Description

Technical Field

[0001] The utility model relates to the technical field of continuous die processing, in particular to a device for preventing waste from being pressed in continuous die processing. Background Art

[0002] A continuous die refers to a cold stamping die in which a press machine uses strip-shaped stamping raw materials to complete multiple stamping processes simultaneously on a die using several different workstations in one stamping stroke. Each time the die completes a stamping operation, the material strip moves a fixed distance until the product is completed.

[0003] With the update of technology, when processing through continuous dies, the base continuous die requires a large-tonnage press. In the stamping production process, the overall thickness of the product is reduced to a few millimeters due to stamping. When the punching is completed, the product relies on the feeder to drive the carrier to align and push in the mold, which is easy to cause difficulty in pushing out.

[0004] At the same time, due to the thin thickness of the product, it is easy to stick to the upper surface of the base due to stamping, and it is difficult to discharge the material only by blowing. It is impossible to unload the material quickly, resulting in the accumulation and covering of the finished products. As the stamping proceeds, it is easy to cause the finished products to be squeezed and deformed, resulting in scrapping. Therefore, the present application provides a device for preventing waste from being pressed in continuous die processing to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a device for preventing waste from being pressed in continuous die processing so as to solve the problem that, due to the thin thickness of the existing product, it is easy to stick to the upper surface of the base due to stamping, it is difficult to discharge the material only by blowing, and the finished products cannot be discharged quickly, resulting in accumulation and covering of the finished products.

DETAILED DESCRIPTION

[0025] The following is a detailed description of a device for preventing waste from being pressed in continuous die processing provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art may also adopt other alternative methods to implement them; and the accompanying drawings are only for describing the embodiments in more detail, and are not intended to specifically limit the utility model.

[0026] like Figure 1 - Figure 3 As shown, an embodiment of the utility model provides a device for preventing waste from being compressed in continuous mold processing, including a mold processing base 1, and a through groove 2 is opened at a rear section near the end shear point. It is easy to understand that the opening position of the through groove 2 is relative to the finished product section of the continuous mold processing part, and is relatively located on the side of the center point of the finished product close to the shear point, that is, relatively far away from the discharge port; a mounting seat 5 is fixedly connected to the bottom of the mold processing base 1 through a connecting rod 6, preferably four connecting rods 6 are provided, and are distributed in a rectangular array at the four corners of the mounting seat 5, and are located below the through groove 2; a push rod 3 is movably connected to the mounting seat 5, and is configured to be ejected from the bottom of the through groove 2 during demolding, and protrude from the mold processing base 1.

[0027] By setting the push rod 3 to push upward from the position of the through groove 2, the finished product is quickly pushed away from the side of the discharge port, so that the finished product can quickly separate from the mold processing base 1, and the separation direction is toward the side of the discharge port, thereby avoiding the finished product being stranded on the mold processing base 1, resulting in the problem of subsequent feeding causing the finished products to overlap and cover each other, and being squeezed and scrapped.

[0028] like Figure 2As shown, it also includes a positioning plate 9, two of which are provided and fixedly connected in parallel to each other between the mold processing base 1 and the mounting seat 5, and two pulleys 11 are rotatably connected in an upper and lower distribution between the two positioning plates 9, and the two pulleys 11 are connected by a synchronous ruler belt 10.

[0029] It can be understood that the rotation axes of the two synchronous scale belts 10 rotatably connected between the two parallel positioning plates 9 are perpendicular to each other, and because the two synchronous scale belts 10 are distributed up and down, it can be known that the synchronous scale belt 10 connected between the two pulleys 11 performs vertical circulation motion, and the two sides of the motion trajectory are vertical.

[0030] like Figure 1 As shown, it also includes: a motor 8, the output end of which is connected to the pulley 11 below; a base 7, located on the top of the mounting base 5, for fixing the motor 8 and raising the installation height of the motor 8.

[0031] The connecting rod 6 is provided to drive the pulley 11 to rotate, thereby realizing the movement of the synchronous ruler belt 10. Furthermore, the motor 8 adopts a stepping motor 8. By setting the rotation speed of the motor 8 and coordinating the stamping frequency of the continuous die processing production line, it is possible to assist in pushing the finished product out of the die processing base 1 each time.

[0032] like Figure 1 As shown, the top of the mounting seat 5 is vertically fixedly connected with a positioning rod 12, the positioning rod 12 is located directly below the through slot 2, and a spring 13 is sleeved on the rod body of the positioning rod 12; a sliding groove is provided inside the push rod 3 to cooperate with the sliding connection of the positioning rod 12, thereby ensuring that the push rod 3 moves up and down along the vertical direction; a limiting plate 4 is provided at the bottom of the push rod 3, the vertical projection area of ​​the limiting plate 4 is larger than the vertical projection area of ​​the push rod 3, and the upper and lower ends of the spring 13 are in close contact with the limiting plate 4 and the mounting seat 5 respectively.

