[0002] The annular zinc oxide resistor processing and forming equipment is a special equipment specially used for producing annular zinc oxide resistors. Through precise mold design and pressing technology, the equipment can press the material mixed with zinc oxide powder and organic binder into annular resistors with specific shapes and sizes. The formed resistors are pushed out of the pressing area by the pushing mechanism, so as to facilitate the subsequent pressing and forming of the resistors. However, when the existing pushing mechanism pushes the pressed resistors out of the pressing area, it basically pushes the resistors through a push plate, so that the resistors collide with each other, which easily causes the resistors to be damaged, resulting in an increase in the defective rate of the resistors. In addition, the push plate pushes the resistors, which will also cause the neatly arranged resistors to become chaotic, making the subsequent processing of the resistors inconvenient.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1

[0036] Reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, and provides a ring-shaped zinc oxide resistor processing and molding equipment. The ring-shaped zinc oxide resistor processing and molding equipment includes a main component 100, including a press 101, an upper mold 102 and a resistor 103. The upper mold 102 is arranged in the press 101, and the resistor 103 is located on the top of the press 101 table.

[0037] The main body component 100 is the prior art, and the press 101 drives the upper mold 102 to move downward, so that the upper mold 102 and the lower mold in the press 101 cooperate, thereby pressing and forming the resistor 103. At this time, the press 101 drives the upper mold 102 to move upward for resetting. At this time, the press 101 drives the lower mold to push out the resistor 103, so that the resistor 103 is located on the top of the press 101 table. The working principle of the above press 101 is the prior art and will not be repeated here.

[0038] The blanking assembly 200 is arranged on the press 101, and includes a blanking rod 201a sliding on the top of the press 101 table, an adjusting rod 201b sliding inside the blanking rod 201a, a driving column 201c fixed on the top of the adjusting rod 201b, a support rod 201d rotatably connected to the surface of the driving column 201c, a connecting block 201e hinged at the end of the support rod 201d, a push block 201f fixed on one side of the connecting block 201e, and a rotating Rod 201g, a fixed block 201h is hinged at the end of the rotating rod 201g, the fixed block 201h is fixed to one side of the unloading rod 201a, a placement groove 201a-1 is opened on one side of the unloading rod 201a, and the push block 201f can be received in the placement groove 201a-1, and a driving block 201i is fixed on the top of the adjusting rod 201b, and a first spring 201j is fixed on one side of the driving block 201i, and the other end of the first spring 201j is fixed to the inner wall of the unloading rod 201a.

[0039] The first spring 201j is in a stretched state. When the adjusting rod 201b slides in the unloading rod 201a and stretches the first spring 201j, the adjusting rod 201b can drive the supporting rod 201d to move through the driving column 201c, so that the supporting rod 201d drives the pushing block 201f to move through the connecting block 201e, so that the pushing block 201f moves out of the placement groove 201a-1, and is supported by the rotating rod 201g and the fixed block 201h, so that the pushing block 201f moves to the side of the resistor 103 according to the predetermined moving trajectory. At this time, the unloading rod 201a is moved, and the resistor 103 can be pushed out of the pressing area under the joint action of the two pushing blocks 201f on one side of the resistor 103, and the formation of the resistor 103 can be kept neat.

[0040] When the thrust on the adjusting rod 201b is reduced, under the action of the reset tension of the first spring 201j, the driving block 201i can drive the adjusting rod 201b to move in the opposite direction in the unloading rod 201a, so that the adjusting rod 201b drives the pushing block 201f to move closer to the unloading rod 201a through the driving column 201c and the supporting rod 201d, thereby storing the pushing block 201f in the placement groove 201a-1. At this time, the rotating rod 201g is in a parallel state with the unloading rod 201a, so that when the unloading rod 201a is reset, the rotating rod 201g and the pushing block 201f will not hit the resistor 103 that has been pushed out of the pressing area, ensuring that the formation of the resistor 103 will not be disordered when the unloading rod 201a is reset.

