Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pin processing equipment, in particular to a pin shearing machine. BACKGROUND

[0002] In the production process, the pins of small transformers may have excess length, and due to the actual installation, the small transformers are installed in a certain limited space, therefore, in order to facilitate the access of the pins, the too long pins need to be bent, and the bent and long pins may touch the joints of other circuits, causing circuit failure. Therefore, in the production and use process, cutting off the excess length of the pins of the small transformer is a common safety measure.

[0003] At present, the excess length of the pins is generally cut off by a pin shearing machine in the factory, but in the cutting process of the pin shearing machine, the cut-off pins will fall on the ground or the machine, or even the gap of the machine, not only causing trouble for the subsequent cleaning work, but also the pins are easy to fall into the connecting gap of each part of the pin shearing machine, which is easy to cause the jamming of each part of the pin shearing machine.

[0004] According to the related technology in the above, there is a defect that the excess length of the pins falls into the connecting gap of each part, which is easy to cause damage to the pin shearing machine. SUMMARY

[0005] In order to prevent the pins from falling into the connecting gap of each part as much as possible, thereby reducing the probability of damage to the pin shearing machine, the present application provides a pin shearing machine.

[0006] The pin shearing machine provided by the present application adopts the following technical scheme:

[0007] A pin shearing machine comprises:

[0008] a base;

[0009] a support seat installed on the base;

[0010] a mounting seat installed on the upper end face of the support seat, and a mounting hole for the pins to pass through is formed in the mounting seat;

[0011] two cutting knives, both of which are slidingly installed on the support seat, and the two cutting knives are used to cut off the pins between the two cutting knives;

[0012] a driving assembly installed on the base and connected with the cutting knives, and the driving assembly is used to drive the two cutting knives to move in the direction of approaching or moving away from each other;

[0013] A collecting box is placed on the base and is located below the mounting hole.

[0014] When the excess pins of the small transformer need to be cut, the small transformer is placed on the mounting base, the pins of the small transformer pass through the mounting hole and are located between the two cutting knives, then the driving assembly drives the two cutting knives to move in the direction of approaching each other until the cutting knives cut the excess pins of the small transformer, at this time, the cut pins will fall into the collecting box, thereby avoiding the cut pins falling on the ground or the machine, even the gap of the machine, and simplifying the subsequent cleaning work; the falling of the pins into the connecting gap of the components is prevented, thereby reducing the damage probability of the pin cutting machine; in addition, the traditional cutting method is single knife and single direction cutting, while the device is provided with two cutting knives and the two cutting knives cut towards each other, thereby greatly improving the cutting efficiency of the cutting knives.

[0015] Optionally, the diameter of the mounting hole is equal to the diameter of the pin.

[0016] Through the above technical scheme, in the production process of the small transformer, the pin of the small transformer may be bent due to collision, and cutting the excess pins of the small transformer will cause the actual length of the cut pins to be less than the required length, which may affect the subsequent installation of the small transformer; in the device, since the diameter of the mounting hole is equal to the diameter of the pin, the bent pin cannot pass through the mounting hole, and the pin of the small transformer can pass through the mounting hole and be cut only after the pin of the small transformer is corrected by the worker, thereby ensuring that the length of the cut pin of the small transformer is within the specified range, and improving the yield of the small transformer.

[0017] Optionally, the pin cutting machine further comprises a fixing mechanism, the fixing mechanism comprises a support frame and a pressing device, the support frame is installed on the support base and located above the mounting base, and the pressing device is installed on the support frame in the vertical direction, and the output shaft of the pressing device is opposite to the mounting hole.

[0018] By adopting the technical scheme, since the pins are connected to the transformer, when the cutting knives cut the excess pins of the small transformer, the small transformer will inevitably shake, which can easily cause the pins to slide out of the mounting holes by a distance, so that the cutting knives cannot cut the pins to the required length or the pins have more burrs, and in the device, when the small transformer is placed on the mounting seat and the pins are inserted into the mounting holes, the cylinder is started, the output shaft of the cylinder is lowered, an external force is applied to the small transformer, the small transformer is tightly pressed against the upper end surface of the mounting seat, the shaking of the small transformer is avoided as much as possible, and the cutting knives can cut the pins to the required length and improve the cutting effect.

[0019] Optionally, a guide assembly is arranged between the mounting seat and the collecting box, and the guide assembly comprises a guide block and a reset member.

[0020] The guide block is located below the mounting hole and between the two cutting knives, an inclined groove is formed in the end surface of the guide block close to the mounting hole, the inclined groove extends to one side of the guide block, the two sides of the guide block are respectively in sliding abutment with the two cutting knives, and the end surfaces of the guide block and the cutting knives in abutment are inclined surfaces.