[0033] The spring 13 provides elastic force to assist the push rod 3 to push up. When the spring 13 is under great pressure, its rebound force is also great, thereby driving the push rod 3 to move up and reset quickly, providing greater impact force to the processed finished product. At the same time, a buffer pad is provided on the top of the push rod 3 to avoid excessive rigid collision with the finished product, which may cause its deformation. Furthermore, when the motor 8 fails, the push rod 3 may be in a position protruding from the top of the through slot 2. At this time, when the continuous die processing is normally performing stamping work, since the bottom of the push rod 3 is supported by the spring 13, as the upper mold is pressed down, the push rod 3 can be synchronously lowered, and will not cooperate with the downward pressure of the upper mold to cause stamping deformation to the finished product.

[0034] like Figure 3 As shown, a wedge block 14 is provided on the outer side of the synchronous ruler tape 10 , and the wedge block 14 protrudes from the outer side wall of the synchronous ruler tape 10 .

[0035] The wedge blocks 14 are preferably set as two pieces, and are distributed symmetrically on the synchronous scale belt 10. When set as a single piece, the synchronous scale belt 10 needs to rotate one circle each time the limit plate 4 is pressed down, which consumes relatively large energy. When a large number of wedge blocks 14 are set, the limit plate 4 is easily blocked by the wedge block 14 located above during the upward rebound process, resulting in a decrease in the height of the push rod 3 protruding from the through slot 2, and the auxiliary pushing effect is not ideal.

[0036] like Figure 3 As shown, when the synchronous ruler 10 is configured to be transmitted, the movement direction of the side close to the limit plate 4 is from top to bottom, and there is a gap between the movement route of the synchronous ruler 10 and the side wall of the limit plate 4; the distance that the wedge block 14 protrudes from the outer side wall of the synchronous ruler 10 is greater than the distance between the movement route of the synchronous ruler 10 and the side wall of the limit plate 4; when the wedge block 14 is configured to follow the synchronous ruler 10 to move to the side close to the limit plate 4, the wedge block 14 contacts the top of the limit plate 4 and drives the limit plate 4 to move downward.

[0037] With this arrangement, when the pulley 11 drives the wedge block 14 to move to the side close to the push rod 3, the wedge block 14 can block the limit plate 4 and compress the spring 13 to complete the energy storage for the impact reset of the push rod 3.

[0038] In a further embodiment, there are preferably multiple through grooves 2 and ejector rods 3, wherein two through grooves 2 are opened parallel to each other, and the line connecting the two is perpendicular to the moving line of the production line, and the lower ends of the two ejector rods 3 are fixedly connected by the same limit plate 4 to ensure the synchronization of their ascent. Through this arrangement, when the finished product is impacted and lifted, the force is linear, ensuring that the direction of movement is always toward the position close to the discharge port when it is lifted, which is easier to control than the movement direction of a single ejector rod 3 with a single-point impact.

[0039] The technical solution provided by the utility model adjusts the speed of the motor 8 to cooperate with the continuous die processing production line, drives the pulley 11 to rotate through the motor 8, and then drives the synchronous ruler belt 10 to circulate. When the wedge block 14 moves to the side close to the top rod 3, it cooperates with the top of the limit plate 4 and drives the limit plate 4 and the top rod 3 to move downward as a whole. At this time, the spring 13 is compressed to complete the energy storage. As the wedge block 14 moves to the position close to the pulley 11 below and enters the curved section of the movement trajectory of the synchronous ruler belt 10, the wedge block 14 is separated from the crimping of the limit plate 4. At this time, the cutting parts on the continuous die processing production line have just completed the hedging. The extruded finished product is cut, and the limit plate 4 and the push rod 3 move upward quickly under the elastic force of the spring 13, and protrude from the through slot 2 to collide with the bottom of the cut finished product, so that it is separated from the mold processing base 1, and the blowing part cooperates to make the finished product completely separate from the mold processing base 1. It should be noted that when the push rod 3 rises, the limit plate 4 at its bottom contacts and limits the bottom of the mold processing base 1, so that the height of the push rod 3 protruding from the upper surface of the mold processing base 1 is relatively low, and the top of the push rod 3 is a spherical end face. Even if the motor 8 fails and the push rod 3 cannot automatically descend, it will not cause any obstruction to the feeding of materials on the production line, thereby further improving the practicality of the device.

[0040] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