[0041] Example 2

[0042] Reference Figure 7 to Figure 12 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0043] Specifically, the material removal assembly 200 also includes a driving member 202, which is arranged on the surface of the material removal rod 201a, including a movable shell 202a sliding on the surface of the material removal rod 201a, and a push plate 202b slides in the movable shell 202a, and the push plate 202b is fixed to the top of the material removal rod 201a.

[0044] A plurality of discharge rods 201a are fixed at the bottom of the push plate 202b. By moving the push plate 202b in the movable shell 202a, the plurality of discharge rods 201a can be extended out or retracted into the movable shell 202a at the same time. In the current state, the push plate 202b moves to the end of the inner wall of the movable shell 202a. At this time, the push plate 202b cannot continue to drive the plurality of discharge rods 201a to extend out of the movable shell 202a. At this time, if the movable shell 202a moves, the plurality of discharge rods 201a can be driven to move synchronously, so that the plurality of discharge rods 201a push the neatly arranged resistor sheets 103 out of the pressing area.

[0045] Specifically, a guide shell 202c is fixed in the movable shell 202a, a fixed tube 202d is fixed in the guide shell 202c, an air pipe 202e is fixed in the fixed tube 202d, a first telescopic bag 202f is fixed on one side of the fixed tube 202d, a sliding tube 202g is fixed on the other end of the first telescopic bag 202f, and the sliding tube 202g is fixed to one side of the push plate 202b.

[0046] The semi-enclosed structure of the guide shell 202c is used to guide the moving direction of the first telescopic bag 202f, so that the first telescopic bag 202f will not move out of the guide shell 202c during the telescopic movement. When the air pressure in the first telescopic bag 202f increases, the first telescopic bag 202f will be extended, and when the air pressure in the first telescopic bag 202f decreases, the first telescopic bag 202f will be contracted. The guide shell 202c fixes the fixed tube 202d, so that the first telescopic bag 202f drives the sliding tube 202g to slide in the guide shell 202c during the telescopic process, so that the sliding tube 202g can drive the push plate 202b to move synchronously. The gas supply pipe 202e is used to input high-pressure gas into the fixed tube 202d, or to extract the high-pressure gas in the fixed tube 202d, so that negative pressure is formed in the fixed tube 202d. This method of high-pressure gas input or extraction is a prior art, and those skilled in the art should be clearly aware of it and will not be elaborated here.

[0047] Furthermore, a sleeve 202h is slidably connected inside the push plate 202b, a second spring 202i is sleeved on the surface of the sleeve 202h, two ends of the second spring 202i are respectively fixed to one side of the sleeve 202h and the inner wall of the push plate 202b, a limiting strip 202j is fixed to the surface of the sleeve 202h, a push rod 202k is provided on one side of the sleeve 202h, and the push rod 202k is fixed to the inner wall of the movable shell 202a.

[0048] The second spring 202i is in a compressed state, and is used to push the sleeve 202h. In the current state, the first telescopic bag 202f is extended by high-pressure gas, so that the sliding tube 202g drives the push plate 202b to move. In this process, multiple unloading rods 201a are moved between neatly arranged resistor sheets 103. When the push plate 202b moves to the inner wall of the moving shell 202a, the push rod 202k can squeeze the sleeve 202h, so that the sleeve 202h further compresses the second spring 202i. By setting the limit strip 202j, the sleeve 202h will not rotate relative to the push plate 202b during the movement.

[0049] Among them, a flow channel 202b-1 is opened in the push plate 202b, and a through hole 202h-1 is opened on the surface of the sliding sleeve 202h, and the flow channel 202b-1 can be connected with the through hole 202h-1. In the current state, the sliding sleeve 202h is squeezed by the push rod 202k, so that the flow channel 202b-1 opened in the push plate 202b and the through hole 202h-1 opened on the surface of the sliding sleeve 202h are connected, so that the high-pressure gas in the sliding tube 202g can enter the flow channel 202b-1 through this connection.

