 5 is disposed between the two pressure plates 10. The cooling mechanism 5 includes a coolant receiving sleeve. 501, upper connecting pipe 503, lower connecting pipe 504, coolant collection sleeve 501 is filled with coolant, upper connecting pipe 503 and lower connecting pipe 504 are both connected to coolant collection sleeve 501, piston 506 is installed inside coolant collection sleeve 501, upper one-way valve 507 is installed inside piston 506, pull rod 502 is installed above support rod 505, and lower one-way valve 508 is installed below coolant collection sleeve 501.

[0021] like Figure 2-3 As shown, in this embodiment, a support rod 505 is connected between the lower surface of the coolant collecting sleeve 501 and the pressure plate 10. The coolant collecting sleeve 501 is fixedly connected to the pressure plate 10 through the support rod 505. The upper mold 3 and the lower mold 4 are both provided with joints for connecting the upper connecting pipe 503 and the lower connecting pipe 504. A return spring 8 is connected between the upper mold 3 and the lower mold 4. A guide rod 9 is connected between the upper stamping die 1 and the lower mold 4. A feeding guide plate 6 is installed on one side of the lower mold 4. Rollers 7 are arrayed on the upper surface of the feeding guide plate 6.

[0022] The working principle of this utility model is as follows: During use, cooling mechanisms 5 are installed between the pressure plates 10 on both sides of the entire mold. The upper connecting pipe 503 and the lower connecting pipe 504 on the two cooling mechanisms 5 are connected to the connectors on the outside of the upper mold 3 and the lower mold 4, respectively. After the pull rod 502 inside the coolant collection sleeve 501 is aligned with the pressure plate 10 below the upper stamping mold 1, when the upper stamping mold 1 moves up and down, driving the upper mold 3 to move up and down above the lower mold 4, the pressure plate 10 will press the pull rod 502 to drive the piston 506 to collect the coolant. When the sleeve 501 is pressed downwards, the upper one-way valve 507 is opened, and the coolant inside the coolant collection sleeve 501 flows upwards. When the upper stamping die 1 moves upwards, the upper one-way valve 507 closes and the lower one-way valve 508 opens, drawing the coolant inside the upper die 3 and lower die 4 into the coolant collection sleeve 501. This reciprocating motion allows the coolant inside the upper die 3 and lower die 4 to circulate within the two coolant collection sleeves 501, thus absorbing the heat generated by the upper die 3 and lower die 4 during operation.
