Description

Technical Field

[0001] This utility model relates to the field of elevator parts processing technology, and in particular to an elevator hanging plate punching and trimming mold. Background Technology

[0002] According to the patent document with publication number CN221246694U, a punching and trimming mold for elevator hanging plates is disclosed. The mold, driven by an external power mechanism, causes the punch trimming template, the fixed pin plate, and the punching pin to press down. The punching pin, in conjunction with the through hole of the lower mold, punches holes in the plate. At the same time, the punch trimming template trims the edges. The debris generated by punching falls into the hollow pad through the waste receiving interface. A blower blows air into the hollow pad, blowing the waste out from the waste discharge port. During punching, the ejector plate contacts the plate first, and the telescopic rod shortens to compress the ejector spring. After punching and trimming, the plate is now fitted onto the punching pin. The fixed pin plate and the punching pin move upward. At this time, the ejector spring extends and pushes the ejector plate downward relative to the fixed pin plate, removing the plate from the bottom of the punching pin. The sliding sleeve in the top plate springback reset mechanism cooperates with the guide post to make the punching and trimming actuator move up and down. When the external power mechanism resets, the compressed spring pushes the punching and trimming actuator upward quickly to reset through the sliding sleeve.

[0003] The patent document states that each punching and trimming operation requires the tedious process of placing the material to be punched into the mold. This process is tedious and monotonous. In addition, the interaction between the punching parts and the mold during the punching process can easily lead to the accumulation of heat. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-5 As shown, an elevator hanging plate punching and trimming mold includes an upper fixed plate 1, a mold assembly 2 is arranged below the upper fixed plate 1, a lower fixed plate 4 is arranged below the mold assembly 2, and a feeding mechanism 3 is also included, which is located on one side of the mold assembly 2.

[0029] In this embodiment: the feeding mechanism 3 includes a base 305, which is fixedly connected to one side of the top of the lower fixed plate 4. An upper clamping plate 303 is slidably connected inside the base 305. An oil trough 304 is fixedly connected to one side of the upper clamping plate 303. Multiple oil leakage holes are opened at the bottom of the oil trough 304. A brush is attached below the oil leakage holes of the oil trough 304. A lower clamping plate 302 is provided below the upper clamping plate 303. The side of the lower clamping plate 302 near the oil trough 304 is rotatably connected to the upper clamping plate 303. A first rubber block is fixed to the top of the other side of the lower clamping plate 302. A second rubber block corresponding to the rubber block of the lower clamping plate 302 is fixed to the bottom of the upper clamping plate 303. A connecting rod 301 is hinged to the lower clamping plate 302. The connecting rod 301 moves downward, causing the lower clamping plate 302 to rotate downward around the rotatable connection point with the upper clamping plate 303. The downward rotation of the lower clamping plate 302 causes the lower clamping plate 302 to rotate downward. The rubber block on 02 does not contact the material. The connecting rod 301 continues to move downward, causing the lower clamping plate 302 to move behind the material. The movement of the lower clamping plate 302 drives the upper clamping plate 303 and the oil tank 304 to move backward on the base 305. At the same time, the cooling oil in the oil tank 304 is brushed onto the material through the oil leakage hole at the bottom of the oil tank 304 and the brush at the bottom of the oil tank 304. The connecting rod 301 moves upward, causing the lower clamping plate 302 to rotate upward around the rotating connection with the upper clamping plate 303. The upward rotation of the lower clamping plate 302 causes the first rubber block on the lower clamping plate 302 and the second rubber block on the upper clamping plate 303 to clamp the material. After the lower clamping plate 302 clamps the material through the upper clamping plate 303, the lower clamping plate 302 stops rotating. The connecting rod 301 continues to move upward, causing the lower clamping plate 302 and the upper clamping plate 303 to clamp the material and move forward on the base 305.