[0050] An air guide hole 201a-2 is provided at the top of the discharge rod 201a, and the air guide hole 201a-2 can be connected to the flow channel 202b-1. A piston 2021 is fixed to the end of the adjustment rod 201b, and the piston 2021 slides in the discharge rod 201a.

[0051] During use, when high-pressure gas is filled into the flow channel 202b-1, the high-pressure gas can enter the discharge rod 201a through the gas guide hole 201a-2, thereby pushing the piston 202l, so that the piston 202l drives the adjusting rod 201b to move relative to the discharge rod 201a, thereby compressing the first spring 201j, so that the push block 201f extends out of the placement slot 201a-1 and moves to the side of the resistor 103.

[0052] Embodiment 3,

[0053] Reference Figure 13-14 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0054] Specifically, the blanking assembly 200 further includes a support member 203, which is disposed on the press 101 and includes a support platform 203a fixed on the press 101, a support block 203b is fixed on the top of the support platform 203a, a support shell 203c is fixed on one side of the support block 203b, a support frame 203d is fixed on the top of the support shell 203c, and the support frame 203d is fixed on the top of the support platform 203a. The support platform 203a is used to support the movable shell 202a, and the support block 203b and the support frame 203d cooperate to fix and support the two support shells 203c.

[0055] Furthermore, the unloading assembly 200 also includes a unloading part 204, which is arranged in the supporting shell 203c, including an air duct 204a fixed in the movable shell 202a, and an air supply hole 201a-3 is opened on the top of the unloading rod 201a, and the air supply hole 201a-3 can be connected to the air duct 204a.

[0056] When the push block 201f extends out of the placement groove 201a-1 and moves to the side of the resistor 103, the movement of the piston 202l just connects the gas hole 201a-3 with the cavity in the discharge rod 201a, so that the high-pressure gas in the discharge rod 201a can be transported to the air guide pipe 204a through the gas hole 201a-3.

[0057] Among them, a support tube 204b is fixed in the support shell 203c, a second telescopic bag 204c is fixed to one side of the support tube 204b, a movable tube 204d is fixed to the other end of the second telescopic bag 204c, a third spring 204e is fixed to one side of the movable tube 204d, and the other end of the third spring 204e is fixed to the inner wall of the support shell 203c.

[0058] One end of the air guide tube 204a is connected to the air delivery hole 201a-3, and the other end is inserted into the movable tube 204d. The air guide tube 204a can deliver high-pressure gas to the movable tube 204d, so that the second telescopic bag 204c on one side of the movable tube 204d is extended under the push of the high-pressure gas. Since the support tube 204b is fixed in the support shell 203c, the second telescopic bag 204c pushes the movable tube 204d to move in the support shell 203c, so that the movable tube 204d compresses the third spring 204e.

[0059] A pressure relief hole is provided at the end of the support tube 204b. When high-pressure gas is no longer input into the movable tube 204d, the high-pressure gas in the second bellows 204c is discharged through the pressure relief hole at the end of the support tube 204b, thereby causing the second bellows 204c to contract.

[0060] A guide bar 104 is fixed on the top of the press 101 table, and the movable shell 202a is located between two guide bars 104. Through the limitation of the two guide bars 104, the movable shell 202a is allowed to move stably, so that no deviation occurs.

[0061] This embodiment also provides a method for using the annular zinc oxide resistor processing and forming device, the method is as follows:

