Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic gas cylinder production and manufacturing, and in particular relates to an improved structure of a cylinder head stretching machine with auxiliary feeding and pushing functions. Background Art

[0002] Hydraulic gas cylinders are containers for storing high-pressure gas. At present, the production process of hydraulic gas cylinders is as follows: 1. Stretching to make the head; 2. Butt welding the two heads to form the bottle body; 3. Tempering the bottle body; 4. Water pressure testing; 5. Shot blasting to remove rust; 6. Spray coating on the surface; 7. High-temperature curing.

[0003] In the process of stretching and manufacturing the heads of hydraulic gas cylinders, the steel plates are loaded between the upper and lower modules of the stretching machine and are formed by punching. In the existing technology, the loading work of the cylinder head manufacturing is done manually by the operator. The steel plates are heavy, which not only increases the workload of the operators, but also requires the operators to frequently put their hands between the upper and lower modules of the stretching machine, which poses a safety hazard. Once an accident occurs, it will cause extremely serious personal losses. In addition, the upper and lower modules of the stretching machine are extremely hot during operation, which can easily burn the operators.

[0004] The stamped cylinder head falls from the bottom of the lower module. In the existing technology, after the fallen cylinder head falls on the base under the lower module, it is pulled out by the operator barehanded. The problems caused by this are: 1. In the process of the operator pulling out the cylinder head, if the operator moves a little slowly, he will be injured by the next falling cylinder head. 2. The temperature of the newly stamped cylinder head is relatively high, and the operator must wear gloves or use other tools to perform the unloading operation, which is extremely inconvenient. 3. The high-temperature cylinder head falls directly onto the hard base, which not only makes a loud noise when unloading, but also the bottom of the cylinder head is easily bumped and deformed, affecting product quality. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides an improved structure of a cylinder head stretching machine with auxiliary loading and pushing, which solves the problems of high loading intensity, potential safety hazards and inconvenient pushing operation of the existing cylinder head stretching machine.

[0006] The present invention is realized by an improved structure of a steel cylinder head stretching machine with auxiliary feeding and pushing, comprising a lower module, characterized in that:

[0009] The two loading side frames in this structure can guide the steel plate of the cylinder head, and the loading bracket can support the steel plate, which can not only make the steel plate slide accurately onto the lower module block, but also accurately fall into the processing position under the action of the limit block. Compared with the traditional manual loading of steel plates, it is more efficient. In addition, the operator can complete the loading by pushing the edge of the steel plate, which greatly reduces the depth of the operator's exploration into the inner side of the stretching machine during the loading process and reduces safety hazards.

[0010] The present invention is provided with a buffer component, which can buffer the falling cylinder head, prevent the cylinder head from directly falling on a hard base, ensure product quality, and reduce material discharge noise. In addition, the material discharge cylinder provided in the present invention can automatically push the cylinder head to discharge, and at the same time work in conjunction with the buffer component to prevent the buffer component from interfering during the discharge of the cylinder head. The present invention can realize the automatic discharge of the cylinder head, which has a high degree of automation compared to traditional manual operation and eliminates safety hazards.

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] In order to solve the problems of high loading intensity, potential safety hazards and inconvenient material pushing operation of the existing steel cylinder head stretching machine, the present invention provides an improved structure of a steel cylinder head stretching machine with auxiliary loading and pushing. The present invention can reduce the workload of operators and eliminate potential safety hazards during the loading process. In order to further illustrate the structure of the present invention, the detailed description is as follows in conjunction with the accompanying drawings:

[0028] The invention discloses an improved structure of a steel cylinder head stretching machine with auxiliary feeding and pushing functions, comprising a feeding mechanism 1 and a pushing mechanism 2.

[0029] See also Figure 1 and Figure 2 , including a lower module 1-1. As is well known to those skilled in the art, the lower module of the cylinder head stretching machine is a cylinder, and a stretching die hole is provided at the center of the cylinder.

[0030] Two loading side frames 1-2 are symmetrically arranged on the side of the lower module. In this embodiment, the loading side frames are L-shaped steel sections, the ends of the loading side frames are welded to the lower module, and the loading side frames are arranged horizontally. The loading side frames are close to the upper end of the lower module and are welded to the lower module.

[0031] The feeding side frame is provided with a guide side plate, which is a vertical plate body of the L-shaped feeding side frame. The two feeding side frames form a guide groove for guiding the steel plate used as the cylinder head stretching material to the lower module.

