Technical Field

[0001] The invention belongs to the technical field of machining machine tools, and in particular relates to a forming machine tool for machining metal workpieces. Background Art

[0002] Machine tools refer to machines used to manufacture machines, and are generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. There are many methods for processing mechanical parts in modern machinery manufacturing: in addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. However, all parts with high precision requirements and fine surface roughness requirements generally need to be finally processed by cutting on machine tools. Machine tools also include lathes, drilling machines, boring machines, milling machines, planing machines, etc. At present, with the development of computers and CNC technology, more and more machine tools have realized CNC automation.

[0003] Currently, there are many cast iron materials in mechanical equipment, which are metal workpieces to be processed. In order to facilitate the installation or assembly of other accessories on the metal workpieces, holes need to be drilled, and most of the holes are completed by CNC drilling machines. Traditional CNC drilling machines will generate a large amount of dust and iron chips when drilling through the drill bit. Due to the open drilling environment, dust and iron chips will fly everywhere, affecting environmental hygiene and making it difficult to clean. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a forming machine tool for processing metal workpieces to solve the problem that dust and iron chips are discharged and fly during drilling in existing forming machines, which are difficult to clean and affect the environment.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A forming machine tool for processing metal workpieces, comprising a machine body of a drilling machine, wherein the machine body is connected to a drill bit via a connecting head, the drill bit being capable of being raised and lowered, and a processing base being provided below the drill bit, wherein a top surface of the processing base is provided with a plurality of radially extending slide grooves along a circumferential direction, each slide groove being connected to a clamping fixture, and further comprising a closing cover connected to the connecting head and positioning the drill bit within the closing cover; the lower end of the closing cover is open and forms a sealing contact end, the sealing contact end being provided with at least two deformation notches along a circumferential direction, each deformation notch extending in a height direction so that the sealing contact end forms a radially movable sealing contact portion between each two adjacent deformation notches; an elastic sealing member is provided within the deformation notch;

[0007] The top surface of the processing base constitutes a contact base surface; a movable sealing member is slidably fitted in the slide groove, and the movable sealing member has a contact surface for contacting the sealing contact portion, the contact surface being connected and flush with the contact base surface, so that when the sealing contact portion contacts the contact surface, the contact surface, the contact base surface and the sealing cover together constitute a sealing structure for sealing the space inside the sealing cover;

[0008] The enclosing cover is connected with a suction device which is in communication with the inner space of the enclosing cover.

[0009] In a possible implementation, the movable seal and the sealing contact portion form a magnetic attraction relationship, so that when the sealing contact portion moves radially, the movable seal and the sealing contact portion move synchronously.

[0010] In a possible implementation, the movable seal is made of an iron material, and a magnet is provided on the inner or outer side of the sealing contact portion, and the magnet corresponds to the movable seal and is magnetically engaged with the movable seal.

[0011] In a possible implementation, a limiting protrusion is provided at one end of the movable seal facing away from the clamping fixture, and the limiting protrusion and the contact surface together form a positioning groove.

[0012] In a possible implementation, the sealing contact portion is an arc-shaped structure, which enables a smooth transition between the inner side and the outer side of the sealing cover;

[0013] The positioning groove is adapted to the sealing contact portion.

[0014] In a possible implementation, the elastic sealing member is made of rubber material;

[0015] The closing cover is made of transparent material.

[0016] In a possible implementation, the enclosing cover is circular or square;

[0017] The closure cover is provided with at least a connecting section, a mounting section and a sealing section in sequence from top to bottom along the axial direction, wherein a through connecting hole is provided on the top end face of the connecting section, and the connecting section is detachably connected to the outer side of the connecting head through the connecting hole; the mounting section is connected to the suction end of the suction device; the sealing section constitutes a sealing contact end, and the deformation notch is provided in the sealing section.

[0018] In a possible implementation, the suction device is used to suck metal chips generated by the drill bit during the drilling process;

[0019] The sealing section is provided with a plurality of vents on the side opposite to and adjacent to the suction end of the suction device, respectively. The vents are lower than the suction end so that during suction, the airflow entering the closed cover through the vents can pass through the workpiece clamped in the clamping fixture and then enter the suction end.

[0020] In a possible implementation, the mounting section is further connected to at least one cooling air nozzle, and an air outlet end of the cooling air nozzle is located on the inner side of the closed cover.