[0030] In this embodiment: the mold assembly 2 includes a lower mold 207. The bottom of the lower mold 207 is fixedly connected to the other side of the top of the lower fixing plate 4. Two discharge holes are horizontally arranged in the middle of the lower mold 207. Discharge grooves are opened on the front and rear sides of the discharge holes of the two lower mold 207. A stop block 205 corresponding to the two discharge grooves is vertically fixed on the side of the lower mold 207 away from the base 305. Positioning rods 206 are vertically fixedly connected to the four corners of the top of the lower mold 207. The four positioning rods 206 slide upwards. The upper mold 201 is dynamically connected, and its top is fixedly connected to the bottom of the upper fixed plate 1. The upper end of the connecting rod 301 is hinged to the front side of the upper mold 201. A cutting blade 202 is fixedly connected to the side of the upper mold 201 away from the connecting rod 301. Two punches corresponding to the discharge holes are fixed at the bottom of the upper mold 201. Both sides of the two punches are provided with cutting blades corresponding to the discharge grooves of the two lower molds 207. A pressure plate 204 is provided inside the cutting blades of the two upper molds 201. The pressure plate 204 is provided with... The pressure plate 204 has through holes corresponding to the punches of the two upper dies 201. Each of the four corners of the top of the pressure plate 204 is vertically fixed with a sliding rod 203. Each of the four sliding rods 203 is fitted with a spring. The four sliding rods 203 are slidably connected to the upper dies 201. When the upper dies 201 move downwards, the pressure plate 204 contacts the material. After contact with the material, the pressure plate 204 stops moving, and the upper dies 201 slides on the four sliding rods 203, continuing to move downwards and compressing the four springs. The compression of the four springs produces… The spring force will exert pressure on the pressure plate 204. The pressure of the spring will cause the pressure plate 204 to press the material tightly. The upper mold 201 continues to move downward and punches and trims the material through the two punches and two trimming blades of the upper mold 201. The waste generated by punching and trimming is discharged out of the mold through the discharge hole and discharge groove of the lower mold 207. While the upper mold 201 starts a new round of punching and trimming, it will cut the material that has been punched and trimmed in the previous round through the cutting blade 202.

[0031] Working principle: During operation, the operator fixes the upper fixed plate 1 together with the upper die 201 to the stamping end of the punch press, and fixes the lower fixed plate 4 together with the lower die 207 and the feeding mechanism 3 to the fixed end of the punch press. It is necessary to ensure that the upper die 201 can slide freely up and down on the four positioning rods 206, and that the two punches of the two upper dies 201 can be inserted into the discharge holes of the two lower dies 207, and that the cutting blades of the two upper dies 201 can be inserted into the discharge slots of the two lower dies 207. Then, the material passes between the upper clamping plate 303 and the lower clamping plate 302 and is pushed against the two stops 205. As the material passes between the upper clamping plate 303 and the lower clamping plate 302, the cooling oil in the oil tank 304 is applied to the material through the oil leakage hole and a brush. The operator starts the press, which moves the upper die 201 downwards along the four positioning rods 206. This downward movement of the upper die 201, via the connecting rod 301, causes the lower clamping plate 302 to rotate downwards around its rotating connection with the upper clamping plate 303. This downward rotation of the lower clamping plate 302 causes the first rubber block of the lower clamping plate 302 and the second rubber block of the upper clamping plate 303 to move away from each other. As the upper die 201 continues to move downwards, the lower clamping plate 302 rotates to its limit position. After reaching this limit position, the downward movement of the upper die 201, via the connecting rod 301, causes the lower clamping plate 302 to move backwards from the material. This backward movement of the lower clamping plate 302 causes the upper clamping plate 303 and the oil tank 304 to move backwards on the base 305. Simultaneously, the cooling oil in the oil tank 304 flows from... The oil drain hole at the bottom of the oil tank 304 is used to brush the surface of the material passing through it with cooling oil via a brush at the bottom of the oil tank 304. The upper mold 201 moves downward so that the pressure plate 204 contacts the material. After the pressure plate 204 contacts the material, it stops moving. The upper mold 201 continues to move downward and compresses the four springs. The elastic force generated by the compression of the four springs will exert pressure on the pressure plate 204 to press the material. The upper mold 201 continues to move downward and punches and trims the material through the two punches and two trimming blades of the upper mold 201. The waste generated by punching and trimming is discharged from the mold through the discharge hole and discharge groove of the lower mold 207. When the upper mold 201 completes punching and trimming and begins to move upward, the upper mold 201... 1. The lower clamping plate 302 rotates upward around its rotational connection with the upper clamping plate 303 via the connecting rod 301. This upward rotation causes the first rubber block on the lower clamping plate 302 and the second rubber block on the upper clamping plate 303 to clamp the material. Once the material is clamped, the lower clamping plate 302 stops rotating, and the upper mold 201 continues to move upward, causing the material clamped by the lower clamping plate 302 and upper clamping plate 303 to move forward on the base 305. This forward movement causes the already punched and trimmed portion of the material to pass between the two stops 205, while the un-punched and trimmed portion is pushed against the two stops 205. The upper mold 201 then begins a new round of punching and trimming. During this punching and trimming process, the cutting blade 202 cuts off the material that was punched and trimmed in the previous round.In this way, the stamping machine can automatically feed materials and continuously complete the punching and trimming work.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