[0032] Two feeding brackets 1-3 are arranged between the two feeding side frames. In this embodiment, the feeding brackets are L-shaped steel sections. The ends of the feeding brackets are welded to the lower module. The feeding brackets are arranged horizontally. The feeding side frames are welded close to the upper end of the lower module. The feeding side frames are arranged parallel to the feeding side frames.

[0033] The feeding support frame is evenly provided with feeding rollers 1-4, and the axes of the feeding rollers are perpendicular to the extension direction of the feeding side frame.

[0034] In this embodiment, the feeding bracket is evenly distributed along its extension direction with a number of through holes with horizontal axes and perpendicular to the extension direction of the feeding bracket, and bolts are installed in the through holes, and the bolts are coaxial with the through holes. The bolts are sleeved with bearings as the feeding rollers. After the bearings are sleeved on the bolts, they are installed on the bolts through nuts mounted on the bolts. All rollers installed on the feeding bracket are required to ensure that the upper end surfaces are on the same horizontal plane, and this horizontal plane is higher than the upper end surface of the lower module, so as to ensure that the steel plates supported by the rollers can slide and fall onto the upper end surface of the lower module.

[0035] The outer periphery of the lower module is fixed with limit blocks 1-5. The limit blocks are welded on the lower module, and the inner section of the limit block weld is an arc-shaped limit surface.

[0036] Place the steel plate on the roller, and the operator pushes the steel plate away from the side of the stretching machine until the steel plate slides into the upper end surface processing station of the lower block of the stretching machine under the limiting guide of the loading side frame. Using this loading mechanism, the operator only needs to gently push the outer side of the steel plate to complete the loading operation. The operation is quick and easy, and there is no need to put both hands and most of the body close to the upper and lower modules of the stretching machine, avoiding safety hazards.

[0037] See also Figure 6 and Figure 7 , a column 2-1 is provided at the lower part of the lower module, a base 2-2 is fixed on the column, and the base is located below the lower module. As is well known to those skilled in the art, the lower module is a cylindrical module with a die hole, and the base is a cylindrical base. In this embodiment, the lower module and the base are fixed to the column by bolts. The column serves as a supporting component for the two.

[0038] At least three groups of buffer components are evenly distributed on the base in a circumferential direction with the center of the base as the center. In this embodiment, four groups of buffer components are installed on the base.

[0039] The buffer assembly includes a vertical telescopic rod 2-3, which is inserted into the base through a perforation. This structure enables the vertical telescopic rod to move in a vertical up-and-down direction under the guidance of the perforation. In this embodiment, the vertical telescopic rod is a metal rod body with a rectangular cross section.

[0040] The upper end of the vertical telescopic rod is hinged to a buffer support plate 2-4 extending radially along the base through a pin shaft. The axis of the pin shaft is horizontally arranged. The buffer support plate is a metal plate.

[0041] A buffer spring 2-5 is installed between the buffer support plate and the vertical telescopic rod. That is, the upper end of the buffer spring is hooked and installed on the buffer support plate, and the lower end of the buffer spring is hooked and connected to the vertical telescopic rod.

[0042] The upper surface of the base is provided with receiving grooves 2-6 at positions corresponding to the buffer support plates. The function of the receiving grooves is to allow the buffer assembly to be lowered as a whole and embedded therein. Therefore, when designing the dimensions, the width of the buffer support plate is greater than the width of the buffer spring and the vertical telescopic rod, and the width of the receiving grooves is slightly greater than the width of the buffer support plate. In this embodiment, the four receiving grooves are radially distributed outward from the center of the base, and the through holes for guiding the vertical telescopic rod are provided at the bottom of the receiving grooves.

[0043] The lower end of the vertical telescopic rod is connected to the lifting frame 2-7. In this embodiment, the lifting frame is a metal disc, and the lifting frame is welded to the lower end of the vertical telescopic rod.

[0044] An ejection spring 2-8 is installed between the lifting frame and the base. The lower end of the ejection spring is hooked on the lifting frame, and the upper end of the ejection spring is hooked on the lower part of the base. The ejection spring provides an upward extending force for the buffer assembly.

[0045] In this embodiment, the horizontal position of the hinged end of the buffer support plate is higher than the other end thereof. The four buffer support plates form a supporting structure for supporting the central depression of the cylinder head, ensuring the stability of the support after the cylinder head falls.

[0046] The lifting frame is connected to the driving rod 2-9. In this embodiment, the side of the lifting frame is welded to the lower end of the driving rod.

[0047] The upper end of the driving rod extends to the upper part of the base. In this embodiment, a guide hole is provided on the base, and the driving rod is inserted into the guide hole and extends to the upper part of the base.