[0021] In a possible implementation, the suction device includes a separator and a heater;

[0022] In which, the separator has a separation chamber, a filter is provided in the separation chamber, and the separation chamber is separated into an air inlet chamber and an air outlet chamber by the filter; the air inlet chamber is connected to the closed cover through a suction pipe, and the bottom of the air inlet chamber is detachably connected to a metal chip collection bottle; a fan is provided in the air outlet chamber, and the air outlet chamber is connected to the heating channel in the heater, a heating wire is provided in the heating channel, and the heating channel has an exhaust port.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. By arranging a closing cover on the outside of the drill bit, the sealing contact end of the closing cover can move radially when the drill bit is pressed down or raised through a multi-petal movable structure, so that it can be closed at drilling positions at different heights with the drill bit. During radial movement, the elastic sealing member can synchronously elastically seal with its radial movement, so that it can form a seal in the circumferential direction, and the sealing contact portion of the closing cover can move synchronously with the movable sealing member slidingly arranged in the slide groove, and then form an annular sealing surface that moves radially with the sealing contact portion with the contact base surface of the processing base, thereby avoiding the problem that the slide groove affects the sealing. The sealing effect is better in the form of surface contact, and the dust and iron chips generated by drilling can be effectively prevented from entering the air and affecting the environment. At the same time, the dust and iron chips in the closing cover can be better cleaned and collected by the suction component, and the cleaning is convenient and quick.

[0025] 2. By adopting the contact method of magnetic adsorption, when the sealing contact part moves radially, the movable seal can move synchronously, so that the sealing contact part can achieve surface sealing at different contact positions, ensuring the effectiveness and reliability of the seal, thereby avoiding the problem of the slide groove affecting the seal. The design is ingenious, reasonable and effective, and by arranging a limiting protrusion on the movable seal, it can be more convenient to position and synchronously move the movable seal.

[0026] 3. The closing cover is made of transparent material, which makes it easy to observe the internal processing during the closing process, which is more conducive to drilling. The closing cover can be square or round, and can be better expanded under pressure and elastically contracted through multiple deformation notches, which can not only provide an adaptive space for drilling, but also can be adjusted synchronously with the depth of drilling.

[0027] 4. By setting the suction end of the suction device at the mounting section of the closed cover and cooperating with the vents arranged on the opposite and adjacent sides, the incoming airflow can flow from low to high and from the peripheral side through the metal workpiece heated by drilling, and the heat of the metal workpiece is sucked away by the fast airflow, thereby achieving a better cooling effect on the metal workpiece, thereby improving the drilling quality and the life of the drill bit.

[0028] 5. By simultaneously arranging a cooling air nozzle on the closed cover, compared with the liquid cooling method, it also has a good cooling effect, can reduce the wear of the drill bit, and is easier to clean than the cutting coolant. In addition, the suction device can also be used to synchronously suck the cooling air while cooling it. While realizing the cooling effect of the cooling air, it can also accelerate the flow of the cooling air and improve the cooling effect.

[0029] 6. The suction device can not only perform suction, but also separate impurities such as dust and iron filings from the gas. The separated gas can be discharged. If it is cooling air, it can also be discharged after heating to avoid the problem of low-temperature air affecting the ambient temperature and causing cold air harm to people.

DETAILED DESCRIPTION

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0040] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] Please refer to Figure 1-8 As shown, an embodiment of the present application provides a forming machine tool for processing metal workpieces, including a machine tool body 1 of a drilling machine, the machine tool body 1 is connected to a drill bit 4 through a connecting head 3, the drill bit 4 can be raised and lowered, and the machine tool body 1 is provided with a processing base 2 below the drill bit 4, and the top surface of the processing base 2 is provided with a plurality of radially extending slide grooves 23 along the circumferential direction, and each slide groove 23 is connected to a clamping fixture 22.

[0042] The drilling machine can be a CNC drilling machine, which primarily uses a drill bit 4 to drill holes in metal workpieces. The drill bit 4 can be raised and lowered to adjust the drilling depth. The processing base 2 is used to place the metal workpiece. Specifically, the metal workpiece is clamped and fixed by a clamping fixture 22 provided on the top of the processing base 2. The clamping fixture 22 can be moved horizontally and vertically via circumferentially distributed slide grooves 23 to adjust the drilling position.

[0043] However, due to such open drilling conditions, the dust and iron filings generated by drilling will enter the air and fly everywhere, affecting environmental hygiene and making it difficult to clean.

[0044] In order to solve the above-mentioned technical problems, in an embodiment of the present application, the forming machine tool also includes a closing cover 5, which is connected to the connecting head 3 and allows the drill bit 4 to be located inside the closing cover 5; the lower end of the closing cover 5 is open and forms a sealing contact end, and the sealing contact end is provided with at least two deformation notches 58 along the circumferential direction, and each deformation notch 58 extends along the height direction so that the sealing contact end forms a sealing contact portion 56 capable of radial movement at the position between each adjacent two deformation notches 58; an elastic sealing member 59 is provided in the deformation notch 58.