[0062] When in use, when it is necessary to push the pressed resistor sheet 103 out of the pressing area, firstly, high-pressure air is input into the air pipe 202e, so that the air pipe 202e transmits the high-pressure air to the fixed pipe 202d, so that the air pressure in the first telescopic bag 202f increases, and the first telescopic bag 202f stretches, so that the sliding pipe 202g drives the push plate 202b to move. In this process, the multiple unloading rods 201a move between the neatly arranged resistor sheets 103. When the push plate 202b moves to the inner wall of the movable shell 202a, The push rod 202k squeezes the sleeve 202h, so that the sleeve 202h further compresses the second spring 202i, so that the flow channel 202b-1 opened in the push plate 202b is connected with the through hole 202h-1 opened on the surface of the sleeve 202h, so that the high-pressure gas in the sliding tube 202g can enter the flow channel 202b-1 through this connection. When the flow channel 202b-1 is filled with high-pressure gas, the high-pressure gas can enter the discharge rod 201a through the gas guide hole 201a-2, thereby pushing the piston 202l. The piston 2021 moves, so that the adjusting rod 201b moves relative to the feeding rod 201a, thereby compressing the first spring 201j, so that the push block 201f extends out of the placement groove 201a-1 and moves to the side of the resistor 103. At this time, the movement of the piston 2021 just makes the gas delivery hole 201a-3 and the cavity in the feeding rod 201a communicate with each other, so that the high-pressure gas in the feeding rod 201a can be delivered to the gas guide pipe 204a through the gas delivery hole 201a-3, and the gas guide pipe 204a can deliver the high-pressure gas to the movable pipe 204d. , so that the second telescopic bag 204c on one side of the movable tube 204d is extended under the push of the high-pressure gas. Since the support tube 204b is fixed in the support shell 203c, the second telescopic bag 204c pushes the movable tube 204d to move in the support shell 203c, so that the movable tube 204d compresses the third spring 204e, so that the movable shell 202a moves on the top of the support platform 203a, so that the movable shell 202a drives multiple unloading rods 201a to push the neatly arranged resistor sheets 103 out of the pressing area.After the resistor 103 is pushed out of the pressing area, the fixed tube 202d is evacuated through the air pipe 202e, so that the air pressure in the fixed tube 202d begins to drop. At this time, under the reset tension of the first spring 201j, the driving block 201i can drive the adjusting rod 201b to move in the reverse direction in the lower material rod 201a, so that the adjusting rod 201b drives the push block 201f to move closer to the lower material rod 201a through the driving column 201c and the support rod 201d, so that the push block 201f is stored in the placement groove 201a-1. At this time, the rotating rod 201g is in a parallel state with the unloading rod 201a, so that when the unloading rod 201a is reset, the rotating rod 201g and the push block 201f will not hit the resistor 103 that has been pushed out of the pressing area, ensuring that when the unloading rod 201a is reset, the formation of the resistor 103 will not be disordered, and at this time, the reset movement of the piston 202l and the adjusting rod 201b will block the gas supply hole 201a-3, so that the gas supply hole 201a-3 is no longer connected to the cavity in the unloading rod 201a.

[0063] When the push block 201f is stored in the placement groove 201a-1, the high-pressure gas in the second telescopic bag 204c will be discharged through the pressure relief hole at the end of the support tube 204b through the elastic force of the third spring 204e, so that the second telescopic bag 204c will shrink, so that the movable shell 202a will reset and move under the push of the third spring 204e, thereby driving the unloading rod 201a away from the resistor 103.

[0064] At the same time, since the air supply pipe 202e evacuates the fixed pipe 202d, when the air pressure in the lower feeding rod 201a drops, the air pressure in the first telescopic bag 202f will drop synchronously, causing the first telescopic bag 202f to begin to shrink. At this time, the first telescopic bag 202f can drive the push plate 202b to slide in the movable shell 202a, so that the sliding sleeve 202h is away from the push rod 202k. At this time, under the action of the reset elastic force of the second spring 202i, the sliding sleeve 202h slides in the push plate 202b, so that the flow channel 202b-1 opened in the push plate 202b and the through hole 202h-1 opened on the surface of the sliding sleeve 202h are no longer connected. As the first telescopic bag 202f shrinks, the push plate 202b drives multiple lower feeding rods 201a to shrink into the movable shell 202a, thereby completing the reset of the movable shell 202a and the lower feeding rod 201a.