[0048] The upper end of the driving rod is provided with a wedge-shaped pressing block 2-10. In this embodiment, the wedge-shaped pressing block is a nylon material block, which is fixed to the upper end of the driving rod by screws.

[0049] A pushing cylinder 2-11 is provided on the side of the wedge-shaped pressing block, and the pushing cylinder is fixed on the base by a bracket.

[0050] The push cylinder has a cylinder rod that can extend toward the center of the base. A wedge-shaped pressing plate 2-12 combined with the wedge-shaped pressing block is fixed on the cylinder rod. A sleeve is installed on the cylinder rod, and the wedge-shaped pressing plate is connected to a horizontal plate by screws, and the other end of the horizontal plate is screwed to the wedge-shaped pressing plate. The front part of the wedge-shaped pressing plate and the side of the wedge-shaped pressing block close to the wedge-shaped pressing plate are provided with mutually matching wedge-shaped surfaces.

[0051] When the rod of the push cylinder extends, the wedge-shaped pressure plate squeezes the wedge-shaped pressure block. Under the action of the wedge surface, the wedge-shaped pressure block is squeezed and moved downward, so that the driving rod drives the lifting frame and the buffer assembly to move downward as a whole. The rod of the push cylinder continues to extend, and the buffer assembly is stored in the storage groove of the base as a whole. The cylinder head supported by the buffer support plate falls onto the base. The rod of the push cylinder continues to extend until the cylinder head is pushed out from the bottom of the lower module to realize material discharge.

[0052] Embodiment 2

[0053] In this embodiment, a mechanism for auxiliary clamping of steel plate material is added on the basis of the first embodiment to completely prevent any part of the operator's body from being close to the upper and lower modules of the stretching machine, thereby completely eliminating safety hazards. The details are as follows:

[0054] See also Figure 3-Figure 5 The loading side frame is provided with a slideway 1-6 extending in the same direction as the loading side frame. In this embodiment, the slideway is a slideway with a dovetail-shaped cross-section and is fixed to the loading side frame by screws.

[0055] The two feeding side frames are respectively equipped with a left slider 1-7 and a right slider 1-8 which can slide along the slide through the slide, and the lower parts of the left slider and the right slider are provided with a dovetail groove matching the dovetail slide.

[0056] The left slider and the right slider are connected via a gate-shaped bridge frame 1-9, which is a steel frame, and both ends of the gate-shaped bridge frame are respectively fixed to the left slider and the right slider via screws.

[0057] The left clamping plate 1-10 is fixed on the left slide, and the left clamping plate is a side plate parallel to the guide side plate of the loading side frame, and its front end extends to the vicinity of the lower module. The left clamping plate is welded and fixed to the left slide by a metal rod.

[0058] The right slider is fixed with a plunger 1-11, and a feed side frame near the plunger is provided with a slide groove extending in the same direction as the feed side frame, through which the plunger passes, and a handle 1-12 is fixed at the outer end of the plunger passing through the slide groove. In this embodiment, the inner end of the plunger is welded to the right slider, and the outer end of the plunger is welded to the handle.

[0059] The right clamping plate 1-13 is inserted on the insertion rod, and the right clamping plate is a side plate parallel to the guide side plate of the feeding side frame, and its front end extends to the lower module. The end of the right clamping plate away from the lower module is processed with a socket, and the insertion rod is inserted into the socket.

[0060] A spring 1-14 is provided between the right clamping plate and the right slider, and the spring is sleeved on the plunger. The two ends of the spring press the right slider and the right clamping plate, and apply a force to the right clamping plate to move away from the left clamping plate.

[0061] The handle is hingedly connected to the pull handle 1-15 by a pin shaft, and the axis of the pull handle is vertical. The end of the pull handle close to the right clamping plate passes through the slide slot and touches the right clamping plate. When the operator pulls the pull handle, the lever moves away, and the end of the pull handle presses the right clamping plate to reduce the distance between the left clamping plate and the right clamping plate, thereby achieving the clamping of the steel plate between the left clamping plate and the right clamping plate.

[0062] The steel plate is loaded from the end of the loading bracket away from the lower module. When the steel plate moves to the end of the loading bracket close to the lower module, the operator pulls the handle to clamp the steel plate at the front end of the left clamping plate and the right clamping plate. Push the handle, the left and right sliders slide along the slideway, so that the steel plate is sent to the top of the lower module, loosen the handle and pull it back to complete the loading.

[0063] In order to enable the left clamping plate and the right clamping plate to clamp the steel plate more stably, clamping heads are fixed to the front ends of the left clamping plate and the right clamping plate, and clamping grooves are provided on the opposite surfaces of the two clamping heads.