[0045] The closure hood 5 is connected to the connector 3, allowing the drill bit 4 to be located within the closure hood 5 and move synchronously when the connector 3 and drill bit 4 are raised or lowered. Of course, the interior space of the closure hood 5 must be sufficient to cover the metal workpiece, the clamping fixture 22, and the drill bit 4, and also have a suitable height to ensure sealing under different usage conditions. The closure hood 5 forms a multi-petal movable structure through a deformable notch 58 on the circumferential side of the sealing contact end. This movable structure can expand with the processing base 2 when the drill bit 4 is pressed down, and can return to its original position due to a certain elastic property when it is raised, thereby ensuring that the closure hood 5 can always cooperate with the processing base 2 to achieve a sealing effect during different drilling processes. The deformable notch 58 is elastically sealed by an elastic sealing member 59, which can adapt to the deformation state of the elastic notch at different times, thereby achieving an elastic seal and allowing the closure hood 5 to be sealed circumferentially.

[0046] Correspondingly, the top surface of the processing base 2 constitutes a contact base surface 24; a movable seal 21 is slidably fitted in the slide groove 23, and the movable seal 21 has a contact surface 211 for contacting the sealing contact portion 56, and the contact surface 211 is connected and flush with the contact base surface 24, so that when the sealing contact portion 56 contacts the contact surface 211, the contact surface 211, the contact base surface 24 and the closing cover 5 together constitute a sealing structure for closing the inner space of the closing cover 5; the closing cover 5 is connected to a suction device 6 that is connected to the inner space of the closing cover 5.

[0047] Through the above technical solution, a closing cover 5 is provided on the outside of the drill bit 4. The sealing contact end of the closing cover 5 can move radially when the drill bit 4 is pressed down or raised through a multi-petal movable structure, so as to facilitate sealing at drilling positions of different heights with the drill bit 4. During radial movement, the elastic seal 59 can synchronously elastically seal with its radial movement, so that it can form a seal in the circumferential direction, and the sealing contact portion 56 of the closing cover 5 can move synchronously with the movable seal 21 slidingly arranged in the slide groove 23, and then form an annular sealing surface that moves radially with the sealing contact portion 56 with the contact base surface 24 of the processing base 2, thereby avoiding the problem that the slide groove 23 affects the sealing. The sealing effect is better in a face-to-face contact manner, which can effectively prevent dust and iron filings generated by drilling from entering the air and affecting the environment. At the same time, the dust and iron filings in the closing cover 5 can be better cleaned and collected through the suction component, and the cleaning is convenient and quick.

[0048] In one embodiment, the movable sealing member 21 and the sealing contact portion 56 form a magnetic attraction relationship, so that when the sealing contact portion 56 moves radially, the movable sealing member 21 and the sealing contact portion 56 move synchronously.

[0049] By adopting the contact method of magnetic adsorption, when the sealing contact part 56 moves radially, the movable seal 21 can move synchronously, so that the sealing contact part 56 can achieve surface sealing at different contact positions, ensuring the effectiveness and reliability of the seal, thereby avoiding the problem of the slide groove 23 affecting the seal. The design is ingenious, reasonable and effective.

[0050] Furthermore, to achieve a magnetically attracted contact method, the movable seal 21 can be made of an iron material, and a magnet 57 is provided on the interior or exterior side of the sealing contact portion 56. The magnet corresponds to and magnetically engages with the movable seal 21. In addition to this magnetic attraction, the movable seal 21 can also be made of a magnetic material, such as a neodymium magnet. By virtue of the principle that opposites attract, the movable seal 21 can move with the radial movement of the sealing contact portion 56, thereby ensuring a sealing effect.

[0051] To better synchronize the movement and positioning of the movable seal 21 and the sealing contact portion 56, a stopper protrusion 212 is further provided on the end of the movable seal 21 facing away from the clamping fixture 22. The stopper protrusion 212 and the contact surface 211 together form a positioning groove. The provision of the stopper protrusion 212 on the movable seal 21 further facilitates the positioning and synchronized movement of the movable seal 21.

[0052] Specifically, the sealing contact portion 56 is an arc-shaped structure that allows for a smooth transition between the inner and outer surfaces of the closure cover 5; the positioning groove is adapted to fit within the sealing contact portion 56. This contact structure allows the positioning groove to match the sealing contact portion 56, enabling surface contact under varying degrees of depression or extension.

