Technical Field
[0001] The present application relates to the technical field of stamping dies, and in particular to a countersink stamping die for aluminum skeletons. Background Art
[0002] The engine gasket is placed between the engine block and the cylinder head to seal the engine. Usually, the engine gasket includes a sheet-like metal frame and rubber layers attached to opposite sides of the metal frame. According to actual needs, the metal frame is generally an iron frame or an aluminum frame, wherein the iron frame is made of stainless steel coil by stamping, and the aluminum frame is made of aluminum alloy coil by stamping.
[0003] Reference Figure 1 The aluminum frame includes an aluminum frame body 01 , and a plurality of through holes 011 are opened through the aluminum frame body 01 as needed for easy installation, and two countersunk holes 012 are penetrated through the aluminum frame body 01 .
[0004] In the prior art, the above-mentioned aluminum frame is prepared by firstly using a shearing machine to cut the aluminum plate into strips close to the contour of the aluminum frame; then the aluminum frame contour and the through holes are punched out on the strips through a composite mold; for the countersunk holes on the aluminum frame, it is necessary to further punch the semi-finished product of the aluminum frame through a punch press. After completing the punching process, the semi-finished product of the aluminum frame is transferred to a milling machine, and the semi-finished product of the aluminum frame is clamped twice to further punch holes in the countersunk grooves on the aluminum frame.
[0005] The above-mentioned preparation process of the aluminum frame is relatively complicated, and it is necessary to move the materials many times to transfer them to different equipment for sinking and punching the aluminum frame. However, each time the equipment is changed, it needs to be recalibrated and positioned, which not only increases the workload of the staff, but also greatly reduces the stamping preparation efficiency of the aluminum frame.

[0008] A countersink stamping die for an aluminum skeleton, comprising a fixed die plate and a movable die plate arranged above the fixed die plate, the fixed die plate being provided with a fixed ring seat, and a circle of positioning strips for limiting the position of the aluminum skeleton body is provided on the fixed ring seat corresponding to the contour of the aluminum skeleton body, a stamping die set is also provided on the movable die plate and the fixed die plate corresponding to the countersinks to be stamped on the aluminum skeleton body, the stamping die set comprises a lower die arranged on the fixed die plate and an upper die arranged on the movable die plate, the lower die being arranged in series in the fixed ring seat, and a countersink punch for punching the countersink is provided on the lower die, and a groove punch for stamping the groove is correspondingly provided on the upper die, and when the fixed die plate and the movable die plate are in a mold closing state, the countersink punch and the groove punch are arranged in abutment with each other.
[0009] By adopting the above technical scheme, the operator installs the fixed template and the movable template on the punching machine, and then places the aluminum skeleton body plate with through holes punched out in the groove surrounded by the positioning strips. By controlling the punching machine to drive the movable template to press down, the corresponding groove punches and countersink punches on the upper and lower dies are butted against each other, and countersinks are punched out on the aluminum skeleton body plate, thereby reducing multiple material handling links, reducing the occurrence of work-related injuries, improving the stability of the aluminum skeleton body during the countersinking process, and also improving the work efficiency of aluminum skeleton countersinking punching.
[0010] Optionally, a slide groove is opened on both sides of the top wall of the lower mold along the length direction of the aluminum frame body, and a clamping module is slidably arranged in the two slide grooves. The opposite side walls of the two clamping modules are arranged corresponding to the outer contour of the aluminum frame body, and a limit plate is arranged on the bottom wall of the upper mold corresponding to each slide groove. The two limit plates are located on the opposite sides of the two clamping modules, and when the fixed mold plate and the movable mold plate are in a mold closing state, the limit plates are inserted into the corresponding slide grooves and push the clamping modules to make the two clamping modules clamp the aluminum frame body in the middle.
[0011] By adopting the above technical solution, during the countersink punching process, the portion of the aluminum frame body to be countersunk is first placed between the two clamping modules, and then the movable die seat is driven downward. During the pressing process, the limit plate on the upper die is first inserted into the slide groove, and the two clamping modules are driven to slide relative to each other until the aluminum frame body is clamped stably, thereby improving the stability effect during the countersink punching process.

[0016] Optionally, guide surfaces are arranged on the bottom walls on opposite sides of the two limiting plates.
[0017] By adopting the above technical solution, the limit plate plays a role of resisting and pushing the clamping module to slide during the process of being inserted into the slide groove.

[0018] Optionally, top support rods are arranged on the opposite sides of the two clamping modules along the length direction perpendicular to the aluminum frame body, each of the top support rods is slidably passed through the side wall of the lower mold, and the rod ends extending out of the side wall of the lower mold are sleeved with end rings, and each rod section extending out of the side wall of the lower mold is sleeved with a spring, the spring abuts between the end ring and the outer wall of the lower mold, and an avoidance groove is provided at the bottom of the limit plate corresponding to the limit rod.
[0019] By adopting the above technical solution, the setting of the top support rod can reduce the possibility of the clamping module falling out of the slide groove during the clamping process. When the movable template moves upward, the limit plate releases the restriction on the clamping module. Through the elastic recovery property of the spring, the two clamping modules move away from each other.

[0022] Optionally, a scale mark for prompting is provided on the top wall of the fixed template.
[0023] By adopting the above technical solution, the electroplated scale markings on the top wall of the fixed template make it easier for the staff to accurately correspond to the placement direction of the aluminum frame body plate, thereby improving the work efficiency of the aluminum frame stamping preparation.