[0021] The reset member is located between the base and the guide block, and the reset member is used to drive the guide block to return to the original position after being pressed and lowered.

[0022] By adopting the technical scheme, since the pins are connected to the transformer, when the cutting knives cut the excess pins of the small transformer, the small transformer will inevitably shake, which can easily cause the pins to slide out of the mounting holes by a distance, so that the cutting knives cannot cut the pins to the required length or the pins have more burrs, and in the device, when the small transformer is placed on the mounting seat and the pins are inserted into the mounting holes, the cylinder is started, the output shaft of the cylinder is lowered, an external force is applied to the small transformer, the small transformer is tightly pressed against the upper end surface of the mounting seat, the shaking of the small transformer is avoided as much as possible, and the cutting knives can cut the pins to the required length and improve the cutting effect.

[0023] Optionally, the support seat is provided with a half-enclosing plate on both sides in the arrangement direction of the chute.

[0024] By adopting the above technical scheme, when the cutting knife cuts off the pin, the cut-off pin may hit the guide block and rebound to other parts of the pin cutting machine or the body of the worker due to the certain shearing stress of the cutting knife on the pin, which may cause damage to the body of the pin cutting machine or the human body. Therefore, by arranging the half-enclosing plate, the cut-off pin can be prevented from rebounding to other parts of the machine body or the human body as much as possible, thereby further reducing the probability of damage to the pin cutting machine and reducing the safety hazard.

[0025] Optionally, the upper end faces of the two cutting knives are in sliding abutment with the lower end face of the mounting seat, and the mounting seat, the cutting knives and the guide block jointly enclose the space on both sides of the pin.

[0026] By adopting the above technical scheme, since the space on both sides of the pin is enclosed, when the pin is cut off, the pin goes out from the space on both sides, thereby compressing the activity space of the cut-off pin and increasing the probability of falling into the collection box.

[0027] Optionally, one side of each of the two cutting knives is provided with a stop block, the two stop blocks are in abutment with each other when the two cutting knives are close to each other, and the stop blocks are in sliding abutment with the end faces of the guide block away from the chute.

[0028] By adopting the above technical scheme, since the stop blocks are arranged on the cutting knives and the stop blocks are in sliding abutment with the end faces of the guide block away from the chute, the cutting knives, the stop blocks and the guide block jointly enclose the space on the other side of the pin, thereby further compressing the activity space of the cut-off pin and further increasing the probability of falling into the collection box.

[0029] Optionally, the opposite end faces of the two stop blocks are provided with elastic blocks, and the distance between the two elastic blocks is shorter than the distance between the two cutting knives.

[0030] By adopting the above technical scheme, when the two cutting knives move in the direction of approaching each other, the cutting edges of the cutting knives may collide to some extent, which is easy to cause damage to the cutting knives. Therefore, by arranging the elastic blocks, the two cutting knives can have a certain buffer between the collisions, thereby reducing the impact force between the two cutting knives and further reducing the probability of damage to the cutting knives.

[0031] Optionally, one end of the collection box is provided with a baffle, the baffle faces the chute on the guide block, the collection box is provided with side plates on both sides in the width direction, and the two side plates are arranged opposite to each other and connected with the baffle.

[0032] By adopting the technical scheme, since the cutting knife generates a certain shearing stress on the pin, the pin may be pushed onto the inclined surface of the chute by the shearing stress when being cut off, and then rebound onto other components of the pin cutting machine or other human bodies, therefore, the pins rebounding from the chute are blocked by the baffle and the side plate, and thus fall into the collecting box, so that the probability of falling into the collecting box is further improved as a whole.

[0033] Optionally, the two side plates are arranged in a direction away from each other.

[0034] By adopting the technical scheme, the range of the pins intercepted by the two side plates and the baffle is increased, so that the probability of falling into the collecting box is further improved.

[0035] In summary, the present application has at least one of the following beneficial technical effects:

[0036] 1. The collecting box is arranged to collect the cut-off pins, so as to avoid the cut-off pins falling on the ground or the machine, or even into the gap of the machine, thereby simplifying the subsequent cleaning work as a whole, and preventing the pins from falling into the connecting gap of each component, thereby reducing the probability of damage of the pin cutting machine; in addition, two cutting knives are arranged in the device, and the two cutting knives cut towards each other, which greatly improves the cutting efficiency of the cutting knife.

[0037] 2. The close cooperation of the guide block, the cutting knife and the stop block blocks the space on three sides of the pin, so that the pin can only fall into the chute and then fall into the collecting box, thereby avoiding the pin rebounding onto other components of the pin cutting machine or the human body, and reducing the probability of damage of the pin cutting machine and the safety hazard as a whole.