[0053] In a specific embodiment, the elastic seal 59 is made of a rubber material, and the sealing cover 5 is made of a transparent material. The transparent material of the sealing cover 5 facilitates viewing of the internal processing during the sealing process, thereby facilitating drilling. Of course, the elastic seal 59 is not limited to rubber and can also be other elastic seals that can achieve the same sealing effect. The sealing requirement does not need to be completely sealed; it only needs to be able to prevent dust and metal chips from escaping.

[0054] In some other embodiments, the sealing cover 5 may be circular or square.

[0055] The sealing cover 5 can be square or circular. Multiple deformation notches 58 facilitate better expansion under pressure and elastic contraction, providing space for drilling and allowing for synchronous adjustment with the depth of the drilling. When the sealing cover 5 is circular, at least four deformation notches 58 are provided along the circumference, preferably as many as possible. This reduces the stress generated by each sealing contact portion 56 during downward pressure and expansion. When the sealing cover 5 is square, each side of the sealing cover forms a sealing contact portion 56. This eliminates the need for excessive stress and allows for a consistent number of deformation notches 58 along the sides.

[0056] In the embodiment of the present application, the closure cover 5 is provided with at least a connecting section 51, a mounting section 52, and a sealing section 53, sequentially arranged axially from top to bottom. The top end surface of the connecting section 51 is provided with a through-hole 5100, and the connecting section 51 is detachably connected to the outside of the connector 3 via the connecting hole 5100. The mounting section 52 is connected to the suction end of the suction device 6 via a mounting hole 510 and a sealing connection sleeve 54 disposed within the mounting hole 510. The sealing section 53 constitutes a sealing contact end, and the deformation notch 58 is provided in the sealing section 53. In this way, the closure cover 5, through its segmented structure, can more rationally and cooperatively connect to the suction device 6, the connector 3, and the sealing contact end.

[0057] In order to achieve cooling during the processing of metal workpieces, the suction device 6 is mainly used to suck metal chips generated by the drill bit 4 during the drilling process; the sealing section 53 is respectively provided with a plurality of ventilation holes 55 on the side opposite to and adjacent to the suction end of the suction device 6, and the ventilation holes 55 are lower than the suction end, so that during suction, the air flow entering the closed cover 5 through the ventilation holes 55 can pass through the workpiece clamped in the clamping fixture 22 and then enter the suction end.

[0058] In this way, by setting the suction end of the suction device 6 on the mounting section 52 of the closed cover 5, and cooperating with the vent holes 55 set on the opposite side and the adjacent side, the incoming airflow can flow from low to high and from the peripheral side through the metal workpiece heated due to drilling, and the heat of the metal workpiece is sucked away by the fast airflow, thereby achieving a better cooling effect on the metal workpiece, thereby improving the drilling quality and the life of the drill bit 4.

[0059] Furthermore, in order to achieve better cooling, the mounting section is further connected to at least one cooling air nozzle 7 , and the air outlet end of the cooling air nozzle 7 is located on the inner side of the closed cover 5 .

[0060] By simultaneously arranging a cooling air nozzle 7 on the enclosing cover 5, a good cooling effect is achieved compared to the liquid cooling method, and the wear of the drill bit 4 can be reduced. It is also easier to clean than the cutting coolant, and the suction device 6 can also synchronously suck the cooling air while cooling it. While realizing the cooling effect of the cooling air, it can also accelerate the flow of the cooling air and improve the cooling effect.

[0061] In a preferred embodiment of the suction device 6, the suction device 6 may include a separator and a heater 67; wherein the separator has a separation chamber, a filter screen 64 is provided in the separation chamber, and the separation chamber is divided into an air inlet chamber 62 and an air outlet chamber 63 by the filter screen 64; the air inlet chamber 62 is connected to the closed cover 5 through a connecting suction pipe 61, and a metal chip collection bottle 65 is detachably connected to the bottom of the air inlet chamber; a blower 66 or a fan is provided in the air outlet chamber 63, and the air outlet chamber 63 is connected to the heating channel in the heater 67, a heating wire is provided in the heating channel, and the heating channel has an exhaust port 68.

[0062] The suction device 6 can not only perform suction, but also separate impurities such as dust and iron filings from the gas. The separated gas can be discharged. If it is cooling air, it can also be discharged after heating to avoid the low-temperature air affecting the ambient temperature and causing cold air harm to people. When in use, the cooling air nozzle 7 can be selected to open according to the processing conditions or processing requirements of the metal workpiece.

[0063] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