[0038] 3. The arrangement of the half-enclosing plate, the baffle and the side plate compresses the space opposite to the chute, so that the probability of the pin flying out of the end surface of the chute is reduced, thereby further reducing the probability of damage of the pin cutting machine and the safety hazard.

[0039] 4. Since the diameter of the mounting hole is equal to that of the pin, the curved pin cannot pass through the mounting hole, and the pin of the small transformer can pass through the mounting hole and be cut off only when the staff corrects the pin of the small transformer, so as to ensure that the length of the cut-off pin of the small transformer is within the specified range as a whole, thereby improving the yield of the small transformer.

DETAILED DESCRIPTION

[0051] The following will be combined with the Figures 1-9 The present application is further explained.

[0052] Embodiment 1

[0053] The embodiment of the present application discloses a clipper. Referring to Figure 1 A clipper includes a base 1, a support seat 2, a mounting seat 3, a cutting knife 4, a collection box 5, a driving assembly 6 and a fixed mechanism 7.

[0054] The lower end surface of the base 1 is provided with a plurality of supporting blocks 11, preferably four in this embodiment, which are fixedly connected to the four corners of the lower end surface of the base 1.

[0055] The support seat 2 is installed on the upper end surface of the base 1, and the support seat 2 is a cuboid shelf as a whole, and each end surface is provided with an opening.

[0056] Referring to Figure 2 and Figure 3 , the mounting seat 3 is fixedly installed on the upper end surface of the support seat 2, and the mounting seat 3 is provided with mounting holes 31 for the pins to pass through. The number of mounting holes 31 can be set according to the actual situation. This device is mainly designed for small transformers 10, so the number of mounting holes 31 in this embodiment is set to four, and the arrangement of the four mounting holes 31 is also determined according to the layout of the pins of the small transformer 10. The mounting seat 3 is also provided with a support 32 specially used for placing the small transformer 10. The support 32 is also provided with through holes communicating with the mounting holes 31. The mounting holes 31 and the through holes are coaxial and have the same diameter.

[0057] Among them, the hole diameter of the mounting hole 31 can be greater than or equal to the diameter of the pin on the small transformer 10. When the hole diameter of the mounting hole 31 is greater than the diameter of the pin on the small transformer 10, it is convenient for the pin to be inserted into the mounting hole 31. When the hole diameter of the mounting hole 31 is equal to the diameter of the pin on the small transformer 10, it is convenient for the unqualified small transformer 10 to be distinguished.

[0058] Referring to Figure 3 and Figure 4 , the support seat 2 is provided with a sliding groove 22 for the cutting knife 4 to slide along the horizontal transverse direction, and the sliding groove 22 is located below the mounting seat 3. The cutting knife 4 is provided with two cutting knives 4, which are inserted from the two sides of the support seat 2. The two cutting knives 4 can slide in the direction of approaching or moving away from each other in the sliding groove 22. The cutting knife 4 simultaneously slides and abuts against the groove wall of the sliding groove 22 and the lower end surface of the mounting seat 3.

[0059] The cutting knife 4 is a cuboid as a whole. The opposite ends of the two cutting knives 4 are blade parts. The upper surfaces of the blade parts on the two cutting knives 4 abut against the mounting seat 3. The lower surfaces of the blade parts on the two cutting knives 4 are inclined surfaces inclined in the direction of moving away from each other. After the pin passes through the mounting hole 31, it is located between the blades of the two cutting knives 4.

[0060] Referring to Figure 1 , the driving assembly 6 is provided with two driving assemblies 6, which are located on the two sides of the support seat 2 and correspond to the two cutting knives 4 one by one. The driving assembly 6 includes a mounting plate 61, a supporting plate 62 and a driving cylinder 63.

[0061] The mounting plate 61 is arranged along the vertical direction and is fixedly installed on the upper end surface of the base 1. The driving cylinder 63 is installed on the side of the mounting plate 61 away from the support seat 2. The mounting plate 61 is provided with a through hole 611 through which the output shaft of the driving cylinder 63 passes. The cutting knife 4 is provided with a special-shaped nut 43 on the end close to the driving cylinder 63. The output shaft of the driving cylinder 63 is threadedly connected with the cutting knife 4 through the special-shaped nut 43, so that the cutting knife can be installed and dismounted.

[0062] In addition, the base 1 is further provided with two support plates 62. The two support plates 62 are triangular and are located on the two sides of the driving cylinder 63. A vertical side of the support plate 62 is fixedly connected with the mounting plate 61, so as to increase the stability of the mounting plate 61 and the stability of the driving cylinder 63 during work.

[0063] The fixing mechanism 7 comprises a support frame 71 and a pressing device 72.

[0064] The support frame 71 is fixedly installed on the upper end surface of the support seat 2 and is located above the mounting seat 3. The pressing device 72 in the embodiment is a cylinder. Of course, in other embodiments, the pressing device 72 can be a combination of a screw rod and a nut pair assembly and a motor, etc. The pressing device 72 is installed on the support frame 71 along the vertical direction, and the output shaft of the pressing device 72 is opposite to the mounting hole 31. In addition, the end surface of the pressing device 72 opposite to the mounting hole 31 is provided with a pressing block 73. Through the arrangement of the pressing device 72 and the pressing block 73, the small transformer 10 can be fixed well, so as to avoid shaking of the small transformer 10 and affect the cutting work of the pin. In addition, in order to avoid that the pressing block damages the small transformer 10, the pressing block 73 can be selected to have a certain elasticity.

[0065] Referring to Figure 3 and Figure 5 The collecting box 5 is a cuboid box and can also be a box with a storage function in other shapes. The collecting box 5 is placed on the upper end surface of the base 1 and is located below the mounting hole 31. The opening of the collecting box 5 is opposite to the mounting hole 31.

[0066] When the excess pins of the small transformer 10 need to be cut off, the small transformer 10 is placed on the support 32, and the pins of the small transformer 10 pass through the mounting hole 31 and are located between the two cutting knives 4, then the pressing block 73 is pressed against the upper end face of the small transformer 10 through the pressing device 72, then the switch 64 is opened, and the two cutting knives 4 are driven to move in the direction of approaching each other by the driving cylinder 63 until the cutting knives 4 cut off the excess pins of the small transformer 10, at which time the cut-off pins will fall into the collection box 5, thereby avoiding the situation that the cut-off pins fall on the ground or the machine or even the gap of the machine, and thus simplifying the subsequent cleaning work as a whole; and the pins are prevented from falling into the connecting gap of each component as much as possible, thereby reducing the probability of damage of the pin cutting machine; in addition, the traditional cutting method is mostly single-knife and single-direction cutting, while two cutting knives 4 are arranged in the device, and the two cutting knives 4 cut towards each other, which greatly improves the cutting efficiency of the cutting knives 4.

[0067] With reference to Figure 3 , a guide assembly 8 is arranged between the mounting seat 3 and the collection box 5, and the guide assembly 8 includes a guide block 81 and a reset member 82.

[0068] The guide block 81 is located below the mounting hole 31 and between the two cutting knives 4, and the end face of the guide block 81 close to the mounting hole 31 is provided with a inclined groove 811 close to the collection box 5 (see Figure 6 ), and the inclined groove 811 extends to one side of the guide block 81, and the two sides of the guide block 81 are respectively in sliding abutment with the two cutting knives 4, and the end faces of the guide block 81 and the cutting knives 4 are both inclined downward.

[0069] The reset member 82 is provided with four, and the four reset members 82 are located between the base 1 and the guide block 81, and the four reset members 82 are located at the four corners of the guide block 81, and the reset member 82 includes a guide column 821 and a reset spring 822.

[0070] The guide column 821 is provided with two, and the two guide columns 821 are coaxially arranged in the vertical direction, one of which is fixedly connected with the guide block 81, and the other is fixedly connected with the upper end face of the base 1, and the reset spring 822 is simultaneously sleeved on the two guide columns 821, one end of the reset spring 822 is fixedly connected with the lower end face of the guide block 81, and the other end of the reset spring 822 is fixedly connected with the upper end face of the base 1.

[0071] Since the pin is cut by the cutting knife 4, the cutting knife 4 will generate a radial shear stress on the pin, so that the cut pin moves a certain distance in the horizontal direction when falling, causing the cut pin to fall outside the collection box 5, and through the arrangement of the guide block 81, the cut pin can first fall into the inclined groove 811 of the guide block 81, and then slide along the inclined surface of the inclined groove 811 into the collection box 5, thereby further simplifying the subsequent cleaning work and reducing the probability of damage to the pin cutting machine.

[0072] In addition, since the sliding abutting surface of the guide block 81 and the cutting knife 4 is a downward inclined inclined surface, when the two cutting knives 4 move towards each other, the cutting knife 4 generates a downward thrust on the guide block 81 until the guide block 81 is completely located below the cutting knife 4, at this time the reset spring 822 is in a compressed state, after the cutting knife 4 completes the cutting of the pin, the driving cylinder 63 drives the two cutting knives 4 to move in a direction away from each other, and the reset spring 822 resets the guide block 81 to move upward to the original position, in this process, the cutting knife 4 and the guide block 81 are always in abutting state, and the guide block 81 does not affect the cutting work of the cutting knife 4, so as to further avoid the pin from falling into the connection gap of each component as a whole, thereby further reducing the probability of damage to the pin cutting machine.

[0073] Referring to Figure 3 and Figure 4 , one side of each of the two cutting knives 4 is provided with a stop block 41, and the two stop blocks 41 abut each other when the two cutting knives 4 approach, and the stop block 41 and the end surface of the guide block 81 away from the inclined groove 811 slide abut.

[0074] The opposite end surfaces of the two stop blocks 41 are each provided with an elastic block 42, and the distance between the two elastic blocks 42 is shorter than the distance between the two cutting knives 4, so that the two cutting knives 4 can abut each other during the approach, and the spring block reduces the impact force between the two cutting knives 4, thereby reducing the probability of damage to the cutting knife 4.

[0075] Referring to Figure 5 , one end of the collection box 5 is provided with a baffle 51, and the baffle 51 faces the inclined groove 811 on the guide block 81, and the collection box 5 is provided with a side plate 52 on both sides in the width direction, and the two side plates 52 are oppositely arranged and connected with the baffle 51. The two side plates 52 are inclinedly arranged in a direction away from each other.

[0076] Therefore, the space on both sides of the pin is always in a closed state.

[0077] In addition, when the two cutting knives 4 move in the direction of approaching each other to cut the pin, the stopper 41 on the two cutting knives 4 is also in the abutting state, and the stopper 41 is always in abutting state with the guide block 81. Therefore, the stopper 41, the cutting knife 4 and the guide block 81 jointly close the space on the other side of the pin.

[0078] Finally, the baffle 51 and the side plate 52 on the collection box 5 compress the space on the last side of the pin. Therefore, even if the pin pops out from the space on the last side, it will be intercepted by the baffle 51 and the side plate 52, and then falls into the collection box 5. Therefore, the cut pin is always guided to slide along the inclined groove 811 of the guide block 81 to the collection box 5, so as to further avoid the pin from falling into the connection gap of each component or rebounding to the human body, thereby further reducing the probability of damage and safety hazards of the pin cutting machine.

[0079] With reference to Figure 3 The support seat 2 is also provided with a half-enclosing plate 21 on both sides in the arrangement direction of the inclined groove 811, which also reduces the probability of pin ejection.

[0080] Embodiment 2

[0081] The difference between the embodiment of the present application and embodiment 1 is that:

[0082] With reference to Figure 7 And Figure 8 The cutting knife 4 is provided with a fixing piece 9, and the fixing piece 9 includes an abutting block 91 and a clamping block 92.

[0083] The abutting block 91 is fixedly connected to the lower end surface of the mounting seat 3, and the hole wall of the mounting hole 31 is in the same vertical plane as the side wall of the abutting block 91.

[0084] The clamping block 92 is provided with two clamping blocks 92 corresponding to the two cutting knives 4 respectively, and the two clamping blocks 92 are fixedly connected to the two cutting knives 4 respectively and arranged opposite to each other. The clamping block 92 is triangular, and the inclined surface of the clamping block 92 is connected to the inclined surface of the cutting edge of the cutting knife 4. The vertical side of the clamping block 92 is in the same vertical plane as the cutting edge of the cutting edge. The guide block 81 is also provided with a through groove 812 for the clamping block 92 to slide (with reference to Figure 9The through groove 812 is communicated with the inclined groove 811.

[0085] When the two cutting knives 4 move in the direction of approaching each other, the clamping block 92 moves in the direction of approaching the abutting block 91 until the pin is abutted on the side of the abutting block 91, and at the same time, the cutting edges of the cutting knives 4 begin to cut the excess pin.

[0086] Since the pin of the small transformer 10 is elastic, when the cutting knives 4 cut the pin, the pin may be bent, resulting in that the pin is not cut or the cut of the pin has burrs. Through the arrangement of the clamping block 92 and the abutting block 91, the end of the pin away from the small transformer 10 is fixed, so that the pin cannot be bent when being cut, so that the cutting knives 4 can better cut the pin.

[0087] In addition, since the pin is fixed, the cut pin is not easy to be bounced out in all directions due to the shearing stress of the cutting knives 4 when being cut. After the cutting knives 4 are cut, the two cutting knives 4 move in the direction of moving away from each other, so that the clamping block 92 moves in the direction of moving away from the abutting block 91. The cut pin will directly fall into the collecting box 5 along the inclined groove 811 under the action of gravity.

[0088] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
